Abstract:
:Tumor cell migration involved in metastases is a tightly regulated, nonrandom process. Chemokines have been identified as critical molecules guiding cell migration. We performed a prospective study to analyze a possible association between the expression of chemokine receptors CXCR3 and CXCR4 by primary melanoma and clinical outcome. Forty primary melanomas were available for analysis; 57% of the tumors expressed CXCR3 and 35% expressed CXCR4 by melanoma cells. At initial diagnosis, 5 patients had subclinical lymph node involvement and after a median follow-up time of 32 months, 2 additional patients developed regional lymph node metastases and 5 patients developed distant metastases. The expression of CXCR4, but not CXCR3, by melanoma cells in primary lesions was significantly associated with the presence of ulceration, increased tumor thickness, a greater risk of developing regional and distant metastases and a higher mortality rate. Our study underscores the value of CXCR4 expression as a useful marker for predicting outcome in patients with localized melanoma. In addition, our findings support that, among chemokine receptors, CXCR4 might be an appropriate therapeutic target for adjuvant therapy in patients at risk for metastatic disease.
