Radiotherapy Dose Modulation: Technological Evolution, Clinical Significance, and Future Perspectives in Precision Oncology

Abstract

Radiotherapy dose modulation represents one of the most transformative advances in modern oncology, enabling precise delivery of radiation to tumor tissues while minimizing exposure to surrounding healthy structures. The development of sophisticated techniques such as intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) has significantly enhanced dose conformity, treatment efficiency, and patient outcomes. This perspective article explores the conceptual foundations, technological evolution, and clinical implications of dose modulation in radiotherapy. It also discusses current challenges, including optimization complexities, uncertainties in dose calculation, and the balance between tumor control probability and normal tissue complication probability. Furthermore, emerging trends such as adaptive radiotherapy, artificial intelligence-driven planning, and biologically guided dose modulation are examined. By synthesizing current knowledge and offering forward-looking insights, this article highlights the central role of dose modulation in achieving precision medicine in cancer care.
