An experimental model of tumor dormancy therapy for advanced head and neck carcinoma was developed. After transplantation of KB cells into nude mice, the mice were given tiracoxib, a selective cyclooxygenase (COX)-2 inhibitor, probucol, an antioxidant, and S-1, an oral pro-drug of 5-fluorouracil (5-FU), or combinations of two of them. The combined administration of tiracoxib with probucol significantly inhibited the tumor growth. The angiogenesis in this group was markedly reduced. Tiracoxib and probucol did not affect the intratumoral concentration of 5-FU when coadministered with S-1. The combined use of tiracoxib and probucol is thus a candidate for use in maintenance therapy after the primary therapy for patients with advanced head and neck carcinoma.
建立了晚期头颈癌肿瘤休眠治疗的实验模型。将KB细胞移植到裸鼠体内后,给小鼠服用塞来昔布(一种选择性环氧化酶(COX)-2抑制剂)、普罗布考(一种抗氧化剂)和S-1(5-氟尿嘧啶(5-FU)的口服前体药物),或其中两种药物的组合。塞来昔布与普罗布考联合给药显著抑制了肿瘤生长。该组的血管生成明显减少。塞来昔布和普罗布考与S-1合用时不影响肿瘤内5-FU的浓度。因此,塞来昔布和普罗布考联合使用是晚期头颈癌患者初始治疗后维持治疗的候选方案。
