Carbon ion radiotherapy (CIRT) may yield satisfactory clinical outcomes for patients who are resistant to radiotherapy. However, the therapeutic impact of carbon ions is still limited in certain recurring or refractory tumors. Therefore, we aimed to evaluate the synergistic anti-tumor effects of immune checkpoint inhibitors (ICIs) in combination with CIRT.

Background: Rhabdomyosarcoma (RMS) is rare in adults, with a significantly worse prognosis than its pediatric counterpart. Radiotherapy (RT) plays a significant role in treating head and neck RMS (HNRMS), but the outcomes of conventional RT are limited by the complex anatomy and unfavorable pathology subtypes of the adult H&N RMS. Here, we aim to report the effectiveness and safety of carbon-ion beam RT (CIRT), either alone or in combination with proton radiotherapy (PRT) in the management of adult HNRMS.

Background: Nasopharyngeal adenoid cystic carcinoma (NACC) is a distinct subgroup of adenoid cystic carcinoma (ACC) with limited surgical access but predilection of regional and distant metastasis. Although radiotherapy is an integral treatment for patients with NACC, photon-based radiotherapy yielded suboptimal local control. Because of its advantages in biology and physics properties, carbon-ion radiotherapy (CIRT) was attempted for the treatment of head and neck ACC; however, the use of CIRT specifically for NACC has not been investigated.

Background: Although carbon-ion radiotherapy (CIRT) may improve outcome for patients with locoregionally recurrent nasopharyngeal carcinoma (LR-NPC), local progression still remains one of the major failure patterns. This suggests an unmet need of markers for predicting disease control after re-irradiation and potentially guiding tailored treatment. The purpose of this study was to explore the predictive value of pre-treatment 3'-deoxy-3'-[F]fluorothymidine (FLT)-positron emission tomography (PET) for patients with locally advanced LR-NPC.

Photon-based radiotherapy upregulates Notch signaling in cancer, leading to the acquisition of the stem cell phenotype and induction of invasion/migration, which contributes to the development of resistance to therapy. However, the effect of carbon ion radiotherapy (CIRT) on Notch signaling in glioma and its impact on stemness and migration is not explored yet. Human glioma cell lines (LN229 and U251), stable Notch1 intracellular domain (N1ICD) overexpressing phenotype of LN229 cells, and Notch inhibitor resistant LN229 cells (LN229R) were irradiated with either photon (X-rays) or (carbon ion irradiation) CII, and expressions of Notch signaling components were accessed by RT-PCR, Western blotting, and enzymatic assays and flow cytometry.
