Abstract:

Objective To evaluate the predictive role of preoperative mean corpuscular hemoglobin concentration(MCHC) in peripheral blood for postoperative recurrence in patients with intrahepatic cholangiocarcinoma(ICC).Methods A retrospective study was conducted on 114 ICC patients who underwent their first hepatectomy at Zhongshan Hospital of Fudan University from April 2018 to November 2022. Comprehensive clinical data and laboratory test results were collected. The patients were followed up. Receiver operating characteristic(ROC) curve analysis was performed to evaluate the predictive performance of MCHC for postoperative recurrence in ICC patients,and its optimal cut-off value was obtained. Kaplan-Meier survival curve was constructed to analyze postoperative recurrence in ICC patients. Cox regression analysis was used to evaluate the independent risk factors for postoperative recurrence in ICC patients.Results During the follow-up period,59 cases experienced postoperative recurrence. The optimal cut-off value of MCHC for postoperative recurrence in ICC patients was 341 g·L-1. There was statistical significance in tumor numbers and American Joint Committee on Cancer(AJCC)staging between MCHC<341 g·L-1 group and MCHC≥341 g·L-1 group(P<0.05),while other clinicopathologic characteristics showed no statistical significance(P>0.05). The recurrence-free survival rate was higher in MCHC≥341 g·L-1 group compared to MCHC<341 g·L-1 group(Log-rank χ2=4.304,P=0.038). Child Grade B,lymphatic metastasis,and MCHC<341 g·L-1 were identified as independent risk factors for postoperative recurrence in ICC patients [hazard ratios(HR) were 0.049,2.106 and 0.521,95% confidence intervals(CI) were 0.006-0.426,1.238-3.577 and 0.290-0.937,respectively,P<0.05].Conclusions Preoperative MCHC is associated with the prognosis of ICC patients. Lower MCHC in ICC patients is associated with increased postoperative recurrence risk and poorer prognosis.
