Abstract BACKGROUND: Of solid tumors, melanoma has the highest propensity for CNS spread with historic median survivals of 5–8 months following brain metastasis diagnosis. We evaluated the impact of systemic BRAF targeted and immune checkpoint inhibitor (ICI) therapies on survival outcomes in patients receiving stereotactic radiosurgery (SRS) for melanoma brain metastases (MBM) and assessed patient treatment burden associated with prolonged survival. METHODS: We retrospectively reviewed the demographics, disease characteristics, therapeutic regimens, overall survival, and first-year cumulative incidence of comorbid disease for patients with de novo MBM treated between 2013 and 2017 at a major melanoma referral center. RESULTS: Among 123 newly diagnosed MBM patients: 65% were male, 24% were 50 years old or less, 50% were BRAF mutated, 63% had multiple intracranial lesions at diagnosis. Locally, 73% received SRS as first-line treatment. Systemically, 73% received ICI, 46% received BRAF targeted therapy, and 12% received neither. With a median follow up of 11 months (mo), total cohort median OS was 13.2 mo. Median OS for first-line SRS combined with ICI and BRAF targeted therapy was 31.0 mo (47% 3-year OS), 17.5 mo (31% 3-year OS) with ICI monotherapy, and 6.1 mo (22% 3-yr OS) alone. SRS and BRAF targeted therapy were associated with improved OS. At one-year follow-up, comorbid conditions with the greatest cumulative incidence were fatigue, nausea, intracranial hemorrhage, deep vein thrombosis, major depressive disorder, and pneumonia. Patients averaged one inpatient visit every 4.5 mo (1 week average length of stay), and 2 advanced imaging studies (MR/CT/PET-CT) per month following MBM diagnosis. CONCLUSIONS: In one of the largest reported MBM series, survival has improved markedly for patients receiving first-line SRS combined with targeted and immunotherapies. Simultaneously, longer life expectancy comes with increasing incidences of comorbid conditions reflecting an evolving complexity of and need for coordination of care for patients with MBM.

e13577 Background: Of solid tumors, melanoma has the highest propensity for central nervous system spread with historic median survivals of 5-8 months following brain metastasis diagnosis. We evaluated the impact of systemic BRAF targeted and immune checkpoint inhibitor (ICI) therapies on survival outcomes in patients receiving stereotactic radiosurgery (SRS) for melanoma brain metastases (MBM) and assessed patient treatment burden associated with prolonged survival. Methods: We retrospectively reviewed the demographics, disease characteristics, therapeutic regimens, overall survival, and first-year cumulative incidence of comorbid disease for patients with de novo MBM treated between 2013 and 2017 at a major melanoma referral center. Results: Among 123 newly diagnosed MBM patients:65% were male, 24%were 50 years old or less, 50% were BRAF mutated, 63% had multiple intracranial lesions at diagnosis . Locally, 73% received SRS as first-line treatment.Systemically, 73% received ICI, 46% received BRAF targeted therapy, and 12% received neither. With median follow up of 11 months (mo), totalcohort median OS was 13.2 mo, 20.5 mo for BRAF mutated patients, 10.8 mo for BRAF wild-type patients. Median OS for first-line SRS was 31.0 mo (47% 3-year OS) when combined with both ICI and BRAF targeted therapy, 17.5 mo (31% 3-year OS) when combined with ICI monotherapy, and 6.1 mo (22% 3-yr OS) with neither systemic therapy. SRS and BRAF targeted therapy were associated with improved OS. BRAF status, ICI therapy, intratumoral hemorrhage were not significant prognosticators for OS.At one-year follow-up, comorbid conditions with the greatest cumulative incidence were fatigue, nausea, intracranial hemorrhage, deep vein thrombosis, major depressive disorder, and pneumonia. Patients averaged one inpatient visit every 4.5 mo (1 week average length of stay), and 2 advanced imaging studies (MR/CT/PET-CT) per month following MBM diagnosis.

BackgroundAvelumab, a PD-L1 immune checkpoint inhibitor (ICI), was recently approved as first-line (1L) maintenance therapy for locally advanced/unresectable or metastatic urothelial carcinoma (aUC) after disease control with platinum-based chemotherapy.1 Given the evolving treatment landscape, the study aim was to gain real-world insights into clinical decision-making among oncologists for patients with aUC.MethodsIn March 2021, a cross-sectional web-based survey was administered to a sample of US oncologists treating patients with aUC. Oncologists' demographics, practice characteristics, and treatment patterns were obtained; descriptive statistics were used.ResultsThe study included 151 medical oncologists, who reported that 54% and 31% of their patients, on average, would be classified as cisplatin or carboplatin eligible for their 1L treatment, respectively. Approximately 78% of oncologists (n=118) considered using ICI maintenance in ≥40% of their patients following disease control with platinum chemotherapy and were categorized as the “high-consideration” group, for further exploratory analysis; the rest (22%) were in the low-consideration group (See table 1). Approximately, 31% and 27% of oncologists in the high- and low-consideration groups reported administering ICI maintenance with a 2–3-week gap after chemotherapy, while 45% and 46% reported administering it with a 4–6-week gap after chemotherapy, respectively.ConclusionsSurveyed oncologists reported that 85% of patients with aUC in US may be eligible for platinum-based chemotherapy. Further, 78% of the surveyed oncologists would consider 1L ICI maintenance therapy after disease control with platinum-based chemotherapy for over 40% of their patients. Future studies are warranted to evaluate real-world treatment patterns, barriers, and utilization of ICI maintenance therapy as the new 1L standard of care.AcknowledgementsThe authors would like to acknowledge all physicians at who participated and completed the survey for the study.ReferencePowles T, et al.

e16194 Background: Hepatocholangiocarcinoma (HCC-CC) is a rare form of cancer with a poor prognosis. Of all primary liver cancers, the incidence of HCC-CC ranges from 0.4 to 14.2%. HCC-CC is a mixed carcinoma with findings of both hepatocellular carcinoma and cholangiocarcinoma. Immune checkpoint inhibitors are a potent first line treatment in hepatocellular carcinoma with multiple clinical trial showing effectiveness in cholangiocarcinoma. HCC-CC has limited proven treatment options as patients are generally excluded from clinical trials. In this study we reviewed outcomes of patients with HCC-CC who received immune checkpoint inhibitor in a single center. Methods: Records of patients who had a pathological confirmed HCC-CC by a subspecialized hepatic pathologist at the University of Kansas medical center were reviewed. We identified 6 patients with locally advanced unresectable or metastatic HCC-CC that received immune checkpoint inhibitor between February 2017 and January 2021. Baseline characteristics were obtained, as well as best response, line of therapy, and duration of response. Results: Of the six patients 4 (66%) received PD-1 inhibitor alone and 2 (34%) received combination therapy with CTLA-4 inhibitor for the treatment of HCC-CC. There were 3 (50%) females and 6 (100%) with prior hepatitis C infection. four (66%) patients had metastatic disease and 2 had locally unresectable advanced disease. Objective response rate was 83.3%. One patient achieved complete response and had a treatment holiday after receiving treatment for 2 years, and restarted immunotherapy upon relapse. Four patients had a partial response, of which two passed away after disease progression. One patient had stable disease on 2 different lines of immunotherapy then progressed. Of those who responded, one patient received immunotherapy, 3 (50%) received liver directed therapy and two received chemotherapy or Lenvatinib as first line treatment (Table). Conclusions: Immune checkpoint inhibitors demonstrate potential activity in patients with HCC-CC without unexpected side effect in this unmet need high-risk population. Larger studies are needed to confirm activity and efficacy in this setting.[Table: see text]

e14006 Background: Previous studies have shown that brain metastases of non-small cell lung cancer (NSCLC) with positive driver genes have poor prognosis. There is still lack of prospective studies on the efficacy and safety of targeted therapy combined with concurrent radiotherapy for brain metastases(BM). Methods: NSCLC patients, with ECOG score 0-2, having MRI confirmed brain or meningeal metastases were eligible. Patients must have driver gene mutation and received corresponding targeted therapy. The intracranial radiotherapy regimen was SRS or whole brain radiotherapy. The primary objective was iPFS (intracranial progression-free survival); Secondary objectives were: iORR (intracranial objective response rate), PFS (progression-free survival), OS (overall survival). MMSE (Mini Mental State Examination) and FACT-Br was carried out before/after weekly radiotherapy and during systematic treatment. Treatment-related toxicities were assessed according RTOG/EORTC criteria. Tumor responses were evaluated using RECIST V1.1 criteria. Survival analysis was performed using the Graphprism version 6.0 by Kaplan-Meier method and log-rank test. Results: 23 NSCLC with BM was included. Among them, 10 patients were newly diagnosed with NSCLC BM. 2 patients’ BM progressed after targeted therapy. 11 NSCLC patients were newly diagnosed with BM after targeted therapy. 91.3% of patients presented an EGFR mutation, including primarily EGFR 19-exon deletion, EGFR 21-L8585R. 11.5% presented with c-MET mutation. Median age was 58.34 yrs(44-71yrs). Patients were mostly treated with Erolotinib and Gefitinib. All patients were adenocarcinoma. At last follow-up, for patients newly diagnosed with NSCLC BM, 8 patients had achieved intracranial progression, and 7 patients had reached OS, of which 1 died before completing WBRT. The median iPFS was 9.3m(95%CI:0.571-4.055) and the median OS was 11.9m (95%CI:0.2752 -2.732). As for patients who progressed after targeted therapy, one patient’s OS was 4.4m, iPFS of the other patient was 3.9m. Among NSCLC patients who were newly diagnosed with BM after targeted therapy, 8 patients had achieved intracranial progression and 5 patients had reached OS. The median iPFS was 6.13m (95%CI:0.247-1.751) and the mOS was 13.8m (95%CI:0.3660-3.634). Common adverse effects include dry skin, fatigue, dizziness, headache, anorexia, and grade I myelosuppression and no serious adverse events (SAEs); MMSE and FACT-Br scores were no significant differences at baseline and follow-up. Conclusions: In stage IV brain metastatic NSCLC with driver gene mutation, targeted therapy combined with concurrent radiotherapy for BM is tolerable, and there is no significant impact on the quality of life and cognitive function after radiotherapy. The evaluation of efficacy requires further follow-up. Support:LC2019ZD009,81972853 and 81572279.

Thromboembolism Events

Aim: To evaluate the correlation between venous thromboembolism events (VTEs) and immune checkpoint inhibitor (ICI)-based regimens. Methods: This is a retrospective study of 403 patients with advanced cancer on ICI-based regimens. Results: We report 8% VTE incidence post-ICI initiation over a median of 11.1 months of follow-up. Compared with single-agent ICI, dual-ICI was significantly correlated with higher incidence of VTE (odds ratio [OR]: 4.196, 95% CI: 1.527–11.529, p = 0.005), but chemotherapy–immuno-oncology combination was not (OR: 1.374, 95% CI: 0.285–6.632, p = 0.693). Subsequent systemic therapy post-ICI was also independently associated with higher VTE incidence (OR: 2.599, 95% CI: 1.169–5.777, p = 0.019). Conclusion: Our findings suggest potential underreporting of VTE incidence in ICI clinical trials. As dual-ICI is becoming more prevalent in cancer management, clinicians should maintain vigilance regarding VTE in patients with advanced cancer on ICI-based regimens.

Advanced Urothelial Carcinoma

Aim: Standard first-line treatment of advanced urothelial cell carcinoma involves cisplatin-based chemotherapy, with carboplatin or immune checkpoint inhibitor therapy (ICI) reserved for cisplatin-ineligible individuals. Methods: Using a large de-identified electronic health record-derived database of patients with advanced urothelial cell carcinoma in the USA, we examined trends in utilization of first-line systemic therapies in cisplatin-eligible patients from 1 January 2015 to 31 March 2018. Results: Among 1181 cisplatin-eligible patients, the quarterly proportion who received first-line ICI increased from 1 to 42% (ptrend <0.001), while the proportion who received cisplatin-based chemotherapy decreased from 53 to 33% (ptrend = 0.018). Patients receiving ICI were older than those receiving cisplatin (median age: 75 vs 68). Conclusion: Our analysis suggests rising off-label ICI use in cisplatin-eligible individuals, potentially because of ICI’s favorable toxicity profile.

The Impact

ObjectiveWe sought to investigate the long-term outcomes of patients who develop immune checkpoint inhibitor (ICI)-induced inflammatory arthritis (IA), to define factors associated with IA persistence after ICI cessation, the need for immunosuppressants and the impact of these medications on underlying malignancies.MethodsWe conducted a prospective observational study of patients referred for IA associated with ICIs. Patients were recruited from June 2015 to December 2018. Information was obtained at the baseline visit, and follow-up visits occurred at varying intervals for up to 24 months from ICI cessation. Kaplan-Meier curves were developed to characterise IA persistence. Cox proportional hazards models were used to assess the influence of various factors on IA persistence. Logistic regression was used to evaluate the impact of IA treatment on tumour response.ResultsSixty patients were monitored with a median follow-up after ICI cessation of 9 months. A majority (53.3%) had active IA at their most recent follow-up. IA was less likely to improve in those with longer duration of ICI use, in those receiving combination ICI therapy, and in patients with multiple other immune-related adverse events. Tumour response did not appear to be impacted by immunosuppression. Although not statistically significant, persistent IA was correlated with a better tumour response (complete or partial response).ConclusionICI-induced IA can become a long-term disease necessitating management by rheumatology for immunomodulatory treatment. Importantly, the use of immunomodulatory treatment has not been shown to impact cancer outcomes in this study.
