Real ‐world data on EGFR/ALK gene status and first‐line targeted therapy rate in newly diagnosed advanced non‐small cell lung cancer patients in Northern China: A prospective observational study

BackgroundTyrosine kinase inhibitors (TKIs) can significantly prolong overall survival for patients with advanced non ‐small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) ‐mutation or anaplastic lymphoma kinase (ALK) ‐rearrangement. However, the real‐world evaluation status of ALK/EGFR in China remains unclear.MethodsWe conducted a prospective study including 1134 patients with cytologically or histologically confirmed advanced NSCLC (stage IIIb –IV) at 12 Chinese hospitals.ResultsThe most common evaluation methods were amplification ‐refractory mutation system forEGFR status and immunohistochemistry targeting D5F3 forALK status. Among patients with non ‐squamous, theEGFR mutation rate was 44.1% and theALK rearrangement rate was 10.0%. Among patients with squamous cell carcinoma, theEGFR mutation rate was 8.3% and theALK rearrangement rate was 3.7%. Among all patients, gender (HR = 1.7, 95%CI = 1.2 –2.4,P = 0.006), smoking history (HR = 1.8, 95%CI = 1.3 –2.7,P = 0.001), histology (HR = 5.0, 95%CI = 2.4 –10.1,P

Authors: Vučićević Boras V, Vidović Juras D, Aurer I, Bašić-Kinda S, Mikulić M Abstract A 40-year-old female patient was admitted to the Department of Oral Medicine due to oral ulcerations. Oral ulcerations were present on vestibular mucosa above teeth 21, 22, 25 and 26 and were 1 cm in diameter, and also around teeth 45 and 46. The patient had prolonged neutropenia due to therapy-related myelodysplastic syndrome that progressed to therapy-related acute myeloid leukemia. Initially, the patient was successfully treated with polychemotherapy for non-Hodgkin lymphoma. Unfortunately, many toxic complicatio...

We report the first case in Croatia where we used LCAP in the treatment of a patient with severe steroid-dependent UC. After 12 LCAP procedures, good clinical response was obtained and there were no significant adverse side effects noticed. The patient remained in clinical remission over two years in which he underwent regular follow ups at outpatient clinic. Over a 10-year follow-up period after LCAP, the patient had only occasional clinical symptoms of disease activity. The clinical course was complicated with the development of metastatic colorectal carcinoma, which points to the importance of regular disease monitoring...

PROGNOSTIC ROLE OF CD44 EXPRESSION AND NEOVASCULARIZATION DETERMINED BY ENDOGLIN (CD105) IN GLIOBLASTOMA PATIENTS. Acta Clin Croat. 2019 Sep;58(3):455-462 Authors: Mihić J, Rotim K, Vučić M, Hude Dragičević I, Borić M, Lugović-Mihić L Abstract Glioblastoma multiforme (GBM) is the most common and most aggressive malignant primary brain tumor in humans. Clinically useful molecular markers that help predict response to therapy and prognosis are still rare. The research was conducted in 55 patients with GBM, 26 (47.3%) women and 29 (52.7%) men, mean age 62.58 years. On immunohistochemical analysis,...

MEAN PLATELET VOLUME: AN OVERLOOKED HERALD OF MALIGNANT THYROID NODULES. Acta Clin Croat. 2019 Sep;58(3):417-420 Authors: Sit M, Aktas G, Ozer B, Kocak MZ, Erkus E, Erkol H, Yaman S, Savli H Abstract Physicians and surgeons pay much attention to evaluating thyroid nodules due to the malignant potential of these growths. Inflammation has a crucial role in the development of cancer. Increase in the mean platelet volume (MPV) has been described in various inflammatory conditions. Since some of thyroid nodules are malignant, we aimed to compare MPV values between patients with malignant and benign thyroid ...

However, the metabolome of a coculture of A. johnsonii and P. fluorescens is still unclear. The aim of this study was to investigate the metabolomic changes in A. johnsonii, P. fluorescens, and their co-culture by screening for metabolic markers. PCA and PLS-DA revealed that A, P, and AP groups were different from each other, indicat...

In conclusion, we showed hypermethylation of CpGs as a novel mechanism of action for DNMTi agents and identified 638 hypermethylated molecular targets (CpGs) common to decitabine and azacytidine therapy. These novel results suggest that hypermethylation of CpGs should be considered when predicting the DNMTi responses and side effects in cancer patients. Introduction DNA methyltransferase inhibitors (DNMTi) are widely used as chemical tools for hypomethylating the genome, with an aim to understand the role of DNA methylation in multiple processes (e.g., X-chromosome inactivation and DNA imprinting) and as an anti-ca...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...
