Abstract Brain metastases (BM) are the most common tumors to affect the central nervous system (CNS). Treatment options have recently evolved with the use of new targeted therapies, immune checkpoint inhibitors, and increased access to clinical trials. We describe our institutional experience with a weekly tumor board dedicated to BM. METHODS We conducted a single-institution cohort study at an academic hospital. Attendance at tumor board included representatives from neuro-oncology, medical oncology, radiation oncology, neurosurgery, neuropsychology, and neuroradiology. We prospectively gathered data on patient demographics, clinical history, and tumor board recommendations. Patients were followed to assess treatment course and survival. The Kaplan Meier method was used to calculate time to progression. RESULTS A total of 49 patients were presented over 2 months. The median age at presentation was 63 yrs with a median ECOG of 1. The primary malignancy was 35% melanoma, 29% lung, 23% breast, the remainder other. Most patients had advanced, heavily pretreated disease: 69% had Stage IV disease with a median of 2 prior lines of systemic therapy, 73% had multiple BM, 39% had prior surgical resection of BM, and 57% had prior CNS radiation. Change in management was recommended in 26/53 case presentations, with active BM-directed therapy (surgery, radiation, systemic therapy) recommended in 25/26 patients. The median time to start active therapy was 7 days. Only 3 patients have died at a median follow-up of 62 days. 9 patients have progressed, with a median time to progression of 57 days. CONCLUSIONS Multidisciplinary BM tumor board provides unique opportunities in the management of complex BM patients in an era of rapidly evolving therapeutic options. Additional follow-up is needed to assess long-term outcomes.

e13585 Background: Brain metastases are the most common tumors to affect the central nervous system. Treatment options have recently evolved with the use of targeted therapies, immunotherapy, and increased clinical trials availability. We describe our institutional experience with a novel, weekly tumor board dedicated to brain metastases and its impact on treatment decisions and survival. Methods: We conducted a single institution cohort study at a large academic hospital with a dedicated center for CNS metastases. Attendance at tumor board included representatives from neuro-oncology, medical oncology, radiation oncology, neurosurgery, and neuroradiology. We prospectively gathered data on patient demographics, clinical history, and tumor board recommendations. Patients were followed to assess treatment course and survival. The Kaplan Meier method was used to calculate time to progression. Results: A total of 49 patients were presented over 2 months, with 4 patients presented twice. The median age at presentation was 63 yrs with a median ECOG of 1. The primary malignancy was 35% melanoma, 49% lung, 22% breast, the remainder other. Most patients had advanced, heavily pretreated disease: 69% had Stage IV disease at time of tumor board presentation with a median of 2 prior lines of systemic therapy, 73% had multiple brain metastases, 39% had prior surgical resection of brain metastases, and 57% had prior CNS radiation. The tumor board recommended a change in management in 26/53 case presentations: 5 surgery, 8 radiation, 9 medical therapy, 3 clinical trial, and 1 surveillance. Recommendations were followed in all except 4 cases due to patient preference and loss to follow-up. When active therapy was recommended, the median time to start was 7 days. Only 3 patients have died at a median follow-up of 62 days. 9 patients have progressed, with a median time to progression of 57 days. Conclusions: A multidisciplinary brain metastasis tumor board provides unique opportunities in the management of complex brain metastasis patients in an era of rapidly evolving therapeutic options. Additional follow-up is needed to assess long-term outcomes, and comparison to non-tumor board presented patients will be necessary.

2569 Background: ICIs (anti-PD-L1/PD-1/CTLA-4) are approved in multiple cancers. The impact of organ dys on the pharmacokinetics of ICIs is known, but associated clinical outcomes are not well characterized. We compared real-world (rw) clinical outcomes in ICI-treated pts by liver and renal function. Methods: This retrospective study used longitudinal, patient-level data from community practices in the Flatiron Health electronic-health record (EHR)-derived database. We included pts diagnosed with advanced cancers (NSCLC, renal cell, melanoma, gastric/esophageal, or head and neck) on or after 1/1/2011, treated with an ICI with follow-up through 12/31/2018 and with baseline liver or renal function results in the EHR ≤30 days prior to ICI start. Organ function was stratified as normal, mild, moderate, or severe dys based on NCI CTCAE. We computed unadjusted median estimates for rw time to treatment discontinuation (rwTTD) for any reason and overall survival (OS) across baseline groups using the Kaplan-Meier method. Results: Of 15,979 pts, we identified 12,978/12,840 pts with evaluable renal/liver function, respectively; median follow-up was 5.1 mos and median age was 69.0 yrs (IQR: 61.0, 76.0) for both. Most pts had NSCLC (69.4/69.0%), were men (60.1/60.0%), white (73.5/73.6%), and diagnosed at stage IV (58.7%/58.6%). Most ICI was given in 1st-line (42.3/42.1%) (outcomes in Table). Conclusions: Pts with categorically worse baseline liver function had progressively worse on-treatment outcomes, including shorter OS, which differed from trends in renal dys. Whether baseline dys is prognostic or predictive of ICI outcomes should be further investigated in addition to reasons for discontinuation.

The Impact

2081 Background: Patients (pts) with brain metastases (BM) have a poor prognosis and limited treatment options. Approximately 40-50% of pts with NSCLC will develop BM during the course of their disease. A better understanding of the pathobiology of BM and the development of targeted agents hold promise for improved prophylaxis and therapy of BM which could have significant impact on disease progression and pt's survival. Vascular Endothelial Growth Factor has been implicated in setting up a metastatic niche allowing cells to seed and grow in the brain parenchyma. Inhibition of this signaling has been studied and shown to be effective in reducing BM in animal models. Methods: The objective of this retrospective study was to determine whether bevacizumab decreases the incidence and or the recurrence of BM in pts with NSCLC. We retrospectively identified NSCLC pts with and without BM treated with bevacizumab. The primary endpoint was the proportion of patients who developed BM on or after bevacizumab therapy. Secondary endpoints were rate of local or regional recurrence after stereotactic radiosurgery (SRS). Occurrence of BM was evaluated by retrospectively reviewing MRI and or CT scans. Results: A total of 30 pts with stage IV non-squamous NSCLC who had no BM at diagnosis treated with bevacizumab (Non-BM group, NBMG) and 85 pts with non-squamous NSCLC who had BM and underwent SRS (BM group, BMG) were studied (46%M; median age 60 years (range 32-84). In the NBMG, 28% of pts developed BM. Median time to development of BM was 10.5 months. In the BMG, 4 pts were treated with bevacizumab following SRS. Of these 4 pts, 3 pts (75%) had no recurrence while 1 pt (25%) developed local then regional recurrence at 7 and 9 months, respectively. Of the remaining 81 pts who underwent SRS but never received bevacizumab, 27% of pts had local recurrence and 41% had regional recurrence at median time of 4 and 4.5 months, respectively. Conclusions: Bevacizumab may have a role in the treatment of NSCLC in regards to development and recurrence of brain metastases. These results support the need for further prospective investigation in a larger patient population with matched controls.

Extracranial Metastases

1090 Background: Despite advances in systemic therapies and improved overall survival of metastatic breast cancer (MBC) patients, the development of brain metastases (BMs) remains a challenging complication that affects quality of life and increases morbidity and mortality. Current clinical practice guidelines recommend local treatment of BMs without changing systemic therapy (CST) in patients with stable systemic disease. Methods: We retrospectively investigated the impact of CST (when applicable as per treating physician’s discretion) after diagnosis of the initial 1-3 BMs on the patient’s progression-free survival time (PFS), defined as time to death, to a second BMs or to extracranial metastases. All MBC patients with 1 to 3 BMs only (without extracranial disease) treated at our institution between 2002 and 2017 were identified. For each patient, full information on follow-up and administered therapies were mandatory for inclusion. Hazard ratios (HR) were calculated using the Cox proportional hazard model. We also computed the restricted mean survival time (RMST) up to 5 years of follow-up. Results: Among the 2645 patient with BM treated at our institution, 80 were included for analysis. In regards to primary BMs management in patients, 46 of 80 (57%) were treated by radiation therapy, 6 of 80 (7.5%) underwent surgical resection, and 28 of 80 (35%) were managed by a combination of surgery and radiation therapy. All patients had staging imaging documenting lack of extracranial metastases at the time of local therapy of BMs. Following the primary management of BM, we observed that providers changed systemic therapy in 32 of 80 (40%), defined as the CST group. CST included both initiation of therapy in 16 of 80 (20%) and switching of adjuvant therapy in 16 of 80 (20%). Median PFS among CST was 7.7 months vs. 7.2 months among no CST (HR = 0.855, 95% confidence interval (CI) 0.53-1.38, p = 0.52). 5-year RMST for the CST group was 16.6 months vs. 12.8 months in no CST group. The difference of 3.8 months (95% CI 4.3-11.8) was not statistically significant. Conclusions: Patients with 1-3 BMs without extracranial disease had a median PFS close to 7.5 months after local therapy. Consistent with current standard of care of maintaining the same systemic therapy approach upon developing isolated BMs, our findings did not demonstrate a significant difference in PFS between patients who experienced a change in systemic therapy compared to those who did not.

Multidisciplinary Tumor Board

e19248 Background: International guidelines for genitourinary cancers recommend treatment decisions by a multidisciplinary tumor board (MTB). The benefits of a MTB include greater accuracy in staging and in the probability of receiving care in compliance with international clinical practice guidelines, greater access to clinical trials, better communication between treating physicians and cost-effective care with greater patient satisfaction, which could translate into better outcomes. Our objective was to assess the impact of a MTB in the management of patients with genitourinary tumors in a tertiary referral university center of México. Methods: We performed a retrospective analysis of all cases presented to the Genitourinary Tumor Committee of our hospital from March to August 2019. Results: A total of 84 patients were included in the analysis; of these 80% were men with a median age of 61 years. Of all the cases, 68% were first-time presentations with a median time from evaluation to presentation of 4 days. The most frequently discussed diagnoses were prostate, urothelial and renal cancer, each corresponding to about 28% of the sample. Forty-six percent of the cases presented were in metastatic disease. The median time for discussion of each case after its presentation was 10 minutes. Changes were made in the clinical stage and treatment plan proposed by the most responsible physician in 4% and 46% of the cases, respectively, achieving a unanimous consensus in 88%. After the MTB session, 29 patients were lost to medical follow-up and were not subsequently evaluated. Among the 55 patients who underwent reassessment, the recommendations of the MTB were applied in 92%. Conclusions: Discussion of urologic oncology cases at the MTB led to a change in the treatment plan in almost half of the patients. Although MTBs are an increasingly common practice in Mexico, this is the first study that describes the impact that these sessions have on the management of genitourinary tumors in our population. The high rate of loss to medical follow-up remains an important problem in developing countries, negatively affecting the prognosis of these patients.

The Impact

The median overall survival (OS) and local control (LC) of patients with melanoma brain metastases (MBMs) are poor even with immune checkpoint inhibitors and/or radiotherapy (RT). The aims of the study were to evaluate the association and timing of stereotactic radiotherapy (SRT)/radiosurgery (SRS) performed with the CyberKnife® System and ipilimumab (IPI). A total of 63 MBMs patients were analyzed: 53 received RT+IPI and 10 RT alone. Therefore, the patients were divided into four groups: RT PRE-PI (>4 weeks before IPI) (18), RT CONC-IPI (4 weeks before/between first and last cycle/within 3 months of last cycle of IPI) (20), RT POST-IPI (>3 months after IPI) (15), and NO-IPI (10). A total of 127 lesions were treated: 75 with SRS (one fraction) and 24 with SRT (three to five fractions). The median follow-up was 10.6 months. The median OS was 10.6 months for all patients, 10.7 months for RT+IPI, and 3.3 months for NO-IPI (p = 0.96). One-year LC was 50% for all patients, 56% for RT+IPI, and 18% for NO-IPI (p = 0.08). The 1-year intracranial control was 45% for all patients, 44% for RT+IPI, and 51% for NO-IPI (p = 0.73). IPI with SRS/SRT in MBMs treatment could improve LC. However, the impact and timing of the two modalities on patients’ outcomes are still unclear.

11548 Background: The mainstay therapy of operable STS remains surgery, which may include (neo)adjuvant therapies. Within the TSP, marginally inoperable STS are often treated with sequential chemo (CTX) and radiation (RT) therapy, followed by surgery (SX). Herein we present our experience of multi-modality therapies for marginally inoperable STS patients (pts). Methods: This was a dual-center, single program, retrospective review. Pts were included if deemed to have marginally inoperable primary or recurrent STS, as determined at the TSP tumor board. Pts included must have had CTX with the intent of having RT and SX after. Pts demographics, treatment details and clinical outcomes data were collected. Relapse free survival (RFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Multivariate analysis of the influence of disease characteristics and treatment on outcomes was assessed using Cox regression. Results: From June 2005 to May 2019, 75 pts were identified. Median age was 52 years (range 16-72). Pts were predominantly male (55%). Histological subtypes included dedifferentiated liposarcoma (29%), leiomyosarcoma (27%), synovial sarcoma (19%) and others (25%). Primary tumor was located in the retroperitoneum (48%), extremity (23%), pelvis (12%), thorax (9%), and other sites (8%). All pts had doxorubicin and ifosfamide CTX (median 4 cycles; range 1-6), while RT dose delivered was 50.4Gy/28 fractions in 58 (77%) of cases. Twenty three pts (31%) achieved partial response, 40 pts (53%) had stable disease and 12 pts (16%) had progression of disease (PD) on CTX, of which half (8%) did not undergo further treatment. Nine pts (12%) underwent CTX followed by SX due to significant response, 9 pts (12%) underwent CTX and RT without SX due to persistent tumor unresectability or PD. The final 50 pts (67%) completed multi-modality treatment (CTX, RT & SX). Overall, 59 pts (79%) had SX; negative margins were achieved in 53 (71%). 19 pts (25%) had postoperative complications, causing death in 2 pts (2.7%). With a median follow-up of 72 months, median RFS and OS were 26.9 months (95% CI: 0-86.0), and 65 months (95% CI: 13.5-116.4). Extremity location was associated with superior RFS (median not reached [NR], HR 0.28 95% CI 0.09-0.83, p = 0.022), and OS (median NR, HR 0.29 95% CI 0.09-0.90, p = 0.032). Receipt of RT was associated with superior RFS (median NR, HR 0.23 95% CI 0.10-0.52, p < 0.001); and OS (median NR, HR 0.21 95% CI 0.09-0.50, p < 0.001). Pts who had PD after CTX were associated with poor outcomes - RFS (median 4.7 months, HR 2.03 95% CI 0.61-6.76, p = 0.24); and OS (median 21.9 months, HR 2.48 95% CI 0.73-8.47, P = 0.144). Conclusions: Multi-modality approach resulted in successful resection for most pts with marginally inoperable STS. Extremity location and RT administration were associated with better RFS and OS, while progression on CTX confers worse survival outcomes.

9543 Background: mMCC is a rare, aggressive neuroendocrine cancer which often occurs in older patients (pts) with multiple comorbidities. While initial response rates to ICI are high, optimal treatment duration, durability of response after treatment cessation and response to retreatment with ICI is unknown. Methods: mMCC pts from 12 international centres who received at least one dose of ICI and subsequently stopped treatment without progression for a minimum of 12 weeks were studied. Demographics, disease characteristics and treatment course were examined. Results: 40 pts with mMCC were included. Pt characteristics are summarised in Table. Median time on treatment was 13.5 months (range 1 to 35). Median time to best response was 4.5 months (range 1 to 17) and median time receiving treatment after best response was 8 months (range 0 to 29). 25 pts (63%) stopped primarily due to being in a complete or partial response (CR or PR), 9 (23%) due to toxicity and 6 (15%) due to other reasons, primarily pt choice or comorbidities. At time of discontinuation, 30 pts (75%) were in a CR, 8 (20%) in a PR and 2 pts (5%) had stable disease (SD). After a median follow up of 12 months from discontinuation, 14 pts (35%) have progressed (PD); 5 (36%) at a previous site, 5 (36%) at a new site and 4 (29%) at both. PD occurred after a median of 5.5 months (range 4 to 29) off treatment. 4 pts (29%) had a CNS recurrence, none of whom previously had CNS involvement. Pts in CR at time of discontinuation were less likely to progress (CR: 26% PD vs non-CR: 67% PD, p=0.044), but still had a considerable rate of PD (CR: 26%, PR: 57%, SD: 100%). Those who progressed had numerically less cycles of ICI prior to treatment cessation (17 vs 32, p>0.05). Baseline disease factors, time to best response and duration of treatment after best response were not associated with PD. ICI was restarted in 8 of 14 pts (57%) with PD, with response rate to retreatment of 75% (4 CR, 2 PR, 1 SD, 1 PD – pt with leptomeningeal disease). Median time to best response at retreatment was 3 months (range 2 to 7), with all responses ongoing after a median of 10 months back on treatment. 3 pts had an isolated site of PD successfully treated with radiation therapy and remain in remission off ICI. Conclusions: ICI responses in mMCC do not appear as durable off treatment as in other cancers, including in patients who achieve a CR. Ongoing treatment should be considered, though initial data on response to retreatment is promising.[Table: see text]

Context.— Urothelial proliferation of unknown malignant potential (UPUMP) is a 2016 World Health Organization classifier that encompasses prior categories of flat and papillary urothelial hyperplasia. In addition, UPUMP occurs in settings of both de novo and prior bladder neoplasia. Objective.— To identify UPUMP features associated with subsequent neoplastic development. Design.— Sixty-eight patients were identified from the archives, including 26 patients with de novo and 42 patients with prior bladder neoplasia. Patient slides and clinical course were reviewed. Results.— Patients with de novo UPUMP were detected through clinical findings (26/26; 100%), whereas surveillance cystoscopy primarily detected UPUMP in patients with prior neoplasia (29/42; 69%). Histopathologic criteria evaluated included urothelial hyperplasia, urothelial cytology, vascular ingrowth, denudation, inflammation, edema, and fibrosis. Mean clinical follow-up was 68.9 months in patients with de novo neoplasia and 69.5 months in patients with prior neoplasia. Subsequent neoplasia developed in 4 of 26 (15.4%) of patients with de novo UPUMP and was associated with cystoscopic papillary appearance (P = .02) or microscopic thin papillary ingrowths or papillations (P = .02; median time to progression, 4.1 months). Of 42 patients with prior neoplasia, 17 (40.5%) had subsequent neoplasia, significantly associated with an absence of prominent lamina propria edema (P &lt; .001; median time to progression, 11.0 months). A higher rate of progression to high-grade disease was present in patients with a prior neoplasia versus those with de novo disease (58.9% versus 25%). Conclusions.— Urothelial proliferation of unknown malignant potential shows subsequent risk of neoplastic development of 17% in patients with de novo disease and 40% in patients with prior neoplasia. The greatest risk of progression is associated with early papillary formation.

PurposeTo identify the initiation or discontinuation of complementary therapy (CT) and determine the impact of sociodemographic and clinical factors on CT use among cancer patients.Patients and MethodsEligible patients were age 20 or older; newly diagnosed with stomach, liver, or colorectal cancer; and started their initial treatment at the National Cancer Center, Korea, between April 1, 2001, and April 30, 2003. In total, 541 cancer patients were surveyed in face-to-face interviews at baseline, and telephone follow-up interviews were performed every 3 months for 3 years.ResultsA total of 281 patients commenced CT after diagnosis; 164 patients stopped using CT during the follow-up period. The overall cumulative probability of starting CT at 1, 2, and 3 years was 50%, 54%, and 55%, respectively. In a Cox multivariate analysis, stomach and liver cancer were associated with an increased probability of initiating CT compared with colorectal cancer. Patients who were classified as stage I, II, or III at diagnosis were associated with a decreased probability of discontinuing CT compared with stage IV.ConclusionMost cancer patients started to use CT during the initial treatment period. Thus, physicians should communicate with cancer patients about CT at this phase. In particular, more attention should be paid to women and individuals with higher household incomes because these groups are more likely to start CT.
