OBJECTIVES: We evaluated the pattern of nodal metastasis and its prognosis after radical lymphadenectomy in adenocarcinoma of the gastric cardia.
METHODS: We conducted a retrospective cohort study of 70 patients (52 men and 18 women; mean age 63.6 years) with adenocarcinomas of the gastric cardia who underwent extended gastrectomy (65 total gastrectomies and 5 proximal gastrectomies) and radical lymphadenectomy (D2 to D4) at Taichung Veterans General Hospital between 1989 and 1995.
RESULTS: Twenty-four complications developed in 22 (31.4%) patients, and seven (10.0%) hospital deaths occurred. An overall 5-year cumulative survival of 37.6% was obtained. Lymph node metastases were identified in 53 (75.7%) patients. Nodal involvement was closely related to the depth of tumor invasion (p = 0.005). When the gastric wall invasion was limited to the subserosal layer (T1 and T2, n = 15), no patient had N4 group nodal metastasis. Once the serosal layer had been involved (beyond T3), N4 group nodal metastasis was frequently seen (30.9%, 17 of 55 patients). A multivariable analysis revealed that the level of nodal involvement, the depth of tumor invasion, and the presence of complications were independent prognostic factors. Cumulative 5-year survivals of curability A (n = 12), B (n = 19), and C (n = 32) resections were 100%, 21.2%, and 27.5%, respectively (p = 0.0001). The long-term survival of the patients after resection was also closely related to their pTNM stages (p = 0.0004).
CONCLUSIONS: We conclude that gastrectomy accompanied by radical lymphadenectomy provides a reasonable long-term survival expectancy that is closely related to the stage of the disease and the curability of resection.
