A supportive care intervention for people with metastatic melanoma being treated with immunotherapy: a pilot study...

Increasing numbers of metastatic melanoma (MM) patients are receiving immunotherapy treatment, including pembrolizumab, and the impact on their well-being is underexplored.

To assess the feasibility of a multimodal supportive care program to MM patients being treated with pembrolizumab.

This pre-post-test feasibility cohort study recruited MM participants treated with pembrolizumab: (i) supportive care intervention with usual care and (ii) usual care. The intervention comprised comprehensive medical assessment by supportive care physician (SCP), exercise physiologist (EP), and dietitian then a tailored supportive care program. Programs included exercise, dietary advice, non-invasive complementary therapies, and psychology consultation. Outcome measures included adherence, patient-reported symptoms, anxiety and depression, and toxicity. Descriptive data are reported.

We recruited 28 participants: 13 intervention and 15 control; three did not complete the study. Most were male, with median age 66 (range 42-85) years. All intervention participants completed baseline assessments with SCP, EP, and dietitian. Two missed follow-up with EP or dietitian. Symptoms most troubling at baseline were as follows: fatigue (n = 6), sleep (n = 6), general aches and pains (n = 5), and memory (n = 4). All intervention participants were prescribed 16 exercise sessions; 8 (50%) completed all; overall exercise adherence was 85%. Integrative therapies were accessed by 85% (11) participants. Immunotherapy-related adverse event rates were low and SCP consultation identified symptoms not captured by CTCAE 4.0.

A holistic supportive care intervention tailored to individual needs is feasible. The symptom burden in MM patients was low. Further investigation of the intervention is warranted, focused on populations with higher symptom burden to improve outcomes.
