ABSTRACT
Objective To retrospeetivley explore the expanded radicM resectable range and improved Surgical approach of the progressive pancreatic head cancer with metastasis of portal vein(PV) and liver,and try to improve the resectable rate.survival rate and quality of life.Methods The patients witll late pancreatic cancer sis of partial PV resection and 8 cases of left leaf or right leaf sectional hepatectomy partial were involved in 27 cases,reconstructed gastrointestinal tract with improved Whipple interposed Y-type jejunostomy and PV.27 cases were randomly divided into intervention chemotherapy of treatment groups(n=13) and control groups(n=14).Results Severe complications or dead cases were not found in 27 cases after operation.The 2-,3-,5-years survival rates were 61.5%,38.4%,23.0%,and 42.8%,21.4%,14.3% in treatment group and control group,respectively.The survival rate was statistically different(P<0.05).Conclusions The expanded radical pancreatoduodenectomy and its improved surgical approach can improve not only the survival rate but also the quality of life.
ABSTRACT
Objective To investigate the effect of infiltrated mast cells on the biological characteristics of uterine carcinoma.Methods Twelve leiomyomas,ten uncertain malignant uterine leiomyomas,and seven uterine leiomyosarcomas were studied with light microscopy for the morphometry about their histological feature,mast cell particle and factor Ⅷ-related antigen(FⅧRAg);Cell apoptosis was measured by flow cytometry.The correlative analysis was carried out between the mast cell and others factors.Results Comparing with smooth muscle tumors of uncertain malignant potential(4209.9?273.0),the count of tumor cell was the highest in leiomyosarcoma(3557.6?346.3)(P
