NCT04817501

Brief Summary

The study evaluates the level and molecular profiles of different CTC populations as markers for predicting the risk of developing hematogenous metastases and the effectiveness of treatment in patients with tumors of the female reproductive system (breast cancer, endometrial cancer, and ovarian cancer). The primary objective are:

  1. 1.To assess the presence and number of different populations of CTCs at different time points (before biopsy, before surgery, and after surgery).
  2. 2.To assess the relationships of different CTCs populations prior to treatment initiation with the effects of neoadjuvant chemotherapy and the risks of recurrence and metastases.
  3. 3.To assess the molecular profiles of different CTCs populations in the blood and in ascitic fluid.

Outcome Measures

Primary Outcomes (1)

  • CTC phenotype

    Different populations of CTCs are evaluated by multicolor flow cytometry and may include: СTC, ascitic tumor cells with stemness features without EMT features; CTC, ascitic tumor cells without stemness and EMT features; CTC, ascitic tumor cells without stemness features and with EMT features; CTC, ascitic tumor cells with stemness features and EMT features; Atypical/hybrid cells without stemness features; Atypical cells.
