BACKGROUND. Therapeutic vaccinations against cancer have mainly targeted differentiation antigens, cancer-testis and overexpressed antigens thus far resulted in little clinical benefit. Studies conducted by multiple groups demonstrated that T cells recognizing neoantigens are present most cancers offer a specific highly immunogenic target for personalized vaccination.

Background Cellular immunotherapies using autologous tumor-infiltrating lymphocytes (TIL) can induce durable regression of epithelial cancers in selected patients with treatment-refractory metastatic disease. As the genetic engineering T cells tumor-reactive T-cell receptors (TCRs) comes to forefront clinical investigation, rapid, scalable, and cost-effective detection patient-specific neoantigen-reactive TIL remains a top priority. Methods We analyzed single-cell transcriptomic states 31...

Background: Peritoneal carcinomatosis historically has a poor prognosis; however, Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) have shown improved outcomes. While volume-outcome relationship is established in oncologic surgeries, its applicability to CRS/HIPEC remains unexplored. This study examines the impact of hospital volume on Methods: Using national Vizient Clinical Database, this retrospective analysis evaluated 5,165 HIPEC cases from 149 hospitals...

Background Synthetic cannabinoids are a recreational drug that can cause toxicity with significant side effects. Case We report 21-year-old incarcerated male delayed presentation of pneumothorax, pneumomediastinum, and pneumoperitoneum following synthetic cannabinoid use altered mental status. Discussion This case not only highlights the need to consider pneumothorax when evaluating but it also emphasizes vulnerable population (incarcerated individuals at risk for trauma, substance...

Abstract The adoptive transfer of tumor-infiltrating lymphocytes (TILs) expanded in vitro can mediate regressions established tumors, yet only a minority intratumoral T cells are reactive to cancer antigens while the majority represent bystander cells. This complexity underpins need phenotypically characterize infiltrating tumor microenvironment. In this study, we performed single-cell RNA and cell receptor (TCR) sequencing (scRNA/TCR-seq) on over 45,000 isolated from ten archival metastatic...

Abstract Adoptive cell therapy (ACT) targeting neoantigens can achieve durable clinical responses in patients with cancer. Most arise from rare mutations, requiring highly individualized treatments. To broaden the applicability of ACT neoantigens, we focused on TP53 mutations commonly shared across different cancer types. Here, describe a library T receptors (TCRs) that target among 7.3% solid cancers. These TCRs recognized tumor cells mutation- and human leucocyte antigen (HLA)-specific...
