Filter by:Primary liver cancer is one of the most common malignant tumor and leading cause of cancer-related death worldwide. Basically therapeutic strategies were considered and given based on the staging of liver cancer. Thus, the confirmatory diagnosis of numbers and distribution of malignant lesions were extreme important. Enhanced CT or MRI is routinely imaging scans to detect and identify lesions. Unfortunately, some malignant lesions usually presented untypical imaging characteristics, especially among lesions no larger than 1 cm, which misleading to the exact staging of liver cancer and the optimal therapeutic strategies. Basically most of blood supply for malignant liver tumors is from the hepatic artery. Based on this fact, hepatic arterial digital subtraction angiography could potentially elevate the accuracy and sensitivity of detection malignant lesions numbers and distribution. In this study the investigators will compare the numbers and distribution of malignant lesions before and after hepatic arteriography, then to revise the staging of liver cancer and to provide better therapeutic strategies.
Hepatocellular carcinoma (HCC) is the most frequent primary tumour of the liver and is the third cause of cancer-related mortality worldwide. Depending on the stage of the disease, the treatment options are surgery, liver transplantation, chemotherapy or radiotherapy. Recently, scientific research has focused on small molecules called microRNAs which are produced by human cells and can be released in the blood. They have a role in cell proliferation and are found to be dysregulated in different types of cancer. It has been shown that microRNAs have a role in the development of HCC but it is unknown if these molecules can be used as markers for diagnosis and survival in HCC. In particular, microRNAs miR-221 and miR-222 are dysregulated in the tumoral tissues in about 80% of patients with HCC. This can be assessed on tissues from liver biopsies or surgical specimens, both invasive approaches. Only few studies showed the presence of microRNAs in the blood of patients with HCC but it is unknown if there is a correlation between tumoral tissue expression and circulating levels. The aim of this study is to evaluate if these two microRNAs are expressed not only in the tumoral tissues but also in the blood from cancer patients, and in different amounts compared to circulating levels in healthy individuals. A correlation between tumoral tissue and blood levels will also be evaluated. Should this evaluation show a strong correlation and reliability of circulating microRNAs in the diagnosis and follow up of HCC, future clinical trials targeting these microRNAs and their related pathways might benefit from this being adopted as conventional practice instead of the need of assessing tissue levels from liver biopsies. The results of this pilot study will bring preliminary results as a first step for future analysis on a larger cohort of patients.
Till now, trans-arterial chemoembolization (TACE) is still one of the common modalities in treating hepatocellular carcinoma patients with unresectable intermediate stage. However, residual viable HCC after TACE is not uncommon, leading to a poor overall survival after TACE alone. Recently, stereotactic ablative radiotherapy (SABR) has been reported to be potentially useful for curatively managing early-stage HCC in retrospective studies. Thus, conducting a randomized clinical trial to test the role of SABR in eradicating post-TACE residual tumors is therefore encouraged. The present phase-III trial intended to compare clinical outcomes between TACE + SABR and TACE + re-TACE for HCC patients with post-prior-TACE residual tumors.
Patients having surgery to remove a liver or biliary tissue mass or having a biopsy of a mass or lesion will have a tissue sample collected and stored for future research of liver and biliary diseases. A blood sample may also be collected at the time of enrollment.
Background: Combinations of dendritic and cytokine-induced killer cell (D-CIK) based adoptive immunotherapy and anti-PD-1 antibody may enhance the immune response and stop cancer cells from growing. Objective: Phase II clinical trial to investigate the safety, clinical activity and toxicity of combinations of D-CIK and anti-PD-1 antibody in patients with treatment-refractory solid tumors. Methodology: Phase II clinical trial in patients with advanced metastatic hepatocellular carcinoma, renal cell carcinoma,bladder cancer,colorectal cancer,non-small-cell lung cancer,breast cancer and other solid cancers. The D-CIK was isolated from peripheral blood of participants,then activated,expanded and incubated with anti-PD-1 antibody before infusion. The enough number (1.0-1.5 *10^10 cells) of D-CIK were infused back into participants.
The purpose of this study is to evaluate the safety and effectiveness of CAR-pNK cell immunotherapy in patients with MUC1 positive relapsed or refractory solid tumor.
Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies.
This study is a randomized control prospective study. The aim of this study is to establish an all-round and convenient follow-up strategy of Chronic Hepatitis B for early detection and diagnosis of Hepatocellular Carcinoma (HCC), by investigating whether different surveillance time intervals and surveillance methods are beneficial for chronic hepatitis B and cirrhotic patients with different risk of HCC.
To assess the primary effects and safety of Anlotinib with placebo in patients with Hepatocellular Carcinoma(HCC).
The purpose of this study is to prospectively compare the clinical outcomes (local tumor progression rate, technical success rate, complication rate) of no touch radiofrequency ablation (RFA) technique for Hepatocellular carcinoma (HCC) to those of conventional tumor puncture RFA technique.
