Cervical cancer management in a low resource setting: A 10-year review in a tertiary care hospital in Kenya.

Background: Cervical cancer is one of the leading causes of cancer mortality among women in Kenya due to late presentations, poor access to health care, and limited resources. Across many low- and middle-income countries infrastructure and human resources for cervical cancer management are currently insufficient to meet the high population needs therefore patients are not able to get appropriate treatment. Objective: This study aimed to describe the clinicopathological characteristics and the treatment profiles of cervical cancer cases seen at Moi Teaching and Referral Hospital (MTRH). Methods: This was a retrospective cross-sectional study conducted at MTRH involving the review of the electronic database and medical charts of 1541 patients with a histologically confirmed diagnosis of cervical cancer between January 2012 and December 2021. Results: Of the 1541 cases analyzed, 91% were squamous cell carcinomas, 8% were adenocarcinomas, and 1% were other histological types. Thirty-eight percent of the patients were HIV infected and less than 30% of the women had health insurance. A majority (75%) of the patients presented with advanced-stage disease (stage IIB-IV). Only 13.9% received chemoradiotherapy with curative intent; of which 33.8% received suboptimal treatment. Of the 13% who received surgical treatment, 45.3% required adjuvant therapy, of which only 27.5% received treatment. Over 40% of the women were lost to follow-up. Conclusion: Most of the patients with cervical cancer in Kenya present at advanced stages with only a third receiving the necessary treatment while the majority receive only palliative treatment or supportive care.

Human Immunodeficiency Virus Type 1 RNA Genital Tract Shedding After Cryotherapy for Cervical Intraepithelial Neoplasia in Western Kenya.

This prospective study of 39 women living with human immunodeficiency virus (HIV) on antiretroviral therapy in Western Kenya aimed to quantify genital tract HIV-1 RNA (GT-HIV RNA) shedding before and after cryotherapy for cervical intraepithelial neoplasia. Most GT-HIV RNA shedding was detected precryotherapy, suggesting that cryotherapy was not the primary cause of shedding.

Epidemiological profile and clinico-pathological features of pediatric gynecological cancers at Moi Teaching & Referral Hospital, Kenya.

Background: The main pediatric (0-18 years) gynecologic cancers include stromal carcinomas (juvenile granulosa cell tumors and Sertoli-Leydig cell tumors), genital rhabdomyosarcomas and ovarian germ cell. Outcomes depend on time of diagnosis, stage, tumor type and treatment which can have long-term effects on the reproductive career of these patients. This study seeks to analyze the trends in clinical-pathologic presentation, treatment and outcomes in the cases seen at our facility. This is the first paper identifying these cancers published from sub-Saharan Africa. Method: Retrospective review of clinico-pathologic profiles and treatment outcomes of pediatric gynecologic oncology patients managed at MTRH between 2010 and 2020. Data was abstracted from gynecologic oncology database and medical charts. Results: Records of 40 patients were analyzed. Most, (92.5%, 37/40) of the patients were between 10 and 18 years. Ovarian germ cell tumors were the leading histological diagnosis in 72.5% (29/40) of the patients; with dysgerminomas being the commonest subtype seen in 12 of the 37 patients (32.4%). The patients received platinum-based chemotherapy in 70% of cases (28/40). There were 14 deaths among the 40 patients (35%). Conclusion: Surgery remains the main stay of treatment and fertility-sparing surgery with or without adjuvant platinum-based chemotherapy are the standard of care with excellent prognosis following early detection and treatment initiation. LMICs face several challenges in access to quality care and that affects survival of these patients. Due to its commonality, ovarian germ cell cancers warrant a high index of suspicion amongst primary care providers attending to adnexal masses in this age group.

Focused Training of Community Health Volunteers on Cervical Cancer in Rural Kisumu.

The cancer disease burden is higher in the low- and middle-income countries like Kenya where uptake of screening services is low. Community health volunteers (CHVs) have been shown to be effective in improving uptake of health services and could also be used in cervical cancer screening. However, they still have inadequate knowledge hindering effective public education. The aim of this study is to determine the effect of focused training of the CHVs on their knowledge on cervical cancer and screening uptake among women of reproductive age. This was a quasi-experimental study in rural sub-counties of Nyando and Nyakach. Nyando was the intervention arm with 186 CHVs and Nyakach the control with 239 CHVs. Participants' knowledge on cervical cancer was assessed using a self-administered questionnaire. CHVs in the intervention arm were trained about cervical cancer and screening. Knowledge was re-assessed following a 6-month public education period. The focused training improved the CHVs' knowledge on cervical cancer to 60.9% compared to 13.4% in the control arm (p = 0.004) at the end-line. The knowledge was dependent on the level of education (χ2 = 34.41, p = 0.045), religion (χ2 = 25.85, p = 0.007), and occupation (χ2 = 95.04, p < 0.0001). Screening uptake was significantly associated with knowledge of risk factors (p = 0.019) and sign and symptoms (p = 0.017). Screening uptake improved in the intervention arm while declined in the control arm. The training significantly improved the CHVs' knowledge on cervical cancer and uptake of screening services in the intervention area, Kisumu County, Kenya, and should be continuous.

Low-dose oxytocin as an adjunct to Foley catheter for cervical ripening in nulliparous women at MTRH, Eldoret, Kenya: A randomized controlled trial.

OBJECTIVE: To investigate whether the addition of oxytocin to cervical ripening with a Foley catheter (FC) among nulliparous women shortens the time to delivery. METHODS: In this double-blinded randomized trial conducted at Moi Teaching and Referral Hospital, 220 women were randomly assigned to FC plus low-dose oxytocin as treatment or FC plus placebo as controls in a 1:1 ratio. A modified intention-to-treat analysis was performed using SPSS v24. The protocol was approved by the institutional ethics committee and registered at www.ctr.pharmacyboardkenya.org; ECCT/19/08/02. RESULTS: Baseline characteristics were similar. Time to delivery was shorter by 3 h in the treatment group compared with the controls (25.4 versus 28.4 h, P = 0.002). The treatment group had a 22% increased likelihood of delivery within 24 h compared with the controls (53.3% versus 43.1%, relative risk [RR] 1.22, 95% confidence interval [CI] 0.938-1.579, P = 0.135). The controls were however twice more likely to deliver by cesarean section than the treatment group (39% versus 21%, RR 2.32, 95% CI 1.16-2.73, P = 0.006). There were no significant differences in neonatal or other maternal outcomes. CONCLUSION: FC with adjunctive oxytocin for cervical ripening in nulliparous women results in a shorter time to delivery and reduced cesarean deliveries when compared with FC alone.

Detection of types of HPV among HIV-infected and HIV-uninfected Kenyan women undergoing cryotherapy or loop electrosurgical excision procedure.

OBJECTIVE: To assess the baseline types of HPV infection among HIV-positive and HIV-negative women in western Kenya undergoing cryotherapy or loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia. METHODS: A prospective observational study was conducted of baseline HPV characteristics of women undergoing visual inspection with acetic acid (VIA) and cryotherapy or LEEP. After a positive VIA in HIV-positive and HIV-negative women, data on demographics, CD4 count, and use of antiretroviral therapy and a cervical swab were collected. HPV typing was performed using the Roche Linear Array. RESULTS: Of 175 participants, 86 (49.1%) were HIV-positive and had a higher prevalence of low-risk HPV types (odds ratio [OR] 5.28, P=0.005) compared with HIV-negative women. The most common high-risk (HR)-HPV types in HIV-positive women were HPV 16 (13.9%) and HPV 18 (11.1%). HIV-positive women requiring LEEP were more likely to have HR-HPV types (OR 6.67, P=0.012) and to be infected with multiple HR-HPV types (OR 7.79, P=0.024) compared to those undergoing cryotherapy. CONCLUSION: HIV-positive women requiring LEEP versus cryotherapy had a higher prevalence of any HR-HPV type and multiple HR-HPV types. There were no such differences in HPV types identified among HIV-negative women.

Loop Electrosurgical Excision Procedure Treats Cervical Intraepithelial Neoplasia 2/3 Among HIV- and HIV+ Women in Kenya.

OBJECTIVE: The aim of the study was to compare loop electrosurgical excision procedure (LEEP) as treatment for cervical intraepithelial neoplasia (CIN) 2/3 in HIV- versus HIV+ women. MATERIALS AND METHODS: Seventy-five HIV- and 75 HIV+ women at 6 months or more after LEEP for CIN 2/3 were enrolled between September 2013 and November 2014 in this prospective cohort study at the cervical cancer screening clinic in Eldoret, Kenya. Visual inspection with acetic acid (VIA), followed by cervical cytology with conventional cytology, was performed on all women. Women with positive VIA or abnormal cervical cytology underwent colposcopy/biopsy. Lesion progression, persistence, and regression were assessed to quantify the efficacy of LEEP. RESULTS: Post-loop electrosurgical excision procedure screening test showed both a negative VIA and normal cervical cytology in 64 (85%) of HIV- and 57 (77%) HIV+ women (risk difference = 8.3%, CI = -4.2% to 21%, p = .20). Eleven (15%) HIV- and 17 (23%) HIV+ (p = .20) women had positive VIA, abnormal cervical cytology, or both and were referred for colposcopy/biopsy. Twenty-one (8 HIV-, 13 HIV+) women were biopsied. Of the 8 HIV- women, 4 (50%) had CIN lesions that regressed, 3 (38.0%) persisted, and 1 (12%) progressed to invasive cancer after LEEP. Of the 13 HIV+ women, 6 (46%) had CIN lesions that regressed, 7 (54%) had CIN lesions that persisted, and no HIV+ women had CIN lesions that progressed after LEEP. There was no difference in estimated efficacies of LEEP for HIV- and HIV+ women (92.7% versus 89.4%, risk difference = 3.3%, CI = -4.8% to 15.3%, p = .85). CONCLUSIONS: Loop electrosurgical excision procedure for CIN 2/3 is effective treatment for HIV- and HIV+ women in low-resource settings. Future efforts should improve follow-up after treatment.

Knowledge of Cervical Cancer and Acceptability of Prevention Strategies Among Human Papillomavirus-Vaccinated and Human Papillomavirus-Unvaccinated Adolescent Women in Eldoret, Kenya.

Cervical cancer is a critical public health concern in sub-Saharan Africa. Adolescents are key targets in primary prevention strategies. Following a human papillomavirus (HPV) vaccination initiative (Gardasil) in Eldoret, Kenya, the knowledge and source of information of cervical cancer and acceptance of prevention strategies among vaccinated and unvaccinated adolescents were evaluated. A cross-sectional comparative study enrolled 60 vaccinated and 120 unvaccinated adolescent women. Institutional ethical approval was obtained and signed consent was obtained from the parents. Data collection was performed using interviewer-administered questionnaires derived from factual statements based on information from print material used for community sensitization on cervical cancer. The median age of the participants was 14.0 years (interquartile range [IQR] = 13.0-15.0). Of 60 vaccinated adolescents, 56 (93.3%) had heard of the HPV vaccine compared with 6 (5%) of unvaccinated participants (p < 0.001). Of 60 vaccinated participants, 58 (96.7%) had heard of cervical cancer compared with 61 (50.8%) unvaccinated participants (p < 0.001). Both cohorts identified the school as the main source of information for cervical cancer. The two groups also showed similarity in their selection of cervical cancer prevention strategies acceptable to them such as delaying sexual debut, limiting number of sexual partners, and use of condoms for protection against sexually transmitted infections. Of 120 unvaccinated participants, 63.7% expressed willingness to be vaccinated. Exposure to the HPV vaccine was associated with a higher knowledge of cervical cancer. The adolescents predominantly rely on the school for health information. Both cohorts of adolescents showed remarkable acceptability for cervical cancer prevention strategies.

Use of Palliative Cisplatinum for Advanced Cervical Cancer in a Resource-Poor Setting: A Case Series From Kenya.

PURPOSE: To evaluate the effectiveness and feasibility of cisplatinum for palliative treatment of advanced cervical cancer in a resource-poor setting. METHODS: An observational case series is reported from a university teaching hospital in Kenya. All women presenting with advanced cervical cancer and planned for palliative cisplatinum therapy from 2010 to 2014 were included. Women were treated with cisplatinum 50 mg/m2 every 4 weeks in an outpatient setting. Data on tumor stage and symptoms control were prospectively collected in an electronic database. The main outcome measure was control of symptoms such as bleeding, discharge, and pain. RESULTS: Of the women who originally presented with bleeding, 62% reported improvement in this symptom, 31.3% reported the bleeding completely stopped, 58% had improvement of their vaginal discharge, and 20.5% reported complete resolution. Of the women who presented with pain, 54% reported improvement; 30.9% reported pain had completely resolved. After each treatment cycle, approximately 30% of patients did not return for their next treatment. CONCLUSION: Cisplatinum as palliative treatment of advanced cervical cancer is feasible in a resource-poor setting and leads to effective symptom control. However, unknown barriers may inhibit women from returning for regular treatment.

Development of a comprehensive and sustainable gynecologic oncology training program in western Kenya, a low resource setting.

To provide information on the development of a gynecologic oncology training program in a low-resource setting in Kenya. This is a review of a collaboration between Kenyan and North American physicians who worked together to develop a gynecologic oncology training in Kenya. We review the published data on the increase of cancer incidence in sub-Saharan Africa and outline the steps that were taken to develop this program. The incidence of cervical cancer in Kenya is very high and is the leading cause of cancer mortality in Kenya. WHO identifies cancer as a new epidemic affecting countries in sub-Saharan Africa. In Kenya, a country of 45 million, there is limited resources to diagnose and treat cancer. In 2009 in western Kenya, at Moi University there was no strategy to manage oncology in the Reproductive Health department. There was only 1 gynecologic oncologists in Kenya in 2009. A collaboration between Canadian and Kenya physicians resulted in development of a gynecologic oncology clinical program and initiation of fellowship training in Kenya. In the past 4 years, five fellows have graduated from a 2 year fellowship training program. Integration of data collection on all the patients as part of this program provided opportunities to do clinical research and to acquire peer reviewed grants. This is the first recognized fellowship training program in sub-Saharan Africa outside of South Africa. It is an example of a collaborative effort to improve women's health in a low-resource country. This is a Kenyan managed program through Moi University. These subspecialty trained doctors will also provide advice that will shape health care policy and provide sustainable expertise for women diagnosed with a gynecologic cancer.

Use of visual inspection with acetic acid, Pap smear, or high-risk human papillomavirus testing in women living with HIV/AIDS for posttreatment cervical cancer screening: same tests, different priorities.

OBJECTIVES: Few studies have addressed optimal follow-up for HIV-infected women after cervical treatment. This study aimed to compare performance of three available tests to detect posttreatment cervical disease in HIV-infected women in Kenya. DESIGN: This is a prospective cohort study. METHODS: At least 6 months following cryotherapy, 517 HIV-infected women were evaluated concurrently with visual inspection with acetic acid (VIA), papanicolaou (Pap) smear, and high-risk human papillomavirus (HR-HPV) testing. Women positive by any test (≥low-grade squamous intraepithelial lesion for Pap) were scheduled for colposcopy and biopsy. Among 248 with histological confirmation [and 174 assumed to be truly negative for cervical intraepithelial neoplasia (CIN)2+ after testing negative by all three tests], the ability of each test alone, or in combination, to detect CIN2+ was calculated to determine their utility in posttreatment follow-up. RESULTS: The median age of women was 35 years, 68% were WHO stage 1-2, with a median CD4 cell count of 410 cells/µl, and 87% were on combination antiretroviral therapy. At a median of 6.3 months posttreatment, 64% had an abnormal screen by VIA, Pap, and/or HR-HPV. Among women with histological confirmation, 72 (30%) had persistent/recurrent CIN2+. As single tests, Pap correctly classified the most cases (83%) and had the highest specificity [91% (88 and 95%); sensitivity 44% (35 and 53%)], whereas HR-HPV had the highest sensitivity [85% (75 and 96%); specificity 54% (49 and 58%)]. VIA was not sensitive [27% (18 and 36%)] for the detection of posttreatment CIN2+ [specificity 82% (79 and 86%)]. CONCLUSION: With the goal to minimize the number of false negatives (e.g. not miss CIN2+ posttreatment) in this population that is high-risk due to both prior cervical disease and HIV infection, HR-HPV-based algorithms are recommended.

Successes and challenges of establishing a cervical cancer screening and treatment program in western Kenya.

OBJECTIVE: To describe the challenges and successes of integrating a public-sector cervical screening program into a large HIV care system in western Kenya. METHODS: The present study was a programmatic description and a retrospective chart review of data collected from a cervical screening program based on visual inspection with acetic acid (VIA) between June 2009 and October 2011. RESULTS: In total, 6787 women were screened: 1331 (19.6%) were VIA-positive, of whom 949 (71.3%) had HIV. Overall, 206 women underwent cryotherapy, 754 colposcopy, 143 loop electrical excision procedure (LEEP), and 27 hysterectomy. Among the colposcopy-guided biopsies, 27.9% had severe dysplasia and 10.9% had invasive cancer. There were 68 cases of cancer, equating to approximately 414 per 100000 women per year. Despite aggressive strategies, the overall loss to follow-up was 31.5%: 27.9% were lost after a positive VIA screen, 49.3% between biopsy and LEEP, and 59.6% between biopsy and hysterectomy/chemotherapy. CONCLUSION: The established infrastructure of an HIV treatment program was successfully used to build capacity for cervical screening in a low-resource setting. By using task-shifting and evidence-based, low-cost approaches, population-based cervical screening in a rural African clinical network was found to feasible; however, loss to follow-up and poor pathology infrastructure remain important obstacles.
