Thymomas are enigmatic tumors for which surgical resection is the mainstay of treatment. However, there are still many debates about resected thymomas with pleural recurrence. Repetitive operations for thymomas involving pleural recurrence are still the treatment of choice. Herein, we present a case with a suitable performance status for re-operation with a new application for argon beam coagulation. Both our experience and the currently available evidence suggest that surgical resection could be considered for patients with advanced thymomas, even for patients with locally advanced or Masaoka-Koga stage IV thymomas...

Progressive encephalomyelitis with rigidity and myoclonus (PERM) is an autoimmune disorder involving the brainstem and spinal cord and is sometimes associated with thymoma. We encountered a 75-year-old woman with typical PERM features, glycine receptor antibody, and thymoma. Her neurologic symptoms improved after thymectomy, but she unexpectedly developed anasarca with massive pleural effusions and hypoalbuminemia and finally succumbed to death. The autopsy showed edema and mononuclear infiltration in the pleura but no neuropathological findings typical of PERM...

Good's syndrome is a rare condition of immunodeficiency that is characterized by thymoma and hypogammaglobulinemia. A 74-year-old Japanese woman underwent total thymothymectomy for type AB thymoma (2015 WHO classification). She developed recurrent infectious diseases caused by Escherichia coli (bacteremia), Streptococcus pneumoniae (pneumonia and bacteremia) and Pseudomonas aeruginosa (bacteremia) in the year after thymectomy. The serum levels of immunoglobulin were significantly low (IgG 157mg/dL), which suggested that her infectious diseases were associated with Good's syndrome...

Thymomas are exceedingly rare tumours of the anterior mediastinum in children. An early awareness helps timely surgical intervention. Thymomas can occasionally be extremely aggressive. The loss of contour on chest X-Ray, to be confirmed as a large anterior mediastinal mass at computerised tomography, serves identification of a typical bilobed thymic tumour.

The developmental competence of invitro maturation (IVM) oocytes can be enhanced by antioxidant agents. The present study investigated, for the first time in the rabbit model, the effect of adding α-tocopherol (0, 100, 200 and 400µM) during IVM on putative transcripts involved in antioxidant defence (superoxide dismutase 2, mitochondrial (SOD2), glutathione peroxidase 1 (GPX1), catalase (CAT)), cell cycle regulation and apoptosis cascade (apoptosis tumour protein 53 (TP53), caspase 3, apoptosis-related cysteine protease (CASP3)), cell cycle progression (cellular cycle V-Akt murine thymoma viral oncogene homologue 1 (AKT1)), cumulus expansion (gap junction protein, alpha 1, 43 kDa (GJA1) and prostaglandin-endoperoxide synthase 2 (prostaglandin G/H synthase and cyclo-oxygenase) (PTGS2)) and metabolism (glucose-6-phosphate dehydrogenase (G6PD))...

OBJECTIVES: The association of myasthenia gravis (MG) and inflammatory myositis (IM) is rare and typically only one of the diseases is present. The management of the 2 diseases differs, therefore it is important to recognize the concomitant presentation. Here, we report a case series of 7 patients with co-existing MG and IM with review of the literature. METHOD: We identified 7 patients with concurrent MG and IM who were followed at the Neuromuscular Disease Program at a tertiary referral center in Vancouver, British Columbia from 2004 to 2017...

Thymoma and thymic carcinoma, known as the most common features of thymic epithelial tumors (TETs), are thoracic malignancies displaying varied clinical features and prognosis. These neoplasms being frequently ineligible for surgical complete resection as a curative treatment because of extensive tumor spread, effectual nonsurgical treatments are needed; however, an optimal chemotherapeutic regimen has not been identified, although some regimens have been shown to be active. Immunotherapy is effective for other malignancies and may be promising as a therapeutic alternative for refractory TETs...

Purpose: Receptor tyrosine kinase inhibitors (RTKIs) are used as targeted therapies for patients diagnosed with cancer with highly expressed receptor tyrosine kinases (RTKs), including the platelet-derived growth factor receptor (PDGFR) and c-Kit receptor. Resistance to targeted therapies is partially due to the activation of alternative pro-survival signaling pathways, including cyclooxygenase (COX)-2. In this study, we validated the effects of two RTKIs, axitinib and AB1010, in combination with COX inhibitors on the V-akt murine thymoma oncogene homolog 1 (Akt) and COX-2 signaling pathways in bladder cancer cells...
