Overexpression of the oncogene HDM2 is observed in a substantial proportion of melanomas, including noninvasive and thin lesions, suggesting that HDM2 overexpression may be an early event in melanocyte transformation. To determine the role of HDM2 in the clinical progression of melanoma, we examined whether its expression was associated with patient survival. From November 1972 through November 1982, 134 patients with melanoma who participated in the New York University Melanoma Cooperative Group were studied, if representative tissues and follow-up were available. HDM2 protein expression was assessed immunohistochemically. Unexpectedly, we observed that HDM2 overexpression was statistically significantly associated with improved disease-free survival (relative risk [RR] = 0.47, 95% confidence interval [CI] = 0.24 to 0.89; two-sided chi(2) P =.021) and overall survival (RR = 0.55, 95% CI = 0.33 to 0.94; two-sided chi(2) P =.027) in multivariable analysis. HDM2 overexpression appears to be an independent predictor of survival for patients with primary melanoma; however, larger prospective studies are required for validation. [ABSTRACT FROM AUTHOR] |
