Active clinical trials for "Carcinoma, Hepatocellular"

The purpose of this study is to evaluate the efficacy of ex vivo expanded autologous immune killer cells in treating hepatocellular carcinoma patients in： Reduction of tumor size Reducing the relapse rate: Reducing the frequency of TACE treatment by IKC injections.

The prognosis of small liver cancer (≤5 cm) who had underwent stereotactic body radiotherapy (SBRT) is encouraging, with the 1-year local control rate has been reported to be 95-100%, 3-year local control rate about 91%, 3-year overall survival rate around 70%. Local ablation therapy has become the standard treatment for recurrent liver cancer after surgery and interventional treatment. The ablation rate of tumors with a diameter of 3.1-5.0 cm reached 90%. The 1, 2, and 3-year survival rates had been reported to be 89%, 74%, and 60%, respectively, which is similar to that of surgical resection. At present, there is no randomized controlled study of SBRT and microwave ablation (MWA) for small liver cancer. It is hoped that this study will further compare the efficacy of SBRT and MWA for recurrent small hepatocellular carcinoma.

This single arm, open label, two stage study will be conducted in several medical centers around Taiwan. Stage one determine safety and tolerability in patients with HCC, and stage two assess anti-tumor activities of GT90001 in combination with nivolumab in patients with metastatic HCC. Subjects who fulfill all the entry criteria and have written informed consent will be enrolled to the study.

Hepatocellular carcinoma (HCC) is one of the malignant tumors that seriously threaten the health of people. Its morbidity and mortality rank the third and the second among various malignant tumors in China, respectively. Local ablation therapy represented by radiofrequency ablation (RFA) has been recommended as a first-line treatment for small HCC by most international guidelines. Especially for central small HCC, RFA is considered the first-line choice. With the advancement of radiotherapy equipment and the development of precise imaging technology, stereotactic body radiotherapy (SBRT) has become one of the important treatments for liver cancer.Retrospective controlled studies have shown that SBRT is similar to RFA in treating small HCC, and the local control rate may be better than RFA. But there is no high-level evidence to support which treatment is superior. This project aims to conduct a phase III, prospective, randomized, open, parallel controlled clinical study of RFA versus SBRT for small HCC (solitary tumor≤ 5.0 cm). The results will provide potent evidence for the rational and effective treatment of early HCC and the improvement of clinical guidelines for HCC.

SHR-1210 is a humanized anti-PD-1 Immunoglobulin G4 (IgG4) monoclonal antibody. This is an open- label#single center #non-randomized #Single Arm Exploratory Study . This clinical study is an investigator-initiated clinical trial(IIT) .The objective of this study is to evaluate the efficacy and safety of therapy with anti-PD-1 antibody SHR-1210 and apatinib in patients with advanced stage hepatocellular carcinoma.

To evaluate the efiicacy of TAI combine SBRT in unresectable HCC

To evaluate the efficacy of TAI combine toripalimab in advanced HCC.

The primary reason for recurrence of hepatocellular carcinoma after radiofrequency ablation (RFA) is the micro-metastatic lesion that has not been ablated and inactivated in the transitional area.Some clinical trials have confirmed that H101(recombinant human adenovirus type 5 injection) has selective oncolysis in a variety of solid tumors.However, there are no reports that H101 which is injected during surgery can improve the efficacy of RFA in liver cancer at present.Therefore,We used a multicenter prospective randomized controlled study as the main method to prospectively compare the short-term and long-term efficacy of RFA combined with H101 group and traditional RFA group in the treatment of small liver cancer (single lesion , diameter less than or equal to 3cm，to evaluate the value of RFA combined with H101 injection in reducing the postoperative recurrence rate of small hepatocellular carcinoma, and to provide a reliable evidence-based medical basis for the selection of treatment methods for small hepatocellular carcinoma.

A phase 1 study that aimed to assess the safety and anti-tumor activity of C-TCR055 injection in unresectable HCC patients.

Liver cancer is a clinically high-grade malignant tumor, and the current incidence rate is increasing year by year. It has become the third most malignant tumor after gastric cancer and lung cancer, and has a high mortality rate. The patient's five-year survival rate is less than 8.5%, which the second leading cause of cancer death is a serious threat to the health of patients. Surgical resection is the preferred treatment plan for liver cancer. With the development of medical technology, the clinical efficacy of liver cancer has been significantly improved, but postoperative recurrence has not been effectively controlled. According to statistics, the recurrence rate of liver cancer after 5 years is as high as 77.0%. Even for small liver cancer resection, the recurrence rate is 40.0%~50.0% within 5 years after operation. At the same time, for recurrent liver cancer, surgical resection is still the preferred treatment plan, but affected by the location, size, distal metastasis and multi-center pathogenesis of liver cancer, only 10.4%~31.0% can be surgically removed. In recent years, RFA has been widely used in liver cancer and recurrent liver cancer due to its unique advantages such as minimally invasive, simple operation, wide indication, reproducible, low cost, and accepted by patients, and has achieved satisfactory results. However, study found that because of the special location of recurrent liver cancer, its multi-center origin, and the characteristics of intrahepatic micrometastasis, it is often accompanied by microvascular tumor thrombus (MVI), which greatly increases the risk of liver cancer recurrence. Moreover, since the treatment of RFA can only be effective for the local detection of recurrent foci, and the effect of detecting small lesions is poor, there is a higher risk of recurrence. The use of radiation therapy is getting more and more attention, and it is changing from the past palliative treatment to current curable treatment. From an oncologic point of view, a narrow margin <1 cm and microvascular invasion is not safe and is often associated with higher rates of recurrence and shorter patient survival. On the other hand, it is also believed that most intrahepatic recurrences arise from multicentric carcinogenesis and are distant from the resection margin. Whether combined radiotherapy and RFA treatment of liver cancer and recurrent liver cancer can further improve the clinical efficacy, there are few reports. Therefore, the short-term and long-term effects of radiotherapy combined with RFA in the treatment of liver cancer and recurrent liver cancer are studied to provide guidance for clinical treatment.
