A Multidisciplinary Study of Parkinson’s

Disease to Analyze the Relationship with

the Onset and Cancer and Cardiovascular

Disease

 

 

Patients with Parkinson’s Disease Are Reported to Have a

 

Significantly Lower Overall Cancer Incidence Rate but at Greater

 

Risk of Skin Cancer and Cardiovascular Disease

 

 

A multidisciplinary research team of Korea University Ansan Hospital

 

(Professor Joo-Hyun Park and Professor Do-Hoon Kim of Department of

 

Family Medicine, Professor Do-Young Kwon of Department of Neurology,

 

Professor Hwa Jung Ryu of Department of Dermatology, Professor Kyung-do

 

Han of Department of Statistics and Actuarial Science of Soongsil University)

 

analyzed the incidence and prevalence rate of Parkinson’s disease in Korea and

 

its correlation with cancer and cardiovascular disease through a cohort study

 

using the national health insurance’s national health information.

 

 

Parkinson’s disease causes tremor and muscle stiffness due to the loss of

 

dopamine, neurotransmitter, because of the degeneration of neurons in the

 

substantia nigra in the brain. According to the analysis of Parkinson’s disease in

 

Korea from 2010 to 2015, the prevalence rate and incidence rate of women were

 

60% and 40% respectively, higher than that of men. Especially since 2013, the

 

increase was worsening. The analysis shows that change in perception about

 

patients with Parkinson’s disease and management is needed.

 

 

There is a lot of controversy over the incidence rate of cancer in patients with

 

Parkinson’s disease. According to a study on Americans and Europeans

 

analyzing the correlation between Parkinson’s disease, a degenerative disease,

 

and cancer, a proliferative disease, cancer risk was lower for patients with

 

Parkinson’s disease than the general population. However, a recent study on

 

Taiwanese reported that the incidence rate of cancer in patients with Parkinson’s

 

disease was higher, stirring controversy. Because economic status and genetic

 

characteristics differ, a Korean-specific study was conducted.

 

 

As a result of a follow-up of 2,022,852.6 person-years of Parkinson’s patients in

 

Korea, the overall risk of cancer was significantly lower than that of the general

 

population. For almost all kinds of cancer including laryngeal cancer, stomach

 

cancer, colorectal cancer, liver cancer, pancreatic cancer, lung cancer, the risk

 

was lower by up to 50%, but in a skin cancer study that was co-conducted,

 

incidence risk of melanoma, malignant skin cancer, was 2.8 times higher for

 

men over 65 years old, and 1.3 times higher for women over 65 years old,

 

signifying the importance of paying attention to elderly patients with

 

Parkinson’s disease for developing melanoma.

 

 

In a study investigating the relationship with major cardiovascular disease,

 

another big cause of death for the elderly population along with Parkinson’s

 

disease which is a degenerative condition, patients with Parkinson’s disease had

 

a 43% increase in the risk of myocardial infarction, 42% increase in the risk of

 

stroke, and 65% increase in the risk of heart failure, demonstrating the

 

importance of not only the management of Parkinson’s disease but also the

 

management of a cardiovascular disease.

 

 

The research team’s papers were published in world’s best journals such as

 

Circulation (5-year Impact Factor of 20.47, top 0.37% of JCR), European

 

Journal of Cancer (5-year Impact Factor of 6.73, top 10.2% of JCR), Journal of

 

the European Academy of Dermatology and Venereology (5-year Impact Factor

 

of 4.15, top 9.8% of JCR), BMC Geriatrics (5-year Impact Factor of 3.458, top

 

38.7% of JCR), proving the team’s excellence.

 

 

“The study analyzed the correlation between Parkinson’s disease and various

 

diseases based on the data containing all Parkinson’s disease patients who are

 

registered as a rare incurable disease in the National Health Insurance Service

 

with multiple departments such as Family Medicine, Neurology, and

 

Dermatology,” Korea University Ansan Hospital research team participating in

 

the study said. “Unlike previous studies, this study was conducted on Koreans

 

so it could be applicable in patient-specific treatment and management for

 

dementia in Korea.”
