The influence of age on the growth and spread of gastric carcinoma.
A twelve year series of 375 patients with gastric carcinoma has been studied. Patients were divided into TNM Groups. Tumours were classified as intestinal-type and diffuse. The patients with T1-3NOMO diffuse tumour were ten years younger than the patients with T1-3NOMO intestinal-type tumour. The mean age increased from T1 through T2 to those with T3 tumour. The age differences between the T-stages were the same in both groups, which indicate that once started, the diffuse and the intestinal-type tumours infiltrate the gastric wall at about the same rate. Among the patients with intestinal-type tumour, those with lymph node or distant metastases were three to seven years younger than the patients without metastases. On the other hand, the patients with diffuse tumour and metastases were as many years older than the patients without metastases. Apparently, tumour spread is age dependent and different between the two types of gastric carcinoma. The ill repute of the diffuse gastric carcinoma may therefore be explained by the advanced stage of that tumour at the time of treatment as compared to the intestinal-type tumour. The diffuse tumour seems to be clinically more silent and to give symptoms at a later stage than the intestinal-type tumour.
