The current scientific field of exercise interventions in breast cancer is very large. Rehabilitation focuses on restoring or improving quality of life and thus on independence and participation in life. Hence, it is important to investigate exercise interventions in the setting of rehabilitation and aftercare. It is also necessary to determine the influence of physical activity or exercise therapy on the prevention of recurrence and mortality as well as on certain side effects of the disease and its medical treatment in rehabilitation. Physical activity in rehabilitation and aftercare is feasible and safe and can be used for various purposes. Against the background of reduced fatigue, chemotherapy-induced peripheral neuropathy, cancer-related cognitive impairment, arthralgia, lymphedema, recurrence, and mortality, as well as improved quality of life, different methodological approaches and evidence can be seen. Although the overall data availability has increased, there are gaps in study documentation as well as inadequate verification of scientific approaches in rehabilitation clinics and in everyday life.

Urinary incontinence is one of the most clinically relevant side effects in the treatment of prostate cancer patients. The aim of this systematic review and meta-analysis was to analyze the specifi...

Background: Secondary lymphedema (SL) is a possible side effect of breast cancer treatment. Current data describe a positive influence of exercise on upper lymphedema. This systematic review evaluates studies examining a potential preventive effect of exercise on SL incidence. Methods: A systematic literature search of PubMed, LIVIVO, and the Cochrane Library was performed. Results: 8 randomized controlled trials were included in the review. 3 studies investigated the effect of strength training, and 5 the effect of combined exercise therapy. 5 studies included participants without lymphedema at study entry, and 3 studies included both patients with and without lymphedema. The partly significant results showed that progressive strength training as well as combined dynamic exercise therapies consisting of physiotherapy, physical therapy, and/or kinesiotherapy are safe and can prevent SL. Onset as well as diagnosis of lymphedema were significantly decreased in 5 studies in the exercise group. Conclusion: All 8 studies included indicate a potential preventive effect of exercise on SL; however, further research is needed.

The diagnosis and treatment of cancer are highly stressful. Exercise therapy is often used to mitigate the adverse effects of treatment. But how good is the evidence base, and what has changed in recent years? In this narrative review, we present the current data and what it implies for the care of adults with cancer. This review is based on data from meta-analyses and systematic reviews concerning 16 relevant clinical endpoints (outcomes) of exercise therapy for cancer patients. The literature evaluated for this paper reveals that targeted exercise therapy is feasible and safe under appropriate supervision. It is highly effective for improving eight endpoints (anxiety, depression, fatigue, quality of life, physical function, secondary lymphedema after breast cancer, urinary incontinence, post-mastectomy pain syndrome in breast cancer) and may also have a beneficial effect on sleep quality, cardiotoxicity, and cognitive function. Less conclusive studies are currently available with respect to chemotherapy-induced polyneuropathy, nausea/vomiting, and bone health. There is currently insufficient data to suggest any benefit with respect to sexual function and risk factors for falling. The data shows that exercise therapy for cancer patients is safe and has manifold effects on selected clinically relevant parameters. Further studies should be performed regarding the possible utility of exercise therapy against treatment-related side effects for which the evidence is currently insufficient. On the basis of the currently available and already existing recommendations, quality-assured exercise therapy can be recommended to cancer patients suffering from a wide range of neoplastic conditions.
