OBJECTIVES Using the population-based cancer registry in Jejudo, we found that Jejudo had lower incidence in stomach cancer than other regions in Korea. The aim of this study was to evaluate reasons for this difference. METHODS: Citrus is the leading agricultural production in Jejudo, suggesting that lower cancer incidence in Jejudo could be explained by citrus fruit intake. We evaluated this hypothesis with quantitative systematic review (QSR). RESULTS: Stomach cancer incidence was significantly lower, with a summary odds ratio (SOR) after QSR of 0.72 [95% CI=0.64-0.81]. In addition, the SOR of pancreatic cancer tended to be lower at 0.83 [95% CI=0.70-0.98]. The SOR of prostate cancer was slightly higher at 1.03 [0.89-1.19]. CONCLUSIONS: Quantitative systematic reviews for the effect of citrus fruit intake on cancer occurrence suggested that lower cancer incidence in Jejudo could be explained by intake of citrus fruits.

OBJECTIVES The purpose of this systematic review was to investigate the association between dietary intake of citrus fruits and prostate cancer risk. METHODS: Authors searched electronic databases and the reference lists of publications of diet and prostate cancer studies until August 2007. All of the epidemiological studies that obtained individual data on dietary intake of citrus fruits and presented risk estimates of the association between intake of citrus fruits and risk of prostate cancer were identified and included. Using general variance-based methods, study-specific odds ratios (OR)/ relative risk (RR) and associated confidence interval (CI)/ standard error (SE) for highest versus lowest intake of citrus fruits level were extracted from each paper. RESULTS: Eleven articles including six case-control studies, one nested case-control study and four cohort studies, proved eligible. Overall summary OR using random effect model did not show an association in risk of prostate caner with intake of citrus fruits (summary OR=1.03, 95% CI=0.89-1.19) with large heterogeneity across studies that we were unable to explain (I(2)=67.88%). The summary ORs in case-control studies and cohort studies were 1.10 (95% CI=0.97-1.22) and 1.05 (95% CI=0.96-1.14), respectively. CONCLUSIONS: Pooled results from observational studies did not show an association between intake of citrus fruits and the risk of prostate cancer, although results vary substantially across studies.

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.
