Filter by: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.
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 project is focusing on who have locally advanced esophageal squamous cell carcinoma and have undergone neoadjuvant and adjuvant therapy, followed by surgical resection. The exclusive MRD (Minimal residual disease) probe consists of an exclusive "molecular label" formulated according to the individual genome mutation profile and 21 critical tumor driver genes. By continuously monitoring each patient's ctDNA dynamics, changes in ctDNA concentration or ctDNA-MRD negative/positive results will serve as the primary indicators to assess the efficacy and prognosis of patients with esophageal squamous cell carcinoma.
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
Hematopoietic stem cell transplantation (HSCT) is the effective and even the only cure treatment option for ph+ acute lymphocyte leukemia (ph+ALL). However, the outcome has been insufficient and relapse remains the major cause of treatment failure and poor survival, especially for patients with persistent minimal residual disease (MRD). It is believed that clearance of MRD pre-HSCT could significantly reduce the incidence of relapse post-HSCT. Olverembatinib has been documented as a promising third generation of TKIs. Meanwhile, Inotuzumab ozogamicin (InO) , an antibody-drug conjugate approved in the US and the European Union, has been applied in relapsed/refractory acute lymphoblastic leukemia (R/R ALL) and achieved good treatment outcome. This prospective, single arm and multicenter study is to investigate the efficacy and safety of combination of Olverembatinib and Ino for MRD clearance before bridging to HSCT.
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.
To study the efficacy of sintilimab combined with anlotinib for perioperative non-small cell lung cancer. To explore the clearance effect of sintilimab combined with anlotinib for postoperative adjuvant therapy based on evaluating minimal residual disease.
The purpose of this study is to see whether receiving local ablative therapy (LAT) when minimal residual disease/MRD levels are rising can reduce MRD levels and control metastatic non-small cell lung cancer/NSCLC longer compared to systemic therapy.
So far, MRD assessment by liquid biopsy (ctDNA) has not been used to predict postoperative treatment efficacy and recurrence risk of GIST patients because of special disease characteristics and technological limitations. Therefore, we conducted this prospective multi-center, single-arm observational study to collect 45 operable patients with locally advanced, suspected high-risk GIST. NGS genetic testing platform is used to detect tumour tissues and peripheral ctDNA will also be dectected. we try to explore the correlation between PFS/OS and MRD in high-risk GIST patients by analyzing the relationship between dynamic changes in ctDNA mutation spectrum and postoperative adjuvant therapy efficacy, and to evaluate MRD-based genomic characteristics to guide further treatment.
