Abstract

Background: Deterioration in health-related quality of life (HRQOL) is frequently observed after surgery for stage I non-small-cell lung cancer. As stereotactic ablative radiotherapy (SABR) can result in local control percentages exceeding 90%, we studied baseline and post-treatment HRQOL in SABR patients.

Methods: HRQOL data were collected prospectively using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire in 382 consecutive patients treated with SABR. Patients were referred from 68 Dutch centers, with 86% judged unfit for surgery, and 14% declining surgery. An SABR dose of 60 Gy was delivered in three-, five-, or eight treatment fractions, depending on tumor diameter and location. HRQOL data were available for 382 patients at baseline (pre-SABR), and for 282, 212, 144, 56, and 43 patients at 3, 6, 12, 18, and 24 months post-SABR, respectively.

Results: Median survival was 40 months, with a 2-year survival of 66%. Local, regional, and distant failure percentages at 2 years were 6%, 13%, and 22%, respectively. Mean baseline global HRQOL and physical functioning scores were 62.9 ± 1.1 and 61.7 ± 1.1, respectively. Baseline symptom scores were highest for dyspnea (47.1 ± 1.7) and fatigue (37.4 ± 1.3). Except for a nonsignificant decrease in 2 to 3 points per year in physical functioning, no statistically or clinically significant worsening of any of the HRQOL functioning or symptom scores at any follow-up time point was observed.

Conclusions: Patients referred for SABR have substantially worse baseline HRQOL scores than those reported in the surgical literature. Clinically relevant deteriorations in HRQOL subscale scores were not observed after SABR.
