Abstract

Head and neck cancer requiring free-flap reconstruction is associated with relatively high mortality. We aimed to evaluate perioperative risk factors for 1-year mortality in this patient group. This is a single-center retrospective analysis of 204 patients operated during 2008 to2018. A total of 47 (23.0%) patients died within 1year. In univariate analysis, there were no differences in the intraoperative course between 1-year survivors and nonsurvivors. Among the 1-year nonsurvivors, preoperative albumin level was lower (39 [36 to 43] vs 42 [39 to 44], P=.032) and the Sequential Organ Failure Assessment admission score was higher (4 [3 to 5] vs 3 [2 to 4], P=.003) than those of the 1-year survivors. Among the nonsurvivors, the preoperative and postoperative levels of leukocytes were higher (7.6 [6.7 to 9.5] vs 6.9 [5.5 to 8.4], P=.002; 11.4 [9.0 to 14.2] vs 8.7 [7.2 to 11.3], P<.001). The highest odds ratios for 1-year mortality in multivariate analysis were American Society of Anesthesiologists A classification greater than 2 (3.9 CI 1.4 to 10.5), male gender (4.0 CI 1.5 to 11), and increase in leukocyte count (1.3 CI 1.1 to 1.5). One-year nonsurvivors had higher American Society of Anesthesiologists classification and were more often men. The postoperative inflammatory markers were higher in nonsurvivors, while the intraoperative course did not have a significant impact on the 1-year mortality.

  • In our previous article assessing the long-term outcomes and causes of deaths after freeflap surgery (FFS) for cancer of the head and neck, we found patient-related factors including low body mass index and advanced American Society of Anesthesiologists (ASA) classification as the most significant risk factors for poor long-term mortality
