During the period 2008-2011, esophageal cancer comprised 2,5 ± 0,2 % of all cases for males and 0,5 ± 0,1 % for females. Despite worldwide tendency towards decreased incidence of esophageal cancer, the rise in the age-standardized incidence rate was observed for both males and females of Tomsk region from 2000 to 2011. For males, the increase in both crude and age-standardized rates was registered. For females, the same tendency was observed in patients in the 50 to 64 age group.

The authors studied the incidence of malignant neoplasms of the bone and articular cartilage (BAC) in Siberia and the Far East over 1994-2008. The regional, time, and age characteristics of BAC malignancies were analyzed using the sex and age intensive and standardized incidence rates (world standard) per 100,000. Analysis of the results of examining 7069 patients diagnosed as having BAC malignancy over 1994-2008 showed that in the average the regions of Siberia and the Far East showed a reduction in the incidence of malignancies at these sites; its peak being was notified in a 60-74-year age group. Higher incidence rates of BAC malignancies were registered in children aged 15-19 years.
