BACKGROUND/AIMS: This study aimed to determine the epidemiological characteristics of @entity14 in @entity233 . MATERIALS AND METHODS: In this multicenter, prospective, and cross-sectional registry study, data for 968 @entity1 with @entity14 from 21 centers in 7 geographic regions were analyzed. RESULTS: Diagnosis was @entity694 in 662 (68.4%) and @entity188 in 306 (31.6%) @entity1 . In total, 60.9% of @entity1 was male; mean age was 58.9  12.6 years. Among @entity1 , 15.0% was drinking @entity167 , 17.5% was smoking, 1.5% had familial history of @entity1412 , 15.0% had @entity6 , 1.0% had @entity29 . Fruit and vegetable consumption was low (<3 times/week) in 35.5% and red meat consumption was high (>= 3 times/week) in 47.4% of the @entity1 . Median time-to diagnosis was 3.0 months and 4.0 months for @entity1 with @entity694 , respectively. Mean body mass index was >25 in all group of @entity1 . Distal rectum (61.3%) and sigmoid colon (36.8%) were the most common locations of @entity5 , for rectum and colon respectively. In total, 85.6% of @entity1 were operated; 25.8% had emergency surgery. Low anterior resection rate was 64.2% in @entity188 . In majority (89.8%) of the @entity1 with @entity188 who received preoperative treatment, conventional chemo-radiotherapy regimen was given. pTNM staging at diagnosis showed that stage III and IV @entity1 were in majority (35.9% and 29.7%, respectively). CONCLUSION: @entity694 is more frequent than @entity188 in @entity233 . @entity14 @entity1 are diagnosed at later stages. Most of the cases were operated. Interregional differences for risk factors are worthwhile for evaluation in future trials.
