In cervical cancer, Qin et al. (2017) indicated that HPV-induced somatic mutations and a multitude of neoantigens, which played a crucial role in the inhibitory tumor microenvironment and could lead to notable alterations among checkpoint-related genes such as CTLA-4, PD-1, and PD-L1. Specifically, PD-L1 showed a positive correlation with ENO1, PRDM1, OVOL1, and MNT, all of which are related master regulators of HPV16 E6 and E7 (Qin et al., 2017). Of note, a single-arm, phase II study investigated durvalumab in patients with recurrent/metastatic HNSCCs (= 112) and found that HPV-positive patients had a higher response rate and better survival than that of the HPV-negative patients (Zandberg et al., 2018). Nevertheless, for cervical cancer, the association of HPV status and the efficacy of PD-1/PD-L1 inhibitors is not yet certain due to the paucity of available data. Several studies have probed the role of PD-L1 expression in the prognosis and therapeutic efficacy of cervical cancer. These results separately proved that an increase in PD-L1 expression was positively associated Rabbit polyclonal to NFKB3 with tumor metastasis (Yang et al., 2017), tumor progression (Hsu et al., 2018) and poor prognosis in cervical cancer (Heeren et al., 2016). In this regard, the negative relationship between HPV infection and the clinical outcomes of cervical cancer may be partially attributed to the PD-L1 expression induced by HPV infection (Yang et al., 2017). For patients with locally advanced cervical adenocarcinoma and adenosquamous carcinoma treated with CRT, the underexpression of PD-L1 was a prognostic factor for tumor relapse (= 0.041), indicating that PD-L1 expression might be a novel biomarker for CRT outcome (Lai et al., 2017). Clinical Research Outcomes of PD-1/PD-L1 Inhibitors in Cervical Cancer Since 2015, multiple clinical trials have been conducted to explore the application of PD-1/PD-L1 antibodies in cervical cancer. To date, four studies have yielded preliminary results (Table 2). Keynote 028 (a phase Ib study) and Keynote 158 (a phase II study) evaluated pembrolizumab at the dose of 10 mg/kg and 200 mg/kg, respectively, in recurrent, metastatic cervical cancer. In Keynote 028 (Frenel et al., 2017), 24 patients were enrolled, and the overall response rate (RECIST v1.1) was 17% (95% CI: 5 to 37%). In terms of toxicity, 5 patients experienced grade 3 AEs (NCI-CTCAE 3.0), while no grade 4 AEs was observed. In Keynote 158 (Schellens et al., 2017), 98 patients with recurrent or metastatic cervical cancer were enrolled. With a median follow-up time of 11.7 months, the ORR in 77 patients was 14.3% (95% CI: 7.4 to 24.1%), including 2.6% of the patients with CRs and 11.7% of patients with PRs, whereas no response was observed in patients without PD-L1 expression in tumor cells. The most frequent serious adverse reactions included anemia (7%), fistula (4.1%), hemorrhage (4.1%), and infection (4.1%). Based on Keynote 158, the FDA approved pembrolizumab on June 12, 2018, for advanced cervical cancer with disease progression during or after chemotherapy1. Checkmate 358 (Hollebecque et al., 2017) (phases ICII studies) adopted nivolumab (200 mg/kg q2w) for the treatment of recurrent, metastatic cervical cancer and resulted in an ORR of 26.3%. The disease control rate was 70.8%. The related grades 3C4 toxic effects included hyponatremia, syncope, diarrhea, and hepatocellular injury. From these three studies, pembrolizumab and nivolumab showed promising antitumor effects and were well-tolerated in patients with recurrent or metastatic cervical cancer. However, due to a limited follow-up time, PFS and OS were not reported. Additionally, the REGN2810 study (Papadopoulos et al., 2016), a phase I multicenter study, assessed REGN2810 (a PD-1 mAb) as a monotherapy and in combination with hfRT, in combination with cyclophosphamide (CTX) or with CTX + hfRT in patients with advanced solid tumors, including cervical cancer. This study adopted a dose escalation design, and as of February 2016, no dose-limiting toxicity (DLT) was observed. The most common treatment-related AEs were fatigue (= 14, 24.1%), arthralgia (= 7, 12.1%), and nausea (= 6, 10.3%).

Clinical Analysis Final results of PD-1/PD-L1 Inhibitors in Cervical Cancers Since 2015, multiple scientific trials have already been executed to explore the use of PD-1/PD-L1 antibodies in cervical cancers. To time, four studies have got yielded preliminary outcomes (Desk 2). Keynote 028 (a stage Ib research) and Keynote 158 (a stage II research) examined pembrolizumab on the dosage of 10 mg/kg and 200 mg/kg, respectively, in repeated, metastatic cervical cancers.

Using a median follow-up period of 11.7 months, the ORR in 77 sufferers was 14.3% (95% CI: 7.4 to 24.1%), including 2.6% from the sufferers with CRs and 11.7% of sufferers with PRs, whereas no response was seen in sufferers without PD-L1 expression in tumor cells. The most typical serious effects included anemia (7%), fistula (4.1%), hemorrhage (4.1%), and an infection (4.1%). Predicated on Keynote 158, the FDA accepted pembrolizumab on June 12, 2018, for advanced cervical cancers with disease development during or after chemotherapy1. Checkmate 358 (Hollebecque et al., 2017) (stages ICII research) followed nivolumab (200 mg/kg q2w) for the treating repeated, metastatic cervical cancers and led to an ORR of 26.3%. The condition control price was 70.8%. The related levels 3C4 toxic results included hyponatremia, syncope, diarrhea, and hepatocellular damage. From these three research, pembrolizumab and nivolumab demonstrated promising antitumor results and had been well-tolerated in sufferers with recurrent or metastatic cervical cancers. However, because of a restricted follow-up period, PFS and Operating-system weren’t reported. Additionally, the REGN2810 research (Papadopoulos et al., 2016), a stage I multicenter research, evaluated REGN2810 (a PD-1 mAb) being a monotherapy and in conjunction with hfRT, in conjunction with cyclophosphamide (CTX) or with CTX + hfRT in sufferers with advanced solid tumors, including cervical cancers.
