HIV infection is not associated with the initiation of curative treatment in women with cervical cancer in Botswana.

ABSTRACT: BACKGROUND:Cervical cancer is the leading cause of cancer death in Sub-Saharan Africa. The risk of developing cancer is increased for women living with human immunodeficiency virus (HIV) infection. It is unknown which factors predict the initiation of curative chemoradiotherapy (CRT) in resource-limited settings and whether HIV is associated with initiating curative CRT in settings with a high HIV burden. METHODS:All women living with and without HIV infection who were initiating curative and noncurative CRT for locally advanced cervical cancer in Botswana were prospectively enrolled in an observational study. The factors associated with receiving CRT were evaluated in all patients and the subgroup of women living with HIV. RESULTS:Of 519 enrolled women, 284 (55%) initiated CRT with curative intent. The curative cohort included 200 women (70.4%) who were living with HIV and had a median CD4 count of 484.0 cells/?L (interquartile range, 342.0-611.0 cells/?L). In the noncurative cohort, 157 of 235 women (66.8%) were living with HIV and had a median CD4 count of 476.5 cells/?L (interquartile range, 308.0-649.5 cells/?L). HIV status was not associated with initiating curative CRT (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.58-1.56). The factors associated with receiving curative CRT treatment on multivariable analysis in all patients included baseline hemoglobin levels ?10 g/dL (OR, 1.80; 95% CI, 1.18-2.74) and stage I or II versus stage III or IV disease (OR, 3.16; 95% CI, 2.10-4.75). Women aged >61 years were less likely to receive curative treatment (OR, 0.43; 95% CI, 0.24-0.75). Among women who were living with HIV, higher CD4 cell counts were associated with higher rates of CRT initiation. CONCLUSIONS:The initiation of CRT with curative intent does not depend on HIV status. Significant predictors of CRT initiation include baseline hemoglobin level, disease stage, and age.

Project description:ObjectivesVulvar cancer is a rare gynecological malignancy. However, the incidence of human papillomavirus (HPV)-associated vulvar disease is increasing, particularly in low- and middle-income countries. HIV infection is associated with an increased risk of HPV-associated vulvar cancer. We evaluated treatment patterns and survival outcomes in a cohort of vulvar cancer patients in Botswana. The primary objective of this study was to determine overall survival and the impact of treatment modality, stage, and HIV status on overall survival.MethodsWomen with vulvar cancer who presented to oncology care in Botswana from January 2015 through August 2019 were prospectively enrolled in this observational cohort study. Demographics, clinical characteristics, treatment, and survival data were collected. Factors associated with survival including age, HIV status, stage, and treatment were evaluated.ResultsOur cohort included 120 women with vulvar cancer. Median age was 42 (IQR 38-47) years. The majority of patients were living with HIV (89%, n=107) that was well-controlled on antiretroviral treatment. Among women with HIV, 54.2% (n=58) were early stage (FIGO stage I/II). In those without HIV, 46.2% (n=6) were early stage (stage I/II). Of the 95 (79%) patients who received treatment, 20.8% (n=25) received surgery, 67.5% (n=81) received radiation therapy, and 24.2% (n=29) received chemotherapy, either alone or in combination. Median follow-up time of all patients was 24.7 (IQR 14.2-39.1) months and 2- year overall survival for all patients was 74%. Multivariate analysis demonstrated improved survival for those who received surgery (HR 0.26; 95% CI 0.08 to 0.86) and poor survival was associated with advanced stage (HR 2.56; 95% CI 1.30 to 5.02). Survival was not associated with HIV status.ConclusionsThe majority of women with vulvar cancer in Botswana are young and living with HIV infection. Just under half of patients present with advanced stage, which was associated with worse survival. Improved survival was seen for those who received surgery.

Project description:BackgroundThe feasibility of reducing the population-level incidence of human immunodeficiency virus (HIV) infection by increasing community coverage of antiretroviral therapy (ART) and male circumcision is unknown.MethodsWe conducted a pair-matched, community-randomized trial in 30 rural or periurban communities in Botswana from 2013 to 2018. Participants in 15 villages in the intervention group received HIV testing and counseling, linkage to care, ART (started at a higher CD4 count than in standard care), and increased access to male circumcision services. The standard-care group also consisted of 15 villages. Universal ART became available in both groups in mid-2016. We enrolled a random sample of participants from approximately 20% of households in each community and measured the incidence of HIV infection through testing performed approximately once per year. The prespecified primary analysis was a permutation test of HIV incidence ratios. Pair-stratified Cox models were used to calculate 95% confidence intervals.ResultsOf 12,610 enrollees (81% of eligible household members), 29% were HIV-positive. Of the 8974 HIV-negative persons (4487 per group), 95% were retested for HIV infection over a median of 29 months. A total of 57 participants in the intervention group and 90 participants in the standard-care group acquired HIV infection (annualized HIV incidence, 0.59% and 0.92%, respectively). The unadjusted HIV incidence ratio in the intervention group as compared with the standard-care group was 0.69 (P = 0.09) by permutation test (95% confidence interval [CI], 0.46 to 0.90 by pair-stratified Cox model). An end-of-trial survey in six communities (three per group) showed a significantly greater increase in the percentage of HIV-positive participants with an HIV-1 RNA level of 400 copies per milliliter or less in the intervention group (18 percentage points, from 70% to 88%) than in the standard-care group (8 percentage points, from 75% to 83%) (relative risk, 1.12; 95% CI, 1.09 to 1.16). The percentage of men who underwent circumcision increased by 10 percentage points in the intervention group and 2 percentage points in the standard-care group (relative risk, 1.26; 95% CI, 1.17 to 1.35).ConclusionsExpanded HIV testing, linkage to care, and ART coverage were associated with increased population viral suppression.

Project description:BackgroundThe most commonly diagnosed cancers among women are breast and cervical cancers, with cervical cancer being a relatively bigger problem in low and middle income countries (LMICs) than breast cancer.MethodsThe main aim of this study was to asses factors associated with and socioeconomic inequalities in breast and cervical cancer screening among women aged 15-64 years in Botswana. This study is part of the broad study on Chronic Non-Communicable Diseases in Botswana conducted (NCD survey) in 2016. The NCD survey was conducted across 3 cities and towns, 15 urban villages and 15 rural areas of Botswana. The survey collected information on several NCDs and risk factors including cervical and breast cancer screening. The survey adopted a multistage sampling design and a sample of 1178 participants (males and females) aged 15 years and above was selected in both urban and rural areas of Botswana. For this study, a sub-sample of 813 women aged 15-64 years was selected and included in the analysis. The inequality analysis was conducted using decomposition analysis using ADePT software version 6. Logistic regression models were used to show the association between socioeconomic variables and cervical and breast cancer screening using SPSS version 25. All comparisons were considered statistically significant at 5%.ResultsOverall, 6% and 62% of women reported that they were screened for breast and cervical cancer, respectively. Women in the poorest (AOR = 0.16, 95% CI = 0.06-0.45) and poorer (AOR = 0.37, 95% CI = 0.14-0.96) wealth quintiles were less likely to report cervical cancer screening compared to women in the richest wealth quintile. Similarly, for breast cancer, the odds of screening were found to be low among women in the poorest (AOR = 0.39, 95% CI = 0.06-0.68) and the poorer (AOR = 0.45, 95% CI = 0.13-0.81)) wealth quintiles. Concentration indices (CI) showed that cervical (CI = 0.2443) and breast cancer (CI = 0.3975) screening were more concentrated among women with high SES than women with low SES. Wealth status was observed to be the leading contributor to socioeconomic inequality observed for both cervical and breast cancer screening.ConclusionsFindings in this study indicate the need for concerted efforts to address the health care needs of the poor in order to reduce cervical and breast cancer screening inequalities.
