N2 - Indications for thoracoscopic metastatectomy remain controversial because not all metastatic tumors may be detected without the manual palpation that is possible with thoracotomy. However, the accuracy (92%) of preoperative lung imaging in patients with one or two lesions led us to re- evaluate thoracoscopic metastatectomy with patient survival as the primary end point. Thoracoscopic wedge resection using an endoscopic stapling device or video-assisted thoracic surgery (VATS) lobectomy was performed in patients with one or two pulmonary metastases. Thoracoscopic resection was performed in 27 patients with 22 solitary lesions and 5 patients with two lesions. The primary tumors were colorectal cancer (15), testicular cancer (3), osteosarcoma (2), and seven other histologies. In 5 of 27 patients (18.5%) a thoracoscopic operation was converted to a VATS procedure, which requires minithoracotomy to identify metastasis primary by digital palpation. The 3- year survival rate for colorectal cancer patients who underwent thoracoscopic resection was 56.4%, in comparison to 48.6% in historical control thoracotomy patients (n = 16). There was no statistically significant difference between the two groups. Thoracoscopic resection of one or two colorectal cancer lung metastases results in a survival rate similar to standard thoracotomy, and thereby provides an acceptable alternative to this more invasive approach.
