Circulating tumor cells in gynaecological malignancies.

Area of Science:

• Oncology
• Molecular Biology
• Gynecology

Background:

• Non-invasive diagnostic and therapeutic approaches for malignant diseases are advancing.
• Circulating tumor cells (CTCs) are shed from primary tumors into the bloodstream and indicate metastatic potential.
• Various enrichment and isolation methods exist for detecting CTCs from peripheral blood.

Purpose of the Study:

• To review the role of CTCs in the diagnosis, treatment management, prognosis, and early recurrence detection of gynecological malignancies.
• To explore specific applications of CTC detection in endometrial, cervical, and ovarian cancers.

Main Methods:

• Characterization of three major CTC detection categories: nucleic acid-based, physical properties-based, and antibody-based.
• Review of current literature on CTC detection in gynecological cancers.

Main Results:

• CTCs in endometrial cancer correlate with worse overall survival; gene analysis can guide systemic therapy decisions.
• Human papillomavirus (HPV) viral oncogene transcripts are potential markers for cervical cancer detection.
• CTCs aid in differentiating ovarian cancer from benign masses and are independent of biomarkers like CA125 and HE4.
• Post-surgery CTC detection may indicate residual disease, and combined gene analysis enhances specificity.

Conclusions:

• CTCs represent a promising tool for non-invasive monitoring and management of gynecological cancers.
• Specific CTC markers and detection strategies can improve diagnostic accuracy and treatment personalization.
• Further research into CTCs will enhance early detection and improve patient outcomes in gynecological oncology.
