The effects of neoadjuvant therapy on morbidity and mortality of esophagectomy for esophageal cancer: American college of surgeons national surgical quality improvement program (ACS–NSQIP) 2005–2012

Objective

This study used a multi-center database to evaluate the impact of neoadjuvant therapy on the 30-day morbidity and mortality following esophagectomy for esophageal cancer.

Methods

The NSQIP database was queried for 2005–2012 for patients, who had esophagectomy for esophageal cancer. Patients were divided into two groups: neoadjuvant therapy and esophagectomy only.

Results

The neoadjuvant group had a lower rates of sepsis (8% vs. 13%, unadjusted P = 0.004) and acute renal failure (0.4% vs. 2%, unadjusted P = 0.01), and a higher rate of pulmonary embolism (PE) (3% vs. 1%, unadjusted P = 0.04). The adjusted odds of PE for patients, who received neoadjuvant therapy were 2.8 times the odds of PE for patients in the esophagectomy group, controlling for BMI. The association with renal failure was not significant, when one adjusted for race. There was no difference in the rates of reoperation, readmission, stroke, cardiac arrest, MI, surgical site and deep organ infections, anastomosis failure, blood transfusions, DVT, septic shock, pneumonia, UTI, respiratory failure, and 30-day mortality between the two groups.

Conclusions

We conclude that neoadjuvant therapy followed by esophagectomy for esophageal cancer does not have a negative impact on 30-day mortality. Neoadjuvant therapy is associated with increased odds of PE. J. Surg. Oncol. © 2016 Wiley Periodicals, Inc.
