With an aim to improve the lives of breast cancer survivors, global researchers have published a clinical guide on how and where to roll out evidence-based interventions to help prevent lymphoedema for millions of cancer survivors.

The distressing condition involves the accumulation of fluid in patients鈥� arms, resulting from damage or removal of lymph nodes during breast cancer treatment.

While there is currently no approach that can completely prevent the condition, researchers from in Hong Kong, and the collaborated with 64 global experts from 16 countries to develop guidance that can effectively help prevent lymphoedema after reviewing clinical trials.

Risk factors and prevention strategies

The study reviewed data from more than 60,000 patients with breast cancer-related arm lymphoedema involved in high-quality randomised-controlled studies to determine the best prevention strategies and risk factors that can cause the condition.

These risk factors include post-surgery radiotherapy, not monitoring patients鈥� arm volume one month after surgery, the number of lymph nodes removed and a high body mass index.

Compression sleeves, surgery to repair patients鈥� lymphatic systems and axillary reverse mapping (ARM) should be offered to people at risk of developing breast cancer-related arm lymphoedema (BCRAL), according to the study published by The Lancet in eClinicalMedicine.

Early intervention

Deputy Vice-Chancellor (Research) at Flinders University and the study鈥檚 co-senior author, Professor Raymond Chan, said about half of patients with breast cancer-related arm lymphoedema (BCRAL) develop this condition 12鈥�30 months after surgery, but it can also develop many years later.

鈥淥ur study has revealed evidence-based approaches to prevent BCRAL through approaches that take into account risk factors for patients, the availability of treatment options and the expertise of healthcare providers to ensure all patients are offered effective interventions, regardless of where they鈥檙e receiving care.

鈥淭his is the first study in the world to provide recommendations on the frequency and duration of surveillance, methods to detect early lymphoedema, thresholds for early intervention and types of treatments to offer depending on the degree of the condition. With this knowledge, these interventions can now be applied with confidence in clinical settings.鈥�

Endorsed by the Multinational Association of Supportive Care in Cancer, experts support the rollout of surveillance programs that can help prevent lymphoedema and have for the first time backed treatments using compression sleeves.

Compression sleeves are designed to provide controlled pressure that reduces the swelling on the arms associated with patients going through treatment with breast cancer-related arm lymphoedema.

Implementing surveillance programs

The lead author of the study, Dr Henry Wong, a clinical oncologist from the Oncology Department at the Princess Margaret 黑料吃瓜群网 in Hong Kong, said this study is the first to provide a detailed guide on how to implement surveillance programs and prophylactic compression sleeves for the prevention of BCRAL.

鈥淥ur consensus-based recommendations generated by an international team of experts provide a strong voice for healthcare teams worldwide to adopt a proactive approach in preventing this irreversible treatment-related complication.鈥�

Dr Matthew Wallen, a Senior Research Fellow within the Caring Futures Institute, and co-first author, said the strength of this clinical practice guidance document is in its robust multidisciplinary approach to preventing BCRAL.

鈥淏y identifying key risk factors, implementing early surveillance and providing recommendations around the latest treatment and management strategies, we can ensure people living with BCRAL are offered practical, timely and evidence-based care interventions.鈥�

鈥淥ur study sheds light on the best practices in the management of BCRAL and offers hope and empowerment to breast cancer survivors who may be devastated by their lymphedema,鈥� said Dr Adrian Wai Chan, a clinical research fellow in the Department of Radiation Oncology, Sunnybrook Health Sciences Centre, the University of Toronto and co-first author.
