Role of Genomic Imprinting in Cancer Diagnosis

• Conditions: Genomic Imprinting; Cancer; Biomarker; Early Diagnosis

• Registration Number: NCT03882684
• Lead Sponsor: Chinese Alliance Against Lung Cancer

Brief Summary

The current research focus for cancer diagonosis is classical genetics, named "driving genes". However, not all cancer patients have typical genetic alterations, especially at early stage. In the past dacades, accumulating evidences have revealed that more than 80% diseases are closely related to epigenetic changes. The normally silenced copy of imprinted genes are reactivated at early stage of cancers, and finally proceed to copy number variation. This study will screen for a panel of imprinted genes and build quantitative models to assist the diagnosis of multiple cancers.

Primary Outcome Measures

Name	Time	Method
Specificity of imprinting cancer early detection	In the middle of the study, an average of 15 months	Number of patients "declared negative" with the imprinting early detection among the patients who are with benign tumors or other diseases
Sensitivity of imprinting cancer early detection	In the middle of the study, an average of 15 months	Number of patients "declared positive" with the imprinting early detection among the patients suffered from cancer

Secondary Outcome Measures

Name	Time	Method
Comparison of the sensitivity of the imprinting detection versus cytopathology	In the middle of the study, an average of 15 months	Number of patients "declared positive" with the imprinting early detection versus patients "declared positive" with the cytopathology
Comparison of the specificity of the imprinting detection versus cytopathology	In the middle of the study, an average of 15 months	Number of patients "declared negative" with the imprinting early detection versus patients "declared negative" with the cytopathology
