Is perioperative lymphocyte-to-monocyte ratio changes plus CA199 has high value in predicting the prognosis of patients with gastric cancer?

[摘要] We read with great interest the recently published study by Zhu and colleagues entitled “Perioperative lymphocyteto-monocyte ratio changes plus CA199 in predicting the prognosis of patients with gastric cancer” (1). Researchers investigated the relevance of preoperative carbohydrate antigen 199 (CA199) and lymphocyte-to-monocyte ratio changes (ΔLMR) for predicting postoperative survival and develop a nomogram to predict the overall survival rate. However, from the viewpoint of data interpretation and extrapolation, nomogram design and statistical analysis seem inappropriate to answer that question.
