The aimof the present study was to estimate observed and relative cancer survival rates in populations of Phu Tho,Hanoi and Hue city. Methods: A retrospective-cohort study was performed for all 12 districts of Phu Tho province(semi-highland area in the north), eight districts of Hanoi city (Capital) and four districts of Hue city in centralarea). Seven indicators were collected for each case of cancer death: name, age, sex, date of the first diagnosishaving cancer, date of death, the cause of death and full address. Two steps were done. Firstly, we collectedname, age, sex, date of death, the cause of death and full address; secondly, we collected date of the first diagnosishaving cancer by a household visit by trained interviewer. Survival time was calculated from the date of deathminus the date of diagnosis for each case of cancer. Observed survival rates for 1-year, 2-years, 3-years, 4-yearsand 5-years were estimated by the form of survival number multiplied by 100 then corrected for the registerednumber of cancer cases. For relative survival rates, the observed survival rates were corrected for the generalpopulation survival rate. Results: Males and females combined, for all cancer sites, 1-year, 2-year, 3-year, 4-yearand 5-year observed and relative survival rates were 23.8%-23.9%, 8.5%-8.5%, 3.8%-3.8%, 2.6%-2.6%, 1.7%-1.7%, respectively. The highest one-year relative cancer survival rate was seen in the capital, Hanoi city (49,8%),followed by Hue city in the central area (24,7%), and the lowest in Phu Tho, north-semi-highland (21.8%).Conclusions: The better cancer survival in Hanoi than in Phu Tho province, as well as the results overall, pointto a need for greater efforts in early detection and treatment, especially in rural areas. %U https://journal.waocp.org/article_24650_6af06934f6e2026dacf8cdf3891da28f.pdf
