Selecting the optimal radiation modality in prostate cancer.

Area of Science:

• Oncology
• Radiation Oncology
• Medical Physics

Background:

• Numerous radiation modalities exist for definitive localized prostate cancer treatment.
• Established clinical trials provide foundational treatment principles.
• Emerging data offer new strategies to enhance therapeutic ratios by improving tumor control and reducing toxicity.

Purpose of the Study:

• To critically appraise the literature on selecting optimal radiation therapy for localized prostate cancer.
• To guide clinicians in choosing appropriate radiation modalities based on risk stratification and emerging data.

Main Methods:

• Literature review and critical appraisal of existing studies on radiation therapy for prostate cancer.
• Analysis of data from classic clinical trials and recent research.
• Evaluation of risk stratification, hormonal therapy, genomic classifiers, molecular imaging, and multiparametric MRI.

Main Results:

• Optimal radiation therapy selection hinges on upfront risk stratification.
• Higher-risk disease warrants treatment intensification and multimodality approaches.
• Hormonal therapy use should be guided by prognostic information and tumor aggressiveness.
• Molecular imaging and multiparametric MRI inform treatment intensification and target delineation.

Conclusions:

• Personalized radiation therapy selection is crucial for localized prostate cancer.
• Risk stratification, genomic data, and advanced imaging are key to optimizing treatment.
• Multidisciplinary collaboration is essential for evidence-based, shared decision-making in prostate cancer radiation therapy.
