NRG-BN010 immuno-RT combination failed to improve response in recurrent glioblastoma
Tocilizumab, atezolizumab and 24 Gy/3-fraction FSRT produced only a 3.4% objective response rate in recurrent glioblastoma.
Tocilizumab, atezolizumab and 24 Gy/3-fraction FSRT produced only a 3.4% objective response rate in recurrent glioblastoma.
Across 7,694 patients, most SRT–systemic therapy combinations appeared tolerable, but BRAF/MEK inhibitors, T-DM1 and liver SRT showed caution signals.
Concurrent durvalumab with either 60 Gy/15 or 60 Gy/30 was feasible in a 24-patient phase I study without concurrent chemotherapy.
Concurrent and consolidation ICI produced similar pathological response rates once analyses were restricted to neoadjuvant chemoradiotherapy studies.
Metformin plus radiotherapy prolonged survival in two syngeneic glioblastoma models while shifting macrophage and T-cell populations toward antitumor phenotypes.
Durvalumab, tremelimumab and SBRT produced 72.7% six-month progression-free survival in 33 patients with oligometastatic HNSCC.
Recent trials report 40–61% pathologic complete response with short-course radiotherapy plus immunotherapy, but mature comparative outcomes remain unavailable.
International experts identified eight research priorities covering biomarker-guided chemoradiation, immunotherapy sequencing, and consolidation radiotherapy in metastatic head and neck cancer.
Neither fractionation schedule rejected the prespecified progression-free survival benchmark; durable benefit was confined to patients with oligometastatic disease.
Twelve trials used 14 immunotherapy regimens with major differences in eligibility, radiotherapy, chemotherapy, endpoints, and translational analysis.
Radiation reached 60 Gy in 15 fractions with adjuvant atezolizumab, while concurrent dosing was followed by HSV-1 reactivation in three of five patients.
Concurrent and consolidative durvalumab with definitive radiotherapy produced 39% two-year progression-free survival in patients ineligible for concurrent chemoradiotherapy.
PVC was detected in 37 of 72 HCC tumors and was associated with poorer response and progression-free survival after SBRT, immunotherapy, and bevacizumab.
Consolidation durvalumab after concurrent chemoradiotherapy halved the adjusted risk of progression or death at two years in real-world stage III NSCLC.
This systematic review found that optimal radiotherapy-immunotherapy sequencing depends on the immune mechanism being targeted.
