Multidisciplinary approaches to cancer cachexia: current service models and future perspectives

Abstract

Introduction: Cancer cachexia remains a complex unmet need in oncology, despite its high prevalence and high impact. Patients with cachexia experience numerous complications, including reduced tolerance and effectiveness of anti-cancer therapy, reduced mobility, and reduced functional status, leading to decreased quality of life and survival.

Areas covered: As the field moves toward greater consensus of definitions and measurements, we highlight tools currently available for identification and staging of cachexia, and the barriers that people with cancer face in timely identification and management of cachexia. Multidisciplinary cachexia service models have emerged to address practice gaps and needs identified by patients and clinicians. Person-centred approaches to cachexia care demonstrate promising improvements in patient outcomes, but controlled trials of service models are lacking.

Expert opinion: While significant advances have been made in the understanding of cachexia, future trials of clinical service models require standardisation of definitions and outcome measures, with more robust controlled studies to establish the efficacy of proposed best practice. We remain excited with the potential benefit of these innovative models and continue to advocate for implementation of dedicated multidisciplinary cachexia teams to ensure patients and their families receive the right support, in the right place, at the right time.
