2. Fig 1
Three-year overall and recurrence-free survival rates of patients with different tumor subtypes. (A) Three-year overall survival rates were 98%, 97%, and 85% for patients with lepidic predominant invasive adenocarcinoma (LPA [solid line]), papillary and acinar predominant invasive adenocarcinoma (PA [dashed line]), and solid and micropapillary predominant invasive adenocarcinoma (SM [dotted line]) tumors, respectively. Survival rates significantly differed among groups (LPA versus PA, p = 0.099; LPA versus SM, p < 0.001; PA versus SM, p = 0.032). (B) Three-year recurrence-free survival rates were 98%, 88%, and 64% for patients with LPA (solid line), PA (dashed line), and SM (dotted line) tumors, respectively. Survival rates significantly differed among groups (LPA versus PA, p = 0.014; LPA versus SM, p < 0.001; PA versus SM, p < 0.001).
