Results of surgical treatment of stage I and II lung cancer.
Pulmonary resection remains the most appropriate treatment for localised bronchogenic carcinoma, since prognosis and outcome are currently dependent on surgical resectability. A retrospective analysis of our experience with three hundred and thirteen stage I (n=250) and stage II (n=63) patients treated surgically form the basis of this report. The initial pulmonary resection was lobectomy in 173 patients, bilobectomy in 38, sleeve lobectomy in 12, pneumonectomy in 59, wedge excision or segmentectomy in 31. The overall operative mortality was 3.2%; 4.03% for lobectomy and 1.6% for pneumonectomy. Morbidity was observed in 21 (6.7%) patients. Four out of sixteen small cell carcinoma patients had postoperative adjuvant chemotherapy. Survival in patients with stage I tumours was 71% at 5 years and 61% at 10 years compared with 41% at 5 years and 35% at 10 years for patients with stage II disease. The five year survival after pneumonectomy was significantly (p<0.05) better for both stage I and stage II lung cancer than after lobectomy. Five year survival in stage I carcinoma was not influenced by histological type, while there was statistically significant difference (p<0.05) in survival between adenocarcinoma (0%) and squamous cell carcinoma (46%) in stage II disease. We conclude that an aggressive surgical approach can provide an excellent prognosis for recovery and long term cure in most patients with early stage lung cancer.
