Description

Clinical and Translational Oncology is an international journal devoted to fostering interaction between experimental and clinical oncology. It covers all aspects of research on cancer, from the more basic discoveries dealing with both cell and molecular biology of tumour cells, to the most advanced clinical assays of conventional and new drugs. In addition, the journal has a strong commitment to facilitating the transfer of knowledge from the basic laboratory to the clinical practice, with the publication of educational series devoted to closing the gap between molecular and clinical oncologists. Molecular biology of tumours, identification of new targets for cancer therapy, and new technologies for research and treatment of cancer are the major themes covered by the educational series. Full research articles on a broad spectrum of subjects, including the molecular and cellular bases of disease, aetiology, pathophysiology, pathology, epidemiology, clinical features, and the diagnosis, prognosis and treatment of cancer, will be considered for publication. Case reports describing unusual clinical cases or examples of unique reports dedicated to translational research will also be within the scope of the journal.

  • Article: FP3: a novel VEGF blocker with antiangiogenic effects in vitro and antitumour effects in vivo
    [show abstract] [hide abstract]
    ABSTRACT: BackgroundVascular endothelial growth factor (VEGF) is a critical promoter of blood vessel growth during embryonic development and neovascularisation in tumours. VEGF serves as a logical target for antiangiogenic cancer therapy because of its fundamental role in tumour angiogenesis. This study is to investigate the inhibitory effects of FP3, a novel VEGF blocker, on angiogenesis in vitro and tumour growth in vivo. MethodsThe inhibitory effects of FP3 on angiogenesis in vitro were evaluated by using human umbilical vein endothelial cells (HUVECs) and rat aortic ring. The inhibitory effects of FP3 on tumour growth and angiogenesis in vivo were evaluated in a human non-small-cell lung cancer (NSCLC) cell line A549 tumour xenograft model with the methods of tumour growth regression assay and immunohistochemical staining, respectively. ResultsIn experiments with HUVECs, FP3 inhibited cell proliferation and migration. In rat aortic ring assay, FP3 suppressed VEGF-induced vessel sprouting. In tumour growth regression assay, FP3 significantly blocked the growth of A549 tumour in the subcutaneous tumour xenograft model and dramatically decreased the vessel density of tumour. ConclusionsFP3 has excellent inhibitory effects on tumour angiogenesis both in vitro and in vivo, therefore it could be used as an effective antiangiogenic agent.

  • Article: Transthoracic oesophagectomy with lymphadenectomy in 100 oesophageal cancer patients. Multidisciplinary approach
    [show abstract] [hide abstract]
    ABSTRACT: ObjetivesAnalysis of the results on the treatment of esophageal cancer by transthoracic esophagectomy by a multidisciplinary team of surgeons and oncologists. MethodsBetween January 1990 and December 2009, 100 consecutive patients underwent transthoracic esophagectomy. Data were collected prospectively and clinical, pathological and histological features of the tumors were analyzed as well as the results of postoperative morbidity and mortality. ResultsThe average patient age was 55 years (range 31–83 years). In 59 cases the tumor was located in the lower third and in 41 cases in the middle third. Forty-six patients had adenocarcinoma and 54 squamous cell carcinoma. In 54 cases radio-chemotherapy was planned preoperatively. Classification according to pathological tumor stage was: stage 0 in 21 patients, stage I in 10 patients, stage IIa in 28, stage IIb in 9, stage III in 21 and stage IV in 11. The mean number of lymph nodes examined was 14 (range 0–28). Hospital mortality occurred in 4 cases and postoperative complications in 29 patients (33%). The most frequent postoperative complication was pulmonary complications in 17 cases. The average hospital stay was 15.2 days (range 10–40 days) ConclusionsThe results of esophageal cancer have been improved in recent years due to the formation of multidisciplinary teams in this pathology. In our study we have shown that the results obtained with the transthoracic technique for cancer of the esophagus are within the ranges reported in the literature for teams with high prevalence of the disease.

  • Article: An epidemiological study of the perception of asthenia by oncologists in cancer patients: POA study
    [show abstract] [hide abstract]
    ABSTRACT: IntroductionDespite the high prevalence of asthenia in cancer patients, around 50–75%, and its impact on quality of life, it continues to be a difficult symptom to assess and manage. This study defines the extent of perception and diagnosis of asthenia associated with cancer among Spanish oncologists. MethodsA descriptive, observational study conducted in Spain based on a five-part structured questionnaire available to participants through a private website. ResultsThe 100 oncologists surveyed, most in the public healthcare setting, diagnose asthenia in 58–70% of cases. They consider old age (56.5%) and advanced-stage disease (94.2%) as factors associated with the occurrence of asthenia, which is also common in, particularly, tumours, such as pancreatic cancer (30.4%), and some therapies, notably chemotherapy alone (67%) or combined with radiotherapy (96%). Despite its adequate detection, physicians rarely ask their patients about asthenia, use instruments for its evaluation or assess its impact on quality of life. Likewise, only 40% of all patients are treated, although therapeutic intervention, a multidisciplinary approach combining drug and non-drug treatments and managing a variety of causative factors, can be considered adequate. Finally, 91.5% of those surveyed do not have action guidelines for asthenia in their hospitals. ConclusionsEven when asthenia is widely diagnosed in cancer patients in Spain, there is a laxity in its assessment and treatment. Increased awareness among healthcare professionals of its impact and relevance is therefore required, as well as adequate protocols for its systematic detection and management within the routine assessment and treatment of cancer patients.

  • Article: Radioquimioterapia de la enfermedad limitada del carcinoma pulmonar de célula pequeña. ¿Tratamiento concomitante en protocolos asistenciales?
    [show abstract] [hide abstract]
    ABSTRACT: PurposeWe retrospectively reviewed our institution’s database to investigate the outcome and impact of combined radiochemotherapy (RT/CT; concomitant or in sequence) in localised small-cell lung cancer (L-SCLC). Material and methodsBetween January 1995 to November 1999, 79 patients with L-SCLC received combined RT/CT at our Institution. RT was delivered concurrently or sequentially following the CT. Patients with treatment response received additional prophylactic cranial irradiation (PCI). ResultsOf the patients treated, 54% had received concurrent CT/RT compared to 46% receiving RT following the CT. PCI was administered to 80% of the patients. Complete response was observed in 66% of patients. With a median follow up of 30 months, median overall survival was 15.9 months; 14.3 months for patients who received RT following CT and 21.6 months for those receiving concurrent CT/RT. The type of schedule of combined radiochemotherapy was an independent prognostic factor for survival free of local recurrence, as was additional PCI for distant metastasis-free survival. ConclusionsOur results are similar to those reported previously in the literature. The main point of interest is that our patients were non-selected. We strongly support the use of concurrent CT/RT so as to achieve results comparable to the best in the literature.

  • Article: The Borrmann classification. Interobserver and intraobserver agreement of endoscopists in an oncological hospital
    [show abstract] [hide abstract]
    ABSTRACT: IntroductionThe Borrmann classification is used to describe advanced gastric cancer. Management strategies and prognostications are based on gross morphology of the cancer. The aim of this study was to evaluate inter- and intra-observer agreement using Borrmann's classification for advanced gastric cancer. Material and methodsImages (n=54) of advanced gastric cancer, including the 5 types of Borrmann classification, were taken from the records of the gastrointestinal endoscopy service of the National Cancer Institute (Instituto Nacional de Cancerología) and analysed by 4 endoscopists. The first pair of endoscopists (group 1) had experience of <1,000 endoscopy procedures and the second pair (group 2) had experience of >5,000 endoscopy procedures. The evaluation was blind in that none of the endoscopists involved knew the provenance of the images. The endoscopists were required to classify each lesion after they had agreed on the classification to be used, and its features. ResultsThe overall inter-observer agreement and significance was calculated with the Kappa statistic. The overall agreement of groups 1 and 2 was 48% and 57%, with a Kappa value of 0.58 and 0.80, respectively. The corresponding intra-observer agreement was 33% and 62%, with a Kappa value of 0.24 and 0.57, respectively. Type II and type III lesions on the Borrmann classification showed an overall agreement of 76% and 63%, with a Kappa value of 0.53 and 0.24, respectively. ConclusionsThese data suggest a lack of uniformity in defining the Borrmann classification for advanced gastric cancer; mainly of types II and III. Correct identification and characterisation of features via endoscopy provides the most valuable information. The high level of non-concordance is related to the training level. Consensus definitions of Borrmann's classification need to be developed and disseminated to ensure appropriate patient evaluation and a high level of agreement among endoscopists. IntroducciónLa clasificación de Borrmann se utiliza para describir el cáncer gástrico avanzado. Las estrategias de pronóstico y tratamiento se basan en la morfología macroscópica del cáncer. El objetivo de este estudio fue evaluar la concordancia en un mismo observador y entre distintos observadores cuando se utilizaba la clasificación de Borrmann para el cáncer gástrico avanzado. Material y métodosVarias imágenes (n=54) de cáncer gástrico avanzado, incluyendo los 5 tipos de clasificación de Borrmann, se tomaron de los registros del servicio de endoscopia gastrointestinal del Instituto Nacional de Cancerología y fueron analizadas por 4 endoscopistas. El primer par de endoscopistas (grupo 1) tenía una experiencia de <1.000 procedimientos endoscópicos y el segundo par (grupo 2) tenía una experiencia de >5.000 procedimientos endoscópicos. La evaluación se llevó a cabo a ciegas, en el sentido de que ninguno de los endoscopistas conocía la procedencia de las imágenes. A todos ellos se les pidió que clasificasen cada lesión después de estar de acuerdo en el tipo de clasificación empleado y sus características. ResultadosLa concordancia global entre distintos observadores y su significación se calculó con la estadística kappa. La concordancia global entre los grupos 1 y 2 fue de 48% y de 57%, con un valor kappa de 0,58 y 0,80, respectivamente. La concordancia en un mismo observador fue de 33% y de 62%, con un valor kappa de 0,24 y 0,57, respectivamente. Las lesiones de tipos II y III de la clasificación de Borrmann mostraron una concordancia global de 76% y de 63%, con un valor kappa de 0,53 y 0,24, respectiamente. ConclusionesEstos datos sugieren una falta de uniformidad en la definición de la clasificación de Borrmann para el cáncer gástrico avanzado, sobre todo de los tipos II y III. Una identificación y caracterización correctas de las características endoscópicas ofrecen la información más valiosa. El elevado nivel de no concordancia está relacionado con el nivel de entrenamiento. Es necesario el desarrollo y difusón de definiciones consensuadas de la clasificación de Borrmann para asegurar la evaluación apropiada del paciente, y un alto nivel de concordancia entre endoscopistas.

  • Article: SEOM guidelines: non-seminomatous germ cell cancer (NSGCC)
    [show abstract] [hide abstract]
    ABSTRACT: Non-seminomatous germ cell cancer (NSGCC) is a curable disease; its treatment has not essentially changed since the 1980s. BEP (bleomycin, etoposide, cisplatin) chemotherapy remains the standard of care. NSGCC’s management can be summarised by three trees of decision, which contemplate staging, treatment with chemotherapy and management of postchemotherapy residual disease. The role of high-dose chemotherapy remains to be established. TIP (paclitaxel, iposfamide, cisplatin) chemotherapy is still the standard salvage treatment for patients progressing after BEP chemotherapy. Surgical removal of any residual disease is mandatory. For patients with poor prognosis, consultation with a centre of expertise is strongly recommended. KeywordsGerm cell carcinoma–Staging–Treatment–Guidelines

  • Article: Estudio de la expresión de ciclina D1, p16, MIB-1 y p53 en lesiones precancerosas orales
    [show abstract] [hide abstract]
    ABSTRACT: ObjetivosConocer la expresión proteica de las alteraciones genéticas que se producen en las etapas precoces de la cancerización del campo de cavidad oral en nuestro medio. Estudiar la expresión proteica de MIB-1, ciclina D1, p16 y p53 para valorar si las alteraciones en la expresión proteica de estos marcadores suceden de forma secuencial a través de las distintas etapas en la cancerización del campo de cavidad oral. Material y métodosSe realizó un estudio mediante técnicas de inmunohistoquímica sobre 53 pacientes que presentaron lesiones de leucoplasia oral. Se incluyen en el estudio 11 muestras de epitelio normal, 15 displasias leves y moderadas, 15 carcinomasin situ y 12 carcinomas microinvasores. ResultadosEncontramos sobreexpresión de MIB-1, ciclina D1 y p53 y pérdida de expresión de p16 a medida que avanzamos en el grado de severidad histopatológica de las lesiones. Las alteraciones más precoces son sobreexpresión de MIB-1 y pérdida de expresión de p16 en displasias leves y moderadas. Hay diferencias significativas en la expresión de ciclina D1 entre displasias leves y moderadas y carcinomasin situ. ConclusionesLa leucoplasia oral es un estado precanceroso que constituye una lesión que se puede transformar en maligna debido a las alteraciones genéticas que intervienen en la evolución de la lesión. El estudio inmunohistoquímico y molecular de las lesiones es un medio rutinario que permite conocer la expresión proteica de las alteraciones genéticas, que puede ayudar en el diagnóstico precoz y tratamiento de esta patología, teniendo especial relevancia el estudio de p16 en etapas iniciales y p53 en lesiones más avanzadas. |AimsTo know the proteic expression of the genetic alterations that take place in the precocious stages of the field cancerization of oral cavity in our means. To study the MIB-1, cyclin D1, p16 and p53 expression levels to value if the alterations in the expression levels of these markers happen in a sequential pathway through the different stages in the field cancerization of oral cavity. |Material and methodsWe have studied by means of technical of immunohistochemistry on 53 patients with oral leucoplakia. They are included in the study 11 specimens of normal squamous epithelium, 15 mild and moderate dysplasias, 15in situ carcinomas and 12 microinvasive carcinomas. |ResultsOverexpression of MIB-1, cyclin D1 and p53 and loss of p16 expression was found as we increased in the grade of histopathological severity of the lesions. The most precocious alterations are overexpresion of MIB-1 and loss of p16 expression in mild and moderate dysplasic lesions. There are significant differences in the expression of cyclin D1 between light and moderate dysplasias andin situ carcinomas. |ConclusionsThe oral leucoplakia is a precancerous condition that constitutes a possible malignant transformation in oral carcinoma due to the genetic alterations that partipate in the evolution of the lesion. The immunohistochemistry and molecular study of the lesions is a routine means to make it possible to know the proteic expression of the genetic alterations that can help in the precocious diagnosis and treatment of this pathology, having special relevance the study of p16 expression in initial stages and p53 in more advanced lesions.

  • Article: Síndrome de supresión del antiandrógeno: estrategia terapéutica en el cáncer de próstata andrógeno-independiente
    [show abstract] [hide abstract]
    ABSTRACT: IntroducciónEl síndrome de supresión de antiandrógeno (AA) es un fenómeno bien conocido en el cáncer de próstata. Está ampliamente aceptado que un subgrupo de pacientes en progresión de la enfermedad en curso de terapia hormonal se beneficia de la retirada del antiandrógeno u hormona esteroidea, objetivándose un descenso en el antígeno prostático específico (PSA) y una mejoría clínica. En nuestro estudio, nos proponemos revisar nuestra experiencia en aquellos pacientes con cáncer de próstata en progresión de su enfermedad (cáncer de próstata andrógeno-independiente) y el efecto de retirada del antiandrógeno (valoración de respuesta, duración de respuesta) así como el análisis de posibles factores predictivos. Material y métodosEstudiamos 70 pacientes afectados de cáncer de próstata que presentaban progresión bioquímica de su enfermedad en curso de terapia hormonal y evaluamos la respuesta a la retirada del antiandrógeno, a los tres meses de su retirada, considerándose como respuesta la reducción de los valores del PSA en más del 50% de los iniciales. Asimismo, realizamos un análisis estadístico (prueba del Chi-cuadrado, prueba exacta de Fisher) de los posibles factores predictivos. ResultadosObservamos una disminución de más del 50% del PSA en 22 pacientes (31,4%), una estabilización de sus valores en 9 de ellos y progresión bioquímica en 39 (68,6%). La mediana de duración de la respuesta fue de 5 meses. Se evidenció un mayor porcentaje de respuestas a la retirada de la bicalutamida que a la retirada de la flutamida aunque la diferencia no llegaba a ser significativa. De todos los factores analizados, la duración de la hormonoterapia previa parece predecir la duración de la respuesta a la retirada del antiandrógeno. ConclusiónEl hecho de que cerca de un 30% de pacientes respondan a la retirada del antiandrógeno debe ser tenido en cuenta en el diseño de los ensayos clínicos: los pacientes que responden a esta maniobra hormonal experimentarán una mejoría en su calidad de vida de aproximadamente 6 meses. |IntroductionThe anti-androgen withdrawal syndrome is a well-established phenomenon in prostate cancer. It is widely accepted that a subset of patients will benefit from the withdrawal of anti-androgen or steroid hormone from hormonal therapy; the result being a decrease in prostate-specific antigen (PSA) values and clinical improvement. In our study, we review our experience in patients with prostate cancer in progression stage (androgen-independent prostate cancer) and the effect of anti-androgen withdrawal (evaluation of response; duration of response) as well as assessing the possible predictive factors. |Material and methodsWe studied 70 patients with prostate cancer in biochemical progression receiving hormonal therapy. We evaluated the response three months after anti-androgen withdrawal. Considered as response was the reduction of PSA levels of >50%. The Chi-squared test and the Fisher exact test were the statistical analyses used to identify possible predictive factors. |ResultsWe observed a PSA reduction of >50% in 22 patients (31.4%), a stabilisation of PSA levels in 9 of the patients, and biochemical progression in 39 patients (68,6%). The mean duration of response was 5 months. We observed a greater percentage of response to the withdrawal of bicalutamide than to flutamida, but the differences were not statistically significant. Only the duration of prior hormonal therapy appeared to predict the response to antiandrogen withdrawal. Currently, it is not possible to identify the subset of patients whose tumors will respond to anti-androgen or steroid withdrawal. Tumors that respond may be classified as androgen-independent and hormone-sensitive tumors as opposed to androgen-independent and hormone-insensitive tumors, which do not respond. Patients who respond to anti-androgen withdrawal experience an improved quality of life for approximately 6 months. However, it is not known whether this translates into prolonged survival. |ConclusionsSince about 30% of patients will respond to anti-androgen or steroid withdrawal in hormone-refractory prostate cancer, this needs to be taken into account in clinical trials of new cytotoxic agents. Cessation of flutamide for at least 4 weeks and, perhaps even 8 weeks in the case of bicalutamide, is mandatory before anti-androgen withdrawal syndrome can be excluded as the cause of a decrease in PSA values.

  • Article: Una propuesta práctica para seleccionar tratamientos quimioterápicos en pacientes oncológicos avanzados según su coste-efectividad
    [show abstract] [hide abstract]
    ABSTRACT: Fundamento. Unas mayores posibilidades de quimioterapia en pacientes avanzados obliga a seleccionar los estudios más apropiados. Presentamos una propuesta práctica basada en la eficacia y costeefectividad. Método. A partir de variables de eficacia, calidad de vida y de diseño del estudio es posible clasificarlo. Los costes diferenciales entre esquemas, por mes de supervivencia y por paciente vivo al año sirven para estimar el coste-efectividad. Resultados. Evaluamos 5 esquemas de uso frecuente en ovario, mama, pulmón, colon y cerebro que producen resultados discretamente positivos y más costosos: cada mes de aumento de la supervivencia mediana oscila entre los 1.500 y los 25.500 euros adicionales. Conclusión. La propuesta es aplicable y mejorará la toma de decisiones. Background. Higher possibilities of chemotherapy for advanced patients, made the selections of best studies necessary. A practical approach based on efficacy and cost-effectiveness is shown. Methods. Variables of efficacy, quality of life and type of study provide its classification. Differential costs between schemes, per months of survival and per one more patient alive one more year are used for the cost-effectiveness. Results. Five schemes broadly used in ovary, breast, lung, colon and brain tumours are evaluated. All of them produce a moderate improvement in outcomes and an increase in costs: per months of increment in median of survival require between 1,500 and 25,500 euros extra. Conclusion. This approach is useful for making decision process.

  • Article: Bioquimioterapia ambulatoria con cisplatino, dacarbacina, interleucina-2 e interferón-alfa en pacientes con melanoma avanzado. Estudio multicéntrico en 44 pacientes
    [show abstract] [hide abstract]
    ABSTRACT: FundamentoSe ha descrito una importante actividad (50% de respuestas objetivas) con un pequeño número de supervivientes en los ensayos clínicos de quimioinmunoterapia (QIT) para el melanoma diseminado. En la mayoría, la hospitalización era un requerimiento habitual. ObjetivosValorar la posibilidad de administración ambulatoria completa de la QIT dentro de un ensayo fase II multicéntrico con cisplatino+dacarbacina (DTIC) en un día, combinado con la administración subcutánea de interleucina-2+interferón-α en pacientes con melanoma metastásico. Pacientes y métodosLos ciclos, administrados cada 21 días, incluían cisplatino 80 mg/m2 y DTIC 800 mg/m2 intravenosos el día 1, con inyecciones subcutáneas de interleucina-2 9 millones UI/m2 del día 2 al 5 e interferón-a 5 millones IU/m2 del día 1 al 5. No se permitió la utilización de corticoides, salvo los 20 mg de dexametasona previo al cisplatino del día 1 como antiemético. Tras 6 ciclos, los pacientes sin progresión recibieron otros 6 ciclos de inmunoterapia sola. ResultadosSe han tratado 44 pacientes con melanoma metastásico. Hombres/mujeres: 30/14. Edad mediana: 47. Mediana de estado funcional (ECOG): 0 (0–2). Se han administrado 224 ciclos completos. La toxicidad fue aceptable: la toxicidad grado 3 incluyó náuseas (6% de los ciclos), vómitos (10%), fiebre (1%), neutropenia (1%), anemia (0,8%), astenia (2%), elevación de las transaminasas (0,8%) y elevación de la creatinina sérica (0,8%). La respuesta (39 pacientes evaluables después de tres o más ciclos, resto demasiado pronto): respuesta completa 4 pacientes (10,2 %), respuesta parcial 13 (33,3%); enfermedad estable 8 (20,5%), progresión 14 p (35,8%). Tras una mediana de seguimiento de 20 meses o hasta la muerte, la mediana de la supervivencia fue de 11,6 meses. ConclusionesLa actividad y limitada toxicidad de este régimen permite su uso ambulatorio. La superioridad de la QIT sobre cada una de las modalidades de tratamiento aisladas todavía ha de ser confirmada. BackgroundSignificant activity (50% objective responses) plus a small fraction of long term survivors have been reported in pilot trials of chemoinmunotherapy (CT-IT) for disseminated melanoma. Requirement for hospitalization is a major inconvenience. AimsTo assess the feasibility of fully ambulatory CT-IT with single-day cisplatine+dacarbacine (DTIC) combined with subcutaneous interleukin-2+interferon-a for patients (p) with metastatic melanoma in a multicenter phase II trial. Patients and methodsCourses, to be repeated every 21 days, included cisplatin 80 mg/m2 and DTIC 800 mg/m2, both iv on day 1, plus subcutaneous injections of interleukin-2 9 million/m2 IU, day 2 to 5 and interferon-a 5 million m2 IU day 1 to 5. No corticosteroids were allowed except for 20 mg dexamethasone before cisplatine on day 1 for antiemesis. After 6 courses p without progression received 6 additional courses of IT alone. Results44 p with metastasic melanoma have been treated. Male/female: 30/14. Median age: 47 years. Performance status (ECOG): 1 (0–2). Full doses of therapy have been delivered in 224 courses. Toxicity was acceptable: grade 3 toxicity included nausea (6% of courses), vomiting (10%), fever (1%), neutropenia (1%), anemia (0.8%), asthenia (2%), elevation of transaminases (0.8%) and elevation of serum creatinine (0.8%). Response (39 p evaluable after 3 or more courses; rest too early): complete response 4 p (10.2%); partial response 13 p (33%); stable disease 8 p (20.5%); progression 14 p (35.8%). With median follow-up of 20 months or to death, median survival was 11.6 months. ConclusionsThe activity and limited toxicity of this regimen allow its ambulatory use. The superiority of CT-IT over each modality alone remains to be confirmed.

    ABSTRACT: ObjectiveTo evaluate survival and relapse patterns in 13 patients with recurrent, or refractory, germ-cell tumours treated with high-dose chemotherapy (HDC) and with peripheral blood stem-cell support. Material and methodsAll patients were treated in a single centre and received a median of 9 cycles (range 3–13) of cisplatinum-based chemotherapy (CT). The protocol consisted of: a) induction with ifosfamide-based CT (EPI: VP16 120 mg/m2, ifosfamide 1.3 g/m2, cisplatinum 25 mg/m2×4 days); b) mobilisation of PBSC with of either G-CSF (10 ug/kg/day) in 2 patients or EPI plus G-CSF, and c) HDC (carboplatin 350 mg/m2, cyclophosphamide 1500 mg/m2, VP16 400 mg/m2×3 days). G-CSF (5 μg/kg) was administered until haematopoietic graft. Median age=32 years (range 20–52); tumours=10/11 testicular (1 seminoma), 2 mediastinal. HDC was administered 21 months (range 6–66) post-diagnosis. Inclusion criteria: failure to achieve CR with conventional CT (n=5 patients), poor-prognosis mediastinal tumour (n=1), first recurrence after cisplatinum and ifosfamide-based CT (n=2) and second or third relapse (n=5). At the conclusion of HDC, 9/13 patients were in CR, 1 patient did not receive HDC because CNS progression but was included for survival analysis. ResultsMedian times to graft were 9 and 13 days for leukocytes and platelets, respectively. Non-haematological toxicity was low and no therapy-related deaths occurred. Median disease free and overall survival were 19 and 30 months, respectively. Currently, 2 patients have not relapsed at 36 and 80 months. Previously-affected sites of disease were the unique sites of relapse in 5/11 (50%), concomitant distant relapse in 4/11 patients, CNS metastases in 1 patient. Rescue CT consisted of either oral VP16 or CBDCA/Taxol, which induced a new response in 6/10 patients. ConclusionsHDC achieves 20% improved survival in patients refractory to conventional chemotherapy and non-resectable tumours. No benefit was observed in HDC treatment in patients having only partial response to conventional chemotherapy. Relapse following HDC occurred mainly at previously affected sites. ObjectivoAnalizar los patrones de recidiva y supervivencia de 13 pacientes con tumores de células germinales (TCG) con refractariedad parcial a cisplatino o en segunda recidiva que recibieron quimioterapia a dosis altas (QDA) y soporte con células progenitoras hematopoyéticas periféricas. Material y métodosLa mediana de ciclos de quimioterapia (QT) convencional con cisplatino previa era de 9 (3–13). Tratamiento: a) inducción: QT tipo EPI (VP16 120 mg/m2, ifosfamida 1,3 g/m2, cisplatino 25 mg/m2×4 días); b) movilización de células progenitoras con factor estimulante de colonias de granulocitos (G-CSF) (10 ug/kg/día) en 2 pacientes o EPI+G-CSF, y c) QDA (carboplatino 350 mg/m2, ciclofosfamida 1.500 mg/m2, VP16 4.00 mg/m2×3 días). Se administró G-CSF (5 μg/kg) hasta el injerto hematopoyético (neutrófilos > 1×109/l). Edad media: 32 años (rango 20–52). Origen: mediastino 2, testicular 11 (1 seminoma). Criterio de inclusión: no respuesta completa (RC) con QT convencional en 5 pacientes, tumor mediastínico en 1, primera recidiva tras QT con cisplatino e ifosfamida en 2 casos y segunda y tercera recidivas en 5 pacientes. Nueve de trece pacientes estaban en RC al inicio de la QDA. Un paciente que se incluyó en el análisis de supervivencia no continuó a QDA por progresión precoz cerebral. ResultadosLa mediana de supervivencia libre de progresión fue de 19 m, global 40 m; 2 pacientes están libres de progresión a 36 y 80 m. Todos los pacientes transplantados en respuesta parcial (RP) progresaron en el primer año. Cinco de once pacientes en áreas afectas como única localización. Rescate: consistió de VP16 oral, EMA-CO o CBDCA/taxol, y proporcionó 6 de 10 respuestas, una de ellas mantenida a 4 años. ConclusionesLa QDA como rescate de pacientes no curables con QT convencional y no quirúrgicos proporcionó 20% de largos supervivientes. No observamos beneficio en el tratamiento con QDA cuando sólo se obtuvo RP con el tratamiento convencional. La mayoría de las recidivas tuvieron lugar en áreas previamente afectas y en la mayoría de los pacientes fueron aún quimiosensibles.

  • Article: Tratamiento adyuvante del carcinoma de recto
    [show abstract] [hide abstract]
    ABSTRACT: ObjectivoNeustro objetivo es analizar los resultados del tratamiento adyuvante en pacientes operados por un carcinoma rectal localmente avanzado, tratados con radioquimioterapia concomitante o secuencial. Material y métodosEntre enero de 1994 y septiembre de 1997, 122 pacientes fueron tratados postquirúrgicamente por un adenocarcinoma rectal en estadio B2-C. Setenta y siete pacientes fueron tratados siguiendo un esquema alternante de quimiorradioterapia y 45 siguiendo un esquema concomitante. Los fármacos empleados fueron 5-fluorouracilo (5-FU) y leucovorín en todos los casos y el volumen irradiado incluyó la pelvis hasta una dosis de 50 Gy con fraccionamiento estándar. ResultadosTras un seguimiento mediano de 68,9 meses, la supervivencia global, cáncer-específica y libre de recidiva a 5 años fue del 58,62%, 60,5% y 51,33%, respectivamente. La probabilidad de recidiva global a 5 años fue del 48,7% de recidiva local del 34,6% y de metástasis del 32,6%. El estadio ganglionar y el estadio según la clasificación de Astler-Coller fueron los principales factores pronósticos (p<0,0001). El esquema del tratamiento combinado no mostró influencia estadística. Un 20,5% de los pacientes presentó toxicidad aguda relevante, sin ningún caso de toxicidad grado 4, ni muertes atribuibles al tratamiento combinado. El uso de una técnica radioterápica de dos campos y la secuencia significativamente en la incidencia e intensidad de toxicidad aguda. Apareció toxicidad tardía grado 3 en 13 pacientes (10,6%); de éstos, 10 (8,2%) requirieron tratamiento quirúrgico para solucionar una obstrucción intestinal. ConclusionesPodemos concluir que, en nuestro medio, el tratamiento radioquimioterápico adyuvante en el carcinoma rectal es un tratamiento efectivo, con cifras de supervivencia, recurrencía y toxicidad similares a los príncipales trabajos publicados en la literatura, y sin influencia de la secuencia de combinación en dichas cifras. ObjectiveOur objective was to assess the value of adjuvant treatment of patients undergoing surgery for locally-advanced rectal carcinoma, treated with concomitant, or alternating, radiochemotherapy. Material and methodsBetween January 1994 and September 1997, 122 patients with B2-C rectal adenocarcinoma were treated with a post-operative scheme of radiochemotherapy which was alternating (n=77) or concomitant (n=45). The chemotherapy agents were 5-FU and leucovorin in all cases. Radiotherapy volume included pelvis and was administered in 25 fractions up to a total dose of 50 Gy. ResultsWith a median follow-up of 68.9 months, the overall survival, cancer-specific survival and disease-free survival at 5 years were 58.6%, 60.5% and 51.3%, respectively. The 5-year overall recurrence rate was 48.7%, local recurrence rate was 34.6%, and metastases rate was 32.6%. The nodal stage and the Astler-Coller classification stage were the main prognostic factors (p<0.0001). The combined treatment scheme showed no statistical influence on outcome. Severe acute toxicity occurred in 20.5% of patients, with no case of toxicity grade 4 nor any toxic deaths. Two-field radiotherapy technique and the sequence of combination of radiochemotherapy were predictive factors of acute toxicity, both in incidence and severity. Delayed grade 3 toxicity occurred in 15 patients (10.6%) and, of these, 10 patients (8.2%) required surgical treatment to resolve an intestinal obstruction. ConclusionsOur results indicate that adjuvant radiochemotherapy for rectal carcinoma is an effective treatment. The rates of survival, recurrence and toxicity are similar to other major published studies, and with the sequence of administration having no significant effect on outcomes.

  • Article: CHOP con intensificación de dosis en linfomas no Hodgkin agresivos
    [show abstract] [hide abstract]
    ABSTRACT: IntroducciónEl objetivo de neustro trabajo es analizar la seguridad, tolerabilidad, respuestas y supervivencia en pacientes con linfoma no Hodgkin agresivo administrando ciclofosfamida, doxorrubicina, vincristina y prednisona (CHOP) con intensificación de dosis. Material y métodosVeintiséis pacientes (p) con una mediana de edad de 53 años recibieron CHOP cada 14 días con apoyo de factores de crecimiento. El porcentaje de neutropenia grado III/IV fue de un 31%. La mediana de seguimiento fue de 20,7 meses (rango 3–43). ResultadosDieciséis p (61%) alcanzaron respuesta completa, 8 p (30,8%) respuesta parcial, un p (3,8%) enfermedad estable, y un p (3,84%) progresó. El porcentaje de respuesta global fue 92%, la mediana de tiempo libre de eventos fue 12,17 meses y la mediana de tiempo libre de eventos a dos años fue 42%. La mediana de supervivencia global no se alcanzó. Después de 51 meses la supervivencia global fue de 65%. ConclusiónEste esquema con intesnficación de dosis presenta una toxicidad aceptable y mejores resultados que el CHOP estándar en cuanto al porcentaje de respuestas y supervivencia global, pero sólo discretamente mejor en términos de supervivencia libre de enfermedad. IntroductionThe aim of this study was to analyse the safety, feasibility, response and survival using dose-intensified CHOP regimen in patients with aggressive non-Hodgkin lymphoma. Material and methodsPatients (n=26) with a median age of 53 years were treated with CHOP every two weeks and with G-CSF support. Haematologic toxicity grade III/IV neutropenia was 31%. The median follow-up was 20.7 months (range 3–43). ResultsComplete remission was achieved in 16 patients (61%), partial remission in 8 (30.8%), stable disease in 1 (3.8%), and one patient (3.84%) had disease progression. Overall response was obtained in 24 patients (92%). The median event-free survival (EFS) was 12.17 months. The median EFS at two years was 42%. The median overall survival (OS) has not been reached, as yet. After 51 months, the OS was 65%. ConclusionThis regimen with intensified doses is well tolerated, and the results are better than those achieved with the traditional CHOP with respects to response and OS, but only slightly better in terms of disease-free survival.

  • Article: ¿Cuál es la duración óptima de la quimioterapia paliativa en los pacientes con cáncer avanzado?
    [show abstract] [hide abstract]
    ABSTRACT: Actualmente la quimioterapia representa la principal opción terapéutica en los pacientes con cáncer avanzado. Su finalidad es paliativa, por lo que adquiere relevancia establecer un balance entre sus efectos positivos sobre la supervivencia y calidad de vida y aquellos negativos en forma de toxicidad, frecuentación hospitalaria y coste económico. Desconocemos si es mejor continuar la quimioterapia hasta la progresión de la enfermedad o bien administrarla de forma intermitente. Por ello hemos revisado los ensayos comparativos publicados al respecto. En el cáncer de mama metastático el tratamiento prolongado parece ofrecer ventajas sobre la supervivencia. Aunque no existen estudios suficientes en otras neoplasias, dos ensayos recientes apoyan el empleo de la terapia intermitente en el cáncer colorrectal y broncopulmonar avanzados. Chemotherapy still represents the treatment of choice for patients with advanced cancer and is mainly palliative in intent. Thus, positive effects on survival and quality of life should be balanced against the negative impact of toxicity, hospital frequentation and economic costs. It is not well known if continued therapy (until disease progression) is better than intermittent administration. A review of randomized trials assessing this question has been performed. Continued treatment seems to offer some survival advantages in metastatic breast cancer. Although there are no sufficient studies in other malignancies, two recent trials support the use of intermittent therapy in advanced non-small cell lung cancer and colorectal carcinoma.

  • Article: Variations in use of breast-conserving surgery by patient, hospital characteristics, and region: a multilevel analysis
    [show abstract] [hide abstract]
    ABSTRACT: We hare analysed the influence of patient and hospital characteristics and region, on the use of breast-conserving surgery (BCS) in Catalonia (Spain). Data for this study was obtained from the Catalan Hospital Discharge Data Base. The study period was 1995–1998. The Mantel-Haenszel test was used to examine overall trends in the use of BCS. A regression analysis was performed to assess the effect of period adjusted for patient, hospital characteristics, and area of residence on use of BCS, and a multilevel analysis was performed to consider possible associations between individual and aggregate level variables. BCS was carried out in 43% of women in the period 1995–98 and there was an increasing significant trend in its use. Multilevel analysis showed that age and hospital volume were significant predictors of the use of BCS, and hospitals with higher volumes of activity having higher rates of BCS relative to mastectomy. Despite the evidence demonstrating the effectiveness of breast conserving surgery, there are still considerable variations in its use, which may be in part due to physician attitudes. Changes in health care organisation to deal with low volume treatments at hospital level should be Se ha analizado si influyen las características del paciente, del hospital y de la región en la utilización de la cirugía conservadora de mama (CCM) en Cataluña (España). Los datos para este estudio se han obtenido de la base de datos del Informe de Alta Hospitalaria. El período de estudio es de 1995–1998. Se utilizó el test Mantel-Haenszel para analizar las tendencias del uso de 1a CCM. Se realizó un análisis de regresión para evaluar el efecto de período ajustado por paciente, características del hospital y área de residencia en la utilización de la CCM, así como un análisis multinivel para considerar las posibles, asociaciones entre las variables individuales y las variables agregadas. La CCM se llevó a cabo en un 43% de mujeres en el período 1995–1998 y se observó un incremento significativo en su utilización. El análisis multinivel mostró que la edad y el volumen de actividad del hospital eran predictores significativos en la utilización de la CCM y los hospitales con mayor actividad mostraban un mayor porcentaje de CCM con relación a la mastectomía. A pesar de la evidencia que demuestra la efectividad de la cirugía conservadora de mama todavía existen considerables variaciones en su utilización que pueden ser debidos, en parte, a la actitud del profesional. La aplicación de determinados cambios en la organización de la atención oncológica permitirán obtener unos mejores resultados.
