Purpose: Curative lobectomy and systematic lymph node dissection for lung cancer in elderly patients are often associated with increased risk of postoperative morbidity and decreased quality of life. Conversely, avoiding surgery may mean not curing the cancer. We retrospectively examined data on surgery for octogenarians with clinical stage I non-small-cell lung cancer (NSCLC) to assess the safety and prognosis for patients who underwent radical or limited surgery., Methods: Subjects comprised 44 octogenarians who underwent surgery for clinical stage I NSCLC from 1996 to 2008. Preoperative co-morbidities, surgical procedures, postoperative morbidity, and prognoses were compared between radical and limited surgery., Results: A total of 14 patients (32%) underwent complete lobectomy and systematic lymph node dissection (radical surgery), and 30 patients (68%) underwent segmentectomy or wedge resection or limited lymph node dissection (limited surgery). No significant differences in preoperative clinicopathological features were seen between groups except that significantly more clinical stage IA patients were in the limited surgery group than in the radical group. Surgical time was significantly shorter with limited surgery. Frequencies of postoperative morbidity and recurrence were similar for each type of surgery. Overall and disease-specific 5-year survival rates did not differ significantly between groups., Conclusion: Limited surgery is less invasive and is associated with the same prognosis as radical surgery for octogenarians with NSCLC. Limited surgery for this cohort thus appears reasonable to prevent postoperative morbidity, particularly for patients with poor pulmonary reserve.

Objectives: Our registration of surgically treated lung cancer patients in Niigata Prefecture began in 2001. The purpose of this study was to identify the characteristics of patients and surgical treatment of lung cancer., Methods: All patients who underwent resection for lung cancer in Niigata Prefecture from January 2001 to December 2002 were eligible for registration. A total of 31 medical data for each patient were registered., Results: During the 2-year period, 1,211 patients were registered. A total of 605 cases (50%) were detected by mass screening, and 874 cases (72%) were diagnosed preoperatively. There were 718 (59%) c-stage IA cases and 317 (26%) c-stage IB cases. The most common operative procedure was lobectomy; 850 patients underwent single lobectomy. Limited resection was performed in 301 patients (25%), and video-assisted thoracoscopic surgery in 193 (16%). The most common histological type was adenocarcinoma in 860 cases (71%), followed by squamous cell carcinoma in 273 (23%). Pathologic staging yielded stage IA in 635 cases (52%) and stage IB in 262 (22%)., Conclusions: The results of our registration demonstrate a very high ratio of surgically treated stage IA cases in Niigata Prefecture and that limited resection was performed in many patients. Accumulation of these data will reveal the characteristics of lung cancer surgically treated in Niigata Prefecture and will provide a basis for determining the future course of surgical treatment for lung cancer. Registration is continuing, and it will provide new and useful information about lung cancer, eventually including 5-year survival data.

Objective: The purpose of this study was to determine whether lobectomy without radical systematic mediastinal lymphadenectomy (LA) is a satisfactory alternative surgical treatment for octogenarians with clinical stage I non-small cell lung cancer (NSCLC)., Methods: From April 1985 through December 2001, 49 patients aged 80 years and older who underwent surgical treatment for clinical stage I NSCLC were reviewed. Lobectomy without radical systematic mediastinal LA was performed for 27 patients (LA0 group) and lobectomy with radical systematic mediastinal LA was performed for 22 patients (LA group)., Results: The mortality rate was 0% in the LA0 group and 4.5% in the LA group. Five-year survival rate according to the type of surgery was 44.8% in the LA0 group and 55.5% in the LA group, a difference that was not significant (P=0.88). Although there was no significant statistical difference, postoperative pulmonary complication was more frequent in the LA group than in the LA0 group (32% in the LA group versus 11% in the LA0 group P=0.07). Five-year survival rates according to serum carcinoembryonic antigen (CEA) levels were 0% for patients with elevated CEA levels (n=9) and 56.5% for patients with normal CEA levels (n=40) (P<0.01)., Conclusion: Lobectomy without radical systematic mediastinal LA appears to be a satisfactory surgical procedure for octogenarians with clinical stage I NSCLC. However, mediastinoscopy is necessary in such octogenarians if their serum CEA level is elevated so that the precise clinical stage can be determined and an accurate prognosis can be given.
