Abstract

A cancer cluster can be defined as a higher-than-expected incidence of cancer in a specific group in a particular geographical space over a period of time [2]. [...]in this study, we used statistical methods to primarily investigate whether the cancer incidence in the village was higher than that of the general Korean population when the factory was in operation (2001–2017) and whether living in the village was associated with a higher cancer risk. Materials and methods Collecting national data In early 2018, when the study began, the plant had already closed down, and many of the cancer patients had passed away. [...]carrying out a direct survey was not feasible. From the obtained data, we estimated the mid-year population numbers for each year from 2010 to 2017. Since we wanted to estimate SIRs from 2001 to 2009, we adopted the village population structure from 2001 to 2008 by deducting 5 years from the demographic structure of 2009. In South Korea, the whole population is enrolled in one central insurer, NHIS. Since NHIS enrollment is mandatory, through the insurance system, we could obtain the qualification database of the service (income level, resident area, etc.) and medical treatment databases (date of visit, ICD code, prescription, etc.) of all Hamra-myeon residents including Jang-jeom villagers and reconstruct a detailed cohort at an individual level [3].
