Value of CT tumor volume measurement parameters combined with laboratory indexes in guiding preoperative staging prediction in patients with colon cancer
Objective To analyze the application value of CT tumor volume measurement parameters combined with preoperative laboratory indexes in preoperative staging prediction.Methods A total of 75 patients with colon cancer admitted in Feicheng People's Hospital from March 2021 to September 2023 were selected.Taking the pathological examination results as the gold standard,the patients were divided into stage Ⅰ-Ⅱ group and stage Ⅲ-Ⅳ group according to pTNM stages.The parameters of CT tumor volume,including tumor length(Tien),tumor maximum diameter(Tdia),tumor maximum area(Tare)and tumor volume(Tvol),were measured,and their blood lipids,coagulation indexes and serum albumin(ADL)were detected,and lactate dehydrogenase to albumin ratio(LAR)was calculated.The different indexes of patients with different pTNM stages of colon cancer were summarized,the area under the curve(AUC)of each index to evaluate colon cancer stages individually and jointly were drawn using receiver operating characteristic curve(ROC),and the predictive efficiency was calculated.Results Among 75 patients with colon cancer,there were 11 cases in stage Ⅰ,25 cases in stage Ⅱ,33 cases in stage Ⅲ and 6 cases in stage Ⅳ.There was no significant difference in baseline data between stageⅠ-Ⅱ and stage Ⅲ-Ⅳ groups(P＞0.05).Tien,Tdia,Tare and Tvol in stage Ⅰ-Ⅱ group were lower than those in stage Ⅲ-Ⅳ group(P＜0.05).There was no significant difference in blood lipid levels between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ groups(P＞0.05).The coagulation indexes(PT,APTT,FIB and D-D)and LAR in Ⅰ-Ⅱ stage group were lower than those in Ⅲ-Ⅳ stage group(P＜0.05).The AUC of predicting the staging of colon cancer patients by combining all the indexes was 0.880,and the sensitivity and specificity were 94.44％and 82.05％,respectively.Conclusion The progress of staging of colon cancer patients is accompanied by the changes of CT tumor volume measurement parameters,coagulation indexes and LAR.The combination of the above indexes can provide reliable reference for preoperative staging prediction.
