Article: Evaluation and management of fatigue in oncology: a multidimensional approach.
[show abstract] [hide abstract]
ABSTRACT: Fatigue, one of the most common symptoms experienced by cancer patients, is multidimensional and is associated with significant impairment in functioning and overall quality of life. Although the precise pathophysiology of cancer-related fatigue (CRF) is not well understood, a number of metabolic, cytokine, neurophysiologic, and endocrine changes have been described in these patients. A better understanding of these abnormalities is likely to lead to novel therapeutic interventions. Clinically, all patients presenting with significant fatigue should be evaluated for treatable conditions that might contribute to this symptom. Exercise and treatment of anemia are the two most established interventions for CRF. Psychostimulants seem promising based on early studies. Several complementary medicine treatments that showed efficacy in preliminary studies merit further testing.Indian Journal of Palliative Care 05/2011; 17(2):92-7. -
Article: Systemic treatment and targeted therapy in patients with advanced hepatocellular carcinoma.
[show abstract] [hide abstract]
ABSTRACT: ADVANCED HEPATOCELLULAR CARCINOMA (HCC) IS A MALIGNANCY OF GLOBAL IMPORTANCE: it is the sixth most common cancer and the third most common cause of cancer-related mortality worldwide. Despite decades of efforts by many investigators, systemic chemotherapy or hormone therapy has failed to demonstrate improved survival in patients with HCC.. Ongoing studies are evaluating the efficacy and tolerability of combining Sorafenib with erlotinib and other targeted agents or chemotherapy. On the basis of placebo-controlled, randomized phase III trials, Sorafenib has shown improved survival benefits in advanced HCC and has set a new standard for future clinical trials. The successful clinical development of Sorafenib in HCC has ushered in the era of molecularly targeted agents in this disease, which is discussed in this educational review. Many molecularly targeted agents that inhibit angiogenesis, epidermal growth factor receptor, and mammalian target of rapamycin are at different stages of clinical development in advanced HCC. Future research should continue to unravel the mechanism of hepatocarcinogenesis and to identify key relevant molecular targets for therapeutic intervention. Identification and validation of potential surrogate and predictive biomarkers hold promise to individualize patients' treatment to maximize clinical benefit and minimize the toxicity and cost of targeted agents. Systemic therapy with various classes of agents, including hormone and cytotoxic agents, has provided no or marginal benefits. Improved understanding of the mechanism of hepatocarcinogenesis, coupled with the arrival of many newly developed molecularly targeted agents, has provided the unique opportunity to study some of these novel agents in advanced HCC. The demonstration of improved survival benefits by Sorafenib in advanced HCC has ushered in the era of molecular-targeted therapy in this disease, with many agents undergoing active clinical development.North American journal of medical sciences. 04/2011; 3(4):167-75. -
Article: [Intestinal non-Hodgkin lymphoma: "immunoproliferative small intestinal disease"].
[show abstract] [hide abstract]
ABSTRACT: Immunoproliferative small intestinal disease (IPSID), also known as alpha chain disease, is a rare disease. In the recent WHO classification of hematopoietic and lymphoid tissue, IPSID is considered as a variant of extranodal mucosa-associated lymphoid tissue (MALT) lymphoma. Campylobacter jejuni is a specific pathogen, found to be related to IPSID. Diagnosis is based on histology and immunochemistry (± fluorescent in situ hybridization), with presence of many variable levels of abnormal immunoglobulin in the serum, identified to be truncated alpha-heavy chains. Early-stage disease is treated by antibiotics (tetracyclines). Chemotherapy is recommended up front for patients with advanced disease at presentation or refractory to antibiotics. The chemotherapy schedule used is the CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) regimen.La Presse Médicale 03/2011; 40(11):995-1000. · 0.67 Impact Factor -

ABSTRACT: La maladie de HODGKIN (MDH) survient le plus souvent chez les enfants, adolescents et jeunes adultes. Elle représente une des tumeurs malignes les plus curables. Grâce aux progrès thérapeutiques actuels, plusieurs patients ont pu obtenir des réponses complètes durables, mais les tumeurs solides malignes, secondaires au traitement, demeurent la complication tardive la plus redoutable chez les longs survivants. Il s'agit d'un patient de 28 ans, sans antécédents pathologiques notables, suivi depuis l'age de 13 ans pour une MDH scléro-nodulaire stade IV (à localisation pulmonaire). Le patient a reçu initialement 06 cures de chimiothérapie, suivies d'une radiothérapie externe sus et sous-diaphragmatique. L'évolution a été marquée par la survenue de 02 rechutes, pour lesquelles, 02 autres lignes thérapeutiques ont été administrées. Puis, survenue d'une progression, pour laquelle il a été mis sous Cyclophosphamide par voie orale. Après 02 ans d'un bon contrôle clinique et radiologique sous cette dernière drogue cytotoxique, le patient a fait apparaître une hématurie macroscopique et parallèlement, un adénocarcinome (ADK) colique, survenant 15 ans après le début du traitement initial du lymphome, ayant nécessité une hémicolectomie droite élargie. Les modalités thérapeutiques de la MDH chez les adolescents et jeunes adultes ont subit des modifications remarquables ces dernières décennies. L'évaluation du risque de cancers secondaires chez les longs survivants, reflète souvent l'effet de modalités anciennes plus agressives. La plupart des études rapportant des cas de cancers secondaires, tiennent en compte la 1(ère) ligne thérapeutique et les traitements de rattrapage de la MDH. En effet, les jeunes patients traités par chimiothérapie et plus particulièrement par radiothérapie, sont à haut risque de développer des cancers secondaires. La radio-chimiothérapie parait par ailleurs, augmenter de façon plus significative ce risque. L'estimation du risque de cancers secondaires à long terme demeure alors essentielle, afin de minimiser les complications tardives, et ceci à travers des mesures de prévention et de dépistage chez les jeunes patients potentiellement à risque.The Pan African medical journal. 01/2011; 9:25. -
Article: Metastatic collecting duct carcinoma of the kidney treated with sunitinib.
[show abstract] [hide abstract]
ABSTRACT: Collecting duct carcinoma (CDC) of the kidney is a rare and aggressive malignant tumor arising from the distal collecting tubules which has been shown to have a poor response to several kinds of systemic therapy. We present a case of metastatic CDC that responded favorably to a multiple tyrosine kinase inhibitor, sunitinib, achieving a partial response in both lung and skeletal metastases. To our knowledge, this is the first report showing therapeutic activity of sunitinib against CDC. Considering these findings, it would be worthwhile prospectively investigating the role of multiple tyrosine kinase inhibitors, particularly sunitinib, in the management of metastatic CDC.World Journal of Surgical Oncology 01/2011; 9:73. · 1.12 Impact Factor -
Article: Advanced treatments in non-clear renal cell carcinoma.
[show abstract] [hide abstract]
ABSTRACT: To focus on the use of targeted therapies against the non-clear histologic subtypes of renal cell carcinoma (RCC); papillary I and II, chromophobe, and collecting duct. The unique genetic and molecular profiles of each distinct non-clear kidney cancer subtype will be described, as these differences are integral to the development and effectiveness of the novel agents used to treat them. Materials and On the basis of MEDLINE database searches, we assessed all aspects of targeted therapy in non-clear cell RCC between 2000 and 2010. Trials focusing on non-clear RCC or those that treated clear cell tumors along with significant numbers of non-clear subtypes will be discussed. The role of cytoreductive nephrectomy and the use of neoadjuvant and adjuvant targeted therapy will be reviewed. Lastly, areas of future research will be highlighted. The majority of clinical trials testing novel targeted therapies have excluded non-clear subtypes, providing limited therapeutic options for patients with these diagnoses and their oncologists. Patients presenting with advanced non-clear pathology should undergo a thorough metastatic evaluation and, if appropriate, surgical evaluation to determine if nephrectomy, lymphadenectomy, and/or metastectomy are warranted. Aggressive surgical extirpation is often recommended. Sunitinib also is adequately tolerated and oncologically active in subjects with non-clear histology.Urology journal 01/2011; 8(1):1-11. · 0.58 Impact Factor -
Article: Thyroid carcinoma presenting as a dural metastasis mimicking a meningioma: A case report.
[show abstract] [hide abstract]
ABSTRACT: Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. We report a case of a 41-year old man presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect. After magnetic resonance imaging (MRI) a suspect diagnosis of meningioma was made. The patient underwent surgery where a soft mass with transverse sinus invasion was encountered; the tumour was successfully resected employing microsurgical techniques. Histological examination revealed a thyroid follicular neoplasm with positive staining for follicular carcinoma in immunohistochemical analysis. Postoperatively levels of thyroid hormones were normal. Treatment was planned for the thyroid gland, patient receiving 6 courses of chemotherapy including paclitaxel. The present case emphasizes that although they are uncommon, dural metastasis can be mistaken for meningiomas. The definitive diagnosis of a meningioma should be established only after the histopathological analysis. Thyroid follicular carcinoma should be included in the differential diagnosis in cases of extrinsic tumoral lesions.North American journal of medical sciences. 01/2011; 3(1):39-42. -
Article: Transitional cell carcinoma of the ovary: a rare case and review of literature.
[show abstract] [hide abstract]
ABSTRACT: Transitional cell carcinoma (TCC) of the ovary is a rare, recently recognized, subtype of ovarian surface epithelial cancer. A 69-year-old postmenopausal woman presented with a 2-year history of progressive enlargement of an abdominal mass. Abdominal computed tomography showed a pelvic mass. CA-125 was normal. A staging operation with total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy and pelvic lymph node dissection was performed. After surgery, the pathologic report of the right ovarian tumour was TCC, grade 3, stage IC. The patient underwent 3 cycles of chemotherapy: carboplatin and paclitaxel. She is regularly followed up and has been disease free for 10 months Transitional cell carcinoma (TCC) of the ovary is a rare subtype of epithelial ovarian cancer. Surgical resection is the primary therapeutic approach, and patient outcomes after chemotherapy are better than for other types of ovarian cancers.World Journal of Surgical Oncology 11/2010; 8:98. · 1.12 Impact Factor
