History and Perspectives of Hyperradical, Laterally Extended Parametrectomy (LEP)

Area of Science:

• Gynecologic Oncology
• Surgical Oncology
• Cervical Cancer Treatment

Background:

• Cervical cancer remains a significant global health issue, with surgery playing a crucial role in management.
• For early-stage cervical cancer without high-risk factors, surgery and radiotherapy offer equivalent efficacy but differ in complications and quality of life.
• Negative prognostic factors, such as lymph node positivity or tumor involvement of parametrial/surgical margins, worsen outcomes.

Observation:

• A hyper-radical surgical procedure, laterally extended parametrectomy (LEP), was developed in Budapest for high-risk cervical cancer.
• LEP aims for complete pelvic fibro-fatty tissue removal, including lymphatics, lymph nodes, and pelvic sidewall structures.
• Observational studies evaluated LEP as primary treatment for early-stage, high-risk cases and as salvage therapy for recurrent disease post-radiotherapy.

Findings:

• Observational studies on LEP in parametrium/lymph node-positive early-stage cervical cancer show promising results.
• LEP demonstrated potential as a second-line treatment for pelvic sidewall recurrences after radiotherapy.
• These preliminary findings suggest LEP may benefit patients with poor prognoses.

Implications:

• LEP represents a potential surgical advancement for managing high-risk cervical cancer, especially when radiotherapy is contraindicated.
• The promising results warrant further investigation through prospective randomized trials.
• Clarifying LEP's role could improve treatment strategies and outcomes for a challenging patient cohort.
