Return on Investment of a Breast Cancer Screening Program in Tanzania: Opportunity for Patient and Public Education

Breast cancer is the second incident and second cause of cancer mortality among women in Tanzania due to late-stage presentation. The screening clinic at the Ocean Road Cancer Institute (ORCI) can help detect cases early and reduce cost of treatment. We calculated the return on investment (ROI) of the ORCI breast screening clinic. Screening and treatment data of all newly diagnosed breast cancer patients seen at ORCI during 2016–2018 were abstracted from the medical records. Also, data on time, resources, and cost of screening and treatment were obtained. The cost of treating screened patients was compared with cost of treating unscreened patients, and differences in cost of treatment were compared with cost of operating the screening program. Of the 730 total patients, 58 were screened prior to treatment, and 672 were not. There was no significant difference between stage at diagnosis and treatments received by screened and unscreened patients (79.3% late- stage vs 72.2% late-stage diagnosis, respectively (p = .531), or cost of treatment between the two groups (cost, in Tanzanian Shillings, for screened (2,167,155.14 or $954.27) vs unscreened (1,918,592.28 or $844.52), (p = .355). There was also no significant difference in cost of treatment between the screened and unscreened groups and a slightly negative ROI (− 0.05%) from implementing the program. The breast screening clinic in Tanzania has not yet proven its cost-effectiveness in reducing stage with screening. The likelihood that patients have utilized the clinic for treatment rather than early detection is a possible reason for the lack of cost-effectiveness. Future studies should focus on educational initiatives to encourage screening at early disease stage. Public education should increase awareness about the clinic for early detection. The experience of this program is ideal for dissemination to other low-income countries that are initiating cancer early detection and cancer education programs.
