A Prospective, Single Center Clinical Study on the Clinical Significance of Personalized ctDNA-MRD in Predicting the Efficacy and Monitoring the Risk of Recurrence of Cervical Cancer
This study plans to enroll 80 patients with locally advanced cervical cancer (stage IB-ⅣA) confirmed by histology or cytology (according to the 2018 FIGO staging standard), who are expected to receive surgical resection or curative radiotherapy and chemotherapy. Collect baseline tumor tissue samples from patients during the treatment period, as well as peripheral blood samples (20 ml/time) from multiple treatment timepoints. Mutations in tumor tissue were detected by the 1021 genes panel, then personalized MRD monitoring probes were customized for patients, allowing for multi node peripheral blood sample ctDNA detection of enrolled patients. The clinical significance of ctDNA in prognostic stratification, recurrence monitoring, and efficacy prediction in surgical/non-surgical cervical cancer patients was explored. And compare the consistency and differences between ctDNA detection technology, imaging, and blood tumor markers in monitoring tumor disease progression, and evaluate the correlation between ctDNA status after curative treatment and patient PFS and RFS.
A Phase 2, Open-label, Single Arm Study of Combined HAIC, Lenvatinib and Pucotenlimab as Conversion Therapy for Unresectable Intrahepatic Cholangiocarcinoma
This is an open-label, single-arm, phase 2 study. The purpose of study is to evaluate the feasibility and safety of hepatic artery infusion chemotherapy combined with lenvatinib and pucotenlimab as conversion therapy for unresectable intrahepatic cholangiocarcinoma.
Exploring the Potential of ctDNA-MRD for Recurrence Surveillance and Prognostic Evaluation in High-risk Endometrial Cancer
Patients with high-risk endometrial cancer may have MRD after surgical treatment, which is a potential source of follow-up early recurrence and metastasis, and because of its limited resolution, traditional imaging (including PET/CT) or laboratory methods may not be reliable to detect. For patients with radical treatment, the uncured population can be identified by the detection of MRD, suggesting that patients may benefit from further intervention. The purpose of this study is to explore the prognostic value and recurrence monitoring value of ctDNA-MRD in patients with endometrial carcinoma.
