Surgical Treatment for Lung Cancer in Octogenarians

Purpose We conducted this study in order to determine how we should perform the surgical treatment for clinical stage I non-small cell lung cancer (NSCLC) in octogenarians.Methods Thirty-three octogenarians with clinical stage I NSCLC participated in this study. They were retrospectively divided into two groups: one group of 11 patients who underwent a lymph node dissection (ND group), and one group of 22 patients who did not undergo this procedure (ND0 group). We analyzed the surgical invasiveness, morbidity, mortality, and survival in both groups.Results The morbidity rate in the ND group (45%) was higher than that in the ND0 group (23%); however, the difference was no statistically significant (P = 0.1805). There was no significant difference in the overall survival rates of the two groups (P = 0.1647), and the median survival time of the ND0 group (76 months) was slightly longer than that of the ND group (26 months). There was no significant difference in local recurrence rate between the two groups (9.1% vs 4.5%, P = 0.6059).Conclusion We thus conclude that a limited operation without lymph node dissection might be the best surgical treatment for carefully selected octogenarians with clinical stage I NSCLC.
