Postoperative consequences of cancer cachexia after head and neck free flap reconstruction

Abstract

Background

Cachexia is detrimental for patients with head and neck cancer (HNC). However, postoperative consequences of HNC cachexia remain unknown.

Methods

A 2014–2019 retrospective review was performed of adults undergoing aerodigestive HNC resection with free tissue reconstruction. Propensity score matching using inverse probability of treatment weighting (IPTW) of cachectic and control groups was employed to adjust for covariate imbalances followed by binary logistic regression on postoperative outcomes.

Results

Out of 252 total patients, 135 (53.6%) had cancer cachexia. The cohort was predominantly white (94.4%) males (65.1%) aged 61.5 ± 11.5 years with stage III–IV (84.1%) malignancy of the oral cavity (66.3%). After matching cohort pre- and intra-operative covariates using IPTW, cancer cachexia remained a strong, significant predictor of serious National Surgical Quality Improvement Program (NSQIP) complications (OR [95%CI] = 3.84 [1.80–8.21]) and major Clavien-Dindo complications (OR [95%CI] = 3.00 [1.18–7.60]).

Conclusions

Cancer cachexia is associated with worse HNC free flap reconstruction outcomes.
