Background
Follow-up practices after diagnosis and treatment of primary cutaneous melanoma vary considerably. We aimed to determine factors associated with recommendations for follow-up setting, frequency, skin surveillance, and concordance with clinical guidelines.
Methods
The population-based Melanoma Patterns of Care study documented clinicians’ recommendations for follow-up for 2148 patients diagnosed with primary cutaneous melanoma over a 12-month period (2006/2007) in New South Wales, Australia. Multivariate log binomial regression models adjusted for patient and lesion characteristics were used to examine factors associated with follow-up practices.
Results
Of 2158 melanomas, Breslow thickness was < 1 mm for 57% and ≥ 1 mm for 30%, while in situ melanomas accounted for 13%. Follow-up was recommended for 2063 patients (96%). On multivariate analysis, factors associated with a recommendation for follow-up at a specialist center were Breslow thickness ≥ 1 mm [prevalence ratio (PR) 1.05, 95% confidence interval (CI) 1.01–1.09] and initial treatment at a specialist center (PR 1.12, 95% CI 1.08–1.16). Longer follow-up intervals of > 3 months were more likely to be recommended for females, less likely for people living in rural compared with urban areas, and less likely for thicker (≥ 1 mm) melanomas compared with in situ melanomas. Skin self-examination was encouraged in 84% of consultations and was less likely to be recommended for patients ≥ 70 years (PR 0.88, 95% CI 0.84–0.93) and for those with thicker (≥ 1 mm) melanomas (PR 0.92, 95% CI 0.86–0.99). Only 1% of patients were referred for psychological care.
Conclusions
Follow-up recommendations were generally consistent with Australian national guidelines for management of melanoma, however some variations could be targeted to improve patient outcomes.
