[Surgical treatment for bilateral multiple lung cancers]

We reviewed 21 patients with bilateral multiple bronchogenic carcinomas. Eleven of them had synchronous carcinomas and 10 had metachronous carcinomas. We treated 6 patients with lobectomy and wedge resection under median sternotomy synchronously, and 2 patients with lobectomy on both lungs under standard thoracotomy, 2 patients with lobectomy and wedge resection, 1 patient with segmentectomy on both lung, 1 patient with lobectomy and segmentectomy, 1 patient with pneumonectomy and wedge resection, and 8 patients with lobectomy and thoracoscopic wedge resection on each lung metachronously. Two patients who had lobectomy on both lungs were dead, one of whom of pulmonary edema 2 weeks after second operation and the other of respiratory failure 3 years after second operation. We concluded that lobectomy on both lungs are not recommended because of high mortality rate (10%) and the limited resection under thoracoscopic surgery should be considered to treat the other contra lateral primary lung cancers.
