Methylated PTGER4 is better than CA125, CEA, Cyfra211 and NSE as a therapeutic response assessment marker in stage IV lung cancer

Effect Evaluation of Bronchial Artery Embolization for Hemoptysis of Lung Cancer and Changes in Serum Tumor Markers and miR-34 Levels

The clinical efficacy, serum tumor markers, and miR-34 expression levels of bronchial artery embolization (BAE) in patients with lung cancer with hemoptysis are investigated. 92 patients with lung cancer hemoptysis treated in our hospital from January 2019 to December 2021 are randomly selected, and 92 patients are randomly divided into the conservative group and the BAE group according to the number table method, with 46 patients in each group. The efficacy, overall survival (OS) rate, coagulation function, hemoptysis volume, serum tumor markers, and miR-34 expression are compared among all groups at different time points. The experimental results show that the BAE treatment can promote the expression of miR-34 and inhibit the expression of tumor markers, so it can improve the efficacy of patients with lung cancer hemoptysis, improve the symptoms of hemoptysis and coagulation function, and prolong the life cycle of patients.

Analysis on the Efficacy of Bronchial Artery Chemoembolization Combined with 125I Seed Implantation in the Therapy of Advanced Non-Small-Cell Lung Cancer Based on the Medical Database

Objective

To investigate the use and the efficacy of bronchial artery chemoembolization combined with 125I seed implantation in advanced non-small-cell lung cancer (NSCLC) therapy based on the medical database.

Methods

A total of 102 patients with advanced NSCLC were randomly divided into two groups. The control group was treated with 125I seed implantation, and the observation group was treated with bronchial artery chemoembolization (BACE) combined with 125I seed implantation based on medical database. The clinical efficacy, carcinoembryonic antigen (CEA), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), glycan antigen 125 (CA125), peripheral blood CD3+, CD8+, CD4+/CD8+ T cells, insulin-like growth factor type 1 receptor (IGF-1R), S100 calcium-binding protein A2 (S100A2), long-term efficacy (time to disease progression, six-month survival rate, and one-year survival rate), and safety were then analyzed.

Result

The disease remission rate in the observation group was 62.75%, which was higher than that in the control group (41.18%). After 1 month and 3 months of treatment, the levels of serum CYFRA21-1, CEA, CA125, and IGF-1R were lower, while serum S100A2 was higher in the observation group than in the control group (P < 0.05). For safety assessment, we found that the incidences of neutropenia, thrombocytopenia, and gastrointestinal reactions had no statistical differences between two groups. The time to disease progression in the observation group was 129.85 d longer than that in the control group, 89.74 d, and the six-month survival rate and 1-year survival rate were higher in the observation group relative to the control group.

Conclusion

Medical database-based BACE combined with 125I seed implantation in the therapy of advanced NSCLC patients has definite efficacy with certain safety, which can enhance antitumor effect and prolong survival rate in advanced NSCLC patients.

Prostanoid Signaling in Cancers: Expression and Regulation Patterns of Enzymes and Receptors

Cancer-associated disturbance of prostanoid signaling provides an aberrant accumulation of prostanoids. This signaling consists of 19 target genes, encoding metabolic enzymes and G-protein-coupled receptors, and prostanoids (prostacyclin, thromboxane, and prostaglandins E2, F2α, D2, H2). The study addresses the systems biology analysis of target genes in 24 solid tumors using a data mining pipeline. We analyzed differential expression patterns of genes and proteins, promoter methylation status as well as tissue-specific master regulators and microRNAs. Tumor types were clustered into several groups according to gene expression patterns. Target genes were characterized as low mutated in tumors, with the exception of melanoma. We found at least six ubiquitin ligases and eight protein kinases that post-translationally modified the most connected proteins PTGES3 and PTGIS. Models of regulation of PTGIS and PTGIR gene expression in lung and uterine cancers were suggested. For the first time, we found associations between the patient’s overall survival rates with nine multigene transcriptomics signatures in eight tumors. Expression patterns of each of the six target genes have predictive value with respect to cytostatic therapy response. One of the consequences of the study is an assumption of prostanoid-dependent (or independent) tumor phenotypes. Thus, pharmacologic targeting the prostanoid signaling could be a probable additional anticancer strategy.

Diagnostic, Prognostic, and Recurrence Monitoring Value of Plasma CYFRA21-1 and NSE Levels in Patients With Esophageal Squamous Cell Carcinoma

This study was aimed to evaluate the clinical values of single markers and combination in the diagnosis, short-term efficacy and recurrence risk assessment of esophageal squamous cell carcinoma (ESCC).
