Telmisartan increases olaparib efficacy in homologous recombination proficient tumors by augmenting type I interferon production

Background
Poly-ADP ribose polymerase inhibitors (PARPi) are well-known to treat tumors that are deficient in homologous recombination (HR) DNA repair. However, PARPi can treat breast cancer gene (BRCA) wild-type tumors, the mechanisms behind which ar…

Targeting SPP1+TAMs associated with liver metastasis reverses immunosuppression and synergizes with immunotherapy in colorectal cancer

Background
Tumor-associated macrophages (TAMs) are critically involved in colorectal cancer (CRC) progression, yet their spatial and metabolic heterogeneity across primary and metastatic microenvironments remains poorly defined, limiting therapeutic d…

Phase II study of olaparib and durvalumab in patients with metastatic castration-resistant prostate cancer

Background
Poly(ADP-ribose) polymerase (PARP) inhibition (PARPi) is a precision medicine strategy in advanced prostate cancer, with the greatest benefit seen in a subset of patients with homologous recombination repair (HRR) gene alterations. Combinat…

Vaccinia virus armed with IL-21 can cure murine colorectal cancer liver metastases via intravenous administration

Background
Liver metastases of colorectal cancer are one of the leading causes of mortality in patients with colorectal cancer. Oncolytic virus immunotherapy has demonstrated significant potential in tumor treatment; however, most oncolytic viruses ar…

IL-12-secreting CAR-T cells reprogram the tumor microenvironment and improve efficacy against heterogeneous models of glioblastoma

Background
Glioblastoma (GBM) remains uniformly lethal due to pronounced intratumoral heterogeneity and a highly immunosuppressive microenvironment that limits the efficacy of targeted therapies.

Methods
We engineered chimeric antigen receptor (CAR) …

Targeted inhibition of Nrf2 potentiates antitumor immunity and enhances the efficacy of immunotherapy in hepatocellular carcinoma

Background
Immune checkpoint inhibitors (ICIs) and chimeric antigen receptor T-cell (CAR-T) immunotherapies have revolutionized the treatment of hepatocellular carcinoma (HCC). However, the frequent emergence of treatment resistance significantly limi…

Society for Immunotherapy of Cancer (SITC) clinical practice guideline on immunotherapy for the treatment of renal cell carcinoma, version 3.0

Immunotherapy has been a pillar of the renal cell carcinoma (RCC) treatment landscape for over three decades. Some of the earliest cancer immunotherapies available, such as interleukin 2 and interferon-alpha, have resulted in complete responses, but o…

Limited expression of B-cell maturation antigen in acute myeloid leukemia

B-cell maturation antigen (BCMA) was recently identified as a target of T-cell-directed therapy for acute myeloid leukemia (AML), based on the study reporting high BCMA abundance in AML cells using the flow cytometry anti-BCMA antibody clone 19F2 (BCM…

Fecal microbiota transplantation combined with anti-PD-1 therapy in refractory microsatellite-stable gastric cancer: a phase I feasibility and safety study

Background
The discovery and therapeutic application of immune checkpoint inhibitors (ICIs) have significantly improved clinical outcomes in cancer treatment. However, the response rate is still low in gastrointestinal (GI) cancers. The gut microbiome…

{gamma}{delta} T cells at the interface of innate and adaptive immunity in cancer

T cells are unconventional lymphocytes that bridge innate and adaptive immunity by combining recognition of stress-induced ligands independently of classical major histocompatibility complex molecules with the capacity to undergo clonal expansion and…
