ACCEPTED MANUSCRIPT 2 To the Editor: While the introduction of numerous immunotherapy and targeted therapy agents has led
45
to improved survival in advanced-stage melanoma over the past decade, these therapies have been
46
associated with severe adverse effects. Further, the overall impact of these therapies on quality of life
47
(QoL) is yet unknown, and few studies have investigated differences in QoL attainment of melanoma
48
patients by stage and treatment status.

A consecutive sample of adults diagnosed with melanoma within the past 24 months was recruited from
51
Washington University School of Medicine clinics between June 2015 and June 2016. Eighty-seven
52
patients completed the Functional Assessment of Cancer Therapy – Melanoma (FACT-M), a validated
53
disease-specific QoL instrument.1 Using a validated mapping function, FACT-M scores were converted to
54
European Quality of Life-5 Dimensions (EQ-5D) scores, a generic health utility measure useful in
55
comparing to other populations.2 Patients were stratified by localized (stages 0-II) versus advanced
56
(stages III-IV) melanoma. Baseline comparisons were tested using ANOVA for continuous variables and
57
χ2 for categorical variables. Multivariate regression models, adjusted for demographic and clinical
58
variables, were used to estimate the association between melanoma stage and QoL outcomes. A series
59
of structural equation models were constructed to explore the extent to which systemic therapy status
60
mediated the relationship between melanoma stage and QoL. STATA version 14 (StataCorp, College
61
Station, Texas) was used for analyses.

Our melanoma patient population achieved a lower mean EQ-5D score than their peers in the U.S.
64
general population (0.76 vs. 0.87, respectively).3 Melanoma patients achieved similar scores to patients
65
with coronary artery disease (0.73), diabetes mellitus (0.76), hypertension (0.79), arthritis (0.79), lung
66
cancer (0.80), and breast cancer (0.82).3,4

Melanoma QoL
ACCEPTED MANUSCRIPT 3 Localized melanoma patients had significantly higher overall FACT-M scores than advanced-stage
69
patients and performed better on all subscales except those corresponding to social and emotional well-
70
being (Table 1). Thus, the QoL disparity between localized and advanced melanoma patients was
71
primarily a consequence of physical rather than psychological factors.
72
RI PT
68
In sequential multivariable regression models (Table 2), advanced stage and systemic therapy were
74
significant predictors of lower QoL. Mediation analyses demonstrated that systemic therapy is
75
responsible for 75.5% of the association between stage and FACT-M score. Further, patients on targeted
76
therapy had overall the lowest QoL attainment in comparison to other systemic therapies and those not
77
on systemic therapy. In contrast, patients receiving single-agent immunotherapy had similar QoL to
78
those not receiving systemic therapy. These results suggest immunotherapy may be better tolerated
79
than targeted therapy.

While statistically significant, the magnitude of the EQ-5D disparity between advanced and localized
82
melanoma patients (0.04) was smaller than the minimally important difference of the instrument (0.07-
83
0.09).5 This suggests that the therapy-mediated QoL decline in advanced relative to localized melanoma
84
was below the threshold for concluding that two scores yield clinically disparate QoL outcomes. Thus,
85
we propose that the overall QoL impact of modern systemic therapies is minimal and is likely to be
86
outweighed by their proven survival benefit.
