Systematic Construction and Validation of an Immune‐Related Gene‐Based Model to Predict Prognosis for Ovarian Cancer

Ovarian cancer (OC) is a malignancy with poor prognosis, stubborn resistance, and frequent recurrence. Recently, it has been widely recognized that immune‐related genes (IRGs) have demonstrated their indispensable importance in the occurrence and progression of OC. Given this, this study aimed to identify IRGs with predictive value and build a prognostic model for a more accurate assessment. First, we obtained transcriptome and clinical information of ovarian samples from both TCGA and GTEx databases. After integration, we figured out 10 genes as immune‐related prognostic genes (IRPGs) by performing the univariate Cox regression analysis. Subsequently, we established a TF‐associated network to investigate its internal mechanism. The prognosis model consisting of 5 IRPGs was constructed later by lasso regression analysis. The comparison of the score with the clinical factors validated its independence and superiority in OC’s prognosis. Moreover, the association between the signature and immune cell infiltration demonstrated its ability to image the immune situation of the tumor microenvironment. Finally, the reliability of the risk model was confirmed by the GEO cohort. Together, our study has constructed an independent prognostic model for OC, which may deepen the understanding of the immune microenvironment and help present novel biomarkers or ideas for targeted therapy.

A multicenter phase 2 trial of camrelizumab plus famitinib for women with recurrent or metastatic cervical squamous cell carcinoma

AbstractThis phase 2 study assesses the efficacy and safety of camrelizumab (an anti-PD-1 antibody) plus famitinib (anti-angiogenic agent) in women with pretreated recurrent or metastatic cervical cancer (ClinicalTrials.gov NCT03827837). Patients with histologically or cytologically confirmed cervical squamous cell carcinoma experiencing relapse or progression during or after 1–2 lines of systemic therapy for recurrent or metastatic disease are enrolled. Eligible patients receive camrelizumab 200 mg intravenously on day 1 of each 3-week cycle plus famitinib 20 mg orally once daily. The primary endpoint is the objective response rate. Secondary endpoints are duration of response, disease control rate, time to response, progression-free survival, overall survival, and safety. The trial has met pre-specified endpoint. Thirty-three patients are enrolled; median follow-up lasts for 13.6 months (interquartile range: 10.0–23.6). Objective responses are observed in 13 (39.4%, 95% confidence interval [CI]: 22.9–57.9) patients; the 12-month duration of response rate is 74.1% (95% CI: 39.1–90.9). Median progression-free survival is 10.3 months (95% CI: 3.5–not reached) and the 12-month overall survival rate is 77.7% (95% CI: 58.9–88.7). All patients experience treatment-related adverse events; grade ≥3 events occur in 26 (78.8%) patients. Treatment-related serious adverse events and deaths are observed in 9 (27.3%) and 2 (6.1%) patients, respectively. Camrelizumab plus famitinib shows promising antitumor activity with a manageable and tolerable safety profile in patients with pretreated recurrent or metastatic cervical squamous cell carcinoma. This combination may represent a treatment option for this population.
