Clinicopathological features and outcome of hepatic resection for liver metastasis from gastric cancer.

BACKGROUND/AIMS
The efficacy of operative resection of lesions metastatic to the liver from colorectal or neuroendocrine tumor is well established. However, the appropriate management of liver metastasis from gastric cancer is controversial. We analyzed the prognostic factors in patients who underwent hepatectomy for metastasis from gastric cancer.


METHODOLOGY
Retrospective clinical and pathological study in Tokyo Metropolitan Bokutoh Hospital. Ten patients underwent hepatectomy for metastases from gastric cancer out of 1807 patients with gastric cancer between 1981 and 1998.


INTERVENTIONS
Clinical investigation and histopathological examination of resected specimen.


MAIN OUTCOME MEASURES
Survival, recurrence, liver metastases and lymph node metastases.


RESULTS
The 1-, 3-, and 5-year survival rates of these ten patients were 50%, 30%, 20%, respectively. The median survival time was 25 months, and two patients survived longer than five years. The survival time tended to be longer, but not to a significant extent, in patients with no lymph nodal involvement at the primary site (P = 0.067).


CONCLUSIONS
Even though it is rare, a survival time of 5-years can be achieved by resection of gastric cancer metastatic to the liver. These results suggest that a patient with liver metastasis from gastric cancer has a greater chance of surviving long-term if there is no lymph node metastasis at the primary site.
