A Minimally Invasive Approach to Lobectomy After Induction Therapy Does Not Compromise Survival.
BACKGROUND: The objective of this study was to evaluate the impact of a video-assisted thoracoscopic (VATS) approach on outcomes in patients who underwent lobectomy after induction therapy. METHODS: Outcomes of patients with T2-T4, N0, M0 and T1-T4, N1-N2, M0 non-small-cell lung cancer who received induction chemotherapy or chemoradiation followed by lobectomy in the National Cancer Data Base (2010-2014) were assessed using Kaplan-Meier, propensity score-matched, multivariable logistic regression and Cox proportional hazards analyses. RESULTS: In the National Cancer Data Base, 2887 lobectomy patients met inclusion criteria (VATS 676 [23%]; thoracotomy 2211 [77%]). Of the VATS cases, patients who underwent induction chemoradiation were more likely to undergo conversion (adjusted odds ratio 1.70, P = .05). Compared with an open approach, VATS was associated with decreased length of stay (median: 5 days vs 6 days, P < .01) and no significant differences in 30-day mortality (VATS [1.5% (n = 10)] vs open [2.6% (n = 58)]; P = .13) and 90-day mortality (VATS [3.7% (n = 25)] vs open [5.6% (n = 124)]; P = .14). There were no significant differences in 5-year survival between the VATS and open groups in both the entire cohort (VATS [50.3%] vs open [52.3%]; P = .83) and in a propensity score-matched analysis of 876 patients; furthermore, a VATS approach was not associated with worse survival in multivariable analysis (hazard ratio 1.02; 95% confidence interval 0.86-1.20; P = .83). CONCLUSIONS: In this national analysis, a VATS approach for lobectomy in patients who received induction therapy for locally advanced non-small-cell lung cancer was not associated with worse short-term or long-term outcomes when compared with an open approach.
