Comparison of outcomes following postmastectomy radiation therapy in patients with autologous free flap reconstruction depending on the radiation therapy protocol: Systematic review and meta-analysis.

Background: Changes in the standard postmastectomy radiation therapy (PMRT) dosage schedule have led to the development of the hypofractionated radian therapy technique (HRT) that allows patients to receive fewer radian therapy sessions with higher doses in each session. Additionally, advancements in technology introduced the intensity-modulated radiation therapy (IMRT) technique to the widely used three-dimensional conformal radiation therapy. This review aimed to investigate the influence of radiation therapy protocols that may alter the postoperative outcomes of autologous free flap reconstruction.

A meta-analysis of perfusion parameters affecting weight gain in ex vivo perfusion.

Background: Ex vivo machine perfusion (EVMP) has been established to extend viability of donor organs. However, EVMP protocols are inconsistent. We hypothesize that there is a significant relationship between specific parameters during EVMP and perfusion outcomes.
