Positive EGFR expression in distant metastatic melanoma was significantly correlated with the absence of ulceration, and associated with poor survival outcomes. This study highlights the predictive value of EGFR immunostaining for survival outcome in male, non-ulcerated, or Breslow thickness 54.0 mm distant metastatic melanoma cases.
Background: Epidermal growth factor receptor (EGFR) is overexpressed in many cancers. However, EGFR expression in melanoma and its role are conflicting. Objective: This study aimed to evaluate EGFR expression in distant metastatic melanoma and analyze its relationship with histologic and clinical characteristics and survival. Methods: Diagnostic tissues from 55 cases of distant metastatic melanoma was evaluated by immunohistochemistry for EGFR expression. Clinicopathologic features and survival outcomes were analyzed according to EGFR expression. Results: The positive EGFR expression in distant metastatic melanoma was significantly correlated with the absence of ulceration. The EGFR expression in distant metastatic melanoma was significantly associated with poor survival, under the conditions of male sex and primary cutaneous melanoma without ulceration or Breslow thickness 54.0 mm. This study bears limitations of a retrospective study in a single institution. Conclusion: EGFR immunostaining had predictive values for survival outcome. The EGFR expression in distant metastatic melanoma in male, no ulcer, or Breslow thickness 54.0 mm appeared to be involved in disease progression. (Ann Dermatol 33(5) 432 similar to 439, 2021)
