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.

Intestinal Parasitic Infections in Human Immunodeficiency Virus-Infected and Noninfected Persons in a High Human Immunodeficiency Virus Prevalence Region of Cameroon.

The problem of intestinal parasitic infection in human immunodeficiency virus (HIV)-infected people requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several coinfecting diseases. Studies have addressed this issue in Cameroon, especially in the low HIV prevalence area. The current study was conducted to determine the prevalence of intestinal parasitosis in people living with HIV (PLHIV) in Adamaoua and to identify associated risk factors. Stool and blood specimens from study participants were screened for intestinal parasites and anti-HIV antibodies, respectively. Of 235 participants, 68 (28.9%) were HIV positive, 38 of them on antiretroviral treatment (ART). The overall prevalence of intestinal parasites was 32.3%. Of 68 PLHIV, 32.3% (22/68) were infected with intestinal parasites, compared with 32.3% (54/167) of the HIV-negative patients. Univariate analysis showed no difference between the prevalence of intestinal parasites among PLHIV and HIV-negative patients (P = 0.69). ART was not associated with the prevalence of intestinal parasites. Multivariate analysis showed that the quality of water and the personal hygiene were the major risk factors associated to intestinal parasitosis. The level of education was associated with HIV serostatus: the higher the level of education, the lower the risk of being infected with HIV (P = 0.00). PLHIV and the general population should be screened routinely for intestinal parasites and treated if infected.
