Thymic Carcinoma With Endobronchial Metastasis: A Case Report

Thymic carcinoma is a rare cancer, accounting for only 1% to 4% of thymic epithelial tumors. Endobronchial metastasis is a rare presentation of these tumors. A 64-year-old man presented with a cough. Lung cancer was suspected because a chest radiograph showed a 7-cm mass in the left pulmonary hilum. Computed tomography showed a mass in the anterior mediastinum and an infiltrate in the upper lobe of the left lung. Bronchoscopy demonstrated bilateral polypoid tumors in the left B3 bronchus and the right B1 bronchus. Endobronchial biopsies of both lesions resulted in a diagnosis of squamous cell carcinoma that was positive for c-KIT by immunohistochemical staining. The patient was eventually found to have thymic squamous cell carcinoma with bilateral endobronchial metastases (stage IVb according to the Masaoka-Koga staging system) by diagnostic video-assisted thoracoscopic surgery. He was subsequently treated with platinum-doublet chemotherapy and achieved a partial response for 18.8 months.

Conclusions: The abnormal location of FLT3 caused by different glycosylation status leads to the distinguishing signaling pathways. Targeting on FLT3 glycosylation may provide a new perspective for therapeutic strategies.

Authors: Yoo JJ, Yu SJ, Lee B, Cho EJ, Lee JH, Kim SG, Kim YJ, Kim YS, Yoon JH Abstract Background/Aims: Patients with an intermediate stage of hepatocellular carcinoma (HCC) represent a highly heterogeneous population; therefore, many models have been proposed to predict the survival of these patients. The aim of this study was to evaluate the prognostic performance of a novel subclassification for tumors classified as Barcelona Clinic Liver Cancer (BCLC) stage B using the Model to Estimate Survival in Ambulatory HCC patients (MESIAH). Methods: This analysis was based on 377 patients with HCC treated at Seoul ...

This study enrolled 2,940 subjects, including patients with GC (n=1,124) or gastric dysplasia (n=353) and controls (n=1,463). Tests to determine sPG levels and Helicobacter pylori (HP) infection status were performed. Area under the curve and receiver operating characteristic curve were calculated to identify the optimal cutoff values for sPG. The usefulness of sPG levels for the detection of GC and gastric dysplasia was validated by multivariate logistic regression. Results: The sPGI/II ratio was associated with the risk of gastric dysplasia and advanced-stage intestinal-type GC (IGC). In contrast, sPGII was associate...

Authors: Ichihara E, Miyahara N, Maeda Y, Kiura K Abstract Systemic therapy for advanced non-small cell lung cancer (NSCLC) has dramatically changed in the latest 15 years. Molecular-targeted therapy has brought about an era of precision medicine, and immune checkpoint inhibitors have brought hope for a cure for advanced NSCLC. In the wake of this remarkable advancement, lung cancer with comorbid interstitial pneumonia (IP) has been completely left behind, as most clinical trials exclude patients with comorbid IP. IP, especially idiopathic pulmonary fibrosis (IPF), is often accompanied by lung cancer, and acute exa...

We describe the case of a 52-year-old female outpatient who developed OIC while receiving oxycodone for pain due to cancer with multiple bone metastases. Although she did not have brain metastasis, opioid withdrawal syndrome (OWS) developed after taking naldemedine orally. Her Clinical Opiate-Withdrawal Score (COWS) was 19 (moderate symptoms). However, she recovered from OWS on intravenous fentanyl and a continuous infusion of oxycodone. She did not develop OWS thereafter and was discharged two days after recovery.

Authors: Hotta T, Okimoto T, Hamaguchi M, Tsubata Y, Isobe T Abstract A 40-year-old Japanese man with advanced pulmonary adenocarcinoma harboring anaplastic lymphoma kinase (ALK)-rearranged was administered the selective ALK inhibitor ceritinib as a third-line treatment and continued treatment for nine months. After fourth-line treatment, we performed rechallenge with ceritinib as a fifth-line treatment. On day 54 after rechallenge, the patient developed acutely deteriorating dyspnea. Chest computed tomography showed extensive ground-glass opacities. We diagnosed him with ceritinib-induced interstitial lung disease...

Abstract Nephronophthisis (NPHP) is an autosomal recessive cystic kidney disease that is characterized by primary ciliary dysfunction (ciliopathy) and progresses to end-stage kidney disease (ESKD) during the second decade of life (juvenile and adolescent NPHP) or before the age of 3 years (infantile NPHP). Here we describe the case of an infant with NPHP who carries a homozygous mutation in SDCCAG8 (also called NPHP10 or BBS16) that encodes SDCCAG8 (serologically defined colon cancer antigen 8). SDCCAG8 is localized at the centrioles of both renal epithelial cells and retinal photoreceptor cells. A mutation in SDC...

ConclusionsEGCG can be used for cancer treatment. It increases the potency of several chemotherapeutics such as doxorubicin, cisplatin, and tamoxifen, in vivo and in vitro, in many cancers. MDR reversal by EGCG is facilitated by a plethora of mechanisms including oxidative and antioxidative responses, altered cell death and survival responses, suppression of oncogenic transcription factors, modulating the tumor microenvironment, and regulating multiple signal transduction pathways.
