Stage at diagnosis and survival among adult patients with cancer in Rwanda: A population-based study.

There are marked disparities in cancer survival in low-income countries compared to high-income countries, yet population-based data in the first is largely lacking. In this study, data from the national cancer registry of Rwanda were examined for 542 patients diagnosed with eight of the most common cancers of adults stomach (C16), colorectum (C18-20), liver (C22), breast (female) (C50), cervix (C53), ovary (C56), prostate (C61), and non-Hodgkin lymphomas (C82-85) between 2014 and 2017. Subjects were randomly selected for active followed-up to calculate 1-, 3-, and 5-year observed and relative survival (RS) by cancer type and stage.

Stage at diagnosis and survival by stage for the leading childhood cancers in Rwanda.

Background: The lack of accurate population-based information on childhood cancer stage and survival in low-income countries is a barrier to improving childhood cancer outcomes.

Methods: In this study, data from the Rwanda National Cancer Registry (RNCR) were examined for children aged 0-14 diagnosed in 2013-2017 for the eight most commonly occurring childhood cancers: acute lymphoblastic leukaemia, Hodgkin lymphoma (HL), Burkitt lymphoma (BL), non-Hodgkin lymphoma excluding BL, retinoblastoma, Wilms tumour, osteosarcoma and rhabdomyosarcoma. Utilising the Toronto Childhood Cancer Stage Guidelines Tier 1, the study assigned stage at diagnosis to all, except HL, and conducted active follow-ups to calculate 1-, 3- and 5-year observed and relative survival by cancer type and stage at diagnosis.
