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.
