A National Cancer Database analysis of the patterns of care for meningeal melanocytoma.

ABSTRACT

Aim: To evaluate demographics, treatment patterns, radiotherapy utilization and patient outcomes in meningeal melanocytomas. Materials & methods: The National Cancer Database was queried for meningeal melanocytomas diagnosed in 2002-2016. The effects of demographic, clinical and treatment variables were determined via Kaplan-Meier log-rank and Cox regression analyses. Results: The median and 5-year overall survival were 57.46 months and 48%, respectively. Patients earning ≥$48K showed improved survival (p = 0.0319). Radiotherapy and chemotherapy were utilized in 37.7 and 9% of patients, respectively. Conclusion: Income significantly affected survival. Surgery remains the mainstay approach. Radiotherapy was delivered in more than one-third of patients but did not impact survival. However, further analyses were limited by poor treatment modality information in the database.

Lay abstract Aim: To assess the impact of demographic, clinical and treatment factors on survival in patients with meningeal melanocytomas. Materials & methods: Biostatistical analyses were conducted on patients diagnosed with meningeal melanocytomas between 2002 and 2016 using data from the National Cancer Database. Results: The median and 5-year survival rate were 57.46 months and 48%, respectively. Patients with incomes ≥$48K showed improved survival (p = 0.0319). Radiotherapy and chemotherapy were administered in 37.7 and 9% of patients, respectively. Conclusion: Income was a critical factor in increasing patient survival. Surgery serves as the primary means for treatment, while radiotherapy and chemotherapy remain underutilized.
