Objectives:
The risk of postoperative infection after reconstructive oral cancer surgery is high and poses a problem in perioperative management. The objective of this study was to verify the association between preoperative nutritional indicators, surgical site infection (SSI), and long-term prognosis after reconstruction for oral cancer.
Study Design:
Sixty-seven patients admitted to a dental hospital were enrolled. The following nutritional indicators were examined: serum albumin level, modified Glasgow Prognostic Score, Miki's Glasgow Prognostic Score, prognostic nutritional index, platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, lymphocyte/monocyte ratio, and the Controlling Nutritional Status tool. Statistical analyses were conducted to determine potential risk factors for SSI.
Results:
The Cox proportional hazards model demonstrated that SSI and platelet/lymphocyte ratio ≥211.4 were independent prognostic factors affecting survival. The results demonstrated that albumin <4.0 and platelet/lymphocyte ratio ≥211.4 were risk factors for SSI. Furthermore, albumin <4.0, platelet/lymphocyte ratio ≥211.4, and SSI were correlated with prognosis. Preoperative nutritional indicators were associated with SSI and prognosis in patients with oral cancer after reconstructive surgery.
Conclusion:
Preoperative nutritional therapy is crucial for improving therapeutic outcomes in patients with oral cancer who require reconstructive surgery.
