Background
Statins may restrict the cellular functions required for melanoma growth and metastasis.
Objectives
To determine whether long‐term statin use commenced before diagnosis of a primary melanoma is associated with reduced risk of melanoma recurrence.
Methods
We prospectively followed a cohort of patients newly diagnosed between 2010 and 2014 with localized tumour‐stage T1b to T4b melanoma in Queensland, Australia. We used Cox regression analyses to examine associations between long‐term statin use and melanoma recurrence for the entire cohort, and then separately by sex and by presence of ulceration, due to evidence of effect modification.
Results
Among 700 patients diagnosed with stage T1b to T4b primary melanoma (mean age 62 years, 59% male, 28% with ulcerated tumours), 94 patients (13%) developed melanoma recurrence within 2 years. Long‐term statin users (n = 204, 29%) had a significantly lower risk of disease recurrence than nonusers [adjusted hazard ratio (HRadj) 0·55, 95% confidence Interval (CI) 0·32–0·97] regardless of statin subtype or potency. Compared with nonusers of statins, risk of recurrence was significantly decreased in male statin users (HRadj 0·39, 95% CI 0·19–0·79) but not in female statin users (HRadj 0·82, 95% CI 0·29–2·27) and in statin users with ulcerated (HRadj 0·17, 95% CI 0·05–0·52) but not nonulcerated (HRadj 0·91, 95% CI 0·46–1·81) primary melanoma.
Conclusions
Statins commenced before melanoma diagnosis may reduce the risk of melanoma recurrence, especially in men and in those with ulcerated tumours. Clinical trial evaluation of the potential role of statins in improving the prognosis of high‐risk melanoma is warranted.
What is already known about this topic?
Statins may restrict the cellular functions required for melanoma growth and metastasis.
In our cohort of patients with high‐risk primary melanoma, long‐term statin users had a significantly lower risk of disease recurrence than nonusers.
What does this study add?
Statins commenced before melanoma diagnosis may reduce the risk of melanoma recurrence, especially in men and in those with ulcerated tumours. |
