A multidisciplinary group-based survivorship intervention for those living with multiple myeloma: a feasibility study

While multiple myeloma continues to be an incurable cancer, advances in its understanding and management have led to significantly improved survival rates. Survivorship interventions for those living with multiple myeloma remain scarce, despite mounting evidence for multiple unmet support needs among multiple myeloma survivors. The current study aimed to evaluate the feasibility and preliminary effectiveness of a novel multidisciplinary group-based multiple myeloma survivorship intervention.

A mixed-method, repeated measures feasibility study was conducted within a routine cancer support service. Seven participants, aged over 18, who had a multiple myeloma diagnosis and were clinically assessed as suitable for the intervention by their haemato-oncologist, attended online for six weekly group sessions of physical exercise and self-management input, completing qualitative, physical and self-report measures at baseline, post-intervention and follow-up.

The intervention was deemed overall feasible, with relatively high uptake, participants describing it as largely acceptable and appropriate and providing recommendations for feasibility-enhancing intervention refinements. Findings regarding the preliminary effectiveness of the intervention were mixed. While qualitative analyses stressed the benefits of the intervention (e.g. peer support, connectedness, improved well-being) and large effect sizes were observed for most physical outcomes, no improvements in self-reported outcomes (i.e. quality of life, fatigue) were reported.

This study represents the first investigation of a promising novel survivorship intervention for those living with multiple myeloma, highlighting the importance of peer support in particular, on which future clinical trials, aiming to establish the intervention's effectiveness for routine care, will be able to build.
