Objective: The aim of this study was to evaluate whether there is an association between Parkinson’s disease (PD) and colorectal cancer in Taiwan. Methods: This was a case-control study using claim data of the Taiwan National Health Insurance Program. There were 64,619 subjects aged 20-84 with newly diagnosed colorectal cancer as cases and 64,619 randomly selected subjects without colorectal cancer as controls from 2005 to 2011. Both cases and controls were matched by sex, age, comorbidities, and index year of diagnosing colorectal cancer. Subjects who were diagnosed with PD within 5 years of diagnosing colorectal cancer were excluded. The multivariable logistic regression model was used to estimate the adjusted odds ratio (OR) and 95% confidence interval (95% CI) for risk of colorectal cancer associated with PD. Results: After adjusting for confounding factors, the multivariable logistic regression analysis revealed that the adjusted OR of colorectal cancer was 0.69 for subjects with PD more than 5 years before index date (95% CI 0.59, 0.81), as compared with subjects without PD. Conclusion: PD is associated with reduced odds of colorectal cancer. Further research is needed to elucidate the mechanisms underlying our findings.

Background: The aim of this study was to investigate whether there is a relationship between Parkinson’s disease and pancreatic cancer in Taiwan. Methods: This was a case-control study using claim data of the Taiwan National Health Insurance Program. There were 13,861 subjects aged 20- 84 with newly diagnosed pancreatic cancer as cases and 55,444 randomly selected subjects without pancreatic cancer as controls from 1998 to 2011. Cases and controls were matched by sex, age and index year of diagnosing pancreatic cancer. The association of pancreatic cancer with Parkinson’s disease was evaluated by the multivariable logistic regression model to estimate the adjusted odds ratio (OR) and 95% confidence interval (95% CI). Results: After adjusting for confounding factors including acute pancreatitis, chronic pancreatitis, diabetes mellitus, biliary stone, alcoholism, hepatitis B and hepatitis C, the multivariable logistic regression analysis showed the adjusted OR of pancreatic cancer was 0.82 for subjects with Parkinson’s disease (95% CI 0.55, 1.21), as compared with subjects without Parkinson’s disease. Conclusion: No association is detected between Parkinson’s disease and pancreatic cancer.

INTRODUCTIONThe purpose of this study was to explore whether diabetes mellitus (DM) correlates with the risk of kidney cancer in Taiwan.

MATERIALS AND METHODSWe designed a population-based case-control study from the Taiwan National Health Insurance Database, which consisted of 116 patients with newly diagnosed kidney cancer as cases and 464 subjects without kidney cancer as controls in 2000 to 2009. Both cases and controls were aged ≥20 years. Baseline comorbidities were compared between kidney cancer cases and controls.

RESULTSMultivariable analysis showed no association was detected between DM and kidney cancer (OR 1.06, 95% CI, 0.58 to 1.94). Hypertension (OR 2.05, 95% CI, 1.23 to 3.42), chronic kidney diseases (OR 2.57, 95% CI, 1.23 to 5.37), cystic kidney diseases (OR 18.6, 95% CI, 1.84 to 187.6) and kidney stones (OR 4.02, 95% CI, 2.43 to 6.66) were significant comorbidities associated with increased risk of kidney cancer. Use of alpha-glucosidase inhibitor was associated with increased risk of kidney cancer (OR 4.31, 95% CI, 1.07 to 17.3).

CONCLUSIONDM does not correlate with the risk of kidney cancer. Hypertension, chronic kidney diseases, cystic kidney diseases, kidney stones and use of alpha-glucosidase inhibitors are associated with kidney cancer.
