Background/Objective Information on the prognosis for patients with regional cutaneous melanoma metastases has been sparse and difficult to establish. In 2009 the A merican Joint Committee on Cancer ( AJCC ) melanoma staging has for the first time provided survival rates for patients who manifest intralymphatic metastases. We sought to validate the new staging system in this contemporary, prospectively collected cohort of patients following the development of cutaneous metastases as the first evidence of metastatic disease and explored the factors that influenced their prognosis. Methods The V ictorian Melanoma Service database was searched to identify all patients with cutaneous melanoma metastases. Patients who were found to have lymph node or visceral metastases at the time they were diagnosed with cutaneous metastatic disease were excluded. Survival curves were generated and univariate and multivariate assessments of prognostic factors associated with survival were performed. Results In total, 72 patients presented with cutaneous metastases as the first evidence of metastatic disease. The median melanoma‐specific survival of patients with only regional cutaneous metastases ( n = 56) was 5.07 years and their 5‐year survival rate was 52%. Distant cutaneous metastases and thickness of the primary melanoma were found to be significant negative predictors of survival. Conclusion We were able to validate the new AJCC melanoma staging system survival for patients with cutaneous metastatic disease. Patients presenting with regional cutaneous metastases have a much better prognosis than those with distant cutaneous metastases.
