Epidemiology, index of accuracy, histological structure, year-by-year lethality and survival of patients with malignant melanoma. Population study – part II

For any research development, we must first make sure that the material selected for research is reliable. Among the six main most reliable criteria for evaluating the performance of cancer services, such as morbidity, mortality, and the level of morphological verification of tumors – the most important indicators are the index of accuracy, primary mortality and survival of patients with malignant tumors. Purpose. To determine the level of index of accuracy for patients with skin melanoma (C43) and its dynamics from 1995 to 2018 in Russia as a whole and in a number of administrative territories. Calculate the 5-year observed and relative survival and typical mortality in the northwestern Federal district of the Russian Federation. Materials and methods of research. The material for the study is statistical collections, including author's ones, and the database of the cancer register of the northwestern Federal district of the Russian Federation. Standard methods of statistical analysis were used. Obtained result. It is important to note that for all administrative territories, whose PCR database were involved in calculating the 5-year observed and relative survival rates, the level of survival rates of patients with melanoma of the skin is significantly lower than the average European (Eurocare–4). Conclusions. Thus, the study revealed a significant improvement in the treatment of patients with malignant melanoma of the skin. At the same time, the estimated 5-year observed and relative survival rates of patients with malignant melanoma of the skin remain relatively low.
