摘要：This article concerns the problem of assessing selected body composition parameters after completion of antitumor therapy and comparing them with the same parameters of healthy children. A high percentage of overweight and obesity,as well as abnormal fat distribution in convalescents with cancer shows a significant adverse effect of therapy on body composition and suggests the need for early intervention in terms of diet and exercise,which would help patients to quickly achieve the proper parameters of body composition. Two main problems will be mentioned during the presented data analysis. Firstly, in each group there was a small number of observations. Because of this,the real differences between examined subgroups may have been omitted. Secondarily, many variables are correlated and are not normally distributed. Therefore,beside the standard statistical tests to compare two groups,principal component analysis was applied to reduce the dimensions of the attribute space and to attempt to classify two groups of patients.
