Filter by:The goal of this observational study is to compare the efficacy and safety of autologous hematopoietic stem-cell transplantation (ASCT) versus non ASCT regimens in primary multiple myeloma patients achieved MRD negativity after induction. The main question it aims to answer is: In primary multiple myeloma patients who achieved MRD negativity after induction, non ASCT regimens are not inferior to ASCT or not? Participants will receive ASCT or non ASCT regimen according to their own choice. Researchers will compare ASCT and non ASCT group see if any significant difference in efficacy and safety.
The goal of this study is to evaluate sustained MRD negativity for one year in DKRD induction & consolidation therapy +/- ASCT in newly diagnosed high-risk multiple myeloma patients. It aims to evaluate the efficacy and safety of the combination regimen of Daratumumab in combination with carfilzomib, lenalidomide, and dexamethasone (DKRD) +/- ASCT for the treatment of patients with newly diagnosed high-risk multiple myeloma. Participants will receive bortezomib based induction therapy for one cycle, and then DKRD induction for 3 cycles(+ASCT), DKRD consolidation for 2-4 cycles, and DKR maintenance treatment(adjusted according to MRD negativity after consolidation therapy)
Evaluating the value of dynamic monitoring of a colorectal cancer liver metastasis cohort underwent curative resection after receiving multipoint ctDNA detecting in predicting recurrence prognosis and guiding adjuvant chemotherapy treatment.
The CORRECT - MRD I study will prospectively enroll patients who have undergone complete surgical resection for stage II or III colorectal cancer. Patients will be followed for up to 5 years for recurrence.
To find the highest and/or recommended dose of TROP2-CAR-NK cells combined with cetuximab in participants with MRD CRC.
This is a Phase 2 study, open-label, 2-cohort, multicenter, national, interventional in patients with newly diagnosed multiple myeloma. The study will investigate teclistamab (Tec) in combination with lenalidomide (Len) (Tec-Len; Cohort A) or in combination with talquetamab (Tal) (Tec-Tal; Cohort B), allocated based on minimal residual disease (MRD) status (MRD [-] [standard-risk] vs MRD [+] [high-risk] respectively). The patient population will consist of adults men and women at least 18 years to younger than 66 years of age, who meet eligibility criteria.
This study plans to conduct ctDNA testing on EGFR mutation-positive stage II-IIIA (N1-N2) NSCLC patients after radical surgery (R0 resection). Patients with positive ctDNA testing will receive standard treatment according to clinical guidelines, while patients with negative ctDNA testing will be assessed based on comprehensive clinical and pathological characteristics. After receiving or not receiving standard adjuvant chemotherapy, patients will be randomly assigned in a 1:1 ratio to either the observation follow-up group (experimental group) or the osimertinib adjuvant treatment group (control group). The aim is to explore whether observation follow-up for patients with negative ctDNA after surgery has a prognosis non-inferior to osimertinib treatment, and to investigate the disease-free survival rate of EGFR mutation-positive stage II-IIIA (N1-N2) NSCLC patients with positive ctDNA after surgery receiving osimertinib adjuvant treatment, providing more precise treatment guidance for adjuvant therapy in this specific type of NSCLC patients with EGFR mutation-positive tumors.
The presence of minimal residual disease (MRD) is an important prognostic factor for multiple myeloma, while copy number variation (CNV) is a widely accepted biomarker used for multiple myeloma (MM). Detecting MRD and monitoring clonal evolution by monitoring CNV using low-pass whole genome sequencing is promising due to its high analytical sensitivity. To evaluate the correlation between MRD detected by flow cytometry and low-pass whole genome sequencing, nearly 200 samples were collected for this study. We applied ultrasensitive chromosomal aberrations detection to detect CNV for each patient. The follow-up samples were then collected and sequencing used the same method.
Improving personalized cancer treatments and finding the best strategies to treat each patient relies on using new diagnostic technologies. Currently, for colorectal cancer, the methods used to decide who gets additional post-surgery treatment are suboptimal. Some patients get too much treatment, while others do not get enough. There is a new way to explore if there is any cancer left in a patient's body using circulating tumor DNA (ctDNA) detected in blood samples. This can help decide who needs more treatment after surgery. Even though many tests have been developed, it has yet to be determined which test performs best at relevant time points. The GUIDE.MRD consortium is a group of experts, including scientists, technology, and pharmaceutical companies. The consortium is working on creating a reliable standard for the ctDNA tests, validating their clinical utility, and collecting data to help decide on the best treatment for each patient. FRENCH-MRD-CRC is the French study of the european GUIDE.MRD project.
The overall objective of this GUIDE.MRD consortium is to confirm that ctDNA detected after curative intended treatment for PDAC is a marker of residual disease and for risk-of-recurrence, and applicable in clinical practice. Primary objective To confirm that ctDNA analyses performed after PDAC treatment can identify patients with a high risk-of-recurrence. Specifically, the investigators want to determine the association between disease-free survival (DFS) and ctDNA detection status after 1. curative-intended surgery and 2. adjuvant chemotherapy.
