Active clinical trials for "Neoplasm Metastasis"

The use of intraoperative ultrasound (IOUS) allows us to perform new conservative hepatectomies. The investigators previously reported the systematic subsegmentectomy by IOUS-guided finger compression for segments 2-3, which is currently applied for patients with hepatocellular carcinoma (HCC)on cirrhosis. The investigators herein describe a novel technique, which consists in the systematic right posterior sectionectomy by IOUS-guided finger compression.

Title of the study A study to examine the value of broad agnostic NGS panel testing versus reimbursed organ-directed NGS: a Belgian Precision study of the BSMO in collaboration with the Cancer Centre Study Number BSMO 2020-1 Study Phase Exploratory Sponsor Belgian Society of medical Oncology (BSMO) Treatment None Background and Rationale Several drugs targeting mutated gene products in cancer cells are available to Belgian patients through reimbursement of the drugs and, soon, by reimbursed organ-specific genomic testing. This context is unfavorable with regard to the following issues: Many more additional drugs with sound scientific rationale and preclinical evidence are available through clinical trials. The relevant genes are generally not included in the reimbursed NGS and ad hoc identification of such patients is extremely difficult and thus severely hampering the accrual in such trials. This denies patients a potential access to innovative treatments from which they could benefit and hampers progress. The same genes can be mutated in other cancer types, other than the reimbursed context, but are not detected due to the organ-specific approach in reimbursed NGS. Examination of these genes with an agnostic approach would give these other patients potential access to the drugs (via various routes, including clinical trials or medical need or otherwise) The broader panels applied by some Belgian platforms (50-100 genes), sometimes in an agnostic approach, do not cover all potentially actionable genes or not all types of actionable variants in these genes. Rearrangements which are highly actionable are not systematically covered in NGS testing, but rely on immunohistochemistry (if done at all) of fusion panels testing that requires additional funding. The various Belgian NGS labs use accredited but heterogeneous methodology and it has been reported that the detection rate of some mutations varies from one site to another. Therefore, from a patient and oncologist point of view there are current deficiencies that jeopardize optimal access of patients to current or novel genome-driven therapies. Defective identification of sensitive patients limits the implementation of clinical trials and their accrual rates and therefore the attractiveness of Belgium for such trials. There are more comprehensive commercial platforms that cover a large set of actionable genes (up to hundreds of genes) and the various types of mutations in these genes: sequence mutations, rearrangements, resulting in fusion genes, and gene amplifications. These commercial vendors have adequate comprehensive methodology but are too expensive (at their current public pricing) for general application. One of these is the platform of Foundation Medicine that builds on a large experience in variant annotation in the US and includes probably all current actionable targets including gene mutations, fusions, MSI, and TMB, all at once in one result. They also report actionability and established or clinical trial treatment options. To oncologists this is very attractive compared to the fragmented, sequential and very limited current reimbursed conditions. The investigators estimate that up to 20% of advanced cancer patients could get access to genotype-based treatment that are not covered by the organ-based reimbursement based access to NGS. This can be in the form of off-label application of reimbursed drugs, pharma-sponsored drug development trials that address a specific genotype or pharma sponsored or academic basket trials. Without broad agnostic testing the identification of eligible patients remains extremely difficult. A recent study [A study of genetic characteristics and suitability for targeted cancer treatment (TARGET)] showed that the rate of detection of actionable mutations increased from 28% with local testing to 66% with Foundation Medicine testing. Objectives To determine the added value of comprehensive and agnostic NGS versus "real-world" practice ("real-world" practice means local testing, no reimbursement for local testing and/or no accessible metastatic lesion) in providing patients with advanced/metastatic solid tumors access molecular guided therapy and/or immunotherapy based on genomic results. To describe the landscape of genomic alterations detected by reimbursed NGS To describe he landscape of genomic alterations detected by comprehensive panel testing To assess the technical success of comprehensive panel testing To describe the uptake of treatments recommended by the molecular tumor board guided by the genomic testing.

The CoNoR study aims to assess whether the use of the LiMAx test and the HepaT1ca pre-operative planning magnetic resonance scan impact upon technical resectability decision-making in colorectal liver metastases (CLM).

Colorectal cancer screening showed an increased incidence of malignant colorectal polyps pT1 after endoscopic excision. Their management is not yet standardized, for the presence of histological features increasing early lymph node involvement. The literature has proposed several histopathological criteria, for which the risk of lymph node metastasis can vary (6-20%), but final data are not yet available. Aim 1.To collect data about patients undergoing an endoscopic polypectomy with histologic finding of pT1, retrospectively and prospectively, dividing both databases into two groups, endoscopic group (EG) and surgical group (SG) Aim 2. To analyze retrospectively which pathological criteria can increase the risk of lymph node metastasis and to elaborate a prognostic score for lymph node metastatic risk Aim 3. To verify prospectively the prognostic score capacity on predicting lymph node metastasis Aim 4. To calculate the disease free survival, overall survival, local recurrence rate and distal recurrence rate and verify if there is a difference between EG and SG According to literature, the most important histopathological criteria to establish the high risk of lymph node metastasis are: Lateral margin of healthy tissue (high risk: <1mm and piecemeal polypectomy) Depth of submucosa invasion (high risk: >1000 μM or sm2-sm3 for sessile polyps; Haggitt level 4 for pedunculated polyps) Vascular invasion (high risk: presence) Lymphatic invasion (high risk: presence) Tumor budding (high risk: presence) Tumor differentiation (high risk: grade G3-G4 or mucinous) A database will be used by all participating centres for collecting clinical and pathological data. All the analyses will be centralized by the PI. Uni-multivariate analyses will be conducted at the end of data collection for retrospective arm and at 2 years of follow-up for prospective arm. Impact: This study aimed to investigate pathological risk factors for lymph node metastasis in pT1 colorectal polyps after endoscopic polypectomy; their accurate identification could lead to improve their management, avoiding useless complementary surgery. Results could change clinical practice and reduce health-related costs.

The investigators seek to perform an observational study in patients with brain metastases that are to undergo whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) treatment in order to quantify any baseline neurocognitive changes which may result from intracranial disease burden, from radiation treatment (WBRT or SRS), or both. To do so, the investigators will compare matched control subjects to patients at time points obtained before and after radiation treatment with either SRS or WBRT. Pre-treatment evaluation will include neurocognitive testing and an assessment of fMRI task-related activation patterns and resting state brain activity. Four and twelve month post-treatment neuropsychological evaluations will be performed and pre- and 4-month post-treatment fMRI scans will be obtained in order to evaluate changes in neurocognitive functioning with a focus on short-term memory and executive function domains. A brief quality of life assessment will also be completed at each study time point. In order to plan treatment strategies in the future it is important to accurately document the effects of intracranial disease burden as well as radiation treatment on neurocognitive functioning, validate fMRI activation tasks for short term memory and executive functioning, and quantify the activation volumes that would potentially be spared in future "cognitive sparing" protocols. The investigators hypothesize first that the amount and location of intracranial disease burden will represent pre-treatment variables that affect NCF. The compromised NCF will be visualized in both the resting state and task-oriented neurocognitive exercise. The investigators anticipate that any perturbation in resting state caused by intracranial disease burden should be reflected in patients when compared to matched controls. The investigators hypothesize additionally that cancer patients with brain metastases undergoing radiation treatments will have improved intracranial disease control at the expense of executive and memory function with differences between patients that undergo stereotactic radiosurgery or whole brain radiation alone.

This study is to evaluate the effectiveness of 18F-FDG PET in following up of metastastic bone lesions and in predicting outcome for breast cancer patients after therapy. Primary outcome: Using 18F-FDG uptake to evaluate the metastatic bone status after treatment. The PET results will be compared with the results in Tc-99m MDP bone scintigraphy. Secondary outcome: Evaluate the relationship between the 18F-FDG uptake of the metastatic bone lesions and (1) breast cancer related tumor marker, (2) patients' survival.

Cancers are among the most frequent leading causes of death in Taiwan, and many of them show their respective unique epidemiological and pathophysiological features in Taiwanese population. One of the distinguishing features of cancers includes their potential to metastasize outside the primary tumor. Pleural cavity and peritoneum are two of the most frequent sites of metastases when serosal surfaces are involved. The prognoses of such patients are extremely poor with a median survival of months. The understandings of cancer biology of tumor metastasis demand more in-depth studies at the molecular and cell levels. Studies based on cell culture are excellent approaches for this purpose as the cell culture provides a relevant and renewable model for studying the pathological and molecular changes underlying human malignant tumors.

The aim of this study is to explore whether target therapy in combination with chemotherapy as treatment could improve survival or tumor response in patients undergoing Synchronic Hepatectomy for Colorectal Liver Metastases.

Liver resection is an operation to remove the diseased part of the liver. The liver is supplied by two vessels, the hepatic artery and the portal vein supplying 25% and 75% respectively of the total blood flow with 50% oxygen from each vessel. During liver resection it is standard practice to clamp both vessels(Pringle's manoeuvre), so as to avoid bleeding. Clamping both the vessels deprives the unaffected liver from nutrients required for survival. Reinstating the blood supply causes further damage by pouring harmful substances into the liver, which accumulate during the clamping. We hypothesize that not clamping the oxygen rich hepatic artery will cause less damage to the liver. Our aim is to compare the Pringle manoeuvre with portal vein clamping, to identify if the latter will result in less tissue injury and thereby fewer complications. Initially we aim to conduct a pilot study. The main objective is to ensure that patients can be successfully recruited and that data capture is complete. The secondary outcomes will be development of infective complications by 30 days following surgery, bleeding and blood transfusion requirements, heart/chest complications, recovery of liver functions, growth of remnant liver, death within 30 days following surgery, length of high dependency unit/hospital stay and quality of life at 3 months after surgery. There is published literature on the safety of this method and in the event of any intraoperative problems, the procedure will be converted to the standard Pringle manoeuvre. The Liver Unit at St James's University Hospital has four surgeons performing around 270 liver cancer resections per year, of which nearly 160 are for bowel cancer spread. Considering the team's experience in research and liver surgery, we believe it is well placed to conduct the trial in a safe and efficient manner.
