Incidence and prognosis of brain metastases in cutaneous melanoma patients: a population-based study.
MELANOMA RESEARCH(2019)
摘要
Brain metastases (BM) from cutaneous melanoma are associated with poor prognosis. Population-based data describing the associated factors of incidence and prognosis of BM from melanoma are still lacking. We identified 121 255 melanoma patients diagnosed during 2010-2015 from the Surveillance, Epidemiology, and End Results program, and identified predictive factors for incidence and survival of BM patients by using multivariable logistic and Cox's proportional hazard regression, respectively. We identified 1547 patients with BM at the time of diagnosis of malignant cutaneous melanoma, representing 1.3% of the entire cohort and 35.4% of the subset with metastatic disease. The characteristics associated with higher BM incidence were male sex, age 40-60 years, melanoma location of face/head/neck, histologic type of nodular, higher T-stage, ulceration and extracranial metastases. The median overall survival and median cutaneous melanoma specific survival of patients with BM was 5 and 6 months, respectively. The relative factors of poor survival were older age and more extracranial metastatic sites. In summary, we provided insight into the epidemiology of BM from cutaneous melanoma. These results may provide significant help to improve the screening strategy of BM strategy and update the existing prognosis evaluation system.
