title: [Analysis of prognostic factors of 110 patients with metastatic ovarian tumors from gastric cancer].
abstract: OBJECTIVE
  To explore the clinicopathalogical features, treatment methods and prognostic factors of metastatic ovarian tumors from gastric cancer.
  
  
  METHODS
  Clinical data of 110 gastric cancer patients with metastatic ovarian tumor between January 2001 and August 2015 of Tianjin Medical University Cancer Institute and Hospital were reviewed retrospectively. Univariate and Cox regression model multivariate analyses were performed to investigate the risk factors of metastatic ovarian tumor from gastric cancer.
  
  
  RESULTS
  The follow-up duration ranged from 3 to 60 months (mean 12 months). The follow-up rate was 94.5%(104/110). 104 cases underwent surgical treatment, including satisfactory cytoreductive surgery (57 cases) and unsatisfactory cytoreductive surgery (47 cases). The median overall survival was 12 months and median progression-free survival was 8 months. The survival rates of 1-, 3- and 5-year were 48.1%, 7.7% and 0, respectively. Univariate analysis revealed that pattern of metastasectomy, number of metastatic lymph node, cytoreductive surgery level, presence of peritoneal metastasis or not when ovarian metastasis was diagnosed, ovariectomy prior to primary gastric cancer and extent of ovarian metastatic lesion were associated with prognosis(P<0.05). Multivariate analysis revealed that extent of ovarian metastatic lesion(RR=2.76, 95% CI: 1.68 to 4.54, P=0.005), presence of peritoneal metastasis when ovarian metastasis was diagnosed (RR=0.21, 95% CI: 0.11 to 0.41, P=0.003) and cytoreductive surgery level(RR=3.67, 95% CI: 2.13 to 6.33, P=0.011) were independent prognostic factors.
  
  
  CONCLUSIONS
  Prognosis of patients with metastatic ovarian carcinoma from gastric cancer is quite poor. Extent of ovarian metastatic lesion and peritoneal metastasis were independent prognostic factors. Optimal cytoreduction is associated with better survival.
