Insomnia is a common concern for people who have cancer as well as survivors. Jun Mao, Chief of the Integrative Medicine Service at MSK, says there are natural ways that people can reduce their sleeplessness. He will present the findings at the American Society of Clinical Oncology’s annual meeting.
A study led by Memorial Sloan Kettering researchers showed that acupuncture and cognitive behavioral therapy were effective ways for cancer survivors to reduce insomnia. Though cognitive behavioral therapy was found to be better than acupuncture, both options had long-lasting benefits for sleep problems.
“Up to 60% of cancer survivors have some form of insomnia, but it is often underdiagnosed and undertreated,” says Jun Mao, Chief of the Integrative Medicine Service at MSK. Dr. Mao led the study and will be presenting the results as part of the 2018 annual meeting of the American Society of Clinical Oncology. “Now, people have more choices to manage their insomnia.”
A Need for Relief
Dr. Mao set out to compare the two treatments because he knows insomnia is a frequent concern.
“People often say that cancer impacts sleep,” he says. “It’s hard for people to fall asleep, they wake up multiple times, and they feel very tired during the day. They’re looking for things that are not drugs to help them improve their sleep and quality of life.”
Medications are available to help people with insomnia, but Dr. Mao cautions that they don’t work over a long period and shouldn’t be taken long term because of side effects.
Comparing Two Insomnia Treatments among Cancer Survivors
Study participants, who were on average about 61 years old and about six years post-treatment, were seen over an eight-week period. They received either traditional Chinese acupuncture designed to treat insomnia, with an additional focus on pain, fatigue, and stress, or insomnia-specific cognitive behavioral therapy (CBT-I). CBT-I has two key components: sleep restriction and stimulus control. Sleep restriction limits the amount of time a person is in bed so that they can have higher quality and more efficient sleep. The result is that when they are in bed, they are deeply sleeping rather than tossing and turning. Stimulus control helps people stop doing anything that can make sleep difficult. This may include checking a smartphone or tablet before bedtime, reading a book, or watching TV in bed. Over time, the bed becomes a place only for sleep, not all kinds of activities.
Before and after the treatment period, people reported the severity of their insomnia on a 28-point index. Dr. Mao and his colleagues saw that overall, CBT-I reduced insomnia by 11 points (from about 19 on the scale to 8) compared with acupuncture, which decreased it by approximately 8 points (from 18 to 10). Since both proved successful, Dr. Mao says that giving people options for managing their insomnia is beneficial.
“Some people are very proactive about improving their sleep habits and prefer CBT-I, but there are quite a few who prefer acupuncture as a more passive or relaxing approach,” he says. “Cancer survivors have so much going on with their lives. It’s not like one size fits all.”
Survivors with mild insomnia were far more likely to respond to CBT-I (85%) than to acupuncture (18%). For those with moderate to severe insomnia before the study began, the response rate was similar (75% for CBT-I and 66% for acupuncture).
Both groups maintained the benefit for up to 20 weeks and had improved quality of life.
“Our trial showed that the effects are stable,” Dr. Mao says. “The beauty of CBT-I and acupuncture is that the effects endured without any additional sessions. Survivors don’t need ongoing CBT-I or acupuncture to treat insomnia.”Back to top
Looking Ahead: Increased Insomnia Awareness and Combining Therapies
People with insomnia don’t have to suffer in silence: They can work with their doctor to come up with a treatment plan that’s right for them.
“A lot of times, people don’t tell their doctors about their sleep issues,” Dr. Mao says. “And doctors are not knowledgeable enough about ways of treating insomnia that don’t involve medication.”
For MSK patients, acupuncture is available through the Integrative Medicine Service. CBT-I is available through MSK’s Counseling Center. Dr. Mao hopes to make both services available to people beyond MSK and is exploring the idea of combining the two therapies for even better outcomes.Back to top
