Background: Although a high socioeconomic status (SES) was considered as an established risk factor for melanoma in western countries and areas, there was limited evidence of the association between SES and melanoma in China. Methods: We studied prospectively enrolled primary melanoma patients at Zhongshan Hospital, Fudan University over a period of 5 years between January 2013 to December 2017. The clinical stage at diagnosis was categorized according to Guidelines of Chinese Society Oncology, Melanoma.

Patients with low education level (middle school and below) and low monthly household income (<3000CNY) were associated with a greater risk of melanoma. Similar results were indicated f...Continue Reading
