PD-L1 negative + TMB-L

Most DEGs were involved in the neuroactive ligand-receptor interactions, calcium, cAMP and cell adhesion signalling pathways. Immune, chemokine and JAK-STAT signalling pathways were positively enriched in PD-L1-high tumours.Conclusions This integrative analysis of clinical, genetic, transcriptomic and immunohistochemical data revealed differences in mutational signatures and gene expression patterns between PD-L1-high and -low TNBC tumours.

Similar results for biomarkers were observed in NADIM and NADIM II ChIO cohorts analyzed separately, and were not predictive of patients’ outcomes when analyzed in posttreatment samples or in chemotherapy treated patients. Conclusions : Baseline TCR metrics, particularly convergence, evenness, and TOP1% CS, demonstrate robust predictive value for CPR and survival in locally-advanced NSCLC patients undergoing perioperative nivolumab plus chemotherapy, warranting further investigation in larger cohorts.

In this phase 2 multicenter study, we evaluated the efficacy and safety of lifileucel (LN-145), an autologous tumor-infiltrating lymphocyte cell therapy, in patients with metastatic non-small cell lung cancer (mNSCLC) who had received prior immunotherapy and progressed on their most recent therapy. Two patients died of treatment-emergent adverse events: cardiac failure and multiple organ failure. Lifileucel is a potential treatment option for patients with mNSCLC refractory to prior therapy.

High TMB has a prognostic role in resectable lung ADC. The high TMB group had a poor outcome with AC, suggesting that this group may be better served with immune checkpoint therapy.

Regardless of the presence of PDL1 expression, high TMB, or MSI, adding immune checkpoint inhibitors to the treatment regimen for metastatic head and neck malignancies and lung tumours that lack driver mutations is obviously advantageous. On the other hand, immunotherapy had no effect on gastrointestinal, gynaecological, or urothelial tumours. To validate these findings, more research with several centres and a sizable sample size is necessary.

To our knowledge this is the largest real-world dataset indicating that enrichment of both the STING gene, and gene signatures associated with the STING pathway represent valuable transcriptomic biomarkers to stratify pts with PDL1-negative and TMB-Low NSCLC who benefit more from IO therapies. Conversely, novel IO combination strategies need to be employed in STING-low tumors to enhance outcomes. >

these findings suggest some clinicopathological and molecular features that, added to PD-L1 expression, could help in the selection of the most appropriate first-line IO-based treatment for advanced NSCLC patients.

Cell-free CNV may be a useful peripheral blood biomarker for predicting the response to ICIs in patients with NSCLC.

The IIP, as evaluated by Lunit SCOPE IO, may represent a practical, clinically-actionable biomarker predictive of favorable ICI treatment outcomes across diverse cancer patient populations, including those with PD-L1 negative, MSS/TMB-low tumors, in whom predictive biomarkers are urgently needed.

High pretreatment levels of plasma immunosuppressive cytokines, chemokines, and immune checkpoint molecules were associated with rapid progression. Although this study did not meet its primary endpoint, immunostaining, genomic, and proteomic studies indicated a high degree of tumor immunosuppression in this mTNBC cohort.

This case showed relatively good prognosis after using anti-angiogenic agent, anlotinib, and immunotherapeutic drug, sintilimab, suggesting a new direction in treating recurrent and inoperable ATC patients, and also providing a new way for cancer patients with PD-L1 negative/TMB-low.
