QJM, May 1, 2003; 96(5): 345 - 353
Results: "Clinico-pathological data were ascertained for 395 cases, including 175 adenocarcinomas, 107 lymphomas and 79 carcinoid tumors. In 13% of adenocarcinoma cases and in 39% of lymphomas, there was a diagnosis of celiac disease. Survival rates at 30 months for adenocarcinomas, lymphomas and carcinoid tumors were 58%, 45% and 78%, respectively. Prognosis of all tumors was inversely related to stage at presentation, and lymphomas associated with celiac disease were associated with a poorer prognosis."
This study provides more evidence that those with celiac disease run a greater risk of getting adenocarcinoma of the small bowel, as well as lymphoma. Because of the high rate of metastatic disease in the patients studied, there appears to be a long time from the onset of symptoms to diagnosis, which is a concern.
Unfortunately this study does not address when celiac disease was diagnosed in these patients, and whether or not they were treating it with a gluten-free diet. Other studies have shown that cancer risk decreases to that of the normal population in patients who are on a gluten-free diet for at least five years.
