Many studies connected with different aspects of the quality of life (QL) h
ave been increasingly reported. In this study we have been used FACT questi
onnaire to estimate QL in three groups of cancer patients receiving chemoth
erapy. Questionnaires were completed by 177 patients. Adverse effects of tr
eatment severely influence the cancer patients QL. The mast significant wor
sening of QL was noticed in the group of lung cancer patients receiving the
most emetogenic chemotherapy (i.e. cis-platinum, vepesid). In other two gr
oups (gastric and colorectal cancer patients) side effects of chemotherapy
caused relatively less QL deterioration. This finding implicates possibilit
y of intensifying the course of treatment (dosage and duration) assuming th
ere is no hematopoetic insufficiency.
