RESUMO

The majority of deaths from cervical cancer occur in low- and middle- income countries (LMICs). The standard of care for early-stage cervical cancer (FIGO 2018 IA2-IB1) is radical hysterectomy, a procedure performed by trained gynecologic oncologists. However, the lack of gynecologic oncologists in LMICs has required exploration into other methods of treatment for early-stage cervical cancer. A potential course of treatment for early-stage cervical cancer is neoadjuvant chemotherapy followed by simple hysterectomy and pelvic lymph node sampling, which can be performed by a general gynecologist. We gathered data for 8 women who underwent this method of treatment and found that cause-specific survival was 100% over a 3.5-year median follow-up. These findings support the exploration for this method of treatment for early-stage cervical cancer in LMICs, which would improve access to treatment for these women and hopefully reduce the high burden of cervical cancer related deaths in LMICs.

RESUMO

Maternal rectovaginal colonization is the major risk factor for early-onset neonatal sepsis due to Group B Streptococcus (GBS), a major cause of early life morbidity and mortality. Transmission generally occurs perinatally from colonized mothers to infants. Vaccines targeting a subset of GBS serotypes are under development, but GBS epidemiology remains poorly understood in many African nations. We performed a cross-sectional study of GBS colonization among pregnant women at two sites in Botswana, a country with minimal prior GBS carriage data. We found a rectovaginal colonization rate of 19%, comparable with studies in other regions; however, we also noted a striking predominance of serotype V (> 45% of strains). Although further studies are required to delineate the burden of invasive GBS disease in Botswana and the generalizability of type V epidemiology, these data provide a useful baseline for understanding the potential local impact of GBS prevention strategies, including vaccines.

RESUMO

OBJECTIVES: Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) are curable, mostly asymptomatic, STIs that cause adverse maternal and perinatal outcomes. Most countries do not test for those infections during antenatal care. We implemented a CT, NG and TV testing and treatment programme in an antenatal clinic in Gaborone, Botswana. METHODS: We conducted a prospective study in the antenatal clinic at Princess Marina Hospital in Gaborone, Botswana. We offered pregnant women who were 18 years or older and less than 35 weeks of gestation, CT, NG and TV testing using self-collected vaginal swabs. Testing was conducted using a GeneXpert® CT/NG and TV system. Those who tested positive were given directly observed antibiotic therapy and asked to return for a test of cure. We determined the prevalence of infections, uptake of treatment and proportion cured. The relationships between positive STI test and participant characteristics were assessed. RESULTS: We enrolled 400 pregnant women. Fifty-four (13.5%) tested positive for CT, NG and/or TV: 31 (8%) for CT, 5 (1.3%) for NG and 21 (5%) for TV. Among those who tested positive, 74% (40) received same-day, in person results and treatment. Among those who received delayed results (6), 67% (4) were treated. Statistical comparisons showed that being unmarried and HIV infected were positively association CT, NG and/or TV infection. Self-reported STI symptoms were not associated with CT, NG and/or TV infection. CONCLUSION: The prevalence of CT, NG and/or TV was high, particularly among women with HIV infection. Among women with CT, NG and/or TV infection, those who received same-day results were more likely to be treated than those who received delayed results. More research is needed on the costs and benefits of integrating highly sensitive and specific STI testing into antenatal care in Southern Africa.

RESUMO

PURPOSE: Cervical 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. METHODS: In 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. RESULTS: Between 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). CONCLUSION: Implementation 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.

RESUMO

Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are sexually transmitted infections (STIs) associated with adverse birth outcomes. Untreated partners contribute to high rates of STI reinfection; thus, partner notification and treatment remain important components of STI care and control. A prospective cohort study was conducted among 300 pregnant women presenting to the antenatal clinic at Princess Marina Hospital in Gaborone, Botswana who enrolled in an STI screening study. Following informed consent and sample collection for CT/NG/TV testing, participants were asked if they were willing to disclose their STI result and to deliver medications to their partner(s). Those who tested positive were asked at a follow-up appointment if they notified their partners. Among the 300 participants, 294 (98%) said they would be willing to tell their partner(s) about their test results if they tested positive, and 284 (95%) said they would be willing to give their partner(s) medication if the option was available. Of those who tested positive and returned for a test of cure, 27 of 32 (84%) reported that they told their partner about the results, and 20 of 32 (63%) reported that their partner received treatment. Almost all pregnant women reported willingness to tell their partner the STI test result and give their partner medications. At test of cure, most women reported informing their partner, although actual treatment receipt was lower. Our findings suggest that pregnant women are willing to utilize patient-based partner notification, but actual partner treatment might be lower than intended.

RESUMO

INTRODUCTION: Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are curable sexually transmitted infections (STIs) that can cause adverse maternal and birth outcomes. Most countries do not conduct routine testing during antenatal care. We present data on the acceptability and feasibility of testing and treating pregnant women for STIs in an antenatal clinic in Gaborone, Botswana. MATERIALS AND METHODS: We offered CT, NG, and TV testing using self-collected vaginal swabs to eligible pregnant women. Participants received same-day test results. Those who tested positive were given treatment. RESULTS: Among the 225 women who were eligible and recruited, 200 (89%) agreed to participate. The median age of our study sample was 30 years; most were unmarried (77%), with a median gestational age of 27 weeks and a 23% HIV prevalence. All participants received their results with at least 72% (n = 143) on the same day. Thirty participants (15%) tested positive for an STI, all were treated, and 24 (80%) were treated on the same day. CONCLUSION: The acceptability of STI testing was high, and the intervention was feasible. This study provides support for continued research into STI prevalence, cost-effectiveness, and the association of STIs with adverse maternal and infant outcomes.

RESUMO

Botswana has a high burden of cervical cancer due to a limited screening program and high HIV prevalence. About 60% of the cervical cancer patients are HIV positive; most present with advanced cervical disease. Through initiatives by the Botswana Ministry of Health and various strategic partnerships, strides have been made in treatment of pre-invasive and invasive cancer. The See and Treat program for cervical cancer is expanding throughout the country. Starting in 2015, school-going girls will be vaccinated against HPV. In regards to treatment of invasive cancer, a multidisciplinary clinic has been initiated at the main oncology hospital to streamline care. However, challenges remain such as delays in treatment, lack of trained human personnel, limited follow-up care, and little patient education. Despite improvements in the care of pre-invasive and invasive cervical cancer patients, for declines in cervical cancer-related morbidity and mortality to be achieved, Botswana needs to continue to invest in decreasing the burden of disease and improving patient outcomes of patients with cervical cancer.
