Adoptive T-cell therapy for HBV-associated HCC and HBV infection

Publication date: Available online 19 February 2020Source: Antiviral ResearchAuthor(s): Anthony T. Tan, Sophia SchreiberAbstractChronic hepatitis B virus (HBV) infection remains a major global concern due to its high prevalence and the increased probability of progressing toward cirrhosis and hepatocellular carcinoma (HCC). While currently available therapies are effective in controlling HBV replication, they rarely achieve functional cure. Similarly, effective treatment options for HBV-related HCC (HBV-HCC) are limited and primarily applicable only for early stages of the disease. With the general success of chimeric antigen receptor T-cell immunotherapy against B-cell leukemia, adoptively transferring engineered autologous T cells specific for HBV or HCC antigens might represent a promising therapeutic approach for both chronic HBV infection and HBV-HCC. This review will describe the novel T cell-related immunotherapies being developed for both indications and discuss the approach of each strategy, their considerations and limitations when applied for treatment of chronic HBV infection (CHB) and HBV-HCC.

In this study the EGFR over‐expressing human head/neck OSC‐19‐luc2‐cGFP tumour with transfected GFP gen e was used in a skin‐fold window‐chamber model in BALB/c nude mice. The uptake and localization of the conjugate in the tumour and its surrounding normal tissues were studied by an intravital confocal laser scanning microscopy with image analyses. The tumour was also irradiated with 690 nm las er light 24 hours after conjugate administration. The vascular and tumour responses were examined by morphological evaluation and immunohistochemistry (IHC). The amount of conjugate in the tumour peaked at 24‐4...

Conclusion: In summary, analysis of currently available clinical evidence indicated that IMDC model could be applied to classify patients with metastatic renal cell carcinoma using targeted agents. However, different types of targeted agents and various areas could affect the accuracy of the model. There was also a difference in predicting patients' PFS and OS.

This study aims to evaluate the oncological and functional results of open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) at the T1b clinical stage, which constitutes 25% of renal cell carcinomas (RCC) at diagnosis. Materials and Methods: The characteristics of 63 patients with stage T1b solitary tumor who underwent OPN (41) or LPN (22) were compared. The survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the factors affecting disease-free survival. Potential predictive factors, which might affect the postopera...

ABSTRACT Introduction: Use of androgen deprivation therapy (ADT) in carcinoma prostate (CaP) has deleterious effect on bone mineral density (BMD) leading to increase incidence of osteoporosis and skeletal-related events. We evaluated bone health status and impact of bone-directed therapy (BDT) and ADT on BMD in these patients from Jan 2015-Dec 2018. Materials and Method: Baseline bone health was assessed using Tc-99 MDP Bone scan/ DEXA scan for patients on ADT. Monthly zoledronic acid (ZA) was given to high-risk candidates (T-score ≤ 2.5 or previous hip/vertebral fracture) or Skel et al. metastatic patients who were rec...

ABSTRACT Purpose: To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit. Materials and methods: Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, d...
