The purpose of this study is to focus on the appearance and intensity of symptoms of patients with cancer undergoing chemotherapy. This study took place with the help of the Esas-r assessment questionnaire, which includes 9 symptom scales. Patients during chemotherapy are asked to fill in the questionnaire with their personal information but mainly they are asked to state the intensity of their symptoms. The scales found in the questionnaire include a measurement from 0 to 10 with 0 indicating mild to no side effects and 10 indicating the highest intensity.
In the following analysis, we made use of two questionnaires. The first contains 189 patients and the results of the first measurement after the first chemotherapy and the second contains 105 patients and the results of the latest measurement after the last chemotherapy. In this study, descriptive measures for both demographics and scales will be presented separately for each measurement. Subsequently, the necessary non-parametric checks have been made between the scales in order to determine their degree of correlation with the patients’ demographics. Finally, the method of multiple logistic regression will be presented separately for both measurements , taking as a response variable the total sum of symptoms and then, nonparametric tests of dependent samples will be performed in order to see how the scales eventually change between measurements.
