AIM: The study was conducted to delineate the histological problems in diagnosing uterine mesenchymal tumors in morcellated material. METHODS: All cases of morcellated uteri performed between 2008 and 2014 were reviewed. The incidence of unexpected malignancy, defined as any neoplasm with a clear-cut diagnosis of leiomyosarcoma (LMS) or endometrial stromal sarcoma (ESS), was noted. Cases with absolute discrepancy between the diagnosis of the morcellated tumor and the subsequent diagnosis were also included in the study...

Endometrial stromal sarcoma (ESS) is a rare neoplasm comprising only 0.2% to 1% of all uterine malignancies and afflicts women between 42 and 59 yr of age. ESSs frequently express estrogen receptor (ER) and progesterone receptor (PR). However, the published literature contains scant data on the expression and therapeutic/prognostic role of androgen receptor (AR) in ESSs. We undertook this study to characterize the expression of AR along with ER and PR in ESSs and correlate it with clinicopathologic features...

OBJECTIVE: Uterine adenosarcoma (UAS) is a rare gynecologic malignancy and the significance of lymph node metastasis on survival has not been well studied. METHODS: A retrospective study was performed utilizing the Surveillance, Epidemiology, End Results Program to examine UAS (n=994), endometrial stromal sarcoma (ESS, n=2910), and uterine leiomyosarcoma (LMS, n=5506) diagnosed between 1973 and 2013. The impact of lymph node metastasis on cause-specific survival (CSS) was cross-compared by multivariable analysis...

Uterine carcinosarcoma (UCS) is a form of endometrial cancer simultaneously exhibiting carcinomatous and sarcomatous elements, but the underlying molecular and epigenetic basis of this disease is poorly understood. We generated complete DNA methylomes for both the carcinomatous and the sarcomatous components of three UCS samples separated by laser capture microdissection and compared DNA methylomes of UCS with those of normal endometrium as well as methylomes derived from endometrioid carcinoma, serous endometrial carcinoma, and endometrial stromal sarcoma...

BACKGROUND Paraneoplastic hypercalcemia is a well-described complication associated with a variety of malignancies. However, its incidence in gynecological malignancies is low. CASE REPORT A 53-year-old woman presented with progressive abdominal distention and irregular vaginal bleeding of several weeks' duration. A contrast CT abdomen and pelvis was significant for a mass in the lower uterine/cervical region, multiple peritoneal and omental masses, enlarged pelvic and paraaortic lymph nodes, and large-volume ascites...

Recently, there has been an intense discussion about the issue of fibroid and uterine morcellation in relation to the risk of unrecognized uterine sarcoma spread. Morcellation can negatively influence the prognosis of patients, and transecting the specimen into pieces prevents the pathologist from performing proper disease staging. Many societies have published their statements regarding this issue. The European Society for Gynecological Oncology has established a working group of clinicians involved in diagnostics and treatment of oncogynecological patients to provide a statement from the oncological point of view...

Low-grade endometrial stromal sarcoma (LGESS) is a rare malignancy. The tumor is reportedly responsive to hormonal therapy, most commonly with medroxyprogesterone acetate (MPA), but the effectiveness of aromatase inhibitors for recurrent LGESS remains unclear. The present study reports a case of stage IC LGESS presenting with abnormal uterine bleeding, and also provides a review of the literature. Following a total abdominal hysterectomy and bilateral salpingo-oophorectomy, MPA therapy was initiated; treatment was successful, but discontinued 19 months later due to disruptive side effects...

AIM: A nomogram for prediction of 12-year sarcoma-specific survival has been developed based on patients with soft tissue sarcomas treated in Memorial Sloan Kettering Cancer Centre (MSKCC). We aim to evaluate the predictive accuracy of the MSKCC sarcoma nomogram in a cohort of patients treated at an Asian institution. This has not been validated in an Asian population and thus its universal applicability remains unproven. MATERIALS AND METHODS: Between 1990 and 2013, 840 adult patients underwent treatment for primary soft tissue sarcoma (STS) at the National Cancer Centre Singapore...

The Polycomb repressive complex 2 (PRC2), which contains three core proteins EZH2, EED and SUZ12, controls chromatin compaction and transcription repression through trimethylation of lysine 27 on histone 3. The (7;17)(p15;q21) chromosomal translocation present in most cases of endometrial stromal sarcomas (ESSs) results in the in-frame fusion of the JAZF1 and SUZ12 genes. We have investigated whether and how the fusion protein JAZF1-SUZ12 functionally alters PRC2. We found that the fusion protein exists at high levels in ESS containing the t(7;17)...

Endometrial Stromal Sarcomas are rare malignant tumours of the uterus. We report the case of incidental finding of Low-Grade Endometrial Stromal Sarcoma (LGESS) that metastasized to the retroperitoneum 14 years after the original surgery in a 72-year-old woman. The patient underwent a laparotomy and excision of all tumour nodules. Considering the common recurrence of and slow growing nature of LGESS, appropriate treatment options like surgical excision and life-long follow up should be considered.

OBJECTIVE: To investigate the impact of morcellation on survival outcomes of patients affected by undiagnosed uterine sarcoma. METHODS: This is a retrospective study performed in 8 referral centers of MITO group. Data of women undergoing morcellation for apparent benign uterine myomas who were ultimately diagnosed with stage I uterine sarcoma on final pathology were compared with data of women who did not undergo morcellation. Uterine sarcoma included: leiomyosarcomas (LMS), smooth muscle tumors of uncertain malignant potential (STUMP), low-grade endometrial stromal sarcomas (LG-ESS) and undifferentiated uterine sarcomas (UUS)...

The malignant transformation of endometriosis is very uncommon. Whereas 75% of tumors arising from endometriosis arise in the ovary, location in extra-genital organs is rare and mesenchymal neoplasms are exceptional. A 47 year-old woman who underwent hysterectomy with bilateral salpingo-ooforectomy due to endometriosis 13 years before presented with abdominal pain. The magnetic resonance imaging (MRI) showed a 9.7×7.5 cm solid-cystic supravesical mass and a recto-vaginal tumor, as well as endometriotic nodules in the sigma, right parametrium and peritoneum that had significantly increased in size over a six months period...

Endometrial stromal sarcoma (ESS) is an aggressive uterine sarcoma. We report a case of a large endometrial stromal sarcoma in a 42 year nulliparous woman with chronic kidney disease presenting with acute urinary retention and irregular per vaginal bleeding. Ultrasound and Doppler imaging revealed a heterogeneous mass in the endometrial cavity with internal vascularity. Magnetic resonance imaging (MRI) revealed a large lobulated mass in the endometrial cavity extending into the vagina, causing local mass effect...

Uterine sarcoma is a very aggressive and highly lethal disease. Even after a comprehensive staging surgery or en block cytoreduction surgery followed by multimodality therapy (often chemotherapy and/or radiation therapy), many patients relapse or present with distant metastases, and finally die of diseases. The worst outcome of uterine sarcomas is partly because of their rarity, unknown etiology, and highly divergent genetic aberration. Uterine sarcomas are often classified into four distinct subtypes, including uterine leiomyosarcoma, low-grade uterine endometrial stromal sarcoma, high-grade uterine endometrial stromal sarcoma, and undifferentiated uterine sarcoma...

The 2014 World Health Organization (WHO) classification of uterine tumors revealed simplification of the classification by fusion of several entities and the introduction of novel entities. Among the multitude of alterations, the following are named: a simplified classification for precursor lesions of endometrial carcinoma now distinguishes between hyperplasia without atypia and atypical hyperplasia, the latter also known as endometrioid intraepithelial neoplasia (EIN). For endometrial carcinoma a differentiation is made between type 1 (endometrioid carcinoma with variants and mucinous carcinoma) and type 2 (serous and clear cell carcinoma)...

PURPOSE: To assess the clinical outcomes and fertility of young women with stage I low-grade endometrial stromal sarcoma (ESS) treated with fertility-sparing surgery. RESULTS: Seventeen patients with stage I low-grade ESS (stage IA, n = 6; stage IB, n = 11) were entered into this study. Adjuvant hormone therapy was administered to 15 (88.2%) patients. At a median follow-up of 39 months (range, 4-106 months), 10 (58.8%) patients developed recurrence. All 10 patients had stage IB disease; among them, the first recurrence limited to the uterus was observed in 6 patients...

OBJECTIVE: Uterine sarcomas are rare, highly aggressive tumors with an unfavorable prognosis. The role of lymphadenectomy (LAD) remains controversial for this particular tumor type. To examine whether LAD can assist in prognosis or clinical benefits for uterine sarcoma patients, we performed a meta-analysis based on published studies. METHODS: We initially identified published studies by searching the PubMed database up to 30 November 2015. Study quality was evaluated systematically using the Newcastle-Ottawa Scale for assessing the quality of studies for inclusion in meta-analyses...
