Incidence and mortality rates of colorectal cancer in Malaysia
Muhammad Radzi Abu Hassan,Ibtisam Ismail,Mohd Azri Mohd Suan,Faizah Ahmad,Wan Khamizar Wan Khazim,Zabedah Othman,Rosaida Mat Said,Wei Leong Tan,Siti Rahmah @ Noor Syahireen Mohammed,Shahrul Aiman Soel 한국역학회 2016 Epidemiology and Health Vol.38 No.-
OBJECTIVES: This is the first study that estimates the incidence and mortality rate for colorectal cancer (CRC) patients in Malaysia by sex and ethnicity. METHODS: The 4,501 patients were selected from National Cancer Patient Registry-Colorectal Cancer data. Patient survival status was cross-checked with the National Registration Department. The age-standardised rate (ASR) was calculated as the proportion of CRC cases (incidence) and deaths (mortality) from 2008 to 2013, weighted by the age structure of the population, as determined by the Department of Statistics Malaysia and the World Health Organization world standard population distribution. RESULTS: The overall incidence rate for CRC was 21.32 cases per 100,000. Those of Chinese ethnicity had the highest CRC incidence (27.35), followed by the Malay (18.95), and Indian (17.55) ethnicities. The ASR incidence rate of CRC was 1.33 times higher among males than females (24.16 and 18.14 per 100,000, respectively). The 2011 (44.7%) CRC deaths were recorded. The overall ASR of mortality was 9.79 cases, with 11.85 among the Chinese, followed by 9.56 among the Malays and 7.08 among the Indians. The ASR of mortality was 1.42 times higher among males (11.46) than females (8.05). CONCLUSIONS: CRC incidence and mortality is higher in males than females. Individuals of Chinese ethnicity have the highest incidence of CRC, followed by the Malay and Indian ethnicities. The same trends were observed for the age-standardised mortality rate.

Intestinal obstruction: predictor of poor prognosis in colorectal carcinoma?
Mohd Azri Mohd Suan,Wei Leong Tan,Shahrul Aiman Soelar,Ibtisam Ismail,Muhammad Radzi Abu Hassan 한국역학회 2015 Epidemiology and Health Vol.37 No.-
OBJECTIVES: The goal of this study was to assess the relationship between intestinal obstruction and the prognosis of colorectal carcinoma. METHODS: Data pertaining to 4,501 colorectal carcinoma patients were extracted from the national colorec-tal registry and analysed. Survival analysis was performed using the Kaplan-Meier method. The log-rank test was used to compare the survival rate between patients with intestinal obstruction and those without intesti-nal obstruction. The p-values< 0.05 were considered to indicate statistical significance. Simple Cox proportion-al hazards regression analysis was used to estimate the crude hazard ratio of mortality from colorectal cancer. RESULTS: Intestinal obstruction was reported in more than 13% of patients. The 3-year survival rate after treat-ment was 48.3% (95% confidence interval [CI], 43.9 to 52.8) for patients with intestinal obstruction (n= 593) and 54.9% (95% CI, 53.1 to 56.6) for patients without intestinal obstruction (n= 3,908). The 5-year survival rate for patients with intestinal obstruction was 37.3% (95% CI, 31.9 to 42.8), which was lower than that of patients without intestinal obstruction (45.6%; 95% CI, 43.5 to 47.7). After adjusting the hazard ratio for oth-er prognostic variables, intestinal obstruction had a statistically significant negative correlation with the surviv-al rate of colorectal cancer patients, with an adjusted hazard ratio of 1.22 (p= 0.008). CONCLUSIONS: The presence of intestinal obstruction is associated with a lower survival rate among colorectal cancer patients.

Survival Analysis and Prognostic Factors for Colorectal Cancer Patients in Malaysia
Hassan, Muhammad Radzi Abu,Suan, Mohd Azri Mohd,Soelar, Shahrul Aiman,Mohammed, Noor Syahireen,Ismail, Ibtisam,Ahmad, Faizah Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.7
Background: Cancer survival analysis is an essential indicator for effective early detection and improvements in cancer treatment. This study was undertaken to document colorectal cancer survival and associated prognostic factors in Malaysians. Materials and Methods: All data were retrieved from the National Cancer Patient Registry-Colorectal Cancer. Only cases with confirmed diagnosis through histology between the year 2008 and 2009 were included. Retrieved data include socio-demographic information, pathological features and treatment received. Survival curves were plotted using the Kaplan-Meier method. Univariate analysis of all variables was then made using the Log-rank test. All significant factors that influenced survival of patients were further analysed in a multivariate analysis using Cox' regression. Results: Total of 1,214 patients were included in the study. The overall 3- and 5-year survival rates were 59.1% and 48.7%, respectively. Patients with localized tumours had better prognosis compared to those with advanced stage cancer. In univariate analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p=0.001) were found to be predictors of survival. None of the socio-demographic characteristics were found to exert any influence. In Cox regression analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p<0.001) were determined as independent prognostic factors of survival after adjusted for age, gender and ethnicity. Conclusions: The overall survival rate for colorectal cancer patients in Malaysia is similar to those in other Asian countries, with staging at diagnosis, primary tumor size, involvement of lymph node and treatment modalities having significant effects. More efforts are needed to improve national survival rates in future.
