Using a currently used linear accelerator we intended to inactivate peroxidase/catalase in a topical tumor tissiue by the application of hydrogen peroxide, thus re-oxygenizing the tumor tissue by the oxygen produced by the hydrogen peroxide degradation. In this way, we can convert radioresistant tumors into radiosensitive ones.On the basis of this strategy, we have developed a new enzyme-targeted radiosensitization treatment named KORTUC I (Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type I), which remarkably enhances the radiotherapeutic effect on various types of superficial & locally advanced malignant neoplasms. In the method, the surface of the tumor is covered by hydrogen peroxide solution (Oxydol)-soaked gauze during each administration of radiation therapy.Based on our clinical experiences using KORTUC I, we also developed a new radiosensitizer containing hydrogen peroxide and sodium hyaluronate for topical tumor injection for various types of tumors which are not superficially exposed (KORTUC II). KORTUC II was accepted by our local ethical committee concerning of the use for skin cancer, bone/soft tissue malignant neoplasms, breast cancer, and metastatic lymph nodes. Maximally 3 ml of the agent was injected into topical tumor tissue, one to two times per week, under an ultrasonographic guide just prior to each administration of radiation therapy.Fifteen patients including 10 breast cancer patients were enrolled in the KORTUC II trial upon fully informed consent. Twelve of the patients showed clinically complete response by the new enzyme-targeting radiosensitization treatment (KORTUC II) without any severe complications. The method can be indicated for various types of locally advanced neoplasms.

使用目前使用的线性加速器，我们打算通过过氧化氢的应用使局部肿瘤组织中的过氧化物酶/过氧化氢酶失活，从而通过过氧化氢降解产生的氧气重新氧化肿瘤组织。通过这种方法，我们可以将耐辐射肿瘤转化为辐射敏感肿瘤。在此基础上，我们开发了一种新的酶靶向放射增敏治疗方法KORTUC I (Kochi Oxydol-Radiation Therapy for unresection Carcinomas, Type I)，显著提高了对各种类型的浅表和局部晚期恶性肿瘤的放射治疗效果。在该方法中，在每次放射治疗期间，肿瘤表面被过氧化氢溶液（Oxydol）浸泡的纱布覆盖。根据我们使用KORTUC I的临床经验，我们还开发了一种新的含有过氧化氢和透明质酸钠的放射增敏剂，用于各种类型的非表面暴露肿瘤的局部肿瘤注射（KORTUC II）。KORTUC II已被当地伦理委员会接受用于皮肤癌、骨/软组织恶性肿瘤、乳腺癌和转移性淋巴结。在每次放射治疗之前，在超声引导下，将最多3ml的药物注射到局部肿瘤组织中，每周一到两次。包括10名乳腺癌患者在内的15名患者在完全知情同意的情况下参加了KORTUC II试验。12例患者通过新的酶靶向放射增敏治疗（KORTUC II）显示临床完全缓解，无严重并发症。该方法适用于各种类型的局部晚期肿瘤。
