Survival in Surgical and Nonsurgical Patients With Superior Sulcus Tumors

Treatments for superior sulcus tumor (SST) have evolved, with induction chemoradiotherapy providing an improved R0 resection rate. We reviewed the treatment and outcomes of SSTs in a single institution to identify prognostic factors and optimal treatment strategy. Methods Details of patients who underwent any type of treatment for SST from 1997 through 2014 were retrospectively collected. Survival was calculated by the Kaplan-Meier method. Proportional hazards regression was used to test the prognostic significance of factors in univariate and multivariate models. Results Eighty-nine patients were identified, 8 of whom had M1 disease and were excluded from the analysis. Of the 48 surgical patients, 44 received preoperative induction treatments, with 12 (25%) achieving a pathologic complete response (pCR), 23 with minimal residual disease, and 9 with gross residual disease. Complete resection was achieved in 40 surgical cases. As expected, nonsurgical patients had worse survival than did surgical patients (median survival, 2.1 versus 5.8 years; nonsurgical versus surgical hazard ratio [HR], 2.1; 95% confidence interval [CI], 1.2–3.7; p = 0.01). By multivariable Cox analysis, smoking status (HR, 4.4; 95% CI, 1.5–13.0; p = 0.01) and previous or concurrent malignancy (HR, 4.73; 95% CI, 1.6–13.9; p = 0.0.005) were prognostic factors for surgical patients. There were no statistically significant prognostic factors for nonsurgical patients. Conclusions Chemoradiotherapy followed by surgical treatment is our favored treatment for operable candidates. Preoperative induction treatments were associated with a 25% pCR rate for surgical patients. Candidates for surgical therapy are expected to have longer survival than those who are not candidates for resection.
