Breast metastasis from extra-mammary malignancy is rare, constituting 2% of breast tumors. Uterine leiomyosarcoma is a rare soft tissue neoplasm comprising 1% of all uterine malignancies. This report presents the first case of uterine leiomyosarcoma metastasis of the breast. A 44-year-old woman, G4P3AA1, presented with a one-week history of painless bilateral breast lumps. Twelve years previously she had undergone a right salpingo-oophorectomy and hysterectomy for uterine leiomyosarcoma. An excisional biopsy of the breast nodule was performed, and the histopathological study revealed the nodule was composed of spindle cells, typical of breast metastasis with uterine leiomyosarcoma found in the immunohistochemical study. The patient was healthy and symptom free during the 12 month post-operative follow-up period.
Sarcomas are rare and heterogeneous tumours of mesenchymal origin, with over 100 histological subtypes. Paraneoplastic dermatomyositis has rarely been described in sarcoma. This is the first documented case of paraneoplastic dermatomyositis in a patient with metastatic leiomyosarcoma. A 43-year-old female diagnosed with metastatic leiomyosarcoma of unknown primary presented with a mild rash in sun-exposed areas of her face and upper chest, with no other neuromuscular symptoms. This rash resolved with systemic treatment with doxorubicin for metastatic leiomyosarcoma. Imaging assessment confirmed overall stable disease after chemotherapy completion. She presented acutely 2 months later with new onset rash in a shawl-like distribution, periorbital oedema and proximal muscle weakness. Based on the characteristic cutaneous signs and symmetrical proximal muscle weakness, abnormal electromyography and raised skeletal muscle enzymes with a positive anti-transcription intermediary factor-1 gamma antibody result,

N2 - Uterine leiomyosarcoma (LMS) is a highly metastatic smooth muscle neoplasm for which calponin h1 is suspected to have a biological role as a tumor-suppressor. We earlier reported that LMP2-null mice spontaneously develop uterine LMS through malignant transformation of the myometrium, thus implicating this protein as an anti-tumorigenic candidate as well. In the present study, we show that LMP2 may negatively regulate LMS independently of its role in the proteasome. Moreover, several lines of evidence indicate that ...
Soft tissue sarcoma of the intra-abdominal organ is a rare malignant tumor and leiomyosarcoma is its most common histologic type [3]. Regardless of the histologic type, however, surgical resection is considered standard therapy [1]. There have been few studies of distant metastases that occur after the complete resection of a primary leiomyosarcoma. There is no generally accepted treatment for this either, especially for a liver metastasis, although surgery remains the mainstay, because leiomyosarcoma is relatively chemoresistant and radioresistant [4]. There have been few case reports of primary or metastatic leiomyosarcoma of liver [5]. Faraj et al. [4] reported five cases of liver resection for metastatic colorectal leiomyosarcoma, with a median survival of 47 months. Akwari et al. [6] reported 108 cases of intestinal leiomyosarcoma, but with no mention of the management of these metastases. McGrath et al. [7] analyzed 51 cases of primary gastrointestinal sarcoma (virtually all were ...

N2 - The majority of smooth muscle tumors found in the uterus are benign, but uterine leiomyosarcomas (LMSs) are extremely malignant, with high rates of recurrence and metastasis. The development of gynecologic tumors is often correlated with female hormone secretion; however, the development of uterine LMS is not substantially correlated with hormonal conditions, and the risk factors are not clearly understood. The presentation of antigenic peptides by major histocompatibility complex (MHC) class I molecules is important for tumor rejection by cytotoxic T-lymphocytes (CTLs). Such antigenic ...
A 59-year-old woman, diagnosed 7 years ago with uterine leiomyosarcoma (ULMS), developed several intrathoracic, pelvic and lately intra-abdominal and brain metastases. On each occasion, surgical resection was followed by a course of failed chemotherapy. Lately she presented with acute neurological deterioration and focal signs. Magnetic resonance imaging demonstrated two presumed brain parenchymal lesions involving the supratentorial and infratentorial compartments. She underwent surgical resection of the left cerebellar lesion. Histological analysis of the brain specimen confirmed the presence of metastatic ULMS. Leiomyosarcoma of the uterus is an uncommon tumor with a very aggressive course and poor prognosis. Multiple organ metastases from ULMS are an extremely rare condition, and prognostically alarming despite current treatments ...
OBJECTIVE: Trabectedin demonstrated significantly improved disease control in leiomyosarcoma and liposarcoma patients in a global phase 3 trial (NCT01343277). A post hoc analysis was conducted to assess the efficacy and safety of trabectedin or dacarbazine in women with uterine leiomyosarcoma (uLMS), the largest subgroup of enrolled patients (40%). METHODS: Of 577 patients randomized 2:1 to receive trabectedin 1.5mg/m2 by 24-hour IV infusion or dacarbazine 1g/m2 by 20-120-minute IV infusion once every three weeks, 232 had uLMS (trabectedin: 144; dacarbazine: 88). The primary endpoint was overall survival (OS); secondary endpoints were progression-free survival (PFS), objective response rate (ORR), clinical benefit rate (CBR: complete responses+partial responses+stable disease [SD] for at least 18weeks), duration of response (DOR), and safety. RESULTS: PFS for trabectedin was 4.0months compared with 1.5months for dacarbazine (hazard ratio [HR]=0.57; 95% CI 0.41-0.81; P=0.0012). OS was similar ...
1. Introduction. Uterine leiomyosarcoma is an aggressive soft tissue neoplasm occurring in women of all ages, usually presenting with pelvic pain, mass and vaginal bleeding [1] [2] . Rarely, the presenting manifestations are related to hemoperitoneum caused by tumor rupture. The pathogenesis of uterine leiomyosarcoma is controversial. Although most cases of uterine leiomyosarcomas have been thought to arise de novo, several cases of malignant transformation of uterine leiomyoma have been reported [3] -[5] . We herein report an unusual case of hemoperitoneum caused by spontaneous rupture of rapid growing leiomyosarcoma arising in pre-existing leiomyoma of the uterus, which has been monitored over the years.. 2. Case. A 59-year-old postmenopausal woman, para 2, gravida 2, presented deteriorating abdominal distention and pain. She had been annually submitted to transvaginal ultrasound examination for an intramural leiomyoma with calcification (4 cm in diameter) for four years. No alteration visible ...
This is a pilot study of adjuvant therapy for patients with leiomyosarcoma of the uterus that has been completely removed by surgery. Adjuvant therapy means that the tumor (the leiomyosarcoma) has been completely removed by surgery; thus, giving further treatment now is done in hopes of decreasing the chance that the tumor will come back (relapse or recur). The main goal of this study is to show that this series of treatments is safe for patients with your type of tumor.. In this trial you will be getting drugs that have been approved for use in some types of cancer. In this study we wish to see whether the combination of two chemotherapy drugs, docetaxel and gemcitabine can decrease the chance of your tumor, leiomyosarcoma of the uterus, from coming back (relapsing). We will also be looking at the short-term side effects and risks of the drugs given in this combination to patients with leiomyosarcoma that has been completely resected (removed by surgery).. The combination of gemcitabine and ...
Leiomyosarcoma is a malignant mesenchymal tumor originating from smooth muscle cells, which most frequently develops in the myometrium and in the gastro-intestinal tract. Reviewing the international literature, radiation-induced sarcoma arise in 0.035 to 0.2 % of all irradiated patients. Especially in the head and neck region, radiation-induced leiomyosarcoma is an extremely rare lesion. The authors report a case of a radiation-induced leiomyosarcoma of the tonsillar region of the oropharynx in a 51-year-old male patient, who had undergone radiation therapy of this region 38 years before. The lesion was treated by radical surgery. Diagnostic steps, histological presentation and therapy are described in detail and the literature concerning radiation induced malignancies in general as well as radiation induced leiomyosarcoma in particular is reviewed. The highlights of this case are an extremely uncommon location and a rare pathological entity of radiation induced malignancies.

Increased awareness of leiomyosarcoma (LMS) risk during myomectomy or hysterectomy is essential. Objective and correct reasoning should prevail on any decision regarding the extent and type of surgery to employ. The anticipated risk of a sarcoma after myoma or uterus morcellation is low, and the frequency of leiomyosarcoma especially in women below the age of 40 is very rare. The prevalence data has a wide range and is therefore not reliable. The European Society of Gynaecological Endoscopy (ESGE) initiated a survey among its members looking into the frequency of morcellated leiomyosarcoma after endoscopic surgery. The ESGE Central office sent 3422 members a structured electronic questionnaire with multiple answer choices for each question. After 3 months, the answers were classified with a unique number in the EXCEL spread sheet. Statistical analysis was done using the SPSS v.18. Out of 3422 members, 294 (8.6%) gynaecologists replied to the questionnaire; however, only 240 perform myomectomies by

Discussing the premise of the study, lead investigator Frédéric Amant (Leuven Cancer Institute, Belgium) commented: We wanted to generate a clear view on the presence of targetable proteins in all subtypes of uterine sarcomas, with the aim of improving treatment options for these patients. Identifying biomarkers is crucial because novel treatments are expensive, underscoring the importance of patient selection.. The investigating team assessed five proteins in 288 samples of uterine sarcoma. In terms of subtypes, these samples included 157 leiomyosarcomas, 52 benign uterine stromal tumors and 41 normal uterine tissues. The remaining samples consisted of endometrial sarcomas, adenosarcomas and other undifferentiated types of uterine sarcoma.. These analyses uncovered that activated P-S6S240 is more often found expressed in high-grade tumors when compared with low-grade tumors - 32% vs 9%, respectively. Given that P-S6S240 is involved in the PI3K/mTOR cell signaling pathway, the team went on ...

Uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. Leiomyosarcoma (LMS) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. Herein, we present a case of LMS with unusual macroscopic features. The patient was a 61-year-old woman with LMS, which consisted of a large cystic mass (88×136 mm), containing six liters of brownish fluid on the right side of the pelvis and abdomen. The fundus of the uterus was ruptured by the solid part of the tumor. For treatment, total hysterectomy, salpingo-oophorectomy and the optimal resection of tumoral parts were carried out. Overall, the distinctive biological behavior and poor overall survival of uterine sarcoma challenge the post-operative management of this tumor. According to the one-year follow-up, the patient was disease-free. Unfortunately, no further information is at hand beyond this period.
In situ hybridization showed EBV genomes in all muscle cells of the five leiomyosarcomas and the two leiomyomas from the six HIV-infected children. Quantitative PCR demonstrated strikingly high levels of EBV in tumor tissue, with as many as 4.3 genome copies per cell. Two colonic leiomyosarcomas obtained from different sites at different times from one patient contained different episomal EBV clones, signifying the presence of distinct monoclonal EBV-related tumors. We found biclonal EBV infection in the leiomyosarcoma of another patient. No EBV was detected in normal muscle or tumor specimens from HIV-negative patients. Immunostaining for the EBV receptor was strongly positive in six of the seven leiomyomas and leiomyosarcomas from the patients with AIDS. Conclusions: ...

Shortly after the operation, Dr Reed learned that she had a uterine leiomyosarcoma and that morcellation had advanced it to stage IV. She underwent cytoreduction and hypothermic intraperiotoneal chemotherapy followed by six rounds of systemic chemotherapy. MRI and CT scans indicated she was cancer free.. She and her family moved from Needham, Massachusetts, to Yardley, Pennsylvania, and by the end of 2014, she had recovered well enough to start working part time at the Hospital of the University of Pennsylvania. However, the leiomyosarcoma still lurked in her body, requiring a surgery to remove a tumor behind her left kidney in February 2015, with radiation treatment afterwards. More metastasis and more procedures, some experimental, followed.. We all knew the odds were against her, said Dr Zuckerman, but Hooman and Amy were both determined to beat the odds. They made it seem possible.. The end almost came in April when Dr Reed went into pulseless electrical activity cardiac arrest. As Dr ...

Although the patient did not have any known risk factors, PE was assumed and anticoagulant therapy was initiated, while additional testing was being performed. A pulmonary scintigraphy was requested, which confirmed the absence of left lung perfusion and no changes in the right lung. Right heart catheterization confirmed severe pulmonary hypertension. However, both D-dimer and Doppler ultrasonography of the lower limbs were negative. Thrombophilia, inflammatory markers, tumor markers, and autoimmunity markers were also negative. After 3 months of anticoagulation, the patients dyspnea persisted. A follow-up CT angiogram showed an increase in the filling defect in the right pulmonary artery, along with isolated pulmonary infiltrates.. In view of his poor progress, a chest MRI with contrast medium was requested, showing a mediastinal mass with the same intensity as the muscles in T1, and hyperintense in T2 due to contrast uptake, suggestive of leiomyosarcoma of the pulmonary artery (Fig. 1b).

Background: Soft tissue sarcomas are heterogeneous and a major complication in their management is that the existing classification scheme is not definitive and is still evolving. Leiomyosarcomas, a major histologic category of soft tissue sarcomas, are malignant tumours displaying smooth muscle differentiation. Although defined as a single group, they exhibit a wide range of clinical behaviour. We aimed to carry out molecular classification to identify new molecular subgroups with clinical relevance. Methods: We used gene expression profiling on 20 extra-uterine leiomyosarcomas and cross-study analyses for molecular classification of leiomyosarcomas. Clinical significance of the subgroupings was investigated. Results: We have identified two distinct molecular subgroups of leiomyosarcomas. One group was characterised by high expression of 26 genes that included many genes from the sub-classification gene cluster proposed by Nielsen et al. These sub-classification genes include genes that have ...

Abstract: Resistance to chemotherapeutic agents and radiotherapy has kept surgery the primary treatment of uterine leiomyosarcoma (ULMS). In search of leads for potential therapeutic targets, array CGH (aCGH) was used to obtain a genomewide pattern of ULMS-specific genetic imbalances and to define the affected biological processes. Fine-resolution genomewide aCGH analysis was performed using customised 16K cDNA microarrays on 18 primary ULMS cases. Furthermore, patterns of DNA copy number changes were assessed for associations with clinical parameters, i.e., tumour grade, tumour size and patient status at last follow-up. Our aCGH results demonstrated extensive DNA copy number changes in all chromosomes. Of the 10,590 gene loci included in the analysis, 4,387 were found to be affected by DNA copy number gains and 4,518 by DNA copy number losses in at least one case. Further analyses revealed that 231 of these were commonly gained, and 265 lost in at least 20% of the cases. The gains affected loci ...

Leiomyosarcoma (LMS) of inferior vena cava is a rare and aggressive tumor, arising from the smooth muscle cells in the vessel wall. A large complete surgical resection is the essential treatment. The need of vascular reconstruction is not always mandatory. It s above all to understand the place of the reconstruction with artificial vascular patch prosthetics of vena cave after a large resection of the tumor. We rapport two cases of LMS of inferior vena cava in two women who underwent successful large resection of tumor and lower segment of inferior vena cava. In first case, reconstruction of the inferior vena cava was not performed because of the development of venous collaterals derivation. In the second case reconstruction was done using Dacron interposition graft. The necessity of a large resection in management of primary leiomyosarcoma of vena cave makes sometimes unavoidable the sacrifice of a portion of the vena. Indeed, a better comprehension of the development of venous derivation may render

Smooth muscle tumors of the uterus are a diagnostically challenging group of tumors. Molecular surrogate markers reliably distinguishing between benign and malignant tumors are not available. Therefore, the diagnosis is based on morphologic criteria. The aim was to investigate a well-characterized group of challenging uterine smooth muscle tumors consisting of 20 leiomyomas, 13 leiomyomas with bizarre nuclei, and 14 leiomyosarcomas for copy number alterations, MED12 mutations and FH deletions to search for potential diagnostically useful surrogate markers. MED12 mutations were detected in 47, 15, and 25% of leiomyomas, leiomyomas with bizarre nuclei and leiomyosarcomas, respectively. MED12 mutations in leiomyomas with bizarre nuclei were detected outside the hotspot region. FH-deletions were seen in 27, 30.8, and 25% of leiomyomas, leiomyomas with bizarre nuclei and leiomyosarcomas, respectively.

Ninety-six assessable patients with advanced or recurrent uterine sarcomas, who were no longer controllable with surgery and radiotherapy, and who had not received prior chemotherapy were treated with cisplatin 50 mg/m2 intravenously every 3 weeks. Of 63 cases with mixed mesodermal tumors, five complete responses (CRs; 8%) and seven partial responses (PRs; 11%) were observed (95% confidence interval [CI], 10.3% to 30.9%). Of 33 patients with leiomyosarcoma, one PR (3%) was observed (95% CI, .1% to 15.8%). Adverse effects included leukopenia (23%), nausea and vomiting (73%), and mild azotemia (42%). No patients experienced life-threatening toxicity. Cisplatin has definite activity when given at the dose and schedule that we tested for patients with mixed mesodermal sarcomas who have not received prior chemotherapy, but has little activity in patients with leiomyosarcoma ...
10 mitosis per high power field. In contrast a uterine leiomyoma as a benign lesion would have < 5 mitosis per high power field. Therapy is based on staging and patient condition and utilizes one or more of the following approaches. Surgery is the mainstay of therapy if feasible involving total abdominal hysterectomy with bilateral salpingo-oophorectomy. Other approaches include radiation therapy, chemotherapy, and hormonal therapy. Prognosis is relatively poor. Uterine sarcoma are rare, out of all malignancies of the uterine body only about 4% will be uterine sarcomas. Generally, the cause of the lesion is not known, however patients with a history of pelvic radiation are at higher risk. Most tumors occur after menopause. Women who take long-term tamoxifen are at higher risk. Uterine fibroids Leiomyosarcoma Zagouri F, Dimopoulos AM, Fotiou S, Kouloulias V, Papadimitriou CA (2009).

Gastrointestinal stromal tumor (GIST) is a rare malignancy of mesenchymal origin. The true incidence of GIST has historically been underestimated as these tumors were commonly misclassified as leiomyomas, leiomyosarcomas, and leiomyoblastomas.1 The term gastric stromal tumor was first proposed in 1983 to describe gastric wall tumors that lacked the ultrastructural features of smooth muscle cells and the immunohistochemical characteristics of Schwann cells.2 Mazur and Clark2 examined 28 gastric wall tumors that were originally classified by light microscopy as leiomyomas or leiomyosarcomas and, using electron microscopy, determined that some of these tumors lacked features expected in cells derived from smooth muscle. Additionally, using immunohistochemistry to identify the neuroectoderm marker S-100, they found that the majority of tumors failed to show evidence of a nerve sheath origin. They postulated that this subset of tumors that did not appear from a smooth muscle origin or peripheral ...

Due to propensity for arising in the retroperitoneum, close to or in association with the inferior vena cava, leiomyosarcomas may cause obstruction of the IVC with Budd-Chiari (upper IVC), renal failure (middle IVC) or lower limb oedema (lower IVC). More commonly it present with a mass lesion. Local recurrence and distant metastases are common with retroperitoneal sites; superficial sites are often curable due to smaller size at presentation; and those arising in deep tissues are of intermediate behaviour.. ...

Cytologic features: Smears are relatively cellular containing fragments of spindle-shaped cells. Cells have relatively bland nuclei and wispy cytoplasm with long extensions. No mitoses or necrosis identified. On cell block, immunostains were performed to show the neoplastic cells are positive for c-Kit, DOG1 and SMA; and negative for S100 and desmin.. Differential diagnosis: Schwannoma appears as large cohesive fragments on smears. The neoplastic cells are bland with wavy (fishhook) nuclei and pointed ends and filamentous cytoplasm. Nuclear palisading may be recognized. Although leiomyoma of the gastrointestinal tract usually involves the esophagus, the distinction between a smooth muscle tumor and a GIST relays on immunohistochemistry of c-Kit, DOG1, Desmin and SMA. Leiomyosarcoma would have more significant nuclear pleomorphism, atypia and mitosis as well as less prominent vascular pattern than GIST.. ...
This randomized phase 3 study compared the efficacy and safety of evofosfamide (EVO) plus doxorubicin (D) with D alone in patients with locally advanced unresectable or metastatic STS previously untreated with chemotherapy for advanced disease. Patients on EVO+D could receive EVO alone after 6 cycles. The primary end point was overall survival (OS). Secondary end points were progression-free survival (PFS), overall response rate (ORR), and safety.. From September 2011 to January 2014, 640 patients were randomized: 317 EVO+D, 323 D; 621 patients were treated. Baseline characteristics were balanced. The median age was 59 years (range, 18-89 years); 57% ECOG 0; 36% leiomyosarcoma, 17% liposarcoma, and 12% undifferentiated pleomorphic sarcoma.. The primary end point, OS, was not met. Median OS was 18.4 months for EVO+D and 19.0 months for D alone. ORR was 28% and 18%, respectively. Median PFS was 6.3 months and 6.0 months, respectively. The most common grade 3 to 5 adverse events (AEs) were anemia ...

Hello Michael,. I just read your post. I also am currently being treated for a rare and aggressive sarcoma called Leiomyosarcoma of the upper left thigh. I had my first round of chemo Doxorubicin, Ifosfamide, and Mesna in August of 2012 then again 21 days later. On October 2, 2012 I had a very large (15x8x6 cm) tumor removed from my thigh along with one and a half of my quadrant muscles, and damages soft tissue. Fortunately pathology returned negative margins. Then I started 32 days of radiation in November - finishing just in time for Christmas on December 22, 2012. I had extreme reactions to radiation because the radiated area was so large. I feel truly fortunate to have had 6 weeks off - no treatment. I am going back in the hospital this coming Tuesday, February 12, 2013 for the 3rd of what we hope will be 4 cycles of chemotherapy.. I stronly recommend that you get another opinion, and even a 3rd and 4th. Im not sure where youre located, but my Orthopedic Oncologist is Dr. Philip Krueger ...
Discussion. Leiomyoma of deep soft tissue is exceptionally rare compared to its malignant counterpart. Leiomyoma is a benign, usually solitary tumour of smooth muscle origin commonly involving the organs of the body composed of smooth muscle such as the uterus, urogenital tract and gastrointestinal tract.1,2 When found in soft tissue, it usually involves the dermis and subcutaneous layer. It very rarely affects the deep soft tissue.1,2,13 The deep leiomyomas have been found most frequently within skeletal muscle originating from vessels with unstriated muscle. They are more common in adults and rarely described in children.13 The tumour usually shows calcification in 58% of cases.13 The largest tumour described in children measured 7.5 cm.6. The radiological appearance can resemble various familiar conditions seen in orthopaedics and the diagnosis can be challenging.. Leiomyoma involving skeletal muscles of the extremities in children has been reported in nine children only, viz: thigh muscles = ...

Hello and thank you for visiting my fundraising page. I will be paddling again this year in the Catalina Classic, as a part of the Ocean of Hope team. The Classic is a 32 mile paddleboard race across the Catalina Channel. As most of you know, last years race did not go too well. With strong winds, large swells and my lack of experience in the sport, I struggled for nine and a half hours to finish the race, but with a little luck, I made it. Im back again this year to challenge the Catalina Classic one more time; not to try to better my time, but to once again join the fight against cancer, raising much needed support for the Sarcoma Alliance. The fight against cancer continues to be a difficult one. Now 5 years after Suzanne lost her fight to synovial sarcoma and with the sudden and shocking loss of aunt Mercedes to leiomyosarcoma, the importance of the services provided by the Sarcoma Alliance and groups like it, could not be more clear. The passing of Mercedes Capati, my wife Rias dearly ...
TY - JOUR. T1 - Primary solid hepatic sarcoma. Diagnosis by cytological puncture. AU - Ruiz Valverde, M. P.. AU - Vargas, V.. AU - Tallada, N.. AU - Esteban, R.. AU - Guardia, J.. PY - 1991/1/1. Y1 - 1991/1/1. N2 - The clinical case of a 56 year old patient who developed a grafted hepatic tumoration on a year after diagnosis of liver cirrhosis of alcoholic etiology is reported. Diagnosis of the mass was made by fine needle aspiration punction ecographically guided obtaining a cellular block which, upon anatomopathological study, revealed the presence of a malignant mesenchymal tumor; a leiomyosarcoma. Not only is this type of primary hepatic tumor rare but its appearance on a liver of alcoholic cirrhosis is also of interest. It is much more common to find primary hepatic tumors of epithelial origin, concretely hepatocarcinomas. The value of this finding is discussed with the importance of the ecographically guided punction enabling the establishment of a precise histological diagnosis being ...
Primary renal sarcoma is a rare tumor that accounts for approximately 1% - 3% of malignant renal neoplasms, and leiomyosarcoma is the most common subtype, which accounts for 50% - 60% of all renal sarcomas (3). Primary RSS, a mesenchymal tumor occurring mainly in adults, is an extremely rare neoplasm (3, 4). It was described firstly by Argani et al. in 1999 and since then, approximately 120 cases of RSS have been reported in the literature (2, 5, 6). RSS can be initially misdiagnosed as renal cell carcinoma because of similar clinical characteristics (7). In previous reports, age of RSS patients ranged from 17 to 78 years (median: 36.5 years), and no gender predominance was observed (8, 9). Patients with RSS might be asymptomatic or suffer from abdominal pain, hematuria, fever, and dysuria (10). All sorts of presenting clinical characteristics may arise based on location and size of the lesion.. CT and MRI imaging provided useful information for determining the extent and invasiveness of the ...

ABSTRACT: Morcellation is a surgical technique used to reduce the size of the uterus or myomas by creating smaller pieces to allow the tissue to be removed through small incisions or with laparoscopic instruments. Open (uncontained) morcellation of the uterus and myomas has been scrutinized because of the possible spread of an unsuspected leiomyosarcoma while using a power morcellator during a hysterectomy or myomectomy for presumed symptomatic uterine leiomyomas. Before considering open morcellation of the uterus, a woman should be evaluated to determine if she is at increased risk of malign... ...

BACKGROUND. Small intestinal tumors are uncommon in cats and dogs. The majority of intestinal tumors are malignant and include lymphoma (especially cats), adenocarcinoma and leiomyosarcoma. The metastatic risk for malignant tumors is moderate with metastasis to the regional lymph nodes, liver and lungs relatively common.. DIAGNOSIS. Ultrasonography is recommended for both diagnosis and clinical staging. Other diagnostic tests include contrast radiographs (barium study) and endoscopy. A preoperative diagnosis is sometimes not possible and surgery may be required to both diagnose and treat gastric tumors.. CLINICAL STAGING. An abdominal ultrasound is recommended to check for metastasis to the regional lymph nodes and liver. Chest radiographs or CT scans are done to check for metastasis to the lungs.. TREATMENT. The majority of intestinal tumors are treated with surgical resection with wide margins (3-5 cm) and end-to-end anastomosis. Lymphoma can be treated with multiagent chemotherapy protocols, ...
Class: Chemotherapy. Generic Name: Trabectedin. Trade Name: Yondelis®. For which conditions is this drug approved? Yondelis is approved for the treatment of adults with liposarcoma or leiomyosarcoma that cannot be treated with surgery or has spread to other areas of the body and for patients who have received treatment with certain other medicines.. What is the mechanism of action? Yondelis helps fight cancer by preventing the tumor cells from multiplying and also kills cancer cells. It works by blocking certain types proteins (transcription factors) that are involved the copying and sending of tumor cell DNA.. How is Yondelis typically given (administered)? Youll receive Yondelis once every three weeks through an infusion into a large vein in your body. Each infusion will take 24 hours. Your doctor will also give you a steroid medicine to help reduce your risk of getting certain side effects before each infusion.. How are patients typically monitored? While youre receiving treatment with ...

Our series confirms that these smooth muscle tumors are EBV related (eight of eight were EBER positive) and has similar histopathology characteristics to previous reports (12). All our patients were Chinese, suggesting an ethnic predisposition to the tumor as our study population, although predominantly Chinese, included patients of races such as Malays and Indians. In contrast to a predominantly Western paediatric population described in previous reports, all of our patients were adults. Our results indicate that the disease does not exhibit an age-specific predilection. Rather, the likelihood of developing of EBV+SMT may be related to the degree of immunosupresssion induced.. EBV+SMT may arise long after renal transplant (from 24-156 months), which is consistent with a previous report (13). These tumors were indolent in behavior, even in advanced, multifocal disease. Seven of our patients are still alive, five with radiological evidence of slowly progressive disease. The low expression of the ...
In young women with low-grade leiomyosarcomas (LMS) that have not spread beyond the uterus, the surgeon may-rarely--be able to leave the uterus, fallopian tubes, and ovaries in place, and instead remove only the tumor along with a rim of the normal tissue around it. This approach is not standard treatment, so it is not often offered. It may rarely be a choice for some women who want to still be able to have children after their cancer has been treated. This option has risks, however, so women considering this surgery need to discuss the possible risks and benefits with their gynecologic oncologist before making a decision. It may also be possible to leave a young womans ovaries in place (but remove the uterus and fallopian tubes), since it isnt clear that this will lead to worse outcomes. Still, this is not a standard treatment, and you should discuss the possible risks and benefits with your doctor. In either case, close follow-up is important, and additional surgery may be needed if the ...
Most modern LMSs are web-based. There are a variety of integration strategies for embedding content into LMSs, including AICC, xAPI (also called Tin Can), SCORM (Sharable Content Object Reference Model)[16] and LTI (Learning Tools Interoperability). LMSs were originally designed to be locally hosted on-premise, where the organization purchases a license to a version of the software, and installs it on their own servers and network. Many LMSs are now offered as SaaS (software as a service), with hosting provided by the vendors.[17] Through LMS, teachers may create and integrate course materials, articulate learning goals, align content and assessments, track studying progress, and create customized test for students. LMS allows the communication of learning objectives, and organize learning timelines. LMS leverage is that it delivers learning content and tools straight to learners, and it can also reach marginalized groups through special settings. Such systems have built-in customizable ...
