OBJECTIVES: The objectives of this study were to compare preoperative and postoperative tumor grade to determine if surgical staging decisions for endometrial cancer based on preoperative biopsy are feasible and whether obesity affects the agreement. METHODS: A retrospective cohort study of women with endometrial cancer between January 2010 and December 2011 was performed. Demographics, stage of final pathology, biopsy method, preoperative and postoperative tissue grade, and histology were abstracted and stratified by patient body mass index (obese ≥30 kg/m and nonobese <30 kg/m)...

We addressed uncertainties regarding Hereditary Leiomyomatosis and Renal Cell Carcinoma (HLRCC) by exploring all French cases, representing the largest series to date. Fumarate Hydratase (FH) germline testing was performed with Sanger sequencing and qPCR/MLPA. Enzyme activity was measured when necessary. We carried out whenever possible a pathology review of RCC and S-(2-succino)-cysteine (2SC)/fumarate hydratase immunohistochemistry. We estimated survival using non-parametric Kaplan-Meier. There were 182 cases from 114 families...

Uterine sarcomas are rare malignant uterine neoplasms that are responsible for a large majority of uterine cancer-associated deaths. The subtypes include leiomyosarcomas, endometrial stromal tumors, and adenosarcomas. Standard treatment includes complete surgical resection. Adjuvant treatment with chemotherapy, hormonal therapy, or radiation may be considered in patients with high-risk disease. However, because the ability of adjuvant treatment to improve overall survival in patients with uterine sarcomas is unclear, there is no standard recommendation regarding adjuvant therapy...

We performed genomic, epigenomic, transcriptomic, and proteomic characterizations of uterine carcinosarcomas (UCSs). Cohort samples had extensive copy-number alterations and highly recurrent somatic mutations. Frequent mutations were found in TP53, PTEN, PIK3CA, PPP2R1A, FBXW7, and KRAS, similar to endometrioid and serous uterine carcinomas. Transcriptome sequencing identified a strong epithelial-to-mesenchymal transition (EMT) gene signature in a subset of cases that was attributable to epigenetic alterations at microRNA promoters...

BACKGROUND: Uterine sarcoma is a rare tumor that is often difficult to classify based on morphological and immunohistochemical analysis alone. Limited access to molecular biological analysis in routine practice would hinder making a definitive diagnosis. CASE PRESENTATION: In this report, we describe a case of a mesenchymal tumor arising from the uterine cervix in a 52-year-old woman. From microscopic morphology of the resected specimen, epithelioid leiomyosarcoma, high-grade endometrial stromal sarcoma, or uterine gastrointestinal stromal tumor (GIST) were considered as differential diagnoses...

BACKGROUND: Leiomyosarcomas (LMS) and endometrial stromal sarcomas (ESS) may display overlapping histomorphology, which may challenge diagnostic accuracy. Since LMS and ESS have vastly different clinical behavior and adjuvant therapy recommendations, accurate diagnosis is critical. CASE: We present the case of an 83-year-old female with postmenopausal bleeding who underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy for clinically atypical appearing leiomyomata...

Uterine myometrial tumors are predominantly benign conditions that affect one-third of women and represent the main indication for hysterectomy. Preoperative imaging is of utmost importance for characterization and for precise mapping of myometrial tumors to best guide therapeutic strategy. New minimally invasive therapeutic strategies including morcellation, myolysis, uterine artery embolization and image-guided radiofrequency or focused ultrasound ablation have been developed for the treatment of uterine leiomyoma...

Overexpression of the efflux pump P-glycoprotein (P-gp) is one of the important mechanisms of multidrug resistance (MDR) in many tumor cells. In this study, 26 novel 5-oxo-hexahydroquinoline derivatives containing different nitrophenyl moieties at C4 and various carboxamide substituents at C3 were designed, synthesized and evaluated for their ability to inhibit P-gp by measuring the amount of rhodamine 123 (Rh123) accumulation in uterine sarcoma cells that overexpress P-gp (MES-SA/Dx5) using flow cytometry...

The diagnosis of an unsuspected leiomyosarcoma after hysterectomy for the treatment of a presumed benign leiomyoma is a rare but highly clinically significant event. In order to facilitate removal of large uterine specimens using a minimally invasive surgical approach, morcellation with extraction in pieces is often performed. In the event of unsuspected malignancy, this may result in abdominal dispersion of the tumor and contribute to poorer survival. Modern surgical innovations always work toward improving minimally invasive strategies...

Leiomyosarcoma, a rare tumor subtype, accounts for 1% of all uterine malignancies, but contributes to a significant proportion of uterine cancer deaths. Surgery is considered the mainstay of treatment for all soft tissue sarcomas, including uterine variants. However, uterine leiomyosarcoma is challenging to diagnose preoperatively and can mimic the appearance of benign uterine leiomyomas. Recently, concerns have grown in this regard, as surgeons have utilized uterine morcellation and myomectomy procedures unknowingly in the setting of occult uterine sarcoma...

We investigated whether 16α-[18F]-fluoro-17β-estradiol (18F-FES) and 18F-fluoro-deoxyglucose (FDG) uptake measured using positron emission tomography (PET) predicted prognosis in 18 patients with different histological subtypes of uterine sarcoma. Standardized uptake values (SUVs) and 18F-FDG/18F-FES SUV ratios were determined, and their correlations with progression-free (PFS) and overall survival (OS) were examined. Ten patients died from local recurrence or metastasis, and one more experienced recurrence, during the at least 36-month follow-up period...

Leiomyosarcomas represent the most common variant of uterine sarcomas, and are also considered to be the least chemosensitive. To date, adriamycin and ifosfamide are believed to be the most effective drugs for its treatment, in addition to docetaxel and gemcitabine. Recently, the introduction of trabectedin has provided clinicians with another treatment option, and the drug may have some benefits for patients as it may allow for long-term treatment. We present the case of a patient who previously failed multiple cycles of chemotherapy and who was subsequently treated with 30 cycles of trabectedin as third-line therapy for multiple metastases of uterine leiomyosarcoma...

Mullerian adenosarcoma (MA) is a rare tumor variant with low malignancy potential and is reported to account for 8% of all uterine sarcomas. Cervical MAs are reported to occur in relatively younger patients with the mean age of 27 years, while those in the uterine corpus generally present in postmenopausal women. Due to the rarity of cervical MAs, optimal management for these patients (especially younger women) is still under exploration. Here, we describe a case of cervical MA in a woman of reproductive age who was treated by fertility-preserving surgery and successfully delivered a child 18 months later...
