View clinical trials related to Minimal Residual Disease.
Filter by:Chronic lymphocytic leukaemia (CLL) is the most common adult blood cancer in the United Kingdom. CLL means that many cancer cells appear in the blood, bone marrow and other tissues, for example, the spleen where some blood cells reside. Most patients with CLL have been diagnosed by chance, have no symptoms as a result of CLL, and do not need urgent treatment. However, when the cancer cells build up, people experience symptoms of CLL, and treatment is required. One of the current treatments for CLL is chemo-immunotherapy, that targets and kills cancer cells in the blood. However, this treatment does not kill all cancer cells. Some cancer cells survive by 'hiding' in the bone marrow and tissues, like the spleen, where the treatment cannot get to, this is called minimal residual disease (MRD). MRD eventually builds up and patients experience symptoms of CLL again. New approaches to detect and treat MRD are needed. Research has shown, that the number of blood cells, increases after exercise and that many of these blood cells come from the bone marrow and other tissues. This study will investigate if exercise can move CLL cancer cells that are 'hiding' in the bone marrow and other tissues into the blood, thus improving the detection of MRD. By moving cancer cells into blood, the investigators also think this will improve the way chemo-immunotherapy works. In this study, the investigators will investigate the number of cancer and natural killer (NK) cells in the blood after exercise, in three different groups of people with CLL: before treatment; during treatment; and after treatment has finished.
MDS/AML with MRD and impending relapse after allogeneic stem cell transplantation and/or conventional chemotherapy
This phase I/II trial studies the side effects and best dose of donor lymphocyte infusions when given together with daratumumab and to see how well they work in treating participants with acute myeloid leukemia that has come back after a stem cell transplant. A donor lymphocyte infusion is a type of therapy in which lymphocytes (white blood cells) from the blood of a donor are given to a participant who has already received a stem cell transplant from the same donor. The donor lymphocytes may kill remaining cancer cells. Monoclonal antibodies, such as daratumumab, may interfere with the ability of cancer cells to grow and spread. Giving daratumumab and donor white blood cells may work better in treating participants with acute myeloid leukemia.
This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
Cryopreservation of ovarian tissue is offered to young girls and women aged under 35 who have to undergo sterilizing gonadotoxic treatment, with the aim of preserving their fertility. The main part of the ovary is preserved, as primordial and primary follicles are resistant to freezing / thawing protocols. In the absence of other techniques (in vivo maturation, injecting isolated ovarian follicles, etc.) autografting this cryopreserved tissue is currently the only technique allowing fertility to be restored. Autograft is possible only if the indication for ovary cryopreservation is a non-neoplastic pathology or a malignant pathology with a low risk of ovarian metastasis. In other cases of neoplastic pathologies, particularly in cases of acute leukemia, tissue cannot as yet be re-used due to the lack of any codified technique for evaluating residual disease (MRD). The team has for two years been developing and validating a technique to look for residual disease in fragments of ovarian cortex in cases of acute leukemia. This technique is based on an original protocol for dissociating ovarian tissue to obtain a population of isolated ovarian cells that may be analyzed by multicolor flow cytometry. The specificity and sensitivity of the technique have been demonstrated in an experimental model. This model consists in using 8 color flow cytometry to look for characterizable leukemia cells added in different dilutions to a population of isolated ovarian cells taken from model ovarian cortex and up to a dilution of 10-5. When the molecular markers were present on diagnosis, they were found by Real-Time Quantitative Polymerase Chain Reaction (RQ-PCR) with the same dilutions. The model tissue came from laparoscopic ovarian drilling in patients with polycystic ovary syndrome. The main objective of this project is to validate techniques that have been previously codified with different populations of leukemia cells that may be characterized. The investigators then aim to adapt and validate this technique to look for MRD using 8 color flow cytometry on cryopreserved fragments of ovarian cortex from leukemia patients that are at risk of metastasis. Secondary objectives will be to implement procedures for oncological qualification of grafts in cases of malignant pathology and to consider the recommendations for using this cryopreserved ovarian tissue through the autograft technique for these indications.
Acute myeloid leukemia(AML) patients with favorable and intermediate cytogenetics at diagnosis are generally excluded from first-line allo-SCT. However, these patients may eventually relapse in some cases. Our previous study found that stratification of treatment based on cytogenetics and therapeutic response could benefit low and intermediate AML. To further verify the results, we conducted a prospective multi-center study. The purpose of this study is to establish risk stratification based on cytogenetics and minimal-residual-disease (MRD) analysis to determine whether a MRD-directed therapy for low and intermediate AML patients has positive results in terms of overall survival.
Study purpose is to assess the prognostic role of Minimal Residual Disease (defined as medullary expression of WT1 gene), performed at Baseline and during treatment according to clinical practice. MRD results will be relate to treatment outcome and survival analysis variables (Overall Survival, Disease Free Survival, Cumulative Incidence of Relapse)
Allogeneic hematopoietic cell transplantation (Allo-HSCT) is an effective therapy for acute leukemia, but relapse remains an important problem. Therapy options for relapse include stopping immune suppression, re-induction of chemotherapy, donor lymphocyte infusion (DLI), and another transplantation used alone or in combination. However, the efficacy of these interventions is limited. One approach to the relapse problem is to intervene before hematologic or pathologic relapse occurs based on minimal residual disease (MRD). In this study, the efficacy of MRD-directed DLI on transplantation outcomes will be evaluated in patients with acute leukemia receiving allo-HSCT.
This phase I clinical trial studies the side effects and best dose of CD19-specific T-cells in treating patients with lymphoid malignancies that have spread to other places in the body and usually cannot be cured or controlled with treatment. Sometimes researchers change the deoxyribonucleic acid (DNA) (genetic material in cells) of donated T-cells (white blood cells that support the immune system) using a process called "gene transfer." Gene transfer involves drawing blood from the patient, and then separating out the T-cells using a machine. Researchers then perform a gene transfer to change the T-cells' DNA, and then inject the changed T-cells into the body of the patient. Injecting modified T-cells made from the patient may help attack cancer cells in patients with advanced B-cell lymphoma or leukemia.
The aim of this study is to compare the effects of three types of perioperative analgesia on the number of circulating cancer cells (representing minimal residual disease) following radical colon cancer surgery. Patients will be randomized into one of three groups. The intervention group will receive combined regional and general anesthesia during surgery and postoperative epidural analgesia. The two control groups will receive balanced general anesthesia and either morphine-based or piritramide-based postoperative analgesia. We hypothesize that epidural analgesia will be favorable to both piritramide-based and morphine-based analgesia and that piritramide-based analgesia will be favorable to morphine-based analgesia with regard to the number of circulating cancer cells and its development in the early postoperative period.
