Health-Related Quality of Life and Mid-Term Oncological Outcomes After Subcostal Uniportal Robot-Assisted Lung Cancer Surgery: A Secondary Analysis of a Clinical Trial

Objective: Subcostal uniportal robot-assisted thoracic surgery (URATS) using the da Vinci Single-Port (SP) system avoids intercostal placement of the main robotic access. This prespecified secondary analysis of a prospective trial characterized chronic postsurgical pain and health-related quality of life (HRQOL) as primary patient-reported outcomes after subcostal URATS for early-stage lung cancer, with mid-term oncological outcomes as an exploratory endpoint. Methods: Patients from the parent trial (NCT05535712) undergoing subcostal URATS were assessed at 3, 6, and 12 months by structured telephone interviews. Chronic postsurgical pain was defined by the ICD-11 criterion (Numerical Rating Scale [NRS] > 0 on any of four activity-specific items). Neuropathic features were assessed with the painDETECT Questionnaire (PDQ), and HRQOL with EORTC QLQ-C30 summary score and selected domains. Results: In 33 patients, chronic postsurgical pain declined from 33.3% at 3 months to 6.1% at 12 months (p = 0.004), was mild among symptomatic patients (median NRS 1), and showed no PDQ-defined neuropathic features. Two patients received a 7-day course of gabapentin at 3 months. Baseline HRQOL (median QLQ-C30 summary score 91.5) increased at all postoperative time points (p < 0.001). At a median 40-month follow-up, one patient had bilateral pulmonary recurrence at 13 months, all remained alive, and no delayed hernia or other access-related complication was identified. Conclusions: Subcostal URATS was feasible in this prospective cohort. Chronic postsurgical pain was mild and decreased over time, HRQOL remained well preserved, although data on mid-term oncological outcomes were preliminary.
