Background: Colorectal cancer (CRC) is the second most common cancer in Malaysia (13.2%). Aim: To study the epidemiologic trend of colorectal cancer in Malaysia and to suggest the strategy in reducing the incidence of CRC in Malaysia. Methods: Total of 13,693 cases of colorectal cancer diagnosed in 2007-2011 were extracted from the Malaysian National Cancer Registry (MNCR). MNCR is a population-based cancer registry which collects data from all government and private facilities (hospitals, clinics, laboratories, National Registration Department and Health Informatics, MOH) by passive notification and active case findings. The registry registers all new cancer cases among Malaysian citizen diagnosed in Malaysia into CanReg4 software. Data were explored using IARC tools and analyzed using CanReg4 software. Results: 55.8% of the colorectal cancer cases were in male and 44.2% in female. ASR was 14.6 per 100,000 population for male and 11.1 per 100,000 populations for female. The male to female ASR ratio was 1.3:1. The 5-years trend shows increasing incidence for both gender. The age-specific incidence rates of the cases were between 45 to 75 years old. The lifetime risk for males was 1 in 56 and in females was 1 in 74. Majority of the cancer were detected among Chinese followed by Malays and Indians. 66% of the colorectal cancer presented at advanced stage (stage 3 and 4) in males and 65% in female. Conclusion: The trend of colorectal cancer is increasing in Malaysia and most of the cancer cases were diagnosed at late stage. To increase the detection rate of CRC at early stage, Ministry of Health Malaysia has introduce screening program using immunochemical fecal occult blood test (iFOBT) since 2013. Tremendous campaigns also being carry out in the community to create awareness on the importance of colorectal cancer screening for early detection and treatment hence improved the survival.
