RESUMO
Objective To study the clinical pathological features,treatment and prognosis of umbilical metastases of intra abdominal malignancies (sister Mary Joseph nodule, SMJN). Methods From January 1980 to July 2003, 17 SMJN cases were admitted. The clinical features were reviewed. Results The diagnosis of SMJN was confirmed by pathology in all cases, including epithelial ovarian carcinoma in 6 cases, gastric adenocarcinoma in 6 cases,colon adenocarcinoma in 2 cases, and endometrial carcinoma, gallbladder carcinoma and undifferentiated adenocarcinoma without identifying primary site in one each. Mean survival、half year、one year and two year survival rate in 10 palliative excision cases was 13 5 months、60%、20% and 10%, which were significantly better than 8 25 months、14 3%、0% and 0% in 7 conservative therapy cases ( P
RESUMO
ObjectiveTo explore risk factors of colorectal cancer with synchronous liver metastases and its prognosis. Methods From Aug 1994 to Feb 2004, 106 colorectal cancer patients with synchronous hepatic metastases were enrolled. Fifteen clinicopathological parameters were collected for mono-variable and multi-variable analysis. Treatment result was analyzed by Kaplan-Meier method and COX regression. Results Bowel obstruction, ascites, pelvic nodules, peritoneal invasion, serosal infiltration, organs involvement, tumor size, circumference of bowel invasion, depth of invasion were all individually relevant with synchronous hepatic metastasis. Logistic regression demonstrates depth of invasion, serosal infiltration, pelvic nodules and ascites were most important factors resulting in synchronous hepatic metastases. Radical resection(57 cases), palliative resection(39 cases) and laparotomy only(10 cases) resulted respectively in mean survival time and median survival time of 41.0 and 34.0 months,23.6 and 18.0 months,16.5 and 12.0 months,respectively (all P=0.0095).Surgery, location of tumor and pelvic nodules were independent prognostic factors. Conclusions Synchronous liver metastasis may present when primary tumor infiltrates serosa, or pelvic nodules and ascites are present. Radical excision significantly improves survival rate.

0. 05) ; whereas Herrmann Ⅲ ,Ⅳand T3 ,T4(depth of invasion) were more often seen in advanced signet cell carcinoma (P 0. 05 ). Conclusion Compared with other pathological types, patients with advanced signet ring cell carcinoma of the stomach are with comparable long term survival.
RESUMO
Objective This experiment was to identify the influence of recombinant human endostatin (rhES) combined with 5-FU on the growth of a xenografted gastric cancer in nude mouse. Methods After the establishment of the model, mice were divided into 4 groups (six in each) receiving respectively, for consecutive 10 days: NS, 5-FU (10 mg/kg) intraperitoneally; rhES (2 mg/kg); and 5-FU + rhES. On 15th day tumor volume was measured. The expression of VEGF, bFGF, VEGF-C, PCNA, bcl-2 and apoptosis index (AI) were examined. The tumor inhibition rate(TIR) and tumor shrinking rate(TSR) were calculated. Results Tumor volume was (43?2) mm 3 in 5 FU+rhES group,(169?45) mm 3 in 5 FU group, (95?28) mm 3 in rhES group, (1057?114) mm 3 in control group ( P
