Table 4

Survival of patients with single or multiple primary melanomas.

Study	Number of patients SPM/MPM	Overall survival (OS) or; mortality rate (MR) (5 y); SPM/MPM	Conclusion
Rowe et al. 2015 [20]	1068/190	3.0%/6.8% () (melanoma specific mortality)	Increased mortality risk for patients with MPM compared to SPM.
Kricker et al. 2013 [19]	2372/1206	13.56 versus 2.93 (hazard ratio)	Relative fatality risk was higher for a thick SPM than for a thick MPM.
Savoia et al. 2012 [4]	4938/270	65%/80% (OS)	Better overall survival for patients with MPM.
Bower et al. 2010 [5]	2506/48	80%/95.3% (OS)	Patients with MPM had better overall survival.
Ferrone et al. 2005 [3]	4484/385	15.8%/5.6% (MR)	Better prognosis for patients with MPM.
Doubrovsky and Menzies 2003 [14]	5250/298		Survival of patients with MPM is superior to survival of patients with SPM.
Slingluff Jr. et al. 1993 [25]	236/?	31%/25% (MR)	Not reduce survival for patients with MPM.
