Summary |
Objective |
To preliminarily explore death risk factors in primary melanoma patients.
Method |
Competing risk model analysis was used using a large sample public cohort and Cox proportional hazard model was compared.
Result |
In the competing risk model analysis, age, gender, ethnicity, stage, site, TMN stage and metastases were the independent risk factors of single primary melanoma (SPM) death. T stage had a particularly important impact on SPM death. T2 stage had a 3.212 times greater risk of interest event than T1 stage [hazard ratio (HR)=3.212, 95%CI: 2.994–3.446], T3 stage was 5.747 times greater than that T1 stage (HR=5.747, 95%CI: 5.337–6.187) and T4 stage had a 7.086 times than T1 stage (HR=7.086, 95%CI: 6.514–7.708). Gender, ethnicity, stage, site, T stage and brain and liver metastases were the independent risk factors of multiple primary melanoma (MPM) death. When some groups had a very high death rate or the reference group had a very low death rate in competing events, the results of Cox proportional hazard model may not be as accurate as the results obtained by fine-Gray regression model.
Conclusion |
Early diagnosis and therapy, and prevention of tumor progression and metastases of primary melanoma patients are important measures to improve its prognosis and survival.
