| * Scores transformed to 0–100 scale per EORTC manual. Higher functional or global scores indicate better QoL; higher symptom scores indicate worse symptoms. EORTC QLQ-C30 – European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30; MCID – minimum clinically important difference; QoL – quality of life. | ||||||
