We report a retrospective study of 47 consecutive patients with uterine sarcoma treated at the Churchill Hospital in Oxford between 1990-1998. The mainstay of treatment was surgery with adjuvant chemotherapy and radiotherapy reserved for selected patients with early stage disease. Overall 1 and 2 year survival was 49% and 30% respectively compared with 73% and 55% in the group who received adjuvant chemotherapy/radiotherapy. Median survival was 11 months for the group as a whole compared to 32.9 months in the adjuvant therapy group. This is a retrospective review with small numbers and considerable selection bias, however, given the poor survival of patients with this disease, adjuvant treatment should be considered in future trials of patients with uterine sarcoma.

To investigate the impact of morcellation on survival outcomes of patients affected by undiagnosed uterine sarcoma. 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). Two-year survival outcomes were evaluated using Kaplan-Meir and Cox models. Overall 125 patients were identified: 31(24.8%), 21(16.8%) and 73(58.4%) patients had power morcellation during laparoscopy, non power morcellation during open surgery and non morcellation during open procedures, respectively. Considering patients affected by LMS, morcellation did not correlated with disease-free survival. However, patients undergoing either morcellation or power morcellation experienced a 3-fold increase risk of death in comparison to patients who had not morcellation (p=0.02). A trend towards an increase of recurrence was observed for patients undergoing morcellation for STUMP (HR 7.7, p=0.09); while no differences in survival outcomes were observed for patients with LG-ESS and UUS. Our data suggest that morcellation increase the risk of death in patients affected by undiagnosed LMS. Further prospective studies are warranted in order to assess the risk to benefit ratio of power morcellator utilization in patients with apparent benign uterine myomas. Copyright © 2016 Elsevier Inc.

To analyze the efficacy of positron emission tomography/computed tomography (PET/CT) for the diagnosis of uterine sarcoma. Thirty-four patients evaluated between January 2010 and March 2015 were retrospectively enrolled. All patients in whom uterine sarcoma was suspected based on contrast-enhanced magnetic resonance imaging (MRI) findings (heterogeneous, high signal intensity on T2-weighted images and/or high intensity on T1-weighted images) underwent PET/CT for further assessment. Patients were divided into 2 groups based on postoperative pathological findings: uterine sarcoma (n = 15) and leiomyoma (n = 19). The maximum standardized uptake value (SUVmax) of all lesions was measured using PET/CT; we calculated the optimal cutoff value for diagnosing sarcoma. The median SUVmax for uterine sarcoma and leiomyoma was 12 and 4.1, respectively; these values were significantly different. An SUVmax of greater than 7.5 was able to exclude leiomyoma with 80.8% sensitivity and 100% specificity (area under the curve, 95.3%). A cutoff SUVmax of 7.5 yields 100% specificity, and a cutoff SUVmax of 4.4 yields a 100% negative predictive value (NPV). The combination of PET/CT and lactate dehydrogenase (LDH) levels had a sensitivity of 86.6%, specificity of 100%, positive predictive value of 100%, and an NPV of 90.4%. No relation between histopathology or International Federation of Gynecology and Obstetrics (FIGO) stage and 18-fluoro-2-deoxy-d-glucose uptake value on PET/CT was seen. The surgical outcome trended toward a correlation with the SUVmax, although this was not statistically significant. In patients with MRI findings consistent with either uterine sarcoma or leiomyoma, PET/CT can decrease the false-positive rate by setting an optimal cutoff SUVmax of 7.5. Using this cutoff can avoid unnecessary surgery. Copyright © 2017. Published by Elsevier B.V.

Uterine sarcomas are rare and the clinical diagnosis of sarcoma is difficult. Diagnostic and surgical hysteroscopy is a minimally invasive outpatient procedure that makes an accurate diagnosis of malignant intrauterine pathology and could play a role in the diagnosis of the uterine sarcomas. Uterine sarcomas diagnosed at the Department of Gynecology of Sant Joan University Hospital by hysteroscopy between January 2004 and August 2010 are described. In this period 2,441 hysteroscopies were performed; a total of 67 adenocarcinomas of the endometrium and five sarcomas were diagnosed by hysteroscopy. The data are presented with a review of the literature, focusing on the diagnostic value of hysteroscopy in these tumors.

The objective of this study was to find clinical parameters and qualitative and quantitative magnetic resonance imaging (MRI) features for differentiating uterine sarcoma from atypical leiomyoma (ALM) preoperatively and to calculate predictive values for uterine sarcoma. Data from 60 patients with uterine sarcoma and 88 patients with ALM confirmed by surgery and pathology were collected. Clinical parameters, qualitative MRI features, diffusion-weighted imaging with apparent diffusion coefficient values, and quantitative parameters of dynamic contrast-enhanced MRI of these two tumor types were compared. Predictive values for uterine sarcoma were calculated using multivariable logistic regression. Patient clinical manifestations, tumor locations, margins, T2-weighted imaging signals, mean apparent diffusion coefficient values, minimum apparent diffusion coefficient values, and time-signal intensity curves of solid tumor components were obvious significant parameters for distinguishing between uterine sarcoma and ALM (all P <.001). Abnormal vaginal bleeding, tumors located mainly in the uterine cavity, ill-defined tumor margins, and mean apparent diffusion coefficient values of <1.272 × 10 -3  mm 2 /s were significant preoperative predictors of uterine sarcoma. When the overall scores of these four predictors were greater than or equal to 7 points, the sensitivity, the specificity, the accuracy, and the positive and negative predictive values were 88.9%, 99.9%, 95.7%, 97.0%, and 95.1%, respectively. The use of clinical parameters and multiparametric MRI as predictive factors was beneficial for diagnosing uterine sarcoma preoperatively. These findings could be helpful for guiding treatment decisions. Copyright © 2018 The Association of University Radiologists. Published by Elsevier Inc. All rights reserved.

To gain more information about the knowledge of the clinical management of uterine sarcoma. This survey was performed among members of the North-Eastern German Society of Gynecological Oncology (NOGGO) and the German Society of Psychosomatic Medicine in Gynecology and Obstetrics (DGPFG) on the treatment of uterine sarcomas. Altogether, 374 gynecologists took part. When asked about the surgical therapy of leiomyosarcoma, 64% indicated hysterectomy with bilateral adenectomy and lymph node dissection. Answers on the extent of lymphadenectomy in leiomyosarcoma differed widely. When asked about the preferred chemotherapy regimen for metastatic uterine sarcoma, more than 60% of all gynecologists would not apply any chemotherapy. Almost 40% recommended any kind of radiotherapy in this situation. There is a great uncertainty about the standard treatment of uterine sarcoma, even among specialists of gynecological oncology. It is time for organized efforts to improve the treatment of uterine sarcoma.

A 53-year-old woman who had undergone hystero-oophorectomy for uterine endometrial stromal sarcoma in our hospital 9 months previously was referred to our hospital because of bilateral pneumothorax. Chest computed tomography scan on admission revealed multiple thin-walled cavity nodules in both lung and a bilateral pneumothorax, suggesting pulmonary metastases of the uterine endometrial stromal sarcoma. We surgically treated the pneumothorax and diagnosed the nodules as metastatic lesions. They were pathologically diagnosed as metastatic uterine endometrial stromal sarcoma.

Uterine sarcomas are rare and aggressive gynaecologic malignancies with poor prognosis, arising from myometrial or endometrial tissue. These rare cancers can be aggressive, and account for a greatly disproportionate amount of deaths from uterine cancers. The histological uterine sarcomas classification includes carcinosarcomas (malignant mesodermal mixed tumors), accounting for 40% of cases, leiomyosarcomas (40%) and endometrial stromal sarcomas (10-15%). Each group of these tumors presents differences in diagnosis, prognostic factors, treatment, and outcome. Uterine leiomyosarcomas typically affects women in their sixth decade of life, presenting with atypical symptoms such as abnormal uterine bleeding and abdominal pain. The optimal treatment of uterine leiomyosarcomas is surgery, including total abdominal hysterectomy and bilateral salpingooophorectomy. The aim of this study was to conduct a systematic review of the literature regarding the standard surgical procedure of uterine leiomyosarcomas and investigate whether lymphadenectomy affects the 5-year DSS, as well as other relevant clinical outcomes, in women with uterine leiomyosarcomas. For this purpose, MEDLINE, EMBASE, and the Cochrane Library databases were reviewed, and a critical account of the management strategies of these tumors is presented.

Endometrial stromal sarcoma is a rare uterine cancer with no reliable method for preoperative diagnosis. A 30-year-old parous woman underwent laparoscopic supracervical hysterectomy because of a leiomyoma. The uterus was removed from the abdominal cavity with an electric morcellator with a spinning blade. The pathology report revealed low-grade endometrial stromal sarcoma. Two months after the initial surgery, a second laparoscopic procedure was performed. The final pathology report confirmed low-grade endometrial stromal sarcoma involving the ovary, fallopian tube, and ovarian artery. It was concluded that morcellation of leiomyomas at laparoscopic supracervical hysterectomy may potentially increase metastasis if the tumor is a sarcoma. Copyright © 2010 AAGL.

Uterine fibroids often require a hysterectomy or myomectomy via laparotomy or laparoscopy. Morcellation is often necessary to perform a laparoscopic surgery. The objective of this study is to determine the incidence of unexpected uterine sarcomas (UUSs) after hysterectomy and myomectomy for uterine fibroids and to reduce the occurrence and avoid the morcellation of UUSs by analyzing their characteristics. Women who had a hysterectomy or myomectomy for uterine fibroids in Shengjing Hospital of China Medical University between November 2008 and November 2014 were selected for the study, and their clinical characteristics were analyzed. During the period, 48 UUSs were found in 10,248 cases, and the overall incidence was 0.47%. There was no statistical difference (P=0.449) regarding the incidence (0.50% vs 0.33%) between 42 UUSs in 8,456 cases undergoing laparotomy and six UUSs in 1,792 cases undergoing laparoscopy. Most of the UUSs were stage I (89.58%), which occurred more commonly (56.25%) in women aged 40-49. Abnormal uterine bleeding (39.58%) was the main clinical manifestation. Rapidly growing pelvic masses (12.5%), rich blood flow signals (18.75%), and degeneration of uterine fibroids (18.75%) prompted by ultrasonography may suggest the possibility of UUSs. The margins of most UUSs (93.75%) were regular, which may cause UUSs to be misdiagnosed as uterine fibroids. Fifteen cases underwent magnetic resonance imaging examinations. Approximately 73.33% showed heterogeneous and hypointense signal intensity on T1-weighted images, and 80% showed intermediate-to-high signal intensity on T2-weighted images, with necrosis and hemorrhage in 40% of cases. After contrast administration, 80% presented early heterogeneous enhancement. The incidence of UUSs after hysterectomy and myomectomy for uterine fibroids was low, and their clinical characteristics are atypical. It is necessary and very critical to make a complete and cautious preoperative evaluation to reduce the occurrence and avoid the morcellation of UUSs.

Endometrial stromal tumors: the new WHO classification.

Conklin, Christopher M J; Longacre, Teri A

2014-11-01

Endometrial stromal tumors are rare uterine mesenchymal neoplasms that have intrigued pathologists for years, not only because they commonly pose diagnostic dilemmas, but also because the classification and pathogenesis of these tumors has been widely debated. The current World Health Organization recognizes 4 categories of endometrial stromal tumor: endometrial stromal nodule (ESN), low-grade endometrial stromal sarcoma (LG-ESS), high-grade endometrial stromal sarcoma (HG-ESS), and undifferentiated uterine sarcoma (UUS). uterine sarcoma. These categories are defined by the presence of distinct translocations as well as tumor morphology and prognosis. Specifically, the JAZF1-SUZ12 (formerly JAZF1-JJAZ1) fusion identifies a large proportion of ESN and LG-ESSs, whereas the YWHAE-FAM22 translocation identifies HG-ESSs. The latter tumors appear to have a prognosis intermediate between LG-ESS and UUS, which exhibits no specific translocation pattern. This review (1) presents the clinicopathologic features of endometrial stromal tumors; (2) discusses their immunophenotype; and (3) highlights the recent advances in molecular genetics which explain their pathogenesis and lend support for a new classification system.

Ewing sarcoma-primitive neuroectodermal tumors (ES/PNETs) constitute a family of neoplasms characterized by a continuum of neuroectodermal differentiations. ES/PNET of the uterus is rare. There are 48 cases of ES/PNET of the uterus published in the literature as far as we know. We describe a case of Ewing sarcoma of the uterus occurring in a 17-year-old woman presenting with a two-month history of pelvic pain. After surgical excision and microscopic, immunohistochemical, and electron microscopy examination, the diagnosis of Ewing sarcoma of the uterus was suggested. This report will discuss the diagnosis and surgical and clinical management of Ewing uterine sarcoma in young women, according to the available literature. In spite of the rarity of ES/PNETs, they should be taken into account in the differential diagnosis of uterine neoplasms in young women.

Ewing's sarcoma is usually diagnosed in adolescents and young adults, peak of incidence is around 15 years of age. Primary localization is mostly in the skeleton of long bones and chest wall. Primary extraosseous involvement rarely occurs, incidence increases with age. We present a case report of a 57-year-old patient with locally advanced tumors of the cervix, clinical stage IIB. Due to histological and molecular genetic examination revealing EWS -ERG fusion gene, Ewing's sarcoma was diagnosed. CT revealed pathological pelvic lymphadenopathy and multiple pulmonary bilateral methastases, scintigraphy did not prove any affection of skeleton. The patient underwent a two-stage intensive chemotherapy regimens VIDE (vincristine, ifosfamide, doxorubicin, etoposide) and VAI (vincristine, actinomycin D, ifosfamide). During the second phase, concomitant radiotherapy of pelvis was aplied. According to PET/CT, complete remission was achieved. Whole-lung irradiation was applied in consolidation of the result. Primary Ewing's sarcoma of the cervix is an extremely rare disease. To our knowledge, only 12 cases was presented until this time. The average age at time of dia-gnosis was 35 years. Unlike the previous reports, we initially diagnosed distant metastases. The treatment was led according to the protocol Ewing 2008 designed for primary skeletal Ewing's sarcoma. Currently, 18 months after the therapy, the patient is without signs of disease. However, long-term follow-up is necessary.

Cervical Mullerian adenosarcoma with heterologous sarcomatous overgrowth: a fourth case and review of literature.

Uterine sarcomas are relatively rare tumors that account for approximately 1-3% of female genital tract malignancies and between 4-9% of uterine cancers. Less than 8% of all cases are Mullerian adenosarcoma, a distinctive uterine neoplasm characterized by a benign, but occasionally atypical, epithelial and a malignant, usually low-grade, stromal component, both of which should be integral and neoplastic constituents of the tumor. Mullerian adenosarcoma with sarcomatous overgrowth (MASO) is a very aggressive variant, associated with post-operative recurrence, metastases, even when diagnosed in early stage. We present a fourth MASO case derived from uterine cervix in a 72-year-old woman with metrorrhagia and a polypoid mass protruding through the cervical ostium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic lymph node dissection, omental biopsy and appendectomy were performed. Surgery treatment was associated with adjuvant whole-pelvis radiation (45 Gy) and adjuvant chemotherapy (cisplatin/ifosfamide). After nine months of follow up, the patient was free of tumor. The rarity of MASO of the cervix involves a management difficult. Most authors recommend total abdominal hysterectomy, usually accompanied by bilateral salpingo-oophorectomy. There is no common agreement on staging by lymphadenectomy during primary surgery and adjuvant chemo-radio therapy.

Epithelioid sarcoma is a rare malignant mesenchymal neoplasm (less than 1% of all sarcomas) with epithelioid morphology. Among the 2 subtypes, proximal represents only one-third of cases and commonly involves deep tissues of pelvic region, including the perineum, genital area, and groin, and occurs more frequently in older patients who present a more aggressive course. In the female genital tract, proximal-type epithelioid sarcoma (PES) mainly affects the vulva and is extremely uncommon in the uterus. To our knowledge, only a few cases of PES involving the cervix and uterine body have been previously reported in the literature. We report a 23-year-old woman who presented with abnormal vaginal bleeding. She was found to have a cervical mass, which was resected and diagnosed as a hemangioendothelioma. However, 2 months later, the mass recurred and the histopathological analysis at our institution demonstrated a PES confined to the uterine cervix. It is important to include this neoplasm in the differential diagnosis of epithelioid tumors that can involve the female genital tract because it has a significant impact on prognosis and treatment.

Abstract Purpose. The phase III European Organization for Research and Treatment of Cancer 55874 study has shown that external beam radiotherapy (EBRT) given as adjuvant treatment decreased locoregional recurrences from 40% to 20% in patients (pts) with localized uterine sarcomas (US). No data exist, however, on the place of brachytherapy (BT). Material and Methods. We conducted a single‐center retrospective analysis of pts receiving adjuvant BT of the vaginal vault based on the vaginal mold technique as part of their multimodal adjuvant treatment for a high‐grade US from 1985 to 2015. Treatment characteristics, patterns of relapse, and toxicity were examined. Results. Median follow‐up time was 5.5 years. A total of 98 pts with high‐grade US were identified: 81 leiomyosarcomas and 17 undifferentiated sarcomas. Postoperative chemotherapy was delivered in 53 pts. Median dose of EBRT was 45 Gy in 25 fractions. High‐dose rate, low‐dose rate, and pulsed‐dose rate techniques were used in 66, 31, and 1 pts, respectively. At last follow‐up, six pts (6.1%) experienced a locoregional relapse as first event. The International Federation of Gynecology and Obstetrics stage and the tumor size were associated with a higher probability of local relapse. When focusing on pts with stage I‐III disease, 5‐year overall survival was 77% (95% confidence interval: 67%–87%) and 5‐year survival without locoregional failure was 91% (83%–98%). Toxicities were mild to moderate, with only four acute grade 3 toxicities and two grade 3 late effects. Conclusion. Vaginal vault BT as part of a multimodal adjuvant treatment was associated with a high locoregional control rate and with acceptable side effects in localized high‐grade US. Implications for Practice. This study suggests that an aggressive adjuvant treatment combining chemotherapy and pelvic external beam radiotherapy followed with a brachytherapy of the vaginal vault is associated with a high locoregional control rate and an acceptable toxicity rate in patients with high grade uterine sarcoma. Adding a brachytherapy boost could also allow deescalating the total dose of pelvic external beam radiotherapy, in order to decrease the side effects of adjuvant treatment in these patients without increasing the risk of local relapse. However, the prognosis remains determined by a high frequency of systemic relapses. PMID:28174295

Uterine malformation is a rare deformity in woman, and only a few cases concerning endometrial cancer arising in patients with congenital uterine anomalies have been reported. Herein, we present 3 cases of endometrial cancer with different congenital uterine anomalies, and review studies involving congenital uterine anomalies associated with endometrial cancer in the past 25 years, to identify similarities and differences in clinicopathologic characteristics and prognosis between endometrial cancer associated with uterine anomalies, and normal uterus. Case 1 was a 75-year-old gravida 1, para 0, woman with carcinosarcoma (mixed well-differentiated endometrial adenocarcinoma and undifferentiated sarcoma) of the right cavity (grade III, and at least stage II ) of a uterus didelphys. The tumor recurred within 7 months after surgery, salvage radiotherapy was unsuccessful; the patient died 8 months after the surgery. Case 2 was a 63-year-old gravida 5, para 3, woman with a bicornuate uterus and uterus papillary serous carcinoma of the right horn (grade III, stage IIIC). She did not respond to the chemotherapy post surgery and died within 4 months. Case 3 was a 60-year-old gravida 0, para 0, woman with a complete septate uterus and an oblique vaginal septum of the upper region of the vagina with endometrioid adenocarchcinoma of the left cavity (grade II, stage IA). No adjuvant therapy was administered and the patient had recovered 2 y after the surgery. Clinicians should be aware of the coexistence of uterine malignancies and uterine anomalies in patients presenting with persistent abnormal uterine bleeding, but with negative endometrial biopsy or failed in the operation of endometrial biopsy. In such cases, magnetic resonance imaging has an important role in the diagnosis of both malformation and malignancy, and an exploratory laparotomy should be performed to avoid delaying the diagnosis and treatment of cancers.

In the recent years, angiogenetic inhibitors have emerged for the treatment of several malignancies. In particular, bevacizumab has proved to be effective in many types of cancers (including sarcoma), but the limitations of antiangiogenic therapy have been shown in practice. Here, we sought to review the current evidence on the role and efficacy of bevacizumab in patients affected by uterine leiomyosarcoma. On April 2017, Literature was searched in order to identify studies reporting outcomes of patients affected either by early stage or advanced/recurred uterine leiomyosarcoma undergoing treatment with bevacizumab, alone or in combination with other chemotherapeutic regimens. Searching the literature data of 69 patients affected by metastatic, unresectable uterine leiomyosarcoma were retrieved; on the contrary, no data regarding the use of bevacizumab in patients with early-stage uterine leiomyosarcoma was published. Current evidence suggested that the addiction of bevacizumab to standard treatment modality does not increase grade 3 or worse toxicity (assessed by CTCAE). Pooled data regarding response rate suggested that 35%, 28%, 26% and 11% of patients experienced objective cure (complete + partial response), stable disease, progressive disease and unknown response, respectively. Data from the only one randomized controlled trial suggested that objective cure rate does not differ from standard chemotherapy treatment, thus limiting the indication to add bevacizumab in patients affected by metastatic, unresectable uterine leiomyosarcoma. The current evidence does not justify the use of bevacizumab into clinical practice. Further randomized studies testing the role of bevacizumab are warranted. Copyright © 2018 Elsevier B.V.

Purpose: To report our institutional experience with intraoperative radiotherapy (IORT) as a component of treatment for women with locally advanced or recurrent uterine sarcoma. Methods and Materials: From 1990 to 2010, 16 women with primary (n = 3) or locoregionally recurrent (n = 13) uterine sarcoma received IORT as a component of combined modality treatment. Tumor histology studies found leiomyosarcoma (n = 9), endometrial stromal sarcoma (n = 4), and carcinosarcoma (n = 3). Surgery consisted of gross total resection in 2 patients, subtotal resection in 6 patients, and resection with close surgical margins in 8 patients. The median IORTmore » dose was 12.5 Gy (range, 10-20 Gy). All patients received perioperative external beam radiotherapy (EBRT; median dose, 50.4 Gy; range, 20-62.5 Gy), and 6 patients also received perioperative systemic therapy. Results: Seven of the 16 patients are alive at a median follow-up of 44 months (range, 11-203 months). The 3-year Kaplan-Meier estimate of local relapse (within the EBRT field) was 7%, and central control (within the IORT field) was 100%. No local failures occurred in any of the 6 patients who underwent subtotal resection. The 3-year freedom from distant relapse was 48%, with failures occurring most frequently in the lungs or mediastinum. Median survival was 18 months, and 3-year Kaplan-Meier estimates of cause-specific and overall survival were 58% and 53%, respectively. Three patients (19%) experienced late Grade 3 toxicity. Conclusions: A combined modality approach with perioperative EBRT, surgery, and IORT for locally advanced or recurrent uterine sarcoma resulted in excellent local disease control with acceptable toxicity, even in patients with positive resection margins. With this approach, some patients were able to experience long-term freedom from recurrence.« less

Primary Ewing's sarcoma-primitive neuroectodermal tumor (ES-PNET) of the uterus is an extremely rare malignancy. A 30-year-old Korean woman presented with abnormal uterine bleeding with uterine enlargement. A computed tomography (CT) scan and magnetic resonance imaging (MRI) of the abdomen and pelvis showed a huge uterine mass measuring 18 x 20 x 21 cm, metastasis to both pelvic and para-aortic lymph nodes, and omental infiltration. The pathology report of the uterine mass described a uniformly hypercellular tumor, which was arranged in diffuse solid sheets of uniform, small, rounded, and sometimes spindle-shaped cells, with scanty cytoplasm. Immunohistochemically, the mass tested positive for vimentin, CD99, and chromogranin. The patient received several courses of combination chemotherapy and radiotherapy but died from tumor progression 16 months after the initial diagnosis. This is a rare case of primary uterine ES-PNET in a woman of reproductive age. A review of the literature indicates that primary uterine ES-PNET requires early diagnosis and multimodality treatment including surgery, chemotherapy, and radiotherapy. The behavior of this tumor is potentially aggressive.

Gynecological sarcomas: what's new in 2018, a brief review of published literature.

In this article, we focus on recent published data (2017) on the management of gynecologic sarcomas. The most significant data published in 2017 develop definition of a new molecular subtype of high grade endometrial stromal sarcoma (ESS) using molecular technics added to histological analysis. The identification of a new translocation on presumed uterine leiomyosarcoma (LMS) points to refinement of nosological classification, with fragmentation of even rare tumors into distinct molecular entities: gynecologic sarcomas are now distinguished into distinct entities from a heterogeneous group of tumors. Other articles have discussed the real incidence of unsuspected sarcomas after fibroid mini-invasive surgery and evaluate the risk of relapse and dissemination after morcellation. Among several criteria, preoperative imagery could become a useful tool. For systemic treatment, no clinical trials changing practices were published, only one positive nonrandomized phase II with carboplatin and pegylated liposomal doxorubicin (PLD) in the treatment of uterine sarcomas after the conventional first line, especially in LMSs and ESSs. Many articles were published on this confidential domain in oncology demonstrating interests on rare sarcomas. All specialties were represented in the literature, even though we are still waiting for urgent improvements in early diagnosis and therapeutic strategies to transform the poor prognostic of these tumors.

This project of the International Society for Gynecologic Endoscopy (ISGE) had the objective to review the literature and provide recommendations on the occult sarcoma risk assessment in patients who are candidates for minimally invasive gynecological surgery involving intra-abdominal electromechanical tissue morcellation. The ISGE Task Force for Estimation of the Risk in Endoscopic Morcellation initially defined key topics and clinical questions which may guide a comprehensive preoperative patient assessment. A literature search within the Medline/PubMed and Cochrane Database was carried out using keywords "morcellation", "uterine fibroids", "uterine sarcoma", "myomectomy" and "hysterectomy". Relevant publications (original studies, meta-analyses and previous reviews), written in English and published until May 30th, 2017, were selected and analyzed. Previously emitted statements of 12 recognized professional societies or government institutions and their supporting literature were also studied. For each topic/clinical question, the available information was graded by the level of evidence. The ISGE recommendations were established in accordance with the evidence quality. In the light of available information, 9 recommendations on preoperative clinical, laboratorial and imaging evaluation of the candidates for intracorporeal uterus/leiomyoma morcellation were formulated, mainly based on consensus and expert opinions. There is a lack of high-quality evidence, which does not allow the establishment of strong recommendations. Electromechanical tissue morcellation may be used in gynecological patients who are considered "low risk" upon appropriate preoperative evaluation; however, further studies and prospective data collection are greatly needed to improve sarcoma risk assessment in women with presumed uterine leiomyomas.

PET and PET/computed tomography play a role in the staging, monitoring of response to therapy, and surveillance for cervical and ovarian cancers. Currently, it is also an integral part of the assessment of patients with endometrial cancer and other gynecologic malignancies, such as vaginal and vulvar cancers and uterine sarcomas. In this article, we discuss in detail and highlight the potential role of PET and PET/computed tomography in evaluating these gynecologic malignancies using illustrative cases with relevant imaging findings.

Uterine leiomyosarcomas (ULMS) represent 1.3% of all uterine malignant tumors. Surgery is the curative treatment for patients with early stage disease. In case of advanced, persistent or recurrent tumor, chemotherapy represents the standard of care, but these patients have a poor prognosis. As the results with available therapies are far from being satisfactory, research is focusing on identification of new compounds. In 2012 the Food and Drug Administration (FDA) licensed pazopanib for the treatment of advanced soft-tissue sarcomas failing previous chemotherapy. Areas covered: The aim of this article is to review the literature on the pharmacokinetics, pharmacodynamics, clinical efficacy and safety of the tyrosine kinase inhibitor (TKI), pazopanib in the treatment of ULMS. Expert opinion: The discovery of some relevant signalling pathways in LMS cells led to the development of new targeted drugs with promising results in the management of these tumors. Pazopanib is a multi-target second-generation TKI with activity against growth factors involved in angiogenesis. It has shown promising results both in terms of efficacy and safety, as shown in the EORTC 62043 Study and the PALETTE trial. Further studies are awaited to evaluate its efficacy in uterine leiomyosarcomas.

In the recent decades, laparoscopy has replaced open abdominal procedures in the setting of gynecologic surgery. Extraction of large specimens (e.g., large uteri or myomas) following operative laparoscopy is technically challenging. Technological attempts allow the removal of large and solid pelvic masses via small abdominal incisions (using instruments called morcellators), thus reducing unnecessary laparotomies and improving short-term patients' outcomes. However, morcellation of undiagnosed uterine malignancies may lead to worse survival outcomes. Therefore, the Food and Drug Administration (FDA) warns about the use of power morcellators, thus causing ongoing concerns on the applicability of minimally invasive approaches for myomectomy and the removal of large uteri. In the present review, we sought to assess pro and cons regarding minimally invasive morcellation. This review will discuss the effects of morcellation of undiagnosed uterine malignancies, focusing on possible techniques for preoperative detection of uterine sarcoma and for avoiding intra-abdominal dissemination of potentially malignant tissues. Further efforts are necessary in order to identify tools to make a more accurate and reliable preoperative diagnosis of uterine masses. However, on the light of the current evidence, intra-abdominal morcellation should be banned from clinical practice. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Sixteen women with clinically diagnosed uterine masses were studied by magnetic resonance imaging (MRI). Pelvic study was carried out in the coronal, sagittal and axial planes. Uterine leiomyomas were detected in 12 cases, while the remaining cases were one each of uterine sarcoma, invasive molar pregnancy, cervical malignancy with pyometra and haematometra with congenital cervical stenosis. The uterine origin of the masses could be clearly detected in all patients, as well as the nature of the masses, the presence of degenerative or malignant changes and the nature of the intrauterine fluid. MRI characteristic findings of the studied masses are presented and discussed.

Endometrial stromal tumours revisited: an update based on the 2014 WHO classification.

PubMed

Ali, Rola H; Rouzbahman, Marjan

2015-05-01

Endometrial stromal tumours (EST) are rare tumours of endometrial stromal origin that account for less than 2% of all uterine tumours. Recent cytogenetic and molecular advances in this area have improved our understanding of ESTs and helped refine their classification into more meaningful categories. Accordingly, the newly released 2014 WHO classification system recognises four categories: endometrial stromal nodule (ESN), low-grade endometrial stromal sarcoma (LGESS), high-grade endometrial stromal sarcoma (HGESS) and undifferentiated uterine sarcoma (UUS). At the molecular level, these tumours may demonstrate a relatively simple karyotype with a defining chromosomal rearrangement (as in the majority of ESNs, LGESSs and YWHAE-rearranged HGESS) or demonstrate complex cytogenetic aberrations lacking specific rearrangements (as in UUSs). Herein we provide an update on this topic aimed at the practicing pathologist. Published by the BMJ Publishing Group Limited.

Primary primitive neuroectodermal tumor (PNET) of the female genital tract is rare, and its proper classification remains unclear. The clinical, histologic, and immunophenotypic features as well as EWSR1 rearrangement status of 19 gynecologic PNETs, including 10 ovarian, 8 uterine, and 1 vulvar tumors, are herein reported. Patient age ranged from 12 to 68 years, with a median age of 20 and 51 years among those with ovarian and uterine PNETs, respectively. Morphologic features of central nervous system (CNS) tumors were seen in 15 PNETs, including 9 medulloblastomas, 3 ependymomas, 2 medulloepitheliomas, and 1 glioblastoma, consistent with central PNET. The remaining 4 PNETs were composed entirely of undifferentiated small round blue cells and were classified as Ewing sarcoma/peripheral PNET. Eight PNETs were associated with another tumor type, including 5 ovarian mature cystic teratomas, 2 endometrial low-grade endometrioid carcinomas, and a uterine carcinosarcoma. By immunohistochemistry, 17 PNETs expressed at least 1 marker of neuronal differentiation, including synaptophysin, NSE, CD56, S100, and chromogranin in 10, 8, 14, 8, and 1 tumors, respectively. GFAP was positive in 4 PNETs, all of which were of central type. Membranous CD99 and nuclear Fli-1 staining was seen in 10 and 16 tumors, respectively, and concurrent expression of both markers was seen in both central and Ewing sarcoma/peripheral PNETs. All tumors expressed vimentin, whereas keratin cocktail (CAM5.2, AE1/AE3) staining was only focally present in 4 PNETs. Fluorescence in situ hybridization was successful in all cases and confirmed EWSR1 rearrangement in 2 of 4 tumors demonstrating morphologic features of Ewing sarcoma/peripheral PNET and concurrent CD99 and Fli-1 expression. In conclusion, central and Ewing sarcoma/peripheral PNETs may be encountered in the female genital tract with central PNETs being more common. Central PNETs show a spectrum of morphologic features that overlaps with CNS tumors but lack EWSR1 rearrangements. GFAP expression supports a morphologic impression of central PNET and is absent in Ewing sarcoma/peripheral PNET. Ewing sarcoma/peripheral PNETs lack morphologic features of CNS tumors.

Nuclear texture analysis measures the spatial arrangement of the pixel gray levels in a digitized microscopic nuclear image and is a promising quantitative tool for prognosis of cancer. The aim of this study was to evaluate the prognostic value of entropy-based adaptive nuclear texture features in a total population of 354 uterine sarcomas. Isolated nuclei (monolayers) were prepared from 50 µm tissue sections and stained with Feulgen-Schiff. Local gray level entropy was measured within small windows of each nuclear image and stored in gray level entropy matrices, and two superior adaptive texture features were calculated from each matrix. The 5-year crude survival was significantly higher (P < 0.001) for patients with high texture feature values (72%) than for patients with low feature values (36%). When combining DNA ploidy classification (diploid/nondiploid) and texture (high/low feature value), the patients could be stratified into three risk groups with 5-year crude survival of 77, 57, and 34% (Hazard Ratios (HR) of 1, 2.3, and 4.1, P < 0.001). Entropy-based adaptive nuclear texture was an independent prognostic marker for crude survival in multivariate analysis including relevant clinicopathological features (HR = 2.1, P = 0.001), and should therefore be considered as a potential prognostic marker in uterine sarcomas. © The Authors.

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. We calculated the prevalence and recorded the clinical characteristics of the patients with malignancy after morcellation application. A total of 62 cases were finally pathologically confirmed as malignant postoperatively. Additionally, the medical records of the 62 patients were analyzed in details. Results: The proportion of postoperative malignancy after morcellation application was 0.18% (62/33,723) for patients who underwent laparoscopic myomectomy. Nearly 62.9% (39/62) of patients had demonstrated blood flow signals in the uterine fibroids before surgery. And, 23 (37.1%) patients showed rapid growth at the final preoperative ultrasound. With respect to the pathological types, 38 (61.3%) patients had detectable endometrial stromal sarcoma, 13 (21.0%) had detectable uterine leiomyosarcoma, only 3 (3.2%) had detectable carcinosarcoma, and 5 (8.1%) patients with leiomyoma had an undetermined malignant potential. Conclusions: The proportion of malignancy is low after using morcellation in patients who undergo laparoscopic myomectomy. Patients with fast-growing uterine fibroids and abnormal ultrasonic tumor blood flow should be considered for malignant potential, and morcellation should be avoided. PMID:29133752

Since the safety warning from the US Food and Drug Administration on the use of power morcellators, minimally invasive procedures involving the removal of uterine myomas and large uteri are under scrutiny. Growing evidence suggests that morcellation of undiagnosed uterine malignancies is associated with worse survival outcomes of patients affected by uterine sarcoma. However, to date, only limited data regarding morcellation of low-grade uterine neoplasms are available. In the present article, we reported a case of a (morcellator) port-site implantation of a smooth muscle tumor that occurred 6 years after laparoscopic morcellation of a uterine smooth muscle tumor of uncertain potential. This case highlights the effects of intra-abdominal morcellation, even in low-grade uterine neoplasms. Caution should be used when determining techniques for tissue extraction; the potential adverse consequences of morcellation should be more fully explored. Copyright © 2016 AAGL.

A 46-year-old woman complained of persistent abnormal vaginal bleeding over ten days. Her intrauterine device had been removed two years before. Soon after, she suffered from menorrhagia and metrorrhagia. An incidental finding of severe anemia was also noted. In this admission, our initial T2-weighted magnetic resonance imaging (MRI) revealed a well-demarcated mass predominantly in the uterine cavity. The mass was depicted by an isointense signal relative to the myometrium on T1-weighted images, high signal intensity on T2-weighted images, and slightly heterogeneous enhancement on post-contrast images. The patient refused surgery. After two years, follow-up MRI showed a pedunculated mass protruding into the upper third of the vagina with a stalk connecting to the posterior wall of the uterine cavity, simulating submucosal myoma. Histological diagnosis was compatible with low-grade endometrial stromal sarcoma.

Chromatin organisation affects gene expression and regional mutation frequencies and contributes to carcinogenesis. Aberrant organisation of DNA has been correlated with cancer prognosis in analyses of the chromatin component of tumour cell nuclei using image texture analysis. As yet, the methodology has not been sufficiently validated to permit its clinical application. We aimed to define and validate a novel prognostic biomarker for the automatic detection of heterogeneous chromatin organisation. Machine learning algorithms analysed the chromatin organisation in 461 000 images of tumour cell nuclei stained for DNA from 390 patients (discovery cohort) treated for stage I or II colorectal cancer at the Aker University Hospital (Oslo, Norway). The resulting marker of chromatin heterogeneity, termed Nucleotyping, was subsequently independently validated in six patient cohorts: 442 patients with stage I or II colorectal cancer in the Gloucester Colorectal Cancer Study (UK); 391 patients with stage II colorectal cancer in the QUASAR 2 trial; 246 patients with stage I ovarian carcinoma; 354 patients with uterine sarcoma; 307 patients with prostate carcinoma; and 791 patients with endometrial carcinoma. The primary outcome was cancer-specific survival. In all patient cohorts, patients with chromatin heterogeneous tumours had worse cancer-specific survival than patients with chromatin homogeneous tumours (univariable analysis hazard ratio [HR] 1·7, 95% CI 1·2-2·5, in the discovery cohort; 1·8, 1·0-3·0, in the Gloucester validation cohort; 2·2, 1·1-4·5, in the QUASAR 2 validation cohort; 3·1, 1·9-5·0, in the ovarian carcinoma cohort; 2·5, 1·8-3·4, in the uterine sarcoma cohort; 2·3, 1·2-4·6, in the prostate carcinoma cohort; and 4·3, 2·8-6·8, in the endometrial carcinoma cohort). After adjusting for established prognostic patient characteristics in multivariable analyses, Nucleotyping was prognostic in all cohorts except for the prostate carcinoma cohort (HR 1·7, 95% CI 1·1-2·5, in the discovery cohort; 1·9, 1·1-3·2, in the Gloucester validation cohort; 2·6, 1·2-5·6, in the QUASAR 2 cohort; 1·8, 1·1-3·0, for ovarian carcinoma; 1·6, 1·0-2·4, for uterine sarcoma; 1·43, 0·68-2·99, for prostate carcinoma; and 1·9, 1·1-3·1, for endometrial carcinoma). Chromatin heterogeneity was a significant predictor of cancer-specific survival in microsatellite unstable (HR 2·9, 95% CI 1·0-8·4) and microsatellite stable (1·8, 1·2-2·7) stage II colorectal cancer, but microsatellite instability was not a significant predictor of outcome in chromatin homogeneous (1·3, 0·7-2·4) or chromatin heterogeneous (0·8, 0·3-2·0) stage II colorectal cancer. The consistent prognostic prediction of Nucleotyping in different biological and technical circumstances suggests that the marker of chromatin heterogeneity can be reliably assessed in routine clinical practice and could be used to objectively assist decision making in a range of clinical settings. An immediate application would be to identify high-risk patients with stage II colorectal cancer who might have greater absolute benefit from adjuvant chemotherapy. Clinical trials are warranted to evaluate the survival benefit and cost-effectiveness of using Nucleotyping to guide treatment decisions in multiple clinical settings.

Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare. This study has reported a 33-year-old woman presented with abnormal vaginal discharge. Gynecologic examination revealed a cervical mass with grape- like feature protruding into vagina with posterior- superior vaginal wall involvement. Biopsy has performed and pathologic examination was consistent with embryonal botryoid type rhabdomyosarcoma. She has undergone the staging work up measurements including thoracic computed tomography (CT) scan, abdominopelvic magnetic resonance imaging (MRI), bone scan and bone marrow examination. In exception of abdominopelvic MRI, with 2 suspicious pelvic lymph nodes in addition of cervical mass, all others were normal. Radical hysterectomy with lymph node debulking and ovarian preservation has performed. Final results have shown embryonal botryoid type rhabdomyosarcoma of cervix. ovaries, endometrium, parametrium, and follopian tubes were unremarkable. Pelvic lymph nodes pathology and intraabdominal fluid cytology were negative for malignancy. Lymphovascular invasion was identified. She has advised for adjuvant chemotherapy. This case has reminded that embryonal rhabdomyosarcoma could occur in uncommon site and older female. Longer follow up of these cases has required due to lack of survival data for embryonal rhabdomyosarcoma of this site and age group.

An ongoing debate over the last two decades has focused on whether fertility treatment in women may lead to an increased risk of developing uterine cancer over a period of time. Uterine cancer (including mainly endometrial carcinoma and the less common uterine sarcoma) is the commonest reproductive tract cancer and the fourth commonest cancer in women in the UK. Our objective was to assess the association between fertility drugs used in the treatment of female infertility (both as an independent therapy and during in vitro fertilization cycles) and the development of uterine cancer. A literature search was performed using Medline, Embase, Cochrane Library and Google Scholar databases for comparative studies until December 2014 to investigate a clinical significance of fertility treatment on the incidence of developing uterine cancer. General and MESH search headings, as well as the 'related articles' function were applied. All comparative studies of 'fertility treatment' versus 'non-fertility treatment' reporting the incidence of uterine cancer as an outcome were included. Uterine cancer incorporated the following terms: uterine cancer, uterine body tumours, uterine sarcomas and endometrial cancers. The primary outcome of interest was the uterine cancer incidence in all 'fertility treatment' versus 'non-fertility treatment' patient groups. Secondary outcomes of interest were: (a) uterine cancer incidence in 'IVF' versus 'non-IVF' patient groups; and (b) uterine cancer incidence according to type of fertility drug used. Odds ratio was the summary statistic. Random-effects modelling, graphical exploration and sensitivity analysis were used to evaluate the consistency of the calculated treatment effect. We included six studies in our final analysis, which comprised 776,224 patients in total. Of these, 103,758 had undergone fertility treatment and 672,466 had not. There was 100% agreement between the two reviewers regarding the data extraction. All the studies contained groups that were comparable in age, although the criteria of reporting age varied. Taking all studies into account, the incidence of uterine cancer was 0.14% (150 of 103,758) in the fertility treatment group and 2.22% (14,918 of 672,466) in the non-fertility treatment group. Using the random-effect model to analyze uterine cancer incidence, this difference was not found to be of statistical significance: OR 0.78 (95% CI, 0.39-1.57). The degree of heterogeneity was high (I(2)=68%). The risk for the development of uterine and in particular endometrial cancer posed by infertility and an unopposed oestrogen state is widely recognized. The present analysis aimed to perceive whether standard fertility drugs were also a risk to future uterine cancer development. The treatment does increase the concentrations of unopposed oestrogen for a short periods of time but if successful leads to fertility. This meta-analysis points to a non-deleterious effect of fertility drugs towards the development of uterine cancer, a conclusion strongly supported by our sub-group analysis.

To record and characterize electromyography (EMG) from the uterus and abdominal muscles during the nonlabor to first and second stages of labor and to define relationships to contractions. Nulliparous patients without any treatments were used (n = 12 nonlabor stage, 48 during first stage and 33 during second stage). Electromyography of both uterine and abdominal muscles was simultaneously recorded from electrodes placed on patients' abdominal surface using filters to separate uterine and abdominal EMG. Contractions of muscles were also recorded using tocodynamometry. Electromyography was characterized by analysis of various parameters. During the first stage of labor, when abdominal EMG is absent, uterine EMG bursts temporally correspond to contractions. In the second stage, uterine EMG bursts usually occur at same frequency as groups of abdominal bursts and precede abdominal bursts, whereas abdominal EMG bursts correspond to contractions and are accompanied by feelings of "urge to push." Uterine EMG increases progressively from nonlabor to second stage of labor. (1) Uterine EMG activity can be separated from abdominal EMG events by filtering. (2) Uterine EMG gradually evolves from the antepartum stage to the first and second stages of labor. (3) Uterine and abdominal EMG reflect electrical activity of the muscles during labor and are valuable to assess uterine and abdominal muscle events that control labor. (4) During the first stage of labor uterine, EMG is responsible for contractions, and during the second stage, both uterine and abdominal muscle participate in labor.

The existence of a "high-grade endometrial stromal sarcoma" category of tumors has been a controversial subject owing to, among other things, the difficulty in establishing consistent diagnostic criteria. Currently, the recommended classification for such tumors is undifferentiated uterine/endometrial sarcoma. Interest in this subject has recently increased markedly with the identification of recurrent molecular genetic abnormalities. At Mayo Clinic, a group of neoplasms has been observed that morphologically resemble, either cytologically or architecturally, classic "low-grade" endometrial stromal sarcoma but feature obvious deviations, specifically, 17 tumors with unequivocally high-grade morphology. These high-grade tumors displayed 3 morphologic themes: (1) tumors with a component that is identical to low-grade ESS that transitions abruptly into an obviously higher-grade component; (2) tumors composed exclusively of high-grade cells with uniform nuclear features but with a permeative pattern of infiltration; (3) tumors similar to the second group but with a different, yet characteristic, cytomorphology featuring enlarged round to ovoid cells (larger than those found in low-grade ESS) with smooth nuclear membranes and distinct chromatin clearing but lacking prominent nucleoli. We collected clinicopathologic data, applied immunohistochemical studies, and also tested tumors by fluorescence in situ hybridization for abnormalities in JAZF1, PHF1, YWHAE, and CCND1. Tumors from these 3 groups were found to be immunohistochemically and genetically distinct from one another. Most notable was the fact that category 3 contained all the cases that tested positive for YWHAE rearrangement, did not show any classic translocations for JAZF1, PHF1, or CCND1, often presented at a high stage, and behaved aggressively. This study demonstrates the morphologic, immunophenotypic, and molecular genetic heterogeneity that exists within "undifferentiated endometrial sarcomas" as currently defined and lends credence to the effort of subclassifying some tumors as truly "high-grade endometrial stromal sarcomas." Our study also shows that, in the context of undifferentiated endometrial sarcomas, recognition of cytomorphologic features on routine hematoxylin and eosin-stained sections may be used to select tumors with specific molecular genetic changes-that is, translocations involving YWHAE. Our conclusions will help further efforts towards proper sub-classification of these tumors which will aid in diagnosis and potentially affect clinical management.

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). Besides a papillary architecture serous carcinomas may show solid and glandular features and TP53 immunohistochemistry with an "all or null pattern" assists in the diagnosis of serous carcinoma with ambiguous features. Neuroendocrine neoplasms are categorized in a similar way to the gastrointestinal tract into well differentiated neuroendocrine tumors and poorly differentiated neuroendocrine carcinomas (small cell and large cell types). Leiomyosarcomas of the uterus are typically high grade and characterized by marked nuclear atypia and lively mitotic activity. Low grade stromal neoplasms frequently show gene fusions, such as JAZF1/SUZ12. High grade endometrial stromal sarcoma is newly defined by cyclin D1 overexpression and the presence of the fusion gene YWHAE/FAM22 and must be distinguished from undifferentiated uterine sarcoma. Carcinosarcomas (malignant mixed Mullerian tumors MMMT) show biological and molecular similarities to high-grade carcinomas.

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. The range of EMT scores in UCS was the largest among all tumor types studied via The Cancer Genome Atlas. UCSs shared proteomic features with gynecologic carcinomas and sarcomas with intermediate EMT features. Multiple somatic mutations and copy-number alterations in genes that are therapeutic targets were identified. Copyright © 2017 Elsevier Inc. All rights reserved.

Postirradiation sarcomas are an unusual but well-recognized late effect of cancer therapy. In this article, a fine-needle aspiration (FNA) series of four cases is presented. There were three female patients and one male patient, with an age range of 28-55 yr (mean, 41). Two of the patients were irradiated for uterine cervical carcinoma while the other two received irradiation for malignant lymphoma. The time interval to the development of the postirradiation sarcoma ranged from 10 to greater than 20 yr. There were a postirradiation synovial sarcoma of the buttock region, malignant fibrous histiocytoma of the bone (femur), and rhabdomyosarcoma andmore » angiosarcoma of the retroperitoneum. A spectrum of cytologic findings was encountered, reflecting the specific types of sarcomas. Immunocytochemical studies performed on the aspirated material from the angiosarcoma demonstrated the utility of immunoperoxidase stains for ULEX europaeus agglutinin-1 (UEA-1) and, to a lesser degree, factor VIII-related antigen antibody, confirming the vascular nature of this malignancy. The FNA findings from all four cases demonstrated cytologic features that allowed recognition of this unusual complication of irradiation treatment. This article confirms the utility of FNA cytology in following patients with previous malignancies and differentiating a postirradiation sarcoma from recurrent carcinoma.« less

Ewing's sarcoma is a highly malignant tumour of osseous or non-osseous origin, tremed as extra-skeletal Ewings sarcoma if arising from soft tissue. It is rare occurrence tumor most commonly occurring in paravertebral area, chest wall, head & neck and retroperitoneum. Reporting an interesting case of retroperitoneal Ewing's sarcoma in 39 years old female. Patient had complains of abdominal discomfort & vague pain since 2 months, following weakness in lower limb and loss of weight. On detail history and examination she was further referred to detail pathological and radiological investigations. Haematological profile, renal function test and liver function test were in normal limits. USG abdomen was normal, MRI showed a mass in pelvis retroperitoneum measuring 10x10cms, bilateral ovaries and tubes were normal. Because of retroperitoneal nature of tumor and suspicion of uterine sarcoma, laparotomy was performed. The large retroperitoneal mass adherent to posterior of uterus was excised and send for histopathological diagnosis. On gross and microscopy examination the diagnosis of blue cell tumor with PAS positivity, possibility of extraskeletal Ewing's sarcoma/primitive neuro-ectodermal tumor was made which was further confirmed by immunohistochemistry, positive for S100, Vementin and CD99 and negative for desmin and CK. Confirmed diagnosis help in accurate management and improves survival rate.

To explore the clinicopathologic features, differential diagnosis and therapy of myeloid sarcoma. The clinical data including clinical manifestations, laboratorial tests, histopathologicical examination, immunohistochemistry and clinical prognosis of 10 patients with myeloid sarcoma were analyzed retrospectively. Among 10 patients, 5 male and 5 female, aged 23 to 71 years old (median = 36 years). 2 cases of myeloid sarcoma were secondary from chronic myeloid leukemia, and 1 cases of myeloid sarcoma occurred after the allogeneic hematopoietic stem cell transplantation due to acute myeloid leukemia, and the others lacked the anamnesis of malignancies. The neoplasms occurred at bone, brain, skin, breast, epididymis, uterine cervix, small intestine, ovary and lymph nodes. Microscopically, the tumor cells were round or oval, which infiltrated diffusely or arranged in single-file. The cytoplasm was scarce and immature eosinophils were scattered. The nuclei were round, oval or focally irregular, and the mitosis was visible. The neoplasms were positive for MPO, CD34, CD43, CD45, CD99 and CD117 by immunohistochemical staining. 4 patients progressed into acute myeloid leukemia from 2 to 10 months after the diagnosis of myeloid sarcoma. All of them achieved complete remission after inductive chemotherapy, but 3 patients relapsed from 3 to 12 months after remission and only survived for 14 to 23 months. 4 patients were treated by using chemotherapy before bone marrow abnormality, and with the disease-free survival for 1 to 48 months. Myeloid sarcoma needs to be distinguished from lymphoblastic lymphoma, Burkitt's lymphoma, blastic plasmacytoid dendritic cell neoplasms and so on. The diagnosis and differential diagnosis of myeloid sarcoma are dependent on the pathological and immunohisto-chemical features. The chemotherapy and allogeneic hematopoietic stem cell transplantation of acute myeloid leukemia are the main methods for treatment of myeloid sarcoma.

Neoadjuvant chemotherapy in soft tissue sarcomas: latest evidence and clinical implications

PubMed Central

Pasquali, Sandro; Gronchi, Alessandro

2017-01-01

Soft tissue sarcomas are a rare and multifaceted group of solid tumours. Neoadjuvant chemotherapy is increasingly used to limit loss of function after wide surgical excision with the ultimate aim of improving patient survival. Recently, advances in the identification of effective treatment strategies and improvements in patient risk stratification have been reached. A randomized trial demonstrated that neoadjuvant epirubicin and ifosfamide improves survival of patients affected by five high-risk soft tissue sarcoma histologies of trunk and extremities, including undifferentiated pleomorphic sarcoma, myxoid liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumours, and leiomyosarcoma. Selection of patients for these treatments is expected to be improved by the eighth edition of the American Joint Committee on Cancer (AJCC) TNM staging system, as it tailors T-stage categories on primary tumour site and considers a prognostic nomogram for retroperitoneal sarcoma, which also includes soft tissue sarcoma histology and other patient and tumour features not directly included in the TNM staging. Within this framework, this article will present neoadjuvant treatment strategies for high-risk soft tissue sarcoma, emphasizing the most recent advances and discussing the need for further research to improve the effectiveness of neoadjuvant treatments.

The population-based incidence of sarcoma and its histological subtypes in Germany is unknown. Up-to-date information on a disease with an incidence comparable to other cancer entities is of high public health relevance. The aim of this study was to determine this incidence and to detect significant changes in incidence trends using data from German epidemiological cancer registries. Pooled data from the German Centre for Cancer Registry Data with a primary diagnosis occurring in 2013 were used. To date, this is the latest data on cancer incidence available for Germany. All German cancer registries with sufficient completeness were included (10 out of 11), covering a population of 70.0 million people, representing 87% of the German population. All malignant sarcomas according to the RARECARE Project and the WHO classification 2002 were considered for analysis and, above all, gastrointestinal stromal tumours (GIST) of uncertain behaviour. Sensitivity analysis was performed excluding certain histologies. The analysis included 3404 cases in men and 3442 cases in women diagnosed in 2013. The age adjusted sarcoma incidence (European standard) was 7.4 (men) and 6.6 (women) per 100,000 inhabitants. About 70% of sarcomas were soft tissue sarcomas, about 22% GIST, and about 9% bone sarcomas. The most common histological subtypes besides GIST were fibrosarcomas (14%) and liposarcomas (12%) in men and complex mixed and stromal neoplasms (22%), non-uterine leiomysarcomas (10%) and fibrosarcomas (9%) in women. Considering the trend for the years of diagnosis 2004 to 2013, there was a significant increase in incidence for GIST while the incidence of soft tissue sarcomas (only men) as well as of bone sarcoma stayed constant over time. As to soft tissue sarcoma in women, the incidence stayed constant up to the year 2009 and significantly decreased afterwards. This study is the first detailed analysis of a German-wide population-based sarcoma incidence showing results comparable to the incidence detected in the RARECARE Project.

Laparoscopic power morcellation of presumed fibroids.

Brolmann, Hans A; Sizzi, Ornella; Hehenkamp, Wouter J; Rossetti, Alfonso

2016-06-01

Uterine leiomyoma is a highly prevalent benign gynecologic neoplasm that affects women of reproductive age. Surgical procedures commonly employed to treat symptomatic uterine fibroids include myomectomy or total or sub-total hysterectomy. These procedures, when performed using minimally invasive techniques, reduce the risks of intraoperative and postoperative morbidity and mortality; however, in order to remove bulky lesions from the abdominal cavity through laparoscopic ports, a laparoscopic power morcellator must be used, a device with rapidly spinning blades to cut the uterine tissue into fragments so that it can be removed through a small incision. Although the minimal invasive approach in gynecological surgery has been firmly established now in terms of recovery and quality of life, morcellation is associated with rare but sometimes serious adverse events. Parts of the morcellated specimen may be spread into the abdominal cavity and enable implantation of cells on the peritoneum. In case of unexpected sarcoma the dissemination may upstage disease and affect survival. Myoma cells may give rise to 'parasitic' fibroids, but also implantation of adenomyotic cells and endometriosis has been reported. Finally the morcellation device may cause inadvertent injury to internal structures, such as bowel and vessels, with its rotating circular knife. In this article it is described how to estimate the risk of sarcoma in a presumed fibroid based on epidemiologic, imaging and laboratory data. Furthermore the first literature results of the in-bag morcellation are reviewed. With this procedure the specimen is contained in an insufflated sterile bag while being morcellated, potentially preventing spillage of tissue but also making direct morcellation injuries unlikely to happen.

A 58-year-old, postmenopausal, multiparous woman presented with a chief complaint of abnormal vaginal bleeding. Endometrial cytology was evaluated twice, revealing only squamous epithelial cells both times. Degenerated leiomyoma or uterine sarcoma was suspected from imaging findings, and total abdominal hysterectomy and bilateral salpingo-oophorectomy were therefore performed. However, histopathological examination revealed no signs of malignancy, and the patient was diagnosed as having ichthyosis uteri with uterine leiomyoma. No koilocytosis was evident, and immunostaining for p16 was also negative. Ichthyosis uteri is an extremely rare disease of unknown origin in which squamous metaplasia of the endometrium occurs across a wide area. Although regarded as a benign condition, cases have been reported in which the underlying condition was squamous cell carcinoma or endometrial adenocarcinoma. If ichthyosis uteri is present, a comprehensive approach is required, and the possibility of uterine malignancy should be considered. However, there may be no direct association between the malignant lesions and ichthyosis uteri. © 2016 Japan Society of Obstetrics and Gynecology.

Radium menopause. A long-term follow-up

Ninety-three patients were traced out of 110 who were treated by induction of a radium menopause in 1950 and 1951. The method was very successful, there were no serious postoperative complications and patients suffered neither recurrence of dysfunctional bleeding nor distressing menopausal symptoms. However seven women subsequently developed malignant tumors and six of these involved the genital tract. The fact that two of these were pelvic sarcomas may support the view that pelvic irradiation promotes the development of sarcoma. This, together with the knowledge that women with abnormal bleeding in the 5th and 6th decades already have an increased riskmore » of uterine malignancy, supports the view that radium menopause should be considered only in the treatment of women who are poor surgical risks.

This study was conducted to review the efficacy and safety of Apatinib in stage IV sarcoma patients who failed previous chemotherapy. The clinical information on 16 patients with stage IV sarcomas who failed in prior chemotherapy and subsequently received Apatinib treatment was collected. Apatinib was given 500mg/daily and 4 weeks as a cycle. All patients had at least one measurable extracranial tumor according to Response Evaluation Criteria In Solid Tumors 1.0 criteria. Progression free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR) and treatment-related adverse effects (AEs) were reviewed and evaluated. Patients was administered Apatinib for 0 to 9 cycles with the median of 3.2 cycles. Median follow-up time was 8.4 months (1 to 12 months). Ten of 16 patients received at least 1 complete cycle of Apatinib treatment were eligible for the efficacy analysis. The median PFS was 8.84 months. Two patients achieved partial response (PR) and 6 patients achieved stable disease (SD). Two patients were evaluated as progression disease (PD) and one patient died of disease progression. The ORR was 20.0% (2/10) and the DCR was 80.0% (8/10). The most common grade 3/4 treatment-related AEs were hypertension (18.7%), hand-foot syndrome (12.5%) and proteinuria (6.3%). No drug-related severe AEs occurred. CApatinib treatment in this exploratory study exhibited objective efficacy and manageable toxicity in stage IV sarcoma patients who failed in chemotherapy. This result supports future random controlled trial to further define Apatinib activity in stage IV sarcomas.

The role of radiology in paediatric soft tissue sarcomas

2008-01-01

Abstract Paediatric soft tissue sarcomas (STS) are a group of malignant tumours that originate from primitive mesenchymal tissue and account for 7% of all childhood tumours. Rhabdomyosarcomas (RMS) and undifferentiated sarcomas account for approximately 50% of soft tissue sarcomas in children and non-rhabdomyomatous soft tissue sarcomas (NRSTS) the remainder. The prognosis and biology of STS tumours vary greatly depending on the age of the patient, the primary site, tumour size, tumour invasiveness, histologic grade, depth of invasion, and extent of disease at diagnosis. Over recent years, there has been a marked improvement in survival rates in children and adolescents with soft tissue sarcoma and ongoing international studies continue to aim to improve these survival rates whilst attempting to reduce the morbidity associated with treatment. Radiology plays a crucial role in the initial diagnosis and staging of STS, in the long term follow-up and in the assessment of many treatment related complications. We review the epidemiology, histology, clinical presentation, staging and prognosis of soft tissue sarcomas and discuss the role of radiology in their management. PMID:18442956

Positron emission tomography/computed tomography (PET/CT) involving 18F-fluorodeoxyglucose (FDG) is widely used for systemic cancer and recurrence diagnosis. However, the differential diagnosis of benign and malignant gynaecological tumours according to FDG accumulation is unclear. This study aimed to investigate the intensity of FDG uptake/metabolic activity for the differential diagnosis of benign and malignant gynaecological tumours. This study included seven patients with physiological phenomena, 34 with benign tumours, 13 with borderline malignant tumours and 119 with malignant tumours who underwent 18F-FDG PET/CT. We assessed the maximum standardized uptake value (SUVmax) and determined its utility in the diagnosis of benign and malignant tumours using a receiver operating characteristic (ROC) curve analysis. Among the 63 patients with ovarian tumours, the mean SUVmax of 22 patients with benign ovarian tumours was 2.48 and the mean SUVmax of 41 patients with malignant ovarian tumours was 10.98 (P < 0.001). In the ROC curve analysis, the area under the curve (AUC) was 0.977, with a 95% confidence interval of 0.947-1.000. With a cut-off value of 3.97 for the optimal SUVmax, the sensitivity and specificity were 95.1% and 86.4%, respectively. In addition, the AUC was 0.911 (95% CI: 0.768-1.000) for the assessment of uterine myomas and sarcomas. With a cut-off value of 10.62 for the optimal SUVmax, the sensitivity and specificity were 91.7% and 86.7% respectively. The SUVmax value helps differentiate benign and malignant ovarian tumours, as well as uterine myomas and uterine sarcomas. © 2018 The Royal Australian and New Zealand College of Radiologists.

Surgical staging in early-stage uterine cancer is controversial. Preoperative serum CA-125 may be of clinical value in predicting the presence of extra-uterine disease in patients with apparent early-stage endometrial cancer. Between October 6, 2005, and June 17, 2010, 760 patients were enrolled in an international, multicentre, prospective randomized trial (LACE) comparing laparotomy with laparoscopy in the management of endometrial cancer apparently confined to the uterus. Of these, 657 patients with endometrial adenocarcinoma had a preoperative serum CA-125 value recorded. Multiple cross-validation analysis was undertaken to correlate preoperative serum CA-125 with stage of disease (Stage I vs. Stage II+) after surgery. Patients' median preoperative serum CA-125 was 14 U/ml. A cutoff point of 30 U/ml was associated with the smallest misclassification error, and using this cutoff, 98 patients (14.9%) had elevated CA-125 levels. Of those, 36 (36.7%) had evidence of extra-uterine disease. Of the 116 patients (17.7%) with evidence of extra-uterine disease, 31.0% had an elevated CA-125 level. On univariate and multivariable logistic regression analysis, only preoperative CA-125 level, but no other preoperative clinical characteristics were found to be associated with extra-uterine spread of disease. Utilizing a cutoff point of 30 U/ml achieved a sensitivity, specificity, positive predictive value and negative predictive value of 31.0, 88.5, 36.7 and 85.7%, respectively. Elevated CA-125 above 30 U/ml in patients with apparent early-stage disease is a risk factor for the presence of extra-uterine disease and may assist clinicians in the management of patients with clinical Stage I endometrial cancer.

PET/MRI is an evolving hybrid imaging modality which combines the inherent strengths of MRIs soft-tissue and contrast resolution and PETs functional metabolic capabilities. Bone and soft-tissue sarcoma are a relatively rare tumor entity, relying on MRI for local staging and often on PET/CT for lymph node involvement and metastatic spread evaluation. The purpose of this article is to demonstrate the successful use of PET/MRI in two sarcoma patients. We also use these patients as a starting point to discuss how PET/MRI might be of value in sarcoma. Among its potential benefits are: superior TNM staging than either modality alone, decreased radiation dose, more sensitive and specific follow-up and better assessment of treatment response. These potentials need to be investigated in future PET/MRI soft-tissue sarcoma trials.

When the Food and Drug Administration (FDA) initially reported on the parlous incidence (0.28%) of occult malignancy identified following uterine power morcellation, investigations thereafter documented their particular experience with this surgical procedure. Nevertheless, the precise risk of identifying a sarcoma following uterine morcellation remains indeterminate, primarily due to varying study patient risk factors, diagnostic criteria and operative approach. We retrospectively evaluated subjects who underwent an endoscopic hysterectomy and uterine power morcellation for the treatment of a presumptive, benign indication from January 2006 until December 2015. The primary outcome was the incidence of an occult malignancy. Secondarily, we were interested in characterizing the patients' specific clinical (age, menopausal status, body mass index (BMI)) risk factors within the context of a confirmed malignant or pre-malignant pathology. We identified 281 patients who underwent endoscopic surgery that incorporated uterine morcellation. During the study period, one subject was ultimately diagnosed with a uterine leiomyosarcoma; the overall incidence of occult malignancy was 0.36%. There were also 3 cases of uterine premalignant disease on final pathology (2 patients had complex hyperplasia with or without atypia and 1 subject was diagnosed with a smooth muscle tumor of uncertain malignant potential (an incidence of 1.1%)). We were unable to establish any relationship between patient age, uterine weight, menopausal status or BMI and the incidence of a malignant or pre-malignant pathology (P > 0.05). The rate of occult malignancy in the present investigation was similar to previously documented studies and that which has been reported by the FDA. Additional study of methods in which to enhance preoperative work-up and mitigate the surgical risk for tumor cell dissemination is warranted. Copyright © 2018 IJS Publishing Group Ltd.

2009-01-01

Introduction. Retroperitoneal sarcomas are uncommon large malignant tumors. Methods. Forty-one consecutive patients with localized retroperitoneal sarcoma were retrospectively studied. Results. Median age was 58 years (range 20–91 years). Median tumor size was 17.5 cm (range 4–41 cm). Only 2 tumors were <5 cm. Most were liposarcoma (44%) and high-grade (59%). 59% were stage 3 and the rest was stage 1. Median followup was 10 months (range 1–106 months). Thirty-eight patients had an initial complete resection; 15 (37%) developed recurrent sarcoma and 12 (80%) had a second complete resection. Patients with an initial complete resection had a 5-year survival of 46%. For all patients, tumor grade affected overall survival (P = .006). Complete surgical resection improved overall survival for high-grade tumors (P = .03). Conclusions. Tumor grade/stage and complete surgical resection for high-grade tumors are important prognostic variables. Radiation therapy or chemotherapy had no significant impact on overall or recurrence-free survival. Complete surgical resection is the treatment of choice for patients with initial and locally recurrent retroperitoneal sarcoma. PMID:19826633

To investigate dynamic changes in myometrial thickness during the third stage of labor. Myometrial thickness was measured using ultrasound at one-minute time intervals during the third stage of labor in the mid-region of the upper and lower uterine segments in 151 patients including: women with a long third stage of labor (n = 30), postpartum hemorrhage (n = 4), preterm delivery (n = 7) and clinical chorioamnionitis (n = 4). Differences between myometrial thickness of the uterine segments and as a function of time were evaluated. There was a significant linear increase in the mean myometrial thickness of the upper uterine segments, as well as a significant linear decrease in the mean myometrial thickness of the lower uterine segments until the expulsion of the placenta (p < 0.001). The ratio of the measurements of the upper to the lower uterine segments increased significantly as a function of time (p < 0.0001). In women with postpartum hemorrhage, preterm delivery, and clinical chorioamnionitis, an uncoordinated pattern among the uterine segments was observed. A well-coordinated activity between the upper and lower uterine segments is demonstrated in normal placental delivery. In some clinical conditions this pattern is not observed, increasing the time for placental delivery and the risk of postpartum hemorrhage. © 2015 S. Karger AG, Basel.

PNETs (primitive neuroectodermal tumors) are a family of highly malignant neoplasms characterized by small round cells of neuroepithelial origin. They usually involve bone and soft tissues, and have a higher incidence in childhood. In this case report, we describe the obstetric and oncological outcome of a huge mass diagnosed as a leiomyoma in a 39-year-old pregnant woman who complained of low back pain, dysuria, and urinary frequency at 22 weeks of gestation. During the 25th week of pregnancy, the patient was referred to our hospital at night with severe anemia and suspected hemoperitoneum. She underwent an emergency caesarean section, delivering a female fetus weighing 400 g, with an Apgar score of 7 at 1 minute and 9 at 5 minutes. During surgery, we found a huge uterine sarcoma-like metastatic tumor, invading the pelvic peritoneum and parametria bilaterally; the adnexae seemed disease-free. We performed a type B radical hysterectomy, bilateral salpingo-oophorectomy, pelvic peritonectomy, omentectomy, appendectomy, and excision of a bulky lymph node. Seven days after delivery, staging computed tomography (CT) scan demonstrated a large lombo-aortic lymph node compressing the left renal vein and we completed debulking with a second surgery, including diaphragmatic peritonectomy and excision of a huge lymph node by lombo-aortic lymphadenectomy, requiring partial reconstruction of an infiltrated renal vein. Ten days after the second surgery, echo-color Doppler showed a regular microcirculation in the left kidney. The patient was discharged after 10 days, and the baby after 1 month, both in good health.Histological examination revealed a uterine body cPNET (central primitive neuroectodermal tumor) orienting the clinical management toward chemotherapy with cisplatin and etoposide. PNETs are aggressive neoplasms, usually diagnosed at an advanced stage. Due to their low incidence, universally accepted guidelines are still unavailable. Radical surgery leaving no macroscopic residual disease is mandatory in advanced stages. A good fertility-sparing procedure can be performed only in young women at early stages of disease, when the wish for childbearing is not yet fulfilled. Copyright © 2017 The Authors.

To examine tumor characteristics and survival outcome of women with uterine carcinosarcoma who had a history of tamoxifen use. This is a multicenter retrospective study examining stage I-IV uterine carcinosarcoma cases based on history of tamoxifen use. Patient demographics, tumor characteristics, treatment pattern, and survival outcomes were compared between tamoxifen users and non-users. Sixty-six cases of tamoxifen-related uterine carcinosarcoma were compared to 1009 cases with no history of tamoxifen use. Tamoxifen users were more likely to be older (mean age, 69 versus 64, P<0.001) and had a past history of malignancy (100% versus 12.7%, P<0.001). Tamoxifen-related uterine carcinosarcoma was significantly associated with a higher proportion of stage IA disease (48.4% versus 29.9%) and a lower risk of stage IVB disease (7.8% versus 16.0%) compared to tamoxifen-unrelated carcinosarcoma (P=0.034). Deep myometrial tumor invasion was less common in uterine carcinosarcoma related to tamoxifen use (28.3% versus 48.8%, P=0.002). On univariate analysis, tamoxifen use was not associated with progression-free survival (5-year rates 44.5% versus 46.8%, P=0.48) and disease-specific survival (64.0% versus 59.1%, P=0.39). After adjusting for age, past history of malignancy, stage, residual disease status at surgery, and postoperative treatment patterns, tamoxifen use was not associated with progression-free survival (adjusted-hazard ratio 0.86, 95% confidence interval 0.50 to 1.50, P=0.60) and disease-specific survival (adjusted-hazard ratio 0.68, 95% confidence interval 0.36 to 1.29, P=0.24). Our study suggests that tamoxifen-related uterine carcinosarcoma may have favorable tumor characteristics but have comparable stage-specific survival outcomes compared to tamoxifen-unrelated uterine carcinosarcoma.

Review literature on uterine carcinosarcoma.

Singh, Rajendra

2014-01-01

Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which 'conversion theory' was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

To evaluate concordance (C) between pre-operative hysteroscopic-directed sampling and final pathology in uterine cancers. A retrospective cross-sectional evaluation of prospectively collected data of women who underwent hysterectomy for uterine malignancies and a previous hysteroscopic-guided biopsy was performed. Diagnostic concordance between pre-operative (hysteroscopic biopsy) and postoperative (uterine specimen) histology was evaluated. In endometrioid-endometrial cancers cases Kappa (k) statistics was applied to evaluate agreement for grading (G) between the preoperative and final pathology. A total 101 hysterectomies for uterine malignancies were evaluated. There were 23 non-endometrioid cancers: 7 serous (C:5/7, 71.4%); 10 carcinosarcomas (C:7/10, 70%, remaining 3 cases only epithelial component diagnosed); 3 clear cell (C:3/3, 100%); 3 sarcomas (C:3/3, 100%). In 78 cases an endometrioid endometrial cancer was found. In 63 cases there was a histological C (63/78, 80.8%) between hysteroscopic-guided biopsy and final pathology, while in 15 cases (19.2%) only hyperplasia (with/without atypia) was found preoperatively. Overall accuracy to detect endometrial cancer was 80.2%. In 50 out of 63 endometrial cancers (79.4%) grading was concordant. The overall level of agreement between preoperative and postoperative grading was "substantial" according to Kappa (k) statistics (k 0.64; 95% CI: 0.449-0.83; p < 0.001), as well as for G1 (0.679; 95% CI: 0.432-0.926; p < 0.001) and G3 (0.774; 94% CI: 0.534-1; p < 0.001), while for G2 (0.531; 95% CI: 0.286-0.777; p < 0.001) it was moderate. In our series we found an 80% C between pre-operative hysteroscopic-guided biopsy and final pathology, in uterine malignancies. Moreover, hysteroscopic biopsy accurately predicted endometrial cancer in 80% of cases and "substantially" predicted histological grading. Hysteroscopic-guided uterine sampling could be a useful tool to tailor treatment in patients with uterine malignancies.

Uterine epithelial changes during placentation in the viviparous skink Eulamprus tympanum.

We used scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to describe the complete ontogeny of simple placentation and the development of both the yolk sac placentae and chorioallantoic placentae from nonreproductive through postparturition phases in the maternal uterine epithelium of the Australian skink, Eulamprus tympanum. We chose E. tympanum, a species with a simple, noninvasive placenta, and which we know, has little net nutrient uptake during gestation to develop hypotheses about placental function and to identify any difference between the oviparous and viviparous conditions. Placental differentiation into the chorioallantoic placenta and yolk sac placenta occurs from embryonic Stage 29; both placentae are simple structures without specialized features for materno/fetal connection. The uterine epithelial cells are not squamous as previously described by Claire Weekes, but are columnar, becoming increasingly attenuated because of the pressure of the impinging underlying capillaries as gestation progresses. When the females are nonreproductive, the luminal uterine surface is flat and the microvillous cells that contain electron-dense vesicles partly obscure the ciliated cells. As vitellogenesis progresses, the microvillous cells are less hypertrophied than in nonreproductive females. After ovulation and fertilization, there is no regional differentiation of the uterine epithelium around the circumference of the egg. The first differentiation, associated with the chorioallantoic placentae and yolk sac placentae, occurs at embryonic Stage 29 and continues through to Stage 39. As gestation proceeds, the uterine chorioallantoic placenta forms ridges, the microvillous cells become less hypertrophied, ciliated cells are less abundant, the underlying blood vessels increase in size, and the gland openings at the uterine surface are more apparent. In contrast, the yolk sac placenta has no particular folding with cells having a random orientation and where the microvillous cells remain hypertrophied throughout gestation. However, the ciliated cells become less abundant as gestation proceeds, as also seen in the chorioallantoic placenta. Secretory vesicles are visible in the uterine lumen. All placental differentiation and cell detail is lost at Stage 40, and the uterine structure has returned to the nonreproductive condition within 2 weeks. Circulating progesterone concentrations begin to rise during late vitellogenesis, peak at embryonic Stages 28-30, and decline after Stage 35 in the later stages of gestation. The coincidence between the time of oviposition and placental differentiation demonstrates a similarity during gestation in the uterus between oviparous and simple placental viviparous squamates.

Objective The objective of this study was to evaluate the association between labor dystocia and uterine rupture. Methods We performed a secondary analysis of a multicenter case-control study that included women with single, prior, low-transverse cesarean section who experienced complete uterine rupture during a trial of labor (TOL). For each case, three women who underwent a TOL without uterine rupture were selected as controls. Data were collected on cervical dilatations from admission to delivery. We evaluated the relationship between uterine rupture and labor dystocia according to several criteria, including the World Health Organization's (WHO's) partogram. Results Data were available for 90 cases and 260 controls. Compared with the controls, uterine rupture was associated with less cervical dilatation on admission, slower cervical dilatation in the first stage of labor and longer second stage of labor (all with p < 0.05). Performing cesarean when the labor curve crossed the ACTION line of WHO's partogram or when the second stage was greater than 2 hours could have (1) prevented up to 56% of uterine rupture and (2) reduced the duration of labor in 57% of women with failed TOL. Conclusion Labor dystocia is a significant risk factor for uterine rupture. Labor progression should be assessed regularly in women with prior cesarean.

Histopathological assessment of the tumor grade and cell type is central to the management and prognosis of various gynecological malignancies. Conventional grading systems for squamous carcinomas and adenocarcinomas of the vulva, vagina and cervix are poorly defined. For endometrioid tumors of the female genital tract as well as for mucinous endometrial, ovarian and seromucinous ovarian carcinomas, the 3‑tiered FIGO grading system is recommended. For uterine neuroendocrine tumors the grading system of the gastrointestinal counterparts has been adopted. Uterine leiomyosarcomas are not graded. Endometrial stromal sarcomas are divided into low and high grades, based on cellular morphology, immunohistochemical and molecular findings. A chemotherapy response score was established for chemotherapeutically treated high-grade serous pelvic cancer. For non-epithelial ovarian malignancies, only Sertoli-Leydig cell tumors and immature teratomas are graded. At this time molecular profiling has no impact on the grading of tumors of the female genital tract.

Classification and terminology of non-low-grade endometrial sarcomas, which show significant nuclear atypia, have been controversial. Currently, these tumors seem to be classified all together into "undifferentiated endometrial sarcoma (UES)." However, it remains unclear whether these non-low-grade sarcomas are universally "undifferentiated." We divided these sarcomas morphologically into undifferentiated endometrial sarcoma with nuclear uniformity (UES-U) and undifferentiated endometrial sarcoma with nuclear pleomorphism (UES-P), and compared their molecular genetic and immunohistochemical profiles. Eighteen low-grade endometrial stromal sarcomas (ESS-LG), 7 UES-U, and 6 UES-P were examined. All the patients with ESS-LG were still alive, either with or without disease, whereas 4 of the 5 patients with advanced stage UES-U and all 3 of the patients with advanced stage UES-P had died of the disease. JAZF1-JJAZ1 fusion transcript was detected in 6 (50%) out of 12 ESS-LG and in 1 (33%) of 3 UES-U, whereas it was not detected in any of the cases of UES-P. ESS-LG and UES-U frequently showed positive immunoreaction for estrogen receptor (ESS-LG: 94%, UES-U: 57%) and progesterone receptor (ESS-LG: 94%, UES-U: 57%), whereas all the UES-P were negative for these receptors. Nuclear beta-catenin expression was more frequently recognized in ESS-LG (47%) and UES-U (85%), compared with UES-P (33%). Moreover, nuclear accumulation of p53 and TP53 gene missense mutations were limited to 3 UES-P cases. Our data suggest that UES-U shares some molecular genetic and immunohistochemical characteristics with ESS-LG, but UES-P considerably differs from ESS-LG.

This study was designed to assess the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. One hundred twenty-three nulliparas with a singleton cephalic pregnancy at term were randomized. Standard care was performed in the control group, and uterine fundal pressure by the Labor Assister (Baidy M-420/Curexo, Inc., Seoul, Korea) was utilized in addition to standard care in the active group. The Labor Assister is an inflatable obstetric belts that synchronized to apply uniform fundal pressure during a uterine contraction. The 62 women in the active group spent less time in the second stage of labor when compared to the 61 women in the control group (41.55+/-30.39 min vs. 62.11+/-35.99 min). There was no significant difference in perinatal outcomes between the two groups. In conclusion, the uterine fundal pressure exerted by the Labor Assister reduces the duration of the second stage of labor without attendant complications.

In the seventh edition of the TNM Classification of Malignant Tumours there are several entirely new classifications: upper aerodigestive mucosal melanoma, gastrointestinal stromal tumour, gastrointestinal carcinoid (neuroendocrine tumour), intrahepatic cholangiocarcinoma, Merkel cell carcinoma, uterine sarcomas, and adrenal cortical carcinoma. Significant modifications concern carcinomas of the oesophagus, oesophagogastric junction, stomach, appendix, biliary tract, lung, skin, prostate and ophthalmic tumours, which will be not addressed in this article. For several tumour entities only minor changes were introduced which might be of importance in daily practice. The new classifications and changes will be commented on without going into details.

The aim was to assess the activity of cisplatin (CDDP) in Ewing sarcoma (ES). The study consisted of front-line window therapy with CDDP 120 mg/sqm every 3 weeks for two courses in children and young adults with primary disseminated ES. Response was assessed using the Response Evaluation Criteria in Solid Tumours criteria, and Simon's two-stage design was applied. Twelve consecutive patients were enrolled in stage 1. Only one objective response was observed. Since the target response rate was not achieved, accrual was stopped and CDDP as a single agent in ES was judged unworthy of further assessment. © 2017 Wiley Periodicals, Inc.

The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined. To report a Chilean experience with NSNE tumors evaluated using PET with FDG. Retrospective review of the database of a PET laboratory. Demographic data, indications and metabolic findings were compared with conventional imaging in 88 adults and children with diverse bone and soft tissue sarcomas as well as 24 gastrointestinal stromal tumors (GIST), 6 pleural malignant mesotheliomas in adults, and 9 medulloblastomas in children. FDG showed good concordance with conventional imaging in NSNE tumors. It was helpful for staging, restaging, follow-up after treatment and for the detection of new not previously suspected lesions. PET with FDG could have a prognostic role and help in patient management, mainly in musculoskeletal and high grade or less differentiated sarcomas. In GIST, it was a good tool for immunotherapy control.

A subset of uterine serous carcinoma (USC) may have better clinical behavior bringing up the possibility that there may be morphologic features, which would help in their categorization. The aim of this study is to evaluate the potential use of the MD Anderson Cancer Center 2-tier grading system for ovarian carcinoma in USC. Tumors assigned a combined score included in this analysis were 1) low-grade: tumors without marked atypia and 12 mitoses/10 high power field (HPF) and 2) high grade: tumors with severe nuclear atypia and >12 mitoses/10 HPF. Clinicopathologic parameters evaluated included patients' age, tumor size, myometrial invasion (MI), lymphovascular invasion (LVI), lymph node (LN), FIGO stage, and patient outcome. 140 patients with USC were included, 30 low grade uterine serous carcinoma (LGUSC) and 110 high grade uterine serous carcinoma (HGUSC). Of all parameters only 2 (MI and stage IA) reached statistical significance. 67% of LGUSC cases showed myometrial invasion versus 93.6% HGUSC cases (p = 0.003). A higher percentage of LGUSC (63.3%) versus HGUSC (32.7%) were in stage IA (p = 0.01). However, by multivariate analysis including age, LVI, stage and tumor grade only stage was an independent prognostic factor. The presence of atypia and mitosis across a uterine serous carcinoma is notoriously variable in magnitude and extent, potentially making evaluation of these features difficult and subsequent grading subjective. Our findings thus show that actual prognostic utility of application of MDACC two-tier grading system to uterine serous carcinoma may not be applicable. Copyright © 2013 Elsevier Inc.

Malignant mesonephric adenocarcinoma of the uterine cervix is a rare occurrence with few cases described in the literature. Although surgery seems to be effective in the treatment of early-stage tumor, no cases describing outcomes of locally advanced stage are available. We report the first case of a patient with International Federation of Obstetrics and Gynecologists stage IIB mesonephric adenocarcinoma undergoing neoadjuvant chemotherapy and radical surgery. Despite the inherent limitation of a single description of a case, our experience supports the utilization of neoadjuvant chemotherapy in patients with malignant mesonephric adenocarcinoma of the uterine cervix. Further prospective multi-institutional studies are needed.

Postpartum or peripartum hemorrhage (PPH) is a major cause of maternal death worldwide. Fertility preserving second stage interventions following uterotonic medications may include compression sutures, uterine balloon tamponade and ligation or embolization of arteries. We present a case of PPH where a novel "uterine sandwich" approach (combination of chitosan-covered gauze with intrauterine balloon tamponade) was effectively used to stop further blood loss and prevented more invasive second stage interventions. Furthermore, we present the ultrasonographic image of chitosan-covered gauze in the uterine cavity. Chitosan-covered gauze and intrauterine balloon tamponade are complementary in their mechanism of work, the balloon reducing blood flow into the uterus and the chitosan-covered gauze enhancing the coagulation. This novel "uterine sandwich" approach can be a useful method for fertility preserving management of PPH. Copyright © 2018. Published by Elsevier Ltd.

Clinical practice guidelines for gynecologic cancers have been developed by many organizations. Although these guidelines have much in common in terms of the practice of standard of care for uterine corpus cancer, practice guidelines that reflect the characteristics of patients and healthcare and insurance systems are needed for each country. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to produce the third edition of the guidelines as an advanced form based on evidence-based medicine, considering up-to-date clinical trials and abundant qualified Korean data. These guidelines cover screening, surgery, adjuvant treatment, and advanced and recurrent disease with respect to endometrial carcinoma and uterine sarcoma. The committee members and many gynecologic oncologists derived key questions from the discussion, and a number of relevant scientific literatures were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, together with other details. The objective of these practice guidelines is to establish standard policies on issues in clinical areas related to the management of uterine corpus cancer based on the findings in published papers to date and the consensus of experts as a KSGO Consensus Statement.

Molecular classification of soft tissue sarcomas and its clinical applications

Sarcomas are a heterogeneous group of tumors that are traditionally classified according to the morphology and type of tissue that they resemble, such as rhabdomyosarcoma, which resembles skeletal muscle. However, the cell of origin is unclear in numerous sarcomas. Molecular genetics analyses have not only assisted in understanding the molecular mechanism in sarcoma pathogenesis but also demonstrated new relationships within different types of sarcomas leading to a more proper classification of sarcomas. Molecular classification based on the genetic alteration divides sarcomas into two main categories: (i) sarcomas with specific genetic alterations; which can further be subclassified based on a) reciprocal translocations resulting in oncogenic fusion transcripts (e.g. EWSR1-FLI1 in Ewing sarcoma) and b) specific oncogenic mutations (e.g. KIT and PDGFRA mutations in gastrointestinal stromal tumors) and (ii) sarcomas displaying multiple, complex karyotypic abnormalities with no specific pattern, including leiomyo-sarcoma, and pleomorphic liposarcoma. These specific genetic alterations are an important adjunct to standard morphological and immunohistochemical diagnoses, and in some cases have a prognostic value, e. g., Ewing family tumors, synovial sarcoma, and alveolar rhabdomyosarcoma. In addition, these studies may also serve as markers to detect minimal residual disease and can aid in staging or monitor the efficacy of therapy. Furthermore, sarcoma-specific fusion genes and other emerging molecular events may also represent potential targets for novel therapeutic approaches such as Gleevec for dermatofibrosarcoma protuberans. Therefore, increased understanding of the molecular biology of sarcomas is leading towards development of newer and more effective treatment regimens. The review focuses on recent advances in molecular genetic alterations having an impact on diagnostics, prognostication and clinical management of selected sarcomas. PMID:20490332

Reconstruction after resections for high-grade sarcomas about the knee in children and adolescents is a challenging problem because of the large soft tissue and skeletal defects, the effects of adjuvant therapy, and the potential for long-term use of the limb. One hundred sixteen patients, all 18 years or younger, with osteosarcoma or Ewing's sarcoma located between the middle femur and middle tibia, were treated with chemotherapy, resection, and allograft reconstruction. One hundred three patients with osteosarcoma and 13 patients with Ewing's sarcoma had 105 Stage II and 11 Stage III tumors. There were 72 osteoarticular grafts (39 femur, 33 tibia), 28 intercalary grafts (19 femur), seven allograft-prosthetic composites (all femur,) and nine allograft-arthrodeses (seven femur, two tibia). At latest followup, 49% of all of the allograft reconstructions were rated good or excellent, 14% were rated as fair, and 37% were failures. Sixteen percent had an infection develop. Twenty-seven percent of patients had a fracture, 34% had a nonunion, and 14 patients eventually required amputation. Reconstruction of large bone defects about the knee in young patients who are being treated with chemotherapy is difficult. Although complications significantly affect outcome, allografts are a viable option for reconstruction in children with high-grade sarcomas about the knee.

The aim of this study was to identify whether there was any difference in patient, tumour, treatment or outcome characteristics between patients with skeletal or extra-skeletal Ewing's sarcoma. We identified 300 patients with new primary Ewing's sarcoma diagnosed between 1980 and 2005 from the centres' local database. There were 253 (84%) with skeletal and 47 (16%) with extra-skeletal Ewing's sarcomas. Although patients with skeletal Ewing's were younger (mean age 16.8 years) than those with extra-skeletal Ewing's sarcoma (mean age 27.5 years), there was little difference between the groups in terms of tumour stage or treatment. Nearly all the patients were treated with chemotherapy and most had surgery. There was no difference in the overall survival of patients with skeletal (64%) and extra-skeletal Ewing's sarcoma (61%) (p = 0.85), and this was also the case when both groups were split by whether they had metastases or not. This large series has shown that the oncological outcomes of Ewing's sarcoma are related to tumour characteristics and patient age, and not determined by whether they arise in bone or soft tissue.

This study was designed to investigate the relationship between the estrous cycle phases with uterine bacterial and fungal flora in non-pregnant female rabbits. Thirty laboratory mature multiparous rabbits were used for this purpose. Samples from uterine lavage for culture of bacteria and fungi were collected at different stages of estrous cycle (based on vaginal cytology), and histopathological observations were evaluated based on the scoring system used for defining the infection of the uterus. Various types of bacteria and fungi were isolated from rabbits at all stages of estrous cycle. The widest variety of bacteria and fungi was isolated at Di-estrous stage and the lowest variety was detected at estrous stage. Klebsiella oxytoca as well as yeast have been isolated at all stages of estrous cycle. This study showed that infection with K. oxytoca and yeast had no relationship with different stages of estrous cycle but other bacteria and fungus were associated with one or more stages of the estrous cycle in rabbits.

To compare the incidence of a uterine septum in women with and without endometriosis and if such incidence correlates with the stage of endometriosis Although a correlation between obstructive Mullerian anomalies and endometriosis has been well established, its link with non-obstructive anomalies remains controversial. To elucidate whether there is a correlation between endometriosis and non-obstructive Mullerian anomalies, we conducted this prospective study on all patients admitted to our Reproductive Endocrinology and Infertility surgical service from February 1, 2010 through June 30, 2012. All patients underwent both hysteroscopy and laparoscopy. Surgical indications included: infertility, pain, and/or menorrhagia. The presence or absence of endometriosis and uterine anomalies were recorded immediately after each surgery and subsequently analyzed. Endometriosis was staged according to the r-ASRM Classification and treated by resection and ablation of deep and superficial lesions, respectively. Since uterine septum is the most common Mullerian anomaly, we considered only this anomaly to test the hypothesis that uterine septum may be associated with an increased incidence of endometriosis. Prospective Study. Evidence from a well-designed case-control study (Canadian Task Force classification II-2). University-affiliated tertiary care center. Reproductive aged women admitted to our service for treatment of pelvic pain, abnormal uterine bleeding, and/or infertility. All patients underwent both hysteroscopy and laparoscopy as part of their evaluation and treatment of pelvic pain, abnormal uterine bleeding, and/or infertility. 343 patients were included in the study. The diagnosis of each patient included infertility - 52, pain - 215, both - 30 and other - 46. The diagnosis of septate uterus was made at hysteroscopy when the endometrial cavity was separated by an avascular septum that obscured visualization of both cornua when the hysteroscope was advanced to the mid-uterine segment. The septum was lysed sharply from cornua to cornua restoring normal fundal configuration. In all cases, the septolysis was bloodless, confirming its avascular nature. The overall incidence of uterine septum was 33% in our patient population. In patients with a histologically confirmed diagnosis of endometriosis, the incidence of septum was 37% versus 27% in patients without endometriosis (P = .046). In patients with advanced endometriosis, Stage IV disease, the incidence of septate uterus was 41% (P = .022). The odds ratio of Stage IV endometriosis with a uterine septum was 1.94 (CI 1.09-3.44). The incidence of septate uterus in our population of women with infertility and/or pelvic pain ranges from 27% to 37%, being significantly higher in women with endometriosis and mores so with Stage IV disease. Our data suggests that the presence of a uterine septum may predispose to more advanced disease. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

To examine national imaging strategies regarding the use of F-18-FDG PET-CT in patients with Ewing sarcoma and study factors that might influence the use of PET-CT, such as tumour biology (Picci grade of operation specimen), clinical disease stage and age. We examined the medical records including pathology and imaging of all patients below 30 years diagnosed with Ewing sarcoma in Norway in 2005-2012. Of 61 patients treated at one of the two national sarcoma treatment service centres (Oslo: 35, Bergen: 26), 29 patients had localized disease, 8 had tumour extending to organs nearby and 24 had metastases. Among 35 operated patients with neoadjuvant chemotherapy, 15 had Picci grades II and III (good responders) and 20 grade I (poor responders). We found a significant difference in the use of PET-CT (Oslo/Bergen 0·9 versus 2·0 scans per patient, P = 0·010) and in the use of MRI (Oslo/Bergen: eight versus 13, P = 0·006). No differences were proven for ultrasound, radiography, CT or skeletal scintigraphy. The number of PET-CTs was associated with clinical disease stage at diagnosis (P = 0·041) but not with Picci grade or age. The number of PET studies was not correlated to the number of MR studies. The use of PET-CT in children and young adults diagnosed with Ewing sarcoma in Norway during 2005-2012 at the two national sarcoma treatment service centres differed significantly. The use of PET-CT imaging was related to the clinical disease stage at diagnosis but unrelated to patient age and tumour biology (Picci grade). © 2015 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Prognostic factors and treatment outcomes in surgically-staged non-invasive uterine clear cell carcinoma: a Turkish Gynecologic Oncology Group study

PubMed Central

2017-01-01

Objective To assess the prognosis of surgically-staged non-invasive uterine clear cell carcinoma (UCCC), and to determine the role of adjuvant therapy. Methods A multicenter, retrospective department database review was performed to identify patients with UCCC who underwent surgical treatment between 1997 and 2016 at 8 Gynecologic Oncology Centers. Demographic, clinicopathological, and survival data were collected. Results A total of 232 women with UCCC were identified. Of these, 53 (22.8%) had surgically-staged non-invasive UCCC. Twelve patients (22.6%) were upstaged at surgical assessment, including a 5.6% rate of lymphatic dissemination (3/53). Of those, 1 had stage IIIA, 1 had stage IIIC1, 1 had stage IIIC2, and 9 had stage IVB disease. Of the 9 women with stage IVB disease, 5 had isolated omental involvement indicating omentum as the most common metastatic site. UCCC limited only to the endometrium with no extra-uterine disease was confirmed in 41 women (73.3%) after surgical staging. Of those, 13 women (32%) were observed without adjuvant treatment whereas 28 patients (68%) underwent adjuvant therapy. The 5-year disease-free survival rates for patients with and without adjuvant treatment were 100.0% vs. 74.1%, respectively (p=0.060). Conclusion Extra-uterine disease may occur in the absence of myometrial invasion (MMI), therefore comprehensive surgical staging including omentectomy should be the standard of care for women with UCCC regardless of the depth of MMI. Larger cohorts are needed in order to clarify the necessity of adjuvant treatment for women with UCCC truly confined to the endometrium. PMID:28541637

Neonatal treatment of hamsters with diethylstilbestrol (DES) induces uterine hyperplasia/dysplasia/neoplasia (endometrial adenocarcinoma) in adult animals. We subsequently determined that the neonatal DES exposure event directly and permanently disrupts the developing hamster uterus (initiation stage) so that it responds abnormally when it is stimulated with estrogen in adulthood (promotion stage). To identify candidate molecular elements involved in progression of the disruption/neoplastic process, we performed: (1) immunoblot analyses and (2) microarray profiling (Affymetrix Gene Chip System) on sets of uterine protein and RNA extracts, respectively, and (3) immunohistochemical analysis on uterine sections; all from both initiation stage and promotion stage groups of animals. Here we report that: (1) progression of the neonatal DES-induced hyperplasia/dysplasia/neoplasia phenomenon in the hamster uterus involves a wide spectrum of specific gene expression alterations and (2) the gene products involved and their manner of altered expression differ dramatically during the initiation vs. promotion stages of the phenomenon.

4th Stage Transvaginal omental herniation during VBAC complicated by shoulder dystocia: a unique presentation of uterine rupture

PubMed Central

2013-01-01

Background Uterine rupture is a common complication in women attempting their first virginal birth after caesarean section (VBAC) but the risk diminishes with subsequent VBACs. It occurs in rates of 0.5-9% and is influenced by various factors. Case presentation A unique case of uterine rupture in a Kenyan woman of African descent during a repeat VBAC complicated by shoulder dystocia was discovered during the 4th stage of labour when omentum was noted protruding through the vagina. She had delivered 4 years earlier by caesarean section. Conclusion It is not common to experience uterine rupture among women attempting repeat VBAC. When it occurs, it may not always follow the known pattern intra-partum and is often associated with poor foetal outcome. PMID:23521920

The National Cancer Data Base (NCDB) of the American College of Surgeons gather demographic and survival data on ∼70% of cancers in the USA. We wanted to investigate the demographic and survivorship data on this potentially more representative cohort of patients with soft tissue sarcomas. We selected 34 of the most commonly encountered soft tissue sarcomas reported to the NCDB, provided that each entity contained a minimum of 50 cases. This report summarizes the demographic and survivorship data on 63,714 patients with these 34 histologically distinct soft tissue sarcomas reported to the NCDB from 1998 to 2010. The overall survivorships of these sarcomas were near the lower limits of many prior reports due to the all-inclusive, minimally biased inclusion criteria. The overall best prognosis was Dermatofibrosarcoma NOS (not otherwise specified). (5-year survivorship 92%). The worst prognosis was Dedifferentiated Chondrosarcoma (5-year survivorship 19%). New observations included Biphasic Synovial Sarcoma demonstrating a better 5-year survivorship (65%) compared to spindle-cell synovial sarcoma (56%, P < 0.031) and Synovial Sarcoma, NOS (52%, P < 0.001). The demographic and 2- and 5-year survivorship data for all 34 soft tissue sarcomas are presented herein. This extent of demographic and survival data in soft tissue sarcomas is unprecedented. Because of the large number of cases and the inclusive nature of the NCDB, without restriction to certain stages, categories, or treatments, it is less subject to selection bias. Therefore, these data are thought to be more reflective of the true overall prognosis given the current management of sarcoma across the NCDB contributing sites. PMID:25044961

In patients with soft tissue sarcoma of the wrist and hand, limb salvage operation is extremely challenging for surgeons in attempting a complete tumor resection with negative surgical margins. In this study, we report four patients with soft tissue sarcoma of the wrist and hand treated by limb salvage operation with intraoperative extracorporeal autogenous irradiated tendon grafts. The patients were all male, and the mean age at the time of surgery was 45 years. Histological diagnoses included clear cell sarcoma in two patients, synovial sarcoma in one, and angiosarcoma in one. All four patients had high grade tumors, wherein three had American Joint Committee on Cancer (AJCC) stage III disease and one with AJCC stage IV disease. The tumors were resected en bloc with involved tendons. The tendons were isolated from the resected tissues, irradiated ex vivo, and re-implanted into the host tendons. In one patient, the bone was resected additionally because of tumor invasion to the bone. Hand function was evaluated using Musculoskeletal Tumor Society (MSTS) rating system. Of the four patients, three died of distant metastatic disease. The remaining patient lives and remains disease-free. The mean follow-up period was 33 months. One patient had local recurrence outside the irradiated graft at 20 months after surgery. The functional rating was 22. Lower scores were seen in patients with reconstruction of flexor tendons than extensor tendons. Limb salvage operation with intraoperative extracorporeal autogenous irradiated tendon grafts is an acceptable method in selected patients with soft tissue sarcoma of the wrist and hand.

2009-02-01

In high-grade musculoskeletal sarcomas, adjuvant chemotherapy is often performed to prevent distant metastases. As the efficacy of chemotherapy varies according to the histological type of sarcoma, its indication is determined according to the histological type and the stage. Prognoses are poor in patients with osteosarcoma, Ewing's sarcoma, or rhabdomyosarcoma, when surgery alone is performed. However, because these sarcomas are chemosensitive, their prognoses are improved with adjuvant chemotherapy, so it is absolutely necessary. Drugs commonly used for osteosarcoma include adriamycin, cisplatin, methotrexate, vincristine, and ifosfamide. For Ewing's sarcoma and rhabdomyosarcoma, vincristine, actinomycin-D, cyclophosphamide, etoposide, and ifosfamide are commonly used. On the other hand, the efficacy of chemotherapy is unclear in most of the non-round cell sarcomas, e. g., malignant fibrous histiocytoma, pleomorphic liposarcoma, and leiomyosarcoma, so adjuvant chemotherapy is relatively indicated and often performed preoperatively. The efficacy is evaluated by reduction of the tumor volume as a surrogate marker. Postoperative chemotherapy is performed when the preoperative chemotherapy is effective. Nowadays, several kinds of antitumor agents are usually used for non-round cell sarcomas, and many authors have reported various kinds of regimens and their clinical results. Among them, the key drugs are adriamycin and ifosfamide. Recently, taxanes and gemcitabine are sometimes used. For chemoresistant sarcomas, e. g., chondrosarcoma, chordoma, alveolar soft part sarcoma, chemotherapy is rarely indicated, even if the tumor is histologically high grade and large. Low-grade musculoskeletal sarcomas, e. g., low-grade chondrosarcoma, central low-grade osteosarcoma, parosteal osteosarcoma, well-differentiated liposarcoma, and dermatofibrosarcoma protuberans, are well cured only by surgical excision, and adjuvant chemotherapy is therefore not indicated. Superficially-located, small-size non-round cell sarcomas, even though histologically high grade, are well healed only by surgical excision, and adjuvant chemotherapy is rarely indicated.

Ewing's sarcoma (or peripheral neuroectodermal tumour) is generally found in bone tissue, and a primary dermal site is extremely rare. We report a case of primary cutaneous Ewing's sarcoma in a 21-year-old woman. A 21-year-old woman presented with a scapular lesion that had been slowly developing for one year. The 1-cm lesion was removed and histological examination showed proliferation of small round cells in the dermis. Immunostaining revealed cytoplasmic membrane expression of CD99 and a negative immunoprofile for other small round-cell tumors. Ewing's sarcoma fusion gene transcripts were detected using fluorescence in situ hybridization (FISH). A staging examination revealed no other abnormalities. It was decided to treat the lesion as for osseous Ewing's sarcoma with wide resection followed by systemic adjuvant chemotherapy. Cutaneous Ewing's sarcoma raises concerns about diagnosis and treatment. Owing to the non-specificity of its clinical presentation, histology and immunoprofile, diagnosis of superficial Ewing's sarcoma is difficult and numerous differential diagnoses must be considered. When dealing with a surface tumour, the diagnosis of cutaneous Ewing's sarcoma must be considered. CD99 immunostaining and molecular testing for evidence of EWSR1 rearrangement are useful investigations to confirm the diagnosis. Furthermore, modalities of treatment must be carefully discussed. Cutaneous Ewing's sarcoma is currently treated in the same way as osseous Ewing's sarcoma (wide surgical excision, adjuvant radiotherapy when surgical margins are unsatisfactory, systemic adjuvant chemotherapy, and, in some cases, bone marrow transplant). However, some studies show a more favourable prognosis for cutaneous Ewing's sarcoma than for osseous Ewing's sarcoma. We may thus ask whether such aggressive multimodal treatment is needed.

Ewing's sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG (Vigil) vaccine, in which 12 advanced stage Ewing's patients were safely treated and went on to achieve a predicted immune response (IFNγ ELISPOT). We describe follow-up through year 3 of a prospective, nonrandomized study comparing an expanded group of Vigil-treated advanced disease Ewing's sarcoma patients (n = 16) with a contemporaneous group of Ewing's sarcoma patients (n = 14) not treated with Vigil. Long-term follow-up results show a survival benefit without evidence of significant toxicity (no ≥ grade 3) to Vigil when administered once monthly by intradermal injection (1 × 10e(6) cells/injection to 1 × 10e(7) cells/injection). Specifically, we report a 1-year actual survival of 73% for Vigil-treated patients compared to 23% in those not treated with Vigil. In addition, there was a 17.2-month difference in overall survival (OS; Kaplan-Meier) between the Vigil (median OS 731 days) and no Vigil patient groups (median OS 207 days). In conclusion, these results supply the rational for further testing of Vigil in advanced stage Ewing's sarcoma.

The impact of adherence to clinical practice guidelines (CPGs) for loco-regional treatment (i.e. surgery and radiotherapy) and chemotherapy on local disease control and survival in sarcoma patients was investigated in a European study conducted in an Italian region (Veneto). The completeness of the adherence to the Italian CPGs for sarcomas treatment was assessed by comparing the patient's charts and the CPGs. Propensity score-adjusted multivariate survival analysis was used to assess the impact of CPGs adherence on patient clinical outcomes. A total of 151 patients were included. Adherence to CPGs for loco-regional therapy and chemotherapy was observed in 106 out of 147 (70.2%) and 129 out of 139 (85.4%) patients, respectively. Non-adherence to CPGs for loco-regional treatment was independently associated with AJCC stage III disease [odds ratio (OR) 1.77, P = 0.011] and tumor-positive excision margin (OR 3.55, P = 0.003). Patients not treated according to the CPGs were at a higher risk of local recurrence [hazard ratio (HR) 5.4, P < 0.001] and had a shorter sarcoma-specific survival (HR 4.05, P < 0.001), independently of tumor stage. Incomplete adherence to CPGs for loco-regional treatment of sarcomas was associated with worse prognosis in patients with non-metastatic tumors.

Chronic lymphocytic leukaemia often has a clinical presentation characterised by increased neoplastic lymphocytes which are mostly mature looking due to B lymphocytes. Increased secondary cancer prevalence has been detected among patients with chronic lymphocytic leukaemia diagnosis. In this report, we present three chronic lymphocytic leukaemia patients who developed secondary rare cancers during their follow-up at our clinic. Case 1: A 54-year-old female patient was diagnosed with stage I chronic lymphocytic leukaemia in 2003 and was diagnosed with Merkel cell carcinoma in February 2013. Case 2: A 66-year-old male patient was diagnosed with stage II chronic lymphocytic leukaemia in 2009 and was diagnosed with Kaposi's sarcoma in March 2013. Case 3: A 77-year-old male patient was diagnosed with stage I chronic lymphocytic leukaemia in 2006 and was diagnosed with Kaposi's sarcoma in 2011. In conclusion, secondary cancers are observed in patients diagnosed with chronic lymphocytic leukaemia. Therefore, follow-up of chronic lymphocytic leukaemia requires additional attention in this context. © The Author(s) 2016.

Uterine atony: definition, prevention, nonsurgical management, and uterine tamponade.

PubMed

Breathnach, Fionnuala; Geary, Michael

2009-04-01

Uterine atony, or failure of the uterus to contract following delivery, is the most common cause of postpartum hemorrhage. This review serves to examine the prevention and treatment of uterine atony, including risk-factor recognition and active management of the third stage of labor. A range of uterotonic agents will be compared for efficacy, safety, and ease of administration. Oxytocin and ergot alkaloids represent the cornerstone of uterotonic therapy, while prostaglandin therapy has been studied more recently as an attractive alternative, particularly for resource-poor settings. Newer supplementary medical therapies, such as recombinant factor VII and hemostatic agents, and adjunctive nonsurgical methods aimed at achieving uterine tamponade will be evaluated.

The objective of this study was to identify detailed fertility traits in dairy and beef cattle from transrectal ultrasonography records and quantify the associated risk factors. Data were available on 148 947 ultrasound observations of the reproductive tract from 75 949 cows in 843 Irish dairy and beef herds between March 2008 and October 2012. Traits generated included (1) cycling at time of examination, (2) cystic structures, (3) early ovulation, (4) embryo death and (5) uterine score; the latter was measured on a scale of 1 (good) to 4 (poor) characterising the tone of the uterine wall and fluid present in the uterus. After editing, 72,773 records from 44,415 dairy and beef cows in 643 herds remained. Factors associated with the logit of the probability of a positive outcome for each of the binary fertility traits were determined using generalised estimating equations; linear mixed model analysis was used for the analysis of uterine score. The prevalence of cycling, cystic structures, early ovulation and embryo death was 84.75%, 3.87%, 7.47% and 3.84%, respectively. The occurrence of the uterine heath score of 1, 2, 3 and 4 was 70.63%, 19.75%, 8.36% and 1.26%, respectively. Cows in beef herds had a 0.51 odds (95% CI=0.41 to 0.63, P<0.001) of cycling at the time of examination compared with cows in dairy herds; stage of lactation at the time of examination was the same in both herd types. Furthermore, cows in dairy herds had an inferior uterine score (indicating poorer tone and a greater quantity of uterine fluid present) compared with cows in beef herds. The likelihood of cycling at the time of examination increased with parity and stage of lactation, but was reduced in cows that had experienced dystocia in the previous calving. The presence of cystic structures on the ovaries increased with parity and stage of lactation. The likelihood of embryo/foetal death increased with parity and stage of lactation. Dystocia was not associated with the presence of cystic structures or embryo death. Uterine score improved with parity and stage of lactation, while cows that experienced dystocia in the previous calving had an inferior uterine score. Heterosis was the only factor associated with increased likelihood of early ovulation. The fertility traits identified, and the associated risk factors, provide useful information on the reproductive status of dairy and beef cows.

We performed preoperative intraarterial chemotherapy in twenty cases of uterine cervical adenocarcinoma (stage Ib: 2, II: 15, III: 3) and evaluated the efficacy of this therapy. The dosages used were 75-120 mg of CDDP, 10-20 mg of MMC and 30-60 mg of EPIR. These drugs were administered by intraarterial one-shot infusion twice every three weeks. In five cases, complete response (CR) of the primary lesion was confirmed by histologic examination. There were no cases of CR inpatients with well differentiated adenocarcinoma. Stage reduction was achieved in all cases except three. In all but one case, more than 50% volume reduction was recognized on MR images. These results were not significantly different from those in cases of uterine cervical squamous cell carcinoma in which we performed this therapy. Therefore, we concluded that intraarterial chemotherapy is highly effective and should be carried out as neoadjuvant therapy for advanced uterine cervical adenocarcinoma.

Ewing's sarcoma of the cervix, a diagnostic dilemma: a case report and review of the literature.

Ewing's sarcoma belongs to a spectrum of neoplastic diseases known as Ewing's family of tumors. This family of tumors is usually seen in osseous sites. Ewing's sarcoma of the cervix is extremely rare, with only 18 cases reported in the English literature. The immunohistochemical profile of Ewing's sarcoma overlaps with other malignancies like small cell carcinoma. The rarity and complex pathologic picture of Ewing's sarcoma of the cervix creates the potential for misdiagnosis. Hence, we believe this case needs to be reported to add to the available literature. A 49-year-old white Caucasian woman presented with vaginal bleeding. A pelvic examination revealed a cystic lesion arising from her cervix. Examination of a biopsy specimen revealed a poorly differentiated neoplasm, with sheets of small hyperchromatic cells, staining weakly for neuroendocrine markers. She was diagnosed with small cell carcinoma and started on concurrent chemotherapy and radiation. However, additional positive immunostaining for CD99 was strongly suggestive of Ewing's sarcoma. Fluorescence in situ hybridization revealed ESWR1 gene rearrangement, confirming Ewing's sarcoma. Our patient underwent surgery, which confirmed stage IIB Ewing's sarcoma. She received adjuvant chemotherapy but died from progressive metastatic disease after four cycles. With early diagnosis and appropriate treatment, Ewing's sarcoma of the cervix can be a potentially curable disease. However, owing to overlapping clinical and histopathological features, the diagnosis poses a challenge to oncologists and pathologists. This article guides pathologists to consider Ewing's sarcoma in the differential diagnosis of small cell carcinoma with weak staining for neuroendocrine markers. This literature review will benefit oncologists encountering this rare entity.

Metastatic malignant melanomas to the uterus are extremely rare; to our knowledge, no more than 13 cases have been reported to date. A 44-years-old multigravida woman presented with a black and irregular surface mass at medial aspect of left thigh. There was also an enlarged left groin node. Wide excision with lymph node dissection revealed malignant melanoma. Further examination found a huge pelvic mass with left deep vein thrombosis consequent by pressure effect. Chest and complete abdominal computed tomography revealed an enlarged, fibroid uterus with pressure effect at left common iliac vein. A total abdominal hysterectomy and bilateral adnexectomy were performed. Intra-operative finding was scattered hyperpigment spots at surface of the uterus and its tumor Histopathological report showed metastatic malignant melanoma involving myometrium and uterine serosa. Diagnosis of stage IV malignant melanoma (uterine metastasis) was achieved. The patient was counseled about her diagnosis, stage, prognosis and further treatment. Uterine metastatic malignant melanoma was a rare condition. This report represents the first case of a cutaneous malignant melanoma involving a uterine leiomyoma in Thailand.

To investigate the effect of patient-controlled epidural analgesia (PCEA) on uterine electromyography (EMG) activity in term pregnant women during labor. Nulliparous pregnant women in spontaneous term labor (N = 30) were enrolled (PCEA group, n = 20 and control group, n = 10). Five time periods (30 minutes each) were defined for noninvasive abdominal recordings and analysis of uterine EMG activity, that is, period I: before PCEA treatment with 2-cm cervical dilation; periods II to IV: each period successively at 30, 60, and 120 minutes after PCEA; and period V: second stage of labor with cervix at 10 cm dilation. Control patients without PCEA were monitored during the same times. The number of bursts/30 min, power density spectrum peak frequency, mean amplitude, and duration of uterine EMG bursts were measured to assess uterine EMG activity. Maternal, fetal, and labor characteristics were also recorded. Data were analyzed by analysis of variance followed by other tests. Electromyography parameters are significantly lower (P < .001) after PCEA (periods II to IV) compared to controls but similar between groups by period V (P > .05). Also, patients with PCEA have a slower rate of cervical dilation (P < .003, period IV only) and longer labor in both stage 1 and stage 2 (P < .05). All patients have similar (P > .05) positive labor outcomes. Patient-controlled epidural analgesia initially suppresses uterine EMG and slows cervical dilation thereby prolonging labor. However, the EMG activity recovers with labor progress with no effects on delivery outcomes. © The Author(s) 2015.

To evaluate obstetric outcomes in women undergoing a trial of labor (TOL) after a previous cesarean for dystocia in second stage of labor. A retrospective cohort study of women with one previous low transverse cesarean undergoing a first TOL was performed. Women with previous cesarean for dystocia in first stage and those with previous dystocia in second stage were compared with those with previous cesarean for nonrecurrent reasons (controls). Multivariable regressions analyses were performed. Of 1655 women, those with previous dystocia in second stage of labor (n = 204) had greater risks than controls (n = 880) to have an operative delivery [odds ratio (OR): 1.5; 95% confidence intervals (CI) 1.1 to 2.2], shoulder dystocia (OR: 2.9; 95% CI 1.1 to 8.0), and uterine rupture in the second stage of labor (OR: 4.9; 95% CI 1.1 to 23), and especially in case of fetal macrosomia (OR: 29.6; 95% CI 4.4 to 202). The median second stage of labor duration before uterine rupture was 2.5 hours (interquartile range: 1.5 to 3.2 hours) in these women. Previous cesarean for dystocia in the second stage of labor is associated with second-stage uterine rupture at next delivery, especially in cases of suspected fetal macrosomia and prolonged second stage of labor.

The AJCC 8th Edition Staging System for Soft Tissue Sarcoma of the Extremities or Trunk: A Cohort Study of the SEER Database.

PubMed

Cates, Justin M M

2018-02-01

Background: The AJCC recently published the 8th edition of its cancer staging system. Significant changes were made to the staging algorithm for soft tissue sarcoma (STS) of the extremities or trunk, including the addition of 2 additional T (size) classifications in lieu of tumor depth and grouping lymph node metastasis (LNM) with distant metastasis as stage IV disease. Whether these changes improve staging system performance is questionable. Patients and Methods: This retrospective cohort analysis of 21,396 adult patients with STS of the extremity or trunk in the SEER database compares the AJCC 8th edition staging system with the 7th edition and a newly proposed staging algorithm using a variety of statistical techniques. The effect of tumor size on disease-specific survival was assessed by flexible, nonlinear Cox proportional hazard regression using restricted cubic splines and fractional polynomials. Results: The slope of covariate-adjusted log hazards for sarcoma-specific survival decreases for tumors >8 cm in greatest dimension, limiting prognostic information contributed by the new T4 classification in the AJCC 8th edition. Anatomic depth independently provides significant prognostic information. LNM is not equivalent to distant, non-nodal metastasis. Based on these findings, an alternative staging system is proposed and demonstrated to outperform both AJCC staging schemes. The analyses presented also disclose no evidence of improved clinical performance of the 8th edition compared with the previous edition. Conclusions: The AJCC 8th edition staging system for STS is no better than the previous 7th edition. Instead, a proposed staging system based on histologic grade, tumor size, and anatomic depth shows significantly higher predictive accuracy, with higher model concordance than either AJCC staging system. Changes to existing staging systems should improve the performance of prognostic models. Until such improvements are documented, AJCC committees should refrain from modifying established staging schemes. Copyright © 2018 by the National Comprehensive Cancer Network.

Operative resection remains the definitive curative therapy for retroperitoneal sarcoma. Data published recently show a correlation between improved outcomes for complex oncologic operations and treatment at academic centers. For large retroperitoneal sarcomas, operative resection can be complex and require multidisciplinary care. We hypothesized that survival rates vary between type of treating center for patients undergoing resection for retroperitoneal sarcoma. Patients with stage I to III nonmetastatic retroperitoneal sarcomas who underwent operative resection were identified from the National Cancer Database during the years 2004-2013. Treating centers were categorized as academic cancer centers or community cancer centers. Overall survival was analyzed by log-rank test and graphed using Kaplan-Meier method. A total of 2,762 patients were identified. A majority of patients (59.4%, n = 1,642) underwent resection at an academic cancer centers. Median age at diagnosis was 63 years old. Neoadjuvant radiotherapy was more common at academic cancer centers, while adjuvant radiotherapy was more common at community cancer centers. Improved overall survival was seen at academic cancer centers across all stages compared with community cancer centers (P = .014) but, after multivariable Cox regression analysis, was not a significant independent predictor of survival (hazard ratio = 0.91, 95% confidence interval, 0.79-1.04, P = .171). Academic cancer centers exhibited a greater rate of R0 resection (55.9% vs 47.0%, P < .001) and a lesser odds of positive margins (odds ratio 0.83, 95% confidence interval, 0.69-0.99, P = .044) after multivariable logistic regression. Resection for retroperitoneal sarcoma performed at academic cancer centers was an independent predictor of margin-negative resection but was not a statistically significant factor for survival. This observation suggests that site of care may contribute to some aspect of improved oncologic resection for retroperitoneal sarcoma. Copyright © 2017 Elsevier Inc. All rights reserved.

Lymph node metastases are an important cause of treatment failure for pediatric and adolescent/young adult (AYA) sarcoma patients. Nodal sampling is recommended for certain sarcoma subtypes that have a predilection for lymphatic spread. Sentinel lymph node biopsy (SLNB) may improve the diagnostic yield of nodal sampling, particularly when single-photon emission computed tomography/computed tomography (SPECT-CT) is used to facilitate anatomic localization. Functional imaging with positron emission tomography/computed tomography (PET-CT) is increasingly used for sarcoma staging and is a less invasive alternative to SLNB. To assess the utility of these 2 staging methods, this study prospectively compared SLNB plus SPECT-CT with PET-CT for the identification of nodal metastases in pediatric and AYA patients. Twenty-eight pediatric and AYA sarcoma patients underwent SLNB with SPECT-CT. The histological findings of the excised lymph nodes were then correlated with preoperative PET-CT imaging. A median of 2.4 sentinel nodes were sampled per patient. No wound infections or chronic lymphedema occurred. SLNB identified tumors in 7 of the 28 patients (25%), including 3 patients who had normal PET-CT imaging of the nodal basin. In contrast, PET-CT demonstrated hypermetabolic regional nodes in 14 patients, and this resulted in a positive predictive value of only 29%. The sensitivity and specificity of PET-CT for detecting histologically confirmed nodal metastases were only 57% and 52%, respectively. SLNB can safely guide the rational selection of nodes for biopsy in pediatric and AYA sarcoma patients and can identify therapy-changing nodal disease not appreciated with PET-CT.

The aim of this study was to evaluate the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. Between July 2009 and December 2010, 188 nulliparous women with a singleton pregnancy at term were enrolled and only one dropped. The participants were randomized to receive either standard care (control group, n = 91) or uterine fundal pressure by the Labor Assister (Baidy M-520/Curexo, Inc., Seoul, Korea; active group, n = 97) during the second stage of labor in addition to standard care. The Labor Assister is an inflatable obstetric belt that is synchronized to apply constant fundal pressure during a uterine contraction. The primary endpoint was duration of the second stage of labor in women who delivered vaginally (control, n = 80 versus active, n = 93). It was not analyzed in women who delivered by cesarean section (n = 14) and delivered precipitously (n = 1). The secondary outcomes are perinatal outcomes and perineal laceration. Participants received patient-controlled epidural analgesia. The 93 women in the active group spent less time in the second stage of labor when compared to the 80 women in the control group (46.51 ± 28.01 min versus 75.02 ± 37.48 min, p < 0.001). There was no significant difference in perinatal outcomes and perineal laceration between the two groups. The uterine fundal pressure exerted by the inflatable obstetric belt reduces the duration of the second stage of labor without complications in nulliparous women who receive patient-controlled epidural analgesia.

The uterine transplant is an innovative surgical procedure whereby a healthy uterus is transplanted into a woman with uterine factor infertility (UFI) for the purpose of procreation. Twelve uterine transplants have been attempted in the world in the last two decades, and five have led to viable births. While uterine transplantation is still in its experimental stages, it remains unclear whether Canadian centres plan to attempt the procedure in the near future. Herein, I raise several observations that are specific to the Canadian setting and apply the Montreal Criteria for the Ethical Feasibility of Uterine Transplantation to determine whether there is fertile ground for a uterine transplantation program to be adopted in Canada.

Puerperal uterine inversion is a rare and potentially life-threatening complication of a mismanaged third stage of labour. Early diagnosis is mandatory for proper management of the patient. Complete uterine inversion is a clinical diagnosis. However, incomplete uterine inversion is difficult to identify and warrants further workup. Sonographic evaluation, although a bedside procedure, may be confusing. The conspicuity of findings is much greater on MR examination than on ultrasound. Only a few diagnostic imaging findings in uterine inversion have been described in previous reports. We present the case of a 26-year-old woman who had a full-term vaginal delivery and presented after 20 days with acute urinary retention and mild vaginal bleeding. She was diagnosed as a case of neglected subacute incomplete uterine inversion. Both greyscale and Doppler sonographic and MR features of the case are described with an emphasis on better delineation of uterine and adnexal anatomy on MR imaging.

Worldwide induction and cesarean delivery rates have increased rapidly, with consequences for subsequent pregnancies. The majority of intrapartum cesarean deliveries are performed for failure to progress, typically in nulliparous women at term. Current uterine registration techniques fail to identify inefficient contractions leading to first-stage labor arrest. An alternative technique, uterine electromyography has been shown to identify inefficient contractions leading to first-stage arrest of labor in nulliparous women with spontaneous onset of labor at term. The objective of this study was to determine whether this finding can be reproduced in induction of labor. Uterine activity was measured in 141 nulliparous women with singleton term pregnancies and a fetus in cephalic position during induced labor. Electrical activity of the myometrium during contractions was characterized by its power density spectrum. No significant differences were found in contraction characteristics between women with induced labor delivering vaginally with or without oxytocin and women with arrested labor with subsequent cesarean delivery. Uterine electromyography shows no correlation with progression of labor in induced labor, which is in contrast to spontaneous labor. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Osteosarcoma is the most frequent malignant bone neoplasm, followed by chondrosarcoma and Ewing sarcoma. The diagnosis of bone neoplasms is generally made through histological evaluation of a biopsy. Clinical and radiological features are also important in aiding diagnosis and to complete the staging of bone cancer. In addition to these, there are several non-specific serological or specific molecular markers for bone neoplasms. In bone tumors, molecular markers increase the accuracy of the diagnosis and assist in subtyping bone tumors. Here, we review these markers and discuss their role in the diagnosis and prognosis of the three most frequent malignant bone neoplasms, namely osteosarcoma, chondrosarcoma, and Ewing sarcoma.

The management of Ewing's sarcoma family of tumors (ESFT, Ewing's sarcoma/primitive neuroectodermal tumor) has been established as a multimodality treatment. Advances in imaging and diagnostics, chemotherapy, surgical techniques, radiotherapy and prosthetic technology have resulted in drastic changes in the outcome of this disease, with most of the recent studies having 5-year survival rates of more than 60%. The Indian patients present at a more advanced stage and the compliance of treatment is suboptimal. While there is plenty of data in the world literature on the outcome of Ewing's sarcoma, there is paucity of data in Indian patients. Therefore, we conducted the present study to analyze the outcome of multimodality treatment of ESFT of the extremities at a tertiary nonprofit institute over a decade. 34 patients who had histopathologically proven diagnosis of Ewing's sarcoma of the extremities and had received treatment at our institute from 1997 through 2007 were included for analysis. The majority of patients had involvement of the femur (35%), followed by tibia (17%), fibula and foot (15% each), humerus (12%) and soft tissue of thigh (6%). Twenty-nine patients presented with localized disease (Enneking stage II B) while five patients presented with metastases (Enneking stage III). All patients received Vincristine, Actinomycin D, Cyclofosfamide + Ifosfamide and Etoposide (VAC+IE)-based chemotherapy and local treatment was offered to all but three patients having multicentric disease. The local treatment offered were, radiation (n= 15), surgery (n= 12) both surgery and radiation (n=4). All patients were analyzed for oncological outcome (event-free and overall survival, local and systemic relapses) by clinical and imaging evaluation and functional outcome by using the musculoskeletal tumor society (MSTS) score. These outcomes were correlated with age, sex, size of tumor, stage at presentation, modality of local treatment and site of relapse. At the final follow-up (mean, 26 months; median, 17 months; range, 3-97 months), the overall and event-free survivals were 47 ± 12% and 34 ± 9%, respectively. Sixty-two percent of the patients presented with a tumor size more than 8 cm. On correlation with age, sex, size of tumor, stage at presentation, modality of local treatment and site of relapse, no correlation of survival was seen with any of the variables except event-free survival with size of the tumor. The functional outcome of all the patients was satisfactory (MSTS score >16 out of 30). No patient underwent amputation. Although the demographic profile, stage at presentation and the local and systemic treatment regimen followed in our study was similar to the world literature, the outcome of Ewing's sarcoma in Indian patients were found to be inferior to that reported in the western literature. Larger multicentric studies with longer follow-up are required to exactly determine the key areas crucial in improving this outcome.

Neonatal treatment of hamsters with diethylstilbestrol (DES) induces uterine hyperplasia/dysplasia/neoplasia (endometrial adenocarcinoma) in adult animals. We subsequently determined that the neonatal DES exposure event directly and permanently disrupts the developing hamster uterus (initiation stage) so that it responds abnormally when it is stimulated with estrogen in adulthood (promotion stage). To identify candidate molecular elements involved in progression of the disruption/neoplastic process, we performed: 1) immunoblot analyses and 2) microarray profiling (Affymetrix Gene Chip System) on sets of uterine protein and RNA extracts, respectively, and 3) immunohistochemical analysis on uterine sections; all from both initiation stage and promotion stage groups of animals. Here we report that: 1) progression of the neonatal DES-induced hyperplasia/dysplasia/neoplasia phenomenon in the hamster uterus involves a wide spectrum of specific gene expression alterations and 2) the gene products involved and their manner of altered expression differ dramatically during the initiation vs. promotion stages of the phenomenon. Particularly interesting changes included members in the functional categories of nuclear receptors (progesterone receptor), cell-cell interactions (E-cadherin, connexins), cytokine action (IRF-1, Stat5A), growth factor action (IRS-1), extracellular matrix component (tenascin-C), transcription factors (Nrf2, Sp1), and multi-functional nuclear protein (SAFB1).

Figitumumab is a fully human IgG2 monoclonal antibody targeting the insulin-like growth-factor-1 receptor (IGF-1R). Preclinical data suggest a dependence on insulin-like growth-factor signalling for sarcoma subtypes, including Ewing's sarcoma, and early reports show antitumour activity of IGF-1R-targeting drugs in these diseases. Between January, 2006, and August, 2008, patients with refractory, advanced sarcomas received figitumumab (20 mg/kg) in two single-stage expansion cohorts within a solid-tumour phase 1 trial. The first cohort (n=15) included patients with multiple sarcoma subtypes, age 18 years or older, and the second cohort (n=14) consisted of patients with refractory Ewing's sarcoma, age 9 years or older. The primary endpoint was to assess the safety and tolerability of figitumumab. Secondary endpoints included pharmacokinetic profiling and preliminary antitumour activity (best response by Response Evaluation Criteria in Solid Tumours [RECIST]) in evaluable patients who received at least one dose of medication. This study is registered with ClinicalTrials.gov, number NCT00474760. 29 patients, 16 of whom had Ewing's sarcoma, were enrolled and received a total of 177 cycles of treatment (median 2, mean 6.1, range 1-24). Grade 3 deep venous thrombosis, grade 3 back pain, and grade 3 vomiting were each noted once in individual patients; one patient had grade 3 increases in aspartate aminotransferase and gammaglutamyltransferase concentrations. This patient also had grade 4 increases in alanine aminotransferase concentrations. The only other grade 4 adverse event was raised concentrations of uric acid, noted in one patient. Pharmacokinetics were comparable between patients with sarcoma and those with other solid tumours. 28 patients were assessed for response; two patients, both with Ewing's sarcoma, had objective responses (one complete response and one partial response) and eight patients had disease stabilisation (six with Ewing's sarcoma, one with synovial sarcoma, and one with fibrosarcoma) lasting 4 months or longer. Figitumumab is well tolerated and has antitumour activity in Ewing's sarcoma, warranting further investigation in this disease. Pfizer Global Research and Development. Copyright 2010 Elsevier Ltd.

2013-04-01

A rare case of a mixed endometrial stromal and smooth muscle tumor arising in the uterus of a 74-year-old woman is reported. The patient underwent hysterectomy for an enlarging uterine mass, and a large intramural tumor, showing marked central hyaline necrosis with calcification, was found. The tumor consisted of an admixture of a low-grade endometrial stromal sarcoma (ESS) and a fascicular proliferation of spindle cells suggesting smooth muscle differentiation, and a characteristic 'star-burst' appearance was found. In the ESS region, there were a few small foci of anaplasia where large polygonal cells with atypical nuclei and abundant eosinophilic cytoplasm proliferated, and the proliferative activity was locally increased in these foci. A small metastatic nodule appeared in the lung nine months after the hysterectomy, and the resected metastatic lesion showed features of anaplastic spindle cell sarcoma which was immunoreactive for CD10 but not for smooth muscle markers. Mixed endometrial stromal and smooth muscle tumors should be regarded as malignant neoplasms with the potential for hematogenous metastasis, particularly when they contain foci of cellular anaplasia. © 2013 The Authors.

Radiation-induced sarcoma is a rare complication of radiation therapy. We report a case of radiation-induced chondrosarcoma of the maxilla. An 80-year-old Persian woman developed radiation-induced chondrosarcoma of the left maxilla 7 years after combined chemotherapy and external beam radiation therapy for the Ann Arbor stage IE malignant lymphoma of the right tonsil. She underwent suboptimal tumour resection and died due to extensive locoregional disease 8 months later. An English language literature search of Medline using the terms chondrosarcoma, radiation-induced sarcoma and maxilla revealed only one earlier reported case. We describe the clinical and pathological features of this case and review the literature on radiation-induced sarcomas.

Many studies have described the diversity of synovial sarcoma in terms of its biological characteristics and clinical features. Moreover, much effort has been expended on the identification of prognostic factors because of unpredictable behaviors of synovial sarcomas. However, with the exception of tumor size, published results have been inconsistent. We attempted to identify independent risk factors using survival analysis. Forty-one consecutive patients with synovial sarcoma were prospectively followed from January 1997 to March 2008. Overall and progression-free survival for age, sex, tumor size, tumor location, metastasis at presentation, histologic subtype, chemotherapy, radiation therapy, and resection margin were analyzed, and standard multivariate Cox proportional hazard regression analysis was used to evaluate potential prognostic factors. Tumor size (>5 cm), nonlimb-based tumors, metastasis at presentation, and a monophasic subtype were associated with poorer overall survival. Multivariate analysis showed metastasis at presentation and monophasic tumor subtype affected overall survival. For the progression-free survival, monophasic subtype was found to be only 1 prognostic factor. The study confirmed that histologic subtype is the single most important independent prognostic factors of synovial sarcoma regardless of tumor stage.

Contribution to reconstruction of third degree rectovestibular lacerations in mares

The study was conducted on ten mares suffering from third degree rectovestibular laceration. Four uterine washes were performed in all cases by using diluted betadine (mixing 5ml of betadine antiseptic solution in 1 liter of sterile saline) to control vaginal and uterine infections before surgery. Surgical repair of third degree rectovestibular laceration was done by one-stage Goetz technique after four to six weeks of initial injury, with the lateral dissection continued extensively until the two flaps were created and brought to the midline without any tension. Primary healing occurred in all cases without significant complications. The obtained results indicate that mares with third degree rectovestibular lacerations are candidates for uterine wash and one-stage Goetz technique with excessive lateral continuation of the flap.

Endometrial cancer is the most common gynecologic malignancy in the developed countries. Clinical studies have shown that early stage uterine serous carcinoma (USC) has outcomes similar to early stage high grade endometrioid adenocarcinoma (EAC-G3) than to early stage low grade endometrioid adenocarcinoma (EAC-G1). However, little is known about the origin of these different clinical outcomes. This study applied the whole genome expression profiling to explore the expression difference of stage I USC (n = 11) relative to stage I EAC-G3 (n = 11) and stage I EAC-G1 (n = 11), respectively. We found that the expression difference between USC and EAC-G3, as measured by the number of differentially expressed genes (DEGs), is consistently less than that found between USC and EAC-G1. Pathway enrichment analyses suggested that DEGs specific to USC vs. EAC-G3 are enriched for genes involved in signaling transduction, while DEGs specific to USC vs. EAC-G1 are enriched for genes involved in cell cycle. Gene expression differences for selected DEGs are confirmed by quantitative RT-PCR with a high validation rate. This data, although preliminary, indicates that stage I USC is genetically similar to stage I EAC-G3 compared to stage I EAC-G1. DEGs identified from this study might provide an insight in to the potential mechanisms that influence the clinical outcome differences between endometrial cancer subtypes. They might also have potential prognostic and therapeutic impacts on patients diagnosed with uterine cancer.

Sarcomas differ from carcinomas in their mesenchymal origin. Therapeutic advancements have come slowly so alternative drugs and models are urgently needed. These studies report a new drug for sarcomas that simultaneously targets both tumor and tumor neovasculature. eBAT is a bispecific angiotoxin consisting of truncated, deimmunized Pseudomonas exotoxin fused to epidermal growth factor (EGF) and the amino terminal fragment (ATF) of urokinase. Here, we study the drug in an in vivo “ontarget” companion dog trial since eBAT effectively kills canine hemangiosarcoma (HSA) and human sarcoma cells in vitro. We reasoned the model has value due to the common occurrence of spontaneous sarcomas in dogs and a limited lifespan allowing for rapid accrual and data collection. Splenectomized dogs with minimal residual disease were given one cycle of eBAT followed by adjuvant doxorubicin in an adaptive dose-finding, phase I–II study of 23 dogs with spontaneous, stage I–II, splenic HSA. eBAT improved 6-month survival from <40% in a comparison population to ~70% in dogs treated at a biologically active dose (50 μg/kg). Six dogs were long-term survivors, living >450 days. eBAT abated expected toxicity associated with EGFR-targeting, a finding supported by mouse studies. Urokinase plasminogen activator receptor (uPAR) and EGFR are targets for human sarcomas, so thorough evaluation is crucial for validation of the dog model. Thus, we validated these markers for human sarcoma targeting in the study of 212 human and 97 canine sarcoma samples. Our results support further translation of eBAT for human patients with sarcomas and perhaps other EGFR-expressing malignancies. PMID:28193671

Implantation of the embryo into the uterus triggers the initiation of hemochorial placentation. The hemochorial placenta facilitates the acquisition of maternal resources required for embryo/fetal growth. Uterine spiral arteries form the nutrient supply line for the placenta and fetus. This vascular conduit undergoes gestation stage-specific remodeling directed by maternal natural killer cells and embryo-derived invasive trophoblast lineages. The placentation site, including remodeling of the uterine spiral arteries, is shaped by environmental challenges. In this review, we discuss the cellular participants controlling pregnancy-dependent uterine spiral artery remodeling and mechanisms responsible for their development and function. PMID:25023691

First results of endoscopic applications of optical coherence tomography (OCT) in gynecology are presented. We have studied mucosa of uterus, uterine cervix and vagina in vivo. Images of healthy endometrium in different stages of menstrual cycle have been recorded. For uterine cervix not only OCT data of normal state but some kids of pathology have been analyzed. Capability of OCT to identify alterations of mucosa makes this method promising for early diagnosis of tumors and precise guiding of excisional biopsy.

Factors affecting the feasibility of bilateral salpingo-oophorectomy during vaginal hysterectomy for uterine prolapse.

About 15% of all hysterectomies are performed for pelvic organ prolapse, generally through the transvaginal approach. However, concomitant bilateral salpingo-oophorectomy (BSO) is not always feasible through this approach, because the adnexae are sometimes inaccessible. To identify factors affecting the feasibility of performing BSO during transvaginal hysterectomy for uterine prolapse. We reviewed charts of all women undergoing vaginal hysterectomy for uterine prolapse in our institution between December 2005 and November 2009, at which time BSO was uniformly attempted in all patients. One hundred and seventy-two women who underwent vaginal hysterectomy were identified, of whom 134 (78%) underwent concomitant BSO. Women in whom BSO was feasible were younger (60.6±10.1 vs 65.6±8.6 years, P<0.02) and had a higher prevalence of advanced prolapse, including stage IV cystocele (68% vs 38%, P=0.01), stage III-IV rectocele (40% vs 11%, P=0.003) and stage IV uterine prolapse (64% vs 25%, P=0.0005). The feasibility of BSO was primarily dependent on the stage of pelvic organ prolapse and patients' age. Relaxation of the adnexae because of weakness of the infundibulo-pelvic ligaments may accompany severe pelvic organ prolapse and may potentially explain the feasibility of BSO in these women. © 2011 The Authors.

Perivascular epithelioid cell tumor (PEComa) is a rare subtype of mesenchymal origin tumor composed of epithelioid cells which exhibits immunohistochemical co-expressions of melanocytic markers and smooth muscle markers. In the first case, malignant uterine PEComa with vaginal and multiple lung metastasis was misdiagnosed preoperatively as uterine leiomyosarcoma despite a preoperative punch biopsy and immunohistochemical analysis of the metastatic vaginal mass. In the second case, synchronous uterine PEComa showing benign histology with lymph node involvement was incidentally detected after a staging operation for ovarian cancer. Definitive diagnosis of uterine PEComa was achieved only after hysterectomy despite preoperative assessment with pelvic magnetic resonance imaging and punch biopsy of metastatic lesion. The authors report two rare cases of uterine PEComa diagnosed postoperatively based on the morphologic and immunohistochemical features.

To determine MR imaging features and staging accuracy of neuroendocrine carcinomas (NECs) of the uterine cervix with pathological correlations. Twenty-six patients with histologically proven NECs, 60 patients with squamous cell carcinomas (SCCs), and 30 patients with adenocarcinomas of the uterine cervix were included. The clinical data, pathological findings, and MRI findings were reviewed retrospectively. MRI features of cervical NECs, SCCs, and adenocarcinomas were compared, and MRI staging of cervical NECs was compared with the pathological staging. Cervical NECs showed a higher tendency toward a homogeneous signal intensity on T2-weighted imaging and a homogeneous enhancement pattern, as well as a lower ADC value of tumour and a higher incidence of lymphadenopathy, compared with SCCs and adenocarcinomas (P < 0.05). An ADC value cutoff of 0.90 × 10 -3  mm 2 /s was robust for differentiation between cervical NECs and other cervical cancers, with a sensitivity of 63.3 % and a specificity of 95 %. In 21 patients who underwent radical hysterectomy and lymphadenectomy, the overall accuracy of tumour staging by MR imaging was 85.7 % with reference to pathology staging. Homogeneous lesion texture and low ADC value are likely suggestive features of cervical NECs and MR imaging is reliable for the staging of cervical NECs. • Cervical NECs show a tendency of lesion homogeneity and lymphadenopathy • Low ADC values are found in cervical NECs • MRI is an accurate imaging modality for the cervical NEC staging.

The sine oculis homeobox 1 (SIX1) is a member of the Six gene family. SIX1 is involved in tissue development by regulating proliferation, apoptosis, and differentiation. However, function of SIX1 in the uterus remains unknown. Here, we found that Six1 expression is regulated along the estrous cycle in mouse uterus. Six1 expression was significantly increased at estrus stage and decreased at the rest of stages. SIX1 is detected in the luminal and glandular epithelium of uterine endometrium at the estrus stage. Estrogen injection increased Six1 expression in the ovariectomized mouse uterus, whereas progesterone had no effect on its expression. Estrogenmore » receptor antagonist inhibited estrogen-induced Six1 expression. Our findings imply that SIX1 may play a role as an important regulator to orchestrate the dynamic of uterine endometrium in response to estrogen level during the estrous cycle. These results will give us a better understanding of uterine biology. - Highlights: • Six1 expression is regulated during the estrous cycle in mouse uterus. • Six1 is highly expressed at the estrus stage of estrous cycle. • SIX1 is detected in luminal/glandular epithelium of the uterus at the estrus stage. • Estrogen stimulates Six1 expression in an estrogen receptor-dependent manner.« less

OBJECTIVE To develop and use a biomechanical computer model to simulate the effect of varying the timing of voluntary maternal pushes during uterine contraction on second-stage labor duration. METHODS Published initial pelvic floor geometry was imported into technical computing software to build a simplified 3-D biomechanical model with six representative viscoelastic levator muscle bands interconnected by a hyperelastic iliococcygeal raphé. An incompressible sphere simulated the molded fetal head. Forces from uterine contraction and voluntary expulsive efforts were summed to push the model fetal head along the Curve of Carus opposed by the resistance of the pelvic floor structures to stretch. Holding uterine maximal contraction force and push strength constant, pushes were timed before (“Pre”), at (“Peak”), and after (“Post”) maximal uterine contraction force. The effect of different combinations of pushes on second stage duration and the number of pushes required for delivery were evaluated. RESULTS Calculated second stage durations ranged from 57.5 minutes (“triple” or Pre-Peak-Post pattern) to 75.8 minutes (“pre-push” and “post-push” patterns). Delivery with the “triple push” pattern required 59 voluntary pushes, while the “peak push” pattern required 23 voluntary pushes, a 61% reduction. The corresponding reduction for the “pre-and-peak push” pattern was 29%, the “peak-and-post push” pattern was 30%, the “pre-push” pattern was 54%, and the “post-push” pattern was 56%. CONCLUSION Although the “triple push” pattern resulted in a 16% shorter second stage, this came at the energetic expense of a 61% increase in the number of pushes required. PMID:19305333

We sought to review the current evidence in order to test the efficacy of adjuvant chemotherapy in improving disease-free survival in patients affected by early stage uterine leiomyosarcoma. On July 2016, literature was searched in order to identify trials comparing different postoperative adjuvant strategies for patients diagnosed with early stage uterine leiomyosarcoma. Our analysis included 360 patients: 145 (40%), 53 (15%), and 155 (43%) had chemotherapy (with or without radiotherapy), radiotherapy, and observation, respectively. Seven (2%) patients who had radiotherapy with or without chemotherapy were excluded from further analysis in order to reduce risk of biases. Administration of chemotherapy (with or without radiotherapy) did not improve outcomes in comparison to observation (OR: 0.79 (95%CI: 0.48, 1.29)), or radiotherapy (OR: 0.90 (95%CI: 0.42, 1.94)). Loco-regional recurrence rate was similar comparing patients undergoing chemotherapy (with or without radiotherapy) with having observation alone (OR: 0.84 (95%CI: 0.44, 1.60)). Similarly, pooled results suggested that chemotherapy administration did not affect distant recurrence rate in comparison to no chemotherapy (OR: 0.80 (95%CI: 0.50, 1.28)), and observation alone (OR: 0.99 (95%CI: 0.60, 1.64)). However, patients undergoing chemotherapy (with or without radiotherapy) experienced a trend towards lower risk of developing distant recurrences (OR: 0.49 (95%CI: 0.24, 1.03)) and a higher risk of developing loco-regional recurrences (OR: 3.45 (95%CI: 1.02, 11.73)) than patients undergoing radiotherapy. In early stage uterine leiomyosarcoma, the role of adjuvant chemotherapy remains unclear. Owing to the high recurrence rate, even in the early stage of disease, further innovative therapeutic strategies have to be tested. Copyright © 2016 Elsevier Inc. All rights reserved.

MR imaging findings of adenomyosis: correlation with histopathologic features and diagnostic pitfalls.

Adenomyosis is a nonneoplastic condition, characterized by benign invasion of ectopic endometrium into the myometrium with hyperplasia of adjacent smooth muscle. The common symptoms include dysmenorrhea, menorrhagia, and abnormal uterine bleeding, but these do not allow diagnosis. Therefore, imaging plays an important role because establishment of the correct preoperative diagnosis is critical to avoid unnecessary intervention. Magnetic resonance (MR) imaging is a highly accurate noninvasive modality for diagnosis of adenomyosis, differentiation of adenomyosis from other gynecologic disorders, and planning of appropriate treatment. Although the typical MR imaging findings are well established, adenomyosis actually varies widely in terms of histopathologic features (adenomyosis with sparse glands), growth patterns (polypoid adenomyoma, adenomyotic cyst, and miniature uterus), responses to hormonal activity (tamoxifen, decidual changes), and responses to treatment (gonadotropin-releasing hormone agonist). The MR imaging findings of adenomyosis occasionally mimic those of uterine malignancy or ovarian cancer. Furthermore, malignancy occasionally develops in otherwise benign adenomyosis. Pitfalls in diagnosis of adenomyosis include myometrial contractions, leiomyoma, adenomatoid tumor, metastases, endometrial carcinoma, and endometrial stromal sarcoma. Knowledge of the various appearances of adenomyosis and the possible pitfalls in differential diagnosis help guide the determination of appropriate treatment options. (c) RSNA, 2005.

Management of metastatic retroperitoneal sarcoma: a consensus approach from the Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG).

PubMed

2018-04-01

Retroperitoneal sarcoma (RPS) is a rare disease accounting for 0.1%-0.2% of all malignancies. Management of RPS is complex and requires multidisciplinary, tailored treatment strategies at all stages, but especially in the context of metastatic or multifocal recurrent disease. Due to the rarity and heterogeneity of this family of diseases, the literature to guide management is limited. The Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG) is an international collaboration of sarcoma experts from all disciplines convened in an effort to overcome these limitations. The TARPSWG has compiled the available evidence surrounding metastatic and multifocally recurrent RPS along with expert opinion in an iterative process to generate a consensus document regarding the complex management of this disease. The objective of this document is to guide sarcoma specialists from all disciplines in the diagnosis and treatment of multifocal recurrent or metastatic RPS. All aspects of patient assessment, diagnostic processes, local and systemic treatments, and palliation are reviewed in this document, and consensus recommendations provided accordingly. Recommendations were guided by available evidence, in conjunction with expert opinion where evidence was lacking. This consensus document combines the available literature regarding the management of multifocally recurrent or metastastic RPS with the practical expertise of high-volume sarcoma centers from multiple countries. It is designed as a tool for decision making in the complex multidisciplinary management of this condition and is expected to standardize management across centers, thereby ensuring that patients receive the highest quality care.

Placentation in the eastern water skink (Eulamprus quoyii): a placentome-like structure in a lecithotrophic lizard

The eastern water skink (Eulamprus quoyii) has lecithotrophic embryos and was previously described as having a simple Type I chorioallantoic placenta. Indeed, it was the species upon which the definition of a Type I placenta was thought to be based, although we had cause to question that assumption. Hence we have described the morphology of the uterus of E. quoyii and found it to be more complex than previously supposed. The mesometrial pole of the uterus in E. quoyii displays a vessel-dense elliptical structure (the VDE) with columnar uterine epithelial cells. As pregnancy proceeds, the uterine epithelium near the mesometrial pole becomes folded and glands become hypertrophied, so that the morphology of VDE resembles that of a placentome, characteristic of Type III placentae. Unlike species with a Type III placenta, the apposing chorioallantoic membrane of E. quoyii is lined with squamous cells and interdigitates with the folded uterine epithelium. The remainder of the uterus is thin with a squamous uterine epithelium throughout pregnancy. Immunohistochemical localisation of blood vessels reveals a dense network of small capillaries directly beneath the folded epithelium of the VDE, while blood vessels are larger and sparser at the abembryonic pole of the uterus. Alkaline phosphatase (AP) activity is present in the uterine epithelium and sub-epithelial blood vessels in newly ovulated females. AP activity disappears from the epithelium between stages 27 and 29 of embryonic development and from the blood vessels after stage 34, but appears in the uterine glands at stage 35, where it remains until the end of pregnancy. Although the VDE is structurally similar to the placentomes found in other viviparous lizards, different distributions of AP activity in the uterus of E. quoyii and Pseudemoia spenceri suggest that the VDE may be functionally different from the placentome of the latter species. Our description of uterine morphology in E. quoyii provides evidence that, at least in some lineages, the evolution of a placentome may not occur in concert with the evolution of microlecithal eggs and obligate placentotrophy.

Nitric oxide (NO) may have a role in persistent breeding-induced endometritis in mares through an inhibitory effect on uterine contractility. The objectives of this study were to test the effect of NO on spontaneous uterine contractility in-vitro and to evaluate whether this effect varied between the longitudinal and circular muscle layers of the uterus. Reproductive tracts were collected from eight euthanized non-pregnant mares (age 4-19 years; body weight 405-530 kg). Transrectal examination of the reproductive tract was performed before euthanasia to evaluate stage of the estrous cycle and presence of any apparent abnormality. After euthanasia, one uterine tissue sample was collected for histological evaluation and four full-thickness uterine tissue strips (10-12 mm × 2 mm), two parallel to each muscle layer, were excised for in-vitro contractility evaluation. Strips were suspended in tissue chambers containing Krebs-Henseleit solution, with continuous aeration (95% O 2 -5% CO 2 ; pH 7.4) at 37 °C. After equilibration, spontaneous contractility was recorded (pre-treatment) and strips excised in each direction were randomly allocated to each of two groups: 1) SNAP (S-nitroso-N-acetylpenicillamine, an NO donor); or 2) NAP (N-acetyl-d-penicillamine, vehicle and time-matched control). These were treated at 15 min intervals with increasing concentrations (10 -7  M to 10 -3  M) of SNAP and NAP, respectively. Contractility data was recorded throughout the experiment. An interaction effect of group-by-concentration was observed (P < 0.0001). The mean contractility after treatment with 10 -4  M and 10 -3  M SNAP were significantly lower than the pre-treatment contractility and the mean contractility after treatment with lower SNAP concentrations. In contrast, contractility did not change significantly in the NAP treated controls. The effect of treatment on uterine contractility was not influenced by age or weight of the mare, stage of estrous cycle, uterine histology grade, or muscle layer. Secondary findings included significant main effects of stage of estrous cycle (increased contractility in estrus compared to diestrus), uterine histology grade (decreased contractility in grade IIB compared to grade I) and age (decreased contractility in mares aged > 8 years compared to mares aged ≤ 8 years). In conclusion, results of this study indicate that NO has a dose-dependent inhibitory effect on spontaneous uterine contractility irrespective of the muscle layer in the mare.

Background Endometrial cancer is the most common gynecologic malignancy in the developed countries. Clinical studies have shown that early stage uterine serous carcinoma (USC) has outcomes similar to early stage high grade endometrioid adenocarcinoma (EAC-G3) than to early stage low grade endometrioid adenocarcinoma (EAC-G1). However, little is known about the origin of these different clinical outcomes. This study applied the whole genome expression profiling to explore the expression difference of stage I USC (n = 11) relative to stage I EAC-G3 (n = 11) and stage I EAC-G1 (n = 11), respectively. Methodology/Principal Finding We found that the expression difference between USC and EAC-G3, as measured by the number of differentially expressed genes (DEGs), is consistently less than that found between USC and EAC-G1. Pathway enrichment analyses suggested that DEGs specific to USC vs. EAC-G3 are enriched for genes involved in signaling transduction, while DEGs specific to USC vs. EAC-G1 are enriched for genes involved in cell cycle. Gene expression differences for selected DEGs are confirmed by quantitative RT-PCR with a high validation rate. Conclusion This data, although preliminary, indicates that stage I USC is genetically similar to stage I EAC-G3 compared to stage I EAC-G1. DEGs identified from this study might provide an insight in to the potential mechanisms that influence the clinical outcome differences between endometrial cancer subtypes. They might also have potential prognostic and therapeutic impacts on patients diagnosed with uterine cancer. PMID:21448288

This is the first study carried out to describe the role of fetal microchimerism (FM) in the pathogenesis of uterine cancer. The prevalence and concentration of male fetal microchimeric cells (FMCs) were examined in endometrial tissues in relation to subtypes of uterine cancer, and the histological grade and stage of the tumor. FM occurrence was analyzed in relation to risk factors, including hypertension, obesity, type 2 diabetes, dyslipidemia, age at cancer diagnosis, and patient pregnancy history. The prevalence and concentration of FMCs were examined in endometrial tissues using real-time polymerase chain reaction, SRY and β-globin sequences as markers for male fetal FMCs and total DNA. The studied group involved 47 type 1 endometrial cancers, 28 type 2 endometrial cancers, and 41 benign uterine diseases. While the prevalence of FM was decreased only in type 1 endometrial cancer, compared with benign uterine disorders (38.3% vs.70.7%; odds ratio [OR]=0.257, 95% confidence interval [CI]: 0.105 to 0.628, p=0.003), FMC concentrations did not differ within examined groups. The lower FM prevalence was detected in low-grade (grade 1 and grade 2) endometrioid cancer (38.3% vs. 70.7%, OR=0.256, 95% CI: 0.105 to 0.627, p=0.003) and in FIGO 1 tumors (40.7% vs. 70.7%, OR=0.285, 95% CI: 0.120 to 0.675, p=0.004). No correlation between FM prevalence or FMC concentrations and risk factors was demonstrated. A lower prevalence of male FM seemed to be associated with better prognoses in uterine cancer based on tumor subtype, histological grade, and stage of the tumor. PMID:24283364

To study sarcomagenesis of the mammary gland and estimate the degree of maturity of its various stages, the author examined 45 postoperative specimens of fibroadenomatosis, fibroadenoma, leaf-shape tumor, sarcoma from the preexisting leaf-shape tumor and stromal sarcoma. Studies on the nucleus-plasma relationship, the mitotic coefficient, frequency and pathology of mitosis and quantitative-qualitative changes in sex chromatin allowed a more reliable estimation of the degree of maturity of cell elements of the fibroblastic origin in the process of malignant transformation.

Despite multimodal treatment, long term outcome for patients with Ewing sarcoma is still poor. The second “European interdisciplinary Ewing sarcoma research summit” assembled a large group of scientific experts in the field to discuss their latest unpublished findings on the way to the identification of novel therapeutic targets and strategies. Ewing sarcoma is characterized by a quiet genome with presence of an EWSR1-ETS gene rearrangement as the only and defining genetic aberration. RNA-sequencing of recently described Ewing-like sarcomas with variant translocations identified them as biologically distinct diseases. Various presentations adressed mechanisms of EWS-ETS fusion protein activities with a focus on EWS-FLI1. Data were presented shedding light on the molecular underpinnings of genetic permissiveness to this disease uncovering interaction of EWS-FLI1 with recently discovered susceptibility loci. Epigenetic context as a consequence of the interaction between the oncoprotein, cell type, developmental stage, and tissue microenvironment emerged as dominant theme in the discussion of the molecular pathogenesis and inter- and intra-tumor heterogeneity of Ewing sarcoma, and the difficulty to generate animal models faithfully recapitulating the human disease. The problem of preclinical development of biologically targeted therapeutics was discussed and promising perspectives were offered from the study of novel in vitro models. Finally, it was concluded that in order to facilitate rapid pre-clinical and clinical development of novel therapies in Ewing sarcoma, the community needs a platform to maintain knowledge of unpublished results, systems and models used in drug testing and to continue the open dialogue initiated at the first two Ewing sarcoma summits.

Hypoxia is a critical factor in the progression and metastasis of many cancers, including soft tissue sarcomas. Frequently, oxygen (O2) gradients develop in tumors as they grow beyond their vascular supply, leading to heterogeneous areas of O2 depletion. Here, we report the impact of hypoxic O2 gradients on sarcoma cell invasion and migration. O2 gradient measurements showed that large sarcoma mouse tumors (>300 mm3) contain a severely hypoxic core [≤0.1% partial pressure of O2 (pO2)] whereas smaller tumors possessed hypoxic gradients throughout the tumor mass (0.1–6% pO2). To analyze tumor invasion, we used O2-controllable hydrogels to recreate the physiopathological O2 levels in vitro. Small tumor grafts encapsulated in the hydrogels revealed increased invasion that was both faster and extended over a longer distance in the hypoxic hydrogels compared with nonhypoxic hydrogels. To model the effect of the O2 gradient accurately, we examined individual sarcoma cells embedded in the O2-controllable hydrogel. We observed that hypoxic gradients guide sarcoma cell motility and matrix remodeling through hypoxia-inducible factor-1α (HIF-1α) activation. We further found that in the hypoxic gradient, individual cells migrate more quickly, across longer distances, and in the direction of increasing O2 tension. Treatment with minoxidil, an inhibitor of hypoxia-induced sarcoma metastasis, abrogated cell migration and matrix remodeling in the hypoxic gradient. Overall, we show that O2 acts as a 3D physicotactic agent during sarcoma tumor invasion and propose the O2-controllable hydrogels as a predictive system to study early stages of the metastatic process and therapeutic targets.

Ewing's sarcoma uncommonly arises from extraosseous soft tissue or parenchymal organs. Primary adrenal Ewing's Sarcoma, although very rare, is extremely aggressive and commonly fatal. A 17 year old Pakistani male was referred to the outpatient oncology clinic at our center with a three month history of concomitant pain, swelling and dragging sensation in the right hypochondrium. Abdominal examination revealed a large, firm mass in the right hypochondrium extending into the right lumbar region and epigastrium. His genital exam was unremarkable and there were no stigmata of hepatic or adrenal disease.Computed tomography scans revealed a large peripherally enhancing mass in the hepatorenal area, biopsy of which showed a neoplastic lesion composed of small round blue cells which exhibited abundance of glycogen and stained diffusely positive for CD99 (MIC2 antigen). Fluorescence in situ hybridization demonstrated gene rearrangement at chromosome 22q12 which confirmed the diagnosis of Ewing's sarcoma. Staging scans revealed pulmonary metastasis and hence he was commenced on systemic chemotherapy. This case report highlights the importance of keeping Ewing's sarcoma in mind when a young patient presents with a large non-functional adrenal mass.

Retroviruses are valuable tools in studies of embryonic development, both as gene expression vectors and as cell lineage markers. In this study early chicken blastoderm cells are shown to be permissive for infection by Rous sarcoma virus and derivative replication-defective by Rous sarcoma virus and derivative replication-defective vectors, and, in contrast to previously published data, these cells will readily express viral genes. In cultured blastoderm cells, Rous sarcoma virus stably integrates and is transcribed efficiently, producing infectious virus particles. Using replication-defective vectors encoding the bacterial lacZ gene, the authors further show that blastoderms can be infected in culture and inmore » ovo. In ovo, lacZ expression is seen within 24 hours of virus inoculation, and by 96 hours stably expressing clones of cells are observed in diverse tissues throughout the embryo, including epidermis, somites, and heart, as well as in extraembryonic membranes. Given the rapid onset of vector expression and the broad range of permissive cell types, it should be feasible to use Rous sarcoma virus-derived retroviruses as early lineage markers and expression vectors beginning at the blastoderm stage of avian embryogenesis.« less

Purpose: Adjuvant radiation therapy (RT) in early-stage high- to intermediate-risk endometrioid adenocarcinoma is well established and has been shown to improve locoregional control. Its role in the management of early-stage clear cell carcinoma and uterine papillary serous carcinoma (UPSC) remains controversial. Methods and Materials: Using the Surveillance Epidemiology and End Results database, we identified women with American Joint Committee on Cancer Stage Sixth Edition. Stage IA-IIB clear cell carcinoma or UPSC who underwent hysterectomy with or without adjuvant RT between 1988 and 2003. We used Kaplan-Meier and Cox regression analysis to compare overall survival (OS) for all patients. Results: Wemore » identified 1,333 women of whom 451 had clear cell carcinoma and 882 had UPSC. Of those patients, 775 underwent surgery alone and 558 received adjuvant RT as well. For Stages I-IIB disease, the median OS with surgery alone was 106 months, vs. 151 months with adjuvant RT (p = 0.006). On subgroup analysis, we saw the benefit from adjuvant RT only in Stage IB-C patients. For Stage IB disease, patients undergoing surgery alone had a median OS of 117 months, vs. median survival not reached with the addition of RT (p = 0.006). For Stage IC disease, surgery alone had a median OS of 35 months vs. 120 months with RT (p = 0.001). Although the apparent benefit of RT diminished when measured via multivariate analysis, the impact of RT on survival did show a trend toward significance (hazard ration 0.808, confidence interval 95% 0.651-1.002, p = 0.052) Conclusion: In FIGO Stage IB-C papillary serous and clear cell uterine carcinoma, adjuvant RT seems to play an important role in improving survival.« less

To assess the incidence, predictors, and outcomes of Kaposi sarcoma-associated paradoxical immune reconstitution inflammatory syndrome (KS-IRIS) in antiretroviral therapy (ART)-naive HIV-infected patients with Kaposi sarcoma initiating ART in both well resourced and limited-resourced settings. Pooled analysis of three prospective cohorts of ART-naive HIV-infected patients with Kaposi sarcoma from sub-Saharan Africa (SSA) and one from the UK. KS-IRIS case definition was standardized across sites. Cox regression and Kaplan-Meier survival analysis were used to identify the incidence and predictors of KS-IRIS and Kaposi sarcoma-associated mortality. Fifty-eight of 417 (13.9%) eligible individuals experienced KS-IRIS with an incidence 2.5 times higher in the African vs. European cohorts (P=0.001). ART alone as initial Kaposi sarcoma treatment (hazard ratio 2.97, 95% confidence interval (CI) 1.02-8.69); T1 Kaposi sarcoma stage (hazard ratio 2.96, 95% CI 1.26-6.94); and plasma HIV-1 RNA more than 5 log₁₀ copies/ml (hazard ratio 2.14, 95% CI 1.25-3.67) independently predicted KS-IRIS at baseline. Detectable plasma Kaposi sarcoma-associated herpes virus (KSHV) DNA additionally predicted KS-IRIS among the 259 patients with KSHV DNA assessed (hazard ratio 2.98, 95% CI 1.23-7.19). Nineteen KS-IRIS patients died, all in SSA. Kaposi sarcoma mortality was 3.3-fold higher in Africa, and was predicted by KS-IRIS (hazard ratio 19.24, CI 7.62-48.58), lack of chemotherapy (hazard ratio 2.35, 95% CI 1.09-5.05), pre-ART CD4 cell count less than 200 cells/μl (hazard ratio 2.04, 95% CI 0.99-4.2), and detectable baseline KSHV DNA (hazard ratio 2.12, 95% CI 0.94-4.77). KS-IRIS incidence and mortality are higher in SSA than in the UK. This is largely explained by the more advanced Kaposi sarcoma disease and lower chemotherapy availability. KS-IRIS is a major contributor to Kaposi sarcoma-associated mortality in Africa. Our results support the need to increase awareness on KS-IRIS, encourage earlier presentation, referral and diagnosis of Kaposi sarcoma, and advocate on access to systemic chemotherapy in Africa. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Few cases of clostridial gas gangrene associated with uterine malignancy have been reported. We report on a 46-year-old woman with clostridial sepsis. On the day of admission due to severe abdominal pain, peritonitis was diagnosed, and computed tomography showed free air in the abdomen. At emergency laparotomy, perforation of the necrotic uterine wall was observed. During hysterectomy, septic shock developed, and life-saving therapy was performed in the intensive care unit after surgery. Pathological examination of the necrotic uterine wall showed grade III endometrial adenocarcinoma of the uterine endometrium (International Federation of Gynecology and Obstetrics stage IIIa) with gas gangrene due to Clostridium perfringens. This report aims to alert gynecologists to the possibility that clostridial gas gangrene of the uterus can occur in patients with peritonitis and intra-abdominal free air. Early recognition and aggressive therapy can save patients' lives.

Endometrial intraepithelial carcinoma (EIC) is a rare pathologic variant of uterine serous carcinoma (USC). Our aim is to distinguish patterns of clinic-pathologic outcomes in patients with EIC and USC for disease limited to the endometrium (stage 1A) as well as with distant metastasis (stage 4B). Surgically staged patients were retrospectively identified and relevant variables were extracted and compared. Kaplan-Meier was used to generate the survival data. More USC (n = 29) exhibited lymphovascular invasion (stage 4, P = .01) and expressed higher levels of estrogen receptor-α than EIC (P = .0009 and .063 for stages 1 and 4, respectively). The survival is comparable, with 1 recurrence in each group for stage 1A disease. For stage 4 EIC and USC, the progression-free survival (14 vs10 months) and overall survival (19 vs 20 months) are similar to what is previously published. In conclusion, EIC, whether limited to the endometrium, or widely metastatic, imparts similar outcomes and should be treated comparably with stage-matched USC.

Although the effectiveness of nuclear hormone-receptor complexes is known to depend on coregulator partner proteins, relatively little is known about the roles of coregulators in uterine development and early stages of pregnancy and implantation. Because conventional genetic deletion of the coregulator, repressor of estrogen receptor activity (REA), was embryonic lethal, we here study REA conditional knockout mice generated by cre-loxP recombination, in which REA function was abrogated only in progesterone receptor-expressing tissues, to define the roles of REA in postembryonic stages and in a tissue-specific manner. We find that REA has gene dose-dependent activity impacting uterine development and fertility. Conditional homozygous mutant (REAd/d) mice developed to adulthood and showed normal ovarian function, but females were infertile with severely compromised uterine development and function characterized by cell cycle arrest, apoptosis, and altered adenogenesis (endometrial gland morphogenesis), resulting in failure of implantation and decidualization. By contrast, mice heterozygous for REA (REAf/d) had a very different phenotype, with estradiol treatment resulting in hyperstimulated, large uteri showing increased proliferation of luminal epithelial cells, and enhanced fluid imbibition associated with altered regulation of aquaporins. These REAf/d female mice showed a subfertility phenotype with reduced numbers and sizes of litters. These findings highlight that uterine development and regulation of estrogen receptor activities show a bimodal dependence on the gene dosage of REA. Optimal uterine development and functional activities require the normal gene dosage of REA, with partial or complete deletion resulting in hyperresponsiveness or underresponsiveness to hormone and subfertility or infertility, respectively.

Background: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT. Aims: We aimed to define the prognostic and predictive factors associated with treatment options in ovarian (OCS) and uterine carcinosarcoma (UCS). Study Design: Retrospective cross-sectional study Methods: We retrospectively reviewed the medical records of patients with ovarian and uterine carcinosarcoma from 2000 to 2013, and 127 women were included in this study (24 ovarian and 103 uterine). Patients admitted to seventeen oncology centres in Turkey between 2000 and December 2013 with a histologically proven diagnosis of uterine carcinosarcoma with FIGO 2009 stage I–III and patients with sufficient data obtained from well-kept medical records were included in this study. Stage IV tumours were excluded. The patient records were retrospectively reviewed. Data from 104 patients were evaluated for this study. Results: Age (≥70 years) was a poor prognostic factor for UCS (p=0.036). Pelvic±para aortic lymph node dissection did not affect overall survival (OS) (p=0.35). Macroscopic residual disease was related with OS (p<0.01). The median OS was significantly longer in stage I–II patients than stage III patients (p=0.03). Adjuvant treatment improved OS (p=0.013). Adjuvant radiotherapy tended to increase the median OS (p=0.075). However, this tendency was observed in UCS (p=0.08) rather than OCS (p=0.6).Adjuvant chemotherapy had no effect on OS (p=0.15).Adjuvant radiotherapy significantly prolonged the median OS in patients with endometrioid component (p=0.034). A serous/clear cell component was a negative prognostic factor (p=0.035). Patients with serous/clear cell histology for whom adjuvant chemotherapy was applied had significantly longer OS (p=0.019), and there was no beneficial effect of adjuvant radiotherapy (p=0.4). Adjuvant chemotherapy was effective in heterologous tumours (p=0.026). In multivariate analysis, the stage and chemotherapy were prognostic factors for all patients. Age was an independent prognostic factor for UCS. However, serous/clear cell histology and radiotherapy tended to be significant prognostic factors. Conclusion: The primary location, the histological type of sarcomatous and the epithelial component may be predictive factors for the efficacy of chemotherapy or radiotherapy in UCS and OCS.

[Lymph drainage therapy in secondary lymphedema caused by Kaposi sarcoma].

Einfeldt, H

For reasons not yet known HIV infected patients in the final state of their aids disease often tend to develop Kaposi's sarcoma. These tumours result in secondary lymphatic edemas which are found on both sides of the sarcoma. They reach up to the regional lymphatic nodes blocked by the tumour cells. Depending on the state of the edema a lymphaticdrainage treatment is indicated palliatively; the patients can thus be relieved. A fundamental deterioration of prognosis is not to be expected, as all patients are anyway in the final stage of this not yet curable disease. Differing from treatment of other lymphatic edema, it is of special importance to the therapist - apart from the particular and difficult psychic burden - to pay attention to infection protection by using gloves for each single treatment.

To clarify the histopathological characteristics of rat endometrial stromal sarcoma (ESS), we morphologically reviewed 12 malignant uterine tumors protruding into the lumen in previous rat carcinogenicity studies. The 12 cases were classified into the following 6 types based on their morphological features: spindle cell and collagen rich type, pleomorphic/spindle cell and compact type, decidual alteration type, histiocytic and multinucleated giant cell mixture type, Antoni A-type schwannoma type, and Antoni B-type schwannoma type. Immunohistochemically, tumor cells in all cases exhibited focal or diffuse positive reactions for vimentin, and 11 of the 12 cases were positive for S-100. Interestingly, 9 cases were positive for desmin or αSMA, indicating tumor cells expressing smooth muscle properties. Both Antoni A- and B-type schwannoma types showed low reactions for both muscle markers. Positive results for estrogen receptor α in the 11 cases suggested that they were derived from endometrial stromal cells. On the basis of their immunohistochemical profiles, they were considered to be derived from endometrial stromal cells while they showed morphological variation. The detection of a basement membrane surrounding tumor cells might not be a definitive indicator for differential diagnosis of ESS from malignant schwannoma. In conclusion, ESS could exhibit wide morphological and immunohistochemical variation including features of schwannoma or smooth muscle tumor.

Cancer stem cells can play an important role in tumorigenesis and tumor progression. However, it is still difficult to detect and isolate cancer stem cells. An alternative approach is to analyse stem cell-associated gene expression. We investigated the coexpression of three stem cell-associated genes, Hiwi, hTERT and survivin, by quantitative real-time-PCR in 104 primary soft-tissue sarcomas (STS). Multivariate Cox's proportional hazards regression analyses allowed correlating gene expression with overall survival for STS patients. Coexpression of all three stem cell-associated genes resulted in a significantly increased risk of tumor-related death. Importantly, tumors of patients with the poorest prognosis were of all four tumor stages, suggesting that their risk is based upon coexpression of stem cell-associated genes rather than on tumor stage.

Prognostic significance of tumor histology and four computed tomography (CT) staging methods was tested retrospectively in dogs from three treatment centers that underwent intent-to-cure-radiotherapy for intranasal neoplasia. Disease-free and overall survival times were available for 94 dogs. A grouping of anaplastic, squamous cell, and undifferentiated carcinomas had a significantly shorter median disease-free survival (4.4 mo) than a grouping of all sarcomas (10.6 months). Disease-free survivals were not significantly different, when all carcinomas were compared with all sarcomas. The published original and modified WHO staging methods did not significantly relate to either survival endpoint. A modified human maxillary tumor staging system previously applied to canine nasal tumors was prognostically significant for both survival endpoints; a further modified version of that CT-based staging system resulted in improved significance for both survival endpoints. Dogs with unilateral intranasal involvement without bone destruction beyond the turbinates on CT, had longest median survival (23.4 months); CT evidence of cribriform plate involvement was associated with shortest median survival (6.7 months). Combining CT and histology statistically improved prognostic significance for both survival endpoints over the proposed CT staging method alone. Significance was lost when CT stages were collapsed to < four categories or histopathology groupings were collapsed to < three categories.

Fetal- and uterine-specific antigens in human amniotic fluid.

Removal of the major maternal serum proteins from second trimester amniotic fluid by antibody affinity chromatography revealed various soluble tissue antigens, of which two were fetal-specific skin proteins and another, of alpha2-mobility, was specific to the uterus, and was therefore designated alpha-uterine protein (AUP). These proteins could not be detected in maternal serum by antibody-antigen crossed electrophoresis. The concentration of AUP in amniotic fluid reached a maximum between 10 and 20 weeks of gestation, suggesting that there is an influx of uterine protein into the amniotic fluid at this stage of pregnancy.

Abstract Primary uterine non-Hodgkin's lymphoma is extremely rare accounting for <1% of all extranodal non-Hodgkin's lymphomas. Imaging findings of primary uterine lymphoma have rarely been reported before. We present magnetic resonance imaging (MRI) and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT findings in a patient with primary uterine peripheral T-cell lymphoma. A 27-year-old female presented with intermittent fever with neutropenia for 7 months. MRI showed an ill-defined mass involved both the uterine corpus and cervix, resulting in diffuse enlargement of the uterus. This mass showed inhomogeneous hypointensity on unenhanced T1-weighted images, hyperintensity on diffusion-weighted imaging, relative hypointensity compared to the surrounding myometrium on T2-weighted images and lower enhancement than the surrounding myometrium on enhanced T1-weighted images. FDG PET/CT showed intense FDG uptake in the thickened wall of the uterine corpus and cervix with SUVmax of 26.9. There were multiple hypermetabolic lymph nodes in the pelvis and retroperitoneum. Uterine curettage and CT-guided biopsy of the uterine mass revealed peripheral T-cell lymphoma. Bone marrow biopsy revealed no evidence of lymphomatous involvement. The imaging and pathologic findings were consistent with primary uterine lymphoma. After 3 circles of chemotherapy, follow-up enhanced MRI showed decreased thickness of the uterine wall. Despite its rarity, primary uterine non-Hodgkin's lymphoma should be taken into consideration when a uterine tumor shows large size, relative hypointesity on both T2-weighted images and enhanced T1-weighted images compared to the surrounding myometrium, and intense FDG uptake on PET/CT. MRI may be helpful for describing the relationship between the tumor and adjacent structures. FDG PET/CT may be useful for tumor detection and staging. PMID:27124063

There is little published information on effective treatment of Kaposi's sarcoma (KS) in children in low-income countries. We prospectively treated 12 patients with an institutional review board-approved protocol consisting of four monthly courses of doxorubicin (Adriamycin), bleomycin and vincristine sulphate (ABV), with highly active antiretroviral therapy (HAART) plus co-trimoxazole prophylaxis for those who were HIV-positive, with additional vincristine if remission was not achieved after 4 months. Maintenance HAART plus co-trimoxazole was given to all HIV-positive patients. A fine-needle aspirate and CD4+ count were done if possible, and staging was performed according to Mitsuyasu. Eight of ten HIV-positive patients with stage III - IVB disease, and both HIV-negative patients with stage I disease, were in remission after 473 - 1 490 (mean 939) days. One patient died after absconding during treatment, and one died from neutropenia-related pulmonary infection. ABV with or without HAART is an effective treatment option for children with KS.

Soft tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin that display a heterogenous mix of clinical and pathologic characteristics. STS can develop from fat, muscle, nerves, blood vessels, and other connective tissues. The evaluation and treatment of patients with STS requires a multidisciplinary team with demonstrated expertise in the management of these tumors. The complete NCCN Guidelines for Soft Tissue Sarcoma (available at NCCN.org) provide recommendations for the diagnosis, evaluation, and treatment of extremity/superficial trunk/head and neck STS, as well as intra-abdominal/retroperitoneal STS, gastrointestinal stromal tumor, desmoid tumors, and rhabdomyosarcoma. This manuscript discusses guiding principles for the diagnosis and staging of STS and evidence for treatment modalities that include surgery, radiation, chemoradiation, chemotherapy, and targeted therapy.

Malignant mixed Mullerian tumour is a rare gynaecological tumour commonly presenting with vaginal bleeding, abdominal pain or mass in the uterine cavity, cervix or vagina. The neoplasms are commonly seen in postmenopausal women although it has been observed in younger women. Ovaries and the corpus of the uterus are commonly involved, whereas involvement of the cervix and vagina is rare. A 37 year-old Tanzania lady para 7 with a previous history of two genital polypectomies presented with history of recurrent vaginal mass which was associated with abnormal vaginal bleeding and foul smelling discharge. Vaginal examination revealed a prolapsed uterus with giant fungating cervical mass which was ulcerated, friable, and bled easily on touch. Impression was grade three uterine prolapse with infected cervical polyp/cervical sarcoma. Excision of the tumour through trans-vaginal hysterectomy was performed, no lymphadenopathy was found, no adnexa abnormalities, and no involvement of the vaginal wall. Histological diagnosis of Malignant mixed Mullerian tumour of the cervix was made. Patient recovery was unremarkable; however she was lost to follow up. The patient's mass was initially suspected to be prolapsed uterus with decubitus ulcer but the histological results were of a malignant condition. Lack of clear management guidelines for some rare mixed tumours remains a challenge for clinicians in low resource settings.

The aim of the present study was to clarify the most effective combination of injected tracer types and injection sites in order to detect sentinel lymph nodes (SLNs) in early endometrial cancer. The study included 100 consecutive patients with endometrial cancer treated at Tohoku University Hospital between June 2001 and December 2012. The procedure for SLN identification entailed either radioisotope (RI) injection into the endometrium during hysteroscopy (55 cases) or direct RI injection into the uterine cervix (45 cases). A combination of blue dye injected into the uterine cervix or uterine body intraoperatively in addition to preoperative RI injection occurred in 69 of 100 cases. All detected SLNs were recorded according to the individual tracer and the resultant staging from this method was compared to the final pathology of lymph node metastases including para-aortic nodes. SLN detection rate was highest (96%) by cervical RI injection; however, no SLNs were detected in para-aortic area. Para-aortic SLNs were detected only by hysteroscopic RI injection (56%). All cases with pelvic lymph node metastases were detected by pelvic SLN biopsy. Isolated positive para-aortic lymph nodes were detected in 3 patients. Bilateral SLN detection rate was high (96%; 26 of 27 cases) by cervical RI injection combined with dye. RI injection into the uterine cervix is highly sensitive in detection of SLN metastasis in early stage endometrial cancer. It is a useful and safe modality when combined with blue dye injection into the uterine body. © 2013.

Medical practices in oncology are expected to be multidisciplinary, yet few articles studied how this may be concretely applied. In the present study, we evaluated the organization of two multidisciplinary committees, one for breast cancer and one for sarcoma, in a French Comprehensive Cancer Centre. Both tumours were specifically chosen so as to emphasise substantial differences in relation with incidence, histological subtypes, management strategy, and scientific evidence. Between 2003 and 2004, 404 decision processes were observed, 210 for sarcoma (26 meetings) and 194 for breast cancer (10 meetings). The number of physicians who took part in the discussions and their medical specialties were systematically noted as well as the number of contradictory discussions, medical specialties represented in these contradictory discussions and the topics of contradiction. The last measured data was whether the final committee's decision was in conformity with the referent preferences or not. All these measures were related to the referent's medical speciality and working place, to the stage of the disease and to the disease management stage. Committees' specificities concerned their organization, referent's medical specialties, the number of participants in discussions and their medical specialties. Discussions in the sarcoma committee tended to be more multidisciplinary, involving more specialties. Initial strategy proposal for one patient was modified during the discussions for 86 patients out of 210 (41%) and for 62 out of 194 (32%) respectively for sarcoma and breast cancer. However, there was no significant difference in the rate of contradictory discussions between breast cancer and sarcoma committees (32% versus 41% respectively; P = 0.08). The rates of contradictory discussions were similar for localized cancers, local relapse and metastasis disease (37%, 41% and 34% respectively; P = 0.86). The present study reports more than 30% of changes concerning strategy for patient with cancer due to multidisciplinary discussions. This indicates that, providing tumour committees are adapted to the pathologies' characteristics, they can promote a collective and multidisciplinary approach to oncology.

Uterine fluid was collected from a group of normal patients and a group of patients with menorrhagia. Heparin-like activity was detected in 34 out of 38 samples using an anti-Xa heparin assay. The heparin-like activity in uterine fluid was inhibited by adding the heparin antagonist hexadimethrine bromide to the assay. Concentrations of fibrinogen-fibrin degradation products (FDPs) were measured in five samples of uterine fluid. FDPs in the concentration detected had no effect on the anti-Xa assay. Heparin-like activity was higher in the group with menorrhagia, although the differences were not significant. Heparin-like activity increased throughout the menstrual cycle and decreased during menstruation, suggesting a possible cyclical variation in activity. There was no correlation between mast cell numbers in the endometrium and myometrium and heparin-like activity in uterine fluid and no correlation between the numbers and the stage in the menstrual cycle. In a few patients with intrauterine contraceptive devices (IUCDs) heparin-like activity was increased. PMID:687899

Primary Tumor Necrosis Predicts Distant Control in Locally Advanced Soft-Tissue Sarcomas After Preoperative Concurrent Chemoradiotherapy

Purpose: Various neoadjuvant approaches have been evaluated for the treatment of locally advanced soft-tissue sarcomas. This retrospective study describes a uniquely modified version of the Eilber regimen developed at the University of Chicago. Methods and Materials: We treated 34 patients (28 Stage III and 6 Stage IV) with locally advanced soft-tissue sarcomas of an extremity between 1995 and 2008. All patients received preoperative therapy including ifosfamide (2.5 g/m2 per day for 5 days) with concurrent radiation (28 Gy in 3.5-Gy daily fractions), sandwiched between various chemotherapy regimens. Postoperatively, 47% received further adjuvant chemotherapy. Results: Most tumors (94%) were Grade 3,more » and all were T2b, with a median size of 10.3 cm. Wide excision was performed in 29 patients (85%), and 5 required amputation. Of the resected tumor specimens, 50% exhibited high (>=90%) treatment-induced necrosis and 11.8% had a complete pathologic response. Surgical margins were negative in all patients. The 5-year survival rate was 42.3% for all patients and 45.2% for Stage III patients. For limb-preservation patients, the 5-year local control rate was 89.0% and reoperation was required for wound complications in 17.2%. The 5-year freedom-from-distant metastasis rate was 53.4% (Stage IV patients excluded), and freedom from distant metastasis was superior if treatment-induced tumor necrosis was 90% or greater (84.6% vs. 19.9%, p = 0.02). Conclusions: This well-tolerated concurrent chemoradiotherapy approach yields excellent rates of limb preservation and local control. The resulting treatment-induced necrosis rates are predictive of subsequent metastatic risk, and this information may provide an opportunity to guide postoperative systemic therapies.« less

Lymphoepithelioma-like carcinoma occurring in the reproductive organs is a rare variant of squamous cell carcinoma, and this tumor of the uterine cervix accounts for 0.7% of all primary cervical uterine neoplasms. Associations with Epstein-Barr virus (EBV) and human papilloma virus (HPV) have been demonstrated in some studies. Some investigators suggested that EBV has an important role in the initiation of lymphoepitheliomalike carcinoma in Asian women. Here we report the case of a 45-year-old Japanese woman, gravida 2 and parity 2. She was admitted due to severe atypical genital bleeding caused by uterine cervical cancer. A >60-mm tumor was detected at the uterine cervix, and no distal metastasis or swallowing of lymph nodes was revealed by magnetic resonance imaging and a computed tomography scan. The cervical cancer stage FIGO Ib2 was diagnosed, and a radical hysterectomy was performed for this malignant tumor. The in situ hybridization for EBV was negative. HVP infection was strongly suspected because the squamous cell carcinoma was observed macroscopically in the uterine cervix. The prognosis of uterine lymphoepithelioma-like carcinoma is thought to be better than those of other cervical cancer types, but careful follow-up at fixed intervals is recommended. The patient has been followed up for 4 months since her surgery, and no evidence of recurrence has been detected.

To evaluate pre-treatment serum C-reactive protein (CRP) level as a prognostic parameter in patients with adenocarcinoma of the uterine cervix. Pre-treatment CRP levels were analyzed to determine potential associations with clinicopathological parameters and to assess prognostic value in 46 patients with sole adenocarcinoma of the uterine cervix. The mean (±SD) pre-treatment serum CRP level was 5.82 (7.21) mg/l. Serum CRP concentration significantly correlated positively with age at diagnosis (p=0.001), lymphovascular space invasion (p=0.0026), recurrent disease (p=0.0001) and International Federation of Gynecology and Obstetrics (FIGO) stage (p=0.0002). In multivariate Cox regression models with age, FIGO stage, histological grade and lymph node status, elevated CRP and cancer antigen 125 levels were associated with shortened survival (p<0.05). Overall 5-year survival rate of patients with pre-treatment serum CRP level <5.0 mg/l was 100% compared to 46.9% for patients with pre-treatment CRP level ≥5.0 mg/l. Serum CRP level can be seen as an additional independent prognostic parameter in patients with the rare histological subtype adenocarcinoma of the uterine cervix.

Adequate uterine glucose metabolism is an essential part of embryo implantation and the development of an adequate utero-fetal environment. However, expression of facilitative glucose transporters (GLUTs [solute transporter family SLC2A]) and AKT/MAPK/PRKAA (PRKAA) signaling has not been described in the mouse uterine cells, to our knowledge. The objective of this study was to determine the hormonal regulation of SLC2A protein expression and AKT/MAPK/PRKAA signaling in the mouse uterine epithelial cells during estrous cycles and peri-implantation periods. SLC2As 1, 4, 8, and 9B were highly expressed in the luminal and glandular epithelia of estrous stage. In metestrous and diestrous stages, expression of SLC2As 1, 4, 8, and 9B was lower than that in proestrous stage. Levels of activated phospho-AKT (p-AKT), p-MAPK3, and p-MAPK1 also varied during the estrous cycle. Estrogen and progesterone injection in an ovariectomized mouse (delayed implantation model) resulted in a decrease and an increase, respectively, in expression of GLUTs in the luminal epithelial cells of the uterus. The expression of SLC2A1, SLC2A8, SLC2A9B, p-AKT, p-MAPK3/1, and p-PRKAA was increased in the decidual region of the implantation sites and was significantly increased in the uterus of activated implantation. Using an artificial decidualization mouse model, it was also demonstrated that expression of the same GLUTs, p-MAPK3/1, and p-PRKAA was dramatically higher in the decidualized uteri than that in the control uteri. These results suggest that steroid hormones regulate expression of uterine epithelial GLUTs possibly through AKT/MAPK/PRKAA signaling pathways and that glucose utilization may have an important role in decidualization and possibly in the maintenance of pregnancy.

Background Uterine carcinosarcomas are uncommon with about 35% not confined to the uterus at diagnosis. The survival of patients with advanced uterine carcinosarcoma is poor with pattern of failure indicating greater likelihood of upper abdominal and distant metastatic recurrence. Objectives To evaluate the effectiveness and safety of radiotherapy and/or systemic chemotherapy in the management of stage III-IV persistent or recurrent uterine carcinosarcoma. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, The Cochrane Library 2010, Issue 2, MEDLINE and EMBASE to May 2010. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials comparing adjuvant radiotherapy and/or chemotherapy in women with uterine carcinosarcoma. Data collection and analysis We independently abstracted data and assessed risk of bias. We pooled hazard ratios (HRs) for overall and progression-free survival and risk ratios (RRs) comparing adverse events in women who received radiotherapy and/or chemotherapy in meta-analyses. Main results Three trials (579 women, of whom all were assessed at the end of the trials) met the inclusion criteria. Two trials (373 women with stage III-IV persistent or recurrent disease) found that women who received combination therapy had a significantly lower risk of death and disease progression than women who received single agent ifosfamide. There was no statistically significant difference in all reported adverse events, with the exception of nausea and vomiting, which affected significantly more women in the combination therapy group than in the ifosamide group. One trial found no statistically significant difference in the risk of death and disease progression in women who received whole abdominal irradiation and chemotherapy, after adjustment for age and FIGO stage (HR = 0.71, 95% CI 0.48 to 1.05 and HR = 0.79, 95% CI 0.53 to 1.18 for overall survival and progression-free survival respectively). There was no statistically significant difference in all reported adverse events, with the exception of haematological and neuropathy morbidities, which affected significantly fewer women in the whole body irradiation group than in the chemotherapy group (RR = 0.02, 95% CI 0.00 to 0.16). Authors’ conclusions The results of this review are limited to two trials. In the primary treatment/first line therapy of advanced stage metastatic uterine carcinosarcoma, as well as in recurrent disease, adjuvant combination chemotherapy with ifosfamide and paclitaxel should be considered. None of the included studies reported on quality of life. PMID:21249682

Three homosexual male patients with biopsy-proved Kaposi's sarcoma were classified as having the acquired immune deficiency syndrome (AIDS) by Centers for Disease Control criteria when first seen in 1983 and 1984. These patients, however, differed from most patients with AIDS and Kaposi's sarcoma in having normal CD4 cell numbers and normal CD4:CD8 ratio. Furthermore, these immunologic parameters remained normal for eight to 24 months of follow-up, and the disease did not progress. Results of recent testing of serum from these patients were negative for HTLV-III/LAV antibodies. The Kaposi's sarcoma was limited to skin (stage I tumors) and the patients did not have persistent lymphadenopathy, fever, night sweats, or weight loss. In contrast to AIDS, the serum immunoglobulin levels (IgG, IgA, IgM) and number of B cells that were spontaneously forming immunoglobulin were within normal range with no evidence of polyclonal activation. The lymphocyte proliferative responses to phytohemagglutinin and Candida were reduced in two of the three patients, and skin test anergy was observed in the two patients tested. These findings are not frequently encountered in other healthy, homosexually active men or in classic Kaposi's sarcoma. They may be indicative of functional T cell changes (without numerical changes) induced by factors other than HTLV-III/LAV virus, which made these homosexually active men susceptible to development of low-grade Kaposi's sarcoma lesions.

Sarcomas are a relatively rare cancer, but often incurable at the late metastatic stage. Oncolytic immunotherapy has gained attention over the past years, and a wide range of oncolytic viruses have been delivered via intratumoral injection with positive safety and promising efficacy data. Here, we report preclinical and clinical results from treatment of sarcoma with oncolytic adenovirus Ad5/3-D24-GMCSF (CGTG-102). Ad5/3-D24-GMCSF is a serotype chimeric oncolytic adenovirus coding for human granulocyte-macrophage colony-stimulating factor (GM-CSF). The efficacy of Ad5/3-D24-GMCSF was evaluated on a panel of soft-tissue sarcoma (STS) cell lines and in two animal models. Sarcoma specific human data were also collected from the Advanced Therapy Access Program (ATAP), in preparation for further clinical development. Efficacy was seen in both in vitro and in vivo STS models. Fifteen patients with treatment-refractory STS (13/15) or primary bone sarcoma (2/15) were treated in ATAP, and treatments appeared safe and well-tolerated. A total of 12 radiological RECIST response evaluations were performed, and two cases of minor response, six cases of stable disease and four cases of progressive disease were detected in patients progressing prior to virus treatment. Overall, the median survival time post treatment was 170 days. One patient is still alive at 1,459 days post virus treatment. In summary, Ad5/3-D24-GMCSF appears promising for the treatment of advanced STS; a clinical trial for treatment of refractory injectable solid tumors including STS is ongoing. © 2013 UICC.

Gastric type mucinous endocervical adenocarcinomas of the uterine cervix (GAC) are a newly classified mucinous subtype with morphologically in 2014, WHO. They have a much more aggressiveness and show unusual metastatic patterns compared to usual type endocervical adenocarcinoma. They tend to present at higher stage and even in stage I, they have worse survival. Therefore, differential diagnosis of GAC from the usual type of endocervical adenocarcinoma is very important because they are related to a significant risk of recurrence and decreased 5-year disease-specific survival. Besides, GACs are mostly not associated with human papillomavirus (HPV) infection and p16 immunohistochemistry is also typically negative in GAC that is HPV-unassociated tumor. We report a very rare and interesting case of stage IB1 GAC with negative HPV DNA and p16.

For both cervical cancer (UCC) and endometrial cancer (EMC) there are no effective prognostic markers. In this study, we evaluated HIG2 protein expression in 332 uterine cancers (186 UCCs and 146 EMCs) and examined the relationship between HIG2 protein expression and clinical factors, including prognosis. Totally, HIG2 expression was detected in 58% of UCC and 66% of EMC. However, there was no significant relationship between HIG2 expression and age, clinical stage and histology in either UCC or EMC. In addition, HIG2 protein expression was not related to prognosis of UCC or EMC. The positivity rate of HIG2 protein was 56% and 61% in early-stage UCC and EMC, respectively and 67% in non-squamous cell carcinoma of UCC. The positivity rate of HIG2 protein was high even in early-stage UCC and EMC

Comparison of the AJCC, MSTS, and Modified Spanier Systems for Clinical and Pathologic Staging of Osteosarcoma.

The prognostic performance of the 2 most commonly used staging systems for skeletal sarcoma (the American Joint Committee on Cancer [AJCC] and Musculoskeletal Tumor Society [MSTS] systems) have never been compared analytically. Another staging system originally proposed by Spanier has not yet been validated. Given the recent release of the 8th edition of the AJCC Cancer Staging Manual, this study was designed to directly compare these anatomic staging systems in a series of 153 high-grade, intramedullary osteosarcomas. Kaplan-Meier curves were plotted and pairwise comparisons between each stage category were performed. Predictive accuracy of each staging system for determining 5-year disease-free survival was evaluated by comparing areas under receiver-operating characteristic curves generated from logistic regression analysis. Multiple concordance indices were calculated using bootstrapping methods (200 replications). ρk and R were estimated as measures of the variation in survival outcomes explained by the regression models. The AJCC, MSTS, and a modified version of the Spanier staging systems showed similar discriminatory abilities and no significant differences in the levels of contrast between different tumor stages across staging systems. Addition of T-category information from each staging system contributed significant prognostic information compared with a Cox proportional hazard regression model consisting only of the presence or absence of metastatic disease as a measure of disease extent. Concordance indices and predictive accuracy for 5-year disease-free survival were not significantly different among the different staging systems either. Similar findings were observed after accounting for other important prognostic variables. Additional studies are necessary to determine performance parameters of each staging system for other types of skeletal sarcoma. Prognostic performance of osteosarcoma staging systems would also be improved by incorporating nonanatomic prognostic variables into staging algorithms.

The capillary morphogenesis gene 2 (CMG2), also known as the anthrax toxin receptor 2 (ANTXR2), is a transmembrane protein putatively involved in extracellular matrix (ECM) adhesion and tissue remodeling. CMG2 promotes endothelial cell proliferation and exhibits angiogenic properties. Its downregulation is associated with a worsened survival of breast carcinoma patients. Aim of this study was to analyze the CMG2 mRNA and protein expression in soft tissue sarcoma and their association with patient outcome. CMG2 mRNA was measured in 121 tumor samples of soft tissue sarcoma patients using quantitative real-time PCR. CMG2 protein was evaluated in 52 tumor samples by ELISA. CMG2 mRNA was significantly correlated with the corresponding CMG2 protein expression (rs = 0.31; p = 0.027). CMG2 mRNA expression was associated with the mRNA expressions of several ECM and tissue remodeling enzymes, among them CD26 and components of the uPA system. Low CMG2 mRNA expression was correlated with a worsened patients’ disease-specific survival in Kaplan-Meier analyses (mean patient survival was 25 vs. 96 months; p = 0.013), especially in high-stage tumors. A decreased CMG2 expression is a negative prognostic factor for soft tissue sarcoma patients. CMG2 may be an interesting candidate gene for the further exploration of soft tissue sarcoma genesis and progression. PMID:29215551

Objective Uterine carcinosarcoma (CS) is a rare uterine tumor with an extremely poor prognosis. In the adjuvant setting, efficacy has been shown with radiotherapy (RT), systemic chemotherapy, or both. This is the first report describing the efficacy and toxicity of adjuvant ifosfamide or ifosfamide plus cisplatin “sandwiched” with RT in patients with surgically staged and completely resected uterine carcinosarcoma. Methods Women with surgically staged CS with no gross residual disease were initially administered ifosfamide (1.2 g/m2/day × 5 days) with cisplatin (20 mg/m2/day × 5 days) every 3 weeks for 3 cycles followed by pelvic external beam RT and brachytherapy followed by 3 additional cycles of ifosfamide (1.0 g/m2/day) with cisplatin (20 mg/m2/day × 5 days) every 3 weeks. Similar to the GOG trial in recurrent CS (Sutton et al, 2000), the addition of cisplatin added toxicity without additional efficacy, so mid-study, the cisplatin was eliminated from the regimen. Toxicities were recorded and disease-free survival (DFS) was calculated with Kaplan-Meier statistical methods. Results In total, 12 patients received ifosfamide and cisplatin and 15 patients received ifosfamide alone, both ‘sandwiched’ with RT. The median follow up was 35.9 months (range 6–88). The 2 year DFS was similar in both the ifosfamide/cisplatin and ifosfamide groups (log-rank p = 0.16), so they were combined for analysis. 19 patients (70%) completed the protocol. As expected, stage 1 patients had a better 2-year DFS (18.75 ± 1.12 months; log-rank p = 0.008 when compared to stages 2, 3, 4). Also, in stages 2, 3 and 4 patients, the DFS was 15.81 ± 1.73 months. Grade 3/4 neutropenia, anemia and thrombocytopenia occurred in 18%, 4% and 4% of cycles, respectively. Conclusions Ifosfamide “sandwiched” with RT appears to be an efficacious regimen for surgically staged CS patients with no residual disease, even in patients with advanced stage. The addition of cisplatin to the regimen added toxicity without improving efficacy. Even with ifosfamide alone, the efficacy of this ‘sandwich’ regimen comes with a moderate but tolerable toxicity profile. PMID:22055846

Soft tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin that display a heterogenous mix of clinical and pathologic characteristics. STS can develop from fat, muscle, nerves, blood vessels, and other connective tissues. The evaluation and treatment of patients with STS requires a multidisciplinary team with demonstrated expertise in the management of these tumors. The complete NCCN Guidelines for STS provide recommendations for the diagnosis, evaluation, and treatment of extremity/superficial trunk/head and neck STS, as well as intra-abdominal/retroperitoneal STS, gastrointestinal stromal tumors, desmoid tumors, and rhabdomyosarcoma. This portion of the NCCN Guidelines discusses general principles for the diagnosis, staging, and treatment of STS of the extremities, superficial trunk, or head and neck; outlines treatment recommendations by disease stage; and reviews the evidence to support the guidelines recommendations.

Leiomyosarcomas are malignant mesenchymal tumors that recapitulate smooth muscle cell differentiation. Tumors are characterized by a genetic heterogeneity with complex karyotypes without a tumor-specific genetic aberration. Their pathobiology is still poorly understood and no specific targeted treatment is currently available for these aggressive tumors. For six leiomyosarcomas, cells were cultured and analyzed by combined binary ratio labeling fluorescence in situ hybridization (COBRA-FISH) karyotyping. A t(6;14) was identified in two cases. FISH breakpoint mapping of case L1339 reveals a breakpoint at chromosome 6p21.31 close to HMGA1, and a small deletion was observed on the distal side of the gene. A small homozygous deletion was also found in the breakpoint region of chromosome 14q24.1 involving ACTN1. The second case revealed a der(6)t(6;14)(p21.1;q21.3), with a duplication adjacent to the breakpoint at chromosome 6. Confirmatory FISH revealed a second leiomyosarcoma with an aberration at 14q24.1. Alterations at this locus were found in 5% (2 of 39) of the leiomyosarcomas in this study. The other identified breakpoints appeared to be non-recurrent, because they were not detected in other leiomyosarcomas, uterine leiomyomas, undifferentiated spindle cell sarcomas, or undifferentiated pleomorphic sarcomas.

Pre-eclampsia (PE), a hypertensive disorder of pregnancy, is detrimental to both mother and foetus. There is currently no effective treatment, but we have shown that Sildenafil Citrate (SC) improve various foetal outcomes in N ω -nitro-L arginine methyl ester (L-NAME) rat model of PE. Therefore, we aimed to investigate the effects of SC on a uterine angiogenic status and serum inflammatory markers in an L-NAME rat model of PE. One hundred and twenty adult nulliparous pregnant female Sprague-Dawley rats were used for the study. These were divided into five equal groups; the pregnant control, early and late onset PE and respective SC treated animals. Hypertension was manifested by considerably increased systolic blood pressure and placental lipid peroxidative marker (thiobarbituric acid reactive substances) and also we assessed the activities of plasma nitric oxide level, serum inflammatory marker (TGF-β and IFN-γ) and uterine angiogenic status (VEGF and sFlt-1) at two stages of PE. The administration of SC decreased systolic blood pressure, placental lipid peroxidation product and altered uterine angiogenic status; increased plasma nitric oxide levels in an early and late onset L-NAME model of PE. In addition, histological findings of SC treated preeclamptic rat placenta support the biochemical findings of this study. Our findings revealed that SC enhanced plasma NO levels and uterine angiogenic status in an L-NAME model of PE at two gestational stages. Copyright © 2016 Elsevier B.V. All rights reserved.

To compare the efficacy and tolerance of adjuvant chemotherapy and radiotherapy delivered in sequential (chemotherapy followed by radiation) versus "sandwich" fashion (chemotherapy, interval radiation, and remaining chemotherapy) after surgery in patients with FIGO stage III uterine endometrioid adenocarcinoma. From 2004 to 2011, we identified 51 patients treated at our institution fitting the above criteria. All patients received surgical staging followed by adjuvant chemoradiation (external-beam radiation therapy (EBRT) with or without high-dose rate (HDR) vaginal brachytherapy (VB)). Of these, 73% and 27% of patients received their adjuvant therapy in sequential and sandwich fashion, respectively. There were no significant differences in clinical or pathologic factors between patients treated with either regimen. Thirty-nine (76%) patients had stage IIIC disease. The majority of patients received 6 cycles of paclitaxel with carboplatin or cisplatin. Median EBRT dose was 45 Gy and 54% of patients received HDR VB boost (median dose 21 Gy). There were no significant differences in the estimated 5-year overall survival, local progression-free survival, and distant metastasis-free survival between the sequential and sandwich groups: 87% vs. 77% (p=0.37), 89% vs. 100% (p=0.21), and 78% vs. 85% (p=0.79), respectively. No grade 3-4 genitourinary or gastrointestinal toxicities were reported in either group. There was a trend towards higher incidence of grade 3-4 hematologic toxicity in the sandwich group. Adjuvant chemoradiation for FIGO stage III endometrioid uterine cancer given in either sequential or sandwich fashion appears to offer equally excellent early clinical outcomes and acceptably low toxicity.

Percutaneous vascular embolization plays an important role in the management of various gynecologic and obstetric abnormalities. Transcatheter embolization is a minimally invasive alternative procedure to surgery with reduced morbidity and mortality, and preserves the patient's future fertility potential. The clinical indications for transcatheter embolization are much broader and include many benign gynecologic conditions, such as fibroid, adenomyosis, and arteriovenous malformations (AVMs), as well as intractable bleeding due to inoperable advanced-stage malignancies. The most well-known and well-studied indication is uterine fibroid embolization. Uterine artery embolization (UAE) may be performed to prevent or treat bleeding associated with various obstetric conditions, including postpartum hemorrhage (PPH), placental implantation abnormality, and ectopic pregnancy. Embolization of the uterine artery or the internal iliac artery also may be performed to control pelvic bleeding due to coagulopathy or iatrogenic injury. This article discusses these gynecologic and obstetric indications for transcatheter embolization and reviews procedural techniques and outcomes. PMID:29379246

Purpose: The purpose of this study was to develop a nomogram capable of predicting the probability of 5-year survival after radical radiotherapy (RT) without chemotherapy for uterine cervical cancer. Methods and Materials: We retrospectively analyzed 549 patients that underwent radical RT for uterine cervical cancer between March 1994 and April 2002 at our institution. Multivariate analysis using Cox proportional hazards regression was performed and this Cox model was used as the basis for the devised nomogram. The model was internally validated for discrimination and calibration by bootstrap resampling. Results: By multivariate regression analysis, the model showed that age, hemoglobin levelmore » before RT, Federation Internationale de Gynecologie Obstetrique (FIGO) stage, maximal tumor diameter, lymph node status, and RT dose at Point A significantly predicted overall survival. The survival prediction model demonstrated good calibration and discrimination. The bootstrap-corrected concordance index was 0.67. The predictive ability of the nomogram proved to be superior to FIGO stage (p = 0.01). Conclusions: The devised nomogram offers a significantly better level of discrimination than the FIGO staging system. In particular, it improves predictions of survival probability and could be useful for counseling patients, choosing treatment modalities and schedules, and designing clinical trials. However, before this nomogram is used clinically, it should be externally validated.« less

Chemotherapy options for resistant advanced-stage sarcomas are limited and in most cases disappointing. In a phase II study, we treated 26 consecutive patients with refractory advanced sarcoma with ifosfamide and etoposide combination chemotherapy. All patients had received prior doxorubicin- and/or cyclophosphamide-based chemotherapies. Seventeen patients were male and 9 were female. The patients' median age was 35 years (range: 19-67 years). A total of 24 patients were eligible for evaluation of responses. Seven patients had a complete response (CR) (29.1%), 3 had a partial response (PR) (12.5%), 3 had stable disease (SD) (12.5%), and 11 had progressive disease (PD) (45.9%). An overall 41.6% objective response was achieved. Median time to treatment failure was 13.3 months. A total of 108 cycles of therapy were evaluable for evaluation of toxicity. Myelosuppression, observed in 55.5% of the treatment courses, was the major dose-limiting toxicity. Nausea and vomiting, seen in 64% of the courses, were the most important nonhematological side effects. Alopecia was almost universal. Hemorrhagic cystitis was observed in only 1 patient. We have concluded that the combination of ifosfamide, mesna, and etoposide is effective in advanced refractory sarcomas, and has acceptable toxicity.

We aimed to evaluate the relative prognostic impact of the most common variant histologies on disease-specific survival (DSS) in patients undergoing radical cystectomy. The Surveillance, Epidemiology, and End Result database was used to identify patients who underwent radical cystectomy for bladder cancer from 1990 to 2007. Patients with urothelial cell carcinoma (UCC), squamous cell carcinoma (SCC), adenocarcinoma (AC), sarcoma, small cell carcinoma, signet ring carcinoma, and spindle cell carcinoma were included in the study. Multivariable analysis was performed using Cox proportional hazards model to assess independent predictors of disease-specific survival (DSS). Mortality rates were estimated using Kaplan-Meier analyses. A total of 14,130 patients met inclusion criteria with the following histologies: UCC (90.1%), SCC (4.6%), AC, (2.3%), sarcoma (0.8%), small cell carcinoma (0.8%), signet ring carcinoma (0.5%), and spindle cell carcinoma (0.9%). Three-year DSS was most favorable in patients with UCC (63.7%; 95% confidence interval [62.9%-64.8%]) and AC (65.3% [59.3%-70.6%]), whereas 3-year DSS was the least favorable for small cell carcinoma (41.6% [31.3%-51.6%]) and sarcoma (45.4% [35.1%-55.1%]). In the multivariable analysis, independent predictors of DSS were age, marital status, grade, T-stage, N-stage, and variant histology. With respect to UCC, there was an increased risk of disease-specific death associated with all variants except AC. Sarcoma and spindle cell carcinoma were associated with the highest risk of death. With the exception of AC, the most common variant bladder cancer histologies are all independently associated with worse DSS relative to UCC in patients undergoing radical cystectomy.

To assess whether contemporary adjuvant management of early stage uterine carcinosarcoma (CS) produces equal outcomes as in uterine serous carcinoma (USC). We reviewed 172 women treated from 2000 to 2011 for stage I-II USC (n=112, 65%) or CS (n=60, 35%). Adjuvant therapy was initiated in 154 (90%) patients, with 111 patients receiving intravaginal radiotherapy (IVRT)/chemotherapy. Median follow up was 4.6 years for surviving patients. Characteristics for USC vs. CS did not differ significantly by age ≥60, pelvic or para-aortic node sampling, stage, lymphovascular invasion, chemotherapy use, RT use or omission of adjuvant therapy. Outcomes were better for USC vs. CS in 5-year actuarial rates of recurrence [17% (C.I. 10-25%) vs. 45% (C.I. 31-59%), p<0.001],disease-related mortality (DRM) [11% (5-17%) vs. 30% (16-44%), p=0.016], and all-cause mortality [12% (C.I. 6-18%) vs. 34% (C.I. 20-48%), p=0.007]. In multivariable analysis, CS histology remained a significant predictor of risk for recurrence [HR 3.1 (C.I. 1.7-5.7), p<0.001], DRM [HR 2.4 (C.I. 1.1-5.1), p=0.024], and all-cause mortality [HR 2.4 (C.I. 1.2-4.8), p=0.012]. On sub-group analysis of 111 patients (77 USC, 34 CS) able to receive IVRT/chemotherapy, CS no longer was associated significantly with increased recurrence (29% vs. 15%, p=0.18), DRM (22% vs. 10%, p=0.39), or all-cause mortality (22% vs. 10%, p=0.45). CS was associated with worse outcomes than USC. However, that difference was not maintained in patients able to receive IVRT and chemotherapy. While intriguing, this result may be due in part to selection against rapid early relapsing CS patients in this group. Copyright © 2014 Elsevier Inc. All rights reserved.

The window of implantation is defined by the inhibition of uterine epithelial proliferation, structural epithelial cell remodeling, and attenuated estrogen (E2) response. These changes occur via paracrine signaling between the uterine epithelium and stroma. Because implantation defects are a major cause of infertility in women, identifying these signaling pathways will improve infertility interventions. Bone morphogenetic proteins (BMPs) are TGF-β family members that regulate the postimplantation and midgestation stages of pregnancy. In this study, we discovered that signaling via activin-like kinase 3 (ALK3/BMPR1A), a BMP type 1 receptor, is necessary for blastocyst attachment. Conditional knockout (cKO) of ALK3 in the uterus was obtained by producing Alk3flox/flox-Pgr-cre–positive females. Alk3 cKO mice are sterile and have defects in the luminal uterine epithelium, including increased microvilli density and maintenance of apical cell polarity. Moreover, Alk3 cKO mice exhibit an elevated uterine E2 response and unopposed epithelial cell proliferation during the window of implantation. We determined that dual transcriptional regulation of Kruppel-like factor 15 (Klf15), by both the transforming growth factor β (TGF-β) transcription factor SMAD family member 4 (SMAD4) and progesterone receptor (PR), is necessary to inhibit uterine epithelial cell proliferation, a key step for embryo implantation. Our findings present a convergence of BMP and steroid hormone signaling pathways in the regulation of uterine receptivity. PMID:26721398

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide and accounts for one third of maternal deaths in low-income and middle-income countries. PPH can be prevented by active management of the third stage of labor (AMTSL), a series of steps recommended by the World Health Organization to be performed by skilled birth attendants (SBAs). Task shifting in the AMTSL step of uterotonic drugs administration to community health workers, traditional birth attendants and self-administration has been investigated as a strategy to increase access to quality obstetric care considering persistent SBA and facility-based delivery shortages. The aim of this study is to assess task shifting in the final step of AMTSL and compare uterine tonus assessment by a SBA to self-assessment. The study is an individual-level two-arm non-inferiority randomized controlled trial (RCT). A total of 800 women will be recruited in Korle Bu Teaching Hospital in Accra, Ghana. Adult women in labor at term with an expected vaginal delivery who received antenatal instructions for self-assessment of uterine tonus will be eligible for inclusion. Women with an increased risk for PPH will be excluded. Women will be randomized to uterine tone assessment by a skilled birth attendant (midwife) or uterine tone self-assessment (with the safety back-up of a midwife present in case of PPH or uterine atony). Postpartum blood loss will be measured through weighing of disposable mats. The main study endpoints are PPH (≥500 ml blood loss), severe PPH (≥1000 ml blood loss), mean blood loss, and routine maternal and neonatal outcomes. Participants and caregivers will not be blinded given the nature of the intervention. A reduction of PPH-related maternal mortality requires full implementation of AMTSL. Task shifting of uterine tone assessment may contribute to increased AMTSL implementation in (clinical) settings where SBAs capacity is constrained.

Little is known about the presence of mycoplasmas in the genital tracts of domestic and stray bitches or in the vaginas of ovariohysterectomized (OHE) bitches. Moreover, to our knowledge, there has been no research to investigate the presence of canine vaginal mycoplasmas during the different stages of the reproductive cycle. We investigated the occurrence of mycoplasmas in the vaginas of healthy domestic and stray intact bitches, to correlate their presence with specific stages of the reproductive cycle, and to compare them with those in OHE bitches. We also investigated the presence of uterine mycoplasmas. Mycoplasmas were isolated from 41 of 122 vaginal swabs (34%) from domestic (27%) and stray (39%) bitches. Mycoplasma canis was the most commonly identified species ( n = 26; 63%), and was detected in both intact (60%) and OHE (73%) bitches. Mycoplasma isolates from the vaginas of healthy bitches did not vary during the various stages of the estrous cycle. Mycoplasmas were not detected in uterine samples.

The aim of this study was to determine signs of subclinical endometritis found by ultrasound that are associated with reduced fertility in dairy cows. The maximum diameter of the uterine lumen was determined by ultrasound in 324 cows without clinical signs of endometritis after evaluation of the genital tract 21 to 27 days postpartum. Cows were classified into healthy or with subclinical endometritis by three threshold values for the maximum uterine lumen diameter of 0.2 cm, 0.5 cm or 0.8 cm. Examinations by rectal palpation and ultrasound as well as classifications were repeated 14 days later. In addition, ovaries were scanned by ultrasound to determine the stage of the estrous cycle. In a subgroup of 103 cows the echotexture of the uterus and its contents was evaluated. In these cows the diagnosis of subclinical endometritis was performed by a scoring system. The diameter of the uterine lumen was significantly affected by stage of the estrous cycle at the time of examination. However, no effects were found for the stage of the cycle at the time of examination on subsequent reproductive performance. A uterine lumen with a maximum diameter of more than 0.2 cm showed a significant negative association with conception rate and proportion of cows pregnant. Classification based on higher threshold values did not reveal an association with reproductive performance. Echogenic content in the uterus also decreased reproductive performance. A classification based on the echotexture of the uterus and its contents revealed significant differences between healthy cows and cows with subclinical endometritis regarding the proportion of cows inseminated and pregnant. The results of this study showed that the diagnostic of bovine endometritis should be broadend by ultrasonography. The definition of subclinical endometritis diagnosed by means of ultrasonography has to be evaluated in further studies.

Uterine manipulators are a useful adjunct for robotic-assisted radical hysterectomy (RARH), but some surgeons avoid their use for fear of altering pathology or interpretation of lymphovascular space involvement (LVSI). We retrospectively compared clinico-pathological data and tumor pathology from patients with cervical cancer operated by laparotomy vs. RARH. Charts from cervical cancer patients who underwent radical hysterectomy from January-1997 to June-2010 were reviewed for tumor histology, grade, FIGO stage, lymph node status, LVSI, depth of invasion, and tumor size. A ConMed V-Care® uterine manipulator was used in all robotic cases. H&E stained slides from 20 robotic and 24 open stage IB1 cases with LVSI reported in the original pathology were re-reviewed by a blinded pathologist for analysis of tissue artifacts and LVSI. Two-hundred-thirty-six cases (185 open, 51 robotic) with stages IA2, IB1 and IB2 cervical cancer were reviewed. No significant differences in histology (squamous cell carcinoma, 65% vs. 51%; p=0.1), IB1 lesion size (≤2 cm, 62% vs. 61%, p>0.1), LVSI (34% vs. 39%, p>0.1), and depth of stromal invasion (p>0.1) was found between open and robotic groups. Histologic examination of all IB1 cervical carcinomas revealed a higher degree of surface disruption [45% (9/20) vs. 12.6% (3/24), p=0.038] and artifactual "parametrial carryover" [65% (13/20) vs. 29% (7/24), p=0.037] in robotic vs. open groups, respectively, but no significant differences in the rate of LVSI. RARH cases that utilized a uterine manipulator did not show any clinico-pathological differences in depth of invasion, LVSI, or parametrial involvement compared to open cases.

This study was focused to understand how endometriosis altered the uterine and cervical bacterial community. Urogenital swabs and uterine washes were collected from 19 pre-menopausal women undergoing laparoscopic surgery for pelvic pain, suspected endometriosis (experimental n = 10), and women undergoing laparoscopic surgery for benign ovarian/uterine conditions (control n = 9). Patients were followed for the next year and repeat cervical swabs were obtained. Bacterial community composition was assessed from these samples using Illumina next generation 16Smore » rRNA amplicon sequencing. Bacterial communities were significantly different between sample sites, the uterus and cervix, and stage III endometriosis resulted in significant alterations in the cervical bacterial community. Both bacterial richness and phylogenetic diversity increased in association with stage III endometriosis. Surgical intervention resulted in a stabilized cervical bacterial community for a short period of time. Lastly, bacterial community profiling may provide a useful diagnostic tool for identifying endometriosis in asymptomatic, infertile women in a clinical setting.« less

Nerve-sparing techniques to avoid bladder dysfunction in abdominal radical hysterectomy have been established during the past two decades, and they have been applied to radical trachelectomy. Although trachelectomy retains the uterine corpus, no report mentions the preservation of uterine branches of pelvic nerves. The aim of the present study was to introduce and discuss our unique concept for preserving them. Four cases with FIGO stage Ia2-Ib1 cervical cancer, in which preservation of uterine branches of the pelvic nerves was attempted, are presented. Operative procedures basically followed the previously reported standard approaches for nerve-sparing radical hysterectomy or trachelectomy, except for some points. Before resection of the sacrouterine ligament, the hypogastric nerve was first identified and translocated laterally. Subsequently, the uterine branches of the pelvic nerve were identified as a continuation of the hypogastric nerve and could be scooped with forceps by detachment of the surrounding connective tissues. Further detachment toward the uterine corpus enabled them to be completely separated from the cervix. This separation was extended up to the level of the junction of the upper and lower branches of the uterine artery. Thereafter, standard resection of the parametrium and paracolpium was performed, followed by cervical resection when it was confirmed that the isolated uterine branches of the pelvic nerves were safely translocated and preserved. There were no recurrences of cancer in these patients. Uterine branches of autonomic nerves can be safely preserved, and the procedure may be considered one of the nerve-sparing techniques for radical abdominal trachelectomy, which may hopefully improve the reproductive outcomes of this operation, although it needs to be evaluated with more patients.

Primary malignant lymphoma of the female genital tract is an extremely rare clinical entity. We report a case of primary non-Hodgkin lymphoma of the uterine cervix. A 68-year-old woman presented with abnormal genital bleeding in May 2002. A coloposcopic examination revealed a mass in the uterine cervix. Magnetic resonance imaging showed a bulky cervical tumor(7.5 x 8 cm)invading the right parametrium and adjacent levator ani muscle. Involvement of pelvic lymph nodes was also observed. The uterine lesion exhibited homogenous hypointensity on T1 weight image and isointense to hyperintense on T2-weight image. No other lesions were detected by the whole-body computed tomography, gallium scintigraphy, and bone marrow examination. Although cytology of the smear from the uterine cervix was nondiagnostic, the histologic examination of the punch biopsy material showed a diffuse proliferation of atypical lymphoid cells. Immunophenotypic studies revealed tumor cells were positive for CD19, CD20, CD30, and k-chain. A diagnosis of diffuse large B-cell lymphoma of the uterine cervix, clinical stage IIE was made. The patient was treated with 6 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone(CHOP)chemotherapy followed by the involved field irradiation. She remains alive and free of disease more than 5 years after the diagnosis.

INTRODUCCION: Cancer is one of the main causes of death worldwide. In Mexico it represents the third cause of death. OBJECTIVE. To know the frequency and distribution of the malignancies diagnosed in Mexico during 10 years. From the data-base of the histopathological register of malignant neoplasms in Mexico, was obtained a descriptive analysis from the period 1993-2002. The variables included were: city and federative entity of residence, age, sex, anatomical region and histopathologic diagnosis. From the 12 more common malignant neoplasms a descriptive demographic analysis was performed adjusted by four regions: Center, North, South and Federal District. A total of 767,464 cases with cancer were reported. In order of frequency were: cervix-uterine cancer, breast cancer, prostate cancer, lymphomas, colorectal cancer, gastric cancer, sarcomas, ovary cancer, lung cancer, leukemias, urinary bladder cancer and uterine body. Seventy-two percent were diagnosed in women and 28% in men, the reason for a ratio W:M of 2.5:1. The states more developed and industrialized, near to United States had the majority of cases from breast, prostate, ovary and lung cancer. There is a distinctive distribution type of malignant tumors in Mexico, according to the region of residence. It absolutely is necessary to developed population based cancer registries. These are the best instruments to better understand the magnitude of cancer, and evaluate incidence, survival and mortality.

The Sarcoma Policy Checklist was created by a multidisciplinary expert group to provide policymakers with priority areas to improve care for sarcoma patients. This paper draws on this research, by looking more closely at how France, Germany, Italy, Spain, Sweden and the United Kingdom are addressing each of these priority areas. It aims to highlight key gaps in research, policy and practice, as well as ongoing initiatives that may impact the future care of sarcoma patients in different European countries. A pragmatic review of the published and web-based literature was undertaken. Telephone interviews were conducted in each country with clinical and patient experts to substantiate findings. Research findings were discussed within the expert group and developed into five core policy recommendations. The five identified priority areas were: the development of designated and accredited centres of reference; more professional training; multidisciplinary care; greater incentives for research and innovation; and more rapid access to effective treatments. Most of the countries studied have ongoing initiatives addressing many of these priorities; however, many are in early stages of development, or require additional funding and resources. Gaps in access to quality care are particularly concerning in many of Europe's lower-resourced countries. Equitable access to information, clinical trials, innovative treatments and quality specialist care should be available to all sarcoma patients. Achieving this across Europe will require close collaboration between all stakeholders at both the national and European level.

The incidence of central venous catheter (CVC)-related complications reported in pediatric sarcoma patients is not established as reports in available literature are limited. The analysis of risk factors is part of the strategy to reduce the incidence of CVC complications. The objective of this study was to determine the incidence of CVC complications in children with bone sarcomas and if defined clinical variables represent a risk factor. During an 8-year period, 155 pediatric patients with bone sarcomas were prospectively followed up for CVC complications. Incidence and correlation with clinical features including gender, age, body mass index, histology, disease stage, and use of thromboprophylaxis with low-molecular-weight heparin were analyzed. Thirty-three CVC complications were recorded among 42 687 CVC-days (0.77 per 1000 CVC-days). No correlation between the specific clinical variables and the CVC complications was found. A high incidence of CVC-related sepsis secondary to gram-negative bacteria was observed. The analysis of CVC complications and their potential risk factors in this sizable and relatively homogeneous pediatric population with bone sarcomas has led to the implementation of a multimodal approach by doctors and nurses to reduce the incidence and morbidity of the CVC-related infections, particularly those related to gram-negative bacteria. As a result of this joint medical and nursing study, a multimodal approach that included equipping faucets with water filters, the reeducation of doctors and nurses, and the systematic review of CVC protocol was implemented.

The majority of human sarcomas, particularly soft tissue sarcomas, are relatively resistant to traditional cytotoxic therapies. The proof-of-concept study by Ray-Coquard et al., using the Nutlin human double minute (HDM)2-binding antagonist RG7112, has recently opened a new chapter in the molecular targeting of human sarcomas. In this review, the authors discuss the challenges and prospective remedies for minimizing the significant haematological toxicities of the cis-imidazole Nutlin HDM2-binding antagonists. Furthermore, they also chart the future direction of the development of p53-reactivating (p53-RA) drugs in 12q13-15 amplicon sarcomas and as potential chemopreventative therapies against sarcomagenesis in germ line mutated TP53 carriers. Drawing lessons from the therapeutic use of Imatinib in gastrointestinal tumours, the authors predict the potential pitfalls, which may lie in ahead for the future clinical development of p53-RA agents, as well as discussing potential non-invasive methods to identify the development of drug resistance. Medicinal chemistry strategies, based on structure-based drug design, are required to re-engineer cis-imidazoline Nutlin HDM2-binding antagonists into less haematologically toxic drugs. In silico modelling is also required to predict toxicities of other p53-RA drugs at a much earlier stage in drug development. Whether p53-RA drugs will be therapeutically effective as a monotherapy remains to be determined.

Fine structure of the uterus in tapeworm Tetrabothrius erostris (Cestoda: Tetrabothriidea).

PubMed

Korneva, Janetta V; Jones, Malcolm K; Kuklin, Vadim V

2014-12-01

The uterine organization in Tetrabothrius erostris (Tetrabothriidea) was investigated by the methods of transmission and scanning electron microscopy. In sexually mature proglottids, the uterine wall consists of a syncytial epithelium (1.4-2.5 μm thick, except in regions containing nuclei). The ribosomes, mitochondria and numerous cisternae of granular endoplasmic reticulum with concentric or parallel profiles with electron lucent material are observed in the epithelium. The uterine wall is characterized by the abundance of lipid droplets that are localized inside the long protrusions of the uterine epithelium (called fungiform papillae) up to 15-17 μm and in the surrounding medullary parenchyma. The protrusions with lipid droplets in the proximal ends of the uterus are located closely to each other. A basal matrix (up to 0.6 μm thick) supports the uterine epithelium. The musculature consisting of 1-2 muscle layers is well developed; large myocytons are connected with the myofibrils and have a nucleus that reaches 4 μm in size. In gravid proglottids, the epithelium without nuclei is reduced to 0.2-1.6 μm thick. The number of protrusions of the uterine epithelium and lipid droplets in the epithelial layer decreases. Sparse small muscle bundles underlay the uterine wall at this stage; the basal matrix is feebly marked. The matrotrophy or the support by nutrition from the parent organism to embryos is discussed for T. erostris which belongs to oligolecital cestodes and possesses numerous lipid droplets in the uterine wall during the development of embryos.

Spinal extracellular signaling-regulated kinase 1 and 2 (ERK 1/2) have been found to contribute to nociceptive processing, but the role of spinal ERK 1/2 in visceral pain related to the uterine cervix, the source of pain during the first stage of labor, is unknown. The aim of this study was to investigate ERK activation (phosphorylation) in spinal dorsal horn neurons after acute uterine cervical distension. Under intraperitoneal anesthesia using chloral hydrate 300 mg/kg, female Sprague-Dawley rats were exposed to a 10-s uterine cervical distension of 25, 50, 75, and 100g or no distension (sham). The electromyographic response in the rectus abdominis muscle and mean arterial blood pressure and heart rate changes to uterine cervical distension were determined. The numbers of phosphorylated-ERK 1/2- immunoreactive (pERK 1/2-IR) dorsal horn neurons in cervical (C5-8), thoracic (T5-8), thoracolumbar (T12-L2) and lumbosacral (L(6)-S(1)) segments were counted using immunohistochemistry. Compared with the non-distended sham rats, uterine cervical distension resulted in a stimulus-dependent increase in electromyographic activity and the number of pERK-IR neurons that selectively located to the thoracolumbar segment, mostly in the deep dorsal and the central canal regions. The time course study demonstrated that spinal ERK activation peaked at 60 min with a slow decline for 120 min after uterine cervical distension stimulation. This study suggests that activation of spinal ERK might be involved in acute visceral pain arising from the uterine cervix. Copyright 2009 Elsevier Ltd. All rights reserved.

From 1983 to 1996 Phase II and III clinical studies at Henry Ford Hospital demonstrated complete or partial responses in 55 of 56 patients treated with hematoporphyrin-derivative or PHOTOFRIN-mediated photodynamic therapy (HPD-PDT) for a variety of benign and malignant upper aerodigestive tract disease: (1) superficial 'condemned mucosa' or 'field cancerization' of the oral cavity and larynx (7 cases); (2) Stage III/IV head and neck cancer (25 cases); (3) mucocutaneous AIDS-associated Kaposi's sarcoma of the upper aerodigestive tract and non AIDS-related Kaposi's sarcoma of the lower extremity (15 cases); (4) recurrent laryngotracheal papillomatosis (3 cases); (5) severe dysplasia/adenocarcinoma or squamous cell carcinoma in situ in Barrett's esophagus (4 cases); (6) partial or completely obstructing terminal esophageal cancer (9 cases). At the time of this report, HPD-PDT produced complete responses in 24 patients (follow up 6 months to 9 years) with 'field cancerization' (CIS, T1N0M0) of the oral cavity and larynx (6 cases), adenocarcinoma in situ in Barrett's esophagus (3 cases), mucocutaneous Kaposi's sarcoma (12 cases), obstructing esophageal carcinoma (1 case), and stage IV squamous cell carcinoma of the nasopharynx (1 case), and radiation therapy or solar-induced basal cell/squamous cell carcinomas (2 cases). PDT treatment protocols, results, complications, and application as adjunct or primary oncologic therapy for head and neck cancer are reviewed in this article.

Sarcomas are a heterogeneous group of rare tumors and arise either from soft tissue or from bone. Soft-tissue sarcomas (STSs) initially metastasize to the lungs. Metastases to extrapulmonary sites such as liver, brain, and soft tissue distant from primary tumor usually develop later. However, cases with isolated adrenal metastasis without disseminated disease have been reported in literature. We present a case of primary myxoid liposarcoma of the lower limb, in which staging 18 -F fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan detected a suspicious FDG avid adrenal lesion which eventually on resection was diagnosed as asymptomatic pheochromocytoma. Pheochromocytomas have been reported to demonstrate FDG uptake mimicking metastasis. Hence, while interpreting FDG PET-CT scans in the context of STSs, both the extrapulmonary metastatic potential of aggressive histological subtypes of sarcoma and rare possibility of FDG avid coexistent benign tumor should be taken into consideration.

During the period between Jan. 1 1992 and Dec. 31, 1995 at the Second Department of Gynaecology and Obstetrics in Brno labour was induced in 1159 patients by extraamnial fractionated administration of PGE2 vaginal tablets. After assessment of the indication and the baseline examination (NST, amnioscopy, US biometry and cervical score) according to the CS to the patient the first dose of PGE2 was administered into the extraamnial space beyond the inner os uteri (CS 5-8:1.0 mg PGE2, CS > 8 : 0.5 mg PGE2). After two hours the patient was examined again and if regular uterine contractions had started or the finding on the os uteri was larger than 2 cm, the amniotic sac was disrupted. If not, another dose was administered. After two hours the patient was re-examined and if the os was larger than 2 cm, and there were regular uterine contractions, the amniotic sac was disrupted. If the changes did not take place, the induction was considered a failure. there were 1007 successful inductions (95.5%), the mean period from the onset of induction to the onset of uterine contractions was < 120 mins-269 (24.6%), 120-180 mins.: 501 (45.9%) and > 180 mins.: 322 (29.5%). The mean period of the first stage of labour was 228 mins., stage II 10 mins., stage III 8 mins. Five times uterine hypertonus was recorded and a blood loss greater than 500 ml occurred in four patients. Forty-nine Caesarean sections were made (4.2%) and 51 (4.4%) forceps deliveries. The rate of epidural analgesia was 27 (2.3%). Revision of the uterine cavity was made in 39 patients (3.4%) and manual lysis of the placenta in 30 (2.6%). The Apgar score was inferior to 6 in 10 neonates (0.9%). The protocol of induction of labour described by the authors is effective and associated with a minimum of side-effects, safe for the mother and foetus, well tolerated by patients and cost-effective.

Evidence of potential prognostic and predictive value for nestin was investigated in well-annotated uterine cancers (UCs). Nestin expression and previously-published biomarkers were evaluated by immunohistochemistry (IHC) in UC tissue microarrays. Biomarkers were categorized as low vs. high, and nestin was cut at 10% positive staining. Relationship between nestin and clinicopathologic factors, biomarkers and outcome were evaluated using exact/log-rank testing or logistic/Cox modeling. There were 323 eligible cases, 34% had advanced stage disease, 37% had type II disease, and 5% were carcinosarcomas. High nestin, observed in 19% of cases, was more common in advanced vs. early stage disease, type II cancers or uterine carcinosarcoma vs. type I cancers, grade 3 disease, positive lymphovascular space invasion (LVSI) and tumors >6cm (p<0.05). Nestin was inversely correlated with ER, PR and TFF3, and correlated with p53 and IMP3. Women with high vs. low nestin had worse progression-free survival (PFS) and cancer-specific survival overall, and worse PFS in the subset who received no adjuvant therapy or radiation, or had early stage, type I disease or tumors with both low and high ER, PR, TFF3, PTEN, p53 or IMP3. The relationship between nestin and PFS was independent of stage, LVSI and risk categorization but not type of UC. High nestin was more common in UCs with aggressive features and poor outcome. Nestin may represent a predictive biomarker for treatment selection for patients previously considered to be lower risk and a candidate for no or radiation-based adjuvant therapy, and compliment ER/PR testing.

1993-05-01

Seventy-seven dogs with malignant tumors of the nasal and paranasal cavities were treated by use of radiotherapy. The tumors included carcinomas (58) and sarcomas (19). Radiographic findings, including site of involvement and tumor extension, were the basis of clinical staging. Staging was performed according to the tumor, node, metastasis staging of the World Health Organization, and a modified staging scheme based on prognostic factors that seemed to correlate best with response to treatment. All irradiations were done with a telecobalt 60 unit. Fifty-six dogs were treated with irradiation alone, and 21 had partial tumor resection prior to radiotherapy. Treatment dose was 48 Gy (minimal tumor dose) administered on a Monday-Wednesday-Friday basis at 4 Gy/fraction over 4 weeks. The irradiation technique emphasized rostral field with a generous treatment volume. Duration of follow-up after irradiation ranged from 1 month to 61 months. The 1- and 2-year overall survival rates were 60.3% and 25%, respectively, and the 1- and 2-year relapse-free survival rates were 38.2% and 17.6%, respectively. Results of histologic examination and our modified staging scheme were significant (P = 0.02 and P = 0.04, respectively) prognostic factors of relapse-free survival. Conversely, tumor site, tumor extension, World Health Organization clinical stage, and cytoreductive surgery prior to irradiation did not affect the outcome of treatment. According to our modified staging scheme, dogs with stage-2- disease have a poorer prognosis than dogs with stage-1 disease, with a relative risk of relapse 2.3-fold higher. Dogs with carcinoma had a poorer prognosis than dogs with sarcoma (predominantly chondrosarcoma) with a relative risk of relapse 3.3-fold higher.(ABSTRACT TRUNCATED AT 250 WORDS)

Uterine massage for preventing postpartum haemorrhage.

PubMed

Hofmeyr, G Justus; Abdel-Aleem, Hany; Abdel-Aleem, Mahmoud A

2013-07-01

Postpartum haemorrhage (PPH) (bleeding from the genital tract after childbirth) is a major cause of maternal mortality and disability, particularly in under-resourced areas. In these settings, uterotonics are often not accessible. There is a need for simple, inexpensive techniques which can be applied in low-resourced settings to prevent and treat PPH. Uterine massage is recommended as part of the routine active management of the third stage of labour. However, it is not known whether it is effective. If shown to be effective, uterine massage would represent a simple intervention with the potential to have a major effect on PPH and maternal mortality in under-resourced settings. To determine the effectiveness of uterine massage after birth and before or after delivery of the placenta, or both, to reduce postpartum blood loss and associated morbidity and mortality. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013). All published, unpublished and ongoing randomised controlled trials comparing uterine massage alone or in addition to uterotonics before or after delivery of the placenta, or both, with non-massage. Two researchers independently considered trials for eligibility, assessed risk of bias and extracted the data using the agreed form. Data were checked for accuracy. The effect of uterine massage commenced before or after placental delivery were first assessed separately, and then the combined for an overall result. This review included two randomised controlled trials. The first trial included 200 women who were randomised to receive uterine massage or no massage following delivery of the placenta, after active management of the third stage of labour including use of oxytocin. The numbers of women with blood loss more than 500 mL was small, with no statistically significant difference (risk ratio (RR) 0.52, 95% confidence interval (CI) 0.16 to 1.67). There were no cases of retained placenta in either group. The mean blood loss was significantly less in the uterine massage group at 30 minutes (mean difference (MD) -41.60 mL, 95% CI -75.16 to -8.04) and 60 minutes after trial entry (MD -77.40 mL, 95% CI -118.71 to -36.09). The need for additional uterotonics was significantly reduced in the uterine massage group (RR 0.20, 95% CI 0.08 to 0.50).For use of uterine massage before and after delivery of the placenta, one trial recruited 1964 women in Egypt and South Africa. Women were assigned to receive oxytocin, uterine massage or both after delivery of the baby but before delivery of the placenta. There was no added benefit for uterine massage plus oxytocin over oxytocin alone as regards blood loss greater than or equal to 500 mL (average RR 1.56, 95% CI 0.44, 5.49; random-effects) or need for additional use of uterotonics (RR 1.02, 95% CI 0.56 to 1.85).The two trials were combined to examine the effect of uterine massage commenced either before or after delivery of the placenta. There was substantial heterogeneity with respect to the blood loss 500 mL or more after trial entry. The average effect using a random-effects model found no statistically significant differences between groups (average RR 1.14, 95% CI 0.39 to 3.32; random-effects). The results of this review are inconclusive, and should not be interpreted as a reason to change current practice. Due to the limitations of the included trials, more trials with sufficient numbers of women are needed in order to estimate the effects of sustained uterine massage. All the women compared in this review received oxytocin as part of the active management of labour. Recent research suggests that once an oxytocic has been given, there is limited scope for further reduction in postpartum blood loss. Trials of uterine massage in settings where uterotonics are not available, and which measure women's experience of the procedure, are needed.

To document uterine growth and microvascular development in the endometrium of uteri with differing degrees of fibrosis as well as uterine growth throughout the estrous cycle of mares. 30 mares. Uterine tissue was obtained during the breeding season from a slaughter facility. Stage of estrous cycle of the mares was assessed on the basis of ovarian structures and plasma progesterone concentrations. Endometrium was characterized by use of light microscopy, and blood vessel walls were marked by histochemical techniques. Microvascular development was evaluated by a computerized image analysis system. Growth of uterine tissue was based on cellular content of DNA and RNA, RNA:DNA, and protein:DNA. Significant differences in vascular density were not observed in the endometrium of uteri obtained from mares euthanatized during the follicular or luteal phase of the estrous cycle, regardless of whether endometrial classification of degree of fibrosis was considered. There was a 3-fold increase in amount of DNA and RNA of endometrial cells in the follicular phase when compared to myometrium. Hypertrophy of endometrial tissue during the luteal phase was reflected by a significant increase in cell protein content and protein:DNA. Endometrial growth of vascular tissues during the estrous cycle may be coordinated with development of nonvascular tissue. Estrogen and progesterone may play a role in regulation of uterine growth and angiogenesis.

Canine Soft Tissue Sarcomas: Can Being a Dog’s Best Friend Help a Child?

PubMed Central

Séguin, Bernard

2017-01-01

Soft tissue sarcomas (STSs) remain a therapeutic challenge for pediatric and adolescent and young adult (AYA) patients. Still today, surgery, radiation therapy, and chemotherapy remain the mainstay of treatment. Obstacles in developing new treatment approaches to improve the outcome are: few patients to enroll in clinical trials, and the diversity of tumor biology between histologic subtypes. Pet dogs may offer an additional strategy to discover and test new therapeutic avenues. The number of dogs diagnosed with a STS each year in the United States is estimated to be around 27,000 to 95,000. In comparison, approximately 900 children less than 20 years old and 1,500 AYAs between 15 and 29 years old are diagnosed with a STS each year in the United States. The mainstay for treatment of STSs in dogs is also surgery, with radiation therapy and chemotherapy when necessary. Similar to what is seen in humans, grade and stage are prognostic in dogs. In one comparative study of the histology and immunohistochemistry of canine STSs, most tumors were diagnosed as the human equivalent of undifferentiated sarcoma, spindle cell sarcoma, or unclassified spindle cell sarcoma. But much work remains to be done to fully assess the validity of canine STSs as a model. Gene expression analysis has been done in a limited number of canine STSs. Tissue banking, development of cell lines, and the ability to mobilize large-scale clinical trials will become essential in veterinary medicine to benefit both dogs and humans. PMID:29218302

Extrinsic Factors Influencing Fetal Deformations and Intrauterine Growth Restriction

Moh, Wendy; Graham, John M.; Wadhawan, Isha; Sanchez-Lara, Pedro A.

2012-01-01

The causes of intrauterine growth restriction (IUGR) are multifactorial with both intrinsic and extrinsic influences. While many studies focus on the intrinsic pathological causes, the possible long-term consequences resulting from extrinsic intrauterine physiological constraints merit additional consideration and further investigation. Infants with IUGR can exhibit early symmetric or late asymmetric growth abnormality patterns depending on the fetal stage of development, of which the latter is most common occurring in 70–80% of growth-restricted infants. Deformation is the consequence of extrinsic biomechanical factors interfering with normal growth, functioning, or positioning of the fetus in utero, typically arising during late gestation. Biomechanical forces play a critical role in the normal morphogenesis of most tissues. The magnitude and direction of force impact the form of the developing fetus, with a specific tissue response depending on its pliability and stage of development. Major uterine constraining factors include primigravida, small maternal size, uterine malformation, uterine fibromata, early pelvic engagement of the fetal head, aberrant fetal position, oligohydramnios, and multifetal gestation. Corrective mechanical forces similar to those that gave rise to the deformation to reshape the deformed structures are often used and should take advantage of the rapid postnatal growth to correct form.

The aim of this work is to study early embryo survival and development in 2 lines divergently selected for high and low uterine capacity throughout 10 generations. A total of 162 female rabbits from the high line and 133 from the low line were slaughtered at 25, 48, or 62 h of gestation. There were no differences in ovulation rate and fertilization rate between lines in any of the 3 stages of gestation. Embryo survival, estimated as the number of normal embryos recovered at a constant ovulation rate, was similar in both lines at 25 and 48 h. Embryo survival was greater in the high line [D (posterior mean of the difference between the high and low lines) = 0.57 embryos] at 62 h of gestation. There was no difference in embryonic stage of development at 25 h, but at 48 and 62 h of gestation, the high line, compared with the low line, had a greater percentage of early morulae (83 vs. 72%) and compacted morulae (55 vs. 38%). Divergent selection for uterine capacity appeared to modify embryo development, at least from 48 h of gestation, and embryo survival from 62 h.

To determine the effect of uterine fundal pressure on shortening the second stage of labor and on the fetal outcome. Randomized controlled trial. Teaching and research hospital. One hundred ninety-seven women between 37 and 42 gestational weeks with singleton cephalic presentation admitted to the delivery unit. Random allocation into groups with or without manual fundal pressure during the second stage of labor. The primary outcome measure was the duration of the second stage of labor. Secondary outcome measures were umbilical artery pH, HCO3-, base excess, pO2, pCO2 values and the rate of instrumental delivery, severe maternal morbidity/mortality, neonatal trauma, admission to neonatal intensive care unit, and neonatal death. There were no significant differences in the mean duration of the second stage of labor and secondary outcome measures except for mean pO2 which was lower and mean pCO2 which was higher in the fundal pressure group. Nevertheless, the values still remained within normal ranges and there were no neonates with an Apgar score <7 in either of the groups. Application of fundal pressure on a delivering woman was ineffective in shortening the second stage of labor.

Osteopontin (OPN) overexpression is correlated with a poor prognosis for tumor patients. However, only a few studies investigated the prognostic impact of expression of OPN in soft tissue sarcomas (STS) yet. This study is based on tumor and serum samples from 93 adult STS patients. We investigated OPN protein levels in serum (n = 86) and tumor tissue (n = 80) by ELISA and OPN mRNA levels in tumor tissue (n = 68) by quantitative real-time PCR. No correlation was found between OPN levels in serum and tumor tissue. Moreover, an elevated OPN protein level in the serum was significantly associated with clinical parameters such as higher stage (p = 0.004), higher grade (p = 0.003), subtype (p = 0.002) and larger tumor size (p = 0.03). OPN protein levels in the tumor tissue were associated with higher stage (p = 0.06), higher grade (p = 0.003), subtype (p = 0.07) and an increased rate of relapse (p = 0.02). In addition, using a Cox's proportional hazards regression model, we found that an elevated OPN protein level in the serum and tumor tissue extracts is a significant negative prognostic factor for patients with STS. The relative risks of tumor-related death were 2.2 (p < 0.05) and 3.7 (p = 0.01), respectively. Our data suggest OPN protein in serum as well as in tumor tissue extracts is an important prognostic factor for soft tissue sarcoma patients.

Stromal cell-derived factor-1 (SDF-1) predicts poor clinical outcomes of certain types of cancer. Furthermore, vascular endothelial growth factor (VEGF) promotes the growth and metastasis of solid tumors. The aim of the present study was to examine the expression of SDF-1 and VEGF in patients with synovial sarcoma and to determine their expression is correlated with unfavorable outcomes. Levels of SDF-1 and VEGF proteins were evaluated in 54 patients with synovial sarcoma using immunohistochemical and immunofluorescence staining. Potential associations between the expression of SDF-1 and VEGF and various clinical parameters were analyzed using Pearson's χ 2 test and the Spearman-rho test. Additionally, univariate and multivariate Cox regression analyses were used to identify potential prognostic factors, and the Kaplan-Meier method was used to analyze the overall survival rates of patients. Low SDF-1 and VEGF expression was detected in 20.4% (11/54) and 22.2% (12/54) of patients with synovial sarcoma; moderate expression was detected in 35.2% (19/54) and 37.0% (20/54) of patients and high expression was detected in 44.4% (24 of 54) and 40.7% (22 of 54) of patients, respectively. Levels of SDF-1 and VEGF proteins were significantly associated with histological grade (P<0.05), metastasis (P<0.05) and American Joint Committee on Cancer staging (P<0.05). In addition, levels of SDF-1 and VEGF expression were positively correlated with each other (P<0.001). Univariate analysis also indicated that VEGF expression was associated with shorter overall survival rates in (P<0.05), whereas multivariate analysis demonstrated that SDF-1 expression was associated with shorter patient survival rates (P<0.05). Finally, both SDF-1 and VEGF expression were associated with various characteristics of synovial sarcoma. Therefore, SDF-1 expression may be a potential independent prognostic indicator in patients with synovial sarcomas.

Optimal management of early-stage uterine papillary serous carcinoma (UPSC) remains controversial. We reviewed our outcomes in this patient population. The Roswell Park Cancer Institute (RPCI) tumor registry identified all patients with Stages I and IIA UPSC treated between January 1992 and June 2006. The Fisher's exact test was used to compare recurrence rates by adjuvant therapy received. Overall survival (OS) estimates were made using the Kaplan-Meier method. Fifty-eight patients with Stage I or IIA UPSC underwent surgery. Thirty-four patients (59%) were surgically staged. Among 21 patients with Stage IA disease, 15 received adjuvant therapy. With a median follow-up of 44.7 months, only one recurrence was observed in a patient who received adjuvant brachytherapy. The 5-year OS was 66%. Among 37 patients with Stages IB-IIA, 30 patients received adjuvant therapy. With a median follow-up of 29 months, there were 7 recurrences. The 5-year OS was 60%. Although there were no significant differences in recurrence by adjuvant therapy received, a significant OS benefit was found in those who received radiation. There was no significant difference in OS distributions of those patients who received Carboplatin/Paclitaxel chemotherapy. Despite the limitations of our retrospective study, we have shown that even comprehensively staged early-stage UPSC patients are still at risk for recurrence despite adjuvant therapy received. Hence, all patients with this histologic diagnosis should be considered at high risk for recurrence and counseled appropriately regarding the risks and benefits of adjuvant therapy.

Patient: Female, 61 Final Diagnosis: Uterine PEComa with ovarian involvement Symptoms: Palpable abdominal mass Medication: — Clinical Procedure: Hysterectomy and bilateral salpingo-oophorectomy Specialty: Obstetrics and Gynecology Objective: Rare disease Background: Perivascular epithelioid cell tumors (PEComas) are a rare group of neoplasms composed of epithelioid cells that express both melanocytic and myoid markers. When considering PEComas of the female genital tract, the uterus is the most common location. Involvement of the ovary in the context of a primary uterine PEComa, in the absence of systemic disease associated with tuberous sclerosis, however, has only been reported in 1 previous case. Case Report: We report a case of a PEComa of the uterus with metastasis to the left ovary in a 61-year-old Caucasian woman. Gross examination of the uterus revealed a 10.7×10.5×10.2 cm tan-brown, mostly solid, partially cystic mass. Microscopic examination showed epithelioid cells with clear to eosinophilic cytoplasm, arranged in fascicles. Intranuclear pseudoinclusions were also noted. The tumor cells were smooth muscle actin, caldesmon, and desmin positive (diffuse); HMB-45 positive (focal); and Melan-A, AE1/AE3, CD10, and S100 negative by immunohistochemistry. Conclusions: Distinguishing among mesenchymal neoplasms, including PEComas, endometrial stromal sarcomas, and leiomyosarcomas, can be difficult. Careful analysis of morphologic and immunohistochemical features is of the utmost importance. Differential diagnosis, including morphologic features and immunohistochemical patterns, is also discussed. PMID:27150246

Histology, grade, tumor size, stage, and treatment modality were analyzed. Overall survival was assessed. Five patients had rhabdomyosarcoma (RMS) and five had other subtypes, including two with carcinosarcoma, two with high-grade sarcoma not-otherwise-specified, and one with leiyomyosarcoma. Eight patients presented with locally advanced disease and two with metastatic disease.The two metastatic patients received chemotherapy, and one also had hormonal ablation therapy. Of the eight with local disease, two had neoadjuvant chemotherapy and surgery, one had surgery alone, one had surgery and postoperative radiation, one had radiation alone, and three had chemoradiation.Chemotherapy consisted of vincristine, adriamycin, and cyclophosphomide for rhabdomyosarcoma and of cisplatin, adriamycin, and ifosphamide for the other subtypes. Radiation dose ranged from 40 Gy to 55.8 Gy.The median survival follow-up of the study is 46.5 months. The median survival for the rhabdomyosarcoma subgroup and nonrhabdomyosarcoma subroup is 142 months and 24 months, respectively. There were three deaths, of which two had metastatic disease at presentation and one later developed distant metastases after having surgery alone. One patient developed a local recurrence 47 months after chemoradiation and was successfully salvaged with surgery. In terms of tumor-related factors, the histologic subtype of prostate sarcoma appears to have prognostic significance. The overall survival for adults with non-RMS histologies is poor with a median survival of only 2 years. Pediatric patients with RMS faired much better with a median survival of over 10 years. We did not find any difference in outcome with regard to grade or tumor size. The presence of metastatic disease at diagnosis, however, is a poor predictor of outcome.In terms of treatment-related factors, surgery alone is inadequate treatment. One patient treated with surgery alone developed distant metastases 38 months later, then received chemotherapy and hormonal therapy, and died at 58 months. Patients who received combined modality treatment appear to fare better.Finally, these patients need long term follow-up. One patient developed a local recurrence 47 months after chemoradiation. This patient was successfully salvaged with surgery and is currently alive at 170 months.

Kaposi sarcoma (KS) has features of both neoplastic growth and hyperplastic proliferation. It is the most common tumor seen in patients with HIV infection. Whether KS is a real tumor or a benign hyperplastic disease is not known. Tissues from KS and cutaneous hemangioma lesion DNA were extracted, and then digested with methylation-sensitive restriction endonuclease HpaII. Human androgen receptor gene (HUMARA) was amplified with PCR method and the product was separated on 10% denaturing polyacrylamide gels and stained with ethylene dibromide (EB) to show the polymorphism of HUMARA. Phosphoglycerate kinase (PGK) was amplified and the product was digested by BStXI, agarose gel and EB stained to show the polymorphism of PGK. Finally, we analyzed the clonality of KS. In the 14 patients with KS, heterozygosity of the HUMARA gene was observed in 12 (85.7%) cases. Loss of heterozygosity of HUMARA gene on X-chromosome (without HpaII digestion there were 2 bands, after HpaII digestion there were just 1 of the bands), representing monoclonal origin, was present in 11 cases of Kaposi sarcoma. Heterozygosity of the PGK gene was observed in 5 (35.7%) cases, which all represent monoclonal origin. There was no significant difference according to country, stage, or HIV and HHV-8 (P>0.05). The current findings suggest that Kaposi sarcoma is a clonal neoplasm, not a reactive proliferation.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS). KSHV infection induces and requires multiple metabolic pathways, including the glycolysis, glutaminolysis, and fatty acid synthesis (FAS) pathways, for the survival of latently infected endothelial cells. To determine the metabolic requirements for productive KSHV infection, we induced lytic replication in the presence of inhibitors of different metabolic pathways. We found that glycolysis, glutaminolysis, and FAS are all required for maximal KSHV virus production and that these pathways appear to participate in virus production at different stages of the viral life cycle. Glycolysis and glutaminolysis, but not FAS, inhibit viral genome replication and, interestingly, are required for different early steps of lytic gene expression. Glycolysis is necessary for early gene transcription, while glutaminolysis is necessary for early gene translation but not transcription. Inhibition of FAS resulted in decreased production of extracellular virions but did not reduce intracellular genome levels or block intracellular virion production. However, in the presence of FAS inhibitors, the intracellular virions are noninfectious, indicating that FAS is required for virion assembly or maturation. KS tumors support both latent and lytic KSHV replication. Previous work has shown that multiple cellular metabolic pathways are required for latency, and we now show that these metabolic pathways are required for efficient lytic replication, providing novel therapeutic avenues for KS tumors. IMPORTANCE KSHV is the etiologic agent of Kaposi's sarcoma, the most common tumor of AIDS patients. KS spindle cells, the main tumor cells, all contain KSHV, mostly in the latent state, during which there is limited viral gene expression. However, a percentage of spindle cells support lytic replication and production of virus and these cells are thought to contribute to overall tumor formation. Our previous findings showed that latently infected cells are sensitive to inhibitors of cellular metabolic pathways, including glycolysis, glutaminolysis, and fatty acid synthesis. Here we found that these same inhibitors block the production of infectious virus from lytically infected cells, each at a different stage of viral replication. Therefore, inhibition of specific cellular metabolic pathways can both eliminate latently infected cells and block lytic replication, thereby inhibiting infection of new cells. Inhibition of metabolic pathways provides novel therapeutic approaches for KS tumors. Copyright © 2017 American Society for Microbiology.

Primitive neuroectodermal tumor of the cervix: a case report

PubMed Central

2011-01-01

Introduction Peripheral primitive neuroectodermal tumor of the cervix uteri is extremely rare. Between 1987 and 2010, there were only nine cases reported in the English literature, with considerably different management policies. Case presentation A 45-year-old Iranian woman presented to our facility with a primitive neuroectodermal tumor of the cervix uteri. Her clinical stage IB2 tumor was treated successfully with chemotherapy. Our patient underwent radical hysterectomy. There was no trace of the tumor after four years of follow-up. Conclusions According to current knowledge, primitive neuroectodermal tumors belong to the Ewing's sarcoma family, and the improvement of treatment outcome in our patient was due to dose-intensive neoadjuvant chemotherapy, surgery and consolidation chemotherapy in accordance with the protocol for bony Ewing's sarcoma.

(1) To compare the anatomopathological variables and recurrence rates in patients with early-stage adenocarcinoma (AC) and squamous cell carcinoma (SCC) of the uterine cervix; (2) to identify the independent risk factors for recurrence. This historical cohort study assessed 238 patients with carcinoma of the uterine cervix (IB and IIA), who underwent radical hysterectomy with pelvic lymph node dissection between 1980 and 1999. Comparison of category variables between the two histological types was carried out using the Pearson's chi(2)-test or Fisher exact test. Disease-free survival rates for AC and SCC were calculated using the Kaplan-Meier method and the curves were compared using the log-rank test. The Cox proportional hazards model was used to identify the independent risk factors for recurrence. There were 35 cases of AC (14.7%) and 203 of SCC (85.3%). AC presented lower histological grade than did SCC (grade 1: 68.6% versus 9.4%; p<0.001), lower rate of lymphovascular space involvement (25.7% versus 53.7%; p=0.002), lower rate of invasion into the middle or deep thirds of the uterine cervix (40.0% versus 80.8%; p<0.001) and lower rate of lymph node metastasis (2.9% versus 16.3%; p=0.036). Although the recurrence rate was lower for AC than for SCC (11.4% versus 15.8%), this difference was not statistically significant (p=0.509). Multivariate analysis identified three independent risk factors for recurrence: presence of metastases in the pelvic lymph nodes, invasion of the deep third of the uterine cervix and absence of or slight inflammatory reaction in the cervix. When these variables were adjusted for the histological type and radiotherapy status, they remained in the model as independent risk factors. The AC group showed less aggressive histological behavior than did the SCC group, but no difference in the disease-free survival rates was noted.

Intradural extramedullary Ewing's sarcoma: A case report and review of the literature.

Extra-skeletal Ewing's sarcomas are very rare lesions to the spine surgeon, with the intradural, extramedullary lesions being even rarer. Herein we present a patient with an intradural, extramedullary form of Ewing's sarcoma and review the relevant literature. The medical records, operative reports, radiographical studies and histological examinations of a single patient are retrospectively reviewed. A 31-year old male presented with back-pain, right-leg progressive paraparesis, and inability to walk. Both motor and sensory disturbances were revealed on the right leg at the clinical examination. Lumbar MRI showed two lesions. The first one was an intradural, extramedullary lesion at the L2-L3 level, while the second was smaller, located at the bottom of the dural sac. The patient underwent gross total resection of the L2-L3 lesion after a bilateral laminectomy. Histological examination was compatible with Ewing's sarcoma, and was verified by molecular analysis. No other extra-skeletal or skeletal lesion was found. A chemotherapy scheme was tailored to the patients' histological diagnosis. The patient presented with local recurrence and bone metastasis 2 years after his initial diagnosis. A second operation was performed and the follow up of the patient showed no disease progression 18 months after revision surgery. The spine surgeon should be aware of the existence of such rare entities, in order to timely fulfill the staging process and institute the proper therapy. The management of patients with extra-skeletal Ewing's sarcomas involves professionals as members of a multidisciplinary team, all of which should co-operate for the patient's optimal outcome.

The objectives were to: (1) describe the chronology of early embryonic development from ovulation to entry into the uterus; and (2) to determine the timing of embryo migration to the left uterine horn when ovulation occurred from the right ovary. The experiment was conducted in Peru. Females (n = 132) were randomly assigned to 15 experimental groups. All females were mated to an intact male, given 50 μg GnRH im (Cystorelin) and ovulation time determined by transrectal ultrasonography, conducted every 6 hours, starting 24 hours postmating. Animals were slaughtered at a specific intervals postovulation and reproductive tracts were recovered and subjected to oviductal and uterine flushing for females slaughtered between 1 and 6 days postovulation (dpo; Day 0 = ovulation) and uterine flushing for females slaughtered from 7 to 15 dpo for recovery of oocytes/embryos. Season of mating did not influence the interval from mating to ovulation (winter: 29 ± 6 hours vs. summer: 30 ± 6 hours; P = 0.49). Ovulation rates for females mated during winter and summer were 92% versus 100%, respectively (P = 0.05). Fertilization rates for winter and summer mated females were 72% and 82% (P = 0.29). Unfertilized ova were not retained in the uterine tube. All embryos collected were in the uterine tube ipsilateral to the side of ovulation between 1 and 5 dpo. Embryos reached the uterus on 6 dpo. Embryos began to elongate on 9 dpo; at this time, 83% of embryos derived from right-ovary ovulations were collected from the left uterine horn. Embryos occupied the entire uterine cavity by 10 dpo. In conclusion, we characterized early embryo development and location of embryo during its early developmental stages in alpaca. This was apparently the first report regarding chronology of embryo development and migration to the left horn in alpaca which merits further investigation regarding its role in maternal recognition of pregnancy.

Uterine blood flow in sows: effects of pregnancy stage and litter size.

PubMed

Père, M C; Etienne, M

2000-01-01

Female pigs were assigned to three groups at 94 days of age: a control group (CTR), a group undergoing the ligation and severing of the left oviduct (LIG), and a group undergoing right hysteroovariectomy (HHO). They were inseminated at 307 days of age. At 35 days of pregnancy, an ultrasonic transit time flow probe was implanted around the middle artery of one uterine horn in 33 sows and uterine blood flow was measured during thirteen 24-h periods between 44 and 111 days. Despite large differences in ovulation rate per uterine horn (4.8, 8.3 and 16.9 in the LIG, CTR and HHO groups, respectively), variation of litter size was considerably reduced with advancement of pregnancy (3.0, 6.6 and 10.8 foetuses per uterine horn at 35 days, and 3.0, 5.8 and 4.9 at 112 days (slaughter), respectively). Uterine blood flow increased linearly during pregnancy. It was lower in the LIG sows (0.82 to 1.74 L x min(-1) x horn(-1) from 44 to 111 days) than in the CTR and HHO sows (1.22 to 2.84 and 1.09 to 2.63 L x min(-1) x horn(1), respectively). It was more closely related to litter weight than to litter size and amounted to 0.42 L x min(-1) x kg foetus(-1) at 111 days. Uterine blood flow per foetus decreased when litter size increased. It increased from 0.31 to 0.72, 0.26 to 0.60 and 0.20 to 0.43 L x min(-1) x foetus(-1) from 44 to 111 days when there were 2 to 3, 4 to 5, and 6 to 8 foetuses in the uterine horn, respectively. This explains why piglets from large litters are lighter at birth.

Detection of comorbidities and synchronous primary tumours via thoracic radiography and abdominal ultrasonography and their influence on treatment outcome in dogs with soft tissue sarcomas, primary brain tumours and intranasal tumours.

Canine soft tissue sarcomas (STS), primary brain tumours and intranasal tumours are commonly treated with radiotherapy (RT). Given the low metastatic potential of these tumours, recommendations regarding imaging tests as staging are variable among institutions. The purpose of our study was to describe thoracic radiographic and abdominal ultrasonographic findings in dogs with these neoplasms and to investigate association of abnormal findings with alterations in recommended treatment. Medical records from 101 dogs, each having thoracic radiographs and abdominal ultrasound performed as part of their staging, were reviewed. In 98 of 101 (97%), imaging abnormalities were detected, 27% of which were further investigated with fine needle aspiration cytology or biopsy. Nine percent of the detected abnormalities were considered serious comorbidities that altered treatment recommendations, including 3 (3%) which were confirmed as synchronous primary neoplasms. These findings may influence recommendations regarding the decision to perform thoracic radiographs and abdominal ultrasound prior to initiation of RT. © 2013 John Wiley & Sons Ltd.

Serous endometrial intraepithelial carcinoma: a case series and literature review.

PubMed

Pathiraja, P; Dhar, S; Haldar, K

2013-01-01

Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients.

To evaluate biological differences among young subjects with premature ovarian insufficiency (POI) commencing at different stages of life. Retrospective observational study. Careggi University Hospital Participants: One hundred sixty-two females aged between 15 and 29 years with premature ovarian insufficiency. Data were collected as a retrospective chart review of baseline evaluation at diagnosis of premature ovarian insufficiency (POI). About 162 participants were divided into four groups based on gynecological age. Two primary outcome variables (uterine development and bone mineral density (BMD)) were analyzed in terms of differences among groups and in a multivariate logistic regression analysis. Uterine development was clearly jeopardized when estrogen insufficiency started at a very young age. Total body BMD showed significant differences among the four groups studied, clearly corresponding to the duration of ovarian function. Data were discussed in relation to the choice of hormone replacement therapy regimens.

Metastases to the breast from extramammary malignancies are infrequent, the most common primary sites are malignant melanoma, leukemia, lymphoma, and cancer of the lung, stomach, prostate and ovary. The cervical origin is exceptional. Splenic metastasis from squamous cell carcinoma of the cervix is also rare. To the best of our knowledge, only three cases of isolated splenic metastasis have been reported in the literature. We describe the case of a 55-year-old North African woman who presented with a nodule in her left breast eight months after treatment for stage IIB squamous cell uterine cervical carcinoma. The excisional biopsy with histological study demonstrated a poorly differentiated squamous cell carcinoma. A computed tomography scan revealed a splenic secondary location. We report here a case of two unusual metastatic sites of uterine cervical carcinoma, the breast and spleen. It is the first case of this association without widespread disease.

Whether BRCA1 and BRCA2 mutation carriers have a clinically relevant elevated risk of uterine cancer has implications for risk-reducing surgery. This multicentre, prospective cohort study assessed uterine cancer risk for mutation carriers compared with the general population. Eligible mutation carriers were enrolled in the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer (kConFab) cohort study, had a uterus present and no history of uterine cancer at cohort entry. Epidemiological, lifestyle and clinical data were collected at cohort entry and updated three-yearly. Cancer events were verified using pathology reports. Follow-up was censored at death or last contact. Relative risk of uterine cancer was estimated using the standardised incidence ratio (SIR), with the expected number of cases determined using population-based data for Australia. Of 1,111 mutation carriers in kConFab, 283 were excluded due to prior hysterectomy (N = 278), prior uterine cancer (N = 2) or being non-residents (N = 3). After a median follow-up of 9.0 years, five incident uterine cancers were reported in the 828 eligible women (419 had prior breast cancer and 160 had prior tamoxifen use), compared to 2.04 expected (SIR = 2.45; 95% confidence interval [CI]: 0.80-5.72; P = 0.11). In 438 BRCA1 mutation carriers and 390 BRCA2 mutation carriers, three and two incident cases of uterine cancer were reported, respectively, compared to 1.04 expected (SIR = 2.87; 95% CI: 0.59-8.43; P = 0.18) and 0.99 expected (SIR = 2.01; 95% CI: 0.24-7.30; P = 0.52), respectively. All cases were endometrioid subtype, International Federation of Gynaecology and Obstetrics stage I-II disease. No serous uterine cancers were reported. Our findings are consistent with those from most other reports and do not support routine risk-reducing hysterectomy for BRCA1 and BRCA2 mutation carriers. Copyright © 2017 Elsevier Ltd.

Purpose: To provide further understanding regarding outcome and prognostic factors of endometrial stromal tumors (EST). Methods and Materials: A retrospective analysis was performed on the records of 59 women diagnosed with EST and treated with curative intent between 1983 and 2007 in the framework of the Rare Cancer Network. Results: Endometrial stromal sarcomas (ESS) were found in 44% and undifferentiated ESS (UES) in 49% of the cases. In 7% the grading was unclear. Of the total number of patients, 33 had Stage I, 4 Stage II, 20 Stage III, and 1 presented with Stage IVB disease. Adjuvant chemotherapy was administeredmore » to 12 patients, all with UES. External-beam radiotherapy (RT) was administered postoperatively to 48 women. The median follow-up was 41.4 months. The 5-year overall survival (OS) rate was 96.2% and 64.8% for ESS and UES, respectively, with a corresponding 5-year disease-free survival (DFS) rate of 49.4% and 43.4%, respectively. On multivariate analysis, adjuvant RT was an independent prognostic factor for OS (p = 0.007) and DFS (p = 0.013). Locoregional control, DFS, and OS were significantly associated with age ({<=}60 vs. >60 years), grade (ESS vs. UES), and International Federation of Gynecology and Obstetrics stage (I-II vs. III-IV). Positive lymph node staging had an impact on OS (p < 0.001). Conclusion: The prognosis of ESS differed from that of UES. Endometrial stromal sarcomas had an excellent 5-year OS, whereas the OS in UES was rather low. However, half of ESS patients had a relapse. For this reason, adjuvant treatment such as RT should be considered even in low-grade tumors. Multicenter randomized studies are still warranted to establish clear guidelines.« less

Magnetic resonance imaging findings and prognosis of gastric-type mucinous adenocarcinoma (minimal deviation adenocarcinoma or adenoma malignum) of the uterine corpus: Two case reports.

Our group previously documented the first, very rare case of primary gastric-type mucinous adenocarcinoma of the uterine corpus. Although this type of endometrial cancer appears to be similar to the gastric-type adenocarcinoma of the uterine cervix, its main symptoms, appearance on magnetic resonance imaging (MRI) and prognosis have not been fully elucidated due to its rarity. We herein describe an additional case of gastric-type mucinous adenocarcinoma of the endometrium and review the relevant literature. The two cases at our institution (Kyoto University Hospital, Kyoto, Japan) involved postmenopausal women with a primary complaint of abnormal genital bleeding. Microscopic examination of the hysterectomy specimens indicated a highly differentiated mucinous adenocarcinoma with a desmoplastic stromal reaction. Immunohistochemistry for HIK1083 and/or MUC6 was positive in both cases, suggesting a gastric phenotype. Both patients were diagnosed at an advanced stage, they relapsed or recurred immediately after adjuvant chemotherapy, and eventually succumbed to the disease. The main symptom of gastric-type mucinous adenocarcinoma of the uterine cervix is watery discharge, whereas abnormal genital bleeding in addition to watery discharge is mainly observed in the mucinous type of endometrial adenocarcinoma. Cystic cavities in the tumor are present on MRI in cases of endometrial origin, and prognosis is very poor due to resistance to chemotherapy. Thus, gastric-type mucinous adenocarcinoma of the uterine endometrium exhibits a clinical behavior that is similar to tumors originating from the uterine cervix, but is associated with distinguishing clinical symptoms. The incidence of gastric-type endometrial adenocarcinoma may be higher than expected.

In the case of carcinogenesis in human endometrium no information exists on tissue concentration of 8-oxo-7,8-dihydroguanine, the DNA oxidative stress marker This was the main reason to undertake the investigation of this DNA modification in human uterine estrogen-dependent tissue cancers. In order to estimate the level of oxidative damage, 8-oxo-7,8-dihydroguanine was determined directly in cells of tissue microscope slides using OxyDNA Assay Kit, Fluorometric. Cells were investigated under confocal microscope. Images of individual cells were captured by computer-interfaced digital photography and analyzed for fluorescence intensities (continuous inverted 8-bit gray-scale = 0 [black]-255 [white]). Fluorescence scores were calculated for each of 13 normal endometrial samples and 31 uterine adenocarcinoma specimens. Finally the level of the oxidative stress marker was also analyzed according to histological and clinical features of the neoplasms. The obtained data revealed that: 8-oxo-7,8-dihydroguanine levels were higher in uterine adenocarcinomas than in normal endometrial samples (48,32 vs. 38,64; p<0,001); in contrast to normal endometrium there was no correlation between age and DNA oxidative modification content in uterine cancer; highest mean fluorescence intensity was recognized in G2 endometrial adenocarcinomas; level of 8-oxo-7,8-dihydroguanine does not depend on Body Mass Index (BMI) and cancer uterine wall infiltration or tumor FIGO stage. Our study indicates that accumulation of the oxidized DNA base may contribute to the development of endometrial neoplasia, however oxidative DNA damage does not seem to increase with tumor progression.

Maternal obesity is associated with prolonged and dysfunctional labour and emergency caesarean section, but the mechanisms are unknown. The present study investigated the effects of an adiposity-inducing high-fat, high-cholesterol (HFHC) diet on uterine contractile-associated protein (CAP) expression and ex vivo uterine contractility in term non-labouring (TNL) and term labouring (TL) rats. Female rats were fed either control chow (CON n=20) or HFHC (n=20) diet 6 weeks before conception and during pregnancy. On gestational day 21 (TNL) or day 22 (TL) CON and HFHC (n=10) rats were killed to determine plasma cholesterol, triacylglycerol and progesterone concentrations and collection of myometrium for contractility studies and expression of CAPs caveolin-1 (Cav-1), connexin-43 (CX-43) and it's phosphorylated form (pCX-43), oxytocin receptor (OXTR) and cyclooxygenase-2 (COX-2). HFHC feeding increased visceral fat (P≤0.001), plasma cholesterol (P≤0.001) and triacylglycerol (P=0.039) concentrations. Stage of labour effected uterine expression of CAV-1 (P<0.02), pCX43 and COX-2 (both P<0.03). CAV-1 and pCX43 decreased but COX-2 increased with parturition. Significant diet- and labour-stage interactions were evident for CX-43 and pCX43 (P<0.03 and P<0.004 respectively). CX-43 decreased with TL in HFHC animals but was unaltered in CON. pCX-43 fell with labour in CON but remained high in HFHC. OXTR expression was significantly higher in HFHC compared with CON animals (P<0.03). Progesterone was higher in HFHC rats at term (P<0.014) but fell significantly with labour to similar concentrations as CON. Contractility studies identified synchronous contractions of stable amplitude in lean animals, but unstable asynchronous contractions with obesity. Uterine dose response to oxytocin was blunted during labour in HFHC rats with a log EC50 of -8.84 compared with -10.25 M in CON for integral activity (P<0.05). In conclusion, our adiposity model exhibits adverse effects on contractile activity during labour that can be investigated further to unravel the mechanisms causing uterine dystocia in obese women. © 2016 The Author(s).

Our previous work provided evidence that early cervical cancer is locally confined to the Müllerian compartment that develops in women from the embryonic paramesonephric-mesonephric complex. We aimed to investigate if the concept of tumour permeation within ontogenetic domains is also valid for tumour progression and advanced disease. Starting from Carnegie stage 13, four successive steps in the organogenesis of the human uterine cervix were defined and an ontogenetic staging system for cervical cancer based on organ development was described. Histopathological and clinical data of patients with cervical cancer FIGO stages IB-IVA were raised prospectively from Oct 16, 1999, until Dec 20, 2012, and from March 8, 2000, until April 4, 2013, for two surgical trials of ontogenetic compartment resection without adjuvant radiation at the University of Leipzig (total or extended mesometrial resection [TMMR or EMMR]; and [laterally] extended endopelvic resection [LEER]). The primary endpoints of these trials were pathological resection state and locoregional tumour control. Patients who underwent TMMR and EMMR had follow-up assessment every 3-6 months for 5 years, and yearly thereafter. Patients who had (L)EER, every 3-6 months for 10 years, and yearly thereafter. By analysing the presence of disease within the classified tissues and disease outcome in these patients, and by examining relapse patterns, we were able to observe whether surgical excision within developmental compartments was sufficient for disease control. Survival curves were compared using the log-rank test. The effect of ontogenetic tumour stage and pathological tumour stage on overall survival was assessed by Cox proportional hazard models. The trials are registered as an ongoing observational monocentric study at the University of Leipzig Cancer Centre (ULCC012-13-28012013). 367 patients were included in our analysis. Staged organogenesis of the uterine cervix and progressive local growth of cervical carcinoma occur in the same tissue domains. The neoplasm originating in the uterine cervix, ontogenetic tumour stage 1 (oT1, n=217), permeates successively during its malignant progression the tissues developed from the Müllerian compartment (oT2, n=101), the genital metacompartment (oT3, n=38), and the urogenitorectal metacompartment (oT4, n=11). Ontogenetic staging, when comparing patients with oT1 and oT2 disease to those with oT3 and oT4 disease (hazard ratio 5·9, 95% CI 2·2-15·5; p=0·00036) was a better prognostic indicator for survival than pathological staging when comparing pT1b and pT2a with pT2b and pT4 disease (2·0, 95% CI 0·7-5·5; p=0·170). Resection of the stage-related ontogenetically specified tissue domains and their associated regional lymphoid tissues achieved an R0 resection in 363 (99%) of 367 patients and locoregional tumour control at 5 years was 94% (95% CI 92-97). 13 patients had grade 3 or 4 adverse events, the majority of which were urinary (10, 77%). Cervical cancer infiltrates the adult tissues established during ontogeny, pursuing the developmental steps in retrograde sequence. Clinical translation of these insights into ontogenetic tumour staging and compartment resection holds the potential to improve prognostic assessment and curative treatment.

Purpose: The purpose of this study was to analyze tumor heterogeneity based on tumor extent and suggest reappraisal of the system of the International Federation of Gynecology and Obstetrics (FIGO) for Stage III carcinoma of the uterine cervix from a radiotherapeutic viewpoint. Methods and Materials: Between 1986 and 2004, 407 patients with FIGO Stage III (FIGO Stage IIIa in 19 and IIIb in 388) were treated with external beam radiotherapy (RT) and high-dose rate brachytherapy. All patients were reviewed with respect to tumor extent. Patterns of failure and survival parameters were analyzed by use of the chi{sup 2} test andmore » Kaplan-Meier method. Results: The complete response rate was 79.6%, and the 5-year overall survival rates for Stage IIIa and Stage IIIb carcinoma of the cervix were 82.1% and 54.8%, respectively. To determine which parameters of tumor extent had an influence on prognosis for Stage IIIb patients, pelvic wall (PW) extension and hydronephrosis (HD) retained significance on multivariate analysis. Stage IIIb patients were divided into three subgroups according to PW extension and HD: low risk (unilateral PW extension without HD), intermediate risk (HD without PW extension or bilateral PW extension without HD), and high risk (unilateral or bilateral PW extension with HD). The high-risk group had a remarkably low complete response rate, high locoregional failure rate, and low 5-year survival rate compared with the intermediate- and low-risk groups. Conclusions: FIGO Stage III carcinoma of the cervix covers considerably heterogeneous subgroups according to tumor extent. Before initiation of treatment, we suggest that physicians determine a tailored treatment policy based on tumor heterogeneity for each Stage III patient.« less

The effect of two synthetic glucocorticoids, 9α-fluoroprednisolone acetate and dexamethasone (9α-fluoro, 16α-methylprednisolone) was studied on 12 normally breeding cows. Na, Mg, K, Ca and P concentrations were evaluated in the serum and in the uterine fluid at four stages of the estrous cycle. No significant changes were noted in Na and Ca concentration in either serum or uterine fluid. On the other hand, significant changes in the Mg, K and P were observed. Both drugs have caused a decrease in the content of Mg in the serum (P<0.05) during diestrus, a fall in the level of uterine K (P<0.01) during proestrus and a decrease of P during proestrus both in serum (P<0.001 after dexamethasone treatment) and in uterine fluid (P<0.001 for both drugs). It is obvious that the two drugs change the chemical composition of blood and endometrial secretions. This could jeopardize the survival of the spermatozoids and of the ovum as well as the fertilization and the implantation processes. PMID:4259930

Kaposi sarcoma (KS) is a vascular tumor frequently associated with advanced human immunodeficiency virus infection, advanced age, or iatrogenic immunosuppression. Immunohistochemistry for CD31 and CD34, and more recently for FLI1 and D2-40, has been used as ancillary diagnostic tests for KS, despite little information regarding the sensitivities and differential staining patterns of the latter 2 markers in the major clinical subtypes and histologic stages of KS. This retrospective study aims to assess the prevalence of the vascular markers D2-40 and FLI1 in the main clinical subgroups and tumor stages of KS. Twenty-four cases of KS (12 acquired immunodeficiency syndrome [AIDS]-related cases and 12 non-AIDS-related cases; 11 nodular-stage and 13 patch/plaque-stage KS) were stained for CD34, CD31, D2-40, and FLI1 by immunohistochemistry. The distribution of immunoreactivity was compared between the clinical subtypes and tumor stages of KS using the Mann-Whitney test. CD31, CD34, D2-40, and FLI1 strongly and diffusely stained tumor cells in 75%, 92%, 67%, and 92% of AIDS-related cases and 58%, 92%, 67%, and 75% of non-AIDS-related cases, respectively. Differences in the proportions of positive cases between AIDS-related and non-AIDS-related cases did not reach statistical significance. No significant staining differences were observed between nodular- and patch/plaque-stage KS either. There are no differences in the distribution of immunohistochemical reactivity for CD31, CD34, D2-40, or FLI1 between AIDS-related and non-AIDS-related KS or between nodular- and patch/plaque-stage KS. All of the markers studied demonstrated high sensitivity in both clinical settings and both stages of tumor progression.

Purpose: To report the clinical outcomes of children with revised stage I clear cell sarcoma of the kidney (CCSK) using the National Wilms Tumor Study Group (NWTS)-5 staging criteria after multimodality treatment on NWTS 1-5 protocols. Methods and Materials: All CCSK patients enrolled in the National Wilms Tumor Study Group protocols had their pathology slides reviewed, and only those determined to have revised stage I tumors according to the NWTS-5 staging criteria were included in the present analysis. All patients were treated with multimodality therapy according to the NWTS 1-5 protocols. Results: A total of 53 children were identified asmore » having stage I CCSK. All patients underwent primary surgery with radical nephrectomy. The chemotherapy regimens used were as follows: regimen A, C, F, or EE in 4 children (8%); regimen DD or DD4A in 33 children (62%); regimen J in 4 children (8%); and regimen I in 12 children (22%). Forty-six patients (87%) received flank radiation therapy (RT). Seven children (13%) did not receive flank RT. The median delay between surgery and the initiation of RT was 9 days (range, 3-61). The median RT dose was 10.8 Gy (range, 10-36). The flank RT doses were as follows: 10.5 or 10.8 Gy in 25 patients (47%), 11-19.9 Gy in 2 patients (4%), 20-29.9 Gy in 9 patients (17%), and 30-40 Gy in 10 patients (19%). The median follow-up for the entire group was 17 years (range, 2-36). The relapse-free and cancer-specific survival rate was 100% at the last follow-up examination. Conclusions: The present results have demonstrated that children with revised stage I CCSK using the NWTS-5 staging criteria have excellent survival rates despite the use of varying RT doses and chemotherapy regimens in the NWTS 1-5 protocols.« less

The Influence of Bearing-Down Technique on the Fetal Heart Rate during the Second Stage of Labor.

NASA Astrophysics Data System (ADS)

Perlis, Deborah Woolley

This experimental study contrasted the effects of sustained bearing-down efforts with short bearing-down efforts during the first twelve contractions of the second stage of labor. A single subject design with intrasubject replication was used to compare the incidence, duration, and amplitude of fetal heart rate decelerations, as well as the beat-to-beat variability of those decelerations. Neonatal outcome was evaluated with umbilical arterial cord blood pH values and the one- and five-minute APGAR scores. Thirty -two nulliparous women alternated the use of vigorous, sustained Valsalva-style bearing-down efforts with shorter efforts called minipushes every three contractions during the second stage of labor. Sixteen women began the second stage using the Valsalva-style bearing-down technique; sixteen began the second stage using the minipush. The fetal heart rate was recorded by an internal fetal scalp electrode. Uterine contractility was measured by an internal uterine pressure catheter. A repeated-measures MANOVA showed a significant interaction between the order of implementation of the bearing-down techniques and the amplitude of the fetal heart rate decelerations. A similar comparison of the duration of the decelerations showed no significant differences between the two bearing-down techniques. Likewise, analysis of the incidence of fetal heart rate decelerations and the magnitude of the beat-to-beat variability revealed no significant differences between the two techniques.

Uterine serous carcinoma (USC) is an aggressive type 2 endometrial cancer. Data on prognostic factors for patients with early-stage USC without adjuvant therapy are limited. This study aims to assess the baseline recurrence risk of early-stage USC patients without adjuvant treatment and to identify prognostic factors and patients who need adjuvant therapy. Sixty-eight patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II USC between 1997 and 2016 were included. All the cases did not undergo adjuvant treatment as institutional practice. Clinicopathological features, recurrence patterns, and survival outcomes were analyzed to determine prognostic factors. FIGO stages IA, IB, and II were observed in 42, 7, and 19 cases, respectively. Median follow-up time was 60 months. Five-year disease-free survival (DFS) and overall survival (OS) rates for all cases were 73.9% and 78.0%, respectively. On multivariate analysis, cervical stromal involvement and positive pelvic cytology were significant predictors of DFS and OS, and ≥1/2 myometrial invasion was also a significant predictor of OS. Of 68 patients, 38 patients had no cervical stromal invasion or positive pelvic cytology and showed 88.8% 5-year DFS and 93.6% 5-year OS. Cervical stromal invasion and positive pelvic cytology are prognostic factors for stage I-II USC. Patients with stage IA or IB USC showing negative pelvic cytology may have an extremely favorable prognosis and need not receive any adjuvant therapies. Copyright © 2018.

Our group previously documented the first, very rare case of primary gastric-type mucinous adenocarcinoma of the uterine corpus. Although this type of endometrial cancer appears to be similar to the gastric-type adenocarcinoma of the uterine cervix, its main symptoms, appearance on magnetic resonance imaging (MRI) and prognosis have not been fully elucidated due to its rarity. We herein describe an additional case of gastric-type mucinous adenocarcinoma of the endometrium and review the relevant literature. The two cases at our institution (Kyoto University Hospital, Kyoto, Japan) involved postmenopausal women with a primary complaint of abnormal genital bleeding. Microscopic examination of the hysterectomy specimens indicated a highly differentiated mucinous adenocarcinoma with a desmoplastic stromal reaction. Immunohistochemistry for HIK1083 and/or MUC6 was positive in both cases, suggesting a gastric phenotype. Both patients were diagnosed at an advanced stage, they relapsed or recurred immediately after adjuvant chemotherapy, and eventually succumbed to the disease. The main symptom of gastric-type mucinous adenocarcinoma of the uterine cervix is watery discharge, whereas abnormal genital bleeding in addition to watery discharge is mainly observed in the mucinous type of endometrial adenocarcinoma. Cystic cavities in the tumor are present on MRI in cases of endometrial origin, and prognosis is very poor due to resistance to chemotherapy. Thus, gastric-type mucinous adenocarcinoma of the uterine endometrium exhibits a clinical behavior that is similar to tumors originating from the uterine cervix, but is associated with distinguishing clinical symptoms. The incidence of gastric-type endometrial adenocarcinoma may be higher than expected. PMID:27123265

Embryo implantation requires that the uterus differentiate into the receptive state. Failure to attain uterine receptivity will impede blastocyst attachment and result in a compromised pregnancy. The molecular mechanism by which the uterus transitions from the prereceptive to the receptive stage is complex, involving an intricate interplay of various molecules. We recently found that mice with uterine deletion ofMsxgenes (Msx1(d/d)/Msx2(d/d)) are infertile because of implantation failure associated with heightened apicobasal polarity of luminal epithelial cells during the receptive period. However, information on Msx's roles in regulating epithelial polarity remains limited. To gain further insight, we analyzed cell-type-specific gene expression by RNA sequencing of separated luminal epithelial and stromal cells by laser capture microdissection fromMsx1(d/d)/Msx2(d/d)and floxed mouse uteri on d 4 of pseudopregnancy. We found that claudin-1, a tight junction protein, and small proline-rich (Sprr2) protein, a major component of cornified envelopes in keratinized epidermis, were substantially up-regulated inMsx1(d/d)/Msx2(d/d)uterine epithelia. These factors also exhibited unique epithelial expression patterns at the implantation chamber (crypt) inMsx1(f/f)/Msx2(f/f)females; the patterns were lost inMsx1(d/d)/Msx2(d/d)epithelia on d 5, suggesting important roles during implantation. The results suggest thatMsxgenes play important roles during uterine receptivity including modulation of epithelial junctional activity.-Sun, X., Park, C. B., Deng, W., Potter, S. S., Dey, S. K.

The great white shark (Carcharodon carcharias) exhibits viviparous and oophagous reproduction. A 4950 mm total length (TL) gravid female accidentally caught by fishermen in the Okinawa Prefecture, Southern Japan carried six embryos (543-624 mm TL, three in each uterus). Both uteri contained copious amounts of yellowish viscous uterine fluid (over 79.2 litres in the left uterus), nutrient eggs and broken egg cases. The embryos had yolk stomachs that had ruptured, the mean volume of which was approximately 197.9 ml. Embryos had about 20 rows of potentially functional teeth in the upper and lower jaws. Periodic acid Schiff (PAS)-positive substances were observed on the surface and in the cytoplasm of the epithelial cells, and large, secretory, OsO4-oxidized lipid droplets of various sizes were distributed on the surface of the villous string epithelium on the uterine wall. Histological examination of the uterine wall showed it to consist of villi, similar to the trophonemata of Dasyatidae rays, suggesting that the large amount of fluid found in the uterus of the white shark was likely required for embryo nutrition. We conclude that: (1) the lipid-rich fluid is secreted from the uterine epithelium only in early gestation before the onset of oophagy, (2) the embryos probably use the abundant uterine fluid and encased nutrient eggs for nutrition at this stage of their development, and (3) the uterine fluid is the major source of embryonic nutrition before oophagy onset. This is the first record of the lipid histotrophy of reproduction among all shark species. © 2016. Published by The Company of Biologists Ltd.

Molecular piracy: manipulation of the ubiquitin system by Kaposi's sarcoma-associated herpesvirus.

Fujimuro, Masahiro; Hayward, S Diane; Yokosawa, Hideyoshi

2007-01-01

Ubiquitination, one of several post-translational protein modifications, plays a key role in the regulation of cellular events, including protein degradation, signal transduction, endocytosis, protein trafficking, apoptosis and immune responses. Ubiquitin attachment at the lysine residue of cellular factors acts as a signal for endocytosis and rapid degradation by the 26S proteasome. It has recently been observed that viruses, especially oncogenic herpesviruses, utilise molecular piracy by encoding their own proteins to interfere with regulation of cell signalling. Kaposi's sarcoma- associated herpesvirus (KSHV) manipulates the ubiquitin system to facilitate cell proliferation, anti-apoptosis and evasion from immunity. In this review, we will describe the strategies used by KSHV at distinct stages of the viral life-cycle to control the ubiquitin system and promote oncogenesis and viral persistence.

Alzheimer’s disease (AD) is characterized by a long pre-clinical phase (20–30 years), during which significant brain pathology manifests itself. Disease mechanisms associated with pathological hallmarks remain elusive. Most processes associated with AD pathogenesis, such as inflammation, synaptic dysfunction, and hyper-phosphorylation of tau are dependent on protein kinase activity. The objective of this study was to determine the involvement of protein kinases in AD pathogenesis. Protein kinase activity was determined in postmortem hippocampal brain tissue of 60 patients at various stages of AD and 40 non-demented controls (Braak stages 0-VI) using a peptide-based microarray platform. We observed an overall decrease of protein kinase activity that correlated with disease progression. The phosphorylation of 96.7% of the serine/threonine peptides and 37.5% of the tyrosine peptides on the microarray decreased significantly with increased Braak stage (p-value <0.01). Decreased activity was evident at pre-clinical stages of AD pathology (Braak I-II). Increased phosphorylation was not observed for any peptide. STRING analysis in combination with pathway analysis and identification of kinases responsible for peptide phosphorylation showed the interactions between well-known proteins in AD pathology, including the Ephrin-receptor A1 (EphA1), a risk gene for AD, and sarcoma tyrosine kinase (Src), which is involved in memory formation. Additionally, kinases that have not previously been associated with AD were identified, e.g., protein tyrosine kinase 6 (PTK6/BRK), feline sarcoma oncogene kinase (FES), and fyn-associated tyrosine kinase (FRK). The identified protein kinases are new biomarkers and potential drug targets for early (pre-clinical) intervention. PMID:26519433

Evaluate rates of chemotherapy and radiotherapy delivery in the treatment of uterine carcinosarcoma, and compare clinical outcomes of treated and untreated patients. The National Cancer Database was queried to identify patients diagnosed with uterine carcinosarcoma between 2003 and 2011. The impact of chemotherapy on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. A total of 10,609 patients met study eligibility criteria. Stages I, II, III, and IV disease accounted for 2997 (28.2%), 642 (6.1%), 2037 (19.2%), and 1316 (12.4%) of the study population, respectively. Most patients (91.0%) underwent definitive surgery, and lymphadenectomy was performed in 68.7% of the patients. Chemotherapy was administered in 2378 (22.4%) patients, radiotherapy to 2196 (20.7%), adjuvant chemo-radiation to 1804 (17.0%), and 4231 (39.9%) of women did not received adjuvant therapy. Utilization of chemotherapy became more frequent over time. Over the entire study period, after adjusting for race, period of diagnosis, facility location, facility type, insurance provider, stage, age, treatment modality, lymph node dissection, socioeconomic status, and comorbidity index, there was an association between treatment modality and survival. The lowest hazard ratio observed was in patients that received chemo-radiation. The strongest quantitative predictor of death was stage at the time of diagnosis. In addition, surgical treatment, lymph node dissection, most recent time-periods, lower comorbidity index, and higher socioeconomic status were associated with improved survival. The overall rates of chemotherapy use have increased over time. Adjuvant chemotherapy and chemo-radiation were associated with improved survival. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate outcomes following laparoscopic single sheet mesh sacrohysteropexy for the management of uterine prolapse. One hundred and fifty-nine women underwent the procedure between August 2010 and August 2014. One hundred and forty-four patients completed the follow up assessment. At each visit, the prolapse symptoms were assessed using the prolapse quality-of-life (P-QOL) questionnaire and objectively with the use of the Pelvic Organ Prolapse Quantification (POPQ) score. The subjective outcomes were also evaluated with the use of the Patient Global Impression of Improvement (PGII) questionnaires. Perioperative complications and further surgery for prolapse were evaluated. Women who conceived following the procedure were evaluated for pregnancy outcomes and prolapse recurrence. Pre-operatively, 85% (135/159) had uterine prolapse ≥ stage 2. Postoperatively, 95.1% (137/144) of women had anatomical success rate defined as stage 0 uterine descent. Eighty-two percent (118/144) of women reported cure of prolapse symptoms and feeling "much better" or "very much better" on postoperative PGII assessment. Eight women (5%) became pregnant following the laparoscopic sacrohysteropexy- seven had full term pregnancies and one had a miscarriage. Six out of the seven (86%) had stage 0 apical prolapse and PGII of "much better" at 6 months postpartum. One patient had symptomatic prolapse recurrence and underwent perineorrhaphy at 3 years. Laparoscopic single sheet mesh sacrohysteropexy is associated with subjective and objective improvement in prolapse symptoms and QoL that is maintained up to 48 months. Laparoscopic sacrohysteropexy can be offered to women desiring future fertility; however, further research is needed to advise on best surgical approach in women of childbearing age. Neurourol.

Subsets of primitive round-cell sarcomas remain difficult to diagnose and classify. Among these is a rare round-cell sarcoma that harbors a CIC gene rearrangement known as CIC-rearranged undifferentiated round-cell sarcoma, which is most commonly fused to the DUX4 gene. Owing to its aggressive clinical behavior and potential therapeutic implications, accurate identification of this novel soft tissue sarcoma is necessary. Definitive diagnosis requires molecular confirmation, but only a few centers are as yet able to perform this test. Several studies have shown that PEA3 subfamily genes, notably ETV4 (belonging to the family of ETS transcription factors), are upregulated in CIC-rearranged undifferentiated round-cell sarcomas. We performed a detailed immunohistochemical analysis to investigate ETV4 expression in CIC-rearranged undifferentiated round-cell sarcomas and their potential mimics (especially Ewing sarcomas). The study cohort included 17 cases of CIC-rearranged undifferentiated round-cell sarcomas, and 110 tumors that morphologically mimic CIC-rearranged undifferentiated round-cell sarcomas: 43 Ewing sarcomas, 25 alveolar rhabdomyosarcomas, 20 poorly differentiated round-cell synovial sarcomas, 10 desmoplastic round-cell tumors, 5 BCOR-CCNB3 sarcomas, 5 lymphoblastic lymphomas, and 2 rhabdoid tumors. All CIC-rearranged undifferentiated round-cell sarcomas (on core needle biopsies and open biopsies) were ETV4-positive with a strong diffuse nuclear pattern. Among the other 110 tumors, only six cases (four Ewing sarcomas, one alveolar rhabdomyosarcoma, and one desmoplastic round-cell tumor) showed focal (<5% of tumor cells) and very weak nuclear expression of ETV4; all other tumors were completely negative for ETV4. We conclude that systematic immunohistochemical analysis of ETV4 makes it possible to diagnose undifferentiated round-cell sarcomas (with no molecular markers for sarcoma-associated translocation) such as CIC-rearranged undifferentiated round-cell sarcoma.

Labor induction is a common practice to promote uterine contractions and labor onset. Uterine electrohysterogram (EHG) has proved its suitability for characterizing the uterus electrophysiological condition in women with spontaneous labor. The aim of this study was to characterize and compare uterine myoelectrical activity during the first 4 h in response to labor induction drugs, Misoprostol (G1) and Dinoprostone (G2), by analyzing the differences between women who achieved active phase of labor and those who did not (successful and failed inductions). A set of temporal, spectral and complexity parameters were computed from the EHG-bursts. As for successful inductions, statistical significant and sustained increases with respect to basal period were obtained for EHG amplitude, mean frequency, uterine activity index (UAI) and Teager, after 60' for the G1 group; duration, amplitude, number of contractions and UAI for the G2 group, after 120'. Moreover, Teager showed statistical significant and sustained differences between successful and failed inductions (1.43 ± 1.45 µV 2. Hz 2. 10 5  vs. 0.40 ± 0.26 µV 2. Hz 2. 10 5 after 240') for the G1 group, but not in the G2 group, probably due to the slower pharmacokinetics of this drug. These results revealed that EHG could be useful for successful induction prediction in the early stages of induction, especially when using Misoprostol. Copyright © 2018 Elsevier Ltd.

To determine the effect of epidural analgesia on biochemical markers of stress, plasma oxytocin concentrations and frequency of uterine contractions during the first stage of labour. Nine nulliparous women, in spontaneous labour, with a singleton fetus and cervical dilatation < or = 5 cm were enrolled. Epidural bupivacaine 0.25% (range 10-14 ml) was administered and bilateral sensory blockade to ice (T8-L4) achieved. Blood samples were collected before the epidermal block and every 10 min for one hour after the block was achieved for the measurement of plasma beta-endorphin, cortical, glucose, lactate and oxytocin concentrations. No exogenous oxytocin was given. Intensity of pain was assessed at the time of the blood sampling using a 10 cm visual analogue scale (VAS). The frequency of uterine contractions was recorded for 60 min before and after the epidural block. There was a decrease in plasma beta-endorphin and cortisol concentrations after epidural block (P < 0.01). There were no changes in plasma glucose and lactate concentrations. The mean VAS for pain decreased 10 min after epidural block was achieved and remained < 2 throughout the study period (P < 0.001). Mean plasma oxytocin concentrations did not change. The frequency of uterine contractions before and after the epidural block was similar. The metabolic stress response to the pain of labour was attenuated by epidural analgesia. In contrast, plasma oxytocin concentration and frequency of uterine contractions were unaffected by the attenuation of metabolic stress response.

Photodynamic therapy (PDT) was performed with a new photosensitizer, a water soluble form of chlorins (Radachlorin, Russia) possessing an absorption peak around 662 nm. As light source there was used the diode laser (ML-662-SP, Russia) with 662 nm wavelength and 2.5 W optical power. The sensitizer had passed broad pre-clinical in vitro and in vivo studies, which showed safety and efficiency of it. PDT was applied to 51 patients with basal cell cancer of the skin (about 60% of all cases), breast cancer, lip cancer, melanoma, cancer of esophagus, stomach, and rectum, cancer and leucoplacia of vulva, malignant ganglioneuroma, sarcoma of soft tissue, cancer and reticular sarcoma of thyroid gland, cancer of ductus choledochus. Most of non-basalioma patients had either forth stage or recurrence of disease. The sensitizer was injected intravenously or applied externally (Radachlorin gel). There were used surface, endoscopic, and interstitial ways of irradiation. Full tumor regression with excellent cosmetic effect was reached in 100% cases of 1-3 stage basal cell cancer patients treated with intravenous Radachlorin injection. In most other (non-basalioma) cases significant regression of tumors and improvement of life quality of patients (recanalization and regain of conductivity) was obtained.

The aim of this study was to identify the prognostic factors of uterine leiomyosarcoma (ULMS). We reviewed 60 cases of surgically resected ULMSs and investigated conventional clinicopathological factors, together with the expression of insulin-like growth factor II messenger RNA-binding protein-3 (IMP3), hormone receptors and cell cycle regulatory markers by immunohistochemistry. Mediator complex subunit 12 (MED12) mutation analysis was also performed. Univariate analyses revealed that advanced stage (P < 0.0001), older age (P = 0.0244) and IMP3 expression (P = 0.0011) were significant predictors of a poor outcome. Multivariate analysis revealed advanced stage (P < 0.0001) and IMP3 (P = 0.0373) as independent predictors of a poor prognosis. Expressions of cell cycle markers and hormone receptors, and MED12 mutations (12% in ULMSs) were not identified as prognostic markers in this study. IMP3 expression in ULMS could be a marker of a poor prognosis. © 2017 John Wiley & Sons Ltd.

Vaginal radical trachectomy (RT) ligates and cuts several arteries supplying the uterus. Changes of blood supply to the uterus in two patients who experienced pregnancy and delivery were studied by using 3-D CT scanning. Effects of changes of blood supply to the uterus on the pregnancy courses were also examined. Vascular distribution in the uterus was studied in two patients who received vaginal RT after delivery. Effects of changes of vascular distribution after vaginal RT were studied with respect to pregnancy courses and cervical functions. New arterial vascularization from the ascending branches of uterine arteries or other arteries occurred, and these new vessels seemed to supply blood to the remaining cervix. Differences of fetal growth and histopathological changes in the placenta between the two patients could not be detected. Ligation and cutting of several supplying arteries by RT induces new arterial vascularization and it does not seem to affect fetal growth and placental function.

Breast and splenic metastases of squamous cell carcinoma from the uterine cervix: a case report

PubMed Central

2014-01-01

Introduction Metastases to the breast from extramammary malignancies are infrequent, the most common primary sites are malignant melanoma, leukemia, lymphoma, and cancer of the lung, stomach, prostate and ovary. The cervical origin is exceptional. Splenic metastasis from squamous cell carcinoma of the cervix is also rare. To the best of our knowledge, only three cases of isolated splenic metastasis have been reported in the literature. Case presentation We describe the case of a 55-year-old North African woman who presented with a nodule in her left breast eight months after treatment for stage IIB squamous cell uterine cervical carcinoma. The excisional biopsy with histological study demonstrated a poorly differentiated squamous cell carcinoma. A computed tomography scan revealed a splenic secondary location. Conclusions We report here a case of two unusual metastatic sites of uterine cervical carcinoma, the breast and spleen. It is the first case of this association without widespread disease.

Endometrial stromal sarcomas (ESS) are rare uterine malignant mesenchymal neoplasms, which are currently treated by surgery, as effective adjuvant therapies have not yet been established. Tyrosine kinase inhibitors have rarely been applied in ESS therapy, with few reports describing imatinib responsivity. The aim of this study was to analyze the status of different tyrosine kinase receptors in an ESS series, in order to evaluate their potential role as molecular targets. Immunohistochemistry was performed for EGFR, c-KIT, PDGFR-α, PDGFR-β, and ABL on 28 ESS. EGFR, PDGFR-α, and PDGFR-β gene expression was investigated by real-time polymerase chain reaction (qRT-PCR) on selected cases. "Hot-spot" mutations were screened for on EGFR, c-KIT, PDGFR-α, and PDGFR-β genes, by sequencing. All analysis was executed from formalin-fixed, paraffin-embedded specimens. Immunohistochemical overexpression of 2 or more tyrosine kinase receptors was observed in 18 of 28 tumors (64%), whereas only 5 tumors were consistently negative. Gene expression profiles were concordant with immunohistochemical overexpression in only 1 tumor, which displayed both high mRNA levels and specific immunoreactivity for PDGFR-α, and PDGFR-β. No activating mutations were found on the tumors included in the study. This study confirms that TKRs expression is frequently observed in ESS. Considering that the responsiveness to tyrosine kinase inhibitors is known to be related to the presence of specific activating mutations or gene over-expression, which are not detectable in ESS, TKRs immunohistochemical over-expression alone should not be considered as a reliable marker for targeted therapies in ESS. Specific post-translational abnormalities, responsible for activation of TKRs, should be further investigated.

Uterine serous carcinoma (USC) is an aggressive histologic subtype of endometrial cancer that shares similarities to serous ovarian cancer, with a propensity for spread to the upper abdomen, a high recurrence rate, and a poor prognosis. The aim of this study was to determine whether the traditional surgical staging procedure for endometrial cancer was adequate for USC or whether a more extensive surgery, similar to the staging procedure for ovarian cancer, needs to be performed. Specifically, the roles of omentectomy and sentinel lymph node (SLN) mapping were evaluated. We retrospectively identified cases of presumed clinical stage I USC at our institution from April 2005 to March 2014. Medical records were reviewed for the following information: age at diagnosis, preoperative imaging, operative findings, surgical procedure, and final histology with definitive International Federation of Gynecology and Obstetrics stage. A total of 39 patients with presumed clinical stage I USC were identified. According to the final pathology report, the surgical stage was as follows: 17 stage IA (44%), 8 stage IB (20%), 3 stage II (8%), 2 stage IIIA (5%), 6 stage IIIC1 (15%), 1 IIIC2 (3%), and 2 stage IVB (5%). Therefore, 14 patients (36%) were surgically upstaged, but none of the patients had their clinical disease upstaged by virtue of finding microscopic metastatic disease in an otherwise normal-looking omentum. Sentinel lymph node mapping was performed in 19 patients (42%). Sensitivity and negative predictive value of SLN mapping were 100% when at least 1 SLN was identified. The detection of microscopic disease in radiologically and clinically normal-appearing omentum seems to be rare in USC. Sentinel lymph node mapping seems to be valuable in the serous subtype of endometrial cancer. A less extensive surgery may be possible in patients with USC as it seems to provide the same information as a more extensive surgery.

Soft-tissue sarcomas occurring in the abdomen and pelvis are an uncommon but important group of malignancies. Recent changes to the World Health Organization classification of soft-tissue tumors include the movement of gastrointestinal stromal tumors (GISTs) into the soft-tissue tumor classification. GIST is the most common intraperitoneal sarcoma. Liposarcoma is the most common retroperitoneal sarcoma, and leiomyosarcoma is the second most common. GIST, liposarcoma, and leiomyosarcoma account for the majority of sarcomas encountered in the abdomen and pelvis and are discussed in part 1 of this article. Undifferentiated pleomorphic sarcoma (previously called malignant fibrous histiocytoma), dermatofibrosarcoma protuberans, solitary fibrous tumor, malignant peripheral nerve sheath tumor, rhabdomyosarcoma, extraskeletal chondro-osseous sarcomas, vascular sarcomas, and sarcomas of uncertain differentiation uncommonly arise in the abdomen and pelvis and the abdominal wall. Although these lesions are rare sarcomas and their imaging features overlap, familiarity with the locations where they occur and their imaging features is important so they can be diagnosed accurately. The anatomic location and clinical history are important factors in the differential diagnosis of these lesions because metastasis, more-common sarcomas, borderline fibroblastic proliferations (such as desmoid tumors), and endometriosis have imaging findings that overlap with those of these uncommon sarcomas. In this article, the clinical, pathologic, and imaging findings of uncommon soft-tissue sarcomas of the abdomen and pelvis and the abdominal wall are reviewed, with an emphasis on their differential diagnosis.

About 30% of endometrial cancer (EC) patients are diagnosed at an advanced stage of the disease, which is associated with a drastic decrease in the 5-year survival rate. The identification of biomarkers in uterine aspirate samples, which are collected by a minimally invasive procedure, would improve early diagnosis of EC. We present a sequential workflow to select from a list of potential EC biomarkers, those which are the most promising to enter a validation study. After the elimination of confounding contributions by residual blood proteins, 52 potential biomarkers were analyzed in uterine aspirates from 20 EC patients and 18 non-EC controls by a high-resolution accurate mass spectrometer operated in parallel reaction monitoring mode. The differential abundance of 26 biomarkers was observed, and among them ten proteins showed a high sensitivity and specificity (AUC > 0.9). The study demonstrates that uterine aspirates are valuable samples for EC protein biomarkers screening. It also illustrates the importance of a biomarker verification phase to fill the gap between discovery and validation studies and highlights the benefits of high resolution mass spectrometry for this purpose. The proteins verified in this study have an increased likelihood to become a clinical assay after a subsequent validation phase.

To examine survival of women with stage IV uterine carcinosarcoma (UCS) who received neoadjuvant chemotherapy followed by hysterectomy. This is a nested case-control study within a retrospective cohort of 1192 UCS cases. Women who received neoadjuvant chemotherapy followed by hysterectomy based-surgery for stage IV UCS (n = 26) were compared to those who had primary hysterectomy-based surgery without neoadjuvant chemotherapy for stage IV UCS (n = 120). Progression-free survival (PFS) and cause-specific survival (CSS) were examined. The most common regimen for neoadjuvant chemotherapy was carboplatin/paclitaxel (53.8%). Median number of neoadjuvant chemotherapy cycles was 4. PFS was similar between the neoadjuvant chemotherapy group and the primary surgery group (unadjusted-hazard ratio [HR] 1.19, 95% confidence interval [CI] 0.75-1.89, P = 0.45). Similarly, CSS was comparable between the two groups (unadjusted-HR 1.13, 95%CI 0.68-1.90, P = 0.64). When the types of neoadjuvant chemotherapy regimens were compared, women who received a carboplatin/paclitaxel regimen had better survival outcomes compared to those who received other regimens: PFS, unadjusted-HR 0.38, 95%CI 0.15-0.93, P = 0.027; and CSS, unadjusted-HR 0.21, 95%CI 0.07-0.61, P = 0.002. Our study found that there is no statistically significant difference in survival between women with stage IV UCS who are tolerated neoadjuvant chemotherapy and those who undergo primary surgery. © 2017 Wiley Periodicals, Inc.

The epidemiology of classic, African, and immunosuppressed Kaposi's sarcoma.

1991-01-01

The etiology of Kaposi's sarcoma remains somewhat obscure. While lesions of classic Kaposi's sarcoma, African Kaposi's sarcoma, and immunosuppressed Kaposi's sarcoma have been found to be indistinguishable from one another, the reasons for the variations in type and severity have not been established. The origin of the spindle cell is yet to be agreed on. Geographic variation does not seem as important as ethnic variation. The very young and the very old, perhaps two ages of weakened immunity, tend to have a higher incidence of Kaposi's sarcoma. Children and AIDS patients tend to develop more virulent disease. Males tend to get Kaposi's sarcoma at higher rates than do females. Jewish and Mediterranean males have the highest incidence of classic Kaposi's sarcoma, and African Bantu have the highest incidence of African Kaposi's sarcoma, classifications which do not apply to the Kaposi's sarcoma population in the United States. Male homosexuals have much higher incidence of Kaposi's sarcoma than do male heterosexuals, but since the early 1980s, its incidence as the presenting manifestation of AIDS has decreased dramatically. There is no unequivocal association with HLA haplotype (though DR5 carriers may be at especially high risk) or evidence of family clustering. There is an impressive but not always consistent association between Kaposi's sarcoma development and immunodeficiency. Environmental factors, such as nitrite use, immunosuppression, and repeated cytomegalovirus infection, are associated with Kaposi's sarcoma, but the exact mechanism is unclear and the associations remain inconsistent. Finally, it is still unclear if there is a causative infectious agent for Kaposi's sarcoma. While cytomegalovirus has been linked to Kaposi's sarcoma, there are weaknesses in its hypothetical role as an etiologic agent as is the case for HIV itself.(ABSTRACT TRUNCATED AT 400 WORDS)

Bovine embryo growth involves a complex interaction between the developing embryo and the growth-promoting potential of the uterine environment. We have previously established links between embryonic factors (embryo stage, embryo gene expression), maternal factors (progesterone, body condition score), and embryonic growth to 8 d after bulk transfer of Day 7 in vitro-produced blastocysts. In this study we recovered blastocysts on Days 7 and 15 after artificial insemination to test the hypothesis that in vivo and in vitro embryos follow a similar growth program. We conducted our study using 4 commercial farms and repeated our study over 2 yr (2014, 2015), with data available from 2 of the 4 farms in the second year. Morphological and gene expression measurements (196 candidate genes) of the Day 7 embryos were measured and the progesterone concentration of the cows were measured throughout the reproductive cycle as a reflection of the state of the uterine environment. These data were also used to assess the interaction between the uterine environment and the developing embryo and to examine how well Day 7 embryo stage can be predicted from the Day 7 gene expression profile. Progesterone was not a strong predictor of in vivo embryo growth to Day 15. This contrasts with a range of Day 7 embryo transfer studies which demonstrated that progesterone is a very good predictor of embryo growth to Day 15. Our analysis demonstrates that in vivo embryos are 3 times less sensitive to progesterone than in vitro-transferred embryos (up to Day 15). This highlights that caution must be applied when extrapolating the results of in vitro embryo transfer studies to the in vivo situation. The similar variance in measured and predicted (based on Day 15 length) Day 7 embryo stage indicate low stochastic perturbations for in vivo embryo growth (large stochastic growth effects would generate a significantly larger standard deviation in measured embryo length on Day 15). We also identified that Day 7 embryo stage could be predicted based on the Day 7 gene expression profile (58% overall success rate for classification of 5 embryo stages). Our analysis also associated genes with each developmental stage and demonstrates the high level of temporal regulation of genes that occurs during early embryonic development.

Comprehensive and Integrated Genomic Characterization of Adult Soft Tissue Sarcomas.

PubMed

2017-11-02

Sarcomas are a broad family of mesenchymal malignancies exhibiting remarkable histologic diversity. We describe the multi-platform molecular landscape of 206 adult soft tissue sarcomas representing 6 major types. Along with novel insights into the biology of individual sarcoma types, we report three overarching findings: (1) unlike most epithelial malignancies, these sarcomas (excepting synovial sarcoma) are characterized predominantly by copy-number changes, with low mutational loads and only a few genes (TP53, ATRX, RB1) highly recurrently mutated across sarcoma types; (2) within sarcoma types, genomic and regulomic diversity of driver pathways defines molecular subtypes associated with patient outcome; and (3) the immune microenvironment, inferred from DNA methylation and mRNA profiles, associates with outcome and may inform clinical trials of immune checkpoint inhibitors. Overall, this large-scale analysis reveals previously unappreciated sarcoma-type-specific changes in copy number, methylation, RNA, and protein, providing insights into refining sarcoma therapy and relationships to other cancer types.

Current therapies for sarcomas are often inadequate. This study sought to identify actionable gene targets by selective targeting of the molecular networks that support sarcoma cell proliferation. Silencing of asparagine synthetase (ASNS), an amidotransferase that converts aspartate into asparagine, produced the strongest inhibitory effect on sarcoma growth in a functional genomic screen of mouse sarcomas generated by oncogenic Kras and disruption of Cdkn2a. ASNS silencing in mouse and human sarcoma cell lines reduced the percentage of S phase cells and impeded new polypeptide synthesis. These effects of ASNS silencing were reversed by exogenous supplementation with asparagine. Also, asparagine depletion via the ASNS inhibitor amino sulfoximine 5 (AS5) or asparaginase inhibited mouse and human sarcoma growth in vitro, and genetic silencing of ASNS in mouse sarcoma cells combined with depletion of plasma asparagine inhibited tumor growth in vivo.

Sarcomas are cancers arising from the mesenchymal layer that affect children, adolescents, young adults, and adults. Although most sarcomas are localized, many display a remarkable predilection for metastasis to the lungs, liver, bones, subcutaneous tissue, and lymph nodes. Additionally, many sarcoma patients presenting initially with localized disease may relapse at metastatic sites. While localized sarcomas can often be cured through surgery and often radiation, controversies exist over optimal management of patients with metastatic sarcoma. Combinations of chemotherapy are the most effective in many settings, and many promising new agents are under active investigation or are being explored in preclinical models. Metastatic sarcomas are excellent candidates for novel approaches with additional agents as they have demonstrated chemosensitivity and affect a portion of the population that is motivated toward curative therapy. In this paper, we provide an overview on the common sarcomas of childhood (rhabdomyosarcoma), adolescence, and young adults (osteosarcoma, Ewing sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor) and older adults (leiomyosarcoma, liposarcoma, and undifferentiated high grade sarcoma) in terms of the epidemiology, current therapy, promising therapeutic directions and outcome with a focus on metastatic disease. Potential advances in terms of promising therapy and biologic insights may lead to more effective and safer therapies; however, more clinical trials and research are needed for patients with metastatic sarcoma.

Background The association of the human herpesvirus-8/Kaposi's sarcoma (KS)-associated herpesvirus (HHV-8/KSHV) serology with various malignancies in Tanzania is not currently well established while previous studies were based on either PCR or immunofluorescence assays [IFA] but not with a sensitive enzyme-linked immunosorbent assay (ELISA). Selected archival diagnostic biopsies (n = 184) and sera from indigenous patients with KS (n = 120), non-KS tumors (n = 24) and non-neoplastic lesions (n = 40) at Muhimbili National Hospital (MNH), Tanzania, were evaluated by diagnostic histopathology, immunohistology [anti-HHV-8 latency-associated nuclear antigen (LANA)] and serology for HIV (ELISA) and HHV-8 (IFA and ELISA). Results About 66.3% (n = 122) cases including AIDS-associated Kaposi's sarcoma (AKS) (n = 93), reactive conditions (n = 28) and only one non-KS tumour were HIV positive. Endemic KS (EKS) patients were mostly males (96.3%, 26/27) who were less (69.9%, 65/93) predominant in AIDS-associated (AKS). A high (89%) percentage of patients with anti-HHV-8 antibodies was found in the cohort including the HIV positive (92%) cases, males (81.2%), KS patients (93%), non-KS tumors (92%), and reactive conditions (75%). All HHV-8 seronegative KS cases were nodular stage whereas both sera and corresponding biopsies from early stage KS were HHV-8+. Assay sensitivity, positive predictive value (PPV) and specificity were 98.6%, 93.5% and 16.7% for IFA and 93.5%, 98.6% and 50.0% for ELISA respectively. Conclusion HHV-8 seroprevalence at MNH appears high as expected among AKS cases and males but also in non-KS patients. ELISA showed a combination of high HHV-8 sensitivity as well as higher PPV and specificity than IFA which however, showed higher sensitivity. The apparent stage-dependent, inverted serum HHV-8 immunoreactivity supports a notion of viral immune-segregation during KS development. Routine HHV-8 screening should be considered particularly in patients at risk of KS and for selection of blood/organ donations. PMID:18590556

Difference in prognosis between grade 3 endometrioid carcinoma (G3EC) of the endometrium and uterine serous carcinoma (USC) is controversial. In this study, we further evaluated the difference in prognosis, if any, between G3EC (n = 61) and USC (n = 47) on a total of 565 patients with endometrial cancer. In addition, meta-analysis was performed using data from seven previous publications (n = 8,637) and from the Asan Medical Center (n = 108). Regarding the cases from our institution, USC tended to occur in older patients (≥65 years) than G3EC (P = 0.011). Deep myometrial invasion (more than or equal to half) was more frequently identified in G3EC (36/61, 59.0 %) than in USC (17/47, 36.2 %) (P = 0.021). Between patients with early stage G3EC and USC (stages I and II), there were no significant differences in any clinicopathological parameter, but there was a significant difference in overall survival (P = 0.017) that was not found in advanced stage (P = 0.588). USC was an independent prognostic factor for poor overall survival (hazard ratio, 6.125; P = 0.030) in early stage patients. In the meta-analysis on 5-year survival in patients with early stage cancers, which also included our study results, a higher relative risk (1.92, 95 % CI 1.62-2.27) was demonstrated in USC than in G3EC (P < 0.001). In conclusion, our study reveals that USC is associated with a poorer prognosis compared with G3EC, only in patients with early stage carcinoma, suggesting that different treatment strategies should be considered according to the histologic type in order to improve treatment outcome.

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent. The imaging features of abdominal and pelvic sarcomas and abdominal wall sarcomas can be nonspecific and overlap with more common pathologic conditions, making diagnosis difficult or, in some cases, delaying diagnosis. Liposarcoma (well-differentiated and dedifferentiated liposarcomas), leiomyosarcoma, and gastrointestinal stromal tumor (GIST) are the most common intra-abdominal primary sarcomas. Any soft-tissue sarcoma can arise in the abdominal wall. Knowledge of the classification and pathologic features of soft-tissue sarcomas, the anatomic locations where they occur, and their cross-sectional imaging features helps the radiologist establish the diagnosis or differential diagnosis so that patients with soft-tissue sarcomas can receive optimal treatment and management. In part 1 of this article, the most common soft-tissue sarcomas (liposarcoma, leiomyosarcoma, and GIST) are reviewed, with a discussion on anatomic locations, classification, clinical considerations, and differential diagnosis. Part 2 will focus on the remainder of the soft-tissue sarcomas occurring in the abdomen and pelvis.

The objective of this article is to comprehensively review the scientific literature and summarize the available data regarding the outcome disparities of African American women with uterine cancer. Literature on disparities in uterine cancer was systematically reviewed using the PubMed search engine. Articles from 1992 to 2012 written in English were reviewed. Search terms included endometrial cancer, uterine cancer, racial disparities, and African American. Twenty-four original research articles with a total of 366,299 cases of endometrial cancer (337,597 Caucasian and 28,702 African American) were included. Compared to Caucasian women, African American women comprise 7% of new endometrial cancer cases, while accounting for approximately 14% of endometrial cancer deaths. They are diagnosed with later stage, higher-grade disease, and poorer prognostic histologic types compared to their Caucasian counterparts. They also suffer worse outcomes at every stage, grade, and for every histologic type. The cause of increased mortality is multifactorial. African American and white women have varying incidence of comorbid conditions, genetic susceptibility to malignancy, access to care and health coverage, and socioeconomic status; however, the most consistent contributors to incidence and mortality disparities are histology and socioeconomics. More robust genetic and molecular profile studies are in development to further explain histologic differences. Current studies suggest that histologic and socioeconomic factors explain much of the disparity in endometrial cancer incidence and mortality between white and African American patients. Treatment factors likely contributed historically to differences in mortality; however, studies suggest most women now receive equal care. Molecular differences may be an important factor to explain the racial inequities. Coupled with a sustained commitment to increasing access to appropriate care, on-going research in biologic mechanisms underlying histopathologic differences will help address and reduce the number of African American women who disproportionately suffer and die from endometrial malignancy.

Head and neck sarcomas are exceedingly rare and they include 4% - 10% of all sarcomas and less than 1% of all neoplasm of head and neck. The aim of this study is to evaluate the epidemiological characteristics of head and neck sarcomas of patients in Isfahan, Iran. In this retrospective study, from the 16000 patients whose files were evaluated, the total number of 105 head and neck sarcomas were collected. They were evaluated with due attention to age, gender of the patients and the most common location of the lesion. From the total number of 105 (0.6%) patients with sarcomas, 56 were men (53.33%) and 49 women (46.66%). The most common head and neck sarcomas among this population were Osteosarcoma (32 cases, 30.47%), Chondrosarcoma (14 cases, 13.33%), and Ewing sarcoma (11 cases, 10.47%).The most common soft tissue sarcoma was Rabdomiosarcoma. Mandible was the most common location for these lesions. In this study, the hard tissue sarcomas were more prevalent than soft tissue ones. Hence, special attention should be paid to the patients when being diagnosed.

Ewing's sarcoma is an aggressive malignancy of bone and soft tissue with high incidence of metastasis and resistance to chemotherapy. Cytochrome P450 (CYP) monooxygenases are a family of enzymes that are involved in the metabolism of exogenous and endogenous compounds, including anti-cancer drugs, and have been implicated in the aggressive behaviour of various malignancies. Tumour samples and clinical information including age, sex, tumour site, tumour size, clinical stage and survival were collected from 36 adult and paediatric patients with Ewing's sarcoma family tumours. Tissue microarrays slides were processed for immunohistochemical labelling for CYP3A4, CYP3A5 and CYP3A7 using liver sections as positive control. The intensity of staining was scored as negative, low or high expression and was analysed statistically for any association with patients' clinical information. Four cases were later excluded due to inadequate viable tissue. CYP3A4 staining was present in 26 (81%) cases with high expression noted in 13 (40%) of 32 cases. High expression was significantly associated with distant metastases (P < 0.05). CYP3A5 and CYP3A7 were expressed in 5 and 13 cases respectively (15.6%, 40.6%). There was no association between the expression of CYP3A isoforms and age, sex, tumour size, or location (pelvic or extra-pelvic). None of the biomarkers showed any correlation with overall or disease-free survival. In conclusion, expression of CYP3A isoforms is noted in Ewing's sarcoma tumours and high CYP3A4 expression may be associated with metastasis. Additional studies are needed to further investigate the role of CYP3A4 in the prognosis of these tumours. © 2015 The Authors.

There are limited data regarding the molecular characterization of undifferentiated pleomorphic sarcomas (UPS; formerly malignant fibrous histiocytoma). This study aimed to investigate the utility of next generation sequencing (NGS) in UPS to identify subsets of patients who harbour actionable mutations. Patients diagnosed with UPS underwent pathological re-evaluation by a pathologist specializing in sarcoma. Tumor DNA was isolated from archived fresh frozen tissue samples and genotyped using NGS with the Illumina MiSeq TruSeq Amplicon Cancer Panel (48 genes, 212 amplicons). In total, 95 patients initially classified with UPS were identified. Following pathology re-review the histological subtypes were reclassified to include: Myxofibrosarcoma (MFS, N = 44); UPS(N = 18); and Others (N = 27; including undifferentiated spindle cell sarcoma (N = 15) and dedifferentiated liposarcoma (N = 6)). Seven cases were excluded from further analysis for other reasons. Baseline demographics of the finalized cohort (N = 88) showed a median age of 66 years (32-95), primarily with stage I-III disease (92%) and high-grade (86%) lesions. Somatic mutations were identified in 31 cases (35%)(Total mutations = 36: solitary mutation(n = 27); two mutations( =n = 3); three mutations(n = 1)). The most commonly identified mutations were in TP53 (n = 24), ATM (n = 3) and PIK3CA (n = 2). Three of 43 patients with MFS and one of 18 patients with UPS had clinically relevant mutations, mainly related to biomarkers of prediction of response; however few had targetable driver mutations. Somatic mutation status did not influence disease free or overall survival. Based on the small number of clinically relevant mutations, these data do not support the routine use of targeted NGS panels outside of research protocols in UPS. © 2017 UICC.

Aim The aim of this retrospective study was to determine whether glucose metabolism assessed by using Fluorine-18 (F-18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) provides prognostic information independent of established prognostic factors in patients with Ewing sarcoma. Methods We retrospectively reviewed the medical records of 34 patients (men, 19; women, 15; mean age, 14.5 ± 9.7 years) with pathologically proven Ewing sarcoma. They had undergone F-18 FDG PET/CT as part of a pretreatment workup between September 2006 and April 2012. In this analysis, patients were classified by age, sex, initial location, size, and maximum standardized uptake value (SUVmax). The relationship between FDG uptake and survival was analyzed using the Kaplan-Meier method with the log-rank test and Cox’s proportional hazards regression model. Results The median survival time for all 34 subjects was 999 days and the median SUV by using PET/CT was 5.8 (range, 2–18.1). Patients with a SUVmax ≤ 5.8 survived significantly longer than those with a SUVmax > 5.8 (median survival time, 1265 vs. 656 days; p = 0.002). Survival was also found to be significantly related to age (p = 0.024), size (p = 0.03), and initial tumor location (p = 0.036). Multivariate analysis revealed that a higher SUVmax (p = 0.003; confidence interval [CI], 3.63–508.26; hazard ratio [HR], 42.98), older age (p = 0.023; CI, 1.34–54.80; HR, 8.59), and higher stage (p = 0.03; CI, 1.21–43.95; HR, 7.3) were associated with worse overall survival. Conclusions SUVmax measured by pretreatment F-18-FDG PET/CT can predict overall survival in patients with Ewing sarcoma. PMID:27100297

Can taxanes provide benefit in patients with CNS tumors and in pediatric patients with tumors? An update on the preclinical development of cabazitaxel.

While first-generation taxanes are valuable treatment options for many solid tumors, they are limited by an inability to cross the blood-brain barrier (BBB) and by limited efficacy in pediatric patients. Following promising preclinical data for the next-generation taxane cabazitaxel, including activity in tumor models fully sensitive, poorly sensitive or insensitive to docetaxel, and its ability to cross the BBB, further preclinical studies of cabazitaxel relevant to these two clinical indications were performed. Cabazitaxel brain distribution was assessed in mice, rats and dogs. Cabazitaxel antitumor activity was assessed in mice bearing intracranial human glioblastoma (SF295; U251) xenografts, and subcutaneous cell line-derived human pediatric sarcoma (rhabdomyosarcoma RH-30; Ewing's sarcoma TC-71 and SK-ES-1) or patient-derived pediatric sarcoma (osteosarcoma DM77 and DM113; Ewing's sarcoma DM101) xenografts. The activity of cabazitaxel-cisplatin combination was evaluated in BALB/C mice bearing the syngeneic murine colon adenocarcinoma, C51. Cabazitaxel penetrated rapidly in the brain, with a similar brain-blood radioactivity exposure relationship across different animal species. In intracranial human glioblastoma models, cabazitaxel demonstrated superior activity to docetaxel both at early (before BBB disruption) and at advanced stages, consistent with enhanced brain penetration. Compared with similar dose levels of docetaxel, cabazitaxel induced significantly greater tumor growth inhibition across six pediatric tumor models and more tumor regressions in five of the six models. Therapeutic synergism was observed between cisplatin and cabazitaxel, regardless of administration sequence. These preclinical data suggest that cabazitaxel could be an effective therapy in CNS and pediatric tumors, supporting ongoing clinical evaluation in these indications.

To describe the response rate and survival of children and adolescents with unresected or metastatic nonrhabdomyosarcomatous soft tissue sarcomas (NRSTS) treated with vincristine, ifosfamide, and doxorubicin. Between September 1996 and June 2000, 39 eligible patients received vincristine (1.5 mg/m(2) weekly for 13 doses), ifosfamide (3 g/m(2) daily for 3 days every 3 weeks for seven cycles), doxorubicin (30 mg/m(2) daily for 2 days for six cycles), and mesna (750 mg/m(2) for four doses after ifosfamide). Granulocyte colony-stimulating factor was administered daily (5 mug/kg) after each cycle of chemotherapy. Radiotherapy was administered from weeks 7 through 12. The median patient age at diagnosis was 11.7 years; the most common primary tumor site was lower extremity (36%); and synovial sarcoma was the predominant histology. More than three fourths of all tumors were 5 cm or greater at their largest diameters. The overall objective combined partial and complete response rate was 41% (95% CI, 25.7% to 56.7%). The estimated 3-year overall survival and progression-free survival rates (+/- standard deviation) for eligible patients were 59% +/- 8.2% and 43.6% +/- 7%, respectively. Patients with clinical group III disease had significantly better 3-year and progression-free survival rates compared with patients who presented with metastatic disease. The vincristine, ifosfamide, and doxorubicin regimen was moderately active against pediatric NRSTS. Patients with synovial sarcoma had higher response rates than other patients, and patients with unresected disease had improved outcomes. Patients with metastatic disease continue to fare poorly, and newer approaches are indicated for these patients.

Prognosis and delay of diagnosis among Kaposi’s sarcoma patients in Uganda: a cross-sectional study

PubMed Central

2014-01-01

Background In low- and middle-income countries, the association between delay to treatment and prognosis for Kaposi’s sarcoma (KS) patients is yet to be studied. Methods This is a prospective study of HIV-infected adults with histologically-confirmed KS treated at the Uganda Cancer Institute (UCI). Standardized interviews were conducted in English or Luganda. Medical records were abstracted for KS stage at admission to UCI. Multivariable logistic regression assessed relationships between diagnostic delay and stage at diagnosis. Results Of 161 patients (90% response rate), 69% were men, and the mean age was 34.0 years (SD 7.7). 26% had been seen in an HIV clinic within 3 months, 72% were on antiretroviral therapy, and 26% had visited a traditional healer prior to diagnosis. 45% delayed seeking care at UCI for ≥3 months from symptom onset. Among those who delayed, 36% waited 6 months, and 25% waited 12 months. Common reasons for delay were lack of pain (48%), no money (32%), and distance to UCI (8%). In adjusted analysis patients who experienced diagnostic delay were more likely than those who did not delay to have poor-risk KS stage (OR 3.41, p = 0.002, 95% CI: 1.46-7.45). In adjusted analyses visiting a traditional healer was the only variable associated with greater likelihood of delay (OR 2.69, p = 0.020, 95% CI: 1.17-6.17). Conclusions Diagnostic delay was associated with poor-risk stage at diagnosis, and visiting a traditional healer was associated with higher odds of delay. The relationship between traditional and Western medicine presents a critical intervention point to improve KS-related outcomes in Uganda. PMID:24904686

Well-defined poly(ethylene glycol)-b-allyl functional polylactide-b-polylactides (PEG-APLA-PLAs) are synthesized through sequential ring-opening polymerization. PEG-APLA-PLAs that have amphiphilic properties and reactive allyl side chains on their intermediate blocks are successfully transferred to core-shell interface cross-linked micelles (ICMs) by micellization and UV-initiated irradiation. ICMs have demonstrated enhanced colloidal stability in physiological-mimicking media. Hydrophobic molecules such as Nile Red or doxorubicin (Dox) are readily loaded into ICMs; the resulting drug-ICM formulations possess slow and sustained drug release profiles under physiological-mimicking conditions. ICMs exhibit negligible cytotoxicity in human uterine sarcoma cancer cells by using biodegradable aliphatic polyester as the hydrophobic segments. Relative to free Dox, Dox-loaded ICMs show a reduced cytotoxicity due to the late intracellular release of Dox from ICMs. Overall, ICMs represent a new type of biodegradable cross-linked micelle and can be employed as a promising platform for delivering a broad variety of hydrophobic drugs. © 2016 WILEY-VCH Verlag GmbH & Co.

Fine-needle aspiration (FNA) is routinely used to evaluate primary thyroid lesions (PTLs), however, its role in diagnosing secondary thyroid neoplasms (STNs) has not been extensively studied. The goal was to examine the clinical and cytopathologic features of STNs diagnosed on FNA. The clinico-pathologic features of 28 STNs were analyzed. All PTLs, lymphomas, and locally invasive tumors were excluded. There were 28 STNs (0.18% incidence) out of 15,800 thyroid FNAs (12 males, 16 females, 32 - 85 years), all occurring metachronously (3 weeks-20 years, average 78.3 months) comprising 24 (85.7%) metastatic carcinomas (14 [50%] renal; 4 [14.3%] head and neck squamous cell carcinomas, 3 [10.7%] breast, and 1 [3.6%] colorectal, uterine serous carcinoma, and lung adenosquamous carcinoma, respectively), 3 sarcomas (10.7%) and 1 melanoma (3.6%). STNs are rare and diverse tumors which may occur decades after primary malignancy. Renal carcinomas are the most common. Prior history of malignancy, high index of suspicion, and attention to key distinguishing cytologic clues are critical for accurate diagnosis. © 2015 Wiley Periodicals, Inc.

1997-06-01

The aim of the study was to assess the relationship between fallopian tube lavage cytology and recognized microscopic prognostic features in cancer of the uterine corpus. Tubal (TW) and peritoneal washing cytology (PW), endometrial tumor grade, and tumor involvement of the cervix, myometrium, myometrial vessels, and peritoneum were assessed in 150 patients. Endometrioid adenocarcinoma grade I was considered a low-grade tumor, while endometrioid carcinoma grades 2/3, serous/clear cell carcinoma, carcinosarcoma, and high-grade stromal sarcoma were considered high grade. The overall concordance rate for paired TWs and PWs was 72% (108/150). Forward stepwise logistic regression analysis of the 150 tumors revealed that only PWs and cervical involvement were independently predictive of TWs. No relationship was evident between TWs and depth of myometrial invasion, myometrial vascular involvement, or peritoneal metastases. It is concluded that retrograde transtubal spread by malignant endometrial cells occurs independently of myometrial histoprognostic features. TWs provide supporting evidence for diagnostically difficult PWs, and malignant TWs may be detected in the presence of minimally invasive serous/clear cell carcinoma and carcinosarcoma of the endometrium.

Patients with advanced sarcomas have a poor prognosis and few treatment options that improve overall survival. Chemotherapy and targeted therapies offer short-lived disease control. We assessed pembrolizumab, an anti-PD-1 antibody, for safety and activity in patients with advanced soft-tissue sarcoma or bone sarcoma. In this two-cohort, single-arm, open-label, phase 2 study, we enrolled patients with soft-tissue sarcoma or bone sarcoma from 12 academic centres in the USA that were members of the Sarcoma Alliance for Research through Collaboration (SARC). Patients with soft-tissue sarcoma had to be aged 18 years or older to enrol; patients with bone sarcoma could enrol if they were aged 12 years or older. Patients had histological evidence of metastatic or surgically unresectable locally advanced sarcoma, had received up to three previous lines of systemic anticancer therapy, had at least one measurable lesion according to the Response Evaluation Criteria In Solid Tumors version 1.1, and had at least one lesion accessible for biopsy. All patients were treated with 200 mg intravenous pembrolizumab every 3 weeks. The primary endpoint was investigator-assessed objective response. Patients who received at least one dose of pembrolizumab were included in the safety analysis and patients who progressed or reached at least one scan assessment were included in the activity analysis. Accrual is ongoing in some disease cohorts. This trial is registered with ClinicalTrials.gov, number NCT02301039. Between March 13, 2015, and Feb 18, 2016, we enrolled 86 patients, 84 of whom received pembrolizumab (42 in each disease cohort) and 80 of whom were evaluable for response (40 in each disease cohort). Median follow-up was 17·8 months (IQR 12·3-19·3). Seven (18%) of 40 patients with soft-tissue sarcoma had an objective response, including four (40%) of ten patients with undifferentiated pleomorphic sarcoma, two (20%) of ten patients with liposarcoma, and one (10%) of ten patients with synovial sarcoma. No patients with leiomyosarcoma (n=10) had an objective response. Two (5%) of 40 patients with bone sarcoma had an objective response, including one (5%) of 22 patients with osteosarcoma and one (20%) of five patients with chondrosarcoma. None of the 13 patients with Ewing's sarcoma had an objective response. The most frequent grade 3 or worse adverse events were anaemia (six [14%]), decreased lymphocyte count (five [12%]), prolonged activated partial thromboplastin time (four [10%]), and decreased platelet count (three [7%]) in the bone sarcoma group, and anaemia, decreased lymphocyte count, and prolonged activated partial thromboplastin time in the soft-tissue sarcoma group (three [7%] each). Nine (11%) patients (five [12%] in the bone sarcoma group and four [10%] in the soft-tissue sarcoma group) had treatment-emergent serious adverse events (SAEs), five of whom had immune-related SAEs, including two with adrenal insufficiency, two with pneumonitis, and one with nephritis. The primary endpoint of overall response was not met for either cohort. However, pembrolizumab showed encouraging activity in patients with undifferentiated pleomorphic sarcoma or dedifferentiated liposarcoma. Enrolment to expanded cohorts of those subtypes is ongoing to confirm and characterise the activity of pembrolizumab.

To investigate the impact of pelvic radiation on survival in patients with uterine clear cell carcinoma (UCC) who received adjuvant chemotherapy. Patients with stage I-IV UCC who had undergone surgery and chemotherapy were identified from the Surveillance, Epidemiology, and End Results (SEER) programm 2000-2009. Patients were divided into those who received only chemotherapy and those who received both chemotherapy and radiation therapy. Kaplan-Meier curves and Cox regression models were used for analysis. Of the 317 patients included, 195 (62%) were in the chemotherapy only group and 122 (38%) were in the chemotherapy and radiation therapy group. Pelvic radiation was associated with significant improvement in overall survival (median 88 versus 25 months, 5 year survival: 58% versus 33%, P<0.001) in the chemotherapy and radiation therapy group compared with the chemotherapy only group for the entire cohort. On subset analysis, chemotherapy and radiation therapy was associated with improved overall survival in late stage disease (III-IV) (5 year 54% versus 22%, P<0.001) compared with the chemotherapy only group, whereas in stage I-II UCC, there was no difference in overall survival between the chemotherapy and radiotherapy group and the chemotherapy only group (5 year 65% versus 67%, P=0.69). In multivariable analysis, pelvic radiation was associated with improved survival in patients with late stage disease (hazard ratio 0.57, 95% confidence interval 0.35-0.94, P=0.03) but not for early stage disease (hazard ratio 0.81, 95% confidence interval 0.33-2.0, P=0.65). Other significant predictors were advanced stage, positive cytology and extensive lymphadenectomy. Radiation was associated with significant improvement in survival in advanced stage UCC, but not in early stage UCC. These data support the beneficial role of radiation therapy in UCC, especially in patients with advanced stage disease. Copyright © 2016 The Royal College of Radiologists. Published by Elsevier Ltd.

Background: Head and neck sarcomas are exceedingly rare and they include 4% - 10% of all sarcomas and less than 1% of all neoplasm of head and neck. Objectives: The aim of this study is to evaluate the epidemiological characteristics of head and neck sarcomas of patients in Isfahan, Iran. Patients and Methods: In this retrospective study, from the 16000 patients whose files were evaluated, the total number of 105 head and neck sarcomas were collected. They were evaluated with due attention to age, gender of the patients and the most common location of the lesion. Results: From the total number of 105 (0.6%) patients with sarcomas, 56 were men (53.33%) and 49 women (46.66%). The most common head and neck sarcomas among this population were Osteosarcoma (32 cases, 30.47%), Chondrosarcoma (14 cases, 13.33%), and Ewing sarcoma (11 cases, 10.47%).The most common soft tissue sarcoma was Rabdomiosarcoma. Mandible was the most common location for these lesions. Conclusions: In this study, the hard tissue sarcomas were more prevalent than soft tissue ones. Hence, special attention should be paid to the patients when being diagnosed. PMID:26478791

Studying progression of congenital diseases in animal models can greatly benefit from live embryonic imaging Mouse have long served as a model of mammalian embryonic developmental processes, however, due to intra-uterine nature of mammalian development live imaging is challenging. In this report we present results on live mouse embryonic imaging in utero with Optical Coherence Tomography. Embryos from 12.5 through 17.5 days post-coitus (dpc) were studied through the uterine wall. In longitudinal studies, same embryos were imaged at developmental stages 13.5, 15.5 and 17.5 dpc. This study suggests that OCT can serve as a powerful tool for live mouse embryo imaging. Potentially this technique can contribute to our understanding developmental abnormalities associated with mutations, toxic drugs.

Background: Uterine leiomyoma (UL) is a benign tumor of uterine smooth muscle that affects women in reproductive ages. FAS has an important role in initial stages of apoptosis. Previous studies have shown an association between the FAS gene and tumorigenesis. In the present study, we evaluated the relationship between FAS A-670G (rs 1800682) and UL risk Methods: The FAS gene polymorphism of 155 women with UL and 157 healthy controls was analyzed by the polymerase chain reaction restriction fragment length polymorphism method Results: The AA, AG, and GG genotype frequencies of the FAS A-670G polymorphism were respectively 37.4, 42.6, and 20% in women with UL, and 46, 42.6, and 11.5% in healthy controls. The risk of UL in women was 1.5-fold greater in GG-genotype women than in AA-genotype women. The G allele frequencies were 41% in women with UL and 33% in healthy controls and statistically different (P = 0.03) Conclusion: The FAS polymorphism was associated with the risk of UL in a sample of Iranian women.

1. Pronounced cases of Barlow's disease may be produced in the fetus as early as ten to fifteen days after the commencement of dieting pregnant guinea pigs with oats and water. There are wide individual variations. The scorbutic changes in the skeleton are greatest in the earlier embryonic stages. The fetuses of that period, with practically no exceptions, die and show marked traces of impeded growth. 2. Fetuses from the later period of pregnancy are born alive, and apparently fully developed, with comparatively slight changes in the osseous system. 3. Even a short extension of the period of extra-uterine dieting on milk from scorbutic mothers and later on oats and water is sufficient to change the latent scurvy into a highly pronounced case. 4. The fetus cannot be kept alive longer than the adult animal, about twenty-eight days, either by intra-uterine dieting alone or by combined intra- and extra-uterine dieting. 5. The mothers show signs of disease at an early period, and are more severely attacked than non-pregnant animals. Death also occurs comparatively often in the first period of gestation.

Altered progesterone responsiveness leads to female infertility and cancer, but underlying mechanisms remain unclear. Mice with uterine-specific ablation of GATA binding protein 2 (Gata2) are infertile, showing failures in embryo implantation, endometrial decidualization, and uninhibited estrogen signaling. Gata2 deficiency results in reduced progesterone receptor (PGR) expression and attenuated progesterone signaling, as evidenced by genome-wide expression profiling and chromatin immunoprecipitation. GATA2 not only occupies at and promotes expression of the Pgr gene but also regulates downstream progesterone responsive genes in conjunction with the PGR. Additionally, Gata2 knockout uteri exhibit abnormal luminal epithelia with ectopic TRP63 expressing squamous cells and a cancer-related molecular profile in a progesterone-independent manner. Lastly, we found a conserved GATA2-PGR regulatory network in both human and mice based on gene signature and path analyses using gene expression profiles of human endometrial tissues. In conclusion, uterine Gata2 regulates a key regulatory network of gene expression for progesterone signaling at the early pregnancy stage. Published by Elsevier Inc.

Radiation therapy is one of the effective curative treatments for uterine cervical cancer. However poor clinical results for the advanced stages require further improvement of the treatment. Intensive studies on basic and clinical research have been made to improve local control, primarily important for long term survival in radiation therapy. Regarding current advancement in radiation therapy for uterine cervical cancer, the following three major subjects are pointed out; technological development to improve dose distribution by image guided radiation therapy technology, the concomitant anticancer chemotherapy with combination of radiation therapy, and radiation biological assessment of the radiation resistance of tumors. The biological factors overviewed in this article include hypoxia relating factors of HIF-1alpha, SOD, cell cycle parameters of pMI, proliferation factors of Ki67, EGFR, cerbB2, COX-2, cycle regulation proteins p53, p21, apoptosis regulation proteins Bcl2 and Bax and so on. Especially, the variety of these radiation biological factors is important for the selection of an effective treatment method for each patient to maximize the treatment benefit.

Retrospective analysis of presentation, diagnosis and outcome of patients with osteosarcoma, chondrosarcoma and Ewing's sarcoma was performed for a single Sarcoma Center in Zurich at the University Hospital Balgrist. 201 patients were included. Overall survival at five and ten years were 74 ± 6%, 69 ± 7% for osteosarcoma (n = 85, since 2000), 85 ± 7%, 80 ± 9% for Ewing's sarcoma (n = 43, since 1990) and 86 ± 5%, 78 ± 9% for chondrosarcoma (n = 73, since 2000). The here presented overall survival rates from a single Sarcoma Center in Switzerland appear to be equivalent to other large international monocenter studies. The presentation and epidemiology of these patients are in accordance with large multicenter epidemiological studies. A nationwide sarcoma database (SwissSARCOS; www.sarcoma.ch) seems indispensable for more detailed analysis and quality management in such rare diseases.

The aim of this study was to determine the quality of intrapartum uterine activity (UA) monitoring in daily practice during the first and second stages of labour. The total duration of inadequate UA monitoring is quantified in relation to the technique applied, namely, external tocodynamometry (TOCO) or electrohysterography (EHG). 144 UA recordings, collected from 1st September 2008 until 15th October 2009 from deliveries at the Marien-Hospital Witten, Germany, were analysed by obstetricians based at different centres. The included recordings were from singleton and simultaneously with external TOCO and EHG monitored pregnancies. External TOCO and EHG UA recordings were blinded. The percentages of "adequate" UA recordings in the first and second stages of labour were much higher for the external EHG than the external TOCO mode (p<0.001). All doctors evaluated the UA assessment as "easier" (p <0.001) using the EHG compared with TOCO. Intrapartum UA monitoring in -daily practice via the EHG mode provides a more recognisable UA trace than the TOCO. © Georg Thieme Verlag KG Stuttgart · New York.

Purpose The outcome for patients with metastatic or recurrent sarcoma remains poor. Adoptive therapy with tumor-directed T cells is an attractive therapeutic option but has never been evaluated in sarcoma. Patients and Methods We conducted a phase I/II clinical study in which patients with recurrent/refractory human epidermal growth factor receptor 2 (HER2) –positive sarcoma received escalating doses (1 × 104/m2 to 1 × 108/m2) of T cells expressing an HER2-specific chimeric antigen receptor with a CD28.ζ signaling domain (HER2-CAR T cells). Results We enrolled 19 patients with HER2-positive tumors (16 osteosarcomas, one Ewing sarcoma, one primitive neuroectodermal tumor, and one desmoplastic small round cell tumor). HER2-CAR T-cell infusions were well tolerated with no dose-limiting toxicity. At dose level 3 (1 × 105/m2) and above, we detected HER2-CAR T cells 3 hours after infusion by quantitative polymerase chain reaction in 14 of 16 patients. HER2-CAR T cells persisted for at least 6 weeks in seven of the nine evaluable patients who received greater than 1 × 106/m2 HER2-CAR T cells (P = .005). HER2-CAR T cells were detected at tumor sites of two of two patients examined. Of 17 evaluable patients, four had stable disease for 12 weeks to 14 months. Three of these patients had their tumor removed, with one showing ≥ 90% necrosis. The median overall survival of all 19 infused patients was 10.3 months (range, 5.1 to 29.1 months). Conclusion This first evaluation of the safety and efficacy of HER2-CAR T cells in patients with cancer shows the cells can persist for 6 weeks without evident toxicities, setting the stage for studies that combine HER2-CAR T cells with other immunomodulatory approaches to enhance their expansion and persistence.

Since November 1981, when pion irradiation was introduced for deep seated tumors at the Swiss Institute for Nuclear Research (SIN, now Paul Scherrer Institute, PSI) a dynamic, 3-dimensional spot scan treatment technique has been in use. To exploit this technique a special optimization treatment planning system has been designed. Of a total of 331 patients treated with pions from November 1981-December 1987, 35 were irradiated for unresectable soft tissue sarcomas. In 32/35 patients, tumor sites were retroperitoneal, pelvic or in the groin or thigh. Twenty-nine tumors had a maximum diameter of greater than 10 cm, 18 tumors of greater than 15 cm; 30 tumors had grade 2/3 and 32 Stage III B/IV A/IV B. Eight of 35 patients received a low pion total dose, 7-27 Gy. Twenty-seven patients received a total dose of 30-36 Gy, fraction size 150-170 cGy (90%-isodose), 20 fractions, 4 times per week. Of these 27 patients, severe late reactions appeared in five: 2/8 patients with extremity/groin sarcomas (1/2 caused by biopsy) and 3/19 patients with retroperitoneal/pelvic sarcomas (one a skin reaction after Actinomycin-D, one a small bowel reaction after 36 Gy, a dose no longer used). Seven of 27 patients had metastases at the beginning of irradiation. Three of 27 were treated with excisional biopsy, 9 with incisional biopsy or partial resection and in 15 patients biopsies were performed for histology only. The median follow-up of these 27 patients was 17 months (5-66). There was no progression in eight extremity/groin tumors but in 4 of 19 retroperitoneal/pelvic tumors. Three of these were marginal progressions. The actuarial 5-year rate of local tumor control is 64%; the actuarial 5-year survival rate of patients without metastases at the beginning of treatment is 58%. Dynamic spot scan pion irradiation proves to be a successful treatment technique for unresectable sarcomas with a high rate of tumor control and a very low rate of severe late reactions.

We conducted a phase I/II clinical study in which patients with recurrent/refractory human epidermal growth factor receptor 2 (HER2) -positive sarcoma received escalating doses (1 × 10(4)/m(2) to 1 × 10(8)/m(2)) of T cells expressing an HER2-specific chimeric antigen receptor with a CD28.ζ signaling domain (HER2-CAR T cells). We enrolled 19 patients with HER2-positive tumors (16 osteosarcomas, one Ewing sarcoma, one primitive neuroectodermal tumor, and one desmoplastic small round cell tumor). HER2-CAR T-cell infusions were well tolerated with no dose-limiting toxicity. At dose level 3 (1 × 10(5)/m(2)) and above, we detected HER2-CAR T cells 3 hours after infusion by quantitative polymerase chain reaction in 14 of 16 patients. HER2-CAR T cells persisted for at least 6 weeks in seven of the nine evaluable patients who received greater than 1 × 10(6)/m(2) HER2-CAR T cells (P = .005). HER2-CAR T cells were detected at tumor sites of two of two patients examined. Of 17 evaluable patients, four had stable disease for 12 weeks to 14 months. Three of these patients had their tumor removed, with one showing ≥ 90% necrosis. The median overall survival of all 19 infused patients was 10.3 months (range, 5.1 to 29.1 months). This first evaluation of the safety and efficacy of HER2-CAR T cells in patients with cancer shows the cells can persist for 6 weeks without evident toxicities, setting the stage for studies that combine HER2-CAR T cells with other immunomodulatory approaches to enhance their expansion and persistence. © 2015 by American Society of Clinical Oncology.

Accumulation of the DNA/RNA binding protein fused in sarcoma as cytoplasmic inclusions in neurons and glial cells is the pathological hallmark of all patients with amyotrophic lateral sclerosis with mutations in FUS as well as in several subtypes of frontotemporal lobar degeneration, which are not associated with FUS mutations. The mechanisms leading to inclusion formation and fused in sarcoma-associated neurodegeneration are only poorly understood. Because fused in sarcoma belongs to a family of proteins known as FET, which also includes Ewing's sarcoma and TATA-binding protein-associated factor 15, we investigated the potential involvement of these other FET protein family members in the pathogenesis of fused in sarcoma proteinopathies. Immunohistochemical analysis of FET proteins revealed a striking difference among the various conditions, with pathology in amyotrophic lateral sclerosis with FUS mutations being labelled exclusively for fused in sarcoma, whereas fused in sarcoma-positive inclusions in subtypes of frontotemporal lobar degeneration also consistently immunostained for TATA-binding protein-associated factor 15 and variably for Ewing's sarcoma. Immunoblot analysis of proteins extracted from post-mortem tissue of frontotemporal lobar degeneration with fused in sarcoma pathology demonstrated a relative shift of all FET proteins towards insoluble protein fractions, while genetic analysis of the TATA-binding protein-associated factor 15 and Ewing's sarcoma gene did not identify any pathogenic variants. Cell culture experiments replicated the findings of amyotrophic lateral sclerosis with FUS mutations by confirming the absence of TATA-binding protein-associated factor 15 and Ewing's sarcoma alterations upon expression of mutant fused in sarcoma. In contrast, all endogenous FET proteins were recruited into cytoplasmic stress granules upon general inhibition of Transportin-mediated nuclear import, mimicking the findings in frontotemporal lobar degeneration with fused in sarcoma pathology. These results allow a separation of fused in sarcoma proteinopathies caused by FUS mutations from those without a known genetic cause based on neuropathological features. More importantly, our data imply different pathological processes underlying inclusion formation and cell death between both conditions; the pathogenesis in amyotrophic lateral sclerosis with FUS mutations appears to be more restricted to dysfunction of fused in sarcoma, while a more global and complex dysregulation of all FET proteins is involved in the subtypes of frontotemporal lobar degeneration with fused in sarcoma pathology.

A review of soft-tissue sarcomas: translation of biological advances into treatment measures

Soft-tissue sarcomas are rare malignant tumors arising from connective tissues and have an overall incidence of about five per 100,000 per year. While this diverse family of malignancies comprises over 100 histological subtypes and many molecular aberrations are prevalent within specific sarcomas, very few are therapeutically targeted. Instead of utilizing molecular signatures, first-line sarcoma treatment options are still limited to traditional surgery and chemotherapy, and many of the latter remain largely ineffective and are plagued by disease resistance. Currently, the mechanism of sarcoma oncogenesis remains largely unknown, thus necessitating a better understanding of pathogenesis. Although substantial progress has not occurred with molecularly targeted therapies over the past 30 years, increased knowledge about sarcoma biology could lead to new and more effective treatment strategies to move the field forward. Here, we discuss biological advances in the core molecular determinants in some of the most common soft-tissue sarcomas – liposarcoma, angiosarcoma, leiomyosarcoma, rhabdomyosarcoma, Ewing’s sarcoma, and synovial sarcoma – with an emphasis on emerging genomic and molecular pathway targets and immunotherapeutic treatment strategies to combat this confounding disease.

GOLLARD, RUSSELL P.; TURNER, J. FRANCIS

2012-01-01

Metastectomy or resection of sarcomas which have metastasized to the lung from other sites has a long and established history. At present, there are more than forty different drugs with activity in soft tissue sarcomas. A number of sarcomas demonstrate differential sensitivities to chemotherapy and targeted agents. Intimate knowledge of the biological behavior of each distinct type of sarcoma should predicate what treatment or protocol is most suitable. Certain patients might benefit from either neoadjuvant or adjuvant therapy following the resection of metastatic lesions. Much remains to be learned about the differential sensitivities of various sarcomas to different treatment regimens. PMID:23205068

Ewing's sarcoma of bone is a primary childhood malignancy of bone that is treated with X-radiation therapy in combination with surgical excision and chemotherapy. To better study Ewing's sarcoma of bone we developed a novel model of primary Ewing's sarcoma of bone and then treated animals with X-radiation therapy. We identified that uncontrolled tumor resulted in lytic bone destruction while X-radiation therapy decreased lytic bone destruction and increased limb-length asymmetry, a common, crippling complication of X-radiation therapy. Osteoclasts were indentified adjacent to the tumor, however, we were unable to detect RANK-ligand in the Ewing's tumor cells in vitro, which lead us to investigate alternate mechanisms for osteoclast formation. Ewing's sarcoma tumor cells and archival Ewing's sarcoma of bone tumor biopsy samples were shown to express MCSF, which could promote osteoclast formation. Increased monocyte numbers were detected in peripheral blood and spleen in animals with untreated Ewing's sarcoma tumor while monocyte number in animals treated with x-radiation had normal numbers of monocytes. Our data suggest that our Ewing's sarcoma of bone model will be useful in the study Ewing's sarcoma tumor progression in parallel with the effects of chemotherapy and X-radiation therapy.

To overview the status of gynecologic cancer in Indonesia. Information regarding Indonesia obtained from World Bank Report and Statistical Yearbook of Indonesia 2007, epidemiological data obtained from Histopathological Data of Cancer in Indonesia 2002, Department of Health-Registry Body of Indonesian Specialist of Pathology Association-Indonesian Cancer Society; Various Hospitals in big Cities in Indonesia. Indonesia is an Archipelago with a total area of 1,922,570.00 km(2), the population is 222,192,000 (2006), the fourth world rank. Female is 49.86% with life expectancy 69 years. Gross National Product per Capita is 690.00 USD. Histopathological report in 2002 revealed that cervical cancer, ovarian cancer and uterine cancer were the most frequent cancer among female, which were the first (2,532 cases), the third (829 cases) and the eighth (316 cases) rank respectively. The peak age for cervical, uterine and ovarian cancer was 45-54 years. HPV 16, 18 were found in 82% of invasive cervical. Data from various academic hospitals in 2007 showed that cervical cancer is the most common malignancy followed by ovary, uterus, vulva and vagina. Five-year survival rate of stage I, II, III, IV cervical cancer were 50%, 40%, 20%, and 0% respectively. Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rate are 94.3%, 75.0%, 31%, and 11.7% for stage I, II, III, and IV respectively. Five-year disease-free survival rate of endometrial cancer was 71.9%. Indonesia is the biggest Archipelago with a dense population but the income per capita still low (poor country). The most common gynecologic cancer is cervical cancer, followed by ovarian and uterine cancer. These cancers are included in top ten cancers in Indonesia. HPV 16, 18 were the most cause of cervical cancer. The five-year survival rates are comparable with world report.

Muscle segment homeobox genes direct embryonic diapause by limiting inflammation in the uterus

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cha, Jeeyeon; Burnum-Johnson, Kristin E.; Bartos, Amanda

Embryonic diapause (delayed implantation) is a reproductive strategy widespread in the animal kingdom. Under this condition, embryos at the blastocyst stage become dormant simultaneously with uterine quiescence until environmental or physiological conditions are favorable for the survival of the mother and newborn. Under favorable conditions, activation of the blastocyst and uterus ensues with implantation and progression of pregnancy. Although endocrine factors are known to participate in this process, the underlying molecular mechanism coordinating this phenomenon is not clearly understood. We recently found that uterine muscle segment homeobox (Msx) transcription factors are critical for the initiation and maintenance of delayed implantationmore » in mice. To better understand why Msx genes are critical for delayed implantation, we compared uterine proteomics profiles between littermate floxed (Msx1/Msx2f/f) mice and mice with uterine deletion of Msx genes (Msx1/Msx2d/d) under delayed conditions. In Msx1/Msx2d/d uteri, pathways including protein translation, ubiquitin-proteasome system, inflammation, chaperone-mediated protein folding, and endoplasmic reticulum (ER) stress were enriched, and computational modeling showed intersection of these pathways on inflammatory responses. Indeed, increases in the ubiquitin-proteasome system and inflammation conformed to proteotoxic and ER stress in Msx1/Msx2d/d uteri under delayed conditions. Interestingly, treatment with a proteasome inhibitor bortezomib further exacerbated ER stress in Msx1/Msx2d/d uteri with aggravated inflammatory response, deteriorating rate of blastocyst recovery and failure to sustain delayed implantation. This study highlights a previously unrecognized role for Msx in preventing proteotoxic stress and inflammatory responses to coordinate embryo dormancy and uterine quiescence during embryonic diapause.« less

Inhibition of CHK1 sensitizes Ewing sarcoma cells to the ribonucleotide reductase inhibitor gemcitabine

Ewing sarcoma is a bone and soft tissue sarcoma that occurs in children and young adults. The EWS-FLI1 gene fusion is the driver mutation in most Ewing sarcoma tumors and functions, in part, as an aberrant transcription factor. We recently identified that Ewing sarcoma cells are sensitive to inhibition of ribonucleotide reductase (RNR), which catalyzes the formation of deoxyribonucleotides from ribonucleotides. In this report, we show that Ewing sarcoma cells are sensitive to treatment with clofarabine, which is a nucleoside analogue and allosteric inhibitor of RNR. However, clofarabine is a reversible inhibitor of RNR and we found that the effect of clofarabine is limited when using a short (6-hour) drug treatment. Gemcitabine, on the other hand, is an irreversible inhibitor of the RRM1 subunit of RNR and this drug induces apoptosis in Ewing sarcoma cells when used in both 6-hour and longer drug treatments. Treatment of Ewing sarcoma cells with gemcitabine also results in activation of checkpoint kinase 1 (CHK1), which is a critical mediator of cell survival in the setting of impaired DNA replication. Notably, inhibition of CHK1 function in Ewing sarcoma cells using a small-molecule CHK1 inhibitor, or siRNA knockdown, in combination with gemcitabine results in increased toxicity both in vitro and in vivo in a mouse xenograft experiment. Overall, our results provide insight into Ewing sarcoma biology and identify a candidate therapeutic target, and drug combination, in Ewing sarcoma. PMID:29152060

More than half of all sarcomas occur in adolescents and young adults (AYAs) aged 15 to 39 years. After the publication of the AYA series in the April 1, 2016 issue of Cancer, several leaders in the field of sarcoma across disciplines gathered to discuss the status of sarcoma clinical research in AYAs. They determined that a focused effort to include the underrepresented and understudied AYA population in current and future sarcoma clinical trials is overdue. Trial enrichment for AYA-aged sarcoma patients will produce more meaningful results that better represent the disease's biology, epidemiology, and treatment environment. To address the current deficit, this commentary outlines changes believed to be necessary to expediently achieve an increase in the enrollment of AYAs in sarcoma clinical trials. PMID:28493547

2016-04-27

Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case.

CIC-DUX4 and BCOR-CCNB3 fusion-gene-associated small round cell sarcomas account for a proportion of pediatric small round cell sarcomas, but their pathological features have not been sufficiently clarified. We reviewed a large number of soft tissue tumors registered at our institution, retrieved the cases of unclassified tumors with a small round cell component, and subjected them to histopathological, immunohistochemical, and gene profile analysis. We reviewed 164 cases of unclassified tumors with a small round cell component and analyzed them by RT-PCR and FISH. Tumors positive for a specific fusion-gene were also subjected to histopathological and immunohistochemical examinations. We identified 16 cases of BCOR-CCNB3/CIC-associated (CIC-DUX4 or CIC gene rearrangement-positive) sarcomas. These included seven BCOR-CCNB3 sarcomas and nine CIC-associated sarcomas. Heterogeneous elements included a myxoid spindle cell component in three BCOR-CCNB3 sarcomas and an epithelioid cell component in two CIC-associated sarcomas (one CIC-DUX4-positive and one CIC-DUX4-negative sarcomas). Mitotic activity was low in both heterogeneous components. By immunohistochemistry, in seven BCOR-CCNB3 sarcomas expression of EMA was positive in two cases, of p63 in three, of CD56 in six, of TLE1 in seven, of NKX2.2 in two, of CCNB3 in seven, and of BCOR in six cases (one case could not be tested for BCOR). In nine cases of CIC-associated sarcoma, CD56 was expressed in five, alpha-smooth muscle actin in one, ERG in three, and CD99, WT1 and TLE1 each in eight cases. Both sarcoma types showed not only a small round cell component, but also a myxoid/epithelioid component with low mitotic activity.

Differential diagnosis of small round cell sarcomas (SRCSs) grouped under the Ewing sarcoma family of tumors (ESFT) can be a challenging situation for pathologists. Recent studies have revealed that some groups of Ewing-like sarcoma show typical ESFT morphology but lack any EWSR1-ETS gene fusions. Here we identified a novel gene fusion, CIC-FOXO4, in a case of Ewing-like sarcoma with a t(X;19)(q13;q13.3) translocation. The patient was a 63-year-old man who had an asymptomatic, 30-mm, well-demarcated, intramuscular mass in his right posterior neck, and imaging findings suggested a diagnosis of high-grade sarcoma. He was treated with complete resection and subsequent radiotherapy and chemotherapy. He was alive without local recurrence or distant metastasis 6 months after the operation. Histologic examination revealed SRCS with abundant desmoplastic fibrous stroma suggesting a desmoplastic small round cell tumor. Immunohistochemical analysis showed weak to moderate and partial staining for MIC2 (CD99) and WT1, respectively. High-throughput transcriptome sequencing revealed a gene fusion, and the genomic rearrangement between the CIC and FOXO4 genes was identified by fluorescence in situ hybridization. Aside from the desmoplastic stroma, the CIC-FOXO4 fusion sarcoma showed morphologic and immunohistochemical similarity to ESFT and Ewing-like sarcomas, including the recently described CIC-DUX4 fusion sarcoma. Although clinicopathologic analysis with additional cases is necessary, we conclude that CIC-FOXO4 fusion sarcoma is a new type of Ewing-like sarcoma that has a specific genetic signature. These findings have important implications for the differential diagnosis of SRCS.

Epithelial-type and neural-type cadherin expression in malignant noncarcinomatous neoplasms with epithelioid features that involve the soft tissues.

Transmembrane adhesion molecules, epithelial-type cadherin (ECAD) and neural-type cadherin (NCAD), help in regulating transformations between epithelial and mesenchymal cells in the developing embryo and in maintaining the epithelioid phenotype. Consequently, the presence of epithelioid cells in certain malignant noncarcinomatous neoplasms raises speculation that the expression of ECAD and NCAD in these neoplasms may have diagnostic significance. To investigate the utility of ECAD and NCAD immunoexpression in distinguishing malignant (noncarcinomatous) neoplasms with epithelioid features that involve the soft tissues. Membranous immunoreactivity of anti-ECAD and anti-NCAD was evaluated on archived cases selected from the files of the Armed Forces Institute of Pathology. Epithelial-type cadherin was found in biphasic synovial sarcoma (35 of 35 cases), malignant melanoma (13/21), monophasic fibrous synovial sarcoma (13/26), clear cell sarcoma (4/9), poorly differentiated synovial sarcoma (3/13), diffuse mesothelioma (4/20), malignant epithelioid peripheral nerve sheath tumor (1/6), and epithelioid sarcoma (5/62). Neural-type cadherin was observed in chordoma (11/11), biphasic synovial sarcoma (30/35), diffuse mesothelioma (14/20), malignant melanoma (14/25), epithelioid sarcoma (24/63), epithelioid angiosarcoma (1/4), poorly differentiated synovial sarcoma (2/13), clear cell sarcoma (1/10), and monophasic fibrous synovial sarcoma (1/26). Eighteen cases of primary cutaneous squamous cell carcinomas all tested positive for ECAD, whereas NCAD was focally observed in 5 cases. No expression of either molecule was observed in cases of epithelioid hemangioendothelioma (n = 9), alveolar soft part sarcoma (n = 8), and extraskeletal myxoid chondrosarcoma (n = 7). Epithelial-type and neural-type cadherins are found in a variety of noncarcinomatous neoplasms with epithelioid features that involve the soft tissues and can be utilized, in association with other immunomarkers, in distinguishing chordoma (100% NCAD) from extraskeletal myxoid chondrosarcoma and conventional chondrosarcoma of bone (0% NCAD), squamous cell carcinoma (100% ECAD) from epithelioid sarcoma (8% ECAD), and biphasic synovial sarcoma (100% ECAD) from diffuse mesothelioma (20% ECAD).

Sarcomas are a heterogeneous group of tumors with specific molecular characteristics and currently classified on the basis of their tissue of origin and histologic appearance. Except for epithelioid sarcoma, clear cell sarcoma, angiosarcoma and rhabdomyosarcoma, which may spread to regional lymph nodes, the other histotypes spread via the vascular system to the lungs most of the time. A variety of molecular approaches, including gene expression profiling, have identified candidate biomarkers and generated insights into sarcoma biology. The comprehension of the pathogenesis of this malignancy according to the mesenchymal stem cell hypothesis parallels the description of several molecular pathways deregulated in sarcoma. Individuation of vascular spread biomarkers is actually focused on the study of factors involved both in hemostasis and angiogenesis. Interestingly the microenvironment of sarcomas showed the very same mesenchymal origin of the surrounding stromal cells. The presence of circulating tumor cells and miRNAs in blood samples of sarcoma patients represents the possibility not only to better stratify patients group according to the prognosis but also to tailor new individualized therapy. So, it could be predicted that some genes expressed in a specific sarcoma might have prognostic significance or therapeutic targeting potential and molecular targets can be identified in the tumor or in the tumor microenvironment. Therefore the initial evaluation of a sarcoma patient should include in-depth genetic evaluation including karyotyping and c-DNA/protein expression profiling. The chemokine signaling demonstrated to be deeply implicated in sarcoma development as well as to have a significant role in development of metastatic disease, especially in directing tumor cells towards the preferential sites of metastases in sarcoma, lung and bone. It is unsolved if the blood stream is a more favorable environment compared to lymphatic or if lymph nodes are more efficient in destroying metastatic sarcoma cells. But the comprehension of the regulatory mechanisms of the behavior of mesenchymal malignant tumors is at its dawn.

Approximately 30% of patients with soft-tissue sarcoma die from pulmonary metastases. The mechanisms that drive sarcoma metastasis are not well understood. Recently, we identified miR-182 as a driver of sarcoma metastasis in a primary mouse model of soft-tissue sarcoma. We also observed elevated miR-182 in a subset of primary human sarcomas that metastasized to the lungs. Here, we show that myogenic differentiation factors regulate miR-182 levels to contribute to metastasis in mouse models. We find that MyoD directly binds the miR-182 promoter to increase miR-182 expression. Furthermore, mechanistic studies revealed that Pax7 can promote sarcoma metastasis in vivo through MyoD-dependent regulation of pro-metastatic miR-182. Taken together, these results suggest that sarcoma metastasis can be partially controlled through Pax7/MyoD-dependent activation of miR-182 and provide insight into the role that myogenic transcription factors have in sarcoma progression.

No simple, noninvasive method is available for evaluating extracutaneous Kaposi sarcoma in AIDS patients or for following the tumor's response to treatment. We report our preliminary experience with thallium-201 scintigraphy in nine AIDS patients with proved Kaposi sarcoma. Eight of the nine had abnormal uptake of the radionuclide in skin, lymph nodes, oral cavity, vagina, and lungs. Only four of the nine had cutaneous Kaposi sarcoma at the time of scanning. All cutaneous and mucosal lesions were thallium avid. Two of the six patients with thallium-avid nodes underwent nodal biopsy. Both biopsies confirmed the diagnosis of Kaposi sarcoma. Cutaneous Kaposimore » sarcoma developed later in one of these patients, showing the efficacy of thallium scintigraphy for the early detection of extracutaneous lesions. These preliminary results show thallium avidity in Kaposi sarcoma involving the skin and various extracutaneous sites (lymph nodes, lung, mucosa, and vagina).

Ewing's sarcoma is a highly malignant tumor of children and young adults. The molecular mechanisms that underlie Ewing's Sarcoma development are beginning to be understood. For example, most cases of this disease harbor somatic chromosomal translocations that fuse the EWSR1 gene on chromosome 22 with members of the ETS family. While some cooperative genetic events have been identified, such as mutations in TP53 or deletions of the CDKN2A locus, these appear to be absent in the vast majority of cases. It is therefore uncertain whether EWS/ETS translocations are the only consistently present alteration in this tumor, or whether there are other recurrent abnormalities yet to be discovered. One method to discover such mutations is to identify familial cases of Ewing's sarcoma and to then map the susceptibility locus using traditional genetic mapping techniques. Although cases of sibling pairs with Ewing's sarcoma exist, familial cases of Ewing's sarcoma have not been reported. While Ewing's sarcoma has been reported as a 2nd malignancy after retinoblastoma, significant associations of Ewing's sarcoma with classic tumor susceptibility syndromes have not been identified. We will review the current evidence, or lack thereof, regarding the potential of a heritable condition predisposing to Ewing's sarcoma. PMID:20300555

We sought to investigate the clinicopathological significance and biological function of hepatoma-derived growth factor (HDGF) in Ewing's sarcoma. Our results showed that HDGF expression is up-regulated in Ewing's sarcoma. Nuclear HDGF expression is significantly associated with tumour volume (p < 0.001), metastases at diagnosis (p < 0.001), low overall survival rate (p < 0.001) and low disease-free survival rate (p < 0.001). HDGF knock-down results in significant reduction of Ewing's sarcoma cell growth, proliferation and enhances tumourigenesis, both in vitro and in vivo. Meanwhile, HDGF knock-down causes cell cycle arrest and enhanced sensitization to serum starvation-induced apoptosis. Furthermore, recombinant HDGF promotes proliferation and colony formation of Ewing's sarcoma cells. Ninety-eight candidate HDGF downstream genes were identified in Ewing's sarcoma cells using cDNA microarray analysis. In addition, we found that HDGF knock-down inhibited FLI1 expression in Ewing's sarcoma cells at the mRNA and protein levels. Our findings suggest that HDGF exhibits oncogenic properties and may be a novel prognostic factor in Ewing's sarcoma. Targeting HDGF might be a potential therapeutic strategy for Ewing's sarcoma.

In order to explore the potential of immune checkpoint blockade in sarcoma, we investigated expression and clinical relevance of programmed cell death-1 (PD-1), programmed death ligand-1 (PD-L1) and CD8 in tumors of 208 sarcoma patients. Primary untreated osteosarcoma (n = 46), Ewing sarcoma (n = 32), alveolar rhabdomyosarcoma (n = 20), embryonal rhabdomyosarcoma (n = 77), synovial sarcoma (n = 22) and desmoplastic small round cell tumors (DSRCT) (n = 11) were examined immunohistochemically. PD-L1 expression was predominantly detected in alveolar and embryonal rhabdomyosarcomas (15% and 16%, respectively). In the alveolar subtype PD-L1 expression was associated with better overall, event-free and metastases-free survival. PD-1 expression on lymphocytes was predominantly seen in synovial sarcomas (18%). High levels of CD8+ lymphocytes were predominantly detected in osteosarcomas (35%) and associated with worse event-free survival in synovial sarcomas. Ewing sarcoma and DSRCTs showed PD-1 on tumor cells instead of on tumor infiltrating lymphocytes. Overall, expression and clinical associations were found to be subtype dependent. For the first time PD-1 expression on Ewing sarcoma (19%) and DSRCT (82%) tumor cells was described. PMID:29050367

Intravenous paclitaxel, 100 mg/m(2), given over 3 hours every 2 weeks is associated with a response rate of 59% in patients with recurrent or refractory acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS). However, this regimen is associated with significant myelosuppression, and the inconvenience of a 3-hour infusion. Moreover, no effective therapies have been defined for use after treatment failure with this agent. A Phase II trial was conducted with weekly docetaxel in patients with advanced-stage KS to assess safety and antitumor activity. Docetaxel was administered at a dose of 25 mg/m(2) intravenously over 15-30 minutes weekly for 8 weeks. Thereafter, if the patient experienced stable disease or better response, treatment doses were given every other week until complete disease remission, disease progression, or unacceptable toxicity occurred. Twelve patients were accrued-9 had > 25 mucocutaneous lesions, 1 had lymphedema, and 2 had visceral involvement. Ten patients (83%) had previous systemic chemotherapy, including 4 who received previous paclitaxel. Treatment was well tolerated, with no Grade 4 toxicity of any type. Grade 3 neutropenia occurred in 33% of patients but no patient had neutropenic fever. Five patients (42%) achieved a partial response, including 1 who had previously failed to respond to paclitaxel. The median time to disease progression was 26 months (range, 5-53 months). With a median follow-up period of 45 months, the median survival point had not been reached. Weekly docetaxel is safe, with reasonable antitumor activity in patients with advanced-stage, recurrent, or refractory AIDS-related KS. (c) 2004 American Cancer Society.

Despite extensive immunohistochemical (IHC) and molecular studies combined with morphologic findings, a group of round/ovoid cell tumors histologically similar to Ewing sarcomas (ES) but lacking EWSR1-rearrangements may remain unclassifiable. We retrospectively analyzed 41 Ewing-like tumors (formalin-fixed, paraffin-embedded) previously determined as negative or non-informative for EWSR1-rearrangements by FISH and/or RT-PCR. A new histopathology revision and additional IHC and molecular analyses were carried out in order to investigate whether additional IHC and/or molecular testing in combination with the morphological findings may help in reaching a definitive diagnosis. Almost all the tumors (n=40) involved soft tissue and/or bone and half the patients died of disease. In the archival cases all diagnoses were Ewing sarcoma (ES), Ewing-like sarcoma (ELS), myoepithelial tumor and undifferentiated sarcoma (US). In the new review all the tumors were re-classified as, ES (n=16), Ewing-like tumor with EWSR1 rearrangement and amplification and possible EWSR1-NFATC2 gene fusion (n=1), CIC-rearranged sarcomas or undifferentiated sarcoma, most consistent with CIC-rearranged sarcoma (n=7), sarcoma with BCOR-alteration or undifferentiated sarcoma, consistent with BCOR-associated sarcoma (n=3), neuroblastoma (n=2), unclassifiable neoplasm with neuroblastic differentiation (n=1), malignant rhabdoid tumor (n=2), lymphoblastic lymphoma (n=1), clear cell sarcoma of the gastrointestinal tract (n=1), small cell carcinoma (n=1), sclerosing rhabdomyosarcoma (n=1), desmoplastic small round cell tumor (n=1), malignant peripheral sheath nerve tumor (n=1), poorly-differentiated synovial sarcoma (n=1), Possible gastrointestinal stromal tumor/GIST with predominant round cells (n=1) and possible SMARCA4-deficient-sarcoma (n=1). NKX2.2, ETV4 and BCOR immunoreactivity was observed in all ES, CIC-rearranged sarcomas and sarcomas with BCOR alteration, respectively. CIC-rearrangement by FISH was observed in many of the CIC-rearranged sarcomas. Our analysis of 41 Ewing-like tumors confirms that there may be a significant pathological and IHC overlap among Ewing-like tumors, with prognostic and therapeutic impacts. Additional IHC (NKX2.2, ETV4 and BCOR) and molecular studies including FUS, CIC or BCOR analysis may support the final diagnosis when FISH or RT-PCR fail to detect EWSR1-rearrangements. Any molecular findings should always be interpreted in relation to the specific clinical and pathological context. Copyright © 2017 Elsevier Inc. All rights reserved.

Congenital extraskeletal Ewing's sarcoma or peripheral primitive neuroectodermal tumor is an extremely uncommon and invariably fatal tumor. We report a case of extraskeletal congenital Ewing's sarcoma in a female fetus delivered at 34 weeks of gestation who died immediately after birth. In English literature, majority of cases of Ewing's sarcoma in neonates reported were skeletal. To the best of our knowledge, very few cases of extra-skeletal Ewing's sarcoma in neonates are reported in the literature.

The University of Michigan Sarcoma Survivorship Clinic: Preventing, Diagnosing, and Treating Chronic Illness for Improved Survival and Long-Term Health.

The Children's Cancer Survivorship Study reports more chronic illnesses in sarcoma survivors than other pediatric cancers. Chemotherapy and radiation put survivors at risk for developing chronic illnesses, including heart disease, diabetes, hypertension, and kidney failure. Sarcoma survivors may have a reduced life expectancy and signs of heart disease in their 30s and 40s. Since these medical problems occur much later in the general population, they often go undetected or misdiagnosed in sarcoma survivors, creating delays in intervention and treatment. The good news is that these chronic illnesses can often be prevented or minimized. The most common adverse effect of chemotherapy and radiation is coronary artery disease (CAD). CAD has a number of risk factors, including hypertension, diabetes, obesity, and dyslipidemia. These risk factors are modifiable with lifestyle changes, including diet and exercise, and/or pharmacological intervention. By identifying and managing risk factors like hypertension early, we in turn reduce the risk for CAD and prolong survival. This is well established in the general population; there is no reason a priori not to apply it to sarcoma survivors. Sarcoma survivors should be followed by physicians who understand the late effects and outcomes of sarcoma treatment. The University of Michigan Sarcoma Survivorship Clinic provides long-term care for sarcoma survivors by preventing, diagnosing, and treating the adverse long-term physical and psychological effects associated with sarcoma survivorship.

More than half of all sarcomas occur in adolescents and young adults (AYAs) aged 15 to 39 years. After the publication of the AYA series in the April 1, 2016 issue of Cancer, several leaders in the field of sarcoma across disciplines gathered to discuss the status of sarcoma clinical research in AYAs. They determined that a focused effort to include the underrepresented and understudied AYA population in current and future sarcoma clinical trials is overdue. Trial enrichment for AYA-aged sarcoma patients will produce more meaningful results that better represent the disease's biology, epidemiology, and treatment environment. To address the current deficit, this commentary outlines changes believed to be necessary to expediently achieve an increase in the enrollment of AYAs in sarcoma clinical trials.

Sarcomas are infrequent mesenchymal neoplasms characterized by notable morphological and molecular heterogeneity. Molecular studies in sarcoma provide refinements to morphologic classification, and contribute diagnostic information (frequently), prognostic stratification (rarely) and predict therapeutic response (occasionally). Herein, we summarize the major molecular mechanisms underlying sarcoma pathogenesis and present clinically useful diagnostic, prognostic and predictive molecular markers for sarcoma. Five major molecular alterations are discussed, illustrated with representative sarcoma types, including 1. the presence of chimeric transcription factors, in vascular tumors; 2. abnormal kinase signaling, in gastrointestinal stromal tumor; 3. epigenetic deregulation, in chondrosarcoma, chondroblastoma, and other tumors; 4. deregulated cell survival and proliferation, due to focal copy number alterations, in dedifferentiated liposarcoma; 5. extreme genomic instability, in conventional osteosarcoma as a representative example of sarcomas with highly complex karyotype.

Primary Undifferentiated Pleomorphic Sarcoma of the Penis

PubMed Central

Yoo, Hyung Sun; Satti, Suma

2017-01-01

Background: Primary penile sarcoma is a rare disease that affects men of all ages. Different subtypes of primary penile sarcoma exist, with the rarest being pleomorphic sarcoma. Delays in presentation and diagnosis of primary penile sarcoma have been reported because of its benign-appearing presenting features and rarity. If penile sarcoma is left untreated, the clinical consequence is metastasis that is fatal in most cases. Case Report: We report an extremely rare case of undifferentiated pleomorphic sarcoma of the penis in a 59-year-old patient who initially presented with a slow-growing penile nodule. The tumor was surgically excised, but the patient experienced local recurrence and, despite receiving chemotherapy and surgery, died of metastatic disease 15 months after initial presentation. Conclusion: Vigilance regarding biopsy and intervention for penile nodules may lead to early diagnosis and improved clinical outcomes. PMID:29230132

Patients with metastatic or recurrent and refractory sarcomas have a dismal prognosis. Therefore, new targeted therapies are urgently needed. This study was designed to evaluate chimeric antigen receptor (CAR) T cells targeting the type I insulin-like growth factor receptor (IGF1R) or tyrosine kinase-like orphan receptor 1 (ROR1) molecules for their therapeutic potential against sarcomas. Here, we report that IGF1R (15/15) and ROR1 (11/15) were highly expressed in sarcoma cell lines including Ewing sarcoma, osteosarcoma, alveolar or embryonal rhabdomyosarcoma, and fibrosarcoma. IGF1R and ROR1 CAR T cells derived from eight healthy donors using the Sleeping Beauty (SB) transposon system were cytotoxic against sarcoma cells and produced high levels of IFN-γ, TNF-α and IL-13 in an antigen-specific manner. IGF1R and ROR1 CAR T cells generated from three sarcoma patients released significant amounts of IFN-γ in response to sarcoma stimulation. The adoptive transfer of IGF1R and ROR1 CAR T cells derived from a sarcoma patient significantly reduced tumor growth in pre-established, systemically disseminated and localized osteosarcoma xenograft models in NSG mice. Infusion of IGF1R and ROR1 CAR T cells also prolonged animal survival in a localized sarcoma model using NOD/scid mice. Our data indicate that both IGF1R and ROR1 can be effectively targeted by SB modified CAR T cells and that such CAR T cells may be useful in the treatment of high risk sarcoma patients.

Epidemiological and genetic clues for molecular mechanisms involved in uterine leiomyoma development and growth.

2015-01-01

Uterine leiomyomas (fibroids) are highly prevalent benign smooth muscle tumors of the uterus. In the USA, the lifetime risk for women developing uterine leiomyomas is estimated as up to 75%. Except for hysterectomy, most therapies or treatments often provide only partial or temporary relief and are not successful in every patient. There is a clear racial disparity in the disease; African-American women are estimated to be three times more likely to develop uterine leiomyomas and generally develop more severe symptoms. There is also familial clustering between first-degree relatives and twins, and multiple inherited syndromes in which fibroid development occurs. Leiomyomas have been described as clonal and hormonally regulated, but despite the healthcare burden imposed by the disease, the etiology of uterine leiomyomas remains largely unknown. The mechanisms involved in their growth are also essentially unknown, which has contributed to the slow progress in development of effective treatment options. A comprehensive PubMed search for and critical assessment of articles related to the epidemiological, biological and genetic clues for uterine leiomyoma development was performed. The individual functions of some of the best candidate genes are explained to provide more insight into their biological function and to interconnect and organize genes and pathways in one overarching figure that represents the current state of knowledge about uterine leiomyoma development and growth. In this review, the widely recognized roles of estrogen and progesterone in uterine leiomyoma pathobiology on the basis of clinical and experimental data are presented. This is followed by fundamental aspects and concepts including the possible cellular origin of uterine fibroids. The central themes in the subsequent parts are cytogenetic aberrations in leiomyomas and the racial/ethnic disparities in uterine fibroid biology. Then, the attributes of various in vitro and in vivo, human syndrome, rodent xenograft, naturally mutant, and genetically modified models used to study possible molecular mechanisms of leiomyoma development and growth are described. Particular emphasis is placed on known links to fibrosis, hypertrophy, and hyperplasia and genes that are potentially important in these processes. Menstrual cycle-related injury and repair and coinciding hormonal cycling appears to affect myometrial stem cells that, at a certain stage of fibroid development, often obtain cytogenetic aberrations and mutations of Mediator complex subunit 12 (MED12). Mammalian target of rapamycin (mTOR), a master regulator of proliferation, is activated in many of these tumors, possibly by mechanisms that are similar to some human fibrosis syndromes and/or by mutation of upstream tumor suppressor genes. Animal models of the disease support some of these dysregulated pathways in fibroid etiology or pathogenesis, but none are definitive. All of this suggests that there are likely several key mechanisms involved in the disease that, in addition to increasing the complexity of uterine fibroid pathobiology, offer possible approaches for patient-specific therapies. A final model that incorporates many of these reported mechanisms is presented with a discussion of their implications for leiomyoma clinical practice. © The Author 2015.

Oestrogen dramatically increases uterine blood flow (UBF) in ovariectomized (Ovx) ewes. Both the follicular phase and pregnancy are normal physiological states with elevated levels of circulating oestrogen. ICI 182 780 is a pure steroidal oestrogen receptor (ER) antagonist that blocks oestrogenic actions in oestrogen-responsive tissue. We hypothesized that an ER-mediated mechanism is responsible for in vivo rises in UBF in physiological states of high oestrogen. The purpose of the study was to examine the effect of an ER antagonist on exogenous and endogenous oestradiol-17beta (E2beta)-mediated elevations in UBF. Sheep were surgically instrumented with bilateral uterine artery blood flow transducers, and uterine and femoral artery catheters. Ovx animals (n = 8) were infused with vehicle (35% ethanol) or ICI 182 780 (0.1-3.0 microg min(-1)) into one uterine artery for 10 min before and 50 min after E2beta was given (1 microg kg(-1) I.V. bolus) and UBF was recorded for an additional hour. Intact, cycling sheep were synchronized to the follicular phase using progesterone, prostaglandin F2alpha(PGF2alpha) and pregnant mare serum gonadotrophin (PMSG). When peri-ovulatory rises in UBF reached near peak levels, ICI 182 780 (1 or 2 microg (ml uterine blood flow)-1) was infused unilaterally (n = 4 sheep). Ewes in the last stages of pregnancy (late pregnant ewes) were also given ICI 182 780 (0.23-2.0 microg (ml uterine blood flow)-1; 60 min infusion) into one uterine artery (n = 8 sheep). In Ovx sheep, local infusion of ICI 182 780 did not alter systemic cardiovascular parameters, such as mean arterial blood pressure or heart rate; however, it maximally decreased ipsilateral, but not contralateral, UBF vasodilatory responses to exogenous E2beta by approximately 55-60% (P < 0.01). In two models of elevated endogenous E2beta, local ICI 182 780 infusion inhibited the elevated UBF seen in follicular phase and late pregnant ewes in a time-dependent manner by approximately 60% and 37%, respectively; ipsilateral > contralateral effects (P < 0.01). In late pregnant sheep ICI 182 780 also mildly and acutely (for 5-30 min) elevated mean arterial pressure and heart rate (P < 0.05). We conclude that exogenous E2beta-induced increases in UBF in the Ovx animal and endogenous E2beta-mediated elevations of UBF during the follicular phase and late pregnancy are partially mediated by ER-dependent mechanisms.

In two models of elevated endogenous E2β, local ICI 182 780 infusion inhibited the elevated UBF seen in follicular phase and late pregnant ewes in a time-dependent manner by ∼60% and 37%, respectively; ipsilateral ≫ contralateral effects (P < 0.01). In late pregnant sheep ICI 182 780 also mildly and acutely (for 5–30 min) elevated mean arterial pressure and heart rate (P < 0.05).

Ewing’s sarcoma is the second most common pediatric bone tumor. Primary Ewing’s sarcoma occurring in the cerebral cranium is exceptionally rare, with only one reported case of multiple tumor lesions in adolescence to date. We report a case of a 5-year-old male patient with multiple primary Ewing’s sarcomas associated with the cranial bones, the first pediatric case report to date. We also review 71 cases Ewing’s sarcoma involving intracranial extension. The purpose of this article is to provide data concerning the clinical and therapeutic course of multiple primary Ewing’s sarcomas in associated with cerebral cranium. PMID:26261672

Epithelioid sarcoma, first described by Enzinger in 1970, is a rare soft-tissue sarcoma typically presenting as a subcutaneous or deep dermal mass in distal portions of the extremities of adolescents and young adults. In 1997, Guillou et al. described a different type of epithelioid sarcoma, called proximal-type epithelioid sarcoma, which is found mostly in the pelvic and perineal regions and genital tracts of young to middle-aged adults. It is characterized by a proliferation of epithelioid-like cells with rhabdoid features and the absence of a granuloma-like pattern. In this paper we present a case of proximal-type epithelioid sarcoma with an aggressive clinical course, including distant metastasis and death nine months after diagnosis. PMID:23793215

Synovial sarcoma is a rare soft tissue sarcoma of the head and neck region involving the parapharyngeal space. The diagnosis of synovial sarcoma can be very challenging to the pathologists. We present a rare case of parapharyngeal synovial sarcoma in a young female patient who had a two-month history of left cervical intumescent mass at level II. The fine needle aspiration cytology of the mass was proved inconclusive. Transcervical excision of the mass was performed and the first case of parapharyngeal sarcoma was identified in our center by fluorescence in situ hybridization (FISH) technique. Repeat imaging revealed residual tumor. The patient successfully underwent a second excision of the residual tumor and received adjuvant radiotherapy.

Modern multimodal treatment has significantly increased survival for patients affected by hematologic malignancies, especially in childhood. Following remission, however, the risk of developing a further malignancy is an important issue. The long-term estimated risk of developing a sarcoma as a secondary malignancy is increased severalfold in comparison to the general population. Ewing's sarcoma family encompasses a group of highly aggressive, undifferentiated, intra- and extraosseous, mesenchymal tumors, caused by several types of translocations usually involving the EWSR1 gene. Translocation associated sarcomas, such as Ewing sarcoma, are only rarely encountered as therapy associated secondary tumors. We describe the clinical course and management of three patients from a single institution with Ewing's sarcoma that followed successfully treated lymphoblastic T-cell leukemia or non-Hodgkin lymphoma. The literature on secondary Ewing's sarcoma is summarized and possible pathogenic mechanisms are critically discussed.

Synovial sarcoma is a malignant tumor of soft tissue that is rarely found in the head and neck. Even less common are metastasis within the head and neck. We describe a case of a delayed metastatic synovial sarcoma to the scalp. A man who had been diagnosed and treated 16 years previously for monophasic synovial sarcoma of the groin, presented with a new scalp lesion confirmed to be metastatic monophasic synovial sarcoma. Wide local excision and sentinel lymph node biopsy (SLNB) were performed and adjuvant radiation therapy was deferred. A positron emission tomography (PET)/CT was obtained 3 months after surgery and showed no evidence of local recurrence or metastatic disease. This case report describes a rare case of synovial sarcoma metastasizing to the scalp. The genetic, histopathologic, and clinical features of synovial sarcoma are reviewed with a focus on their manifestation and management within the head and neck. © 2015 Wiley Periodicals, Inc.

Kaposi's sarcoma is the most common form of cancer in patients with human immunodeficiency virus (HIV) infection. Although Kaposi sarcoma lesions may contribute to significant physical impairments, there is a lack of scientific literature detailing the role of physiotherapy in the treatment of HIV-associated Kaposi's sarcoma. The present Case Report includes two males, aged 36 and 39 years, seropositive for HIV with invasive Kaposi's sarcoma. Patient A was evaluated for bilateral foot pain caused by plantar surface Kaposi s sarcoma lesions that rendered him unable to walk. He progressed to walking 400feet after a treatment regimen of gait training with the use of custom plastazote sandals. Patient B was evaluated for right lower extremity lymphoedema secondary to invasive Kaposi's sarcoma. He experienced an 18% reduction in limb volume, a 38% reduction in pain and a 20 degrees increase in terminal knee flexion after therapeutic exercise and the use of compressive bandaging and garments. This Case Report suggests that physiotherapy interventions may be valuable in the conservative management of patients with HIV-associated Kaposi s sarcoma.

Ewing's sarcomas are aggressive musculoskeletal tumors occurring most frequently in the long and flat bones as a solitary lesion mostly during the teen-age years of life. With current treatments, significant number of patients relapse and survival is poor for those with metastatic disease. As part of novel target discovery in Ewing's sarcoma, we applied RNAi mediated phenotypic profiling to identify kinase targets involved in growth and survival of Ewing's sarcoma cells. Four Ewing's sarcoma cell lines TC-32, TC-71, SK-ES-1 and RD-ES were tested in high throughput-RNAi screens using a siRNA library targeting 572 kinases. Knockdown of 25 siRNAs reduced the growth of all four Ewing's sarcoma cell lines in replicate screens. Of these, 16 siRNA were specific and reduced proliferation of Ewing's sarcoma cells as compared to normal fibroblasts. Secondary validation and preliminary mechanistic studies highlighted the kinases STK10 and TNK2 as having important roles in growth and survival of Ewing's sarcoma cells. Furthermore, knockdown of STK10 and TNK2 by siRNA showed increased apoptosis. In summary, RNAi-based phenotypic profiling proved to be a powerful gene target discovery strategy, leading to successful identification and validation of STK10 and TNK2 as two novel potential therapeutic targets for Ewing's sarcoma.

In large autopsy series, the estimated frequency of primary tumors of the heart ranges from 0.0017% to 0.33%. Approximately 25% of primary cardiac tumors are malignant, and nearly 20% of these are sarcomas. To date, a completely feasible surgical resection remains the major treatment measure of cardiac sarcoma, especially for recurrent focal cardiac sarcoma and the recurrence of a restrictive metastasis. Although characteristically medical treatments are recommended, there is no consistent opinion for adjuvant radiotherapy and chemotherapy following an operation. Since these tumors usually undergo extensive spread by the time that the diagnosis is established, the prognosis of cardiac sarcoma remains poor. In this report, we described a case who underwent initial cardiac tumor resection, and was confirmed to be a pleomorphic undifferentiated sarcoma based on pathological findings. However, the patient complicated with cerebral infarction and subsequent brain metastasis sarcoma after the initial surgery, which was confirmed by brain tissue pathology. During the course of therapy, the patient underwent three surgical operations and refused to accept any chemotherapy and radiotherapy intervention. To the best of our knowledge, this is the first case report describing a primary cardiac sarcoma complicated with cerebral infarction and brain metastasis. The management of primary cardiac sarcoma is also discussed.

Sarcomas are a rare subgroup of pediatric cancers comprised of a variety of bone and soft-tissue tumors. While significant advances have been made in improving outcomes of patients with localized pediatric sarcomas since the addition of systemic chemotherapy to local control many decades ago, outcomes for patients with metastatic and relapsed sarcoma remain poor with few novel therapeutics identified to date. With the advent of new technologies to study cancer genomes, transcriptomes and epigenomes, our understanding of sarcoma biology has improved tremendously in a relatively short period of time. However, much remains to be accomplished in this arena especially with regard to translating all of this new knowledge to the bedside. To this end, a meeting was convened in Philadelphia, PA, on April 18, 2015 sponsored by the QuadW foundation, Children's Oncology Group and CureSearch for Children's Cancer that brought together sarcoma clinicians and scientists from North America to review the current state of pediatric sarcoma biology and ongoing/planned genomics based clinical trials in an effort to identify and bridge knowledge gaps that continue to exist at present. At the conclusion of the workshop, three key objectives that would significantly further our understanding of sarcoma were identified and a proposal was put forward to develop an all-encompassing pediatric sarcoma biology protocol that would address these specific needs. This review summarizes the proceedings of the workshop. Copyright © 2016. Published by Elsevier Inc.

Objective To evaluate the safety and survival in women treated with adjuvant pelvic radiation “sandwiched” between six cycles of paclitaxel and carboplatin chemotherapy with completely resected UPSC. Methods Surgically staged women with UPSC (FIGO stage 1-4) and no visible residual disease were enrolled. Treatment involved paclitaxel (175 mg/m2) and carboplatin (AUC=6.0-7.5) every 21 days for 3 doses, followed by radiation therapy (RT), followed by an additional 3 cycles of paclitaxel and carboplatin (AUC=5-6). Survival analysis, using Kaplan-Meier methods, was performed on patients who completed at least 3 cycles of chemotherapy and RT. Results A total of 81 patients were enrolled, of which 72 patients completed the first 3 cycles of chemotherapy followed by prescribed RT. Median age was 67 years (range: 43–82 years). 59/72 (82%) had disease confined to the uterus and 13/72 (18%) had completely resected extra-uterine disease (stage 3&4). 65 (83%) completed the protocol. Overall PFS and OS for combined stage 1&2 patients was 65.5±3.6 months and 76.5±4.3 months, respectively. PFS and OS for combined stage 3&4 patients was 25.8±3.0 and 35.9±5.3 months, respectively. Three-year % survival probability for stage 1&2 patients was 84% and for stage 3&4 patients was 50%. Of the 435 chemotherapy cycles administered, there were 11(2.5%) G3/G4 non-hematologic toxicities. 26(6.0%) cycles had dose reductions and 37(8.5%) had dose delays. Conclusions Compared to prior studies of single modality adjuvant therapy, RT “sandwiched” between paclitaxel and carboplatin chemotherapy is well-tolerated and highly efficacious in women with completely resected UPSC.

The aim of this study was to summarize the clinical and pathological characteristics and to conduct prognosis analysis of patients who were diagnosed with clear cell carcinoma of the uterine cervix (CCCUC) and without a history of exposure to diethylstilbestrol. We performed a retrospective review of all the patients with CCCUC who were diagnosed and treated at Zhejiang Cancer Hospital between 1998 and 2014. Charts were reviewed for clinical and pathological characteristics, and prognosis analysis was conducted. A total of 47 patients were included. Median age was 52 years. No patient had a history of exposure to diethylstilbestrol. The International Federation of Gynecology and Obstetrics stage distribution was 55.3% (n = 26) stage I, 40.4% (n = 19) stage II, 2.1% (n = 1) stage III, and 2.1% (n = 1) stage IV. Forty-two patients (89.4%) underwent radical hysterectomy and pelvic lymphadenectomy. Pathological examination revealed deep cervical stromal invasion (greater than two thirds) in 20 patients (48.4%), pelvic lymph node (PLN) metastasis in 10 patients (23.8%), lymphovascular space involvement in 9 patients (21.4%), and ovarian metastasis in 1 patient (2.4%). Advanced tumor stage (IIB-IV), larger tumor size (>4 cm), and PLN metastasis had negative effects on progression-free survival (PFS) and overall survival (OS) (P < 0.05). Adjuvant radiation therapy alone or concurrent chemoradiation therapy after radical surgery did not affect PFS or OS in patients with risk factors (P > 0.05). International Federation of Gynecology and Obstetrics stage, tumor size, and PLN status were prognostic factors for both PFS and OS in patients with CCCUC. The long-term effects of adjuvant radiation therapy or concurrent chemoradiation therapy may be limited for CCCUC patients with risk factors. Future larger case series or clinical trials are required to confirm these findings.

In uterine cervical canal carcinoma, the current clinical FIGO criteria often fail not only to differentiate stage IA2 from stage IB but also to demonstrate possible parametrial involvement. Moreover, the analysis of tumor volume and of the depth of neoplastic stromal invasion is not very reliable. The authors investigated MR accuracy in the definition of such variables: to this purpose, 24 patients with histologically confirmed endocervical adenocarcinoma were submitted to MRI, which was performed with an 0.5-T superconductive magnet. Sagittal and oblique transverse or sometimes coronal SE images, oriented so as to be perpendicular to longitudinal cervical major axis were obtained with T2 weighting (TR 1800 ms, TE 25-90 ms). MR data were correlated with pathologic findings. MR accuracy in demonstrating parametrial involvement was 92%, its sensitivity was 86% and specificity 97%. Volumetric MR data showed a high correlation (r = 0.970) with those derived from pathologic findings. In 92% of cases stromal invasion exceeded 5 mm. MRI, thanks to its high accuracy, should be included in diagnostic pretreatment protocols, even though FIGO criteria do not require it yet, especially in the presence of an endocervical adenocarcinoma. Moreover, the accurate definition of tumor volume can allow less extensive surgery with the same survival rates and fewer complications, which are frequently observed after radical hysterectomy.

Due to the ongoing evolution of nanotechnology, there is a growing need to assess the toxicological outcomes in under-studied populations in order to properly consider the potential of engineered nanomaterials (ENM) and fully enhance their safety. Recently, we and others have explored the vascular consequences associated with gestational nanomaterial exposure, reporting microvascular dysfunction within the uterine circulation of pregnant dams and the tail artery of fetal pups. It has been proposed (via work derived by the Barker Hypothesis) that mitochondrial dysfunction and subsequent oxidative stress mechanisms as a possible link between a hostile gestational environment and adult disease. Therefore, in this study, we exposed pregnant Sprague-Dawley rats to nanosized titanium dioxide aerosols after implantation (gestational day 6). Pups were delivered, and the progeny grew into adulthood. Microvascular reactivity, mitochondrial respiration and hydrogen peroxide production of the coronary and uterine circulations of the female offspring were evaluated. While there were no significant differences within the maternal or litter characteristics, endothelium-dependent dilation and active mechanotransduction in both coronary and uterine arterioles were significantly impaired. In addition, there was a significant reduction in maximal mitochondrial respiration (state 3) in the left ventricle and uterus. These studies demonstrate microvascular dysfunction and coincide with mitochondrial inefficiencies in both the cardiac and uterine tissues, which may represent initial evidence that prenatal ENM exposure produces microvascular impairments that persist throughout multiple developmental stages.

Variable Expression of PIK3R3 and PTEN in Ewing Sarcoma Impacts Oncogenic Phenotypes

Ewing Sarcoma is an aggressive malignancy of bone and soft tissue affecting children and young adults. Ewing Sarcoma is driven by EWS/Ets fusion oncoproteins, which cause widespread alterations in gene expression in the cell. Dysregulation of receptor tyrosine kinase signaling, particularly involving IGF-1R, also plays an important role in Ewing Sarcoma pathogenesis. However, the basis of this dysregulation, including the relative contribution of EWS/Ets-dependent and independent mechanisms, is not well understood. In the present study, we identify variable expression of two modifiers of PI3K signaling activity, PIK3R3 and PTEN, in Ewing Sarcoma, and examine the consequences of this on PI3K pathway regulation and oncogenic phenotypes. Our findings indicate that PIK3R3 plays a growth-promotional role in Ewing Sarcoma, but suggest that this role is not strictly dependent on regulation of PI3K pathway activity. We further show that expression of PTEN, a well-established, potent tumor suppressor, is lost in a subset of Ewing Sarcomas, and that this loss strongly correlates with high baseline PI3K pathway activity in cell lines. In support of functional importance of PTEN loss in Ewing Sarcoma, we show that re-introduction of PTEN into two different PTEN-negative Ewing Sarcoma cell lines results in downregulation of PI3K pathway activity, and sensitization to the IGF-1R small molecule inhibitor OSI-906. Our findings also suggest that PTEN levels may contribute to sensitivity of Ewing Sarcoma cells to the microtubule inhibitor vincristine, a relevant chemotherapeutic agent in this cancer. Our studies thus identify PIK3R3 and PTEN as modifiers of oncogenic phenotypes in Ewing Sarcoma, with potential clinical implications. PMID:25603314

BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

Sarcomas are a heterogeneous group of rare malignancies arising from mesenchymal tissue. Although several occupational exposures have been evaluated in association with sarcoma, little is known about the role of socioeconomic indicators such as education. Socioeconomic status has been found to be associated with risk of development of several types of cancers, primarily lung, gastric, and cervical cancers. We conducted a hospital-based case-control study to evaluate the association of socioeconomic level with the risk for sarcoma. A total of 371 incident cases of sarcoma were matched in terms of age, sex, and year of enrollment in the study with 742 cancer-free controls. Education and income levels were evaluated as the indicators of socioeconomic status. Higher education (college level) was associated with a significantly lower risk for sarcoma [odds ratio (OR)=0.48, 95% confidence interval (CI)=0.29-0.80], even after adjusting for important confounders. After stratifying by sex, significantly lower risk for sarcoma was observed among men who had college level education compared with men with a level of education of eighth grade or lower (OR=0.38, 95% CI=0.19-0.74). A significant association between education and the risk for sarcoma remained after stratifying by income (OR=0.49, 95% CI=0.28-0.86, among the low income group). When analyzed as a composite exposure, individuals with high education and high income status had significantly lower risk for sarcoma compared with those with low income and low education status (OR=0.41, 95% CI=0.23-0.71). Thus, socioeconomic factors may play a significant role in determining the risk for sarcoma and should be explored further to elucidate the underlying factors that may explain these sociodemographic inequalities related to sarcoma.

To determine outcome associated with cutaneous tumors treated via intratumoral chemotherapy with cisplatin and identify risk factors affecting local tumor control and complications in equidae. Retrospective case series. 573 equidae with 630 cutaneous tumors. Medical records of horses, mules, donkeys, and ponies with cutaneous tumors treated via intratumoral chemotherapy with cisplatin were analyzed. 549 horses, 13 mules, 8 donkeys, and 3 ponies with 630 histologically confirmed cutaneous tumors were included. Tumors included sarcoids (n = 409), squamous cell carcinomas (151), soft tissue sarcomas (28), cutaneous lymphomas (26), and melanomas (16). Overall cure rate, defined as local control at 4 years, was 93.3%. For all tumor stages combined, cure rates after 1 course of treatment were 96.3% for sarcoids, 96% for lymphomas, 88% for squamous cell carcinomas, 85% for soft tissue sarcomas, and 81% for melanomas. Treatment protocol, tumor stage, and prior treatment were significant prognostic factors for tumor control. Treatment efficacy was lower for large tumors, those with gross postoperative residual disease, and those that had been treated previously with other modalities. Treatment was well tolerated. Local reactions were more likely to occur and to be more severe after the third and fourth treatment sessions. Results confirmed the value of intratumoral chemotherapy with cisplatin for treatment of cutaneous tumors in equidae. The results cannot be extrapolated to other formulations of cisplatin or other protocols that might be used.

Purpose The aim of this retrospective study was to determine, at baseline, the prognostic value of different FDG-PET/CT quantitative parameters in a homogenous Ewing Sarcoma Family of Tumors (ESFT) adult population, compared with clinically relevant prognostic factors. Methods Adult patients from 3 oncological centers, all with proved ESFT, were retrospectively included. Quantitative FDG-PET/CT parameters (SUV (maximum, peak and mean), metabolic tumor volume (MTV) and total lesion glycolysis (TLG) of the primary lesion of each patient were recorded before treatment, as well as usual clinical prognostic factors (stage of disease, location, tumor size, gender and age). Then, their relation with progression free survival (PFS) and overall survival (OS) was evaluated. Results 32 patients were included. Median age was 21 years (range, 15 to 61). Nineteen patients (59%) were initially metastatic. On multivariate analysis, high SUVmax remained independent predictor of worst OS (p=0.02) and PFS (p=0.019), metastatic disease of worst PFS (p=0.01) and high SUVpeak of worst OS (p=0.01). Optimal prognostic cut-off of SUVpeak was found at 12.5 in multivariate analyses for PFS and OS (p=0.0001). Conclusions FDG-PET/CT, recommended at ESFT diagnosis for initial staging, can be a useful tool for predicting long-term adult patients outcome through semi-quantitative parameters. PMID:29100369

Ewing's sarcoma usually arises in the bones of children and adolescents. We herein report a 74-year-old man with Ewing's sarcoma in the adrenal gland. The diagnosis was confirmed by a genetic test, pathological studies, and several imaging studies. He already had multiple liver metastases when he was transferred to our hospital and died on the 37th day. The diagnosis was further confirmed by autopsy studies. Adrenal Ewing's sarcoma is very rare, and our patient was older than other reported cases. Ewing's sarcoma should be considered even in elderly patients with adrenal tumors.

Seven cases of soft tissue sarcoma developing after primary or postoperative radiotherapy for breast carcinoma are reported. The sarcomas occurred within the irradiated volume, after a latent period of 4-26 years. These cases conform well to established criteria for the diagnosis of radiation-induced sarcoma. Chemotherapy, consisting of the four-drug combination CYVADIC (cyclophosphamide, vincristine, adriamycin, DTIC) was employed in six of the seven patients. Only two of them achieved partial remission, lasting only 2 and 3 months, respectively. The effectiveness of adriamycin-containing chemotherapy regimens in soft tissue sarcomas as well as the remote hazard of radiation-related sarcoma in primary or postoperativemore » breast irradiation are discussed.« less

To determine the reproducibility of classifying uterine fibroids using the 2011 International Federation of Gynecology and Obstetrics (FIGO) staging system. The present retrospective cohort study included patients presenting for the treatment of symptomatic uterine fibroids at the Gynecology Fibroid Clinic at Mayo Clinic, Rochester, USA, between April 1, 2013 and April 1, 2014. Magnetic resonance imaging of fibroid uteri was performed and the images were independently reviewed by two academic gynecologists and two radiologists specializing in fibroid care. Fibroid classifications assigned by each physician were compared and the significance of the variations was graded by whether they would affect surgical planning. There were 42 fibroids from 23 patients; only 6 (14%) fibroids had unanimous classification agreement. The majority (36 [86%]) had at least two unique answers and 4 (10%) fibroids had four unique classifications. Variations in classification were not associated with physician specialty. More than one-third of the classification discrepancies would have impacted surgical planning. FIGO fibroid classification was not consistent among four fibroid specialists. The variation was clinically significant for 36% of the fibroids. Additional validation of the FIGO fibroid classification system is needed. © 2017 International Federation of Gynecology and Obstetrics.

A 65-year-old woman complaining of fetor ex vagina was diagnosed with endometrial adenocarcinoma of the uterus based on the pathological findings of an endometrial biopsy. Sigmoid colon cancer was found on a pre-operative CT scan. Diagnosis of double cancer was made and we performed sigmoidectomy and panhysterectomy with associated resection of both adnexa. Histopathological examination found that the tumor accounted for almost all of the uterine mucosa and over half of the muscular layer. Immunostaining showed CK7 (-), CK20 (+), CDX2 (+), ER (-), and PgR (-), and we diagnosed it as a metastasis to the uterus of the sigmoid colon cancer. The pathological diagnosis was a moderately differentiated adenocarcinoma, pT4b (SI: urinary bladder), pN0 (0/12), H0, P1,M1a (uterus), pStage Ⅳ. As adjuvant chemotherapy, she was administered XELOX for 6 months. Although colorectal cancer rarely metastasizes to the uterus, due to the increase in the prevalence of colorectal cancer, it may be also increase. To choose the best treatment course, it is necessary to diagnose whether it is a primary uterine cancer or a metastatic uterine cancer.

There is paucity of data in regard to prognostic factors and outcome of women with 2009 FIGO stage II disease. The objective of this study was to investigate prognostic factors, recurrence patterns and survival endpoints in this group of patients. Data from four academic institutions were analyzed. 130 women were identified with 2009 FIGO stage II. All patients underwent hysterectomy, oophorectomy and lymph node evaluation with or without pelvic and paraaortic lymph node dissections and peritoneal cytology. The Kaplan-Meier approach and Cox regression analysis were used to estimate recurrence-free (RFS), disease-specific (DSS) and overall survival (OS). Median follow-up was 44months. 120 patients (92%) underwent simple hysterectomy, 78% had lymph node dissection and 95% had peritoneal cytology examination. 99 patients (76%) received adjuvant radiation treatment (RT). 5-year RFS, DSS and OS were 77%, 90%, and 72%, respectively. On multivariate analysis of RFS, adjuvant RT, the presence of lymphovascular space invasion (LVSI) and high tumor grades were significant predictors. For DSS, LVSI and high tumor grades were significant predictors while older age and high tumor grade were the only predictors of OS. In this multi-institutional study, disease-specific survival for women with FIGO stage II uterine endometrioid carcinoma is excellent. High tumor grade, lymphovascular space invasion, adjuvant radiation treatment and old age are important prognostic factors. There was no significant difference in the outcome between patients who received vaginal cuff brachytherapy compared to those who received pelvic external beam radiation treatment.

To identify the incidence of fetal heart rate (FHR) accelerations in the second stage of labor and the role of fetal electrocardiograph (ECG) in avoiding misidentification of maternal heart rate (MHR) as FHR. Retrospective observational study. University hospital labor ward, London, UK. Cardiotocograph (CTG) tracings of 100 fetuses monitored using external transducers and internal scalp electrodes. CTG traces that fulfilled inclusion criteria were selected from an electronic FHR monitoring database. Rate of accelerations during external and internal monitoring as well as decelerations for a period of 60 minutes prior to delivery were determined. The role of fetal ECG in differentiating between MHR and FHR trace was explored. Decelerations occurred in 89% of CTG traces during the second stage of labor. Accelerations indicating possible recording of FHR or MHR were found in 28.1 and 10.9% of cases recorded by an external ultrasound transducer as well as internal scalp electrode, respectively. Accelerations coinciding with uterine contractions occurred only in 11.7 and 4% of external and internal recording of FHR, respectively. Absence of 'p-wave' of the ECG waveform was associated with MHR trace. Decelerations were the commonest CTG feature during the second stage of labor. The incidence of accelerations coinciding with uterine contractions was less than half in fetuses monitored using a fetal scalp electrode. Analysing the ECG waveform for the absence of 'p-wave' helps in differentiating MHR from FHR. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

To study the prognostic impact of baby boomer (BB) generation on survival end-points of patients with early-stage endometrial carcinoma (EC). Data were obtained from the SEER registry between 1988-2009. Inclusion criteria included women who underwent hysterectomy for stage I-II EC. Patients were divided into two birth cohorts: BB (women born between 1946 and 1964) and pre-boomers (PB) (born between 1926 and 1945). A total of 30,956 patients were analyzed. Considering that women in the PB group were older than those of the BB generation, the statistical analysis was limited to women 50-59 years of age at the time of diagnosis (n=11,473). Baby boomers had a significantly higher percentage of endometrioid histology (p<0.0001), higher percentage of African American women (p<0.0001), lower tumor grade (p<0.0001), higher number of dissected lymph nodes (LN) (p<0.0001), and less utilization of adjuvant radiation therapy (p=0.0003). Overall survival was improved in women in the BB generation compared to the PB generation (p=0.0003) with a trend for improved uterine cancer-specific survival (p=0.0752). On multivariate analysis, birth cohort (BB vs. PB) was not a significant predictor of survival end-points. Factors predictive of survival included: tumor grade, FIGO stage, African-American race, and increased number of dissected LN. Our study suggests that the survival of BB women between 50-60 years of age is better compared to women in the PB generation. As more BB patients are diagnosed with EC, further research is warranted.

Purpose: To retrospectively assess prognostic factors and patterns of recurrence in patients with pathologic Stage III endometrial cancer. Methods and Materials: Between 1989 and 2003, 107 patients with pathologic International Federation of Gynecology and Obstetrics Stage III endometrial adenocarcinoma confined to the pelvis were treated at our institution. Adjuvant radiotherapy (RT) was delivered to 68 patients (64%). The influence of multiple patient- and treatment-related factors on pelvic and distant control and overall survival (OS) was evaluated. Results: Median follow-up for patients at risk was 41 months. Five-year actuarial OS was significantly improved in patients treated with adjuvant RT (68%) comparedmore » with those with resection alone (50%; p = 0.029). Age, histology, grade, uterine serosal invasion, adnexal involvement, number of extrauterine sites, and treatment with adjuvant RT predicted for improved survival in univariate analysis. Multivariate analysis revealed that grade, uterine serosal invasion, and treatment with adjuvant RT were independent predictors of survival. Five-year actuarial pelvic control was improved significantly with the delivery of adjuvant RT (74% vs. 49%; p = 0.011). Depth of myometrial invasion and treatment with adjuvant RT were independent predictors of pelvic control in multivariate analysis. Conclusions: Multiple prognostic factors predicting for the outcome of pathologic Stage III endometrial cancer patients were identified in this analysis. In particular, delivery of adjuvant RT seems to be a significant independent predictor for improved survival and pelvic control, suggesting that pelvic RT should be routinely considered in the management of these patients.« less

Alveolar Soft Part Sarcoma of the Female Genital Tract: A Morphologic, Immunohistochemical, and Molecular Cytogenetic Study of 10 Cases With Emphasis on its Distinction From Morphologic Mimics.

Alveolar soft part sarcoma (ASPS) is a morphologically distinctive neoplasm of unknown differentiation that bears a characteristic gene fusion involving ASPSCR1 and TFE3. ASPS can occur in the female genital tract, but is rare. Eleven cases with an initial diagnosis of ASPS at female genital tract sites were evaluated for their morphologic features and immunoprofile using a panel of antibodies (TFE3, HMB45, melan-A, smooth muscle actin, desmin, and h-Caldesmon). In addition, the presence of TFE3 rearrangement and subsequent ASPSCR1-TFE3 fusion were determined by fluorescence in situ hybridization. Ten tumors retained their classification as ASPS based on their morphologic appearance, immunohistochemical profile, and demonstration of ASPSCR1-TFE3 fusion. The remaining case was reclassified as conventional-type PEComa due to its pattern of HMB45, melan-A, and desmin positivity as well as absence of TFE3 rearrangement. Sites of the 10 ASPS were uterine corpus (3), cervix (2), uterus not further specified (2), vagina (2), and vulva (1). The age of the patients ranged from 15 to 68 years (mean 34 y, median 32 y). The tumors demonstrated a spectrum of morphologic features, but all had a consistent immunophenotype of strong TFE3 nuclear expression and lack of muscle (smooth muscle actin, desmin, h-Caldesmon) and melanocytic (melan-A, HMB45) markers, except focal positivity for HMB45 in 1. Follow-up was available for 4 patients ranging from 1 to 35 months (mean 15 mo, median 25 mo) and they were alive and had no evidence of recurrence or metastasis at last follow-up. Distinguishing ASPS from its morphologic mimics, particularly PEComa, is important due to increasingly efficacious targeted agents such as MET-selective and VEGF signaling inhibitors in the former and mTOR inhibition therapy in the latter.

Sarcomas represent a diverse group of malignancies with distinct molecular and pathological features. A better understanding of the alterations associated with specific sarcoma subtypes is critically important to improve sarcoma treatment. Renewed interest in the metabolic properties of cancer cells has led to an exploration of targeting metabolic dependencies as a therapeutic strategy. In this study, we have characterized key bioenergetic properties of human sarcoma cells in order to identify metabolic vulnerabilities between sarcoma subtypes. We have also investigated the effects of compounds that inhibit glycolysis or mitochondrial respiration, either alone or in combination, and examined relationships between bioenergetic parameters and sensitivity to metabolic inhibitors. Using 2-deoxy-D-glucose (2-DG), a competitive inhibitor of glycolysis, oligomycin, an inhibitor of mitochondrial ATP synthase, and metformin, a widely used anti-diabetes drug and inhibitor of complex I of the mitochondrial respiratory chain, we evaluated the effects of metabolic inhibition on sarcoma cell growth and bioenergetic function. Inhibition of glycolysis by 2-DG effectively reduced the viability of alveolar rhabdomyosarcoma cells vs. embryonal rhabdomyosarcoma, osteosarcoma, and normal cells. Interestingly, inhibitors of mitochondrial respiration did not significantly affect viability, but were able to increase sensitivity of sarcomas to inhibition of glycolysis. Additionally, inhibition of glycolysis significantly reduced intracellular ATP levels, and sensitivity to 2-DG-induced growth inhibition was related to respiratory rates and glycolytic dependency. Our findings demonstrate novel relationships between sarcoma bioenergetics and sensitivity to metabolic inhibitors, and suggest that inhibition of metabolic pathways in sarcomas should be further investigated as a potential therapeutic strategy.

Ewing sarcoma is an undifferentiated small-round-cell sarcoma. Although molecular detection of pathognomonic EWSR1-ETS fusions such as EWSR1-FLI1 enables definitive diagnosis, substantial confusion can arise if molecular diagnostics are unavailable. Diagnosis based on the conventional immunohistochemical marker CD99 is unreliable due to its abundant expression in morphological mimics. To identify novel diagnostic immunohistochemical markers for Ewing sarcoma, we performed comparative expression analyses in 768 tumors representing 21 entities including Ewing-like sarcomas, which confirmed that CIC-DUX4-, BCOR-CCNB3-, EWSR1-NFATc2-, and EWSR1-ETS-translocated sarcomas are distinct entities, and revealed that ATP1A1, BCL11B, and GLG1 constitute specific markers for Ewing sarcoma. Their high expression was validated by immunohistochemistry and proved to depend on EWSR1-FLI1-binding to highly active proximal super-enhancers. Automated cut-off-finding and combination-testing in a tissue-microarray comprising 174 samples demonstrated that detection of high BCL11B and/or GLG1 expression is sufficient to reach 96% specificity for Ewing sarcoma. While 88% of tested Ewing-like sarcomas displayed strong CD99-immunoreactivity, none displayed combined strong BCL11B- and GLG1-immunoreactivity. Collectively, we show that ATP1A1, BCL11B, and GLG1 are EWSR1-FLI1 targets, of which BCL11B and GLG1 offer a fast, simple, and cost-efficient way to diagnose Ewing sarcoma by immunohistochemistry. These markers may significantly reduce the number of misdiagnosed patients, and thus improve patient care. PMID:29416716

DNA-aneuploidy may reflect the malignant nature of mesenchymal proliferations and herald gross genomic instability as a mechanistic factor in tumor genesis. DNA-ploidy and -index were determined by flow cytometry in canine inflammatory or neoplastic mesenchymal tissues and related to clinico-pathological features, biological behavior and p53 gene mutational status. Half of all sarcomas were aneuploid. Benign mesenchymal neoplasms were rarely aneuploid and inflammatory lesions not at all. The aneuploidy rate was comparable to that reported for human sarcomas with significant variation amongst subtypes. DNA-ploidy status in canines lacked a relation with histological grade of malignancy, in contrast to human sarcomas. While aneuploidy was related to the development of metastases in soft tissue sarcomas it was not in osteosarcomas. No relation amongst sarcomas was found between ploidy status and presence of P53 gene mutations. Heterogeneity of the DNA index between primary and metastatic sarcoma sites was present in half of the cases examined. Hypoploidy is more common in canine sarcomas and hyperploid cases have less deviation of the DNA index than human sarcomas. The variation in the presence and extent of aneuploidy amongst sarcoma subtypes indicates variation in genomic instability. This study strengthens the concept of interspecies variation in the evolution of gross chromosomal aberrations during cancer development. PMID:24213507

Sarcomas are rare tumors with generally poor prognosis, for which current therapies have shown limited efficacy. Histone deacetylase inhibitors (HDACi) are emerging anti-tumor agents; however, little is known about their effect in sarcomas. By using established and patient-derived sarcoma cells with different subtypes, we showed that the pan-HDACi, ITF2357, potently inhibited in vitro survival in a p53-independent manner. ITF2357-mediated cell death implied the activation of mitochondrial apoptosis, as attested by induction of pro-apoptotic BH3-only proteins and a caspases-dependent mechanism. ITF2357 also induced autophagy, which protected sarcoma cells from apoptotic cell death. ITF2357 activated forkhead box (FOXO) 1 and 3a transcription factors and their downstream target genes, however, silencing of both FOXO1 and 3a did not protect sarcoma cells against ITF2357-induced apoptosis and upregulated FOXO4 and 6. Notably, ITF2357 synergized with Doxorubicin to induce cell death of established and patient-derived sarcoma cells. Furthermore, combination treatment strongly impaired xenograft tumor growth in vivo, when compared to single treatments, suggesting that combination of ITF2357 with Doxorubicin has the potential to enhance sensitization in different preclinical models of sarcoma. Overall, our study highlights the therapeutic potential of ITF2357, alone or in rational combination therapies, for bone and soft tissue sarcomas management.

In this study, a mathematical model of the female circulation during pregnancy is presented in order to investigate the hemodynamic response to the cardiovascular changes associated with each trimester of pregnancy. First, a preliminary lumped parameter model of the circulation of a non-pregnant female was developed, including the heart, the systemic circulation with a specific block for the uterine district and the pulmonary circulation. The model was first tested at rest; then heart rate and vascular resistances were individually varied to verify the correct response to parameter alterations characterising pregnancy. In order to simulate hemodynamics during pregnancy at each trimester, the main changes applied to the model consisted in reducing vascular resistances, and simultaneously increasing heart rate and ventricular wall volumes. Overall, reasonable agreement was found between model outputs and in vivo data, with the trends of the cardiac hemodynamic quantities suggesting correct response of the heart model throughout pregnancy. Results were reported for uterine hemodynamics, with flow tracings resembling typical Doppler velocity waveforms at each stage, including pulsatility indexes. Such a model may be used to explore the changes that happen during pregnancy in female with cardiovascular diseases. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

The bovine pre-implantation embryo secretes bioactive molecules from early development stages, but effects on endometrial function are reported to start only after elongation. Here, we interrogated spatially defined regions of the endometrium transcriptome for responses to a day 7 embryo in vivo. We hypothesize that exposure to an embryo changes the abundance of specific transcripts in the cranial region of the pregnant uterine horn. Endometrium was collected from the uterotubal junction (UTJ), anterior (IA), medial (IM) and posterior (IP) regions of the uterine horn ipsilateral to the CL 7 days after estrus from sham-inseminated (Con) or artificially inseminated, confirmed pregnant (Preg) cows. Abundance of 86 transcripts was evaluated by qPCR using a microfluidic platform. Abundance of 12 transcripts was modulated in the Preg endometrium, including classical interferon-stimulated genes (ISG15, MX1, MX2 and OAS1Y), prostaglandin biosynthesis genes (PTGES, HPGD and AKR1C4), water channel (AQP4) and a solute transporter (SLC1A4) and this was in the UTJ and IA mainly. Additionally, for 71 transcripts, abundance varied according to region of the reproductive tract. Regulation included downregulation of genes associated with proliferation (IGF1, IGF2, IGF1R and IGF2R) and extracellular matrix remodeling (MMP14, MMP19 and MMP2) and upregulation of anti-adhesive genes (MUC1) in the cranial regions of uterine horn. Physical proximity to the embryo provides paracrine regulation of endometrial function. Embryo-independent regulation of the endometrial transcriptome may support subsequent stages of embryo development, such as elongation and implantation. We speculate that successful early embryo-dependent and -independent programming fine-tune endometrial functions that are important for maintenance of pregnancy in cattle. PMID:28423001

2006-01-01

Background Primary extra-osseous osteogenic sarcomas have been reported in many tissues of the body but their occurrence in the breast is extremely rare. It can arise as a result of osseous metaplasia in a pre-existing benign or malignant neoplasm of the breast or as non-phylloides sarcoma from the soft tissue of a previously normal breast. Case presentation A 40 year-old Nigerian woman was clinically diagnosed to have carcinoma of the left breast. The histology report of core-needle biopsy of the mass showed a malignant neoplasm comprising islands of chondroblastic and osteoblastic stromal cells. This report changed the diagnosis from carcinoma to osteogenic sarcoma of the breast. She had a left modified radical mastectomy, however there was significant post surgery skin deficit. A latissimus dorsi musculocutaneous flap was used to cover the anterior chest wall defect. Sections from the mastectomy specimen confirmed the diagnosis of osteogenic sarcoma. She died six months after mastectomy. Conclusion A diagnosis of osteogenic sarcoma of the breast was made based on histology report and after excluding an osteogenic sarcoma arising from underlying ribs and sternum. This is the second documented case of primary osteogenic sarcoma of the breast coming from Nigeria PMID:17156481

Overcoming cetuximab resistance in Ewing's sarcoma by inhibiting lactate dehydrogenase-A.

2016-07-01

Ewing's sarcoma, the second most common type of malignant bone tumor, generally occurs in children and young adults. The current treatment of Ewing's sarcoma comprises systemic anti‑cancer chemotherapy with complete surgical resection. However, the majority of patients with Ewing's sarcoma develop resistance to chemotherapy. The present study revealed an oncogenic role of lactate dehydrogenase‑A (LDHA) in the resistance of Ewing's sarcoma to cetuximab. LDHA was shown to be upregulated at the protein and mRNA level in cetuximab‑resistant Ewing's sarcoma tissues and a cell line. In addition, a link between LDHA‑induced glycolysis and cetuximab resistance in Ewing's sarcoma cells was revealed. Of note, inhibition of LDHA by either small interfering RNA or LDHA inhibitor oxamate significantly re‑sensitized cetuximab‑resistant cells to cetuximab. Combined treatment with LDHA inhibitor and cetuximab synergistically reduced the viability of cetuximab-resistant cells through the suppression of LDHA. The present study revealed a novel mechanism of cetuximab resistance from the perspective of cancer‑cell metabolism and provided a sensitization approach, which may aid in the development of anti-chemoresistance strategies for the treatment of cetuximab-resistant Ewing's sarcoma.

Ewing's sarcoma is a primary malignancy of the bone affecting individuals in the second decade of life. Primary sarcomas of the spine are rare and the occurrence of Primary Ewing's sarcoma in the spine is very rare. Ewing's sarcoma occurring in the spine is divided into two types, Ewing's sarcoma of sacral spine which are very aggressive with poor prognosis and Ewing's sarcoma of the non sacral spine which is an extremely rare occurrence. Patient may present with neurological deficit when the tumour extends into the spinal canal causing spinal cord compression. Magnetic resonance imaging (MRI) is very sensitive in diagnosing the tumour and defining the extent of the tumour. Here we report an 18-year-old boy who presented with back pain and complete paraplegia of two months duration. The MRI gave a differential diagnosis of infective pathology due to the fluid collection in the paraspinal region, followed by primary malignancy as the second diagnosis. Patient underwent posterior spinal decompression and stabilization, and intaoperatively there was significant collection of pus whose culture showed no growth. The histopathology and immunohistochemistry studies confirmed the diagnosis of Ewing's sarcoma and patient was started on combination chemotherapy and radiotherapy.

Background. Soft tissue sarcoma with a hemorrhagic component that cannot be easily diagnosed by needle biopsy is defined here as soft tissue sarcoma with telangiectatic changes (STST). Methods. We retrospectively reviewed clinicopathological data of STST from 14 out of 784 patients (prevalence: 1.8%) with soft tissue sarcoma. Results. Tumors were found mostly in the lower leg. Histological diagnoses were undifferentiated pleomorphic sarcoma (n = 5), synovial sarcoma (n = 5), epithelioid sarcoma (n = 2), and malignant peripheral nerve sheath tumor and fibrosarcoma (n = 1). No history of trauma to the tumor site was recorded in any patient. Needle aspiration transiently reduced the tumor volume, but subsequent recovery of tumor size was observed in all cases. Out of 14 patients, 9 presented with a painful mass. MRI characteristics included intratumoral nodules (64.3%). The local recurrence rate was 14.3%, and the 2-year event-free survival rate was poorer (50%) than that of most sarcomas. Conclusions. STST is unique in its clinicopathological presentation. Painful hematomas without a trauma history, intratumoral nodules within a large hemorrhagic component, and subsequent recovery of tumor size after aspiration are indicative of the presence of STST.

The objective of this retrospective study was to analyze the clinical characteristics and prognosis of clear cell adenocarcinoma (CCA) in the post-diethylstilbestrol (DES) era and to evaluate the feasibility of fertility-preserving treatment. The records of 32 patients with CCAs who were treated at Peking Union Medical College Hospital from August 1986 to June 2012 were retrospectively reviewed. Three of the patients had undergone fertility-preserving treatment. The incidence of CCA among cervical adenocarcinomas was 15.2%. The median age was 38 years: 11 patients (34.4%) were diagnosed before 30 years of age and two (6.3%) after 70 years of age. Ten patients (31.2%) were nulliparous. No patient had been exposed to DES. Twenty-nine patients (90.6%) presented with obvious symptoms, and the cervix appeared abnormal in 26 patients (81.3%). Cervical Papanicolaou (Pap) tests were abnormal in all four patients in whom they were performed (three had high-grade squamous intraepithelial lesions and one had atypical squamous cells of undetermined significance). The distribution by stage was 56.3% stage I, 34.4% stage II, 6.3% stage III, and 3.1% stage IV. Treatments mainly included surgery for patients with stage I to IIA CCA and radiochemotherapy for patients with advanced CCA. The overall 5-year progression-free survival was 72.2%. Patients with stage I to IIA CCA had better 5-year progression-free survival than did patients with stage IIB to IV CCA (81.5% versus 40.0%, P=0.003). The three patients who had undergone fertility-preserving treatment had no recurrences. CCA may also affect adolescents and children without prior DES exposure, who are often misdiagnosed as having functional uterine bleeding. Radiotherapy appears to be effective for local control but to have no effect on distant recurrences. In our study, the prognosis of patients with early-stage CCA, including those who had undergone fertility-preserving treatment, was not inferior to that of patients with other types of cervical adenocarcinoma.

Selection of response criteria for clinical trials of sarcoma treatment.

Schuetze, Scott M; Baker, Laurence H; Benjamin, Robert S; Canetta, Renzo

2008-01-01

Soft tissue sarcomas are a heterogeneous group of malignancies arising from mesenchymal tissues. A large number of new therapies are being evaluated in patients with sarcomas, and consensus criteria defining treatment responses are essential for comparison of results from studies completed by different research groups. The 1979 World Health Organization (WHO) handbook set forth operationally defined criteria for response evaluation in solid tumors that were updated in 2000 with the publication of the Response Evaluation Criteria in Solid Tumors (RECIST). There have been significant advances in tumor imaging, however, that are not reflected in the RECIST. For example, computed tomography (CT) slice thickness has been reduced from 10 mm to < or =2.5 mm, allowing for more reproducible and accurate measurement of smaller lesions. Combination of imaging techniques, such as positron emission tomography with fluorine-18-fluorodeoxyglucose (18FDG-PET) and CT can provide investigators and clinicians with both anatomical and functional information regarding tumors, and there is now a large body of evidence demonstrating the effectiveness of PET/CT and other newer imaging methods for the detection and staging of tumors as well as early determination of responses to therapy. The application of newer imaging methods has the potential to decrease both the sample sizes required for, and duration of, clinical trials by providing an early indication of therapeutic response that is well correlated with clinical outcomes, such as time to tumor progression or overall survival. The results summarized in this review support the conclusion that the RECIST and the WHO criteria for evaluation of response in solid tumors need to be modernized. In addition, there is a current need for prospective trials to compare new response criteria with established endpoints and to validate imaging-based response rates as surrogate endpoints for clinical trials of new agents for sarcoma and other solid tumors.

Case report. To describe a three-dimensional (3D) printed axial vertebral body used in upper cervical spine reconstruction after a C2 Ewing sarcoma resection in an adolescent boy. Ewing sarcoma is a malignant musculoskeletal neoplasm with a peak incidence in adolescents. Cervical spine as the primary site of the tumor has been related to a worse prognosis. Tumor resection is particularly challenging in the atlantoaxial region due to complexity of the anatomy, necessity for extensive resection according to oncological principles, and a lack of specialized implants for reconstruction. 3D printing refers to a process where 3D objects are created through successive layering of material under computer control. Although this technology potentially enables accurate fabrication of patient-specific orthopedic implants, literature on its utilization in this regard is rare. A 12-year-old boy with a C2 Ewing sarcoma underwent a staged spondylectomy. Wide resection of the posterior elements was first performed. Two weeks later, a high anterior retropharyngeal approach was taken to remove the remains of the C2 vertebra. A customized artificial vertebral body fabricated according to a computer model using titanium alloy powder was inserted to replace the defect between C1 and C3. The microstructure of the implant was optimized for better biomechanical stability and enhanced bone healing. Patient had an uneventful recovery and began to ambulate on postoperative day 7. Adjuvant treatment commenced 3 weeks after the surgery. He was tumor-free at the 1-year follow-up. Computed tomography studies revealed evidence of implant osseointegration and no subsidence or displacement of the construct. This is a case example on the concept of personalized precision medicine in a surgical setting and demonstrates how 3D-printed, patient-specific implants may bring individualized solutions to rare problems wherein restoration of the specific anatomy of each patient is a key prognostic factor.
