Objectives: Although the standard treatment for patients with stage IIIA non-small cell lung cancer (NSCLC) is chemoradiotherapy, some patients are considered for trimodality therapy [TT]. We analyzed outcomes for stage IIIA NSCLC, treated with TT and compared them with concurrent chemoradiotherapy [con-CRT]. Materials and methods: Patients treated between January 2007 and December 2011 were retrospectively analyzed. Not included were patients with sulcus superior tumors, unknown T/N-status, or recurrent disease after con-CRT followed by surgery. All patients were discussed at our multidisciplinary thoracic tumor board (MTB). Results: Mean Charlson Comorbidity Index was 2 for TT and con-CRT patients. TT patients were younger (median TT = 56 years vs. con-CRT = 62 years; p = 0.001) and had less advanced cN-stage (TT cN2 = 41% vs. 83% for CRT; p < 0.001). 44% of TT patients had T4-stage vs. 12% of con-CRT patients. Median RT dose was lower for TT (50 Gy vs. 66 Gy; p = 0.001) and median RT planning target volume (PTV) in TT and con-CRT patients was 525 cm(3) and 655 cm(3) (p = 0.010), respectively. The majority of TT patients had a lobectomy (23/32). Median follow-up was 30.3 months (95% CI = 18.7-41.9) for TT and 51 months (95% CI = 24.9-77.4) for con-CRT. Median overall survival was not reached for TT and was 18.6 months (95% Cl = 12.8-24.4) for con-CRT (p = 0.001). For PTV = 500 cm(3), median OS for TT was not reached/33.9 months and 29.1/17.1 months for con-CRT. TT patients with cN0/1 had better survival than those receiving con-CRT (p = 0.015), but those with cN2 did not (p = 0.158). The 90-day mortality from start of RT was 0% (0/32) for TT and 1.7% (1/58) for con-CRT. 90-day post-operative mortality for TT was 3.1% (1/32, event unrelated to TT). Conclusions: Selected patients with IIIA NSCLC treated with TT had favorable long-term survival with acceptable short-term mortality. These outcomes support the decision-making and function of our MTB/treatment team. The role of TT in cN2 disease and large tumors merits further evaluation. (C) 2014 Elsevier Ireland Ltd.
