Anti-CAR Antibodies May Undermine Cell Therapy in Brain Tumors

Chimeric antigen receptor T-cell therapies for brain tumors have shown limited durability, in part because of an antibody attack on the engineered receptor itself, new research shows.

Neoadjuvant short-course radiotherapy followed by camrelizumab and chemotherapy versus standard of care for locally advanced rectal cancer (UNION): a prespecified interim analysis of a multicentre, open-label, randomised, phase 3 trial

In this interim analysis, short-course radiotherapy followed by camrelizumab and CAPOX significantly improved 3-year event-free survival in patients with locally advanced rectal cancer, with a safety profile similar to long-course chemoradiotherapy followed by CAPOX. Comparison of this promising new treatment strategy with contemporary total neoadjuvant therapy strategies is warranted.

Curative-intent management of de novo metastatic nasopharyngeal carcinoma: an evidence-based consensus guideline from the International Collaborating Oncology Organisations

This guideline provides a practical framework for standardisation of clinical management of de novo metastatic nasopharyngeal carcinoma and identification of key evidence gaps for future research. We recommend that curative-intent treatment should be offered to medically fit patients with no more than three metastatic lesions in two or fewer organs at baseline or following response to systemic therapy; multimodality treatment (comprising immunochemotherapy, locoregional radiotherapy, metastasis-directed therapy, and maintenance therapy) is recommended.
