The expression of gastrointestinal cancer antigen, CA 19-9, and of carcinoma-associated antigen, CA-50, was studied in formalin-fixed and paraffin-embedded tissue from 18 patients with ulcerative colitis, 29 with Crohn's disease in the colon, four with diverticular disease, and eight with sigmoid volvulus. None of the patients with inflammatory bowel disease showed strong dysplasia or had manifest carcinoma. Both antigens were expressed frequently in patients with inflammatory bowel disease. Of the 18 patients with ulcerative colitis, 17 were positive for both CA 19-9 and CA-50, and of the 29 with Crohn's colitis, 21 were positive for CA 19-9 and 22 for CA-50. No distinct differences in antigenic expression were found between Crohn's disease and ulcerative colitis. CA-50 was expressed in normal colonic mucosa from 10 of 12 patients with sigmoid volvulus or diverticular disease, and such mucosa was positive for CA 19-9 in three of the four patients with diverticular disease and in two of the eight patients with sigmoid volvulus. It is concluded that immunodetection of CA-50 or CA 19-9 is of limited value in the differential diagnosis of inflammatory bowel disease. The usefulness of these antigens as markers for precancerous changes in inflammatory bowel disease is also doubtful, since the expression is also frequent in cases of inflammatory lesions, with no obviously increased risk of malignancy.

Primary mesenteric adenocarcinoma (PMA) is a rare malignant disease. A case of PMA that was covered by an abscess of the mesocolon and intestinal obstruction is reported in the present study. As the onset site of PMA is often obscured or hidden, there may be no clinical symptoms in the early stage. At the advanced stage, the tumor size is large enough to induce intestinal obstruction, perforation, bleeding, volvulus and other clinical symptoms in the majority of patients. Computed tomography scans, ultrasound and other auxiliary examinations are not sufficiently accurate for diagnosing PMA with non-specific characteristics in the majority of cases, causing certain difficulties in the pre-operative diagnosis of PMA, which easily lead to misdiagnosis. The main effective treatment of PMA is surgical resection as early as possible. Thus, when a patient is suspected of having malignancies, and gastrointestinal cancer and other malignancies of the digestive organs may be excluded, the possibility of PMA should be considered.
