Neoadjuvant chemotherapy shifted HR+/HER2− breast tumors toward higher genomic radioresistance
RSI increased after neoadjuvant chemotherapy in 23 of 30 matched HR+/HER2− tumors, but implications for adjuvant radiation dose remain unproven.

Cannabinoids reduced glioblastoma apoptosis after chemotherapy and radiation in vitro
Several cannabinoids reduced therapy-induced glioblastoma apoptosis and enhanced clonogenic survival in vitro, raising concern about concurrent use during treatment.
Low CAVIN3 expression was associated with better radiotherapy response in cervical cancer
Low CAVIN3 expression was associated with higher treatment response and substantially longer progression-free survival after radiotherapy for cervical cancer.
CHAF1A promotes DNA repair and tumor radioresistance through RAD51 and KU70
CHAF1A supported homologous recombination and non-homologous end joining, while its depletion increased radiosensitivity in xenograft models.
TFDP2-PDK3 metabolic signaling drove nasopharyngeal carcinoma radioresistance
TFDP2 activated PDK3, shifted nasopharyngeal carcinoma cells toward glycolysis, and reduced radiation response in cellular and xenograft models.
Review links chemoresistance and radioresistance through shared adaptive programmes
Chemotherapy and radiotherapy resistance may converge on shared DNA-repair, redox, metabolic, stemness and microenvironmental adaptations.
DCAF4 promoted hepatocellular carcinoma resistance to iodine-125 brachytherapy
DCAF4 activated NRF2-dependent antioxidant defence and protected hepatocellular carcinoma against iodine-125 brachytherapy in preclinical models.
Intratumoral polyvinyl chloride was associated with radioresistance in hepatocellular carcinoma
PVC was detected in 37 of 72 HCC tumors and was associated with poorer response and progression-free survival after SBRT, immunotherapy, and bevacizumab.
Insufficient ferroptosis promoted regulatory T-cell accumulation and radiotherapy resistance
Radioresistant tumors showed impaired ferroptosis and regulatory T-cell accumulation, while sorafenib enhanced the response to irradiation in mice.
