Background: Leptomeningeal disease (LMD) from melanoma is rapidly fatal with median overall survival between 6.9 weeks and 3.5 months. It is not known whether immune checkpoint inhibitors have a role in treating LMD. Case presentation: We report a 33-year-old male patient who developed LMD from a BRAF V600E-mutated melanoma brain metastasis, despite prior treatment with surgical resection, radiotherapy and dabrafenib/trametinib. He underwent whole brain radiotherapy with stereotactic radiotherapy to the lumbosacral spine, and was started on nivolumab, which led to prolonged remission lasting 2 years and 3 months, before disease progression and death. Conclusion: This is the first case report to highlight a potential long-term efficacy of radiotherapy and anti-PD-1 immunotherapy, in treating LMD from metastatic melanoma that is resistant to targeted therapy.

Abstract PURPOSE We investigated the long term impact of SRS and WBRT in two large prospective phase III trials. METHODS Patients with 1–4 BMs +/- resection were randomized to SRS or WBRT. Cognitive deterioration was a drop of >1 standard deviation from baseline in >2/6 cognitive measures (CM). Quality of life (QOL) scores were scored 0–100 point scale. CM and QOL scores were modeled using baseline adjusted Linear Mixed Models (LMM) with uncorrelated random intercept for subject and random slopes for time. Differences over time between groups and the effect of >2 cognitive scores with >2 SD change from baseline were assessed. RESULTS 88 patients were included with median follow up of 24 months. We observed decreasing CM over time (SRS: 4/6; WBRT: 5/6). Mean CM was significantly higher in SRS for Total recall and Delayed Recall at 3, 6, 9, 12 months. More patients in WBRT arm declined 1 SD in >1 and >2 CM at the 3, 6, 9, and 12 months. A 1 SD decline in >3 CM at 1 year was 21% SRS vs 47% WBRT (p=0.02). SRS had fewer patients with a 2 SD decline in >1 CM at every time point. SRS had fewer patients with a 2 SD decline at >2 and >3 CM. WBRT had lower QOL at 3 months, but switched to SRS having lower QOL at 24 months for PWB, EWB, FWB, FactG, BR, and FactBR (p< 0.05). A 2 SD decline in cognition decreased mean FWB by 6.4 units (95% CI: -11, -1.75; p=0.007) and decreased QOL by 5.1 units (95% CI: -7.7, -2.5; p< 0.001). CONCLUSIONS We report the first pooled prospective study demonstrating the long term outcomes of patients with BMs after cranial radiation. WBRT was associated with worse cognitive outcomes. Impaired cognition is associated with worse QOL.

e14004 Background: Brain metastases (BM) is one of the most feared complications of cancer due to substantial neurologic sequalae, neuro-cognitive morbidity and grim prognosis. In the past decade, targeted therapies and checkpoint inhibitors have resulted in meaningfully improved overall survival for a minority of these patients. Accordingly, there is a growing need to identify issues surrounding patient survivorship and to standardize physician practice patterns for these patients. To date, there has not been a well-conducted formal study to specifically explore these questions of survivorship and practice standardization for BM patients. Methods: Here, we present results from a cross-sectional survey in which we analyzed responses from 237 BM patients, 209 caregivers, and 239 physicians. Surveys contained questions about BM symptoms, discussion of BM diagnosis by the clinician, psychosocial concerns, available treatment options for BM, BM patient advocacy resources, and BM-specific clinical trials. Results: Our survey revealed compelling findings about current care of BM patients. There were discrepancies in the perceived discussion of the implications of the diagnosis of BM, from the patient/caregiver and physician perspective. Important topics, such as prognosis and worrisome symptoms, were felt to have been discussed more frequently by physicians than by patients or caregivers. In our physician survey, private practice physicians, compared to academic physicians, were significantly more likely to recommend whole brain radiotherapy (61.1 vs 39.7%; p = 0.009). Participation in a clinical trial was one of the least recommended treatment options. Many physicians (59.1% private; 71.9% academic) stated that BM patients in their care are denied participation in a clinical trial, specifically due to the presence of BM. The consensus among physicians, patients and caregivers was that the highest yield area for federal assistance is increased treatment and research funding for BM. Conclusions: Our hope is that these findings will serve as a basis for future quality improvement measures to enhance patient-physician communication and patient well-being, continuing medical education activities detailing latest advances in BM for oncologists, and lobbying efforts to the federal government in prioritizing BM research, clinical trials, and patient survivorship.

Little is known about the optimal sequencing of targeted therapy and immunotherapy in the treatment of patients with BRAFV600-mutated metastatic melanoma. BRAF/MEK inhibition often has the benefit of rapid disease regression; however, resistance is frequently seen with long-term use. Treatment with immune checkpoint inhibitors offers the potential for long-term response but displays a lower rate of objective response. The benefit of synergy between therapies is apparent; however, there is limited data regarding optimal sequencing in the treatment of advanced melanoma. We present the case of a 62-year-old gentleman with advanced BRAFV600-mutated melanoma who followed an unconventional treatment path. After progressing on single-agent vemurafenib, he had response to multiple modalities of immunotherapy before progression. After, he had a substantial response to multiple BRAF/MEK inhibitor rechallenges before developing resistance. The patient is now stable after a retrial of combination immunotherapy. Our case illustrates that with the right sequencing of therapy, meaningful clinical responses can be elicited with rechallenging of targeted therapy and immunotherapy in metastatic melanoma.

e23090 Background: Patients with metastatic melanoma (MMel) who achieve durable long-term responses to checkpoint inhibitors (CI) represent a new type of cancer survivor, but their long-term quality of life (QOL) is poorly described. We measured symptom burden and long-term QOL in MMel patients treated with CIs at Memorial Sloan Kettering Cancer Center (MSK). Methods: Between February and August 2018 we performed a cross-sectional survey of adult patients with MMel treated with CI at MSK beginning at least 12 months prior to this study. Surveys were self-administered online using RedCap. We assessed patient treatment experience and QOL using the PRO-CTCAE bank, EORTC, EQ-5D, and Fatigue Severity Scale. We performed chart abstraction to assess extent of cancer burden, ECOG status, Charlson Comorbidity Index (CCI), concurrent medical conditions, and immune-related adverse events (irAEs) developing during or after treatment. For analysis, we dichotomized age (< 65 vs ≥65) and months from CI initiation (< 25 vs ≥25). Results: We enrolled 107 patients (39% survey response rate); 106 completed surveys. Participants were 57.0% male and 93.5% white, with median age 60.5 years (IQR: 51.1, 67.5 years). 79.4% had a CCI of 0 at start of CI; preexisting autoimmune disorders were rare. Median time since CI initiation was 36.4 months (range: 14.2, 133.9 months). Median length of CI treatment was 7.3 months (IQR: 2.1, 24.3 months); 15 patients were on treatment at the time of survey completion. Among those off treatment at the time of survey completion, median time off treatment was 27.1 months (IQR: 16.7, 40.4 months). The most common irAEs were rash (34.6%), colitis (24.3%), thyroiditis (19.6%), hepatitis (18.7%), and hypophysitis (13.1%). irAEs did not differ by age. Few patients reported symptoms at time of survey, most commonly aching joints (18%), fatigue (14%), aching muscles (13%), and difficulty sleeping (11%). Few (< 12%) had difficulty with physical, role, emotional, cognitive, or social functioning and almost none (1%) reported anxiety, depression or pain on the EQ-5D. QOL was excellent, with a median of 83.3% on the EQ-5D global health score and no differences based on toxicities or time from treatment. Conclusions: Long-term survivors of MMel patients report few burdensome symptoms after CI therapy and have excellent QOL.

2524 Background: Postoperative radiosurgery (SRS) has been associated with up to 30% risk of subsequent leptomeningeal disease (LMD). We previously demonstrated that radiographic pattern of LMD (classical “sugarcoating” [cLMD] vs. nodular [nLMD]) in this setting is prognostic. The association between radiographic pattern of LMD, type of salvage treatment (tx), and neurologic death (ND) has not been well described. Methods: The records of patients (pts) with brain metastases (BM), of which 1 was resected and treated with adjunctive SRS, and who subsequently developed LMD were combined from 7 tertiary care centers. Pts with classically radiosensitive tumors or prior or planned whole brain radiotherapy (WBRT) were excluded. ND was defined as symptomatic CNS progression around the time of death without life threatening systemic symptoms or progression. Salvage radiotherapy (RT) for LMD was categorized according to use of WBRT vs. focal cranial RT. Results: The study cohort consisted of 147 pts, of which 125 had died with known cause, 107 also received LMD salvage tx, and 82 also had cranial MRI follow-up. The ND rate in the 125 pts who died with known cause was 79%; the rate in pts who underwent LMD salvage tx (n = 107) was 76%. Univariate logistic regression demonstrated radiographic pattern of LMD (cLMD vs. nLMD, odds ratio [OR] 2.9, p = 0.04) and 2nd LMD failure after salvage tx (OR 3.9, p = 0.02) as significantly associated with ND. The ND rate was 86% for cLMD vs. 68% for nLMD pattern. WBRT was used in 95% of pts with cLMD vs. 52% of pts with nLMD. In the nLMD cohort (n = 58), there was no difference in ND rate based on type of salvage RT (WBRT: 67% vs. focal cranial RT: 68%, p = 0.92). Second LMD failure (vs. not) was associated with higher ND in the nLMD cohort (77% vs. 52%, p = 0.02). Of the 26 pts with nLMD who experienced 2nd LMD failure, 7 had classical 2nd LMD, of which 100% experienced ND, and 19 had nodular 2nd LMD, of which 68% experienced ND (p = 0.09). Conclusions: LMD after surgery and SRS for brain metastases is a clinically significant event with high rates of neurologic death. Classical LMD pattern (vs. nodular) and 2nd LMD failure after salvage tx were significantly associated with higher risk of neurologic death. In the nodular LMD cohort, radiographic pattern of 2nd LMD may be associated with risk of subsequent neurologic death. Pts with nodular LMD treated with salvage focal cranial RT or WBRT had similar risk of neurologic death. Methods to decrease LMD and the subsequent high risk of neurologic death in this setting warrant investigation.

Purpose A multicenter phase II study was conducted to assess the efficacy of rituximab, methotrexate, procarbazine, and vincristine (R-MPV) followed by consolidation reduced-dose whole-brain radiotherapy (rdWBRT) and cytarabine in primary CNS lymphoma. Patients and Methods Patients received induction chemotherapy with R-MPV (five to seven cycles); those achieving a complete response (CR) received rdWBRT (23.4 Gy), and otherwise, standard WBRT was offered (45 Gy). Consolidation cytarabine was given after the radiotherapy. The primary end point was 2-year progression-free survival (PFS) in patients receiving rdWBRT. Exploratory end points included prospective neuropsychological evaluation, analysis of magnetic resonance imaging (MRI) white matter changes using the Fazekas scale, and evaluation of the apparent diffusion coefficient (ADC) as a prognostic factor. Results Fifty-two patients were enrolled, with median age of 60 years (range, 30 to 79 years) and median Karnofsky performance score of 70 (range, 50 to 100). Thirty-one patients (60%) achieved a CR after R-MPV and received rdWBRT. The 2-year PFS for this group was 77%; median PFS was 7.7 years. Median overall survival (OS) was not reached (median follow-up for survivors, 5.9 years); 3-year OS was 87%. The overall (N = 52) median PFS was 3.3 years, and median OS was 6.6 years. Cognitive assessment showed improvement in executive function (P < .01) and verbal memory (P < .05) after chemotherapy, and follow-up scores remained relatively stable across the various domains (n = 12). All examined MRIs (n = 28) displayed a Fazekas score of ≤ 3, and no patient developed scores of 4 to 5; differences in ADC values did not predict response (P = .15), PFS (P = .27), or OS (P = .33). Conclusion R-MPV combined with consolidation rdWBRT and cytarabine is associated with high response rates, long-term disease control, and minimal neurotoxicity.
