Highlights from the Second Choosing Wisely Africa conference: a roadmap to value-based cancer care in East Africa (9-10 February 2023, Dar es Salaam, Tanzania).

The ecancer Choosing Wisely conference was held for the second time in Africa in Dar es Salaam, Tanzania, from the 9th to 10th of February 2023. ecancer in collaboration with the Tanzania Oncology Society organised this conference which was attended by more than 150 local and international delegates. During the 2 days of the conference, more than ten speakers from different specialties in the field of oncology gave insights into Choosing Wisely in oncology. Topics from all fields linked to cancer care such as radiation oncology, medical oncology, prevention, oncological surgery, palliative care, patient advocacy, pathology, radiology, clinical trials, research and training were presented to share and bring awareness to professionals in oncology, on how to choose wisely in their approach to their daily practice, based on the available resources, while trying to offer the maximum benefit to the patient. This report, therefore, shares the highlights of this conference.

Modern Radiotherapy Technology: Obstacles and Opportunities to Access in Low- and Middle-Income Countries.

Low- and middle-income countries (LMICs) have a large burden of cancer with differential population needs and outcomes compared to high-income countries. Access to radiotherapy, especially modern technology, is a major challenge. Modern radiotherapy has been demonstrated with better utility in overall cancer outcomes. We deliberate various challenges and opportunities unique to LMICs' set up for access to modern radiotherapy technology in the light of discussions and deliberations made during the recently concluded annual meeting of Tata Memorial Centre, India. We take examples available from various LMICs in this direction in our manuscript.

Mortality among Cancer Patients within 90 Days of Therapy in a Tertiary Hospital, Tanzania: Is Our Pretherapy Screening Effective?

BACKGROUND: A high mortality has been reported during the first ninety days of cancer therapy and is more pronounced in patients with febrile neutropenia. The Bugando Medical Center oncology department offers cancer diagnosis and treatment services to the population of the Lake Zone of Tanzania with limited data on the outcome within 90 days of therapy. Here, we report the 90-day mortality and factors associated with it among cancer patients attending the oncology department of the tertiary hospital in Tanzania. Methodology. Enrolled participants underwent baseline physical examinations, and their functional status was assessed using Karnofsky score. On each clinic visit, full blood picture was taken and patients were investigated for infections. Data were entered in the Microsoft Excel, cleaned and coded and then transferred to STATA version 13 for analysis. RESULTS: A total of 102 participants were included in the final analysis. Their median age was 50 years (38-60). The majority of the study participants were females 76 (75%), and 82 (80.4%) had primary school education. The majority of the patients had solid cancer 96 (94.1%). A total of 12 (11.8%) patients died within 90 days of starting therapy. Low hemoglobin level at the start of cancer therapy, Karnofsky score below 80%, and using 5-fluorouracil-containing therapy were statistically significantly found to be associated with mortality within 90 days of therapy among cancer patients. CONCLUSION: One tenth of cancer patients at Bugando Medical Center do not survive within 90 days of therapy; the mortality is significantly high among anemic patients, with poor performance status, on 5-fluorouracil regimen, and diagnosed with head and neck cancer, necessitating close follow-up of these patients.

Cancer incidence and treatment utilization patterns at a regional cancer center in Tanzania from 2008-2016: Initial report of 2,772 cases.

PURPOSE: To describe cancer incidence and treatment utilization patterns at the regional cancer referral center for the Lake Zone of northwestern Tanzania from 2008 to 2016. METHODS: This descriptive, retrospective study reviewed all cancer cases recorded in the Bugando Cancer Registry (BCR), a clinical and pathology based registry at the only cancer referral hospital in the region. Primary tumor site, method of diagnosis, HIV status, and cancer treatment were reported. Using census data, the 2012 GLOBOCAN estimates for Tanzania were scaled to the Lake Zone and adjusted for 2016 population growth. These estimates were then compared to BCR cases using one-sample tests of proportion. RESULTS: A total of 2772 cases were reported from 2008-2016. Among these, the majority of cases (82.5 %, n = 2286) were diagnosed among adults. Most cases (85 %, n = 1923) were diagnosed by histology or cytology. Among adults, the most common cancers diagnosed were cervix (22.7 %, n=520), breast (12.6 %, n=288), and prostate (8.5 %, n=195). Among children, the most common cancers were non-Burkitt non-Hodgkin lymphoma (17.3 %, n=84), Burkitt lymphoma (16.5 %, n=80), and Wilms tumor (14.6 %, n=71). The 1116 BCR cases represent 12.2 % of the 9165 expected number of cancer cases for the Lake Zone (p < 0.001). 1494 cases (53.9 %) received some form of treatment - surgery, chemotherapy, radiation, or hormone therapy - while 1278 cases (46.1 %) had no treatment recorded. CONCLUSIONS: This comprehensive report of the BCR reveals cancer epidemiology and treatment utilization patterns typical of hospitals in low-resource settings. Despite being the only cancer center in the Lake Zone, BMC evaluates a small percentage of the expected number of cancer patients for the region. The BCR remains an important resource to guide clinical care and academic activities for the Lake Zone.

Pediatric Cancer in Northern Tanzania: Evaluation of Diagnosis, Treatment, and Outcomes.

PURPOSE: The majority of new diagnoses of pediatric cancer are made in resource-poor countries, where survival rates range from 5% to 25% compared with 80% in high-resource countries. Multiple factors, including diagnostic and treatment capacities and complex socioeconomic factors, contribute to this variation. This study evaluated the available resources and outcomes for pediatric patients with cancer at the first oncology treatment center in northern Tanzania. METHODS: Qualitative interviews were completed from July to August 2015 to determine available staff, hospital, diagnostic, treatment, and supportive care resources. A retrospective review of hospital admissions and clinic visits from January 2010 to August 2014 was completed. A total of 298 patients were identified, and data from 182 patient files were included in this review. RESULTS: Diagnostic, treatment, and supportive capacities are limited for pediatric cancer care. The most common diagnoses were Burkitt lymphoma (n = 32), other non-Hodgkin lymphoma (n = 26), and Wilms tumor (n = 25). A total of 40% of patients (n = 72) abandoned care. There was a 20% 2-year event-free survival rate, which was significantly affected by patient age, method of diagnosis, and year of diagnosis. CONCLUSION: To our knowledge, this is the first review of pediatric cancer outcomes in northern Tanzania. The study identified areas for future development to improve pediatric cancer outcomes, which included strengthening of training and diagnostic capacities, development of registries and research databases, and the need for additional research to reduce treatment abandonment.
