This included 27 (24%) who received WBRT, 18 (16%) received STRS, and 1 (1%) who received both WBRT and STRS [Supplementary Figure 1]. Including the total patient cohort, the rates of overall survival were as follows: 1 month = 93%, 6 months = 58%, 1 year = 35%, and 5 years = 17%, with a median survival of 233 days [Figure 1]. Squamous subtyping of NSCLC was a negative predictor of survival (Log rank [Mantel-Cox] P = 0.048) [Figures 1 and 2].

On recursive partitioning analysis [Figure 3] using extent of resection and age, age <70 and confirmed gross-total resection yield a median survival of 27.5 months which was statistically significant (Log rank [Mantel-Cox] P = 0.0001).
