Active clinical trials for "Neoplasms"

The recent approval of ICB treatments targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death-1 (PD-1/PD-L1) by the US Food and Drug Administration has offered an improved treatment chance for a variety of malignant tumors, including those with a particularly poor prognosis. However, a growing number of studies and case reports show that immunotherapy may accelerate tumor progression in a significant subset of patients ranging from 9% to 27% across multiple histologies and lead to so-called hyperprogressive disease (HPD) that leads to a rapid patient death. During this NIS study, Asylia Diagnostics aims to fill in the first layer of knowledge leading to the identification of predictive biomarkers and biological mechanisms that could be used for the prediction, diagnosis, and treatment of melanoma and NSCLC HPD patients. The study is a retrospective clinical study. During this study basic historical medical information and scrolls from FFPE-preserved biopsies taken prior to immunotherapy treatment will be collected. The nature of the study is not invasive and non interruptive to the standard of care.

PD-1/PD-L1 blockades have attracted much attention in the treatment of lung cancer, however only a small set of patients can benefit from this kind of immunotherapy. At present, the expression level of PD-L1 is the major factor to evaluate the prognosis，, which is highly dependent on the quality of tissue samples and detection methods.Therefore, finding predictive markers,especially based on liquid biopsy, to screen the patients who will benefit most from PD-1/PD-L1 blockades is an urgent issue in immunotherapy for lung cancer. Tumor autoantibodies, as immune response products of the immune system to tumor antigens, are of great significance in tumor diagnosis. Till now, the relationship between tumor autoantibodies and immunotherapy efficacy has not been reported. In this study, 200 non-small cell lung cancer patients will be enrolled with baseline serum tumor autoantibodies detection, then treated with PD-1 blockade. The purpose of this study is to explore the correlations of serum autoantibodies expression and efficacy of PD-1 inhibitor, so that to identify new markers for predicting the efficacy of PD-1/PD-L1 immunotherapy in non-small cell lung cancer.

A multicentre randomized health services study within the population-based primary colonoscopy screening program (PCSP) in Poland. Individuals, aged 55-60 years, willl be randomized in a 1:1:1 ratio to arms: (1) Invitation by post, (2) Call Center or (2) Combined invitation methods. The primary outcome measure is rate of participation in screening colonoscopy. The sample size of 6 300 participants will detect 3 to 5 percentage point differences (depending on the arms comparison) in participation rate between groups with 80% power and significance level 0.05, using Ochran-Mantel-Haenszel test.

This is an observational, ambispective cohort study. The aim is to compare the efficacy and safety of regorafenib versus fruquintinib conducted in China. About 268 eligible metastatic colorectal cancer patients after second-line therapy will be assigned to receive either regorafenib or fruquintinib, based on decision of the gastrointestinal physician according the patients' condition.

To investigate the clinical effect of radiofrequency ablation on colorectal cancer liver metastases with different KRAS gene status

The primary purpose is to investigate the relationship between the dose of chemotherapeutic agents per kilogram of lean body mass (LBM) and the development of side effects induced by chemotherapy in patients with lymphoma. Secondarily, the maximum tolerable dose of chemotherapeutics (MTD), patients' quality of life (QOL), nutritional status and physical activity during the course of treatment are estimated.

Esophageal cancer (EC) is the seventh most frequently diagnosed cancers and the sixth leading causes of cancer death worldwide . It is one of the most common malignancy in China, with the third highest morbidity and mortality rate. More than 90% of patients with EC in China have esophageal squamous cell carcinoma (ESCC). Neoadjuvant chemoradiotherapy (nCRT) followed by surgery is currently widely used strategy for locally advanced surgical EC. At present, conventional imaging methods have certain defects (focus only on the volume change) in the evaluation of the efficacy of nCRT. Whereas functional imaging can more comprehensively reflect the biological and microstructural characterization of tumors. The changes of these aspects of tumors can be observed earlier than volumetric changes of tumors. The normal metabolism of the body is the basis for ensuring life activities. Due to the increased energy demand and proliferation of tumor tissue in patients with cancer, the metabolism of patients is different from that of normal person. Thus, the metabolic alterations seen in cancer cells have emerged as one of the hallmarks of cancer. Previous metabolomic studies have demonstrated various metabolic alterations in patients with ESCC. Many metabolites have been found to be promising diagnostic, staging or prognostic biomarkers for ESCC. However, there are few studies on metabolic markers on the chemoradiation sensitivity of esophageal cancer. Therefore, the aim of the present study is to evaluate the value of functional imaging parameters and metabolic markers in assessing and predicting pathological response in patients who underwent nCRT for ESCC.

Local control rates of nasopharyngeal carcinoma are increasing, but 15% of patients still have local recurrence within 5 years after initial treatment. Systematic treatment based on chemotherapy has become the mainstream approach for recurrent nasopharyngeal carcinoma which is intolerant to local therapy. we sought to find an efficient chemotherapy regimen with high tolerance according to the characteristics of chemotherapy drugs, that is, to explore the efficacy and safety of platinum plus 5-fluorouracil with continuous intravenous infusion at a low dose for a long term.

The current first-line treatment for HBV is long-term oral antiviral drugs to inhibit HBV DNA replication. First-line antiviral drugs recommended by the Chinese 2015 Hepatitis B Guidelines include ETV and TDF. This study is based on a real-world clinical cohort to retrospectively analyze the effects of ETV and TDF on the long-term (5-year) incidence of HCC in Chinese patients with chronic hepatitis B with compensated cirrhosis. The results will guide the revision of the Chinese HBV guidelines.

Liver cancer is a common malignant tumor in China, and its incidence rate ranks third and remains high. The treatment of liver cancer has made some progress in recent years, mainly the progress of radical treatment such as surgery and ablation. For liver cancer, due to the emergence of molecularly targeted drugs such as sorafenib and immunological checkpoint inhibitors, the systemic therapeutic effect of advanced liver cancer is improved, and the curative effect is further improved. In recent years, immunotherapy has become one of the clinical treatment options for cancer. T lymphocytes are a cell with cell killing ability in the immune system, and programmed death factor 1 (PD-1) is an important inhibitory receptor on the surface of T lymphocytes. It is known that the ligands of PD-1 are PD-L1 and PD-L2, and studies have found that a variety of tumor cells have high expression of PD-L1 ligand on the surface. At present, clinical research on target drugs for PD-1 has included dozens of solid tumors or hematological tumors. The results of clinical studies that have been completed and the interim results of some studies indicate that anti-PD-1 antibody drugs are more effective and safer than previous treatments. Patients with hepatocellular carcinoma (HCC) often undergo liver cancer resection, but the recurrence rate can reach 70% to 100%, which seriously affects the treatment outcome and long-term survival rate. Early recurrence of liver cancer is mainly related to the invasiveness of the tumor. Microvascular invasion, non-anatomical hepatectomy, AFP greater than 32 ng/ml, tumor diameter greater than 5 cm, and incomplete tumor capsule are risk factors for recurrence within 2 years after surgery. Hence, it is necessary to determine the risk factors for HCC recurrence and the markers for continuous monitoring of anti-tumor response before and after surgery. Circulating tumor cells (CTCs) is an integral part of "liquid biopsy" and has great potential to change the current treatment modality in the cancer field. CTCs are derived from solid tumors and are associated with hematogenous metastasis. Therefore, analyzing the level of CTC has clinical guiding significance. For liver cancer patients, overall survival (OS) tended to be poorer in patients with CTCs. Although surgical treatment of liver cancer has benefited most patients with liver cancer, monitoring postoperative recurrence, further improving the long-term prognosis of liver cancer, postoperative detection of CTCs and other related indicators, combined with targeted, immune and other related treatments for further study. It is expected to receive 100 patients (50 treatment groups, 50 control groups). Patients who underwent immunotherapy after surgery were assigned to the immunotherapy group, and patients who were not treated with sorafenib after surgery were classified as the control group. All patients underwent 7 CTCs tests (immunomagnetic beads negative enrichment-targeted PCR) before, 7 days after surgery and 1st, 3rd, 6th, 9th, and 12th postoperatively. All patients were observed from the observation period. After the liver cancer resection, the patient was observed to have died, lost to follow-up or the end of the study.
