Analysis of clinical and pathological features of familial gastric cancer / 中国现代普通外科进展

ABSTRACT

Objective:To explore the clinical and pathological features of familial gastric cancer, and to get the early discovery and early treatment of it.Methods:Two kindreds of familial gastric cancer were followed up and their clinical and pathological features were analyzed.Results:Six patients with gastric cancer were found in the 2 kindreds.Autosomal dominant inheritance was observed in these cases.clinical and pathological features of familial gastric cancer were showed according to the document analysis:early onset;poor prognosis;patients suffer simultaneous or metachronous carcinoma;CDH1 germline mutation carriers had higher penetrance;pathologically, tumors are mostly diffuse infiltrative type with lower differentiated degree and earlier metastasis to lymphnodes;in one kindred,the sites of the lesions were relatively consistent.Conclusion:Familial gastric cancer has particular clinical and pathological featuresearly onset;poor prognosis;patients suffer simultaneous or metachronous carcinoma;CDH1 germline mutation carriers have higher penetrance; pathologically,tumors are mostly diffuse infiltrative type with lower differentiated degree and earlier metastasis to lymphnodes.
