Abstract

Background/Aims: The putative influence of tumor location on the biologic behavior of gastric carcinomas remains controversial. The aim of this study was to investigate if carcinomas arising in the three types of gastric mucosa (cardia, fundus/body and antrum) have different clinical and pathologic profiles and carry a different prognosis. Methods: Three hundred and two patients with cardia or gastric carcinoma resected between 1984 and 1996 were retrospectively studied. Cases were divided in three groups according to tumor location: cardia (n = 80); fundus/body (n = 60); antrum (n = 162). The three groups were crosstabulated with clinic and pathologic parameters, such as age, sex, macroscopy, histology, desmoplasia, tumor size, depth of tumor wall penetration, nodal status, venous invasion and stage. Survival rates were calculated for the three locations according to the aforementioned parameters. Univariate survival analysis and Cox regression were performed for each location. Results: Cases from the cardia and fundus/body were similar and distinct from antrum cases according to macroscopy, tumor size, depth of wall penetration, venous invasion, nodal status and stage. Cases from fundus/body were similar to antrum cases and distinct from cardia cases according to gender and Laurén’s classification. An overall difference in survival between the three locations was observed (p = 0.006). Cumulative survival was better for patients with carcinomas in the antrum than in the cardia (p = 0.04) and in the fundus/body (p = 0.003); no significant differences were observed in survival between cardia and fundus/body carcinoma cases. Cox regression identified stage and venous invasion as prognostic factors for patients with carcinomas in the three locations. In the group of cardia tumors, older patients had a worse outcome and in the group of fundus/body carcinomas, large tumors were associated with a poorer survival. Conclusions: Our results show that cardia carcinoma and antrum carcinoma are distinct gastric carcinoma entities whereas fundus/body carcinoma shares some characteristics from both entities.

Clinical significance of p53 mutations in adenocarcinoma of the esophagus and cardia.

D Shibata, P Chandrasoma, T DeMeester … (2000)

To compare the frequency and spectrum of p53 gene mutations in adenocarcinomas of the esophagus and cardia and to compare clinical and pathologic features in patients with p53 mutant and nonmutant cancers. The p53 gene is commonly mutated in human cancers, and a p53 mutation is reported to be present in more than 50% of esophageal adenocarcinomas. Although many studies have investigated the frequency of p53 protein overexpression in adenocarcinomas of the esophagus or esophagogastric junction, few studies have assessed the frequency and clinical significance of p53 mutations in these tumors. In particular, the prognostic importance of p53 mutation is uncertain. Adenocarcinomas of the esophagus and cardia share many epidemiologic and pathologic features, but it is controversial whether they represent the same tumor. A comparison of the frequency and spectrum of mutations in adenocarcinomas of the esophagus and cardia would test whether these tumors are also similar at the molecular level. DNA was isolated from microdissected paraffin-embedded tumor tissues of patients who underwent esophagogastrectomy for adenocarcinoma of the esophagus (n = 19), cardia (esophagogastric junction, n = 12), or subcardia (n = 6). Exons 5 to 8 of the p53 gene were analyzed for the presence of mutations using the polymerase chain reaction with single-strand conformation polymorphism and DNA sequencing of bands showing abnormal mobility. The presence of mutation was confirmed by selective hybridization of a mutant-specific oligonucleotide to DNA isolated from the tumor. p53 mutations were identified in 18 of 37 (48.6%) tumors. Patients with p53 mutant tumors were significantly younger and had a significantly poorer prognosis. There was a similar prevalence of p53 mutations in adenocarcinomas of the esophagus (53%) and cardia (58%). In contrast, mutations were relatively uncommon in subcardia adenocarcinomas (one mutant tumor [17%]). The types of mutations found in the esophageal and the cardia cancers were also similar. Adenocarcinomas of the esophagus and cardia have a similar frequency and spectrum of p53 gene mutations, suggesting that these tumors have a common pathogenesis. Patients with mutations are younger, have signs of more advanced disease, and have a poorer prognosis than patients without mutations.

Surgical management of adenocarcinoma of the cardia.

G Fradet, Adele Evans, I. Clifton … (1998)

The incidence of adenocarcinoma of the cardia is increasing. The surgical management remains controversial. The present study reviews our experience with surgically resected adenocarcinoma of the cardia. A retrospective review of 153 cases of surgically resected adenocarcinoma of the cardia was performed. Preoperative radiotherapy was used in 31 patients. The surgical approach, morbidity, mortality, impact of preoperative radiotherapy, and survival were determined. The type of resection performed was a transhiatal esophagogastrectomy in 78%, a transthoracic esophagogastrectomy in 21%, and a transabdominal esophagogastrectomy in 1%. The in-hospital mortality rate was 4%. The frequency of complications was not associated with the use of preoperative radiotherapy or surgical approach. The 1-year (61%), 2-year (38%), 3-year (23%), and 5-year (16%) survival were not affected by the use of preoperative radiotherapy or surgical approach. Survival was significantly associated with stage and the presence of lymph node metastasis. Adenocarcinoma of the cardia is associated with a poor long-term prognosis. The long-term survival does not appear to be affected by the use of preoperative radiotherapy or by surgical approach.
