Preoperative NLR and PLR were found to be correlated to unfavorable histopathologic features of cervical cancer. The preoperative NLR, but not PLR, may be used as a potential and easy biomarker for survival prognosis in patients with cervical cancer receiving initial radical hysterectomy with pelvic lymphadenectomy.

The development of multifunctional nanoscale radiosensitizers has attracted a tremendous amount of attention, which can enhance the radiosensitization of tumor tissues and reduce unnecessary damage to the surrounding organs. However, the persistent hypoxia environment within the tumor limits their applications in radiotherapy. In this paper, a stable nanocomposite was engineered to overcome the hypoxia properties by using 1,4-benzenedicarboxylic acid produced from a Zr-MOF as a carbonic anhydrase IX (CA IX) inhibitor and quercetin (QU) as a radiosensitizer. QU was encapsulated into the Zr-MOF structure to achieve a synergetic dual sensitization therapy. Zr-MOF-QU exhibits an excellent potential of radiotherapy sensitization characteristics in vitro and in vivo from the γ-H2AX immunofluorescence staining and colony assays. The mechanisms of alleviating hypoxia-induced resistance and sensitizing tumor tissues to improve cell apoptosis from radiation were found to suppress CA IX expressions by the decomposition product from Zr-MOF and boost the sensitivity by QU in radiation therapy. Moreover, there was no significant systemic toxicity during the treatment, and the therapeutic outcome was assessed in animal models. Therefore, our results demonstrate a promising cancer treatment approach in the radiation field.

Tumor necrosis factor alpha-induced protein 8 (TNFAIP8) is an apoptosis regulator proven to have an important function in the proliferation, invasion, metastasis, and progression of malignancies. In this study, we investigated the clinical role of TNFAIP8 overexpression in endometrial cancer (EC) and determined the relationship of TNFAIP8 with the proliferative antigen Ki-67 and metastasis-related gene matrix metallopeptidase 9 (MMP9) in 225 tumor specimens by immunohistochemistry and western blot, in order to elucidate more information on the role of TNFAIP8 protein with regard to the pathogenesis of EC. An association was observed between TNFAIP8 overexpression and clinicopathologic factors, such as advanced International Federation of Gynecology and Obstetrics stage (P<0.001), higher histologic grade (P=0.017), deep myometrial invasion (P=0.030), lymphovascular space invasion (P=0.011), lymph node metastasis (P<0.001), and recurrence. Furthermore, TNFAIP8 overexpression was strongly correlated with MMP9 and Ki-67 expression in the progression of ECs. Patients with high expression of TNFAIP8 (P<0.001 for both) and Ki-67 (P=0.007 and P=0.008) had poor overall survival and disease-free survival (DFS) rates. MMP9 overexpression did not affect survival outcomes (P>0.05). Multivariate Cox regression analysis revealed that TNFAIP8 (P=0.029) and lymph node metastasis (P=0.022) were independent factors of DFS in patients with EC. These findings suggested that TNFAIP8 may be used as a prognostic marker for the recurrence of EC, and its promotion of the proliferation and metastasis in EC may be due to its mediation of Ki-67 and MMP9.

Overexpression of Wnt7a may contribute to the progression of endometrial cancer and thus may serve as a new biomarker to predict the prognosis of endometrial cancer.
