Summary
This review highlights functional anatomy in prostate cancer treatment, focusing on preserving sexual function. Vessel-sparing radiotherapy shows promise in maintaining sexual health post-treatment while ensuring high cure rates.
Area of Science:
- Urology
- Radiation Oncology
- Medical Imaging
Background:
- Treatment selection for prostate cancer balances cure rates with quality of life.
- Previous studies link quality of life to treatment type (surgery vs. radiation).
- The functional anatomy approach emphasizes anatomic preservation for quality of life outcomes.
Purpose of the Study:
- To review functional anatomy-based preservation techniques for sexual outcomes in prostate cancer treatment.
- To assess the capacity of vessel-sparing radiotherapy in preserving sexual function.
- To explore individualized treatment approaches using MRI-visible tissue variants.
Main Methods:
- Review of current functional anatomy-based preservation techniques.
- Evaluation of vessel-sparing radiotherapy's impact on sexual function.
- Focus on MRI-based approaches for personalized prostate cancer treatment.
Main Results:
- Vessel-sparing radiotherapy can preserve sexual function in 90% of patients at 5-year follow-up.
- This approach maintains excellent cure rates for prostate cancer.
- Functional anatomy enables individualized treatments addressing genitourinary, rectal, and sexual functions.
Conclusions:
- Functional anatomy-based approaches, including vessel-sparing radiotherapy, are crucial for preserving sexual function post-prostate cancer treatment.
- Individualized treatment strategies informed by MRI can optimize both cure and quality of life.
- Preserving normal tissue variants is key to maintaining essential functions affected by treatment.
