SpaceOAR hydrogel complications in prostate cancer

Area of Science:

• Oncology
• Radiology
• Biomaterials

Background:

• SpaceOAR hydrogel is a biodegradable spacer used in prostate cancer radiation therapy.
• It aims to reduce rectal radiation dose and associated complications.
• Concerns exist regarding its potential complications and impact on imaging interpretation.

Purpose of the Study:

• To provide a pictorial review of imaging complications associated with SpaceOAR hydrogel use in prostate cancer patients.
• To illustrate the types of complications, their mechanisms, and their impact on patient outcomes and imaging.
• To enhance radiologists' and oncologists' understanding for improved patient management.

Main Methods:

• Pictorial review of imaging findings.
• Presentation of multiple case examples.
• Discussion of underlying mechanisms and clinical impact.

Main Results:

• SpaceOAR hydrogel can lead to specific imaging complications.
• These complications can affect the interpretation of subsequent imaging studies.
• Understanding these complications is crucial for accurate diagnosis and treatment planning.

Conclusions:

• Radiologists and oncologists must be aware of SpaceOAR hydrogel-related imaging complications.
• This knowledge aids in accurate interpretation of imaging and optimal patient management.
• Further understanding improves outcomes for prostate cancer patients undergoing radiation therapy.
