Table 4.
Baseline characteristics, treatment-related variables, and long-term outcomes in propensity score matched patients with clinical stage IIIA NSCLC who received combination therapy with chemotherapy and radiation versus those who received trimodality therapy. The CR group refers to patients who received chemotherapy and radiation in any sequence. The trimodality group refers to patients who underwent preoperative chemotherapy and radiation therapy.
