Overview
The purpose of this study is to evaluate the retention in tumour and distribution behavior of [Lu-177]-Catalase after intratumoral injection,and preliminary evaluation the efficacy and safety of [Lu-177]-Catalase.
Description
After being informed about the study and potential risks, all patients giving written informed consent will undergo a 2-week screening period to determine eligibility for study entry. At day1, patients who meet the eligibility requirements will be intratumoral injection the [Lu-177]-Catalase.The efficacy evaluation will be conducted at one month p.i., whether to continue intratumoral injection the [Lu-177]-Catalase, depending on the patient's efficacy and safety results.
