Abstract BACKGROUND The development of next generation sequencing (NGS) based comprehensive genomic profiling (CGP) has enabled identification of druggable somatic mutations in brain tumours. This cohort reviewed the efficacy of CGP-guided precision treatment in a tertiary neuro-oncology centre. METHODOLOGY From May 2017 to May 2020, CGP were arranged for 43 patients. All patients had exhausted conventional treatments or received CGP for clinical trial screening. Targeted deep NGS was used to assess the mutational status, single nucleotide variant, small insertions and deletions and copy number variant of 440 cancer-related genes. RESULTS The diagnoses of the 43 patients were GBM (n=23), high grade glioma (n=11), brain metastases (n=4), chordoma (n=3), atypical choroid plexus papilloma (n=1) and meningioma (n=1). In most of the patients (42/43, 97.7%), CGP identified at least one druggable targets with a median of 3. Based on the CGP, 27 patients received precision treatment (62.7%). Among these, 14 were GBM and 6 were other high grade glioma. Treatment given included PARP inhibitors, immunotherapy, multi-kinase inhibitor, selective CDK4/6 inhibitor and mTOR inhibitor. Clinical benefit was achieved in 20 patients out of 27 (74%), including 2 complete response (7.4%), 9 partial response (33.3%) and 9 stable disease (33.3%). The median progression free survival (PFS) were 183 days [95% confident intervals (CI): 81–302 days]. For GBM/high grade glioma patients, median PFS was 125 days [95% CI: 52–215] and six-month PFS was 32.7%. Treatment toxicity was mild except two patients developed grade 3 complications and one grade 5 complication (fatal neutropenic fever). For the 16 patients who did not receive precision treatment, one had no druggable target identified, nine were still stable on standard therapies, 6 were too weak when CGP was available. CONCLUSION CGP guided precision treatment for selected, advanced neuro-oncological patients yielded modest clinical efficacy and satisfactory safety profile in real world setting.

Abstract Background Recent large-scale genomic studies have revealed a spectrum of genetic variants associated with specific subtypes of central nervous system (CNS) tumors. The aim of this study was to determine the clinical utility of comprehensive genomic profiling of pediatric, adolescent and young adult (AYA) CNS tumors in a prospective setting, including detection of DNA sequence variants, gene fusions, copy number alterations (CNAs), and loss of heterozygosity. Methods OncoKids, a comprehensive DNA- and RNA-based next-generation sequencing (NGS) panel, in conjunction with chromosomal microarray analysis (CMA) was employed to detect diagnostic, prognostic, and therapeutic markers. NGS was performed on 222 specimens from 212 patients. Clinical CMA data were analyzed in parallel for 66% (146/222) of cases. Results NGS demonstrated clinically significant alterations in 66% (147/222) of cases. Diagnostic markers were identified in 62% (138/222) of cases. Prognostic information and targetable genomic alterations were identified in 22% (49/222) and 18% (41/222) of cases, respectively. Diagnostic or prognostic CNAs were revealed by CMA in 69% (101/146) of cases. Importantly, clinically significant CNAs were detected in 57% (34/60) of cases with noncontributory NGS results. Germline cancer predisposition testing was indicated for 27% (57/212) of patients. Follow-up germline testing was performed for 20 patients which confirmed a germline pathogenic/likely pathogenic variant in 9 cases: TP53 (2), NF1 (2), SMARCB1 (1), NF2 (1), MSH6 (1), PMS2 (1), and a patient with 47,XXY Klinefelter syndrome. Conclusions Our results demonstrate the significant clinical utility of integrating genomic profiling into routine clinical testing for pediatric and AYA patients with CNS tumors.

832 Background: From June, 2019, two comprehensive genomic profiling (CGP) assays, "FoundationOne CDx" and “OncoGuide NCC Oncopanel”, were reimbursed by the national insurance system in Japan for patients who were refractory to standard chemotherapy. However, their clinical utility for chemotherapy-naïve cancer patients is unknown. Methods: We conducted a single institutional prospective observational study to evaluate the clinical utility of FoundationOne CDx assay (Cambridge, MA, USA) for the patients with chemotherapy-naïve advanced gastrointestinal malignancies. Patients with adequate H.E. sample were registered in this study. Primary outcome was the detection rate of at least one actionable/druggable cancer genomic alterations. The evidence levels were classified according to clinical practice guidance for next-generation sequencing in cancer diagnosis and treatment (Edition 1.0) (Sunami K. Cancer Sci. 2018). Results: From October 2018 to June 2019, a total of 238 patients were screened and the following 158 patients were registered: colorectal cancer (n = 60), gastric cancer (n = 19), esophageal cancer (n = 23), pancreatic cancer (n = 30), biliary tract cancer (n = 11), rare gastrointestinal malignancies (n = 15). The CGP data were obtained for 113 patients . Median turn-around time was 14 days (range 10-247 days). Actionable/druggable cancer genomic alterations were observed in 113 patients (100%)/ 65 patients (57.5%), respectively. Clinically relevant biomarkers and genomic alterations were identified in 22 patients (19.5%); BRCA2 (n = 4), ERBB2 (n = 4) , BRAF (n = 3) , EGFR (n = 3), FGFR2 (n = 2), MET (n = 2), NTRK (n = 2) , MSI-H (n = 2 ), TMB-high (n = 2), ALK (n = 1) , KIT (n = 1) and ROS1 (n = 1). Of note, novel biomarkers such as ROS1- GOPC fusion and PALB2 rearrangement were obtained in the patients with esophageal squamous cell carcinoma. Conclusions: This is the first study to evaluate the clinical utility of CGP in patient with chemotherapy-naïve advanced gastrointestinal malignancies. Our result indicated that CGP might provide a chance of potentially effective drugs as a novel approach in precision cancer medicine. Clinical trial information: UMIN000034830.

Abstract Objective: Photodynamic therapy (PDT) using Talaporfin Sodium (TS) is a novel therapeutic strategy to improve local tumor control in high-grade glioma. TS is a photosensitizer that accumulates in tumor cells and produces highly toxic free radicals by intraoperative irradiation of laser with a 664nm wavelength. However, little is known about the treatment outcomes of PDT in recurrent high-grade gliomas (rHGG). In this study, we investigated the treatment outcome of PDT in rHGG and evaluated the correlation between intratumoral TS accumulation and outcomes. Methods: We included 21 patients with rHGG and 22 tumors, who were treated by PDT between June 2016 and March 2021. TS was transvenously administered 22–26 hours before PDT. Intratumoral TS concentrations were measured by liquid chromatography using frozen tissue. Results: The rHGGs included 10 glioblastoma, IDH1/2-wildtype (GBM, IDH1/2-WT: 45.5%), 3 GBM, IDH1/2-mutant (GBM, IDH1/2-Mut: 13.6%), 7 anaplastic oligodendroglioma, IDH1/2-Mut/codel (AO, IDH1/2-Mut/codel: 31.8%), 1 anaplastic astrocytoma, IDH1/2-WT (AA, IDH1/2-WT: 4.5%), 1 high-grade astrocytoma, IDH1/2-WT (4.5%). The median local progression free survival (PFS) time after PDT was 3.6 months and the median survival time from PDT was 19.4 months. The intratumoral TS concentrations of 7 tumors (TS(-): 31.8%) were below the limit of quantification, and the intratumoral TS concentrations of the remaining 15 tumors (TS(+)) were 43.5 ng/mg-protein (14.7–132 ng/mg-protein). The intratumoral TS concentrations were not significantly associated with IDH1/2 mutation status, cellularity, tumor grade, and pattern of enhancement. The median PFS from PDT tended to be longer in TS(+) than in TS(-) (TS(+): 6.3 vs TS(-): 1.4 months, p = 0.054). Conclusions: We found that the intratumoral TS concentrations were heterogeneous and 31.8% were below the limit of quantification. TS(+) tended to have better local tumor control than TS(-), suggesting the intratumoral TS accumulation have an impact of treatment outcomes of PDT.

Comprehensive genomic profiling (CGP) for patients with advanced solid tumors is on the trajectory of becoming standard of care through incorporation into clinical practice, professional society guidelines, availability of an FDA-approved assay, and a national coverage determination from Medicare. For hematologic malignancies, the clinical utility of CGP can be diagnostic, prognostic, or predictive depending on the type of malignancy. Molecular testing has been standard of care for many years for hematologic malignancies, and payer coverage of the CGP approach must now be considered to keep pace with advances in the field of hematology-oncology. Based on American Medical Association CPT coding definitions, molecular testing for hematologic malignancies is categorized as testing for individual genes and gene panels of 5–50 genes or >50 genes. Our review of payer coverage policies from the Policy Reporter database in October 2018 demonstrated that payer coverage for >50 genes in hematologic malignancies is limited. As an example of coverage limitations, a recently updated Medicare Local Coverage Determination limits coverage to 50 genes or less. Coverage decisions such as these are being made during a time of increasing demand for an expanded approach. Data from the Foundation Medicine, Inc. database shows that as of April 2018, over 3,600 patients with AML, MDS, and MPN have undergone clinical testing with FoundationOne Heme, a CGP assay for hematologic malignancies. In an analysis of over 1,300 AML cases tested with FoundationOne Heme, 62% had an alteration that is included in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines), and 91% had a clinically relevant alteration identified that could inform diagnosis, prognosis, or treatment selection. In an analysis of over 1,300 MDS cases tested, 70% had at least one clinically relevant alteration identified. In an analysis of over 200 MPN cases tested, 48% were triple negative for CALR, JAK2, and MPL, and of those triple negative cases, 55% had another clinically relevant alteration. These data demonstrate that FoundationOne Heme is a clinically important assay for patients with hematologic malignancies including AML, MDS, and MPN, and stakeholders within the system must now come together to further refine the clinical utility, improve payer coverage, and ensure patient access to this impactful testing as the field advances.
