Stefanie L Rashti
BACKGROUND: Solid-organ transplants provide a second chance to thousands of critically ill patients with end-organ failure each year. Immunosuppressants are administered to patients to prevent graft rejection of a transplanted organ, such as a heart, kidney, or liver, while placing the recipient at greater risk for infection and cancer. OBJECTIVE: The literature provides evidence of various cancers that have been found to develop in patients' posttransplantation...

Background: Stem cell units (SCUs) that are cryopreserved prior to both autologous and allogeneic hematopoietic stem cell transplants (for donor lymphocyte infusion) remain unused or partially used several times, and become an increased burden to blood banks/SCU repositories. Because of the scarcity of data regarding the duration for which the storage is useful, there is no general consensus regarding disposal of SCUs. Methods: We conducted a retrospective audit of SCU utilization in 435 patients who planned to undergo either autologous stem cell transplantation (auto-SCT) (N=239) or allogeneic stem cell transplantation (allo-SCT) (N=196) at a tertiary cancer care center between November 2007 to January 2015...

PURPOSE: One of the major challenges in delivering cytokines for the treatment of hepatocellular carcinoma (HCC) is the mode of delivery. This study hypothesized that genetically engineered bone marrow derived mesenchymal stem cells (BMSCs) co-expressing IFN-γ and IL-10 can serve as a potential therapeutic strategy in the treatment of HCC by inhibiting cell proliferation. METHODS: Male Sprague-Dawley rats (n=5, 200-250 g) for BMSCs isolation and Nude/SCID mice (n=35,12-20g) to develop liver cancer xenograft model were used...

BACKGROUND & AIMS: There is growing evidence that liver graft ischemia-reperfusion (I/R) is a risk factor for hepatocellular carcinoma (HCC) recurrence, but the involved mechanisms are unclear. Here, we tested the hypothesis that mesenteric congestion due to portal blood flow interruption induces endotoxin-mediated Toll-Like Receptor 4 (Tlr4) engagement, resulting in elevated liver cancer burden. We also assessed the role of remote ischemic preconditioning (RIPC) in this context. METHODS: C57Bl/6j mice were exposed to standardized models of liver I/R injury and RIPC, by occluding hepatic and femoral blood vessels...

Fluorescence-activated cell sorting (FACS) is a common method to identify and to isolate subpopulations within a complex mixture of cells based on their light scatter and fluorescent staining profiles. FACS is widely used to enrich for normal tissue and tumor cells that have stem cell potential. Whereas FACS protocols using conventional breast cancer cell lines are relatively routine, additional technical challenges are encountered when sorting for cell populations from freshly digested solid tumors, particularly for use in downstream cancer stem cell (CSC) assays...

This study aimed to investigate whether lidocaine, alone or in combination with other chemotherapeutic agents, inhibits the growth of human bladder cancer cells in vitro and orthotopically transplanted bladder tumors in vivo. The effects of lidocaine (1.25, 2.5 or 5 mg/mL), mitomycin C (MMC, 0.66 mg/mL), pirarubicin (0.75 mg/mL) and Su Fu'ning lotion (SFN, 0.0625 mg/mL) on the proliferation of human bladder cancer (BIU-87) cells were studied using the MTT assay. A Balb/c nude mouse model of bladder cancer was developed by orthotopic transplantation of BIU-87 cells, and the effects of intravesical instillation of lidocaine and MMC on bladder wet weight (a measure of tumor size) and survival (over 60 days) were studied...

Bloodstream infections (BSI) and Clostridium difficile infections (CDI) in pediatric oncology/hematology/bone marrow transplant (BMT) populations are associated with significant morbidity and mortality. The objective of this study was to explore possible associations between altered microbiome composition and the occurrence of BSI and CDI in a cohort of pediatric oncology patients. Stool samples were collected from all patients admitted to the pediatric oncology floor from Oct.-Dec. 2012. Bacterial profiles from patient stools were determined by bacterial 16S rRNA gene profiling...

Cryopreservation of immature testicular tissue before chemo/radiotherapy is the only option to preserve fertility of cancer-affected prepubertal boys. To avoid reintroduction of malignant cells, development of a transplantable scaffold by decellularization of pig immature testicular tissue (ITT) able to support decontaminated testicular cells could be an option for fertility restoration in these patients. We, therefore, compared decellularization protocols to produce a cytocompatible scaffold. Fragments of ITT from 15 piglets were decellularized using three protocols: sodium dodecyl sulfate (SDS)-Triton (ST), Triton-SDS-Triton (TST) and trypsin 0...

Esophageal cancer is a common malignant tumor worldwide. Inherent and acquired drug resistance are the major challenges faced in anticancer chemotherapy. This study aimed to explore the effects of α-solanine in regards to the chemosensitivity of esophageal cancer cells. We found that α-solanine enhanced the sensitivity of EC9706 and KYSE30 cells to 5-flurouracil (5-FU) and cisplatin (Cis) by promoting drug-induced apoptosis. qRT-PCR and western blotting results showed that α-solanine treatment promoted miR-138 expression and decreased survivin expression in EC9706 and KYSE30 cells...

AIM: Recently, many reports showed that the pretransplant neutrophil-lymphocyte ratio (NLR) may be correlated with the prognosis of patients undergoing liver transplantation (LT) for hepatocellular cancer (HCC). However, their results still remained controversial. Thus we performed a meta-analysis of 13 studies to estimate the prognostic value of pretransplant NLR. METHODS: Databases including PubMed, Embase, Cochrane Library and Web of Science were searched to September 2017...

Primary liver cancer-including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC)-incidence is increasing and is an important source of cancer-related mortality worldwide. Management of these cancers, even when localized, is challenging due to the association with underlying liver disease and the complex anatomy of the liver. Although for ICC, surgical resection provides the only potential cure, for HCC, the risks and benefits of the multiple curative intent options must be considered to individualize treatment based upon tumor factors, baseline liver function, and the functional status of the patient...

Cancer immunotherapy has shown remarkable recent progress. Immune checkpoint blocking antibodies have become the most successful anti-cancer agent class ever developed, with six distinct agents approved since 2011 for a wide variety of cancers. Although age is the biggest risk factor for cancer (aside from selected early-onset pediatric cancers), these agents were tested pre-clinically in young hosts, and there is remarkably little published on the effects of host age on treatment outcomes in pre-clinical studies or human clinical trials...

Severe combined immunodeficiency (SCID) is defined by the lack of an adaptive immune system. Mutations causing SCID are found naturally in humans, mice, horses, dogs, and recently in pigs, with the serendipitous discovery of the Iowa State University SCID pigs. As research models, SCID animals are naturally tolerant of xenotransplantation and offer valuable insight into research areas such as regenerative medicine, cancer therapy, as well as immune cell signaling mechanisms. Large-animal biomedical models, particularly pigs, are increasingly essential to advance the efficacy and safety of novel regenerative therapies on human disease...

PURPOSE OF REVIEW: Since the first liver transplantation in the early 1960s, there have been significant improvements in the recipients' long-term outcome. Patients who have undergone transplantation are exposed to a high risk of developing neoplastic disease, not only because of their chronic immunosuppression, but also related to physiological aging, lifestyle, chronic viral infections, liver disease cause, and carcinogenic immunosuppressants. The present review covers the latest and most relevant data on de novo neoplasms after liver transplantation, and discusses their implications for clinical practice...

Transplantation of immune cells manipulated in vitro to dictate immune responses in the body is promising in cancer immunotherapy. However, this approach suffers from low cell survival after administration, insufficient cell homing to lymph nodes, and off-target. Here we demonstrate an injectable and self-assembled poly(l-valine) hydrogel as the delivery carrier of cargoes including antigen and immunopotentiator for DCs modulation. Our results indicate the vaccine formulation composed of tumor cell lysates (TCL), TLR3 agonist, poly(I:C) and polypeptide hydrogel can robustly recruit, activate and mature DCs in vitro and in vivo by sustained release of TCL and poly(I:C)...

CONTEXT: Liver cancers (including hepatocellular carcinoma [HCC] and cholangiocarcinoma) are the fifth most common cause of cancer death. The most powerful independent histologic predictor of overall survival after transplantation for HCC is the presence of microscopic vascular invasion (VI). AIMS: Given that VI is known to have somewhat high interobserver variability in both HCC and other tumors, we hypothesized that pathologists with special interest and training in liver pathology would be more likely to identify and report VI in HCC than would general surgical pathologists...

PURPOSE: Prolonged and profound neutropenia is common among hematology and hematopoietic stem cell transplant (HSCT) patients as a result of chemotherapy. The National Comprehensive Cancer Network (NCCN) and Infectious Diseases Society of America (IDSA) currently recommend antibacterial prophylaxis in patients who are deemed at intermediate or high risk for infection. Specifically, fluoroquinolone prophylaxis should be considered for high-risk neutropenic patients. However, with prolonged and frequent exposure to fluoroquinolones, these high-risk patients may develop resistance to these agents...

Intermediate-risk acute myeloid leukemia (IR-AML) is a clinically heterogeneous disease, for which optimal post-remission therapy is debated. The utility of next-generation sequencing information in decision making for IR-AML has yet to be elucidated. We retrospectively studied 100 IR-AML patients, defined by European Leukemia Net classification, who had mutational information at diagnosis, received intensive chemotherapy and achieved complete remission (CR) at Cleveland Clinic (CC). The Cancer Genome Atlas (TCGA) data were used for validation...

Hematopoietic stem cell transplantation (SCT) recipients are exposed to a large amount of anti-cancer drugs, immunosuppressors, and irradiation during the peri-SCT period. Thus, they have to overcome serious adverse events related to unavoidable but toxic procedures, including organ disorders. In particular, acute kidney injury (AKI) is one of the most critical complications, because it influences the mortality of patients. A few patients who survive AKI may develop nephrotic syndrome, and precedent AKI is also closely associated with chronic and progressive loss of the renal function in post-SCT patients...
