ABSTRACT
Objective To explore the clinical characteristics of localized peritoneal mesothelioma by the retrospective analysis of the clinical data and its relationship with asbestos exposure.Methods A total of 22 cases with localized peritoneal mesothelioma confirmed by pathological test and they were selected as our subjects in the Central Hospital of Cangzhou from Jan.2007 to Dec.2012.The information of all cases was collected.The incidence,asbestos exposure history,clinical manifestations,imaging studies,pathological type,immunohistochemistry and tumor markers of peritoneal mesotheliom patients were recorded or measured.Results Of 22 cases,female accounted for 68.18％.The periods from onset symptoms to treatment time was from 2 days to 1 year with an average of 83 days.Clinical symptoms were verified including localized abdominal pain (11 cases,50.00％),abdominal mass (8 cases,36.36％),abdominal distension (6 cases,27.27％),ascites (10 cases,45.45％).Patient was with increased platelet and carcinoma antigen 125.Abdominal computerized tomography showed that local mass was seen and 12 cases were with asbestos spot.Ultrasound-guided peritoneal biopsy was confirmed as the main diagnostic method followed by Laparotomy.Epithelial type was the main pathological type (19 cases,86.36％),following the fleshy tumor type and mixed type.Eighteen cases had asbestos exposure history.Conclusion Localized peritoneal mesothelioma is a rare disease.However,the incidence is high in the current region due to asbestos exposure.Abdominal pain and local mass are the main clinical symptoms,and the main pathology is epithelial typeas well as surgery is the main therapy.
