In conclusion, combined checkpoint inhibition therapy warrants further study in the salvage setting in patients with epithelioid and other INI1 protein–deficient sarcomas seemingly regardless of prior therapy, extent of disease, and performance status.

Bladder cancer (BC) is the 10th most common cancer worldwide. Approximately one quarter of patients with BC have muscle-invasive disease (MIBC). Muscle-invasive disease carries a poor prognosis and choosing the optimal treatment option is critical to improve patients’ outcomes. Ongoing research supports the role of 2-deoxy-2-(18F)fluoro-D-glucose positron emission tomography (18F-FDG PET) in guiding patient-specific management decisions throughout the course of MIBC. As an imaging modality, 18F-FDG PET is acquired simultaneously with either computed tomography (CT) or MRI to offer a hybrid approach combining anatomic...

Abstract Biochemically recurrent prostate cancer represents a stage of prostate cancer where conventional (continued on next page) computed tomography and technetium Tc 99m bone scan imaging are unable to detect disease after curative intervention despite rising prostate-specific antigen. There is no clear standard of care and no systemic therapy has been shown to improve survival. Immunotherapy-based treatments potentially are attractive options relative to androgen deprivation therapy due to the generally more favorable side-effect profile. Biochemically recurrent prostate cancer patients have a low tumor burden...

Rationale: The clinical application of biomarkers reflecting tumor immune microenvironment is hurdled by the invasiveness of obtaining tissues despite its importance in immunotherapy. We developed a deep learning-based biomarker which noninvasively estimates a tumor immune profile with fluorodeoxyglucose positron emission tomography (FDG-PET) in lung adenocarcinoma (LUAD).Methods: A deep learning model to predict cytolytic activity score (CytAct) using semi-automatically segmented tumors on FDG-PET trained by a publicly available dataset paired with tissue RNA sequencing (n = 93). This model was validated in two independen...

The metabolic properties of tumor microenvironment (TME) are dynamically dysregulated to achieve immune escape and promote cancer cell survival. However, in vivo properties of glucose metabolism in cancer and immune cells are poorly understood and their clinical application to development of a biomarker reflecting immune functionality is still lacking.Methods: We analyzed RNA-seq and fluorodeoxyglucose (FDG) positron emission tomography profiles of 63 lung squamous cell carcinoma (LUSC) specimens to correlate FDG uptake, expression of glucose transporters (GLUT) by RNA-seq and immune cell enrichment score (ImmuneScore). Si...

In this study, mannose-functionalized antigen nanoparticles with endosome escape activity were designed for targeted DCs, accelerated endosomal escape and enhanced MHC-I antigen presentation for cancer immunotherapy. Mannose was selected as DCs targeting ligand to enhance antigen uptake. Model antigen ovalbumin (OVA) was directly conjugated with mannose to obtain DCs targeting antigen, which was then complexed with polyethylenimine (PEI) through electrostatic interaction to form mannose-functionalized antigen nanoparticles (MAN-OVA/PEI NPs). Flow cytometry analysis revealed that the MAN-OVA/PEI NPs greatly increased antige...

It has become evident that positron emission tomography/computed tomography (PET-CT) using 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) (FDG PET-CT) can detect anti-tumor immune response induced by various immunotherapies. To evaluate whether FDG PET-CT could detect anti-cancer immune response caused by cancer vaccine therapy, we performed a retrospective analysis of FDG PET-CT imaging of patients who were treated with Wilms Tumor 1 (WT1) vaccine therapy in Osaka University during July 2008 and June 2018. Increased FDG uptakes were detected in WT1-vaccinated skin and their draining lymph nodes during the repeated vaccination. Wh...

Abstract Programmed cell death protein-ligand 1 (PD-L1) is a crucial biomarker in immunotherapy and its expression level plays a key role in the guidance of anti-PD-L1 therapy. It had been reported that PD-L1 was quantified by noninvasive imaging with more developed radiotracers. In our study, a novel [18F]fluoride labeled small molecule inhibitor, [18F]LN was designed for positron emission tomography (PET) imaging in both PD-L1 transfected (A375-hPD-L1) and non-transfected (A375) melanoma-bearing mice. LN showed the specificity (IC50 = 50.39 ± 2.65 nM) to PD-L1 confirmed by competitive combination and cell...

Abstract In an asymptomatic 77-yearold woman, former 55 packyears smoker, a routine X-ray showed a 45-mm superior left lobe lesion. A chest CT scan confirmed a 36-mm superior left lobe lesion and an aortic-pulmonary lymph node enlargement measuring 42 mm, suspicious for neoplasia. A PET-CT scan showed an elevated uptake in the primary lesion, in the aortic-pulmonary lymph node, and in the left hilar lymph node with a standardized uptake value - 40 and 4.3, respectively. CT-guided lung biopsy showed a lung squamous cell carcinoma. An endobronchial ultrasound-guided transbronchial needle aspiration for lymph-node st...
