In July 2010, 52-year-old Julie Barthels, a clinical director of a rape crisis center, woke up with a sharp pain in her right breast. When the pain persisted for more than a week, Barthels, who lives in Machesney Park, Ill., had a mammogram that revealed a mass in her breast of more than 2 centimeters. After a lumpectomy, Barthels was diagnosed with stage IIA breast cancer.
At the end of September, Barthels had additional surgery to remove her right breast and surrounding chest muscles and lymph nodes. She started chemotherapy a month later, and soon noticed swelling on her right side and in her upper arm. Eventually, she couldn’t stretch her arm over her head. Barthels had developed a condition called lymphedema, swelling that occurs when lymph fluid builds up in the body’s tissues, typically in the legs or arms. Lymphedema is a common complication following surgery to remove lymph nodes.
Barthels’ primary care physician referred her for occupational therapy. Barthels, who had recently undergone rehabilitation for injuries sustained in a motorcycle accident, was no stranger to this type of therapy.
In January 2011, she started meeting with an occupational therapist two to three times a week. The therapist used a special type of massage to decrease lymphedema swelling by moving lymph toward areas of the body where it can drain more easily. Over the course of four months, the therapist taught Barthels how to perform self-massage and advised her to use a compression shirt to manage her condition.
Barthels, now 61, says the exercises and techniques she learned helped her maintain her mobility even as she continued weekly chemotherapy treatments. “I have so much movement and flexibility that I would not have if I hadn’t learned to take care of myself,” she says.
Benefits of Cancer Rehabilitation
Occupational and physical therapy are components of care that fall under the wide umbrella of cancer rehabilitation, a field that aims to help cancer survivors improve their ability to function, return to daily activities and pastimes and boost quality of life.
Besides physical function, cancer rehabilitation can also focus on nutritional counseling and psychological counseling to help people manage pain, fatigue, depression and other challenges resulting from cancer and treatment.
Still, doctors may not always prescribe outpatient rehabilitation for cancer patients, even though many patients report having functional limitations that affect their daily lives.
In a study published in 2015 in the Journal of Geriatric Oncology, for example, 341 of 529 cancer survivors from ages 65 to 97 who were enrolled in a cancer registry reported at least one functional limitation to their doctors. Researchers randomly reviewed charts for 65 of these patients, and found that only 11 charts made mention of physical or occupational therapy.
“Rehabilitation has not been part of what we would call traditional cancer care,” says Nicole L. Stout, a physical therapist based in Sarasota, Fla., who is a project coordinator for the National Institutes of Health’s Cancer Rehabilitation Initiative. The initiative supports national and international efforts to improve cancer rehabilitation. “It’s critical that we find ways to better integrate rehabilitation services into the cancer care continuum, because patients do better with these interventions,” said Stout.
Some research supports this assertion. A 2010 study in the BMJ looked at 120 women with breast cancer whose surgery removed some of their lymph nodes. The researchers found that women who received education and physical therapy that included stretching, shoulder exercises and specialized massage therapy to circulate lymphatic fluid were less likely to have lymphedema than those who received only educational materials.
In addition, a review published in Rehabilitation Oncology in July 2018 found that a variety of lower limb exercises designed to strengthen and coordinate movement helped improve cancer survivors’ balance and reduce pain and tingling associated with neuropathy. The review also suggested that strength training had positive effects on balance, strength and quality of life.
When Barthels started having trouble walking due to pain and weight gain in spring 2011, her primary care physician gave her a referral for physical therapy, where she learned exercises to build balance and to strengthen her core muscles by working out on a balance ball. Her therapist also incorporated weekly aquatic therapy, using weights designed for use in the pool, which helped Barthels strengthen her hips and improve her gait.
“Just being in the warm water helped me to loosen and build muscles that had become stiff from so much time resting,” Barthels says.
Rehab Is Tailored for Individuals
Developing effective cancer rehabilitation programs can be challenging because each person may have different needs, says Rajesh Yadav, a rehabilitation physician at the University of Texas MD Anderson Cancer Center in Houston. Unlike patients recovering from an injury that can follow a linear path from illness to wellness, a cancer patient’s health may fluctuate over time.
“You have to have a handle on what’s going on with the cancer now,” Yadav says.
A rehabilitation physician like Yadav looks at the big picture of the person’s health, assessing physical function in addition to needs at work and home. “This patient is not just a tumor in one body part,” Yadav says. “We’re looking at a holistic view.”
Whether patients are learning how to deal with fatigue, getting familiar with using a walker or relearning how to drive, the goal is to help them do what they value, says Mackenzi Pergolotti, an occupational therapist and the director of research at ReVital Cancer Rehabilitation.
Pergolotti presented research in November 2017 at the International Society of Geriatric Oncology meeting in Warsaw, Poland, that showed that adults over 65 who received physical therapy to bolster strength and endurance, coupled with occupational therapy to address daily function, had better scores on mental health assessments compared to those who received standard care.
In addition, Pergolotti says, people who participated in the rehabilitation program in her study were more likely to say that they believed they could participate in the activities they value. “We think that may signify (that) older adults with cancer are more likely able to participate in what they find meaningful after rehabilitation,” she says.
Barriers to Access
Several factors can contribute to patients not accessing rehabilitation services.
Many health care providers tell cancer patients that treatments can be taxing. “In some ways, that’s helpful, because it helps them adjust their expectations,” says Kathleen Lyons, a rehabilitation scientist at Dartmouth-Hitchcock Norris Cotton Cancer Center in Lebanon, New Hampshire. But patients often feel overwhelmed by their illness, she says, and may not think to ask for rehabilitation therapies. “The onus is on us to make sure patients know there are options to treat their symptoms,” Lyons says.
Pergolotti’s experience suggests that older patients who live near a rehabilitation center are more likely to participate in a program than those who live farther away.
And even though inpatient and outpatient rehabilitation services are covered under Medicare, cost can be a barrier to accessing these treatments. A patient’s out-of-pocket costs will vary depending on their supplemental insurance. “It’s hard to nail down the exact cost because there are so many different types of supplementary insurance added to Medicare,” Pergolotti says.
Despite these challenges, cancer rehabilitation recommendations have made their way into professional guidelines.
In 2009, the National Comprehensive Cancer Network recommended physical or occupational therapy for cancer survivors who have lost function because of neuropathy. The American Society of Clinical Oncology has integrated rehabilitation into its treatment guidelines for head and neck cancers and breast cancer, as well as into guidelines for managing chronic pain. In April 2017, the American Occupational Therapy Association published professional guidelines for managing the needs of cancer patients and survivors.
