Human papillomavirus (HPV) type 16 is associated with the majority of OPC. Circulating antibodies (Abs) to multiple HPV16 early antigens, including E2, E6, and E7, have been detected in patient sera, and are strongly associated with risk for OPC. However, HPV serology currently requires laboratory-based tests that are difficult to implement for large-scale cancer screening.ObjectiveThe goal of this study was to develop and validate a point-of-care assay for rapid detection of circulating IgG to HPV16 early antigens.MethodsWe measured Abs to HPV16 E2, E6, and E7 proteins using a lateral flow assay (LFA) in sera from 119 newly diagnosed OPC cases, 41 partners, and 81 healthy volunteers. The 119 patients with HPV-OPC were classified as HPV-positive based on in situ hybridization (ISH) or institutional p16 immunohistochemistry. The sensitivity and specificity of the LFA were determined by comparing to clinical diagnosis.ResultsThe specificity for each individual HPV16 E2, E6, and E7 antibodies was 95.1% (77/81), 96.3% (78/81), and 98.7% (80/81), respectively. The sensitivities of the individual HPV16 antibodies were as follows: E2, 47.9% (57/119), E6, 31.9% (38/119), and E7, 57.1% (68/119). The 3-biomarker panel (at least one positive for E2, E6, and E7 Abs) demonstrated a sensitivity of 76.5% (91/119) and a specificity of 92.6% (75/81).ConclusionsWe developed a multiplexed lateral flow assay for the rapid detection of serologic responses to HPV16.

LC-derived exosomes have been found to play a critical role in tumor initiation, progression, metastasis and drug resistance. Therefore, the objective of this study is to identify prognostic markers based on lung cancer-derived exosomes in patients with different subtypes of lung cancer, including small cell lung cancer (SCLC), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC) and large cell carcinoma (LCC). Additionally, we aim to develop corresponding prognostic models to predict the outcomes of these patients. <b>Methods:</b> In this study, the mRNAs information about LC-derived exosomes was collected from Vesiclependia database, and the mRNAs data of LCC, LUAD, LUSC and LCC tumors and paracancerous tissues was obtained from the GEO database and UCSC database. The prognostic models based on exosomes-related differential expression genes (ExoDEGs) by univariate Cox, LASSO, and multivariate Cox regression analyses. The independent prognostic value of the risk model was systematically analyzed. <b>Results:</b> A LUAD prognostic risk model of 12 ExoDEGs (CDH17, DAAM2, FKBP3, FLNC, GSTM2, PGAM4, HPCAL1, FERMT2, LYPD1, SNRNP70, KIR3DL2 and GPX3) and a LUSC prognostic risk model of 7 ExoDEGs (FGA, ERH, HID1, CSNK2A1, SLC7A5, ACOT7 and FUNDC1) were constructed. Kaplan-Meier curve, ROC curve and stratification survival analysis confirmed that the LUAD and LUSC risk models both possessed reliable predictive value for the prognosis of LUAD and LUSC patients. The expression level of ExoDEGs for building the LUAD and LUSC risk models is significantly correlated with immunosuppressive activity of patients, and the immunosuppressive activity is lower in the high-risk groups. <b>Conclusions:</b> We established a LUAD prognostic model with 12 ExoDEGs and a LUSC prognostic model with 7 ExoDEGs, which can be used as independent prognostic indicators for patients LUAD and LUSC.

We found a significant correlation between RBP-based cell clusters and cancer progression. Notably, a prognostic model was constructed using RBPs such as CELF2, which showed downregulation from early leukoplakia to advanced cancer stages.

Recent advances in high-throughput technologies and machine learning have facilitated the development of blood-based multi-cancer early detection (MCED) tests. The opportunity for early detection of multiple cancers with a single blood test holds promise in addressing the current unmet need in cancer screening. By complementing existing SoC screening, MCED tests have the potential to detect a wide range of cancers at earlier stages when patients are asymptomatic, enabling more effective treatment options and improved cancer outcomes. MCED tests are positioned to be utilized as a complementary screening tool to improve screening adherence at the population level, to broaden screening availability for individuals who are not adherent with SoC screening programs, as well as for those who may harbor cancers that do not have SoC testing available. Published work to date has primarily focused on test performance relating to sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). MCED tests will require approval through the pre-market approval pathway from the United States Food and Drug Administration. Additional studies will be needed to demonstrate clinical utility (i.e., improvements in health outcomes) and establish optimal implementation strategies, (i.e., testing intervals), follow-up and logistics of shared decision making.
