Skin cancer excision performance in Scottish primary and secondary care: a retrospective analysis.

BACKGROUND

In contrast with most published evidence, studies from north-east Scotland suggest that GPs may be as good at treating skin cancers in primary care as secondary care specialists.

AIM: To compare the quality of skin cancer excisions of GPs and secondary care skin specialists in east and south-east Scotland.

DESIGN AND

SETTING

A retrospective analysis of reports from GPs in Lothian, Fife, and Tayside regions.

METHOD: Skin cancer histopathology reports from GPs in Lothian, Fife, and Tayside regions in 2010 were compared with reports from skin specialists in November 2010. The histopathology reports were rated for completeness and adequacy of excision.

RESULTS

A total of 944 histopathology reports were analysed. In 1 year, GPs biopsied or excised 380 skin cancers. In 1 month, dermatologists biopsied or excised 385 skin cancers, and plastic surgeons 179 skin cancers. 'High risk' basal cell carcinomas (BCC) comprised 63.0% of BCC excised by GPs. For all skin cancer types, GPs excised smaller lesions, and had a lower rate of complete excisions compared with skin specialists. A statistical difference was demonstrated for BCC excisions only.

CONCLUSION

GPs in east and south-east Scotland excise a number of skin cancers including malignant melanoma (MM), squamous cell carcinoma (SCC) and high-risk BCC. Despite removing smaller lesions, less commonly on difficult surgical sites of the head and neck, GP excision rates are lower for all skin cancers, and statistically inferior for BCC, compared with secondary care, supporting the development of guidelines in Scotland similar to those in other UK regions. Poorer GP excision rates may have serious consequences for patients with high-risk lesions.
