In this paper, we illustrate the possibilities of modern online tools for mathematical computations of linear equation analysis systems and show a detailed algorithm a was done for a group of patients with stomach cancer (n = 221). Using the construction of a 9-variable system that is simple enough to understand, specific factors have been established that formed the formula for calculating the survival rate of gastric cancer patients operated radically in the Odessa Regional Oncology Dispensary in the period 2007–2013. Survival of this group of patients was calculated using the computer program "Regional Cancer Registry". The role in the survival of patients of such factors as the degree of primary tumor differentiation, the expression of TP53oncoprotein, the degree of infiltration of stomach wall from T1 = 1 toT4a = 4, T4b = 5, the number of regional lymph nodes in which metastases are found, measured by a morphologist after removal and some other factors.
