What could be the reasons of late diagnosis of breast cancer in Tunisia?

INTRODUCTION: Breast cancer is often diagnosed at a late stage in Tunisia with long delay in time to consultation and to diagnosis. The aim of the study was to identify explanatory factors to delayed diagnosis. METHODS: A case control analytical was performed from January 2013 to December 2014 in the department of Medical Oncology in FarhatHachedUniveristy Hospital.Patients with the diagnosis of ductal breast carcinoma were included in the study.Characteristics of a first group of 200 women with locally advanced or metastatic breast cancer (G1)were compared to a second group of 200 patients with early stage (G2). RESULTS: Median delay in consultation and mean tumor size were significantly more important in group G1 (p<0,001).A low level of schooling, a rural origin, poor socio-economic conditions and no encouragement by the patient relatives do not allow an early diagnosis.Misinterpretation of clinical breast signs was the only explanatory factor related to the system. In multivariate study, a low level of schooling(adjusted OR=2.72; CI 95% [1,65-4,49]), no encouragement by the patient's relatives(adjusted OR=7.86; CI 95% [4,24-14,57])and more than three dependants(adjusted OR=2.49; CI 95% [1,58-3,93]) were the independent factors that could explain the delay in diagnosis. CONCLUSION: Our study confirm the inverse relationship between socio-economic and scholar level and disease stage. Health education campaigns particularly among women with a low schooling level and of rural origin could reduce time for consultation. Promoting continuing medical education could avoid diagnostic errors.

Small cell carcinoma of the ovary of hypercalcemic type: a case report.

Introduction. The small cell carcinoma of hypercalcemic type of ovary is a very aggressive tumor. It is associated with two-thirds of cases with hypercalcemia most often asymptomatic. It occurs mostly for young women. The treatment combines surgery, chemotherapy, and radiotherapy. Case Presentation. We report a case of small cell carcinoma of the ovary hypercalcemic type in a young Tunisian woman aged 25 years after a severe abdominal pain syndrome and a large ovarian mass discovered in scanner; a laparotomy was performed by radical surgery. The pathological examination of the specimen confirmed the diagnosis. The radiological assessment performed after surgery showed a continuing evolution. Palliative chemotherapy was established, and the patient had died two months after diagnosis. Conclusion. The hypercalcemic small cell carcinoma of the ovary is a rare disease of poor prognosis.

[Primary digestive tract lymphoma in central region of Tunisia: anatomoclinical study and therapeutic results about 153 cases]. / Les lymphomes primitifs du tube digestif (LPTD) dans le centre tunisien: étude anatomoclinique et résultats thérapeutiques à propos de 153 cas.

Primary gastro-intestinal lymphoma (PGIL) is the most common type of extra-nodal non Hodgkin's lymphoma. Their clinical and histological presentations are heterogeneous depending on the site of the lesion. There is no consensus regarding the role of surgery and chemotherapy in the therapeutic approach. In our country epidemiology of the disease is unknown with IPSID being the most frequent type. We report anatomo-clinical features and prognostic factors of PGIL and compare intestinal to gastric forms in our region. This is a retrospective study of 153 cases of PGIL in adults diagnosed and treated in the department of medical oncology in Farhat Hached Hospital between 1994 and 2006. The median age was 52 years and the sex-ratio 2.1. Tumor sites were gastric (67%), intestinal (26%) and gastrointestinal (7%). Abdominal pain (87%) followed by vomiting and diarrhoea (37 and 15%) were the most common symptoms. Performance status (PS) < 2 was seen in 80% of patients, high grade lymphoma in 70.5% of cases and B phenotype was noted in 85%. MALT lymphoma accounts for 50% of cases, and IPSID for only 5% of PGIL. About 47.5% of cases were stage IE, 138 patients had chemotherapy with an objective response rate of 77%. Only 46% of patients had surgery (14 for surgical complication, 6 for residual tumor after chemotherapy and 22 to have histological diagnosis). The five-year overall survival (OS) was 62%. In high grade lymphoma patients favorable prognostic factors for OS included young age < or = 60 years, PS < 2, normal serum LDH, hemoglobin > 12 g/dL, B phenotype, localised stage (IE-IIE1), anthracycline-based chemotherapy regimen, achieving complete or partial response to induction chemotherapy and no relapse. In multivariate study only relapse and PS were significant prognostic factors for OS. In low-grade lymphoma patients, none of these factors had a significant correlation with OS: age < or = 60 years, PS < 2, stage (IE-IIE1), response to induction chemotherapy, relapse. Compared to gastric lymphomas, intestinal cases occurred at a younger age, frequently with diarrhoea, weight loss, and occlusion. They are more often high-grade, T phenotype and have locally advanced stage (IIE); surgery is more common in this group. We conclude that stomach is the main site of PGIL in our region, intestinal lymphoma is less frequent and IPSID has become rare. Recent progress in chemotherapy has allowed good therapeutic results with a conservative approach. Surgery may be performed in case of emergency or for residual lesions after medical treatment.

[Prognostic factors and survival of metastatic colorectal cancer in the Sousse University Hospital (Tunisia): comparative study of two treatment period of 200 patients]. / Facteurs pronostiques et survie des cancers colorectaux métastatiques au CHU de Sousse (Tunisie): etude comparative de deux périodes de traitement de 200 patients.

UNLABELLED: Between 1994 and 2005, 200 patients with metastatic colo-rectal cancers were treated in the Sousse CHU (Tunisia), we analysed two groups of patients, the group 1 was treated in the period after 1999 (N = 64), the group 2 was treated in the period between 1999 and 2005 (N = 136). PATIENTS AND METHODS: Mean age of the patients was 50 years, localisation of metastases was liver in 67.3% of cases, 23% of patients had multiple metastases, 44% of cases developed metastases after a median period of 11.4 months. All patients had received first line of chemotherapy, the regimen of chemotherapy was in the group 1, Fufol in the majority of cases (76%), the regimen of chemotherapy was in the group 2, simplified LV5FU2 associated to irinotecan in the majority of cases (83%), 28% of all patients received second line of chemotherapy. RESULTS: The median survival was 13.8 months in the group 1 and 19 months in the group 2. Overall survival rates at 2 years were 35% and 42% (p = 0.02) in group 1 and 2, respectively. Prognostic factors for a better survival using univariate analysis were: normal ACE (P < 0.01), normal liver analysis (P < 0.001), response after 3 cycles of chemotherapy (P < 0.0005), resection of liver metastases (P < 0.05). The multivariate analysis (cox model) revealed only one independent factor: radiologic response after 3 cycles of chemotherapy (P < 0.03). CONCLUSION: The prognostic of patients with metastatic disease is poor, although palliative chemotherapy after the recent advances and the use of new drugs have been shown to be able to prolong survival and to improve the quality of life over best supportive care. This study report amelioration of prognostic and survival of metastatic colorectal cancers in Tunisia.

[Chemotherapy-induced febrile neutropenia: about 200 episodes. Clinical, microbiological and therapeutic characteristics]. / Les neutropénies fébriles chimio-induites : à propos de 200 épisodes. Profil clinique, microbiologique et thérapeutique.

Cytotoxic chemotherapy suppresses the haematopoietic system, febrile neutropenia is the most serious haematological toxicity associated with the risk of life-threatening infections. We present a retrospective study of 200 episodes of febrile neutropenia in 128 patients treated in department of medical oncology. The aim of this study was to determinate the clinical, therapeutic and evolutive characteristics in patients treated essentially for solid tumors. Among these patients, 72% of them have at least two episodes, the median age was 34 years with extremes six and 75 years. It has been noticed that 26.3% of patients have diabetes, the dominate neoplasm was solid tumors in 79.7%, 65% of patients have received preventive colony-stimulating factors, 83% have received preventive buccal disinfection with antifungic. The median duration of hospitalisation was 12 days, the median delay of febrile neutropenia was 10 days with extremes two and 31 days, median duration of febrile neutropenia was 5.45 days with extremes one and 24 days. Among these cases, 9.45% of them have nadir zero, 68% of patients have clinical documented infections, ORL in 47% of cases. According to the study, 12% of cases have documented microbiological fever, the sites was urinary in 33% of cases, blood in 33% of cases, derm in 30% of cases. The microbe was staphylococcus negative coagulase in 37.5% essentially in blood and derm, the Escherichia coli in 20.8% essentially in urinary and blood. First line antibiotherapy was cefotaxim associated with amikacine in 93.5%, second line antibiotherapy was association of imipenam and amikacine in 82% of cases. Among these cases,7% of them have received anti-staphylococcus, and antifungic treatment in 50% of cases. The thermic defervescence was obtained in median delay of 2.8 days. We have noted nine deaths (22% of cases). Recent surveys indicate that neutropenia remains a prevalent problem associated with substantial morbidity, mortality and costs. The colony-stimulating have used effectively in a variety of clinical settings to prevent or treat febrile neutropenia and to assist patients receiving dose-intensive chemotherapy.
