The state of cancer care in Russia: epidemiology and survival in patients with the most common and life-threatening solid malignant tumors. Part 1. (Population study)

Solid tumors [solid - firm, non-hematopoietic, i.e. developing not from cells of the hematopoietic system] constitute the majority of malignant tumors. The most important factors for their development are: size, degree of sprouting into surrounding tissues, spread throughout the body in the form of regional and distant metastases. The most common, i.e. have the highest incidence rate, solid malignant tumors (SMT) in Russia are three ones: lung, stomach and breast cancer. The most life-threatening (i.e. have the worst survival rates (among those detected, the largest proportion dies)) are liver and pancreatic cancer. We paid particular attention to the impact of coronavirus infection pandemia on morbidity, mortality as well as registration quality of patients with SMT. In order to evaluate the effectiveness of conducted anticancer measures, we calculated survival rates of patients.
