Radiation Therapy for Benign Diseases and Premalignant Conditions

Area of Science:

• Oncology
• Radiation Oncology
• Benign Neoplasms

Background:

• Radiation therapy (RT) is traditionally used for malignant conditions.
• RT is increasingly recognized for its efficacy in managing select benign tumors and proliferative disorders.
• Noninvasive RT provides an alternative when surgery is not feasible, incomplete, or carries high morbidity.

Purpose of the Study:

• To review the role of radiation therapy in the management of specific benign conditions.
• To highlight RT as a valuable treatment modality for benign tumors and proliferative disorders.
• To discuss the application of RT in cases where surgical intervention is challenging or associated with significant risks.

Main Methods:

• Literature review focusing on the application of RT in benign conditions.
• Analysis of clinical scenarios where RT is a preferred or alternative treatment.
• Synthesis of evidence regarding RT's effectiveness in local control and symptom management for benign entities.

Main Results:

• RT demonstrates favorable responses and excellent local control for various benign entities.
• Paragangliomas (PGL), particularly glomus jugulare tumors, are prime examples where RT plays a critical role.
• RT shows promise in treating benign vascular and lymphoid disorders, including localized lymphoid lesions.

Conclusions:

• Radiation therapy is a valuable, noninvasive treatment option for select benign tumors and proliferative disorders.
• RT offers effective local control and symptom relief, especially when surgery is not optimal.
• The use of RT extends to conditions such as paragangliomas, pheochromocytoma, hemangiomas, and lymphoid disorders.
