Abstract

To find serum tumor markers for predicting the presence of lymphatic metastasis in patients with lung adenocarcinoma, and to explore the diagnostic value of IGFBP7 in predicting if lymphatic metastasis occurs in lung adenocarcinoma. The concentration of IGFBP7 in the peripheral blood of 90 serum samples, including 30 patients with lung adenocarcinoma in situ, 30 patients with lung adenocarcinoma metastasis, and 30 normal controls were detected by ELISA. The data were analyzed statistically. The concentration of IGFBP7 and D-dimer in the metastatic lung adenocarcinoma group was significantly higher than that in the lung adenocarcinoma in situ group (P < 0.05). The expression level of IGFBP7 in serum of patients with lung adenocarcinoma was associated with the clinical stage (P < 0.05) and lymphatic metastasis (P < 0.05). Using the receiver operating characteristic (ROC) curve, the area under the ROC curve of IGFBP7 was 0.901 (95% Confidence Interval was 0.806 to 0.996), and 0.5 was outside the 95% confidence interval (P < 0.05). The difference was statistically significant. IGFBP7 can predict if the lung adenocarcinoma has lymphatic metastasis, which is helpful to improve the treatment of lung adenocarcinoma, and can be used as ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
