Carcinosarcomas are rare biphasic neoplasms with distinct malignant epithelial and mesenchymal components. Most commonly, carcinosarcomas arise in the uterus as malignant mixed müllerian tumors, but also infrequently appear in other organs such as the ovaries and breast, the prostate and urinary tract, the lungs, or in the gastrointestinal system, among others. Pancreatic carcinosarcomas are exceedingly rare; only a few cases are reported in the English literature. Their pathogenesis remains to be fully clarified...

BACKGROUND: Minorities have demonstrated an increased risk for type II endometrial cancers, but no data exists about risk among minority subpopulations. Our objective was to evaluate heterogeneity in risk of type II endometrial cancer (EC) histologies across race and Hispanic sub-groups using data from Florida's statewide cancer registry (FCDS). METHODS: FCDS contains data on N=26,416 women diagnosed with EC from 2004 to 2013. Our analysis included women ≥18years of age who were classified as non-Hispanic White (NHW), non-Hispanic Black (NHB) or belonged to one of five Hispanic sub-groups, and had a histology code consistent with type I or type II EC...

BACKGROUND: Uterine carcinosarcoma (UCS) is a relatively rare and very aggressive tumor. The predictors of survival for patients with UCS have not been determined clearly yet. The aim of the present study was to investigate the possible predictors of disease-free survival (DFS) and overall survival (OS) for patients with UCS. METHODS AND MATERIALS: All patients with UCS who were treated surgically at a university-based Gynecology Oncology Clinic between January 2008 and December 2014 were recruited into this retrospective cohort study...

BACKGROUND: Cancer cachexia is a multifactorial metabolic syndrome characterized by marked loss of adipose tissue and skeletal muscle. Fat loss from adipose tissue in cancer cachexia is partly the result of increased lipolysis. Despite the growing amount of studies focused on elucidating the mechanisms through which lipolysis-related proteins regulate the lipolytic process, there are scarce data concerning that profile in the adipose tissue of cancer cachectic patients. Considering its fundamental importance, it was our main purpose to characterize the expression of the lipolysis-related proteins in the white adipose tissue of cachectic cancer patients...

Primary osteosarcoma of the uterine cervix is extremely rare. Only 20 cases have been reported, 19 of which originated in the uterine corpus. We report a case of primary uterine cervical osteosarcoma with pulmonary metastasis in a 30-year-old nulligravida woman. The initial diagnosis was carcinosarcoma of the uterine cervix, as detected by cervical cytology and biopsy analysis. We performed a total hysterectomy, bilateral salpingo-oophorectomy and colostomy without macroscopic residual tumors in the abdominal cavity, but pelvic recurrent tumors appeared 14 days postoperatively...

The epithelial-to-mesenchymal transition (EMT) is a reversible process comprised of various subprograms via which epithelial cells reduce their intercellular adhesions and proliferative capacity while gaining a mesenchymal phenotype with increased migratory and invasive properties. This process has been well described in several carcinomas, which are cancers of epithelial origin, and is crucial to metastatic tumor cell dissemination and drug resistance. In contrast, the precise role of EMT-related processes in tumors originating from mesenchymal tissues, such as bone and soft-tissues sarcomas, is still largely unclear...

INTRODUCTION: Although black patients with endometrial cancer (EC) have worse survival compared with white patients, the interaction between age/race has not been examined. The primary objective was to evaluate the impact of age at diagnosis on racial disparities in disease presentation and outcome in EC. METHODS: We evaluated women diagnosed with EC between 1991 and 2010 from the Surveillance, Epidemiology, and End Results. Mutation status for TP53 or PTEN, or with the aggressive integrative, transcript-based, or somatic copy number alteration-based molecular subtype were acquired from the Cancer Genome Atlas...

Lung carcinosarcoma (PCS) and other histological subtypes of non-small cell lung cancer, such as primary pulmonary lymphoma (PPL), pulmonary carcinoid (PC), and primary pulmonary lymphoepithelioma-like carcinoma (LELC), are rare. For their low incidence, the diagnosis and treatment are still controversial. Some patients only need surgery, while others may need chemotherapy, radiotherapy, or targeted therapy. In this paper, we retrospectively reviewed the literature of some rare histological subtype of NSCLC for the recent 20 years, and try to get some conclusions...

We present a case of an elderly female patient who presented with a 6-month history of progressive slurred speech, vertigo, unsteadiness and falls. She underwent an extensive battery of neurological and cardiovascular investigations, none of which demonstrated a diagnostic cause for her symptoms. She was referred to the stroke and neurology teams and was started on treatment for presumed anxiety. As her symptoms continued to progress, she was referred to the falls service. Following a multidisciplinary team discussion, she was reviewed by the consultant geriatrician who felt this may be due to a malignancy so the consultant geriatrician arranged blood testsand CT scan of her chest, abdomen and pelvis...

We present a case of a 61-year-old postmenopausal woman with a known diagnosis of malignant mixed müllerian tumor (MMMT) originally treated with systemic chemotherapy and total abdominal hysterectomy plus bilateral salpingo-oophorectomy, who developed a left cervical mass noted on a follow-up visit. Imaging and nuclear testing were both performed confirming the presence of a cervical mass arising from the thyroid. Our patient underwent surgical resection of the mass, and biopsy of the specimen was consistent with metastatic uterine carcinosarcoma mixed müllerian tumor...

Immunotherapy has recently become a new focus for the treatment of malignant tumors following the surgery, chemotherapy, radiotherapy, and molecular targeted therapy. Nivolumab, a human monoclonal antibody, is the first programmed cell death protein-1 (PD-1) inhibitor, which can prohibit the interaction of its ligand (PD-L1), restoring the immune response of T cells, and enhancing the recognition of tumor cells by the immune system.Pulmonary Carcinosarcoma is an uncommon but highly aggressive tumor type with a poor prognosis...

OBJECTIVE: The mechanisms underlying the histogenesis and aggressiveness of uterine carcinosarcoma (UCS) are poorly understood; however, previous studies implicate epithelial-mesenchymal transition (EMT). Fascin is a proinvasive, actin-bundling protein and an important component of EMT. It is associated with poor outcomes in human carcinoma, especially in estrogen receptor (ER)-negative tumors arising in organs normally expressing ER. We sought to evaluate fascin expression in UCS and its relationship to ER status, clinicopathologic indicators of tumor aggressiveness, and survival outcomes...

Distinguishing between uterine neoplasms of smooth muscle and endometrial stromal origin is a frequent diagnostic challenge. We investigated the staining pattern of interferon-induced transmembrane protein-1 (IFITM1), a novel endometrial stromal marker, in endometrial and smooth muscle uterine neoplasms and compared it with CD10 in its ability to differentiate between these two groups. Immunohistochemistry for IFITM1 and CD10 was performed in 20 cases of smooth muscle neoplasms (10 cases leiomyoma, 10 cases leiomyosarcoma), 14 cases of endometrial stromal sarcoma (ESS) (12 cases of low grade and 2 cases of high grade) and 12 cases of carcinosarcoma...

Sentinel lymph node (SLN) sampling may provide staging information without exposing patients to risks of lymph node dissection. There is no consensus protocol for optimal pathologic handling of these specimens. This study compares 2 ultrastaging protocols of SLN in endometrial carcinoma (EC). All SLN were serially sectioned perpendicular to the long axis in 2 mm intervals and entirely submitted for routine hematoxylin and eosin (H&E) processing. SLN negative by routine processing had ultrastaging (US) by one of the following: method 1 (M1), 5 H&E levels at 250 μm intervals with 2 unstained slides at each level; pankeratin immunohistochemistry (IHC) performed on level 1 in cases with negative H&E levels or method 2 (M2), 1 H&E level + 2 unstained slides cut 250 μm into the tissue block; pankeratin IHC performed in cases with negative H&E...
