Recent studies have highlighted the synergistic potential of combining radiotherapy with immunotherapy to enhance treatment outcomes in various cancers. The ENGOT-cx11/GOG-3047/KEYNOTE-A18 trial demonstrated that adding pembrolizumab to chemoradiotherapy significantly improved progression-free survival in patients with high-risk locally advanced cervical cancer, with 78% of patients experiencing grade 3 or higher adverse events (ref: Lorusso doi.org/10.1016/S0140-6736(24)01808-7/). In the context of non-small cell lung cancer (NSCLC), the LAURA study revealed that osimertinib post-chemoradiotherapy led to a 9% cumulative incidence of CNS progression, significantly lower than the 36% observed with placebo, indicating a potential role for targeted therapies in managing CNS metastases (ref: Lu doi.org/10.1016/j.annonc.2024.08.2243/). Furthermore, the use of Epstein-Barr virus-specific cytotoxic T lymphocytes in combination with gemcitabine and carboplatin showed promising results in recurrent nasopharyngeal carcinoma, suggesting that immunotherapeutic strategies can be effectively integrated with conventional chemotherapies (ref: Toh doi.org/10.1016/j.annonc.2024.08.2344/). Additionally, novel approaches such as cuproptosis nanocapsules have been proposed to sensitize tumors to radiotherapy, while YTHDF1 loss in dendritic cells was found to enhance radiation-induced antitumor immunity, indicating that the tumor microenvironment plays a crucial role in modulating treatment efficacy (ref: Liao doi.org/10.1038/s41565-024-01784-1/; Wen doi.org/10.1172/JCI181612/). These findings collectively underscore the importance of understanding the interactions between radiotherapy and immunotherapy to optimize cancer treatment strategies.
