Patient-Reported Outcomes From Patients Receiving Immunotherapy or Chemoimmunotherapy for Metastatic Non–Small-Cell Lung Cancer in Clinical Practice

Abstract

IntroductionImmunotherapy and chemoimmunotherapy clinical trials for metastatic non–small-cell lung cancer (mNSCLC) have generally excluded patients with poor performance status (PS) and have utilized patient-reported measures that could miss some symptoms associated with immunotherapy. The goals of this study were to describe quality of life and symptom burden among mNSCLC patients receiving immunotherapy in clinical practice, and to examine burden by Eastern Cooperative Oncology Group performance status (ECOG PS) and age. Patients and MethodsBetween 2017 and 2018, mNSCLC patients receiving immuno/chemoimmunotherapy at an academic medical center completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) and the National Cancer Institute Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). Univariate and bivariate analyses described EORTC-QLQ-C30 subscales and the proportion reporting at least moderate PRO-CTCAE symptoms, and compared scores by ECOG PS (0/1 vs. 2/3) and age (< 70 vs. ≥ 70 years). ResultsSixty patients (60% female; 75% < 70 years old; 68% ECOG PS 0/1; 57% receiving single-agent immunotherapy) participated. The mean EORTC-QLQ-C30 global health score was 62.6; EORTC symptoms were highest for fatigue, insomnia, dyspnea, and financial concerns (all > 30). Global health and pain were worse in ECOG PS 2/3 patients. For PRO-CTCAE, 20% to 40% reported at least moderate gastrointestinal, respiratory, dermatologic, arthralgia, or myalgia symptoms. The PRO-CTCAE pain score was higher among ECOG PS 2/3 patients. ConclusionIn clinical practice, global health was largely comparable to published clinical trials, but PRO-CTCAE items indicated a higher symptom prevalence. Closer monitoring of symptoms is warranted in ECOG PS 2/3 patients.
