MATERIALS AND METHODS: To investigate the prognosis of primary melanoma, we studied a Finnish population of 298 primary melanoma patients, the majority with stage I or II tumours. The median clinical follow-up (4.8 years) was acquired from the patients' records, and the overall survival thereafter was collected from patient registries. The median follow-up for overall survival was 9.5 years.
RESULTS: The overall survival rate was 66.8%. 24.5% developed metastasis, 17.8% died of melanoma, and 15.4% died of some other cause. Surgical margins had no effect on survival. In univariate analysis the most significant prognostic factors for disease-free and overall survival were stage of tumour (p < 0.0001), thickness of tumour (p < 0.0001), depth of tumour invasion (p < 0.0001) and tumour ulceration (p = 0.0005, p < 0.0002). Ulceration was an unfavorable prognostic marker. Younger patients had better survival outcomes than older ones (p = 0.04). Accordingly, in the multivariate Cox model the independent prognostic factors for both disease-free and overall survival were stage of tumour and thickness of tumour. Tumour location on trunk was an independent adverse prognosticator for overall survival.
CONCLUSION: We conclude that the prognosis of primary melanoma has improved in Finland in the last decades being in line with a global tendency.
