This review article outlines the current development of emerging treatment strategies for primary central nervous system lymphoma, a rare brain tumor with, thus far, limited therapeutic options. Small molecule targeted tyrosine kinase inhibitors, immunomodulatory agents, and immune checkpoint inhibitors will be discussed. The mechanisms of action, results of completed clinical studies, ongoing clinical trials, and future perspectives are summarized. Among the most promising clinical developments in the field of CNS lymphomas is ibrutinib, an inhibitor of Bruton’s tyrosine kinase, which relays activation of nuclear factor kappa B upon integration of constitutive B cell receptor and Toll-like receptor signals. Down-stream of nuclear factor kappa B, the thalidomide analogs lenalidomide and pomalidomide exert immunomodulatory functions and are currently explored against CNS lymphomas. Finally, immune checkpoint inhibitors, such as drugs targeting the PD-1 pathway, may become novel therapeutic options to unleash anti-tumor immunity in patients with primary CNS lymphoma.

Tumor Mutational Burden

Abstract Background Primary central nervous system lymphoma (PCNSL) is rare and there is limited genomic and immunological information available. Incidental clinical and radiographic responses have been reported in PCNSL patients treated with immune checkpoint inhibitors. Materials and Methods To genetically characterize and ascertain if the majority of PCNSL patients may potentially benefit from immune checkpoint inhibitors, we profiled 48 subjects with PCNSL from 2013 to 2018 with (1) next-generation sequencing to detect mutations, gene amplifications, and microsatellite instability (MSI); (2) RNA sequencing to detect gene fusions; and (3) immunohistochemistry to ascertain PD-1 and PD-L1 expression. Tumor mutational burden (TMB) was calculated using somatic nonsynonymous missense mutations. Results High PD-L1 expression (>5% staining) was seen in 18 patients (37.5%), and intermediate expression (1–5% staining) was noted in 14 patients (29.2%). Sixteen patients (33.3%) lacked PD-L1 expression. PD-1 expression (>1 cell/high-power field) was seen in 12/14 tumors (85.7%), uncorrelated with PD-L1 expression. TMB of greater than or equal to 5 mutations per megabase (mt/Mb) occurred in 41/42 tumors, with 19% (n = 8) exhibiting high TMB (≥17 mt/Mb), 71.4% (n = 30) exhibiting intermediate TMB (7–16 mt/Mb), and 9.5% (n = 4) exhibiting low TMB (≤6 mt/Mb). No samples had MSI. Twenty-six genes showed mutations, most frequently in MYD88 (34/42, 81%), CD79B (23/42, 55%), and PIM1 (23/42, 55%). Among 7 cases tested with RNA sequencing, an ETV6-IGH fusion was found. Overall, 18/48 samples expressed high PD-L1 and 38/42 samples expressed intermediate to high TMB. Conclusions Based on TMB biomarker expression, over 90% of PCNSL patients may benefit from the use of immune checkpoint inhibitors.

Abstract BackgroundThe survival benefit and safety of transarterial chemoembolization (TACE) for advanced Hepatocellular Carcinoma (HCC) patients treated with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) is unclear. We aimed to investigate the efficacy and safety of TACE combined with TKIs and ICIs the treatment of advanced HCC. MethodsIn this study, the conditions of 147 patients with advanced HCC who underwent TKIs plus ICIs treatment between July 2017 and April 2020 were evaluated. We divided these patients into the TACE group and non-TACE group based on whether they were treated with TACE during TKIs plus ICIs treatment, and compared their survival outcomes, especially overall survival (OS), and whether they were exposed to unexpected toxicities. ResultsIn this study, a total of 98 patients who underwent TACE during TKIs plus ICIs treatment were included in the TACE group, while the other 49 patients were included in the non-TACE group. According to the Modified Response Evaluation Criteria in Solid Tumors (mRECIST), the objective response rate (ORR) of the TACE group was higher than that of the non-TACE group (ORR 74.5% vs. 40.8%, p ＜0.001). The OS of the TACE group was significantly longer than the non-TACE group (OS 19.3 months vs. 10.8 months, p = 0.010). The incidence of grade 3-4 toxicities in the TACE group was similar to that in the non-TACE group (33.7% vs. 28.6%, p = 0.532). ConclusionsThe TACE treatment combined with TKIs plus ICIs resulted in longer OS compared to the treatment of systemic TKIs plus ICIs without TACE during the process of advanced HCC.

274 Background: MiT family translocation renal cell carcinomas (TRCC) represent a rare and aggressive subgroup of RCC harboring high expression of c-MET. While response rates of VEGF receptor-tyrosine kinase inhibitor and immune checkpoint inhibitors are limited, efficacy of cabozantinib (a TKI that inhibits VEGFR, MET, and AXL) in this subgroup is unclear. Methods: We performed a multicentre, retrospective, international cohort study of patients with TRCC treated with cabozantinib regardless the line of treatment at 7 centers (3 in France and 4 in the US). The main objectives were to estimate response rate according to RECIST criteria, and to analyze progression-free survival (PFS) and overall survival (OS). Results: Among 31 metastatic patients treated in the participating centers, 24 were evaluable for response and were included in this study (21 with TFE3 and 3 with TFEB translocations). Median age at diagnosis was 43.5 years (range, 22–70). Most frequent metastatic sites at diagnosis were lungs (62.5%), retroperitoneal lymph nodes (45.8%) and bone (37.5%). Patient’s IMDC risk group at diagnosis was favourable (20,8%), intermediate (62,5%) and poor (16,7%). Seven (29%) patients received cabozantinib at first line, 9 (37.5%) at second line and 8 (33%) at third line and beyond. The proportion of patients who achieved an objective response was 16.6%, including 1 complete response and 3 partial responses. For 11 (45.8%) patients, stable disease was the best response. With a median follow-up of 14 months (IQR 5-23), median PFS was 8.4 months (range, 1-34+) and median OS was 17 months (range, 2-43). No PFS difference was detected overall or in any subgroup except in patients with bone metastasis which harbored a median PFS of 3.6 months as compared to 9.1 months for those without (p=0.03). Conclusions: This real-world study provides evidence supporting activity of cabozantinib in TRCC, with more durable responses to therapy than those observed with of VEGF receptor-tyrosine kinase inhibitor and immune checkpoint inhibitors. International collaborations and prospective studies are necessary to identifies efficacious therapies for this rare disease that lacks evidence-based treatment options.

PurposeTo explore the safety and efficacy of transarterial chemoembolization (TACE) in combination with immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) for the treatment of unresectable hepatocellular carcinoma (uHCC).Materials and MethodsFrom August 2019 to July 2020, patients who received TACE combined with ICIs and TKIs were retrospectively analyzed. Treatment-related adverse events (AEs) were recorded. The Kaplan–Meier method was used to estimate time to progression (TTP) and progression-free survival (PFS).ResultsIn total, 31 patients with uHCC were included. Eleven patients were classified as BCLC-C. Nineteen patients had multiple lesions, and the cumulative targeted lesions were 69 mm (range, 21-170 mm) according to mRECIST. Twenty-nine (93%) patients experienced at least one AE during the treatment. Four (12.9%) patients developed AEs of higher grade (grade≥3). The objective response rate (ORR) and disease control rate (DCR) were 64.5% and 77.4%, respectively. The median time to response was 7 weeks (range, 4-30 w), and the duration of response was 17.5 weeks (range, 2-46 w). From the first ICIs, TTP and PFS were 6.5 months (95% CI, 3.5-11) and 8.5 months (95% CI, 3.5-NE), respectively.ConclusionsTACE combined with ICIs and TKIs shows an acceptable safety profile and considerable efficacy in patients with HCC.
