Progress of Research on Combination of Intratumoral Immune Injection and Radiotherapy for Tumor / 肿瘤防治研究

With the rapid development of tumor immunotherapy in recent years, therapeutic cancer vaccines are attracting increased attention. Compared with personalized neoantigen vaccines, in situ vaccines could form an antigen reservoir in the tumor itself. Subsequently, antitumor immunity is initiated and the response to immune-checkpoint inhibitors of some patients improve without necessitating these patients to undergo the complicated procedures of detecting personalized antigen and customizing and synthesizing antigen peptide. At this stage, the potential of realizing the clinical translation of in situ vaccination is tremendous. In this review, we primarily introduce the mechanisms of radiotherapy and intratumoral immune injection as in situ vaccination and discuss the current status of preclinical study and clinical application of their combination to attract more attention from researchers and clinicians toward in situ vaccination.

Research progress on application of the combination of radiotherapy and immune-checkpoint blockade in treatment of stage Ⅲ unresectable non-small cell lung cancer / 中华放射肿瘤学杂志

Chemoradiation has been the standard treatment of stage Ⅲ unresectable non-small cell lung cancer (NSCLC) for a long period of time. However, the clinical efficacy of chemoradiation has not been significantly improved in recent two decades. In the past 2-3 years, the role of immune-checkpoint inhibitors in metastatic NSCLC has been persistently strengthened. Moreover, the synergistic effect between radiotherapy and immune-checkpoint blockade has been conformed in pre-clinical and clinical studies. Recent clinical trials have demonstrated that the combination of radiotherapy and immune-checkpoint blockade has been proven to be more effective in the treatment of stage Ⅲ unresectable NSCLC. In this article, the latest clinical studies since 2017 regarding the application value of this combined treatment of stage Ⅲ unresectable NSCLC were summarized.

Applications and mechanism of some clinical common medications used as anti-cancer therapy sensitizer / 国际肿瘤学杂志

A number of medications have been proved to be able to either improve the antitumor effect of chemotherapeutics and molecular targeted drugs or reverse the resistance of tumors to chemotherapeutics and molecular targeted drugs,which are not traditionally used as anticancer drugs.Especially for late-stage tumors after multiple treatments,these agents are good alternatives when used independently or in combination with chemotherapeutics and molecular targeted drugs.These drugs include proton modulators,hypoglycemic agents and cardiovascular agents,etc.
