[Reoperation for lung cancer: indications and operation methods in cardiopulmonary function]

A second pulmonary resection after initial operation for lung cancer was performed 20 patients (10 with a second primary lung cancer, 8 with a metastatic lung cancer, 2 with lung abscess in pulmonary aspergillosis). All patients had radical lobectomy in first operation. Eight patients underwent completion pneumonectomy, one patient had another lobectomy, two patients underwent wedge resection after initial ipsilateral lobectomy. One patient underwent contralateral lobectomy seven patients had contralateral wedge resection after initial lobectomy. Any patient did not dead within 30 days after the reoperation, not hospital death and major complications. When a second pulmonary resection (especially, completion pneumonectomy) is required, its radicality and the need to preserve residual respiratory function and cardiac function (FEV1.0 more than 800 ml/body and %FVC more than 35%, total pulmonary vascular resistance at the unilateral pulmonary artery artery occlusion test less than 700 dyne.sec.cm-5/m2) must be considered in making the decision to operation. The five-year survival rate after reoperation for patients with lung cancer was 41.0% according to the Kaplan-Meier methods. Patients with a second primary lung cancer (the three-year survival rate, 83.5%) have appeared to do better than those with pulmonary metastasis from lung cancer (the five-year survival rate, 25.6%) These results suggest that reoperation for lung cancer can be done safety, patients undergoing reoperation have a reasonable prospect for long-term survival.
