Artificial neural network systems to predict the response to sintilimab in squamous-cell non-small-cell lung cancer based on data of ORIENT-3 study.

Background: Existing biomarkers and models for predicting response to programmed cell death protein 1 monoclonal antibody in advanced squamous-cell non-small cell lung cancer (sqNSCLC) did not have enough accuracy. We used data from the ORIENT-3 study to construct artificial neural network (ANN) systems to predict the response to sintilimab for sqNSCLC.

Methods: Four ANN systems based on bulk RNA data to predict disease control (DC), immune DC (iDC), objective response (OR) and immune OR (iOR) were constructed and tested for patients with sqNSCLC treated with sintilimab.

Proteomic profiling reveals the significance of lipid metabolism in small cell lung cancer recurrence and metastasis.

Methods: In this study, we conducted a comprehensive proteomic analysis of 90 primary tumors, 15 patient-matched lymph node metastatic tumors, and 15 brain metastatic tumors derived from a cohort of 105 SCLC patients.

Safety and efficacy of amulirafusp alfa (IMM0306), a fusion protein of CD20 monoclonal antibody with the CD47 binding domain of SIRPα, in patients with relapsed or refractory B-cell non-Hodgkin lymphoma: a phase 1/2 study.

Background: Amulirafusp alfa (IMM0306) is a fusion protein of CD47 binding domain of signal-regulatory protein alpha (SIRPα) with CD20 monoclonal antibody on both heavy chains. This study aimed to evaluate the safety and preliminary efficacy of amulirafusp alfa in relapsed or refractory (r/r) B-cell non-Hodgkin lymphoma (B-NHL).

Methods: We enrolled patients with CD20 + r/r B-NHL who had previously received at least two lines of therapy to receive a single-dose of amulirafusp alfa in the first 2 weeks, followed by a multiple-dose period, in which the patients received the same intravenous dose every week in 4-week cycles.

Plasma metabolomics profiling of EGFR-mutant NSCLC patients treated with third-generation EGFR-TKI.

Third-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the latest and a vital treatment option for non-small cell lung cancer (NSCLC) patients. Although EGFR-sensitive mutations are an indication for third-generation EGFR-TKI therapy, 30% of NSCLC patients lack response and all patients inevitably progress. There is a lack of biomarkers to predict the efficacy of EGFR-TKI therapy.

Spatial analyses revealed CXCL5 and SLC6A14 as the markers of microvascular invasion in intrahepatic cholangiocarcinoma.

DKK1+ tumor cells inhibited the infiltration of CCL19+ fibroblasts and plasma cells contributing to worse immunotherapy response in hepatocellular carcinoma.

Intra-tumor immune infiltration plays a pivotal role in the interaction with tumor cells in hepatocellular carcinoma (HCC). However, its phenotype and related spatial structure remained elusive. To address these limitations, we conducted a comprehensive study combining spatial data (38,191 spots from eight samples) and single-cell data (56,022 cells from 20 samples).

The co-location of MARCO+ tumor-associated macrophages and CTSE+ tumor cells determined the poor prognosis in intrahepatic cholangiocarcinoma.

Intra-tumor immune infiltration is a crucial element interacting with tumor cells in intrahepatic cholangiocarcinoma (ICC). However, its phenotype and related spatial structure remained elusive. To address these limitations, we undertook a comprehensive study combining spatial data (29,632 spots from six samples) and single-cell data (21,158 cells from 35 samples).

Spatial analyses revealed S100P + TFF1 + tumor cells in spread through air spaces samples correlated with undesirable therapy response in non-small cell lung cancer.

Spread through air spaces (STAS) is a recognized aggressive pattern in lung cancer, serving as a crucial risk factor for postoperative recurrence. However, its phenotype and related spatial structure have remained elusive. To address these limitations, we conducted a comprehensive study based on spatial data, analyzing over 30,000 spots from 14 non-STAS samples and one STAS sample.
