[Outcome analysis of simultaneous liver resection for synchronous liver metastases from colorectal cancer].

OBJECTIVE

To analyze the outcomes of simultaneous liver resection for patients who have primary colorectal cancer with synchronous hepatic metastases to see if there is any advantage for doing so.

METHODS

We retrospectively analyzed the medical records (1999 - 2009) of 53 consecutive patients with synchronously recognized primary colorectal carcinoma and hepatic metastases who underwent simultaneous (40 patients) or two-stage (13 patients) colonic and hepatic resections performed at our hospital.

RESULTS

There was no thirty-day mortality in both groups. The two groups had significant differences in mean operation duration [(212.9 ± 72.3) min vs. (326.5 ± 140.2) min, P = 0.014], mean blood loss [(337.5 ± 298.0) ml vs. (594.6 ± 430.5) ml, P = 0.020], post-operative hospital stay [(16.2 ± 8.1) day vs. (25.8 ± 8.5) day, P = 0.001]. The incidence rates of post-operative complications were 25.0% (10/40) and 53.8% (7/13), respectively, in the two groups (P = 0.053). The 1-, 3-, 5-year survival rates in the simultaneous resection group were 95.0%, 57.0% and 37.4%, respectively, with a median overall survival of 40.0 months and median disease-free survival of 14.0 months. The 1-, 3-, 5-year survival rates in the two-stage resection group were 92.3%, 58.7% and 36.7%, respectively, with a median overall survival of 38.0 months and median disease-free survival of 13.0 months. There were no significant differences between the two groups in respect of their survivals (P > 0.05).

CONCLUSIONS

Simultaneous colectomy and hepatectomy are safe and efficient for colorectal cancer patients who have synchronous colorectal liver metastases, with less complications and blood loss, and shorter hospital stay compared with the two-stage resection.
