(要約) Thymic carcinoma is a rare and aggressive malignancy with limited treatment options, resulting in a poor prognosis. Lenvatinib, a small-molecule inhibitor targeting multiple receptor tyrosine kinases, including fibroblast growth factor receptors (FGFRs), has been approved for thymic carcinoma that progresses following platinum-based chemotherapy. However, the identification of predictive biomarkers for its efficacy remains an unmet medical need. We herein present a case of 67-year-old man with advanced thymic carcinoma who was treated with carboplatin plus paclitaxel as first-line therapy. Lenvatinib, administered as second-line therapy, achieved a durable disease control that was maintained for over 20 months-exceeding the previously reported median progression-free survival. Comprehensive genomic profiling (CGP) using the FoundationOne® CDx assay identified an oncogenic FGFR3 S249C mutation. The case, together with supporting literature, suggests the potential role of FGFR3 mutations as therapeutic targets in thymic carcinoma. Furthermore, the presence of oncogenic mutations in lenvatinib-targeted genes may serve as predictive biomarkers for durable disease control. Given the limited availability of methods to detect oncogenic mutations, including FGFR3, in patients with thymic carcinoma, early implementation of CGP testing-even in the frontline setting-may be warranted in the future.

(要約) The recent studies with comprehensive genomic analyses demonstrated that a certain proportion of patients with pulmonary large-cell neuroendocrine carcinoma (LCNEC) harbors some driver gene alterations. We herein present a case of 79-year-old man with Kirsten rat sarcoma virus oncogene homologue G12C-mutated pulmonary LCNEC who were treated with chemo-immunotherapy in the first-line setting. Sotorasib which was administered as second-line therapy showed a favorable therapeutic efficacy of partial response. Although sotorasib induced severe hepatobiliary disorder which forced us to terminate the treatment, the antitumor response was sustained for up to 5.6 months which was almost comparable to the therapeutic efficacy reported in pivotal clinical trials. Our case and related literature review suggest that the multiplex genetic mutation-detection assay should be considered for patients with LCNEC. Furthermore, it also suggests that biomarkers which enable us to distinguish patients who are likely to harbor driver gene alterations are required in near future.

(要約) Neurological immune-related adverse events can manifest as paraneoplastic neurological syndrome (PNS), especially in patients with small-cell lung cancer (SCLC). We herein report a 73-year-old man with SCLC treated with an immune checkpoint inhibitor (ICI) combined with chemotherapy. Although the chemo-immunotherapy induced a favorable response to SCLC, he later developed acute cerebellar ataxia. He was diagnosed with paraneoplastic cerebellar degeneration associated with anti-Sry-like high mobility group box 1 (SOX1) autoantibody. The antibody was also identified in serum collected at the diagnosis of SCLC and before ICI administration, which retrospectively suggested that the patient was at risk of ICI-induced PNS. J. Med.

(要約) Immune checkpoint inhibitors (ICIs) targeting programmed death ligand-1 (PD-L1) provide clinical benefits for various advanced malignancies. However, the predictive factors that determine sensitivity to ICIs have not been fully elucidated. We focused on tumor-derived CXCL10/11 as a pivotal factor that determines the response to PD-L1 blockade by regulating T cell accumulation and tumor angiogenesis. We previously reported that CXCL10/11 was upregulated by interferon (IFN)-γ in ICI-sensitive tumor cells but not in ICI-resistant cells, including mouse Lewis lung carcinoma (LLC). In the present study, gene silencing of tumor-derived CXCL10/11 induced resistance to PD-L1 blockade in AB1-HA mesothelioma cell-bearing mice. To identify the mechanisms underlying ICI resistance, we performed a microarray analysis to compare the IFN-γ-inducible genes between ICI-sensitive AB1-HA and ICI-resistant LLC in vitro. A pathway analysis based on microarray data indicated that hypoxia-inducible factor (HIF) 1A is the key signal that inhibits CXCL10/11 expression. We revealed that the HIF1A inhibitors echinomycin (EC) and YC-1 upregulated CXCL10/11 genes induced by IFN-γ in tumor cells in vitro. In addition, combination therapy with PD-L1 blockade and EC demonstrated synergistic antitumor effects in LLC-bearing mice. Combination therapy enhanced tumor infiltration of CD8 T cells and suppressed tumor angiogenesis. The present study suggests that HIF1A signaling in tumor cells dominates ICI resistance via the downregulation of tumor-derived CXCL10/11.

(要約) Granulocyte colony-stimulating factor (G-CSF) has the potential to attenuate the anti-tumor immune responses of T-cells by increasing immune suppressive neutrophils and myeloid-derived suppressor cells. However, the clinical impact of G-CSF on the efficacy of immunotherapy remains unknown. This multi-center retrospective analysis evaluated the impact of G-CSF in patients with extensive-stage small-cell lung cancer (ES-SCLC) treated with chemo-immunotherapy. We analyzed 65 patients with ES-SCLC who completed four cycles of induction chemo-immunotherapy and evaluated the effects of G-CSF on progression-free survival (PFS), overall survival (OS), and a durable response to immunotherapy (defined as PFS 12 months). Fifty patients (76.9%) received 1 dose of G-CSF. The PFS of the patients with G-CSF was poorer than that of the patients without G-CSF (median PFS 8.3 vs. 4.9 months, p = 0.009). The OS of the patients with G-CSF tended to be shorter, but not statistically significant, than that of the patients without G-CSF (median OS 24.3 vs. 16.4 months, p = 0.137). In the multivariate analysis, G-CSF administration was associated with poorer PFS (hazard ratio 2.78, 95% CI 1.36-5.69, p = 0.005) and was identified as a determinant of a durable response (odds ratio 0.18, 95% CI 0.04-0.80, p = 0.024). These results were consistent with other definitions of G-CSF administration (administration of 1 dose of pegfilgrastim, or either 5 doses of filgrastim or 1 dose of pegfilgrastim). G-CSF has the potential to attenuate the efficacy of immunotherapy; therefore, the indication for G-CSF during chemo-immunotherapy should be carefully considered for ES-SCLC.
