Trends in incidence and survival analysis in non-melanoma skin cancer from 1994 to 2012 in Girona, Spain: A population-based study

Abstract

Introduction: We present an epidemiological study focused on Non-melanoma skin cancers (NMSC), including squamous cell carcinoma (SCC), basal cell carcinoma (BCC), Merkel cell carcinoma (MCC), dermatofibrosarcoma protuberans (DFS) and adnexal and skin appendages neoplasm (ASAN), a neoplasm understudied in cancer registries.

Material and methods: We analyze trends of incidence and survival of NMSC registered with the Cancer Registry of Girona, Spain.

Results: We found 14389 cases of NMSC, accounting 3,474 SCC, 10729 BCC, 33 MCC, 61 DFSP and 71 ASAN. Incidence increased significantly in SCC and BCC with annual percentage of change of 1.6 and 1.5, respectively, but not in MCC, DFS or ASAN. Five-year relative survival for both sexes was 90.1% in SCC, 99.8% in BCC, 44.2% in MCC, 93.7% in DFS and 84% in ASAN.

Conclusions: Our study confirms the increasing incidence and good survival of SCC and BCC and enhances knowledge on the epidemiology of the less incidental NMSC.
