Lo et al. (2017) revealed that low albumin level was associated with a greater tendency to develop postoperative complications in 61 patients who underwent head and neck cancer surgery and simultaneous free tissue transfer. Danan et al. (2016) identified a significant correlation between preoperative hypoalbuminemia and increased probability of wound infection among patients with head and neck cancer. Another report also found that postoperative low albumin level is associated with postoperative complications after free flap transfer (Hoppe, Abernathie & Datiashvili, 2012). The gene discussed is ALB; the disease is Hypoalbuminemia.
