Radiation-Induced Brachial Plexopathy: Current Understanding, Diagnosis, and Treatment Options

Area of Science:

• Oncology
• Neurology
• Radiotherapy

Background:

• Radiation-induced brachial plexopathy (RIBP) is a serious complication of cancer radiation therapy.
• It can manifest as early-onset (transient) or late-onset (chronic) conditions.
• RIBP affects patients treated for cancers of the lung, chest wall, head, neck, breast, and axilla.

Purpose of the Study:

• To review the incidence, pathophysiology, and diagnostic challenges of RIBP.
• To discuss current and potential treatment strategies for RIBP.
• To highlight the need for improved management targeting radiation-induced fibrosis.

Main Methods:

• Literature review of RIBP.
• Analysis of diagnostic approaches, emphasizing exclusion of neoplastic processes.
• Discussion of surgical and nonsurgical treatment modalities.

Main Results:

• Diagnosis of RIBP relies heavily on patient symptoms due to lack of objective scoring systems.
• Treatment options for RIBP are limited, with no significant advances in halting disease progression.
• Radiation-induced fibrosis is identified as a key target for future therapies.

Conclusions:

• Effective prevention and treatment of RIBP remain significant challenges.
• Further research is needed to develop targeted therapies for radiation-induced fibrosis.
• Improved diagnostic tools and therapeutic strategies are crucial for managing RIBP.
