Described herein are methods of treating cancer by administering a therapeutically effective amount of at least one texaphyrin metal complex or a pharmaceutically acceptable derivative, and performing stereotactic radiosurgery to the patient. In some embodiments, at least one texaphyrin metal complex or a pharmaceutically acceptable derivative is administered while the patient is undergoing a radiation therapy. Also described herein are methods for detecting various cancerous tumors, lesions, or metastases in a patient by administering an effective amount of at least one texaphyrin metal complex or a pharmaceutically acceptable derivative before a patient undergoes stereotactic radiosurgery. Also described herein are methods for visualizing tumors not otherwise visualized; methods for detecting the margins of a tumor; and methods for improving the targeting of the SRS radiation.

La présente invention concerne des procédés de traitement du cancer par l'administration d'une quantité thérapeutiquement efficace d'au moins un complexe métallique de la texaphyrine ou un dérivé pharmaceutiquement acceptable et en pratiquant une radiochirurgie stéréotactique sur le patient. Dans certains modes de réalisation, au moins un complexe métallique de la texaphyrine ou un dérivé pharmaceutiquement acceptable est administré pendant que le patient subit une radiothérapie. L'invention concerne également des procédés qui permettent de détecter diverses tumeurs cancéreuses, des lésions ou des métastases chez un patient en administrant une quantité efficace d'au moins un complexe métallique de la texaphyrine ou un dérivé pharmaceutiquement acceptable avant que le patient subisse une radiochirurgie stéréotactique. L'invention concerne en outre des procédés qui permettent de visualiser des tumeurs qui ne sont pas visualisées autrement, des procédés qui permettent de détecter les marges d'une tumeur et des procédés qui permettent d'améliorer le ciblage du rayonnement de la radiochirurgie stéréotactique.
