The integration of genomic profiling into clinical practice is further supported by the findings of a cluster-randomized trial on Epstein-Barr virus serology screening, which indicated a significant reduction in nasopharyngeal carcinoma mortality (ref: Chen doi.org/10.1200/JCO.23.01296/). These studies collectively highlight the potential of genomic biomarkers to inform treatment strategies and improve patient outcomes in cancer care.

Understanding tumor resistance mechanisms is crucial for developing effective therapeutic strategies. Recent research has identified the role of circular RNA ADARB1 in enhancing radiosensitivity in nasopharyngeal carcinoma through promoting ferroptosis, suggesting a novel approach to overcome radiotherapy resistance (ref: Wang doi.org/10.1021/acsnano.4c07676/). Additionally, the loss of miR-200c-3p was found to promote radioresistance in prostate cancer via the DNA repair pathway, indicating that targeting specific microRNAs may offer new avenues for sensitizing resistant tumors (ref: Labbé doi.org/10.1038/s41419-024-07133-3/). Furthermore, dual targeting of tumor-associated macrophages and microglia in glioblastoma models demonstrated significant antitumor effects, suggesting that immune modulation could be a viable strategy to counteract therapy resistance (ref: Liu doi.org/10.1172/JCI178628/). These findings emphasize the need for a multifaceted approach to address tumor heterogeneity and resistance, integrating molecular insights with therapeutic innovations to enhance treatment efficacy.

Innovations in radiotherapy techniques have shown promise in improving treatment efficacy and patient outcomes. A randomized trial on partial breast irradiation (PBI) demonstrated acceptable cosmetic outcomes with two different regimens, paving the way for further phase III trials to confirm these findings (ref: Kim doi.org/10.1200/JCO.24.00600/). Additionally, the combination of induction chemotherapy followed by chemoradiotherapy in cervical cancer patients resulted in significantly improved progression-free and overall survival rates, with hazard ratios of 0.765 and 0.760, respectively (ref: McCormack doi.org/10.1016/S0140-6736(24)01438-7/). Moreover, the efficacy of sonodynamic therapy combined with radiotherapy for brainstem gliomas was explored, revealing favorable safety and preliminary therapeutic potential (ref: Huangfu doi.org/10.1002/ijc.35218/). These advancements highlight the importance of refining radiotherapy techniques and integrating them with other treatment modalities to enhance therapeutic outcomes in various cancer types.

The exploration of molecular mechanisms underlying cancer progression has gained momentum, particularly in understanding the interplay between cancer and the nervous system.
