title: Association of colorectal carcinoma with metabolic diseases; experience with 138 cases from Kelantan, Malaysia.
abstract: OBJECTIVE
  Kelantan in Malaysia has a high prevalence of diabetes and colorectal cancer is also on the rise. This study is to determine the association of metabolic diseases, particularly diabetes type 2 [DM2] and hypertension, with colorectal cancer patients in our population.
  
  
  METHODS
  This retrospective study was conducted on all colorectal carcinomas in Hospital Universiti Sains Malaysia (HUSM) in Kelantan from ythe ears 2001-2006. The data were retrieved from the Registry in Pathology laboratory and the clinical details from the patients' clinical records and analyzed using SSPS Version 12.0, with a value of p<0.05 taken to be statistically significant.
  
  
  RESULTS
  138 CRC cases with complete clinical records were included. The age ranged from 16.0 to 88.0 years, with a mean of 56.9 -/+ SD 15.4. The male 90(65%) to female 48(35%) ratio was 1.7:1.0 and 47.8% were suffering from metabolic diseases; 18(13.0%) with Diabetes Mellitus Type 2(DM2), and 48(34.8%) with hypertension (HT). Diabetes Type 2 and hypertension also demonstrated significant association (p<0.05) with the stage and the site of the cancer. Patients with diabetes type 2 88.8%(16/18) and Hypertension 85.4% (41/48) were strongly associated with cancers located in the distal to transverse colon (p<0.001).
  
  
  CONCLUSIONS
  There is a high proportion of metabolic diseases; hypertension and diabetes type 2 among colorectal carcinomas seen in Kelantan population. In this preliminary study we noted a strong association of metabolic diseases with the stage and site of the cancer. To reduce CRC incidence, the high prevalence of DM2 in Kelantan needs to be addressed.
