[Trends in stomach carcinoma. A statistical analysis of 1204 cases].
The authors report a retrospective analysis of their experience of gastric cancer. One thousand two hundred and four patients, observed between 1977 and 1994, of whom 1,094 underwent surgery, were studied. Data analysis was performed, dividing this period as follows: 1977-1982, 1983-1988, 1989-1994. The results reveal that, over time, substantial changes occurred both in tumor characteristics and surgical approach. With regards to tumor characteristics, the disease weighs heavily, even if it is less frequent than in the past (25% reduction), striking younger subjects and presenting in increasingly more aggressive forms [higher frequency of proximal (+11.4%) and diffuse forms (+18.1%), reduction of advanced forms (-11.6%) not proportional to the increase of early forms (+64.5%), as well as increase of cases with a short clinical history (+15.2%)]. In terms of surgical approach, while the use of conservative surgery was reduced during the study period, extensive procedures were more widely used, particularly in the curative treatment of advanced tumors (subtotal gastrectomies: reduction of 39.5%; total gastrectomies: increase of 106%). The increasing use of extended surgery is linked to the modifications occurred in tumor characteristics and in pre and post-operative management rather then to changes in surgical approach. It must be noted, however, that such technical advances have not yielded an improvement in survival (p = n.s.); as such, it is likely that gastric cancer has became a more aggressive disease and, therefore, has counterbalanced the benefits of early diagnosis and extended exeresis.
