Surgical treatment and prognosis of octogenarians with non-small cell lung cancer

Objective: To explore the clinical characteristics, surgical treatment and prognosis of non-small cell lung cancer (NSCLC) among elderly patients over 80 years. Methods: The clinical data, surgical methods, perioperative management, postoperative complications and prognosis of 52 NSCLC patients aged over 80 years were retrospectively analyzed. Results: Out of 52 cases, 27 had a long-term smoking history (51.9%) and 44 were with other diseases (84.6%). Lobectomy was done in 32 cases (65.4%), sub-lobectomy in 20 cases (38.5%), including pulmonary wedge resection in 16 cases (30.8%) and lung segment resection in 4 cases (7.7%). The postoperative complication rate was 44.2% (23/52); the complication rate after lobectomy was 62.5% (20/32) and that after sub-lobectomy was 25% (5/20), with significant difference between lobectomy and sub-lobectomy (P<0.05). Postoperative mortality was 3.8% (2/52). Pathological TNM staging: I a 27 cases (51.9%), I b 12 cases (23.1%), II a 8 cases (15.4%), II b 3 cases (5.8%) and III a 2 cases (3.8%). The 1-, 3- and 5-year survival rate after operation was 87.1%, 59.8%, 19.1%. The 1-, 3- and 5-year survival rate was 86.0%, 61.8%, 21.5% in the patients after lobectomy; that was 89.0%, 58.3%, 18.7% in the patients after sub-lobectomy, with no significant difference between two surgical methods (P>0.05). Conclusions: Octogenarians with NSCLC are often afflicted with comorbidity, so perioperative management is more complex. Strictly adhering to indications, surgery is still an important treatment of NSCLC patients over 80.
