ObjectiveTo summarize the research progress of Hippo signaling pathway in triple negative breast cancer (TNBC). MethodLiteratures about studies the role of Hippo signaling pathway in cancer stem cells, epithelial-mesenchymal transformation, tumorigenesis and development, distant metastasis, treatment resistance, and treatment strategies were retrieved. ResultsIn TNBC, overexpression of Yes-associated protein and PDZ-binding motif could promote the development of tumor stem cells, induce epithelial-mesenchymal transformation of TNBC cells, and promote tumor development, distant metastasis, and chemotherapy resistance. ConclusionHippo/Yes-associated protein axis plays an important role in carcinogenesis and progression of TNBC, and targeting Hippo signaling pathway might be a potential therapeutic target for TNBC.
ObjectiveTo compare the diagnostic accuracy, sampling satisfaction, and safety of ultrasound-guided core needle biopsy (CNB) and fine needle aspiration biopsy (FNA) for thyroid nodules.MethodsThe databases of PubMed, Medline, Web of Science, Cochrane Library, Wanfang, CNKI, and CBM were searched to collect the relevant studies on the diagnostic performance, sampling satisfaction, and safety of ultrasound-guided CNB and FNA for thyroid nodules. Revman 5.3 and Stata 15 software were used for meta-analysis.ResultsA total of 24 studies involving 25 388 patients were included. Meta analysis showed that: compared with CNB, FNA had poor diagnostic accuracy ［OR=0.26, 95%CI (0.15, 0.46), P<0.000 01］, poor sampling satisfaction ［OR=0.20, 95%CI (0.12, 0.33), P<0.000 01］, lower incidence of total complications ［OR=0.28, 95%CI (0.16, 0.50), P<0.000 1］, and lower incidence of bleeding after biopsy ［OR=0.62, 95%CI (0.48, 0.81), P=0.000 3］. However, there was no significant difference in the pain score ［WMD=–0.21, 95%CI (–0.57, 0.15), P=0.26］ between the two groups. Subgroup analysis showed that there was no significant difference in the accuracy of biopsy diagnosis of thyroid nodules with diameter less than 10 mm between the two groups ［OR=0.52, 95%CI (0.15, 1.81), P=0.30］, however, the accuracy of CNB in the diagnosis of thyroid nodules with diameter ≥ 10 mm was still better than FNA ［OR=0.26, 95%CI (0.12, 0.56), P=0.000 5］.ConclusionsCompared with FNA, ultrasound-guided CNB has a certain advantages in sampling satisfaction and the diagnosis accuracy of thyroid nodules with diameter ≥ 10 mm. CNB is better than FNA, but will bring higher risk of complication.
ObjectiveTo investigate the relationship between the expression of IL-8 protein in triple negative breast cancer (TNBC) and clinicopathological features and survival prognosis.MethodsThe expression of IL-8 protein in 80 cases of TNBC was detected by immunohistochemical staining, and the relationship between the expression of IL-8 protein and clinicopathological features and prognosis of TNBC patients was analyzed by χ2 test, log-rank test, and Cox proportional hazards regression.ResultsIn 80 TNBC patients, the high expression of IL-8 protein accounted for 22.5% (18/80). The expression level of IL-8 protein in TNBC tumor tissue was correlated with T stage, clinical stage, Ki-67 expression, WHO grade and lymph node metastasis (P<0.05). However, it was not related to age, menopausal status, pathological type of tumor and whether they had received neoadjuvant chemotherapy (P>0.05). The results of log-rank analysis showed that the disease-free survival rate (DFS) of high expression group of IL-8 protein was poor than that of low expression group of IL-8 protein (P<0.05). Multivariate Cox proportional hazards regression analysis showed that the expression of IL-8 protein was an independent factor affecting the survival and prognosis of TNBC patients [HR=1.180, 95%CI (1.001, 1.391), P=0.049]. The prognosis of TNBC patients with high expression of IL-8 protein was poor.ConclusionThe expression level of IL-8 protein is an independent risk factor affecting the survival and prognosis of patients with TNBC.
