The state of cancer care in Russia: breast cancer among the male population. Prevalence and survival of patients (Population study at the federal district level)

Abstract

Breast cancer among the male population is extremely rare. The risk of this pathology among the male population is 129 times less than among the female population. The incidence in "rough" indicators correlates as 0.48 to 93.98 0/0000, a difference of 112 times, in standardized indicators 0.56 to 53.54 0/0000 or 97 times. Out of 21,871 cases of deaths from breast cancer in Russia, only 151 cases occur in the male population. The ratio of "crude" mortality rates among the male and female population is 0.22 and 27.61 0/0000, respectively, standardized - 0.14 and 13.59 0/0000, the difference between these indicators is also 97 times. Calculations of the probable risk of breast cancer should be calculated on the basis of standardized indicators that eliminate the difference in the age composition of the compared population groups. The fact that the probability of the occurrence of breast cancer among the male population is a rare phenomenon is proved by the materials of the handbook prepared by the staff of the P.A. Herzen Moscow Research Oncology Institute. In 2019, no cases of breast cancer among the male population were registered in 35 administrative territories of Russia, and only 1 case was registered in 20 more territories. The Population Cancer Registry created in the North-Western Federal District allows us to approach the assessment of the prevalence of breast cancer among the male population and assess the effectiveness of therapeutic and diagnostic measures carried out, as well as for other rarely occurring diseases, for example, such as heart, eye, thymus and other cancers.
