Detection of Tumor DNA Through Cervical Smear and Liquid Biopsy in Endometrial Cancer Patients and Evaluation of Prognostic and Predictive Values of Tumor DNA Assay

August 15, 2022 updated by: Yonsei University
Circulating tumor DNA (ctDNA) may help detect and prognosis-stratify patients with endometrial cancer. Both cervical swab-based genomic DNA (gDNA) and whole blood-based ctDNA can be utilized for this goal. Our objective is to utilize cervical swab and whole blood samples to analyze tumor-derived ctDNA from patients with endometrial cancer. These samples will be collected prospectively, and prior to staging operation. Samples from patients without cancer, who undergo hysterectomy for benign gynecological cause, will be utilized as controls. Variants called by next generation sequencing were classified into four-tiers based on ASCO/AMP system. These initially captured samples will be used to compare performance in terms of detection rate and to stratify patients based on the mutational profile. Additionally, in patients with advanced disease, we plan to collect whole blood samples every 3 months to assess any changes in mutational landscape. Clinical data including age, cormorbidities, treatment methods, date of diagnosis and recurrence, response evaluation for chemotherapy or radiotherapy, survival data will be used to contextualize our findings.
