Study summary

The purpose of this study is to determine if ctHPVDNA (circulating tumor HPV DNA) can be used as a non-invasive biomarker for identification and treatment monitoring of cervical cancer by characterizing correlation between plasma ctHPVDNA, urine transrenal HPVDNA (TrHPVDNA) levels and presence of cervical cancer at diagnosis and following definitive intent management.

Read the detailed description

Early stage cervical cancer is managed surgically while chemoradiation is the mainstay for treatment of bulky or advanced stage disease. The primary aim of post-treatment surveillance is to detect early recurrences and guide additional therapy. There is no definitive agreement on the best practice for cervical cancer surveillance. Most recurrences are detected based on patient history and physical exam as there is limited data to support cervicovaginal cytology and routine use of imaging in follow up. Novel non-invasive biomarkers are needed to monitor disease status, detect early recurrence and guide personalized treatment decisions. Biospecimens including urine and blood plasma will be collected from patients presenting to the UNC Department of Gynecology Oncology and Multidisciplinary clinics with newly diagnosed cervical cancer to assess for HPVDNA. Archived or residual tissue will also be accessed. For patients who undergo definitive management with surgery or chemoradiation, a post-treatment blood plasma and urine sample will be collected 2-6 weeks after completion and will be compared to pre-therapy ctHPVDNA and TrHPVDNA levels.

Inclusion criteria

  • 18 years of age or older on day of signing
  • New diagnosis of cervical cancer
  • Subject is willing and able to comply with study procedures based on the judgement of the investigator or protocol designee

Exclusion criteria

Exclusion Criteria:

  • Women who are pregnant
Terms in these criteria, in plain language(1)

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.

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.

What researchers measure

Primary outcomes

  1. Relationship between ctHPVDNA levels in plasma, TrHPVDNA levels in urine, and presence of cervical cancer in women being evaluated in clinic.

    We will quantify ctHPVDNA levels in blood plasma and TrHPVDNA in urine from patients with cervical cancer at time of diagnosis.

    Time frame: Baseline

Secondary outcomes

  1. Change in ctHPVDNA and TrHPVDNA levels following definitive intent therapy for early stage disease.

    We will collect bio-specimens and quantify ctHPVDNA and TrHPVDNA levels in plasma and urine, respectively, during their post-treatment visit typically 2-6 weeks post-surgery or last day of treatment visit (chemoradiation).

    Time frame: 2-6 weeks post-treatment
