Abstract
One hundred and forty patients underwent surgical treatment for early gastric cancer. Cumulative and age-corrected cumulative 5-year survival rates were 87.5% and 96.2%, respectively. Cumulative and age-corrected 10-year survival rates were 68.5% and 88.3%, respectively. When cancerous tissue did not remain in the resectional stumps and no regional lymph node was metastasized, the survival was almost equal to that of the general population. Resection of the secondary lymph nodes is considered beneficial, since 13.9% of cases had metastasized lymph nodes in our series. The 5-year survival of 90% is a realistic figure for early gastric cancer, attainable in a general hospital which does not specialize in cancer research.
Résumé
Cent quarante malades ont été traités chirurgicalement pour cancer précoce de l'estomac.
Les taux de survie à 5 ans non corrigés et corrigés en fonction de l'âge se sont élevés respectivement à 87,5% et 96,2%.
Le taux de survie a été le même que celui concernant la population en général dès lors que l'éradication du cancer avait été complète et que les ganglions régionaux n'étaient pas envahis. La résection des ganglions est bénéfique puisqu'aussi bien 13,9% des ganglions étaient envahis dans cette série.
Un taux de survie à 5 ans de 90% peut être obtenu en cas de cancer gastrique précoce même dans un hôpital général sans vocation oncologique spécifique.
Resumen
El cancer gástrico temprano, que también ha sido denominado carcinoma de extensión superficial o carcinoma in situ, se define como una lesión en la cual la invasión tumoral se limita a la mucosa o submucosa, sin consideración de las metastasis ganglionares. En la actualidad el cáncer gástrico temprano representa aproximadamente el 20 a 30% de todos los casos de cáncer gástrico en el Japón.
Evaluaciones masivas mediante exámenes radiológicos del tracto gastrointestinal con bario y biopsia endoscópica rutinaria de las lesiones sospechosas han contribuído al logro de esta elevada tasa de detección. Las tasas acumulativas y corregidas para edad de supervivencia a 5 años fueron de 87,5% y 96,2% respectivamente. En ausencia de tejido canceroso residual en el muñón gástrico y de metástasis ganglionares regionales, la supervivencia fue casi igual a la de la población general. La resección de los ganglios linfáticos secundarios es considerada como beneficiosa, puesto que el 13,9% de los casos en nuestra serie presentaba metástasis ganglionares. La supervivencia a cinco años de 90% para cáncer gástrico temprano es una cifra realista que puede ser lograda en un hospital general no especializado en investigación de cáncer.
