(SGB) in Men Treated for Prostate Cancer Improve Hot Flashes

Prostate Cancer Clinical Trial

Official title: Does Stellate Ganglion Blockade (SGB) in Men Treated for Prostate Cancer Improve Hot Flashes? A Pilot Prospective Cohort Study

Status Terminated

Clinical Trial Summary

Androgen Deprivation Therapy (ADT) is a critical component of advanced prostate cancer treatment but causes numerous adverse effects including decreased bone mass, decreased muscle mass, gynecomastia, erectile dysfunction, loss of sexual desire, depression, disordered sleep, urinary symptoms, and hot flashes (HF). HF are unpleasant paroxysmal episodes of flushing, sweating with vasodilation of the face, neck, and chest. These episodes can last for seconds to minutes and are often associated with night sweats, anxiety, and insomnia and have negative effects on quality of life.

Stellate ganglion blockade (SGB) with local anesthetic may be an effective treatment of HF in men on ADT, but has not been studied in any published clinical trials.

The stellate ganglion is a neural structure in the anterior cervical spine region and is part of the sympathetic nervous system. It has been injected safely in the practice of pain management for more than 50 years in cases of post herpetic neuralgia (shingles), complex regional pain syndrome (CRPS) and other painful neuropathies as well as some types of cardiac dysrhythmias.

Given the frequency and severity and interference of HF in men on ADT for prostate cancer, in addition to the negative effects HF impose on this patient population and a paucity of effective treatments, finding alternative treatments for HF in this population is needed.
