Thymic carcinomas are rare aggressive cancers with limited clinical trial data. Its usual treatment is surgical resection with variable response to chemotherapy and radiation. It usually presents as anterior mediastinal mass with late sequela of metastases to the lymph nodes, pleura and bones. We present of thymic carcinoma with a rare initial presentation of vertebral metastases causing spinal cord compression.

BACKGROUND: Carcinoma showing thymus-like elements (CASTLE) is a rare tumor that normally affects the thyroid gland and was thought to arise from either the remnants of the branchial pouch or the ectopic cervical thymic tissue. These tumors show strong immunopositivity for CD5, P63, and CD117. Most CASTLE of the thyroid gland is treated with surgery with or without adjuvant radiotherapy or chemotherapy. METHOD: A 55-year-old woman presented with a slow-growing right parotid mass...

Carcinoma showing thymus-like differentiation of the thyroid (CASTLE) is a rare tumor involving the thyroid and perithyroidal soft tissues. It shares morphological, immunohistochemical and molecular similarities with thymic carcinomas. Due to its relatively better prognosis, it needs differentiation from other primary and metastatic tumors of this region. A 40-year-old lady presented with a gradually progressive anterior neck swelling for one year. Imaging showed bulky right and left lobes of thyroid along with a solid soft tissue mass in the pretracheal region...

Neuroendocrine tumors of the thymus (NETTs) are rare but aggressive, and lead to poor overall survival. This retrospective study was designed to analyze factors that correlate with the prognosis of patients with NETTs.From 1999 to 2015, 41 ongoing patients with NETTs were enrolled in this study. The clinical data and outcome were compiled. Overall survival (OS) rate was analyzed using the Kaplan-Meier method in univariate analysis and the Cox-model was used in multivariate analysis.Of the 41 NETTs patients analyzed (31 male and 10 female), 12 were typical carcinoma, 14 were atypical carcinoma, 14 were small-cell carcinoma and, 1 was large-cell carcinoma...

PURPOSE: The preoperative peripheral neutrophil-to-lymphocyte ratio (NLR) is associated with a poor prognosis for various cancers. We evaluated the prognostic role of the preoperative NLR in patients with thymoma. METHODS: We reviewed the medical records of 254 patients who underwent resection of thymic epithelial tumors at our institution. Patients were excluded if they had received steroid therapy, neoadjuvant therapy, or incomplete resection, or if they had thymic carcinoma or Good's syndrome, recurrence of thymoma, or missing data...

Stereotactic body radiation therapy (SBRT) is an important modality in treatment of tumors. We hypothesized that SBRT can achieve excellent local control with limited toxicity in patients with thymic tumors. A single-institution prospective study was performed with 32 patients who underwent SBRT of thymoma and thymic carcinoma between 2005 and 2014. Thirty-two patients including 39 target lesions were analyses in this study. Almost half of the patients (46.9%) were type C by histopathology and more than half (56...

Tumours show an increased interstitial fluid pressure, which correlates with various pathophysiological features. Moreover, interstitial fluid pressure is a prognostic factor for cervical and lung cancer. However, there have been no reports on the usefulness of measuring interstitial fluid pressure in thymic epithelial tumours. Therefore, this study aimed to examine the relationship between interstitial fluid pressure and the clinicopathological characteristics of thymic epithelial tumours. Interstitial fluid pressure was prospectively measured at the centre of the tumour using a 1-Fr Mikro-Tip sensor catheter in 44 patients with thymic epithelial tumours, 40 with thymomas and 4 with thymic carcinomas...

Photochemical internalization (PCI) is a technology to enhance intracellular drug delivery by light-induced translocation of endocytosed therapeutics into the cytosol. The aim of this study was to explore the efficacy of PCI-based delivery of bleomycin and the impact on systemic anti-tumor immunity. Mouse colon carcinoma cells (CT26.CL25), stably expressing the bacterial β-galactosidase, were inoculated into the legs of athymic or immuno-competent BALB/c mice strains. The mice were injected with the photosensitizer AlPcS2a and bleomycin (BLM) prior to tumor light exposure from a 670nm diode laser...

Thymic carcinomas arise from the epithelial cells of the thymus gland and are the most common tumors of the anterior mediastinum despite their overall rarity. Because of their rarity, their treatment remains a challenging topic. Although historically they have been treated surgically, radiation therapy (RT) has an important role either as a definitive or as a postoperative treatment. In this article, we present a review of the current therapies for the thymic carcinomas and try to identify the exact place of the RT in the optimal management of these patients...

Thymic carcinoma (TC) is a rare cancer whose genomic features have been examined in only a limited number of patients of European descent. Here, we characterized both genomic and epigenomic aberrations by whole exome sequencing, RNA sequencing, methylation array and copy number analyses in TCs from Asian patients and compared them with those in TCs from USA/European patients. Samples analyzed were 10 pairs of snap-frozen surgical specimens of cancerous and non-cancerous thymic tissue. All 10 cases were Japanese patients treated at the National Cancer Center Hospital, Japan, between 1994 and 2010...

Carcinoma showing thymus-like differentiation is a rare tumor of the thyroid gland, which is structurally similar to thymic tissue. Overall, it has a favorable prognosis. Radiotherapy has been shown to be an effective local treatment, but there have been reports of distant recurrence. It has been suggested that adding chemotherapy may decrease the risk of recurrence. Here, we present a case report of a patient with a large tumor and extrathyroidal extension. The patient was treated with surgery, radiotherapy, and cisplatin with acceptable toxicity...

Lymphoepithelioma-likethymic carcinoma is a rare neoplasm that presents with compressive symptoms or as an incidental radiological finding of an anterior mediastinal mass. It is an aggressive carcinoma with a high rate of invasion, metastasis and recurrence. Its diagnosis usually carries a poor prognosis largely due to propensity for late diagnosis. To date, guidance for treatment remains limited. This is a case of lymphoepithelioma-like thymic carcinoma in a young male adult who presented initially with back pain...
