PURPOSE Leptomeningeal metastatic disease (LMD) is associated with poor prognosis and imposes severe symptomatic limitations on functional status and quality of life. In recent years, the range of diagnostic and therapeutic options available to patients with LMD has expanded, but the impact of these innovations on clinical characteristics and outcomes remains unclear. We conducted a retrospective study to define the LMD patient population, symptoms experienced, and the frequency of accessing specialty palliative care (PC) services, at a large tertiary referral center. METHODS We conducted a retrospective electronic medical record review on the basis of a convenience sample of 104 patients diagnosed and treated with LMD with dates of diagnosis between January 1, 2016, and October 1, 2022. Variables were generated on the basis of patient demographics, reported symptoms, and clinical course. Data were analyzed using Stata 16. RESULTS Of 104 patients in the analysis, the most common symptoms reported were headache and extremity weakness (52% of patients reported each). The mean number of weeks between LMD diagnosis and date of death was 41.4, with a median of 27.9 weeks, and a range of 1.4-143.4 weeks. Forty-five percent of patients had at least one documented visit with an inpatient or outpatient PC provider. CONCLUSION Patients with an LMD diagnosis face a high symptom burden. Our findings highlight that prognosis may be longer than what is typically quoted in the literature, but further study would be needed to understand this discrepancy. Fewer than half of the patients in our sample had a documented visit with a PC specialist, suggesting a missed opportunity in this population to connect with providers specialized in managing symptom burden and doing nuanced advance care planning.
