Figure 1From: High ERCC1 expression predicts cisplatin-based chemotherapy resistance and poor outcome in unresectable squamous cell carcinoma of head and neck in a betel-chewing areaAnalysis of ERCC1 expression in head and neck squamous cell carcinoma. ERCC1 expression was determined using immunohistochemistry. A) Low ERCC1 expression (200× magnification). B) High ERCC1 expression (200× magnification).Back to article page
