    • CA-IX levels are predictive of the probability that a cancer patient will respond favorably to cancer therapy involving administration of a hypoxia-activated prodrug. In a first aspect, the present invention provides a method for treating cancer comprising the steps of measuring CA-IX levels in a sample isolated from the patient, and administering a hypoxia-activated prodrug only if the CA-IX level measured is equal to or greater than about 30 pg/mL (e.g. 28.8 pg/mL) CA-IX protein in a serum sample, as may be measured, for example or without limitation, using an ELISA. In one embodiment, a HAP is administered if the measured CA-IX level is equal to or greater than about 75 pg/mL (e.g. 77.1 pg/mL) protein in a serum sample. Thus, in one embodiment, the CA-IX level is measured based on the amount of CA-IX protein in a serum sample.
    • CA-IX水平可预测癌症患者对涉及施用缺氧激活的前药的癌症治疗有积极响应的可能性。 在第一方面,本发明提供了一种治疗癌症的方法,其包括以下步骤:测量从患者分离的样品中的CA-IX水平,并且仅当所测量的CA-IX水平等于或低于 例如但不限于,使用ELISA可以测量血清样品中大于约30pg / mL(例如28.8pg / mL)的CA-IX蛋白。 在一个实施方案中,如果测量的CA-IX水平在血清样品中等于或大于约75pg / mL(例如77.1pg / mL),则施用HAP。 因此,在一个实施方案中,基于血清样品中CA-IX蛋白的量来测量CA-IX水平。
