Survival of lung cancer patients residing in Tomsk region (2004-2013)

A 10-year survival of 3482 lung cancer patients residing in Tomsk region was studied. Based on the populationAbased cancer registry data, the observed, corrected and relative survival rates were calculated by the actuarialmethod taking into consideration age, sex, disease stage and place of residence of the patients. Survivalrates were lower in males than in females: the difference in the overall observed survival (OS) rate was from5.1 % (8-year OS) to 7.3 % (2-year OS). An inverse relationship between survival and cancer spread wasobserved. Survival rates were higher for urban populations than for rural populations. The analysis indicatedthat most lung cancer cases were diagnosed at an advanced stage. Survival rates demonstrated relativelyequal levels of cancer care in different regions of Russia. When comparing survival rates in Tomsk regionwith those in Europe and the USA, it was shown that one-year survival was lower in Tomsk regionthan in Europe and the USA, thus indicating more effective cancer screening programs in Europeancountries and the USA.
