Abstract

The incidence of colorectal and small bowel cancers associated with CD development is often accompanied by chronic active inflammation at the site. Although the duodenum can be accessed easily during endoscopy, it is challenging to diagnose malignant transformation prior to the surgery. Early diagnosis of CD-associated cancers is necessary.

Introduction

Case Report

A 55-year-old woman was treated for Crohn's disease (CD) for more than 30 years. Ten years ago, she was diagnosed with duodenal stenosis related to CD on the distal side of the vater papilla, 3 cm in the descending duodenum. Biopsy results from the proximal stricture showed inflammatory changes. Endoscopy performed 5 years later revealed redness immediately proximal to a high-grade obstruction of the descending duodenum (Figure 1). Biopsy of the lesion confirmed adenocarcinoma. Chronic inflammation was present at the cancer site, and the boundary between neoplastic and non-neoplastic lesions was unclear. Additionally, a transnasal endoscope was passed through the 1 cm long stenosis, and no other abnormalities were found in the mucosa distal to the stenosis. The patient then underwent a duodenopancreatectomy. Postoperative pathological examination revealed that the lesion was 0-IIc, tub2 > por2, pT1a(M), ly0, v0, pPM0, pRM0, pN0, and p0 (Figure 2). In addition, this examination revealed high-grade adenoma discontinuously adjacent to intramucosal cancer (Figure 3: yellow line), and immunohistochemical analysis detected p53 [removed]Figure 4).

Discussion

Studies show that the incidence of colorectal and small bowel cancers associated with CD is higher than in the general population due to CD onset at a relatively young age and prolonged duration of the disease[1,2]. Cancer development is often accompanied by chronic active inflammation at the site, and thus it is hypothesized that chronic inflammation of the intestinal tract is closely related to carcinogenesis. Moreover, dysplasia, overexpression of p53 at an early stage, and cancer complications are observed in ulcerative colitis, but the relationship is not clear [3].

Conclusion

The majority of cancers occur in the large intestine, and although the absolute number of small intestinal cancers is small, the relative risk is remarkably high [4]. Upper gastrointestinal tract involvement in CD has been reported to occur in 0.1% of patients with CD [5]. Although the duodenum can be accessed easily during endoscopy, it is challenging to diagnose malignant transformation prior to the surgery because of the presence of chronic inflammation in the background of the cancer site. Many studies report cases of advanced cancer at the time of detection, such as stage IV or lymph node positive cases. Our study suggests that progressive duodenal narrowing and ulceration should be followed up with a careful endoscopic evaluation and biopsy to exclude malignant degeneration of CD. Therefore, early diagnosis of CD-associated cancers is necessary.
