Background: Intensity-modulated radiation therapy (IMRT) is an advanced cancer treatment method that delivers high radiation doses to the target tumor while reducing damage to organs at risk (OARs). Given the complexity of this approach, multi-criteria optimization (MCO) is essential for balancing tumor coverage and reducing OAR doses. This study compared the performance of the multi-objective cuckoo algorithm (MOCA) and the genetic algorithm (GA) in optimizing IMRT treatment planning.
Methods: This study utilized data from 20 patients with head and neck cancer who underwent IMRT. Treatment planning was performed using MOCA and GA, and their performance was assessed based on dose-volume histograms (DVH), conformity index (CI), homogeneity index (HI), and computational time. Statistical tests were applied to analyze the data and compare the results between the two algorithms.
Findings: Results indicated that the MOCA algorithm performed better than GA. MOCA improved the mean tumor coverage (D95%) to 98.5% compared to 97.2% for GA (P < 0.01). Additionally, MOCA reduced the mean dose to OARs (Dmean) by 8% (P < 0.05) and performed computations 25% faster than GA. The conformity index (CI) was higher in MOCA, while the homogeneity index (HI) showed no significant difference between the two algorithms
Conclusion: Compared to GA, MOCA demonstrated superior performance in optimizing IMRT treatment planning. This algorithm enhances tumor coverage, reduces OAR dose exposure, and improves computational efficiency. However, further studies are required to validate its generalizability and clinical applicability for other cancer types. The findings of this study provide a foundation for improving therapeutic strategies in radiation oncology.
