Epidemiology of melanoma in rural southern Queensland

Epidemiology of melanoma in rural southern Queensland

Objective: The objective of this study is to define the epidemiology of melanoma in rural communities in southern Queensland.

Design: The design used was a 6‐year clinical record audit of melanoma cases identified by billing records and electronic clinical records, confirmed and typed with histology.

Setting and Participants: This study was based on seven agricultural communities on the Darling Downs with patients presenting to local primary care clinics.

Main outcome measures: Outcomes measured were confirmed type, depth and anatomic distribution of melanoma identified at these practices during the study period.

Results: The results from 317 cases of melanoma found anatomic distribution was significantly different (χ2 = 9.6, P < 0.05) to that reported previously from the Queensland Cancer Registry. A high proportion (87%) of melanoma diagnosed by these general practitioners were 1 mm or less when treated.

Conclusions: Conclusions drawn from these findings are that melanoma risk is not so much lesser in rural, inland communities compared with coastal and metropolitan
regions, but different. Differences may relate to comprehensive data capture available in rural community studies and to different sun exposure and protection behaviours. The higher proportion of melanoma identified at early stages suggests rural primary care is an effective method of secondary prevention.
