Five-year Survival Rate of Prostate Cancer in Iran: Resultsof the national cancer-registry system during 2010-2015

Prostate Cancer is recognized as the second cause of death due to cancers among men worldwide.Due to the lack of local evidence on the survival rate of patients with prostate cancer, this study aimed to esti-mate the 5-year survival rate of patients afflicted with this condition in Iran.

This studymade use of information on 9,772 prostate cancer cases who were registered in the National Cancer Registryduring 2010-15. A telephone survey, with a response rate of 35%, was conducted to gather additional informa-tion such as death status, demographic characteristics, and clinical profile. Kaplan-Meier estimates was used toestimate five-year survival rates.

The overall five-year survival rate of prostate cancer was 82% (95% CI:80-83%). Significantly higher five-year survival rates were observed among retired patients (rate: 94%,95%CI:92-96), patients receiving a combination of radiotherapy and surgery (rate: 92%,95%CI: 89-94), and patients re-siding in rural areas (rate: 92%, 95%CI: 90-93).

We found that various factors such as occupation,area of residence, and the type of medication, may influence on survival rate of prostate cancer. Careful evalua-tion and understanding of effective factors are required to adopt proper health policies and treatment options.Due to the importance of etiologic and epidemiological data, inclusion of such data into the national registrysystem for Prostate Cancer is strongly recommended
