Background:
The systemic inflammation score (SIS), as calculated from preoperative serum albumin level and lymphocyte-to-monocyte ratio, has been demonstrated to be a prognostic marker in cancer. The present study intended to investigate the prognostic role of SIS in gastric cancer patients after curative gastrectomy in comparison with other prognostic markers.
Methods:
Preoperative SIS was retrospectively calculated in patients who underwent curative gastrectomy between 2007 and 2011 in Fudan University Shanghai Cancer Center. The prognostic accuracy of each score was compared utilizing time-dependent receiver operating characteristics analysis.
Results:
The higher SIS score was associated with older age, larger tumour size, a more advanced tumour-nodes-metastasis stage and lymph node status, deeper tumour invasion, the presence of lymphovascular invasion and a poorer overall survival and disease-free survival. In time-dependent receiver operating characteristics analysis, the SIS had a higher area under the curve for the prediction of 5-year overall survival than the neutrophil lymphocyte ratio. The SIS maintained the predictive accuracy superiority throughout the observation period.
Conclusion:
The SIS is a useful prognostic marker in gastric cancer patients after curative gastrectomy.
