Study on 10 Year Follow-up after Radical Gastrectomy for Stomach Cancer

ABSTRACT

A retrospective study was made from 468 cases of stomach cancer from January 1980 to December 1985 in Gospel Hospital, Kosin Medical College. The purpose of this report is to clarrify the 10 year survival rate and prognostic factors. The results were as follows: 1) There was a male preponderance with a male to female ratio of 1.7:1. The peak incidence of age was 6th decade. 2) In 468 radical gastrectomized patients, the most common primary site was lower one-third of stomach(61.2%). 3) About stage distributions, 8.8% of patients were in stage Ia, 19.7% in Ib, 26.5% in II, 24.1% in IIIa, 17.5% in IIIb and 3.4% in IV. 4) The 10 year survival rates according to T and N factors were 86.4% in T1, 54.4% in T2, 37.4% in T3, and 15.6% in T4 ; 64.5% in N0, 32.5% in N1, and 18.4% in N2(P=0.0001) 5) The 10 year survival rates according to methods of operation were 46.5% in subtotal gastrectomy and 15.3% in total gastrectomy. 6) The 10 year survival rates according to WHO pathologic classification were 20% in papillary, 47.2% in well differentiated tubular, 48.2% in moderately differentiated tubular, 32.4% in poorly differentiated, 32.1% in mucinous, and 25.0% in signet ring cell type. 7) The 10 year survival rates according to Lauren classification were 46.3% in intestinal, 28.9% in diffuse, and 38.7% in mixed type.
