Brief Summary

Copy number variation(CNV) refers to ongoing chromosome segregation errors throughout consecutive cell divisions. CNV is a hallmark of human cancer, and it is associated with poor prognosis, metastasis, and therapeutic resistance. Analyzing CNV of the DNA extracted from bile samples in gallbladder seems a promising method for diagnosing, monitoring, and predicting the prognosis of patients with gallbladder cancer. CNV can be assessed using experimental techniques such as bulk DNA sequencing, fluorescence in situ hybridization (FISH), or conventional karyotyping. However, these techniques are either time-consuming or non-specific. The investigators here intend to study whether a new method named Ultrasensitive Chromosomal Aneuploidy Detection (UCAD), which is based on low-coverage whole-genome sequencing, can be used to analyze CNV thus helping diagnose gallbladder cancer and assessing follow-up.

Outcome Measures

Primary Outcomes (1)

  • UCAD can be used as a diagnostic technology for gallbladder cancer with the sensitivity more than 90%

    Ultrasensitive chromosomal aneuploidy detection (UCAD) uses low-coverage whole-genome sequencing technology to detect DNA chromosomal instability in samples. By detecting DNA extracted from patients' bile and blood, bioinformatics can be used to analyze the differences in CNV between benign and malignant gallbladder diseases, and a prediction model for gallbladder cancer.
