N2 - We studied Fas/FasL, Bcl-2, and M30 CytoDeath in five cases of normal thymus and 41 cases of thymic epithelial tumors (TETs). In normal thymus, Fas was expressed in all epithelial cells, but not in thymic lymphocytes; FasL was weakly expressed only in medullary epithelium and Hassals corpuscles. In TETs, Fas was expressed in all epithelial cells and lymphocytes, while FasL was differently expressed in epithelial cells of different subtypes of TETs, i.e., type A (2/2), AB (12/12), B1 (0/9), B1/B2 (0/3), B2 (0/1), B2/B3 (1/3), B3 (6/10) and C (1/1), but not in lymphocytes. Bcl2 protein was strongly expressed in medullary-derived lymphocytes of normal thymus and TETs, and weakly expressed only in medullary (spindle) epithelium of TETs. On M30 CytoDeath immunostaining, apoptotic indices were very low in all TETs (0-1.2). In ...

To gain further insight into the biology of thymic tumors, we did a comprehensive molecular analysis of 45 resected thymic tumors. To our knowledge, this study represents one of the first and largest of its kind. Previous studies have focused on only a small number of tumors (29) and used only a limited number of analytic methods (29-31). Our analysis has three main new findings.. First, mutational analysis of genes encoding components of the EGFR signaling pathway led to the identification of RAS mutations in 3 (7%) of 45 thymic epithelial tumors. Previously, investigators have collectively assessed the status of only one RAS gene (i.e., KRAS) in 17 tumors (16, 32, 33) but did not identify any mutation. In our study, two RAS mutant tumors were thymomas (type A and B2) that are low grade, and the other tumor was a thymic carcinoma that is high grade. KRAS mutations predict for primary resistance to anti-EGFR directed therapies [i.e., gefitinib/erlotinib in lung cancer (34) and cetuximab in colon ...

Overview Masses in the anterior mediastinum include neoplasms (e.g., thymomas, lymphomas, thymic carcinomas, thymic carcinoids, thymolipomas, germ cell tumors, parathyroid adenomas) or nonneoplastic conditions (e.g., intrathoracic goiter, thymic cysts, lymphangiomas, aortic aneurysms).1,2 Thymomas are the most common tumor in the anterior mediastinum.1,3,4 Many mediastinal masses are benign, especially those occurring in asymptomatic patients; however, symptomatic patients often have malignant mediastinal lesions. These guidelines outline the evaluation, treatment, and management of thymomas and thymic carcinomas (see Thymic Masses, opposite column). The WHO histologic classification system can be used to distinguish among thymomas, thymic carcinomas, and thymic carcinoids.3 Lymphomas typically manifest as generalized disease but can also be primary anterior mediastinal lesions (i.e., nodular sclerosing Hodgkin disease and non-Hodgkins lymphomas [large B-cell lymphoma and lymphoblastic ...
Recent work with immunotherapy has shown promising results with treatment of several solid malignancies, and there are several reports of good systemic responses with the combination of immunotherapy and radiation therapy (RT), most notably in advanced melanoma. Given the rapid increase in the use of checkpoint blockade as well as anti-tumor vaccines, we review here the preclinical rationale and ongoing clinical work in combining immunotherapy with RT for small cell lung cancer (SCLC) and thymic tumors. While there are several reports of promising results with the combination of immunotherapy and conventional systemic treatment, we focus here on the ongoing clinical studies that combine immunotherapy with RT, and highlight the emerging data for this multimodality approach as well as key preclinical and clinical issues that remain to be addressed. With regards to SCLC, trials exploring to the combination of immunotherapy and RT are already ongoing, but clinical studies for this combination in thymoma are

A single mutation in the transcription factor GTF2I may help differentiate fast-growing cancers of the thymus that require aggressive treatment from slow-growing ones that dont require extensive therapy, according to a study published in Nature Genetics.. Conducted by researchers from Georgetown Lombardi Comprehensive Cancer Center in Washington, DC, and the NCI, the study involved thymic epithelial tumors (TET), which are subdivided into thymomas and thymic carcinomas; thymomas are further classified into types A, AB, B1, B2, and B3 based on histological features. All begin in the epithelial cells of the thymus, a lymphatic system organ where T cells mature. Together, they account for only 0.2% to 1.5% of all cancers.. "In addition to being rare, there is an insufficient characterization of the genetic abnormalities in these tumors," says the studys senior investigator Guiseppe Giaccone, MD, PhD, associate director for clinical research at Georgetown. "Having a GTF2I mutation as a marker ...
Thymic epithelial tumors (TET) are rare. Wingless and INT (WNT), NOTCH and sonic hedgehog pathway interactions between thymocytes and thymic stroma are important to thymus and T-cell development. We analyzed a thymoma tissue microarray (TMA) for glioma associated oncogene homolog 1 (GLI1), NOTCH1 and catenin (cadherin-associated protein, beta 1) (CTNNB1) expression as surrogate markers of sonic hedgehog, NOTCH and WNT pathway activity.GLI1, NOTCH1 and CTNNB1 expression were assayed in a tissue microarray of 68 TET and eight benign thymus by fluorescent immunohistochemistry (AQUA) as surrogates for activity of the sonic hedgehog, NOTCH and WNT pathways respectively.No difference in tumor GLI1 (mean 201 vs. 211, p=0.31), CTNNB1 (mean 222 vs. 306, p=0.66) or NOTCH1 expression (mean 317 vs. 325, p=0.82) was noted between thymic tumor and benign thymus.No evidence for preferential expression of GLI1, NOTCH1 or CTNNB1 was noted. High-throughput immunofluorescence using AQUA technology can help ...

The present study aimed to investigate the expression and association of the single-nucleotide polymorphism (SNP) -1637A/G in the promoter region of the T cell immunoglobulin domain and mucin domain protein-1 (Tim-1) gene in patients diagnosed with thymoma with or without myasthenia gravis (MG). The expression of Tim-1 was detected using the streptavidin peroxidase immunohistochemical staining method on tissues obtained from thymoma patients with (n=58) and without (n=62) MG. The Tim-1 gene -1637A/G polymorphism was detected using the single allele-specific primer polymerase chain reaction. The positive rate of Tim-1 expression in thymoma patients with MG was 62.1% (32/58), which was significantly higher compared with that in thymoma patients without MG (33.9%, 21/62) (P=0.002). The genotype frequencies of GG, GA and AA in the -1637A/G polymorphism were 0.7931, 0.2069 and 0, respectively, in thymoma patients with MG, and 0.6129, 0.3871 and 0, respectively, in thymoma patients without MG.

Thymolipoma is a rare anterior mediastinal tumor composed of mature adipose tissue and benign thymic tissue, and is a benign neoplasm for which complete surgical excision is curative. Literature has reported that the thymic parenchyma of thymolipoma exceptionally contain myoid cells that are immunoreactive for desmin, muscle-specific actin and myoglobin. Herein, we describe a very rare case of thymolipoma with myoid cells. To the best of our knowledge, this is the sixth case of thymolipoma containing striated myoid cells in the English literature since 1972.

ABSTRACT. Background: We reported our experience with thymic carcinomas and review their clinical features, treatment strategies, and prognoses. Methods: From April 1998 to November 2012, 11 patients pathologically diagnosed with thymic carcinoma and treated in our hospital were investigated. Results: There were 7 men and 4 women, with a median age of 62 years (range, 35 - 72). According to the Masaoka staging system, 3 patients had stage II, 1 stage III disease, 3 stage IVa disease and 4 stage IVb disease. Ten patients had squamous cell carcinoma, whereas 1 had large cell neuroendocrine carcinoma (LCNEC). We performed surgery or multimodality therapy including surgery as the initial therapy for 8 patients. Of the non-surgical cases, 1 patient received chemoradiotherapy and survived for over 6 years without recurrence, whereas 2 received palliative care. Three of 4 patients who underwent complete resection survived without disease recurrence, whereas only 1 patient with LCNEC survived in the ...

Introduction: Thymic malignancies represent a wide range of clinical, histological and molecular entities, with considerable heterogeneity even among tumors of the same histotype. Thymomas are rare neoplasms arising from tissue elements of the thymus and developing in the anterior mediastinum, with an annual incidence of only 0.15 cases per 100, 000 person-years. They can be associated with a variety of systemic and autoimmune disorders, such as pure red cell aplasia, pancytopenia, hypogammaglobulinemia, collagen-vascular disease, and most commonly with myasthenia gravis. Surgical resection remains the cornerstone of therapy for early-stage disease, while in advanced or recurrent forms, a multimodality approach incorporating radiation and chemotherapy is required. Platinum with anthracycline-based chemotherapy is an optimal combination for advanced thymoma. Case Report: We hereby present an interesting case of thymoma which was detected on imaging for routine health check-up and was managed successfully
Background: Mediastinal masses are relatively uncommon lesions that sometimes pose an interesting diagnostic and therapeutic problem for the clinician. Thymomas are one of the common mediastinal neoplasms and exhibit a wide spectrum of morphologic features and an unrivalled frequency of other autoimmune diseases. The great morphologic variability and heterogeneity in thymomas has rendered their histological classification difficult and highly controversial. Methods: This retrospective and descriptive study on thymoma was done in the department of pathology, Kasturba Medical College Mangalore (Manipal University), India over a period of five years from January 2006 to June 2011. Histopathology sections taken were stained with routine Hematoxylin and Eosin stains in every case. Additional stains and immunohistochemistry were done as required. Results: Total number of mediastinal lesions studied was 66, with thymomas making up 15 cases. The age range of patients with thymomas was 22 to 65 years ...
Thymomas typically occur in adults older than 40 years, and are rare in children or adolescents. Although some patients are asymptomatic, others present with chest pain, cough, or dyspnea. Thymomas are usually encapsulated. Some clinicians believe that surgical biopsy should be avoided if a resectable thymoma is strongly suspected based on clinical and radiologic features, and that a transpleural approach should be avoided during biopsy of a possible thymoma (category 2B for both). However, others feel that development of pleural metastases is most likely not the result of biopsies, because many patients who have never been biopsied have pleural disease at diagnosis. Total thymectomy and complete surgical excision are generally appropriate for most patients.6-8 Before surgery, all patients should be evaluated by radiation oncologists, surgeons, medical oncologists, diagnostic imaging specialists, and pulmonologists to determine the optimal plan of care.. Although thymomas can be locally invasive ...
Here we describe, to our knowledge, the first case where an evolution of mechanisms responsible for hypercalcemia occurred in undifferentiated thymic carcinoma and discuss specific management strategies for hypercalcemia of malignancy (HCM).|i| Case Description|/i|. We report a 26-year-old male with newly diagnosed undifferentiated thymic carcinoma associated with HCM. Osteolytic metastasis-related hypercalcemia was presumed to be the etiology of hypercalcemia that responded to intravenous hydration and bisphosphonate therapy. Subsequently, refractory hypercalcemia persisted despite the administration of bisphosphonates and denosumab indicative of refractory hypercalcemia. Elevated 1,25-dihydroxyvitamin D was noted from the second admission with hypercalcemia responding to glucocorticoid administration. A subsequent PTHrP was also elevated, further supporting multiple mechanistic evolution of HCM. The different mechanisms of HCM are summarized with the role of tailoring therapies based on the particular

The main characteristics of the patients included in this study are shown in Table 1. Tumor histology has been classified according to the World Health Organization (WHO) proposal.16 The majority of the patients received thymectomy and showed an inversion of the CD4+/CD8+ ratio. Five patients were suffering from severe immunodeficiency syndrome characterized by recurrent infections of the lower respiratory tract. Flow cytometry analyses were performed at monthly intervals in the last 6 months, showing a stable reduction of mature CD19+ peripheral cells (unique patient numbers [UPNs] 091, 157, 051, 009, 147). A marked hypogammaglobulinemia had been detected in 4 of the 5 patients, whereas 1 of them (UPN 091) had normal immunoglobulin (Ig) serum levels. On the bases of clinical signs and B lymphopenia, we classified these patients as suffering from Good syndrome. We included in the study also 2 thymoma patients with normal Ig serum levels, normal B-cell counts, and no signs of severe recurrent ...
Thymomas comprise about 1% of all mediastinal tumours and are rare in children. Typically, these tumours are aggressive, with a poor outcome. The current treatment of invasive thymoma is often multidisciplinary. We report a 16-year-old boy with invasive thymoma who was successfully treated with systemic chemotherapy, surgical resection and irradiation. The patient has been in continuous remission for 6 years without radiographic evidence of tumour recurrence.. ...

Background Thymoma and thymic carcinoma will be the most frequent subtypes of thymic epithelial tumors (TETs). Carcinoma (TC1889) cell collection. Epigenetic transcriptional legislation of miR-145-5p was analyzed by dealing with the TC1889 cell series using the HDAC inhibitor Valproic Acidity (VPA). Results Beginning with the identification of the 69-gene personal of miR-145-5p putative focus on mRNAs, whose appearance was correlated compared to that of miR-145-5p inversely, the expression was accompanied by us of a few of them in vitro upon overexpression of miR-145-5p; we observed that led to the down-regulation of the mark genes, impacting on TETs cancerous phenotype. We also discovered that VPA treatment of TC1889 cells resulted in miR-145-5p up-regulation and concomitant down-regulation of miR-145-5p focus on genes and exhibited antitumor results, as indicated with the induction of cell routine arrest and by the reduced amount of cell viability, colony forming migration and capability ...
Twenty patients with myasthenia gravis had chest radiography, conventional tomography, and computed tomography (CT) of the thorax within 1 month of thymectomy. Four of the six macroscopic tumors were detected on routine chest radiography; conventional tomography provided no additional information. CT detected all six macroscopic tumors and provided additional information that was not available by other procedures. However, 18 patients (90%) had anterior mediastinum densities on CT, which could not be distinguished preoperatively from thymic tumors. All six patients with macroscopic tumors had serum antistriational muscle antibody titers; this test was negative in 10 of 11 patients (91%) without thymoma. Chest radiography, CT of the thorax, and antistriational antibodies are the tests recommended for detection of a thymoma in patients with myasthenia gravis.. ...
