A systematic review on the effectiveness and costeffectiveness
of Immunochemical faecal occult IFOBT for
CRC screening was carried out. A total of 450 relevant titles
were identified, 41 abstracts were screened and 18 articles
were included in the results. There was fair level of
retrievable evidence to suggest that the sensitivity and
specificity of IFOBT varies with the cut-off point of
haemoglobin, whereas the diagnostic accuracy performance
was influenced by high temperature and haemoglobin
stability. A screening programme using IFOBT can be
effective for prevention of advanced CRC and reduced
mortality. There was also evidence to suggest that IFOBT is
cost-effective in comparison with no screening, whereby a
two-day faecal collection method was found to be costeffective
as a means of screening for CRC. Based on the
review, quantitative IFOBT method can be used in Malaysia
as a screening test for CRC. The use of fully automated
IFOBT assay would be highly desirable.

OBJECTIVES: This study explored the demographic characteristics of hepatitis C patients in the Kota Setar (KS) district, Kedah, Malaysia, the prevalence of intravenous drug use (IVDU) as a risk factor among these patients, and the associations between IVDU and demographic characteristics. METHODS: Retrospective data pertaining to 713 patients from January 2009 to December 2013 were retrieved from hospital and disease notification records for analysis. The risk factors for hepatitis C virus (HCV) infection were grouped into IVDU and non-IVDU risk factors for analysis using multiple logistic regression. RESULTS: Of the hepatitis C patients included in this study, the most common age group was 31 to 40 years (30.2%), and male patients (91.2%) made up the overwhelming majority. Ethnic Malays constituted approximately 80.4% of the patients, and IVDU was the main risk factor (77.8%) for HCV infection. Multiple logistic regression showed that male patients were 59 times more likely to have IVDU as a risk factor for HCV infection. Single patients were 2.5 times more likely to have IVDU as a risk factor. Patients aged > or =71 years were much less likely than patients aged < or =30 years to have IVDU as a risk factor for HCV infection. CONCLUSIONS: IVDU was found to be an important risk factor for HCV infection among patients in the KS district. The factors associated with IVDU included age, sex, and marital status. Appropriate preventive measures should be developed to target the groups in which IVDU is most likely to be a risk factor for HCV infection.

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 colorectal 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 intestinal obstruction. The p-values<0.05 were considered to indicate statistical significance. Simple Cox proportional 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 treatment 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 other prognostic variables, intestinal obstruction had a statistically significant negative correlation with the survival 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.

comprehensive overview of chronic hepatitis C (CHC)management.1 The author highlighted the concern over theexorbitant cost of direct-acting antivirals, which is the reason for their limited use in Malaysia currently. Based on the findings of the previous studies, the author also underlined that Asians receiving the conventional, interferon-based treatment generally have a higher sustained virological response (SVR) rate as compared with Caucasians and African Americans, mainly due to the interleukin-28B (IL28) single nucleotide polymorphism (SNP) across different ethnic populations. Nonetheless, to date, information on the variations in IL-28 genotypes among different ethnic groups in Malaysia is still limited.

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.

Objective: To identify the predictors of mortality among in-hospital melioidosis patients. Methods: A total of 453 patients in Hospital Sultanah Bahiyah, Kedah, and Hospital Tuanku Fauziah, Perlis with culture-confirmed melioidosis were retrospectively included in the study. Advanced multiple logistic regression was used to obtain the final model of predictors of mortality from melioidosis. The analysis was performed using STATA/SE 14.0. Results: A total of 50.11% (227/453) of the patients died at the hospital, and a majority (86.75%, 393/453) of cases were bacteremic. The logistic regression estimated that the bacteremic type of melioidosis, low platelet count, abnormal white blood cell counts, and increased urea value were predictors of mortality. The results showed that bacteremic melioidosis increased the risk of death by 4.39 times (OR 4.39, 95% CI 1.83-10.55, P=0.001) compared to non-bacteremic melioidosis. Based on laboratory test, the adjusted ORs from the final model showed that all three blood investigations were included as the associated factors of mortality for the disease [high white blood cell (>10×109/L): OR 2.43, 95% CI 1.41-4.17, P<0.001; low white blood cell (<4×109/L): OR 3.82, 95% CI 1.09-13.34, P=0.036; low platelet (<100×109/L): OR 4.19, 95% CI 1.89-9.30, P<0.001; high urea (>7 800 μmol/L): OR 5.53, 95% CI 2.50-12.30, P<0.001; and low level of urea (<2 500 μmol/L): OR 3.52, 95% CI 1.71-7.23, P=0.001). Conclusions: Routine blood investigations during a hospital admission can early identify predictors of mortality in melioidosis patients.

Introduction: Colorectal cancer (CRC) is the second most
common cancer in Malaysia with 65% detected at stage III
and IV. Despite the increasing incidence of cancers
including CRC, Malaysia has yet to implement populationbased screening for cancers. The objective of this paper is
to review the strategic planning and implementation of the
CRC screening program in Malaysia.
Methods: A desk review was conducted from August to
October in 2018, to examine, review and describe the
historical perspective, strategic planning and
implementation of the current CRC screening program in
Malaysia.
Results: The main policy documents related to CRC
screening are the National Strategic Plan for Cancer Control
Programme 2016-2020, the Clinical Practice Guideline for
Management of Colorectal Carcinoma 2017, and the
Implementation Guideline for CRC Screening in Malaysia
2014. Several papers have been published on the
epidemiology of CRC in Malaysia. Between 2014 and 2018,
127,957 men and women were screened using
immunochemical Faecal Occult Blood Test (iFOBT); 9.3%
had positive iFOBT results and were referred for
colonoscopy. For those who underwent colonoscopy, CRC
detection rate was 4.1% and 13.9% for pre-malignant
conditions. Barriers were identified along the continuum of
screening process, including patient, provider, and system
factors.
Conclusion: Although population-level organised screening
programmes are preferable to opportunistic screening, the
CRC programme in Malaysia was tailored to meet the needs
of the population based on available existing resources. A
well-mapped budget for the entire screening programme
continuum, a strong partnership between stakeholders and
an opportunistic screening strategy is crucial to address the
rising incidence of CRC

The downstream effect of the pandemic on global cancer prevention and control efforts is wide-ranging, especially
for lower and middle-income countries (LMICs), including Malaysia. This paper explores the performance of the colorectal cancer screening programme in Malaysia for the years 2019 and 2020, This is followed by evidence-based
recommendations for building back a better cancer control programme in Malaysia. Malaysia screened a total of
31,529 eligible candidates in 2019 and 42,554 in 2020. A total of 2,668 (8.46%) and 2767 (6.50%) individuals tested
positive for the immunochemical faecal occult blood test (iFOBT) in 2019 and 2020 respectively. Of these numbers,
only 1454 (54.49%) of those who tested positive underwent colonoscopy in 2019 and this proportion reduced to
1148 (41.48%) in 2020. This analysis also shows a drop in the number of screenings in the second quarter of 2020.
This drop coincides with the announcement of Malaysia’s first Movement Control Order. Existing challenges exacerbated by pandemic restrictions have possibly led to a decreased colonoscopy attendance rate in 2020. To build
back a better cancer control programme, better governance, and political will, coupled with improved financing,
sustainable partnerships, improved service delivery, and a robust monitoring and evaluation mechanism is vital.
