ACS NSQIP risk calculator reliability in head and neck oncology: The effect of prior chemoradiation on NSQIP risk estimates following laryngectomy

The NSQIP Calculator may be poorly calibrated to estimate postoperative complication risk for patients previously exposed to chemoradiation undergoing salvage laryngectomy. Caution should be used when estimating postoperative risk among patients undergoing salvage procedures, especially those of older age, poorer functional status, and those requiring neck dissection.
