Epidemiological and clinical profile, and survival of patients followed for breast cancer between 2010 and 2015 at the Yaounde General Hospital, Cameroon.

INTRODUCTION: approximately 6000 Cameroonian women died of cancer in 2018, and the breast is the most affected with 2625 new cases. The aim of this study was to establish a pattern of malignant breast tumours in Yaoundé (Cameroon). METHODS: this study was a descriptive and analytical retrospective study of breast cancer between January 2010 and December 2015 in Yaoundé General Hospital (YGH) after the Institutional ethics committee approval. The variables studied were the socio-demographic characteristics, risk factors for breast cancer, types of tumours and type of treatments. The 5-year survival was analyzed by the Kaplan-Meier method. The adjusted hazard ratios and their 95% confidence intervals were calculated to assess the association between studied variables and patient survival through the cox regression using SPSS 23 software. The difference was considered significant at p < 0.05. RESULTS: among the 344 files collected in this study, breast cancer patients were predominantly female (96.64%, n = 288) aged 45.39 ± 13.35 years, with invasive ductal carcinoma (68.03%, n = 270), located in the left breast (52%, n= 147). The average tumour size was ~6.5 ± 0.3 cm and diagnosed in grade II of Scarf Bloom Richardson (SBR) in 60% (n= 150) of cases. The 5-year survival was 43.3%. Factors associated with this poor survival were the religion (aHR 5.05, 95% CI: 1.57 - 16.25; p = 0.007 for animist and aHR 4.2, 95% CI: 1.53 - 11.46; p = 0.005 for protestant), location of the tumour (aHR 6.24, 95% CI: 1.58 - 24.60; p = 0.012), tumor height (aHR 0.21, 95% CI: 0.04 - 1.11; p = 0.011) and the time spent before medical treatment (aHR 5.12, 95% CI: 0.39 - 8.38; p = 0.011). CONCLUSION: the young age, large tumour size and high histological grade in our studied population suggest a weak awareness of women about breast cancer. Action should be taken in early screening to improve the management of breast cancer in Cameroon.

The Pattern of Cervical Cancer according to HIV Status in Yaoundé, Cameroon.

OBJECTIVE: To analyze the epidemiological aspects of invasive cervical cancer according to HIV status. METHODS: This was an historical cohort study from January 2010 to April 2017 in three hospitals at the Yaoundé city Capital, Cameroon, after the National Ethics Committee' approval. We included invasive cervical cancers with documented HIV status. Odds ratios and 95% confidence interval were calculated to assess the association between the different variables and HIV status. Survival was analyzed using the Kaplan-Meier. The level of significance was set up at <5%. RESULTS: Among the overall 213 cervical cancer patients, 56 were HIV+ (24.67%). Factors associated with positive HIV status were age below 40 (OR: 2.03 (1.38-2.67)), celibacy (OR: 2.88 (1.58-4.17)), nonmenopausal status (OR: 2.56 (1.36-3.75)), low parity, primiparity (OR: 2.59 (1.43-3.74)), and for parity with 2-4 children (OR: 2.24 (1.35-3.12)). Concerning the HIV+ patients, tumor was diagnosed late (stages III-IV) (OR: 2.70 (1.43-5.08)), undifferentiated (grade III) (OR: 7.69 (5.80-9.57)), with low median survival (9.83 months vs. 20.10 months). CONCLUSION: HIV is frequent among cervical cancer patients. In the HIV+ patients, the diagnosis was made at the advanced stage, cells were poorly differentiated, and the prognosis was worse.
