Active clinical trials for "Neoplasm Metastasis"

This study is a multicentre, prospective, randomised trial, aims to evaluate the efficacy and safety of Irinotecan Drug-Eluting Beads combined with regorafenib as the third-line treatment for a patient with colorectal cancer liver metastases. The study is planned to enrolled 126 patients failing first- and second-line standard chemotherapy treatment.

The primary objective is to demonstrate superiority of neoadjuvant systemic therapy followed by repeat local treatment as compared to upfront repeat local treatment in patients with at least one locally treatable recurrent CRLM in the absence of extrahepatic disease.

The goal of this clinical trial is to learn about hepatectomy on the prognosis of patients with nasopharyngeal carcinoma liver metastases (NCLM). The main questions it aims to answer are: To explore the effect of hepatectomy on the overall survival, recurrence-free survival and other prognostic indicators of patients with NCLM. To explore the impact of hepatectomy on the safety of patients with NCLM. Researchers will compare the prognosis of the patients in the hepatectomy group and the patients with NCLM who were prospectively enrolled in the same institution and received only systemic treatment at the same time by propensity score matching.

Multicentric randomised trial. The goal of this clinical research study is to evaluate the efficacy and safety of serplulimab combined with FOLFIRI+bevacizumab in the treatment of pMMR/Ras/BRAF wild-type unresectable peritoneal metastasis of colon cancer.

This clinical trial is aimed at the evaluation of the safety and clinical activity of tiragolumab in combination with carboplatin, pemetrexed and atezolizumab in the first line treatment of metastatic non-squamous NSCLC patients with asymptomatic untreated brain metastases.

A Phase 1/2 Open-label, Multi-center Study of the Safety, Pharmacokinetics, and Anti-tumor Activity of LYT-200 Alone and in Combination with Chemotherapy or Tislelizumab in Patients with Metastatic Solid Tumors

The treatment proposed in this trial is to administer intra-arterial chemotherapy to liver metastases from colorectal cancer when the blood flow to and from the liver has been isolated via balloon catheters through a vascular access system called the AVAS. The objective of this study is to evaluate the tumour response of repeated and isolated intra-arterial liver isolation oxaliplatin compared with the standard systemic chemotherapy (intravenous 5-FU + leucovorin + oxaliplatin [FOLFOX] or oral capecitabine with IV oxaliplatin [XELOX]).

Brain metastases are the most common brain tumors in adults. It is estimated that around 10-30% of cancer patients would develop brain metastases during the course of their illness. Whole brain radiotherapy (WBRT) is the treatment of choice for the majority of patients with brain metastases. WBRT yields high radiologic response rate (27~56%) and is effective in rapid palliation of neurologic symptoms as well as prolongs time to neurocognitive function decline caused by intracranial lesions. By using conventional fractionation, more than one- third of patients developed late neurocognitive toxicity while memory impairment was the most common symptom. The incidence is even higher when a formal and sensitive neurocognitive assessment was prospectively evaluated. With more long-term survivors nowadays, it has become increasingly important to minimize neurocognitive function decline and maintain quality of life in patients with brain metastasis. The function of hippocampus is cooperation in learning, consolidation and retrieval of information and essential for formation of new memories. Bilateral and unilateral radiation injury of the hippocampus is known to alter learning and memory formation. Several preclinical studies support the hypothesis of hippocampus-mediated cognitive dysfunction by ionizing radiation. Clinical studies show increase in radiation dose to hippocampus is associated with subsequent neurocognitive function impairment in adult and pediatric patients. Furthermore, the result of phase III randomized trials suggested hippocampal avoidance plus Memantine significantly reduce the risk of neurocognitive impairment at 6 months from 68.2% in control arm with standard WBRT to 59.5% in experimental arm. In the investigator's prior investigation, patients received conformal WBRT with bilateral hippocampal avoidance also had significant less declines in verbal memory at 6 months. Previous studies showed the right and left hippocampus exert different neurocognitive functions. Several retrospective studies also demonstrated that the radiation dose to the left hippocampus is more related to neurocognitive impairment. Planning study and investigation showed that by avoiding the left hippocampus alone, the radiation dose to the spared unilateral hippocampus is further decreased. In present study, a single blind randomized phase II trial is designed to investigate the effectiveness of neurocognitive function preservation using conformal WBRT with bilateral or unilateral hippocampal avoidance and memantine.

The purpose of this study is to determine if performing radiotherapy (SRS) prior to surgery results in better treatment outcomes than performing surgery before radiotherapy for patients with brain metastases. Brain metastases occur when cancer cells from a primary cancer (e.g. lung, breast, colon) travel through the bloodstream and spread (metastasize) to the brain. As these new tumors grow they apply pressure and change how healthy brain tissue works. This can lead to a loss of brain function and worsening quality of life. Treatments for patients whose cancer has spread to the brain is often surgery, radiation therapy (radiotherapy) or a combination of both. Surgery is one the main treatments for brain tumors. To remove the tumor, a neurosurgeon makes an opening in the skull and attempts to the remove the entire tumor. If the tumor is too close to important brain tissue, the surgeon may attempt to remove part of the tumor. Removal of the tumor from the brain tissue is called resection. The complete or partial removal of tumor helps to relieve symptoms by reducing pressure on healthy tissues and reduces the amount of tumor that needs to be treated by radiotherapy. One type of radiotherapy used to treat brain metastases is stereotactic radiosurgery (SRS). SRS uses many focused radiation beams to treat tumors within the brain. Unlike surgery, there is no incision or cut being made. Instead, SRS uses an accurate map of your brain to deliver a precise beam of radiation to the tumors. The radiation damages the tumor cells forcing them to shrink and die off. The focused radiation beams also limit damage to healthy brain tissue minimizing side effects. Surgery followed by radiotherapy is a standard treatment for brain metastases. However, there are still risks associated with the combination of treatments. This study plans to investigate whether performing surgery prior to SRS results in improved quality of life and decreased side effects.

This study evaluates the addition of stereotactic radiosurgery (SRS) to the combination of binimetinib + encorafenib + pembrolizumab in the treatment of BRAFⱽ⁶⁰⁰ mutation-positive melanoma with brain metastases (MBM).
