Background Despite high rates of malnutrition and known links between malnutrition and adverse patient outcomes, nutrition support for patients with cancer is inconsistent. In mesothelioma, nutritional management is key for optimising physical functioning, quality of life and survival.

Aim To describe the perceptions and experiences of healthcare professionals regarding the nutritional management of patients with mesothelioma.

Method Semi-structured interviews were conducted with 14 healthcare professionals with experience in lung cancer and mesothelioma – eight cancer nurse specialists (CNSs) and six respiratory consultants. Data were analysed using reflexive thematic analysis.

Findings Participants recognised that nutritional issues are common in patients with mesothelioma and associated with a high symptom burden. They viewed early nutritional screening as important but approaches to screening varied. Participants found it challenging to obtain input from dietetics services and lacked training and resources in nutrition and diet. They viewed CNSs as having a central role in the nutritional management of patients but emphasised that more input from dietitians and physiotherapists was needed for CNSs to fulfil that role.

Conclusion Specific training, multidisciplinary input and better availability of resources are needed for CNSs to fulfil their role of providing optimal nutritional management for patients with mesothelioma.
