Purpose: The aim of this study was to evaluate quality of life (QoL) in patients with gastric adenocarcinoma receiving adjuvant chemoradiotherapy (CRT).
Methods: The European Organization for Cancer Research and Treatment Quality of Life Questionnaire-Core 30 (QLQ-C30) and site-specific module for gastric cancer (QLQ-STO22) were administered at four time points to 156 patients admitted to Cumhuriyet University Oncology Center between 2011 and 2018.
Results: The patient group comprised 76% men and 24% women with a median age of 61 years (range, 18-88). During CRT, 12 patients (8%) discontinued treatment, 25 (16%) lost weight, and 42 (27%) had reduced performance. There was significant worsening in QLQ-C30 global health status and all functional and symptom scale scores at CRT completion. These changes were also clinically significant except for physical functioning scores and were supported by minimal clinically important difference measurements. In the QLQ-STO22, all symptoms except dry mouth and hair loss were negatively affected at CRT completion. In general, scores were improved at 1 month after CRT and almost all scores reached baseline level by 6 months. Certain scores were more adversely affected in women (global health status, physical functioning, role functioning, fatigue, pain, and insomnia), those who lost weight during CRT (emotional functioning), and those with CRT interruption (emotional functioning and anxiety).
Conclusion: Although CRT reduces QoL in patients with gastric cancer, the effects tend to resolve within 6 months after completing treatment. Female sex, weight loss, and CRT interruption negatively affected some QoL scores.
