Lymph node metastasis (LNM) drastically reduces survival after resection of intrahepatic cholangiocarcinoma (IHC). Optimal treatment is ill defined, and it unclear whether tumor mutational profiling can support decisions.Patients with liver-limited IHC or without LNM treated (N = 237), hepatic arterial infusion chemotherapy (HAIC; N 196), systemic alone (SYS; 140) at our institution between 2000 2018 were included. Genomic sequencing was analyzed to determine genetic alterations could...

Guidelines recommend vaccination starting 12 months after autologous hematopoietic stem cell transplant (aHCT), but there is varying practice for patients on maintenance therapy, with some centers not immunizing at all. Because of decreased vaccine rates among the general population causing loss herd immunity, we aimed to establish safety and efficacy revaccinating multiple myeloma lenalidomide (LM). Of 122 who were vaccinated aHCT between 2010 2014 Memorial Sloan Kettering Cancer Center, 91...

Abstract Understanding the molecular and phenotypic profile of colorectal cancer (CRC) in West Africa is vital to addressing regions rising burden disease. Tissue from unselected Nigerian patients was analyzed with a multigene, next-generation sequencing assay. The rate microsatellite instability significantly higher among CRC (28.1%) than Cancer Genome Atlas (TCGA, 14.2%) Memorial Sloan Kettering Center (MSKCC, 8.5%, P &lt; 0.001). In microsatellite-stable cases, tumors are less likely have...

Objective: To evaluate whether patient-controlled epidural analgesia (PCEA) improves postoperative pain during ambulation following elective open hepatectomy. Background: Strategies to alleviate are a critical element of recovery after surgery. However, the optimal management strategy hepatectomy remains unclear. Methods: We conducted prospective, non-blinded, randomized comparison PCEA (intervention) vs. intravenous (IV PCA; control) for The primary endpoint was on day (POD) 2. study...

640 Background: Pancreatic ductal adenocarcinoma (PDAC) remains a challenging disease due to its aggressive nature, late-stage diagnosis, and limited treatment options. There is an increased interest in cancers which harbor microsatellite instability (MSI) their susceptibility immune checkpoint inhibitors. MSI PDAC rare, little known about survival this subtype of pancreas cancers. Our aim was assess overall surgically resected high (MSI-H), mismatch repair deficient (MMRd), Lynch Syndrome...

Abstract Purpose: Survival of patients with metastatic sarcoma remains poor, and there is a pressing need for new therapies. Most subtypes are not responsive to immune checkpoint inhibition alone. Lenvatinib, multireceptor tyrosine kinase inhibitor targeting tumor vasculature, has an immunomodulatory activity that contributes its antitumor effects. Therefore, we hypothesized combination lenvatinib pembrolizumab would lead improved clinical outcomes in sarcoma. Patients Methods: This was...

11552 Background: Liposarcomas (LPS) are among the most common soft tissue sarcoma subtypes. Well-differentiated (WD) and dedifferentiated (DD) LPS characterized by CDK4 MDM2 amplification. Both subtypes have variable sensitivity to chemotherapy. However, effective systemic treatment options remain limited for unresectable or metastatic disease. Our group previously reported two phase 2 trials of CDK4/6 inhibitor (CDK4/6i) palbociclib (PD0332991) in advanced WD/DD LPS, which established...

Abstract The association between immune-related AEs (irAE) and outcome in patients with sarcoma is not known. We retrospectively reviewed a cohort of advanced treated immune checkpoint blockade (ICB)-based therapy. Association irAEs survival was assessed using Cox regression model that incorporated irAE occurrence as time-dependent covariate. Tumor samples available RNA sequencing data were stratified by presence an to identify patterns differential gene expression. A total 131 included....
