Abstract

Background and purpose: Surgical resection has been the standard treatment recommended for respectable pulmonary metastasis from colorectal cancer. However, we should evaluate again the indication of bilateral thoracotomy and repeat resection of pulmonary metastatic lesions, because these surgical interventions may deteriorate the patients' quality of life. This retrospective study was performed to address this issue.

Patients and methods: The subjects were 39 patients who underwent pulmonary metastatectomy of colorectal cancer between May 1990 and January 2007. The prognosis was evaluated according to the types of thoracotomy, bilateral thoracotomy (n=5), repeat pulmonectomy (n=6), and single thoracotomy (n=28). In addition, the impact of new anticancer drugs (5-fluorouracil+Leucovorin, S-1, irinotecan, and oxaliplatin) on survival after thoracotomy was examined.

Results: The patients undergoing bilateral thoracotomy showed a significantly shorter survival after the last thoracotomy than those in other groups (p=0.03). The survival time after the initial thoracotomy was not different between patients who received new anticancer drugs (n=11) and those without (n=28, p=0.58).

Conclusions: Bilateral pulmonary metastatectomy from colorectal cancer appears to have little benefit on survival, while a repeat metastatectomy may cause a long-term survival. A further collection of cases is needed to conclude whether the new anticancer drugs would be useful for prolonging the patients' survival after pulmonary metastatectomy.
