Study summary

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.

Study population

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Female aged 18 years or older.
  2. confirmed cervical cancer, including squamous cell carcinoma, adenocarcinoma, and other subtypes.
  3. Planned to receive radical treatment, including surgery, radiotherapy, or chemotherapy.
  4. Voluntarily agrees to participate and signs the form.
  5. Able to provide complete clinical and follow-up information for the study.

Exclusion criteria

Exclusion Criteria:

  1. A history of other (except cured tumors such as basal cell carcinoma of the skin).
  2. Severe hepatic or renal insufficiency, coagulation disorders, or active infection.
  3. Pregnancy or breastfeeding.
  4. Inability to cooperate with follow-up or sample collection.
  5. Prior systemic therapy for cervical cancer (except therapy).
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Interventions

  • OtherLow-depth cfDNA fragmentomics testing

    Observational study; no therapeutic intervention. Study procedures include serial peripheral blood collection (10 mL per time point) before initial treatment, 1-4 weeks after standardized treatment, at 3 and 6 months, then every 3 months until 2 years after treatment or an endpoint event, and collection of fresh or paraffin-embedded tumor tissue. Samples will undergo low-depth cfDNA fragmentomics analysis (tumor fraction, fragment length distribution, copy number variation), cfHPV-DNA testing, whole-exome sequencing, and multi-omics analysis. Routine clinical treatment is unchanged. The main research-related risk is blood draw-related discomfort, bleeding, or bruising.

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2026 (actual). Primary completion is estimated for Oct 2027, 21 months after the start.

Of 189 non-industry observational studies under Uterine Cervical Neoplasms, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 158. This study's planned 21 months is below that.

Counting every sponsor, half of 213 studies reached it within 58 months; a quarter within 28 and three quarters within 158.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
