[Metachronous bilateral pulmonary resection for primary bronchogenic carcinoma]

A metachronous bilateral pulmonary resection was executed on 11 cases of primary bronchogenic carcinoma. Of the 11 cases of secondary tumors, 5 were double primaries and 6 were metastatic foci. Except for 1 wedge resection, radical lobectomy was done for the first resection of the 11 cases. Modes for the second resections were lobectomy in 2, segmentectomy in 3, and wedge resection in 6. At the second operation, 2 cases underwent a complete regional lymphnode dissection but in the other 9 cases lymph node dissection was incomplete. Tumor infiltration was proven on the margin of surgical specimen for 2 cases. There was a necessity of ventilatory support for 3 cases after the operation but there were no surgical deaths. Of the 6 cases of recurrent diseases that underwent second resection, 1 case died of respiratory insufficiency a year after operation. The 5 remaining cases are living from 1 to 4 years. Of the 5 double primaries, 1 case died of respiratory insufficiency 7 months after operation and 1 case died of metastatic disease 10 months after operation. One case died of an accident 3 years 6 months after the operation. For the remaining 2 cases, one is living for 1 year and 6 months, the other for 3 years and 4 months following resection. The demand for second resection in primary bronchogenic carcinoma is increasing from year to year.
