Fig 1 Classification based on the extent of well differentiated bronchiolo-alveolar carcinoma (BAC) within the tumor tissue. (A) Type I, tumor has no BAC component (0%). (B) Type II, tumor less than 50% BAC. (C) Type III, more than 50% BAC. (D) Type IV 100% BAC. The right-upper corner shows a high-power magnification of each tumor tissue.

Fig 2 (A) Postoperative overall survival among all the patients (n = 206). (B) Postoperative disease-free survival (DFS) among the patients undergoing potentially curative operation (n = 190). The groups with less of a BAC component showed a significantly worse prognosis (overall survival, p = 0.0009; DFS, p < 0.0001).

Fig 3 (A) Postoperative overall survival among the patients with stage I disease (n = 151). (B) Postoperative disease-free survival (DFS) among the stage I patients undergoing potentially curative operation (n = 149). Type II patients showed a significantly worst prognosis (overall survival, p = 0.0007; DFS, p < 0.0001). In contrast, type I patients showed rather the same prognosis as type III patients.
