This systematic review and meta-analysis evaluated the effectiveness of prophylactic lymphovenous shunting (LVS) in preventing secondary lymphedema in 2261 patients undergoing axillary and inguinal lymph node dissection. The study found that prophylactic ILR significantly reduced the incidence of postoperative lymphedema, with a pooled odds ratio of 0.27 (95% CI 0.17-0.42; p < 0.01).
Key findings
- Prophylactic ILR reduced lymphedema incidence to 12.5% compared to 24.2% in controls.
- Pooled odds ratio for lymphedema was 0.27 (95% CI 0.17-0.42; p < 0.01).
- Subgroup analysis showed no significant difference in treatment effect between upper- and lower-limb procedures.
- Trim-and-fill adjustment indicated persistent protective association with adjusted OR of 0.37 (p < 0.0001).
Why it matters
Secondary lymphedema is a common complication following lymph node dissection in cancer patients, leading to significant morbidity. Understanding effective preventive strategies like prophylactic ILR can help improve patient outcomes and quality of life.
What to keep in mind
Confidence in the treatment effect is limited by the predominance of observational studies and potential publication bias.
