OBJECTIVE: To asses the incidence of local recurrence and distant metastases after complete resection for stage I lung cancer in order to predict the predominant prognostic factors. METHODS: We retrospectively reviewed 123 patients with stage I lung cancer who underwent curative resection over a 2-year period between January 1987 and December 1988. There were 83 male and 40 female patients with a mean age of 64.8 +/- 12 years (range between 39 and 82 years). Multivariate analysis of prognostic factors for long term survival was undertaken. RESULTS: T1N0 lesions were found in 34 patients and T2N0 in 89. The histological diagnosis was Squamous carcinoma in 75, Adenocarcinoma in 38, large cell carcinoma in 6 and small cell carcinoma in 4 patients. Pneumonectomy was performed in 27 patients (5 T1 and 22 T2) while 96 required lobectomy (29 T1 and 67 T2). At 5 years 50 patients died. This was due to local recurrence in 12, distant metastasis in 24, second primary in 1, unrelated disease in 3, while the cause was unknown in 10 patients. At 5 years, 10 patients were alive with evidence of recurrence. The mean interval for local recurrence was 19.8 months and for distant metastasis was 18 months. The overall 5 year survival was 67% +/- 4 for T1 and 56% +/- 5 for T2 lesions (NS). The rate of recurrence was significantly less for T1 lesions (P = 0.02). Survival was significantly less for patients requiring pneumonectomy rather than lobectomy (P = 0.01) whether for T1 or T2. CONCLUSION: In stage I lung cancer T2 lesions requiring pneumonectomy for complete resection had a worse prognosis and higher incidence of local recurrence.
