The purpose of the study was to assess the impact of cancer knowledge and patient's lifestyle on QOL and the relationship between QOL and various environmental factors in patients with non-small-cell lung cancer treated with chemotherapy. The study group consisted of 129 patients with metastatic lung cancer patients treated between May 2010 and December 2015 in two centres. The knowledge of cancer and their lifestyle was rated by method of diagnostic survey, using the Behavioral Health Inventory IZZ by Prof. Juczyński. We sought factors affecting to response to treatment, overall survival and quality of life. The general level of knowledge of cancer and the level of health behaviours was low. Ninety percent of lung cancer patients were smokers. The average age of the study group was 64 years. Eighty-nine patients received chemotherapy with cisplatin, 28 schemes containing carboplatin, 6 inhibitors of EGFR tyrosine kinase, and 6 vinorelbine or gemcitabine monotherapy. Complete regression was observed in 2 patients, partial response in 33 patients (26%), stable disease in 51 (40%) and 54 (42%) patients had progression. In multivariate analysis, significant effects on survival were performance status, schemes of treatment and response to treatment. Quality of life before and after treatment did not differ from each other. We found impact on quality of life: performance status, response to treatment and knowledge of cancer and lifestyle. The level of knowledge of oncological patients and their lifestyle observed in clinical practice are associated with QOL.
