RICTOR amplification is associated with Rictor membrane staining and does not correlate with PD-L1 expression in lung squamous cell carcinoma. (PubMed, Pathol Oncol Res)

In conclusion, the correlation between RICTOR amplification and Rictor membrane staining suggests that the latter can potentially be used as a surrogate marker to identify lung SCC cases with RICTOR amplification. Since a significant proportion of PD-L1 negative SCC cases harbor RICTOR amplification, analyzing PD-L1 negative tumors by RICTOR FISH or Rictor IHC can help select patients who may benefit from mTORC2 inhibitor therapy.

Primary pulmonary histiocytic sarcoma with high PD-L1 expression benefited from immunotherapy: A case report and bioinformatic analysis. (PubMed, Clin Respir J)

Following that, we found that the genetic alteration of PD-L1 was associated with poor prognosis in sarcoma patients in terms of overall survival (OS) (p = 1.51 × 10-4 ), progress-free survival (PFS) (p = 4.90 × 10-2 ) and disease-specific survival (DSS) (p = 4.90 × 10-2 ). To our knowledge, this may be the first reported case with high PD-L1 expression in primary pulmonary histiocytic sarcoma who may benefit from immunotherapy such as nivolumab and pembrolizumab significantly and safely.

Donor T cell STAT3 deficiency enables tissue PD-L1-dependent prevention of graft-versus-host disease while preserving graft-versus-leukemia activity. (PubMed, J Clin Invest)

In lymphoid tissues, the lack of host-tissue PD-L1 interaction with PD-1 reduced the inhibition of the GSH/Myc pathway despite reduced GSH production caused by STAT3 deficiency and allowed donor T cell functions that mediate GVL activity. Therefore, STAT3 deficiency in donor T cells augments PD-1 signaling-mediated inhibition of GSH/Myc pathways and augments dysfunction of T cells in GVHD target tissues while sparing T cells in lymphoid tissues, leading to prevention of GVHD while preserving GVL effects.

Then, TPP-LND is wrapped with liposomes to form TPP-LND@Lip nanoparticles.

As expected, these well-designed economical TPP-LND@Lip nanoparticles are more effective than conventional anti-PD-L1 antibodies to some extent.

Tumor Microenvironment and Its Clinicopathologic and Prognostic Association in Cutaneous and Noncutaneous Angiosarcomas. (PubMed, Am J Clin Pathol)

Our HTG analyses confirmed a high degree of tumor and microenvironment heterogeneity. Cutaneous ASs, ASs without MYC amplification, and ASs located in the head and neck area seem to be the most immunogenic subtypes in our series.

PD-L1 gene amplification and focality: relationship with protein expression. (PubMed, J Immunother Cancer)

In conclusion, PD-L1 expression measured by IHC is influenced by PD-L1 amplification level and focality. Further correlation between amplification, focality, protein expression and therapeutic outcome for PD-L1 and other targetable genes warrants exploration.

Diagnostic Accuracy of Slow-Capillary Endobronchial Ultrasound Needle Aspiration in Determining PD-L1 Expression in Non-Small Cell Lung Cancer. (PubMed, Adv Respir Med)

These retrospective study shows that slow-pull capillary aspiration carries an excellent diagnostic accuracy, almost equal to that one reported in literature, supporting its use in EBUS-TBNA for PD-L1 testing in NSCLC.

Clinical and molecular features of ATM and BRCA2 mutations in metastatic prostate cancer. (ASCO-GU 2023)

ATM or BRCA2 mutations also predicted worse response to the AR-targeted abiraterone/enzalutamide therapies (HR 0.4, 0.3; CI 0.244-1.003, 0.172 – 0.6; P = 0.047, p < 0.001). We found that somatic ATM and BRCA2 mutations associated with differential OS outcomes, which may help tailor treatment decisions. At the molecular level, ATM- and BRCA2-mutated tumors exhibited differences in the landscape of co-occurring genomic and transcriptional features. These features unique to ATM or BRCA2 mutations can inform rationale for divergent treatment strategies and should be investigated.

Prevalence of Predictive Biomarkers Detected by Comprehensive Genomic Profiling in Pineal Parenchymal Tumors (USCAP 2023)

Clinically advanced PPTs appear to be genomically stable neoplasms with low GA per tumor, extremely limited targeted therapy options with the exception of the MTOR pathway and limited immunotherapy options given the absence of MSI-high status and low TMB.
