Genomic Imprinting Testing for Diagnosis of Bladder Cancer

June 10, 2018 updated by: Zeng Shuxiong, Changhai Hospital

Evaluation of Genomic Imprinting Testing for Detection and Surveillance of Bladder Cancer Patients

Urine analysis provide a promising non-invasive liquid biopsy for diagnosis of bladder cancer. Molecular biomarkers in urine may serve as important diagnostic and prognostic indicators for bladder cancer. Many alterations of genes and proteins have been identified in the urinary for diagnosis of bladder cancer. However, not all bladder cancer patients have the same alterations due to tumor heterogeneity. Thus, to reach satisfactory sensitivity and specificity a new diagnostic molecular alteration should exists ubiquitously in cancers. Numerous studies indicate that Loss of imprinting (LOI) exists ubiquitously in cancers and precede morphological changes. The investigators will conduct a prospective evaluation of a panel of LOI changes in urine test for detection and surveillance of bladder cancer patients.

Study Overview

Detailed Description

During the progression of tumor, molecular changes in both genomics and epigenomics occur prior to morphological changes in cells and tissues, therefore molecular biological test is more sensitive to detect cancer at early stage. Genomic imprinting is one kind of epigenetic regulation that controls gene expression. In detail, a copy of gene on the certain maternal or paternal allele is silenced through methylation, while the other acts normally. This kind of genes are named imprinting genes. Loss of imprinting and Copy number variation (LOI & CNV) is epigenetic change that the silenced copy of an imprinting gene is activated through demethylation. Numerous studies indicate that LOI exists ubiquitously in cancers and precede morphological changes. In contrast, LOI rarely happens in normal somatic cells. Therefore, the methylation status of imprinting genes can act as a biomarker to detect and analyze the abnormal cells.

The investigators will develop a couple of common LOI to establish a predictive diagnostic LOI panel in urine with optimal and robust efficacy in diagnosis of bladder cancer by analyzing LOI in urine from bladder cancer patients and control group that without any tumor in urinary system or other organs. Moreover, the changes of LOI in urine collected before and 1 year after transurethral resection of non-muscle invasive bladder cancer (NIMBC) will also be monitored. External consistency validation will be performed on subsequent urine from patients and control participants collection.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Bladder cancer patients
Diagnosed bladder cancer patients who are being monitored will be the experimental group to develop the LOI panel, and subsequent cohort will be used to confirm the sensitivity and specificity of this urinary analysis.
The changes of LOI The obtained LOI from morning urine and tumor will be tested by LiSen imprinting diagnostic (LSID)
Non-cancer participants
Patients being treated for other diseases but without any tumor or healthy participants will provide a negative control to provide data for developing the LOI diagnostic panel
The changes of LOI The obtained LOI from morning urine and tumor will be tested by LiSen imprinting diagnostic (LSID)
