Purpose To prospectively compare survival between human immunodeficiency virus (HIV)-infected versus HIV-uninfected cervical cancer patients who initiated curative chemoradiation therapy (CRT) in a limited-resource setting. Methods and Materials Women with locally advanced cervical cancer with or without HIV infection initiating radical CRT in Botswana were enrolled in a prospective, observational, cohort study from July 2013 through January 2015. Results Of 182 women treated for cervical cancer during the study period, 143 women initiating curative CRT were included in the study. Eighty-five percent of the participants (122 of 143) had stage II/III cervical cancer, and 67% (96 of 143) were HIV-infected. All HIV-infected patients were receiving antiretroviral therapy (ART) at the time of curative cervical cancer treatment initiation. We found no difference in toxicities between HIV-infected and HIV-uninfected women. The 2-year overall survival (OS) rates were 65% for HIV-infected women (95% confidence interval [CI] 54%-74%) and 66% for HIV-uninfected women (95% CI 49%-79%) (P = .70). Factors associated with better 2-year OS on multivariate analyses included baseline hemoglobin >10 g/dL (hazard ratio [HR] 0.37, 95% CI 0.19-0.72, P = .003), total radiation dose ≥75 Gy (HR 0.52, 95% CI 0.27-0.97, P = .04), and age <40 years versus 40-59 years (HR 2.17, 95% CI 1.05-4.47, P = .03). Conclusions Human immunodeficiency virus status had no effect on 2-year OS or on acute toxicities in women with well-managed HIV infection who initiated curative CRT in Botswana. In our cohort, we found that baseline hemoglobin levels, total radiation dose, and age were associated with survival, regardless of HIV status.
IntroductionThe number and lifespan of individuals living with HIV have increased significantly with the scale-up of antiretroviral therapy. Furthermore, the incidence of breast cancer in women with HIV is growing, especially in sub-Saharan Africa (SSA). However, the association between HIV infection and breast cancer is not well understood.MethodsA literature search was performed to identify articles published in journals pertaining to breast cancer and HIV, with an emphasis on SSA. Selected US-based studies were also identified for comparison.ResultsAmong the 56 studies reviewed, the largest study examined 314 patients with breast cancer and HIV in the United States. There is no consensus on whether HIV infection acts as a pro-oncogenic or antioncogenic factor in breast cancer, and it may have no relation to breast cancer. A higher incidence of breast cancer is reported in high-income countries than in SSA, although breast cancer in SSA presents at a younger age and at a more advanced stage. Some studies show that patients with breast cancer and HIV experience worse chemotherapy toxicity than do patients without HIV. Data on treatment outcomes are limited. The largest study showed worse treatment outcomes in patients with HIV, compared with their counterparts without HIV.ConclusionHIV infection has not been associated with different clinical presentation of breast cancer. However, some evidence suggests that concurrent diagnosis of HIV with breast cancer is associated with increased therapy-related toxicity and worse outcomes. Systematic prospective studies are needed to establish whether there is a specific association between breast cancer and HIV.
Gynecologic carcinomas, including cervical cancer, present a significant burden on low- and middle-income countries (LMICs). Brachytherapy plays an integral role in the treatment of gynecologic carcinomas, as it is essential for both curative and palliative treatment. However, there are numerous geographic and economic barriers to providing brachytherapy to cancer patients in LMICs. This article examines the role and delivery of brachytherapy in gynecological cancer treatment; brachytherapy capacity in LMICs, including infrastructure, equipment, and human resources considerations; commissioning, training, and clinical implementation of brachytherapy in LMICs; other challenges, and strategies for improvement in brachytherapy delivery in LMICs, including innovation and current and upcoming international initiatives.
PurposeCervical cancer is a major cause of mortality in low- and middle-income countries (LMICs) and the most common cancer diagnosed in women in Botswana. Most women present with locally advanced disease, requiring chemotherapy and radiation. Care co-ordination requires input from a multidisciplinary team (MDT) to deliver appropriate, timely treatment. However, there are limited published examples of MDT implementation in LMICs.MethodsIn May 2015, a weekly MDT clinic for gynecologic cancer care was initiated at Botswana’s national referral facility. The MDT clinic served as a forum for discussion and coordination of patients with gynecologic cancer and consisted of a gynecologist, pathologist, medical oncologist, radiation oncologist, palliative care specialist, and nurse coordinator.ResultsBetween May 2015 and December 2015, 135 patients were seen in the MDT clinic. The mean age of the patients was 49 years. Most (60%) of the patients were HIV positive. The most common diagnosis was cervical cancer (60%), followed by high-grade cervical intraepithelial neoplastic lesions (12%) and vulvar cancer (11%). Only data up to September 2015 were assessed for treatment delays. It was found that only 38% of patients needed more than one visit for care coordination before treatment initiation. Among patients with cervical cancer, the median delay from date of biopsy to start of radiation treatment was 39 days (interquartile range, 34 to 57 days) for patients treated after MDT initiation, compared with 108 days (interquartile range, 71 to 147 days) for patients treated before MDT initiation (P < .001).ConclusionImplementation of MDT clinics in LMICs is feasible and can help reduce delays in treatment initiation, as demonstrated by a gynecologic MDT clinic in Botswana. Streamlining care through MDT clinics can enhance care coordination and improve clinical outcomes. This model can apply to cancer care in other LMICs.
