Comparative Efficacy of 3L and 2L Integrated Techniques for Gynecologic Cancer-related Lower Extremity Lymphedema: a Retrospective Study

NCT06920732 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 125

No results posted yet for this study

Summary

The goal of this retrospective study is to evaluate the long-term efficacy of 3L versus 2L integrated techniques in patients with gynecologic cancer-related lower extremity lymphedema (GCR-LEL). The main research question is:

Do 3L integrated techniques provide superior long-term outcomes in reducing lower extremity lymphedema compared to 2L techniques in patients with GCR-LEL?

Medical records of patients who have received either 3L or 2L integrated interventions as part of their routine clinical management for GCR-LEL were reviewed and analyzed to assess treatment outcomes over an extended follow-up period.

Conditions

  • Gynecologic Cancer-related Lower Extremity Lymphedema
  • Lymphedema

Interventions

PROCEDURE

VLNT（Vascularized Lymph Node Transfer）

VLNT is a physiologic surgical procedure in which vascularized lymph nodes are harvested from a donor site (e.g., groin or submental region) and transplanted to the affected limb to restore lymphatic drainage. The transferred lymph nodes are anastomosed to recipient vessels to ensure perfusion, aiming to reconstruct lymphatic flow and reduce lymphedema-related swelling and fibrosis.

PROCEDURE

LVA（Lymphaticovenular Anastomosis）

LVA is a supermicrosurgical technique designed to improve lymphatic drainage by creating anastomoses between functional lymphatic vessels and nearby venules. Under high magnification, lymphatic vessels (typically \<0.8 mm) are identified and connected to subdermal venules to bypass obstructed lymphatic pathways, facilitating improved lymph flow and symptom relief in patients with early-stage lymphedema.

PROCEDURE

LS（Liposuction）

LS is a volume-reduction procedure used in the management of advanced lymphedema characterized by fibroadipose tissue hypertrophy. Tumescent liposuction is performed to remove excess subcutaneous adipose tissue, thereby reducing limb volume and improving limb contour. This procedure is often combined with physiologic surgical techniques for optimal long-term outcomes.
