FAP-targeted radioligand therapy with 68Ga/177Lu-DOTA-2P(FAPI)2 enhance immunogenicity and synergize with PD-L1 inhibitors for improved antitumor efficacy

Background
Fibroblast activation protein (FAP)-targeted radioligand therapy, with immunomodulatory effects, has shown efficacy in both preclinical and clinical studies. We recently reported on a novel dimeric FAP-targeting radiopharmaceutical, 68Ga/17…

Early assessment of IL8 and PD1+ Treg predicts response and guides treatment monitoring in cemiplimab-treated cutaneous squamous cell carcinoma

Purpose
Anti-programmed cell death 1 (PD1) is the first-choice treatment in patients with advanced cutaneous squamous cell carcinoma (cSCC), when curative options are unavailable. However, reliable biomarkers for patient selection are still lacking.

Radiomics signature for dynamic monitoring of tumor inflamed microenvironment and immunotherapy response prediction

Background
The efficacy of immune checkpoint inhibitors (ICIs) depends on the tumor immune microenvironment (TIME), with a preference for a T cell-inflamed TIME. However, challenges in tissue-based assessments via biopsies have triggered the explorati…

Chemotherapy-induced cellular senescence promotes stemness of aggressive B-cell non-Hodgkins lymphoma via CCR7/ARHGAP18/IKB{alpha} signaling activation

Background
Resistance to existing therapies is a major cause of treatment failure in patients with refractory and relapsed B-cell non-Hodgkin’s lymphoma (r/r B-NHL). Therapy-induced senescence (TIS) is one of the most important mechanisms of dru…

Nivolumab plasma concentration and clearance associated with overall survival in patients with renal cell carcinoma

Background
Nivolumab is an immune checkpoint inhibitor (ICI) that selectively inhibits programmed cell death protein 1 activation, restoring antitumor immunity. ICIs are indicated for various types of advanced solid tumors; however, not all patients b…

CREB3L1 facilitates pancreatic tumor progression and reprograms intratumoral tumor-associated macrophages to shape an immunotherapy-resistance microenvironment

Background
To date, a growing body of evidence suggests that unfolded protein response (UPR) sensors play a vital role in carcinogenesis. However, it remains unclear whether they are involved in pancreatic ductal adenocarcinoma (PDAC) and how they rel…

Lethal clinical outcome and chemotherapy and immunotherapy resistance in patients with urothelial carcinoma with MDM2 amplification or overexpression

Background
The E3 ubiquitin ligase murine double minute 2 (MDM2) binds the p53 transcriptional activation domain and acts as a potent inhibitor of TP53 pathway, one of the three most crucial oncogenic pathways in urothelial carcinoma (UC). However, th…

SIGLEC11 promotes M2 macrophage polarization through AKT-mTOR signaling and facilitates the progression of gastric cancer

Background
Sialic acid-binding immunoglobulin-like lectins (SIGLECs) are widely expressed on immune cell surfaces, play an important role in maintaining immune homeostasis and regulating inflammatory responses, and are increasingly emerging as potenti…

Effect of radiotherapy exposure on fruquintinib plus sintilimab treatment in refractory microsatellite stable metastatic colorectal cancer: a prospective observation study

Background
Immune checkpoint inhibitors (ICIs) in combination with antiangiogenic drugs have shown promising outcomes in the third-line and subsequent treatments of patients with microsatellite stable metastatic colorectal cancer (MSS-mCRC). Radiother…

Spatial and single-cell transcriptomics reveal cellular heterogeneity and a novel cancer-promoting Treg cell subset in human clear-cell renal cell carcinoma

Background
Clear cell renal cell carcinoma (ccRCC) is the most common histologic type of RCC. However, the spatial and functional heterogeneity of immunosuppressive cells and the mechanisms by which their interactions promote immunosuppression in the …
