18 F-FDG PET/CT in lung adenosquamous carcinoma and its correlation with clinicopathological features and prognosis

AbstractObjectiveLung adenosquamous carcinoma (ASC) is a rare histological subtype of non-small cell lung cancer (NSCLC). Due to its rarity, the studies about18F-FDG PET/CT in this kind of pulmonary tumor were quite limited. Thus, this study investigated18F-FDG PET/CT findings in ASC and its correlation with clinicopathological features and clinical outcomes.MethodsPreoperative18F-FDG PET/CT findings and parameters of maximum standard uptake value (SUVmax), metabolic tumor volume and total lesion glycolysis of primary lesion (MTV-P, TLG-P), combination of primary lesion and metastases (MTV-C, TLG-C), and clinicopathological features were retrospectively investigated in patients with ASC. Moreover, progression-free survival (PFS) was also analyzed.ResultsAll 41 patients (25 men; 16 women; age: 60  ± 7 years) had single ASC with the mean diameter of 33 ± 14 mm. Six lesions were located centrally and 35 peripherally. Serum tumor markers were abnormally increased sporadically. Twenty-two cases were at TNM stage I, 9 at II, and 10 at III. The primary tumors were FDG-avid in all cases , with the average SUVmax of 11.5  ± 6.0. SUVmax was significantly associated with tumor location, size, and TNM stage (P

ConclusionsWe find sufficient cause to suggest that the predictive clinical value of TMB should not be overstated or oversimplified. While it is readily quantified, TMB is at best a limited surrogate biomarker of immunotherapy response. The data do not support isolated use of TMB in renal cell carcinoma.

Authors: Wang J, Yang X, Han S, Zhang L Abstract Disrupted centrosome-associated family protein expression can result in the detrimental duplication of centrosomes, causing genomic instability and subsequent carcinogenesis. Limited research has demonstrated that centrosomal protein 131 (CEP131) exhibits oncogenic activity in osteosarcoma, hepatocellular carcinoma and breast cancer. The present study demonstrated that there is an association between CEP131 expression and advanced Tumor-Node-Metastasis stage (P=0.016), and positive regional lymph node metastasis (P=0.023) in 91 cases of non-small cell lung cancer. A5...

In conclusion, the present study revealed that the upregulation of RBM47 accelerated the malignant progression of NSCLC, indicating that RBM47 may be a potential biomarker for NSCLC progression and a therapeutic target for NSCLC. PMID: 32218862 [PubMed - as supplied by publisher]

Authors: Yu G, Zhong N, Huang B, Mi Y Abstract Previous studies have suggested increased activity of phosphatidylethanolamine binding protein 4 (PEBP4) may be associated with the prognosis of non-small cell lung cancer. However, to the best of our knowledge, no direct association between PEBP4 and lung squamous cell carcinoma (LSCC) has been reported. In the present study, a systematic review and meta-analysis was performed to examine the gene expression activity of PEBP4 in LSCC. A total of 10 out of 131 gene expression datasets from the Gene Expression Omnibus (GEO) were selected, including 574 samples (319 patie...

Abstract Non-small cell lung cancer (NSCLC) is one of the most common causes of tumor-associated mortality worldwide. Early diagnosis is the key focus for improving prognosis. In the present study, the association between exhaled breath condensate (EBC) let-7 and NSCLC diagnosis and clinicopathologic characteristics was investigated in order to explore non-invasive simple technological therapeutic methods. The expression levels of let-7 from 180 samples were analyzed using the reverse transcription-quantitative polymerase chain reaction (RT-qPCR), consisting of 30 patients with NSCLC (lung cancer and para-carcinom...

Conclusions: Despite low accrual, majority of subjects treated with metformin had metabolic responses by PERCIST criteria on PET imaging. Contrary to the effect of metformin on most physiologic tissues, most tumors had increased metabolic activity in response to metformin.

AbstractPurposePrimary tumor (PT) and metastatic lymph node (MLN) status have a great influence on diagnosis and treatment of lung cancer. Our main purpose was to investigate the imaging characteristics of PT or MLN by applying the18F-FDG PET dynamic modeling approach for non-small cell lung cancer (NSCLC).MethodsDynamic18F-FDG PET scans were performed for 76 lung cancer patients, and 62 NSCLC cases were finally included in this study: 37 with newly diagnosed early and locally advanced lung cancer without distant metastases (group M0) and 25 metastatic lung cancer (group M1). Patlak graphic analysis (Ki calculation) based ...

Somatic alterations in the epidermal growth factor receptor gene (EGFR) result in aberrant activation of kinase signaling and occur in ∼15% of non-small cell lung cancers (NSCLC). Patients diagnosed with EGFR-mutant NSCLC have good initial clinical response to EGFR tyrosine kinase inhibitors (EGFR TKIs), yet tumor recurrence is common and quick to develop. Mechanisms of acquired resistance to EGFR TKIs have been studied extensively over the past decade. Great progress has been made in understanding two major routes of therapeutic failure: additional genomic alterations in the EGFR gene and activation of alternative kin...

In this study, we investigated the utility of miR-3692-3p, miR-3195, and miR-1249-3p as biomarkers in non-small cell lung cancer (NSCLC). For this prospective study, 115 subjects, including 75 NSCLC patients and 40 controls, were recruited. The expression of miR-3692-3p, miR-3195, and miR-1249-3p was checked using qRT-PCR. The miRNA expression was correlated with survival outcome and therapeutic response. There were no significant differences in the mean age of NSCLC patients and controls (56.2 and 55.3  years, respectively;p = 0.3242). Majority of NSCLC patients (67%) were smokers. We observed a signifi...
