PURPOSE: Behcet's disease (BD) is rarely reported to be associated with malignancies in the literature. However, the frequency of cancer in BD patients remains unknown. This study evaluated cancer morbidity in BD patients compared with that in the general population of Korea. MATERIALS AND METHODS: A retrospective chart review was performed on 506 patients visiting our hospital from 1994 to 2011 for BD. We analyzed the standardized morbidity rate (SMR), which is the ratio of observed to expected malignancies. Furthermore, we reviewed cases of solid cancer in BD patients in the literature. RESULTS: Of the 506 patients with BD, 11 (2.17%) developed cancer. We found a variety of solid cancers without predominance and no hematologic malignancies. The total number of cancers observed was less than expected, which was determined from the statistical data of the National Cancer Information Center of Korea, with an SMR of 0.023 (95% confidence interval, 0.012-0.039). CONCLUSION: BD may be associated with a lower cancer-related morbidity compared with the general population of Korea.

BACKGROUND/AIMS: Anemia in patients with inflammatory bowel disease significantly affects the quality of life. The aim of this study was to investigate the frequency of and risk factors for anemia and to describe the management of anemia in patients with intestinal Behcet's disease (BD) in actual clinical practice. METHODS: We included 64 patients with intestinal BD who visited the outpatient clinic of a tertiary referral center in June 2011 and had available laboratory data for the subsequent 6 months. RESULTS: Anemia was detected in 26 patients (40.6%). After 6 months, anemia was still present in 14 of these patients (53.8%). The cause of anemia was investigated in eight patients (30.8%), and oral iron supplementation was prescribed to four patients (15.4%). Of these four patients, two (50%) recovered completely within 6 months. Anemia was associated with a high Disease Activity Index for Intestinal Behcet's Disease (DAIBD, p=0.024), erythrocyte sedimentation rate (p=0.003), and C-reactive protein (p=0.049) in univariate analysis. In multivariate analysis, the factor predictive for anemia in patients with intestinal BD was a higher DAIBD (> or =40; odds ratio, 4.08; 95% confidence interval, 1.21 to 13.71; p=0.023). CONCLUSIONS: Although anemia is common in intestinal BD patients, its clinical importance is overlooked in daily practice. Moderate to severe disease activity is predictive of anemia.
