Abstract
Purpose
Surgery-induced factors such as postoperative infectious complications (PICs) and intraoperative blood loss (IBL) have a negative impact on the survival of patients undergoing surgery for gastric cancer. A recent study showed that neoadjuvant chemotherapy (NAC) could reduce the negative impact of PICs; hence, we conducted the present study to investigate if NAC can also reduce the negative prognostic impact of IBL.
Methods
We reviewed 115 gastric cancer patients treated with NAC and radical gastrectomy. The cut-off for IBL predicting the long-term survival was assessed by a receiver operating characteristic curve. The Cox proportional hazard model was used to evaluate the association between patient characteristics including IBL, overall survival, and disease-free survival.
Results
The cut-off for IBL was set at 990 ml. Twenty-six patients had excessive IBL exceeding 990 ml (22.6%) and PICs developed in 33 patients (28.7%). The body mass index, IBL, ypT, and ypN were significant independent prognostic predictors, but PICs were not.
Conclusion
NAC did not decrease the risk induced by excessive IBL. The prophylactic effect of NAC on surgery-induced risk was inconsistent.
