Reversible posterior leukoencephalopathy syndrome following carboplatin and paclitaxel in cervical cancer: Case report.

Posterior reversible leukoencephalopathy is a rare radio-clinical entity that has gained increasing recognition over the last two decades. It is associated with various etiologies: arterial hypertension, autoimmune diseases, chemotherapy, and immunosuppressive drugs. Several cases have already been reported following cancer therapy. Posterior reversible leukoencephalopathy is characterized by capital clinical signs (headache, seizures, confusional syndrome, and visual disorders) and radiological abnormalities (cerebral edema predominantly in the posterior regions). We report the case of a 38-year-old female patient diagnosed with posterior reversible leukoencephalopathy after receiving Carboplatin and Paclitaxel chemotherapy for recurrent cervical cancer, which was revealed by a generalized seizure. Brain magnetic resonance imaging showed T2 Flair hyper signals in the parieto-occipital regions. This complication is rare but is probably underdiagnosed due to a lack of awareness and limited hindsight. Rapid diagnosis is essential to prevent acute neurological complications, which can be life-threatening or functionally crippling regardless of neoplasia.

Patterns of practice survey for cervical cancer brachytherapy in Morocco.

PURPOSE: This study surveyed radiation oncologists in Morocco to explore current practices and perspectives on brachytherapy for cervix cancer. METHODS AND MATERIALS: A 37-question survey was conducted in April 2023 among 165 Moroccan radiation oncologists using Google Forms. RESULTS: Of the 93 respondents, 39% treated over 20 patients in 2022 using 3D image-guided brachytherapy (BT) through the HDR technique; 2D techniques were not reported in the last five years. Intracavitary BT is uniformly applied with a tandem and ovoid applicator. Only 14% utilized interstitial needles for hybrid BT. Iridium-192 was the primary radioactive source (63%), followed by cobalt (37%). Ultrasound-guided 47% of applicator insertions. All used CT scans for planning, but only 6% used MRI fusion due to limited availability. Guidelines for target volume and dose prescription were mostly based on GEC-ESTRO recommendations (74%), followed by Manchester Point A (30.4%) and ABS (11%). Over 90% delineated CTV-HR and CTV-IR; 30% delineated GTV. All marked the bladder and rectum, while 52% marked the sigmoid, 5% the small bowel, and 3% the recto-vaginal point. For dosimetry, 12% used ICRU 89 points, 54% used dose-volume histograms (DVH), and 36% used both. Most reported EQD2cc for OARs for the rectum and bladder, with nine still using ICRU point doses. The most common fractionation schema was 7 Gy in four fractions (60%) and 7 Gy in three fractions (55%). CONCLUSIONS: Brachytherapy remains essential for treating cervical cancer in Morocco. Key areas for improvement include MRI fusion-guided brachytherapy, access to advanced applicators, expanding interstitial techniques, and professional training and national referential.

Metachronous ureteral metastasis of a gastric adenocarcinoma: a case report and review of literature.

BACKGROUND: Ureteral metastasis from gastric cancers are rare and can be a cause of ureteral obstruction. There have been few published case reports in the literature. In this paper, we report an additional case and a review of the literature of all the previous reported cases. CASE PRESENTATION: A 67 years old North African women who was treated four years before for a gastric adenocarcinoma, presented with abdominal pain. Imaging and endoscopy showed a mural stenosis of the left ureter, without any other abnormality. Histopathology confirmed the gastric origin of the metastasis. A palliative chemotherapy was foreseen, but due to the deterioration of the general condition of the patient, she received palliative care. We have also reviewed the literature and reported the previously published cases of ureteral metastasis from gastric cancer. CONCLUSIONS: It is worth recalling that in a context of neoplasia and with the presence of signs of ureteral obstruction, it is important to keep in mind the possibility of a ureteral metastasis.

Epidemiological, Clinicopathological and Prognosis Features of Moroccan Patients with Nasopharyngeal Carcinoma.

PROPOSAL: A distinct epidemiology, etiology, clinical characteristics, and therapeutic outcomes characterize nasopharyngeal carcinoma (NPC) from other head and neck cancers. An actualized analysis of NPC patients' features enables a global view of NPC management. Accordingly, the current study investigated the epidemiological and clinical characteristics of Moroccan patients with NPC, as well as their 4-years survival outcomes and influencing prognostic factors. METHODS: We prospectively analyzed data of 142 histologically confirmed Moroccan patients with NPC between October 2016 and February 2019. Kaplan-Meier and Cox regression analyses were used to assess predictive prognostic factors related to NPC. All analyses were conducted using SPSS version 21 statistical software. RESULTS: In the present study, a net male predominance was found, with a mean age of 44±16.3 years old. Advanced stages of NPC were observed in 64.1% of patients, and 32.4% of patients presented with distant metastasis at diagnosis. The 4-years overall survival, locoregional relapse-free survival, distant metastasis-free survival and progression-free survival were 68.0%, 63.0%, 53.9%, and 39.9%, respectively. Age, N category and distant metastasis were identified as the most important independent prognosis factors for NPC in this cohort (p<0.05). CONCLUSION: In conclusion, NPC affects young adults and is frequently diagnosed at advanced disease stages, impacting therefore negatively patients survival; which is in line with data from endemic areas for NPC. The current study clearly highlights that a greater attention should be directed to improving the management of this aggressive malignancy.

Genetic Polymorphisms in ERCC1 Gene and Their Association with Response to Radiotherapy in Moroccan Patients with Nasopharyngeal Carcinoma.

OBJECTIVE: Nasopharyngeal carcinoma (NPC) is a severe malignant disease. Despite its low frequency, NPC is very common in North African population. Radiotherapy is the standard therapeutic treatment of NPC. However, radioresistance hampers the success of treatment. At the molecular scale, radioresistance is due to genetic variations involved in DNA repair pathways in NPC patients. Several studies reported that single nucleotide polymorphisms (SNPs) in excision repair cross complementing group 1 (ERCC1) could be associated with radioresistance. In this optic, the present study aimed to evaluate the association between DNA repair gene polymorphisms ERCC1 C8092A and ERCC1 C118T and radiotherapy response of patients with NPC. METHODS: A total of 95 patients with confirmed NPC were recruited at the Mohammed VI Center for Cancer Treatment, Casablanca - Morocco between 2016 and 2018. Two single nucleotide polymorphisms in ERCC1 gene were genotyped. Multiple analysis software was used to assess the correlation between these SNPs and radio-therapeutic response. RESULTS: Sequencing of ERCC1 C8092A polymorphism revealed that CC and CA genotypes were found in 51.6% and 45.3% of cases, respectively, whereas the homozygote AA genotype was reported in only 3.1% of cases. For ERCC1 C118T polymorphism, the heterozygote CT genotype was identified in 49.5% of cases. Homozygotes genotypes CC and TT were detected in 17.9% and 32.6% respectively of NPC cases. Of note, no significant association was found between the ERCC1 C8092A polymorphism and response to radiation therapy (p=0.81). Similarly, there was no significant association between the response to radiotherapy and allelic distribution (p=0.56). Likewise, no correlation was observed neither with genotypes (p=0.07) nor with alleles (p=0.09) of ERCC1 C118T polymorphism and response to radiation therapy. CONCLUSION: Our results clearly showed that ERCC1 C8092A and ERCC1 C118T polymorphisms were not associated with response to radiotherapy in Moroccan NPC patients. Large studies are warranted to confirm the role of these SNPs in therapeutic response of NPC patients.

[Which chemotherapy regimen in patients with metastatic phyllodes tumors of the breast? case report]. / Quelle chimiothérapie dans les tumeurs phyllodes métastatiques du sein? rapport de cas.

Phyllodes tumors (PT) of the breast are rare. They can be benign, borderline or malignant. Malignant forms account for 20-30% of PTs, with distant metastases in 10-26% of cases. Chemotherapy is one of the main therapeutic weapons for metastatic phyllodes tumors (MPTs). We here report four cases of MPTs of the breast managed at The Mohammed VI Center For Cancers Treatment in Casablanca from January 2015 to December 2017. The average age of patients ranged from 25 to 45 years. The mode of revelation was represented, in the majority of cases, by the occurrence of a huge breast mass and in all patients the histological diagnosis was based on the examination of mastectomy specimen. Three patients had lung metastases, two had axillary lymph-node metastases, two had bone metastases and only one had liver metastases. All patients received chemotherapy. Doxorubicin monotherapy and doxorubicin-ifosfamide (AI) were used. Only one patient had a very favorable outcome, with radiologic complete response after 3 AI regimens. MPTs of the breast have a poor prognosis. The role of systemic chemotherapy is to be defined, especially since there are no data available on optimal chemotherapy regimen.

Pretreatment [18F]FDG PET/CT and MRI in the prognosis of nasopharyngeal carcinoma.

OBJECTIVE: The present study aimed to assess the prognostic interest of metabolic and anatomic parameters derived from 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography ([18F]FDG PET/CT) and head and neck magnetic resonance imaging (HN-MRI) for better management of nasopharyngeal carcinoma (NPC). METHODS: In this study, pre-treatment [18F]FDG PET/CT and HN-MRI parameters of NPC patients diagnosed between January 2017 and December 2018, were prospectively investigated. Correlation between those parameters and 4-year patient's survival outcomes was evaluated using Kaplan-Meier and Cox-regression analyses. RESULTS: Our results revealed a significant association between pre-treatment nodal-maximum standardized uptake value (N-SUV max) and N categories (p = 0.01), between pre-treatment node-to-tumor SUV ratio (NTR) and both tumor size (p = 0.01) and N categories (p = 0.009), as well as between metabolic tumor volume (MTV) and both tumor size and NPC overall stage (p < 0.000). In multivariate analyses, pre-treatment N-SUV max, NTR and MTV were significant independent predictors of overall survival, distant metastasis-free survival, and progression-free survival (PFS) (p < 0.05). N-SUV max and MTV were also found to be significant independent predictors of loco-regional recurrence-free survival (p < 0.05), whereas HN-MRI detection of skull-base bone invasion was an independent factor associated with worse PFS in NPC (p = 0.03). CONCLUSIONS: The present study highlights N-SUV max, NTR and MTV derived from [18F]FDG PET/CT, and skull-base bone invasion defined by HN-MRI, as promising metabolic and anatomic prognosis biomarkers for NPC.

Prognostic value of Epstein-Barr virus DNA load in nasopharyngeal carcinoma: a meta-analysis.

The present meta-analysis was conducted to evaluate the prognostic value of pre and post-Epstein Barr Virus (EBV) DNA load testing and to assess the clinical benefit of using this molecular approach in the prognosis for a better nasopharyngeal carcinoma (NPC) management. Relevant studies were searched in different database until May 2020. Patient´s outcomes overall survival (OS), disease free survival (DFS), progression-free survival (PFS), distant-metastasis-free survival (DMFS), and local-regional-failure-free survival (LRFS), hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted from selected studies. The association of pre and post-EBV DNA load and survival outcomes was assessed using review manager and the pooled HRs with 95% CIs were calculated. Twenty-six eligible studies were included in this meta-analysis, with a total of 9966 patients. Pooled HRs showed that EBV DNA levels before and after treatment are significantly associated with survival outcomes, with HR (95% CI) of 2.09 [1.74, 2.51] for OS, 1.77 [1.19, 2.62] for DFS, 2.53 [2.18, 2.92] for DMFS, 1.78 [1.45, 2.19] for LRFS and 2.17 [1.91, 2.47] for PFS in pre-EBV DNA, and an HR (95%) of 4.52 [2.44, 8.36], 4.08 [2.38, 6.99], 5.59 [ 3.58, 8.71] and 8.88 [5.29, 14.90] for OS, DFS and PFS and DMFS in post-EBV DNA, respectively. High pre and post-EBV DNA levels were significantly associated with poor NPC patient´s survival outcomes; which clearly confirm the high interest to introduce viral EBV DNA load as a prognostic biomarker for NPC management.

The Dynamic Change in Plasma Epstein-Barr Virus DNA Load over a Long-Term Follow-Up Period Predicts Prognosis in Nasopharyngeal Carcinoma.

The current study was designed to investigate the changes in the circulating Epstein−Barr virus DNA load (EBV DNA) at various time points before and after treatment and its clinical significance in nasopharyngeal carcinoma (NPC). A total of 142 patients with NPC were prospectively enrolled in this study. The plasma EBV DNA concentration was measured before and after treatment using qPCR. The prognostic values of the EBV DNA load were analyzed using the Kaplan−Meier and Cox regression tests. Following multivariate analysis, our data showed that high pre-EBV DNA loads were associated with significantly poorer distant metastasis free survival (DMFS) and progression free survival (PFS); detectable end-EBV DNA loads were associated with significantly worse loco-regional recurrence free survival (LRRFS) and PFS, and the detecTable 6 months-post-EBV DNA loads were associated with significantly poorer overall survival (OS), DMFS and PFS (p < 0.05). Additionally, combining the pre-EBV DNA load and the stage of the disease, our results showed that patients at stage III-IVA with a low pre-EBV DNA load had similar survival rates as patients at stage II with a low or high pre-EBV DNA load, but had better survival rates than those at stage III-IVA with a high pre-EBV DNA load. Taken together, we showed that the change of the EBV DNA load measured at several time points was more valuable than at any single time point for predicting patients' survival for NPC. Furthermore, combining the pre-EBV DNA load and the TNM classification could help to formulate an improved prognostic model for this cancer.

Evaluation of cardiac toxicity of systemic treatments in Moroccan patients followed for localized breast cancer: Prospective observational study of 549 cases.

BACKGROUND: Breast cancer is the most common cancer in women in the world and in Morocco. Anthracyclines and anti-HER2 therapy are major drugs in the therapeutic management of localized breast cancer. The most serious toxicity of these drugs is cardiotoxicity. Our work aims to assess the prevalence of this toxicity in the Moroccan population. PATIENTS AND METHODS: We conducted a prospective longitudinal observational study between January 2017 and June 2018. All our patients were followed in The Cardio-Oncology Unit, 1st unit of its kind in Morocco, created thanks to the collaboration between the Mohammed VI Cancer Treatment Center and The Cardiology Departement of Ibn Rochd University Hospital in Casablanca. Eligible patients (n=549) had Stage I-III localized breast cancer, verified histologically, and a pre-treatment adequate cardiac function with a LVEF = 50%, measured with echocardiography, and received systemic cardiotoxic treatment (anthracycines, anti-her2 drugs). All patients received regular monitoring of cardiac function mainly by echocardiography. Cardiotoxicity was defined as a decrease in LVEF of 10 points and / or <50%. RESULTS: A decrease in LVEF was observed in 8.4% of our patients, with 4% symptomatic heart failure. The baseline average LVEF in the cardiotoxicity group was 63.5% (50-77) versus 60.5% (60-74) in the group without cardiotoxicity. 97.1% of these patients received anthracyclines, 98% received trastuzumab against 97% and 65% in the group without cardiotoxicity respectively. Cardiotoxicity was reversible in 6.4% of patients, permanent discontinuation of cardiotoxic treatment was observed in 2.2%. A statistically significant relationship was found between cardiotoxicity and arterial hypertension (HTA) (p = 0.002), trastuzumab (p = 0.0001) and radiotherapy for left breast cancer (p = 0.023). CONCLUSION: This is one of the first observational studies in Morocco with a large number of patients, which gives us an idea of the cardiotoxicity of systemic treatments in Moroccan localized breast cancer patients. Our results join those of the literature, but are still worrying and invite us, oncologists and cardiologists, to be more vigilant with this toxicity, which influences the oncological and cardiac prognosis of our patients, especially cancer survivors.

Circulating cell-free epstein-barr virus DNA levels and clinical features in Moroccan patients with nasopharyngeal carcinoma.

BACKGROUND: The identification of effective prognosis biomarkers for nasopharyngeal carcinoma (NPC) is crucial to improve treatment and patient outcomes. In the present study, we have attempted to evaluate the correlation between pre-treatment plasmatic Epstein-Barr virus (EBV) DNA load and the conventional prognostic factors in Moroccan patients with NPC. METHODS: The present study was conducted on 121 histologically confirmed NPC patients, recruited from January 2017 to December 2018. Circulating levels of EBV DNA were measured before therapy initiation using real-time quantitative PCR. RESULTS: Overall, undifferentiated non-keratinizingcarcinoma type was the most common histological type (90.1 %), and 61.8 % of patients were diagnosed at an advanced disease stage (IV). Results of pre-treatment plasma EBV load showed that 90.9 % of patients had detectable EBV DNA, with a median plasmatic viral load of 7710 IU/ml. The correlation between pre-treatment EBV DNA load and the conventional prognostic factors showed a significant association with patients' age (p = 0.01), tumor classification (p = 0.01), lymph node status (p = 0.003), metastasis status (p = 0.00) and overall cancer stage (p = 0.01). Unexpectedly, a significant higher level of pre-treatment EBV DNA was also found in plasma of NPC patients with a family history of cancer (p = 0.04). The risk of NPC mortality in patients with high pretreatment EBVDNA levels was significantly higher than that of those with low pre-treatment plasma EBV-DNA levels (p < 0.05). Furthermore, patients with high pre-treatment EBV-DNA levels (≥ 2000, ≥ 4000) had a significant low overall survival (OS) rates (p < 0.05). Interestingly, lymph node involvement, metastasis status and OS were found to be the most important factors influencing the EBV DNA load in NPC patients. CONCLUSIONS: The results of the present study clearly showed a high association between pre-treatment EBV DNA load, the crucial classical prognostic factors (T, N, M and disease stage) of NPC and OS, suggesting that pre-treatment EBV DNA can be a useful prognostic biomarker in clinical decision-making and improving NPC treatment in Morocco.

[A case-control study on dietary risk factors for colorectal cancer in Morocco]. / Facteurs de risque alimentaires du cancer colorectal au Maroc: étude cas témoin.

INTRODUCTION: given its frequency and severity, colorectal cancer is a major public health problem. Diet plays a key role in preventing this type of cancer. The purpose of our study was to determine dietary risk factors for colorectal cancer in our Moroccan context. METHODS: we conducted a case-control study including patients with colorectal cancer compared with controls. The statistical analysis of results was carried out using R software. RESULTS: our study included 225 patients treated for cancer at the Mohammed VI Hospital Center and 225 controls. The average age of our study population at the time of diagnosis was 55.49±14.06 years, including 119 men (52.9%) and 106 women (47.1%) with a sex ratio of 1.12. Associations were found between the highest intakes of red meats, cold meats, sausages and the risk of colorectal cancer (p = 0.0001) with F4 (4-7 times / week) vs F1 (never): OR = 4.4 (1.6-11.9); (p = 0.001), OR = 1.7 (0.5-5.7); (p = 0.003), OR = 5.7 (1.2-27.4)). On the other hand, consumption of fish was associated with a reduced risk of colorectal cancer (p = 0.0001; OR = 0.3 (0.11-0.7)), while consumption of poultry and grilled eggs was not associated with colorectal cancer. We also found that consumption of fresh vegetables and cooked vegetables was low in patients compared to controls (p = 0.0001). Furthermore, a high intake of black coffee was associated with a reduced risk of colorectal cancer (p = 0.0001; F4 vs F1: OR = 0.2 (0.1-0.4)). CONCLUSION: our study highlights that dietary changes can prevent or impede the growth of colorectal cancer. It is essential to promote balanced diet, rich in fish, vegetables, fruits and fibers without exceeding recommended levels of red meat and avoiding cold meats and sausages.

Radiation therapy in mycosis fungoid patient.

Mycosis fungoid (MF) is a non-Hodgkin's T-cell lymphoma determined by primary cutaneous involvement. It is a slow-progressing chronic indolent disease characterized by atypical T-cells with a cerebral nucleus. Management of this disease depends on the stage and is based essentially on the systemic treatment. Radiotherapy intervenes in case of localized or extended tumor, indeed, the radiosensibility of this tumor, like any other hematological affection, makes it possible to obtain a high rate of response. Clinical case: we report the observation of a 46-year-old patient followed since 2012 for mycosis fungoid revealed by a papullo-squamous lesion located at the level of the right lumbar fossa. The diagnosis was confirmed by cutaneous biopsy, showing the presence of T lymphocytes expressing CD2, CD3, CD4, CCR4, CD45RO markers. Initial assessment included a thoraco-abdominal pelvic CT, which was normal, an accelerated sedimentation rate at the 1st hour, a high C reactive protein (CRP), the electrolytic, renal, hepatic status and the hemogram were normal. Patient received 6 courses of chemotherapy according to the COPP protocol with a decrease in the size of the lesion estimated at 40%. A norm fractionated radiation therapy was delivered at the dose of 36Gy. The evolution was marked by a complete remission, maintained after 6 months of the treatment. Mycosis fungoid is a rare disease, whose management must be discussed in a multidisciplinary team. Radiotherapy remains an interesting option for all stages, but has to be validated in largest studies.

[Epidemiological, nutritional and anatomopathological features of patients with colorectal cancer in the greater Casablanca region]. / Aspects épidémiologiques, nutritionnels et anatomopathologiques des cancers colorectaux dans la région du grand Casablanca.

INTRODUCTION: colorectal cancer is a major public health problem. This study aims to analyze the epidemiological, nutritional, clinical and anatomopathological features of patients with colorectal cancer at the University Hospital in Casablanca. METHODS: our case-control study focused on patients assigned to treatment for colorectal cancer in 2015 compared with a control group that didn't have cancer. RESULTS: the average age of our patients was 56.65 years, with a standard deviation of 14.64. The most common histological type of cancer in study patients was Lieberkhünien adenocarcinoma with a proportion of 82%. The analysis of the body mass index showed that 50% of study patients were obese vs 20% of patients in the control group and that 19% of study patients had diabetes vs 8% patients in the control group (p< 0.019). Moreover, the analysis of dietary habits in study patients compared to those of patients in the control group showed that the average frequency of weekly consumption of red meat was higher in study patients than in the control group (4.24 vs 3.26; p = 0.009) and , conversely, for the consumption of fish (0.97 vs 1.76; p = 0.0001). On the other hand, the average consumption of vegetables and fruits was lower in study patients than in the control group (5.00 vs 9.50; p = 0.0001). Concerning the toxic habits of our patients, 32% of study patients were smokers vs. 13% of patients in the control group. CONCLUSION: our results show that awareness about our dietary habits and changes in our living habits could reduce the incidence of colorectal cancer and therefore mortality and morbidity.

[Influence of socio-economic factors and education level on colorectal cancer in the Moroccan population]. / Influence des facteurs socio-économiques et du niveau d'éducation sur le cancer colorectal chez une population marocaine.

INTRODUCTION: Colorectal cancer is a true scourge and a major public health problem. The main purpose of this study was to identify the impact of socio-economic factors and education level on the onset of colorectal cancer and of diagnosis stage in the Moroccan population. METHODS: We conducted a case-control study of patients treated for cancer at the Mohammed VI center from January 2015 to January 2017. We interviewed, on a prospective basis and using a structured and pre-tested questionnaire, 225 patients and 225 eligible and consenting subjects. RESULTS: The average age of patients was 55.49± 14.06 years. In 53% of cases diagnosis was made at early-stage colorectal cancer while in 47% at advanced stage. In addition, a detailed analysis of the studied population according to the socio-economic status (SES), showed a proportion of 25.33% (patients) versus 17.33% (control) in the low SES group, while, equivalent rates (45.33% patients versus 45.33% control) in the middle SES group. In the high SES group, the rate of patients was only 16.89% patients versus 37.34% control (p = 0.0001). Education and SES were strongly correlated with diagnosis stage, with a significant difference. Then 36.44% of illiterate patients were diagnosed in advanced stage versus 5.33% of patients who had completed their secondary education level or university course (p = 0.02). Similarly 20.45% of patients with low SES were diagnosed in late stage versus 5.33% of patients with higher SES (p = 0.03). CONCLUSION: Our results highlight that the risk of developing colorectal cancer is strongly dependent on the education and the socio-economic status of patients. A more thorough investigation is needed to clarify the causes of this inequality.

Aspects épidémiologiques, nutritionnels et anatomopathologiques des cancers colorectaux dans la région du grand Casablanca

Introduction: le cancer colorectal constitue un problème majeur de santé publique. L'objectif de notre étude est d'analyser le profil épidémiologique, nutritionnel, clinique et anatomo-pathologique des cancers colorectaux recrutés au CHU de Casablanca.Méthodes: notre étude cas-témoins a porté sur les patients pris en charge pour un cancer colorectal durant l'année 2015, comparés à des témoins non suivi pour un cancer. Résultats: l'âge moyen des patients était de 56,65 ans avec un écart type de 14,64. Le type histologique le plus fréquent chez nos patients était représenté par l'adénocarcinome Lieberkhünien avec une proportion de 82 %. L'analyse de l'indice de masse corporelle a permis de retrouver une obésité chez 50% des patients contre 20% des témoins et un diabète chez 19% des patients versus 8% des témoins (p < 0,019). Par ailleurs, l'étude du régime alimentaire des patients comparé à celui des témoins semble montrer que la moyenne de la fréquence de consommation hebdomadaire de viandes rouges est plus élevée chez les patients que chez les témoins (4,24 vs 3,26; p = 0,009) et inversement pour la consommation du poissons (0,97 contre 1,76; p = 0,0001). En revanche, la moyenne de consommation des légumes et des fruits est plus faible chez les patients que chez les témoins (5,00 vs 9,50; p = 0,0001). Concernant les habitudes toxiques de nos patients, 32% des patients étaient fumeurs vs 13 % des témoins.Conclusion: nos résultats montrent que la prise de conscience à propos du régime alimentaire et des changements dans nos habitudes de vie pourrait réduire l'incidence du cancer colorectal et par conséquent la mortalité et la morbidité

Adult-type granulosa cell tumor of the testis: report of a case and review of literature.

Granulosa cell tumors is classified into juvenile and adult types and comprise less than 5% of ovarian tumors in women and are much rarer in men which only 45 have been previously reported. We report here a 40-year young man with a left testicular adult type granulosa cell tumor. The tumor measured 5.5X5X4cm; Immunohistochemical stains showed the tumor diffusely positive for inhibin and vimentin. Post operative CT scans shows a lomboaortic lymphnodes treated by four cycles of chemotherapy type BEP (bleomycin, etoposide, cisplatin). The thoraco abdominal CT scans post chemotherapy shows the disappearance of the right testicular nodule and the lomboaortic lymphnodes. 2 years after treatment, the patient is alive and well with no signs of recurrence. Our report highlights one more case of this very rare tumor of the testis, which is quite problematic In terms of prognosis and management, and for this reason seems to have attracted the interest of many researchers recently.

[Brain metastasis from rectal adenocarcinoma: about a case and review of the literature]. / Métastase crânienne d'un adénocarcinome rectal: à propos d'un cas avec revue de la littérature.

The most common primary sites for bone metastases in men are lung, prostate, kidney, thyroid or bladder. Colorectal origin is rare. Few studies have described this type of metastases; the axial skeleton or the pelvis are the most common metastasis locations. Craniofacial location is exceptional. We here report the case of a 38 years old man treated for metastatic rectal cancer metastasized to temporal bone. He initially had undergone surgical procedure for low anterior resection, tumor was classified as pT3N0M0; 24 months after the patient had left exophthalmos revealing a temporal tumoral process. Evolution and context favoured metastasis. In conclusion, this study reporting an exceptional case of craniofacial bone metastasis from multi-metastatic colorectal cancer will enrich the scarce data reported in the literature related to bone metastases from primary colorectal cancer.

[Breast cancer in men: about 40 cases and literature review]. / Cancer du sein chez l'homme: à propos de 40 cas et revue de la littérature.

Breast cancer in men is rare, accounting for approximately 1% of all breast cancers and less than 1% of all neoplasias in men. This study aimed to highlight the clinical histological, prognostic and therapeutic features of this rare tumor in order to contribute to improve the management of these patients. We conducted retrospective study of 40 patients whose data were collected at the Mohammed VI Center for Cancers Treatment in Casablanca from January 2000 to December 2012. The average age was 62 years, the mean consultation time was 12 months, self-exam of a peri-areolar nodul was the main reason for consultation in 90% of cases. Infiltrating ductal carcinoma was the predominant histological type in 90% of cases. Multimodal treatment was based on mastectomy followed by adjuvant therapy including chemotherapy, radiation therapy and/or hormonal therapy, depending on tumor stage and its histological features. The mean follow-up time was 38 months, patient's evolution was characterized by complete remission in 16 patients (40%), local recurrence in 3 patients (7.5%) and metastatic recurrence in 5 patients (12.5%). Metastases mainly occurred in the bones (62%), followed by the lungs and the liver. 10 patients (25%) died. Breast cancer in men is similar to breast cancer in women. However it has its own peculiarities, hence the importance of conducting broader prospective randomised studies in order to improve the treatment and the prognosis of this disease with a high psychosocial impact.

[A case of angiosarcoma of the outer ear]. / Un cas d'angiosarcome de l'oreille externe.

Angiosarcoma of the ear is a very rare and locally aggressive malignant tumor. It accounts for 4-5% of cutaneous sarcomas and less than 1% of all sarcomas. Our study aims to describe and discuss diagnostic and therapeutic modalities of this malignancy. We report the clinical case of a 31 year old patient with bulging mass of the pavilion of the left ear. CT scan was in favor of tumor of the pavilion of the ear invading ipsilateral parotid. Histological diagnosis was in favor of angiosarcoma. The treatment consisted of complete surgical resection followed by adjuvant radiotherapy. She is in complete remission with a follow-up period of 1 year.
