Prediction of operative mortality based on impairment of host defense systems in patients with esophageal cancer.
To determine whether operative risk based on impaired defense systems can be predicted, we examined 21 markers in 32 patients with esophageal cancer seen between 1983 and 1985 and related them to postoperative deaths. A discriminant analysis proved useful in determining whether the patient would be at risk of operative mortality, based on impaired defense systems. This model, the host defense index (HDI), was then used clinically to evaluate findings in 64 patients seen between 1986 and 1991. During this period, a change in policy for performing transthoracic esophagectomy on and perioperative care for patients with impaired defense systems was associated with a decrease in operative mortality. Thus, the HDI is beneficial to predict the risk of operative mortality based on impaired defense systems in patients with esophageal cancer.
