Gastric carcinoma: intestinal metaplasia and tumor growth patterns as indicators of prognosis
Abstract:
We have reviewed 200 cases of gastric carcinoma treated between 1970 and 1980 to assess the value of intestinal metaplasia in the stomach and tumor growth patterns in determining prognosis. Intestinal metaplasia was found to be more frequently associated with early gastric tumors, expanding-type tumors, and tumors located in the antrum. The survival rate was 53% with intestinal metaplasia and 34% without. Sixty-three percent of expanding tumors with metaplasia survived. If the lymph nodes were not involved, the survival rate with metaplasia was 81%. We conclude that intestinal metaplasia and growth patterns are valuable in predicting outcome. Preoperative evaluation of gastric tumors should include multiple endoscopic mucosal biopsy specimens. If intestinal metaplasia is present, the improved possibility of survival should influence the surgeon in the choice of operative treatment.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
