Abstract: Hyperacidified tumors having high .beta.-glucuronidase activity can be treated with glucuronides with aglycones toxic to the tumor cells with great safety toward the rest of the body by first administering an alkalinizing agent in an amount sufficient to maintain the pH level of non-tumor tissues at approximately 7.4 during the glucuronide treatment.
