INTRODUCTION: Primary malignant mixed mesodermal tumor (MMMt, also called malignant mixed Mullerian tumor and designated in the WHO classification of female genital tract neoplasms as carcinosarcoma) is an infrequent tumor that develops usually in the uterus and more rarely in the ovary. Extragenital tumor, including primary peritoneal MMMt, is an extremely rare and aggressive neoplasm with only few case reported in the literature. PRESENTATION OF CASE: We report a case of a 70-year's old female who presented with nausea and abdominal discomfort for 6 months...

BACKGROUND: The Food and Drug Administration recently announced that the use of morcellation may cause fibroids or pelvic dissemination and metastasis of uterine sarcoma; therefore, the use of morcellation is limited in the USA. A large sample study is necessary to assess the proportion of uterine malignant tumors found in patients with laparoscopic myomectomy. METHODS: A national multicenter study was performed in China. From 2002 to 2014, 33,723 cases were retrospectively selected...

Transcriptional repression of ubiquitin B (UBB) is a cancer-subtype-specific alteration that occurs in a substantial population of patients with cancers of the female reproductive tract. UBB is 1 of 2 genes encoding for ubiquitin as a polyprotein consisting of multiple copies of ubiquitin monomers. Silencing of UBB reduces cellular UBB levels and results in an exquisite dependence on ubiquitin C (UBC), the second polyubiquitin gene. UBB is repressed in approximately 30% of high-grade serous ovarian cancer (HGSOC) patients and is a recurrent lesion in uterine carcinosarcoma and endometrial carcinoma...

Epigenetic regulatory mechanisms are a current focus in studies investigating cancer. Chromatin remodeling alters chromatin structure and regulates gene expression, and aberrant chromatin remodeling is involved in carcinogenesis. AT-rich interactive domain-containing protein 1A (ARID1A) and SWItch/sucrose non-fermentable-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a, member 4 are remodeling factors that are mutated in numerous types of cancer. In gynecological cancer, ARID1A mutations have been identified in 46-57% of clear cell carcinoma and 30% of endometrioid carcinoma...

PURPOSE: In the postoperative management of uterine carcinosarcoma (UCS), the roles of individual radiotherapy (RT) modalities, chiefly external-beam radiotherapy (EBRT) and brachytherapy (BT), remain undefined. We analyzed the survival impact of EBRT and BT using the National Cancer Database. METHODS AND MATERIALS: We abstracted women diagnosed with UCS from 2004 to 2012 who received hysterectomy and had complete RT information. Cox multivariate analysis and propensity-score matched analyses were used to compare survival among radiotherapeutic approaches...

A 76-year-old female with coronary artery disease, chronic obstructive pulmonary disease, diabetes mellitus type II, and 40 pack-year smoking history presented with a four-day history of cough, productive of green-yellow sputum. Chest X-ray revealed opacification of the left upper lung field, and computed tomography (CT) of the chest showed a large cavitary lesion invading the T2-T3 vertebral bodies, extending into the epidural space, giving rise to mild cord compression. Biopsy of the lesion revealed a poorly differentiated neoplasm composed of distinct epithelial and mesenchymal components, consistent with carcinosarcoma...

INTRODUCTION: Carcinosarcoma of the bladder is a very rare neoplasm. The pathogenesis of carcinosarcomas is not clearly understood and remains a subject of debate. Whilst there is some research conceptualizing the histopathological findings of bladder carcinosarcomas, the demographic features, clinical outcomes, prognosis and treatment options remain unclear. MATERIALS AND METHODS: We analyzed 12 consecutive cases of patients with sarcoma-toid bladder cancer who were treated surgically at a single Urology Department be-tween 1999 and 2015...

Non-Hispanic black (NHB) women are more likely to experience an endometrial carcinoma (EC) recurrence compared with Non-Hispanic white (NHW) women. The extent to which tumor characteristics, socioeconomic status (SES), and treatment contribute to this observation is not well defined. In the NRG Oncology/Gynecology Oncology Group (GOG) 210 Study we evaluated associations between race and ethnicity with EC recurrence according to tumor characteristics with adjustment for potential confounders. Our analysis included 3,199 non-Hispanic white, 532 non-Hispanic black and 232 Hispanic women with EC...

Odontogenic tumours are lesions that occur solely within the oral cavity and are so named because of their origin from the odontogenic (i.e. tooth-forming) apparatus. Odontogenic tumours comprise a variety of lesions ranging from non-neoplastic tissue proliferations to benign or malignant neoplasms. However, controversies exist regarding the pathogenesis, categorisation and clinical and histological variations of these tumours. The recent 2017 World Health Organization classification of odontogenic tumours included new entities such as primordial odontogenic tumours, sclerosing odontogenic carcinomas and odontogenic carcinosarcomas, while eliminating several previously included entities like keratocystic odontogenic tumours and calcifying cystic odonogenic tumours...

This paper reviews CNS involvement secondary to malignant-mixed Müllerian tumor or uterine carcinosarcoma, a rare aggressive biphasic Müllerian tumor. We report a cerebellar metastasis with epithelial and mesenchymal components, demonstrating heterologous rhabdomyogenic and chondroblastic differentiation. The patient had undergone total abdominal hysterectomy and bilateral salpingo-oophorectomy for palliation of symptomatic chemotherapy-resistant node-positive disease. CNS involvement is rare, and prognostically poor, and suggestively poorer in predominantly sarcomatous metastases...

Pin2/TRF1-interacting telomere inhibitor 1 (PinX1) was originally identified as a telomerase inhibitor, involved in maintaining telomerase activity, telomere length, and chromosomal stability. However, research has shown that PinX1 can have opposing molecular status in its expression patterns in several other tumor types. We thus investigated the genetic profile and biological implication of PinX1 in several human cancers using the cBioportal database. Our results showed that PinX1 deletion accounted for the most alterations, with the frequency of its deletion regularly occurring in pathological types of carcinosarcoma and adenocarcinoma...

OBJECTIVE: Endometrial cancer can be diagnosed early and cured, yet cases that recur portend a very poor prognosis with over 10,000 women succumbing to the disease every year. In this study we addressed the question of how to recognize cases likely to recur early in the course of therapy using dysregulation of tumor microRNAs (miRNAs) as predictors. METHODS: Using the tissue collection from Gynecologic Oncology Group Study-210, we selected and analyzed expression of miRNAs in 54 recurrent and non-recurrent cases...

Carcinosarcoma of the urinary bladder is a rare neoplasm that is histologically composed of malignant epithelial and mesenchymal components. The etiology of sarcomatoid tumors is unclear, but smoking and history of previous radiotherapy or chemotherapy may lead to bladder disorders and to the formation of sarcomatoid carcinoma. These neoplasms behave as highly aggressive tumors and optimal treatment is uncertain. Herein, we report a case of sarcomatoid carcinoma of urinary bladder presenting as a giant intravesical mass in a 61-year-old man complaining of macroscopic hematuria...

We report a case of port-site metastasis after laparoscopic surgery for early stage uterine carcinosarcoma (UCS) and review the related literature. A 53-year-old woman with suspected uterine malignance underwent a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy, infra-colic omentectomy, and pelvic lymphadenectomy resulting pathologically in a stage IA UCS. Twelve months later she developed a palpable abdominal-wall mass at the trocar site without other synchronous metastases. A mass resection was performed and it was pathologically diagnosed with port-site metastasis of UCS...
