Basal and squamous cell carcinoma (BCC, SCC), collectively referred to as keratinocyte-derived skin cancer (KC), are the most common human cancers worldwide. Surgery is the treatment of choice, but may represent overtreatment in the very elderly. This study aims to address this issue by investigating the life expectancy of patients over 80 years after surgery.
A single-center, retrospective study was performed to include surgically treated KC patients at the Department of Dermatology and Venereology of the University Hospital in St. Pölten, Austria, between 01.01.2011 and 31.12.2017, who were 80 years or older. Data on individual survival (cut-off April 30, 2020), date and cause of death were retrieved from the Austrian national demographic database at Statistics Austria (Vienna).
940 patients (450 female, 490 male, 639 BCCs, 301 SCCs) were included with 307 being alive at the cut-off date. Median postoperative survival was 57 months (95% CI, 54-63 months).
With a median postoperative survival of almost 5 years, surgery remains a valid treatment option for KC at the end of life. However, 77 of the treated patients died within a year after surgery and preoperative assessment might have helped to avoid overtreatment in some of these cases.
