Nodal abdominal spread in adenocarcinoma of the cardia. Results of a multicenter prospective study.
BACKGROUND: Precise knowledge of the abdominal nodal spread of cardia adenocarcinoma in relation to the depth of invasion of the tumor and its longitudinal extension may be very important for the surgeon as a guide in choosing the type of resection and lymphadenectomy.METHODS: The frequency of node metastases in each abdominal station of the first and second tier was prospectively studied in 101 patients with type II and III cardia cancer (defined as approved by the consensus conference held during the second International Gastric Cancer Conference in Munich in April, 1997) who underwent total gastrectomy with D2 lymphadenectomy during the period January 1994 to April 1998. Lymph nodes were retrieved immediately after operation by the surgeon and assigned to the appropriate station according to the classification of the Japanese Research Society for Gastric Cancer.RESULTS: In early gastric cancer, of both type II and type III, lymph node involvement was limited to the perigastric nodes of the upper half of the stomach and to the lymph node station of the celiac trunk. In advanced cancers, whether of type II or type III, there was a fairly high frequency of metastases to the perigastric nodes of the lower half of the stomach; there was also high frequency of metastases at N2 stations, without differences in frequency between pT2 and pT3 tumors (staged according to the classification of the Japanese Research Society for Gastric Cancer).CONCLUSIONS: The results of our study provide evidence for the need to perform a total gastrectomy with D2 lymphadenectomy in all patients with advanced cardia cancer type II or type III. In early cancers, a less extensive resection (proximal gastrectomy) with D2 lymphadenectomy may be indicated.
