Prostate cancer (CaP) represents a significant cause of cancer-related mortality on a global scale. Low- and middle-income countries (LMIC), particularly those in sub-Saharan Africa (SSA), face a disproportionate burden of this disease. Underlying genetic factors as well as barriers to early diagnosis and treatment lead to overall worse outcomes for CaP patients in SSA compared with the United States (U.

Article Synopsis
  • Cervical cancer continues to be a significant public health challenge in Botswana, particularly among indigenous and marginalized groups, despite the introduction of a quadrivalent HPV vaccine and screening initiatives.
  • A study involving 171 non-HPV vaccinated women aged 21 and older assessed the prevalence of high-risk HPV genotypes and cervical lesions through interviews, Pap smears, and HPV testing.
  • The results revealed that 31% of participants were HIV positive, and 13.5% exhibited cervical dysplasia, with various atypical cell types identified, although no cases of high-grade lesions or cervical cancer were found.

Purpose: The growing cancer burden in Botswana has been linked to aging, lifestyle factors, and high HIV infection prevalence. The government has designated four geographically distributed hospitals as public oncology centers (POCs). A needs assessment was undertaken to ascertain the characteristics of cancer care at these centers.

Introduction: Cervical cancer, a malignancy caused by infection with oncogenic human papillomavirus, disproportionally affects women from low resource settings. Persistence of human papillomavirus infection may mediate an association between tobacco use and cervical cancer. In limited resource settings, women from indigenous communities are often marginalized and do not benefit from evidence-based interventions to prevent tobacco use or cervical cancer due to the limited reach of mainstream healthcare services to these communities.

Background: New models of care are required to support women with breast cancer due to rising incidence and mortality in sub-Saharan Africa (SSA). This study gives voice to the experiences of advanced-stage breast cancer patients in the Botswana healthcare system, to guide improved service provision and the potential utility of patient navigator (PN) programs.

Methods: focus group discussions (FGD) were conducted with advanced-stage breast cancer patients recruited from the oncology ward of the public Princess Marina Hospital located in Gaborone, Botswana.

Cancer incidence is rising across sub-Saharan Africa (SSA), and is often characterized by late-stage presentation, early age of onset and poor survival. While a number of oncology drugs are now improving the length and quality of life for cancer patients in high-income countries, significant disparities in access to a range of oncology therapeutics exist for SSA. A number of challenges to drug access such as drug costs, lack of infrastructure and trained personnel must be urgently addressed to advance oncology therapies for SSA.

Article Synopsis
  • * The World Health Organization (WHO) started a plan in 2018 to help eliminate cervical cancer by providing vaccines, screening, and treatment.
  • * There are still big challenges in helping women with HIV, including the need for better vaccines and addressing issues like poverty and discrimination.

Breast cancer is the most frequent cause of cancer death in low- and middle-income countries, in particular among sub-Saharan African women, where response to available anticancer treatment therapy is often limited by the recurrent breast tumours and metastasis, ultimately resulting in decreased overall survival rate. This can also be attributed to African genomes that contain more variation than those from other parts of the world. The purpose of this review is to summarize published evidence on pharmacogenetic and pharmacokinetic aspects related to specific available treatments and the known genetic variabilities associated with metabolism and/or transport of breast cancer drugs, and treatment outcomes when possible.
