Cancer Treatment Centers of America Tulsa
Sleep Diagnostic Lab
The Sleep Diagnostic Center at Cancer Treatment Centers of America® (CTCA) treats a variety of sleep disorders among our patients. Sleep disturbances can occur in individuals with all types of cancer.
Cancer and sleep disorders
According to the National Cancer Institute, an estimated 45 percent of cancer patients experience sleep problems. Some risk factors associated with sleep disorders include:
Witnessed episodes of breathing that had stopped during sleep
Increased muscle mass
Anatomic abnormalities, especially for patients who had undergone radiation therapy
Enlarged tonsils and adenoids
Chronic nasal congestion
A family history of stroke, heart attack or diabetes
High blood pressure
Sleep apnea is a sleep disorder characterized by abnormal pauses in breathing, or instances of abnormally low breathing, during sleep. Sleep apnea and other sleep problems can lead to fatigue, poor concentration, irritability, anxiety and depression. Also, recent research reveals that the inadequate supply of oxygen that characterizes sleep apnea may promote increased vascular and tumor growth in cancer patients.
What’s involved in a sleep study?
If you experience symptoms of sleep apnea or other related sleep disorders, your doctor will refer you to the Sleep Diagnostic Center for a sleep study.
During your overnight stay, a specially trained technologist will apply sensors to your body and monitor your progress continuously throughout the night. The digital monitoring devices record your level of sleep and measure brain waves, eye movements, muscle tone, heart rate, respiration, blood oxygen levels and more.
If abnormalities are detected, the technologist will apply a breathing mask to find the treatment level necessary to correct your symptoms. Sometimes this cannot be done in the same night, so an additional study may be necessary.
Diagnosing sleep disorders
After your overnight stay, a board certified sleep disorder specialist will interpret the results, including the type and cause of your sleep condition. You will be evaluated for narcolepsy, obstructive sleep apnea, central sleep apnea, hypoxemia (low oxygen) and other sleep disorders.
There are over 90 sleep disorders listed in the latest edition of the International Classification of Sleep Disorders (ICSD). Some common sleep disorders include:
Insomnia (inability to fall asleep and stay asleep)
Sleep apnea (sleep-disordered breathing)
Restless legs syndrome
Disorders of the sleep-wake cycle
Sleep disturbances may be caused by the effects of tumor growth, certain cancer treatments and medications (e.g., opioids), and/or treatment-related side effects (e.g., pain, shortness of breath, GI disturbances, hot flashes, anxiety, depression).
Treating sleep disorders
After the sleep study is complete, we will evaluate the results and discuss your treatment options with you. Treatment of sleep disturbances may involve a combination of pharmacologic and non-pharmacologic approaches. Sometimes treating the cancer itself and/or treatment-related side effects resolves the sleep problem. Your doctor may also adjust your medications or treatment regimen.
Your doctor may refer you to see our mind-body medicine, naturopathic, respiratory, and speech pathology teams to provide treatment to improve your sleep. Treatment options may include cognitive behavior therapy, stimulus control therapy, ventilation therapy, relaxation techniques, naturopathic therapies and lifestyle changes such as establishing a sleep routine, changing sleep environment/habits, managing stress, anxiety and fatigue. Our speech pathology team may incorporate evidence-based therapies into your treatment plan, such as exercises to strengthen the muscles obstructing the airway, also known as myofunctional therapy.
The Sleep Lab at Southwestern
The Sleep Lab at CTCA at Southwestern Regional Medical Center helps treat sleep disorders so you can get the rest you need to fight the disease. Our Sleep Lab services are available Monday through Friday. Dr. Larry Altshuler is the Sleep Lab's head physician and Carla Rausch is the Manager.
“Quality sleep has a significant impact on helping our patients improve their overall quality of life. The Sleep Lab is a valuable adjunct in our efforts to combat a variety of symptoms from cancer and its treatment, including insomnia, fatigue, narcotic side effects and many more,” says Dr. Altshuler.
