Comparison of Definitive Cervical Cancer Management With Chemotherapy and Radiation Between Two Centers With Variable Resources and Opportunities for Improved Treatment.

PURPOSE: Cervical cancer remains a major health challenge in low- to middle-income countries. We present the experiences of two centers practicing in variable resource environments to determine predictors of improved radiochemotherapy treatment. METHODS AND MATERIALS: This comparative review describes cervical cancer presentation and treatment with concurrent chemoradiotherapy with high-dose-rate brachytherapy between 2014 and 2017 at the National Radiotherapy Oncology and Nuclear Medicine Center (NRONMC) in Korle-Bu Teaching Hospital, Accra, Ghana, and Moffitt Cancer Center (MCC), Tampa, FL. RESULTS: Median follow-up for this study was 16.9 months. NRONMC patients presented with predominantly stage III disease (42% v 16%; P = .002). MCC patients received para-aortic node irradiation (16%) and interstitial brachytherapy implants (19%). Median treatment duration was longer for NRONMC patients compared with MCC patients (59 v 52 days; P < .0001), and treatment duration ≥ 55 days predicted worse survival on multivariable analysis (MVA; P = .02). Stage ≥ III disease predicted poorer local control on MVA. There was a difference in local control among patients with stage III disease (58% v 91%; P = .03) but not in survival between MCC and NRONMC. No significant difference in local control was observed for stage IB, IIA, and IIB disease. CONCLUSION: Although there were significant differences in disease presentation between the two centers, treatment outcomes were similar for patients with early-stage disease. Longer treatment duration and stage ≥ III disease predicted poor outcomes.

External Beam Radiation Therapy and Brachytherapy for Cervical Cancer: The Experience of the National Centre for Radiotherapy in Accra, Ghana.

PURPOSE: Most women with cervical cancer in Sub-Saharan Africa present with locally advanced disease. These women require external beam radiation therapy and brachytherapy for curative treatment, but data on their outcomes remain sparse. We report data on treatment characteristics, follow-up, toxicity, and cancer outcomes in a large population of patients from the National Centre for Radiotherapy in Accra, Ghana. METHODS AND MATERIALS: The charts of patients treated from 2006 to 2011 were reviewed. Patients treated without brachytherapy or with palliative intent were excluded. Staging computed tomography scans were not routinely performed. Cobalt 60 external beam radiation therapy was followed by 2 low-dose-rate brachytherapy insertions. Concurrent weekly cisplatin was recommended. Because many patients experienced delays from diagnosis to treatment, we calculated overall survival and locoregional recurrence from the date of first radiation therapy to the event date-or last follow-up when no event recurred-using the Kaplan-Meier (product-limit) method. RESULTS: We included 250 patients with a median age at diagnosis of 55 years. The International Federation of Gynecology and Obstetrics stage was IIB or lower in 63% of patients. The median dose to point A was 83 Gy (range, 60-97.5 Gy). The median doses to the bladder and rectal points were 71 Gy and 65 Gy, respectively. Of the patients, 69% received ≥4 cycles of concurrent cisplatin. The median overall treatment time was 73 days. The median follow-up period was 2.4 years, with 3-year overall survival and locoregional recurrence rates of 86% and 19%, respectively. The most commonly reported late side effect was vaginal stenosis and shortening, occurring in 32% of patients. We also identified nearly 300 patients who were offered curative treatment but never returned to start treatment. CONCLUSIONS: We report promising outcomes in a population of women with cervical cancer treated with concurrent chemoradiation therapy and brachytherapy in Ghana. To our knowledge, this is the largest series of its kind, and it demonstrates what can be achieved with a well-established cancer program in Sub-Saharan Africa.
