Abstract 2211: The prognostic role of tertiary lymphoid structure (TLS) in locally advanced esophageal squamous cell carcinoma (ESCC)

Cancer Research, 2023
Abstract Introduction: The presence of TLS in tumors is associated with improved efficacy of immunotherapy in various types of cancer. The significance of TLS in patients with ESCC has been sporadically reported. The study aimed to investigate the prognostic significance of TLS in patients with locally advanced ESCC receiving neoadjuvant

Abstract 5627: Functional tertiary lymphoid structure (TLS) and outcome in HER2-positive (HER2+) breast cancer in NCCTG N9831 (Alliance)

Cancer Research, 2022
Abstract Background: Previous studies showed conflicting results regarding association between stromal tumor infiltrating lymphocytes (sTIL) and outcome in HER2+ breast cancer. While sTIL were not associated with outcome in patients (pts) treated with trastuzumab in N9831, immune functions genes are linked to outcome in these pts. TLS is

Abstract 1705: Spatial interrogation of tertiary lymphoid structures (TLS) in colorectal carcinoma (CRC) tumor microenvironment (TME) using the MultiOmyx࣪ assay

Cancer Research, 2022
Abstract Immune checkpoint blockade (ICB) therapy has revolutionized the landscape of cancer therapy in multiple tumor types since Ipilimumab, the first ICB agent, was approved for the treatment of metastatic melanoma is 2011. Current predictive biomarkers for therapy response include PD-L1 expression, tumor mutational burden (TMB) and ...

Abstract 74: Engineering tertiary lymphoid structures for glioblastoma: A novel gene combination promotes therapeutic TLS formation in an immune-competent mouse model of GBM

Cancer Research, 2021
Abstract The absence of conventional lymphatic access to the brain parenchyma restricts the capacity of the peripheral immune system to recognize and elicit durable responses against glioma antigens. In some peripheral solid tumor types and autoimmune diseases such as multiple sclerosis, the spontaneous development of tertiary lymphoid ...

Identifying gut microbial signatures associated with B cells and tertiary lymphoid structures (TLS) in the tumor microenvironment (TME) in response to immune checkpoint blockade (ICB).

Journal of Clinical Oncology, 2022
2511 Background: While ICB has significantly improved clinical outcomes across several cancer types, only 15-20% of patients develop a durable response. Thus, novel and targetable biomarkers are needed. There is increased appreciation of the role of the gut microbiome, and TLS and B-cells in the TME in response to ICB.

Significance of intratumoral tertiary lymphoid structure (TLS) as predictictive factors of nivolumab therapy after conversion surgery for unresectable gastric cancer: A retrospective study.

Journal of Clinical Oncology, 2020
412 Background: Conversion surgery for unresectable advanced gastric cancer has been increasing with the development of chemotherapy. Adjuvant chemotherapy regimens after conversion surgery have not been standardized. The main mechanism of nivolumab is augmentation of antitumor immune response of tumor infiltrating cytotoxic T cells (CTL) to cancer ...

Artificial intelligence (AI) –powered H&E whole-slide image (WSI) analysis of tertiary lymphoid structure (TLS) correlates with immune phenotype and related molecular signatures in non–small-cell lung cancer.

Journal of Clinical Oncology, 2023
e20520 Background: Recent data suggested immune infiltrates in TLS around tumor bed may be a favorable predictive factor for immunotherapy in various cancers. TLS have been suggested to be correlated with inflamed immune phenotype and relevant inflammatory gene signatures of adaptive immunity.

Abstract 4909: An RNA-based model for tertiary lymphoid structure (TLS) prediction and classification in pancreatic adenocarcinoma (PDAC)

Cancer Research
Abstract Although TLS status possesses prognostic significance in PDAC and can potentially affect chemotherapy outcomes, there is currently a notable lack of RNA sequencing (RNA-seq) models that specialize in TLS identification and classification in PDAC. Here, we developed a model for predicting TLS status (high or low) based on RNA-seq

Abstract 2219: CXCL13 secretion and immobilization show distinct geographies within secondary and tertiary lymphoid structures (TLS).

Cancer Research
Abstract The purpose of this study is to investigate the formation and maintenance of germinal centers in TLS by defining mechanisms and spatial patterns of CXCL13 chemokine gradients in tumor tissue. In secondary lymphoid tissue, it is recognized that CXCL13 is immobilized by follicular dendritic cells (FDCs), but the mechanisms of ...

Abstract 7761: Tertiary lymphoid structure (TLS) representative cells elicit response to anti-PD-1+ therapy in a cold tumor

Cancer Research
Abstract The composition and activation phenotype of immune cells within the tumor microenvironment (TME) can significantly influence therapeutic response to PD-1 based immunotherapy. Using the Farcast TruTumor histoculture platform, we investigated potential factors contributing to the unexpected anti-PD-1 responsiveness in an immune
