SummaryBackgroundPrevious studies from our group had identified c-myc oncoprotein expression as an important prognostic parameter in a series of retrospective studies of primary and metastatic melanoma and other variants of this disease. This study set out to prospectively evaluate the prognostic significance of c-myc positivity in a consecutive series of primary melanomas presenting at Mount Vernon Hospital Regional Plastic Surgery and Burns Centre.MethodsA consecutive series of 117 primary melanomas underwent flow cytometric analysis for c-myc expression at diagnosis. Routine clinical and histological parameters were collected from each patient's clinical records and survival assessed. The mean follow up was 45 months.ResultsKaplan–Meier survival analysis demonstrated that Breslow depth, histogenic subtype, ulceration, age and sex had prognostic significance. Survival analysis revealed high c-myc positivity to be significantly associated with poorer outcome (P < 0.043). Each of the main prognostic parameters were assessed for their independent significance using Cox Proportional Hazards; only c-myc retained independent significance (P < 0.039).ConclusionsThe strength of this study is that it was performed in a consecutive series of patients followed up in a longitudinal prospective study. c-myc was not the strongest predictor of survival in univariate analysis, but was the only parameter that retained significance in multivariate analysis.
