Implication

Growth factor gene therapy (VEGF-C or VEGF-D) coupled with lymph node transfer successfully repairs damaged lymphatic networks and improves drainage in a large animal model of lymphedema.

Key Points

To evaluate the therapeutic efficacy of autologous lymph node transfer paired with adenoviral VEGF-C or VEGF-D delivery in a porcine model of limb lymphedema.
Created lymphatic vascular defects within a 3-cm radius around an inguinal lymph node in pigs.
Reconstructed lymphatic networks using autologous lymph node grafts paired with adenoviral delivery of VEGF-C (n=5), VEGF-D (n=9), or AdLacZ control vectors (n=5).
Both VEGF-C and VEGF-D induced robust new lymphatic vessel growth and significantly improved postoperative lymphatic drainage compared with controls.
Transferred lymph node architecture was best preserved with VEGF-C, which also avoided the transient postoperative seroma fluid accumulation observed with VEGF-D.

Structured PICO

Autologous lymph node transfer combined with adenovirally delivered vascular endothelial growth factor (VEGF)-C (n=5) or VEGF-D (n=9)

Comparator

Autologous lymph node transfer combined with adenovirally delivered AdLacZ (β-galactosidase) (n=5)

Outcome

Growth of new lymphatic vessels and postoperative lymphatic drainagesurrogate

Growth factor gene therapy (VEGF-C or VEGF-D) coupled with lymph node transfer successfully repairs damaged lymphatic networks and improves drainage in a large animal model of lymphedema.

Cite This Study

Lähteenvuo et al. (2011) studied Limb lymphedema (n=19). Autologous lymph node transfer combined with adenoviral VEGF-C or VEGF-D vs. AdLacZ (β-galactosidase) was evaluated on Lymphatic drainage and growth of new lymphatic vessels. Autologous lymph node transfer combined with adenoviral VEGF-C or VEGF-D significantly improved postoperative lymphatic drainage and induced robust growth of new lymphatic vessels compared with controls.
