Sensitivity analysis of early versus late-stage tumors. (A) 1-year survival; (B) 2-year survival; (C) 3-year survival. A single treatment type (radiotherapy plus chemotherapy versus radiotherapy plus chemotherapy plus surgery) was chosen, and studies in adenocarcinoma were removed to reduce between-study variability. Two studies in patients with early- to mid-stage cancer (Burmeister 1995, Smith 1998) were compared with 2 studies in patients with mid- to late-stage cancer (Hainsworth 2007, Hihara 2014).
