BackgroundBladder small cell carcinoma is an uncommon tumour. Through a retrospective study we will present the evolution of recurrent and metastatic disease and outcome of patients treated at Léon-Bérard Cancer Centre.MethodsOnly 15 patients having recurrent or metastatic bladder small cell carcinoma were treated at Léon-Bérard Cancer Centre between 1996 and 2007. The patients were divided in two groups: a mixed small cell carcinoma group (9 patients) and a pure small cell carcinoma group (6 patients). All the records and informations related to treatment and outcome of the 15 patients were retrospectively analyzed. Various characteristics of small cell carcinoma were investigated.ResultsThe median age of the 15 patients having recurrent or metastatic bladder small cell carcinoma and treated at Léon-Bérard Cancer Centre was 63 years and the disease was at stage IV for all cases. Nine patients were treated by chemotherapy. Four patients were treated by local radiotherapy (3 with radiotherapy without previous surgery and 1 with surgery followed by radiotherapy) and chemotherapy. One patient was treated by whole brain radiotherapy. And one patient died before treatment. After 52.4 months median follow up, 12 patients died. Median overall survival was 7.6 months. Survival probability at 1 year was 33%. Median overall survival was 9.9 months in the mixed small cell carcinoma group, and was only 4.6 months in the pure small cell carcinoma group. Survival probability at 1 year in the mixed small cell carcinoma group was 44% as compared to 17% in the pure small cell carcinoma group (Log-rank test: p = 0.228).ConclusionRecurrent and metastatic bladder small cell carcinoma is associated with very poor prognosis. The pure bladder small cell carcinoma appears to have poorer outcome than the mixed bladder small cell carcinoma. Chemotherapy using platinum drugs is a mainstay treatment.

BackgroundThis exploratory prospective study evaluated womens responses to questions that asked them to describe how their body image and sexual functioning had changed since their breast cancer diagnosis to treatment.MethodsA questionnaire concerning body image scale and various sexual problems experienced after diagnosis and treatment was anonymously completed by 120 women in the outpatient clinic of our hospitals Division of medical Oncology. To be eligible, subjects had to be sexually active and had histology proven breast cancer. They also had to have received treatment for breast cancer.Results100% of participants have never spoken with their doctor about this subject. 84% of the participants continued sexual activity after treatment, but there was an increase in the incidence of sexual functioning problems which resulted in a slight reduction in the quality of their sex lives. 65% of the women experienced dyspareunia followed by lubrication difficulties (54%) and the absence or reduction of sexual desire (48% and 64%, respectively) while, 37% had lack of satisfaction (37%). Female orgasmic disorder and brief intercourse and arousal were reported respectively by 40% and 38% of the subjects. The sexual dysfunctions were absent before diagnosis and management of breast cancer in 91.5% subjects and of these 100% subjects complained of a deterioration of the symptomatology after the various treatments. 90% of the dysfunctions were observed after chemotherapy, 9% after surgery and 3% after radiotherapy; none of the subjects indicated the onset of dysfunctions to have been associated with hormonotherapy. 100% expressed not having received sufficient information about how the disease and treatment (including surgery) might affect their sexual life.ConclusionBreast cancer and its treatment may result in significant difficulties with sexual functioning and sexual life. Addressing these problems is essential to improve the quality of life of Moroccan women with breast cancer.

BackgroundMale breast cancer (MBC) is a rare disease representing less than 1% of all malignancies in men and only 1% of all incident breast cancers. Our study details clinico-pathological features, treatments and prognostic factors in a large Moroccan cohort.FindingsOne hundred and twenty-seven patients were collected from 1985 to 2007 at the National Institute of Oncology in Rabat, Morocco.Median age was 62 years and median time for consultation 28 months. The main clinical complaint was a mass beneath the areola in 93, 5% of the cases. Most patients have an advanced disease. Ninety-one percent of tumors were ductal carcinomas.Management consisted especially of radical mastectomy; followed by adjuvant radiotherapy and hormonal therapy with or without chemotherapy. The median of follow-up was 30 months. The evolution has been characterized by local recurrence; in twenty two cases (17% of all patients). Metastasis occurred in 41 cases (32% of all patients). The site of metastasis was the bone in twenty cases; lung in twelve cases; liver in seven case; liver and skin in one case and pleura and skin in one case.ConclusionMale breast cancer has many similarities to breast cancer in women, but there are distinct features that should be appreciated. Future research for better understanding of this disease at national or international level are needed to improve the management and prognosis of male patients.

BackgroundTriple-negative breast cancer (TNBC) is defined by the lack of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) expression. This is an aggressive malignancy with a poor prognosis despite the high rates of response to chemotherapy. The aim of this study is to determine the clinicopathological, therapeutic features and outcomes associated with this type of breast cancer.MethodsThis is a retrospective study of confirmed triple negative breast cancer females collected at the National institute of oncology of Rabat in Morocco, between January 2007 and December 2008. Epidemiological, clinical, histological, therapeutic and evolutive data were analyzed. OS and DFS rates were estimated by Kaplan-Meier analysis.ResultsA total of one 152 patients with breast cancer, were identified as having triple-negative breast cancer (16,5%). The median age at diagnosis was 46 years. 130 patients (86%) had infiltrating ductal carcinoma and thirteen had medullar carcinoma (9%). 84 cases (55%) were grade III Scarff-Bloom-Richardson (SBR). 48 % had positive lymph nodes, and 5 % had distant metastases at diagnosis. According TNM staging, 12 patients (8%) had stage I, 90 patients (60%) had stage II and the 43(28%) had stage III. 145 patients received surgery. 41 (28%) had conservative surgery and 104 (72%) received radical mastectomy with axillary lymph nodes dissection. 14 patients with advanced tumors or inflammatory breast cancer have received neoadjuvant chemotherapy and four patients (28%) had complete pathologic response. From 131 patients how received adjuvant chemotherapy, 99 patients (75,5%) had Anthracycline based chemotherapy) and 27 patients (20,6%) had sequential Anthracycline and docetaxel,. Seven patients with metastatic disease received anthracycline-based regimen in the first line metastatic chemotherapy. The median follow-up time was 46 months (range 6,1 -60 months). Overall survival at 5 years for all patients was 76,5%.ConclusionThese results suggest that most TNBC characteristics in Moroccan patients are in accordance with literature data, especially concerning young age at diagnosis high grade tumors, advanced stage at diagnosis, and short time to relapse. Although the high response rate to chemotherapy, the overall prognosis of this subset of tumors remains poor.

Leiomyosarcoma of the thyroid gland.

Hamid Mansouri; Macoumba Gaye; Hassan Errihani; Fouad Kettani; Brahim Khalil El Gueddari

The existence of primary thyroid sarcomas represents a contentious issue. Some authors believe that thyroid sarcomas are, in fact, anaplastic carcinomas with sarcomatous (spindle cell) features. From the standpoint of treatment and prognosis, the histogenesis of thyroid ‘sarcomas’ is academic, because these tumors, irrespective of the therapeutic intervention, are lethal 1. Primary thyroid leiomyosarcomas are extremely rare. Only nine isolated cases have been reported in the literature and such tumors carry a very poor prognosis 1, 2, 3, 4, 5, 6, 7.

Involvement of the ovary by malignant lymphoma is a well-known late manifestation of disseminated nodal disease. Primary ovarian lymphoma is rare. We report a case of primary ovarian non-Hodgkins lymphoma with bilateral involvement which was managed by surgery and chemotherapy. A 29-year-old woman was admitted with signs and symptoms suggestive of an ovarian cancer. Computed tomography revealed an abdominal tumor measuring 20 cm in diameter, without enlarged lymph nodes. The diagnosis of malignant lymphoma was established after bilateral adnexectomy and histological study of the excised tissue. The tumor was classified as a diffuse large B-cell lymphoma. The patient has been advised 8 cycles of standard CHOP regimen and is presently on treatment. She has now been without disease for 7 months after the surgery. According to previous reports the treatment principles and prognosis of primary ovarian lymphoma is the same as that of other nodal lymphomas.

Introduction: Epidermal growth factor receptor (EGFR) mutations in non–small-cell lung cancer predict response to tyrosine kinase inhibitors. The frequency of EGFR mutations is ethnicity-dependent, with a higher proportion in Asian populations than in whites. The prevalence of these mutations among North African patients is unknown. The objective of this study was to report the frequency and spectrum of EGFR mutations in a group of Moroccan patients with lung adenocarcinoma (AC). Methods: Tumor specimens from 137 Moroccan patients with lung AC were selected to determine frequency and spectrum of EGFR mutations. Mutation detection techniques were polymerase chain reaction amplification and sequencing of exons 18, 19, 20, and 21. Results: The overall frequency of the EGFR mutation was 21%. Mutations were mainly detected in the exon 19 (69%), followed by exon 21 (21%) and exon 20 (7%), whereas mutations in the exon 18 were rare (3%). EGFR mutation rate was significantly higher in women and in never smokers. Conclusion: Some one fifth of lung AC tumors in Moroccan patients harbor EGFR mutations. This mutation frequency is higher than that found in whites but lower than in Asian population. Further studies, in larger numbers of patients, are needed to confirm these findings.

Metastatic Desmoplastic Small Round Cell Tumor Controlled by an Anthracycline-Based Regimen: Review of the Role of Chemotherapy

Hind Mrabti; W. Kaikani; N. Ahbeddou; Halima Abahssain; B. El Khannoussi; M. Amrani; Hassan Errihani

Desmoplastic small round cell tumors (DSRCT) are rare and aggressive malignant neoplasms that usually occur in young males. They usually present intraabdominally with widespread peritoneal involvement at diagnosis and are sometimes associated with lymphadenopathies and liver metastases. Intraabdominal DSRCT is usually disseminated; no curative outcome has yet been achieved. We report a case of metastatic intraabdominal DSRCT controlled by an anthracycline-based regimen. A literature review of the treatment options, mainly chemotherapy, available for this unusual neoplasm, will be discussed. In patients with unresectable or metastatic disease, symptom control is most important because treatment modalities minimally impact survival. Palliative chemotherapy (mainly monotherapy) is preferable.

Objectives: Only a few case reports and small case series of patients with sarcoidosis or sarcoid-like reaction and testicular germ cell tumors (GCT) have been reported in the literature. We performed a retrospective study of patients with testicular GCT managed at the Centre Léon-Bérard, who presented granulomatosis. Methods: We performed a computerized search to identify all male patients with both a diagnosis of sarcoidosis or granuloma and testicular tumors seen at the Centre Léon-Bérard between 1992 and 2008. Results: A total of 13 patients were identified among the 1,182 patients with testicular tumors. The median age at diagnosis of testicular GCT was 25.5 years. Six patients had stage I disease, 2 patients had stage IIb and 5 patients had stage III. Sarcoid-like granulomatosis was found in 9 patients at the time of initial diagnosis and in 4 patients during follow-up. Sarcoidosis presented mainly as pulmonary disease without severe organ involvement, with a benign evolution. Conclusion: We advise caution in the interpretation of clinical and histological findings in these patients. Sarcoid-like granulomatosis, a condition that can be combined with testicular cancer, should always be considered in the differential diagnosis of metastatic testicular tumors.

BackgroundThe optimal sequencing of chemotherapy and radiotherapy after breast surgery was largely studied but remains controversial. Concurrent chemo-radiotherapy is a valuable method for adjuvant treatment of breast cancer which is under ongoing research program in our hospital. We are evaluating the feasibility of the concomitant use of chemotherapy retrospectively.MethodsTwo hundred forty four women having breast cancer were investigated in a retrospective study. All patients were either treated by radical surgery or breast conservative surgery. The study compares two adjuvant treatments associating concomitant chemotherapy and radiotherapy. In the first group (group A) the patients were treated by chemotherapy and radiotherapy in concomitant way using anthracycline (n = 110). In the second group (group B) the patients were treated by chemotherapy and radiotherapy in concomitant way using CMF treatment (n = 134). Chemotherapy was administered in six cycles, one each 3 weeks. Radiotherapy delivered a radiation dose of 50 Gy on the whole breast (or on the external wall) and/or on the lymphatic region. The Kaplan-Meier method was used to estimate the rates of disease free survival, loco-regional recurrence-free survival and overall survival. The Pearson Khi2 test was used to analyse the homogeneity between the two groups. The log-rank test was used to evaluate the differences between the two groups A and B.ResultsAfter 76.4 months median follow-up (65.3 months mean follow up), only one patient relapsed to loco-regional breast cancer when the treatment was based on anthracycline. However, 8 patients relapsed to loco-regional breast cancer when the treatment was based on CMF. In the anthracycline group, the disease free survival after 5 years, was 80.4% compared to 76.4% in the CMF group (Log-rank test: p = 0.136). The overall survival after 5 years was 82.5% and 81.1% in the anthracycline and CMF groups respectively (Log-rank test: p = 0.428). The loco-regional free survival at 5 years was equal to 98.6% in group A and 94% in group B (Log-rank test: p = 0,033). The rate of grade II and grade III anaemia was 13.9% and 6.7% in anthracycline group and CMF group respectively (Khi2-test: p = 0.009). The rate of grade II and grade III skin dermatitis toxicity was 4.5% in the group A and 0% in the group B (Khi2-test: p = 0.013).ConclusionFrom the 5 years retrospective investigation we showed similar disease free survival and overall survival in the two concurrent chemo-radiotherapy treatments based on anthracycline and CMF. However in the loco-regional breast cancer the treatment based on anthracycline was significantly better than that of the treatment based on CMF. There was more haematological and skin dermatitis toxicity in the anthracycline group.
