Abstract
An antitumor pharmaceutical composition and an application thereof. Active ingredients of the antitumor pharmaceutical composition contain a polyethylene glycol-modified camptothecin derivative (in particular, polyethylene glycol-modified irinotecan) and temozolomide. It is proved by means of animal experiments that the administration of polyethylene glycol-modified camptothecin derivative (in particular, polyethylene glycol-modified irinotecan) and temozolomide in combination has an extremely strong treatment effect on tumors (such as neuroblastoma), and the tumor inhibition rate can reach 98% and is significantly superior to that of a monotherapy group; thus, the provided antitumor pharmaceutical composition has better application prospects for treatment of tumors.
