宫颈癌患者血清 LOXL2, PKM2 与根治术后远期复发的关系.

Objective: To study the relationship between serum lysyl oxidase like-2 protein (LOXL2) and pyruvate kinase M2 (PKM2) and long-term recurrence after radical resection in patients with cervical cancer. Methods: 302 patients with cervical cancer who underwent radical surgery in Qilu Hospital of Shandong University Dezhou Hospital from January 2017 to March 2018 were selected as observation subjects, the patients were followed up for 5 years, and 3 cases were lost to follow-up. The patients were divided into recurrence group (72 cases) and non-recurrence group (230 cases) according to whether the patients had long-term recurrence. The levels of serum LOXL2 and PKM2 were compared between recurrence group and non-recurrence group. The influencing factors of long-term recurrence after radical resection were analyzed by multivariate Logistic regression analysis, the predictive value of serum LOXL2 combined with PKM2 for long-term recurrence after radical resection were analyzed by receiver operating characteristic (ROC) curve. Results: There were 72 cases of recurrence in 302 patients 5 years after operation, and the recurrence rate was 23.84% (72/302). The serum levels of LOXL2 and PKM2 in recurrence group were higher than those in non-recurrence group (P<0.05). Multivariate Logistic regression analysis showed that, the surgical mode was laparoscopic surgery, infiltration depth≥ 1/2 muscular layer, lymph node metastasis, elevated LOXL2 and elevated PKM2 were risk factors for long-term recurrence after operation (P<0.05). ROC curve analysis showed that, serum LOXL2 combined with PKM2 had the highest predictive value for long-term recurrence in patients after radical resection, the area under curve (AUC) was 0.921, and the sensitivity was 95.24%. Conclusion: The levels of serum LOXL2 and PKM2 in patients with cervical cancer are increase, and they are risk factors for long-term recurrence after radical resection. Serum LOXL2 combine with PKM2 has a high predictive value for long-term recurrence in patients after surgery. [ABSTRACT FROM AUTHOR]
