Combining Statins with Radiotherapy for Prostate Cancer: From Photon Experience to Proton Potential.

Area of Science:

• Oncology
• Radiation Oncology
• Pharmacology

Background:

• Statins show radiosensitizing potential in photon radiotherapy (RT), improving outcomes for prostate and other solid tumors.
• Current evidence is limited to photon-based RT, with statin synergy in proton therapy (PBT) being hypothetical.
• Proton therapy offers advantages in dose conformity and linear energy transfer (LET).

Purpose of the Study:

• To review and extrapolate the radiosensitizing effects of statins from photon RT to PBT.
• To propose a theoretical framework for enhanced therapeutic efficacy through statin-PBT combination.
• To highlight the need for preclinical and clinical validation of this combined approach.

Main Methods:

• Narrative review of existing literature on statins in RT.
• Extrapolation of mechanistic insights from photon RT to PBT.
• Theoretical analysis of potential synergistic interactions.

Main Results:

• Statins demonstrate radiosensitizing properties, reducing recurrence and toxicity in photon RT.
• A theoretical basis exists for statin-PBT synergy due to overlapping mechanisms and PBT advantages.
• No direct clinical data currently supports statin use with PBT.

Conclusions:

• Combining statins with PBT is a promising theoretical strategy to enhance cancer treatment efficacy.
• The proposed synergy is grounded in statin-induced radiosensitization and PBT's physical and biological characteristics.
• Systematic preclinical and clinical investigation is required before adopting statins with PBT in standard practice.
