Abstract
Background
Cervical cancer (CC) is the most common female cancer in many countries of sub‐Saharan Africa (SSA). We assessed treatment guideline adherence and its association with overall survival (OS).

Methods
Our observational study covered nine population‐based cancer registries in eight countries: Benin, Ethiopia, Ivory Coast, Kenya, Mali, Mozambique, Uganda, and Zimbabwe. Random samples of 44‐125 patients diagnosed 2010‐2016 were selected in each. Cancer‐directed therapy (CDT) was evaluated for degree of adherence to National Comprehensive Cancer Network (USA) Guidelines.

Results
Of 632 patients, 15.8% received CDT with curative potential: 5.2% guideline‐adherent, 2.4% with minor and 8.2% major deviations. CDT was not documented or without curative potential in 22%; 15.7% were diagnosed FIGO IV disease. Adherence was not assessed in 46.9% (no stage or follow‐up documented 11.9%) or records not traced (35.1%). The largest share of guideline‐adherent CDT was observed in Nairobi (49%), the smallest in Maputo (4%). In FIGO I‐III patients (n=190), minor and major guideline deviations were associated with impaired OS: hazard rate ratio (HRR) 1.73, 95% confidence interval (CI) 0.36‐8.37; and HRR 1.97, CI 0.59‐6.56 respectively. CDT without curative potential (HRR 3.88, CI 1.19‐12.71) and no CDT (HRR 9.43, CI 3.03‐29.33) showed substantially worse survival.

Conclusion
We found only one in six cervical cancer patients in SSA received CDT with curative potential. At least one‐fifth and possibly up to two thirds of women never accessed CDT, despite curable disease, resulting in impaired OS. Investments into more radiotherapy, chemotherapy, and surgical training could change the fatal outcomes of man
