Associations of Pretransplant Melanoma With Outcomes After Organ Transplantation

Number of Events (%) Person-years Incidence Rate per 100,000 Person-years Unadjusted HR (95% CI) Adjusted HR (95% CI)
All-cause mortality
 No pretransplant melanoma (n = 184,703) 57,908 (31) 1,156,958 5,005 1.0 1.0
 Pretransplant melanoma (n = 336) 107 (32) 1,351 7,920 1.6 (1.3–1.9) 1.3 (1.0–1.5)
Melanoma-specific mortality
 No pretransplant melanoma (n = 184,703) 79 (0.04) 1,156,958 6.8 1.0 1.0
 Pretransplant melanoma (n = 336) 6 (1.8) 1,351 444 59 (26–136) 27 (11–64)
Incident posttransplant melanoma
 No pretransplant melanoma (n = 184,703) 787 (0.4) 1,153,994 68 1.0 1.0
 Pretransplant melanoma (n = 336) 11 (3.3) 1,330 827 10 (5.6–19) 5.4 (2.9–9.8)

Melanoma-specific death and incident melanoma models incorporate other death as a competing risk. Models are adjusted for sex, age at transplantation, non-Hispanic white versus other race/ethnicity, thoracic versus abdominal transplant, and year of transplantation.
