A recent study looked at the correlation between the incidence of cancers and Parkinson’s disease in Taiwan.
The medical study is addressing this correlation for the first time in Eastern Asia. A high number of similar studies have been conducted on Western populations, but never on Easter Asia.
The findings of the study critically point that there are as much as 16 cancer diagnoses that are linked with Parkinson’s disease.
Previous studies contradicted the association between cancer diagnoses and Parkinson’s disease diagnose.
Yet, this recent study underlines that there is a clear link provided by the genetic background of each individual which is an important factor in determining the likelihood for both diseases.
The study relied on data obtained from Taiwan’s National Health Insurance Research Database. Lead researcher Dr. Pan-Chyr Yang from Taiwan’ University College of Medicine compared this data with other medical records at hand.
At the same time, him and his team picked out 62,023 patients that had been diagnosed with Parkinson’s and another 124,046 patients that did not have the disease and constituted the control group.
The first group consisted of patients that had been diagnosed at any time between 2004 and 2010.
Compared to control group, the patients who suffered from Parkinson’s disease presented a higher likelihood to develop 16 of 19 types of cancer comprised in the study. Their hazard ratios ranged from 3.42 to 2.75 in the case of brain cancer, respectively melanoma.
For colorectal cancer, the hazard ratio was calculated at 1.47, while for cervical cancer the hazard ratio was set at 1.36.
The stratification according to age groups also showed that while the risk of being diagnosed with liver cancer increased for both Parkinson’s patients and the control group, the first had a hazard ratio of 2.57.
Also, malignant brain tumors as well as lung cancer did not stand the link with Parkinson’s disease except in the age groups of 60 to 70 and above.
For the rest of patients that had been diagnosed with Parkinson’s, there was no direct link with either breast, thyroid or ovarian cancers.
Nonetheless, the hypothesis that Parkinson’s patients are more predisposed to developing cancers has been proved in 16 out of 19 cancer diagnoses taken into account.
More research is to follow on the genetic correlation between cancers and Parkinson’s.
The findings of the Taiwan study are found in JAMA Oncology Journal.
