BACKGROUND/OBJECTIVES: To describe the method of diagnosis, clinical management and adherence to clinical practice guidelines for melanoma patients at high risk of a subsequent primary melanoma, and compare this with melanoma patients at lower risk.

METHODS

The Melanoma Patterns of Care study was a population-based, observational study based on doctors' reported clinical management of melanoma patients in New South Wales, Australia, diagnosed with in situ or invasive melanoma over a 12-month period from October 2006. Of 2605 patients with localised melanoma, 1019 (39%) were defined as at higher risk due to the presence of one or more of the following factors: a family history of melanoma (11%), multiple primary melanomas (17%), or many naevi (24%).

RESULTS

Compared to patients at lower risk, high risk patients were more likely to receive their initial care from a primary care physician (56% vs 50%, P = 0.002), have their melanoma detected during a routine skin check (40% vs 33%, P < 0.001), have their lesion assessed with dermoscopy (63% vs 56%, P = 0.002), and be encouraged to have skin surveillance (84% vs 77%, P < 0.001) and skin self-examination (87% vs 83%, P = 0.03). Higher socioeconomic status and urban residence were associated with patients at higher risk receiving initial treatment from a specialist doctor.

CONCLUSIONS

Clinical management of higher risk patients was more likely to conform to clinical practice guidelines for diagnosis and skin surveillance than to melanoma patients at lower risk.
