Abstract

BACKGROUND:

Perioperative oncologic treatments provide a survival benefit for junctional and gastric adenocarcinoma (JGA) and esophageal cancer (EC). Whether neoadjuvant therapy toxicity (NTT) correlates with increased perioperative risk remains unclear. We aimed to evaluate the impact of grade III/IV NTT on postoperative and oncologic outcomes in resected upper gastrointestinal malignancies.

METHODS:

A multicenter retrospective analysis was performed on consecutive patients who benefited from neoadjuvant chemo(radio)therapy followed by surgery between 1997 and 2010 for JGA (first cohort, n = 653) and for EC (second cohort, n = 640). Data between patients who experienced NTT were compared to those who did not.

RESULTS:

NTT was associated with higher postoperative mortality after resection of JGA (P = 0.001) and after esophagectomy (P < 0.001), more non-R0 resections (JGA P = 0.019, EC P = 0.024), a decreased administration of adjuvant treatment among the JGA cohort (P = 0.012), and higher surgical morbidity (JGA P = 0.005, EC P = 0.020). Median survival was reduced in patients who experienced NTT in both cohorts (JGA P = 0.018, EC P = 0.037). After adjustment on confounding variables, NTT was independently associated with postoperative mortality in both cohorts (P ≤ 0.007).

CONCLUSIONS:

NTT is a predictor of postoperative mortality, correlates with higher postoperative morbidity, and negatively affects oncologic outcomes for upper gastrointestinal carcinomas.
