AbstractAbstract PDF
Objectives
The aim of this study was to determine the factors associated with the spatial distribution of the incidence of colorectal cancer (CRC) in the neighborhoods of Tehran, Iran using Bayesian spatial models.
Methods
This ecological study was implemented in Tehran on the neighborhood level. Socioeconomic variables, risk factors, and health costs were extracted from the Equity Assessment Study conducted in Tehran. The data on CRC incidence were extracted from the Iranian population-based cancer registry. The Besag-York-Mollié (BYM) model was used to identify factors associated with the spatial distribution of CRC incidence. The software programs OpenBUGS version 3.2.3, ArcGIS 10.3, and GeoDa were used for the analysis.
Results
The Moran index was statistically significant for all the variables studied (p<0.05). The BYM model showed that having a women head of household (median standardized incidence ratio [SIR], 1.63; 95% confidence interval [CI], 1.06 to 2.53), living in a rental house (median SIR, 0.82; 95% CI, 0.71 to 0.96), not consuming milk daily (median SIR, 0.71; 95% CI, 0.55 to 0.94) and having greater household health expenditures (median SIR, 1.34; 95% CI, 1.06 to 1.68) were associated with a statistically significant elevation in the SIR of CRC. The median (interquartile range) and mean (standard deviation) values of the SIR of CRC, with the inclusion of all the variables studied in the model, were 0.57 (1.01) and 1.05 (1.31), respectively.
Conclusions
Inequality was found in the spatial distribution of CRC incidence in Tehran on the neighborhood level. Paying attention to this inequality and the factors associated with it may be useful for resource allocation and developing preventive strategies in atrisk areas.

AbstractAbstract PDF
Objectives

Screening for colorectal cancer is considered cost effective, but is underutilized in the U.S. Information on the efficiency of "tailored interventions" to promote colorectal cancer screening in primary care settings is limited. The paper reports the results of a cost effectiveness analysis that compared a survey-only control group to a Centers for Disease Control (CDC) web-based intervention (screen for life) and to a tailored interactive computer-based intervention.

Methods

A randomized controlled trial of people 50 and over, was conducted to test the interventions. The sample was 1224 partcipants 50-70 years of age, recruited from Kelsey-Seybold Clinic, a large multi-specialty clinic in Houston, Texas. Screening status was obtained by medical chart review after a 12-month follow-up period. An "intention to treat" analysis and micro costing from the patient and provider perspectives were used to estimate the costs and effects. Analysis of statistical uncertainty was conducted using nonparametric bootstrapping.

Results

The estimated cost of implementing the web-based intervention was $40 per person and the cost of the tailored intervention was $45 per person. The additional cost per person screened for the web-based intervention compared to no intervention was $2602 and the tailored intervention was no more effective than the web-based strategy.

Conclusions

The tailored intervention was less cost-effective than the web-based intervention for colorectal cancer screening promotion. The web-based intervention was less cost-effective than previous studies of in-reach colorectal cancer screening promotion. Researchers need to continue developing and evaluating the effectiveness and cost-effectiveness of interventions to increase colorectal cancer screening.

AbstractAbstract PDF
OBJECTIVES
Effective cancer prevention and control measures can only be done when dependable data on the cancer incidence is available. The Seoul Cancer Registry (SCR) was founded to provide valid, comparable and representative cancer incidence data for Koreans. We aimed to compare the cancer incidence in the first (1993-1997) and second term (1998-2002) of the SCR, and we analyzed the annual incidence trend during that 10 years. METHODS: The SCR detects potential cancer cases through the Korean Central Cancer Registry (KCCR) data, the health insurance claims, the individual hospital's discharge records and the death certificates. About 87% of the SCR data is registered through the KCCR. The rest of the data is registered by SCR registrars who visit about 70~80 mid-sized hospitals in Seoul to review and abstract the medical records of the potential cancer patients. RESULTS: The total number of new cancer cases was higher in 1998~2002 than in 1993~1997 by 20.6% for men and 18.4% for women, respectively. The age-standardized rate (ASR) of total cancer per 100,000 increased 1% (from 295.4 to 298.3) for men and 5.1% (from 181.5 to 190.7) for women, between the two periods. The commonest cancer sites during 1998-2002 for men were stomach, liver, bronchus/lung, colorectum, bladder and prostate, and the commonest cancer sites for women were breast, stomach, colorectum, cervix uteri, thyroid and bronchus/lung. Compared with the ASRs in 1993, the ASRs in 2002 increased for colorectum (58.4% for men, 27.1% for women), prostate (81.5%), breast (58.3% for women), thyroid (141% for women), and bronchus/lung (15.4% for women). The ASRs for stomach (-18.7% for men, -20.7% for women) and uterine cervix cancer (-39.7%) had decreased. CONCLUSIONS: The cancer incidence is increasing in Seoul, Korea, especially for the colorectum and prostate for men, and for the breast, colorectum, bronchus/lung and thyroid for women.

AbstractAbstract PDF
Nationwide incidence survey was conducted to estimate the annual incidence rates of colorectal cancer among Koreans between Jan 1, 1988 and Dec 31, 1989. The population of the incidence survey was the beneficiaries of Korea Medical Insurance Corporation(KMIC), Which were about 4,500,000 persons. The medical records of patients with diagnosis of either ICD-9 153(colon cancer), 154(rectal caner), 197(secondary malignat neoplasm of digestive and respiratory system), or 211(benign neoplasm of digestive system) were abstracted for the period with the standard format. The diagnosis was confirmed by one oncologist through the review of these abstracts. The numerator of the rate was finally defined as the incident colorectal cancer cases diagnosed between July 1, 1988 and June 30, 1989. The crude annual incidence of colorectal cancer for men was 13.1 per 100,000 and 10.6 for women, which was still low when compared with those of Japan and China during the same period. Age-adjusted sex ratio was 1.2 for fight-sided colon cancer and 1.9 for left-sided colon cancer. The excess of right colon cancer among postmenopausal women was remarkable, so further analytical approach would be needed to investigate which factors are related with this phenomenon.

AbstractAbstract PDF
OBJECTIVES
The incidence of colorectal cancer increased greatly among the elderly in Korea, but the relationship between smoking and colon cancer remains controversial. Few studies have targeted Asian elderly people. We analyzed the smoking status, the amount smoked, and the smoking duration as risk factors of colorectal cancer to determine their association and causality. METHODS: The cohort members (n=14,103) consisted of 4,694 males and 9,409 females, and they were derived from the Korea Elderly Phamacepidemilogic Cohort (KEPEC), which was a population-based dynamic cohort. They were aged 65 years or more and they lived in Busan Metropolitan City between from 1993-1998; they were beneficiaries of the Korean Medical Insurance Corporation (KMIC). The baseline information was surveyed by a selfadministered mailed questionnaire; after 8.7 person-years of mean follow up period, 100 cases of colorectal cancer occurred. The adjusted relative ratio (aRR) of smoking status, the smoking amount and the smoking duration were calculated from the Cox's proportional hazard model with the never-smokers as a reference group and the Cox model controlled for age, gender, precancerous lesions of CRC, medication history of NSAIDs and antibiotics, the alcohol drinking status and BMI. RESULTS: Compared with the never smokers, the aRRs were 2.03 (95% CI=1.02-4.03) and 1.36 (95% CI=0.80-2.32) for the ex-smokers and current smokers, respectively. Statistical significant trends were not observed for the dose-relationship among the elderly, either for the mean daily amount smoked (p for trend=0.28) or for the total amount (p for trend=0.15). Still, the aRRs were 1.51 (95% CI=0.97-2.34) for the elderly who smoked less than 40 years and 2.35 (95% CI=1.16-4.74) for the elderly who had 40 years or more of smoking (p for trend=0.06). Smokers who started smoking before the age 20 had an increased aRR of 2.15 (95% CI=1.17-3.93) compared to the never smokers. CONCLUSIONS: After controlling for age, gender, precancerous lesion of CRC, medication history of NSAIDs and antibiotics, the alcohol drinking status and BMI, smoking increases the risk of colorectal cancer among elderly people. The age when starting smoking is also important.
