    Full Text Available Pediatric sarcomas are a heterogeneous group of malignant tumors of bone and soft tissue origin. Although more than 100 different histologic subtypes have been described, the majority of pediatric cases belong to the Ewing’s family of tumors, rhabdomyosarcoma and osteosarcoma. Most patients that present with localized stage are curable with surgery and/or chemotherapy; however, those with metastatic disease at diagnosis or those who experience a relapse continue to have a very poor prognosis. New therapies for these patients are urgently needed. Immunotherapy is an established treatment modality for both liquid and solid tumors, and in pediatrics, most notably for neuroblastoma and osteosarcoma. In the past, immunomodulatory agents such as interferon, interleukin-2, and Liposomal-muramyl  tripeptide phosphatidyl-ethanolamine (L-MTP have been tried, with some activity seen in subsets of patients; additionally, various cancer vaccines have been studied with possible benefit. Monoclonal antibody therapies against tumor antigens such as disialoganglioside GD2 or immune checkpoint targets such as CTLA4 and PD-1 are being actively explored in pediatric sarcomas. Building on the success of adoptive T cell therapy for EBV-related lymphoma, strategies to redirect T cells using chimeric antigen receptors and bispecific antibodies are rapidly evolving with potential for the treatment of sarcomas. This review will focus on recent preclinical and clinical developments in targeted agents for pediatric sarcomas with emphasis on the immunobiology of immune checkpoints, immunoediting, tumor microenvironment, antibody engineering, cell engineering, and tumor vaccines. The future integration of antibody based and cell based therapies into an overall treatment strategy of sarcoma will be discussed.

    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.

    Purpose: Childhood cancer survivors have an increased risk of secondary sarcomas. To better identify those at risk, the relationship between therapeutic dose of chemotherapy and radiation and secondary sarcoma should be quantified. Methods and Materials: We conducted a nested case-control study of secondary sarcomas (105 cases, 422 matched controls) in a cohort of 14,372 childhood cancer survivors. Radiation dose at the second malignant neoplasm (SMN) site and use of chemotherapy were estimated from detailed review of medical records. Odds ratios (ORs) and 95% confidence intervals were estimated by conditional logistic regression. Excess odds ratio (EOR) was modeled as a function of radiation dose, chemotherapy, and host factors. Results: Sarcomas occurred a median of 11.8 years (range, 5.3–31.3 years) from original diagnosis. Any exposure to radiation was associated with increased risk of secondary sarcoma (OR = 4.1, 95% CI = 1.8–9.5). A dose–response relation was observed, with elevated risks at doses between 10 and 29.9 Gy (OR = 15.6, 95% CI = 4.5–53.9), 30–49.9 Gy (OR = 16.0, 95% CI 3.8–67.8) and >50 Gy (OR = 114.1, 95% CI 13.5–964.8). Anthracycline exposure was associated with sarcoma risk (OR = 3.5, 95% CI = 1.6–7.7) adjusting for radiation dose, other chemotherapy, and primary cancer. Adjusting for treatment, survivors with a first diagnosis of Hodgkin lymphoma (OR = 10.7, 95% CI = 3.1–37.4) or primary sarcoma (OR = 8.4, 95% CI = 3.2–22.3) were more likely to develop a sarcoma. Conclusions: Of the risk factors evaluated, radiation exposure was the most important for secondary sarcoma development in childhood cancer survivors; anthracycline chemotherapy exposure was also associated with increased risk.

    Full Text Available Kaposi Sarcoma is a rare vascular neoplasm of the skin and mucosal membranes associated with human herpes virus 8 (HHV-8 infection. It is usually associated with severe suppression of the immune system, e. g. in the setting of human immune deficiency virus (HIV infection and aquired immune deficiency syndrome (AIDS. Here we present a case of a 33 year old female, who was diagnosed to be HIV-positive in march 2015. On physical examination petechial bleedings were recognized at the hard palate. The biopsy specimen showed an ulcerated squamous mucosa with granulation tissue. Single swollen endothelia within angulated vessels were suspicious for a vascular tumor. Immunohistochemical evaluation revealed proliferating endothelia positive for HHV-8. Thus, the diagnosis of a Kaposi Sarcoma within granulation tissue at the hard palate was made. The diagnosis of Kaposi Sarcoma can be very difficult, especially in the setting of concurrent inflammation. Immunohistochemical workup is therefore recommended and necessary to verify the diagnosis of Kaposi Sarcoma.

    Bone sarcoma as a second malignancy is rare but highly fatal. The present knowledge about radiation-absorbed organ dose-response is insufficient to predict the risks induced by radiation therapy techniques. The objective of the present study was to assess the treatment-induced risk for bone sarcoma following a childhood cancer and particularly the related risk of radiotherapy. Therefore, a retrospective cohort of 4,171 survivors of a solid childhood cancer treated between 1942 and 1986 in France and Britain has been followed prospectively. We collected detailed information on treatments received during childhood cancer. Additionally, an innovative methodology has been developed to evaluate the dose-response relationship between bone sarcoma and radiation dose throughout this cohort. The median follow-up was 26 years, and 39 patients had developed bone sarcoma. It was found that the overall incidence was 45-fold higher [standardized incidence ratio 44.8, 95 % confidence interval (CI) 31.0-59.8] than expected from the general population, and the absolute excess risk was 35.1 per 100,000 person-years (95 % CI 24.0-47.1). The risk of bone sarcoma increased slowly up to a cumulative radiation organ absorbed dose of 15 Gy [hazard ratio (HR) = 8.2, 95 % CI 1.6-42.9] and then strongly increased for higher radiation doses (HR for 30 Gy or more 117.9, 95 % CI 36.5-380.6), compared with patients not treated with radiotherapy. A linear model with an excess relative risk per Gy of 1.77 (95 % CI 0.6213-5.935) provided a close fit to the data. These findings have important therapeutic implications: Lowering the radiation dose to the bones should reduce the incidence of secondary bone sarcomas. Other therapeutic solutions should be preferred to radiotherapy in bone sarcoma-sensitive areas.

    The rising incidence of second malignant neoplasms after childhood cancer, whilst due in part to increasing numbers of survivors, is also thought to be related to increasingly more intensive combined modality treatment schedules. Three illustrative cases are reported in which radiation therapy in childhood for the first cancer is thought to have been a significant aetiological factor in the pathogenesis of the second malignancy (which in all three patients was an osteogenic sarcoma).

    The authors report their experience with an unusual case of intracerebral sarcoma of meningeal cell origin in an 8 1/2-year-old girl. This tumor occurred 6 1/2 years after cranial irradiation at relatively low dosage (2200 rads) had been delivered to the head in the course of a multimodality treatment for acute lymphocytic leukemia. The tumor recurred approximately 10 months after the first surgical intervention. Macroscopic total excision of the recurrent growth followed by whole-brain irradiation (4500 rads) failed to eradicate it completely and local recurrence prompted reoperation 18 months later. This complication of treatment in long-term childhood leukemia survivors is briefly discussed, as well as the pathology of meningeal sarcomas

    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.

    2011-01-01

    Purpose: To compare patterns of long-term deaths due to secondary carcinomas, sarcomas, and hematological malignancies occurring after childhood cancer in a cohort of patients followed over a median of 28 years. Methods and Materials: The study included 4,230 patients treated at eight institutions, who were at least 5-year survivors of a first cancer, representing 105,670 person-years of observation. Complete clinical, chemotherapeutic, and radiotherapeutic data were recorded, and the integral radiation dose was estimated for 2,701 of the 2,948 patients who had received radiotherapy. The integral dose was estimated for the volume inside the beam edges. The causes of death obtained from death certificates were validated. Results: In total, 134 events were due to second malignant neoplasm(s) (SMN). We found that the standardized mortality ratio decreased with increasing follow-up for second carcinomas and sarcomas, whereas the absolute excess risk (AER) increased for a second carcinoma but decreased for second sarcomas. There was no clear variation in SMN and AER for hematological malignancies. We found a significant dose-response relationship between the radiation dose received and the mortality rate due to a second sarcoma and carcinoma. The risk of death due to carcinoma and sarcoma as SMN was 5.2-fold and 12.5-fold higher, respectively, in patients who had received a radiation dose exceeding 150 joules. Conclusions: Among patients who had received radiotherapy, only those having received the highest integral radiation dose actually had a higher risk of dying of a second carcinoma or sarcoma.

    Full Text Available Abstract Sarcomas account for over 20% of all pediatric solid malignant cancers and less than 1% of all adult solid malignant cancers. The vast majority of diagnosed sarcomas will be soft tissue sarcomas, while malignant bone tumors make up just over 10% of sarcomas. The risks for sarcoma are not well-understood. We evaluated the existing literature on the epidemiology and etiology of sarcoma. Risks for sarcoma development can be divided into environmental exposures, genetic susceptibility, and an interaction between the two. HIV-positive individuals are at an increased risk for Kaposi’s sarcoma, even though HHV8 is the causative virus. Radiation exposure from radiotherapy has been strongly associated with secondary sarcoma development in certain cancer patients. In fact, the risk of malignant bone tumors increases as the cumulative dose of radiation to the bone increases (p for trend

    Ewing's sarcoma family is a group of small round cells tumors. The aim of this study is to evaluate clinicopathologic characteristics and outcome of Ewing's sarcoma in children and adolescents in Yazd, Iran. All patients under 19 years with documented pathology of Ewing's sarcoma family tumor who referred to Shahid Ramazanzadeh Radiotherapy center between 2002 to 2010 were enrolled in this retrospective study. Overall survival and disease free survival and prognostic factors were evaluated. Among approximately 80,000 patients who referred to Shahid Sadoughi pathology department, over an 8-year period, the total number of patients with Ewing sarcoma was 32, of which, 18 cases were under the age 19 . The mean age was 13.72 years. Five patients (27.8%) had metastatic disease at the time of diagnosis. Complete response had been achieved in 8 (44.4%) of the patients. Local recurrence occurred in 4 (22.2%) of the patients. During the follow up 13 (72.2%) of the patients showed metastases. The mean overall survival was 34.79 months (95% CI: 22.27-47.32) .One, two, four and five year survival was 72%, 39%, 25% and 17% respectively. Complete remission occurred in 10 patients (63.6%). A trend of better overall survival was found in these patients (p=0. 55). When the brain and bone metastases occurred, the overall survival decreased significantly (p=0. 003 ). The overall survival rate of Ewing's sarcoma is very low in comparison with other parts of the world.

    REASONS: Schizophrenia is typically an adult neurodevelopmental disorder that has its antecedents in childhood and adolescence. Little is known about disorders "usually first diagnosed in infancy, childhood and adolescence" (e.g., childhood-onset disorders) in "prodromal" teens at heightened clinical risk for psychotic disorder. Childhood-onset disorders were prevalent in putatively prodromal teens, including anxiety and disruptive disorders, attention-deficit/hyperactivity disorder (ADHD), and, surprisingly, elimination disorders. These may reflect developmental antecedents in psychotic disorders such as schizophrenia. A case series of 9 teens (ages 13-17) identified as prodromal to psychosis were evaluated with the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL). Childhood-onset diagnoses commonly endorsed (threshold or subthreshold) included ADHD (5/9), oppositional defiant disorder (5/9), enuresis or encopresis (4/9), conduct disorder (2/9), separation anxiety (3/9), and transient tic disorder (2/9). Enuresis was identified in 3 of the 4 older teens (ages 15-17). An understanding of the childhood-onset disorders that occur in teens at risk for psychotic illnesses, such as schizophrenia, can shed light on the pathophysiology of schizophrenia and potentially inform early identification and intervention.

They may arise as primary tumors in either bone or soft tissue, with approximately 11,280 soft tissue tumors and 2,650 bone tumors diagnosed each year in the United States. There are at least 50 different subtypes of soft tissue sarcoma, with new ones described with ever-increasing frequency. One way to look at sarcomas is to divide them into categories on the basis of their genetic make-up. One group of sarcomas has an identifiable, relatively simple genetic signature, such as the X:18 translocation seen in synovial sarcoma or the 11:22 translocation seen in Ewing's sarcoma. These specific abnormalities often lead to the presence of fusion proteins, such as EWS-FLI1 in Ewing's sarcoma, which are helpful as diagnostic tools and may become therapeutic targets in the future. Another group of sarcomas is characterized by complex genetic abnormalities as seen in leiomyosarcoma, osteosarcoma, and undifferentiated sarcoma. It is important to keep these distinctions in mind when contemplating the development of targeted agents for sarcomas.

    Full Text Available Urinary incontinence in children can be originated mostly from urinary tract infections, but constipation, neurologic disorders, obstruction and tumors can also be considered among other causes. Pelvic tumors may present with back pain, bladder or bowel dysfunction. Ewing's sarcoma is among the small round-cell tumors of the childhood and potentially can arise from any part of the body. Here, we report an 11-year-old male presented with urinary incontinence and diagnosed as Ewing's sarcoma after 6 weeks' delay. Clinicians should suspect from pelvic tumors in the presence of urinary incontinence especially associated with low back pain. [Cukurova Med J 2015; 40(Suppl 1: 94-96

    There has been considerable interest in identifying and addressing the specific needs of early-episode patients diagnosed with schizophrenia in the hope that by addressing such needs early, chronic disabilities can be avoided. One hundred twenty-eight early-episode and 571 chronic patients were compared on socio-demographic characteristics, clinical symptoms and history of childhood trauma. Symptoms were measured with the Positive and Negative Syndrome Scale (PANSS), and trauma with the short version of the Childhood Trauma Questionnaire. First-episode patients scored 9.3% higher than chronic patients on the PANSS positive symptom scale and 16.3% lower on the negative symptom scale. More first episode patients reported childhood sexual abuse (P = 0.033); however, fewer reported childhood emotional neglect (P = 0.01). Childhood trauma was associated with positive symptoms, specifically with hallucinations in first-episode patients (r = 0.174; P = 0.049). Moreover, fewer parents of first episode patients were living alone (P = 0.008). On multiple logistic regression, the first-episode patients were younger (odds ratio = 0.92), had higher PANSS positive symptom scores (odds ratio 1.04) and lower negative symptom scores (odds ratio 0.948 recalculate). More positive symptoms, fewer negative symptoms, less isolated parents and greater risk of childhood sexual abuse might warrant attention in first episode schizophrenia and perhaps should be a focus for the development of targeted interventions. © 2012 Wiley Publishing Asia Pty Ltd.

    Full Text Available Primary Renal Sarcoma is rare tumor comprising only 1% of all renal tumours. Synovial sarcomas are generally deep-seated tumors arising in the proximity of large joints of adolescents and young adults and account for 5-10% of all soft tissue tumours. Primary synovial sarcoma of kidney is rare and has poor prognosis. It can only be diagnosed by immunohistochemistry. It should be considered as a differential in sarcomatoid and spindle cell tumours. We present a case of 33-year-old female, who underwent left sided radical nephrectomy for renal tumour. Histopathology and genetic analysis diagnosed it to be primary renal synovial sarcoma. Patient underwent radiation therapy and 2 years follow up is uneventful. A brief case report with review of literature is presented.

    Full Text Available Ewing's sarcoma is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. Clinical presentation is usually dominated by local bone pain and a mass. Magnetic resonance best defines the extent of the lesion. Patients diagnosed with Ewing's sarcoma within  last years show a improving  survival rate . Rehabilitation seems to be a crucial part of multimodal therapy.

    Ewing sarcoma survivors (ESSs) are at increased risk for treatment-related complications. The incidence of treatment-related morbidity and late mortality with aging is unknown. This study reports survival probabilities, estimated with the Kaplan-Meier method, and the cumulative incidence of cause-specific mortality and chronic conditions among ESSs in the Childhood Cancer Survivor Study who were treated between 1970 and 1986. Piecewise exponential models were used to estimate relative rates (RRs) and 95% confidence intervals (CIs) for these outcomes. Chronic conditions were graded with the Common Terminology Criteria for Adverse Events (version 4.03). Among 404 5-year ESSs (median age at last follow-up, 34.8 years; range, 9.1-54.8 years), the 35-year survival rate was 70% (95% CI, 66%-74%). Late recurrence (cumulative incidence at 35 years, 15.1%) was the most common cause of death, and it was followed by treatment-related causes (11.2%). There were 53 patients with subsequent neoplasms (SNs; cumulative incidence at 35 years, 24.0%), and 38 were malignant (14.3% at 35 years). The standardized incidence ratios were 377.1 (95% CI, 172.1-715.9) for osteosarcoma, 28.9 (95% CI, 3.2-104.2) for acute myeloid leukemia, 14.9 (95% CI, 7.9-25.5) for breast cancer, and 13.1 (95% CI, 4.8-28.5) for thyroid cancer. Rates of chronic conditions were highest for musculoskeletal (RR, 18.1; 95% CI, 12.8-25.7) and cardiac complications (RR, 1.8; 95% CI, 1.4-2.3). Thirty-five years after the diagnosis, the cumulative incidences of any chronic conditions and 2 or more chronic conditions were 84.6% (95% CI, 80.4%-88.8%) and 73.8% (95% CI, 67.8%-79.9%), respectively. With extended follow-up, ESSs' risk for late mortality and SNs does not plateau. Treatment-related chronic conditions develop years after therapy, and this supports the need for lifelong follow-up.

    Full Text Available OBJECTIVE: To model the potential interaction between previously identified biomarkers in children sarcomas using artificial neural network inference (ANNI. METHOD: To concisely demonstrate the biological interactions between correlated genes in an interaction network map, only 2 types of sarcomas in the children small round blue cell tumors (SRBCTs dataset are discussed in this paper. A backpropagation neural network was used to model the potential interaction between genes. The prediction weights and signal directions were used to model the strengths of the interaction signals and the direction of the interaction link between genes. The ANN model was validated using Monte Carlo cross-validation to minimize the risk of over-fitting and to optimize generalization ability of the model. RESULTS: Strong connection links on certain genes (TNNT1 and FNDC5 in rhabdomyosarcoma (RMS; FCGRT and OLFM1 in Ewing's sarcoma (EWS suggested their potency as central hubs in the interconnection of genes with different functionalities. The results showed that the RMS patients in this dataset are likely to be congenital and at low risk of cardiomyopathy development. The EWS patients are likely to be complicated by EWS-FLI fusion and deficiency in various signaling pathways, including Wnt, Fas/Rho and intracellular oxygen. CONCLUSIONS: The ANN network inference approach and the examination of identified genes in the published literature within the context of the disease highlights the substantial influence of certain genes in sarcomas.

    Bone sarcomas are malignancies with peak incidence in adolescents and young adults. The most frequent are osteosarcoma and Ewing sarcoma/PNET, in an older adults are seen chondrosarcomas, other ones are rare. In general, biology of sarcomas is closely related to pediatric malignancies with fast growth, local aggressiveness, tendency to early hematogenic dissemination and chemo sensitivity. Diagnostics and treatment of bone sarcomas should be done in well experienced centres due to low incidence and broad issue of this topic. An interdisciplinary approach and staff education is essential in due care of patients with bone sarcoma. If these criteria are achieved, the cure rate is contemporary at 65 - 70 %, while some subpopulation of patients has chance for cure up to 90 %. Osteosarcoma and Ewing sarcoma/PNET are discussed below as types of most frequent bone sarcoma. (author)

    Full Text Available Abstract Sarcomas were one of the first solid cancers to be linked to ionizing radiation exposure. We reviewed the current evidence on this relationship, focusing particularly on the studies that had individual estimates of radiation doses. There is clear evidence of an increased risk of both bone and soft tissue sarcomas after high-dose fractionated radiation exposure (10 + Gy in childhood, and the risk increases approximately linearly in dose, at least up to 40 Gy. There are few studies available of sarcoma after radiotherapy in adulthood for cancer, but data from cancer registries and studies of treatment for benign conditions confirm that the risk of sarcoma is also increased in this age-group after fractionated high-dose exposure. New findings from the long-term follow-up of the Japanese atomic bomb survivors suggest, for the first time, that sarcomas can be induced by acute lower-doses of radiation (

    Malignant neoplasias in childhood generally are an increased risk for the patient to fall ill with a second tumor. Second tumors in former irradiation field are seldom, but are acknowledged radiogenically if histology is different to that of the first tumor and a sufficiently long period is between the two tumors. A patient is presented who had been operated and irradiated because of an adenosarcoma of the kidney at the age of seven and who has fallen ill with a neurogenic sarcoma in the irradiation area more than 30 years later. The same patient had to suffer from radiogenic retardation during differentiation of the lumbar apparatus of attitude and locomotion and on the other hand be became father of a healthy daughter at the age of 32.

    Full Text Available Abstract Background A high frequency of childhood abuse has often been reported in adult psychiatric patients. The present survey explores the relationship between psychiatric diagnoses and positive and negative life events during childhood and adulthood in psychiatric samples. Methods A total of 192 patients with diagnoses of alcohol-related disorders (n = 45, schizophrenic disorders (n = 52, affective disorders (n = 54, and personality disorders (n = 41 completed a 42-item self-rating scale (Traumatic Antecedents Questionnaire, TAQ. The TAQ assesses personal positive experiences (competence and safety and negative experiences (neglect, separation, secrets, emotional, physical and sexual abuse, trauma witnessing, other traumas, and alcohol and drugs abuse during four developmental periods, beginning from early childhood to adulthood. Patients were recruited from four Psychiatric hospitals in Germany, Switzerland, and Romania; 63 subjects without any history of mental illness served as controls. Results The amount of positive experiences did not differ significantly among groups, except for safety scores that were lower in patients with personality disorders as compared to the other groups. On the other side, negative experiences appeared more frequently in patients than in controls. Emotional neglect and abuse were reported in patients more frequently than physical and sexual abuse, with negative experiences encountered more often in late childhood and adolescence than in early childhood. The patients with alcohol-related and personality disorders reported more negative events than the ones with schizophrenic and affective disorders. Conclusions The present findings add evidence to the relationship between retrospectively reported childhood experiences and psychiatric diagnoses, and emphasize the fact that a emotional neglect and abuse are the most prominent negative experiences, b adolescence is a more 'sensitive' period for negative

    Moriz Kaposi was the first who, in 1872, described five patients presenting with 'sarcoma idiopathicum multiple hemorrhagicum'. In 1912 Sternberg termed this disease Kaposi's sarcoma. Since then various forms of this rare disease have been observed. In 1914 Hallenberg described the first cases of African or endemic Kaposi's sarcoma. In the 1960's the first reports discussing Kaposi's sarcoma following organ transplantation and immunosuppressive therapy were published. After 1981, the epidemic form associated with the acquired immunodeficiency syndrome (AIDS) was described. All these forms, their history, treatment methods and the role of radiation therapy in the management of this rare malignancy are discussed, and the literature is reviewed. (authors)

    A 16-year-old male was diagnosed with Ewing sarcoma of the ribcage with pulmonary metastases. Six months after completion of scheduled therapy, he was found to have a new intracardiac mass, presumed recurrent Ewing sarcoma. EWSR1 fusion was not detected by droplet digital polymerase chain reaction from blood plasma. After no improvement with salvage chemotherapy, he underwent surgical resection that identified a low-grade spindle cell sarcoma. Despite the near-synchronous presentation of 2 unrelated sarcomas, extensive genomic analyses did not reveal any unifying somatic or germline mutations nor any apparent cancer predisposition. This case also highlights the potential role of utilizing plasma cell-free DNA for diagnosing tumors in locations where biopsy confers high morbidity.

    Full Text Available Objectives: To examine whether there is an association between neighbourhood deprivation and diagnosed childhood obesity, after accounting for family- and individual-level socio-demographic characteristics. Methods: An open cohort of all children aged 0-14 years was followed between January 1, 2000 and December 31, 2010. Childhood residential locations were geocoded and classified according to neighbourhood deprivation. Data were analysed by multilevel logistic regression, with family- and individual-level characteristics at the first level and level of neighbourhood deprivation at the second level. Results: During the study period, among a total of 948,062 children, 10,799 were diagnosed with childhood obesity. Age-adjusted cumulative incidence for diagnosed childhood obesity increased with increasing level of neighbourhood deprivation. Incidence of diagnosed childhood obesity increased with increasing neighbourhood-level deprivation across all family and individual-level socio-demographic categories. The odds ratio (OR for diagnosed childhood obesity for those living in high-deprivation neighbourhoods versus those living in low-deprivation neighbourhoods was 2.44 (95% confidence interval (CI = 2.22-2.68. High neighbourhood deprivation remained significantly associated with higher odds of diagnosed childhood obesity after adjustment for family- and individual-level socio-demographic characteristics (OR = 1.70, 95% CI = 1.55-1.89. Age, middle level family income, maternal marital status, low level education, living in large cities, advanced paternal and maternal age, family history of obesity, parental history of diabetes, chronic obstructive pulmonary disease, alcoholism and personal history of diabetes were all associated with higher odds of diagnosed childhood obesity. Conclusions: Our results suggest that neighbourhood characteristics affect the odds of diagnosed childhood obesity independently of family- and individual-level socio

    Full Text Available Pneumonia is the leading infectious cause of death in children worldwide. Each year, pneumonia kills an estimated 935,000 children under five years of age, with most of these deaths occurring in developing countries. The current approach for pneumonia diagnosis in low-resource settings--using the World Health Organization Integrated Management of Childhood Illness (IMCI paper-based protocols and relying on a health care provider's ability to manually count respiratory rate--has proven inadequate. Furthermore, hypoxemia--a diagnostic indicator of the presence and severity of pneumonia often associated with an increased risk of death--is not assessed because pulse oximetry is frequently not available in low-resource settings. In an effort to address childhood pneumonia mortality and improve frontline health care providers' ability to diagnose, classify, and manage pneumonia and other childhood illnesses, PATH collaborated with the University of Washington to develop "mPneumonia," an innovative mobile health application using an Android tablet. mPneumonia integrates a digital version of the IMCI algorithm with a software-based breath counter and a pediatric pulse oximeter. We conducted a design-stage usability field test of mPneumonia in Ghana, with the goal of creating a user-friendly diagnostic and management tool for childhood pneumonia and other childhood illnesses that would improve diagnostic accuracy and facilitate adherence by health care providers to established guidelines in low-resource settings. The results of the field test provided valuable information for understanding the usability and acceptability of mPneumonia among health care providers, and identifying approaches to iterate and improve. This critical feedback helped ascertain the common failure modes related to the user interface design, navigation, and accessibility of mPneumonia and the modifications required to improve user experience and create a tool aimed at decreasing

    Anapalsia is rare in childhood rhabdomyosarcoma and has not been included in the International Classification of Rhabdomyosarcoma (ICR). A recent review of cases from the Soft Tissue Sarcoma Committee of the Children's Oncology Group (COG) suggests that anaplasia might be more common than previously reported and may impact clinical outcome. The prevalence of anaplasia (focal or diffuse) was prospectively assessed in 546 eligible cases who were registered in an Intergroup Rhabdomyosarcoma Study Group (IRSG) or COG therapeutic trial from 1995 through 1998. The incidence of anaplasia in tumor samples and its impact in predicting clinical outcome was assessed. Overall, 71 (13%) of all samples analyzed had anaplasia. Anaplasia was more common in patients with tumors in favorable sites and was less commonly observed in younger patients and in those with stage II, III, or clinical group III disease. Regardless of its distribution (focal or diffuse), on univariate analysis the presence of anaplasia negatively influenced the failure-free survival rate (63% vs 77% at 5 years) and overall survival (68% vs 82% at 5 years) rates in patients with embryonal rhabdomyosarcoma. This effect was most pronounced in children with intermediate-risk tumors. Anaplasia did not affect outcome in patients with alveolar tumors. The incidence of anaplasia in patients with rhabdomyosarcoma is higher than previously described and may be of prognostic significance in children with intermediate-risk embryonal rhabdomyosarcoma.

    The clinical picture of ulcerated purple plaques on the legs often suggests several diagnoses: Kaposi's sarcoma, stasis dermatitis, atrophie blanche (livedoid vasculitis), and a poorly understood condition called acroangiodermatitis of Favre-Chaix (pseudo-Kaposi's sarcoma). Even the skin biopsy may not always be conclusive. We describe our experience with three patients with pseudo-Kaposi's sarcoma, one with true Kaposi's sarcoma and two with atrophie blanche. Clinical and histopathologic similarities among these three conditions pointed up the need for additional confirmatory studies, i.e., isotope scanning. The technetium scan was positive in both Kaposi's sarcoma and pseudo-Kaposi's sarcoma but negative in atrophie blanche

    Objective:It has been suggested that high levels of prenatal testosterone exposure are implied in the etiology of male preponderance disorders such as autism spectrum disorder and ADHD. Within this scope, we studied the sex ratio (proportion of males) in siblings of individuals diagnosed with ADHD...... in childhood and adolescence. Method: We did a nationwide, register-based cohort study of the sex ratio in siblings of the 16,381 patients in Denmark diagnosed with ADHD at age 17 years and younger and registered in the nationwide Danish Psychiatric Central Register between January 1, 1994 and May 28, 2013....... Results: Among the 33,151 siblings, 17,041 were males and 16,110 females. This yields a sex ratio of 0.514, which is not statistically significant different from the Danish live birth sex ratio of 0.513 during the relevant years (p = .70). Conclusion: These findings provide no support for the hypothesis...

    This pilot study explored the volubility, consonant singleton acquisition, and syllable structure development between infants and toddlers (birth-24 months) with typical speech sound production (TYP) and those later diagnosed with childhood apraxia of speech (CAS). A retrospective longitudinal between- and within-subjects research design was utilized (TYP N=2; CAS N=4). Vocalizations from participants were analyzed between birth-24 months from home videotapes, volunteered by the children's parents, according to type (nonresonant vs. resonant), volubility, place and manner of consonant singletons, and syllable shape (V, CV, VC, CVC, VCV, CVCV, VCVC, and "Other"). Volubility between groups was not significant but statistically significant differences were found in the number of: resonant and non-resonant productions; different consonant singletons; different place features; different manner classes; and proportional use of fricative, glottal, and voiceless phones. Infants and toddlers in the CAS group also demonstrated difficulty with CVCs, had limited syllable shapes, and possible regression of vowel syllable structure. Data corroborate parent reports that infants and toddlers later diagnosed with CAS present differently than do those with typical speech sound skills. Additional study with infants and toddlers later diagnosed with non-CAS speech sound disorder is needed. Readers will: (1) describe current perspectives on volubility of infants and toddlers later diagnosed with CAS; (2) describe current perspectives of the consonant singleton and syllable shape inventories of infants and toddlers later diagnosed with CAS; and (3) discuss the potential differences between the speech sound development of infants and toddlers later diagnosed with CAS and those with typical speech sound skill.

    We examined decision-making in young adulthood in a follow-up study of females diagnosed with attention-deficit/hyperactivity disorder (ADHD) between 6 and 12 years. Participants with childhood ADHD (n = 114) and matched comparison females (n = 77), followed prospectively for 10 years, performed the Iowa Gambling Task (IGT) at ages 17-25 years. This task assesses preference for high-reward/high-risk chances that result in lower overall gains (disadvantageous decks of cards) compared to low-reward/low-risk chances that result in higher overall gains (advantageous decks of cards). Relative to comparison participants, young adult females with a history of ADHD did not increase their preference for advantageous decks across time blocks, suggesting difficulties in learning to change behavior over the course of the IGT. Overall, childhood diagnoses of ADHD were associated with disadvantageous decision-making in young adulthood. These results extend findings on decision-making in males with ADHD by demonstrating comparable levels of impairment in an all-female sample.

    Ewing sarcoma accounts for 10-15% of all childhood malignant bone tumours and is second in prevalence to osteosarcoma. The skull bones are an unusual site of origin of primary Ewing sarcoma in children. Previous reports concentrate on the neurosurgical aspects and relatively good outcome compared to other bone tumours of the calvarium. Reported cases mainly describe the imaging characteristics on CT. To describe the MRI and CT features of primary cranial Ewing sarcoma. The neuroimaging of three cases of primary cranial Ewing sarcoma are reviewed. Our three cases show an extra-axial mass that is high attenuation on CT and low signal on T2-weighted MRI. Haemorrhagic components, dural extension and contrast enhancement are also characteristic features. CT attenuation and magnetic resonance signal characteristics reflect sheets of densely packed cells seen in Ewing sarcoma. (orig.)

    Important refinements have taken place in the diagnosis of soft tissue sarcoma with extensive use of immuno-histochemistry. New entities have been described, while malignant histiocytofibroma, the most diagnosed sarcoma type during the last two decades, has been dismembered. As for prognosis, the new UICC classification is effectively more discriminating in the definition of prognostic groups; but the usefullness of new biological or genetic markers remains to be assessed. Several breakthrough have taken place in the last years in the treatment of soft tissue sarcoma. Isolated limb perfusion with TNF, hyperthermia and melphalan have proven its efficacy, and is now an alternative to preoperative chemotherapy and/or radiotherapy for limb sparing treatment of the primary tumor site or to amputation. For systemic treatments, novel cytostatic drugs have been shown to be active in sarcomas, including ecteinascidine (ET743) and Glivec (STI571). This last drug has been shown to be remarkably active in c-kit+ stromal sarcoma of the gastro-intestinal tract. It can hopefully regarded as an example for targeted therapies, which may come with a better understanding of the molecular mechanisms triggered by the fundamental, specific genetic alterations shown in sarcoma.

    Granulocytic sarcoma is a variant presentation of acute myeloblastic leukemia, occurring in extramedullary locations. It is uncommon, but it may occur at any site and at any age, which necessitates its inclusion in the differential diagnosis of all undifferentiated tumors. Histology, touch-imprint cytology, cytochemistry, immunocytochemistry, electron microscopy, and molecular studies all contribute to the diagnosis.

    Ewing sarcoma is the second most frequent primary bone cancer affecting children or young adults. Advances in molecular biology have revealed common chromosomal translocations such as EWS-FLI1 among Ewing sarcoma and related diseases such as primitive neuroectodermal tumor (PNET), so these are considered as Ewing sarcoma family tumor (ESFT). Although fewer than 10% of patients with ESFT survived before establishment of modern multiagent chemotherapy, the multimodal therapeutic regimens including combination chemotherapy, radiotherapy, and surgery can cure 60% of patients with localized disease, due to the collaborative research in European-American or the international trials. The standard chemotherapy for localized ESFT now comprises vincristine, actinomycin D, cyclophosphamide and doxorubicin (VACD) in Europe or vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide (VDC-IE) in North America. Meanwhile, those with metastatic disease have a much worse outcome with an approximately 10-30% 5-year event-free survival rate. New American-European collaborative trials such as EURO-E.W.I.N.G. 99 are in progress for further improvement of the cure rate in localized and metastatic ESFT. In Japan, Japan Ewing Sarcoma Study Group (JESS) phase II clinical trial for localized ESFT, and some clinical trials including new drugs are ongoing and waiting for results. (author)

    Anthracycline cardiotoxicity is an important side-effect in long-term childhood cancer survivors. We evaluated the incidence of and factors associated with anthracycline cardiotoxicity in a population of patients diagnosed with bone or soft tissue sarcoma. Materials and methods We retrospectively enrolled patients diagnosed with bone or soft tissue sarcoma, from 1995 to 2011, treated with anthracycline chemotherapy at our Centre and with a follow-up echocardiography carried out ⩾3 years from cardiotoxic therapy completion. Cardiac toxicity was graded using Common Terminology Criteria for Adverse Events version 4.0. A total of 82 patients were eligible. The median age at treatment was 11.9 years (1.44-18). We evaluated the median cumulative anthracycline dose, age at treatment, sex, thoracic radiotherapy, hematopoietic stem cell transplantation, and high-dose cyclophosphamide treatment as possible risk factors for cardiotoxicity. The median cumulative anthracycline dose was 390.75 mg/m2 (80-580). Of the 82 patients, 12 (14.6%) developed cardiotoxicity with grade ⩾2 ejection fraction decline: four patients were asymptomatic and did not receive any treatment; six patients were treated with pharmacological heart failure therapy; one patient with severe cardiomyopathy underwent heart transplantation and did not need any further treatment; and one patient died while waiting for heart transplantation. The median time at cardiac toxicity, from the end of anthracycline frontline chemotherapy, was 4.2 years (0.05-9.6). Cumulative anthracycline dose ⩾300 mg/m2 (p 0.04) was the only risk factor for cardiotoxicity on statistical analyses. In our population, the cumulative incidence of cardiotoxicity is comparable to rates in the literature. This underlines the need for primary prevention and lifelong cardiac toxicity surveillance programmes in long-term childhood cancer survivors.

    Much of our knowledge regarding cancer immunotherapy has been derived from sarcoma models. However, translation of preclinical findings to bedside success has been limited in this disease, though several intriguing clinical studies hint at the potential efficacy of this treatment modality. The rarity and heterogeneity of tumors of mesenchymal origin continues to be a challenge from a therapeutic standpoint. Nonetheless, sarcomas remain attractive targets for immunotherapy, as they can be characterized by specific epitopes, either from their mesenchymal origins or specific alterations in gene products. To date, standard vaccine trials have proven disappointing, likely due to mechanisms by which tumors equilibrate with and ultimately escape immune surveillance. More sophisticated approaches will likely require multimodal techniques, both by enhancing immunity, but also geared towards overcoming innate mechanisms of immunosuppression that favor tumorigenesis

    The 5-year survival rate for childhood cancer has increased to 80%, resulting in a growing population of adult survivors of childhood cancer (ASOCC). Long-term endocrine dysfunction is as high as 63% when screened in research protocols. The purpose of this study was to evaluate the prevalence of endocrine testing, endocrine dysfunction, diabetes, obesity, and endocrinologist visits outside of a research screening protocol. A retrospective chart review was performed for 176 ASOCC who were diagnosed with cancer before age 18, followed at least 10 years, were now at least 18, and had survived to the time of chart review. After a mean follow-up of 15.2 years (range 10-21 years), 33.5% of ASOCC had endocrine dysfunction, excluding obesity and diabetes. These outcomes were more common in those with any radiation (64.8%, Pobese. Glycated hemoglobin A1C (A1C) testing was rare, but when performed, 38.1% were abnormal. 71% of subjects had never seen an endocrinologist. Even among subjects with cranial radiation, 65.4% had either never seen an endocrinologist or had not seen one in the past 5 years. This cohort of ASOCC showed high rates of endocrine dysfunction, overweight or obesity, and diabetes in those who had been tested, combined with low rates of testing and endocrinology evaluation. Endocrinologists need to be aware of the endocrine risks in ASOCC, the need for long-term monitoring, and increase their collaboration with oncology.

    Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal...... sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referrals and diagnostic investigations were collected from clinical files from primary health care, local hospitals, and from the sarcoma centre. Lead times were divided into patient delays and health care...... at the general practitioner, 36 days at local hospitals, and 55 days at the sarcoma centre. Conclusion. Centralization per se is not sufficient for optimized and efficient management.

    Autism is a neurodevelopmental disorder with multifactorial etiology and varied presentation, in which early diagnosis is crucial to the implementation of early treatment. A 6-year-old child clinically diagnosed with autism, and a normal magnetic resonance imaging underwent dedicated 18F-fluorodeoxyglucose brain positron emission tomography (PET) as an ancillary investigation. PET image showed diffuse bilateral temporal hypometabolism. Although PET imaging is currently not indicated in the evaluation of autism, characteristic imaging patterns on PET can provide corroborative information and increase the diagnostic confidence for the same

    Full Text Available Objectives: Given the paucity of research on adolescent ADHD, this study aimed to establish the prevalence of DSM-IV ADHD in a cohort of South African adolescents who had been diagnosed with the disorder in childhood. It also aimed to establish the prevalence of psychiatric comorbidities and adjustment difficulties in this sample. Method: Data regarding age of diagnosis, current ADHD status, current ADHD-related pharmacological management, current psychopathology and current adjustment were gathered from 64 adolescents and their guardians via self-report questionnaire. Descriptive statistics were calculated with regard to current ADHD status, comorbid psychopathology and adjustment difficulties, as well as current ADHD-related medication. Results: According to parent reports, 59.38% of the sample met DSM-IV criteria for ADHD Inattentive subtype, while 37.50% met the criteria for ADHD Hyperactive/Impulsive subtype. Approximately sixty-four percent (64.06% of the adolescents were still using stimulant medication. Based on the adolescent self-report, 43.75% of the sample reported clinically significant symptoms of psychopathology or maladjustment. Furthermore, 39.28% of the adolescents met the diagnostic criteria for at least one psychiatric comorbidity. Conclusion: ADHD did persist into adolescence in the current sample. A significant psychopathological and maladjustment load appears evident amongst adolescents previously diagnosed with ADHD despite continuous pharmacological management of the condition.

  2. How do childhood diagnoses of type 1 diabetes cluster in time?

    Directory of Open Access Journals (Sweden)

    Colin R Muirhead

    Full Text Available BACKGROUND: Previous studies have indicated that type 1 diabetes may have an infectious origin. The presence of temporal clustering-an irregular temporal distribution of cases--would provide additional evidence that occurrence may be linked with an agent that displays epidemicity. We tested for the presence and form of temporal clustering using population- based data from northeast England. MATERIALS AND METHODS: The study analysed data on children aged 0-14 years diagnosed with type 1 diabetes during the period 1990-2007 and resident in a defined geographical region of northeast England (Northumberland, Newcastle upon Tyne, and North Tyneside. Tests for temporal clustering by time of diagnosis were applied using a modified version of the Potthoff-Whittinghill method. RESULTS: The study analysed 468 cases of children diagnosed with type 1 diabetes. There was highly statistically significant evidence of temporal clustering over periods of a few months and over longer time intervals (p<0.001. The clustering within years did not show a consistent seasonal pattern. CONCLUSIONS: The study adds to the growing body of literature that supports the involvement of infectious agents in the aetiology of type 1 diabetes in children. Specifically it suggests that the precipitating agent or agents involved might be an infection that occurs in "mini-epidemics".

    2003-01-01

    This study explores the contribution of cognitive processes to comprehension skills in adults who suffered from childhood developmental dyslexia (CD). The performance of adults with CD (ages 17 to 23), chronological age-matched (CA) adults, and reading level-matched (RL) children was compared on measures of phonological processing, naming speed, working memory (WM), general knowledge, vocabulary, and comprehension. The results showed that adults with CD scored lower on measures of phonological processing, naming speed, WM, general knowledge, and vocabulary when compared to CA readers but were comparable to RL children on the majority of process measures. Phonological processing, naming speed, vocabulary, general knowledge, and listening comprehension contributed independent variance to reading comprehension accuracy, whereas WM, intelligence, phonological processing, and listening comprehension contributed independent variance to comprehension fluency. Adults with CD scored lower than CA adults and higher than RL children on measures of lexical processing, WM, and listening comprehension when word recognition and intelligence were partialed from the analysis. In summary, constraints in phonological processing and naming speed mediate only some of the influence of high-order processes on reading comprehension. Furthermore, adults with CD experience difficulties in WM, listening comprehension, and vocabulary independently of their word recognition problems and intellectual ability.

    Phenylketonuria is one of the most prevalent autosomal recessive hereditary disorders in Turkey. If untreated, it results in severe brain damage and can also be associated with autism in certain patients. We present a three-year old boy who exhibited the symptoms of autism and was subsequently diagnosed with phenylketonuria. This case illustrates that because the majority of autism cases are idiopathic, an occasional patient with a metabolic disorder might be overlooked especially in the era of newborn screening. We also discuss the possible pathogenetic processes leading to autistic symptoms in phenylketonuria, and wish to draw attention to the possibility of cases missed in the screening program because of less than 100% coverage or insufficient food intake before blood sampling. Clinicians should keep in mind the possibility of treatable disorders in children with autism even when such disorders appear unlikely.

    Eczema is common among children, and in the UK the majority are managed by GPs. The most common cause of poor disease control is incorrect use of topical treatments. There is a lack of research into the challenges faced by GPs in diagnosing and managing this condition. To explore the experiences of GPs in assessing and managing children with eczema. Qualitative study in primary care in England. Semi-structured interviews with 15 GPs were audiorecorded, transcribed verbatim, and analysed thematically using the framework method. GPs described a paucity of dermatology training. Although most GPs were confident diagnosing uncomplicated eczema, they reported using a trial-and-error approach to prescribing emollients, and were uncertain about quantities of topical treatments to issue. Mild and moderate potency topical corticosteroids (TCS) were commonly used, but most GPs lacked confidence in recommending potent TCS, and viewed parents or carers to be fearful of using all strengths of TCS. GPs perceived adherence to treatments to be low, but provision of information to support self-care was variable. Routine review of medication use or disease control was uncommon, which GPs attributed to service constraints. Participants' views on the causes and management of eczema were perceived to be at odds with parents and carers, who were said to be overly focused on an underlying cause, such as allergy. GP uncertainty in managing eczema, lack of routine information and review, and perceived dissonance with parents around causation and management may be contributing to low concordance with treatments. © British Journal of General Practice 2018.

    Common environmental etiological factors between borderline personality disorder (BPD) and attention deficit/hyperactivity disorder (ADHD) have not been fully studied. The main aim of this study was to investigate the relationship between childhood trauma histories, assessed by the Childhood Trauma Questionnaire-Short Form (CTQ-SF), with adult BPD, ADHD or BPD-ADHD diagnoses. Comorbid BPD-ADHD patients exhibited significantly higher clinical severity and higher scores in the Total Neglect Scale, compared to BPD and ADHD patients, and only a marginal difference was observed for Sexual Abuse when BPD and ADHD patients were compared. Physical Trauma Scales were associated with ADHD diagnosis, whereas Emotional Abuse and Sexual Abuse Scales were associated with BPD or BPD-ADHD diagnoses. The study findings support the association between experiencing traumatic events in childhood and a higher clinical severity of BPD in adulthood. Furthermore, physical trauma history in childhood could be associated with the persistence of ADHD in adulthood and emotional or sexual abuse with later development of BPD or comorbid BPD-ADHD. Whereas experiencing childhood traumas is associated with later development of more general psychopathology, our study supports that a specific type of traumatic event could increase the risk for the consolidation of a concrete psychiatric disorder in the trajectory from childhood to adulthood of vulnerable subjects.

    Pneumonia is the third leading cause of death in children under 5 years of age worldwide. In pediatrics, both the accuracy and safety of diagnostic tools are important. Lung ultrasound (LUS) could be a safe diagnostic tool for this reason. We searched in the literature for diagnostic studies about LUS to predict pneumonia in pediatric patients using systematic review and meta-analysis. The Medline, CINAHL, Cochrane Library, Embase, SPORTDiscus, ScienceDirect, and Web of Science databases from inception to September 2017 were searched. All studies that evaluated the diagnostic accuracy of LUS in determining the presence of pneumonia in patients under 18 years of age were included. 1042 articles were found by systematic search. 76 articles were assessed for eligibility. Seventeen studies were included in the systematic review. We included 2612 pooled cases. The age of the pooled sample population ranged from 0 to about 21 years old. Summary sensitivity, specificity, and AUC were 0.94 (IQR: 0.89-0.97), 0.93 (IQR: 0.86-0.98), and 0.98 (IQR: 0.94-0.99), respectively. No agreement on reference standard was detected: nine studies used chest X-rays, while four studies considered the clinical diagnosis. Only one study used computed tomography. LUS seems to be a promise tool for diagnosing pneumonia in children. However, the high heterogeneity found across the individual studies, and the absence of a reliable reference standard, make the finding questionable. More methodologically rigorous studies are needed.

    Purpose: To evaluate the role of surgery in the treatment of Post-radiation sarcomas Materials. Post-radiation sarcomas is a rare entity and large series have rarely been reported. In order to improve knowledge about this entity the Radiotherapist group of the French Cancer Centres (FNCLCC) decided to collect retrospectively the cases treated in their institutions. In order to be sure of the histology, all the cases were reviewed by a panel of pathologists of the FNCLCC Pathologist group. A total of 129 cases of sarcomas, and 108 were reviewed; analysis of 8 is in progress, and no material was obtained in the other 11 cases. The diagnosis of sarcomas was confirmed in 80 cases. All patients (60 F, 20 M) have received radiation therapy (median dose 50 Gy; 9-110 Gy) for the treatment of the primary tumor. At this time the age was 44 years (6-83 y). Diagnoses included: breast C. 42%, Lymphomas 11.5%, gynaecological C. 10% benign lesions 5% miscellaneous. Sarcomas developed after a mean interval of 12 years (3-64 y), in bone in 30% of the cases and in soft tissue in 70%. The majority of lesions (90%) developed in the irradiated field (dose received was between 50 Gy and 60 Gy). Histologically there were 29% Malignant HistiocytofibroSarcomas, 19% OsteoSarcomas, 15% FibroSarcomas, 9% LipoSarcomas, 6% LeiomyoSarcomas, miscellaneous sarcomas 22%. Treatment included: Surgery 28 cases, Surgery+Chemotherapy 17 cases, Chemotherapy only 16 cases, Radiation therapy only 1 case, surgery + Radiation therapy 5 cases, Radiation therapy +chemotherapy 6 cases, Surgery + Radiation therapy + Chemotherapy 7 cases, no treatment 5 cases. Results. The outcome is known for all but 3 patients. 51 patients have died (44 of their sarcoma, 4 of the primary tumour, 2 of other cause and 1 iatrogenic). Median survival is 23 months (95% confidence interval 16-29 mo) but 9 patients survived 5 yr or more. Median survival was 43 mo for patients treated by surgery (28p), 6 mo for chemotherapy group (16 p

    Imaging and histology are two complementary morphological techniques which play a fundamental role in the diagnosis and management of soft tissue sarcomas. Imaging allows to identify some pseudosarcomatous benign lesions such as myositis ossificans, intramuscular hemangioma, angiomyolipoma, intramuscular lipoma, giant cell tumour of tendon sheath, desmoid tumour and elastofibroma. There is no formal criterion for diagnosing a sarcoma on magnetic resonance imaging (MRI) but malignancy is strongly suspected with the presence of necrosis and vascular, bone or joint invasion. Imaging may also suggest some histological types of sarcoma such as well-differentiated liposarcoma, dedifferentiated liposarcoma, synovial sarcoma or extraskeletal osteosarcoma. Imaging is also extremely helpful in determining the appropriate kind of sampling to carry out and in guiding the performance of a microbiopsy. The appearance observed on imaging should always be taken into consideration for the interpretation of the microbiopsy by the pathologist.

    Full Text Available Ewing's sarcoma or Ewing tumor is a rare primary bone tumor that affects mainly children and adolescents. It belongs to a group of cancers known collectively as Ewing sarcoma family tumors or Ewing family tumors. By the time, the patients present and diagnosis is made, the disease is usually advanced. We reviewed the case files of two patients managed in our hospital within one (2013. Fine-needle aspirations for cytology (FNAC and tissue biopsy were used for diagnosis in the two patients we had. The two patients, both males aged 20 years and 38 years presented late and FNAC and tissue biopsy revealed Ewing's sarcoma. They were referred for radio- and chemotherapy. However, due to poor socioeconomic status, they died of their primary disease. Unless diagnosed early, and in the absence of a multidisciplinary approach, Ewing's sarcoma is a fatal disease.

    Background -Late survival and symptomatic status of children with hypertrophic cardiomyopathy (HCM) have not been well defined. We examined long-term outcomes for pediatric HCM. Methods -The National Australian Childhood Cardiomyopathy Study is a longitudinal population-based cohort study of children (0-10 years) diagnosed with cardiomyopathy between 1987 and 1996. The primary study end-point was time to death or cardiac transplantation. Results -There were 80 patients with HCM with median age at diagnosis of 0.48 (Inter-quartile range [IQR] 0.1, 2.5) years. Freedom from death/transplantation (95% confidence interval [CI]) was 86 (77-92)% one year after presentation, 80 (69-87)% at 10 years and 78 (67-86)% at 20 years. From multivariable analyses, risk factors for death/transplantation included symmetric left ventricular hypertrophy at the time of diagnosis (hazard ratio [HR] 4.20 95%CI 1.60, 11.05 p=0.004), Noonan syndrome (HR 2.88, 95%CI 1.02, 8.08, p=0.045), higher posterior wall thickness z-score (HR 1.45, 95%CI 1.22, 1.73, p<0.001) and lower fractional shortening z-score (HR 0.84, 95%CI 0.74, 0.95, p=0.005) during follow-up. Nineteen (23%) subjects underwent left ventricular myectomy. At median 15.7 years' follow-up, 27 (42%) of 63 survivors were treated with beta-blocker and 13 (21%) had an implantable cardioverter-defibrillator. Conclusions -The highest risk of death or transplantation for children with HCM is within one year post-diagnosis, with low attrition rates thereafter. Many subjects receive medical, surgical or device therapy.

    Full Text Available Ewing's sarcoma (ES is a rare tumor that is most common in children and young adults. Late effects of ES therapy include second cancers, a tragic outcome for survivors of such a young age. This paper will explore the frequencies and types of malignancies that occur after ES. Additionally, it will review how second malignancies have changed with the shift in treatment from high-dose radiation to chemotherapy regimens including alkylators and epipodophyllotoxins. The risk of additional cancers in ES survivors will also be compared to survivors of other childhood cancers. Finally, the possible genetic contribution to ES and second malignancies will be discussed.

    Primary lung neoplasms are rare in children. The most common primary lung malignancies in children are pleuropulmonary blastoma and carcinoid tumour. Synovial sarcoma (SS) accounts for approximately 1% of all childhood malignancies. In absolute terms, the SS of the lungs and pleura are extremely rare and pose a diagnostic difficulty. Soft tissue sarcomas usually have a high potential for metastases, however, metastasis to the brain is rare, even in widely disseminated disease, and it has been described only in 3 case reports previously. Primary pleuropulmonary SS with brain metastases is even rarer. Here we present a case of an 11-year-old boy who presented with respiratory complaints, viz. fever and cough for 20 days. Initial impression was lung abscess, however, on histopathological, immunohistochemical and molecular study, the disorder was diagnosed as synovial sarcoma. After a week from the first consult, the child developed neurological symptoms, viz., an episode of convulsion and gradually worsening power of the lower limb. Computed tomography scan and Magnetic Resonance Spectroscopy was suggestive of brain metastases. Given the rarity of primary lung neoplasms in children, clinical detection remains a challenge. Delayed diagnoses are common as respiratory symptoms may be attributed to inflammatory or infective processes. Primary pleuropulmonary synovial sarcoma is a rare tumour and it is not known to commonly metastasise to the brain. Though rare, primary pleuropulmonary SS should be considered an important differential among peadiatric primary lung neoplasms due to its potential for curability if detected early, and more aggressive metastatic pattern, e.g. brain metastases making early detection imperative.

    Ewing's sarcoma is a primary malignant tumor of bone occurring mostly in childhood. Few effective reconstruction techniques are available after wide resection of Ewing's sarcoma at the distal end of the tibia. Reconstruction after wide resection is especially difficult in children, as it is necessary to consider the growth and activity of the lower limbs. A 12-year-old Japanese boy had presented with right lower leg pain at age 8 years. Imaging examination showed a bone tumor accompanied by a large extra-skeletal mass in the distal part of his tibia. The tumor was histologically diagnosed as Ewing's sarcoma. The patient received chemotherapy, followed by wide resection. Reconstruction consisted of a bone transport method involving external fixation of Taylor Spatial Frame. To prevent infection after surgery, the external fixation pin was coated with iodine. One year after surgery, the patient showed poor consolidation of bone, so iliac bone transplantation was performed on the extended bones and docking site of the distal tibia. After 20 months, tibia formation was good. Three years after surgery, there was no evidence of tumor recurrence or metastases; bone fusion was good, and he was able to run. The bone transport method is an effective surgical method of reconstruction after wide resection of a bone tumor at the distal end of the tibia, if a pin can be inserted into the distal bone fragment. Coating external fixation pins with iodine may prevent postoperative infection.

    Williams, A.; Ezzell, G.; Zalupski, M.; Fontanesi, J.

    1996-01-01

    Purpose: To assess the efficacy and possible complications in patients diagnosed with Kaposi's sarcoma and treated with definitive brachytherapy. Methods and Materials: Between January, 1995 and December, 1995, four patients with Kaposi's sarcoma (KS) were treated with brachytherapy. Three patients, all with positive HIV status were treated using Iridium 192 (Ir-192) sources via a high-dose rate remote afterloader. One patient with endemic KS was treated using the application of catheters loaded with Californium 252. Eight sites were treated and included scalp, feet, nose, penis, hand, neck, and back. Dose rate for Ir-192 was 330cGy/fx to a total dose of 990cGy. The Californium was delivered as 100nGy/b.i.d. to a total dose of 900nGy. Follow-up as ranged from 2-6 months. Results: All four patients remain alive. Seven of eight sites have had complete clinical response and each patient has reported durable pain relief that has not subsided through last follow-up of 1/96. Two of eight sites, both treated with surface mold technique with Californium 252 developed moist desquamation. The remaining six sites did not demonstrate significant toxicity. Conclusion: Brachytherapy can offer Kaposi's sarcoma patients results that are equivalent to external beam radiation therapy, with minimal complications, a shorter treatment time and potential cost effectiveness

    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.

    The protracted and highly variable development of prefrontal cortex regions that support cognitive control has been purported to shape the adult outcome of attention-deficit/hyperactivity disorder (ADHD). This neurodevelopmental model was tested in a prospectively followed sample of 27 adult probands who were diagnosed with ADHD in childhood and 28 carefully matched comparison subjects aged 21-28 years. Probands were classified with persistent ADHD or remitted ADHD. Behavioral and neural responses to the Stimulus and Response Conflict Task (SRCT) performed during functional magnetic resonance imaging (fMRI) were compared in probands and comparison subjects and in probands with persistent and remitted ADHD. Response speed and accuracy for stimulus, response, and combined conflicts did not differ across groups. Orbitofrontal, inferior frontal and parietal activation was lower in probands than comparison subjects, but only for combined conflicts, when demand for cognitive control was highest. Reduced activation for combined conflicts in probands was almost wholly attributable to the persistence of ADHD; orbitofrontal, inferior frontal, anterior cingulate and parietal activation was lower in probands with persistent ADHD than both probands with remitted ADHD and comparison subjects, but did not differ between probands with remitted ADHD and comparison subjects. These data provide the first evidence that prefrontal and parietal activation during cognitive control parallels the adult outcome of ADHD diagnosed in childhood, with persistence of symptoms linked to reduced activation and symptom recovery associated with activation indistinguishable from adults with no history of ADHD.

    Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade), undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases.

    A total of 468 cases of bone, soft tissue and visceral sarcomas (and certain other tumours) diagnosed during the years 1982-84 in North West England were entered in a study of histopathological peer review, incidence and survival. This paper describes the effects of peer review. Material was reviewed by a panel of five pathologists for 413 of the 450 cases originally registered as sarcomas with the Regional Cancer Registry. The diagnosis of sarcomas was confirmed in 76% cases and and there was agreement on sub-type for 53% cases. Measures of agreement were lowest for the two sub-types most commonly diagnosed i.e. malignant fibrous histiocytoma and leiomyosarcoma. Degree of agreement between individual pathologists and final panel diagnosis was also very variable but never less than 65%. It is concluded that second opinion is essential in cases of presumed sarcomas for studies of incidence and aetiology and to ensure that appropriate treatment is selected.

    Improvements in survival for Ewing sarcoma pediatric and adolescent patients have been modest over the past 20 years. Combinations of anticancer agents endure as an option to overcome resistance to single treatments caused by compensatory pathways. Moreover, combinations are thought to lessen any...... associated adverse side effects through reduced dosing, which is particularly important in childhood tumors. Using a parallel phenotypic combinatorial screening approach of cells derived from three pediatric tumor types, we identified Ewing sarcoma-specific interactions of a diverse set of targeted agents...... including approved drugs.

More than half (53% of these originate from the striated muscles and are called rhabdomyosarcomas (RMS the remaining are nonrhabdomyosarcoma soft tissue sarcomas (NRSTS. Almost two-thirds of RMS cases are diagnosed in children < 6 years of age. They can arise at varied locations like the head and neck region, genitourinary tract, extremities, trunk and retroperitoneum. Pathologically RMS is now classified as superior, intermediate and poor outcome histologies. For stratification of treatment and also comparison of results the RMS are now staged both by the clinical grouping and the TNM staging systems. The ultimate outcome depends on the site, extent of disease and histology. Currently, approximately 70% of the patients survive for 5 years or more and are probably cured. This is credited to the use of multi-modal, risk-adapted therapy, refinements in tumor grouping and better supportive care which has emerged out of cooperative studies like Intergroup Rhabdomyosarcoma Study (IRS and the International Society of Pediatric Oncology studies (SIOP. The treatment involves chemotherapy, radiotherapy and organ/function preserving surgery. The gold standard chemotherapy is still vincristine, actinomycin D and cyclophosphamide (VAC regime with high doses of intensity bone marrow rescue with colony stimulating factors. The NRSTS are rare and of heterogenous histologies and so it has been difficult to arrive at a treatment strategy for these. What is definitely understood is that these are usually immature and poorly differentiated tumors that respond poorly to chemotherapy and so surgical resection forms the mainstay of treatment with adjuvant radiotherapy and chemotherapy to prevent local recurrences. In all likelihood, the molecular analysis of RMS will further refine current classification schemes and knowledge of genetic features of

    Full Text Available Neoplasms with epithelioid histology may be diagnostically challenging. Immunohisto chemistry (IHC can aid in confirming thedifferential diagnosis of mesotheliomas, melanomas, lymphomas, and soft tissue sarcomas, all tumors that can present with an epithelioid histology. Immunohistochemistry can also assist in confirming the type of sarcomas. Using cases diagnosed in acommunity hospital setting over a ten year period, the use of IHC in sarcomas will be illustrated.

    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.

    Pneumonia is the leading cause of infectious disease mortality in children. Currently, health care providers (HCPs) are trained to use World Health Organization Integrated Management of Childhood Illness (IMCI) paper-based protocols and manually assess respiratory rate to diagnose pneumonia in low-resource settings (LRS). However, this approach of relying on clinical signs alone has proven problematic. Hypoxemia, a diagnostic indicator of pneumonia severity associated with an increased risk of death, is not assessed because pulse oximetry is often not available in LRS. To improve HCPs' ability to diagnose, classify, and manage pneumonia and other childhood illnesses, "mPneumonia" was developed. mPneumonia is a mobile health application that integrates a digital version of the IMCI algorithm with a software-based breath counter and a pulse oximeter. A design-stage qualitative pilot study was conducted to assess feasibility, usability, and acceptability of mPneumonia in six health centers and five community-based health planning and services centers in Ghana. Nine health administrators, 30 HCPs, and 30 caregivers were interviewed. Transcribed interview audio recordings were coded and analyzed for common themes. Health administrators reported mPneumonia would be feasible to implement with approval and buy-in from national and regional decision makers. HCPs felt using the mPneumonia application would be feasible to integrate into their work with the potential to improve accurate patient care. They reported it was "easy to use" and provided confidence in diagnosis and treatment recommendations. HCPs and caregivers viewed the pulse oximeter and breath counter favorably. Challenges included electricity requirements for charging and the time needed to complete the application. Some caregivers saw mPneumonia as a sign of modernity, increasing their trust in the care received. Other caregivers were hesitant or confused about the new technology. Overall, this technology was

    Kaposi's sarcoma (KS) is the most common neoplasm in AIDS patients. The incidence of pulmonary involvement is approximately 20%. The radiological findings are reported in plain chest x-ray and computed tomography (CT) in 15 patients diagnosed as having pulmonary Kaposi's sarcoma, in whom concomitant pulmonary infection was ruled out. The most common radiological pattern was that of bilateral perihilar interstitial involvement (86%), while poorly defined multiple nodules seldom presented (13%). In 40% of cases, the pulmonary parenchymal lesion was accompanied by pleural effusion. This sign is useful in the differential diagnosis involving opportunistic P. carinii pneumonia, a very common process in these patients which rarely presents with pleural effusion. The chest CT finding that was most characteristic of pulmonary Kaposi's sarcoma was bilateral perihilar peribronchovascular enlargement. (Author)

    Ewing's sarcoma is a highly malignant neoplasm of the bone whose origin is still uncertain. A strong relationship exists between Ewing's sarcoma and tumors of neural origin (Ewing family of tumors). Ewing's sarcoma must be distinguished from other round-cell tumors like lymphoma and neuroblastoma and also must be differentiated from osteogenic sarcomas. On plain radiographs, Ewing's sarcoma appears as a lytic or mixed lytic-sclerotic, rarely as predominantly sclerotic lesion with margins Lodwick grade III. It is located primarily in the diaphyseal and metadiaphyseal regions of the long bones of the lower extremities. A large soft tissue tumor is usually present. Magnetic resonance imaging is the imaging modality of choice to evaluate the extent of the primary lesion, to monitor the response to neoadjuvant chemotherapy and to follow up non-resected Ewing's sarcomas. Bone scintigraphy is necessary to detect skeletal metastasis, and 201 thallium scanning has been shown to be sensitive in the monitoring of treatment response. Today, computed tomography is not longer used to image the tumor site; however, spiral CT of the lungs plays a central role as a staging and follow-up tool. (orig.) [de

    Improvements in survival for Ewing sarcoma pediatric and adolescent patients have been modest over the past 20 years. Combinations of anticancer agents endure as an option to overcome resistance to single treatments caused by compensatory pathways. Moreover, combinations are thought to lessen any associated adverse side effects through reduced dosing, which is particularly important in childhood tumors. Using a parallel phenotypic combinatorial screening approach of cells derived from three pediatric tumor types, we identified Ewing sarcoma-specific interactions of a diverse set of targeted agents including approved drugs. We were able to retrieve highly synergistic drug combinations specific for Ewing sarcoma and identified signaling processes important for Ewing sarcoma cell proliferation determined by EWS-FLI1 We generated a molecular target profile of PKC412, a multikinase inhibitor with strong synergistic propensity in Ewing sarcoma, revealing its targets in critical Ewing sarcoma signaling routes. Using a multilevel experimental approach including quantitative phosphoproteomics, we analyzed the molecular rationale behind the disease-specific synergistic effect of simultaneous application of PKC412 and IGF1R inhibitors. The mechanism of the drug synergy between these inhibitors is different from the sum of the mechanisms of the single agents. The combination effectively inhibited pathway crosstalk and averted feedback loop repression, in EWS-FLI1-dependent manner.

    With growing interest in resilience among mental health care providers globally, there is a need for a simple way to consider the complex interactions that predict adaptive coping when there is exposure to high levels of adversity such as family violence, mental illness of a child or caregiver, natural disasters, social marginalization, or political conflict. This article presents diagnostic criteria for assessing childhood resilience in a way that is sensitive to the systemic factors that influence a child's wellbeing. The most important characteristics of children who cope well under adversity and avoid problems like depression, PTSD, and delinquency are highlighted. A multidimensional assessment of resilience is presented that examines, first, the severity, chronicity, ecological level, children's attributions of causality, and cultural and contextual relevance of experiences of adversity. Second, promotive and protective factors related to resilience are assessed with sensitivity to the differential impact these have on outcomes depending on a child's level of exposure to adversity. These factors include individual qualities like temperament, personality, and cognitions, as well as contextual dimensions of positive functioning related to the available and accessibility of resources, their strategic use, positive reinforcement by a child's significant others, and the adaptive capacity of the environment itself. Third, an assessment of resilience includes temporal and cultural factors that increase or decrease the influence of protective factors. A decision tree for the diagnosis of resilience is presented, followed by a case study and diagnosis of a 15-year-old boy who required treatment for a number of mental health challenges. The diagnostic criteria for assessing resilience and its application to clinical practice demonstrate the potential usefulness of a systemic approach to understanding resilience among child populations. © 2014 Association for Child and

    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.

    The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.

    Rhabdomyosarcoma is the most common soft-tissue sarcoma in children; it can appear in any part of the body. Its biological behavior varies widely, and despite the absence of specific clinical or radiological characteristics, rhabdomyosarcoma should be taken into account in the differential diagnosis of solid tumors in children. This review focuses primarily on the imaging findings and anatomical distribution of the histological subtypes of childhood rhabdomyosarcoma and secondarily on the differential findings in histological studies.

    2011-04-01

    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.

The heavy ion therapy has advantages of its high dose distribution to the target and strong biological effect due to the Bragg peak formation and high linear energy transfer, respectively. The authors use carbon ion generated by Heavy Ion Medical Accelerator in Chiba (HIMAC) for the therapy of performance state 0-2 patients with the sarcomas unresectable, diagnosed pathologically, and of 60 y, 45% and teens, 8%) have been treated, whose tumor site has been the pelvis in 73%, volume >600 mL in 63%, tissue type of bone tumor in 70% (where cordoma has amounted to>200 cases). Five-year local control rate is found 71% and survival, 59%. In 175 therapeutically fresh cases with sacral cordoma of median age 67 y, with median clinical target volume 9 cm, treated with median dose 70.4 GyE/16 irradiations, the 8-y local control rate is found to be 69% and survival, 74%, within the median follow-up 54 months; with severe skin ulcer in 2 cases and deterioration of nervous dysfunction in 15 cases; suggesting the therapy is as effective and useful as surgical resection. At present, the therapy is not applicable to Japan health insurance. In the author's hospital, the heavy ion therapy has been conducted to total of >6,000 patients, which amounting to the largest number in the world. Now, 3 Japanese facilities can do the therapy as well and 3 countries in the world.(T.T.)

    Unplanned excision of sarcoma before referral to specialist centers can affect prognosis and surgical outcome. The diagnostic pathway of these patients is uncertain and needs to be reviewed. We aimed to describe patient and tumor characteristics, initial symptoms, initial and final diagnosis, and explore reasons for unplanned excision in this patient group. From a previous study on 258 sarcoma patients, we identified 64 patients referred after surgery. Medical records were reviewed. The majority were soft tissue sarcomas, most often with thoracic location. Leiomyosarcoma was the most frequent final diagnosis, lipoma, and fibroma/dermatofibroma the most frequent initial diagnoses. Fifty percent were superficial small tumors, and 60.9% had not received diagnostic imaging before surgery. Fifty percent were referred from public surgical departments, and 1/3 from private specialists. Twenty-three patients had initial presence of alarm symptoms registered before surgery, the remaining 2/3 fell outside referral criteria or alarm symptoms were not discovered. Patients referred after unplanned excision often have small superficial tumors and the majority fall outside of defined referral criteria. Referral criteria are not a guarantee for detection of all sarcomas and surgeons should always be aware of the possibility of malignancy when removing a tumor. © 2016 Wiley Periodicals, Inc.

    Ewing's sarcoma in childhood is a disease from family of the peripheral primitive neuroectodermal tumours. For a period of 16 y (1984-2000), 34 children with Ewing's sarcoma were treated and followed in our department. Twenty-seven of these patients were without distant metastases. Complex treatment was applied to all these patients-chemotherapy VACA (vincristine, actinomycin D, cyclophosphamide, adriamycin), local radiotherapy to a total dose of 50-56 Gy +/- surgery. After, a local tumour control was achieved in 11 children with non-metastatic Ewing's sarcoma, elective whole lung irradiation to a total dose of 12-15 Gy was applied. Our experience in these 11 patients with non-metastatic Ewing's sarcoma, in whom elective lung irradiation was applied, showed significant reduction in the lung metastases, improved free of disease survival and overall survival. The achieved good treatment results necessitate extending this treatment approach through defining the risk groups of patients, suitable for elective lung radiotherapy combined with chemotherapy in non-metastatic Ewing's sarcoma. © The Author 2015.

    Review of roentgenologic investigations into Kaposi's sarcoma is presented. It is shown that Kaposi's sarcoma is a disease injuring skin, osteal system, lungs and mediastinum, gastroeuteric tract and lymphatic nodes. Roentgenologic changes of soft tissues of limbs, osteal system, chest and gastroenteric tract organs are described. Manifestations of a tumor of any localization are quite different which makes it more difficult to perform roentgenologic diagnosis. An increase of Kaposi's sarcoma occurrence in patients suffering from aids as the disease increases is indicated

    A case of epithelioid sarcoma involving the soft tissue of the ankle is presented. The tumor was a hemorrhagic, fluid-filled, multiloculated lesion with inflammatory changes in the surrounding planes. Tuberculous abscess was diagnosed on the basis of the clinical picture, ultrasound and MRI findings. Surgical exploration of the ankle mass was carried out because of lack of local healing while the patient's general and pulmonary status improved on antituberculosis treatment. This was an unusual case of epithelioid sarcoma mimicking a multilocular abscess. (orig.)

    Objective: To document distribution of childhood malignancies among Paediatric Oncology patients. Study design: Descriptive study Place and duration of study: Department of Paediatric Oncology, Combined Military Hospital, Rawalpindi from June 2006 to May 2007. Methodology: We collected data of 141 consecutive newly diagnosed paediatric oncology patients. Demographics (age and gender) and types of malignancy (diagnosed on histopathology) were collected in all cases. Results: Of the total patients 90 were male, 51 female with a male to female ratio of 1.76. Childhood malignancies found were leukaemia (60.3%) lymphomas (11.3%), bone tumours (4.3%), brain tumours (2.8%), germ cell tumours (3.5%), retinoblastoma (7.1%), neuroblastoma (3.5%), Wilms tumour (2.8%), rhabdomyosarcoma (2.1%), hepatoblastoma (1.4%) and synovial sarcoma(0.7%).Mean age at diagnosis was 5.4 +- 3.05 years. 24 (17%) patients were from Punjab, 9 (6.4%) from Sindh, 82 (58.2%) from Khyber Pakhtunkhwa, 5 (3.5%) from Baluchistan and 21 (14.9%) from Azad Jammu and Kashmir (AJK). Conclusion: This study showed that distribution varies according to gender, age and geography. Leukemia is the commonest childhood malignancy. Our research findings are useful for prioritizing future childhood cancer research needs. (author)

    Full Text Available Charlotte Benson,1 Aisha B Miah1,2 1Sarcoma Unit, Royal Marsden Hospital, 2Department of Radiotherapy and Imaging, The Institute of Cancer Research, London, UK Abstract: Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade, undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases.

    Therapy success in bone sarcoma is significantly better compared to history cohorts with 60 - 70 % overall survival to date. Unfortunately, there is yet no shift and movement in better survival of patients with relapsed and refractory bone sarcomas during last twenty years. This article reviews targeted therapeutics for bone sarcomas which are under investigation and which could give chance to patients suffering from relapsed and chemo resistant bone sarcomas. Majority of the targeted drugs are given as part of phase 1 or 2 studies. (author)

    2009-01-01

    Purpose: To evaluate the applicability of carbon ion radiotherapy (CIRT) for unresectable retroperitoneal sarcomas with regard to normal tissue morbidity and local tumor control. Methods and Materials: From May 1997 to February 2006, 24 patients (17 male and 7 female) with unresectable retroperitoneal sarcoma received CIRT. Age ranged from 16 to 77 years (median, 48.6 years). Of the patients, 16 had primary disease and 8 recurrent disease. Histologic diagnoses were as follows: malignant fibrous histiocytoma in 6, liposarcoma in 3, malignant peripheral nerve sheath tumor in 3, Ewing/primitive neuroectodermal tumor (PNET) in 2, and miscellaneous in 10 patients. The histologic grades were as follows: Grade 3 in 15, Grade 2-3 in 2, Grade 2 in 3, and unknown in 4. Clinical target volumes ranged between 57 cm 3 and 1,194 cm 3 (median 525 cm 3 ). The delivered carbon ion dose ranged from 52.8 to 73.6 GyE in 16 fixed fractions over 4 weeks. Results: The median follow-up was 36 months (range, 6-143 months). The overall survival rates at 2 and 5 years were 75% and 50%, respectively. The local control rates at 2 and 5 years were 77% and 69%. No complications of the gastrointestinal tract were encountered. No other toxicity greater than Grade 2 was observed. Conclusions: Use of CIRT is suggested to be effective and safe for retroperitoneal sarcomas. The results obtained with CIRT were a good overall survival rate and local control, notwithstanding the fact that most patients were not eligible for surgical resection and had high-grade sarcomas.

    Granulocytic sarcoma, also known as myeloid sarcoma, is an extramedullary tumour composed of immature myeloid cells. Granulocytic sarcoma is typically found in patients with acute myeloid leukaemia, accelerated phase or blast crisis of chronic myeloid leukaemia, myelodysplastic syndrome, or as an isolated event without bone marrow involvement. We present a case of granulocytic sarcoma in a patient with chronic myeloid leukaemia in the setting of complete haematological, molecular and cytogenetic remission. Our patient was first treated with imatinib for chronic-phase chronic myeloid leukaemia. After maintaining remission for 42 months, he developed a granulocytic sarcoma in his spine. In this case report, we describe our case, along with the three other cases reported in the literature. In addition to being a rare diagnosis, this case demonstrates the importance of being vigilant in diagnosing the cause of back pain and atypical symptoms in patients with a history of leukaemia. 2014 BMJ Publishing Group Ltd.

    Full Text Available Synovial sarcoma (SS is a soft tissue, generally deep seated neoplasms that occurs generally in the proximity of large joints. We report of a case of a 33-year-old man who was diagnosed with primary SS of the kidney which is an extremely rare tumor that accounts for less than 2% of malignant renal tumors. Contemporary management of renal synovial sarcoma includes surgical resection and ifosfamide-based chemotherapy and they remain the mainstay of therapy of synovial sarcoma, which is often applied, combined as part of an aggressive treatment approach. Fewer than 50 patients have been described in the English literature. Physicians should be aware of the possibility of malignancy in cystic renal masses and raise the suspicion of synovial sarcoma, especially when patients with renal masses are young adults. Along with the case report a literature review on primary synovial sarcomas of the kidney is provided with focus on the renal tumors’ differential diagnosis.

    Improvements in survival for Ewing sarcoma pediatric and adolescent patients have been modest over the past 20 years. Combinations of anticancer agents endure as an option to overcome resistance to single treatments caused by compensatory pathways. Moreover, combinations are thought to lessen any associated adverse side effects through reduced dosing, which is particularly important in childhood tumors. Using a parallel phenotypic combinatorial screening approach of cells derived from three p...

    Full Text Available Abstract Background Sarcoma encompasses an uncommon group of cancer and the data is insufficient from Pakistan. We report our four years experience of Sarcoma of soft tissues and bones. Methods This cross sectional study was carried out at Aga Khan University Hospital from 2004 to 2008. The patients were divided into two groups from the outset i.e. initially diagnosed and relapsed group and separate sub group analysis was conducted. Results Out of 93 newly diagnosed patients, 58 belonged to bone sarcoma and 35 to soft tissue sarcoma group. While for relapsed patients, 5 had soft tissue sarcoma and 9 had bone sarcoma. Mean age was 32.5 years. At presentation, approximately two third patients had localised disease while remaining one third had metastatic disease. The Kaplan Meier estimate of median recurrence free survival was 25 months, 35 months, and 44 months for Osteogenic sarcoma, Ewing's sarcoma and Chondrosarcoma respectively. For Leiomyosarcoma and Synovial sarcoma, it was 20 and 19 months respectively. The grade of the tumour (p = 0.02 and surgical margin status (p = 0.001 were statistically significant for determination of relapse of disease. Conclusion The median recurrence free survival of patients in our study was comparable to the reported literature but with significant lost to follow rate. Further large-scale, multi centre studies are needed to have a more comprehensive understanding of this heterogeneous disease in our population.

    Full Text Available Abstract Background Bone mineral density (BMD accrual during childhood and adolescence is important for attaining peak bone mass. BMD decrements have been reported in survivors of childhood bone sarcomas. However, little is known about the onset and development of bone loss during cancer treatment. The objective of this cross-sectional study was to evaluate BMD in newly diagnosed Ewing's and osteosarcoma patients by means of dual-energy x-ray absorptiometry (DXA after completion of neoadjuvant chemotherapy. Methods DXA measurements of the lumbar spine (L2-4, both femora and calcanei were performed perioperatively in 46 children and adolescents (mean age: 14.3 years, range: 8.6-21.5 years. Mean Z-scores, areal BMD (g/cm2, calculated volumetric BMD (g/cm3 and bone mineral content (BMC, g were determined. Results Lumbar spine mean Z-score was -0.14 (95% CI: -0.46 to 0.18, areal BMD was 1.016 g/cm2 (95% CI: 0.950 to 1.082 and volumetric BMD was 0.330 g/cm3 (95% CI: 0.314 to 0.347 which is comparable to healthy peers. For patients with a lower extremity tumor (n = 36, the difference between the affected and non-affected femoral neck was 12.1% (95% CI: -16.3 to -7.9 in areal BMD. The reduction of BMD was more pronounced in the calcaneus with a difference between the affected and contralateral side of 21.7% (95% CI: -29.3 to -14.0 for areal BMD. Furthermore, significant correlations for femoral and calcaneal DXA measurements were found with Spearman-rho coefficients ranging from ρ = 0.55 to ρ = 0.80. Conclusions The tumor disease located in the lower extremity in combination with offloading recommendations induced diminished BMD values, indicating local osteopenia conditions. However, the results revealed no significant decrements of lumbar spine BMD in pediatric sarcoma patients after completion of neoadjuvant chemotherapy. Nevertheless, it has to be taken into account that bone tumor patients may experience BMD decrements or secondary osteoporosis

    Superficial soft-tissue sarcomas are malignant mesenchymal tumors located within the cutaneous and/or subcutaneous layers. Most superficial soft-tissue sarcomas are low-grade tumors; yet, the risk of local recurrence is high, and initial wide surgery is the main prognostic factor. Some of these superficial sarcomas may grow, following an infiltrative pattern, and their real extent may be underestimated clinically. Imaging techniques are useful to determine precisely the real margins of the tumor, especially in cases of clinically doubtful or recurrent or large superficial lesions. Imaging tools enable one to determine the relationship with the superficial fascia separating the subcutaneous layer from the underlying muscle. In our institution ultrasonographic examination is followed by magnetic resonance (MR) imaging when the size of the lesion exceeds 3-5 cm. Imaging assessment is performed prior to biopsy, enabling optimal surgical management. Imaging features of the main superficial sarcomas are detailed in the following article, according to their major locations: those arising in the epidermis and/or dermis, which are most often diagnosed by dermatologists, and the subcutaneous sarcomas.

    Therapeutic gastric irradiation has been used to reduce peptic juice secretion in patients with peptic ulcer disease. Between 1937 and 1968 a total of 2049 patients received such therapy at the University of Chicago. Three of these patients are known to have developed sarcomas in the field of radiation. Two gastric leiomyosarcomas of the stomach were diagnosed 26 and 14 years after treatment and a malignant fibrous histiocytoma of the anterior chest wall was removed six years after gastric irradiation. Of 743 peptic ulcer patients treated without irradiation and constituted as a control group for the study of therapeutic gastric radiation, none is known to have developed sarcoma. As the incidence of sarcoma in these patient groups is known only from the tumor registry of the University of Chicago, other cases of sarcoma may exist in the groups. While an increased incidence of sarcoma has not been proven to occur in patients who received therapeutic gastric irradiation for peptic ulcer disease, the possibility of such a risk should be borne in mind by physicians caring for such patients

    We report the case of a 59-year-old female with progressive bilateral painful swelling of the thighs. MRI revealed multiple intramuscular necrotic masses with similar morphologic patterns. Whole-body CT and 18-FDG PET-CT scans demonstrated additional hypermetabolic muscular masses and a lobulated lesion within the left atrial cavity. As biopsy of a muscular mass was compatible with a poorly differentiated sarcoma with MDM2 oncogene amplification, two diagnoses were discussed: a dedifferentiated liposarcoma with muscle and heart metastases or a primary cardiac sarcoma, mainly a cardiac intimal sarcoma, with muscular metastases, which was finally confirmed by array-comparative genomic hybridization (aCGH) in a sarcoma reference center. This case emphasizes the potential for intimal sarcoma to disseminate in skeletal muscle prior to any other organ and the need for a genomic approach in addition to classical radiopathologic analyses to distinguish primary from secondary locations facing simultaneous tumors of the heart and skeletal muscles with MDM2 amplification.

    AIMS: The development of sarcomas is a recognized complication of radiation therapy. We set out to retrospectively review the clinical and therapeutic demographics, as well as the cross-sectional imaging findings in patients with post-radiation sarcomas. MATERIALS AND METHODS: Sixty-three patients with post-radiation sarcomas were identified at a single institution. Computed tomography and/or magnetic resonance imaging was available for all patients. The medical records were reviewed for the primary diagnoses, the radiation history, and the latency period to the development of the sarcoma. RESULTS: There were 43 women and 20 men with a mean age of 52.8 years. The mean radiation dose delivered was 50.1 Gy, with a mean latency period for the development of the sarcoma of 15.5 years. The most common primary diagnoses were breast cancer, lymphoma and head and neck cancer. The most common sarcoma histopathologies were osteosarcoma and malignant fibrous histiocytoma. The most common imaging findings were a soft tissue mass and bone destruction. CONCLUSIONS: Post-radiation sarcomas, while uncommon, are not rare. The imaging findings are not pathognomonic, but an appreciation of the expected latency period may help to suggest the diagnosis. Sheppard, D.G. and Libshitz, H.I. (2001)

    Full Text Available Abstract Introduction Pulmonary artery intimal sarcoma is a rare disease with no characteristic symptoms. It is difficult to diagnose early and is frequently misdiagnosed as a pulmonary embolism. Case presentation Here we report a case of pulmonary artery intimal sarcoma in a 54-year-old woman presenting with complaints of shortness of breath on exertion. Echocardiography and a computed tomography scan showed that the right pulmonary artery trunk was blocked by a low-density mass. The patient was diagnosed with pulmonary artery intimal sarcoma by pathology and a complete mass resection was performed. After experiencing 10 months of disease-free survival, she was re-admitted because of the recurrence and metastasis of the tumor. Radiotherapy and chemotherapy were performed; however, only limited success was achieved. The patient died 15 months after the initial onset of symptoms. Conclusion Some patients with intimal sarcoma of the pulmonary artery can benefit from radiotherapy and chemotherapy as well as surgery.

    Primary malignant heart tumors represent rare entities where fibro sarcoma represents about 3% of all. Introducing the patient: A 15 years old patient with cardiac insufficiency (heart failure) symptoms, such as weakness, cyanosis, palpitations and breathing difficulties; enlargement of upper mediastinum and pleural effusion. Through echocardiography a pericardial effusion and intracavitary thrombus in atrium was diagnosed. With computed tomography is diagnosed a tumoral mass in right atrium which is also spread in the right ventricle of the heart. Tumor is completely removed; pat histology result showed primary fibro sarcoma of the heart. At that time no metastasis was found. Conclusion. Primary malignant heart tumors may manifest like cardiac insufficiency or like systemic diseases. Fibrosarcomas are rare and have bad prognosis. On average patients can live around six months after initial symptoms appeared and diagnosis of the tumor was done. In the case of cardiac insufficiency with differential diagnosis we should also think of heart tumors, which could certainly be proved for or eliminated by echocardiography.

    Full Text Available The epithelioid sarcoma (ES is an unusual variant of the sarcoma, not reaching 1% of all soft tissue sarcomas. Initially reported in 1970, it has a more aggressive variant, which was classified as the “proximal-type” in 1997. These are aggressive tumors with high rates of distant metastasis and local relapses. Isolated radio and chemotherapy responses are poor and free-margin surgical resection is the treatment of choice.This is the case report of a 25-year-old male patient diagnosed with “proximal-type” ES in the perineal region. He underwent surgical resection in another institution and was later admitted to our institution with local recurrence with rectal and left thigh muscle invasion. Neoadjuvant radio-chemotherapy was performed, followed by laparoscopic abdominoperineal rectal resection and partial left hemipelvectomy associated with left lower-limb amputation. The patient had no postoperative complications and is currently undergoing outpatient follow-up. The anatomopathological analysis showed tumor-free margins.The “proximal-type” ES is a rare soft-tissue sarcoma subtype. High local recurrence, as well as the metastasis rates, makes its treatment a challenging task.

    Full Text Available Ewing’s sarcoma is a common bone tumour of childhood but is a rare occurrence in individuals over 20 years of age. Few cases are reported as originating from peripheral nerves. We present an unusual case of extraosseous Ewing’s sarcoma originating from the sciatic nerve in a 66-year-old patient which had the clinical hallmarks of a benign nerve sheath tumour. Following discussion at a multidisciplinary meeting, excision biopsy of the suspected benign nerve sheath tumour was planned. At operation, the mass had malignant features. Histology confirmed the presence of Ewing’s sarcoma. Due to the morbidity of nerve resection, radiotherapy and chemotherapy were commenced. Ewing’s sarcoma is known to mimic benign pathologies. In this case there were subtle signs of a malignant process in the form of unremitting pain. It is vital to keep in mind the less common tumours that can affect the peripheral nervous system in such cases.

    Ewing's sarcoma is a malignant, round cell tumor arising from the bones and primarily affecting children and adolescent, accounting for 3 % of all childhood malignancies. Although the long bones and the trunk are typically affected, rare cases of it involving isolated bones throughout the body have been reported. Involvement of the skull bones is rare, constituting 1-6 % of the total Ewing's sarcoma cases but those affecting the cranial bones are rarer still, constituting only 1 %. We describe an 8 months old infant having Ewing sarcoma, of the petrous and mastoid parts of temporal bone along with the occipital bone, whose clinical presentation mimicked mastoiditis with facial nerve palsy. We discuss the clinical and therapeutic course of an extensive primary Ewing sarcoma of the temporal bone, which was treated without performing surgery and review this entity's literature in detail.

    To ascertain the effectiveness of IHC markers of vascular origin like CD31, CD34, FLI1 and ERG in vascular soft tissue sarcomas including angiosarcomas, Kaposi sarcomas, epithelioid hemangioendothelioma and a non-vascular soft tissue sarcoma (Epithelioid sarcoma). Descriptive study. Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from 2011 to 2017. Diagnosed cases of angiosarcomas (n=48), epithelioid hemangioendothelioma (n=9), Kaposi sarcoma (n=9) and epithelioid sarcoma (n=20) were selected. Immunohistochemical staining as performed on formalin fixed paraffin embedded sections. The sections were stained for the following markers: CD34 (VENTANA clone Q Bend 10), CD31 (Leica clone 1 A 10), FLI1 (CELL MARQUE clone MRQ-1) and ERG (CELL MARQUE clone EP111). A complete panel of CD34, CD31 and ERG was applied on 8/48 cases of angiosarcomas with triple positivity in 6 cases. Eight cases showed positivity for only CD31 and ERG and 2 cases showed positivity for only ERG. A complete panel of CD34, CD31 and ERG was applied on 3/9 cases of epithelioid hemangioendothelioma with positivity for all markers in 2 cases. Combined positivity for ERG and CD34 was seen in 2 cases and on 4 cases only CD31 immunohistochemical was solely applied with 100% positivity. FLI1 was not applied on any case. Among 9 cases of Kaposi sarcoma, ERG, CD34 and CD31 in combination were applied on only 1 case with triple positivity. Remaining cases show positivity for either CD34, CD31 or FLI1. Majority of cases of epithelioid sarcomas were diagnosed on the basis of cytokeratin and CD34 positivity with loss of INI1. The other vascular markers showed negativity in all cases. Among these four markers, ERG immunohistochemical stain is highly effective for endothelial differentiation due to its specific nuclear staining pattern in normal blood vessel endothelial cells (internal control) as well as neoplastic cells of vascular tumors and lack of background staining.

    Alveolar soft part sarcoma is a rare neoplasm usually arising in the soft tissues of the lower limbs in adults and in the head and neck region in children. It presents primarily as a slowly growing mass or as metastatic disease. It is characterized by a specific chromosomal alteration, der(17)t(X:17)(p11:q25), resulting in fusion of the transcription factor E3 (TFE3) with alveolar soft part sarcoma critical region 1 (ASPSCR1) at 17q25. This translocation is diagnostically useful because the tumor nuclei are positive for TFE3 by immunohistochemistry. Real-time polymerase chain reaction to detect the ASPSCR1-TFE3 fusion transcript on paraffin-embedded tissue blocks has been shown to be more sensitive and specific than detection of TFE3 by immunohistochemical stain. Cathepsin K is a relatively recent immunohistochemical stain that can aid in the diagnosis. The recent discovery of the role of the ASPSCR1-TFE3 fusion protein in the MET proto-oncogene signaling pathway promoting angiogenesis and cell proliferation offers a promising targeted molecular therapy.

  15. Kaposi sarcoma herpesvirus pathogenesis

    Koch, Sandra; Schulz, Thomas F.

    2017-01-01

    Kaposi sarcoma herpesvirus (KSHV), taxonomical name human gammaherpesvirus 8, is a phylogenetically old human virus that co-evolved with human populations, but is now only common (seroprevalence greater than 10%) in sub-Saharan Africa, around the Mediterranean Sea, parts of South America and in a few ethnic communities. KSHV causes three human malignancies, Kaposi sarcoma, primary effusion lymphoma, and many cases of the plasmablastic form of multicentric Castleman's disease (MCD) as well as occasional cases of plasmablastic lymphoma arising from MCD; it has also been linked to rare cases of bone marrow failure and hepatitis. As it has colonized humans physiologically for many thousand years, cofactors are needed to allow it to unfold its pathogenic potential. In most cases, these include immune defects of genetic, iatrogenic or infectious origin, and inflammation appears to play an important role in disease development. Our much improved understanding of its life cycle and its role in pathogenesis should now allow us to develop new therapeutic strategies directed against key viral proteins or intracellular pathways that are crucial for virus replication or persistence. Likewise, its limited (for a herpesvirus) distribution and transmission should offer an opportunity for the development and use of a vaccine to prevent transmission. This article is part of the themed issue ‘Human oncogenic viruses’. PMID:28893942

  16. Therapy of Ewing's sarcoma

    1993-01-01

    Therapy of Ewing's sarcoma requires a qualified clinical, radiological, and pathohistological diagnosis and, in particular, an optimal therapy by an experienced team of oncological specialists. Important prognostic factors are the presence of hematogenous metastases at diagnosis, the initial tumor volume, the response to chemotherapy, and adequate local therapy. Presently, cure rates of more than 60% can be achieved for localized Ewing's sarcoma by combination of local therapy and chemotherapy. The four-drug combination VACA (vincristin, actinomycin D, cyclophosphamide, adriamycin) can be considered as cytostatic gold standard. More aggressive regimens (VAIA, EVAIA, autologous bone marrow transplant) may be beneficial in subgroups and are under investigation. Concerning local therapy adequate radiotherapy plays a major role and achieves the same survival rates as radical surgery, comparable patient selection provided. Several factors have impact on radiotherapeutic results, especially total dose (45 Gy large volume, 55 Gy to the primary tumor), target volume (safety margin at least 2 cm according to the pretreatment volume, at least 5 cm in proximal and distal extension of long bones), timing of radiotherapy (as early as possible) and quality of treatment. Radiotherapy as sole local treatment is indicated in inoperable lesions (spine, sacrum, skull) and in small, good-responding tumors. High-risk patients should receive combined radiotherapeutic-surgical treatment, preferably as pre-operative irradiation. The value of hyperfractionation is not yet proven despite theoretical advantages. (orig.) [de

    Oxidative stress is characterised by an increased level of reactive oxygen species (ROS) that disrupts the intracellular reduction-oxidation (redox) balance and has been implicated in various diseases including cancer. Malignant tumors of connective tissue or sarcomas account for approximately 1% of all cancer diagnoses in adults and around 15% of paediatric malignancies per annum. There exists no information on the alterations of oxidant/antioxidant status of sarcoma patients in literature. This study was aimed to determine the levels of oxidative stress and antioxidant defence in patients with primary bone and soft tissue sarcoma and to investigate if there exists any significant differences in these levels between both the sarcomas. The study cohort consisted of 94 subjects; 20 soft tissue sarcoma, 27 primary bone sarcoma and 47 healthy controls. Malondialdehyde (MDA) and protein carbonyls were determined to assess their oxidative stress levels while antioxidant status was evaluated using catalase (CAT), superoxide dismutase (SOD), thiols and trolox equivalent antioxidant capacity (TEAC). Sarcoma patients showed significant increase in plasma and urinary MDA and serum protein carbonyl levels (p < 0.05) while significant decreases were noted in TEAC, thiols, CAT and SOD levels (p < 0.05). No significant difference in oxidative damage was noted between both the sarcomas (p > 0.05). In conclusion, an increase in oxidative stress and decrease in antioxidant status is observed in both primary bone and soft tissue sarcomas with a similar extent of damage. This study offers the basis for further work on whether the manipulation of redox balance in patients with sarcoma represents a useful approach in the design of future therapies for bone disease

    Myeloid sarcomas are extramedullary solid tumors composed of immature granulocytic precursor cells. In association with acute myeloid leukemia and other myeloproliferative disorders, they may arise concurrently with compromised bone marrow related to acute myeloid leukemia, as a relapsed presentation, or occur as the first manifestation. The testicles are considered to be an uncommon site for myeloid sarcomas. No therapeutic strategy has been defined as best but may include chemotherapy, radiotherapy and/or hematopoietic stem cell transplantation. This study reports the evolution of a patient with testicular myeloid sarcoma as the first manifestation of acute myeloid leukemia. The patient initially refused medical treatment and died five months after the clinical condition started.

    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.

  20. Postirradiation sarcoma in retinoblastoma. Induction or predisposition

    Schwarz, M.B.; Burgess, L.P.; Fee, W.E. Jr.; Donaldson, S.S.

    1988-01-01

    An alarmingly high rate of postirradiation sarcomas following treatment for retinoblastoma has been described in the literature. We present four new cases and report 57 others from the English literature. Osteogenic sarcoma was the predominant histologic type (58%), followed by fibrosarcoma (21%) and various other sarcomas (21%). The average latency period between irradiation and development of the second primary (sarcoma) was 12.4 years. Irrespective of irradiation, a genetic linkage between retinoblastoma and osteogenic sarcoma on the 13q14 chromosome is recognized. Through a pleiotropic effect of this same chromosome, a predisposition for other sarcomas may exist as well. Finally, a strong role for radiation induction is proposed for all of these postirradiation sarcomas. This is based on the increased number of sarcomas arising in the field of prior irradiation (sites uncharacteristic of spontaneously occurring primary sarcomas) and the prolonged latency periods.13 references

    2013-05-01

    Ewing's sarcoma is a relatively rare malignancy, occurring mainly between 4 and 25 years of age. It usually arises from the pelvis, followed by the femur, tibia, and remainder of both the long bones of the extremities and flat bones of the axial skeleton. To the best of our knowledge, Ewing's sarcoma of the patella has never been reported previously. Patellar tumors occur infrequently and represent an uncommon etiology of anterior knee pain. We describe the rare case of a 41-year-old man who presented with a 3-4 month history of escalating right anterior knee pain and swelling. Imaging demonstrated an aggressive patellar tumor with an adjacent soft tissue mass. The diagnosis of Ewing's sarcoma was confirmed by pathology. Physicians should be aware of atypical locations for Ewing's sarcoma and, conversely, of rare tumors arising in the patella and accounting for anterior knee pain. Early recognition of such malignancies allows prompt initiation of treatment, hence improving prognosis.

    Several studies have described an association between childhood maltreatment and inflammatory markers in the psychotic disorders (schizophrenia [SZ] and bipolar disorder [BD]). Previous studies have been relatively small (childhood abuse severity and clinical diagnosis on inflammatory markers were investigated in a large sample (n=483) of patients with a disorder on the psychosis spectrum and in healthy controls (HCs). Plasma levels of inflammatory markers (high-sensitivity C-reactive protein [hs-CRP], soluble tumor necrosis factor receptor type 1 [TNFR-R1], glycoprotein 130 [gp130]) were analyzed, and BMI and data on childhood trauma events, on the basis of the Childhood Trauma Questionnaire (CTQ), were obtained from all participants. Patients had increased levels of hs-CRP (Pchildhood maltreatment experiences (Pchildhood abuse (up to three types of abuse: sexual abuse, physical abuse, and emotional abuse) was associated with elevated BMI (f=8.46, Pchildhood abuse were found for elevated hs-CRP (f=4.76, P<0.001, Cohen's d=0.4). Differences among the groups disappeared when BMI was added to the model. Trauma-altered immune activation via elevated hs-CRP in patients with SZ and BD may be mediated by higher BMI; however, the direction of this association needs further clarification.

    2011-07-01

    Ewing's sarcoma is a highly aggressive bone and soft tissue tumor of children and young adults. At the molecular genetic level Ewing's sarcoma is characterized by a balanced reciprocal translocation, t(11;22)(q24;q12), which encodes an oncogenic fusion protein and transcription factor EWS/FLI. This tumor-specific chimeric fusion retains the amino terminus of EWS, a member of the TET (TLS/EWS/TAF15) family of RNA-binding proteins, and the carboxy terminus of FLI, a member of the ETS family of transcription factors. In addition to EWS/FLI, variant translocation fusions belonging to the TET/ETS family have been identified in Ewing's sarcoma. These studies solidified the importance of TET/ETS fusions in the pathogenesis of Ewing's sarcoma and have since been used as diagnostic markers for the disease. EWS fusions with non-ETS transcription factor family members have been described in sarcomas that are clearly distinct from Ewing's sarcoma. However, in recent years there have been reports of rare fusions in "Ewing's-like tumors" that harbor the amino-terminus of EWS fused to the carboxy-terminal DNA or chromatin-interacting domains contributed by non-ETS proteins. This review aims to summarize the growing list of fusion oncogenes that characterize Ewing's sarcoma and Ewing's-like tumors and highlights important questions that need to be answered to further support the existing concept that Ewing's sarcoma is strictly a "TET/ETS" fusion-driven malignancy. Understanding the molecular mechanisms of action of the various different fusion oncogenes will provide better insights into the biology underlying this rare but important solid tumor.

    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.

    The correlation between the effectiveness of radiation therapy and the histology of soft tissue sarcomas was investigated. Of 31 cases with a soft tissue sarcoma of an extremity treated by conservative surgery and postoperative radiation of 3,000-6,000 cGy, local recurrence occurred in 12; 5 out of 7 synovial sarcomas, 4 of 9 MFH, one of 8 liposarcomas, none of 4 rhabdomyosarcomas and 2 of 3 others. As for the histological subtyping, the 31 soft tissue sarcomas were divided into spindle cell, pleomorphic cell, myxoid and round cell type, and recurrence rates were 75%, 33.3%, 16.7% and 0%, respectively. From the remarkable difference in recurrent rate, it was suggested that round cell and myxoid type of soft tissue sarcomas showed a high radiosensitivity compared to the spindle cell type with low sensitivity. Clarifying the degree of radiosensitivity is helpful in deciding on the management of limb salvage in soft tissue sarcomas of an extremity. (author)

    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.

    2014-11-01

    Kaposi's sarcoma is significantly prevalent among men infected with the human immunodeficiency virus, accounting for >90% of all cases. The early presentation of KS typically involves mucocutaneous lesions and lymphadenopathy, and more advanced disease can affect the lungs and other organs. Our aim was to remind emergency physicians to remain suspicious of clinical presentations despite previous diagnoses or patient statements, particularly in patients with risk factors. We present a case of a young man having skin lesions and respiratory problems remaining undiagnosed, despite, and possibly due to, multiple recent physician contacts. Respiratory illnesses are common presentations in the emergency department and are typically benign and attributed to viral causes. However, the emergency physician must always be on the look out for more dangerous causes of respiratory complaints, especially in patients with risk factors and in those found to be refractory to recent treatment for more common illnesses.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    Benson, Charlotte; Miah, Aisha B

    2017-01-01

    Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade), undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types. There is a role of adjuvant treatment in carefully selected cases following multidisciplinary discussion at sarcoma reference centers. In patients with metastatic disease, systemic chemotherapy can then be considered. There is activity of a number of agents, including doxorubicin, trabectedin, gemcitabine-based chemotherapy, eribulin and pazopanib. Patients should be considered for clinical trial entry where possible. Close international collaboration is important to allow progress in this group of diseases. PMID:28919822

    Metastatic Ewing's sarcoma to the central nervous system is an uncommon condition and debate concerning the true origin of its metastases is still up to date. To the best of our knowledge, only two cases of dural metastatic Ewing's sarcoma have been published in the English medical literature. We present an additional case in a 24-year-old female and discuss the pathogenesis of these unusual tumors with review of the relevant literature concerning their treatment and outcome. A 24-year-old female with previous history of pelvis Ewing's sarcoma and recently discovered lung metastases, presented with moderate headache for the past 2 weeks and weakness in her left leg for the past 2 days. Computed tomography scan and magnetic resonance imaging revealed an extra-axial right frontoparietal mass invading the superior sagittal sinus but with clear delineation with brain parenchyma. Imaging features were suggestive of a meningioma as no abnormalities in the skull abutting to the tumor were noted. The patient underwent surgical removal of her tumor. Near total resection was achieved and histological examination showed evidence of metastatic Ewing's sarcoma. Postoperative adjuvant radiation and chemotherapy were administered. The patient improved well postoperatively with full recovery of her motor weakness. She is symptom free with no signs of progression, at most recent follow-up, 8 months after surgery. Despite its rarity, metastatic Ewing's sarcoma must be considered in the differential diagnosis of extra-axial dural masses particularly meningiomas.

    Of 255 cases of Ewing's sarcoma recorded at the Bone Tumor Center of the Rizzoli Orthopaedic Institute, 78 patients (irradiated and with a follow-up of longer than3 years) were considered ''at risk'' for the development of a second radio-induced sarcoma (RIS). Three of the 78 patients developed an RIS in the irradiated field. Theoretical and statistical analyses were carried out considering different modalities of local treatment. Statistically, the only significant factor was related to the irradiation dose. Surgical resection seems to prevent RIS

    Full Text Available Kaposi’s sarcoma is a vascular tumour of the skin, most frequently seen in men over 50 years of age, of long-term progress and low mortality. It is related to the infection caused by the human immunodeficiency virus (HIV; it appears in the advanced stages of the disease and with immunosuppression, affecting approximately 20 % of the people with HIV who do not take antiretroviral drugs. This is a case of an urban female patient who did not have a history of disease and who began to have squamous erythematous lesions on the right foot and on the thighs. A skin biopsy was performed and the patient was diagnosed with a Kaposi’s sarcoma. The patient was HIV-negative. This case is presented as it is a rare condition in an HIV-negative patient.

    2017-06-01

    Extraskeletal Ewing's sarcoma (EES) is a rare finding in comparison with Ewing's sarcoma of bone and usually manifests in young patients. However, even in older patients, one must consider the diagnosis. In this case, we describe a 52-year-old woman diagnosed with EES, mimicking as adenocarcinoma of the sigmoid. The tumor was not visualized by a multi-slice spiral computed tomography of the abdomen and pelvis with intravenous contrast, and eventually the diagnosis was made by positive immunohistochemical staining for CD99 and by molecular testing for EWSR1 translocation. This combination of the patient's age and the localization of the tumor mimicking an adenocarcinoma of the sigmoid has never been described before.

    Full Text Available Introduction. Kaposi sarcoma is an angioproliferative disorder that requires infection with human herpesvirus 8 (HHV-8 for its development. The majority of cases are associated with HIV infection or other immunocompromising conditions. Thymomas are occasionally associated to cytopenia, which may alter the patients’ immune responses. Methods. Case report using clinical records. Results. Case report of a 46-year-old male patient diagnosed with thymoma and myasthenia gravis. The patient was referred to an otolaryngology consultation with complaints of facial pain in the right malar region, interpreted as an acute sinusitis. Following examination, an expansive maxillary sinus mass was found, and endoscopic surgery was undertaken. After careful investigation, it was diagnosed as a Kaposi sarcoma. Conclusions. It is thought to be the first described case of a maxillary sinus Kaposi sarcoma in an HIV-negative patient. Thus, this entity has to be considered in the differential diagnosis of sinus masses, even in non-HIV patients.

    2010-01-01

    Radiotherapy plays an important role in the treatment of cancers. However, exposure to ionizing radiation is a well-known risk factor for secondary cancer development. Currently, rigorous defined scientific criteria are lacking to establish if an individual tumor has a radiation-induced or a sporadic origin. The main aim of my thesis program was to identify a transcriptome signature of the ionizing radiation effects in radiation-induced cancers. The series of cancers used in this study is composed of sarcomas developing in the irradiation field of patients treated by radiotherapy for a primary cancer. Strict selection criteria (histology different from the primary cancer, latency longer than 5 years) were used to establish with a high probability the sarcomas-radiation induced origin. Their transcriptomes were compared with those from patients without irradiation history. A method of classification adapted to small series was used for the study of all the 60 collected sarcomas (34 radiation-induced and 26 sporadic). A learning set composed of 24 sarcomas from known aetiology allowed us to determine a signature of 135 genes discriminating the sarcomas according to their aetiology. The signature classified 86% of the remaining sarcomas as a function of their aetiology with an accuracy of 97%. The analysis of the genes-function shows that the radiation-induced sarcomas suffered the effects of a chronic oxidative stress mainly generated by mitochondrial dysfunctions. This study shows, for the first time, that it is possible to diagnose, at the case by case level, radiation-induced sarcomas on a rigorous scientific basis. (author)

    Postradiation sarcomas arising many years after treatment of cancer are long term sequelae of therapy. We describe the clinical features, radiographic findings, and results of treatment in 13 patients with such sarcomas encountered over a 6-year period. Of these patients, 9 had bone sarcomas and the remaining 4 had paraspinal tumors arising from adjacent soft tissue and nerve. The primary cancer for which radiation was given included Hodgkin's disease (4 patients), breast cancer (2 patients), cervix cancer (2 patients), and a variety of others (5 patients). The latent interval to the occurrence of the second neoplasm varied from 6 to 30 years (median, 10 years) after treatment of the original tumor. Despite aggressive treatment, the overall prognosis was poor. The median survival was 8 months, with only 3 surviving more than 2 years. Although rare, postradiation sarcoma should be considered in the differential diagnosis of patients presenting with late onset of spinal pain or neurological symptoms after clinical remission of an original cancer

    Full Text Available Background: Monophasic fibrous synovial sarcoma (SS is the most common variant of SS. Only a few cytological studies are available on this entity. Bcl-2 protein expression has been described as a characteristic marker of SS and is useful for its differentiation from other sarcomas. Cytokeratin and CD99 are also used in detecting SS. Aims: To evaluate synovial sarcoma and its variants cytomorphologically. Materials and Methods: During a period of 10 years 7 months, i.e. from January 1998 to July 2008, 12 cytologic specimens diagnosed as synovial sarcoma were reviewed. Ten cases were diagnosed as SS on aspiration alone but two cases required ancillary technique i.e., immunocytochemistry staining with bcl-2 and cytokeratin. The smears were stained with Papanicolaou and May-Grόnwald-Giemsa stains. Results: All cytologic specimens in our study had similar appearance. Most smears were highly cellular and were made up of densely packed tri-dimensional groups and singly scattered round to oval cells. Cellular monomorphism and vascular channels within the cell groups were the remarkable findings. Only one case showed cytologic evidence of epithelial differentiation. Bcl-2, cytokeratin, CD99 positivity was seen on immunohistochemistry staining. Results were categorized according to age, sex and morphologic variants. Conclusions: Although cytomorphologic features of synovial sarcomas are characteristic enough to permit its recognition, clinical correlation is necessary for accurate diagnosis. Monophasic variant is the most common entity observed in the present study.

    Primary Ewing's sarcoma originating in the pericranium is an extremely rare disease entity. A 9-year-old female patient was admitted to our department due to a left temporal subcutaneous mass. The mass was localized under the left temporal muscle and attached to the surface of the temporal bone. Head computed tomography revealed a mass with bony spicule formation on the temporal bone, however, it did not show bone destruction or intracranial invasion. F-18 fluorodeoxyglucose positron emission tomography showed no lesions other than the mass on the temporal bone. Magnetic resonance imaging showed that the mass was located between the temporal bone and the pericranium. The mass was completely resected with the underlying temporal bone and the overlying deep layer of temporal muscle, and was diagnosed as primary Ewing's sarcoma. Because the tumor was located in the subpericranium, we created a new classification, "pericranial Ewing's sarcoma," and diagnosed the present tumor as pericranial Ewing's sarcoma. We herein present an extremely rare case of primary pericranial Ewing's sarcoma that developed on the temporal bone.

    Abstract - The incidence of malignancies in virus carriers acquired immunodeficiency (HIV) has increased in conjunction with the disease during the past decade. 40% of all AIDS patients develop cancer during the course of HIV infection. Kaposi's sarcoma (KS), Non-Hodgkin lymphoma (NHL) and cervical cancer have an impact extremely high in HIV infected patients, and they are considered as disease AIDS-defining stage. Many reports suggest that other neoplasms they can have a high impact on the population of HIV carrier, including head and neck carcinoma, rectal cancer - anal, plasma cytomas, and melanoma lung cancer. Methods - We examined the spectrum of cancer in HIV-infected patients, specifically neoplasms except Kaposi sarcoma diagnosed between 1/1998 - 6/2004. Information on age, sex, factors was gathered risk for AIDS, neoplasms and mortality rate. Results: The total number of patients in our study was 21 patients, what 15 were male (71%) and 6 females (29%); the median age was 36 (29-70). Tumors were reported: 11 Non-Hodgkin lymphomas (52%), 2 Hodgkin's lymphoma (6.6%), 1 medullary thyroid cancer (6.6%), 1 melanoma (6.6%), 1 rectal cancer (5%) and three head and neck cancers (14%), 1 cancer 1 lung and breast cancer. Five of the patients were intravenous drug abusers (24%); 4 patients were homosexual, bisexual March 8 straight, on 6 patients know the data. Conclusions - The spectrum of malignancies associated with infection HIV in our study was similar to that described in other populations. ratio between the immune system and the epidemiology of the virus-induced tumors is to importance to identify new therapeutic approaches in the treatment and / or prevention of these neoplasms

    Rhabdomyosarcoma (RMS) is the commonest paediatric soft-tissue sarcoma constituting 3-5% of all malignancies in childhood. RMS has a predilection for the head and neck area and tumours in this location account for 40% of all childhood RMS cases. In this review we address the clinical and imaging presentations of craniofacial RMS, discuss the most appropriate imaging techniques, present characteristic imaging features and offer an overview of differential diagnostic considerations. Post-treatment changes will be briefly addressed. (orig.)

    Full Text Available Objective: Better methods are needed for the accurate detection of child tuberculosis (TB. This study compared different laboratory tests and evaluated IS6110 PCR for the detection of Mycobacterium tuberculosis (MTB among clinically diagnosed child TB patients. Methods: A total of 102 paediatric patients (<15 years old with clinically diagnosed TB were enrolled in this study. The patients were admitted to the icddr,b hospital in Dhaka between 2003 and 2005. Sputum/gastric lavage samples were collected for smear microscopy, culture (solid/Lowenstein–Jensen medium and liquid/MGIT, and IS6110 PCR testing. The sensitivity, specificity, and positive and negative predictive values (PPV, NPV of smear microscopy and PCR were compared to the two culture methods. Results: Three patients were positive on smear microscopy (2.9%. MTB was detected by conventional culture in 15.7% (16/102, liquid culture in 14% (14/100, and IS6110 PCR in 61.8% (63/102. PCR detected an additional 45 patients who were undetected with the three other tests. Compared to conventional and liquid culture, respectively, smear microscopy showed sensitivity of 18.8% and 21.4%, specificity of 100% individually, PPV of 100% individually, and NPV of 86.9% and 88.7%, whereas PCR had sensitivity of 87.5% and 92.9%, specificity of 43% individually, PPV of 22.2% and 21%, and NPV of 94.9% and 97.4%. Conclusions: PCR can be useful compared to smear microscopy and culture methods and is applicable as a rapid screening test for child TB. A larger scale study is required to determine its diagnostic efficacy in improving the detection of child TB in the presence and absence of severe malnutrition.

    Ewing's sarcoma in childhood is a disease from family of the peripheral primitive neuroectodermal tumours. For a period of 16 y (1984-2000), 34 children with Ewing's sarcoma were treated and followed in our department. Twenty-seven of these patients were without distant metastases. Complex treatment was applied to all these patients-chemotherapy VACA (vincristine, actinomycin D, cyclophosphamide, adriamycin), local radiotherapy to a total dose of 50-56 Gy ± surgery. After, a local tumour control was achieved in 11 children with non-metastatic Ewing's sarcoma, elective whole lung irradiation to a total dose of 12-15 Gy was applied. Our experience in these 11 patients with non-metastatic Ewing's sarcoma, in whom elective lung irradiation was applied, showed significant reduction in the lung metastases, improved free of disease survival and overall survival. The achieved good treatment results necessitate extending this treatment approach through defining the risk groups of patients, suitable for elective lung radiotherapy combined with chemotherapy in non-metastatic Ewing's sarcoma.

    Fagone, Paolo; Nicoletti, Ferdinando; Salvatorelli, Lucia; Musumeci, Giuseppe; Magro, Gaetano

    2015-10-01

    Recent immunohistochemical analyses have showed that cyclin D1 is expressed in soft tissue Ewing's sarcoma/peripheral neuroectodermal tumor (PNET) of childhood and adolescents, while it is undetectable in both embryonal and alveolar rhabdomyosarcoma. In the present paper, microarray analysis provided evidence of a significant upregulation of cyclin D1 in Ewing's sarcoma as compared to normal tissues. In addition, we confirmed our previous findings of a significant over-expression of cyclin D1 in Ewing sarcoma as compared to rhabdomyosarcoma. Bioinformatic analysis also allowed to identify some other genes, strongly correlated to cyclin D1, which, although not previously studied in pediatric tumors, could represent novel markers for the diagnosis and prognosis of Ewing's sarcoma/PNET. The data herein provided support not only the use of cyclin D1 as a diagnostic marker of Ewing sarcoma/PNET but also the possibility of using drugs targeting cyclin D1 as potential therapeutic strategies.

    Full Text Available BACKGROUND: Ewing Sarcoma Family Tumours (ESFT are rare in early childhood. The aim of this study was to report the clinical characteristics and outcome of children under 6 years of age affected by ESFT of the bone in Italy. METHODS: The records of all the children diagnosed with osseous ESFT in centres members of the Associazione Italiana di Ematologia ed Oncologia Pediatrica (AIEOP from 1990 to 2008 were reviewed. The Kaplan-Meier method was used for estimating overall and progression-free survival (OS, PFS curves; multivariate analyses were performed using Cox proportional hazards regression model. RESULTS: This study includes 62 patients. An axial primary localization was present in 66% of patients, with the primary site in the chest wall in 34%. Fourteen (23% patients presented metastatic disease. The 5-year OS and PFS were 73% (95% confidence interval, CI, 58-83% and 72% (95% CI 57-83% for patients with localized disease and 38% (95% CI 17-60% and 21% (95% CI 5-45% for patients with metastatic disease. Metastatic spread, skull/pelvis/spine primary localization, progression during treatment and no surgery predicted worse survival (P<0.01, while patients treated in the last decade had better survival (P = 0.002. In fact, the 5-year OS and PFS for patients diagnosed in the period 2000-2008 were 89% (95% CI 71-96% and 86% (95% CI 66-94%, respectively. CONCLUSION: The axial localization is the most common site of ESFT in pre-scholar children. Patients treated in the most recent period have an excellent outcome.

    A 38-year-old male presented to the emergency department with abdominal pain and bulge. He had a history of irritable bowel syndrome for 1 year with complaint of dyspepsia. Physical examination revealed a distended abdomen with a huge palpable mass located in the paraumblical region. Laboratory findings revealed a high white blood cell count with neutrophil predominance. Contrast-enhanced computed tomography (CT) showed a 23-cm, oval-shaped, grossly necrotic, low-attenuation mass with peripherally located dominant vessels. Magnetic resonance imaging (MRI) with diffusion weighted imaging (DWI) suggested a highly malignant tumor with prominent diffusion restriction especially at the periphery of the mass. On surgery, macroscopic examination showed a macrolobulated, hypervascular, reddish brown mass attached to the parietal peritoneum with a stalk. Ewing's sarcoma (ES) was diagnosed on histopathological examination with small round cells.

    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 Abnormal vaginal bleeding, tumors located mainly in the uterine cavity, ill-defined tumor margins, and mean apparent diffusion coefficient values 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.

    Françoise Ducimetière

    Full Text Available BACKGROUND: The exact overall incidence of sarcoma and sarcoma subtypes is not known. The objective of the present population-based study was to determine this incidence in a European region (Rhone-Alpes of six million inhabitants, based on a central pathological review of the cases. METHODOLOGY/PRINCIPAL FINDINGS: From March 2005 to February 2007, pathology reports and tumor blocks were prospectively collected from the 158 pathologists of the Rhone-Alpes region. All diagnosed or suspected cases of sarcoma were collected, reviewed centrally, examined for molecular alterations and classified according to the 2002 World Health Organization classification. Of the 1287 patients screened during the study period, 748 met the criteria for inclusion in the study. The overall crude and world age-standardized incidence rates were respectively 6.2 and 4.8 per 100,000/year. Incidence rates for soft tissue, visceral and bone sarcomas were respectively 3.6, 2.0 and 0.6 per 100,000. The most frequent histological subtypes were gastrointestinal stromal tumor (18%; 1.1/100,000, unclassified sarcoma (16%; 1/100,000, liposarcoma (15%; 0.9/100,000 and leiomyosarcoma (11%; 0.7/100,000. CONCLUSIONS/SIGNIFICANCE: The observed incidence of sarcomas was higher than expected. This study is the first detailed investigation of the crude incidence of histological and molecular subtypes of sarcomas.

    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. PMID:25954672

  8. Procholecystokinin as marker of human Ewing sarcomas

    2004-01-01

    PURPOSE: Ewing sarcoma is a rapidly growing mesenchymal tumor in young adults. Although it was shown previously to express the cholecystokinin (CCK) gene, it is unknown whether CCK gene expression is detectable at protein level in Ewing sarcoma tumor cell lines, in tumor tissue, and in plasma from...... Ewing sarcoma patients, and, if so, whether CCK peptides might play a role as tumor markers. EXPERIMENTAL DESIGN: CCK gene expression was evaluated with in situ hybridization or reverse transcription-PCR in tumor tissue. CCK precursors and bioactive CCK were measured with specific RIAs in tumor tissue......, in cell culture medium, and in plasma of Ewing sarcoma patients before and after chemotherapy as well as after tumor recurrence. RESULTS: CCK mRNA was identified in 12 Ewing sarcoma biopsies sampled in two series and in four Ewing sarcoma cell lines but not in unrelated neoplasia. Immunoreactive pro...

    Full Text Available New therapies are needed to improve survival for patients with Ewing sarcoma. Over the past decade, camptothecin agents such as topotecan and irinotecan have demonstrated activity against Ewing sarcoma, especially in combination with alkylating agents. Previous studies have shown camptothecin-based combinations to be tolerable outpatient strategies that are attractive for salvage therapy. This paper highlights important issues related to drug dosing, schedule of administration, pharmacokinetics, toxicity, and activity of commonly used camptothecin-based regimens. Also discussed are strategies for incorporating these regimens into therapy for newly diagnosed patients, including several potential possibilities for combination with targeted agents.

    Full Text Available We describe an exceptional case of erythroid sarcoma in a pediatric patient as a growing orbital mass with no evidence of morphologic bone marrow involvement, who was finally diagnosed of pure erythroid sarcoma based on histopathology and flow cytometry criteria. We discuss the contribution of standardized eight-color flow cytometry as a rapid and reliable diagnostic method. The use of normal bone marrow databases allowed us to identify small aberrant populations in bone marrow and later confirm the diagnosis in the neoplastic tissue.

    Better methods are needed for the accurate detection of child tuberculosis (TB). This study compared different laboratory tests and evaluated IS6110 PCR for the detection of Mycobacterium tuberculosis (MTB) among clinically diagnosed child TB patients. A total of 102 paediatric patients (PCR testing. The sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of smear microscopy and PCR were compared to the two culture methods. Three patients were positive on smear microscopy (2.9%). MTB was detected by conventional culture in 15.7% (16/102), liquid culture in 14% (14/100), and IS6110 PCR in 61.8% (63/102). PCR detected an additional 45 patients who were undetected with the three other tests. Compared to conventional and liquid culture, respectively, smear microscopy showed sensitivity of 18.8% and 21.4%, specificity of 100% individually, PPV of 100% individually, and NPV of 86.9% and 88.7%, whereas PCR had sensitivity of 87.5% and 92.9%, specificity of 43% individually, PPV of 22.2% and 21%, and NPV of 94.9% and 97.4%. PCR can be useful compared to smear microscopy and culture methods and is applicable as a rapid screening test for child TB. A larger scale study is required to determine its diagnostic efficacy in improving the detection of child TB in the presence and absence of severe malnutrition. Copyright © 2018 The Authors.

      We report three cases of Landau-Kleffner syndrome (LKS) in children (two females, one male) in whom diagnosis was delayed because the sleep electroencephalography (EEG) was initially normal.   Case histories including EEG, positron emission tomography findings, and long-term outcome were reviewed.   Auditory agnosia occurred between the age of 2 years and 3 years 6 months, after a period of normal language development. Initial awake and sleep EEG, recorded weeks to months after the onset of language regression, during a nap period in two cases and during a full night of sleep in the third case, was normal. Repeat EEG between 2 months and 2 years later showed epileptiform discharges during wakefulness and strongly activated by sleep, with a pattern of continuous spike-waves during slow-wave sleep in two patients. Patients were diagnosed with LKS and treated with various antiepileptic regimens, including corticosteroids. One patient in whom EEG became normal on hydrocortisone is making significant recovery. The other two patients did not exhibit a sustained response to treatment and remained severely impaired.   Sleep EEG may be normal in the early phase of acquired auditory agnosia. EEG should be repeated frequently in individuals in whom a firm clinical diagnosis is made to facilitate early treatment. © The Authors.

  14. Endosialin and Associated Protein Expression in Soft Tissue Sarcomas: A Potential Target for Anti-Endosialin Therapeutic Strategies

    Directory of Open Access Journals (Sweden)

    Daniel J. O’Shannessy

    2016-01-01

    Full Text Available Endosialin (CD248, TEM-1 is expressed in pericytes, tumor vasculature, tumor fibroblasts, and some tumor cells, including sarcomas, with limited normal tissue expression, and appears to play a key role in tumor-stromal interactions, including angiogenesis. Monoclonal antibodies targeting endosialin have entered clinical trials, including soft tissue sarcomas. We evaluated a cohort of 94 soft tissue sarcoma samples to assess the correlation between gene expression and protein expression by immunohistochemistry for endosialin and PDGFR-β, a reported interacting protein, across available diagnoses. Correlations between the expression of endosialin and 13 other genes of interest were also examined. Within cohorts of soft tissue diagnoses assembled by tissue type (liposarcoma, leiomyosarcoma, undifferentiated sarcoma, and other, endosialin expression was significantly correlated with a better outcome. Endosialin expression was highest in liposarcomas and lowest in leiomyosarcomas. A robust correlation between protein and gene expression data for both endosialin and PDGFR-β was observed. Endosialin expression positively correlated with PDGFR-β and heparin sulphate proteoglycan 2 and negatively correlated with carbonic anhydrase IX. Endosialin likely interacts with a network of extracellular and hypoxia activated proteins in sarcomas and other tumor types. Since expression does vary across histologic groups, endosialin may represent a selective target in soft tissue sarcomas.

    1997-02-01

    Pulmonary Kaposi's sarcoma (KS) is one of the many manifestations of AIDS. There are no specific tests for its early diagnosis. Because its symptoms may be similar to tuberculosis, it may be diagnosed incorrectly and treated as such. Consequently, by the time of the correct diagnosis, valuable time will have been lost for effective medical care that could positively impact prognosis. The discussion in this case study is focused on pulmonary KS with an interest in improving premorbid diagnosis that may lead to an earlier recognition and better treatment of the disease.

    Full Text Available Synovial sarcomas are soft-tissue malignancies with a poor prognosis and propensity for distant metastases. Although originally believed to arise from the synovium, these tumors have been found to occur anywhere in the body. We report a rare case of synovial sarcoma arising from the median nerve. To our knowledge, this is the twelfth reported case of intraneural synovial sarcoma, and only the fourth arising from the median nerve. Because the diagnosis may not be apparent until after pathological examination of the surgical speci­men, synovial sarcoma should be kept in mind when dealing with what may seem like a benign nerve tumor.

    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.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    A 76-year-old man was treated with bilateral orchiectomy, estramustine phosphate and pelvic irradiation for prostate cancer. Osteogenic sarcoma of the prostate developed 18 months after the treatment. Postmortem examination revealed that the tumor was 8 cm in diameter and had infiltrated into the bladder and rectal walls and had resulted in peritoneal dissemination. There was no distant metastasis. Macroscopically, the tumor was ashen, firm and relatively homogenous and diffusely spread. Histologically, it was composed of spindle and pleomorphic cells, which were making osteoid with calcification. There was no ordinary tubular formation as shown in adenocarcinoma of the prostate. No positive immunostaining for prostate-specific antigen, epithelial membrane antigen and cytokeratin (AE-1, AE-3) were confirmed. Positive immunostaining for nonepithelial marker vimentin was confirmed. The ultimate diagnosis was osteogenic sarcoma of the prostate. (author)

    Case History and Findings: A 73-year-old woman with a history of myeloproliferative syndrome (MPS) presented with bilateral chemosis, redness and burning of the eyes. The ocular motility was severely impaired. Ophthalmological examination revealed markedly distended conjunctivas on both sides. Biopsy disclosed conjunctival granulocytic sarcoma as an initial symptom of acute myelogenous leukemia (AML). Diagnosis was confirmed by peripheral blood smear and bone marrow aspiration. Treatment and Outcome: The orbital tumor disappeared completely after local external beam irradiation with a total dose of 30 Gy and no further orbital recurrence occurred. With chemotherapy following irradiation transient hematological remission was achieved. 5 months after diagnosis the patient died of respiratory failure following atypical pneumonia as a consequence of her underlying disorder. Conclusion: Detection of orbital granulocytic sarcoma, even in the absence of typical leukemic symptoms is of practical importance, because treatment with irradiation can lead to stabilization or improvement in the patient's vision.

    Full Text Available Introduction Fibromyxoid sarcoma is a rare mesenchymal neoplasm, usually appearing in the soft tissue of the extremities, less frequently in the groin, trunk, neck, and upper extremities. Within the abdomen, the tumour is usually localised within the retroperitoneum. Case OutlineWe present a 56-year-old woman in whom, during the routinely performed investigation for atacks of choking with lots of bronchial secretion, and arterial hypertension, an ultrasonographer found a tumour within the head of the pancreas 6×6 cm in diameter. At operation, a dark pink, lobulated soft tumour, surrounded by a tiny capsule, clearly different from the completely normal pancreatic tissue of the posterior side of the head of the pancreas, was easily and ideally excised.The postoperative recovery was stormy. She developed postoperative pancreatitis, temporary biliary and duodenal fistula, which all settled by conservative treatment. The histology of the 80 g weighing tumour showed a circumscribed fibromyxoid sarcoma of low malignancy. Immunohistochemistry showed diffuse vimentin and CD34 strong positivity, as well as focal anti-SMA and anti-EMA immunopositivity. Six months after surgery, she died with signs of cerebrovascular insult, asthmatic status, and recurrent suppurative abdominal fistula, probably related to the previous pancreatitis. Ultrasonography showed a possible liver secondary. The exact cause of death was not confirmed as the autopsy was refused by the family. Conclusion Primary sarcomas of the pancreas are very rare, but should be considered in differential diagnosis of pancreatic neoplasms. To the best of our knowledge, there has been no previously described fibromyxoid sarcoma of the pancreas. .

    The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma. Chemotherapy included 8 cycles of doxorubicin, vincristine, and cyclophosphamide, with alternating cycles of etoposide and ifosfamide. A year later, a second wide excision of the mass was performed, followed by bilaminate skin substitute and skin graft placement for reconstruction of the soft-tissue defect. After chemotherapy, a follow-up PET scan showed no signs of re-uptake in any soft tissue or skeletal structures. After 2 years, the patient remains in complete remission.

    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

    Full Text Available Extraosseous Ewing’s sarcoma (EES involving the central nervous system is rare, but can be diagnosed and distinguished from other primitive neuroectodermal tumors (PNET by identification of the chromosomal translocation (11;22(q24;q12. We report EES arising from the spinal intradural extramedullary space, based on imaging, histopathological, and molecular data in two men, ages 50 and 60 years old and a review of the literature using PubMed (1970-2009. Reverse transcriptase polymerase chain reaction (RT-PCR identified the fusion product FL1-EWS. Multimodal therapy, including radiation and alternating chemotherapy including vincristine, cyclophosphamide, doxorubicin and ifosfamide and etoposide led to local tumor control and an initial, favorable therapeutic response. No systemic involvement was seen from the time of diagnosis to the time of last follow-up (26 months or death (4 years. This report confirms that EES is not confined to the earliest decades of life, and like its rare occurrence as an extra-axial meningeal based mass intracranially, can occasionally present as an intradural mass in the spinal canal without evidence of systemic tumor. Gross total resection followed by multimodal therapy may provide for extended progression free and overall survival.

    Magnetic resonance imaging findings of a 38-year-old man with epithelioid sarcoma of the penis is presented. It started as a firm, painless and slowly growing nodule at the base of his penis 6 months previously which caused pain radiating to the testis during coitus. It has been well known that sarcomas may well mimic reactive processes. Initial presentation of epithelioid sarcoma may provoke considerable diagnostic difficulty, and its differentiation from benign lesions, such as Peyronie`s disease and chronic inflammation, may be a clinical problem. In our present report the MR findings are compared with those of the epithelioid sarcomas of various locations reported in the literature and differential diagnosis of the entity is discussed. To our knowledge, this is the first report regarding the MR findings of the epithelioid sarcoma of penis. (orig.) With 3 figs., 16 refs.

    Synovial sarcomas are rare soft tissue tumors which histopathologically can be divided into monophasic, biphasic and mixed variants. As part of a protocol for intra-arterial chemotherapy 12 patients with biopsy proven synovial sarcoma underwent angiography. The angiograms on these patients were reviewed to determine whether synovial sarcomas and their variants demonstrated a characteristic angiographic appearance. Synovial sarcomas appeared angiographically as soft tissue masses which showed a fine network of tumor vessels with an inhomogeneous capillary blush. Their degree of vascularity varied according to their histopathology. Monophasic synovial sarcomas demonstrated in general a higher degree of neovascularity than the biphasic form. This finding was also suggested by histopathologic analysis of the vessels in the tumor. Although angiography did not show a distinctive vascular pattern it may be useful to evaluate tumor size and vascularity. (orig.)

    Full Text Available Kaposi's sarcoma (KS became a critical health issue with the emergence of acquired immunodeficiency syndrome (AIDS in the 1980s. Four clinical-epidemiological forms of KS have been described: classical KS, endemic KS, iatrogenic KS, and AIDS-associated KS. In 1994, Kaposi's sarcoma-associated herpesvirus (KSHV or human herpesvirus type 8 was identified by Chang and colleagues, and has been detected worldwide at frequencies ranging from 80 to 100%. The aim of the present study was to evaluate the frequency of KSHV infection in KS lesions from HIV-positive and HIV-negative patients in Brazil, as well as to review the current knowledge about KS transmission and detection. For these purposes, DNA from 51 cases of KS was assessed by PCR: 20 (39.2% cases of classical KS, 29 (56.9% of AIDS-associated KS and 2 (3.9% of iatrogenic KS. Most patients were males (7.5:1, M/F, and mean age was 47.9 years (SD = ± 18.7 years. As expected, HIV-positive KS patients were younger than patients with classical KS. On the other hand, patients with AIDS-associated KS have early lesions (patch and plaque compared to classical KS patients (predominantly nodular lesions. This is assumed to be the result of the early diagnose of KS in the HIV-positive setting. KSHV infection was detected by PCR in almost all cases (48/51; 94.1%, irrespectively of the clinical-epidemiological form of KS. These results show that KSHV is associated with all forms of KS in Brazilian patients, a fact that supports the role of this virus in KS pathogenesis.

    Full Text Available Private insurance is associated with better outcomes in multiple common cancers. We hypothesized that insurance status would significantly impact outcomes in primary breast sarcoma (PBS due to the additional challenges of diagnosing and coordinating specialized care for a rare cancer. Using the National Cancer Database, we identified adult females diagnosed with PBS between 2004 and 2013. The influence of insurance status on overall survival (OS was evaluated using the Kaplan–Meier estimator with log-rank tests and Cox proportional hazard models. Among a cohort of 607 patients, 67 (11.0% had Medicaid, 217 (35.7% had Medicare, and 323 (53.2% had private insurance. Compared to privately insured patients, Medicaid patients were more likely to present with larger tumors and have their first surgical procedure further after diagnosis. Treatment was similar between patients with comparable disease stage. In multivariate analysis, Medicaid (hazard ratio (HR, 2.47; 95% confidence interval (CI, 1.62–3.77; p<0.001 and Medicare (HR, 1.68; 95% CI, 1.10–2.57; p=0.017 were independently associated with worse OS. Medicaid insurance coverage negatively impacted survival compared to private insurance more in breast sarcoma than in breast carcinoma (interaction p<0.001. In conclusion, patients with Medicaid insurance present with later stage disease and have worse overall survival than privately insured patients with PBS. Worse outcomes for Medicaid patients are exacerbated in this rare cancer.

    Undifferentiated embryonal sarcoma of the liver is a rare malignant mesenchymal tumour occurring mostly in children ages 6-10 years. The discrepancy between its solid appearance on US and cystic-like appearance on CT has been described. To study the imaging particularities and similarities among our cases of undifferentiated embryonal sarcoma and to report the errors in initial diagnoses. We conducted a retrospective study of 15 children with undifferentiated embryonal sarcoma diagnosed or referred to our hospital during 1997-2015 and analysed the clinical, biological and imaging data. We identified eight boys and seven girls ages 9 months to 14 years. Ten children presented with abdominal pain. Alpha-fetoprotein was slightly increased in one. Initial US and CT had been performed for all, while additional MRI had been done in two children. Initial CT demonstrated a hypoattenuated mass in all. Rupture was seen in five and intratumoural bleeding in seven children. Tumour volumes reduced during neoadjuvant chemotherapy in 10 children. Undifferentiated embryonal sarcoma might be suggested in a non-secreting unifocal tumour with well-defined borders, fluid-filled spaces on US, hypoattenuation and serpiginous vessels on CT, and if there are signs of internal bleeding or rupture on CT or MRI.

    The synovial sarcoma is one of the most common soft tissue sarcomas. MR is the technique of choice to determine to local extension of malignant soft tissue tumors. To assess the clinical and MR imaging parameters associated with synovial sarcomas that aid in establishing their diagnosis. We review the clinical findings and images of 23 histologically confirmed synovial sarcomas that were studied by MR. Synovial sarcomas usually develop in young adults as soft tissue tumors, preferentially in the deep tissues of an extremity in close proximity to a joint. They are characterized as having a lobulated contour and septa, frequently infiltrating neighboring tissues at some point, and are heterogeneous. The presence of hemorrhage, as well as infiltration of the fascia in subcutaneous tumors, suggests the diagnosis of synovial sarcoma. The development of perilesional edema is not uncommon. Although, logically, the clinical and radiological features of synovial sarcomas can overlap with those of other soft tissue tumors, the findings described here are fairly characteristic of these lesions: thus, when present, they should serve to orient the diagnostic process.

    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.

    Clear cell sarcoma (malignant melanoma of soft tissues) is a very rare soft tissue neoplasm. It generally arises in tendons and aponeuroses. Although metastasis of malignant melanoma to bone is not uncommon, primary clear cell sarcoma of bone is an extremely rare neoplasm. To our knowledge five cases have been reported in the English literature. We present a case of primary clear cell sarcoma of bone in a 28-year-old woman arising in the left ninth rib. We treated the patient with total excision of the mass and postoperative radiotherapy. The patient is alive and well without local recurrence or distant metastasis at 33 months after surgery.

    Ewing's sarcoma (ES) or primitive neuro-ectodermal tumor (PNET) typically occurs in long or flat bones, the chest wall, extra-skeletal soft tissue, and rarely in solid organs. Incidence of adrenal Ewing's sarcoma is very rare. Here we report a case of Ewing's sarcoma of the right adrenal gland in an 8-year-old girl who presented with an abdominal mass. The huge tumor was managed by preoperative neo-adjuvant chemotherapy followed by surgical resection. She died due to metastasis after five months of surgery.

    2011-01-01

    Ewing's sarcoma is a highly aggressive pediatric tumor of bone that usually contains the characteristic chromosomal translocation t(11;22)(q24;q12). This translocation encodes the oncogenic fusion protein EWS/FLI, which acts as an aberrant transcription factor to deregulate target genes necessary for oncogenesis. One key feature of oncogenic transformation is dysregulation of cell cycle control. It is therefore likely that EWS/FLI and other cooperating mutations in Ewing's sarcoma modulate the cell cycle to facilitate tumorigenesis. This paper will summarize current published data associated with deregulation of the cell cycle in Ewing's sarcoma and highlight important questions that remain to be answered. PMID:21052502

    Several maternal and birth characteristics have been reported to be associated with an increased risk of many childhood cancers. Our goal was to evaluate the risk of childhood embryonal solid tumors in relation to pre- and perinatal characteristics. A case-cohort study was performed using two population-based datasets, which were linked through R software. Tumors were classified as central nervous system (CNS) or non-CNS-embryonal (retinoblastoma, neuroblastoma, renal tumors, germ cell tumors, hepatoblastoma and soft tissue sarcoma). Children aged birth anomalies were independent risk factors. Among children diagnosed older than 24 months of age, cesarean section (CS) was a significant risk factor. Five-minute Apgar ≤8 was an independent risk factor for renal tumors. A decreasing risk with increasing birth order was observed for all tumor types except for retinoblastoma. Among children with neuroblastoma, the risk decreased with increasing birth order (OR = 0.82 (95% CI 0.67-1.01)). Children delivered by CS had a marginally significantly increased OR for all tumors except retinoblastoma. High maternal education level showed a significant increase in the odds for all tumors together, CNS tumors, and neuroblastoma. This evidence suggests that male gender, high maternal education level, and birth anomalies are risk factors for childhood tumors irrespective of the age at diagnosis. Cesarean section, birth order, and 5-minute Apgar score were risk factors for some tumor subtypes.

    Full Text Available Head and neck sarcomas are a rare and heterogeneous group of tumors that pose management challenges. We report our experience with these tumors. Forty consecutive patients treated for 44 head and neck sarcomas between 1997 and 2014 were culled from our prospectively maintained head and neck database. Five patients were excluded. The adult cohort consisted 29 (83% patients of a mean age of 57.7 years, with 33 sarcomas. The most common diagnoses were undifferentiated pleomorphic sarcoma (27% and chondroblastic osteosarcoma (21%. Clear surgical margins were achieved in 24/33 (73% lesions. Twenty-two patients received radiotherapy and/or chemotherapy. Fourteen patients developed local (n=6, regional (n=1 and distant (n=7 recurrence. The overall 5-year survival was 66% with a mean survival interval of 66.5 months. Recurrent sarcoma, close (<1mm or involved surgical margins and advanced age were associated with statistically significantly reduced survival. The pediatric cohort consisted 6 (17% patients, with a mean age of nine years. Five patients had primary embryonal rhabdomyosarcomas and one had chondroblastic osteosarcoma. Clear surgical margins were achieved in 5 (83% patients. All patients received adjuvant radiotherapy and/or chemotherapy. Mean survival interval was 102 months. Three patients developed local (n=1 or distant (n=2 recurrence. Twenty-three free and 8 pedicled flaps were performed in 25 patients. 11/39 (28% lesions in 11 patients developed a complication. In conclusion, head and neck sarcomas are best managed by a multidisciplinary team at a tertiary head and neck referral centre and resection with clear margins is vital for disease control.

    Epithelioid sarcoma of the penis is a slowly growing soft tissue neoplasm that rarely arises from the penis. The aim of this case is to describe this rare pathology and to underline the importance of differential diagnosis with benign diseases such as Peyronie's disease. We report the case of a 20-year-old man who referred the onset of a progressive left dorsolateral penile curvature (about 60°) started 3 years before. The patient was evaluated with two US examinations that revealed two sites of tunical thickening with normal hemodynamic evaluation. The physical examination demonstrated a dorsal fibrotic plaque of about 2.5 cm. A juvenile form of Peyronie's Disease was diagnosed, and the patient was scheduled for surgical treatment (plaque's incision/excision and grafting). Intraoperative appearance showed that the great part of the left cavernous body was substituted by a very tough tissue which deeply involved the erectile tissue; intraoperative frozen section was suspicious for mesenchymal epithelioid neoplasm. In order to obtain definitive histological analysis and collect proper informed consent, we preferred to proceed with our original project, applying a dual graft (buccal mucosa and allograft dermal matrix) to cover the wide excised area. The final histological report confirmed the diagnosis of epithelioid sarcoma. Postoperative CT and MRI, at 3 and 6 months from surgery, were negative for metastases. The patient underwent radical intervention after 6 months. Epithelioid sarcoma of the penis and Peyronie's Disease can present with similar clinical findings although they obviously entail a different clinical progress. Since the diagnosis of neoplasm can be established only by the pathologist on biopsy specimen, in cases of unusual clinical presentation of Peyronie's disease (especially in young men suffering from a fast-growing penile induration), an early histological assessment should be performed to avoid the possibility of misdiagnosis in case of this

    The outcome of localized Ewing's sarcoma has improved with multi-disciplinary approach. Survivals of Ewing's sarcoma from the Asian countries differed between centers. We retrospectively analyzed the records of newly diagnosed localized Ewing's sarcoma patients from 2002 to 2012. The patients were analyzed in three groups; Group 1(2002-2004) who received non-ifosfomide based regimens, Group 2(2005-2008) who received VDC/IE for 12 cycles, and Group 3(2009-2012), who received VDC/IE for 17 cycles. The groups were compared for their baseline characteristics, treatment protocol and outcome. Seventy three patients were included in the study. The median age of presentation was 15 years, with slight male predominance. Axial primary was seen in 62%. The median RFS of the three groups was 26.4, 31.4 and 36.8 months respectively ( P = 0.0018). The median OS was 27.9, 35 and 43 months respectively ( P = 0.0007). At a median follow-up of 35 months, the 3 year RFS and OS for the three treatment groups were 17%, 31%, 60% and 35%, 45% and 70% respectively. Larger tumor size, axial primary, high LDH were associated with poorer survival. Radiotherapy was associated with inferior local control and survival. We found that the survival of our ESFT patients improved over time with intensified multiagent chemotherapy and with lesser time to local therapy. But the results were still inferior to those reported in literature. We had majority of patients presenting in axial site and radiotherapy as the predominant mode of local control. The outcome may further improve with surgery as local control procedure.

    Moriz Kaposi was the first who, in 1872, described five patients presenting with `sarcoma idiopathicum multiple hemorrhagicum`. In 1912 Sternberg termed this disease Kaposi`s sarcoma. Since then various forms of this rare disease have been observed. In 1914 Hallenberg described the first cases of African or endemic Kaposi`s sarcoma. In the 1960`s the first reports discussing Kaposi`s sarcoma following organ transplantation and immunosuppressive therapy were published. After 1981, the epidemic form associated with the acquired immunodeficiency syndrome (AIDS) was described. All these forms, their history, treatment methods and the role of radiation therapy in the management of this rare malignancy are discussed, and the literature is reviewed. (authors)

Since these tumors were often visible to the public, Kaposi’s sarcoma quickly became a stigmatizing marker for those infected, and predicted the high mortality risk from comorbid opportunistic infections. English language films released from 1985-2008 are analyzed for their depictions of Kaposi’s sarcoma, and the role(s it played in these films. With the advent of highly active antiretroviral therapy for those with HIV infection, Kaposi’s sarcoma has once again become relatively rare.

    Objective: To determine CT and MRI imaging features in patients with a diagnosis of retroperitoneal lipo sarcoma. Material and Methods: Retrospective analysis of 6 cases, studied with CT and/or MRI in patients with retroperitoneal lipo sarcoma during the last 4 years at our institution. We analyzed symptoms, treatment and prognosis with special focus on the CT and MRI findings and their histological correlation. Results: the most frequent histological subtype in our group of patients was the pleomorphic lipo sarcoma (n=3). In the others cases, 2 were well differentiated and one was round-cell type. Retroperitoneal lipo sarcoma, especially the well differentiated, presented certain imaging patterns which allowed to suspect the subtype of tumor. Recurrences occurred in 50% (n=3). Mortality rate was 33.4% (n=2) (follow-up, 16 months). Conclusion: Both CT and MRI are methods which aid in the detection of this rare disorder, as well as in its diagnosis and follow-up. (author)

    Sarcomas are a heterogeneous group of tumors. Their diagnosis is based on morphology and immunohistochemical profile, with categories of tumors according to the type of tissue that they resemble. Nevertheless, for several tumors, cellular origin is unknown. Molecular analysis performed in recent years allowed, combining histophenotype and genomics, better classifying such sarcomas, individualizing new entities and grouping some tumors. Simple and recurrent genetic alterations, such as translocation, mutation, amplification, can be identified in one of two sarcomas and appear as new diagnostic markers. Their identification in specialized laboratories in molecular pathology of sarcomas is often useful and sometimes necessary for a good diagnosis, leading to a heavy and multidisciplinary multi-step treatment.

    Full Text Available CONTEXT: Ewing's sarcoma is a rare neoplasm, which usually arises in long bones of the limbs and in flat bones of the pelvis, with the involvement of head and neck bones being very unusual. CASE REPORT: a case of Ewing's sarcoma occurring in the mandible of a 35-year-old female. Pain and swelling of the tumor were the main complaints. The early hypothesis was an undifferentiated malignant neoplasm, possibly a sarcoma. The CT scan depicted an expansive lesion, encapsulated, with septa and characteristics of soft tissue, involving the left side of the mandible and extending to the surrounding tissues. The patient underwent surgical excision of the lesion, the definitive diagnosis of Ewing's sarcoma was established, and the patient commenced on radiotherapy.

    Ewing's sarcoma is a round cell neoplasm derived from neural crest cells that is part of the primitive neuroectodermal tumor (PNET) family. It is a rare, aggressive malignancy that affects young people, most commonly in the second decade of life. The treatment of localized disease has improved greatly over the past four decades, but the prognosis for metastatic disease remains poor. Cardiac metastases of Ewing's sarcoma are exceedingly rare, with only a few reported cases. This...

    2012-01-01

    Soft tissue sarcomas are an uncommon and diverse group of more than 50 mesenchymal malignancies. The pathogenesis of many of these is poorly understood, but others have begun to reveal the secrets of their inner workings. With considerable effort over recent years, soft tissue sarcomas have increasingly been classified on the basis of underlying molecular alterations. In turn, this has allowed the development and application of targeted agents in several specific, molecularly defined, sarcoma subtypes. This review will focus the rationale for targeted therapy in sarcoma, with emphasis on the relevance of specific molecular factors and pathways in both translocation-associated sarcomas and in genetically complex tumors. In addition, we will address some of the early successes in sarcoma targeted therapy as well as a few challenges and disappointments in this field. Finally we will discuss several possible opportunities represented by poorly understood, but potentially promising new therapeutic targets, as well as several novel biologic agents currently in preclinical and early phase I/II trials. This will provide the reader with context for understanding the current state this field and a sense of where it may be headed in the coming years. PMID:22498582

    Context. - The National French Federation of Comprehensive Cancer Centres (FNCLCC) initiated the update of clinical practice guideline for the management of patients with soft tissue sarcoma in collaboration with the French Sarcoma Group (GSF-GETO), specialists from French public universities, general hospitals and private clinics and with the French National Cancer Institute. This work is based on the methodology developed in the 'Standards, Options and Recommendations' (SOR) project. Objectives - To update SOR guidelines for the management of patients with oft tissue sarcoma previously validated in 1995. Methods. -The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guidelines have been developed, they are reviewed by independent reviewers. Results. - This article presents the updated recommendations for radiotherapeutic management. The main recommendations are: 1) irradiation before or after surgical treatment is the standard for soft tissue sarcoma of the extremity and uterine sarcoma; 2) no systematic irradiation should be done in case of retroperitoneal sarcoma.

    Lung cancer during pregnancy is a rare situation which is being increasingly reported during the past two decades due to a rising trend of cigarette smoking among young women and the tendency to delay pregnancy to a later age in life. We describe the case of a 32-year-old woman with primary pulmonary sarcoma, diagnosed at 31st week of pregnancy. X-ray chest and thoracic magnetic resonance imaging revealed a 9 x 6 cm mass in the left mediastinum, with tracheal shift, and pleural effusion. Biopsy performed during broncoscopy, was reported as mesenchymal tumour. She delivered a baby by Caesarean section at the 32nd week of gestation due to the development of superior vena cava syndrome. A skin biopsy taken 3 weeks later from the nodular lesion at the periumblical region was reported as a tumour metastasis. She received radiotherapy for 10 days, but died in the intensive care unit. Malignancies, even those as uncommon as a pulmonary sarcoma, should be considered in the differential diagnosis of pleural effusion during pregnancy.

    Background: Some former retrospective studies have suggested that patients with Ewing's sarcoma might have a very high risk for developing secondary sarcomas if treated with radiotherapy. We have evaluated the risk of second malignancies (SM) in patients treated in the German Cooperative Ewing's Sarcoma Studies CESS 81 and CESS 86. Materials and methods: From January 1981 through June 1991, a total number of 674 patients was registered in the two multicentric Ewing's sarcoma trials CESS 81 (1981 through 1985) and CESS 86 (1986 through June 1991). The systemic treatment consisted in both studies of a four-drug-chemotherapy (VACA= vincristine, actinomycin D, cyclophosphamide and adriamycin; or VAIA= vincristine, actinomycin D, ifosfamide and adriamycin) and a total number of four courses, each lasting nine weeks, was recommended by the protocol. Local therapy was either complete surgery or surgery plus postoperative radiotherapy with 36-46Gy or definitive radiotherapy with 46 to 60Gy. The median follow-up at the time of this analysis was 7 years, the maximum follow-up 16 years. Results: Eight patients developed a SM, 4 were acute myelogenic leucemias, three sarcomas and one benign neurinoma. One of the sarcomas was considered as radiation-induced because of its location in the former radiation field. The interval between diagnosis of Ewing's sarcoma and the diagnosis of the SM was 17 to 78 months for the four AMLs and 82 to 136 months for the three sarcomas. All solid second tumors occurred in irradiated patients. The cumulative risk of a SM is given in table 1. Three patients (all with AML) died of their SM, the other five were salvage by subsequent treatment and are in clinical remission with a median follow-up of 1 to 10 years. Conclusions: The risk of leukemia after treatment for Ewing's sarcoma is probably low in the range of 1-2% or less and accounts for about 1% of all deaths. There was no risk of solid tumors in surgically treated patients. Irradiated

    The aetiology of childhood cancer is poorly understood. Both genetic and environmental factors are likely to be involved. The presence of spatial clustering is indicative of a very localized environmental component to aetiology. Spatial clustering is present when there are a small number of areas with greatly increased incidence or a large number of areas with moderately increased incidence. To determine whether localized environmental factors may play a part in childhood cancer aetiology, we analyzed for spatial clustering using a large set of national population-based data from Great Britain diagnosed 1969-1993. The Potthoff-Whittinghill method was used to test for extra-Poisson variation (EPV). Thirty-two thousand three hundred and twenty-three cases were allocated to 10,444 wards using diagnosis addresses. Analyses showed statistically significant evidence of clustering for acute lymphoblastic leukaemia (ALL) over the whole age range (estimate of EPV = 0.05, p = 0.002) and for ages 1-4 years (estimate of EPV = 0.03, p = 0.015). Soft-tissue sarcoma (estimate of EPV = 0.03, p = 0.04) and Wilms tumours (estimate of EPV = 0.04, p = 0.007) also showed significant clustering. Clustering tended to persist across different time periods for cases of ALL (estimate of between-time period EPV = 0.04, p =0.003). In conclusion, we observed low level spatial clustering that is attributable to a limited number of cases. This suggests that environmental factors, which in some locations display localized clustering, may be important aetiological agents in these diseases. For ALL and soft tissue sarcoma, but not Wilms tumour, common infectious agents may be likely candidates.

    Significant progress in the treatment of soft tissue sarcoma (STS), both primary tumor and local recurrences/metastatic disease, has been achieved in recent years. Surgery is essential modality, but the use of combined treatment (standard combination of surgery with adjuvant radiotherapy, chemotherapy in selected cases and perioperative rehabilitation) in highly-experienced centers increased possibility of cure and limitations of extent of local surgery. Current combined therapy together with the use of reconstructive methods allows for limb-sparing surgery in majority of soft tissue sarcoma patients (amputation in 10% of cases as compared to approximately 50% in the 1960 - 70s). The slow, but constant, increase of rate of soft tissue sarcoma patients with long-term survival has been observed. Contemporary 5-year overall survival rate in patients with extremity soft tissue sarcomas is 55 -78%. In case of diagnosis of metastatic disease the prognosis is still poor (survival of approximately 1 year). Good results of local therapy may be expected only after planned (e.g., after preoperative biopsy - tru - cut or incisional) radical surgical excision of primary tumor with pathologically negative margins (R0 resection). Following appropriate diagnostic check-up, adjuvant radiotherapy is necessary in the majority of patients treated with radical surgery need, as well as long-term rehabilitation and follow-up examinations in treating center are needed for at least 5 years. The progress is due to the introduction of targeted therapy acting on molecular or genetic cellular disturbances detected during studies on etiopathogenetic mechanisms of sarcoma subtypes. In view of rarity of sarcomas and necessity of multidisciplinary therapy, the crucial issue is that management of these tumors should be hold in experienced oncological sarcoma centers. (authors)

    Desmoid tumors are rare benign monoclonal fibroblastic tumors. Their aggressiveness is local with no potential for metastasis or dedifferentiation. Here we report on a 61-year-old patient who presented a locally advanced breast desmoid tumor diagnosed 20 years after post-operative radiotherapy for breast carcinoma. After 2 years of medical treatment, a high-grade undifferentiated pleomorphic soft tissue sarcoma arose within the desmoid tumor. Despite extensive surgery removing both tumors, the patient showed locoregional relapse by the sarcoma, followed by multimetastatic progression, then death 25 months after the surgery. The arising of a soft tissue sarcoma in a desmoid tumor is an exceptional event since our case is the fourth one reported so far in literature. It reinforces the need for timely and accurate diagnosis when a new mass develops in the region of a preexisting desmoid tumor, and more generally when a desmoid tumor modifies its clinical or radiological aspect.

    Epithelioid sarcoma is a heterogeneous tumor with 2 subtypes, classic and proximal. The proximal variant is more aggressive and occurs in proximal location in young adults. We present a proximal epithelioid sarcoma in the leg of an 8 year old girl with rhabdoid morphology and scattered osteoclastic giant cells. Nuclear INI-1 was retained. Despite wide local excision, local recurrence occurred at 8 months. Following re-excision, she developed a chest wall metastasis after 9 months. Epithelioid sarcoma, proximal type with osteoclastic giant cells in the pediatric age group has not been reported previously and should be considered in the differential diagnoses of tumors with epithelioid cell morphology and scattered osteoclastic giant cells. Retained INI expression helped to differentiate this tumor from malignant rhabdoid tumor.

    Full Text Available A 49-year-old patient presented with a right ovarian mass, which, on microscopy, showed to consist of haphazardly oriented large pleomorphic cells with abundant cytoplasm. Periodic acid Schiff stain was positive but negative with diastase digestion. Immunohistochemical staining with Desmin showed intense cytoplasmic positivity in almost all the cells. Cytokeratin, epithelial membrane antigen, smooth muscle actin, HMB-45, S-100 and neurone-specific enolase were negative. Immunohistochemical staining with Myogenin showed intense nuclear positivity. There was no other primary tumor on extensive search. A diagnosis of primary sarcoma of the ovary with rhabdomyosarcomatous differentiation was made. The incidence of similar tumors of the ovary are low and therefore little data are available on this uniformly lethal tumor. Thus, such cases need to be reported to pool experience so that the tumor can be diagnosed early.

    Objective: To explore the clinical and histopathological features of primary, intimal sarcoma of the pulmonary artery. Methods: One case of primary intimal sarcoma of the pulmonary artery diagnosed in our hospital and 20 cases published openly in China were analysed retrospectively. Results: The clinical presentation of primary intimal sarcoma of the pulmonary artery was progressive dyspnea, cough, chest pain, syncope, bloody phlegm, fever and fatigue. From the radiological finding, its signs were of pulmonary, artery dilation, reduced pulmonary vasculature and cardiomegaly, soft tissue mass near the right ventricle outflow tract. Histological examination of intimal sarcoma of the pulmonary artery revealed a poorly differentiated mesenchymal tumor of fibroblastic or myofibroblastic differentiation, consisting of mildly atypical spindle cells with atypia, mitosis, and nuclear polymorphism. Immunohistochemical analysis showed positive staining with antibodies against vimentin, alpha-smooth muscle actin, while negative for desmin. Conclusion: Primary, intimal sarcoma of the pulmonary artery has atypical clinical and radiological manifestation with poor prognosis, its definite diagnosis depends on histopathology. (authors)

  13. Olaratumab for advanced soft tissue sarcoma.

    2017-07-01

    Olaratumab is a humanized IgG1 monoclonal antibody that blocks the platelet-derived growth factor receptor alpha (PDGFRα). Its antagonistic behavior inhibits the receptor's tyrosine kinase activity, thereby, turning off the downstream signaling cascades responsible for soft tissue sarcoma tumorigenesis. In October 2016, olaratumab received Food and Drug Administration (FDA) approval for its use in combination with doxorubicin for treatment of advanced soft tissue sarcoma. Areas covered: This drug profile takes a comprehensive look at the clinical studies leading to FDA approval of olaratumab as well as its safety and efficacy as a front-line treatment option for sarcoma patients. The literature search was primarily conducted using PubMed. Expert commentary: The combination of olaratumab plus doxorubicin has provided a new front-line therapeutic option for soft tissue sarcoma patients. An open-label phase Ib and randomized phase II trial in patients with advanced soft tissue sarcoma demonstrated that the addition of olaratumab to doxorubicin prolonged progression-free survival by 2.5 months and overall survival by 11.8 months when compared to doxorubicin alone. Of importance, this clinically meaningful increase in overall survival did not come at the expense of a significantly greater number of toxicities. A phase III confirmatory trial (ClinicalTrials.gov Identifier NCT02451943) will be completed in 2020.

    Full Text Available Endometrial stromal tumors are rare uterine tumors (<1%. Four main categories include endometrial stromal nodule, low-grade endometrial stromal sarcoma (LG-ESS, high-grade endometrial stromal sarcoma (HG-ESS, and uterine undifferentiated sarcoma (UUS. This review is a series of articles discussing the uterine sarcomas. LG-ESS, a hormone-dependent tumor harboring chromosomal rearrangement, is an indolent tumor with a favorable prognosis, but characterized by late recurrences even in patients with Stage I disease, suggesting the requirement of a long-term follow-up. Patients with HG-ESS, based on the identification of YWHAE-NUTM2A/B (YWHAE-FAM22A/B gene fusion, typically present with advanced stage diseases and frequently have recurrences, usually within a few years after initial surgery. UUS is, a high-grade sarcoma, extremely rare, lacking a specific line of differentiation, which is a diagnosis of exclusion (the wastebasket category, which fails to fulfill the morphological and immunohistochemical criteria of translocation-positive ESS. Surgery is the main strategy in the management of uterine sarcoma. Due to rarity, complex biological characteristics, and unknown etiology and risk factors of uterine sarcomas, the role of adjuvant therapy is not clear. Only LG-ESS might respond to progestins or aromatase inhibitors.

  15. Targeted Therapy of Ewing's Sarcoma

    Directory of Open Access Journals (Sweden)

    Vivek Subbiah

    2011-01-01

    Full Text Available Refractory and/or recurrent Ewing's sarcoma (EWS remains a clinical challenge because the disease's resistance to therapy makes it difficult to achieve durable results with standard treatments that include chemotherapy, radiation, and surgery. Recently, insulin-like-growth-factor-1-receptor (IGF1R antibodies have been shown to have a modest single-agent activity in EWS. Patient selection using biomarkers and understanding response and resistance mechanisms in relation to IGF1R and mammalian target of rapamycin pathways are areas of active research. Since EWS has a unique tumor-specific EWS-FLI1 t(11;22 translocation and oncogenic fusion protein, inhibition of EWS-FLI1 transcription, translation, and/or protein function may be key to eradicating EWS at the stem-cell level. Recently, a small molecule that blocks the protein-protein interaction of EWS-FLI1 with RNA helicase A has been shown in preclinical models to inhibit EWS growth. The successful application of this first-in-class protein-protein inhibitor in the clinic could become a model system for translocation-associated cancers such as EWS.

    Within soft-tissue sarcoma, primitive neuroectodermal tumors have been shown to cover a wide spectrum of small round cell sarcomas, including Ewings sarcomas (Es) and primitive neuroectodermal tumors (PET). The role of the stem cell factor/kit pathway has been investigated in different human tumors especially in chronic metallically leukemia and gastrointestinal stromal tumor and an autocrine loop has been assumed in small cell lung carcinoma, and recently in Es and PET. Our aim is to investigate the c-kit expression in Es and PET and also to assessed if c-kit has any role in disease process. We thoroughly searched the archives of the Department of Pathology, Faculty of Medicine, Cukurova University Turkey, between 2000 and 2004; and found 14 ES and 14 PNET paraffin embedded tissues. We carried out the detection of the c-kit expression by immunohistochemical staining. The patients median age was 23.7 +/-14.6 (12 male and 16 female). Five were diagnosed as metastatic disease whereas 23 were diagnosed as non-metastatic disease at admission. The mean follow up period was 38.9 +/- 22.3 months. The main localization of the disease was lower extremity (32.1%), and others were as follows: head and neck 25%, thorax and abdomen 14.3%, pelvic and upper extremity 7.1% (11 were localized skeletal and 17 were extraskeletal). According to treatment modalities, 10 were treated with surgery alone, 11 with surgery and chemotherapy, and 7 with surgery, radiation therapy and also with chemotherapy. The primary tumor was lower than 5 cm in its dimension in 21 patients. While in 5 patients, tumor was more than 5 cm but did not exceed 10 cm, it was >10 cm in 2 patients. The c-kit expression was positive in 7 patients both cytoplasmic and membranously, whereas 8 patients were positive cytoplasmically. In 5 PNET patients, c-kit expression were stained immunohistochemically in over 50% and in 3 of ES patients. There was no significant correlation between c-kit expression and gender

    Seven patients received radiation for malignancies, and two received for benign tumors. The latency period from radiation to symptom ranged from two years to 36 years (mean 17.2 years). Post-radiation soft tissue sarcomas (PRS) comprised six cases of malignant fibrous histiocytomas, two leiomyosarcomas, and one angiosarcoma. The five-year survival of PRS was 16.7% showing a worse prognosis than spontaneously occurring soft tissue sarcomas. Seven PRS occurred superficially, and two were deeply located. Four cases occurring in the superficial tissues had histories of radiation-induced dermatitis. The radiation-induced dermatitis was suggested to be a risk factor for development of PRS. (author)

    SUMMARY Soft tissue sarcomas are rare neoplasms, with approximately 9,000 new cases in the United States every year. Unfortunately, there is little progress in the treatment of metastatic soft tissue sarcomas in the past two decades beyond the standard approaches of surgery, chemotherapy, and radiation. Immunotherapy is a modality complementary to conventional therapy,. It is appealing because functional anti-tumor activity could affect both local-regional and systemic disease and act over a prolonged period of time. In this report, we review immunotherapeutic investigative strategies being developed, including several tumor vaccine, antigen vaccine, and dendritic cell vaccine strategies. PMID:22401634

    INTRODUCTION: Clear cell sarcoma (CCS) is a rare tumour of the soft tissue often misdiagnosed, as it shares characteristics with malignant melanoma (MM). Previously, CCS has been characterised, as malignant melanoma of the soft tissue, contemporary immunohistochemical techniques, however, have made...... this designation obsolete. The true incidence remains unknown, but CCS is believed to represent less than one percent of all sarcomas.

    A retrospective review of 33 cases of soft tissue sarcoma of the extremity presenting over a 10 year period was undertaken. The history, patterns of referral, diagnostic investigations, procedures undertaken and outcomes were studied. We found there was a frequent delay in diagnosis and sometimes misinterpretation of biopsy specimens. Patients were seen by a variety of specialists from disciplines such as general surgery, plastic surgery, orthopaedic surgery and rheumatology. Considerable progress has been made in the treatment of soft tissue sarcomas, often allowing local control of the tumour without amputation. We believe there should be early referral of patients having these tumours to a centre where a combined multidisciplinary approach can be undertaken.

    Full Text Available Ewing sarcoma was named after James R. Ewing, an eminent American pathologist at Cornell who described the first cases in 1921. Although he is best remembered for this singular achievement, Ewing's contributions to the study of cancer were far more profound and influential. He essentially launched oncology as a discipline with the publication of his seminal textbook and founded the major American cancer societies that exist today. His vision of comprehensive cancer centers still drives our research infrastructure. Since his initial report, these organizations have helped us achieve numerous milestones in understanding and treating patients with Ewing sarcoma.

    An adult female captive pygmy hippopotamus (Choeropsis liberiensis) was diagnosed with an oral anaplastic sarcoma. The tumor was surgically debulked and intralesional chemotherapy with mitomycin C (0.4 mg/cm 3 of tumor) and cisplatin (1 mg/cm 3 of tumor) was administered. Chemotherapeutic treatment proved difficult due to the risks of repeated anesthetics and unknown drug efficacies. Marked proliferation of the mass was observed during estrus, and chemotherapy was repeated as an experimental treatment to slow tumor progression in order for the animal to remain in the species breeding program. Tumor proliferation was detected during the first trimester of pregnancy; however, in the lactation period, the mass became quiescent. No adverse reactions to chemotherapeutic drugs were observed and the animal continues to be monitored for tumor progression. This is the first report of an anaplastic sarcoma and of chemotherapy use in a pygmy hippopotamus and it highlights logistical considerations for treating neoplasia in this species.

    Cancer in children is increasingly recognized as a major and growing health problem in different developed and developing countries. In Yemen, it is still difficult to know the extent of cancer and its determinants among children. This study was conducted to determine the magnitude of childhood cancer in Aden and provide the preliminary baseline data by age and sex. Basic epidemiologic data was retrieved from all paediatric cancer Yemen, from 1997 to 2006. The results showed a total of 483 childhood cancers 5 years. An interesting comparison was the preponderance of non-Hodgkins's lymphoma over Hodgkin's disease (1.6:1) stronger in female (3:1) than male (1.25:1). Medulloblastoma was the most common CNS tumour followed by astrocytoma, an infrequent finding in childhood cancer. Osteosarcoma was the most frequent bone tumour (male:female ratio of 1.8:1). A female preponderance was noticed in chondrosarcoma that was not yet documented. The blastoma group was common in younger age group. Retinoblastoma and nephroblastoma predominated in female while neuroblastoma, hepatoblastoma and soft tissue sarcomas in male. It is concluded that there is a lower frequency of childhood cancer in Aden when compared with developed countries. It may explained by the fact that a large number of childhood cancers remain undiagnosed due to limitations of diagnostic facilities or under registration. Central paediatric hospitals should be provided with essential diagnostic and therapeutic services that should be freely available to all children with cancer. Copyright © 2013 Elsevier Ltd.

    One hundred forty-three patients who received radiation therapy for childhood tumors, and survived to the age of skeletal maturity, were studied by retrospective review of oncology records and roentgenograms. Diagnoses for the patients were the following: Hodgkin's lymphoma (44), Wilms's tumor (30), acute lymphocytic leukemia (26), non-Hodgkin's lymphoma (18), Ewing's sarcoma (nine), rhabdomyosarcoma (six), neuroblastoma (six), and others (four). Age at the follow-up examination averaged 18 years (range, 14-28 years). Average length of follow-up study was 9.9 years (range, two to 18 years). Asymmetry of the chest and ribs was seen in 51 (36%) of these children. Fifty (35%) had scoliosis; 14 had kyphosis. In two children, the scoliosis was treated with a brace, while one developed significant kyphosing scoliosis after laminectomy and had spinal fusion. Twenty-three (16%) patients complained of significant pain at the radiation sites. Twelve of the patients developed leg-length inequality; eight of those were symptomatic. Three patients developed second primary tumors. Currently, the incidence of significant skeletal sequelae is lower and the manifestations are less severe than reported in the years from 1940 to 1970. The reduction in skeletal complications may be attributed to shielding of growth centers, symmetric field selection, decreased total radiation doses, and sequence changes in chemotherapy

    The X-linked BCL-6 co-repressor (BCOR) gene encodes a key constituent of a variant polycomb repressive complex (PRC) that is mutated or translocated in human cancers. Here we report on the identification of somatic internal tandem duplications (ITDs) clustering in the C terminus of BCOR in 23 of 27 (85%) pediatric clear cell sarcomas of the kidney (CCSK) from two independent cohorts. We profile CCSK tumours using a combination of whole-exome, transcriptome and targeted sequencing. Identical ITD mutations are found in primary and relapsed tumour pairs but not in adjacent normal kidney or blood. Mutant BCOR transcripts and proteins are markedly upregulated in ITD-positive tumours. Transcriptome analysis of ITD-positive CCSKs reveals enrichment for PRC2-regulated genes and similarity to undifferentiated sarcomas harbouring BCOR–CCNB3 fusions. The discovery of recurrent BCOR ITDs defines a major oncogenic event in this childhood sarcoma with significant implications for diagnostic and therapeutic approaches to this tumour. PMID:26573325

    Sarcomas are a group of cancers that arise from transformed cells of mesenchymal origin. They can be classified into over 50 subtypes, accounting for approximately 1% of adult and 15% of pediatric cancers. Wide surgical resection, radiotherapy, and chemotherapy are the most common treatments for the majority of sarcomas. Among these therapies, chemotherapy can palliate symptoms and prolong life for some sarcoma patients. However, sarcoma cells can have intrinsic or acquired resistance after treatment with chemotherapeutics drugs, leading to the development of multidrug resistance (MDR). MDR attenuates the efficacy of anticancer drugs and results in treatment failure for sarcomas. Therefore, overcoming MDR is an unmet need for sarcoma therapy. Certain protein kinases demonstrate aberrant expression and/or activity in sarcoma cells, which have been found to be involved in the regulation of sarcoma cell progression, such as cell cycle, apoptosis, and survival. Inhibiting these protein kinases may not only decrease the proliferation and growth of sarcoma cells, but also reverse their resistance to chemotherapeutic drugs to subsequently reduce the doses of anticancer drugs and decrease drug side-effects. The discovery of novel strategies targeting protein kinases opens a door to a new area of sarcoma research and provides insight into the mechanisms of MDR in chemotherapy. This review will focus on the recent studies in targeting protein kinase to reverse chemotherapeutic drug resistance in sarcoma. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Because of new therapeutic trends of multi-modality and the importance of late effects, we have updated our series of radiation induced bone sarcomas seen at Memorial Sloan-Kettering Cancer Center over the past four decades. A total of 37 cases of bone sarcoma arising from normal bone in the irradiated field was analyzed. The median for latent period from irradiation to diagnosis of bone sarcoma was 11 years with a minimum latent period of four years. The median radiation dose for the bone sarcoma was 6000 rad in 6 weeks with a minimum total radiation dose of 3000 rad in 3 weeks. We have found nine patients who developed bone sarcomas in the radiation field after successful treatment of Hodgkin's disease. Criteria for radiation induced bone sarcomas and the magnitude of the risk of bone sarcomas are briefly discussed

    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 Kaposi 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). Thallium scintigraphy is a potentially useful procedure for detecting extracutaneous Kaposi sarcoma in AIDS patients

    Autophagy is a constitutively active, evolutionary conserved, catabolic process for maintaining homeostasis in cellular stress responses and cell survival. Although its mechanism has not been fully illustrated, recent work on autophagy in various types of sarcomas has demonstrated that autophagy exerts an important role in sarcoma cell growth and proliferation, in pro-survival response to therapies and stresses, and in therapeutic resistance of sarcoma. Thus, the autophagic process is being seen as a possibly novel therapeutic target of sarcoma. Additionally, some co-regulators of autophagy have also been investigated as promising biomarkers for the diagnosis and prognosis of sarcoma. In this review, we summarize contemporary advances in the role of autophagy in sarcoma and discuss the potential of autophagy as a new target for sarcoma treatment. Copyright © 2017 Elsevier B.V.

    From the records of Memorial Hospital of the past 50 years, 47 cases with an established diagnosis of radiation-induced sarcoma were identified and divided into two groups: the first included 20 cases of soft-tissue sarcoma arising from irradiated tissues, and the second comprised 27 cases of bone sarcoma arising from normal bones in the irradiated field. Medians for the latent periods from irradiation to diagnosis of bone and soft-tissue sarcoma were 11 and 12, years, respectively. In bone sarcomas, the latent period was longer after larger radiation doses and children appeared to be more susceptible to cancer induction than adults. Criteria for establishing the diagnosis of radiation-induced sarcoma and the magnitude of the risk of bone sarcoma are discussed

    Purpose - We wanted to examine the potential of the Scandinavian Sarcoma Group (SSG) Central Register, and evaluate referral and treatment practice for soft-tissue sarcomas in the extremities and trunk wall (STS) in the Nordic countries. Background - Based on incidence rates from the literature, 8,150 (7,000-9,300) cases of STS of the extremity and trunk wall should have been diagnosed in Norway, Finland, Iceland, and Sweden from 1987 through 2011. The SSG Register has 6,027 cases registered from this period, with 5,837 having complete registration of key variables. 10 centers have been reporting to the Register. The 5 centers that consistently report treat approximately 90% of the cases in their respective regions. The remaining centers have reported all the patients who were treated during certain time periods, but not for the entire 25-year period. Results - 59% of patients were referred to a sarcoma center untouched, i.e. before any attempt at open biopsy. There was an improvement from 52% during the first 5 years to 70% during the last 5 years. 50% had wide or better margins at surgery. Wide margins are now achieved less often than 20 years ago, in parallel with an increase in the use of radiotherapy. For the centers that consistently report, 97% of surviving patients are followed for more than 4 years. Metastasis-free survival (MFS) increased from 67% to 73% during the 25-year period. Interpretation - The Register is considered to be representative of extremity and trunk wall sarcoma disease in the population of Scandinavia, treated at the reporting centers. There were no clinically significant differences in treatment results at these centers.

    Full Text Available Outcomes for patients with metastatic and recurrent Ewing sarcoma remain poor and a better understanding of the biology of this malignancy is critical to the development of prognostic biomarkers and novel therapies. Therefore, the Children’s Oncology Group (COG has created tissue banking protocols designed to collect high quality clinically annotated tumor specimens that can be distributed to researchers to perform basic science and correlative investigation. Data from the COG Ewing sarcoma tissue banking protocols AEWS02B1 and its successor study AEWS07B1 were reviewed in this study. 635 patients were enrolled on AEWS02B1 and 396 patients have had tissue submitted to AEWS07B1. The average age of participation was 13.2 years. 86% were less than 19 years old and only 6% were greater than 21 years of age at diagnosis. When compared to SEER data, approximately 18% of all cases and only 8% of all patients >20 years old diagnosed with Ewing sarcoma annually in the United States have had tumor banked. The majority of participants submitted formalin fixed paraffin embedded primary tumor and blood samples. In total, fresh frozen tissue was submitted for only 29% of cases. Only 7 metastatic tumor samples have been collected. Although the COG has been successful in collecting tumor samples from patients newly diagnosed with Ewing sarcoma, fresh frozen tumor specimens from primary and metastatic disease are critically needed, especially from young adult patients, in order to conduct high quality basic science and translational research investigation with a goal of developing better treatments.

    Outcomes for patients with metastatic and recurrent Ewing sarcoma remain poor and a better understanding of the biology of this malignancy is critical to the development of prognostic biomarkers and novel therapies. Therefore, the Children’s Oncology Group (COG) has created tissue banking protocols designed to collect high quality, clinically annotated, tumor specimens that can be distributed to researchers to perform basic science and correlative investigation. Data from the COG Ewing sarcoma tissue banking protocols AEWS02B1 and its successor study AEWS07B1 were reviewed in this study. Six-hundred and thirty five patients were enrolled on AEWS02B1 and 396 patients have had tissue submitted to AEWS07B1. The average age of participation was 13.2 years. About 86% were less than 19 years old and only 6% were greater than 21 years of age at diagnosis. When compared to SEER data, approximately 18% of all cases and only 8% of all patients >20 years old diagnosed with Ewing sarcoma annually in the United States have had tumor banked. The majority of participants submitted formalin fixed, paraffin embedded, primary tumor and blood samples. In total, fresh frozen tissue was submitted for only 29% of cases.

  19. Radiation induced expression of survivin in Ewing sarcoma cell-lines

    2009-01-01

    Full text: Introduction: Survivin belongs to the Inhibitor of Apoptosis Protein Family (IAP), is a protein of 16.5 kD and active as a homodimer. It is overexpressed in nearly all human tumors and has a vital function in cell division and apoptotic processes. Beside its role as a relevant prognostic and predictive factor it was described to be a molecular target to improve effectiveness of radiotherapy. We investigated the radiation induced survivin expression in Ewing sarcoma cell-lines. Methods: Ewing sarcoma cells were either irradiated with 10 Gy X-ray and harvested at different time points (0, 2, 4, 6, 10 and 24 h) or irradiated with different doses (0, 2, 5 and 10 Gy) and harvested 24 h later. Protein and mRNA expression was analysed by Westernblot or Real-Time PCR. Results: Directly after irradiation with 10 Gy X-ray survivin mRNA expression was increased in relation to the reference GAPDH. Protein expression was increased in a time dependent manner and reached a maximum after 24h. Three of four investigated cell-lines showed a significant dose dependent increase of survivin protein concentration 24h after irradiation. The same three cell-lines showed a LD50 of >30 Gy. The line with the lowest dose dependent survivin induction was investigated to be most radiosensitive (LD50 = 24 Gy). Discussion: Ewing sarcoma is a childhood tumor with relatively poor prognosis. This tumor often shows significant therapeutic resistance to chemo- and/or radiotherapy. It would be of high interest to find new therapeutic approaches for its treatment. We found a remarkable overexpression of survivin in untreated Ewing sarcoma and a time and dose dependent increase of survivin protein concentration after irradiation with X-ray. The cell-line with the lowest survivin induction showed the highest radiosensitivity. In conclusion, our results show that survivin is an inducible radioresistance factor in Ewing sarcoma. This may open new therapeutic options to treat this aggressive

    Review of current data from the Intergroup Ewing Sarcoma Study (IESS) shows that Ewing sarcoma is rare in bones of the hands and feet. The 12 patients from the IESS protocols with hand or foot Ewing sarcoma are comparable to those already reported in the literature. With the exception of lesions in the calcaneus, the prognosis for disease-free survival is excellent. The radiographic features of hand and foot Ewing sarcoma are generally those of classic Ewing sarcoma: permeation, soft-tissue mass, and often, associated sclerotic reaction. However, with the exception of sclerosis, features suggesting bone reaction and slow tumor growth in these patients were distinctly uncommon compared with Ewing sarcoma in general. Apparently location of the lesion is important, since in the reported cases in the literature and in this series, lesions of the calcaneus fared poorly. The importance of this set of patients therefore relates to awareness and early recognition of an unusual appearance and location of Ewing sarcoma

    About 70% of all Ewing sarcoma (EWS) patients are diagnosed under the age of 20 years. Over the last decades little progress has been made towards finding effective treatment approaches for primarily metastasized or refractory Ewing sarcoma in young patients. Here, in the context of the search for novel therapeutic options, the potential of oncolytic protoparvovirus H-1 (H-1PV) to treat Ewing sarcoma was evaluated, its safety having been proven previously tested in adult cancer patients and its oncolytic efficacy demonstrated on osteosarcoma cell cultures. The effects of viral infection were tested in vitro on four human Ewing sarcoma cell lines. Notably evaluated were effects of the virus on the cell cycle and its replication efficiency. Within 24 h after infection, the synthesis of viral proteins was induced. Efficient H-1PV replication was confirmed in all four Ewing sarcoma cell lines. The cytotoxicity of the virus was determined on the basis of cytopathic effects, cell viability, and cell lysis. These in vitro experiments revealed efficient killing of Ewing sarcoma cells by H-1PV at a multiplicity of infection between 0.1 and 5 plaque forming units (PFU)/cell. In two of the four tested cell lines, significant induction of apoptosis by H-1PV was observed. H-1PV thus meets all the in vitro criteria for a virus to be oncolytic towards Ewing sarcoma. In the first xenograft experiments, however, although an antiproliferative effect of intratumoral H-1PV injection was observed, no significant improvement of animal survival was noted. Future projects aiming to validate parvovirotherapy for the treatment of pediatric Ewing sarcoma should focus on combinatorial treatments and will require the use of patient-derived xenografts and immunocompetent syngeneic animal models.

    Full Text Available Corey F Saba Department of Small Animal Medicine and Surgery, College of Veterinary Medicine, University of Georgia, Athens, GA, USA Abstract: Feline injection site sarcomas (FISS; also known as vaccine-associated sarcomas have been recognized for >20 years. Although uncommon, these tumors are iatrogenic, and vaccination against rabies and feline leukemia virus is perhaps the most common inciting cause. The exact etiopathogenesis is unknown, but it is widely accepted that inflammation induced by vaccines or other injections likely plays a critical role in tumor development. Injection site sarcomas are extremely locally invasive. Multimodal therapy, incorporating combinations of surgery, radiation therapy, and sometimes chemotherapy or immunotherapy, is recommended. However, tumor recurrences are common even with aggressive treatment, and many cats with FISS ultimately succumb to this devastating disease. While vaccination protocols play an important role in the management and control of infectious disease, veterinarians must be diligent in following established vaccination guidelines to minimize individual patient risk of FISS development. Early tumor detection and client education are also vital in the successful treatment of FISS. Keywords: injection site sarcoma, cat, cancer, oncology

    Criteria for the diagnosis of radiation-induced sarcoma have been previously described. All cases must have a history of irradiation and the second neoplasm must have arisen in the area of the radiation field. A latent period of several years must have elapsed after irradiation before clinical evidence of a second malignant neoplasm. Most important thing is that, all suspected cases must have been proved histologically. We have experienced 3 cases of radiation-induced sarcoma, they were 42-years-old man who developed an osteosarcoma of the lumbar spine at the field of postoperative irradiation for seminoma 7 years previously, 69-years-old woman who developed a malignant fibrous histiocytoma of the buttock at the field of radical radiation for uterine carcinoma 7 years previously and 59-years-old woman who developed an extraskeletal osteosarcoma of the abdominal wall at the field of postoperative irradiation for uterine sarcoma 7 years previously. The last case is very rare and only 8 cases of radiation-induced extraskeletal osteosarcoma have been reported. Since there has been a definite trend in the treatment of cancer toward employing radiation for more favorable cases, in addition to technical improvements in the administration of radiotherapy and more modern equipment, survival data may have been altered considerably in many malignant tumors. Accordingly, more radiation-induced tumors may be encountered in the future. The clinical presentation and histopathology of these radiation-induced sarcomas are presented with a review of the literature. (author)

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 (=.006. Complete surgical resection improved overall survival for high-grade tumors (=.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.

    To determine the demographics, imaging findings, clinical symptoms, and prognosis of primary vertebral Ewing's sarcoma (PVES). A retrospective review of medical records and radiological studies of patients diagnosed with PVES from 1936 through 2001 in our institution and Department of Pathology consultation files was undertaken. Metastatic and soft tissue Ewing's sarcoma cases were excluded. From a total of 1,277 cases of Ewing's sarcoma, 125 (9.8%) had a primary vertebral origin. There were 48 females and 76 males. Patient ages ranged from 4 to 54 (mean 19.3, standard deviation 10.7, median 16) years. Vertebral column distribution was four cervical (3.2%), 13 thoracic (10.5%), 31 lumbar (25%), and 67 sacrum (53.2%). More than one vertebral segment was involved in ten cases (8%). Satisfactory imaging studies were available in 51 patients: 49 radiographs, 27 computerized tomography (CT), and 23 magnetic resonance imaging (MRI) studies. The majority of tumors were lytic (93%). Three cases were mixed lytic and sclerotic (6%) and one sclerotic. In the nonsacral spine, the majority of lesions (12/20) involved the posterior elements with extension into the vertebral body. Five cases were centered in the vertebral body with extension into the posterior elements. Two cases were limited to the posterior elements, and one case solely involved the vertebral body. Ala was the most frequently affected site in the sacrum (18/26). Spinal canal invasion was frequent (91%). Detailed clinical information was available in 53 patients. Duration of symptoms ranged from 1 to 30 (mean 7) months. Local pain was the first symptom and seen in all cases. Neurological deficits were present in 21 (40%) cases. All patients received radiation in various dosages; 70% additionally received chemotherapy. Twenty-five patients had surgery, and two patients received bone marrow transplantation. Forty-five patients had follow-up; the five-year disease-free survival probability is 0

    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.

    Full Text Available In carcinomas stromal cells participate in cancer progression by producing proteases such as MMPs. The expression MMP1 is a prognostic factor in human chondrosarcoma, however the role in tumor progression is unknown. Laser capture microdissection and In Situ hybridization were used to determine cellular origin of MMP1 in human sarcomas. A xenogenic model of tumor progression was then used and mice were divided in two groups: each harboring either the control or a stably MMP1 silenced cell line. Animals were sacrificed; the neovascularization, primary tumor volumes, and metastatic burden were assessed. LCM and RNA-ISH analysis revealed MMP1 expression was predominantly localized to the tumor cells in all samples of sarcoma (p = 0.05. The percentage lung metastatic volume at 5 weeks (p = 0.08 and number of spontaneous deaths secondary to systemic tumor burden were lower in MMP1 silenced cell bearing mice. Interestingly, this group also demonstrated a larger primary tumor size (p<0.04 and increased angiogenesis (p<0.01. These findings were found to be consistent when experiment was repeated using a second independent MMP1 silencing sequence. Prior clinical trials employing MMP1 inhibitors failed because of a poor understanding of the role of MMPs in tumor progression. The current findings indicating tumor cell production of MMP1 by sarcoma cells is novel and highlights the fundamental differences in MMP biology between carcinomas and sarcomas. The results also emphasize the complex roles of MMP in tumor progression of sarcomas. Not only does metastasis seem to be affected by MMP1 silencing, but also local tumor growth and angiogenesis are affected inversely.

    The British Childhood Cancer Survivor Study (BCCSS) provides the first detailed investigation of employment and occupation to be undertaken in a large population-based cohort. Previous studies have been limited by design issues such as using small numbers of survivors with specific diagnoses, and involved limited assessment of employment status and occupational level. The BCCSS includes 17,981 5-year survivors of childhood cancer. Employment status and occupational level were ascertained by questionnaire from eligible survivors (n = 14,836). Multivariate logistic regression was used to explore factors associated with employment and occupation, and to compare survivors to their demographic peers in the general population. Employment status was available for 10,257 survivors. Gender, current age, cancer type, radiotherapy, age at diagnosis and epilepsy were consistently associated with being: employed; unable to work; in managerial or non-manual occupations. Overall, survivors were less likely to be working than expected (OR (99% CI): 0.89 (0.81-0.98)), and this deficit was greatest for irradiated CNS neoplasm survivors (0.34 (0.28-0.41)). Compared to the general population, survivors were fivefold more likely to be unable to work due to illness/disability; the excess was 15-fold among CNS neoplasm survivors treated with radiotherapy. Overall survivors were less likely to be in managerial occupations than expected (0.85 (0.77-0.94)). However, bone sarcoma survivors were more likely to be in these occupations than expected (1.37 (1.01-1.85)) and also similarly for non-manual occupations (1.90 (1.37-2.62)). Survivors of retinoblastoma (1.55 (1.20-2.01)) and 'other' neoplasm group (1.62 (1.30-2.03)) were also more likely to be in non-manual occupations than expected. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

  18. FOXM1 is an oncogenic mediator in Ewing Sarcoma.

    Directory of Open Access Journals (Sweden)

    Laura Christensen

    Full Text Available Ewing Family Tumors (Ewing Sarcoma and peripheral Primitive Neuroectodermal Tumor are common bone and soft tissue malignancies of childhood, adolescence and young adulthood. Chromosomal translocation in these tumors produces fusion oncogenes of the EWS/ETS class, with EWS/FLI1 being by far the most common. EWS/ETS chimera are the only well established driver mutations in these tumors and they function as aberrant transcription factors. Understanding the downstream genes whose expression is modified has been a central approach to the study of these tumors. FOXM1 is a proliferation associated transcription factor which has increasingly been found to play a role in the pathogenesis of a wide range of human cancers. Here we demonstrate that FOXM1 is expressed in Ewing primary tumors and cell lines. Reduction in FOXM1 expression in Ewing cell lines results in diminished potential for anchorage independent growth. FOXM1 expression is enhanced by EWS/FLI1, though, unlike other tumor systems, it is not driven by expression of the EWS/FLI1 target GLI1. Thiostrepton is a compound known to inhibit FOXM1 by direct binding. We show that Thiostrepton diminishes FOXM1 expression in Ewing cell lines and this reduction reduces cell viability through an apoptotic mechanism. FOXM1 is involved in Ewing tumor pathogenesis and may prove to be a useful therapeutic target in Ewing tumors.

Additionally, after failure of first-line therapy, there are relatively few treatment options from which to choose. The novel tubulin-binding drug, eribulin, with a unique mechanism of action from taxanes or vinca alkaloids, has shown clinical activity in several different types of cancers. Eribulin has been approved by the US Food and Drug Administration (FDA for patients with metastatic breast cancer previously treated with an anthracycline or a taxane and has recently been FDA approved for patients with unresectable or metastatic liposarcoma who have failed a previous anthracycline regimen. Here, we review current standard treatments of STS, a background of eribulin, the studies that have propelled eribulin to FDA approval for liposarcoma, and future directions of the drug. The benefits of eribulin in STS are discussed in detail, especially with regard to the recent pivotal Phase III study comparing eribulin to dacarbazine for leiomyosarcoma and adipocytic sarcoma.

    Patients diagnosed with retroperitoneal sarcoma at the Hospital San Juan de Dios were characterized during the years 2007 to 2012. The population framework was taken from the hospital's Pathology service database. A total of 15 patients older than 12 years with a diagnosis of sarcoma or malignant fibrous histiocytoma and that the site of origin of the biopsy was the retroperitoneum were selected. The data of the selected patients were collected through a data collection form. The variables included were: age, sex, origin, dates of importance (income, discharge, surgery, complication), presence and type of complications, pathological staging, type of surgery, comorbidities, presence and date of recurrence, treatment with chemotherapy and radiotherapy, death and causes of death. A descriptive analysis with the calculation of frequency measurements (absolute and relative) was carried out to describe the occurrence of the event. The analysis of proportional risks was performed considering the relationship between death and time, the possible relationship with the service of approach, clinical stage and resection status was also assessed.

    Myofibroblastic sarcoma is an extremely rare malignant tumor in the oral and maxillofacial region. We report a case of myofibroblastic sarcoma probably induced by irradiation for maxillary sinus cancer. The patient was a 61-year-old man whose present history was as follows. In October 1989, he presented with pain in the left maxillary molar region. A squamous cell carcinoma of the left maxillary sinus was diagnosed, and he was treated with external irradiation of 50 Gy combined with chemotherapy. Left maxillectomy was done in February 1990. The postoperative course was satisfactory. However, in June 1998, he presented again with a tumor arising in the posterior region of the defect on the left side of the maxilla. Although histopathological examination of a biopsy specimen revealed granulation tissue with inflammatory changes, the tumor grew rapidly. The tumor was therefore suspected to be malignant and was resected under general anesthesia. Histopathological examination revealed atypical and spindle tumor cells with immunohistochemically positive staining for α-smooth muscle actin, desmin, vimentin, and muscle specific actin, but negative staining for h-caldesmon. On the basis of these histopathological and clinical findings, a final diagnosis of a myofibroblastic sarcoma of the maxillary region was made. The lesion was strongly suspected to be a radiation-induced tumor. The patient was followed up for 4 years 5 months after operation. The subsequent course was satisfactory, with no signs of recurrence or distant metastasis. (author)

    Myofibroblastic sarcoma or myofibrosarcoma is a malignant tumor of myofibroblasts and known to develop rarely in the breast, but its underlying lesion and tumor cell origin have never been reported yet. A 61-year-old female presented with a gradually growing breast mass with well-demarcated ovoid nodular shape. The tumor was histologically characterized by fascicular-growing spindle cell proliferation with large areas of hyalinized fibrosis and focally ductal epithelial remnants embedded in myxoid stroma, mimicking a fibroadenomatous lesion. It had frequent mitoses of 5-16/10 high-power fields, hemorrhagic necrosis, and focally pericapsular invasion. The spindle cells were diffusely immunoreactive for fibronectin, smooth muscle actin, and calponin, which suggest a myofibroblastic origin. Multiple irregularly thickened vessels with medial or pericytic cell proliferation were found to be merged with the intrinsic tumor cells. The tumor could be diagnosed low-grade myofibroblastic sarcoma arising in an old fibroadenoma. We report a case of a low-grade mammary myofibrosarcoma that showed a background lesion of fibroadenoma first in the worldwide literature and suggest the pericytes or medial muscle cells of the intratumoral vessels as the cell origin of the myofibroblastic sarcoma.

    Full Text Available Synovial sarcomas (SS are classified as subgroup of soft tissue sarcomas affecting mainly extremities of young adults. Primary SS of kidney are very rare tumours with poor prognosis. Though they have characteristic histology and immunohistochemistry (IHC due to rarity of incidence it is difficult to diagnose them. Sometimes chromosomal rearrangement studies are required to confirm the diagnosis. We are presenting a case of 41-year-old male who was referred to our cancer centre for evaluation of left renal mass. CT scan of abdomen revealed a large left renal mass encasing the aorta. Biopsy of renal mass revealed poorly differentiated sarcoma and IHC was positive for vimentin, CD99, and BCL2 and negative for AE1, epithelial membrane antigen, and leukocyte common antigen. The patient was clinically inoperable as renal mass was encasing the aorta. So he was subsequently offered palliative chemotherapy in form of ifosfamide and adriamycin. CT abdomen shows partial response after 3 cycles of chemotherapy according to RECIST criteria.

Surgical removal is considered the treatment of choice, and patients who have been given conventional radiotherapy have had inferior outcomes. This study is the first describing a case of PLS treated with stereotactic ablative radiotherapy (SABR, which precisely targets a small tumor with a markedly higher biologically effective dose than conventional radiotherapy. The patient was an 82-year-old man who was diagnosed with primary lung leiomyosarcoma based on radiology, pathology, and immunohistochemical examinations. The PLS was located in the right lower lobe and measured 2.5 cm. No regional nodal or distant organ metastasis was observed. He was inoperable medically. The SABR was performed using volumetric modulated arc therapy and a dose of 56 Gy in four fractions. Follow-up computed tomography 2 months after SABR revealed a complete tumor response. The toxicity was limited to mild respiratory symptoms. The patient is alive and has had no evidence of disease for 2 years. This study suggests that SABR can be a safe and effective treatment option for PLS.

    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.

    Sarcoma of prostate origin is rare. Historically, long-term survival rates for adult patients with prostate sarcoma are poor. We analyzed the experience of 1 institution with prostate sarcoma during the last 3 decades. The records of 21 patients with prostate sarcoma were reviewed to identify symptoms at presentation, diagnostic procedures, presence and development of metastases, staging evaluation, histological subtype, grade and size of the primary tumor, and treatment sequence, including surgery, and preoperative and postoperative therapies. Several clinicopathological variables were assessed for prognostic importance. Most patients presented with urinary obstruction. The diagnosis of prostate sarcoma was usually established with ultrasound guided biopsy or transurethral resection. Histological subtypes were leiomyosarcoma in 12, rhabdomyosarcoma in 4, malignant fibrous histiocytoma in 1 and unclassified sarcoma in 4 patients. At last followup, 8 patients had no evidence of disease after a median of 81.5 months (range 10 to 197). The remaining 13 patients died of sarcoma (median survival 18 months, range 3 to 94). The 1, 3 and 5-year actuarial survival rates for all 21 patients were 81%, 43% and 38%, respectively. Factors predictive of long-term survival were negative surgical margins (p = 0.0005) and absence of metastatic disease at presentation (p = 0.0004). Tumor size and grade, and the histological subtype of prostate sarcoma had no significant influence on actuarial survival. The long-term disease specific survival rate for adults with prostate sarcoma is poor. Early diagnosis and complete surgical resection offer patients the best chance for cure.

Classic KS has been seen relatively frequently in Turkey. Our aim was to evaluate the demographic, clinical features of Kaposi sarcoma and etiopathological role of human herpesvirus-8 (HHV-8. Treatment results of 18 classic Kaposi’s sarcoma were also concluded.Material and Method: Eighteen cases of classic Kaposi sarcoma diagnosed as clinically and histopathologically between January 2001 and August 2008 in our dermatology department were taken to this study. Demographic, clinical features and treatment results were reviewed retrospectively in all patients. HHV-8 was investigated in the lesional skin of 7 patients.Results: A male/female ratio of 2/1 was found. Mean age at diagnosis was 67.2 (37-94 years. Bilaterally lower extremities were involved in 15 patients (83.3%, the trunk was involved in 3 patients (16.6%. Plaques and nodules were the common type of lesions (66.6% and 55.5%. Nine patients had no symptoms (50%. Edema was the most common symptom (38.8%. A second primary malignancy was found in 2 patients (11.1%. HHV-8 was detected in 6 of the 7 patients(85.7%. Majority of the patients were treated with interferon alfa (subcutaneously and cryotherapy as a monotherapy or a combination therapy. Imiquimod was the second agent in combined treatment (27.7%. Conclusion: We suggest that interferon alfa and imiquimod can be used as first line therapy agents with their antiviral and immunmodulatuar features in the treatment of KKS.

    Full Text Available The primary and metastatic gastrointestinal synovial sarcoma is rare with a wide differential diagnosis. It usually expresses cytokeratins EMA, BCL2 with an occasional CD99, and S100 positivity but not desmin. We present a case of metastatic synovial sarcoma with unusual immunophenotype causing diagnostic challenges. The tumor cells showed focal cytokeratin, EMA, and, unexpectedly, desmin positivity. Additional intranuclear TLE-1 positivity and negativity for CD34 and DOG-1 were also identified. A diagnosis of monophasic synovial sarcoma was confirmed by using FISH break-apart probe. RT-PCR revealed the SYT-SSX1 fusion gene. Intra-abdominal synovial sarcoma, either primary or metastatic, with unusual desmin positivity raises the diagnostic challenge, since a wide range of differential diagnoses could show a similar immunophenotype (leiomyosarcoma, desmoid tumor, myofibroblastic tumor, and rarely GIST etc.. Typical morphology and focal cytokeratin/EMA positivity should alert to this tumor, and FISH and RT-PCR remain the gold standard for the confirmation.

    A 35-year-old man was diagnosed in 1984 as having a synovial cell sarcoma of his right wrist without evidence of metastatic spread. The patient underwent regional hyperthermic chemoperfusion, wide-field excision, post-operative radiation therapy and systemic adjuvant chemotherapy. In 1986 and in 1987, because of new lesions found on chest radiographs, the patient underwent bilateral staging thoracotomies with resection of pulmonary metastases, followed by chemotherapy and radiotherapy. Later in 1987, a chest radiograph showed a large left hilar mass and multiple bilateral pulmonary nodules. Computerized tomography of the chest demonstrated a left hilar mass and two nodules in the right lower lung, raising the possibility of recurrent pulmonary metastatic cancer. As a diagnostic procedure, In-111 labeled monoclonal antibody (Mab) 19-24, produced against a human malignant fibrous histiocytoma, was infused intravenously, and 48-hour images revealed focal areas of increased uptake corresponding to the lesions seen on CT. At surgery, the lesions were confirmed to be synovial cell sarcoma. Imaging with Mabs specific for sarcoma may be particularly useful in sarcoma patients in whom there is clinical uncertainty regarding the nature of pulmonary lesions. In this case, the Mab was useful in distinguishing tumor deposits from postsurgical scarring and helped to guide subsequent surgery and treatment

    Full Text Available Abstract Background The relationship between radiation exposure for treatment of cancer and occurrence of a second primary cancer at the irradiated site is well known. This phenomenon is however rare in prostate. Case presentation A 75-year-old farmer was treated for rectal cancer with preoperative 45 Gy of radiotherapy and abdominoperineal resection. Four years later he developed symptoms of bladder outlet obstruction and acute urinary retention. He underwent a transurethral resection of the prostate. Histological examination of the removed prostate tissue and immunohistochemistry revealed it to be a poorly differentiated sarcoma. Conclusion We believe this to be the first reported case of radiation-induced sarcoma following radiotherapy treatment for rectal cancer. Since radiotherapy plays a pivotal role in the contemporary treatment of rectal adenocarcinoma, it is relevant to be aware of the potential long-term carcinogenic complications of radiotherapy of the pelvis.

  2. Evaluation of therapeutic results in Ewing's sarcoma

    The philosophy pervading the treatment approach to Ewing's sarcoma was to have therapy encompass all foci of disease, including sites of occult or potential involvement in addition to obvious clinical manifestations. The experience with integrated methods of treatment in 66 consecutive patients at the National Cancer Institute is reviewed. A median survival of 18 months (44 percent 2 year survival rate) for patients with recognizable metastases on admission bears impressive witness to the value of adjuvant therapy in Ewing's sarcoma. Even more encouraging, an uncorrected 5 year survival rate of 53 percent (42 percent continuously free of disease) for patients given ''pyrophylactic'', adjuvant therapy indicates the potential for permanent control of disease in a significant fraction of cases with clinically localized primary tumors.

    A female patient who died of apparent postradiation sarcoma in the inguinal region after irradiating a metastatic squamous cell carcinoma of the same site was reported. For approximately 20 months, the patient had received a total of 6,600 and 9,600 Roentgen to the right para-aortic and inguinal areas, respectively. About 10 years later, she developed a sarcoma, namely a malignant fibrous histiocytoma. Sputum cytology demonstrated numerous giant cells with bizarre nuclei; subsequent chest films also presented apparent metastatic tumor shadows. The cellular characteristics and also rather low incidence of detection of nonepithelial malignant tumor by sputum cytology were briefly discussed, and ways of enhancing cytodiagnostic accuracy were proposed.

    2005-06-01

    Full Text Available Mesenchymal neoplasias represent 5% of tumors affecting the penis. Due to the rarity of such tumors, there is no agreement concerning the best method for staging and managing these patients. Sarcomas of the penis can be classified as deep-seated if they derive from the structures forming the spongy body and the cavernous bodies. Superficial lesions are usually low-grade and show a small tendency towards distant metastasis. In contrast, deep-seated lesions usually show behavior that is more aggressive and have poorer prognosis. The authors report 3 cases of deep-seated primary sarcomas of the penis and review the literature on this rare and aggressive neoplasia.

    Full Text Available Kaposi's sarcoma is a malignant disease that originates in the lymphatic endothelium. It has a broad spectrum of clinical manifestations. Its four distinct clinical forms are: classic, endemic, iatrogenic and epidemic Kaposi's sarcoma. In non-HIV-associated Kaposi's sarcoma, the disease is typically limited to the lower extremities, but in immunodeficient patients, it is a multifocal systemic disease. The clinical course of the disease differs among patients, ranging from a single or a few indolent lesions to an aggressive diffuse disease. Advanced Kaposi's sarcoma lesions, typically those on the lower extremities, are often associated with lymphedema. In this paper, we report a case of a patient with a rare form of AIDS-associated Kaposi sarcoma called lymphangiectatic Kaposis's sarcoma.O sarcoma de Kaposi é uma neoplasia originária do endotélio linfatico, que apresenta um amplo espectro de manifestações, com quatro formas clínicas: sarcoma de Kaposi clássico, endêmico, iatrogêncio e epidêmico ou associado ao HIV. Em pacientes imunocompetentes, a doença é tipicamente limitada às extremidades. Porém em pacientes imunideprimidos, o sarcoma de Kaposi é uma doença sistêmica multifocal. Apresenta cursos clínicos diferentes, desde simples lesões cutâneas isoladas até lesões agressivas e difusas, com ou sem envolvimento sistêmico. Lesões avançadas de sarcoma de Kaposi, principalmente as localizadas nas extremidades, podem apresentar linfedema. Neste trabalho, reportamos caso de paciente com forma rara de Sarcoma de Kaposi associado a Aids, chamada de sarcoma de Kaposi linfangiectásico.

    D'Angelo, S. P.; Tap, W. D.; Schwartz, G. K.; Carvajal, R. D.

    2014-01-01

    Sarcomas are heterogeneous malignant tumors of mesenchymal origin characterized by more than 100 distinct subtypes. Unfortunately, 25–50% of patients treated with initial curative intent will develop metastatic disease. In the metastatic setting, chemotherapy rarely leads to complete and durable responses; therefore, there is a dire need for more effective therapies. Exploring immunotherapeutic strategies may be warranted. In the past, agents that stimulate the immune system such as interferon and interleukin-2 have been explored and there has been evidence of some clinical activity in selected patients. In addition, many cancer vaccines have been explored with suggestion of benefit in some patients. Building on the advancements made in other solid tumors as well as a better understanding of cancer immunology provides hope for the development of new and exciting therapies in the treatment of sarcoma. There remains promise with immunologic checkpoint blockade antibodies. Further, building on the success of autologous cell transfer in hematologic malignancies, designing chimeric antigen receptors that target antigens that are over-expressed in sarcoma provides a great deal of optimism. Exploring these avenues has the potential to make immunotherapy a real therapeutic option in this orphan disease. PMID:24778572

The tarsal bones are involved only 2 percent in the Ewing's sarcoma. Two cases experienced by authors and ten cases published in literatures of Ewing's sarcoma of the tarsal bone were analyzed retrospectively. The result were as follows: 1. Of the tarsal bones, the calcaneus was 7 cases, the talus 4 cases, cuneiform 1 case. 2. Female was affected more commonly than male, the ratio being 4 to 1 in the tarsal bones. 3. About sixty percent of total cases in the tarsal bones had evidence of diffuse sclerotic pattern. All the cases of the talus had evidence of diffuse sclerotic pattern. 4. The diseases to be considered in differential diagnosis are as follows: avascular necrosis, tuberculous osteomyelitis, osteosarcoma, and pyogenic osteomyelitis. 5. The diffuse sclerosis radiographically showed a close relation with dead bone resulting from avascular necrosis due to tumor infiltration histologically. Periosteal reactive new bone and osteoid deposition on the dead bone were also correlated with diffuse sclerosis. 6. Because it is difficult to differentiate sclerotic lesions in the tarsal bones by radiographic methods alone, all such lesions should be subject to biopsy as early as possible

  16. Diagnosis and treatment of Ewing's sarcoma

    Iwamoto, Yukihide

    2007-01-01

    Ewing's sarcoma is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. Ewing's sarcoma has retained the most unfavorable prognosis of all primary musculoskeletal tumors. Prior to the use of multi-drug chemotherapy, long-term survival was less than 10%. The development of multi-disciplinary therapy with chemotherapy, irradiation, and surgery has increased current long-term survival rates in most clinical centers to greater than 50%. In addition, the preferred method of tumor resection has changed; limb salvage has nearly replaced amputation of the affected limb. Limb salvage procedures can be performed in place of amputation without compromising patient survival rates. Recent studies have revealed that the pathognomonic translocations involving the EWS gene on chromosome 22 and an ETS-type gene, which is most commonly the Fli1 gene on chromosome 11, are implicated in more than 95% of Ewing's sarcomas, primitive neuroectodermal tumors and Askin's tumors. Therefore, these lesions have become regarded as a single entity, dubbed the Ewing's family of tumors. Reverse transcription polymerase chain reaction (RT-PCR) to detect EWS-ETS gene arrangements is widely used to confirm the diagnosis of Ewing's family of tumors. Experimental results suggest that inhibition of the signaling pathway downstream of the EWS-ETS gene may lead to the development of molecularly targeted therapy in the future. (author)

    Full Text Available Several maternal and birth characteristics have been reported to be associated with an increased risk of many childhood cancers. Our goal was to evaluate the risk of childhood embryonal solid tumors in relation to pre- and perinatal characteristics.A case-cohort study was performed using two population-based datasets, which were linked through R software. Tumors were classified as central nervous system (CNS or non-CNS-embryonal (retinoblastoma, neuroblastoma, renal tumors, germ cell tumors, hepatoblastoma and soft tissue sarcoma. Children aged <6 years were selected. Adjustments were made for potential confounders. Odds ratios (OR with 95% confidence intervals (CI were computed by unconditional logistic regression analysis using SPSS.Males, high maternal education level, and birth anomalies were independent risk factors. Among children diagnosed older than 24 months of age, cesarean section (CS was a significant risk factor. Five-minute Apgar ≤8 was an independent risk factor for renal tumors. A decreasing risk with increasing birth order was observed for all tumor types except for retinoblastoma. Among children with neuroblastoma, the risk decreased with increasing birth order (OR = 0.82 (95% CI 0.67-1.01. Children delivered by CS had a marginally significantly increased OR for all tumors except retinoblastoma. High maternal education level showed a significant increase in the odds for all tumors together, CNS tumors, and neuroblastoma.This evidence suggests that male gender, high maternal education level, and birth anomalies are risk factors for childhood tumors irrespective of the age at diagnosis. Cesarean section, birth order, and 5-minute Apgar score were risk factors for some tumor subtypes.

    Full Text Available Abstract Introduction Ewing's sarcoma of the calcaneus is rare. About thirty cases with calcaneus involvement have been reported in the literature. Talus skip metastases have rarely been described in the available literature Case presentation We report a case of a 14-year-old Moroccan boy, who presented with Ewing's sarcoma of his right calcaneus, diagnosed by swelling of the calcaneus evolving over a year. Radiography, computed tomography and magnetic resonance imaging showed an important tumoral process of the calcaneus and talus skip metastases. The diagnosis was confirmed with histology after a biopsy. In spite of amputation and postoperative chemotherapy, our patient died six months later due to secondary respiratory distress after lung metastasis. Conclusion Imaging, especially magnetic resonance, is important in the diagnosis of Ewing sarcoma and skeletal skip metastases. Treatment of Ewing's sarcoma consists of chemotherapy, radiation therapy and surgical resection depending on the stage and extent of the disease. With the exception of lesions in the calcaneus, the prognosis for disease-free survival of Ewing's sarcoma of the foot is excellent.

    Postradiation sarcoma of bone is an uncommon but serious sequela of radiation therapy. Seventy-eight Mayo Clinic patients have been treated for sarcomas arising in irradiated bones. They received their initial radiotherapy for a wide variety of nonneoplastic and neoplastic conditions, both benign and malignant. Thirty-five sarcomas arose in bone that was normal at the time of radiotherapy, and 43 arose in irradiated preexisting osseous lesions. The latent period between radiotherapy and diagnosis of sarcoma averaged 14.3 years. Ninety percent of the postradiation sarcomas were either osteosarcomas or fibrosarcomas; chondrosarcoma, malignant (fibrous) histiocytoma, malignant lymphoma, Ewing's tumor, and metastasizing chondroblastoma also occurred. Prompt radical surgery, when feasible, is usually the treatment of choice for the sarcoma. About 30% of patients with sarcomas of the extremities or craniofacial bones survived 5 years without recurrence; there were no disease-free survivors among patients with tumors of the vertebral column, pelvis, or shoulder girdle. The low risk of sarcoma following radiotherapy for the treatment of cancer should not be a contraindication to its use in these patients; however, radiation therapy for benign bone tumors should be reserved for lesions that are not amenable to surgical treatment. An unusual case is also reported herein in which a fibrosarcoma was discovered in the humerus of a patient who had received radiotherapy 55 years previously for a verified osteosarcoma in the same site.

    2017-09-01

    Sarcomas are a rare group of malignant tumors originating from mesenchymal stem cells. Surgery, radiation and chemotherapy are currently the only standard treatments for sarcoma. However, their response rates to chemotherapy are quite low. Toxic side effects and multi-drug chemoresistance make treatment even more challenging. Therefore, better drugs to treat sarcomas are needed. Histone deacetylase inhibitors (HDAC inhibitors, HDACi, HDIs) are epigenetic modifying agents that can inhibit sarcoma growth in vitro and in vivo through a variety of pathways, including inducing tumor cell apoptosis, causing cell cycle arrest, impairing tumor invasion and preventing metastasis. Importantly, preclinical studies have revealed that HDIs can not only sensitize sarcomas to chemotherapy and radiotherapy, but also increase treatment responses when combined with other chemotherapeutic drugs. Several phase I and II clinical trials have been conducted to assess the efficacy of HDIs either as monotherapy or in combination with standard chemotherapeutic agents or targeted therapeutic drugs for sarcomas. Combination regimen for sarcomas appear to be more promising than monotherapy when using HDIs. This review summarizes our current understanding and therapeutic applications of HDIs in sarcomas.

Ninety percent of the postradiation sarcomas were either osteosarcomas or fibrosarcomas; chondrosarcoma, malignant (fibrous) histiocytoma, malignant lymphoma, Ewing's tumor, and metastasizing chondroblastoma also occurred. Prompt radical surgery, when feasible, is usually the treatment of choice for the sarcoma. About 30% of patients with sarcomas of the extremities or craniofacial bones survived 5 years without recurrence; there were no disease-free survivors among patients with tumors of the vertebral column, pelvis, or shoulder girdle. The low risk of sarcoma following radiotherapy for the treatment of cancer should not be a contraindication to its use in these patients; however, radiation therapy for benign bone tumors should be reserved for lesions that are not amenable to surgical treatment. An unusual case is also reported herein in which a fibrosarcoma was discovered in the humerus of a patient who had received radiotherapy 55 years previously for a verified osteosarcoma in the same site

    The poor prognosis of patients with advanced bone and soft-tissue sarcoma has not changed in the past several decades, highlighting the necessity for new therapeutic approaches. Immunotherapies, including oncolytic viral (OV) therapy, have shown great promise in a number of clinical trials for a variety of tumor types. However, the effective application of OV in treating sarcoma still remains to be demonstrated. Although few pre-clinical studies using distinct OVs have been performed and demonstrated therapeutic benefit in sarcoma models, a side-by-side comparison of clinically relevant OV platforms has not been performed. Four clinically relevant OV platforms (Reovirus, Vaccinia virus, Herpes-simplex virus and Rhabdovirus) were screened for their ability to infect and kill human and canine sarcoma cell lines in vitro, and human sarcoma specimens ex vivo. In vivo treatment efficacy was tested in a murine model. The rhabdovirus MG1 demonstrated the highest potency in vitro. Ex vivo, MG1 productively infected more than 80% of human sarcoma tissues tested, and treatment in vivo led to a significant increase in long-lasting cures in sarcoma-bearing mice. Importantly, MG1 treatment induced the generation of memory immune response that provided protection against a subsequent tumor challenge. This study opens the door for the use of MG1-based oncolytic immunotherapy strategies as treatment for sarcoma or as a component of a combined therapy. © 2017 UICC.

    Full Text Available 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.

It may also represent blastic transformation of myelodysplastic syndromes or myeloproliferative neoplasms. Although usually seen in the context of advanced and poorly controlled disease, it may also present as the first manifestation of illness, without concurrent bone marrow or blood involvement. In the medical literature, chloroma and GS are terms that have been used interchangeably with myeloid sarcoma. GS usually manifests as soft tissue or bony masses in several extracranial sites, such as bone, periosteum, and lymph nodes; involvement of the head and neck region is uncommon. We report a case of a woman with insidious onset of progressive nasal congestion and diminished hearing who was diagnosed with an isolated GS of the nasopharynx. With involved field radiotherapy, she achieved a complete remission of 12-months duration before being diagnosed with overt AML. She has remained disease-free for greater than 18 months following induction and consolidation chemotherapy. Through a MEDLINE®/PubMed® search we identified an additional 13 cases of nasopharyngeal GS. The median age was 37 years (range 1 to 81 years. The cases were equally distributed among the sexes. The most common presenting symptoms were conductive hearing loss and sinonasal congestion. Isolated GS was identified in six cases, and the median time from diagnosis of GS to AML was 12 months (range 3 to 48 months. The treatment varied, but responses were seen in all the patients who received

    Abstract Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) are high-grade malignant neoplasms. These malignancies present very rare tumors of thoracopulmonary area and even rarer in the mediastinum. In our knowledge, ES/PNET presented with multiple mediastinal masses has not been reported previously. We experienced a case of a 42-year-old man presented with gradual onset of left-side pleuritic chest pain. A contrast-enhanced chest computed tomography (CT) scan showed separate 2 large heterogeneously enhancing masses in each anterior and middle mediastinum of the left hemithorax. Positron emission tomography-computed tomography (PET-CT) scan revealed high fluorodeoxyglucose (FDG) uptake in the mediastinal masses. After surgical excision for the mediastinal masses, both of the masses were diagnosed as the ES/PNET group of tumors on the histopathologic examination. The patient refused postoperative adjuvant chemotherapy and came back with local tumor recurrence and distant metastasis on 4-month follow-up after surgical resection. We report this uncommon form of ES/PNET. We are to raise awareness that this rare malignancy should be considered as a differential diagnosis of the malignant mediastinal tumors and which can be manifested as multiple masses in a patient. Understanding this rare entity of extra-skeletal ES/PNET and characteristic imaging findings can help radiologists and clinicians to approach proper diagnosis and better management for this highly malignant tumor.

    Objective: to evaluate the therapies utilized in the authors' institution for management of high-grade extremity sarcomas, analyzing the overall survival rates following multidisciplinary treatment. Materials and methods: retrospective study developed in the period from 1993 to 2007 with 36 patients diagnosed with stages IIb/III, submitted to postoperative external beam radiotherapy, with or without boost dose, utilizing high-dose brachytherapy. Results: thirty-six patients underwent surgery followed by adjuvant external beam radiation therapy. Four patients (11%) received boost dose with brachytherapy, and seven (19%) received chemotherapy. The average dose for radiotherapy was 50 Gy (CI 95%: 47-53 Gy), and the four patients with brachytherapy boost received doses ranging from 16.2 to 35 Gy. Chemotherapy was indicated for seven patients (19%) with positive margins. Fifteen patients (42%) presented local or distant recurrence, and all of them progressed to death. Twenty-one patients (58%) remain with no clinical/radiological evidence of local/distant recurrence. The mean follow-up time was 88 months (IC 95%: 74-102). The overall seven years survival rate was 80%. Conclusion: combined surgery and radiotherapy is an effective treatment with excellent outcomes in cases where brachytherapy is associated, with improved overall survival rates. (author)

    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.

    Full Text Available Ewing sarcoma and osteosarcoma represent the two most common primary bone tumours in childhood and adolescence, with bone metastases being the most adverse prognostic factor. In prostate cancer, osseous metastasis poses a major clinical challenge. We developed a preclinical orthotopic model of Ewing sarcoma, reflecting the biology of the tumour-bone interactions in human disease and allowing in vivo monitoring of disease progression, and compared this with models of osteosarcoma and prostate carcinoma. Human tumour cell lines were transplanted into non-obese diabetic/severe combined immunodeficient (NSG and Rag2(-/-/γc(-/- mice by intrafemoral injection. For Ewing sarcoma, minimal cell numbers (1000-5000 injected in small volumes were able to induce orthotopic tumour growth. Tumour progression was studied using positron emission tomography, computed tomography, magnetic resonance imaging and bioluminescent imaging. Tumours and their interactions with bones were examined by histology. Each tumour induced bone destruction and outgrowth of extramedullary tumour masses, together with characteristic changes in bone that were well visualised by computed tomography, which correlated with post-mortem histology. Ewing sarcoma and, to a lesser extent, osteosarcoma cells induced prominent reactive new bone formation. Osteosarcoma cells produced osteoid and mineralised "malignant" bone within the tumour mass itself. Injection of prostate carcinoma cells led to osteoclast-driven osteolytic lesions. Bioluminescent imaging of Ewing sarcoma xenografts allowed easy and rapid monitoring of tumour growth and detection of tumour dissemination to lungs, liver and bone. Magnetic resonance imaging proved useful for monitoring soft tissue tumour growth and volume. Positron emission tomography proved to be of limited use in this model. Overall, we have developed an orthotopic in vivo model for Ewing sarcoma and other primary and secondary human bone malignancies, which

    Full Text Available Granulocytic sarcoma also known as extramedullary myeloid sarcoma or chloroma is an uncommon manifestation of leukemia and presents as a deposit of leukemic cells outside the bone marrow. We report a case of a twenty-five-year-old pregnant woman who presented with progressive dysphagia and recurrent postprandial vomiting. Upper GI endoscopy had shown large flat laterally spread nodular lesions in the cardia and proximal body of stomach. Biopsies from the gastric lesion showed granulocytic sarcoma of the stomach. Concurrent peripheral and bone marrow picture was suggestive of acute myeloid leukemia (AML–M4. There is limited reported literature on granulocytic sarcoma of the stomach. Concurrent gastric granulocytic sarcoma involving cardia and AML in pregnancy has not been reported till date.

    Sarcoma is a rare tumor type that occurs most frequently in connective tissue. Despite its uncommon occurrence, sarcoma research has provided the means for groundbreaking research that has advanced our understanding of general cancer mechanisms. It is through sarcoma research that the pioneering efforts of cancer immunotherapy were explored, that we understand the inherent genetic nature of cancer mutations, and that we appreciate the subclassification of general cancer types to make more accurate prognoses. This review explores the brief history of sarcoma research and what sarcomas can still teach us about the future of cancer research, especially in regard to novel immunotherapy targets, the role of epigenetics in disease progression and chemoresistance, and the benefits of more focused clinical trials.

    Soft tissue sarcomas are a group of heterogeneous neoplasms with more than 50 histological subtypes exhibiting major differences in terms of pathogenesis, genetic alterations and clinical behavior. Sarcomas represent approximately 1% of malignancies with retroperitoneal sarcomas representing 10-15% of all soft tissue sarcomas. Surgery is currently the only modality which offers the chance of cure. Surgery for retroperitoneal sarcomas presents specific challenges due their location in a complex space surrounded by vital structures and visceral organs often prohibiting resection with wide margins. Furthermore, even after complete resection local recurrence is common and the leading cause of death. In this article the authors describe the initial investigations, prognostic factors and optimal surgical management. The evidence and current research as regards the role of multimodality treatment is reviewed and discussed.

    Full Text Available Synovial sarcoma (SS is a rare malignant neoplasm that arises most commonly in joint capsules and articular tendons, but its relationship to the synovium is not always obvious. Synovial sarcoma is a malignant soft tissue tumor representing 5.6% to 10% of all soft tissue sarcomas. They are termed SS because of their histologic resemblance to the synovium, but they rarely involve a synovial structure and are thought to arise from pluripotential mesenchymal cells. The tumor usually occurs in close association with tendon sheaths, bursae, and joint capsules, primarily in the para-articular regions of the extremities, with approximately 9% occurring in the head and neck region. Synovial sarcoma has been reported rarely in the oral cavity. We report a very rare case of Synovial sarcoma of the buccal mucosa in a 24-year-old male patient.

    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.

    2011-01-01

    Full Text Available The origin of Ewing's sarcoma is a subject of much debate. Once thought to be derived from primitive neuroectodermal cells, many now believe it to arise from a mesenchymal stem cell (MSC. Expression of the EWS-FLI1 fusion gene in MSCs changes cell morphology to resemble Ewing's sarcoma and induces expression of neuroectodermal markers. In murine cells, transformation to sarcomas can occur. In knockdown experiments, Ewing's sarcoma cells develop characteristics of MSCs and the ability to differentiate into mesodermal lineages. However, it cannot be concluded that MSCs are the cell of origin. The concept of an MSC still needs to be rigorously defined, and there may be different subpopulations of mesenchymal pluripotential cells. Furthermore, EWS-FLI1 by itself does not transform human cells, and cooperating mutations appear to be necessary. Therefore, while it is possible that Ewing's sarcoma may originate from a primitive mesenchymal cell, the idea needs to be refined further.

    Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses

    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 the current time. 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. PMID:27132463

    Full Text Available A 10-year-old castrated male Golden retriever, weighing 36.3 kg was referred for evaluation owing to a decline in general condition. Findings from the complete blood count revealed a marked lymphocytosis (113 000/µℓ. Examination of Wright-Giemsa-stained films of peripheral blood revealed the presence of large granular lymphocytes (LGL. Seventy-two per cent (81 360/µℓ of the lymphocytes were found to be 12-17 µm in diameter, containing nuclei with mature clumped chromatin and abundant lightly basophilic cytoplasm with a variable number of fine azurophilic granules. Based on these findings this case was diagnosed as LGL leukaemia. As a result of multiple-agent chemotherapy, the markedly elevated levels of lymphocytes gradually decreased to 7500/µℓ on day 122 and the patient maintained a good quality of life for the following 3 months. However, on around day 237, a soft, raised, bosselated mass on the labial region was noted. The dog was diagnosed as having histiocytic sarcoma based on cytological and histological examination of the mass. Shortly after diagnosis, the dog developed sudden onset of central nervous system signs and died on day 270. A common outcome of canine LGL is the development of acute blast crisis or lymphoma. However, this case was notable for complication with histiocytic sarcoma from another origin.

    Full Text Available BACKGROUND Ewing’s Sarcoma is an aggressive malignant neoplasm most frequently manifesting in the second decade of life and accounting for 4% of childhood and adolescent malignancies. These tumours were first described by James Ewing in 1921 as tumours that arise from bone. These osseous lesions have since become infamous for their highly aggressive course with 20% to 30% of patients having evidence of metastasis at the time of diagnosis and an estimated 10-year survival rate of 50%. Metastases to the CNS have most recently been estimated to occur in less than 5% of cases and are usually due to direct extension of an osseous lesion into the extradural space or more rarely through haematogenous spread. CASE REPORT In this article, we report a case of 17-year-old boy who presented to the radiology department with complaints of recurrent episodes of headache and vomiting for the past 3 days. On radiological investigation, there was a large well-defined, lobulated, extra-axial mass lesion measuring 3.6 X 5.7 X 5.9 cm noted in the supratentorial left occipital region which was fairly enhancing after contrast administration. The mass was causing permeative type of destruction of the left occipital bone and extending into extracranial soft tissue. Final diagnosis was done by biopsy and histopathology which showed “Atypical Ewing’s Sarcoma” of the left occipital bone. Considering its unusual site and soft tissue extension, we report this case of Primary Atypical Ewing’s sarcoma of occipital bone. CONCLUSION Primary cranial Ewing's sarcoma is to be considered in the differential diagnosis in children with a tumour involving the skull with destruction of the bone and presence of extra-axial soft tissue swelling. CT is the excellent modality for demonstration of bone destruction while MRI depicts soft tissue extension and metastasis if any.

    Purpose: The purpose of this study was to evaluate the variability in target volume and organ at risk (OAR) contour delineation for retroperitoneal sarcoma (RPS) among 12 sarcoma radiation oncologists. Methods and Materials: Radiation planning computed tomography (CT) scans for 2 cases of RPS were distributed among 12 sarcoma radiation oncologists with instructions for contouring gross tumor volume (GTV), clinical target volume (CTV), high-risk CTV (HR CTV: area judged to be at high risk of resulting in positive margins after resection), and OARs: bowel bag, small bowel, colon, stomach, and duodenum. Analysis of contour agreement was performed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: Ten radiation oncologists contoured both RPS cases, 1 contoured only RPS1, and 1 contoured only RPS2 such that each case was contoured by 11 radiation oncologists. The first case (RPS 1) was a patient with a de-differentiated (DD) liposarcoma (LPS) with a predominant well-differentiated (WD) component, and the second case (RPS 2) was a patient with DD LPS made up almost entirely of a DD component. Contouring agreement for GTV and CTV contours was high. However, the agreement for HR CTVs was only moderate. For OARs, agreement for stomach, bowel bag, small bowel, and colon was high, but agreement for duodenum (distorted by tumor in one of these cases) was fair to moderate. Conclusions: For preoperative treatment of RPS, sarcoma radiation oncologists contoured GTV, CTV, and most OARs with a high level of agreement. HR CTV contours were more variable. Further clarification of this volume with the help of sarcoma surgical oncologists is necessary to reach consensus. More attention to delineation of the duodenum is also needed.

    Soft tissue sarcomas (STS) are relatively rare malignant neoplasms arising from the mesenchymal connective tissues. There are some 5600 newly diagnosed patients with STS per year. These tumors occur at all anatomic sites within the body and are of many histologic subtypes. Etiologic factors, including occupational risks, the role of environmental carcinogens, radiation and genetic diseases in the development of these tumors will be mode. The molecular biology of soft tissue sarcomas including the role of several oncogenes and suppressor genes (e.g. Rb, p53, MDM2) will be reviewed. Cytogenetic alternations with an emphasis on molecular diagnostic techniques will be reviewed. The natural history of these tumors will be described with reference to local invasion and spread to regional and distal sites. The evaluation of the patients suspected of having a sarcoma of soft tissue will then be considered including the relative roles of various imaging modalities. The timing and type of biopsy (including FNA, core needle biopsy, incisional biopsy or excisional biopsy) for tumors at various sites and sizes will be addressed. Assessment of histopathologic subtype of the tumor by standard H and E stains, immunohistochemistry, electron microscopy and cytogenetic studies will then be discussed. The principal role for radiation in the management of patients with sarcoma of soft tissue is in combination with surgery. This may be: 1) pre-operative and or post-operative use of external beam photons, electrons, and protons, and 2) intra-operative use of electron beam techniques, or 3) post-operative brachytherapy. Results of these various treatment options with respect to local control, disease-free survival and overall survival will be considered for each of the various techniques with respect to size, grade, histologic type, surgical margin status, anatomic site, primary vs. recurrent disease. Similarly, the factors associated with delay in wound healing are to be considered and

    To explore the effect of neo-adjuvant chemotherapy and computer-assisted surgery on children and adolescents with primary pelvic Ewing's sarcoma, and assess the therapeutic effect on the pelvic skeletal growth and development. This is a retrospective analysis of 10 children with primary pelvic Ewing's sarcoma treated between Jan 2001 and Oct 2010 at the Department of Oncologic Orthopaedics at Xijing Hospital. There were 3 girls and 7 boys in the age of 7 to 16 years (average 12.7 years). All patients were pathologically diagnosed as Ewing's sarcoma. There were two cases in the sacroiliac joint, one in the ilium, one in the pubic bone, and 6 cases in peri-acetabular area including 5 below the triradiate cartilage and one above the triradiate cartilage, without cartilage invasion. All patients underwent neo-adjuvant chemotherapy, resection and reconstruction surgery and postoperative chemotherapy. CDP, ADM and IFO regimen chemotherapy were given as the main treatment. Five cases were treated by traditional resection and reconstruction, and after 2008, five cases were treated by computer-assisted surgery. During the reconstruction, the hip rotation center was put at a depressed location. All of the 10 cases underwent postoperative radiotherapy in a dose of 45-55 Gy. All patients were followed-up for 12-72 months (mean: 37.8 months). One child had tumor recurrence and lung metastasis and 9 patients had no evidence of disease (NED). After neo-adjuvant chemotherapy, the oncologic statuses (RECIST) were: 1 CR, 8 PR and 1 SD. The functional recoveries after surgery (Enneking's) were: 4 cases excellent, 4 good, 1 fair and 1 poor. Five cases who underwent computer-assisted surgery achieved a good reconstruction without local recurrence. There were no effects on skeletal growth in 8 cases. An unbalanced hip rotational center occurred in one case, and a compemsatory scoliosis was found in another case. There were no serious complications in all patients. The comprehensive

    In a register study all women in the West of Sweden Health Care Region with a breast cancer diagnosed between 1960 and 1980 (n = 13 490) were followed up in the Swedish Cancer Register to the end of 1988 for later occurrence of a soft tissue sarcoma (STS). Nineteen sarcomas were reported, whereas 8.7 were expected and the relative risk (RR) was 2.2 (CI 95% 1.3-3.4). The absolute risk was (1.7(10 4 )) person years (PY) in comparison with 0.8 expected. To obtain a more detailed analysis of the associations between arm lymphoedema, radiotherapy and STS development, and to control the quality of the register data, a case control study was also performed. Clinical records from the different hospitals in the region were collected for all the 19 cases as well as for three selected controls per case. The histopathology of the cases were reviewed, and one of the cases was reclassified as a malignant melanoma and excluded from further analysis. Thirteen of the cases were clustered around the treated breast area. To quantify the exposure to radiotherapy, the integral dose was estimated. The presence of lymphedema was included as a binary variable in the analysis. The exact conditional randomisation test indicated a significant correlation between the integral dose and the development of an STS (p = 0.008) and this association was still significant after stratification for arm oedema. A conditional logistic regression analysis with STS as the dependent variable and the integral dose as the explanatory variable gave an odds ratio (OR) of(5.2(100)) J (CI 95% 1.3-21.2), and if this regression was restricted only to the STS developing in the radiation fields the OR was(3.2(100)) J (CI 95% 0.8-12.9). Thus, the excess of STS in this breast cancer cohort was very low ((0.9(10 4 )) PY). However the integral dose correlates well to the development of STS and can be useful in quantifying even small risks of secondary malignancies in the breast cancer population

    Full Text Available This article describes the medical, psychological, and social challenges encountered during home-based, family-centred palliative care of a 3-year-old female with secondary histiocytic sarcoma diagnosed during treatment for T-cell acute lymphoblastic leukaemia. Histiocytic sarcoma is an exceedingly rare cancer in adults, but even less frequent and highly aggressive when presenting as a secondary cancer in children. Comprehensive, multidisciplinary paediatric hospice care services are not widely available across Slovakia,thus limiting the number of patients and families offered such highly specialized end-of-life care. This case study illustrates the primary benefits for the child and family of such a program as well as the impact on the medical and nursing professionals working in the fi eld of paediatric haematology-oncology.

    Peripheral primitive neuroectodermic tumor (PNET) or peripheral neuro epithelioma is a malignant neoplasia consisting of round small blue cells, which derive from the neural crest. Amongst malignant tumors it is one the least differentiated histological types. Ewings sarcoma and PNET are morphologically impossible to differentiate; they are also very similar pathologically in terms of their imagining appearance. Due to these similarities we will consider them as a single entity. These can appear in infants, but are more common in adolescents. Treatment includes hemo therapy,surgery and radiotherapy. We present a case of an 8 year old female patient, diagnosed with Ewing Sarcoma, confirmed by histopathology and immunohistochemistry, we will also present a brief review of the literature.

    A 10-year-old, neutered male, Maltese dog presented with a three week history of intention tremor, right hind limb rigidity, poor coordination, and occasional circling to the left. On magnetic resonance imaging (MRI) of the brain, a mass was identified in the right occipital lobe and cerebellum. Three weeks after the initial MRI scan, we performed an sup(18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) of the brain. The FDG-PET demonstrated areas of hypermetabolism in the right occipital lobe, cerebellum, pons, and medulla oblongata. When the standardized uptake value was calculated, the hypermetabolic lesion was higher than the gray matter values. The anatomical location of the hypermetabolic lesion was more precisely identified by the PET-MRI fusion images. The dog was definitively diagnosed as a primary histiocytic sarcoma of the brain. This is the first report of PET findings of an intracranial histiocytic sarcoma in a dog

    We describe a case report of a man aged 56 years with a 4-month history of right-sided sciatica-type pain with subclinical disc prolapse evident on MRI. Worsening pain together with the appearance of a tender mass in his right buttock prompted further imaging, which demonstrated an infiltrative mass engulfing the lumbosacral plexus. This was later shown to be a granulocytic sarcoma on biopsy. Intervertebral disc herniation can be an incidental finding and is not always the cause of sciatica. 2017 BMJ Publishing Group Ltd.

    The most serious complication of Paget's disease is sarcomatous degeneration of pagetic bone. Multifocal sarcomatous degeneration occurs mainly in polyostotic Paget's disease. Multifocal Paget's sarcoma is uncommon and can arise in any site. We report two cases of synchronous multifocal sarcomatous degeneration. The two patients were elderly women (aged 77 and 86 years, respectively) who developed sarcomatous lesions concomitantly, in the first case report in left ilium, left tibia, and first lumbar vertebra and in the second case report in the skull, right ilium, and sacrum. Whether these cases are due to the simultaneous development of several primaries or to metastases from a single primary remains unclear. (orig.)

    Surgery is potentially curative for primary non-metastatic retroperitoneal soft tissue sarcomas (RPS), although patients remain at risk for local recurrence. To reduce this risk, the addition of radiotherapy to radical surgery may be considered. Nevertheless, level I evidence to support radiotherapy is currently lacking. The results from the EORTC-STBSG 62092-22092 studying this question are awaited.

    Ewing's Sarcoma (ES) is the most frequent malignant bone tumor of the foot. The radiological picture is characterized, in 14 patients, by a pure osteolytic lesion (9 cases) or by a mixed one (5 cases); the interruption of the cortical bone and swelling of the soft tissues were always present; the periostal reaction was occasional. The radiological aspects cannot be considered typical of the ES and it is suggested that biopsies should always be performed in the presence of structural alteration of the bone

    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.

  19. Considerations for the long term treatment of pediatric sarcoma survivors

    2018-01-01

    Full Text Available Sarcomas are primary malignancies of the connective tissues. They are exceedingly rare in adults, but much more common in children. The historically recent advent of cytotoxic chemotherapy for pediatric sarcomas has revolutionized the treatment of these diseases and dramatically improved their prognoses. There is thus a population of pediatric sarcoma survivors that are “coming of age” as adults. However, this progress is not without consequences. Due to aggressive treatment protocols that include various combinations of surgery, chemotherapy, and radiation therapy, pediatric sarcoma survivors are at risk of myriad physical, medical, and psychological difficulties as they enter adulthood. These include but are not limited to physical disabilities, chemotherapy-induced cardiac issues, second malignancies, and anxiety. These patients pose unique challenges to their adult primary care physicians. One possible solution to these challenges is multidisciplinary sarcoma survivorship clinics. By paying greater attention to the unique issues of pediatric sarcoma survivors, involved physicians can maximize the physical and emotional health of pediatric sarcoma survivors.

    Sarcomas are rare and complex malignancies that have been associated with a poor prognostic outcome. Over the last few decades, traditional treatment with surgery and/or chemotherapy has not significantly improved outcomes for most types of sarcomas. In recent years, there have been significant advances in the understanding of specific gene mutations that are important in driving the pathogenesis and progression of sarcomas. Identification of these new gene mutations, using next-generation sequencing and advanced molecular techniques, has revealed a range of potential therapeutic targets. This, in turn, may lead to the development of novel agents targeted to different sarcoma subtypes. In this review, we highlight the advances made in identifying sarcoma gene mutations, including those of p53, RB, PI3K and IDH genes, as well as novel therapeutic strategies aimed at utilizing these mutant genes. In addition, we discuss a number of preclinical studies and ongoing early clinical trials in sarcoma targeting therapies, as well as gene editing technology, which may provide a better choice for sarcoma patient management.

    Ewing's sarcoma is a highly malignant bone tumor found in children and adolescents, and the origin of this malignancy is not well understood. Here, we introduced a Ewing's sarcoma-associated genetic fusion of the genes encoding the RNA-binding protein EWS and the transcription factor ETS (EWS-ETS) into a fraction of cells enriched for osteochondrogenic progenitors derived from the embryonic superficial zone (eSZ) of long bones collected from late gestational murine embryos. EWS-ETS fusions efficiently induced Ewing's sarcoma-like small round cell sarcoma formation by these cells. Analysis of the eSZ revealed a fraction of a precursor cells that express growth/differentiation factor 5 (Gdf5), the transcription factor Erg, and parathyroid hormone-like hormone (Pthlh), and selection of the Pthlh-positive fraction alone further enhanced EWS-ETS-dependent tumor induction. Genes downstream of the EWS-ETS fusion protein were quite transcriptionally active in eSZ cells, especially in regions in which the chromatin structure of the ETS-responsive locus was open. Inhibition of β-catenin, poly (ADP-ribose) polymerase 1 (PARP1), or enhancer of zeste homolog 2 (EZH2) suppressed cell growth in a murine model of Ewing's sarcoma, suggesting the utility of the current system as a preclinical model. These results indicate that eSZ cells are highly enriched in precursors to Ewing's sarcoma and provide clues to the histogenesis of Ewing's sarcoma in bone.

    Full Text Available Many years ago the treatment of sarcoma was radiotherapy up to 2000-4000 rad. This treatment was very complicated, due to producing neoplasm after radiotherapy. By this method of treatment of osteosarcoma, the rate of survival became about 20% (two years. The second method of treatment was chemotherapy for a period of 2-5 weeks that amputation was performed afterwards. By chemotherapy, the rate of being alive reached up to 25-27% (five years. Right now, the best treatment for sarcoma is limb salvage. In our report, the chance of being alive in chondrosarcoma was about four years. This was nearly the same as that of the other institutes in the world especially in America, Europe, and Japan. The rate of recurrence was also more than that from different parts of the world. The survival rate in osteosarcomatic patients was about two years less for males the females, and it was more in tall people than short ones. The survival rate of the patients with giant cell tumor was more than osteosarcoma up to five years, and it has no recurrence or metastasis

    1996-01-01

    Over the period 1981-1995, 32 patients with non-metastatic Ewing sarcoma, aged 2 to 22 years, underwent treatment and follow-up study. A locally advanced tumor is found in 85% of patients. Complex radio- and chemotherapy is carried out in all patients, and additional radical surgery - in eight. 60 Co-radiotherapy with gradual radiation field reduction is applied, applying a local dose of 60 - 64 Gy in the tumor area. Chemotherapy is performed according to the VACA protocol. Local tumor control is achieved in all patients with primary tumor located in long bones, and only in 1 of 5 patients with pelvic localization. The overall survival established is as follows: 1 year survival - 100 %, 2 years - 50 %, 3 years - 40 % and 5 years - 34 %. Local recurrence is recorded in 2 cases (6.2%). The distant metastases observed involve the lungs (13), bones (4), lung and bones (2) and soft tissues (3). The Ewing sarcoma is sensible to chemo- and radiotherapy, but the conventional methods do not improve survival. Based on the analysis of the clinical results, emphasis is laid on the necessity of complex treatment with a special reference to alternative therapeutic approaches. 13 refs., 4 figs., 2 tabs

    To find and evaluate characteristic magnetic resonance imaging (MRI) patterns for the differentiation between Ewing sarcoma and osteomyelitis. We identified 28 consecutive patients referred to our department for MRI (1.5 T) of an unclear bone lesion with clinical symptoms suggestive of Ewing sarcoma or osteomyelitis. MRI scans were re-evaluated by two experienced radiologists, typical MR imaging features were documented and a diagnostic decision between Ewing sarcoma and osteomyelitis was made. Statistical significance of the association between MRI features and the biopsy-based diagnosis was assessed using Fisher's exact test. The most clear-cut pattern for determining the correct diagnosis was the presence of a sharp and defined margin of the bone lesion, which was found in all patients with Ewing sarcoma, but in none of the patients with osteomyelitis (P < 0.0001). Contrast enhancing soft tissue was present in all cases with Ewing sarcoma and absent in 4 patients with osteomyelitis (P = 0.0103). Cortical destruction was found in all patients with Ewing sarcoma, 4 patients with osteomyelitis did not present any cortical reaction (P = 0.0103). Cystic or necrotic areas were identified in 13 patients with Ewing sarcoma and in 1 patient with osteomyelitis (P = 0.004). Interobserver reliability was very good (kappa = 1) in Ewing sarcoma and moderate (kappa = 0.6) in patients with osteomyelitis. A sharp and defined margin, optimally visualized on T1-weighted images in comparison to short tau inversion recovery (STIR) images, is the most significant feature of Ewing sarcoma in differentiating from osteomyelitis.

    1983-01-01

    Among 910 survivors of childhood cancer, four developed infiltrating carcinoma of the breast and another had noninfiltrating breast tumor. Expected frequency was 0.3 cases of breast cancer in the series. The affected women developed breast carcinoma at ages 20, 25 and 38 years, and the men at ages 38 and 39 years, respectively. Each patient had received orthovoltage chest irradiation for treatment of Wilms' tumor or bone sarcoma between seven and 34 years previously, and estimated radiation dose to the breast exceeded 300 rad in each instance. Four patients also received diverse forms of chemotherapy. Survivors of childhood cancer have increased risk of developing breast cancer and should undergo periodic screening, particularly after breast tissue had been irradiated. Individualized radiotherapy planning can help exclude the breasts from treatment fields for some thoracic neoplasms

    Epidemiologic evidence supports a relationship between vaccination of cats for rabies and feline leukemia virus with the development of soft tissue sarcomas at the site of administration. These tumors are locally invasive and histologically aggressive. As with high-grade soft tissue sarcoma in humans, combination treatment with radiation therapy and surgery provides for optimum tumor control. Feline vaccine-associated sarcoma has become a difficult issue for the veterinary profession for legal, ethical, and clinical reasons. Although most research efforts have focused on therapeutic intervention, this tumor has great potential to provide an informative model for carcinogenesis and genetic susceptibility applicable to cancer in all species, including humans.

    Synovial sarcomas are a less common cervical tumor in young patients. We report a 23-year-old man with synovial sarcoma in the submandibular region. T2-weighted MR images demonstrated a mixed-intensity tumor attached to the submandibular gland. T1-weighted MR images revealed a focal area with mildly increased signal intensity, indicating intratumoral hemorrhage. MR images were also useful for visualization of tumor extension. Synovial sarcoma should be considered in the differential diagnosis of well-defined in homogeneous tumors adjacent to the submandibular gland in young adults. (author)

    The purpose of this study was to investigate the childhood antecedents of personality disorders that are diagnosed in adolescence. A randomly selected community sample of 641 youths was assessed initially in childhood and followed longitudinally over 10 years. Childhood behavior ratings were based on maternal report; diagnoses of adolescent personality disorders were based on data obtained from both maternal and youth informants. Four composite measures of childhood behavior problems were used: conduct problems, depressive symptoms, anxiety/fear, and immaturity. Adolescent personality disorders were considered present only if the disorders persisted over a 2-year period. For all analyses, personality disorders were grouped into the three clusters (A, B, and C) of DSM-III-R. Logistic regression analyses indicated that all four of the putative childhood antecedents were associated with greater odds of an adolescent personality disorder 10 years later. Childhood conduct problems remained an independent predictor of personality disorders in all three clusters, even when other childhood problems were included in the same regression model. Additionally, depressive symptoms emerged as an independent predictor of cluster A personality disorders in boys, while immaturity was an independent predictor of cluster B personality disorders in girls. No moderating effects of age at time of childhood assessment were found. These results support the view that personality disorders can be traced to childhood emotional and behavioral disturbances and suggest that these problems have both general and specific relationships to adolescent personality functioning.

    Full Text Available An eleven-year-old boy presented with a swelling in his left elbow. Radiologically the features were that of an Ewing′s sarcoma involving the ulna. Histopathology showed small round cell tumor strongly positive for Monoclonal Imperial Cancer research fund 2 (MIC2 antigen. Similar cells in the bone marrow were involved with MIC2 positivity. The patient developed skin lesions, which on biopsy were found to be chloromas. The initial biopsies were reevaluated with special stains revealing granulocytic sarcomas in acute myeloid leukemia masquerading as Ewing′s due to its MIC2 positivity. The possibility of myeloid neoplasms should be considered routinely with known MIC2 positive round cell tumors.

    The authors have developed several monoclonal antibodies against human osteogenic sarcoma, one of which; OST7 (IgGl) selectively localized in osteogenic sarcoma xenografts in nude mice. In the present study, F(ab')/sub 2/ fragment was compared with whole IgG and those labeled with In-111 as well as I-131 were used as a radiotracer for the scintigraphic imaging of tumors. IgC and F(ab')/sub 2/ were labeled with I-131 using chloramine-T method and injected into nude mice bearing human osteogenic sarcoma. Scintigrams at day 2 clearly delineated the site of tumors with almost no radioactivity in other organs with F(ab')/sub 2/, which yielded much better images than whole IgG. Tumor-to-blood ratio of 6.09-27.87 was obtained at day 2 using F(ab')/sub 2/, whereas it was 0.76-1.12 at day 2 and 2.05-3.27 at day 7 with IgG. I-131 labeled nonspecific F(ab')/sub 2/ or IgG resulted in no or very low tumor uptake with tumor-to-blood ratio of 0.94-1.18 at day 2 for F(ab')/sub 2/ and 0.67-0.76 at day 7 for IgG, respectively. In-111 labeled F(ab')/sub 2/ fragment of OST7, which was prepared using DTPA as a bifunctional chelate, also showed a high tumor accumulation with tumor-to-blood ratio of 11.67-17.54 at day 2, but higher background activity in the liver and kidney was observed than I-131 labeled one. These results indicate that F(ab')/sub 2/ fragment of OST7 labeled with either I-131 or In-111, has a great potential for the radioimmunoimaging of osteogenic sarcoma

    Synovial sarcoma (SS) arises in soft tissues but may invade adjacent bone. We describe a case of SS presenting as aggressive lysis of the proximal ulna, the imaging of which suggested a primary bone lesion. Needle biopsy showed a 'small round blue cell tumour', and a primitive neuroectodermal tumour (PNET)/Ewing sarcoma was suggested on the basis of the imaging appearances. The definitive diagnosis of synovial sarcoma was made following molecular genetic studies, which demonstrated a fusion product incorporating the genes SYT and SSX1. The importance of correct diagnosis to guide appropriate management, and, therefore, the necessity for molecular genetic studies, is discussed. (orig.)

    Full Text Available Adenocarcinoma and squamous cell carcinoma account for the vast majority of oesophageal malignancies. Other malignancies known to occur in the oesophagus include melanoma, sarcoma, and lymphoma. Among the sarcomas, carcinosarcoma is the commonest with both carcinomatous and sarcomatous elements followed by leiomyosarcoma of mesenchymal origin. Other sarcomas reported in the literature are liposarcoma, synovial sarcoma, myxofibrosarcoma, Ewing's sarcoma, granulocytic sarcoma, histiocytic sarcoma, schwannoma rhabdomyosarcoma, and epithelioid sarcoma. We report a case of malignant spindle cell tumour of oesophagus. Sarcomas of esophagus present as a polypoid exophytic soft tissue mass. Our patient presented with a stricture which is a rare presentation. Locally aggressive treatment with surgery is beneficial, and local palliative treatment including radiotherapy is worthwhile.

    Background: The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined. Aim: To report a Chilean experience with NSNE tumors evaluated using PET with FDG. Material and Methods: 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. Results: 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. Conclusions: 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.

    Sarcoma is a large and heterogeneous group of malignant mesenchymal neoplasms with significant histological overlap. Accurate diagnosis can be challenging yet important for selecting the appropriate treatment approach and prognosis. The currently torrid pace of new genomic discoveries aids our classification and diagnosis of sarcomas, understanding of pathogenesis, development of new medications, and identification of alterations that predict prognosis and response to therapy. Unfortunately, demonstrating effective targets for precision oncology has been elusive in most sarcoma types. The list of potential targets greatly outnumbers the list of available inhibitors at the present time. This review will discuss the role of molecular profiling in sarcomas in general with emphasis on selected entities with particular clinical relevance.

    Synovial sarcoma (SS) is a rare cancer and accounts for 5-10% of adult soft tissue sarcomas. Making an accurate diagnosis is difficult due to the overlapping histological features of SS with other types of sarcomas and the non-specific immunohistochemistry profile findings. Molecular testing is thus considered necessary to confirm the diagnosis since more than 90% of SS cases carry the transcript of t(X;18)(p11.2;q11.2). The purpose of this study is to diagnose SS at molecular level by testing for t(X;18) fusion-transcript expression through One-step reverse transcriptase real-time Polymerase Chain Reaction (PCR). Formalin-fixed paraffin-embedded tissue blocks of 23 cases of soft tissue sarcomas, which included 5 and 8 cases reported as SS as the primary diagnosis and differential diagnosis respectively, were retrieved from the Department of Pathology, Tengku Ampuan Afzan Hospital, Kuantan, Pahang. RNA was purified from the tissue block sections and then subjected to One-step reverse transcriptase real-time PCR using sequence specific hydrolysis probes for simultaneous detection of either SYT-SSX1 or SYT-SSX2 fusion transcript. Of the 23 cases, 4 cases were found to be positive for SYT-SSX fusion transcript in which 2 were diagnosed as SS whereas in the 2 other cases, SS was the differential diagnosis. Three cases were excluded due to failure of both amplification assays SYT-SSX and control β-2-microglobulin. The remaining 16 cases were negative for the fusion transcript. This study has shown that the application of One-Step reverse transcriptase real time PCR for the detection SYT-SSX transcript is feasible as an aid in confirming the diagnosis of synovial sarcoma.

    Background: Second malignant neoplasms may be a consequence of radiotherapy for the treatment of breast cancer. Prior studies evaluating sarcomas as second malignant neoplasms in breast cancer patients have been limited by the numbers of patients and relatively low incidence of sarcoma. Using data from the Surveillance, Epidemiology and End Results registries, we evaluated the influence of radiation therapy on the development of subsequent sarcomas in cases with primary breast cancer. Methods: Cases with primary invasive breast cancer (n=274,572) were identified in the Surveillance, Epidemiology and End Results Cancer Incidence Public-Use Database (1973-1997). The database was then queried to determine the cases developing subsequent sarcomas (n=263). Eighty-seven of these cases received radiation therapy, and 176 had no radiation therapy. The cumulative incidence of developing secondary sarcoma and the survival post developing secondary sarcoma were determined by the Kaplan-Meier method. Results: The occurrence of sarcoma was low, regardless of whether cases received or did not receive radiation therapy: 3.2 per 1,000 (SE [standard error] = 0.4) and 2.3 per 1,000 (SE=0.2) cumulative incidence at 15 years post diagnosis, respectively (p=0.001). Of the sarcomas occurring within the field of radiation, angiosarcoma accounted for 56.8%, compared to only 5.7% of angiosarcomas occurring in cases not receiving radiotherapy. The cumulative incidence of angiosarcoma at 15 years post diagnosis was 0.9 per 1,000 for cases receiving radiation (SE=0.2) and 0.1 per 1,000 for cases not receiving radiation (SE<0.1). Overall survival was poor for cases of sarcoma after breast cancer (27-35% at 5 years), but not significantly different between patients receiving or not receiving radiation therapy for their primary breast cancer. Conclusions: Radiotherapy in the treatment of breast cancer is associated with an increased risk of subsequent sarcoma, but the magnitude of this risk is

Caso clínico: Varón de 64 años, que presenta lesión en piel de mejilla derecha de un año de evolución, localización en la que presentó hace veinte años un carcinoma basocelular tratado con radioterapia. Tras descartar existencia de metástasis, se realizó exéresis de la lesión con márgenes de seguridad y reconstrucción con colgajo de Mustardé. Se complementó el tratamiento con radioterapia. Discusión: El diagnóstico es anatomopatológico, siendo fundamental descartar afectación metastásica. Para mejorar la supervivencia y disminuir su elevada tasa de recidiva, deberían tratarse de forma multidisciplinar (cirugía, radioterapia y/o quimioterapia. Conclusión: A pesar de su baja frecuencia, los sarcomas deben estar presentes en el diagnóstico diferencial de toda lesión que aparezca en zonas radiadas previamente, especialmente en la piel facial.Introduction: Sarcomas are malignant tumors that are infrequent, being rare in the head and neck.

Case report: A 64-year-old man developed a skin lesion on the right cheek one year earlier at the site where he had presented a basal cell carcinoma 20 years earlier that was treated with radiation therapy. After ruling out the existence of metastasis, the lesion was treated by surgical resection with safety margins and reconstruction with the Mustardé flap. Treatment was supplemented with radiation therapy. Discussion: The diagnosis of sarcomas is histopathologic and it is essential to rule out metastasis. To improve survival and reduce the high rate of recurrence, a multidisciplinary approach to treatment should be used (surgery

    A case of postirradiation sarcoma is described. The tumor, a malignant fibrous histiocytoma, occurred in the radiation field 11 years following postoperative external beam radiation therapy (7,000 rad) for carcinoma of the cervix. Reports of postirradiation malignant fibrous histiocytoma are rare, and the occurrence of this neoplasm following treatment for cervix cancer has not previously been described. The literature concerning postirradiation bone and soft tissue sarcomas is briefly reviewed, with special attention to malignant fibrous histiocytomas. (author)

    Histiocytic sarcoma in the liver is an extremely rare hematological malignancy. Herein, we reported the case of a 68-year-old woman who presented with characteristic wedge-shaped abnormality bounded by hepatic veins on computed tomography and magnetic resonance imaging of the liver. In the wedge-shaped area, decreased portal flow and the deposition of iron were observed. These imaging findings are consistent with intrasinusoidal tumor cell infiltration. A liver biopsy was performed, and histiocytic sarcoma was confirmed histopathologically.

    Kaposi's sarcomas (KS) are vascular lesions which usually originate from multiple sites in the mid-dermis extending to the dermis. The aetiology is unknown, but infection from human herpes virus type 8 has been suggested. Several reports of KS had come from Africa initially and from worldwide later due to the close association with HIV/AIDS. Prior to this however, KS was very frequent in Eastern Europe, Italy and the United States where it existed in an indolent form in the elderly men of Jewish ancestry. KS may also be due to iatrogenic immune suppression from chronic use of steroids, elevated degree of expression of numerous cytokines and angiogenic growth factors including TNF alpha, IL-6, bFGF, HIV-tat protein and oncostatin M. Lymphadenopathic KS involves the lymph-nodes, viscera and the gastrointestinal tract and may run a disseminated and aggressive course. We are reporting one such case in an immunocompetent male.

    Full Text Available Abstract Background Involvement of the subcutis by Kaposi sarcoma (KS occurs primarily when cutaneous KS lesions evolve into deep penetrating nodular tumors. Primary KS of the subcutaneous tissue is an exceptional manifestation of this low-grade vascular neoplasm. Case presentation We present a unique case of acquired immune deficiency syndrome (AIDS-associated KS manifesting primarily in the subcutaneous tissue of the anterior thigh in a 43-year-old male, which occurred without overlying visible skin changes or concomitant KS disease elsewhere. Radiological imaging and tissue biopsy confirmed the diagnosis of KS. Conclusion This is the first documented case of primary subcutaneous KS occurring in the setting of AIDS. The differential diagnosis of an isolated subcutaneous lesion in an human immunodeficiency virus (HIV-infected individual is broad, and requires both imaging and a histopathological diagnosis to guide appropriate therapy.

  1. Renal artery stenosis after radiotherapy for Ewing's sarcoma

    International Nuclear Information System (INIS)

    Tacconi, S.; Bieri, S.

    2008-01-01

    Background: the fact that therapeutic irradiation can induce significant stenosis in the arteries of the head, neck, and chest, as welt as in the aorta and the iliac arteries, is familiar in daily practice and well documented in the literature. By contrast, radiation-induced renal artery stenosis seems to be a less widely known complication. Patients and methods: the sudden onset of medically refractory arterial hypertension and coma in a 27-year-old man is reported, who had been treated at age 20 with chemotherapy and radiotherapy for Ewing's sarcoma in the lumbar region. This treatment had been performed at the hospital of Sion, Switzerland in 2001. Also, the relevant literature from 1965 to 2007 is reviewed to underscore various aspects of this problem and to demonstrate the clinical relevance of renal artery stenosis as a potential long-term sequela of radiotherapy. Conclusion: radiation-induced renal artery stenosis has only rarely been described in the literature, but arterial hypertension due to radiation-induced renal artery stenosis is a serious long-term sequela that can appear at a latency of up to 20 years after treatment. The paucity of reports presumably reflects the lesser frequency of radiotherapy for retroperitoneal tumors as compared to head-and-neck cancers, as well as lower awareness of the problem due to diagnostic bias in the era before CT and MRI were in routine use: at that time, carotid artery stenosis was easy to diagnose by ultrasonography, while radiation-induced renal artery stenosis, whose real incidence may well be higher, probably often went undetected. Thus, when a patient with a history of abdominal or retroperitoneal radiotherapy unexpectedly develops intractable hypertension, radiation-induced renal artery stenosis must be included in the differential diagnosis.

    Background and purpose: Radiotherapy constitutes an essential element in the multimodal therapy of Ewing's sarcoma. Compared to other sarcomas, Ewing tumors normally show a good response to radiotherapy. However, there are consistently tumors with a radioresistant phenotype, and the underlying mechanisms are not known in detail. Here we investigated the association between survivin protein expression and the radiosensitivity of Ewing's sarcoma in vitro. Material and methods: An siRNA-based knockdown approach was used to investigate the influence of survivin expression on cell proliferation, double-strand break (DSB) induction and repair, apoptosis and colony-forming ability in four Ewing's sarcoma cell lines with and without irradiation. Results: Survivin protein and mRNA were upregulated in all cell lines tested in a dose-dependent manner. As a result of survivin knockdown, STA-ET-1 cells showed reduced cell proliferation, an increased number of radiation-induced DSBs, and reduced repair. Apoptosis was increased by knockdown alone and increased further in combination with irradiation. Colony formation was significantly reduced by survivin knockdown in combination with irradiation. Conclusion: Survivin is a radiation-inducible protein in Ewing's sarcoma and its down-regulation sensitizes cells toward irradiation. Survivin knockdown in combination with radiation inhibits cell proliferation, repair, and colony formation significantly and increases apoptosis more than each single treatment alone. This might open new perspectives in the radiation treatment of Ewing's sarcoma. (orig.)

    Histiocytic sarcoma is a rare malignant neoplasm of presumed hematopoietic origin showing morphologic and immunophenotypic evidence of histiocytic differentiation. Somatic mutation importance in the pathogenesis or disease progression of histiocytic sarcoma was largely unknown. To identify somatic mutations in histiocytic sarcoma, we studied 5 histiocytic sarcomas [3 female and 2 male patients; mean age 54.8 (20-72), anatomic sites include lymph node, uterus, and pleura] and matched normal tissues from each patient as germ line controls. Somatic mutations in 50 "Hotspot" oncogenes and tumor suppressor genes were examined using next generation sequencing. Three (out of five) histiocytic sarcoma cases carried somatic mutations in BRAF. Among them, G464V [variant frequency (VF) of 43.6 %] and G466R (VF of 29.6 %) located at the P loop potentially interfere with the hydrophobic interaction between P and activating loops and ultimately activation of BRAF. Also detected was BRAF somatic mutation N581S (VF of 7.4 %), which was located at the catalytic loop of BRAF kinase domain: its role in modifying kinase activity was unclear. A similar mutational analysis was also performed on nine acute monocytic/monoblastic leukemia cases, which did not identify any BRAF somatic mutations. Our study detected several BRAF mutations in histiocytic sarcomas, which may be important in understanding the tumorigenesis of this rare neoplasm and providing mechanisms for potential therapeutical opportunities.

    To determine and compare the value of 18 F-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (FDG-PET/CT) to blind bone marrow biopsy (BMB) of the posterior iliac crest in detecting metastatic bone marrow involvement in newly diagnosed Ewing sarcoma. This retrospective study included 20 patients with newly diagnosed Ewing sarcoma who underwent pretreatment FDG-PET/CT and a total of 38 blind BMBs (two unilateral and 18 bilateral) of the posterior iliac crest. FDG-PET/CT scans were evaluated for bone marrow involvement, both in the posterior iliac crest and other sites, and compared to blind BMB results. FDG-PET/CT was positive for bone marrow involvement in 7/38 posterior iliac crests, whereas BMB was positive in 5/38 posterior iliac crests. FDG-PET/CT and BMB results in the posterior iliac crest agreed in 36/38 cases (94.7%, 95% confidence interval [CI]: 82.7-98.5%). On a patient level, FDG-PET/CT was positive for bone marrow involvement in 4/20 patients, whereas BMB of the posterior iliac crest was positive in 3/20 patients. On a patient level, FDG-PET/CT and BMB results agreed in 19/20 patients (95.0%, 95% CI: 76.4-99.1%). The only discrepancies between FDG-PET/CT and BMB were observed in two BMBs of one patient. Both BMBs in this patient were negative, whereas FDG-PET/CT indicated bilateral posterior iliac crest involvement and also extensive bone marrow involvement elsewhere. FDG-PET/CT appears to be a valuable method for metastatic bone marrow assessment in newly diagnosed Ewing sarcoma. The routine use of blind BMB of the posterior iliac crest should be reconsidered when FDG-PET/CT is available. (orig.)

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.

    In 2013 Australia introduced Wiki-based Clinical Practice Guidelines for the Management of Adult Onset Sarcoma. These guidelines utilized a customized MediaWiki software application for guideline development and are the first evidence-based guidelines for clinical management of sarcoma. This paper presents our experience with developing and implementing web-based interactive guidelines and reviews some of the challenges and lessons from adopting an evidence-based (rather than consensus-based) approach to clinical sarcoma guidelines. Digital guidelines can be easily updated with new evidence, continuously reviewed and widely disseminated. They provide an accessible method of enabling clinicians and consumers to access evidence-based clinical practice recommendations and, as evidenced by over 2000 views in the first four months after release, with 49% of those visits being from countries outside of Australia. The lessons learned have relevance to other rare cancers in addition to the international sarcoma community. PMID:25784832

    1997-01-01

    Five cases diagnosed as extraosseous Ewing's sarcoma (EES) during a 15 year period, and the relevant literature, were reviewed. The diagnosis in these cases was difficult to confirm, mainly because the distinction between the osseous form of Ewing's sarcoma (OES) and either periosteal reactions or direct tumour invasion into adjacent bone by EES was often unclear. The literature suggests that other authors have also encountered difficulties. The authors believe that many cases reported as EES are likely to have been OES. This distinction has some importance, as the two conditions are usually treated in differing ways. The following criteria are proposed for the diagnosis of primary EES: (i) no evidence of bony involvement on magnetic resonance imaging; (ii) no evidence of increased uptake in bone or periosteum adjacent to the tumour on static isotope bone scan images; (iii) a small round cell tumour with no differentiating features on light microscopy, immunochemistry or electron microscopy; and (iv) demonstration of cytoplasmic glycogen. 19 refs., 2 tabs., 6 figs

    Kaposi's sarcoma (KS) is an infectious cancer occurring most commonly in human immunodeficiency virus (HIV) positive patients and in endemic regions, such as Sub-Saharan Africa, where KS is among the top four most prevalent cancers. The cause of KS is the Kaposi's sarcoma-associated herpesvirus (KSHV, also called HHV-8), an oncogenic herpesvirus that while routinely diagnosed in developed nations, provides challenges to developing world medical providers and point-of-care detection. A major challenge in the diagnosis of KS is the existence of a number of other diseases with similar clinical presentation and histopathological features, requiring the detection of KSHV in a biopsy sample. In this work we develop an answer to this challenge by creating a multiplexed one-pot detection system for KSHV DNA and DNA from a frequently confounding disease, bacillary angiomatosis. Gold and silver nanoparticle aggregation reactions are tuned for each target and a multi-color change system is developed capable of detecting both targets down to levels between 1 nM and 2 nM. The system developed here could later be integrated with microfluidic sample processing to create a final device capable of solving the two major challenges in point-of-care KS detection.

    Full Text Available 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.O sarcoma epitelióide, primeiramente descrito por Enzinger, em 1970, é uma neoplasia de partes moles que ocorre principalmente nas extremidades distais de adolescentes e adultos jovens.

    Full Text Available Abstract Background It is not clear whether environmental exposure to dioxin affects the general population. The aim of this research is to evaluate sarcoma risk in relation to the environmental pollution caused by dioxin emitted by waste incinerators and industrial sources of airborne dioxin. The study population lives in a part of the Province of Venice (Italy, where a population-based cancer registry (Veneto Tumour Registry – RTV has been active since 1987. Methods Two hundred and five cases of visceral and extravisceral sarcoma, confirmed by microscopic examination, diagnosed from 01.01.1990 to 31.12.1996, were extracted from the RTV database. Diagnoses were revised using the actual pathology reports and clinical records. For each sarcoma case, three controls of the same age and sex were randomly selected from the population files of the Local Health Units (LHUs. The residential history of each subject, whether case or control, was reconstructed, address by address, from 1960 to the date of diagnosis. All waste incinerators and industrial sources of airborne dioxin in the Province of Venice were taken into account, as was one very large municipal waste incinerator outside the area but close to its boundaries. The Industrial Source Complex Model in Long Term mode, version 3 (ISCLT3, was used to assess the level of atmospheric dispersion.

    Background It is not clear whether environmental exposure to dioxin affects the general population. The aim of this research is to evaluate sarcoma risk in relation to the environmental pollution caused by dioxin emitted by waste incinerators and industrial sources of airborne dioxin. The study population lives in a part of the Province of Venice (Italy), where a population-based cancer registry (Veneto Tumour Registry – RTV) has been active since 1987. Methods Two hundred and five cases of visceral and extravisceral sarcoma, confirmed by microscopic examination, diagnosed from 01.01.1990 to 31.12.1996, were extracted from the RTV database. Diagnoses were revised using the actual pathology reports and clinical records. For each sarcoma case, three controls of the same age and sex were randomly selected from the population files of the Local Health Units (LHUs). The residential history of each subject, whether case or control, was reconstructed, address by address, from 1960 to the date of diagnosis. All waste incinerators and industrial sources of airborne dioxin in the Province of Venice were taken into account, as was one very large municipal waste incinerator outside the area but close to its boundaries. The Industrial Source Complex Model in Long Term mode, version 3 (ISCLT3), was used to assess the level of atmospheric dispersion. A specific value for exposure was calculated for each point (geo-referenced address) and for each calendar year; the exposure value for each subject is expressed as the average of specific time-weighted values. The analysis takes into account 172 cases and 405 controls, aged more than 14 years. Results The risk of developing a sarcoma is 3.3 times higher (95% Confidence Interval – 95% CI: 1.24 – 8.76) among subjects, both sexes, with the longest exposure period and the highest exposure level ; a significant excess of risk was also observed in women (Odds Ratio OR = 2.41, 95% CI: 1.04 – 5.59) and for cancers of the connective

    Trauma is the most common cause of death in childhood, and abusive head trauma is the most common cause of traumatic death and morbidity in infants younger than 1 year. The main differential diagnosis of abusive head trauma is accidental traumatic brain injury, which is usually witnessed. This paper also discusses more uncommon diagnoses such as congenital and acquired disorders of hemostasis, cerebral arteriovenous malformations and metabolic diseases, all of which are extremely rare. Diagnostic imaging including CT and MRI is very important for the distinction of non-accidental from accidental traumatic injury. (orig.)

    Ultrasound has revolutionized pediatric nephrology in the last decades and has a major impact on management and treatment of several children's kidneys diseases. Hydronephrosis is the most common anomaly in childhood. Progress in fetal imaging in the last years has a important impact in diagnosing congenital hydronephrosis. The current study try to establish authors opinion on problem over coming in the every day practice in pediatric nephrologist - is surgery mandatory in high grade pediatric hydronephrosis. A discussion is undergoing in the literature, following communications that high grade hydronephrosis tend spontaneously to regress in more that 65% according to Koff (2000, 2008)
