Outcomes of surgery versus chemoradiotherapy in patients with clinical or pathologic stage N3 non-small cell lung cancer.

ABSTRACT: BACKGROUND:Because surgery is rarely recommended, there is minimal literature comparing the outcomes of surgery and chemoradiation in stage N3 non-small cell lung cancer (NSCLC). We examined the outcomes of definitive chemoradiation versus multimodality therapy, including surgery, for patients with clinical and pathologic stage N3 NSCLC. METHODS:The National Cancer Database was used to identify patients with clinical stage T1 to T3 N3 M0 NSCLC and clinical stage T1 to T3 Nx M0 with pathologic stage N3 NSCLC who were treated with either definitive chemoradiation or surgery between 2004-2015. A 1:1 propensity score-matched analysis was used to compare outcomes for both treatment groups in each analysis. The primary outcome was overall survival. RESULTS:In 935 matched patient pairs with clinical stage N3 NSCLC, surgery was associated with worse survival (hazard ratio, 1.52; 95% confidence interval, 1.12-2.05) compared with chemoradiation at 6 months, but was associated with a significant survival benefit after 6 months (hazard ratio, 0.54; confidence interval, 0.47-0.63) in multivariable analysis. In 281 pairs of patients with pN3 NSCLC, surgery had similar survival compared with chemoradiation at 6 months (hazard ratio, 1.71; 95% confidence interval, 0.92-3.19), but was associated with improved survival after 6 months (hazard ratio, 0.76; 95% confidence interval, 0.58-0.99). The complete resection rate was 80% and 73% for patients with clinical stage N3 and pathologic stage N3 disease, respectively. CONCLUSIONS:In patients with clinical or pathologic stage N3 NSCLC, surgery is associated with similar or worse short-term but improved long-term survival compared with chemoradiation. In a selected group of patients with stage N3 NSCLC, surgery may have a role in multimodal therapy.

Project description:Purpose:To investigate the prognostic utility of the prognostic nutritional index (PNI) in stage IIIB non-small-cell lung carcinoma (NSCLC) patients undergoing concurrent chemoradiotherapy (CRT). Methods:A total of 358 stage IIIB NSCLC patients who received a total dose of 60-66 Gy (2 Gy/fraction) radiotherapy and ?1 cycle(s) of platinum-based chemotherapy were analyzed. The receiver operating curve analysis was utilized to identify the optimal PNI cut-off value demonstrating a significant connection with the overall survival (OS), locoregional progression-free survival (LRPFS), and progression-free survival (PFS). Results:At a median follow-up time of 22.5 months (range: 2.4-123.5), 30.2% and 14% of the patients were still alive and free of disease progression, respectively.The median OS, LRPFS, and PFS were 25.2 [95% confidence interval (CI): 36.3-46.6 months], 15.4 (95% CI: 26.6-35.3 months), and 10.7 (95% CI: 36.8-69.9 months), individually, for the whole study accomplice. The ROC analysis revealed an optimum rounded cut-off that associated meaningfully with each of the OS [area under the curve (AUC): 84.1%; sensitivity: 75.9%;72.4% specificity], LRPFS (AUC: 92.4%; sensitivity: 87.9%; 85.1% specificity), and PFS (AUC: 80.1%; sensitivity: 73.7%; 71.6% specificity) at a value of 40.5. Comparative analyses revealed that the patients presenting with PNI?40.5 had significantly inferior OS (16.8 vs 36.7; P<0.001), LRPFS (11.5 vs 19.5; P<0.001), and PFS (8.6 vs 13.6; P<0.001) outcomes compared to patients with PNI>40.5. In univariate analyses, lower T-stage (1-2 vs 3-4; P< 0.001), lower N-stage (N2 vs N3; P< 0.001), anemia status (absent vs present; P< 0.001), weight loss status (<5% vs ?5%; P< 0.001), and PNI group (?40.5 vs >40.5; P<0.001) were the factors found to be associated with OS, LRPFS and PFS results. The results of multivariate analysis exhibited that the PNI was independently associated with each of the OS (P<0.001), LRPFS (P<0.001), and PFS (P<0.001) outcomes. Conclusion:The pretreatment PNI appears to be a robust novel prognostic factor that stratifies patients with stage IIIB NSCLC into two significantly distinct survival groups after CRT.
