Sequential surgical resection of hepatic and pulmonary metastases from colorectal cancer

# The Author(s) 2010. This article is published with open access at Springerlink.com Background Resection of isolated hepatic or pulmonary metastases from colorectal cancer is widely accepted and associated with a 5-year survival rate of 25–40%. The value of aggressive surgical management in patients with both hepatic and pulmonary metastases still remains a controversial area. Materials and methods A retrospective review of 1,497 patients with colorectal carcinoma (CRC) was analysed. Of 73 patients identified with resection of CRC and, at some point in time, both liver and lung metastases, 17 patients underwent metastasectomy (resection group). The remaining 56 patients comprised the non-resection group. Primary tumour, hepatic and pulmonary metastases of all patients were surgically treated in our department of surgery, and the results are that of a single institution. Results The resection group had a 3-year survival of 77%, a 5-year survival of 55 % and a 10-year survival of 18%; median survival was 98 months. The longest overall survival was 136 months; six patients are still alive. In the resection group, overall survival was significantly higher than in the non-resection group (p<0.01). Independent from the chronology of metastasectomy, 5-year survival was 55 % with respect to the primary resection, 28 % with respect to the first metastasectomy and 14 % with respect t

Predictors of early recurrence after resection of colorectal liver metastases

BACKGROUND: Early recurrence after resection of colorectal liver metastases (CLM) is common. Patients at risk of early recurrence may be candidates for enhanced preoperative staging and/or earlier postoperative imaging. The aim of this study was to determine if there are any risk factors that specifically predict early liver-only and systemic recurrence. METHODS: Retrospective analysis of prospective database of patients undergoing liver resection (LR) for CLM from 2004 to 2006 was undertaken. Early recurrence was defined as occurring within 18 months of LR. Patients were classified into three groups: early liver-only recurrence, early systemic recurrence and recurrence-free. Preoperative factors were compared between patients with and without early recurrence. RESULTS: Two hundred and forty-three consecutive patients underwent LR for CLM. Twenty-seven patients (11%) developed early liver-only recurrence. Dukes C stage and male sex were significantly associated with early liver-only recurrence (P < 0.05). Sixty-six patients (27%) developed early systemic recurrence. Tumour size ≥3.6 cm and tumour number (>2) were significantly associated with early systemic recurrence (P < 0.001). CONCLUSIONS: It is possible to stratify patients according to the risk of early liver-only or systemic recurrence after resection of CLM. High-risk patients may be candidates for preoperative MRI and/or computed tomography-positron emission tomography (CT-PET) scan and should receive intensive postoperative surveillance
