Díaz-Rivera J, Rodríguez-Rivera MA, Meléndez-Vázquez NM, Godoy-Vitorino F, Dorta-Estremera SM. Immune and Microbial Signatures Associated with PD-1 Blockade Sensitivity in a Preclinical Model for HPV+ Oropharyngeal Cancer. Cancers (Basel) 2024; 16:2065. [PMID: 38893183 PMCID: PMC11171047 DOI: 10.3390/cancers16112065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 05/17/2024] [Accepted: 05/23/2024] [Indexed: 06/21/2024] Open
Abstract
The United States is suffering from an epidemic associated with high-risk strains of the Human Papillomavirus (HPV) predominantly responsible for the development of head and neck squamous cell carcinoma (HNSCC). Treatment with immune checkpoint inhibitors targeting programmed death 1 (PD-1) or its ligand PD-L1 has shown poor efficacy in HNSCC patients, observing only a 20-30% response. Therefore, biological marker identification associated with PD-1 blockade response is important to improve prognosis and define novel therapeutics for HNSCC patients. Therapy response was associated with increased frequencies of activated CD27+T cells, activated CD79a+ B cells, antigen-presenting CD74+ dendritic and B cells, and PD-L1+ and PD-L2+ myeloid-derived suppressor cells (MDSCs). The oral microbiota composition differed significantly in mice bearing tongue tumors and treated with anti-PD-1. A higher abundance of Allobaculum, Blautia, Faecalibacterium, Dorea, or Roseburia was associated with response to the therapy. However, an increase in Enterococcus was attributed to tongue tumor-bearing non-responding mice. Our findings indicate that differences in immune phenotypes, protein expression, and bacterial abundance occur as mice develop tongue tumors and are treated with anti-PD-1. These results may have a clinical impact as specific bacteria and immune phenotype could serve as biomarkers for treatment response in HNSCC.

Systematic Review on the Effectiveness and Outcomes of Nivolumab Treatment Schemes in Advanced and Metastatic Cervical Cancer. Diseases 2024; 12:77. [PMID: 38667535 PMCID: PMC11049060 DOI: 10.3390/diseases12040077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Revised: 04/09/2024] [Accepted: 04/13/2024] [Indexed: 04/28/2024] Open
Abstract
Advanced and metastatic cervical cancer remains a formidable challenge in oncology, with immune checkpoint inhibitors such as the PD-1 inhibitor nivolumab emerging as a potential therapeutic option. This systematic review rigorously assesses the effectiveness and outcomes of various nivolumab treatment regimens within this patient cohort, drawing from clinical trials and real-world evidence up to December 2023. Following a comprehensive search across PubMed, Scopus, and Embase, four studies were deemed eligible, involving a collective total of 80 patients. One preliminary trial data were excluded from the final analysis, as well as four other proceedings and abstracts on the efficacy and safety of nivolumab on advanced cervical cancer. The patients' average age across these studies was 48 years, with an average of 38% having an Eastern Cooperative Oncology Group (ECOG) performance status of 1. Notably, 64% of all patients were positive for high-risk HPV, and 71% exhibited PD-L1 positivity, indicating a substantial target population for nivolumab. The analysis revealed a pooled objective response rate (ORR) of 48%, with a disease control rate (DCR) averaging 71%. Moreover, progression-free survival (PFS) at 6 months was observed at an average rate of 50%, reflecting the significant potential of nivolumab in managing advanced stages of the disease. The review highlights the influence of PD-L1 status on response rates and underscores the enhanced outcomes associated with combination therapy approaches. By delineating the variability in treatment efficacy and pinpointing key factors affecting therapeutic response and survival, this systematic review calls for further investigations to refine nivolumab's clinical application, aiming to improve patient outcomes in advanced and metastatic cervical cancer.

Abstract
Cervical cancer is one of the most common gynecological malignancies. Upregulation of programmed death ligand-1 (PD-L1), an immunoregulatory protein, is associated with an adverse outcomes in several malignancies. Most studies evaluating PD-L1 expression in cervical squamous cell carcinoma (CSCC) lack data on outcomes. In this study, we correlate PD-L1 expression with clinicopathologic factors and clinical outcomes in invasive CSCC. Seventy-three cases of CSCC from 2010 to 2018 were immunostained for PD-L1. A combined positive score (CPS) of ≥1 and ≥10 was correlated with age, stage, and survival outcomes. Kaplan-Meier curves for progression-free survival and overall survival were plotted and compared using the log-rank test. Cox regression analysis was performed to identify significant prognostic factors (2-tailed P <0.05 was considered statistically significant). With CPS ≥1 or ≥10 as the cut-off, PD-L1 was positive in 52/73 (71.2%) and 23/73 (31.5%) of cases, respectively. PD-L1 positive patients present at a higher stage of disease, especially those with CPS ≥10. With CPS of ≥10 as the cut-off, the 5-yr progression-free survival and 5-yr overall survival were significantly lower ( P = 0.034 and 0.012, respectively). Only stage was statistically significant for worse overall survival on multivariate analysis. PD-L1 positive patients present at a higher stage of disease, and stage is an independent prognostic indicator for adverse outcomes in CSCC. This study highlights the potential of PD-L1 targeted therapy in patients with CSCC.

Abstract
Cervical cancer is a serious threat to women's health globally. Therefore, identifying key molecules associated with cervical cancer progression is essential for drug development, disease monitoring, and precision therapy. Recently, TGF-β (transforming growth factor-beta) has been identified as a promising target for cervical cancer treatment. For advanced cervical cancer, TGF-β participates in tumor development by improving metastasis, stemness, drug resistance, and immune evasion. Accumulating evidence demonstrates that TGF-β blockade effectively improves the therapeutic effects, especially immunotherapy. Currently, agents targeting TGF-β and immune checkpoints such as PD-L1 have been developed and tested in clinical studies. These bispecific antibodies might have the potential as therapeutic agents for cervical cancer treatment in the future.

Serum cell division cycle 42 reflects the treatment response and survival in patients with advanced cervical cancer who receive immune checkpoint inhibitor treatment. Oncol Lett 2023; 26:414.

Abstract
Cell division cycle 42 (CDC42) regulates immune escape, which predicts immune checkpoint inhibitor (ICI) treatment response in several types of cancer. The present study aimed to evaluate the potential of serum CDC42 in predicting the ICI treatment outcome in patients with advanced cervical cancer. A total of 46 patients with advanced cervical cancer who received ICI treatment with or without antiangiogenic agents were enrolled. Serum CDC42 was detected in all patients before treatment (baseline) and following two treatment cycles by enzyme-linked immunosorbent assay. CDC42 at baseline was elevated in patients with target lesion size ≥5 cm (P=0.020), pelvis metastasis (P=0.031) and lung metastasis (P=0.043). Following treatment, the objective response rate (ORR) and disease control rate (DCR) were 30.4 and 78.3%, respectively. Meanwhile, the median progression-free survival (PFS) and overall survival (OS) were 5.8 and 13.1 months. CDC42 at baseline was decreased in patients achieving ORR (P=0.042) but not DCR (P=0.055). PFS (P=0.006) and OS (P=0.019) were decreased in patients with baseline CDC42 ≥600 pg/ml. After two treatment cycles, CDC42 was generally reduced (P<0.001). CDC42 following two treatment cycles was more significantly decreased in patients with ORR (P=0.032) and DCR (P=0.019). Multivariate Cox's regression analysis showed that CDC42 ≥600 pg/ml following two treatment cycles was associated with the shorter PFS (P=0.022, hazard ratio=2.469) and OS (P=0.013, hazard ratio=4.166). Serum CDC42 was reduced after treatment; high expression following treatment reflected a lower possibility of achieving treatment response and poorer survival in patients with advanced cervical cancer.

Gynecol Oncol Rep 2023; 48:101244.

Abstract
Immune checkpoint inhibitors (ICI) were approved in June 2018 for second line treatment of metastatic cervical cancer after progression on platinum-based chemotherapy. A cohort of 10 patients who received single agent ICI as second line treatment was examined, with an initial analysis published in July 2021. We performed an updated review of the duration of treatment response, outcome off treatment after 2 years of therapy, and outcome after re-initiation of ICI. Excluding 4 patients from the original report who subsequently experienced progression of disease and/or death, 6 patients were followed for 40 months (range, 39.2-50.8 months), and all achieved complete response (CR) as their best response after prolonged treatment, including 3 with initial partial response (PR). Four patients discontinued treatment, and two developed asymptomatic recurrence, were both re-initiated on ICI, and reached a CR and PR. The combined positive score (CPS) was variable among responders and non-responders, but levels were highest among the 2 patients off treatment who remained without evidence of disease. This update on prolonged follow up demonstrates that patients who respond to immune checkpoint inhibitors may deepen their response with prolonged treatment, have durable response off treatment and respond again to re-treatment in the event of recurrent disease. A higher CPS score may predict prolonged remission off treatment.

Abstract
The limitation of the function of antitumour immune cells is a common hallmark of cancers that enables their survival. As such, the potential of immune checkpoint inhibition (ICI) acts as a paradigm shift in the treatment of a range of cancers but has not yet been fully capitalised. Combining minimally and non-invasive locoregional therapies offered by radiologists with ICI is now an active field of research with the aim of furthering therapeutic capabilities in medical oncology. In parallel to this impending advancement, the "imaging toolbox" available to radiologists is also growing, enabling more refined tumour characterisation as well as greater accuracy in evaluating responses to therapy. Options range from metabolite labelling to cellular localisation to immune checkpoint screening. It is foreseeable that these novel imaging techniques will be integrated into personalised treatment algorithms. This growth in the field must include updating the current standardised imaging criteria to ensure they are fit for purpose. Such criteria is crucial to both appropriately guide clinical decision-making regarding next steps of treatment, but also provide reliable prognosis. Quantitative approaches to these novel imaging techniques are also already being investigated to further optimise personalised therapeutic decision-making. The therapeutic potential of specific ICIs and locoregional therapies could be determined before administration thus limiting unnecessary side-effects whilst maintaining efficacy. Several radiological aspects of oncological care are advancing simultaneously. Therefore, it is essential that each development is assessed for clinical use and optimised to ensure the best treatment decisions are being offered to the patient. In this review, we discuss state of the art advances in novel functional imaging techniques in the field of immuno-oncology both pre-clinically and clinically.

Abstract
Background Programmed death-ligand-1 (PD-L1) molecule is a well-known predictive biomarker for the efficacy of immune checkpoint inhibitors (ICIs) in several cancers. Present systematic review and meta-analysis aimed at investigating the role of PD-L1 in predicting the effectiveness of programmed death-1 (PD-1)/PD-L1 inhibitors in patients suffering from esophageal cancer. Methods We searched PubMed, Scopus, Web of Science, and EMBASE databases as of March 25, 2022, for retrieving the potential relevant randomized controlled trials (RCTs). The pooled hazard ratios (HR) and the corresponding 95% confidence intervals (95%CIs) were calculated for the outcomes of overall survival (OS) and progression-free survival (PFS). The primary objective was to investigate the association between PD-1/PD-L1 inhibitors vs. control agents and treatment efficacy in terms of OS in patients with esophageal tumor expressing different values of PD-L1 based on combined-positive score (CPS) and tumor proportion score (TPS). The secondary outcome was the pooled risk of PFS. Results Eleven studies with a total of 5,418 participants were included. While there was no difference in the OS of CPS<1 patients in the intervention and the control group, patients bearing esophageal tumors with a CPS≥1 (HR 0.65, 0.56-0.74) treated by ICIs showed a significant improvement in OS relative to the control agents. Accordingly, patients with CPS<5 (HR 0.75, 0.58-0.98), CPS≥5 (HR 0.64, 0.53-0.77), CPS<10 (HR 0.86, 0.76-0.98), and CPS≥10 (HR 0.65, 0.56-0.75) had improved OS; however, a significant longer OS was observed in cases who expressed higher values of CPS=10 (p=0.018). In terms of TPS, a significant greater benefit in prolonging the OS came from TPS≥1% PD-L1 expressing tumors in comparison to TPS<1% tumors, suggesting this cut-off as another predictor of PD-1/PD-L1 inhibitors efficacy. Notably, in the subgroup analysis when the cut-off value of CPS=10 or TPS=1% was selected, Nivolumab was the best ICI that improved the survival of PD-L1 positive patients. In patients with negative PD-L1 expression, Toripalimib is the only ICI which could prolong the OS of patients with the cut-off value of CPS=10. Conclusion Among patients suffering from esophageal cancer, PD-L1 CPS=10 and TPS=1% expression thresholds seem to be predictive of a lower rate of mortality when PD-1/PD-L1 inhibitors are administrated; however, further large-scale trials are required for confirming the findings of the present study.

Abstract
Most cervical cancer patients are prone to developing acquired cisplatin (DDP) resistance. Hsa_circ_0074269 (circ_0074269) plays a promoting role in cervical cancer, but whether circ_0074269 mediates cervical cancer resistance to DDP is unclear. Expression of circ_0074269 was detected by real-time quantitative polymerase chain reaction (RT-qPCR). The half-maximal inhibitory concentration (IC50) value, viability, proliferation, colony formation, migration, and apoptosis of DDP-resistant cervical cancer cells were determined. The molecular mechanisms associated with circ_0074269 were predicted by bioinformatics analysis and confirmed by dual-luciferase reporter and RIP assays. Xenograft assay was conducted to validate the effect of circ_0074269 on DDP resistance in vivo. Exosomes were isolated by ultracentrifugation. Circ_0074269 was overexpressed in DDP-resistant cervical cancer samples and cells. Silencing of circ_0074269 elevated DDP sensitivity, repressed DDP-resistant cervical cancer cell proliferation, and induced DDP-resistant cervical cancer cell apoptosis in vivo and in vitro and curbed DDP-resistant cervical cancer cell migration in vitro. And circ_0074269 could regulate DDP resistance via regulating TUFT1 expression via sponging miR-485-5p. More strikingly, circ_0074269 was also overexpressed in exosomes from DDP-resistant cervical cancer cells, and circ_0074269 could be delivered via exosomes. Circ_0074269 facilitated DDP resistance via elevating TUFT1 expression via sponging miR-485-5p, proving novel evidence to offer circ_0074269 as a target for cervical cancer treatment.
