RESUMO
BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a major cause of cancer morbidity and mortality in Eastern Africa. The majority of patients with ESCC in Eastern Africa present with advanced disease at the time of diagnosis. Several palliative interventions for ESCC are currently in use within the region, including chemotherapy, radiation therapy with and without chemotherapy, and esophageal stenting with self-expandable metallic stents; however, the comparative effectiveness of these interventions in a low resource setting has yet to be examined. METHODS: This prospective, observational, multi-center, open cohort study aims to describe the therapeutic landscape of ESCC in Eastern Africa and investigate the outcomes of different treatment strategies within the region. The 4.5-year study will recruit at a total of six sites in Kenya, Malawi and Tanzania (Ocean Road Cancer Institute and Muhimbili National Hospital in Dar es Salaam, Tanzania; Kilimanjaro Christian Medical Center in Moshi, Tanzania; Tenwek Hospital in Bomet, Kenya; Moi Teaching and Referral Hospital in Eldoret, Kenya; and Kamuzu Central Hospital in Lilongwe, Malawi). Treatment outcomes that will be evaluated include overall survival, quality of life (QOL) and safety. All patients (≥18 years old) who present to participating sites with a histopathologically-confirmed or presumptive clinical diagnosis of ESCC based on endoscopy or barium swallow will be recruited to participate. Key clinical and treatment-related data including standardized QOL metrics will be collected at study enrollment, 1 month following treatment, 3 months following treatment, and thereafter at 3-month intervals until death. Vital status and QOL data will be collected through mobile phone outreach. DISCUSSION: This study will be the first study to prospectively compare ESCC treatment strategies in Eastern Africa, and the first to investigate QOL benefits associated with different treatments in sub-Saharan Africa. Findings from this study will help define optimal management strategies for ESCC in Eastern Africa and other resource-limited settings and will serve as a benchmark for future research. TRIAL REGISTRATION: This study was retrospectively registered with the ClinicalTrials.gov database on December 15, 2021, NCT05177393 .

PURPOSE: Cervical cancer (CC) is the leading malignancy in Tanzania. Low-income countries are faced with double epidemics of HIV and CC. This study aimed to investigate how HIV and cancer stage at diagnosis affect early treatment outcomes among women with CC treated with concurrent chemoradiation in Tanzania in the highly active antiretroviral therapy era. MATERIALS AND METHODS: This was a prospective cohort study of patients newly diagnosed with CC at the Ocean Road Cancer Institute from November 2019 to January 2020. The tumor response was assessed using RECIST 3 months post-treatment. The tumor response was categorized as a complete or partial response according to the ultrasound and pelvic examination findings. The univariate and multivariate logistic regression explained the relationship between several covariates (age, stage, HIV status, equivalent dose in 2 Gy fractions, chemotherapy cycles, and treatment time) and treatment response. RESULTS: A total of 102 patients with CC were included in this study at baseline. After adjusting for other covariates, only completion of treatment within 56 days (odds ratio [OR], 9.23; 95% CI, 1.53 to 55.85; P = .016) and receiving at least three cycles of cisplatin (OR, 5.6; 95% CI, 1.47 to 21.34; P = .012) were significantly associated with complete tumor response. HIV status was not significantly associated with complete tumor response (OR, 1.534; 95% CI, 0.424 to 5.545; P = .5144). CONCLUSION: Early treatment response was independent of HIV status. With wide coverage of anitretroviral therapy, patients with HIV can receive radical treatment and have the same early outcomes as their HIV-negative counterparts.

INTRODUCTION AND IMPORTANCE: HPV-related carcinoma with adenoid cystic carcinoma-like features currently known as HPV-related multiphenotypic sinonasal carcinoma (HMSC) is a rare distinct head and neck high-risk HPV-related carcinoma. The high-risk HPV subtypes implicated are particularly type 33,35 and 56. So far this is the first reported rare case of a variant of sinonasal carcinoma in Tanzania. CASE PRESENTATION: We present a 59-year old female who presented with a history of right-sided nasal obstruction and intermittent epistaxis for about one year and later on had ipsilateral proptosis. A provisional diagnosis of advanced right-sided malignant sinonasal tumor was made. Trans nasal biopsy revealed HMSC. CLINICAL DISCUSSION: The patient had a right sided fixed neck mass that measured about 7.5 × 8.2 cm. Magnetic resonance imaging (MRI) of the paranasal sinuses revealed a T1 weighted contrasted images that showed a huge extensive enhancing mass (estimated to measure 4.5 × 4.4) involving the nasal cavity, bilateral ethmoid sinuses, frontal and sphenoid sinuses and also the tumor exhibit intracranial extension (anterior cranial fossa) and tend to compress medial walls of both orbits though more marked on the right side. Histopathology and immunohistochemistry confirmed HPV-related multiphenotypic sinonasal carcinoma. The disease was staged to be T4bN3aM0 and the patient was referred for palliative chemoradiation. CONCLUSION: Although HMSC presents at advanced stage in close to half of cases and has a high-grade histological appearance it paradoxically exhibits a relatively indolent manner with frequent local recurrences. Prompt histopathological diagnosis is important to prevent metastases and HMSC-related deaths.
RESUMO
PURPOSE: In Tanzania, cancer of cervix is the most commonly diagnosed cancer and is the leading cause of cancer-related deaths. There are very little data about survival of patients with cervical cancer after treatment in Tanzania. The aims of this study were to determine 5-year overall survival (OS) rate and its predictors among patients with cervical cancer treated at Ocean Road Cancer Institute (ORCI) from January to December 2012. MATERIALS AND METHODS: This was retrospective study done at ORCI by reviewing medical charts of 202 patients with cervical cancer treated at ORCI from January to December 2012. A structured questionnaire was used to extract information about characteristics of the respondents. Survival curves were estimated by using Kaplan-Meir analysis and were compared by using log-rank test. RESULTS: The 5-year OS rate was 26%. The mean and median survival times were 33.9 and 19 months, respectively. Factors that were positively associated with 5-year OS rate include the hemoglobin level more than 9 g/dL at presentation, early International Federation of Gynecology and Obstetrics stage at presentation, high dose of radiotherapy, and use of concurrent chemoradiotherapy. Histology type and HIV status were not associated with survival. CONCLUSION: The 5-year overall survival rate was 26%. Predictors of OS were hemoglobin level, stage at presentation, radiotherapy dose, and the use of concurrent chemoradiotherapy.
