Abstract

The aim of this study was to evaluate whether cisplatin sensitivity relates to patient's prognosis in oesophageal squamous cell carcinoma and to find a useful chemosensitivity molecular marker. 59 oesophageal squamous cell carcinoma (SCC) patients received cisplatin 30 mg/m2/week treatment of two to five cycles, followed by oesophagectomy. We analysed retrospectively whether the histological effect was related to patient's prognosis. Furthermore, to evaluate the relationship between the effect of preoperative cisplatin treatment and p53 and cyclin D1 expression, we investigated p53 and cyclin D1 expression in pretreatment biopsy samples using an immunohistochemical analysis and compared the results with the histological effect to cisplatin in the resected oesophagus. The cases that showed immunohistochemical p53 staining in the pretreatment biopsy samples were resistant to cisplatin (P=0.032). However, there was no relationship between cyclin D1 expression and histological effect (P=0.230). Nevertheless, combined analysis of p53 and cyclin D1 can predict histological effect (P=0.032). The prognosis of cisplatin-sensitive cases was significantly better than that of cisplatin-resistant cases (P=0.041). Cox's multivariate analysis revealed that the histological effect was an independent prognostic factor. In contrast, p53 protein accumulation and cyclin D1 were not. Histological response after neoadjuvant cisplatin treatment is a prognostic factor for oesophageal SCC and cisplatin chemotherapy may be selected according to the findings of p53 and cyclin D1 expression.
