Now in her 40s, she reconciled herself to a lifetime of long pants, compression hose and a nightly, hours-long bout with an electric pump to keep the swelling down. She said her lymphedema made her feel like “a freak.”
But now, millions of people like Hanson may have a new treatment option. Researchers from Stanford University and other institutions conducted two new pilot studies, and report that ketoprofen, a common anti-inflammatory drug, significantly eases swelling and other skin damage from lymphedema.
“For a long time I couldn’t talk to people about my lymphedema without crying because it’s something weird and obscure,” Hanson said in a university news release. “Now there is hope for people like me with this disease.”
A condition affecting millions
The prescription medicine ketoprofen is a cousin to over-the-counter nonsteroidal anti-inflammatory drugs such as ibuprofen ( Advil) and naproxen ( Aleve), said lead author Dr. Stanley Rockson, director of Stanford’s Center for Lymphatic and Venous Disorders.
But using it for lymphedema — which affects about 3 million people in the United States — appears to alleviate the burdensome condition, according to the small new studies.
Lymphedema has no cure. Current treatments include compression garments, electric pumps and massage therapy to move lymph fluid manually through tissues. Rockson said ketoprofen could be an important add-on to those treatments.
“What’s dramatic for me, having worked with lymphedema patients now for 30 years, is that the traditional thought about lymphedema is it progresses from fluid accumulation to progressive, structural, irreversible damage,” Rockson said.
“We’re gratified to see that these supposedly irreversible results are not irreversible,” he added.
Rockson and his colleagues undertook a pair of small trials. First, 21 lymphedema patients took a 75-gram dose of ketoprofen by mouth three times a day for four months. The researchers performed skin biopsies at the start of the trial and again four months later to measure disease severity.
Based on encouraging findings, the follow-up trial enrolled 34 lymphedema patients, with 16 receiving ketoprofen and 18 receiving a placebo drug. Ketoprofen recipients showed reduced skin thickness as well as improvements in other factors related to skin health and elasticity.
“After a couple of months, I remember going home one day and taking my compression stockings off and looking at my leg, thinking, ‘Wow, my skin is wrinkly, that’s so weird,'” said Hanson, who took part in the trials. “The skin wasn’t so taut or thick. It was more like normal.”
She stressed that in her case at least, ketoprofen is “not a cure,” but it has produced a real improvement.
“Over time, the swelling has gone down,” Hanson said. “It doesn’t make it go away, but it has been easier to take care of my leg.”
An ‘exciting’ new option
Rockson said researchers also got the impression that patients treated with ketoprofen experienced a significant decrease in infections, though the studies didn’t specifically analyze that aspect. The drug works by blocking an inflammatory pathway in the body, he noted.
Like other NSAIDs, side effects of ketoprofen can include gastrointestinal upset or bleeding. Lymphedema patients who’d like to consider taking ketoprofen should speak with their doctors and weigh their risk factors, Rockson said.
“It’s certainly an option,” he said, adding he still hopes to tweak the drug’s structure to better suit lymphedema specifically in the future.
“It will, for a majority of users, make lymphedema better and hopefully at least prevent progression. But there’s a list of adverse effects that need to be considered, so that needs to be an individual decision,” Rockson added.
Several experts who treat patients with lymphedema praised the studies for potentially providing a new option for this group.
“The lymphatic system is very complicated and there’s not a lot of research on how it functions,” said Lisa Marshall, director of oncology rehabilitation at the Graham Cancer Center and Research Institute at Christiana Care Health System in Newark, Del.
“We don’t have a lot of options … as lymphedema patients get to the chronic state. So the fact that there’s now a drug that could enhance our outcomes that we could use as an [addition] to our treatments is very exciting,” added Marshall, who played no role in the new research.
Dr. Shubhada Dhage is director of breast surgical services at NYU Winthrop Hospital in Mineola, N.Y., and also wasn’t involved with the new studies. She said she was “highly optimistic” about the results, though small numbers of patients were tested.
“How this [research] will translate and have an impact currently with lymphedema is yet to be known,” Dhage said. “If the doctors of a particular patient are on board with [prescribing ketoprofen], it might be worth trying.”
The studies were published Oct. 18 in the journal JCI Insight.WebMD News from HealthDay
