Filter by:acute myeloid leukemia (AML) is a malignant tumor of the hematopoietic system with high heterogeneity in cytogenetics and molecular biology.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is still the primary treatment option for patients with AML and the most effective method for radical treatment of AML.Despite considerable progress in allo-HSCT over the past decade, 30%-40% of patients still relapse, and post-transplant relapse remains the leading cause of death in patients with AML.
The purpose of this study is to study the performance of MRD monitoring in predicting the efficacy and prognosis of neoadjuvant therapy in patients with rectal cancer, and to explore the value of MRD detection in evaluating the prognosis of patients. In this prospective study, 50 patients with stage II-III rectal cancer who are planing to receive neoadjuvant chemoradiotherapy will be enrolled. The tumor tissue will be collected by colonoscopy before treatment and blood samples will be collected before treatment and during treatment.The whole blood samples will receive MRD detection. The change rate and clearance rate of MRD during treatment will be calculated, and will be associated with imaging efficacy evaluation, pathological efficacy evaluation,and prognosis, to determine the performance of MRD in predicting and judging the efficacy of neoadjuvant chemoradiotherapy and postoperative recurrence of rectal cancer.
In this project, the investigators intend to start a prospective registry for patients with newly diagnosed Philadelphia-negative ALL from 16 years old and above in participating centers, provided that all patients will be treated with the same regimen (a pediatric regimen BFM-based incorporating peg-asparaginase). All diagnostic/follow-up (after induction and consolidation blocks) samples will be centrally biobanked at Instituto do Cancer do Estado de Sao Paulo. The main goal of this study is to examine whether the implementation of a pediatric protocol under a prospective registry can increase event-free survival (EFS) and overall survival (OS) of newly diagnosed patients in the participating centers.
Evaluation of impact of use of 3D ultrasound in brain tumor surgery on extend of resection. Benefit for surgery, neurological outcome, accuracy and image quality are secondary outcome parameters. Control group is a retrospective matched pair cohort.
This trial aims to assess changes in minimal residual disease (MRD) status before and after radical concurrent chemoradiotherapy combined with immunotherapy and adjuvant immunotherapy after neoadjuvant immunochemotherapy in patients with inoperable stage II-III esophageal squamous cell cancer (ESCC), and correlate with the efficacy of adjuvant immunotherapy.
This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies
This is a single-center, single-arm, phase II study that will enroll multiple myeloma (MM) patients with persistent bone marrow minimal residual disease (MRD) post autologous stem cell transplant (ASCT) irrespective of the International Myeloma Working Group (IMWG) response.
To test the feasibility of collecting cell-free DNA (cfDNA) samples from DLBCL patients before and after treatment. cfDNA is DNA traveling in your blood outside of a cell and is easily collected from blood samples drawn using the vein puncture method.
This is an open-label, Phase I study of QN-030a (allogeneic NK cell therapy) in Acute Myeloid Leukemia Minimal Residual Disease(AML MRD). This clinical study is to evaluate the safety, tolerability and preliminary efficacy of QN-020a in patients with AML MRD, where a "3+3" enrollment schema will be utilized at dose escalation stage. Up to 18 patients will be enrolled.
In our study, the ultra-deep sequencing of circulating tumor DNA (ctDNA) and urine tumor DNA (utDNA) were performed to assess whether ctDNA and utDNA can be used as predictive biomarkers for the detection of minimal residual disease (MRD) and early diagnosis of UTUC recurrence, and explored the role of ctDNA and utDNA detection of MRD in the prediction of adjuvant therapy efficacy and prognostic evaluation.
