Abstract:
Objective:To investigate the value of dynamic enhanced magnetic resonance imaging (MRI) parameters combined with peripheral blood systemic inflammatory response index (SIRI) in predicting recurrence and metastasis after modified radical triple-negative breast cancer (TNBC) .Methods:A total of 351 TNBC patients who received modified radical surgery in our hospital from Jan. 2019 to Dec. 2021 were followed up for 2 years, and were separated into the recurrence group ( n=32) and the non-recurrence group ( n=319) according to whether they had recurred after surgery. Clinical data of patients were collected, risk factors affecting postoperative recurrence were analyzed, preoperative dynamic enhanced MRI parameters and peripheral blood SIRI level of patients were recorded, and the predictive value of both in postoperative recurrence was analyzed. Results:There were statistically significant differences in clinical stage and preoperative neoadjuvant chemotherapy between the two groups ( χ2=19.56, 7.53, P<0.05). The proportion of irregular tumor morphology in recurrence group was higher than that in non-recurrence group ( χ2=9.031, P<0.05). The levels of transport constant K trans, reflux rate constant K ep and SIRI in the recurrence group were higher ( χ2=15.26, 3.89, 10.10, P<0.05), and there was no statistically significant difference in plasma volume fraction V p and time to peak (TTP) between the two groups ( P>0.05). Multivariate Logistic regression analysis showed that stage III, no neoadjuvant chemotherapy before surgery, irregular tumor shape before surgery, high K trans value, high K ep value and high SIRI level were all risk factors for postoperative recurrence and metastasis in TNBC patients. ROC results showed that the area under the curve (AUC) of preoperative K trans, preoperative K ep and SIRI in predicting postoperative recurrence and metastasis of TNBC patients were 0.797,0.737 and 0.741, respectively. The combined prediction of AUC for postoperative recurrence and metastasis of TNBC patients was 0.797, sensitivity was 59.4%, and specificity was 94.36% (all P<0.05) . Conclusions:High K trans value, high K ep value and high SIRI level are all risk factors for postoperative recurrence and metastasis in TNBC patients. The area under the curve, sensitivity and specificity predicted by their combination for postoperative recurrence and metastasis in patients with TNBC are relatively higher.
