ABSTRACT: Prostate cancer (PCa) is the most common cancer in the male population in Western countries, second to skin cancer. Hormonal therapy allows long-lasting and effective control of cancer-related symptoms in advanced stages; however, in almost all patients with metastatic PCa the disease will progress when it becomes castration-resistant (CRPC). Chemotherapy with docetaxel was a turning point in CRPC, as, for the first time, it resulted in an increased survival time in comparison with mitoxantrone and prednisone. Combination therapy with docetaxel and prednisone is the first-line treatment of choice. Once the cancer has progressed, there is no clear alternative, although some new agents have shown promise in the treatment of this type of cancer. This review will provide an overview of the current status of CRPC, including clinical status, prognosis, firstline treatment and new second-line treatment options.

ABSTRACT: Hormonal therapy allows effective control of cancer-related symptoms in advanced stages. However, the disease will progress in almost all these metastatic prostate cancer patient until becoming resistant to androgen suppression. The emergence of new drugs will most probably have open up new expectations regarding the treatment of this cancer.
The aim of the present review has been to provide an overview of the current status of castration-resistant prostate cancer and to share the high expectations created with the new treatments.
Evidence was obtained from multidisciplinary meetings with the participation of urologists and oncologists, where they pooled the analysis of original articles in the literature and defined the content of the article.
Chemotherapy with docetaxel was a turning point in castration-resistant prostate cancer after the failure of hormonal therapy failure. For the first time, it achieved increased survival time in comparison with mitoxantrone and prednisone. Combination therapy with docetaxel and prednisone is the first-line choice treatment. Once the cancer has progressed, there is no clear alternative, although some novel agents have created expectations for the treatment of this type of cancer.
The range of therapeutic options for castration-resistant prostate cancer has increased dramatically with the arrival of new drugs. At present, cabazitaxel, and in the near future, abiraterone, have been found to be effective drugs in second-line treatment after progression to docetaxel, increasing survival by 2-4 months and reducing risk of death by 30-35%.

ABSTRACT: Management of muscle-invasive bladder cancer (MIBC) has changed little in the last twenty years. The gold standard treatment is still cystectomy, but it has a significant negative impact on quality of life. Bladder-preservation strategies can be used in some cases but patient selection for this approach remains unclear. New chemotherapy and biologic agents in combination with surgery or radiotherapy could improve results and these possibilities are currently under investigation.

ABSTRACT: INTRODUCTION Sunitinib, an oral, multitargeted receptor tyrosine kinase inhibitor, delays disease progression, with a median overall survival (OS) of more than 2 years, improves quality of life and is becoming the first-line standard of care for metastatic renal carcinoma (mRCC). PURPOSE To assess the economic value of sunitinib as fi rst-line therapy in mRCC within the Spanish healthcare system. METHODS An adapted Markov model with a 10-year time horizon was used to analyse the cost effectiveness of sunitinib vs. sorafenib (SFN) and bevacizumab/interferon-α (BEV/IFN) as first-line mRCC therapy from the Spanish third-party payer perspective. Progression-free survival (PFS) and OS data from sunitinib, SFN and BEV/IFN pivotal trials were extrapolated to project survival and costs in 6-week cycles. Results, in progression-free life-years (PFLY), life years (LY) and quality-adjusted life-years (QALY) gained, expressed as incremental cost-effectiveness ratios (ICER) with costs and benefits discounted annually at 3%, were obtained using deterministic and probabilistic analyses. RESULTS Sunitinib was more effective and less costly than both SFN (gains of 0.52 PFLY, 0.16 LY, 0.17 QALY) and BEV/IFN (gains of 0.19 PFLY, 0.23 LY, 0.16 QALY) with average cost savings/patients of €1,124 and €23,218, respectively. Using a willingness-to-pay (WTP) threshold of €50,000/QALY, sunitinib achieved an incremental net benefit (INB) of €9,717 and €31,211 compared with SFN and BEV/IFN, respectively. At this WTP, the probability of sunitinib providing the highest INB was 75%. CONCLUSION Our analysis suggests that sunitinib is a costeffective alternative to other targeted therapies as first-line mRCC therapy in the Spanish healthcare setting.

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.

ABSTRACT: A strong rationale supports the role of antiangiogenic drugs in urothelial cancer. This trial was designed to assess the activity of sunitinib as first-line treatment in patients with metastatic urothelial cancer ineligible for cisplatin and to explore molecular and imaging variables predictive of clinical benefit.
This was a multicenter phase II trial with sunitinib 50 mg daily in 4/2-week schedule. Eligibility criteria were as follows: creatinine clearance 30-60 ml/min, Eastern Cooperative Oncology Group Pperformance Sstatus of one or less, and adequate hepatic and hematologic function. Twelve circulating cytokines were evaluated at baseline and sequentially using Luminex xMAP(®) (Austin, TX). Baseline and treatment-related changes in perfusion were evaluated in a patient subgroup using contrast-enhanced computed tomography.
On intention-to-treat analysis, 38 patients showed 3 (8%) partial responses (PRs) and 19 (50%) presented with stable disease (SD), 17 (45%) of them ≥3 months. Clinical benefit (PR + SD) was 58%. Median time to progression (TTP) was 4.8 months and median overall survival 8.1 months. Toxicity was consistent with previous reports for sunitinib. Low interleukin-8 (IL-8) baseline levels were significantly associated with increased TTP. Baseline tumor contrast enhancement with >40 Hounsfield units was associated with clinical benefit.
This study highlights the potential role of the angiogenic pathway as a therapy target in urothelial cancer. Baseline IL-8 serum levels and contrast enhancement of lesions warrant further study.

ABSTRACT: To determine the activity and toxicity of temozolomide in a phase II multicenter trial in patients diagnosed with relapsed or cisplatin-refractory germ cell tumors.
During a recruitment period of 30 months, 20 patients received temozolomide 150 mg/m(2)/day p.o. for 5 days every 4 weeks, escalating to 200 mg/m(2)/day if grade II toxicity was not observed in the first cycle. Eligibility criteria were tumor progression or relapse after previous cisplatin and ifosfamide-containing chemotherapy, creatinine clearance of >40 ml/min, and a performance status of 0-2.
The median age was 38 years (range 27-56). Seventeen patients had nonseminomatous tumors, and 3 had seminomatous tumors. Six of the patients had extragonadal primary tumors (3 retroperitoneal and 3 mediastinal). The median number of prior cisplatin-containing cycles was 11 (range 7-20). Eight patients received prior high-dose chemotherapy and 14 were refractory or absolutely refractory to cisplatin. A total of 45 cycles were administered. Two partial responses lasting 9 and 3.5 months (overall response rate 10%, 95% CI 1.2-31.7) were observed. One of these responses was seen in a patient with a cisplatin-refractory tumor that had previously been treated with high-dose chemotherapy. The median time to progression and the median overall survival were 1.5 and 3.1 months, respectively. Grade III hematological toxicity consisted of thrombocytopenia in 2 patients and anemia in 1 patient. No grade IV toxicity was observed.
Temozolomide had some activity in heavily pretreated patients resistant to cisplatin-based chemotherapy.

ABSTRACT: M-VAC (cisplatin, methotrexate, adriamycin, vinblastine) combination chemotherapy has been for long time the standard of care in fit patient with advanced urothelial tumors. Gemcitabine/cisplatin with similar results and an improved toxicity profile has proved to be a new standard alternative. Whether or not we can improve survival with newer triplet regimens will depend upon the results of ongoing phase III trials. In addition to the new active drug combinations and targeted therapies, new approaches are emerging for treatment. Chemotherapy optimization using molecular markers predicting chemosensitivity are being applied. There is an obvious need to incorporate in clinical trials a systematic translational approach to explain both our successes and our failures.

ABSTRACT: The Spanish Germ Cell Group is composed of 60 centres. Our challenge was to define a surveillance protocol that would be safe and suitable regardless of population size or geographic coverage.
From January 1994 to January 2004, 589 patients with stage I non-seminomatous germ cell tumours entered a risk-adapted surveillance protocol after orchiectomy. Patients with vascular or local invasion of adjacent structures (231/589; 39%) received two cycles of BE400P (bleomycin 30 U/week, etoposide 100 mg/m2 x4, cisplatinum 25 mg/m2 x4). Other patients (358/589; 61%) were kept on close follow-up (chest X-ray; serum tumour markers: first year every 2 months, second year every 3 months, third year every 4 months; abdominal computed tomography scans at every other outpatient control). The outcomes selected for the study were feasibility, relapse rate and number of patients lost to follow-up and mortality.
Median follow-up was 40 months. In the surveillance group, 21 patients were lost to follow-up. In the chemotherapy group, two patients relapsed at 12 and 14.5 months and they are presently free of disease. In the surveillance group, 71 (19%) patients relapsed, of which 55 (71%) relapsed within the first year. Five (1.4%) patients died of their cancer. Factors associated with relapse were embryonal carcinoma and vascular invasion in patients who refused chemotherapy.
Our risk-adapted surveillance protocol provided a low rate of recurrences.

ABSTRACT: After decades of irradiation as standard therapy for clinical stage I testicular seminoma, alternative treatment approaches have emerged including postorchiectomy surveillance and adjuvant chemotherapy. This study was performed to assess a dual policy of surveillance and selective single-agent carboplatin (for high-risk cases) in a multicenter setting.
From 1994 to 1999, 203 patients with stage I seminoma were included. Sixty (29.6%) were considered poor-risk cases (i.e. with vascular invasion and/or pathological tumor stage pT2 or greater) and received two courses of adjuvant carboplatin, whereas 143 (70.4%) without risk criteria underwent close surveillance.
Median follow-up was 52 months (range 14-92). Relapses were observed in two (3.3%) patients treated with carboplatin and in 23 patients (16.1%) on surveillance, with a median time to recurrence of 11 months (range 3.9-39.6). All relapsing patients were rendered disease-free, mainly with cisplatin-based chemotherapy. Four patients died from tumor-unrelated causes. Actuarial 5-year overall survival was 96.7% and cause-specific survival was 100%. Five-year disease-free survival was 83.5% for patients on surveillance, and 96.6% for those receiving carboplatin.
This dual treatment policy is feasible in a multicenter setting and preserves 70% of patients from adjuvant chemotherapy. Single-agent carboplatin is effective in reducing the relapse rate in patients with high-risk stage I seminoma. A better definition of local risk features would probably improve patient selection, thus minimizing the incidence of recurrences on surveillance.

ABSTRACT: To describe the clinical characteristics and treatment results obtained with the application of a homogeneous treatment protocol in 1490 patients with germ-cell tumours (GCT) registered in the 55 hospitals belonging to the Spanish Germ-Cell Cancer Group (GG) during the period between January 1994 and April 2001.
In general, surveillance was the common policy for stage I patients without local poor prognosis factors, whereas they received adjuvant chemotherapy in case those factor were present. Chemotherapy schedules used in advanced cases were cisplatin and etoposide (EP) for seminoma and BEP or BOMP-EPI in non-seminoma, according to whether the patient was in the good or poor prognosis IGCCCG (International Germ-Cell Cancer Collaborative Group) group. Excision of residual masses was mandatory in non-seminomatous germ-cell tumour (NSGCT).
Initial local symptomatology was increased testis size in 90% of cases. Sonography was an excellent diagnostic tool to suggest tumour. Non-seminoma (64.2%) was more frequent than seminoma (35.8%). Approximately 10% had the antecedent of cryptorchidism. Non-seminoma patients were 7 years younger than seminoma. Right testis was involved predominantly. Pre-orchidectomy tumour markers were elevated in 21% of seminoma (betaHGC) and 79% in non-seminoma (alphaFP and/or betaHGC). Scrotum violation occurred in only 1.8%. There were significant differences among stage I and the IGCCCG prognosis groups related to a longer interval between the first symptom and orchiectomy. Eighteen percent of non-seminomatous germ-cell tumour belonged to the poor prognosis IGCCCG group. With a median follow-up to 33 months, this series has achieved a 3 year overall survival of 98% for seminoma and 94% for non-seminoma. Only 10% of excised residual masses present after chemotherapy contained malignant cells.
Spanish GCT have a similar clinical pattern to that described in the other occidental countries except for a slight increased proportion of non-seminoma upon seminoma. Co-operative groups as GG are unique structures to obtain quick and wide experience on the treatment of testis tumours, contributing to achieve a high cure rate.

ABSTRACT: A multicentre phase II trial was undertaken to evaluate the activity and toxicity of docetaxel plus cisplatin as first-line chemotherapy in patients with urothelial cancer. Thirty-eight patients with locally advanced or metastatic transitional-cell carcinoma of the bladder, renal pelvis or ureter received the combination of docetaxel 75 mg m(-2) and cisplatin 75 mg m(-2) on day 1 and repeated every 21 days, to a maximum of six cycles. The median delivered dose-intensity was 98% (range 79-102%) of the planned dose for both drugs. There were seven complete responses and 15 partial responses, for and overall response rate of 58% (95% CI, 41-74%). Responses were even seen in three patients with hepatic metastases. The median time to progression was 6.9 months, and the median overall survival was 10.4 months. Two patients who achieved CR status remain free of disease at 4 and 3 years respectively. Grade 3-4 granulocytopenia occurred in 27 patients, resulting in five episodes of febrile neutropenia. There was one toxic death in a patient with grade 4 granulocytopenia who developed acute abdomen. Grade 3-4 thrombocytopenia was rare (one patient). Other grade 3-4 toxicities observed were anaemia (three patients), vomiting (five patients), diarrhoea (four patients), peripheral neuropathy (two patients) and non-neutropenic infections (seven patients). Docetaxel plus cisplatin is an effective and well-tolerated regimen for the treatment of advanced urothelial cancer, and warrants further investigation.

ABSTRACT: The incidence and risk factors for fungal infection were assessed in 291 patients who had solid tumors and were undergoing autologous peripheral blood stem cell transplantation. The first 162 patients received prophylactic itraconazole, and 129 patients received nystatin. Empiric amphotericin B was given at day 7 of febrile neutropenia. Fungal infections developed in 52 patients: 47 (16%) were superficial and 6 (2%) were systemic. Itraconazole prophylaxis and only a few days of febrile neutropenia were independently associated with a decrease in the incidence of superficial infections. Only two patients required empiric amphotericin B. Systemic antifungal prophylaxis does not seem to be justified for patients with solid tumors and autologous peripheral blood stem cell transplantation. Empiric amphotericin B may be safely started at day 7 of febrile neutropenia.

ABSTRACT: Even its low incidence, germ-cell testicular cancer is very relevant due to its presentation at young ages and its potential curability over 90%. Spanish Germ Cell Cancer Group (GG) joins the efforts of 51 different Spanish centres to share their experience on the diagnosis and treatment of these special tumours.
We describe the clinical characteristics and the results of treatment in the first 1,250 patients registered throughout 6 years by the GG.
11% had previous criptorchidism. The most frequent initial local simptomatology was increased testis size (90%). 20% lasted more than six months in receiving the first treatment. Inguinal orquidectomy was done in 95% of patients. 435 cases (35%) were seminoma and 815 (65%)non-seminoma. 19% of seminoma and 78% of non-seminoma produced tumour markers. 75% of seminoma but only 56% of non-seminoma were clinical stage I. Following the IGCCCG prognosis classification,20% of non-seminoma fitted in the poor-prognosis group. Stage I seminoma treatment was surveillance, chemotherapy and complementary radiotherapy in 60, 32 and 6%, respectively. Those features were 65, 35% and none in non-seminoma cases. Chemotherapy schedules used in advanced cases were EP for seminoma and BEP or BOMP-EPIin non-seminoma, according to whether the patient was in the good or bad prognosis IGCCCG group. With a median of follow-up in all serie of 30 months, we have obtained a three years overall survival of 98% (CI 95%, 96,4-9,6), whereas non-seminoma patients had a three years overall survival of 94% (CI 95%, 92-96).
The Spanish germ cell testicular cancer clinical pattern is similar to that registered in other occidental countries. Co-operative structures like GG,are able to gather an extensive experience in a short period of time that results in achieving a very high number of cured patients.

ABSTRACT: The authors undertook a Phase II multicenter trial to assess the efficacy and toxicity of doxorubicin and paclitaxel in combination in the treatment of patients with metastatic breast carcinoma.
Doxorubicin (50 mg/m2, bolus) followed by paclitaxel (175 mg/m2 over 3 hours) was administered every 21 days (for a maximum of 10 cycles) as first-line chemotherapy in 77 patients, 41 of whom had received prior adjuvant chemotherapy. Monitoring of cardiac function (left ventricular ejection fraction[LVEF]) and total doxorubicin cumulative dose were included in the study protocol.
Grade 4 hematologic toxicities were neutropenia (58%) and thrombocytopenia (4%). Neutropenic fever occurred in 9% of patients. Nonhematologic Grade 4 toxicity was limited to mucositis (3%). Grade 3 toxicities were neutropenia (35%), anemia (3%), alopecia (93%), peripheral neuropathy (18%), arthralgia/myalgia (8%), and mucositis (9%). No clinical cardiotoxicity (Grades 3 or 4) occurred. Treatment was discontinued in 5 patients who showed a decrease of LVEF of greater than 15% during therapy. Of 73 patients assessable for response, 15 were complete response, 42 partial response, 15 stable disease, and 1 disease progression; overall response rate being 78% (95% confidence interval [CI], 67-87). Median follow-up was 22 months. Median time to progression (TP) was 10 months (95% CI, 7-12). Time to progression was poorer in cases with adjuvant anthracycline therapy than those without adjuvant chemotherapy (7 vs. 12.3 months; P = 0.022), but TP in patients with adjuvant chemotherapy not containing anthracyclines was not different from the cases without adjuvant chemotherapy (8.6 months). Estimated 2-year survival was 51% (standard error, 7%).
Our results confirm that the combination of paclitaxel and doxorubicin is effective in the treatment of metastatic breast carcinoma, and that it is well tolerated. No clinical cardiotoxicity was observed on close cardiac monitoring, and prior adjuvant anthracycline treatment compromised its efficacy.

ABSTRACT: The effect of an extensive prophylactic antimicrobial regimen was prospectively assessed in 126 patients after high-dose chemotherapy and autologous PBSC. They received ciprofloxacin (500 mg/12 h), acyclovir (200 mg/6 h), and itraconazole (200 mg/12 h) orally until neutrophil recovery. Febrile patients received i.v. imipenem (500 mg/6 h) to which vancomycin and amikacin were added if fever persisted for 2-3 and 5 days, respectively. Amphotericin B lipid complex was further given on day 7 or 8 of fever. Median times for a neutrophil count of >0.5 x 10(9)/l and a platelet count of >20 x 10(9)/l were 9 and 11 days. Severe neutropenia (<0.1 x 10(9)/l) lasted for a median of 5 days in which 72% of febrile episodes and 50% of cases of bacteremia occurred. Gram-positive bacteria were isolated in 30 of 40 episodes of bacteremia, 25 of which were caused by Staphylococcus epidermidis. Clinical foci were the intravascular catheter in 35 cases, respiratory infection in 11, cellulitis in two, anal abscess in one, and neutropenic enterocolitis in one. The high incidence of febrile episodes (94%) and bacteremias (31%) may be due to the lack of efficacy of antimicrobial prophylaxis and the persistence of a 5-day period of severe neutropenia.

ABSTRACT: To prospectively analyze factors that influence peripheral blood stem cell (PBSC) collection and hematopoietic recovery after high-dose chemotherapy (HDC), 39 patients received cyclophosphamide 4 g/m(2) and rHuG-CSF (Filgrastim) 5 &mgr;g/kg/day. Leukapheresis was started when CD34(+) cells/mL were > 5 x 10(3). A minimum of 2 x 10(6) CD34(+) cells/kg was collected. Median steady-state bone marrow CD34(+) cell percentage was 0.8% (range, 0.1 to 6). Thirty-two patients received HDC with autologous PBSC transplantation plus Filgrastim. A median of 2 (range, 0 to 6) leukapheresis per patient were performed and a median of 6.3 x 10(6) CD34(+) cells/kg (range, 0 to 44.4) collected; four patients failed to mobilize CD34(+) cells. The number of cycles of prior chemotherapy had an inverse correlation with the number CD34(+) cells/kg collected (r = -0.38; p < 0.005). Patients with <7 cycles had a higher predictability for onset of leukapheresis than patients with (3) 7 (93% versus 50%; p < 0.005). The four patients who failed to mobilize had received >/=7 cycles. The number of CD34(+) cells/kg infused after HDC had an inverse correlation with days to recovery to 0.5 x 10(9) neutrophils/L and 20 x 10(9) platelets/L (r = -0.68 and -0.56; p < 0.005). The effect of these factors on mobilization and hematopoietic recovery were confirmed by multivariate analysis. Requirements for supportive measures were significantly lower in patients given a higher dose of CD34(+) cells/kg. Therefore, PBSC collection should be planned early in the course of chemotherapy. Larger number of CD34(+) cells/kg determined a more rapid hematopoietic recovery and a decrease of required supportive measures.

ABSTRACT: To analyze the clinical outcome of patients diagnosed with growing teratoma syndrome (GTS) at a single center during a long follow-up.
Eleven patients with GTS are reported. GTS lesions were located in the metastatic sites involved at disease presentation. Involved sites were: retroperitoneum in 9 patients; lung in 3; supraclavicular lymph nodes in 2, and inguinal lymph nodes in 1. Surgical resection of the masses was the treatment of choice.
Twenty-four surgical procedures were performed: 4 thoracotomies; 2 supraclavicular; 1 inguinal, and 17 retroperitoneal node resections. Three patients have not relapsed since surgery of the masses, at 37+, 110+ and 118+ months. Eight patients have relapsed, 6 with mature teratoma and 2 (22%) with cancer. To date, all the patients are alive, 6 of them without disease and 5 with teratoma after resection of the masses.
GTS is an infrequent entity. Involved sites are only at locations previously affected by the disease. The treatment of choice is surgical resection but recurrence is common. Efforts should be done to complete resection of the masses.
