چکیده
Background: Lung cancer is a leading cause of cancer-related mortality worldwide, underscoring the need for the development of more effective treatment strategies. Radiotherapy (RT), particularly intensity-modulated radiation therapy (IMRT), has enhanced tumor targeting while minimizing damage to healthy tissues. Nevertheless, radioresistance and challenges posed by the tumor microenvironment limit its efficacy.
Objective: Selenium-curcumin-polyethylene glycol 600 nanoparticles (Se-Cur-PEG NPs) analyzed as radiosensitizers in IMRT for lung cancer treatment.
Material and Methods: In this experimental study, Se-Cur-PEG NPs were synthesized and characterized for their potential as radiosensitizers.
Results: The in vitro toxicity of Se-Cur-PEG NPs against A549 lung cancer cells was evaluated using MTT assays, demonstrating a dose-dependent reduction in cell viability. The combination of Se-Cur-PEG NPs (50 µg mL-1) with IMRT (4 Gy) resulted in a significant enhancement in cell death compared to either treatment alone, indicating a strong synergistic effect (CI=1.21) and a notable sensitizer enhancement ratio (SER=2.5). Intracellular ROS generation analysis confirmed that Se-Cur-PEG NPs amplified IMRT-induced oxidative stress, contributing to increased cancer cell toxicity. 
Conclusion: These findings suggest that Se-Cur-PEG NPs hold promise as effective radiosensitizers, potentially improving lung cancer RT outcomes.
