Radiation induced brachial plexopathy in head and neck cancer patients treated with definitive radiotherapy and correlation with disease characteristics and dosimetric parameters.

Background: Definitive concurrent chemoradiotherapy (CRT) is the standard of care in advanced stages of head and neck cancer (HNC). With evident increase in survival rate there is also simultaneous increase in toxicity affecting the quality of life. One of the less researched late toxicity is radiation induced brachial plexopathy (RIBP).

A Case of Radiation-Induced Brachial Plexopathy Below the Tolerance Dose.

This case report details a rare instance of radiation-induced brachial plexopathy (RIBP) occurring below the typical tolerance dose in a 55-year-old woman following chemoradiotherapy for apical non-small cell lung carcinoma. Despite receiving a radiation dose considered safe (47-48 Gray in 25 fractions), she developed sensory abnormalities and motor weakness in the right upper limb. The diagnostic distinction between RIBP and tumor recurrence was achieved using MRI, which showed characteristic features of radiation-induced damage.

The Role of Surgery in the Management of Radiation-Induced Brachial Plexopathy.

Radiation-induced brachial plexopathy (RIBP) is a rare long-term complication of radiation therapy often causing pain, motor deficit, and overall quality of life reduction for affected patients. While a standard treatment for RIBP is yet to be established, management consists mostly of symptom management through the use of medications and physical therapy. There is a lack of evidence regarding the efficacy of surgical treatment.

The role of surgery in the management of radiation-induced brachial plexopathy: a systematic review.

This systematic literature review of the clinical characteristics of radiation-induced brachial plexopathy and outcomes after intervention includes 30 trials with 611 patients. The mean radiation dose to the brachial plexus was 56 Gy, and the mean duration of radiation was 4 weeks. The mean time from radiation to the onset of symptoms was 35 months.

Radiation-induced inferior brachial plexopathy after stereotactic body radiotherapy: Pooled analyses of risks.

Introduction: Radiation-induced brachial plexopathy (RIBP), resulting in symptomatic motor or sensory deficits of the upper extremity, is a risk after exposure of the brachial plexus to therapeutic doses of radiation. We sought to model dosimetric factors associated with risks of RIBP after stereotactic body radiotherapy (SBRT).

Methods: From a prior systematic review, 4 studies were identified that included individual patient data amenable to normal tissue complication probability (NTCP) modelling after SBRT for apical lung tumors.

Hypofractionated Stereotactic Radiation Therapy Dosimetric Tolerances for the Inferior Aspect of the Brachial Plexus: A Systematic Review.

We sought to systematically review and summarize dosimetric factors associated with radiation-induced brachial plexopathy (RIBP) after stereotactic body radiation therapy (SBRT) or hypofractionated image guided radiation therapy (HIGRT). From published studies identified from searches of PubMed and Embase databases, data quantifying risks of RIBP after 1- to 10-fraction SBRT/HIGRT were extracted and summarized. Published studies have reported <10% risks of RIBP with maximum doses (D) to the inferior aspect of the brachial plexus of 32 Gy in 5 fractions and 25 Gy in 3 fractions.

Outcome of Nerve Grafting for Radiation-Induced Brachial Plexopathy.

Background: There is no consensus on the optimal treatment for radiation-induced brachial plexopathy (RIBP).

Objective: To present our experience of using nerve resection and autografting as a treatment strategy for this challenging condition.

Methods: From September 2014 to January 2020, 8 patients with RIBP were treated with segmental nerve resection and autografting, with or without other supplementary procedures.

Late-onset radiation-induced brachial plexopathy.

The late-onset variant of radiation-induced brachial plexopathy is most often seen after treatment for breast or lung cancers. It has an insidious onset, with symptoms noted years after receiving radiotherapy, and the condition gradually continues to deteriorate with time. We present the case of an elderly man who we saw in view of worsening paraesthesias and weakness of his left arm with associated prominent muscle wasting along the left shoulder girdle.

Radiation-Induced Brachial Plexopathy in Patients With Breast Cancer Treated With Comprehensive Adjuvant Radiation Therapy.

Purpose: Our purpose was to describe the risk of radiation-induced brachial plexopathy (RIBP) in patients with breast cancer who received comprehensive adjuvant radiation therapy (RT).

Methods And Materials: Records for 498 patients who received comprehensive adjuvant RT (treatment of any residual breast tissue, the underlying chest wall, and regional nodes) between 2004 and 2012 were retrospectively reviewed. All patients were treated with conventional 3 to 5 field technique (CRT) until 2008, after which intensity modulated RT (IMRT) was introduced.

Treatment of radiation-induced brachial plexopathy with omentoplasty.

Radiation-induced brachial plexus neuropathy (RIBPN) is a rare and delayed non-traumatic injury to the brachial plexus, which occurs following radiation therapy to the chest wall, neck, and/or axilla in previously treated patients with cancer. The incidence of RIBPN is more common in patients treated for carcinoma of the breast and Hodgkin lymphoma. With the improvement in radiation techniques, the incidence of injury to the brachial plexus following radiotherapy has dramatically reduced.

Pulsed Radiofrequency Ablation: An Alternative Treatment Modality for Radiation-Induced Brachial Plexopathy.

Radiation therapy is used as a form of treatment for various neoplastic diseases. There are many potential adverse effects of this therapy, including radiation-induced neurotoxicity. Radiation-induced brachial plexopathy (RIBP) may occur due to the fibrosis of neural and perineural soft tissues, leading to ischemic damage of the axons and Schwann cells.
