Abstract:
Objective To explore the clinical pathological features of gastric cancer and to provide a basis for research and treatment of gastric cancer.Methods From 2001 to 2004,a total of 694 cases of gastric cancer with radical gastrectomy were collected.Gender,age,tumor location,tumor size,World Health Organization (WHO) histological type and grade,Lauren type,blood/lymphatic vessel invasion,lymph node metastasis,depth of tumor invasion (pT) and pathological TNM staging (pTNM) were retrospectively analyzed.Results Among 694 gastric cancer cases,male to female ratio was 3.96∶ 1; a total of 644 cases (92.8％) were aged from 41 to 70,and cases aged from 51 to 70 had a high incidence of gastric cancer.The predilection site for gastric cancer was cardia (33.43％),antrum (28.96％) and the body (21.76％) accordingly.The common WHO histological types were tubular adenocarcinoma (70.32 ％) and signet ring cell carcinoma (24.50 ％).The common histological grades were Ⅱ,Ⅲ and Ⅰ.The intestinal type was most common in Lauren classification,accounting for 58.93 ％; followed by the diffuse type,accounting for 22.33 ％.Blood/lymphatic vessel invasion was detected in 438 cases (63.11％),lymphnode metastasis in 504 cases (72.62％).A total of 319 cases (45.97％) were pT3 stage,241 cases (34.73％) were on pTNM Ⅲ stage.Conclusions In recent years,cardia and antrum are the predilection sites of gastric cancer.Tubular adenocarcinoma and signet ring cell carcinoma are common which indicate that the mechanism of gastric cancer pathogenesis is varied.
