Objective To investigate the clinicopathologic features,the complications of splenectomy and the survival of epithelial ovarian cancer patients with splenic metastasis.Methods A retrospective study was performed of 32 pailents with epithelial ovarian cancer who underwent splenectomy for tumor cytoreduction at Zhejiang Cancer Hospital between Jan 1998 and Jun 2006.Results Of 32 patients,23 patients(72%)were serous adenocarcinoma and 9 were non-serous adenocarcinoma.According to pathological grade,none was of G1,11 were of G2,21 were of G3.Postoperatively,20 patients were left with no residual tumor.7 were with≤2 cm and 5 were with＞2 cm residual tumor.Postoperative complications developed in 8 patients(25%),including subphrenic abscess,wound infection,gastric perforation,gastrorrhagia,phlebothrombosis,and bowel obstruction.The median follow up was 38 months,estimated 2-year and 5-year overall survival were 70%and 36%.Univariate analysis revealed that histological grade,residual tumor and courses of chemotherapy were influencing factors of the survival(P＜0.05),but multivariate analysis indicated that only residual tumor and courses of chemotherapy independently influenced survival(P＜0.05).Conclusions In epithelial ovarian cancer patients with splenic metastasis,low grade serous adenocarcinoma is most common.Splenectomy as part of cytoreductive surgery is associated with modest morbidity and mortality.Residual tumor and courses of chemotherapy are independent factors associated with the prognosis of the patients.

The purpose of the present study was to investigate Norovirus infection status among patients with virus diarrhea in Xiamen city and provide evidence for exploring the prevalence characteristics and constituting appropriate control strategy.From April 2007 to July 2008,323 fecal samples of virus diarrhea cases collected from 3 surveillance hospitals in Xiamen were detected for antigen and RNA by ELISA and Real-Time RT-PCR respectively.The RdPd genes from some samples were furtherly amplified and sequenced for genogroup identification when the Real-Time RT-PCR detection results were positive.In the 323 fecal specimens,68 (21.05%) were positive for Norovirus antigen by ELISA and 107 (31.13%) were positive for Norovirus RNA by Real-Time RT-PCR.The overall positive prevalence rate of Norovirus in Xiamen was 38.08%.107 positive specimens were detected by Real-Time RT-PCR and results showed that 80 strains were Norovirus GGⅡ(74.77%),2 strains were GGⅠ(1.87%) and 25 strains (23.36%)were unidentified.It's indicated that Norovirus infection in Xiamen district was mainly caused by Norovirus GGⅡ,and Norovirus was also the main cause for virus diarrhea.
