Active clinical trials for "Neoplasm Metastasis"

The purpose of this study is to study the way radioembolization works by collecting biopsy samples of participants' tumors after the procedure. This research may improve the way that radioembolization is performed, which could help people whose cancer has spread to the liver. The research may also provide information about how tumors respond to radioembolization.

Oxidative stress is involved in the pathogenesis of thyroid cancer, but the mechanism is not clear. The thyroid is the organ with the most abundant selenium content, and selenium may be involved in protecting the gland from the influence of large amounts of H2O2 produced during thyroid hormone biosynthesis. Selenium may exert anti-tumor activity through a variety of mechanisms, including inducing apoptosis and anti-oxidation to change the DNA methylation state of tumor suppressor genes, cell cycle arrest and stimulation of the immune system, as well as playing an anti-tumor role through its anti-inflammatory and anti-angiogenesis properties. The whole blood and thyroid selenium concentrations in patients with thyroid cancer were lower, and the decreased serum selenium levels were also associated with the high TNM stage of thyroid cancer. According to the Nutrition Prevention of Cancer (NPC) trial, selenium yeast supplements with a daily selenium content of 200 MCG have been shown to reduce the incidence of total cancer, prostate cancer, colon cancer, and lung cancer, and cancer mortality. The active agent in selenium yeast supplements is known as selenium methionine (SEMET). In general, the association between selenium and thyroid cancer is still inconclusive, the question of whether low selenium is a predisposition factor or a consequence of thyroid cancer has not been resolved, and the clinical effect of selenium supplementation in preventing thyroid cancer or improving its prognosis remains to be studied. The hypothesis is that supplementation with selenium yeast will improve the prognosis of patients with differentiated alpha-carcinoma.

Liver metastases (MTS) are the main cause of death for patients affected by colorectal carcinoma (CRC) and pancreatic ductal adenocarcinoma (PDAC), thus representing the major unmet clinical need for these malignancies. Based on preliminary and published data, the investigators hypothesize that innovative immune, gene and cell therapy approaches might overcome the tolerogenic liver microenvironment and represent powerful therapeutic tools for liver MTS of PDAC and CRC. The investigators have therefore planned an observational clinical study to enroll distinct cohorts of patients (i.e., metastatic CRC, metastatic and non-metastatic PDAC) and finely characterize, through integrated state-of-the-art -omics, the immune and non-immune microenvironment of their primary tumor and/or liver metastases as well as correlate changes in the activation status and phenotype of peripheral blood leukocytes. Healthy volunteers will be enrolled as negative controls. The investigators aim at identifying: i) actionable tumor associated antigens (TAAs) and local immune suppressive and regulatory pathways; ii) biological parameters for early diagnosis of relapse; iii) the effect of therapies on the shaping of anti-tumor immune responses. Data collected will be instrumental for the generation of novel advanced therapy medicinal products (ATMPs). Indeed, this protocol is part of a multi-partner translational program, supported by the AIRC 5 per Mille 2019 grant, focused on the development, validation and implementation for clinical testing of ATMPs to ameliorate the cure of CRC and PDAC and possibly help the study of other solid tumors. Moreover, the systematic and long-term follow-up of enrolled patients will possibly point at early predictors of differential prognosis and patients' categories eligible for tailored therapies, including those with the novel ATMPs.

This is an observational study to investigate if it is feasible to recruit 100 patients receiving radiotherapy (RT) to metastatic disease to wear Hexoskin and if Hexoskin will facilitate the monitoring, detection and early treatment of RT-related side effects.

A Phase 1 study to evaluate the safety, tolerability, PK, immunogenicity, pharmacodynamics, and preliminary antitumor activity of AK114.

The incidence of brain metastases is expected to increase because of better treatments of primary tumours. Novel diagnostic and therapeutic techniques are continuously being developed, all of which need thorough evaluation before they can be implemented in clinical routine. Randomized Controlled Trials are the gold standard to do so, but they have shown many challenges, especially when applied in a cancer setting. .The 'cohort multiple Randomized Controlled Trial (cmRCT)' design is a promising design for multiple (simultaneous) randomized evaluations of experimental interventions, with potential for increased recruitment, comparability and long-term outcomes as a standard. This design will speed up the process of translating treatment innovations to the daily clinic.

The aim of this study is to collect data from different centres to obtain a larger case series and enable a better definition of the outcomes after pancreatic metastasectomy from primary colorectal cancer. To evaluate the possible benefits of surgery, we intend to retrospectively analyze the outcome of patients in whom pancreatic metastases have been surgically treated. Primary objective; To evaluate feasibility and safety of pancreas resection in metastatic colorectal cancer To evaluate oncological outcome at six months from surgical procedure Secondary objective: 1. To evaluate oncological outcome at 12 months from surgical procedure

In this study, the Quintuple method was applied for early intervention of prehepatic CTC-positive bowel cancer patients without dominant liver metastasis, aiming to explore the blocking effect of the Quintuple method on the metachronous liver metastases of colorectal cancer. A one-arm randomized clinical trial was conducted, and the patients were grouped according to their treatment methods. The patients with metachronous liver metastases were used as the end point of the experiment to evaluate the blocking effect of quintuple therapy.

This clinical trial aims to assess whether the addition of bevacizumab to atezolizumab and chemotherapy can improve response to treatment and progression-free survival in patients with extensive-stage small cell lung cancer (ES-SCLC) with liver metastases. The main questions it aims to answer are: In patients with ES-SCLC with liver metastases, can bevacizumab in combination with atezolizumab and chemotherapy prolong the length of time that the cancer does not progress? Is bevacizumab safe and tolerable when combined with atezolizumab and chemotherapy in patients with ES-SCLC and liver metastases? The study treatment includes two phases: Induction phase: bevacizumab will be administered in combination with atezolizumab and chemotherapy on a 21-day cycle for four cycles. Maintenance: atezolizumab and bevacizumab will be administered every 21 days for up to 12 months, or until unacceptable toxicity or disease progression. Participants will undergo blood tests every 3 weeks and tumor assessments every 6 weeks.

Vertebral metastases are events that affect the quality of life of tumor patients, and are often accompanied by severe pain at the site of metastasis and even by the risk of compression fracture. For vertebral metastases who are not yet at risk of vertebral instability fracture, a moderate dose (30Gy/10F) external radiation therapy is the most widely used treatment technique. Previous studies have shown that 60-80% of patients could achieve pain relief with moderate doses of radiation therapy, with median pain control duration of approximately 4 months. Stereotactic Radiation Therapy (SBRT) is currently the most advanced radiation therapy technique. This project proposes to treat vertebral metastases from non-small cell lung cancer using SBRT technology on the True Beam radiotherapy system to compare its efficacy with conventional external irradiation technology in terms of pain relief as well as local control.
