title: Combination of angiogenesis inhibitor TNP-470 with cytotoxic drugs in experimental therapy of nasopharyngeal carcinoma.
abstract: This study was conducted to evaluate the effectiveness of angiogenesis inhibitor 6-O-(N-chloroacetyl-carbamoyl)-fumagillol (TNP-470. AGM-1470) in the treatment of nasopharyngeal carcinoma (NPC) alone and in combination with cytotoxic agents. Forty-two male BALB/c nude mice bearing human NPC cell line CNE-2 were randomized into 6 groups: those treated with saline solution, TNP-470, cisplatin (DDP), fluorouracil (5-FU), TNP-470 + DDP, and TNP-470 + 5-FU, respectively. In every treatment group, tumor growth was suppressed significantly. The combination of 5-FU with TNP-470 showed significant enhancement in antitumor efficacy. TNP-470 also enhanced the inhibitory effect of DDP, although not to statistical significance. All animals gained in body weight, although treatment with 5-FU caused slight, reversible diarrhea of 2 to 3 days' duration. The results showed that TNP-470 suppressed the growth of the human NPC cell line and enhanced the antitumor effect of 5-FU without increasing its toxicity. The combination of angiogenesis inhibitors with conventional cytotoxic agents is promising in the treatment of NPC.
