Background:
The median survival time(MST)of Stage Ⅳ advanced gastric cancer is reportedly 6-13 months. The standard treatment for Stage Ⅳ gastric cancer is systemic chemotherapy. With advancements in chemotherapy, the number of conversion surgery(CS)is increasing.
Aim:
We evaluated the clinical significance of CS for Stage Ⅳ gastric cancer.
Method:
We retrospectively examined the clinicopathological variables and oncologic outcomes of 11 patients with Stage Ⅳ gastric cancer who received CS after induction chemotherapy.
Results:
The MST was 86.4 months in all patients. No significant difference was detected in non-curative clinical factors, pathological type, residual tumor, or Ef-Grade. A longer prognosis could be achieved when an R0 resection was obtained, with excellent histopathologial response, without peritoneal dissemination, and with negative peritoneal lavage cytology.
Conclusion:
This study provides positive evidence that CS for Stage Ⅳ gastric cancer could be performed safely and could possibly provide longer survival in selected patients.
