BACKGROUND: Sinonasal teratocarcinosarcoma is a rare and aggressive malignancy with histological features of both carcinosarcoma and teratoma. The optimal management of this malignancy is unclear, with most patients being managed by a combination of surgery and radiotherapy. CASE PRESENTATION: We describe an 83-year-old white woman with sinonasal teratocarcinosarcoma of her left nasal cavity treated with surgical debulking initially with radiological evidence of residual disease which was treated with radiotherapy (60 Gy in 30 fractions)...

BACKGROUND: PRAME (preferentially expressed antigen in melanoma), a member of the cancer-testis antigen family, has been shown to have increased expression in solid tumors, including sarcoma, and PRAME-specific therapies are currently in development for other cancers such as melanoma. METHODS: To map the landscape of PRAME expression in sarcoma, we used publicly available data from The Cancer Genome Atlas (TCGA) and the Cancer Cell Line Encyclopedia (CCLE) projects and determined which sarcoma subtypes and subsets are associated with increased PRAME expression...

The present study evaluated the in vivo antitumor effects and toxicity of a new Ru(II) compound, cis-(Ru[phen]2[ImH]2)(2+) (also called RuphenImH [RuC]), against Walker-256 carcinosarcoma in rats. After subcutaneous inoculation of Walker-256 cells in the right pelvic limb, male Wistar rats received 5 or 10mg·kg(-1) RuC orally or intraperitoneally (i.p.) every 3 days for 13 days. A positive control group (2mg·kg(-1) cisplatin) and negative control group (vehicle) were also used. Tumor progression was checked daily...

INTRODUCTION: Carcinosarcoma is a highly malignant tumor characterized by dual malignant histologic differentiation of epithelial and mesenchymal components. The tumor is extremely rare in the sinonasal tract, with only 13 cases reported since 1957 in the literature. PRESENTATION OF CASE: We report a case of a 55-year-old man with right-sided face pain revealed a mass in the right maxillary sinus and nasal cavity. A large incisional biopsy from the nasal cavity concluded the diagnosis of carcinosarcoma...

OBJECTIVE: Uterine sarcomas (US) and carcinosarcomas (CS) are rare, aggressive cancers. The lack of reliable preclinical models hampers the search for new treatment strategies and predictive biomarkers. To this end, we established and characterized US and CS patient-derived xenograft (PDX) models. METHODS: Tumor fragments of US and CS were subcutaneously implanted into immunocompromised mice. Engrafted xenograft and original tumors were compared by means of histology, immunohistochemistry, whole-genome low-coverage sequencing for copy number variations, and RNA sequencing...

AIM: Due to the emerging experience in VATS (video assisted thoracic surgery) lobectomies, in some centers the so called "non-intubated" VATS lobectomies (NITS - non-intubated thoracic surgery) gained increased authority, during which endotracheal intubation and muscle relaxation of the patient is not carried out, thus surgery is being performed with the patient breathing spontaneously. The recent study deals with our initial experience gained during uniportal NITS VATS lobectomies. PATIENTS AND METHOD: Between 24...

Uterine carcinosarcomas (UCSs) are highly aggressive malignancies associated with poor prognoses and limited treatment options. These tumors are hypothesized to develop from the endometrial adenocarcinoma (EAC) through epithelial-mesenchymal transition (EMT). We test this long-standing hypothesis by depleting miR-200, a family of microRNAs critical for EMT, in EAC cell lines. Our data suggest that UCSs do not develop from EACs via EMT. Clinically more relevant, we show that miR-200 expression in UCS cells induces a robust mesenchymal-epithelial transition (MET)...

Carcinosarcoma of the anus is rare and has yet to be reportedly associated with the keratinocyte-specific Human Papilloma Virus (HPV). We describe a case of anal carcinosarcoma with HPV infection in both the epithelial and mesenchymal components of the tumor by immunohistochemistry, chromogenic in-situ hybridization (CISH) and further supported by electron microscopy (EM). Microscopic examination of the tumor showed nests of poorly-differentiated invasive squamous cell carcinoma with basaloid features intermixed with a hypercellular, atypical spindle cell proliferation...

Recent studies suggest that the most common and lethal type of "ovarian" cancer, high-grade serous carcinoma (HGSC), usually arises from epithelium on the fallopian tube fimbriae, and not from the ovarian surface epithelium (OSE). We have developed Ovgp1-iCreER(T2) mice in which the Ovgp1 promoter controls expression of tamoxifen (TAM)-regulated Cre recombinase in oviductal epithelium - the murine equivalent of human fallopian tube epithelium (FTE). We employed Ovgp1-iCreER(T2) mice to show that FTE-specific inactivation of several different combinations of tumour suppressor genes recurrently mutated in human HGSCs - namely Brca1, Trp53, Rb1, and Nf1 - results in serous tubal intraepithelial carcinomas (STICs) that progress to HGSC or carcinosarcoma, and to widely metastatic disease in a subset of mice...

Ovarian carcinosarcomas, rare variant of ovarian carcinoma, composed of both carcinomatous and mesenchymal components, solid and/or cystic, fleshy and hemorrhagic, frequently spreading beyond the ovary, are treated with surgery and adjuvant chemotherapy according to the treatment principles of ovarian carcinomas due to the small number of reported cases and lack of randomized studies. We report a case of a 37-year-old woman with clinical signs of extremely locally advanced tumor of ovarian origin, infiltrating the lower left quadrant of the abdominal wall with necrosis of the covering skin...

INTRODUCTION: Pelvic high-grade serous carcinomas (HGSCs) include carcinoma of ovary, fallopian tube, and peritoneum. Five-year survival, irrespective of the stage, is between 35-40%. Most patients are diagnosed in advanced stages of the disease. The new revised and expanded dualistic model of ovarian carcinogenesis shows that type II tumors are composed for the most part of high-grade serous ovarian carcinoma, carcinosarcoma, undifferentiated carcinoma and can be further subdivided into morphologic and molecular subtypes...

RATIONALE: Carcinosarcoma, an extremely rare pancreatic primary tumor, is characterized by coexistence of both carcinomatous and sarcomatous components. Due to its rarity, the clinical manifestation and imaging features have not been recognized. An accurate diagnostic method has not been available and a widely accepted guidelines instructing treatment has not been established. PATIENT CONCERNS: We present an uncommon case of pancreatic carcinosarcoma (PCS) which has been preoperatively diagnosed as pancreatic malignant intraductal papillary mucinous neoplasm...

Large-cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine tumor. LCNECs arising from the genital organs are highly malignant and rare, with <20 cases of LCNEC developing from the uterine endometrium reported to date. We herein present the case of a patient with LCNEC of the endometrium. The patient was a 52-year-old woman, who exhibited lower abdominal pain and rapid uterine enlargement during outpatient treatment for uterine myoma. The endometrial biopsy suggested a diagnosis of poorly differentiated carcinoma or carcinosarcoma...

PURPOSE: To construct a diagnostic model for differentiating carcinosarcoma from carcinoma of the uterus. MATERIALS AND METHODS: Twenty-six patients with carcinosarcomas and 26 with uterine corpus carcinomas constituted a derivation cohort. The following nine MRI features of the tumors were evaluated: inhomogeneity, predominant signal intensity, presence of hyper- and hypointense areas, conspicuity of tumor margin, cervical canal extension on T2WI, presence of hyperintense areas on T1WI, contrast defect area volume percentage, and degree of enhancement...

Endometrial carcinoma (ECA) is frequently hormonally driven and can be treated with endocrine-based therapy, yet hormone receptor status is not routinely assessed. In particular, little is known about the significance of androgen receptor (AR) in ECA. Androgen has antiproliferative effects in the healthy endometrium and could serve a similar role to progesterone in curbing the progression of estrogen-dependent neoplasia. There may also be a subset of ECA that benefits from androgen antagonistic therapy. We herein investigate AR expression across ECA subtypes and compare its expression to estrogen receptor (ER) and progesterone receptor (PR)...

OBJECTIVE: Clinical outcomes for patients with uterine carcinosarcoma are poor after surgical management alone. Adjuvant therapies including chemotherapy (CT) and/or radiation therapy (RT) have been previously investigated, but the optimal management of this disease remains controversial. The purposes of this study were to analyze the patterns of use of adjuvant CT and RT and to assess the impact on survival of each of these treatment regimens using the National Cancer Data Base. METHODS/MATERIALS: The National Cancer Data Base was queried for patients given a diagnosis of uterine carcinosarcoma confined to the pelvis who underwent total hysterectomy/bilateral salpingo-oophorectomy between 2004 and 2011...

Carcinosarcoma of the parotid gland, a true malignant mixed tumour is extremely rare. It may occur in a pre-existing pleomorphic adenoma or arise de novo. We report a case of carcinosarcoma de novo harbouring an osteosarcomatous element in a 35-year-old man along with review of the reported cases. Excision was done and histopathologic examination confirmed the diagnosis. Long term follow up has been recommended for these tumours owing to their high propensity of recurrence and metastasis. Our case discusses the importance of histopathology and limitation of preoperative imaging in the diagnosis of such an aggressive neoplasm; emphasizing the fact that possibility of carcinosarcoma should be kept in mind while dealing with salivary gland lesions even at a younger age...

Spermatic cord tumors (SCTs) are rare neoplasms with 80% exhibiting benign pathology. Of the malignant SCTs, 90% are sarcomas. To date there has only been one documented case of primary CS of the spermatic cord which occurred in a 40 year old with no reported medical history. A 76-year-old male with a history of biopsy proven Gleason score 7 (3 + 4) prostatic adenocarcinoma underwent external beam radiation therapy (7920 cGy) in 44 fractions in 2004. He presented with a 3 year history of an asymptomatic right hydrocele...
