Cytologic features of the endometrial adenocarcinoma: Comparison of ThinPrep and BD surepath preparations
We compared the cytoarchitectural features used for the cytologic diagnosis of endometrial adenocarcinoma (EC) using ThinPrep® (TPS = ThinPrep Sample) and BD SurePath™ (SPS = SurePath Sample) preparations. In 20 patients, a direct endometrial sample using the Uterobrush was obtained. Nineteen cases of EA and one case of carcinosarcoma were studied. TPS and SPS were performed according to the manufacturer's recommendations. Moreover, after the TPS preparation, the residual material was also used to prepare an SPS sample (TP–SPS = ThinPrep–Surepath sample). The following points were investigated in both preparations: ...

Sinonasal teratocarcinosarcoma with intracranial extension: Case report and literature review.
We report the case of a 58-year-old white man who presented with a 1-year history of a gradually enlarging left-sided nasal mass. The patient had previously undergone endoscopic sinus surgery at another facility, and the final pathologic specimen was reported as an SNTCS with positive margins. He was then referred to our institution, where he underwent a craniofacial resection combined with endoscopic intranasal resection. Postoperatively, he received combined chemotherapy and irradiation. At 48 months of follow-up, he was alive without evidence of disease. PMID: 23288820 [PubMed - in process] (Source: Ear, Nose and Throat Journal)

Resistance exercise modulates lipid plasma profile and cytokine content in the adipose tissue of tumour-bearing rats.
Abstract Cancer cachexia is a multifactorial syndrome characterised by progressive weight loss, frequently accompanied by anorexia, sarcopenia, and chronic systemic inflammation. The white adipose tissue is markedly affected by cachexia and contributes to this syndrome throught the secretion of pro-inflammatory factors which reach the adjacent tissues and the circulation. A nonpharmacologic intervention that may attenuate cancer cachexia is chronic physical activity, but the effect of resistance training upon adipose tissue inflammation in cachexia has never been examined. For that purpose we designed a protocol in...

Energy controllable steep pulse (ECSP) treatment suppresses tumor growth in rats implanted with walker 256 carcinosarcoma cells through apoptosis and an antitumor immune response.
Abstract Electrochemotherapy has been widely used for the treatment of solid tumors, although the underlying mechanism remains unclear. We aimed to investigate the effects of energy controllable steep pulse (ECSP) on the regulation of tumor growth and apoptosis in rats implanted with Walker 256 carcinosarcoma cells. A rat tumor model was established by injection of Walker 256 carcinosarcoma cells into the inguinal area. H&E staining, transmission electron microscopy, and the TUNEL assay were used to detect apoptosis. Concanavalin A-induced lymphocyte transformation and MTT assays were used to assess lymphocyte ...

Molecular events in endometrial carcinosarcomas and the role of high mobility group AT-hook 2 in endometrial carcinogenesis
Summary: The molecular events implicated in the development of endometrial carcinosarcoma remain poorly understood. Using complementary DNA microarrays, we analyzed a group of 15 endometrial carcinosarcomas and compared their gene expression profiles with those obtained from a group of 23 endometrioid endometrial carcinomas. We demonstrated changes in the expression of genes modulating processes such as the epithelial to mesenchymal transition, muscle differentiation, the expression of cancer/testis antigens, and immune response in endometrial carcinosarcomas. The high mobility group AT-hook 2 gene is an embryonic nuclear ...

High grade serous carcinoma of the ovary with a yolk sac tumour component in a postmenopausal woman: report of an extremely rare phenomenon
High grade serous carcinoma is the most common ovarian epithelial malignancy.1 Ovarian yolk sac tumours (YST) are much more uncommon and are morphologically heterogeneous, primitive teratoid neoplasms differentiating into multiple endodermal structures.2 They almost always occur before age 30 and are extremely rare in perimenopausal and postmenopausal women. Rare examples have been reported in elderly patients, sometimes associated with an ovarian surface epithelial-stromal tumour, most commonly endometrioid adenocarcinoma but occasionally carcinosarcoma, clear cell carcinoma or a mucinous neoplasm; rarely the epithelial c...

Insights into cancer metastasis from a clinicopathologic perspective: Epithelial mesenchymal transition is not a necessary step
AbstractEpithelial‐mesenchymal transition (EMT) has been implicated as the critical event initiating cancer invasion and metastasis. After disseminating through the circulation, the malignant cells have been proposed to undergo subsequent mesenchymal‐epithelial transition (MET) to form secondary tumours. However, strong evidence from human tumour specimens for this paradigm is lacking. In carcinomas, cancers derived from epithelial tissues, epithelial morphology and gene expression are almost always retained to some degree. While mesenchymal transdifferentiation may be involved in the pathogenesis of carcinosarcomas, e...

Use of mutation profiles to refine the classification of endometrial carcinomas
AbstractThe classification of endometrial carcinomas is based on pathological assessment of tumour cell type; the different cell types (endometrioid, serous, carcinosarcoma, mixed, undifferentiated and clear cell) are associated with distinct molecular alterations. This current classification system for high‐grade subtypes, in particular the distinction between high‐grade endometrioid (EEC‐3) and serous carcinomas (ESC), is limited in its reproducibility and prognostic abilities. Therefore, a search for specific molecular classifiers to improve endometrial carcinoma subclassification is warranted. We performed target...

Epithelial to mesenchymal transition in the pathogenesis of uterine malignant mixed Müllerian tumours: the role of ubiquitin proteasome system and therapeutic opportunities
Abstract Malignant mixed Müllerian tumours (malignant mixed mesodermal tumours, MMMT) of the uterus are metaplastic carcinomas with a sarcomatous component and thus they are also called carcinosarcomas. It has now been accepted that the sarcomatous component is derived from epithelial elements that have undergone metaplasia. The process that produces this metaplasia is epithelial to mesenchymal transition (EMT), which has recently been described as a neoplasia-associated programme shared with embryonic development and enabling neoplastic cells to move and metastasise. The ubiquitin proteasome system (UPS) r...

In contrast, carcinosarcoma of the gallbladder is an extremely atypical subset of gallbladder malignancies. It is characterized by the presence of both epithelial and mesenchymal components. Currently, fewer than 100 cases have been reported in the English literature. Therefore, knowledge and experience regarding this disease are limited. Recently, we experienced two cases of gallbladder carcinosarcoma, which were diagnosed as gallbladder carcinoma based on...

A Rat Pain Model of Facial Cancer
Cancer pain is a very severe problem for patients with advanced or terminal cancer. However, the induction mechanism remains unknown. Orofacial cancer patients often report difficulties in eating and swallowing, different from patients with cancer in other regions. Although several cancer pain animal models have been reported, these models have focused on the sciatic nerve areas.

Malignant Transformation in Mature Cystic Teratoma of the Ovary: Three Cases Mimicking Primary Ovarian Epithelial Tumors
This study reports 3 unusual cases of malignant transformation in mature cystic teratoma of the ovary (dermoid cyst), namely carcinosarcoma, atypical choroid plexus papilloma, and papillary thyroid carcinoma, the last case involving both ovaries and with peritoneal dissemination. Adequate sampling is essential in such ovarian tumors to establish their teratomatous origin and avoid an erroneous diagnosis of primary ovarian or metastatic tumors. The authors present the clinicopathological findings in these 3 cases with a review of literature. (Source: International Journal of Surgical Pathology)
