In particular, when the stilbene derivative exhibiting an antitumor activity is used in combination with the above platinum coordination compound, the antitumor activity inherent to the stilbene derivative is further enhanced to give an antitumor agent having an improved efficaciousness which is particularly adequate for treating malignant tumors. Further, there are also provided uses of these active ingredients as the pharmaceutical preparation and for the treatment thereof and the like, as well as methods for using them therefor.
