Use of cfDNA in Monitoring and Guiding Treatment for Cervical Cancer
A Prospective Study on the Application of Low-Depth Circulating Free DNA Fragmentomics in Monitoring Recurrence and Guiding Therapy for Cervical Cancer
This is a prospective, single-center, observational cohort study that plans to enroll 100 women aged 18 years or older with histologically confirmed cervical cancer who are scheduled to receive radical surgery, radiotherapy, or systemic therapy. The study aims to establish and validate a low-depth cfDNA fragmentomics approach-including tumor fraction, fragment length distribution, and copy number variation-together with cfHPV-DNA testing for monitoring recurrence risk and predicting treatment response. Serial blood samples (10 mL per collection) will be obtained before initial treatment, 1-4 weeks after standardized treatment, at 3 and 6 months, and every 3 months thereafter until 2 years after treatment completion or until an endpoint event; fresh or paraffin-embedded tumor tissue will also be collected for whole-exome sequencing and multi-omics analysis. The study will not alter participants' routine clinical treatment. Research-related risks are mainly blood draw-related discomfort, bleeding, or bruising; risks from standard radiotherapy, chemotherapy, or immunotherapy are part of routine clinical care and are not introduced by this observational study. Privacy and confidentiality risks will be minimized through informed consent, secure data storage, restricted database access, and confidential handling of records. cfDNA testing will be provided free of charge, and appropriate compensation may be provided based on participation and time commitment. The study is funded by 3D Medicines (Shanghai) Co., Ltd.; conflict-of-interest, data/sample-sharing, and intellectual property arrangements will be disclosed and managed according to institutional requirements.

調査対象母集団
This single-center prospective observational cohort will enroll 100 adult women aged ≥18 years with histologically confirmed cervical cancer (including squamous cell carcinoma, adenocarcinoma, and other subtypes) who are planned to receive radical treatment with surgery, radiotherapy, and/or systemic therapy and who can provide complete clinical and follow-up data. Participants will undergo serial blood and tumor tissue collection before and after standard treatment for low-depth cfDNA fragmentomics and cfHPV-DNA analysis. Patients with a history of other malignancies (except cured skin basal cell carcinoma), severe hepatic/renal insufficiency, coagulation disorders, active infection, pregnancy or breastfeeding, inability to cooperate with follow-up or sample collection, or prior systemic therapy for cervical cancer (except neoadjuvant therapy) will be excluded. Routine clinical treatment is not altered.
