RISK FACTORS EFFECTING MORTALITY AMONG PATIENTS EXPOSED TO PET-CT
Abstract
The aim of the study is to investigate the risk factors of radiation and non-radiation nature influencing the mortality among patients examined using PET-CT. Material and methods. The data for the period from 2010 to 2019 were analyzed. In a multivariate model using logistic regression, the significance of the impact of risk - the ionizing radiation due to radiation therapy, computed tomography, occupational exposure of workers, as well as non-radiation risk factors such as gender, age, stage of malignancy and chemotherapy has been analyzed. Results and conclusions. The study showed a significant increase in the mortality depending on stage of malignancy, as well as amount of previous computed tomography examinations. There was no significant relationship with age at first examination, gender of the patient, the number of PET studies performed, and radiation therapy for overall mortality among patients examined using PET-CT.
