Third-Generation Nanopore HPV Integration Site for Precise Prediction of Cervical Cancer Prognosis
Development of a Third-Generation Nanopore HPV Integration Site Detection Kit for Precise Prediction of Cervical Cancer Prognosis
Source: ClinicalTrials.gov · Last updated 16 Oct 2024
Brief summary (registry, in English)
Cervical cancer is a significant health threat to women, with over 500,000 new cases and approximately 342,000 deaths worldwide annually, and about 107,000 new cases in China with 51,000 fatalities. Current screening methods include HPV testing, cytology, colposcopy, and biopsy, but none can detect HPV genome integration in persistently positive patients. Our team has analyzed over 200 cervical cell samples using third-generation nanopore technology, focusing on HPV integration sites. We've developed a proprietary long-fragment capture and sequencing method (reads averaging 2-5kb) that identifies precise HPV insertion points and detects the complete Human-Virus-Human (H-V-H) viral insertion sequence. We found overlaps in HPV integration genes across different stages of cervical intraepithelial neoplasia (CIN) and in cancer patients with recurrence and metastasis, suggesting potential biomarkers for tumor progression and poor prognosis. We also analyzed HPV sequence proportions and gene insertion numbers in samples from patients before and after radical radiochemotherapy, providing insights into treatment efficacy and prognosis. Our study aims to use a domestic nanopore sequencing platform and probes tailored to Chinese HPV infection patterns to detect integration sites in late-stage cervical cancer and post-treatment recurrence/metastasis patients. We aim to optimize our method to complete the entire detection process within eight hours, expanding the technology's application in point-of-care diagnostics and decentralization.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- A. Confirmed by pathology as neuroendocrine carcinoma of the cervix; B. Have not undergone standardized radical treatment (for the cohort of stage IIIB and later cervical cancer patients, those who have not undergone standardized radical radiochemotherapy must be excluded. For the cohort of patients who have local recurrence or distant metastasis after radical radiochemotherapy, those who have only had cervical cancer surgery and recurrence, and those who have not undergone standardized radiochemotherapy after cervical cancer surgery must be excluded); C. HPV testing is negative, and there is no clear integration site of HPV in the genome; D. The patient or family members are unable to cooperate with the study or cannot provide written informed consent.
Who the study is looking for
- A. Undergoing radical radiochemotherapy at our institution or a collaborating institution; B. Pathologically confirmed as cervical cancer; C. Diagnosed as an advanced-stage patient (FIGO staging IIIB, IIIC, IVA, IVB), or a patient who has experienced local recurrence or distant metastasis after radical radiochemotherapy; D. Capable of regular follow-up visits; E. The patient or their family can understand the research protocol and are willing to participate in this study, providing written informed consent.
