A new study has revealed that breast cancer patients who suffer from night awakenings and hot flashes may find some relief by a jab in the neck.
This nerve block, named "stellate" ganglion block, given in the neck of breast cancer survivors may reduce hot flashes and sleep dysfunctions that plague breast cancer survivors, especially those who take anti-estrogen medications. This will outdo conventional treatments, which are not fully effective and may carry serious risks.
Early research has indicated that the severity, frequency and duration of these hot flashes experienced by breast cancer survivors are much higher than those in menopausal women.
The study conducted by Eugene G. Lipov, MD, and Jaydeep R. Joshi, MD, of Advanced Pain Centers, Hoffman Estates (Chicago), Ill., focussed on the safety and efficacy of the stellate ganglion block in 13 breast cancer survivors. "Stellate" block gets its name by the star-shaped collection of nerves in the neck, which regulates body temperature and thus influencing quality of sleep.
In use since more than 60 years, the block is a numbing solution injection near the C6 vertebrae, which can be administered under either local anaesthesia or with "twilight" sedation. The safe placement of the needle is ensured by giving it by using fluoroscopy (guided X-ray). It takes only 10 minutes to perform in an outpatient setting.
"Estrogen-depleting drugs used in the fight against breast cancer often leave women's bodies defenseless against debilitating hot flashes and the sleep disturbances they cause. This small pilot study conducted in breast cancer survivors confirms our earlier research on healthy menopausal women that the stellate ganglion block can effectively 'shut off' these troubling symptoms. Since these symptoms are generally more severe in women who have undergone breast cancer treatment, the block is a significant arsenal in helping estrogen-depleted women feel better with few or no side effects," Lancet quoted Lipov, as saying.
