Resultados. De los 165 pacientes intervenidos por cáncer gástrico, 35 presentaban un cáncer gástrico precoz (21,2%), siendo las cifras muy similares en el grupo I (13 de 61, 21,3%) y en el grupo II (22 de 104, 21,1%). Las circunstancias diagnósticas fueron cualitativamente diferentes entre ambos grupos, sólo en 7 pacientes del grupo I el diagnóstico fue el resultado de un estudio sistemático, mientras que en el grupo II fueron 20 los enfermos diagnosticados gracias a una sistemática de estudio (p < 0,05). La supervivencia fue del 94,1% a los 5 años y se mantiene dicha cifra a los 10 años.
Patients and methods. We studied the 165 patients treated surgically for gastric cancer in our center between 1980 and 1996, divided into two groups. Group I was comprised of those treated from 1980 to 1986 and group II, from 1987 to 1996. Thirty-five patients (21.2%) were diagnosed as having EGC, 13 of 61 patients in group I and 22 of 104 in group II. We reviewed the diagnostic circumstances in the two groups, considering 3 categories: a) systematic study; b) postoperative diagnosis, and c) incidental diagnosis. The actuarial survival was calculated according to the Kaplan-Meyer method.
Results. Of the 165 patients who underwent surgery for gastric cancer, 35 presented EGC (21.2%), a rate that was similar to those observed in both group I (13 of 61; 21.3%) and group II (22 of 104; 21.1%). The diagnostic circumstances in the two groups were qualitatively different. In group I, the diagnosis was the result of systematic study in only 7 cases, while in group II, 20 cases were discovered on the basis of systematic study (p < 0.05). The 5-year survival rate was 94.1%, a level that was maintained at 10 years.
