[Video-assisted thoracic surgery for metachronous lung cancer].
Of 1,391 patients who underwent operation for primary lung cancer between 2000 and 2009, 50 patients (3.6%) had a past history of pulmonary resection for lung cancer. Three patients underwent completion pneumonectomy by thoracotomy and in the other 47 patients video-assisted thoracic surgery (VATS) was performed. We considered 42 cases (3 of completion pneumonectomy and 39 of VATS) to be metachronous lung cancer and 8 cases of VATS to be recurrence by detailed histologic assessment. We examined 39 cases of metachronous lung cancer resected by VATS. The patients were aged 68 +/- 8 years and 4 patients were aged 80-years or more. The surgical procedures performed were lobectomy in 4 patients, segmentectomy in 3, and wedge resection in 40. The operation time was 121 +/- 66 minutes and the blood loss was 67 +/- 140 ml. There were no major complications. We registered 6 deaths during follow-up; 3 were due to disease progression and 3 were due to other causes. The survival rate of the 42 patients including 3 patients who underwent completion pneumonectomy was 74.9% at 5 years. Early detection of metachronous lung cancer and surgical resection offers a favorable prognosis.
