Yet another study shows that Cancer patients who exercise regularly have a better recovery rate
But the idea that ‘one size fits all’ is NOT the best way to tackle exercise.
The NHS is woefully short of physiotherapists, and relies on ‘off-the-shelf- exercise plans, which work for some, but generally NOT for cancer survivors who have complex needs for lymphoedema, osteoporosis, neuropathy and generally getting on with their life. But just to get a referral for an assessment (not treatment) can take 3 – 4 months. GPs need to be chivied to ensure they mark referrals as URGENT – otherwise you can just get left behind.
Or end up going privately.
Sorry – if you are a coach potato, you’ve got to get up and get going. Latest studies from the Netherlands show that whilst undergoing adjuvant therapy those who exercise appear to be more physically active years after their treatment ends.
Weight gain is a nasty side effect of many drugs, but exercise has been proven to help reduce this, so you would imagine the NHS would be only too keen to support an exercise programme.
In addition, cancer patients who participated in an exercise program during therapy appeared to have less fatigue over both the short and long term, according to new findings from the Netherlands.
“The take-home message is that offering exercise during cancer treatment is recommended and has beneficial short- and long-term health effects,” said lead author Anne M. May, PhD, an associate professor of epidemiology at the University Medical Center in Utrecht, the Netherlands.
May noted that this study is the first to show that patients who are physically active during cancer treatment maintain higher levels of physical activity over the long term, which is highly beneficial for their health and well-being.
She explained that these results come from the long-term follow-up of the PACT trial, a Dutch study that investigated whether exercise during chemotherapy can reduce treatment-related side effects, including cancer-related fatigue.
“Cancer-related fatigue is one of the most distressing side effect of treatment,” said May, “and it can persist for many years after treatment. That is the reason why we studied whether exercise for people during treatment with chemotherapy would prevent patients from developing severe fatigue.”
If your GP isn’t keen to refer you, this Study has some weighty amunition to print out and hand to them.
The PACT study was a two-armed, multicenter randomized controlled trial that compared an 18-week supervised exercise program to usual care among 204 breast cancer patients and 33 colon cancer patients who were undergoing adjuvant treatment, including chemotherapy, of combined moderate- to high-intensity aerobic and strength training twice a week, The team previously reported short-term benefit from the exercise program, noting that patients in the intervention arm experienced less fatigue than those in the usual-care arm (BMC Medicine. 2015;13:121).
Now, here’s the science
A total of 128 patients were included in the follow-up after 4 years (intervention, n = 70; usual care, n = 58). Fatigue and physical activity levels had been assessed at baseline, at 18 weeks post intervention, at 36 weeks post baseline, and at 4 years post baseline.
May and her colleagues found that cancer patients in the intervention group experienced less physical fatigue at 4 years compared with patients in the usual-care group (-1.13, 95% confidence interval [CI], -2.45 to 0.20; effect size [ES] = 0.22), but this did not reach statistical significance.
Patients in the intervention group also engaged in significantly higher levels of moderate to vigorous total physical activity (141.77 min/wk: 95% CI, 1.31 – 281.61; ES = 0.22) after 4 years compared to those in the usual-care arm.
Patients who had participated in the exercise program reported engaging in moderate to vigorous physical activity 90 minutes a day on average, compared to 70 minutes a day reported by the usual-care group.
“We think that offering exercise during cancer treatment, including chemotherapy, should be recommended, as it has beneficial short- and long-term effects on health,” May concluded.
Consistently Shows Benefit
A growing body of evidence supports the premise that regular physical activity may play a protective role and decrease the risk for many types of cancer, and that it may also help temper the adverse effects of treatment. Studies have demonstrated that exercise regimens benefit cancer patients both when they are receiving active therapy and afterward.
At the press briefing, moderator Timothy Gilligan, MD, FASCO, a medical oncologist at the Cleveland Clinic in Ohio, pointed out how consistent the literature is regarding the benefits of physical activity. “Nutritional recommendations seem to change every year, but if you look at the research on exercise, it consistently shows many positive benefits for health,” he said.
“We want to get people to exercise, so It is interesting here that we saw a long-term effect on people’s physical activity level,” said Gilligan.
The study was supported by grants from the Dutch Cancer Society, the Dutch Pink Ribbon Foundation, and the Netherlands Organization for Health Research. The authors have disclosed no relevant financial relationships. Dr Gilligan has a relationship with Wellpoint.
