Análisis de supervivencia tras metastasectomía pulmonar y hepática en el carcinoma colorrectal= Surveillance analysis after lung and liver metastasectomy in colorectal cancer

Abstract

INTRODUCTION Between 25-50% of the patients with resected colorectal carcinoma are presumed to have recurrence of this disease. The most common sites of metastases are liver and lung. Recently, some series have reported that advances in chemotherapeutic agents and surgical techniques had lead to similar survival rates in patients with both liver and lung metastases compared with those with isolated liver or lung metastases. METHODS Retrospective analysis of 244 consecutive patients who underwent liver and/or lung metastasectomies from January 2000 to December 2010. CONCLUSIONS Surgery for metastatic disease in colorectal cancer is an effective option in terms of survival in selected patients, even in those with liver and lung metastases. Patients who had resection of both liver and lung metastases, had worse survival when disease free interval in-between metastases was less than one year. On the other hand, survival may not be affected by the sequence of the development of metastatic disease.
