The clinical significance of c-myc oncogene expression in melanomas of the scalp.
Melanomas of the scalp are rare and have a poorer prognosis than melanomas arising at other cutaneous sites. In order to study the biology of this disease, the activity of the c-myc oncogene was studied in tumours from 25 patients with scalp melanoma using the technique of flow cytometry. Survival analysis revealed that stratification of patients according to oncogene activity provided a prognostic marker with shorter overall survival (log rank test, chi 2 = 3.9, P = 0.05) in tumours with high nuclear c-myc oncoprotein positivity. These results support our previous studies of the prognostic value of c-myc expression in melanoma and suggest that estimation of c-myc oncoprotein may be of clinical significance in identifying high risk patients.
