S ‐1 plus cisplatin with concurrent radiotherapy for locally advanced thymic carcinoma: Study protocol of LOGIK1605/JART‐1501

Thymic carcinoma is a rare epithelial tumor of the thymus with a poor prognosis, and multimodal approaches are important for its treatment. Recently, a number of studies have indicated that S ‐1 treatment is effective against thymic carcinoma. S‐1 plus cisplatin with concurrent radiotherapy is a commonly used treatment for other malignancies, including non‐small cell lung cancer (NSCLC). In addition, its safety has been confirmed, and it has been reported to have a marked effect ag ainst thymic carcinoma. Therefore, we conducted a phase II study of S‐1 plus cisplatin with concurrent thoracic radiotherapy for locally advanced thymic carcinoma, in which the overall response rate was employed as the primary endpoint. The secondary endpoints were overall survival, progression‐ free survival, and safety.

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...

This study assesses the hypothesis that KRAS mutation directly regulates PD-L1 expression through the MEK-ERK pathway mediated by FRA1. Premalignant human bronchial epithelial cell (HBEC) lines harboring the KRAS mutationV12, EGFR mutation, p53 knock-down, or both KRAS mutation and p53 knock-down were tested for levels of PD-L1, FRA1, and ERK activation (pERK). Our results showed that KRAS mutation alone, but not other genetic alterations, induced significantly higher expression of PD-L1 compared to its vector counterparts. The increased PD-L1 expression in the KRAS mutated cells was dramatically reduced by inhibition of E...

Conclusion PPLELC is uncommon but distinct subtype of NSCLC with unique clinicop athologic characteristics that tends to affect young nonsmoking patients, without significant predilection for sex and with strong association with Epstein-Barr virus (EBV) infection. Histology and immunohistochemistry are the main diagnostic methods. Rare or no driver gene mutations were found in t he common oncogenes such as EGFR mutations and ALK gene rearrangement, implying that the mutagenesis of these genes was not involved in the tumorigenesis of PPLELC. PD-1 and PD-L1 may be potential therapeutic targets for PPLELC. The patients a...

Krüppel-like factor 4 (KLF4) is a transcription factor and plays a vital role in cancer initiation and development. However, the role of Krüppel-like factor 4 in the metastasis of non-small cell lung cancer (NSCLC) is not clear. Here, we demonstrated that the expression of Krüppel-like factor 4 was significantly decreased in human non-small cell lung cancer tissues compared with that in normal tissues using Western blot. We performed immunohistochemical staining and observed the decreased expression of Krüppel-like factor 4 in human lung cancer tissues, and metastatic tumor tissues located in the trache...

aacute;lez-Noya AM, Pedrido R Abstract A series of phosphino-thiosemicarbazone gold(I) dinuclear complexes obtained by two different synthetic procedures have been prepared. All the compounds have been spectroscopically characterized including single crystal X ray diffraction analysis in some of cases. [Au2(HL1)Cl2] (1), [Au2(HL2)2]Cl2 (2) and [Au2(HL3)2]Cl2 (3) have been prepared by chemical synthesis using a gold(III) salt as precursor; while [Au2(L1)2] (4), [Au2(L2)2]∙2CH3CN (5) and [Au2(L3)2] (6) have been isolated from an electrochemical synthesis (HLn = 2-[2-(diphenylphosphanyl)-benzylidene]-N-R-thiose...

Conclusions: Our study elucidate the prognostic impact of tissue AXL expression and the presence of CTCs after surgery in adenocarcinoma patients. Tissue AXL expression and CTC EMT activation could potentially represent biomarkers for the stratification of ADC patients that might benefit from new adjuvant therapies.

Abstract Over the past decades, studies of phytochemicals as modifiers of radiotherapeutic efficacy have become increasingly popular to improve the treatment outcome of human malignancies. In the current comprehensive review article, radiosensitizing effects of curcumin, a yellow-colored polyphenolic constituent of turmeric, in various preclinical cancer models, both In Vitro and In Vivo, are presented. Attenuation of radioadaptation and augmentation of irradiation-induced cancer cell killing are achieved through multifaceted action of curcumin on suppression of prosurvival and antiapoptotic factors.
