    Primary lung sarcomas are uncommon histologic types of primary lung cancer and presents a wide spectrum of clinical behaviour. Nine patients treated at Antoine Lacassagne Cancer Center between 1982 and 1995 were studied. The median age was 63 years (range, 35-73 years) and the most common histologic types were malignant fibrous histiocytoma (four) and leiomyosarcoma (three). All of them underwent surgery, six patients had a complete surgery and three patients incomplete resections. The median overall survival for all patients was 36 months. In the subgroup of patients with initial complete resection, the median survival was significantly longer (47 months) than in the subgroup of patients with incomplete resection (6 months) (Prank test). Moreover, two patients had a second complete resection for ipsilateral lung relapse and were long survivors (overall survival of 58 and 83 months, respectively). The ability to achieve a complete second surgery stress the possible benefit of an early detection of local recurrence. Because no specific symptom was linked with the local relapse, a systematic CT scan every 2 or 3 months could be required.

    The survival of Ewing sarcoma (ES) patients has improved since the 1970s but is associated with considerable future health risks. The study population consisted of long-term (> or =5-year) survivors of childhood ES diagnosed before age 21 from 1970 to 1986. Cause-specific mortality was evaluated in eligible survivors (n = 568), and subsequent malignant neoplasms, chronic health conditions, infertility, and health status were evaluated in the subset participating in the Childhood Cancer Survivor Study (n = 403). Outcomes were compared with the US population and sibling control subjects (n = 3899). Logistic, Poisson, or Cox proportional hazards models, with adjustments for sex, age, race/ethnicity, and potential intrafamily correlation, were used. Statistical tests were two-sided. Cumulative mortality of ES survivors was 25.0% (95% confidence interval [CI] = 21.1 to 28.9) 25 years after diagnosis. The all-cause standardized mortality ratio was 13.3 (95% CI = 11.2 to 15.8) overall, 23.1 (95% CI = 17.6 to 29.7) for women, and 10.0 (95% CI = 7.9 to 12.5) for men. The nonrecurrence-progression non-external cause standardized mortality ratio (subsequent non-ES malignant neoplasms and cardiac and pulmonary causes potentially attributable to ES treatment) was 8.7 (95% CI = 6.2 to 12.0). Twenty-five years after ES diagnosis, cumulative incidence of subsequent malignant neoplasms, excluding nonmelanoma skin cancers, was 9.0% (95% CI = 5.8 to 12.2). Compared with siblings, survivors had an increased risk of severe, life-threatening, or disabling chronic health conditions (relative risk = 6.0, 95% CI = 4.1 to 9.0). Survivors had lower fertility rates (women: P = .005; men: P < .001) and higher rates of moderate to extreme adverse health status (P < .001). Long-term survivors of childhood ES exhibit excess mortality and morbidity.

    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 Background. Extremity sarcoma represents a heterogeneous group of rare cancers that carries a relatively high morbidity with regards to physical function. Quality of Life (QoL as an outcome is an important consideration in this cohort. We aimed to identify the correlates of QoL in extremity sarcoma cohorts. Methods. A systematic review of the literature on extremity sarcoma in adults from five databases over the last ten years was undertaken. Results. Twelve articles were chosen and assessed for quality. Physical and social function of extremity sarcoma survivors is below that of the general population. Overall QoL scores of these patients are comparable to those of the general population. Studies that used more recently treated cohorts found that patients who had limb sparing surgery displayed superior functional outcomes over those that underwent amputations. Pain and perceiving that the cancer negatively influenced opportunities was associated with poor outcomes. Conclusion. The available literature regarding QoL in extremity sarcoma patients is heterogeneous in terms of aims and assessment tools. Results need to be interpreted in light of the improved management of extremity sarcoma in more recent patient cohorts.

    Very high levels of ionizing radiation exposure have been associated with the development of soft-tissue sarcoma. The effects of lower levels of ionizing radiation on sarcoma development are unknown. This study addressed the role of low to moderately high levels of ionizing radiation exposure in the development of soft-tissue sarcoma. Based on the Life Span Study cohort of Japanese atomic-bomb survivors, 80,180 individuals were prospectively assessed for the development of primary soft-tissue sarcoma. Colon dose in gray (Gy), the excess relative risk, and the excess absolute rate per Gy absorbed ionizing radiation dose were assessed. Subject demographic, age-specific, and survival parameters were evaluated. One hundred and four soft-tissue sarcomas were identified (mean colon dose = 0.18 Gy), associated with a 39% five-year survival rate. Mean ages at the time of the bombings and sarcoma diagnosis were 26.8 and 63.6 years, respectively. A linear dose-response model with an excess relative risk of 1.01 per Gy (95% confidence interval [CI]: 0.13 to 2.46; p = 0.019) and an excess absolute risk per Gy of 4.3 per 100,000 persons per year (95% CI: 1.1 to 8.9; p = 0.001) were noted in the development of soft-tissue sarcoma. This is one of the largest and longest studies (fifty-six years from the time of exposure to the time of follow-up) to assess ionizing radiation effects on the development of soft-tissue sarcoma. This is the first study to suggest that lower levels of ionizing radiation may be associated with the development of soft-tissue sarcoma, with exposure of 1 Gy doubling the risk of soft-tissue sarcoma development (linear dose-response). The five-year survival rate of patients with soft-tissue sarcoma in this population was much lower than that reported elsewhere.

    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.

    ECCO essential requirements for quality cancer care (ERQCC) are checklists and explanations of organisation and actions that are necessary to give high-quality care to patients who have a specific tumour type. They are written by European experts representing all disciplines involved in cancer care. ERQCC papers give oncology teams, patients, policymakers and managers an overview of the elements needed in any healthcare system to provide high quality of care throughout the patient journey. References are made to clinical guidelines and other resources where appropriate, and the focus is on care in Europe. Sarcoma: essential requirements for quality care • Sarcomas - which can be classified into soft tissue and bone sarcomas - are rare, but all rare cancers make up more than 20% of cancers in Europe, and there are substantial inequalities in access to high-quality care. Sarcomas, of which there are many subtypes, comprise a particularly complex and demanding challenge for healthcare systems and providers. This paper presents essential requirements for quality cancer care of soft tissue sarcomas in adults and bone sarcomas. • High-quality care must only be carried out in specialised sarcoma centres (including paediatric cancer centres) which have both a core multidisciplinary team and an extended team of allied professionals, and which are subject to quality and audit procedures. Access to such units is far from universal in all European countries. • It is essential that, to meet European aspirations for high-quality comprehensive cancer control, healthcare organisations implement the requirements in this paper, paying particular attention to multidisciplinarity and patient-centred pathways from diagnosis and follow-up, to treatment, to improve survival and quality of life for patients. Taken together, the information presented in this paper provides a comprehensive description of the essential requirements for establishing a high-quality service for soft

    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.

  12. Sarcoma risk after radiation exposure

    2012-10-01

    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 (

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.

    Retroperitoneal sarcomas are rare tumors, representing only 15% of all sarcomas. The mainstay of therapy is surgical resection with negative margins. However, this is challenging because of the late presentation of many of these tumors and involvement with adjacent structures. Decisions on radiation therapy and chemotherapy should be made in a multidisciplinary setting at a tertiary referral center.

    2013-01-01

    Kaposi's sarcoma-associated herpesvirus (KSHV), the etiologic agent of Kaposi's sarcoma (KS), is present in the predominant tumor cells of KS, the spindle cells. Spindle cells express markers of lymphatic endothelium and, interestingly, KSHV infection of blood endothelial cells reprograms them to a lymphatic endothelial cell phenotype. KSHV-induced reprogramming requires the activation of STAT3 and phosphatidylinositol 3 (PI3)/AKT through the activation of cellular receptor gp130. Importantly, KSHV-induced reprogramming is specific to endothelial cells, indicating that there are additional host genes that are differentially regulated during KSHV infection of endothelial cells that contribute to lymphatic reprogramming. We found that the transcription factor Ets-1 is highly expressed in KS spindle cells and is upregulated during KSHV infection of endothelial cells in culture. The KSHV latent vFLIP gene is sufficient to induce Ets-1 expression in an NF-κB-dependent fashion. Ets-1 is required for KSHV-induced expression of VEGFR3, a lymphatic endothelial-cell-specific receptor important for lymphangiogenesis, and Ets-1 activates the promoter of VEGFR3. Ets-1 knockdown does not alter the expression of another lymphatic-specific gene, the podoplanin gene, but does inhibit the expression of VEGFR3 in uninfected lymphatic endothelium, indicating that Ets-1 is a novel cellular regulator of VEGFR3 expression. Knockdown of Ets-1 affects the ability of KSHV-infected cells to display angiogenic phenotypes, indicating that Ets-1 plays a role in KSHV activation of endothelial cells during latent KSHV infection. Thus, Ets-1 is a novel regulator of VEGFR3 and is involved in the induction of angiogenic phenotypes by KSHV. PMID:23552426

  7. Postradiation sarcoma of bone: review of 78 Mayo Clinic cases

    Energy Technology Data Exchange (ETDEWEB)

    1981-05-01

    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.

    Pulmonary metastasectomy for sarcoma is a widely accepted practice. Nevertheless, no previous studies has been reported the outcomes following metastasectomy compared with chemotherapy for patients with resectable and isolated pulmonary metastases. Our aim is to compare these modalities for the subset of patients with resectable metastases. Furthermore, the outcomes for patients with unresectable lung metastases are reported. Sarcoma patients with isolated lung metastases were identified and their computed axial tomography scans were reviewed by a thoracic surgeons' committee. Patients were divided into three groups: A: patients with resectable metastases treated with metastasectomy (n=29), B: patients with resectable metastases who received systemic therapy (n=17) and C: patients with unresectable metastases (n=25). Survival outcomes were plotted and compared through log-rank test for osteosarcoma and non-osteosarcoma patients. Seventy-one patients (32 with osteosarcoma and 39 with non-osteosarcoma) were eligible. Progression-free survival (PFS) was superior in patients who belonged to Group A compared with Groups B and C (8.0, 4.3 and 2.2 months, respectively, P=0.0002). Furthermore, overall survival (OS) was superior in patients who belonged to Group A compared with Groups B and C (39.6, 20.0 and 7.8 months, respectively, Posteosarcoma patients showed superior PFS and OS for Group A vs B (median PFS 21.6 and 3.65 months, respectively, P=0.011 and median OS 34.0 and 12.4 months, respectively, P=0.0044). For non-osteosarcoma patients, there were no such significant survival differences between Groups A and B. Overall, patients who belonged to Group A had significantly lower mean percentage of their follow-up time spent admitted at hospital, and a trend towards lower requirements for home oxygen therapy. Pulmonary metastasectomy is associated with improved survival of osteosarcoma patients with resectable lung metastases. For non-osteosarcoma patients, the survival

  13. Attenuation of the suppressive activity of cellular splicing factor SRSF3 by Kaposi sarcoma-associated herpesvirus ORF57 protein is required for RNA splicing.

    Science.gov (United States)

    Majerciak, Vladimir; Lu, Mathew; Li, Xiaofan; Zheng, Zhi-Ming

    2014-11-01

    Kaposi sarcoma-associated herpesvirus (KSHV) ORF57 is a multifunctional post-transcriptional regulator essential for viral gene expression during KSHV lytic infection. ORF57 requires interactions with various cellular proteins for its function. Here, we identified serine/arginine-rich splicing factor 3 (SRSF3, formerly known as SRp20) as a cellular cofactor involved in ORF57-mediated splicing of KSHV K8β RNA. In the absence of ORF57, SRSF3 binds to a suboptimal K8β intron and inhibits K8β splicing. Knockdown of SRSF3 promotes K8β splicing, mimicking the effect of ORF57. The N-terminal half of ORF57 binds to the RNA recognition motif of SRSF3, which prevents SRSF3 from associating with the K8β intron RNA and therefore attenuates the suppressive effect of SRSF3 on K8β splicing. ORF57 also promotes splicing of heterologous non-KSHV transcripts that are negatively regulated by SRSF3, indicating that the effect of ORF57 on SRSF3 activity is independent of RNA target. SPEN proteins, previously identified as ORF57-interacting partners, suppress ORF57 splicing activity by displacing ORF57 from SRSF3-RNA complexes. In summary, we have identified modulation of SRSF3 activity as the molecular mechanism by which ORF57 promotes RNA splicing.

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. Different abnormalities in sarcoma could be divided by tumor subtype or by the molecular or pathway abnormality. However, some existing drugs or drugs in development may interfere with or alter more than one of the presented pathways.

  15. Low pH is required for avian sarcoma and leukosis virus Env-dependent viral penetration into the cytosol and not for viral uncoating.

    A novel entry mechanism has been proposed for the avian sarcoma and leukosis virus (ASLV), whereby interaction with specific cell surface receptors activates or primes the viral envelope glycoprotein (Env), rendering it sensitive to subsequent low-pH-dependent fusion triggering in acidic intracellular organelles. However, ASLV fusion seems to proceed to a lipid mixing stage at neutral pH, leading to the suggestion that low pH might instead be required for a later stage of viral entry such as uncoating (L. J. Earp, S. E. Delos, R. C. Netter, P. Bates, and J. M. White. J. Virol. 77:3058-3066, 2003). To address this possibility, hybrid virus particles were generated with the core of human immunodeficiency virus type 1 (HIV-1), a known pH-independent virus, and with subgroups A or B ASLV Env proteins. Infection of cells by these pseudotyped virions was blocked by lysosomotropic agents, as judged by inhibition of HIV-1 DNA synthesis. Furthermore, by using HIV-1 cores that contain a Vpr-beta-lactamase fusion protein (Vpr-BlaM) to monitor viral penetration into the cytosol, we demonstrated that virions bearing ASLV Env, but not HIV-1 Env, enter the cytosol in a low-pH-dependent manner. This effect was independent of the presence of the cytoplasmic tail of ASLV Env. These studies provide strong support for the model, indicating that low pH is required for ASLV Env-dependent viral penetration into the cytosol and not for viral uncoating.

    2010-01-01

    Full Text Available Ewing′s sarcoma constitutes three per cent of all pediatric malignancies. Ewing′s sarcoma has generally been more responsive to chemotherapy than adult-type sarcomas, and chemotherapy is now recommended for all patients with this disease. It is essential to integrate local control measures in the form of surgery and/or radiotherapy at the appropriate time, along with chemotherapy to eradicate the disease. This approach has improved the survival substantially to the tune of 70% in localized disease, although outcome for metastatic disease remains dismal. Newer therapeutic approaches are required to improve outcome for metastatic and recurrent or refractory Ewing′s sarcoma in organized co-operative group trials.

    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.

    Full Text Available Extraosseous osteogenic sarcoma is a very rare malignant neoplasm. Out of the more than 400 cases of soft tissue sarcomas on file in our hospital, only 2 were extraosseous osteogenic sarcomas. Both were situated in the thigh. The first case was initially diagnosed as a hematoma and treated by marginal excision. The diagnosis of high-grade osteosarcoma primarily arising in soft tissue was made from histopathologic examination. Radiotherapy of 60 Gy in 30 fractions was given postoperatively. The second patient, primarily diagnosed as having a soft tissue sarcoma, was treated by wide excision. The final pathologic report was high-grade extraosseous osteogenic sarcoma. Adjuvant chemotherapy was given postoperatively. Both patients are alive without local recurrence and distant metastasis at postoperative 90-month and 107-month follow-up, respectively.

    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.

    Lytic replication of Kaposi's sarcoma-associated herpesvirus (KSHV) promotes the progression of Kaposi's sarcoma (KS), a dominant malignancy in patients with AIDS. While 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced KSHV reactivation from latency is mediated by the protein kinase C delta and MEK/ERK mitogen-activated protein kinase (MAPK) pathways, we have recently shown that the MEK/ERK, JNK and p38 MAPK pathways modulate KSHV lytic replication during productive primary infection of human umbilical vein endothelial cells [Pan, H., Xie, J., Ye, F., Gao, S.J., 2006. Modulation of Kaposi's sarcoma-associated herpesvirus infection and replication by MEK/ERK, JNK, and p38 multiple mitogen-activated protein kinase pathways during primary infection. J. Virol. 80 (11), 5371-5382]. Here, we report that, besides the MEK/ERK pathway, the JNK and p38 MAPK pathways also mediate TPA-induced KSHV reactivation from latency. The MEK/ERK, JNK and p38 MAPK pathways were constitutively activated in latent KSHV-infected BCBL-1 cells. TPA treatment enhanced the levels of activated ERK and p38 but not those of activated JNK. Inhibitors of all three MAPK pathways reduced TPA-induced production of KSHV infectious virions in BCBL-1 cells in a dose-dependent fashion. The inhibitors blocked KSHV lytic replication at the early stage(s) of reactivation, and reduced the expression of viral lytic genes including RTA, a key immediate-early transactivator of viral lytic replication. Activation of MAPK pathways was necessary and sufficient for activating the promoter of RTA. Furthermore, we showed that the activation of RTA promoter by MAPK pathways was mediated by their downstream target AP-1. Together, these findings suggest that MAPK pathways might have general roles in regulating the life cycle of KSHV by mediating both viral infection and switch from viral latency to lytic replication.

    Ectopic hamartomatous thymoma (EHT) is an extremely rare benign tumor. EHTs are difficult to differentiate from sarcomas, especially synovial sarcomas. We encountered two cases of EHT that were referred from other hospitals because sarcoma was suspected. In these cases, fusion gene detection via polymerase chain reaction or fluorescence in situ hybridization was useful for differentiating EHT from synovial sarcoma. EHT requires accurate diagnosis before surgery to avoid excessive treatment. Both tumor location and the presence of fat inside the tumor are important imaging findings for EHT, and confirmation of spindle cells, epithelial cells, and mature adipose cells in the tumor is an important pathological finding. It is important to exclude synovial sarcoma from the differential diagnosis via fusion gene analysis. PMID:28168073

    Full Text Available Advances in systemic therapy for sarcoma have produced, over the last two decades, relatively short-term benefits for the majority of patient. Among the novel biologic therapeutics that will likely increase our ability to cure human cancer in the years to come, immunotherapy is one of the most promising approaches. While past attempts to use immunotherapy have failed to dramatically shift the paradigm of care for the treatment of patients with sarcoma, major advances in basic and translational research have resulted, in more recent years, in clinical trial activity that is now beginning to generate promising results. However, to move from “proof of principle” to large scale clinical applicability, we need well-designed, multi-institutional clinical trials, along with continuous laboratory research to explore further the immunological characteristics of individual sarcoma subtypes and the consequent tailoring of therapy.

    Sarcoma of the breast represents only 0.2-1% of all mammary malignancies. This study reports 5 such cases, including 2 osteosarcomas, 1 fibro-, 1 lipo-, and 1 malignant fibrous sarcoma. The treatment used was mastectomy in 3 cases with excision of axillary lymph nodes. The remaining 2 patients were treated by simple mastectomy whereby 1 of these received a immediate reconstruction with a prosthesis. 1 patient demonstrated local recurrence and died. The remaining 4 patients did not develop neither metastases nor local recurrence and are still alive after an observing period between 12 months up to 17 years. Today, first-line treatment is wide local excision or simple mastectomy. Excision of the axillary lymphatics, adjuvant radiotherapy, and chemotherapy have been disappointing in the treatment of breast sarcoma.

    Nowadays, Kaposi sarcoma is a multidisciplinary condition, not only observed by dermatologists. Since the HIV epidemic in the 80s and 90s of the last century, more insight into the aetiology of Kaposi sarcoma has been acquired. However, this sarcoma had already been described in 1872 by a Hungarian dermatologist named Moritz Kaposi (1832-1902). Kaposi described the entity as 'idiopathic multiple pigmented sarcoma of the skin'. This entity was an extraordinary diagnosis at that time, mostly observed in Jewish or Mediterranean men. In 1912, 10 years after the death of Moritz Kaposi, the entity name was changed to Kaposi sarcoma.

    Full Text Available Medulloblastoma, astrocytoma, and ependymoma represent the most common infratentorial tumors in childhood, while Ewing sarcomas in that localization are extremely rare. A large left infratentorial space-occupying lesion was diagnosed in a 12-year-old girl with signs of increased intracranial pressure. Following total tumor resection, histological and molecular examination revealed Ewing sarcoma with rearranged EWSR-1 gene. The patient achieved complete remission following adjuvant chemotherapy and radiotherapy according to Euro-EWING 2008 treatment protocol. Intracranial Ewing sarcoma, although rare, should be an important differential diagnosis of intracranial tumors in childhood which requires aggressive multimodal treatment.

    The superhelical properties of chromosomal DNA from cells of a mouse sarcoma were investigated in neutral sucrose gradients containing ethidium bromide. Removal of negative supercoiling from the DNA of the sarcoma cells required a substantially higher dye concentration than was necessary in the case of DNA from cultured mouse fibroblasts. The calculated value of the mean superhelical density in malignant cells (sigma = -0.14) appears abnormally high compared with the value (sigma = -0.09) obtained for DNA of mouse fibroblasts. Chromosomal DNA from mouse sarcoma cells is therefore concluded to be highly deficient in helical turns.

    Full Text Available Sarcomas are rare malignant tumors affecting all age groups. They are typically classified according to their resemblance to corresponding normal tissue. Their heterogeneous features, for example in terms of disease-driving genetic aberrations and body location, complicate both disease classification and development of novel treatment regimens. Many years of failure of improved patient outcome in clinical trials has lead to the conclusion that novel targeted therapies are likely needed in combination with current multimodality regimens. Sarcomas have not, in contrast to the common carcinomas, been the subject for larger systematic studies on how tumor behavior relates to characteristics of the tumor microenvironment. There is consequently an urgent need for identifying suitable molecular targets, not only in tumor cells, but also in the tumor microenvironment. This review discusses preclinical and clinical data about potential molecular targets in sarcomas. Studies on targeted therapies involving the tumor microenvironment are prioritized. A greater understanding of the biological context is expected to facilitate more successful design of future clinical trials in sarcoma.

    RNA helicase DDX3 has oncogenic activity in breast and lung cancers and is required for translation of complex mRNA transcripts, including those encoding key cell-cycle regulatory proteins. We sought to determine the expression and function of DDX3 in sarcoma cells, and to investigate the antitumor activity of a novel small molecule DDX3 inhibitor, RK-33. Utilizing various sarcoma cell lines, xenografts and human tissue microarrays, we measured DDX3 expression at the mRNA and protein levels, and evaluated cytotoxicity of RK-33 in sarcoma cell lines. To study the role of DDX3 in Ewing sarcoma, we generated stable DDX3-knockdown Ewing sarcoma cell lines using DDX3-specific small hairpin RNA (shRNA), and assessed oncogenic activity. DDX3-knockdown and RK-33-treated Ewing sarcoma cells were compared with wild-type cells using an isobaric mass-tag quantitative proteomics approach to identify target proteins impacted by DDX3 inhibition. Overall, we found high expression of DDX3 in numerous human sarcoma subtypes compared with non-malignant mesenchymal cells, and knockdown of DDX3 by RNA interference inhibited oncogenic activity in Ewing sarcoma cells. Treatment with RK-33 was preferentially cytotoxic to sarcoma cells, including chemotherapy-resistant Ewing sarcoma stem cells, while sparing non-malignant cells. Sensitivity to RK-33 correlated with DDX3 protein expression. Growth of human Ewing sarcoma xenografts expressing high DDX3 was inhibited by RK-33 treatment in mice, without overt toxicity. DDX3 inhibition altered the Ewing sarcoma cellular proteome, especially proteins involved in DNA replication, mRNA translation and proteasome function. These data support further investigation of the role of DDX3 in sarcomas, advancement of RK-33 to Ewing sarcoma clinical trials and development of RNA helicase inhibition as a novel anti-neoplastic strategy.

    Full Text Available Myxoinflammatory fibroblastic sarcoma is a low grade sarcoma that is composed of a mixed inflammatory infiltrate along with spindled, epithelioid and bizarre appearing cells in a background of hyaline and myxoid zones. Seen affecting the distal extremities commonly, with an equal sex predilection, these tumors are rare and require an extensive immunohistochemical work up for proper diagnosis. They have a tendency to recur.

  8. Binding of cellular export factor REF/Aly by Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 protein is not required for efficient KSHV lytic replication.

    2012-09-01

    Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 protein is expressed early during lytic KSHV replication, enhances expression of many KSHV genes, and is essential for virus production. ORF57 is a member of a family of proteins conserved among all human and many animal herpesviruses that are multifunctional regulators of gene expression and act posttranscriptionally to increase accumulation of their target mRNAs. The mechanism of ORF57 action is complex and may involve effects on mRNA transcription, stability, and export. ORF57 directly binds to REF/Aly, a cellular RNA-binding protein component of the TREX complex that mediates RNA transcription and export. We analyzed the effects of an ORF57 mutation known to abrogate REF/Aly binding and demonstrate that the REF-binding mutant is impaired in activation of viral mRNAs and noncoding RNAs confined to the nucleus. Although the inability to bind REF leads to decreased ORF57 activity in enhancing gene expression, there is no demonstrable effect on nuclear export of viral mRNA or the ability of ORF57 to support KSHV replication and virus production. These data indicate that REF/Aly-ORF57 interaction is not essential for KSHV lytic replication but may contribute to target RNA stability independent of effects on RNA export, suggesting a novel role for REF/Aly in viral RNA metabolism.

    Primary hepatic sarcomas are rare tumors that are difficult to diagnose clinically. Different primary hepatic sarcomas may have different clinical, morphologic, and radiological features. In this pictorial review, we summarized computed tomography (CT) findings of some relatively common types of hepatic sarcomas, including angiosarcoma, epithelioid hemangioendothelioma (EHE), liposarcoma, undifferentiated embryonal sarcoma (UES), leiomyosarcoma, malignant fibrous histiocytoma (MFH), and carcinosarcoma (including cystadenocarcinosarcoma). To our knowledge, hepatic cystadenocarcinosarcoma has not been described in the English literature. The CT findings in our case are similar to that of cystadenocarcinoma, a huge, multilocular cystic mass with a large mural nodule and solid portion. The advent of CT has allowed earlier detection of primary hepatic sarcomas as well as more accurate diagnosis and characterization. In addition, we briefly discuss the MRI findings and diagnostic value of primary hepatic sarcomas. (orig.)

    There has been a virtual explosion of information relating to the biology of sarcomas with which we as orthopaedists deal. Much more is yet to be learned. These findings will teach us more about the etiology of these tumors. More important, the findings will alter the way in which these tumors are treated. It is unlikely that we will continue to treat osteosarcoma or Ewing's sarcoma patients with currently available drug regimens and surgery or make treatment decisions based on the histologic classification of tumors we know today. If we are to remain active in the management of these patients we must be aware of the findings as they occur. That will ensure both that we remain the primary caretakers of these patients, and that we will continue to be stimulated intellectually by these intriguing scientific investigations.

    2016-02-07

    In 2013 there were 94,770 new cancer patients reported in Hungary. Synovial sarcoma accounts for 0.05-0.1% of all cancers and, therefore its incidence is predicted to be 47-94 patients/year in Hungary. The authors report the history of a 18-year-old man who was operated on a right upper abdominal wall tumor with R1 resection. During the next 5 months the tumor grew up to 8 cm in largest diameter. Histology revealed monophasic synovial sarcoma. Immunohistochemistry showed bcl2, focal CD99 and high molecular weight cytokeratin positivity, while smooth muscle actin, S100 and CD34 immunostainings were negative. Becose of this reoperation was not possible, curative six cycles of doxorubicine and ifosfamide with granulocyte colony stimulating factor support and 60 Gy radiotherapy was given to the tumor bed. After these treatments computed tomography scan was negative and the patient attended regular imaging every 3 months. At the age of 20 years the patient developed two neoplastic lesions in the surgical scar measuring 10 mm and 45 × 10 mm in size. R0 resection, partial rib resection and abdominal wall reconstruction were performed. Histology confirmed residual monophasic synovial sarcoma. Radiotherapy was not given because of a risk of intestinal wall perforation. Staging positron emission tomography-computed tomography proved to be negative. At the age of 22 years magnetic resonance imaging scans indicated no tumor recurrence, but after one month a rapidly growing tumorous lesion was found on ultrasound in the surgical scar measuring 20 × 20 × 12 mm in size. Cytology confirmed local recurrence and fluorescence in situ hibridization indicated t(x;18). R0 exstirpation and partial mesh resection were performed and histology showed the same monophasic synovial sarcoma. Because of the presence of vascular invasion and a close resection margin (1 mm) the patient underwent 3 cycles of adjuvant chemotherapy (doxorubicine and ifosfamide) with granulocyte colony stimulating

  18. Immediate versus Delayed Sarcoma Reconstruction: Impact on Outcomes

    2016-01-01

    Full Text Available Background. Sarcoma is a rare malignancy, and more recent management algorithms emphasize a multidisciplinary approach and limb salvage, which has resulted in an increase in overall survival and limb preservation. However, limb salvage has resulted in a higher rate of wound complications. Objective. To compare the complications between immediate and delayed (>three weeks reconstruction in the multidisciplinary limb salvage sarcoma patient population. Methods. A ten-year retrospective review of patients who underwent sarcoma resection was performed. The outcome of interest was wound complication in the postoperative period based on timing of reconstruction. We defined infection as any infection requiring intravenous antibiotics, partial flap failure as any flap requiring a debridement or revision, hematoma/seroma as any hematoma/seroma requiring drainage, and wound dehiscence as a wound that was not completely intact by three weeks postoperatively. Results. 70 (17 delayed, 53 immediate patients who underwent sarcoma resection and reconstruction met the inclusion criteria. Delayed reconstruction significantly increased the incidence of postoperative wound infection and wound dehiscence. There was no difference in partial or total flap loss, hematoma, or seroma between the two groups. Discussion and Conclusion. Immediate reconstruction results in decreased wound complications may reduce the morbidity associated with multidisciplinary treatment in the limb salvage sarcoma patient.

    Full Text Available PURPOSE: Although functional differences have been described between patients with lower extremity bone sarcoma with amputation and limb preservation surgery, differences have not clearly been shown between the two groups related to quality of life. The aim of the study was to determine if there is a difference in overall quality of life in lower extremity bone sarcoma survivors related to whether they had an amputation or a limb preservation procedure. PATIENTS AND METHODS: Eighty-two long-term survivors of lower extremity bone sarcoma were studied to make a comparison of the overall quality of life, pain assessment and psychological evaluations in limb preservation and amputation patients. Forty-eight patients with limb preservation and thirty-four patients with amputations were enrolled in the study. Validated psychometric measures including the Quality of Life Questionnaire, the Minnesota Multiphasic Personality Inventory and visual analog scales were utilized.RESULTS: The overall quality of life of patients with limb preservation was significantly higher than patients with amputation (p-value < 0.01. Significant differences were noted in the categories of material well being, job satisfiers and occupational relations. CONCLUSION: The overall quality of life of patients with limb preservation appears to be better than for those patients with amputation based on the quality of life questionnaire in patients surviving lower extremity bone sarcoma. Further analysis needs to verify the results and focus on the categories that significantly affect the overall quality of life.

    The authors describe a case of myeloid sarcoma of the orbit in a pediatric patient. An 8-month-old male infant presented to the ophthalmology clinic with a left orbital mass, which had been increasing in size over the previous 2 months. The mass was initially diagnosed at another clinic as an infantile hemangioma, and had been treated with a topical formulation of timolol. In the ophthalmology clinic, orbital magnetic resonance imaging showed a solid enhancing mass. A biopsy was performed, and histopathology revealed myeloid sarcoma. The disease responded well to a standard chemotherapy regimen. Myeloid sarcoma is a rare, extra-medullary presentation that can occur as an isolated tumor, concurrently with or at relapse of acute myeloid leukemia. Because few cases of myeloid sarcoma in the orbit have been reported, this case report aids in the management of myeloid sarcoma in pediatric patients. The report describes an 8-month-old male infant, the youngest patient to develop myeloid sarcoma without preexisting acute myeloid leukemia. [J Pediatr Ophthalmol Strabismus. 2016;53:e64-e68.].

    Science.gov (United States)

    2005-03-01

    The entity and nosology of pleomorphic malignant fibrous histiocytoma (MFH) is still ambiguous. The actual WHO-Classification uses pleomorphic malignant fibrous histiocytoma (MFH) and pleomorphic sarcoma NOS (not otherwise specified) synonymously. On the other hand text and illustrations convey the impression, that these tumors also could be pleomorphic lipo-, leio- or rhabdomyosarcomas etc. It would have been more informative to emphasize, that with the above mentioned specific sarcoma types MFH-like appearance may occur. Furthermore it would have been more up to date to consider pleomorphic sarcomas NOS as pleomorphic fibrosarcomas and include them in the chapter of fibroblastic and myofibroblastic tumors. This concept already has been carried out for the former myxoid variant of MFH, nowadays preferentially called myxofibrosarcoma. There is controversial discussion about the clinical significance of exact typing of pleomorphic sarcomas. Problems may also occur due to the lack of standards, which degree of desmin expression signifies leiomyosarcoma or just indicates myofibroblasts in MFH. The requirement of exclusion of other tumor-types before diagnosing pleomorphic fibrosarcoma still remains obligatory. After verification of the diagnosis pleomorphic sarcoma NOS or pleomorphic fibrosarcoma, grading e.g. according to criteria of the FFCCS can be carried out. Most cases of pleomorphic fibrosarcoma will qualify as high grade malignant.

    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.

    Full Text Available Primary lung sarcoma is a very rare malignant tumor, accounting for less than 0.5% of all lung tumors. We describe the case of a 50-year-old man who presented with primary pulmonary sarcoma. X-ray chest and thoracic computed tomography (CT revealed a 40 mm Χ 60 mm mass in the right upper lobe. Biopsy was reported as fusiform sarcoma. Extensive clinical examination, followed by full body CT scan was performed to exclude primary synovial sarcoma located peripherally and distant metastases. Hence, surgical excision was planned after three cycles of chemotherapy, but the patient died after the second cycle. Because a sarcoma of the lung is rare, data regarding its natural history and published cases are limited. Further investigation and data collection are required to optimize the treatment of this group of rare and aggressive tumors.

    Full Text Available A 15-yr old boy presented with low backache for 4 months associated with weakness of left lower limb. MRI of lumbosacral spine showed a sacral lesion with intraspinal and presacral soft tissue extension with neural compression. A diagnosis of tuberculosis was considered in the view of high prevalence in this part of the world, however biopsy revealed Ewing's sarcoma. Ewing's tumor of sacrum is rare, but should be suspected in low backache in children. Differential diagnosis for a sacral lesion includes tuberculosis, pyogenic osteomyelitis, lymphoma, chordoma, osteosarcoma and Ewing's sarcoma. MRI is sensitive in detecting these lesions but is nonspecific requiring histopathological examination for confirmation.

    Bradley J. Petek

    2015-02-01

    Full Text Available Soft tissue sarcomas are a group of rare tumors derived from mesenchymal tissue, accounting for about 1% of adult cancers. There are over 60 different histological subtypes, each with their own unique biological behavior and response to systemic therapy. The outcome for patients with metastatic soft tissue sarcoma is poor with few available systemic treatment options. For decades, the mainstay of management has consisted of doxorubicin with or without ifosfamide. Trabectedin is a synthetic agent derived from the Caribbean tunicate, Ecteinascidia turbinata. This drug has a number of potential mechanisms of action, including binding the DNA minor groove, interfering with DNA repair pathways and the cell cycle, as well as interacting with transcription factors. Several phase II trials have shown that trabectedin has activity in anthracycline and alkylating agent-resistant soft tissue sarcoma and suggest use in the second- and third-line setting. More recently, trabectedin has shown similar progression-free survival to doxorubicin in the first-line setting and significant activity in liposarcoma and leiomyosarcoma subtypes. Trabectedin has shown a favorable toxicity profile and has been approved in over 70 countries for the treatment of metastatic soft tissue sarcoma. This manuscript will review the development of trabectedin in soft tissue sarcomas.

    Full Text Available Ernest K Amankwah,1 Anthony P Conley,2 Damon R Reed2 1Department of Cancer Epidemiology, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA; 2Sarcoma Department, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA Abstract: Sarcomas are cancers arising from the mesenchymal layer that affect children, adolescents, young adults, and adults. Although most sarcomas are localized, many display a remarkable predilection for metastasis to the lungs, liver, bones, subcutaneous tissue, and lymph nodes. Additionally, many sarcoma patients presenting initially with localized disease may relapse at metastatic sites. While localized sarcomas can often be cured through surgery and often radiation, controversies exist over optimal management of patients with metastatic sarcoma. Combinations of chemotherapy are the most effective in many settings, and many promising new agents are under active investigation or are being explored in preclinical models. Metastatic sarcomas are excellent candidates for novel approaches with additional agents as they have demonstrated chemosensitivity and affect a portion of the population that is motivated toward curative therapy. In this paper, we provide an overview on the common sarcomas of childhood (rhabdomyosarcoma, adolescence, and young adults (osteosarcoma, Ewing sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor and older adults (leiomyosarcoma, liposarcoma, and undifferentiated high grade sarcoma in terms of the epidemiology, current therapy, promising therapeutic directions and outcome with a focus on metastatic disease. Potential advances in terms of promising therapy and biologic insights may lead to more effective and safer therapies; however, more clinical trials and research are needed for patients with metastatic sarcoma.

    Carrascosa, R; Alfageme, F; Roustán, G; Suarez, M D

    2016-05-01

    The use of ultrasound imaging has recently been increasing in numerous dermatologic diseases. This noninvasive technique provides additional details on the structure and vascularization of skin lesions. Kaposi sarcoma is a vascular tumor that typically arises in the skin and mucosas. It can spread to lymph nodes and internal organs. We performed B-mode and color Doppler ultrasound studies in 3 patients with a clinical diagnosis of Kaposi sarcoma confirmed by histological examination. We found differences in the ultrasound pattern between nodular and plaque lesions, in both B-mode and color Doppler. We believe that skin ultrasound imaging could be a useful technique for studying cutaneous Kaposi sarcoma, providing additional information on the structural and vascular characteristics of the lesion.

    Mast cell sarcoma is a disorder that results in abnormal mast cells as identified by morphology, special stains, and in some publications, c-kit mutation analysis. It affects animal species such as canines more commonly than humans. In humans it is a very rare condition, with variable clinical presentation. There is no standard therapy for the disorder. It can affect any age group. It is occasionally associated with systemic mastocytosis and/or urticaria pigmentosa. The prognosis of mast cell sarcoma in published literature is very poor in humans.

    Although prognosis in patients with localized osteosarcoma has been dramatically improved by the introduction of multiple chemotherapy agents known as combination chemotherapy, there is growing concern about the development of secondary malignant neoplasms. We report the case of a 13-year-old girl in whom the diagnosis of Ewing sarcoma of bone localized on the shaft of left femur was made 2 years after successful treatment without radiotherapy for osteosarcoma of right proximal femur. EWS-FLI1 fusion gene was detected by reverse transcriptase-polymerase chain reaction. To our knowledge, this is the first case with Ewing sarcoma of the bone as a secondary malignant neoplasm developed in osteosarcoma survivor. We collected 15 cases, included this case, with secondary Ewing sarcoma family of tumor by utilizing the PubMed search and might consider the causes of this secondary cancer.

  7. Some musculo-skeletal sequelae in cancer survivors.

    Science.gov (United States)

    Aksnes, Liv Hege; Bruland, Øyvind Sverre

    2007-01-01

    This paper deals with some of the musculo-skeletal complication that can occur after cancer treatment. In particular, we focus on Cancer Treatment Induced Bone Loss (CTIBL) and the musculo-skeletal complications that can occur in patients treated for extremity sarcoma. In addition we discuss peripheral neuropathy, musculo-skeletal pain and briefly mention some of the complications related to radiotherapy. CTIBL is mostly studied in breast cancer and prostate cancer survivors. The cause in these groups is mainly due to treatment induced hypogonadism. Other causes of CTIBL are indirect or direct cause of chemotherapy, physical inactivity and inadequate intake of vitamin D and calcium. Treatment of CTIBL consists of diet and lifestyle changes and pharmacological intervention. Extremity bone sarcomas constitute a special group since they often experience mutilating surgery and heavy combination chemotherapy. The treatment results in worse function than the normal population and the amputated usually have lower physical functioning than patients treated with limb sparing surgery (LSS). However, most studies fail to show differences in quality of life between the amputated and LSS. Most of the studies performed on musculo-skeletal sequelae have been done on survivors of childhood cancer, breast cancer or prostate cancer. More studies among the other cancer groups are needed to reveal the extent and prevalence of these complications.

    This article is based on data drawn from 90 Victoria Police operational files covering the period 2004-2008. Several thematic responses by sexual assault survivors are described as forming a master narrative of "identity shock." It is argued that the "minor/serious" sexual assault legal distinction is meaningless to survivors and conceals a shared felt experience. It is also argued that sexual assault is fundamentally a "public issue" of betrayal of citizen trust--not just a collection of "private troubles"--and that effective resolutions require more than individualized therapeutic and criminal justice measures.

    2012-01-01

    Despite recent advances in our understanding of pathogenic mechanisms involved, the true nature of Kaposi sarcoma remains an enigma. Four clinical variants have been described for the disease, differing in natural history, site of predilection, and prognosis. All forms of Kaposi sarcoma may manifest in the oral cavity and Kaposi sarcoma-associated virus appears essential to development of all clinical variants. The spectrum of therapeutic strategies is broad and selection of appropriate intervention mandates a thorough understanding of disease spread and the patient's symptomatology, as well as risks and benefits of therapy. This article provides an overview of epidemiology, subtypes, clinical course, pathogenesis, and management strategies for Kaposi sarcoma.

    Ladra, Matthew M.; Yock, Torunn I., E-mail: tyock@partners.org [Department of Radiation Oncology, Massachusetts General Hospital, Boston, MA 02114 (United States)

    2014-01-14

    Pediatric sarcomas represent a distinct group of pathologies, with approximately 900 new cases per year in the United States alone. Radiotherapy plays an integral role in the local control of these tumors, which often arise adjacent to critical structures and growing organs. The physical properties of proton beam radiotherapy provide a distinct advantage over standard photon radiation by eliminating excess dose deposited beyond the target volume, thereby reducing both the dose of radiation delivered to non-target structures as well as the total radiation dose delivered to a patient. Dosimetric studies comparing proton plans to IMRT and 3D conformal radiation have demonstrated the superiority of protons in numerous pediatric malignancies and data on long-term clinical outcomes and toxicity is emerging. In this article, we review the existing clinical and dosimetric data regarding the use of proton beam radiation in malignant bone and soft tissue sarcomas.

    2017-01-01

    Full Text Available Epithelioid sarcoma (ES is a rare mesenchymal tumor of unknown histogenesis which displays multidirectional differentiation, predominantly epithelial. They have no normal cellular counterpart and differ from both synovial sarcoma and other carcinomas. It mainly affects young adults. It has two variants, classic type and proximal type. The more common classic type presents as a slowly growing painless nodule or plaque on the distal extremities. It is rare in children and older individuals. There is male predominance. The size varies from few millimeters to several centimeters. Central deeply seated lesions in pelvis and genital tract are termed as proximal ES. It has a multinodular growth pattern and usually occurs in older patients. These are comparatively more aggressive and metastasize early. On histopathological examination, these lesions need to be distinguished from other tumors showing epithelioid morphology. Primary ES of scalp is an exceedingly rare tumor. We present a case of nodular tumor on the scalp with cervical lymph node metastasis.

    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. Olaratumab for soft tissue sarcoma.

    Science.gov (United States)

    Teyssonneau, Diego; Italiano, Antoine

    2017-08-01

    Soft tissue sarcomas (STS) are rare malignant tumors. Unfortunately, the first-line doxorubicin-based treatment has not been improved since the 1970s. Platelet-derived growth factor (PDGF) receptor alpha (PDGFR-α) and its ligands are co-expressed in many types of cancer, including sarcomas. They are involved in stimulating growth and regulating stromal-derived fibroblasts and angiogenesis. PDGFR-α and its ligand may play an important role in tumorigenesis and be a potential target in the treatment of sarcomas. Olaratumab is a fully human IgG1-type anti-PDGFR-α monoclonal antibody with a high affinity and a low 50% inhibitory concentration (IC50). Areas covered: The authors review the role of olaratumab in the treatment of STS by focusing on the recent, randomized Phase II JDGD trial that challenged patients with unresectable or metastatic STS with doxorubicin in the presence or absence of olaratumab. This trial showed a great improvement in overall survival (OS), with an increase in survival from 14.7 months to 26.5 months for patients in the experimental arm and showed acceptable toxicity. Expert opinion: Results seem promising. However, it must be qualified, as the study includes several uncertainties. These uncertainties should be addressed by the ongoing Phase 3 JGDJ confirmatory trial, for which the final efficacy analysis is expected by 2019.

    2012-01-01

    Background Childhood cancer survivors have a six fold increased risk of developing subsequent neoplasms when compared to the general population. We sought to describe the occurrence of melanoma as a subsequent neoplasm among adult survivors of childhood cancer. Patients and Methods Among 14,358 5-year survivors of childhood cancer diagnosed between 1970–86, we calculated the cumulative incidence, standardized incidence ratio (SIR), and absolute excess risk (AER) of subsequent melanoma. Potential risk factors were assessed using a cause-specific hazards model. Results 57 melanomas (46 invasive, 2 ocular and 9 in situ) occurred in 51 survivors. The median time to the development of melanoma was 21.0 years (range 5.6–35.4 years) and the median age at melanoma was 32.3 years (range 10.9 – 49.0 years). Initial cancer diagnoses included soft tissue and bone sarcoma (n=15), leukemia (13), lymphoma (14), central nervous system malignancy (5), Wilms’ tumor (3), and neuroblastoma (1). The cumulative incidence of first subsequent melanoma at 35 years from initial cancer diagnosis was 0.55% (95% CI 0.37–0.73). The SIR of subsequent invasive malignant melanoma of the skin was 2.42 (95% CI 1.77 – 3.23), and the AER was 0.10 (95% CI 0.05 – 0.15) per 1,000 person years. No statistically significant associations were found between melanoma risk and family history of cancer, demographic, or treatment-related factors. Conclusion Survivors of childhood cancer have an approximate 2.5-fold increased risk of melanoma. Early screening and prevention strategies are warranted. PMID:22887858

    Full Text Available Pada asuransi multiple life, terdapat dua istilah berdasarkan status kematian dari kumpulan tertanggung yaitu joint life dan last survivor. Perbedaan status multiple life ini pada asuransi adalah waktu pemberian uang pertanggungannya. Suatu status dikatakan joint life jika pemberian uang pertanggungan dilakukan pada saat orang pertama meninggal dan status dikatakan life survivor jika pemberian uang pertanggungan dilakukan pada saat semuanya telah meninggal. Untuk mendapatkan uang pertanggungan, tertanggung haruslah membayarkan sejumlah premi. Jika ingin mengkonversikan premi tunggal menjadi premi berkala diperlukan anuitas. Untuk kasus asuransi last survivor kita akan menggunakan anuitas last survivor. Hasil akhir dari proses penelitian penulis akan menghasilkan rumusan matematika nilai sekarang anuitas awal dan anuitas akhir  untuk kasus dua orang dan tiga orang pada status last survivor.In multiple life insurance, there are two terms based on the status of the death of the insured is a collection of joint life and last survivor. The difference is in the status of multiple life insurance is the timing of cash coverage. A status is said to be a joint life insurance money if provision was made during the first die and life survivor status if the provision of insurance money made at the time are all dead. To get the sum insured, the insured must pay a premium. If you want to convert into a single premium be regular premium, annuity required. For the last survivor insurance cases we will use the last survivor annuity. The end result of the research process will generate mathematical formulas of present value due annuity and immediate annuity for the case of two and three people in the last survivor status.

    2016-01-01

    Aim:Limb salvage is the treatment of choice for lower extremity bone sarcomas in children. To date, peers have not described algorithms for soft tissue reconstruction of these defects. This paper is to report a large single center series of lower extremity salvage after sarcoma treatment, with algorithm. Methods:The authors performed a retrospective review of patients undergoing resection of lower extremity bone sarcomas at a single center over 12 years. Results:In total, 65 children (29 girls, 36 boys) with a mean age of 13 years (range 2.9-23.3 years) underwent resection of a lower leg sarcoma with limb-salvage. Tumors types included 50 osteosarcomas, and 15 Ewing sarcoma family of tumors. The types of reconstruction utilized included:34 primary closures, 22 gastrocnemius and soleus lfaps, 3 bipedicled lfaps, 2 sural artery lfaps, 1 pedicled anterolateral thigh lfap, 3 pedicled posterior thigh lfaps for subsequent above-knee amputations. No free lfap based reconstructions were performed. An algorithm for reconstruction of leg defects in the setting of limb-salvage surgery is presented. Successful limb salvage rate was 95.4%. Limb salvage failed in 3 patients and they required amputation. Finally, 56 patients were able to ambulate without assistance at last follow-up. Conclusion:The authors present an algorithm for the reconstruction soft tissue after resection of lower extremity bone sarcomas. The use of these techniques helps to decrease complications and maximize function in children with these tumors.

  9. Activation of PI3K/AKT and ERK MAPK signal pathways is required for the induction of lytic cycle replication of Kaposi's Sarcoma-associated herpesvirus by herpes simplex virus type 1

    Directory of Open Access Journals (Sweden)

    Lv Zhigang

    2011-10-01

    Full Text Available Abstract Background Kaposi's sarcoma-associated herpesvirus (KSHV is causally linked to several acquired immunodeficiency syndrome-related malignancies, including Kaposi's sarcoma (KS, primary effusion lymphoma (PEL and a subset of multicentric Castleman's disease. Regulation of viral lytic replication is critical to the initiation and progression of KS. Recently, we reported that herpes simplex virus type 1 (HSV-1 was an important cofactor that activated lytic cycle replication of KSHV. Here, we further investigated the possible signal pathways involved in HSV-1-induced reactivation of KSHV. Results By transfecting a series of dominant negative mutants and protein expressing constructs and using pharmacologic inhibitors, we found that either Janus kinase 1 (JAK1/signal transducer and activator of transcription 3 (STAT3 or JAK1/STAT6 signaling failed to regulate HSV-1-induced KSHV replication. However, HSV-1 infection of BCBL-1 cells activated phosphatidylinositol 3-kinase (PI3K/protein kinase B (PKB, also called AKT pathway and inactivated phosphatase and tensin homologue deleted on chromosome ten (PTEN and glycogen synthase kinase-3β (GSK-3β. PTEN/PI3K/AKT/GSK-3β pathway was found to be involved in HSV-1-induced KSHV reactivation. Additionally, extracellular signal-regulated protein kinase (ERK mitogen-activated protein kinase (MAPK pathway also partially contributed to HSV-1-induced KSHV replication. Conclusions HSV-1 infection stimulated PI3K/AKT and ERK MAPK signaling pathways that in turn contributed to KSHV reactivation, which provided further insights into the molecular mechanism controlling KSHV lytic replication, particularly in the context of HSV-1 and KSHV co-infection.

    Kaposi sarcoma is a vascular tumor manifesting as nodular lesions on skin, mucous membranes, or internal organs. This is a case of a 42-year-old human immunodeficiency virus- (HIV) positive bisexual male, not on highly active antiretroviral therapy (HAART) since diagnosis four years ago. He presented with a three-day history of abdominal pains, fever, vomiting, and a one-week history of melena stools. Endoscopy revealed Kaposi sarcoma in the stomach and duodenum. Postendoscopy, he developed acute abdomen. Exploratory laparotomy revealed extensive Kaposi sarcoma of the gastrointestinal tract with appendiceal involvement. The patient underwent appendectomy and had an uneventful recovery. A review of the literature discusses appendiceal Kaposi sarcoma with appendicitis, a rare but critical manifestation of gastrointestinal Kaposi sarcoma.

    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 sarcoma is an uncommon soft tissue malignancy usually arising in the extremities of young adults. Synovial sarcomas at unusual anatomic locations have been reported; however, to the best of our knowledge, there are no reports on primary synovial sarcoma in the rectovesical space. Here, we describe the radiologic findings of primary synovial sarcoma in the rectovesical space and review relevant literature.

    Full Text Available The prevalence of pain in patients with sarcoma is not well documented. We investigated this in outpatients at a tertiary cancer referral centre, assessing the adequacy of pain control and for risk factors leading to higher prevalence and severity of pain. 149 patients were surveyed. Patients with pain within the previous 7 days completed pain assessment tools (BPI, S-LANSS, PMI. 53% of patients had pain within the previous 7 days, and 25% had significant pain. Of those with pain, 63% was inadequately controlled and neuropathic pain was identified in 36%. Age, gender, tumour type, and the type of cancer treatment were not significant predictors of the prevalence or severity of the pain. Based on our results, patients with sarcoma should be actively screened for pain and have regular reviews of their analgesic requirements.

    Little is known about pain among long-term adult survivors of childhood cancers. The study investigated pain prevalence in this population compared with sibling controls and examined pain-related risk factors. Three self-reported pain outcomes including pain conditions, prescription analgesics used, and pain attributed to cancer and treatment were assessed among 10,397 cancer survivors and 3034 sibling controls from the Childhood Cancer Survivor Study. Pain conditions (pain/abnormal sensation, migraines, and other headaches) were reported by 12.3%, 15.5%, and 20.5% of survivors, respectively; 16.7% of survivors reported use of prescription analgesics, and 21% attributed pain to cancer and treatment. Risks of reporting pain conditions and using prescription analgesics were higher among survivors than siblings, adjusting for sociodemographic factors. Younger age at diagnosis and a history of non-Hodgkin lymphoma, Wilms tumor, or neuroblastoma (compared to leukemia) were associated with greater risk of reporting pain conditions. A history of bone cancer or soft tissue sarcoma (compared to leukemia) was associated with greater risks of using prescription analgesics and cancer-related pain attribution. Non-brain-directed scatter irradiation was associated with elevated risk for migraines and cancer-related pain attribution. Female gender and lower educational attainment were associated with increased reports of all 3 pain outcomes; minority status, unemployment, and being single were associated with greater risks for reporting pain conditions. These findings contribute to the understanding of pain and associated risk factors among adult survivors of childhood cancer and suggest areas of focus for pain intervention.

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

    2015-12-01

    Although dietary habits can affect colorectal cancer (CRC) survivors' health, it is unclear how familiar survivors are with dietary guidelines, what they believe about healthy eating and alcohol consumption, and what hinders healthy dietary habits after cancer. This study assessed CRC survivors' familiarity with dietary guidelines, their eating and drinking habits, and perceived facilitators and barriers to healthy eating after cancer, including social support and self-efficacy for maintaining a healthy diet and limiting alcohol. A total of 593 individuals (50% female; mean age, 74 years) diagnosed with CRC approximately 6 years prior to study entry in early 2010 were identified through California Cancer Registry records and participated in a cross-sectional mailed survey assessing health behavior after cancer (46% adjusted response rate). Analyses were conducted in 2014-2015. Survivors were most familiar with-and most likely to follow-recommendations to choose low-fat foods; 15% had never heard of recommendations to limit alcohol. Survivors were more aware of recommendations involving messages to limit/avoid versus approach/choose certain foods. The most common barrier to a healthy diet involved the effort required (26%). Survivors received more family/friend support and provider recommendations for healthy eating than limiting alcohol. Results provide an overview of awareness of and adherence to dietary recommendations among CRC survivors, highlighting the need for increasing awareness of recommendations that are especially relevant for survivors. Suggestions are made for modifying diet-related messages to facilitate comprehension and recall among CRC survivors, and increasing awareness among groups with the lowest awareness levels.

    PURPOSE Childhood cancer survivors (CCSs) are at increased risk for poor health-related quality of life (HRQOL) and chronic health conditions -- both of which can be exacerbated by unhealthy lifestyle behaviors. Developing a clearer understanding of the associations between HRQOL, lifestyle behaviors, and medical and demographic variables (e.g., age/developmental stage at time of diagnosis) is an important step toward developing more targeted behavioral interventions for this population. METHOD Cross-sectional questionnaires were completed by 170 CCSs who were diagnosed with leukemia, lymphoma, sarcoma, or a cancer of the central nervous system (CNS) and treated at a comprehensive cancer center between 1992 and 2007. Questionnaires addressed weight status, lifestyle behaviors, aspects of HRQOL, and intervention preferences. RESULTS Adolescent and young adult survivors (AYAs) and survivors of CNS tumors or lymphoma reported significantly (pexercise interventions. CONCLUSION Findings support the premise that females, AYAs, and survivors of cancers of the CNS or lymphoma are “at risk” subgroups within the CCS population for poor dietary practices, sedentary behaviors, and poor HRQOL. Future research should focus on developing diet and PA interventions to improve HRQOL that target these groups. IMPLICATIONS FOR SURVIVORS Greater consideration of the role of gender, developmental stage, and the HRQOL challenges facing CCSs may help researchers to develop targeted behavioral interventions for those who stand to benefit the most.

    2006-01-01

    Full Text Available Kaposi′s sarcoma is described as cutaneous and extracutaneous neoplasm predominantly affecting older individuals. Though earlier uncommon and endemic to certain African areas, its incidence is on a rise due to infections with human immunodeficiency virus and also due to transplant-associated immunosuppression. Further, certain benign conditions like Pseudo Kaposi′s sarcoma, certain infective conditions like bacillary angiomatosis of acquired immunodeficiency syndrome can mimic Kaposi′s sarcoma both clinically and histologically leading to a diagnostic dilemma. We report such a case here.

    Synovial sarcoma is the fourth most common type of sarcoma. It is usually found in the knee or ankle joints, and is exceptional in the head and neck. Most cases are diagnosed in men between 20 and 40 years of age. Diagnosis is often casual due to the infrequent nature of this tumour and its non-specific clinical and radiological characteristics. Confirmation is therefore based on immunohistochemistry and electron microscopy techniques. We report a case of biphasic sinovial sarcoma located in the infratemporal fossa treated at our hospital and we make a review of the literature. Copyright © 2009 Elsevier España, S.L.

    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)

  5. Pulmonary Artery Intimal Sarcoma: A Case Report

    2016-04-01

    Full Text Available Pulmonary artery intimal sarcomas are rare and lethal malignant tumors that typically affect larger vessels: the aorta, inferior vena cava, and pulmonary arteries. Since symptoms and imaging of pulmonary arterial intimal sarcomas mimic pulmonary thromboembolism, the differential diagnosis of a patient presenting with chest pain, dyspnea, and filling defect within the pulmonary arteries should include intimal sarcoma. Often right ventricular failure is observed due to pulmonary hypertension caused by the obstructive effect of the tumor and concomitant chronic thromboembolism. We report the case of a 72-year-old African-American male with arterial intimal sarcoma of the left and right pulmonary artery with extension through the right artery into the bronchus and right lung.

    2016-02-01

    Full Text Available INTRODUCTION Sarcomas are quite rare with only 15,000 new cases per year in the United States. Sarcomas therefore represent about one percent of the 1.5 million new cancer diagnoses in that country each year. Sarcoma can be defined as cancer whose cells originate from the cells of mesenchymal origin. The bones, cartilages, muscles are a few examples to be mentioned. This is in contrast to a malignant tumour originating from epithelial cells, which are termed carcinoma. AIMS AND OBJECTIVES 1. To clinically analyze the sarcomas. 2. To analyze the surgical outcome of this disease. The survival of the patient depends on the extent of metastasis and the primary identification. The study forms a base for further studies. So atleast it could be diagnosed earlier and treated to the full extent.

  10. Neurogenic sarcomas of the neck in neurofibromatosis.

    1981-01-01

    Based on two observations and a review of the literature, the pathological and clinical findings in sarcomas of the neck in patients with neurofibromatosis are described. Histologically these neurogenic tumours show a manifold picture; in addition to spindle-cell sarcomas pleomorphic structures are to be found, which can be similar to rhabdomyo-, lipo-, chondro-, angio-, or osteogenic sarcomas so that a histological diagnosis of a neurogenic sarcoma cannot always be made without clinical details. Up to the present surgical treatment is preferred; the value of cytostatic therapy and irradiation is controversial. The results of treating these tumours are unsatisfactory. Of 29 cases reported in the literature, only two could be found in which the patient survived without a recurrence for more than five years.

    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.

  12. Myeloid sarcoma of submandibular salivary gland

    2016-01-01

    Full Text Available Objective: To report a rare case of a myeloid sarcoma of submandibular salivary gland. Methods: A 65-year-old woman with a history of successfully treated myelodysplastic syndrome, presenting with periodic painful swelling of her right submandibular area. Results: Physical evaluation, ultrasound and CT scan revealed the presence of a 3-cm mass contiguous to the submandibular salivary gland. A core needle biopsy confirmed the diagnosis of myeloid sarcoma. Bone marrow biopsy was still showing complete remission and the submandibular gland was the only extramedullary site involved. The patient was submitted to chemotherapy. Conclusion: Myeloid sarcoma is a rare extramedullary neoplasm. It can virtually involve any anatomic site, but it usually involves lymph nodes, paranasal sinuses, skin, soft tissue and periostium. Myeloid sarcomas of salivary glands are very rare and ENTs should be aware of this disease in order to include it in the differential diagnosis of a solitary neck mass.

    Granulocytic sarcomas are rare extramedullary tumors of malignant myeloid precursor cells. Exceedingly rare in childhood, it commonly involves skin, lymph nodes, bone, and the spine. Ovarian involvement is rare. It can arise de novo, precede the development of acute nonlymphocytic leukemia, or be the sole manifestation of relapse. We describe a 26-year-old woman with granulocytic sarcoma of the ovary without any hematologic disorder.

    Full Text Available Acroangiodermatitis or Pseudo-Kaposi sarcoma is a rare angioproliferative entity, related to chronic venous insufficiency or certain other vascular anomalies. It is often associated with chronic venous insufficiency, arteriovenous malformation of the legs, chronic renal failure treated with dialysis, paralyzed legs and amputation stumps. We hereby describe a case of 45 year old female presenting with pitting pedal edema, multiple ulcers over bilateral lower limbs with irregular margins with erythema and hyperpigmentation of the surrounding skin. Color Doppler study of bilateral lower limbs was normal. Histopathological examination from one of the lesions showed hyperplastic epidermis, proliferation of capillaries in dermis, hemosiderin deposits and lymphocytic infiltrate. These features thus confirmed the diagnosis of Acroangiodermatitis.

Primary pulmonary SS is an extremely rare tumor. We report a case of primary SS of lung who presented with severe chest pain and a large right lung mass with right-sided pleural effusion in computed tomography (CT scan of thorax. The diagnosis was made on the basis of CT-guided core biopsy and immunohistochemistry. On immunohistochemistry, tumor cell expressed epithelial membrane antigen, bcl 2, Vimentin and smooth muscle actin and were immunonegative for S100 and cytokeratin. So, the final diagnosis was primary SS.

    Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, occurs commonly in the soft tissues in adult, but is rare in the maxillofacial region. It consists of undifferentiated mesenchymal tumor cells resembling histiocytes and fibroblasts. The purpose of this article is to report a case of UPS in the mandible. A 44-year-old patient presented with a painful growing mass in the mandible of two months' duration. Computed tomography and positron emission tomography-computed tomography revealed an ill-defined heterogenous, hypermetabolic mass about 4 cm in size in the left mandible invading adjacent soft tissues. A left mandiblulectomy and reconstruction with a fibular free flap were performed. Immunohistochemical study gave a diagnosis of UPS. The patient was referred for adjuvant chemotherapy after surgical removal of the tumor.

    Although progress has been made in the treatment of childhood brain tumors,work remains to understand the complexities of disease, treatment, and contextual factors that underlie individual differences in outcome. A combination of both an idiographic approach (incorporating observations made by adult survivors of childhood brain tumors) and a nomothetic approach (reviewing the literature for brain tumor survivors as well as childhood cancer survivors) is presented. Six areas of concern are reviewed from both an idiographic and nomothetic perspective, including social/emotional adjustment, insurance, neurocognitive late effects, sexuality and relationships, employment, and where survivors accessed information about their disease and treatment and possible late effects. Guidelines to assist health care professionals working with childhood brain tumor survivors are offered with the goal of improving psychosocial and neurocognitive outcomes in this population.

    Two studies examined the social and emotional implications of different linguistic classifications of individuals with cancer. Undergraduates were randomly assigned to rate their reactions to either cancer patients or cancer survivors. Across studies, participants held more favorable perceptions of the character of cancer survivors relative to cancer patients and displayed more positive attitudes toward the former group. In addition, participants in Study 1 reported greater willingness to interact with cancer survivors compared with cancer patients. Positive perceptions of prognosis did not appear to account for favorable attitudes toward cancer survivors; most participants in Study 2 did not assume that cancer survivors were beyond the treatment phase of their illness or cured of their disease. Findings point to a potentially powerful effect of word choice on reactions to individuals with cancer. PMID:24371366

  4. Potential Therapeutic Targets in Uterine Sarcomas

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Uterine sarcomas are rare tumors accounting for 3,4% of all uterine cancers. Even after radical hysterectomy, most patients relapse or present with distant metastases. The very limited clinical benefit of adjuvant cytotoxic treatments is reflected by high mortality rates, emphasizing the need for new treatment strategies. This review summarizes rising potential targets in four distinct subtypes of uterine sarcomas: leiomyosarcoma, low-grade and high-grade endometrial stromal sarcoma, and undifferentiated uterine sarcoma. Based on clinical reports, promising approaches for uterine leiomyosarcoma patients include inhibition of VEGF and mTOR signaling, preferably in combination with other targeted or cytotoxic compounds. Currently, the only targeted therapy approved in leiomyosarcoma patients is pazopanib, a multitargeted inhibitor blocking VEGFR, PDGFR, FGFR, and c-KIT. Additionally, preclinical evidence suggests effect of the inhibition of histone deacetylases, tyrosine kinase receptors, and the mitotic checkpoint protein aurora kinase A. In low-grade endometrial stromal sarcomas, antihormonal therapies including aromatase inhibitors and progestins have proven activity. Other potential targets are PDGFR, VEGFR, and histone deacetylases. In high-grade ESS that carry the YWHAE/FAM22A/B fusion gene, the generated 14-3-3 oncoprotein is a putative target, next to c-KIT and the Wnt pathway. The observation of heterogeneity within uterine sarcoma subtypes warrants a personalized treatment approach.

This paper highlights some key ethical issues and summarizes recent evidence relating to participation in, and conduct of, trauma-focused studies with special reference to vulnerable populations (eg, women and children, refugees, survivors of human rights violations, and survivors of trauma in the developing world). A concise ethical framework, rather than rigid guidelines (that may not be applicable to all trauma studies), may be a more useful point of reference for investigators and ethics committees or institutional review boards. Despite the increased empiric data available to inform ethical dilemmas regarding trauma research, more cost-burden analysis research in varying trauma populations and careful investigation of factors that contribute to risk and benefit is required.

    Primary lung sarcomas are rare but aggressive tumors accounting for less than 0.5% of all lung tumors. The diagnosis of primary lung sarcoma should only be considered after exclusion of other sites. A 32-year-old female presented with recurrent hemorrhagic pleural effusions, shortness of breath and persistent cough. Pleural effusion was drained twice, and each time its analysis was normal. Patient developed atelectasis of left lung with hemothorax for which she underwent video-assisted thoracoscopic surgery. A large mass was found compressing the entire lower lobe of left lung with extension into mediastinum, the biopsy of which showed myxoid sarcoma. The tumor was inoperable and options of chemotherapy or radiotherapy were discussed with the patient. Primary lung sarcoma can rarely present with recurrent hemorrhagic pleural effusion. A high degree of suspicion is required for early diagnosis as large hemothorax on computed tomography or chest X-ray may obscure lung mass and make its diagnosis difficult.

  9. Synovial sarcoma with relevant immunocytochemistry and special emphasis on the monophasic fibrous variant

    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 is an uncommon lethal tumour of the long bones and pelvic girdle mainly affecting children and young adults. An origin in the cranial bones is extremely rare. We report a unique case of primary involvement of the greater wing of sphenoid bone in a 16-year-old patient. Aggressive management using microsurgical resection, radiotherapy and chemotherapy was curative. Localized, primary Ewing's sarcoma of the cranial bones should be considered as a distinct clinicopathological entity with an extremely low rate of dural penetration and metastases, and with a relatively better prognosis as compared with those of long bones and pelvic girdle. In neurosurgical practice, primary Ewing's sarcoma of the cranial bones requires early aggressive management to achieve adequate long-term prognosis and cure.

    Full Text Available Although multimodal therapies including surgery, chemotherapy, and radiotherapy have improved clinical outcomes of patients with bone and soft tissue sarcomas, the prognosis of patients has plateaued over these 20 years. Immunotherapies have shown the effectiveness for several types of advanced tumors. Immunotherapies, such as cytokine therapies, vaccinations, and adoptive cell transfers, have also been investigated for bone and soft tissue sarcomas. Cytokine therapies with interleukin-2 or interferons have limited efficacy because of their cytotoxicities. Liposomal muramyl tripeptide phosphatidylethanolamine (L-MTP-PE, an activator of the innate immune system, has been approved as adjuvant therapeutics in combination with conventional chemotherapy in Europe, which has improved the 5-year overall survival of patients. Vaccinations and transfer of T cells transduced to express chimeric antigen receptors have shown some efficacy for sarcomas. Ipilimumab and nivolumab are monoclonal antibodies designed to inhibit immune checkpoint mechanisms. These antibodies have recently been shown to be effective for patients with melanoma and also investigated for patients with sarcomas. In this review, we provide an overview of various trials of immunotherapies for bone and soft tissue sarcomas, and discuss their potential as adjuvant therapies in combination with conventional therapies.

    Classical Kaposi sarcoma (KS) usually appears on lower extremities accompanied or preceded by local lymphedema. However, the development in areas of chronic lymphedema of the arms following mastectomy, mimicking a Stewart-Treves syndrome, has rarely been described. We report an 81-year-old woman who developed multiple, erythematous to purple tumors, located on areas of post mastectomy lymphedema. Histopathological examination evidenced several dermal nodules formed by spindle-shaped cells that delimitated slit-like vascular spaces with some red cell extravasation. Immunohistochemically, the human herpesvirus type 8 (HHV-8) latent nuclear antigen-1 was detected in the nuclei of most tumoral cells confirming the diagnosis of KS. Lymphedema could promote the development of certain tumors by altering immunocompetence. Although angiosarcoma (AS) is the most frequent neoplasia arising in the setting of chronic lymphedema, other tumors such as benign lymphangiomatous papules (BLAP) or KS can also develop in lymphedematous limbs. It is important to establish the difference between AS and KS because their prognosis and treatment are very different. Identification by immunohistochemistry of HHV-8 is useful for the distinction between KS and AS or BLAP.

    Background: Although the number of cancer survivors has increased substantially over the past several decades, the composition of survivors treated with radiotherapy is not well defined. Radiotherapy carries unique long-term toxicity risks for cancer survivors. This study describes the current estimates and future projections of the epidemiology of 5-year cancer survivors who receive radiation therapy.Methods: We used cancer incidence and survival data from the Surveillance, Epidemiology, and End-Results (SEER) database linked to U.S. Census data to estimate the number of 5-year cancer survivors treated with radiation between 2000 and 2030. Future projections assumed continuing incidence and survival trends based on historical rates.Results: In 2016, there were an estimated 3.05 million cancer survivors treated with radiation, accounting for 29% of all cancer survivors. The number of radiation-treated cancer survivors is projected to reach 3.38 million by 2020 and 4.17 million by 2030. In 2016, breast (40%) and prostate cancer (23%) composed the majority of radiation-treated survivors, followed by head and neck cancer (5.8%), lymphoma (5.6%), uterine (3.9%), and rectal cancer (3.8%). The percentage of 70 years or older radiation-treated survivors steadily increased between 2000 and 2030.Conclusions: The next several years are projected to see a large increase in the number of cancer survivors treated with radiation.Impact: This group of cancer survivors has unique needs given the long-term risks of radiation, and increased research and awareness are required to optimize health of this growing population.

    Full Text Available Os sarcomas com apresentação cutânea primária são tumores raros e de grande heterogeneidade histológica. Com a evolução da oncologia cutânea e da cirurgia dermatológica, os dermatologistas têm sido cada vez mais requisitados para o diagnóstico e orientação terapêutica de tumores menos freqüentes. Este artigo de revisão analisa os sarcomas cutâneos primários observando suas características clínicas, etiopatogênicas e histológicas, bem como aspectos do tratamento e evolução. Enfatiza os sarcomas de maior relevância para o dermatologista, como angiossarcoma, dermatofibrossarcoma protuberans, fibroxantoma atípico, leiomiossarcoma, lipossarcoma, tumor maligno de bainha de nervo periférico e sarcoma epitelióide. O sarcoma de Kaposi não é abordado devido a suas características individuais específicas.Soft tissue tumors represent a heterogeneous group of mesenchymal and neural lesions. The cutaneous presentation of these tumours is rare. With the evolution of dermatologic surgery and cutaneous oncology, dermatologists have emerged as specialists for skin cancer management. This article reviews primary cutaneous sarcomas with particular emphasis on the epidemiologic, clinical, and histological features of diagnosis, as well as treatment modalities and prognosis. The most frequent cutaneous sarcomas were reviewed, including angiosarcoma, dermatofibrosarcoma protuberans, atypical fibroxanthoma, leiomyosarcoma, liposarcoma, malignant nerve sheath tumor, and epithelioid sarcoma. Kaposi's sarcoma, due to specific characteristics, was omitted from this review.

    We conducted a literature review to determine the clinical characteristics of genital sarcoma during pregnancy. The systematic literature search was conducted using the search engines PubMed and MEDLINE with keywords "sarcoma" and "pregnancy" and was limited to female genital organs such as ovary, uterus, cervix, vagina, vulva, and retroperitoneal sarcoma. Kaposi's sarcoma, metastatic sarcoma, history of sarcoma, bone sarcoma located in pelvis, and fetal sarcoma were excluded in this study. There were 40 cases of genital sarcoma during pregnancy between 1955 and 2007. The majority of the cases were uterine sarcoma (37.5%), followed by retroperitoneal sarcoma (27.5%), vulvar sarcoma (22.5%), and vaginal sarcoma (12.5%). Mean age of the patient was 27.8 +/- 7.0. The distribution in the onset of symptoms had two peaks: first trimester (27.5%) and third trimester (50.0%). Growing mass (42.5%), abdominal pain (30.0%), and vaginal bleeding (22.5%) were the three most common symptoms. Incidental diagnosis was made in 22.5% and included during cesarean section (12.5%) and routine pelvic exam (7.5%). The cases initially not suspicious for malignancy were 42.5%. Thirty-three (82.5%) cases had live-born infants with term delivery in 55.2%. Mean birth weight was 2843 +/- 791 g, and male infants were more common (66.7%). Intrauterine growth retardation was seen in 12.5% of cases. Preterm labor was a common complication. Median survival period was 2.5 years (95% confidence, 1.9 to 3.1). The 2-, 3-, and 5-year cumulative survival rates were 60%, 38%, and 17%, respectively. Genital sarcomas in pregnancy are rare. There is a delay in diagnosis due to low index of suspicion. A majority had live births, and the 5-year survival is similar to that of advanced-stage sarcoma in nonpregnant women.

    We report a case of granulocytic sarcoma exclusively manifesting as diffuse intramuscular infiltration of the proximal upper and lower limb girdle and the torso muscles in a patient with previous history of acute myelogenous leukemia 5a. Whole-body CT showed widespread distribution of ill-defined intramuscular, homogeneously enhancing lesions. On whole-body MRI, lesions were homogeneously hyperintense on fat saturated T2-weighted images, isointense on T1-weighted images and strongly enhancing after intravenous gadolinium contrast administration. Histopathology revealed muscular infiltration of blast cells with identical immunochemistry to the initial manifestation of leukemia, diagnostic for an extramedullary relapse manifesting as granulocytic sarcoma. CT and MRI characteristics of this previously undocumented manifestation of granulocytic sarcoma should assist in the identification of such cases. (orig.)

    Full Text Available Primary breast sarcoma is the least frequent non-epithelial malignant tumour, representing less than 1 % of all breast cancers. It has a dismal prognosis with the presence of early metastases, mainly in the lungs and bones. Survival is very poor at 5 years. A case of a 79 year-old female patient with a large ulcerated sarcoma in the left breast is presented. The patient was examined in an interdisciplinary consultation, and the presence of a stromal sarcoma of the breast without apparent visceral or bone metastases was confirmed by an aspiration biopsy with thick needle, excisional biopsy by paraffin and by immunohistochemical studies. The publication of this report has clinical interest for health professionals due to the rarity of the disease.

    To study the biodistribution of MSCs, we labeled adult murine C57BL/6 MSCs with firefly luciferase and DsRed2 fluorescent protein using nonviral Sleeping Beauty transposons and coinfused labeled MSCs with bone marrow into irradiated allogeneic recipients. Using in vivo whole-body imaging, luciferase signals were shown to be increased between weeks 3 and 12. Unexpectedly, some mice with the highest luciferase signals died and all surviving mice developed foci of sarcoma in their lungs. Two mice also developed sarcomas in their extremities. Common cytogenetic abnormalities were identified in tumor cells isolated from different animals. Original MSC cultures not labeled with transposons, as well as independently isolated cultured MSCs, were found to be cytogenetically abnormal. Moreover, primary MSCs derived from the bone marrow of both BALB/c and C57BL/6 mice showed cytogenetic aberrations after several passages in vitro, showing that transformation was not a strain-specific nor rare event. Clonal evolution was observed in vivo, suggesting that the critical transformation event(s) occurred before infusion. Mapping of the transposition insertion sites did not identify an obvious transposon-related genetic abnormality, and p53 was not overexpressed. Infusion of MSC-derived sarcoma cells resulted in malignant lesions in secondary recipients. This new sarcoma cell line, S1, is unique in having a cytogenetic profile similar to human sarcoma and contains bioluminescent and fluorescent genes, making it useful for investigations of cellular biodistribution and tumor response to therapy in vivo. More importantly, our study indicates that sarcoma can evolve from MSC cultures.

    The role of FDG PET/CT in management of soft tissue and bone sarcomas has been described in many studies up-to-date. However, contribution of PET/CT to diagnosis and treatment in some types of sarcomas that are seen with low incidence has not been identified properly yet. Clear cell sarcoma, synovial sarcoma of chest and myxoid lyposarcoma are rare types of sarcomas. We aimed to describe the FDG uptake patterns of these rare tumors and find out the role of FDG PET/CT in management of disease. Copyright © 2012 Elsevier España, S.L. and SEMNIM.

    The association between Kaposi's sarcoma and infection with human herpesvirus 8 is now well recognized. Immunologic impairment is associated with 2 forms of Kaposi's sarcoma, epidemic [associated with human immunodeficiency virus (HIV) infection] and iatrogenic (associated with immunosuppressive treatment); both forms have become more common during the last decade. We describe an HIV negative 54-year-old man who developed Kaposi's sarcoma 2 months after the beginning of immuno-suppressive therapy for Wegener's granulomatosis (WG). With tapering of medication, complete remission of Kaposi's sarcoma was achieved in one year. To our knowledge, this is the second reported case of iatrogenic Kaposi's sarcoma in a patient with WG.

  9. Potential molecular targets for Ewing′s sarcoma therapy

    Directory of Open Access Journals (Sweden)

    Babu Jully

    2012-01-01

    Full Text Available Ewing′s sarcoma (ES is a highly malignant tumor of children and young adults. Modern therapy for Ewing′s sarcoma combines high-dose chemotherapy for systemic control of disease, with advanced surgical and/or radiation therapeutic approaches for local control. Despite optimal management, the cure rate for localized disease is only approximately 70%, whereas the cure rate for metastatic disease at presentation is less than 30%. Patients who experience long-term disease-free survival are at risk for significant side-effects of therapy, including infertility, limb dysfunction and an increased risk for second malignancies. The identification of new targets for innovative therapeutic approaches is, therefore, strongly needed for its treatment. Many new pharmaceutical agents have been tested in early phases of clinical trials in ES patients who have recurrent disease. While some agents led to partial response or stable disease, the percentages of drugs eliciting responses or causing an overall effect have been minimal. Furthermore, of the new pharmaceuticals being introduced to clinical practice, the most effective agents also have dose-limiting toxicities. Novel approaches are needed to minimize non-specific toxicity, both for patients with recurrence and at diagnosis. This report presents an overview of the potential molecular targets in ES and highlights the possibility that they may serve as therapeutic targets for the disease. Although additional investigations are required before most of these approaches can be assessed in the clinic, they provide a great deal of hope for patients with Ewing′s sarcoma.

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

    Kaposi's Sarcoma associated Herpesvirus (KSHV) is the most recently discovered human tumor virus and is associated with the pathogenesis of Kaposi's sarcoma, primary effusion lymphoma, and Multicentric Casttleman's disease. KSHV contains numerous open reading frames with striking homology to cellular genes. These viral gene products play a variety of roles in KSHV-associated pathogenesis by disrupting cellular signal transduction pathways, which include interferon-mediated anti-viral responses, cytokine-regulated cell growth, apoptosis, and cell cycle control. In this review, we will attempt to cover our understanding of how viral proteins deregulate cellular signaling pathways, which ultimately contribute to the conversion of normal cells to cancerous cells.

    Cooper, T M

    2012-02-03

    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.

    Objectives: Chloroma (granulocytic sarcoma) is a rare, extramedullary tumor of immature myeloid cells related to acute nonlymphocytic leukemia or myelodysplastic syndrome. Radiation therapy (RT) is often used in the treatment of chloromas; however, modern studies of RT are lacking. We reviewed our experience to analyze treatment response, disease control, and toxicity associated with RT to develop treatment algorithm recommendations for patients with chloroma. Patients and Methods: Thirty-eight patients who underwent treatment for chloromas at our institution between February 1990 and June 2010 were identified and their medical records were reviewed and analyzed. Results: The majority of patients that presented with chloroma at the time of initial leukemia diagnosis (78%) have not received RT because it regressed after initial chemotherapy. Yet most patients that relapsed or remained with chloroma after chemotherapy are in the RT cohort (90%). Thirty-three courses of RT were administered to 22 patients. Radiation subsite breakdown was: 39% head and neck, 24% extremity, 9% spine, 9% brain, 6% genitourinary, 6% breast, 3% pelvis, and 3% genitourinary. Median dose was 20 (6-36) Gy. Kaplan-Meier estimates of progression-free survival and overall survival in the RT cohort were 39% and 43%, respectively, at 5 years. At a median follow-up of 11 months since RT, only 1 patient developed progressive disease at the irradiated site and 4 patients developed chloromas at other sites. RT was well tolerated without significant acute or late effects and provided symptom relief in 95% of cases. Conclusions: The majority of patients with chloromas were referred for RT when there was extramedullary progression, marrow relapse, or rapid symptom relief required. RT resulted in excellent local disease control and palliation of symptoms without significant toxicity. We recommend irradiating chloromas to at least 20 Gy, and propose 24 Gy in 12 fractions as an appropriate regimen.

    To identify employer-related barriers and facilitators for work participation of cancer survivors from the perspective of both employers and cancer survivors, and to synthesise these perceived barriers and facilitators to understand their perceived consequences. A systematic review of qualitative studies focusing on employers' and cancer survivors' perspectives on the work participation of cancer survivors was performed. Four databases (MEDLINE, EMBASE, PsycINFO, and Business Source Premier) were systematically searched, and the quality of studies included was assessed using the CASP checklist. Perceived barriers and facilitators were extracted and synthesised to conduct a content analysis. Five studies representing the employers' perspectives and 47 studies representing the cancer survivors' perspectives were included. Employers perceived barriers and facilitators related to support, communication, RTW policies, knowledge about cancer, balancing interests and roles, and attitude. Survivors perceived barriers and facilitators related to support, communication, work environment, discrimination, and perception of work ability. The synthesis found that the employers' willingness to support can be understood by perceptions they have of the survivor, goals of the employer, and national or organisational policies. Employers require knowledge about cancer and RTW policies to be able to support survivors. This review identified a plurality of and a large variety in perceived employer-related barriers and facilitators for work participation of cancer survivors, which can be understood to be related to both employers' willingness and ability to support. There is a need for interventions targeting employers, with the aim of enhancing the sustainable work participation of cancer survivors. Copyright © 2017 John Wiley & Sons, Ltd.

    Two cases of osteogenic sarcoma with skeletal muscle metastases are described. A 40-year-old woman presented with progressive swelling of both calves and a soft tissue back lump. She had been diagnosed with mandibular chondroblastic osteogenic sarcoma 6 years earlier. Radiographs showed calcified masses. MRI scans and bone scintigraphy revealed multiple soft tissue masses in both calves. Bone scintigraphy also showed uptake in the back lump, right thigh and left lung base. Biopsy confirmed metastatic chondroblastic osteogenic sarcoma, which initially responded well to chemotherapy. However, the metastatic disease subsequently progressed rapidly and she died 21 months after presentation. The second case concerns a 20-year-old man who presented with a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector spinae and gluteal muscles. The patient`s disease progressed rapidly and he died 30 months after presentation. (orig.) With 6 figs., 29 refs.

    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.

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

    Between 1978 and 1989, 32 patients with unfavorable soft tissue sarcoma underwent light ion (helium, neon) irradiation with curative intent at Lawrence Berkeley Laboratory. The tumors were located in the trunk in 22 patients and head and neck in 10. Macroscopic tumor was present in 22 at the time of irradiation. Two patients had tumors apparently induced by previous therapeutic irradiation. Follow-up times for surviving patients ranged from 4 to 121 months (median 27 months). The overall 3-year actuarial local control rate was 62%; the corresponding survival rate was 50%. The 3-year actuarial control rate for patients irradiated with macroscopic tumors was 48%, while none of the patients with microscopic disease developed local recurrence (100%). The corresponding 3-year actuarial survival rates were 40% (macroscopic) and 78% (microscopic). Patients with retroperitoneal sarcoma did notably well; the local control rate and survival rate were 64% and 62%, respectively. Complications were acceptable; there were no radiation related deaths, while two patients (6%) required operations to correct significant radiation-related injuries. These results appear promising compared to those achieved by low -LET irradiation, and suggest that this technique merits further investigation.

  12. GLUT1 Expression in Synovial Sarcomas

    Full Text Available Objective: In this study, the role of GLUT1 expression in synovial sarcomas and its association with disease pathogenesis were examined.Materials and Methods: Twenty two cases of synovial sarcoma were included in this study. The clinicopathological features of the cases, such as age, sex, localization of tumor, information of primary or metastatic tumor, histopathological type were recorded. The tissue microarray paraffin block containing tumor tissues was built by using tissue microarrayer. GLUT1 expression was analyzed on tissue sections by immunohistochemistry.Results: A total of 22 cases (mean age 36 years; range 14-54 years were analyzed. All cases except one were primary tumors. The tumors showed monophasic histological type in 13 cases and biphasic type in 9 cases. GLUT1 expression was found in 3 cases with biphasic type (14%. The cytoplasmic and incomplete membranous GLUT1 expression was seen in the tumor cells showing epithelial-glandular differentiation, whereas spindled cells were negative.Conclusion: Although GLUT1 expression is a diagnostic marker for juvenile capillary hemangioma and perineural tumors, both of which included in the group of mesenchymal tumors, it can be seen in a subset of synovial sarcomas. In our series, the observation of GLUT1 expression especially in the epithelial component of biphasic synovial sarcomas suggests that; i GLUT1 may be relatively used by tumoral cells composing epithelial component of the tumor, and ii the spindle cell component of the tumor would have been positive for other glucose transporters. The finding of uncommon GLUT1 expression in synovial sarcomas is indirectly consistent with the reported results of decreased standardized uptake value by Positron emission tomography with 2-[18F]fluoro-2-deoxy-D-glucose method in the literature.

  13. The Challenges of Detecting Circulating Tumor Cells in Sarcoma

    Sarcomas are a heterogeneous group of malignant neoplasms of mesenchymal origin, many of which have a propensity to develop distant metastases. Cancer cells that have escaped from the primary tumor are able to invade into surrounding tissues, to intravasate into the bloodstream to become circulating tumor cells (CTCs), and are responsible for the generation of distant metastases. Due to the rarity of these tumors and the absence of specific markers expressed by sarcoma tumor cells, the characterization of sarcoma CTCs has to date been relatively limited. Current techniques for isolating sarcoma CTCs are based on size criteria, the identification of circulating cells that express either common mesenchymal markers, sarcoma-specific markers, such as CD99, CD81, or PAX3, and chromosomal translocations found in certain sarcoma subtypes, such as EWS-FLI1 in Ewing’s sarcoma, detection of osteoblast-related genes, or measurement of the activity of specific metabolic enzymes. Further studies are needed to improve the isolation and characterization of sarcoma CTCs, to demonstrate their clinical significance as predictive and/or prognostic biomarkers, and to utilize CTCs as a tool for investigating the metastatic process in sarcoma and to identify novel therapeutic targets. The present review provides a short overview of the most recent literature on CTCs in sarcoma. PMID:27656422

    1999-08-01

    Sensorineural hearing loss (SNHL) is a significant neurologic morbidity in survivors of neonatal congenital diaphragmatic hernia (CDH), with a reported incidence of up to 60%. In a historical cohort study of 37 neonates with CDH, we investigated the use of pancuronium bromide (PB) and common ototoxic drugs during the neonatal period and their relationship to SNHL in childhood survivors. Survivors with SNHL (n = 23) had significantly higher cumulative dose of PB administered during the neonatal illness than survivors without SNHL (n = 14). The cumulative dose and duration of PB use significantly correlated (r = 0.66-0.81) and independently predicted (adjusted r (2) = 0.42-0.64) the greatest intensity (in decibels) and the widest band (lowest frequency in hertz) loss of SNHL. No differences were identified between survivors with and without SNHL regarding demographic and neonatal characteristics (including oxygenation and ventilation variables and the cumulative dose and duration of therapy with aminoglycosides, vancomycin, and furosemide), although survivors with SNHL had received a modestly higher cumulative dose of ethacrynic acid than survivors without SNHL. Although we show that prolonged administration of PB during the neonatal period is associated with SNHL in childhood survivors of CDH, further multicenter studies are required to investigate the possible etiologies of SNHL in this high-risk population.

    2004-04-01

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

    The Bone Marrow Transplant Survivor Study is a retrospective cohort study in which participants who received hematopoietic cell transplantation (HCT) between 1974 and 1998 and survived for 2 years completed a 255-item questionnaire on late effects occurring after HCT. There were 281 survivors with acute myeloid leukemia (AML) and 120 with acute lymphoblastic leukemia (ALL). Siblings of participants (n=319) were recruited for comparison. Median age at interview was 36.5 years for survivors and 44 years for siblings. Median follow-up after HCT was 8.4 years. Conditioning included total body irradiation in 86% of AML and 100% of ALL subjects. The frequencies of late effects did not differ between ALL and AML survivors. Compared with siblings, survivors had a higher frequency of diabetes, hypothyroidism, osteoporosis, exercise-induced shortness of breath, neurosensory impairments and problems with balance, tremor or weakness. In multivariable analysis, the risk of these outcomes did not differ by diagnosis. Survivors after allogeneic HCT had higher odds of diabetes (odds ratio (OR)=3.9, P=0.04), osteoporosis (OR=3.1, P=0.05), abnormal sense of touch (OR=2.6, P=0.02) and reported their overall health as fair or poor (OR=2.2, P=0.03). Ongoing surveillance for these late effects and appropriate interventions are required to improve the health status of ALL and AML survivors after HCT.

    Full Text Available There has been a dramatic increase in the number of childhood cancer survivors living to an old age due to improved cancer treatments. However, these survivors are at risk of numerous late effects as a result of their cancer therapy. Engaging in protective health behaviors and limiting health damaging behaviors are vitally important for these survivors given their increased risks. We reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings. We examine the prevalence of a variety of health behaviors among childhood cancer survivors, identify significant risk factors, and describe health behavior interventions for survivors.

    5cm, while they ranged from 1,5 to 15cm. Surgery was made in 17 patients, with eleven amputation. Tumors margins were free in fifteen patients, positive in three and in seven were not studied. Six received any type of quimiotherapy and 14 received treatment with radiotherapy with mean dose of 46,5 Gy. Local recurrence occurred in thirteen cases (52%. Nodal spread was diagnosed in nine (36%. Pulmonary metastases were diagnosed in seven patients (28%. Six patients underwent cancer treatment in its entirety at the National Institute of Cancer. At present twelve patients are alive without disease, two have disease and eleven patients have died. CONCLUSION: Epithelioid sarcoma is a rare subset of soft tissue sarcoma with high rate of local recurrence, regional node and distant metastases. Occurs predominantly in young patients, mainly on the superior member extremities. Surgical treatment of epithelioid sarcoma consists of early wide local resection to negative microscopic margins. These patients require carefully follow-up to evaluate local recurrence, nodal metastases, and pulmonary metastases.

    Ewing sarcoma is a malignant bone cancer that primarily occurs in children and adolescents. Eighty-five percent of Ewing sarcoma is characterized by the presence of the aberrant chimeric EWS/FLI1 fusion gene. Previously, we demonstrated that an interaction between EWS/FLI1 and wild-type EWS led to the inhibition of EWS activity and mitotic dysfunction. Although defective mitosis is considered to be a critical step in cancer initiation, it is unknown how interference with EWS contributes to Ewing sarcoma formation. Here, we demonstrate that EWS/FLI1- and EWS-knockdown cells display a high incidence of defects in the midzone, a midline structure located between segregating chromatids during anaphase. Defects in the midzone can lead to the failure of cytokinesis and can result in the induction of aneuploidy. The similarity among the phenotypes of EWS/FLI1- and EWS siRNA-transfected HeLa cells points to the inhibition of EWS as the key mechanism for the induction of midzone defects. Supporting this observation, the ectopic expression of EWS rescues the high incidence of midzone defects observed in Ewing sarcoma A673 cells. We discovered that EWS interacts with Aurora B kinase, and that EWS is also required for recruiting Aurora B to the midzone. A domain analysis revealed that the R565 in the RGG3 domain of EWS is essential for both Aurora B interaction and the recruitment of Aurora B to the midzone. Here, we propose that the impairment of EWS-dependent midzone formation via the recruitment of Aurora B is a potential mechanism of Ewing sarcoma development.

    To report functional (physical and cognitive) late effects, experiences, and information needs of adult survivors of childhood cancer. Descriptive, mixed methods survey. Two pediatric oncology programs in the Midwest. Convenience sample of 272 young adult survivors. Voluntary survey completion by young adult survivors regarding late effects, experiences, and educational needs to develop appropriate comprehensive care programs for care provision before, during, and after transition to adult care. Survey domains were identified from existing survivorship literature and focused on all aspects of survivorship; however, this article focuses on results specific to the functional domain. Functional late effects, experiences, information needs, age, gender, and treatment intensity of young adult survivors of childhood cancer. Response rate was 48%. Functional late effects, perceptions, and information needs all correlated with intensity of treatment (those survivors most heavily treated experienced the most symptoms). Survivors wanted more information about late effects and how to deal with them. Women wanted more information about fertility-related topics, and participants who received more intense treatment generally wanted more information. Brain tumor survivors perceived greater cognitive difficulties, cognitive late effects, fatigue, and financial difficulties. Survivors experience myriad physical late effects and require ongoing access to information as needs change over time. Identifying new and innovative ways to reach survivors and better meet needs is important for care, research, and program development. The findings of the research underscore the importance of continuous learning opportunities for adult survivors of childhood cancer. The findings also highlight the need for healthcare teams to better understand the current and long-term needs of this population. In addition to traditional communication approaches, technologies such as social media and

    Kaposi's sarcoma is a vascular tumour characterized by a proliferation of spindle cells and endothelial cells to form closely arranged slit-like vascular spaces. Currently, the definitive diagnosis of Kaposi's sarcoma relies on histology. The dermoscopic features of Kaposi's sarcoma are not clearly defined in the scientific literature. We seek to evaluate the dermoscopic features of Kaposi's sarcoma and compare them with other vascular tumours. One hundred forty-one lesions from seven patients with histologically proven Kaposi's sarcoma were evaluated using polarized light dermoscopy for the presence of various dermoscopic features. Twenty patients with other vascular tumours were also examined. Dermoscopic examination revealed bluish-reddish coloration (84% of lesions), multicoloured areas showing various colours of the rainbow spectrum (36%), scaly surface (29%), and small brown globules (15%). The 'rainbow pattern' was found in six out of seven patients with Kaposi's sarcoma and was not observed in other vascular tumours. In addition, there was an absence of dermoscopic features specific for other vascular and non-vascular skin tumours, such as well-defined lacunae or structured vascular pattern, in most of the Kaposi's sarcoma lesions. The most frequent dermoscopic patterns in Kaposi's sarcoma were found to be bluish-reddish coloration, the 'rainbow pattern', and scaly surface. The rainbow pattern is a dermoscopic feature which has not been previously described. We propose that dermoscopy, as an adjunct to clinical examination, may enhance accuracy in the preoperative diagnosis of Kaposi's sarcoma.

    Desmoid-type fibromatosis (DF) is a rare monoclonal, fibroblastic proliferation characterised by a variable and often unpredictable clinical course. It may affect nearly all parts of the body including extremities, trunk and abdomen. Considering the variable clinical presentations, anatomic locations and biological behaviours, an individualised treatment approach is required. No established or evidence-based approach for the treatment of this neoplasm is available as of today. Therefore, we propose a consensus treatment algorithm based on a round table meeting bringing together sarcoma experts from the European Organisation for Research and Treatment of Cancer (EORTC) Soft Tissue and Bone Sarcoma Group (STBSG) with patient advocates from Sarcoma Patients EuroNet (SPAEN). The aim of the meeting was to develop - for the first time ever - a consensus approach based on professionals' AND patients' expertise. As a fundamental prerequisite, all patients should be discussed in a multidisciplinary setting in centres or professional networks with a specific expertise in the disease.

    Full Text Available Endometrial stromal sarcomas (ESS are rare endometrial tumours arising from stroma of endometrium i.e. connective tissue of endometrium rather than glands. Usually a pre-operative diagnosis is difficult. Total abdominal hysterectomy with bilateral salpingo-oophorectomy is main line of treatment. Adjuvant hormone therapy in the form of progesterones, GnRH analogues, aromatase inhibitors are effective for prevention of recurrences as these tumours are invariably positive for oestrogen & progesterone receptors. Surgical excision, radiotherapy, hormone therapy are recommended for recurrences. We report a 52 yrs widow with undifferentiated endometrial stromal sarcoma weighing 3.75 kg with a short history of 3 months diagnosed only after histopathology.

    Different types of malignant tumors can occur within the thyroid. Primary cancer is the most common type of thyroid malignancy. Non-epithelial malignancies can also arise within the thyroid. The aim of the present study was to analyze clinical and radiological characteristics of reported primary thyroid sarcomas (PTS), based on a large sample of cases. The PubMed database was screened for articles from between 1990 and 2014. Overall, 86 articles with 142 patients were identified. Ultrasound evaluation was reported for 36 patients. Data regarding computed tomography of the neck were available for 29 cases. Magnetic resonance imaging was performed for eight patients. The following data were retrieved for the identified sarcomas: localization, size, homogeneity, internal texture, and margin characteristics. In most cases, PTS occurred in patients over 40 years of age, with a peak incidence for the group aged 60-79 years. Angiosarcoma was diagnosed in 29 cases (20.4%), followed by malignant hemangioendothelioma (n=23, 16.3%), malignant fibrous histiocytoma (n=20, 14.1%), leiomyosarcoma (n=16, 11.3%), and fibrosarcoma (n=13, 9.2%). In most patients (n=113, 79.6%), PTS manifested clinically as a painless goiter. On ultrasound, PTS were predominantly mixed hypo-to-hyperechoic in comparison to the normal thyroid tissue. On non-contrast computed tomography, most sarcomas were inhomogeneous hypo-to-hyperdense. On post-contrast magnetic resonance images, most sarcomas showed marked non-homogenous enhancement. In 26.8%, infiltration of the adjacent organs was seen. The trachea or esophagus was affected more frequently in patients with malignant histiocytoma and liposarcoma. Different strategies were used in the treatment of PTS. Our analysis provides clinical and radiological characteristics of PTS. The described features should be taken into consideration in the differential diagnosis of thyroid tumors.

    Purpose: Soft-tissue sarcomas of the retroperitoneum are rare tumors comprising less than 1% of all malignancies. Although surgery continues as the mainstay of treatment, the large size of these tumors coupled with their proximity to critical structures make resection with wide margins difficult to achieve. The role and timing of radiotherapy are controversial. This study updates our institutional experience using multimodality local therapy for resectable retroperitoneal sarcoma and identifies prognostic factors impacting disease control and survival. Methods and Materials: Between 1974 and 2007, 58 patients with nonmetastatic retroperitoneal sarcoma were treated with surgery and radiation at University of Florida. The median age at radiotherapy was 57 years old (range, 18-80 years). Forty-two patients received preoperative radiotherapy and 16 received postoperative radiotherapy. Nineteen patients received 1.8 Gy once daily and 39 patients received 1.2 Gy twice daily. Variables analyzed for prognostic value included age, grade, kidney involvement, histology, de novo versus recurrent presentation, tumor diameter, margin status, radiotherapy sequencing (preoperative vs. postoperative), total radiation dose, fractionation scheme, and treatment era. Results: The 5-year overall survival, cause-specific survival, and local control rates were 49%, 58%, and 62%, respectively. Nearly two-thirds of disease failures involved a component of local progression. On multivariate analysis, only margin status was significantly associated with improved 5-year local control (85%, negative margins; 63%, microscopic positive margins; 0%, gross positive margins; p < 0.0001) and 5-year overall survival (64%, negative margins; 56%, microscopic positive margins; 13%, gross positive margins; p = 0.0012). Thirty-one Grade 3 or greater toxicities were observed in 22 patients, including two treatment-related deaths (3%). Conclusion: For retroperitoneal sarcoma, local control remains a

    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.

    Childhood cancer survivors are at an increased risk of obesity but causes for this elevated risk are uncertain. We evaluated total energy expenditure in childhood cancer survivors using the doubly labeled water method in a cross-sectional study of 17 survivors of pediatric leukemia or lymphoma (median age, 11.5 y). Mean total energy expenditure was 2073 kcal/d, which was nearly 500 kcal/d lower than estimated energy requirements with recommended levels of physical activity. This energy gap is likely to contribute to the risk of obesity in this population and future trials are needed to assess implications and potential treatment strategies.

    Although there is no consensus regarding the optimal sequencing of external beam radiotherapy and surgery for extremity soft tissue sarcoma, radiation therapy delivered before or after limb-sparing surgery significantly improves local control, particularly for high-grade tumors. Large database analyses suggest that improved local control may translate into an overall survival benefit. Best practices require ample communication between the radiation and surgical teams to ensure appropriate tissues are targeted, unnecessary radiation is avoided, and patients are afforded the best opportunity for cure while maintaining function. Modern experiences with intensity-modulated radiotherapy/image-guided radiation therapy suggest toxicity is reduced through field size reduction and precise targeting, improving the therapeutic ratio.

    Kaposi sarcoma (KS) is a multifocal vascular disease with uncertain histogenesis. It is characterized by clinical and histologic polymorphism. The "lymphangioma-like" variant is very uncommon, accounting for less than 5% of all cases. We report the case of a 76-year-old woman, HIV negative, with a 4-year history of classic Kaposi sarcoma treated with cryotherapy who developed new bullous lesions on her lower extremities. Biopsy revealed histologic findings of lymphangioma-like KS (LLKS), together with areas of classic KS; HHV-8 staining was positive. Diagnosis of LLKS was made and the patient was proposed for radiotherapy. The lymphangioma-like Kaposi sarcoma is a rare morphologic expression of KS characterized by dilated and bizarrely shaped vascular channels lined by flattened endothelium permeating the dermis. "Bulla-like" lesions have been considered as a clinical hallmark of this variant. Its histologic appearance suggests a lymphatic origin of KS and it may resemble other vascular tumors. Findings of areas of typical KS and positive staining for HHV-8 may help to make a definitive diagnosis.

    Full Text Available 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.

    Kaposi sarcoma (KS) is an unusual vascular tumour caused by an oncogenic-herpesvirus, Kaposi sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV 8). KS lesions are characterized by an abundant inflammatory infiltrate, the presence of KSHV-infected endothelial cells that show signs of aberrant differentiation, as well as faulty angiogenesis/ vascularization. Here we discuss the molecular mechanisms that lead to the development of these histological features of KS, with an emphasis on the viral proteins that are responsible for their development.

    Organizational downsizing was a pervasive feature of the U.S. economy during the 1980s and 1990s. A long-standing public health literature recognizes that unemployment and job loss may adversely affect health, but there has been little attention to date on the impact of downsizing upon those who survive job cuts and continue to work in downsized firms. Drawing on research with survivors of downsizing carried out by the U.S. Department of Energy, this article identifies a variety of social and psychological consequences of downsizing that fundamentally destabilize the work environment and work experience for remaining employees. Evidence from this research suggests that the work climate of the post-downsizing environment is laden with suspicion and conflict, and that survivors show feelings of demoralization, sadness, anxiety, and disorientation. A critical factor influencing these responses, we argue, is not downsizing - which is the exposure faced by those who lose their jobs - but the loss of social cohesion that downsizing ultimately represents to survivors. We conclude that addressing the trauma of downsizing for survivors will require providing employees with more genuine opportunities to participate in workplace governance.

    BCOR-CCNB3 fusion transcripts resulting from an X-chromosomal paracentric inversion were recently identified in a series of unclassifiable soft tissue and bone sarcomas with Ewing sarcoma-like morphology. The morphologic and clinical features of these sarcomas are, as yet, not well characterized. Here we describe the clinicopathologic features of 10 cases of BCOR-CCNB3 sarcoma and compare their clinical course with typical Ewing sarcoma. Nine of 10 patients were male, and all were 11 to 18 years of age. Seven tumors were located in the bone and 3 in the deep soft tissues. The histomorphologic spectrum was quite wide, with 7 tumors predominately showing small primitive cell morphology with angulated nuclei simulating so-called atypical Ewing sarcoma and 3 predominately showing spindle cell morphology. Recurrent and metastatic lesions showed increased cellularity and marked pleomorphism. Immunohistochemistry showed expression of CCNB3 (100%), bcl2 (90%), CD99 (60%), and CD117 (60%). Reverse transcription polymerase chain reaction for BCOR-CCNB3 fusion transcripts was positive in all 9 cases, which yielded sufficient extracted RNA. Five- and 10-year survival rates were 75% and 56%, respectively. BCOR-CCNB3 sarcomas located in axial skeleton and soft tissues showed a significantly shorter survival. The Ewing sarcoma overall survival was not statistically different, although there was a trend for longer survival of patients with BCOR-CCNB3 sarcomas in the extremities. In conclusion, this study provides a detailed description of the histologic spectrum, immunohistochemical features, and clinical characteristic of BCOR-CCNB3 sarcoma justifying distinction from Ewing sarcoma with its typical EWS/FUS-ETS translocations. Ideally immunohistochemistry is used in combination with reverse transcription polymerase chain reaction for definitive diagnosis.

    Iliotibial band friction syndrome is a common entity that is often quickly diagnosed in orthopedic clinics. However, synovial sarcoma is an elusive clinical entity that appears around many joints with variable presentations. This case report is an example of a patient with a classic presentation of iliotibial band friction syndrome that was diagnosed as a synovial sarcoma on further investigation.

  20. Is There a Predisposition Gene for Ewing's Sarcoma?

    2010-01-01

    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.

    Conclusions and importance: The authors postulate emboli from the left atrial sarcoma entered systemic circulation and subsequently caused brief episodes of transient occlusion to retinal, ophthalmic and/or ciliary arteries leading to momentary retinal hypoxia. We believe this is a novel finding, previously unreported in the literature, of transient embolic occlusion without permanent visual sequelae due to a malignant primary cardiac pleomorphic sarcoma.

    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.

    Better diagnostic biomarkers and therapeutic options are still necessary for patients with sarcomas due to the current limitations of diagnosis and treatment. Exosomes are small extracellular membrane vesicles that are released by various cells and are found in most body fluids. Tumor-derived exosomes have been proven to mediate tumorigenesis, intercellular communication, microenvironment modulation, and metastasis in different cancers, including in sarcomas. Recently, exosomes have been considered as potential biomarkers for sarcoma diagnosis and prognosis, and as possible targets for sarcoma therapy. Moreover, due to their specific cell tropism and bioavailability, exosomes can also be engineered as vehicles for drug delivery. In this review, we discuss recent advances in the roles of tumor-derived exosomes in sarcoma and their potential clinical applications.

    The third medical examination of A-bomb survivors residing in the U.S. was performed in San Francisco, Los Angeles, Seattle and Honolulu during the period 6 - 28 May 1981. The test results were studied and the actual state of the survivors in the U.S., was reviewed as explained hereunder. 1) The number of survivors actually registered with the Committee of A-bomb Survivors in the U.S. is 491 (133 males and 358 females) of whom 57.2% are U.S. citizens. Those exposed in Hiroshima accounted for 91.8%. The mean age was 53.3 +- 8.9, thus they were more than 3 years younger than their counterparts in Hiroshima. The present addresses of the survivors are distributed over 15 states, but those in California constitute 77.6% of the total, and when those residing in the states along the west coast and Hawaii are added the rate increases to 95.9%. 2) Those who underwent health examination numbered 166 (45 males and 121 females), and comparison of the U.S. survivors against the Hiroshima survivors showed there to be a difference in the following points. The prevalence of hypertension was lower among the U.S. survivors, but RBC counts and hemoglobin concentration were significantly higher. The same was observed for blood lipids with hypercholesterolemia and hypertriglyceridemia being found at a significantly higher rate in the U.S. survivors. 3) Those free of clinical abnormalities in this survey were 37.3%, and the rest required dietary guidance, follow-up observation, detailed examination of treatment. Those with diseases which are considered would make them eligible for health management allowance if in Japan, accounted for 18.7%.

    Directory of Open Access Journals (Sweden)

    Michitaka Kato

    2015-01-01

    Full Text Available Myxoinflammatory fibroblastic sarcoma (MIFS is a rare, painless, and intermediate (rarely metastasizing fibroblastic tumor, which commonly occurs in the extremities, with an equal sex predilection. This sarcoma is composed of a mixed inflammatory infiltrate along with spindled, epithelioid, and bizarre tumor cells in a background of hyaline and myxoid areas. In spite of such a distinctive morphology, the tumor can be a diagnostic challenge, simulating inflammatory conditions as well as neoplastic nature. For accurate diagnosis, the tumor requires extensive clinical, radiological, and pathological investigations. We present a case of MIFS in a 19-year-old female who presented with a mass in the left ankle. After appropriate excision and postoperative radiation therapy, she is free of disease, including recurrence and metastasis, at 12 years postoperatively.

    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.

    Pazopanib is a multitargeted tyrosine kinase inhibitor approved for the treatment of patients with selective subtypes of advanced soft tissue sarcoma (STS) who have previously received standard chemotherapy including anthracyclines. Data on the efficacy in vascular sarcomas are limited. The main objective of this study was to investigate the activity of pazopanib in vascular sarcomas. A retrospective study of patients with advanced vascular sarcomas, including angiosarcoma (AS), epithelioid hemangioendothelioma (HE) and intimal sarcoma (IS) treated with pazopanib in real life practice at EORTC centers as well as patients treated within the EORTC phase II and III clinical trials (62043/62072) was performed. Patient and tumor characteristics were collected. Response was assessed according to RECIST 1.1. and survival analysis was performed. Fifty-two patients were identified, 40 (76.9%), 10 (19.2%) and two (3.8%) with AS, HE and IS, respectively. The response rate was eight (20%), two (20%) and two (100%) in the AS, HE and IS subtypes, respectively. There was no significant difference in response rate between cutaneous and non-cutaneous AS and similarly between radiation-associated and non-radiation-associated AS. Median progression-free survival (PFS) and median overall survival (OS; from commencing pazopanib) were three months (95% CI 2.1-4.4) and 9.9 months (95% CI 6.5-11.3) in AS, respectively. The activity of pazopanib in AS is comparable to its reported activity in other STS subtypes. In this study, the activity of pazopanib was similar in cutaneous/non-cutaneous and in radiation/non-radiation-associated AS. In addition, pazopanib showed promising activity in HE and IS, worthy of further evaluation.

    2015-04-01

    To examine the psychosocial problems of childhood cancer survivors in Korea and investigate whether such problems are influenced by family management style. Family members of 158 childhood cancer survivors answered a questionnaire on demographic and illness characteristics, described psychosocial problems in their children using the Pediatric Symptom Checklist (PSC), and completed the Family Management Measure (FaMM). Perceived economic status and all six subscales of the FaMM were significantly correlated with children's psychosocial problems. In a multiple regression model, the Family Life Difficulty and Parental Mutuality scales of the FaMM were each independent predictors of psychosocial problems in young cancer survivors. A detailed care plan designed to (1) promote balance between the management of a child's condition and normal family life and (2) encourage parents to share their feelings with one another and provide mutual support should be required to improve psychosocial outcomes for childhood cancer survivors.

    Background A high proportion of pediatric cancer patients are now surviving into adulthood, but are at increased risk for late morbidity and premature mortality related to their diagnosis and therapeutic exposures. Little is known about the potential success of recruiting adult survivors of childhood cancer into research projects that would require a risk-based health evaluation within a clinical setting. Procedures Pediatric cancer survivors and siblings eligible for the current study were Childhood Cancer Survivor Study participants who lived within 100 miles of one of five Consortium for Pediatric Intervention Research institutions, regardless of where they were initially diagnosed and treated. A short survey was mailed to 829 survivors and 373 siblings to identify factors that predict interest, potential barriers, and motivators, to participation in research including a risk-based clinical evaluation. Results Overall, 92% of survivors responding to the survey were very interested/interested in participating in a research study requiring a visit to a local hospital clinic. Siblings of survivors were less interested than survivors in participating in such a study, with only 78% indicating that they were very interested/ interested. Potential motivators to participation included visiting their treating hospital and receiving health information. The primary barrier to participation was related to taking time off from work. Conclusions This study demonstrates that a subgroup of survivors would be willing to return to a long-term follow-up center to participate in intervention-based research. Identified motivating factors and perceived barriers need to be considered in determining the feasibility, design and execution of future research. PMID:24976622

    Kaposi sarcoma is expressed in four clinical variants, all associated with human herpes virus type 8 infection, namely, classic, endemic, immunosuppression-related and AIDS-related. The latter currently accounts for most of the burden of Kaposi sarcoma in sub-Saharan Africa, reflecting the frequency of HIV infection and its management. We aimed to estimate the incidence of Kaposi sarcoma in Mozambique and in its provinces. We estimated the number of incident cases of Kaposi sarcoma by adding up the expected number of endemic and AIDS-related cases. The former were estimated from the rates observed in Kyandondo, Uganda (1960-1971). The latter were computed from the number of AIDS-related deaths in each region, assuming that the ratio between the AIDS-related Kaposi sarcoma incident cases and the number of AIDS-related deaths observed in the city of Beira applies to all regions. A total of 3862 Kaposi sarcoma cases were estimated to have occurred in Mozambique in 2007, mostly AIDS-related, in the age group 25-49 years, and in provinces from South/Centre. The age-standardized incidence rates were 36.1/100 000 in men and 11.5/100 000 in women, with a more than three-fold variation across provinces. We estimated a high incidence of Kaposi sarcoma in Mozambique, along with large regional differences. These results can be used to improve disease management and to sustain political decisions on health policies.

    Suicide bereavement is frequently related to clinically significant psychological distress and affected by stigma. This study was designed to evaluate the relationship between psychological distress by psychopathological domains and stigma, in a sample of individuals bereaved by suicide (suicide survivors). The data were collected between January 2012 and December 2014 and included information on sociodemographic variables (gender, age, marital status and education level) and responses to the Stigma of Suicide Survivor scale (STOSSS) and the Brief Symptom Inventory (BSI). One hundred and fifty-five suicide survivors completed the evaluation and were included in the study. Levels of psychological distress in suicide survivors, as measured by BSI, were positively related to levels of perceived stigma toward suicide survivors, as measured by STOSSS. The association was not affected by age and gender, or by marital status, education level, days from suicide or a personal history of suicide attempt. Participants with higher scores on almost all subscales of the BSI, particularly the interpersonal sensitivity and paranoid ideation subscales, reported the highest levels of perceived stigma toward suicide survivors. Levels of distress in subjects bereaved by the suicide of a relative or friend were positively associated with levels of perceived stigma toward suicide survivors. Specific interventions dedicated to the bereavement of suicide survivors might help to alleviate not only psychological distress but also stigma towards loss by suicide.

    Pulmonary involvement in Kaposi sarcoma is rare in children and can be difficult to distinguish from other pathology. To describe the radiological findings in paediatric pulmonary Kaposi sarcoma. Sequential chest radiographs of six children and CT scans of four of these children were evaluated retrospectively. Their ages ranged from 18 months to 10 years; four were male and two were female. All six children were HIV-positive. The observers were two radiologists. Chest radiographs revealed air-space (100%) and reticular (83%) opacification in the mid- and lower lung zones; pleural effusions were present in 83% of the children. All the children showed progressive air-space opacification on follow-up radiography. CT demonstrated bilateral air-space opacification in a perihilar distribution in all the children; reticular opacification was seen in 75%. All the children had mediastinal and axillary lymphadenopathy; 75% had bilateral hilar lymphadenopathy. In both adults and children, chest radiography demonstrates perihilar and lower zone involvement. Pleural effusions are more common on radiographs in children. Air-space disease and lymphadenopathy are much more common on CT in children than adults. (orig.)

    A 28-year-old man presented with a histiocytic sarcoma of a very uncommon origin, as it had developed for several years like a benign cutaneous histiocytosis resembling generalized eruptive histiocytoma before becoming acute, with nodal and massive pulmonary involvement. Despite various chemotherapies, the patient died within 8 months. Skin biopsies showed histiocytic proliferation in the dermis and node biopsies showed histiocytic proliferation with a sinusoidal pattern. Immunohistochemical analysis, performed on paraffin-embedded sections, demonstrated strong labeling of tumoral cells for CD68 and moderate labeling for CD3 and CD4. CD30 labeling was negative. S-100 protein was positive on a Langerhans' cell reactive subpopulation. Electron microscopy confirmed the histiocytic nature of malignant cells and showed cytoplasmic inclusions such as regularly laminated bodies, dense bodies and pleomorphic inclusions. No Birbeck granules were seen. A gene rearrangement study of T-cell receptor gamma and immunoglobulin heavy chain genes showed a germline configuration. Histiocytic sarcoma is an extremely rare true histiocytic malignancy, the existence of which has been recently debated since it has often been mistaken in the past for large cell lymphomas. Such a deceptive onset as benign cutaneous histiocytosis has not been described in the literature to our knowledge.

    Full Text Available Endometrial Stromal Sarcoma (ESS is a rare slow growing tumour of mesodermal origin arising from the stroma of the endometrium and accounting for less than 1% of all uterine cancers. It is characterized by late recurrences and distant metastases. This report presents a case of ESS in a 40 year old nulliparous woman who had a myomectomy for a clinically suspected Leiomyoma uterus in a local hospital. The histopathological examination of the specimen revealed ESS and the patient was referred to our tertiary institute. Here after investigations including a CT scan which also revealed pulmonary metastases, patient underwent Modified Radical Hysterectomy with Bilateral Salpingo-oophorectomy with pelvic lymph node sampling. Histopathological Examination of the uterine specimen confirmed the diagnosis. The patient was given the option of referral to a thoracic surgeon for resection of the isolated lung metastasis, but she refused this and opted instead for hormone therapy which she is presently undergoing. ESS is a very rare tumour often presenting with clinical and examination findings suggestive of leiomyoma of the uterus and hence misdiagnosed. In cases of rapidly growing tumours and suspicious radiological features, suspect sarcoma and initiate timely diagnosis and proper treatment. Recommended long-term follow up in view of late recurrences. [Int J Reprod Contracept Obstet Gynecol 2014; 3(3.000: 812-815

    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

    The study was performed to present the sonographic findings of uterine endometrial stromal sarcoma (ESS). We conducted a retrospective review of sonographic findings of 10 cases that were diagnosed as uterine ESS. The patients ages ranged from 25 to 51 years (mean age: 36.1 years). The reviews focused on the location, margin, size, number and echotexture of the lesions. Hysterectomy (n = 9) and myomectomy (n = 1) were performed and a pathologic diagnosis was obtained in all cases. The masses were located in the uterine wall (n = 6), or they presented as a polypoid mass protruding into the endometrial cavity from the myometrium (n = 3) or as a central cavity mass (n = 1). The lesion margins were smooth (n = 5), ill defined (n = 2), or smooth with partially nodular extensions (n = 3). The maximal mass length was 38 mm to 160 mm with a mean mass length of 83.5 mm. There were single lesions in eight cases and multiple lesions in two cases. The lesion echotextures were hypoechoic solid (n = 3), heterogeneously intermediate echoic (n = 5), diffuse myometrial thickening with heterogeneous echogenicity (n = 1) and septated cystic (n = 1). Endometrial stromal sarcoma presents with four patterns of its sonographic appearance; a polypoid mass with nodular myometrial extension, an intramural mass with an ill defined margin and heterogeneous echogenicity, an ill defined large central cavity mass or, diffuse myometrial thickening.

    Synovial sarcoma (SS), a mesenchymal spindle cell tumor, displays variable epithelial differentiation, including glandular formation, and features a specific chromosomal translocation, t(X;18)(p11;q11). SS accounts for 5% to 10% of soft-tissue sarcomas. These tumors occur mostly in the joints, especially near the knee, but they also occur in other locations. Primary intravascular SS (IVSS) are extremely rare; only 6 well-documented cases have been reported in the English literature. We describe a new case of primary IVSS of the superior vena cava (SVC) in a 16-year-old boy. A transthoracic echocardiogram confirmed a large (4.8 × 4.6 cm) circumscribed mass filling the right atrium, as well as a moderate pericardial effusion. The mass extended from the SVC to the tricuspid valve but did not prevent valve coaptation. Surgery via a transatrial approach revealed a huge mass (8 to 12 cm) attached to the SVC via a 5-mm pedicle. The tumor was excised, and the patient experienced an uneventful postoperative course. Fluorescence in situ hybridization analysis revealed the presence of the SS-specific translocation.

  10. Multidisciplinary Management of Soft Tissue Sarcoma

    2013-01-01

    Full Text Available Soft tissue sarcoma is a rare malignancy, with approximately 11,000 cases per year encountered in the United States. It is primarily encountered in adults but can affect patients of any age. There are many histologic subtypes and the malignancy can be low or high grade. Appropriate staging work up includes a physical exam, advanced imaging, and a carefully planned biopsy. This information is then used to guide the discussion of definitive treatment of the tumor which typically involves surgical resection with a negative margin in addition to neoadjuvant or adjuvant external beam radiation. Advances in imaging and radiation therapy have made limb salvage surgery the standard of care, with local control rates greater than 90% in most modern series. Currently, the role of chemotherapy is not well defined and this treatment is typically reserved for patients with metastatic or recurrent disease and for certain histologic subtypes. The goal of this paper is to review the current state of the art in multidisciplinary management of soft tissue sarcoma.

    Full Text Available The case was a 40-year-old female. She visited a local doctor with a chief complaint of right side abdominal pain. A right kidney tumor measuring 10 cm in diameter was observed in an abdominal Computed Tomography (CT scan. Based on the CT image, the possibility of angiomiolipoma (AML could not be ruled out, but a high maximum standardized uptake value (SUVmax of 7.8 was observed in a Positron Emission Tomography CT (PET-CT scan and there was a possibility of malignancy. We therefore performed a transperitoneal right radial nephrectomy. Although adhesion of the tumor to the duodenum and the inferior vena cava was observed, it was possible to perform an excision. The tumor accounted for a large proportion of the excised kidney; the surrounding areas had taken on a cyst-like structure, and the interior comprised grayish brittle tissue exhibiting solid growth. Histologically, gland-like and cyst-like structures composed of cylindrical cuboidal cells and mainly characterized by the solid growth of short fusiform-shaped and oval-shaped basophilic cells were observed, and we believed it was a synovial sarcoma. There were no malignant findings in the adrenal gland. There have been approximately 30 reported cases around the world of synovial sarcoma that developed in the kidney, and we herein report this case with bibliographic considerations.

    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.

    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.

    EZH2 is a component of the epigenetic regulator PRC2 that suppresses gene expression. Elevated expression of EZH2 is common in human cancers and is associated with tumor progression and poor prognosis. In this study, we show that EZH2 elevation is associated with epigenetic modifications of Kaposi sarcoma-associated herpesvirus (KSHV), an oncogenic virus that promotes the development of Kaposi sarcoma and other malignancies that occur in patients with chronic HIV infections. KSHV induction of EZH2 expression was essential for KSHV-induced angiogenesis. High expression of EZH2 was observed in Kaposi sarcoma tumors. In cell culture, latent KSHV infection upregulated the expression of EZH2 in human endothelial cells through the expression of vFLIP and LANA, two KSHV-latent genes that activate the NF-κB pathway. KSHV-mediated upregulation of EZH2 was required for the induction of Ephrin-B2, an essential proangiogenic factor that drives endothelial cell tubule formation. Taken together, our findings indicate that KSHV regulates the host epigenetic modifier EZH2 to promote angiogenesis.

    Full Text Available Kaposi sarcoma (KS is a low-grade mesenchymal tumor involving blood and lymphatic vessels. There are four types, based on clinical presentation: classic, endemic (Africana, iatrogenic (typically, involving renal allograft recipients, and AIDS-associated (epidemic. Kaposi's sarcoma-associated herpes virus infection has been linked along with other factors to the development of KS. The Kaposi's sarcoma-associated herpes virus interacts and encodes for numerous molecular proteins that play a role in the pathogenesis of KS, including latency-associated nuclear antigen, viral G protein-coupled receptor, viral FLICE inhibitory protein, and viral IL-6. KS primarily affects the skin and causes disseminated disease in a variety of organs. Involvement of visceral organs other than the lining of the alimentary tract is extremely rare. While the chylous pleural effusions of KS may resemble other pulmonary diseases (including lymphangioma, lymphangectasis, and lymphangioleiomyomatosis with chylous effusions at thoracic CT, differentiating features may allow for more prompt diagnosis and treatment. The presumptive diagnosis of AIDS-related pulmonary KS is often clinical. A tissue diagnosis is not required to establish the diagnosis of pulmonary KS. There are a variety of causes of chylothorax. The primary finding is a near-water-attenuating pleural effusion. The secondary findings of chylothorax can help differentiate the etiology.

    2010-01-01

    Full Text Available Radiotherapy (RT is our preferred modality for local palliation of metastatic soft tissue sarcoma (STS. A short and intense course of RT is usually needed for rapid palliation and local control of metastatic disease. Seventeen patients at a median age of 61 had symptomatic metastatic sarcoma and required rapid palliation. The symptoms related to the metastases were either pain or discomfort. All patients were treated by a short and intensive course of administration: 39 Gy were given in 13 fractions of 3 Gy/day, 5 times a week. Median follow-up period was 25 weeks. The treatment was well tolerated. Acute side effects included grade one skin toxicity. No wound complications were noted among those undergoing surgery. Late side effects included skin pigmentation and induration of irradiated soft tissues. Durable pain control was achieved in 12 out 15 cases treated for gross metastases. Tumor progression was seen in the 3 other cases within a period of two to nine months. Among 5 lesions which were irradiated as an adjunctive treatment following resection, no local recurrence was observed. The results of this series, although limited in size, point to the safety and feasibility of hypofractionated RT for palliation of musculoskeletal metastases from sarcoma

    Full Text Available Background. Angiotensin-(1-7 [Ang-(1-7] is an endogenous antiangiogenic hormone with anticancer activity. In a phase I study of Ang-(1-7, two of three patients with metastatic sarcoma experienced disease stabilization. This phase II study examined clinical and biomarker outcomes for patients with metastatic sarcoma. Methods. Ang-(1-7 was administered by subcutaneous injection at a dose of 20 mg daily. If excessive toxicities occurred in the first cohort, a dose deescalation cohort was allowed. Blood samples were obtained to measure changes in biomarkers. Results. Treatment was well-tolerated and the dose deescalation cohort was not required. Plasma PlGF concentrations following treatment were not statistically significantly changed. A significant increase in plasma Ang-(1-7 was observed at 4 hours after injection. The median progression-free survival was 2.7 months (95% CI; 1.4 to 4.1 months, and the median overall survival was 10.2 months (95% CI; 5.3 to 18.3 months. Two patients with vascular sarcomas demonstrated prolonged disease stabilization of 10 months (hemangiopericytoma and 19 months (epithelioid hemangioendothelioma. Conclusions. Ang-(1-7 at a dose of 20 mg daily was well-tolerated. This prospective phase II study failed to confirm the PlGF biomarker effect identified in the prior phase I study. Prolonged disease stabilization in hemangiopericytoma and epithelioid hemangioendothelioma may warrant further investigation.

  18. The clinician's perspective on sarcoma pathology reporting: impact on treatment decisions?

    2014-02-01

    The current refinement of nosological classification of sarcoma which integrates molecular typing with a growing number of subtypes contrasts with the one-size-fits-all approach proposed in clinical practice guidelines for both local treatment and systemic treatment in the past. However, there is a growing proportion of sarcomas in which specific treatment strategies are proposed as standard. As a consequence, central review by expert sarcoma pathologists should be organised to ensure the optimal management of all patients. The key parameters in the pathology report influencing treatment decisions are therefore rapidly evolving. First a diagnostic biopsy, ideally an imaged guided microbiopsy performed by an experienced team, is a recommended practice. On the resection specimen, the size, histological grade, location, depth, surgical margins and tumour fragmentation are essential parameters to guide the treating physician. Molecular characterisation of the driving genomic event is becoming increasingly important for treatment decision making, in routine practice and in clinical trials. Molecular grade is a research tool with potentially high utility, and requires further evaluation and validation in prospective clinical trials.

    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.

    Primary nasopharyngeal Kaposi sarcoma is extremely rare, as only 1 case has been previously reported in the literature. We report a new case, which occurred in a 37-year-old man with a known history of acquired immune deficiency syndrome (AIDS). The patient presented with complaints of recurrent epistaxis and postnasal hemorrhage. Endoscopic examination detected a bluish, smooth, firm, nonpulsatile mass in the nasopharyngeal wall. Histopathologic findings on biopsy were consistent with Kaposi sarcoma. The tumor was successfully treated with radiotherapy. Kaposi sarcoma should be considered in the differential diagnosis of any AIDS patient who presents with recurrent unilateral nasal bleeding.

    Pseudo-Kaposi sarcoma is a benign reactive vascular proliferative disorder, which can be seen at any age. It occurs when the chronic venous pressure changes result in vascular proliferation in the upper and mid dermis. This disease is divided into two subtypes: the most frequent subtype is the Mali type and seen in early ages. The Mali type is seen in chronic venous insufficiency and in those patients with arteriovenous shunts. The rare subtype is the Stewart-Bluefarb type. This disease must be distinguished from Kaposi sarcoma because of their clinical resemblance. Herein, we present a patient with pseudo-Kaposi sarcoma, which developed after bullous erysipelas.

    Myeloid sarcoma manifesting as multiple lymphadenopathy is quite rare. We present here a case of myeloid sarcoma that first presented with palpable bilateral neck masses. A 53-year-old woman complained about repetitive swelling in the right infraauricular and submental areas for 3 years. The results of computed tomography showed multiple lymphadenopathy in both areas of the neck as well as other parts of the body. So, the presumptive diagnosis was lymphoma, but the result of the excisional biopsy of the neck mass confirmed it to be a myeloid sarcoma.

    Kaposi sarcoma (KS) is a virus-related malignancy which most frequently arises in skin, though visceral sites can also be involved. Infection with Kaposi sarcoma herpes virus (KSHV or HHV-8) is required for development of KS. Nowadays, most cases worldwide occur in persons who are immunosuppressed, usually because of HIV infection or as a result of therapy to combat rejection of a transplanted organ, but classic Kaposi sarcoma is predominantly a disease of the elderly without apparent immunosuppression. We analyzed 2667 KS incident cases diagnosed during 1995-2002 and registered by 75 population-based European cancer registries contributing to the RARECARE project. Total crude and age-standardized incidence rate was 0.3 per 100,000 per year with an estimated 1642 new cases per year in the EU27 countries. Age-standardized incidence rate was 0.8 per 100,000 in Southern Europe but below 0.3 per 100,000 in all other regions. The elevated rate in southern Europe was attributable to a combination of classic Kaposi sarcoma in some Mediterranean countries and the relatively high incidence of AIDS in several countries. Five-year relative survival for 2000-2002 by the period method was 75%. More than 10,000 persons were estimated to be alive in Europe at the beginning of 2008 with a past diagnosis of KS. The aetiological link with suppressed immunity means that many people alive following diagnosis of KS suffer comorbidity from a pre-existing condition. While KS is a rare cancer, it has a relatively good prognosis and so the number of people affected by it is quite large. Thus it provides a notable example of the importance of networking in diagnosis, therapy and research for rare cancers.

    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

  6. Organized Abuse in Adulthood: Survivor and Professional Perspectives.

    2017-02-23

    This paper reports on the preliminary findings of a qualitative study of Australian women disclosing organized abuse in adulthood and the mental health professionals who treat them. Drawing on interviews with survivors and mental health professionals, the paper analyses the fraught relationship between mental health and physical safety for adults subject to organized abuse. The therapeutic progress of adult organized abuse victims can be disrupted by ongoing threats, stalking, and group violence, which in turn reinforces the dissociative responses and pathological attachments that render them vulnerable to revictimization. The paper argues that breaking this cycle requires intervention from multiple agencies, and describes the responses of police, medical services, and child protection services to adult organized abuse from the perspective of survivors and mental health practitioners. Highlighting systemic failures but also opportunities, the paper calls for a coordinated response to organized abuse in adulthood, including inter-agency partnerships to support safety and bolster the efficacy of therapeutic interventions.

    2008-01-01

    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.

    Breast cancer survivors experience a range of sexual health (SH) issues. Communication problems between patient and provider can prevent survivors from pursuing SH goals and can negatively influence biopsychosocial outcomes. The primary aims of this study were to identify provider communication behaviors that facilitate or impede clinical interactions regarding SH (according to survivors and providers) and to highlight discrepancies that affect care. Forty breast cancer survivors and forty health care providers from a variety of specialties participated in semi-structured interviews informed by the Critical Incident Technique. Transcripts were thematically analyzed using the constant comparative method. Survivors and providers discussed the importance of honoring individual patient needs and conveying compassionate messages. However, accounts varied significantly regarding the appropriate timing and method of initiating SH discussions and the helpfulness of certain support behaviors and linguistic devices. Provider and survivor accounts of what constitutes helpful and unhelpful provider communication behaviors when discussing SH concerns are misaligned in nuanced and meaningful ways. These discrepancies reveal potential areas for educational intervention. SH discussions require providers to examine assumptions about patients' communication preferences and information needs. Patients may benefit from frank yet sensitive discussions earlier in the cancer continuum. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    To synthesize the qualitative research evidence that explored how survivors of adult spinal cord injury experience and make sense of resilience. Spinal cord injury is often a sudden and unexpected life-changing event requiring complex and long-term rehabilitation. The development of resilience is essential in determining how spinal cord injury survivors negotiate this injury and rehabilitation. A qualitative systematic review and thematic synthesis of the research evidence. CINAHL, PubMed, Embase, Scopus and PsycINFO were searched, no restriction dates were used. Methodological quality was assessed using the Critical Appraisal Skills Programme checklist. Thematic synthesis focused on how survivors of adult spinal cord injury experience and make sense of resilience. Six qualitative research articles reported the experiences of 84 spinal cord injury survivors. Themes identified were: uncertainty and regaining independence; prior experiences of resilience; adopting resilient thinking; and strengthening resilience through supports. Recovery and rehabilitation following spinal cord survivors is influenced by the individual's capacity for resilience. Resilience may be influenced by previous life experiences and enhanced by supportive nursing staff encouraging self-efficacy. Survivors identified the need for active involvement in decision-making about their care to enable a sense of regaining control of their lives. This has the potential to have a significant impact on their self-efficacy and in turn health outcomes. © 2017 John Wiley & Sons Ltd.

    The overall aim of the proposed study is to examine a newly implemented navigation intervention intended to support stroke survivors' community integration during the first year following hospital discharge in four regions of Ontario, Canada. Stroke is a leading cause of disability worldwide. Stroke survivors living in the community require regular, ongoing follow-up to assess recovery, prevent deterioration and maximize health outcomes. Internationally published evidence, often conducted in large urban centres, suggests that community reintegration services are an important component of the continuum of care for stroke survivors. This evidence, however, often does not address the particular challenges inherent in smaller urban and rural contexts. The design of this 2-year mixed-method study will use cohort and focused ethnography. The three stages of this study include: (1) collection of quantitative data to profile the health status, support and extent of community reintegration of stroke survivors; (2) collection of qualitative data from stroke survivors and their care partners about community reintegration and navigation; and following triangulation of findings (3) knowledge translation activities. This study was ethically approved by the academic Research Ethics Board and clinical Research Ethics Board (Sudbury, Ontario) and funded by the Ontario Stroke Network (Canada). Results will describe experiences and outcomes of a community navigation intervention. Engagement of multiple stakeholders has the potential to develop a shared understanding of community reintegration and generate evidence informed recommendations for service enhancement at critical points in stroke recovery to support survivor and community well-being. © 2014 John Wiley & Sons Ltd.

  12. Kaposi's Sarcoma-Associated Herpesvirus K-bZIP Protein Is Necessary for Lytic Viral Gene Expression, DNA Replication, and Virion Production in Primary Effusion Lymphoma Cell Lines▿ †

    Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of three human proliferative disorders, namely, Kaposi's sarcoma, primary effusion lymphomas (PEL), and multicentric Castleman's disease. Lytic DNA replication of KSHV, which is essential for viral propagation, requires the binding of at least two KSHV proteins, replication and transactivation activator (RTA) and K-bZIP, on the lytic origin of replication. Moreover, K-bZIP physically interacts with RTA and represses its tra...

    A histopathologic review of F344 rat spleens from the National Toxicology Program-National Cancer Institute bioassays of barium salt of 5-chloro-2-(2-hydroxy-1-naphthalenyl)-azo-4-methylbenzenesulfonic acid [(D & C Red No. 9) CAS: 516-00-21] and aniline HCI (CAS: 142-04-1) was conducted to assess splenotoxic changes associated with splenic sarcomas induced by these aromatic amines. Four splenic changes--fatty metamorphosis (FM), splenic fibrosis (FIB), capsule hyperplasia (CH), and hemorrhage--were markedly increased in incidence and severity in males treated with high doses of either D & C Red No. 9 or aniline HCI. Females treated with high doses of either of these compounds showed similar but less severe changes. FIB and FM showed strong group correlations with tumor incidence (r greater than or equal to 0.87). All groups that demonstrated FM also demonstrated splenic sarcomas; groups without the FM lesions did not exhibit splenic tumors. The morphologic similarity of the FIB and CH lesions to the induced splenic sarcomas suggests that these lesions are preneoplastic. Moreover, the treatment-related splenic lesions appear to be precursors of the induced splenic sarcomas. Carcinogenicity studies with serial sacrifices at varying intervals will be required for experimental verification of these conclusions. A schema, based on the findings of the study, suggests a hypothetical pathway for the progression of the treatment-related splenic lesions from onset to tumor formation.

    Full Text Available Primary lung sarcomas are rare but aggressive tumors accounting for less than 0.5% of all lung tumors. The diagnosis of primary lung sarcoma should only be considered after exclusion of other sites. A 32-year-old female presented with recurrent hemorrhagic pleural effusions, shortness of breath and persistent cough. Pleural effusion was drained twice, and each time its analysis was normal. Patient developed atelectasis of left lung with hemothorax for which she underwent video-assisted thoracoscopic surgery. A large mass was found compressing the entire lower lobe of left lung with extension into mediastinum, the biopsy of which showed myxoid sarcoma. The tumor was inoperable and options of chemotherapy or radiotherapy were discussed with the patient. Primary lung sarcoma can rarely present with recurrent hemorrhagic pleural effusion. A high degree of suspicion is required for early diagnosis as large hemothorax on computed tomography or chest X-ray may obscure lung mass and make its diagnosis difficult.

    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.

    2015-11-21

    Soft-tissue sarcomas (STS) account for 1% of adult and 7% of pediatric malignancies. Histopathology and classification of these rare tumors requires further refinements. The aim of this paper is to describe the current incidence and survival of STS from 1994 to 2012 in Ireland and compare these with comparably coded international published reports. This is a retrospective, population study based on the data from the National Cancer Registry of Ireland (NCRI). Incidence and relative survival rates for STS in Ireland were generated. Incidence of STS based on gender, age and anatomical location was examined. Annual mean incidence rate (European Age Standardized) in Ireland between 1994 and 2012 was 4.48 ± 0.15 per 100,000 person-years. The overall relative 5-year survival rate of STS for the period 1994-2011 in Ireland was 56%, which was similar to that reported in the U.K. but lower than in most of Europe and U.S.A. Survival rate fluctuated over the period examined, declining slightly in females but showing an increase in males. STS incidence trends in Ireland were comparable to international reports. Survival trends of STS were significantly different between Ireland and other European countries, requiring further study to understand causation.

    Breast sarcoma is a rare condition. It consists of a heterogeneous group of non-epithelial tumours arising from the mesenchymal tissue of the breast. It has a distinctly different natural history, treatment response and prognosis as compared with carcinoma of the breast. A different diagnostic approach and treatment strategy have to be defined for this group of tumours. Due to its rarity, the current understanding on breast sarcoma is limited and is mostly based on small retrospective case series or case reports. Hence, the management generally follows the algorithms derived from randomised control trials of soft tissue sarcomas in the extremities and chest wall. Through this review, we discuss the results of major retrospective studies on breast sarcomas including data on epidemiology, aetiology, diagnostic approach, treatment strategies and outcomes of this challenging and potentially aggressive condition.

    2010-07-01

    Full Text Available Abstract Introduction Kaposi's sarcomas have been associated with different conditions of immunosuppression and are also known to be a typical complication of solid organ transplantations. Case presentation We report the case of a 65-year-old Turkish man with a history of heart transplantation 10 months ago who presented for clarification of his dyspnea. The patient had a known history of chronic obstructive pulmonary disease and a smoking history of 40 pack years. Radiologically, three progressively growing intra-pulmonary nodules were detected. The histology was diagnostic for a Kaposi's sarcoma. Visceral and especially primary intra-pulmonary Kaposi's sarcomas are very rare and have been described to have a rather unfavorable prognosis. Conclusions Even with a history suggestive for conventional lung cancer, Kaposi's sarcomas should be considered in patients after transplantation of solid organs. It should be noted that in a minority of cases this tumor exists in the absence of the typical cutaneous lesions.

    Full Text Available Ionizing radiation has been known to induce malignant transformation in human beings. Radiation-induced sarcomas are a late sequel of radiation therapy. Most sarcomas have been reported to occur after exposure to a radiation dose of 55 Gray (Gy and above, with a dose ranging from 16 to 112 Gys. Spindle cell sarcomas, arising after radiotherapy given to treat the carcinoma of head and neck region is a very uncommon sequel. This is a rare case report of spindle cell sarcoma of left maxilla, in a 24-year-old male, occurring as a late complication of radiotherapy with Cobalt-60 given for the treatment of retinoblastoma of the left eye 21 years back.

    Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age. A sex-matched and age-matched population-based control cohort was used for comparison (n=45,449). Demographic and socioeconomic data were obtained from national registers and explored by discrete-time Cox regression analyses. Childhood cancer survivors had a reduced rate of cohabitation [rate ratio (RR) 0.78; 95% confidence interval (CI): 0.73-0.83], owing to lower rates among survivors of both noncentral nervous system (CNS) tumors (RR 0.88; 95% CI: 0.83-0.95) and CNS tumors (RR 0.52; 95% CI: 0.45-0.59). Male CNS tumor survivors had a nonsignificantly lower rate (RR 0.47; 95% CI: 0.38-0.58) than females (RR 0.56; 95% CI: 0.47-0.68). The rates of separation were almost identical to those of controls. In conclusion, the rate of cohabitation was lower for all childhood cancer survivors than for the population-based controls, with the most pronounced reduction among survivors of CNS tumors. Mental deficits after cranial irradiation are likely to be the major risk factor.

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. Factors such as chemical agents, radiation, immunosuppression, and genetic syndromes and abnormalities are involved in their etiology. 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

    2011-01-01

    The p53 tumour suppressor plays a pivotal role in the prevention of oncogenic transformation. Cancers frequently evade the potent antitumour surveillance mechanisms of p53 through mutation of the TP53 gene, with approximately 50% of all human malignancies expressing dysfunctional, mutated p53 proteins. Interestingly, genetic lesions in the TP53 gene are only observed in 10% of Ewing Sarcomas, with the majority of these sarcomas expressing a functional wild-type p53. In addition, the p53 downs...

  15. Induction of histiocytic sarcoma in mouse skeletal muscle.

    Directory of Open Access Journals (Sweden)

    Jianing Liu

    Full Text Available Myeloid sarcomas are extramedullary accumulations of immature myeloid cells that may present with or without evidence of pathologic involvement of the bone marrow or peripheral blood, and often coincide with or precede a diagnosis of acute myeloid leukemia (AML. A dearth of experimental models has hampered the study of myeloid sarcomas and led us to establish a new system in which tumor induction can be evaluated in an easily accessible non-hematopoietic tissue compartment. Using ex-vivo transduction of oncogenic Kras(G12V into p16/p19(-/- bone marrow cells, we generated transplantable leukemia-initiating cells that rapidly induced tumor formation in the skeletal muscle of immunocompromised NOD.SCID mice. In this model, murine histiocytic sarcomas, equivalent to human myeloid sarcomas, emerged at the injection site 30-50 days after cell implantation and consisted of tightly packed monotypic cells that were CD48+, CD47+ and Mac1+, with low or absent expression of other hematopoietic lineage markers. Tumor cells also infiltrated the bone marrow, spleen and other non-hematopoietic organs of tumor-bearing animals, leading to systemic illness (leukemia within two weeks of tumor detection. P16/p19(-/-; Kras(G12V myeloid sarcomas were multi-clonal, with dominant clones selected during secondary transplantation. The systemic leukemic phenotypes exhibited by histiocytic sarcoma-bearing mice were nearly identical to those of animals in which leukemia was introduced by intravenous transplantation of the same donor cells. Moreover, murine histiocytic sarcoma could be similarly induced by intramuscular injection of MLL-AF9 leukemia cells. This study establishes a novel, transplantable model of murine histiocytic/myeloid sarcoma that recapitulates the natural progression of these malignancies to systemic disease and indicates a cell autonomous leukemogenic mechanism.

Immunohistochemical stains were positive for vimentin and MIC2 (CD99), and the translocation at EWS gene (22q12) was detected. Metastatic workup and a full-body bone scan were negative, confirming primary orbital extraosseous Ewing sarcoma. The patient received neoadjuvant chemotherapy and an orbital exenteration with preservation of eyelids and conjunctiva. He also received adjuvant chemotherapy and local radiotherapy, and he has remained disease-free for almost 3 years.

    The case of a patient with epithelioid sarcoma in the right arm is reported. The diagnosis was delayed because of misinterpretation arising from complexity in the MR findings, including a honeycomb pattern in the subcutaneous fat simulating lymphedema, and an intramuscular diffuse high signal intensity on T2-weighted images without a discrete mass lesion. The histological findings revealed that the diffuse muscular abnormality mainly resulted from denervation of the muscles due to perineural invasion by the tumor, and subcutaneous edema from lymphedema secondary to lymphatic tumor spread concurrent with lymphatic fibrosis. Multiple foci of cortical erosions in the humerus, a rare manifestation of this tumor, were detected 6 months later. (orig.) 11 refs.

    Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare low-grade tumor of modified fibroblasts, with tendency to local recurrence. This unusual entity typically presents as a slow-growing painless mass in the distal extremities of middle-aged subjects. A 48-year-old woman presented to our clinic with a painless subcutaneous mass in the right temporal region. Excisional biopsy made the rare diagnosis of MIFS. Histologic examination showed the unique features that characterize this lesion: a myxoid component with a superimposed inflammatory infiltrate and the presence of distinctive, large, and bizarre Reed-Stemberg-like cells. A second wide tumor bed resection was performed, achieving clear margins. No adjuvant therapy was administered, and the patient is free of disease at 18 months postoperatively. To the best of our knowledge, this is the first reported case of MIFS presenting in the face. This adds another possibility for differential diagnoses of soft tissue tumors of the face.

    Objective The aim of this study was to analyze the imaging features of alveolar soft part sarcoma (ASPS). Methods The imaging features of 11 cases with ASPS were retrospectively analyzed. Results ASPS mainly exhibited an isointense or slightly high signal intensity on T1-weighted imaging (T1WI), and a mixed high signal on T2-weighted imaging (T2WI). ASPS was partial, with rich tortuous flow voids, or “line-like” low signal septa. The essence of the mass was heterogeneous enhancement. The 1H-MRS showed a slight choline peak at 3.2 ppm. Conclusion The wel-circumscribed mass and blood voids, combined with “line-like” low signals play a significant role in diagnosis. The choline peak and the other signs may be auxiliary diagnoses.

    Histiocytic sarcoma (HS) is a neoplasm derived from histiocytes. Its diagnosis was not clear until its immunohistochemistry profile was correctly established. Not much is known about its genetic properties. We report a case of a 48-year-old male patient whose bone marrow was almost completely occupied by monomorphic medium size neoplastic cellularity. Its immunohistochemical profile was CD68+, CD4+, CD45+ with negativity of other dendritic cells, and other lineage markers. Cytogenetic study showed 4 related clones: one with trisomy 8 and extra material on the short arms of chromosome 4; a second line with tetrasomy of chromosome 8, add(4)(p16); the third clone had the same alterations as the previous and deletion of chromosome 3 at q11; the fourth line had tetrasomy 8 and translocation t(3;5)(q25;q35). To our knowledge this is the first HS case showing chromosome 8 trisomy and tetrasomy and the other described alterations. PMID:22937328

    Compared to other bone tumors, bone osteogenic sarcoma (BOS) continues to confer a much grimmer prognosis as the survival benefit of traditional chemotherapy treatment regimens is still unsatisfactory. Chemotherapy was demonstrated to be effective in eradicating both primary tumor and pulmonary metastases in the last century, with effective agents used in various combination regimens having changed the survival rate from less than 10% to 75%. The most common primary bone cancer, BOS is conventionally a primary intramedullary high-grade malignant tumor characterized by malignant cells forming immature bone or osteoid. BOS is a disease with diverse morphological presentations. The treatment of all morphological variants seem to have been the same for over 30 years. The introduction of antiproliferative agents such as insulin growth factor-binding protein 3 hold promise of a potentially veritable therapeutic target. In this review, we highlight recent data on osteosarcoma to consolidate a platform able to connect bench and bedside.

    Management of retroperitoneal soft tissue sarcomas (RP STS) can be very challenging. In contrast to the more common extremity STS, the two predominant histologic subtypes encountered in the retroperitoneum are well-differentiated/dedifferentiated liposarcoma and leiomyosarcoma. Surgery remains the mainstay of treatment for RP STS. Preoperative planning and anticipation of the need for resection of adjacent organs/structures are critical. The extent of surgery, including the role of compartmental resection, is still controversial. Radiation therapy may be an important adjunct to surgery to provide locoregional disease control; this is currently being evaluated in the preoperative setting in the EORTC STRASS trial. Systemic therapy, tailored to the specific histologic subtype, may also be of benefit for the management of RP STS. Further investigation of novel therapies (e.g., targeted therapies, immunotherapy) is needed. Overall, multi-institutional collaboration is important moving forward, to continue to better understand and optimize management of this disease.

    2016-08-01

    Full Text Available Kaposi’s sarcoma-associated herpesvirus (KSHV has an etiologic role in Kaposi’s sarcoma, primary effusion lymphoma and multicentric Castleman’s disease. These diseases are most common in immunocompromised individuals, especially those with AIDS. Similar to all herpesviruses, KSHV infection is lifelong. KSHV infection in tumor cells is primarily latent, with only a small subset of cells undergoing lytic infection. During latency, the KSHV genome persists as a multiple copy, extrachromosomal episome in the nucleus. In order to persist in proliferating tumor cells, the viral genome replicates once per cell cycle and then segregates to daughter cell nuclei. KSHV only expresses several genes during latent infection. Prominent among these genes, is the latency-associated nuclear antigen (LANA. LANA is responsible for KSHV genome persistence and also exerts transcriptional regulatory effects. LANA mediates KSHV DNA replication and in addition, is responsible for segregation of replicated genomes to daughter nuclei. LANA serves as a molecular tether, bridging the viral genome to mitotic chromosomes to ensure that KSHV DNA reaches progeny nuclei. N-terminal LANA attaches to mitotic chromosomes by binding histones H2A/H2B at the surface of the nucleosome. C-terminal LANA binds specific KSHV DNA sequence and also has a role in chromosome attachment. In addition to the essential roles of N- and C-terminal LANA in genome persistence, internal LANA sequence is also critical for efficient episome maintenance. LANA’s role as an essential mediator of virus persistence makes it an attractive target for inhibition in order to prevent or treat KSHV infection and disease.

    Full Text Available In recent years, contingent and survivor workers have emerged as a common reality in business activities. Unfortunately, contingent worker has high job insecurity on his employment status. On the other side, downsizing activities can result in decreasing job security of survivor worker. As a consequence, both contingent and survivor workers very potential have low organizational commitment. However, organizations still have an opportunity to give their workers an exclusive treatment for building organizational commitment without ignoring the fact that workers have other commitment foci.

    Survivors of childhood cancer are at risk for a variety of treatment-related late effects and require lifelong individualized surveillance for early detection of late effects. This study assessed knowledge and perceptions of late effects risk before and after a survivor clinic visit. Young adult survivors (≥ 16 years) and parents of child survivors (survivor program. Sixty-five participants completed a baseline survey and 50 completed both a baseline and follow-up survey. Participants were found to have a low perceived likelihood of developing a late effect of cancer therapy and many incorrect perceptions of risk for individual late effects. Low knowledge before clinic (odds ratio = 9.6; 95% confidence interval, 1.7-92.8; P = .02) and low perceived likelihood of developing a late effect (odds ratio = 18.7; 95% confidence interval, 2.7-242.3; P = .01) were found to predict low knowledge of late effect risk at follow-up. This suggests that perceived likelihood of developing a late effect is an important factor in the individuals' ability to learn about their risk and should be addressed before initiation of education.

    Full Text Available Kaposi’s sarcoma (KS is a multicentric vascular neoplasm associated with the Kaposi’s sarcoma-associated herpes virus (KSHV. KS can occur in immunocompromised patients as well as certain populations in Africa or in the Mediterranean. Less than 5% of KS cases can present with lymphangioma-like kaposi sarcoma (LLKS, which can occur in all KS variants. KS presents with characteristic skin lesions that appear as brown, red, blue, or purple plaques and nodules. The lesions are initially flat and if untreated will become raised. LLKS presents similarly to KS but is associated with severe lymphedema and soft tissue swelling as well as bulla-like vascular lesions. We present the case of an 85-year-old Lebanese, HIV negative, man who presented with a swollen and painful right lower extremity accompanied by necrotic lesions. Wound cultures were positive, and we began the work-up for secondarily infected gangrene. However, skin biopsy results revealed that he in fact had lymphangioma-like Kaposi sarcoma, which allowed us to shift our management. Advanced Kaposi’s sarcoma can present similar to gangrene. It is important to recognize the typical skin lesions of KS and not to overlook Kaposi’s sarcoma or LLKS within the differential.

    Background Myofibroblastic sarcoma was used to be a controversial neoplasm. This study investigated the clinicopathological features of 20 cases of myofibroblastic sarcoma arising in different locations.Methods The paraffin-embedded tissue samples from 20 cases of patients with myofibroblastic sarcoma were stained immunohistochemically, and 5 cases examined by electron microscopy. Student's t test was used to analyze the difference of Ki-67 labeling index between grade 1 and grade 2 myofibroblastic sarcomas.Results Histologically, the tumors were composed of slender spindle cells with eosinophilic cytoplasm, and fusiform,tapering, wavy, or plump ovoid; vesicular nuclei and a small central eosinophilic nucleoli. Immunohistochemically, the tumor cells expressed smooth muscle actin (18/20), muscle specific actin (16/20), fibronectin (20/20) and desmin (2/20).Ultrastructurally, the tumor cells revealed abundant rough endoplasmic reticulum and longitudinally arranged fine filaments with focal densities in the cytoplasm. A clinical follow-up of 19 patients showed that 2 cases experienced local recurrence and distant metastasis 6 months to 4 years after the initial operation. Nine cases recurred locally 17 to 46 months after the initial excision, and 9 cases were alive with no evidence of disease.Conclusions Myofibroblastic sarcomas, which exhibit diverse histological appearance, can easily be misdiagnosed as benign tumors. Myofibroblastic sarcomas are local destructive lesions with frequent recurrence, and may metastase distantly.

    Cancer survival is a stressful experience requiring coping for the maintenance of equilibrium. Lazarus' Theory of Stress and Coping was the framework for this descriptive study of the use and effectiveness of coping strategies as assessed by long-term survivors of cancer. The Jalowiec Coping Scale (JCS) and a subject information sheet (SIS) were mailed to 128 potential subjects, identified by the snowball technique, who survived cancer for > 5 years, were not currently receiving therapy, and were not in a terminal stage of disease. Fifty-nine subjects with a mean survival of 13.03 years correctly completed and returned the questionnaire and were included in data analysis. Respondents were predominantly white (88.1%), female (83.7%), married (72.8%), employed as professionals (57.8%), 41-65 years of age (59.3%), and diagnosed with breast cancer (50.8%). Subjects rated optimistic, supportive, and confrontive strategies as most often used and effective. Length of survival did not result in different choices of strategies. Statistically significant differences were found in coping styles between elderly and middle-aged survivors. Results of this study increase nurses' awareness of effective coping strategies and the importance of assessment of coping in long-term survivors of cancer. The importance of social support, spirituality, and helping others is emphasized.

    The very heterogeneous group of paediatric soft tissue sarcomas account for approximately 7 % of all malignant childhood tumours. More than one half of all cases are rhabdomyosarcomas, some of the over 20 entities are very rare. The prognosis and biology of soft tissue sarcomas in children and adolescents vary greatly depending on histological subtype, the age of the patient, the primary site, the tumour size, tumour invasiveness and the extent of disease at diagnosis. Since 1981, 2918 children and adolescents with soft tissue sarcomas were treated prospectively according to the common treatment protocols of the Cooperative Soft Tissue Sarcoma Study Group (CWS-81 - 96). The known prognostic factors were used to develop a more and more detailed risk stratification. The multimodal treatment includes the use of surgery, chemotherapy and radiotherapy and should be planned by a multidisciplinary team. That way, an overall survival of nearly 70 % over all risk groups could be achieved.

    Although stroke is associated with ageing, a significant proportion of strokes occur in younger people. Younger stroke survivors have experienced care available as inappropriate to their needs. However, insufficient attention has been paid to how the social context shapes their experiences of care. We investigated this question with younger stroke survivors in Greater London, UK. We conducted in-depth interviews with individuals aged between 24 and 62 years. Interviews were analysed thematically, with interpretation informed by Bourdieu's concepts of field, capital and habitus. In the acute care setting it was implicit for participants that expertise and guidance was to be prioritised and largely this was reported as what was received. Individuals' cultural capital shaped expectations to access information, but health care professionals' symbolic capital meant they controlled its provision. After discharge, professional guidance was still looked for, but many felt it was limited or unavailable. It was here that participants' social, cultural and economic capital became more important in experiences of care. The field of stroke shaped younger stroke survivors' experiences of care. Navigating stroke care was contingent on accessing different forms of capital. Differences in access to these resources influenced longer term adjustment after stroke. Stroke care can be conceptualised as a temporal field of social activity and relationships which shapes variations in experiences of care among younger stroke survivors, and differences in expectations of support at different time points after stroke. On entering the field of stroke participants reported needing health care professional guidance and expertise to manage the acute event, yet difficulties accessing information in hospital limited the agency of some individuals wanting to take an active role in their recovery. After discharge from hospital variations in experiences of care among participants were more evident

    Purpose: Peritumoral edema may harbor sarcoma cells. The extent of suspicious edema (SE) included in the treatment volume is subject to clinical judgment, balancing the risk of missing tumor cells with excess toxicity. Our goal was to determine variability in SE delineation by sarcoma radiation oncologists (RO). Methods and Materials: Twelve expert ROs were provided with T1 gadolinium and T2-weighted MR images of 10 patients with high-grade extremity soft-tissue sarcoma. Gross tumor volume, clinical target volume (CTV)3cm (3 cm longitudinal and 1.5 cm radial margin), and CTV2cm (2 cm longitudinal and 1 cm radial margin) were contoured by a single observer. Suspicious peritumoral edema, defined as abnormal signal on T2 images, was independently delineated by all 12 ROs. Contouring agreement was analyzed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: The mean volumes of GTV, CTV2cm, and CTV3cm were, respectively, 130 cm{sup 3} (7-413 cm{sup 3}), 280 cm{sup 3} and 360 cm{sup 3}. The mean consensus volume computed using the STAPLE algorithm at 95% confidence interval was 188 cm{sup 3} (24-565 cm{sup 3}) with a substantial overall agreement corrected for chance (mean kappa = 0.71; range: 0.32-0.87). The minimum, maximum, and mean volume of SE (excluding the GTV) were 4, 182, and 58 cm{sup 3} (representing a median of 29% of the GTV volume). The median volume of SE not included in the CTV2cm and in the CTV3cm was 5 and 0.3 cm{sup 3}, respectively. There were 3 large tumors with >30 cm{sup 3} of SE not included in the CTV3cm volume. Conclusion: Despite the fact that SE would empirically seem to be a more subjective volume, a substantial or near-perfect interobserver agreement was observed in SE delineation in most cases with high-grade soft-tissue sarcomas of the extremity. A median of 97% of the consensus SE is within the CTV2cm (99.8% within the CTV3cm). In a minority of cases, however, significant

  8. Development of A-bomb survivor dosimetry

    Kerr, G.D.

    1995-12-31

    An all important datum in risk assessment is the radiation dose to individual survivors of the bombings in Hiroshima and Nagasaki. The first set of dose estimates for survivors was based on a dosimetry system developed in 1957 by the Oak Ridge National Laboratory (ORNL). These Tentative 1957 Doses (T57D) were later replaced by a more extensive and refined set of Tentative 1965 Doses (T65D). The T65D system of dose estimation for survivors was also developed at ORNL and served as a basis for risk assessment throughout the 1970s. In the late 1970s, it was suggested that there were serious inadequacies with the T65D system, and these inadequacies were the topic of discussion at two symposia held in 1981. In early 1983, joint US- Japan research programs were established to conduct a thorough review of all aspects of the radiation dosimetry for the Hiroshima and Nagasaki A-bomb survivors. A number of important contributions to this review were made by ORNL staff members. The review was completed in 1986 and a new Dosimetry System 1986 (DS86) was adopted for use. This paper discusses the development of the various systems of A-bomb survivor dosimetry, and the status of the current DS86 system as it is being applied in the medical follow-up studies of the A-bomb survivors and their offspring.

Currently, there are no biomarkers that provide reliable prognostic information to guide clinical management or stratify risk among clinical trial participants. The objective of this study was to probe the bronchoalveolar lavage fluid (BALF proteome to identify proteins that differentiate survivors from non-survivors of ARDS. Patients were divided into early-phase (1 to 7 days and late-phase (8 to 35 days groups based on time after initiation of mechanical ventilation for ARDS (Day 1. Isobaric tags for absolute and relative quantitation (iTRAQ with LC MS/MS was performed on pooled BALF enriched for medium and low abundance proteins from early-phase survivors (n = 7, early-phase non-survivors (n = 8, and late-phase survivors (n = 7. Of the 724 proteins identified at a global false discovery rate of 1%, quantitative information was available for 499. In early-phase ARDS, proteins more abundant in survivors mapped to ontologies indicating a coordinated compensatory response to injury and stress. These included coagulation and fibrinolysis; immune system activation; and cation and iron homeostasis. Proteins more abundant in early-phase non-survivors participate in carbohydrate catabolism and collagen synthesis, with no activation of compensatory responses. The compensatory immune activation and ion homeostatic response seen in early-phase survivors transitioned to cell migration and actin filament based processes in late-phase survivors, revealing dynamic changes in the BALF proteome as the lung heals. Early phase proteins differentiating survivors from non-survivors are candidate biomarkers for predicting survival in ARDS.

The injectable applications (vaccines, medications seems to be the reason for that neoplasia, more specifically, the inflammation caused by injury of given drugs or antigens to the health tissue. Generally the FIS presents a more aggressive behavior when compared to sarcoma not associated to application. The most effective treatment has not been established yet, but it is believed that a multimodality of therapies, surgery, radiotherapy, and chemotherapy would be the most indicated option. The knowledge of the illness in all of its aspects will supply to professionals colleges subsidies in relation to the best way to approach its diagnosis and treatment.O sarcoma de aplicação felino (SAF é atualmente um grande desafio para o médico veterinário e também para o proprietário do felino acometido. Aplicações injetáveis por via subcutânea ou intramuscular, como vacinas e medicações, aparecem como iniciadoras do processo de neogênese dessa neoplasia, mais precisamente a inflamação persistente, causada pela lesão ao tecido sadio decorrente do fármaco ou antígeno administrado. Geralmente o SAF apresenta comportamento mais agressivo quando comparado ao sarcoma não associado à aplicação. O tratamento mais eficaz ainda não está estabelecido, mas acredita-se que a multimodalidade de terapias, cirurgia, radioterapia e quimioterapia seja a opção mais indicada.

    Radiation has been associated with increases in noncancerous diseases. An effect of low-dose radiation on the prevalence of clinically detected glaucoma has not been previously reported. We therefore investigated the prevalence of glaucoma in A-bomb survivors and its possible association with radiation dose. A total of 1,589 people who participated in the clinical examination program for A-bomb survivors at the Radiation Effects Research Foundation (RERF) between October 2006 and September 2008 and who had reconstructed radiation doses, were recruited into this cross-sectional screening study. The prevalence of glaucoma and its dose-response relationship to A-bomb radiation were measured. Each subject underwent an initial screening consisting of an interview and ophthalmological examination. Questionable cases with any indication of ocular disease, including glaucoma, were referred to local hospitals for more comprehensive evaluation. A diagnosis of glaucoma was made based on specific optic disc appearance, perimetric results and other ocular findings. Of 1,589 eligible people, we detected 284 (17.9%) cases of glaucoma overall, including 36 (2.3%) cases of primary open-angle glaucoma with intraocular pressure levels greater than 21 mmHg, 226 (14.2%) cases of normal-tension glaucoma and 25 (1.6%) cases of primary angle-closure glaucoma. Seven glaucoma risk factors were examined as potential confounders but only two needed to be included in the final model. Binary regression using a generalized estimating equation method, with adjustment for gender, age, city, cataract surgery or diabetes mellitus, revealed an odds ratio at 1 Gy of 1.31 (95% confidence interval 1.11-1.53, P = 0.001) in the case of normal-tension glaucoma, but no association for other types of glaucoma. The prevalence of normal-tension glaucoma may increase with A-bomb radiation dose, but uncertainties associated with nonparticipation (59% participation) suggest caution in the interpretation of these

    Purpose We described unmet information and service needs of adolescent and young adult (AYA) cancer survivors (15-39 years of age) and identified sociodemographic and health-related factors associated with these unmet needs. Methods We studied 523 AYAs recruited from 7 population-based cancer registries, diagnosed with acute lymphocytic leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, germ cell cancer or sarcoma in 2007-08. Participants completed surveys a median of 11 months from diagnosis. Multivariable logistic regression analyses were used to estimate associations between unmet (information and service) needs and sociodemographic and health-related factors. Results More than half of AYAs had unmet information needs relating to their cancer returning and cancer treatments. AYAs needing services, but not receiving them, ranged from 29% for in-home nursing to 75% for a support group. The majority of AYAs who needed a pain management expert, physical/occupational therapist, mental health worker or financial advice on paying for health care did not receive services. In multivariable analyses, older participants, men, participants of non-White race/ethnicity, and participants who reported less than excellent general health, or fair/poor quality of care were more likely to report unmet information needs. Factors associated with both unmet service and information needs included physical health or emotional problems interfering with social activities or having ≥ 3 physical treatment-related symptoms. Conclusions Recently diagnosed AYA cancer survivors have substantial unmet information needs varying by demographic and health-related factors. Implications for Cancer Survivors We identified subgroups of AYA cancer survivors with high unmet needs that can be targeted for interventions and referrals. PMID:22457219

    Kaposi sarcoma is a low-grade mesenchymal tumor involving blood and lymphatic vessels. There are four variants of this disease, each presenting a different clinical manifestation: classic or sporadic, African or endemic, organ transplant-related or iatrogenic, and AIDS-related or epidemic. Kaposi sarcoma is the most common tumor among patients with HIV infection, occurring predominantly in homosexual or bisexual men. The pulmonary involvement in Kaposi sarcoma occurs commonly in critically immunosupressed patients who commonly have had preceding mucocutaneous or digestive involvement.The etiology of Kaposi sarcoma is not precisely established; genetic, hormonal, and immune factors, as well as infectious agents, have all been implicated. There is evidence from epidemiologic, serologic, and molecular studies that Kaposi sarcoma is associated with human herpes virus type 8 infection. The disease starts as a reactive polyclonal angioproliferative response towards this virus, in which polyclonal cells change to form oligoclonal cell populations that expand and undergo malignant transformation.The diagnosis of pulmonary involvement in Kaposi sarcoma usually can be made by a combination of clinical, radiographic, and laboratory findings, together with the results of bronchoscopy and transbronchial biopsy. Chest high-resolution computed tomography scans commonly reveal peribronchovascular and interlobular septal thickening, bilateral and symmetric ill-defined nodules in a peribronchovascular distribution, fissural nodularity, mediastinal adenopathies, and pleural effusions. Correlation between the high-resolution computed tomography findings and the pathology revealed by histopathological analysis demonstrate that the areas of central peribronchovascular infiltration represent tumor growth involving the bronchovascular bundles, with nodules corresponding to proliferations of neoplastic cells into the pulmonary parenchyma.

    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.

  1. Targeting the p53 Pathway in Ewing Sarcoma

    Directory of Open Access Journals (Sweden)

    Paul M. Neilsen

    2011-01-01

    Full Text Available The p53 tumour suppressor plays a pivotal role in the prevention of oncogenic transformation. Cancers frequently evade the potent antitumour surveillance mechanisms of p53 through mutation of the TP53 gene, with approximately 50% of all human malignancies expressing dysfunctional, mutated p53 proteins. Interestingly, genetic lesions in the TP53 gene are only observed in 10% of Ewing Sarcomas, with the majority of these sarcomas expressing a functional wild-type p53. In addition, the p53 downstream signaling pathways and DNA-damage cell cycle checkpoints remain functionally intact in these sarcomas. This paper summarizes recent insights into the functional capabilities and regulation of p53 in Ewing Sarcoma, with a particular focus on the cross-talk between p53 and the EWS-FLI1 gene rearrangement frequently associated with this disease. The development of several activators of p53 is discussed, with recent evidence demonstrating the potential of small molecule p53 activators as a promising systemic therapeutic approach for the treatment of Ewing Sarcomas with wild-type p53.

    To characterize the radiological and clinicopathologic features of cystic synovial sarcoma. Seven patients with primary cystic synovial sarcoma were evaluated. Computed tomography (CT) and magnetic resonance (MR) imaging were undertaken at the first presentation. The diagnosis of synovial sarcoma was made on the basis of histological examinations followed by molecular analysis. Radiological and clinicopathologic findings were reviewed. CT showed well-defined soft tissue mass without cortical bone erosion and invasion. Calcification was seen at the periphery of the mass in three cases. T2-weighted MR images showed multilocular inhomogeneous intensity mass in all cases, five of which showed fluid-fluid levels. On gross appearance, old and/or fresh hematomas were detected in six cases. In the one remaining case, microscopic hemorrhage in the cystic lumen was proven. Four cases had poorly differentiated areas. In five cases prominent hemangiopericytomatous vasculature was observed. Histologic grade was intermediate in one tumor and high in six. One case had a history of misdiagnosis for tarsal tunnel syndrome, one for lymphadenopathy, two for sciatica and two for hematoma. All cystic synovial sarcomas demonstrated multilocularity with well-circumscribed walls and internal septae. Synovial sarcoma should be taken into consideration in patients with deeply situated multicystic mass with triple signal intensity on T2-weighted MR imaging. (orig.)

    Full Text Available Abstract Background Epithelioid sarcoma is an uncommon high-grade sarcoma, mostly involving the extremities. Case presentation A 33-year-old man was referred to our institute with a diagnosis of Volkmann's contracture with the symptom of flexion contracture of the fingers associated with swelling in his left forearm. Magnetic resonance imaging (MRI showed abnormal signal intensity, comprising iso-signal intensity on T1- and high-signal intensity on T2-weighted images surrounding the flexor tendons in the forearm. Diagnosis of epithelioid sarcoma was made by open biopsy, and amputation at the upper arm was then undertaken. [18F]-2-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET detected multiple lesions with an increased uptake in the right neck, the bilateral upper arms and the right thigh, as well as in the left axillary lymph nodes, with maximum standardized uptake value (SUVmax ranging from 2.0 to 5.5 g/ml. Magnetic resonance imaging confirmed that there was a lesion within the right thigh muscle which was suggestive of metastasis, even though the lesion was occult clinically. Conclusion Increased uptake on FDG-PET might be representative of epithelioid sarcoma, and for this reason FDG-PET may be useful for detecting metastasis. Muscle metastasis is not well documented in epithelioid sarcoma. Accordingly, the frequency of muscle metastasis, including occult metastasis, needs to be further analyzed.

    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.

    Uterine sarcomas are a group of rare tumours that provide considerable challenges in their treatment. Radiological diagnosis prior to hysterectomy is difficult, with the diagnosis frequently made post-operatively. Current staging systems have been unsatisfactory, although a new FIGO staging system specifically for uterine sarcomas has now been introduced, and may allow better grouping of patients according to expected prognosis. While the mainstay of treatment of early disease is a total abdominal hysterectomy, it is less clear whether routine oophorectomy or lymphadenectomy is necessary. Adjuvant pelvic radiotherapy may improve local tumour control in high risk patients, but is not associated with an overall survival benefit. Similarly there is no good evidence for the routine use of adjuvant chemotherapy. For advanced leiomyosarcoma, newer chemotherapy agents including gemcitabine and docetaxel, and trabectedin, offer some promise, while hormonal therapies appear to be more useful in endometrial stromal sarcoma. Novel targeted agents are now being introduced for sarcomas, and uterine sarcomas, and show some indications of activity. Non-pharmacological treatments, including surgical metastatectomy, radiofrequency ablation, and CyberKnife radiotherapy, are important additions to systemic therapy for advanced metastatic disease.

    Full Text Available Synovial sarcoma is the fourth most common type of sarcoma. It represents between 5% -10% of all soft tissue sarcomas and most prevalent in aged between 15 - 40 years. Synovial sarcoma is the most commonly misdiagnosed soft tissue malignancy, initially as an inflammation process,often because it may be slow-growing, have a benign appearance on imaging studies, may vary in size, and may have pain similar to that associated with trauma.    A rare case is presented of 17 years old women with a synovial sarcoma biphasic. The primary tumor originated in the left elbow since 2004. Since then, the patient has had repeated passive or active left elbow pain and tenderness. No history of trauma. She has not developed metastases of the lung. The patient refused to have surgery and others medical procedures that already planned and explained to her. The conclusion of this case report point that radiology is important to diagnosis and planning for further management

    2011-01-01

    Full Text Available Myxoid soft-tissue sarcomas represent a heterogeneous group of mesenchymal tumors characterized by a predominantly myxoid matrix, including myxoid liposarcoma (MLS, low-grade fibromyxoid sarcoma (LGFMS, extraskeletal myxoid chondrosarcoma (EMC, myxofibrosarcoma, myxoinflammatory fibroblastic sarcoma (MIFS, and myxoid dermatofibrosarcoma protuberans (DFSP. Cytogenetic and molecular genetic analyses have shown that many of these sarcomas are characterized by recurrent chromosomal translocations resulting in highly specific fusion genes (e.g., FUS-DDIT3 in MLS, FUS-CREB3L2 in LGFMS, EWSR1-NR4A3 in EMC, and COL1A1-PDGFB in myxoid DFSP. Moreover, recent molecular analysis has demonstrated a translocation t(1; 10(p22; q24 resulting in transcriptional upregulation of FGF8 and NPM3 in MIFS. Most recently, the presence of TGFBR3 and MGEA5 rearrangements has been identified in a subset of MIFS. These genetic alterations can be utilized as an adjunct in diagnostically challenging cases. In contrast, most myxofibrosarcomas have complex karyotypes lacking specific genetic alterations. This paper focuses on the cytogenetic and molecular genetic findings of myxoid soft-tissue sarcomas as well as their clinicopathological characteristics.

    Full Text Available Ewing’s sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing’s sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis. Computed tomography (CT imaging showed a mass in the left posterior fossa compressing the brainstem. The patient then underwent surgical excision followed by adjuvant chemoradiation therapy. Two years later, the patient presented with severe lower back pain and urinary incontinence. Whole-spine magnetic resonance imaging (MRI showed cerebrospinal fluid (CSF seeding from the L5 to the S4 vertebrae. Primary cranial Ewing’s sarcoma is considered in the differential diagnosis of children with extra-axial posterior fossa mass associated with destructive permeative bone lesions. Although primary cranial Ewing’s sarcoma typically has good prognosis, our patient developed metastasis in the lower spine. Therefore, with CNS Ewing’s sarcoma, screening of the entire neural axis should be taken into consideration for early detection of CSF seeding metastasis in order to decrease the associated morbidity and mortality.

    Though about 20% of working age breast cancer survivors do not return to work after treatment, few studies have addressed risk factors for unemployment. The majority of studies on occupational consequences of breast cancer focus on non-employment, which is a mixture of sickness absence, unemployment, retirement pensions and other reasons for not working. Unemployment in combination with breast cancer may represent a particular challenge for these women. The aim of the present study is therefore to analyze the risk for unemployment in the years following diagnosis and treatment for breast cancer. This study included 14,750 women diagnosed with breast cancer in Denmark 2001-2009 identified through a population-based clinical database and linked with information from Danish administrative population based registers for information on labour market affiliation, socio-demography and co-morbid conditions. Multivariable analyses were performed by Cox's proportional hazard models. Two years after treatment, 81% of patients were still part of the work force, 10% of which were unemployed. Increasing duration of unemployment before breast cancer was associated with an adjusted HR = 4.37 (95% CI: 3.90-4.90) for unemployment after breast cancer. Other risk factors for unemployment included low socioeconomic status and demography, while adjuvant therapy did not increase the risk of unemployment. Duration of unemployment before breast cancer was the most important determinant of unemployment after breast cancer treatment. This allows identification of a particularly vulnerable group of patients in need of rehabilitation.

    To evaluate the degree of psychological distress in adult childhood cancer survivors in Switzerland and to characterize survivors with significant distress. Childhood cancer survivors who were age younger than 16 years when diagnosed between 1976 and 2003, had survived more than 5 years, and were currently age 20 years or older received a postal questionnaire. Psychological distress was assessed using the Brief Symptom Inventory (BSI). Raw scores were transformed into T scores according to the German norm sample, and the proportion of participants being at increased risk for psychological distress was calculated (case rule: T > or = 63). t tests and univariable and multivariable logistic regressions were used for statistical analyses. One thousand seventy-six survivors (63.% of eligible survivors, 71.9% of contacted survivors) returned the questionnaire, 987 with complete data on BSI. Comparison with the norm populations showed lower T scores (T < 50) in the Global Severity Index (GSI; T = 46.2), somatization (T = 47.6), obsessive-compulsive tendencies (T = 46.9), and anxiety (T = 48.4). However, more childhood cancer survivors (especially women) had increased distress for GSI (14.4%), interpersonal sensitivity (16.5%), depression (13.4%), aggression (16.9%), and psychotic tendencies (15.6%) than the expected 10% from the norm population. Caseness was associated with female sex, being a single child, older age at study, and self-reported late effects, especially psychological problems. Results show that childhood cancer survivors, on average, have less psychological distress than a norm population but that the proportion of survivors at risk for high psychological distress is disproportionally large. Monitoring psychological distress in childhood cancer survivors may be desirable during routine follow-up, and psychological support should be offered as needed.

    Retroperitoneal soft tissue sarcomas (RPS) are uncommon tumors. The diagnosis is frequently made later in the evolution of the disease due to the absence of specific symptomatology. Surgery with total resection of the tumor is the treatment of choice, but is only possible in 38 to 75% of cases. Six cases of RPS have been retrospectively reviewed; the mean time to diagnosis was 5 months; diagnosis was established via CT scan, which determined the retroperitoneal tumor location and its relationship to the neighboring organs. The most common symptoms were the presence of an abdominal mass and accompanying abdominal pain; signs of urinary and vascular compression were not found until later. Surgery with total resection was performed in 4 cases, and with partial resection in 2 cases. The histological findings were as follows: 3 liposarcomas, 2 rhabdomyosarcomas, and 1 fibrosarcoma. Tumor recurrence developed in 2 cases (liposarcomas), necessitating further surgery and complete resection. Two patients were lost to follow-up. RPS are characterized by locoregional relapse and metastases. Disease outcome depends on the histological type, tumor grade, and on the possibility of carrying out complete resection.

    Full Text Available Myeloid Sarcoma may occur in patients with an acute or chronic myeloproliferative disorder as well as de novo, with no apparent sign or symptom of concomitant haematological disease. The patients are preferentially young male and the site of disease localization may vary from central nervous system to pleura and thorax, with a common involvement of the reticuloendothelial system. The disease often shows chromosomal rearrangements, involving chromosomes 7, 8 and 3 and sometimes a complex karyotype (more than 3 abnormalities is detected at diagnosis. The prognosis of this disease is dismal and only high-dose chemotherapy with autologous or allogeneic stem cells transplantation (auto or allo-SCT may be potentially curative. In the absence of definitive elements that can define the prognosis of extra-medullary localization of “standard risk” AML, Clinicians should pursue the collection of data from different Centres and design of homogeneous treatment strategies, that could integrate standard chemotherapy with specific approaches, such as radiotherapy, transplant procedures or, in selected cases (such as those displaying molecular abnormalities involving protein tyrosine-kinases, molecularly targeted therapies.

    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.

    All the pertinent radiographs of 83 patients with histologically proven Ewing's sarcoma were reviewed. Forty-nine patients were in the pediatric age group, and 34 were adults. The mean age, the symptoms and time from symptoms to diagnosis were evaluated in the 2 groups. The site of primary involvement was in 54% the long bones, 35% the flat bones, 8% the small bones and 3% extraosseous. For the primary site we considered the diagnostic results of the standard radiographic investigations and in some cases the usefulness of angiography, xeroradiography and telethermography. At presentation we also evaluated the possible diffusion of the disease with standard radiographic surveys (chest and skeletal, including limbs) and with foot lymphography in selected cases. In this way, 57 patients (69%) were considered to have localized disease. In this group, we also considered the value of the periodic radiographic follow-up, which enabled us to disclose the appearance of metastases (chest 64%, bone 54%, lymph nodes 11%) in 28 cases (49%). Finally, we made a comparison of the different radiologic and epidemiologic findings between children and adults.

    Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specific enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES.

  18. Dimensions and correlates of negative attitudes toward female survivors of sexual violence in Eastern DRC.

    2014-06-01

    The aim of the study described in this article is to examine the dimensions and correlates of attitudes toward survivors of sexual violence (SV) in Eastern Democratic Republic of the Congo (DRC). Four dimensions of attitudes were identified: victim responsibility, victim denigration, victim credibility, and deservingness. Gender roles attitudes represented the most significant correlate of attitudes toward survivors in this population. Other significant correlates of overall attitudes toward survivors included current employment, province of residence, knowledge about the SV law, awareness about where to go for information on sexual and gender-based violence (SGBV), and the perceived prevalence of SV in own community. There are differences and communalities in the variables associated with the various dimensions of attitudes. For example, sex of the respondent and discussion of SGBV with others were only significantly associated with the tendency to ascribe responsibility to the victim. The findings indicate that changing negative gender norms should be central to efforts aimed at promoting accepting attitudes toward survivors. Furthermore, addressing the various dimensions of attitudes toward survivors may require different strategies.

    It is important that teenage and young adult (TYA) cancer survivors adopt a healthy lifestyle, since health vulnerabilities associated with their diagnosis and treatment may be exacerbated by poor health behaviors. This review aims to synthesize the current literature on health behavior change interventions created specifically for TYA-aged cancer survivors. MEDLINE, EMBASE, PsycINFO, and CINAHL databases were searched for studies investigating interventions targeting one or more health behaviors, including: physical activity, diet, smoking cessation, and alcohol consumption. Studies were eligible for review if the study population were defined as TYA cancer survivors and the mean age of the sample was younger than 30 years of age. Twelve studies were identified, of which nine were randomized controlled trials. Physical activity was the most commonly targeted health behavior. Six of the 12 interventions included within this review were successful in changing health behavior. Due to the heterogeneity of intervention characteristics, the relationship between intervention efficacy or outcome and intervention content, delivery mode, or theoretical framework was not discernible. Nevertheless, trends emerged relating to the delivery and content of health behavior interventions designed specifically for TYA cancer survivors. More research is required to identify the most effective means of promoting health behavior change among the TYA cancer survivor population. Specifically, future research should focus on providing evidence of the efficiency and feasibility of interventions that use online technologies to facilitate remote intervention delivery and peer support.

    The medical examination of A-bomb survivors was carried out in Brazil, Argentina, Bolivia, Republic of Peru, and Paraguay from October 25th to November 11th 1994. The survivors were 191 persons, and 98 (51.3%) of them received health consultation. Sixty-two persons were exposured in Hiroshima and 36 in Nagasaki. Average age of the medical examinee was 65.0{+-}8.5-year-old. The holding rate of A-bomb survivor`s handbook was 55.1%. The lowered physical vitality and the involution of the mental vitality with increased age were observed from interview sheets. This first orthopedic examination revealed abnormal findings in 12 persons. Sixty-five persons required further examinations. Cardiovascular risk factors of such as hypertension, obesity, hyperlipidemia and diabetes mellitus were observed. (H.O.).

    Impaired attention is well recognized in childhood cancer survivors. We prospectively evaluated 162 long-term survivors of childhood acute lymphoblastic leukemia to study an association between presence of neurologic soft signs as measured by Zurich Neuromotor Scale, bedside evaluation of anti-saccades, and attention deficit disorder. Attention deficit disorder was recognized in 10.5% of the study cohort. We did not find an association of attention deficit with presence of any soft sign. However, there was an association between presence of abnormal anti-saccades and attention deficit (P = .04). These results will require further validation and if confirmed may introduce a quick bedside method of assessing impaired attention in cancer survivors.

    Objective: To study the clinical characteristics and radiological features of synovial sarcoma in childhood and its relation to the diagnosis and treatment. Methods:The clinical radiological features of 15 children with synovial sarcoma proved surgically and pathologically were analyzed. Results: In children, the tumor boundaries are poorly defined due to paucity of fat, and metastasis usually occurs early. Eight patients in this series had bone involvement, including: direct erosion by tumor causing cortical destruction, indirect pressure defect with sharp margin and reactive bone sclerosis and bone destruction of the primary intraosseous synovial sarcoma.Conclusion: The tumor is often misdiagnosed, the final confirmed diagnosis must be made by histological examination with imaging findings. It is emphasized that the patients should be treated with radiotherapy and chemotherapy preoperatively and postoperatively.

    Complications from lost gallstones after cholecystectomy are rare but varied from simple perihepatic abscess to empyema and expectoration of gallstones. Gallstone complications have been reported in nearly every organ system, although reports of malignant masquerade of retained gallstones are few. We present the case of an 87-year-old woman with a flank soft tissue tumor 4 years after laparoscopic cholecystectomy. The initial clinical, radiographic and biopsy findings were consistent with soft tissue sarcoma (STS), but careful review of her case in multidisciplinary conference raised the suspicion for retained gallstones rather than STS. The patient was treated with incisional biopsy/drainage of the mass, and gallstones were retrieved. The patient recovered completely without an extensive resectional procedure, emphasizing the importance of multidisciplinary sarcoma care to optimize outcomes for potential sarcoma patients.

    Full Text Available Primary lung sarcoma is an extremely rare tumor, accounting for less than 0.5% of all lung tumors. Histological subtypes are differentiated on the basis of immunohistochemical markers, such as vimentin, desmin, actin, CD99, and epithelial membrane antigen. A 50-year-old male presented with progressively increasing shortness of breath with cough for 2 months. On Contrast Enhanced Computed Tomography (CECT of thorax a large heterogeneous mass with multiple areas of necrosis, occupying almost whole of left hemithorax was seen. CT-guided Fine Needle Aspiration Cytology (FNAC revealed spindle cell neoplasm. Histopathological examination revealed a spindle cell sarcoma. On immunohistochemistry the tumor cells expressed both epithelial membrane antigen and vimentin. Hence, final impression from immunohistochemistry was primary monophasic synovial sarcoma of lung.

    Synovial sarcoma metastasis affecting the heart and infiltrating the mitral valve is a very rare pathology. We report the case of a 44-year-old male treated with chemotherapy for atypical synovial sarcoma of the oral mucosa who presented to our clinic after cardiac decompensation with a presumptive diagnosis of myxoma of the left atrium. A large necrotic tumour positive for CK 22, EMA, CD 99 and BCL-2 but negative for translocation in COBRA-FISH analysis by break-apart probe could be excised and revealed a very rare subtype of synovial sarcoma metastasis arising from the endocard of the left atrium. The tumour was resected and the mitral valve reconstructed through ring annuloplasty. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Full Text Available Ewing sarcoma of bone is classically a permeative lesion in the diaphysis of long bones in children. While they occur primarily in children and adolescents, they can be seen in young adults in their 20s, but these are typically seen in flat bones. The permeative nature of the lesion can elicit new bone formation creating a partially sclerotic appearance, cortical expansion presenting as a “Codman triangle,” or have an “onion-skin” type of aggressive periosteal reaction/periostitis. Ewing sarcoma is rarely seen without an associated soft-tissue mass and is even rarer to just have benign-appearing periostitis (e.g., thick, uniform, or wavy cortex. We present such a case of Ewing sarcoma in a young adult confined to just the medullary metadiaphysis without cortical erosion or soft-tissue mass. To the best of our knowledge, this is the first case to be reported in the radiology literature.

    Full Text Available Before the AIDS epidemic, Kaposi's sarcoma was found mainly in elderly men of Mediterranean coast, eastern European background and Jewish ancestry (rarely in older women and is a slow growing skin tumor. In AIDS patients, the KS tends to develop more rapidly compromising the skin, lungs, gastrointestinal tract and other organs. In people with AIDS, Kaposi's sarcoma is caused by an interaction between HIV, a weakened immune system and human herpes virus 8. It affects approximately 20% of people with HIV that don’t take antiretroviral drugs. It is more common in homosexual’s patients, but may appear in any HIV positive individual, in Africa where heterosexual HIV transmission route is the most important can also be found in children and women. We are presenting a case of Kaposi sarcoma in a young female admitted at the Internal Medicine Department of Dora Nginza Hospital.

    2017-01-01

    Intensive clinical research in the sarcoma field has provided insight into the histopathological diversity of soft tissue sarcomas (STS) and led to the introduction of many new agents that promise to play an important role in the management of patients with STS. While an increasing body of scientific data has advanced our knowledge of this complex family of mesenchymal diseases, several controversies remain to be resolved: Is doxorubicin-based therapy still the definitive standard first-line treatment for all patients with unresectable and/or metastatic STS of all subtypes? Is histology-driven therapy beyond gastrointestinal stromal tumors a reality or are we pursuing an unachievable objective? Are we making practical headway in the establishment of sarcoma reference centers? Is it clearly established which is the best parameter to evaluate the efficacy of a new agent in STS?

    2015-08-01

    Full Text Available Epithelioid sarcoma is a soft tissue sarcoma of children and young adults for which the preferred treatment for localised disease is wide surgical resection. Medical management is to a great extent undefined, and therefore for patients with regional and distal metastases, the development of targeted therapies is greatly desired. In this review we will summarize clinically-relevant biomarkers (e.g., SMARCB1, CA125, dysadherin and others with respect to targeted therapeutic opportunities. We will also examine the role of EGFR, mTOR and polykinase inhibitors (e.g., sunitinib in the management of local and disseminated disease. Towards building a consortium of pharmaceutical, academic and non-profit collaborators, we will discuss the state of resources for investigating epithelioid sarcoma with respect to cell line resources, tissue banks, and registries so that a roadmap can be developed towards effective biology-driven therapies.

    The epidemic form of Kaposi's sarcoma is the most frequent tumor in sieropositive patients. Every part of the body including oral cavity is affected by these lesions. According to modern acknowledgement in treating oropharynge carcinoma, radiotherapy is used for management of oral Kaposi's sarcoma. This paper reports a study of 10 patients suffering from Kaposi's sarcoma correlated to AIDS (EKS) treated with radiotherapy and chemiotherapy, achieving good results, at the Istituto Nazionale per lo Studio e la Cura dei Tumori of Milan (Divisone di Radioterapia C) from 1988 to 1992. Treatment has been performed using linear accelerator (6 Mev) or Co 60 unity in order to reach the deepest layer of mucosa lesions. Radiotherapy schedule consisted of 150-200 cGy daily fractions given 5 times/week (w) for 4-5 w in split-course.

    Transarticular spread of tumor is rare; it has only been reported in the sacroiliac joint, intervertebral disk spaces, and facet joints. The anatomic and kinetic characteristics of the sacroiliac joint, as well as the changes the joint undergoes during a lifetime, make it particularly vulnerable to transarticular tumor invasion. Although extremely rare, Ewing sarcoma can extend through the sacroiliac joint and be virtually indistinguishable radiologically from septic arthritis. Furthermore, the clinical presentation of a child with Ewing sarcoma can be similar to that of a child with osteomyelitis. Laboratory values are quite nonspecific and are not always helpful in differentiating between the entities. Therefore, the possibility of sacroiliac joint transarticular Ewing sarcoma should be considered in a child presenting with hip pain, despite clinical, radiological and laboratory findings suggesting an infectious process.

    The purpose of the study was to explore the experience of atomic bomb survivors from Hiroshima and Nagasaki. Never has the world experienced such extreme devastation as with the atomic bombings of Hiroshima and Nagasaki, Japan, in August 1945. Although significant quantitative research has been completed about the medical effects following radiation, the literature lacks qualitative exploration from a holistic health perspective. This was a qualitative descriptive study, using methods of narrative analysis, oral history and ethnography. The sample for this research included eight individuals who were exposed to the atomic bombings in Japan and currently reside in the United States. Findings provide insight to the resilience that the survivors exhibited immediately following the bomb, as well as throughout the 65 years following the event. From ethnographic data and interviews with survivors, a thematic structure was developed that depicts the essential elements of the atomic bomb experience. Two ways of being in the world followed the bombing: surviving and thriving, with resilience serving as a lever, allowing for fluid movement over time across the continuum. Individuals experiencing surviving exhibited anxiety about their personal and family members' health, expressed mistrust, and felt a stigma associated with being a survivor. For those who were thriving, peace activism, overcoming and forgiveness were typically displayed. Findings from this study add to the disaster nursing literature and highlight the role resilience plays in the atomic bomb survivors' life perspective. © 2011 The Author.

    2003-01-01

    OBJECTIVE To identify characteristics that facilitate trust in the patient-provider relationship among survivors of intimate partner violence (IPV). DESIGN Semistructured, open-ended interviews were conducted to elicit participants' beliefs and attitudes about trust in interactions with health care providers. Using grounded theory methods, the transcripts were analyzed for common themes. A community advisory group, composed of advocates, counselors and IPV survivors, helped interpret themes and interview exerpts. Together, key components of trust were identified. SETTING Eastern Massachusetts. PARTICIPANTS Twenty-seven female survivors of IPV recruited from community-based IPV organizations. MAIN RESULTS Participants' ages ranged from 18 to 56 years, 36% were African American, 32% Hispanic, and 18% white. We identified 5 dimensions of provider behavior that were uniquely important to the development of trust for these IPV survivors: 1) communication about abuse: provider was willing to openly discuss abuse; 2) professional competency: provider asked about abuse when appropriate and was familiar with medical and social histories; 3) practice style: provider was consistently accessible, respected confidentiality, and shared decision making; 4) caring: provider demonstrated personal concern beyond biomedical role through nonjudgmental and compassionate gestures, empowering statements, and persistent, committed behaviors; 5) emotional equality: provider shared personal information and feelings and was perceived by the participant as a friend. CONCLUSIONS These IPV survivors identified dimensions of provider behavior that facilitate trust in their clinical relationship. Strengthening these provider behaviors may increase trust with patients and thus improve disclosure of and referral for IPV. PMID:12911643

    The purpose of this study was to identify aftercare services for domestic minor of sex trafficking (DMST) survivors provided by U.S. residential treatment centers. A qualitative research study was conducted with aftercare program personnel from five U.S. residential treatment centers for DMST survivors. Interviews were conducted with staff from five different residential treatment centers providing services exclusively to domestic minor sex trafficking survivors. Participants described the range of services offered to address survivors' posttrafficking needs. Participants' responses assisted in expanding an existing care model to include education re-entry, family reunification, family reconciliation, and emergency substance use services. This study led to the refinement of an aftercare service delivery model and laid the foundation to develop best practice guidelines for providing aftercare services to DMST survivors. Sex trafficking is a global health problem affecting our youth today. Nurses have a vital role in combatting sex trafficking by raising awareness about the problem and restoring the lives of sex trafficking victims by implementing innovative care programs. © 2017 Sigma Theta Tau International.

    Breast cancer is defined as a chronic disease.Increasing amounts of attention have been paid to the health management of breast cancer survivors. An important issue is how to find the most appropriate method of follow-up in order to detect long-term complications of treatment, local recurrence and distant metastasis and to administer appropriate treatment to the survivors with recurrence in a timely fashion. Different oncology organizations have published guidelines for following up breast cancer survivors. However, there are few articles on this issue in China. Using the published follow-up guidelines,we analyzed their main limitations and discussed the content,follow-up interval and economic benefits of following up breast cancer survivors in an effort to provide suggestions to physicians.Based on a large number of clinical trials, we discussed the role of physical examination, mammography, liver echograph, chest radiography, bone scan and so on. We evaluated the effects of the above factors on detection of distant disease, survival time,improvement in quality of life and time to diagnosis of recurrence.The results of follow-up carried out by oncologists and primary health care physicians were compared. We also analyzed the correlation factors for the cost of such follow-up. It appears that follow-up for breast cancer survivors can be carried out effectively by trained primary health care physicians. If anything unusual arises, the patients should be transferred to specialists.

    Full Text Available Background. Kaposi’s sarcoma (KS in transplant recipients is about 400 to 500 times rate in the general population. It is strongly associated to Human herpesvirus-8 (HHV-8 infection which has been found in 95% of KS lesions. The optimal approach to managing posttransplantation KS is to reduce or discontinue immunosuppressive therapy but this strategy carries a risk of the acute rejection of the graft. Recently, the use of an mTOR inhibitor has added new opportunities for KS treatment and prevention. Case Report. We report a case of 24 years-old Turkish woman with visceral HHV-8-associated Kaposi's sarcoma after orthotopic liver transplantation. Conclusion. Posttransplantation KS is considered an experimental model of virus induced tumor suggesting the usefulness of HHV-8 screening in transplant recipient and donor. Therapeutic approaches are complex and require a multidisciplinary team.

    Undifferentiated sarcomas are rare tumors not classified into any sarcoma subtype. Due to their rarity, imaging findings of undifferentiated sarcomas are poorly characterized. The purpose of this report was to present imaging findings of a pathologically confirmed undifferentiated sarcoma originated from the left kidney of a 12-year-old boy. The mass was infiltrative involving the renal pelvis. It mimicked massive hilar lymphadenopathy with a preserved renal contour visible by both ultrasonography and CT. Renal vein thrombosis was also observed. Although undifferentiated sarcomas are rare, they should be considered in differential diagnosis of infiltrative renal masses with renal pelvis invasion in children.

    Kaposi's sarcoma is a multifocal proliferative vascular tumor involving the skin and other organ and psoriasis is a chronic cutaneous disease with papules and plaques with white scale. Development of Kaposi's sarcoma in psoriasis patients has been reported rarely. A 71-year-old man presented with multiple brownish to violaceous plaques on both feet and arms which were found 4 months ago. The biopsy confirmed Kaposi's sarcoma. The patient was diagnosed with psoriasis vulgaris 10 years ago and Kaposi's sarcoma lesions developed between psoriatic plaques. We herein report a rare case of simultaneous occurrence of Kaposi's sarcoma and psoriasis vulgaris which need quite different treatment. PMID:27904275

    Full Text Available Abstract Background Synovial sarcoma is a high-grade malignant tumor of soft tissue, characterized by the specific chromosomal translocation t(X;18, and its resultant SYT-SSX fusion gene. Despite intensive multimodality therapy, the majority of metastatic or relapsed diseases still remain incurable, thus suggesting a need for new therapeutic options. We previously demonstrated the antigenicity of SYT-SSX gene-derived peptides by in vitro analyses. The present study was designed to evaluate in vivo immunological property of a SYT-SSX junction peptide in selected patients with synovial sarcoma. Methods A 9-mer peptide (SYT-SSX B: GYDQIMPKK spanning the SYT-SSX fusion region was synthesized. Eligible patients were those (i who have histologically and genetically confirmed, unresectable synovial sarcoma (SYT-SSX1 or SYT-SSX2 positive, (ii HLA-A*2402 positive, (iii between 20 and 70 years old, (iv ECOG performance status between 0 and 3, and (v who gave informed consent. Vaccinations with SYT-SSX B peptide (0.1 mg or 1.0 mg were given subcutaneously six times at 14-day intervals. These patients were evaluated for DTH skin test, adverse events, tumor size, tetramer staining, and peptide-specific CTL induction. Results A total of 16 vaccinations were carried out in six patients. The results were (i no serious adverse effects or DTH reactions, (ii suppression of tumor progression in one patient, (iii increases in the frequency of peptide-specific CTLs in three patients and a decrease in one patient, and (iv successful induction of peptide-specific CTLs from four patients. Conclusions Our findings indicate the safety of the SYT-SSX junction peptide in the use of vaccination and also give support to the property of the peptide to evoke in vivo immunological responses. Modification of both the peptide itself and the related protocol is required to further improve the therapeutic efficacy.

  2. The clinical use of biomarkers as prognostic factors in Ewing sarcoma

    Full Text Available Abstract Ewing Sarcoma is the second most common primary bone sarcoma with 900 new diagnoses per year in Europe (EU27. It has a poor survival rate in the face of metastatic disease, with no more than 10% survival of the 35% who develop recurrence. Despite the remaining majority having localised disease, approximately 30% still relapse and die despite salvage therapies. Prognostic factors may identify patients at higher risk that might require differential therapeutic interventions. Aside from phenotypic features, quantitative biomarkers based on biological measurements may help identify tumours that are more aggressive. We audited the research which has been done to identify prognostic biomarkers for Ewing sarcoma in the past 15 years. We identified 86 articles were identified using defined search criteria. A total of 11,625 patients were reported, although this number reflects reanalysis of several cohorts. For phenotypic markers, independent reports suggest that tumour size > 8 cm and the presence of metastasis appeared strong predictors of negative outcome. Good histological response (necrosis > 90% after treatment appeared a significant predictor for a positive outcome. However, data proposing biological biomarkers for practical clinical use remain un-validated with only one secondary report published. Our recommendation is that we can stratify patients according to their stage and using the phenotypic features of metastases, tumour size and histological response. For biological biomarkers, we suggest a number of validating studies including markers for 9p21 locus, heat shock proteins, telomerase related markers, interleukins, tumour necrosis factors, VEGF pathway, lymphocyte count, and a number of other markers including Ki-67.

    A 12-year-old mixed breed dog was presented for evaluation of progressive paraparesis and ataxia. Magnetic resonance (MR) imaging was performed and identified multifocal intradural spinal cord mass lesions. The lesions were hyperintense in T2-weighted sequences, isointense to mildly hyperintense in T1-weighted sequences with strong contrast enhancement of the intradural lesions and spinal cord meninges. Spinal cord neoplasia was suspected. A diagnosis of intramedullary spinal cord histiocytic sarcoma, confined to the central nervous system, was confirmed histopathologically. Spinal cord histiocytic sarcoma is a rare neoplasm, but should be included in the differential diagnosis for dogs with clinical signs of myelopathy.

    Follicular dendritic cell sarcoma is a rare neoplasm that originates from follicular dendritic cells in lymphoid follicles. This disease usually involves the lymph nodes, and especially the head and neck area. Rarely, extranodal sites may be affected, including tonsil, the oral cavity, liver, spleen and the gastrointestinal tract. We report here on the imaging findings of follicular dendritic cell sarcoma of the abdomen that involved the retroperitoneal lymph nodes and colon. It shows as a well-defined, enhancing homogenous mass with internal necrosis and regional lymphadenopathy.

    Full Text Available Clear cell sarcoma (CCS is a recently described variant of sarcoma characterized by prominent clear cells showing features similar to clear cell melanoma. This neoplasm was first described by Dr. Franz M. Erzinger. Primary CCS usually arises in deeper soft tissues, in association with fascia, tendons, or aponeuroses. Characteristic translocation t(12;22 (q13;q12 has been considered pathognomonic for CCS. Prognosis is related to tumor size. An early recognition and initial radical surgery is the key to a favourable outcome. We present a patient with an unusual neoplasm that resembled malignant melanoma.

    Results of treatment of 101 cases of soft tissue sarcoma are presented in the paper. Preoperative irradiation technique and radical program of treatment are described. Combined radiation and surgical treatment was given to 45 patients whereas conservative--to 56. Sixty-three cases received adjuvant combination chemotherapy. Response and three-year survival rates were compared to those in control group treated by photons. The results observed in patients of combined and conservative treatment groups who had been irradiated with fast neutrons proved significantly better than in controls. These data suggest vistas in application of fast neutron irradiation for the treatment of soft tissue sarcomas.

    Kaposi's sarcoma-associated herpesvirus (KSHV) is the primary etiological agent of Kaposi's sarcoma, primary effusion lymphoma and muticentric Castleman's disease. In common with the other herpesviruses, KSHV exhibits both latent and lytic life cycles, both of which are characterized by distinct gene expression profiles and programs. KSHV encodes proteins which play essential roles in the inhibition of host adaptive and innate immunity, the inhibition of apoptosis, and the regulation of the cell cycle. KSHV also encodes several proteins which have transforming and intrcellular signalling activity.

    2016-03-01

    Full Text Available This aim of this interpretive case study was to understand meanings of the experience of illness from the perspective of eight survivors of stroke. Data were collected by means of semi-structured interviews and qualitative thematic analysis. The experience of stroke generated negative feelings such as fear of death, disability, loss of autonomy and inability to work. Social support of family and religion was essential to cope with the changes in everyday life and inefficiency of the health care network experienced by the participants. Lack of guidance was identified, especially from nurses, for home care of patients. The results of the study suggest the need to strengthen health education on predictive symptoms of stroke, awareness of the impacts of this disease on the life of survivors, and the need for multidisciplinary health care teams to encourage proactivity of survivors' family members.

    Full Text Available Tumors arising from the soft tissues are uncommon in children, accounting for about 6% of all childhood malignancies. 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 Bone sarcomas are rare tumors, approximating 0.2% of all cancers, with osteosarcoma (OGS, chondrosarcoma, and Ewing sarcoma being the most common cancers in this subset. The formation of disease management groups/clinics focused on sarcomas has resulted in better understanding and management of these uncommon tumors. Multiple large-scale retrospective data from Tata Memorial Hospital (TMH and All India Institute of Medical Sciences have reported outcomes comparable to Western data in the field of OGS and Ewing sarcoma, with interesting prognostic factors identified for further evaluation. Soft tissue sarcomas are a rare heterogeneous group of tumors, more than 50 different tumor entities. The common subtypes identified in India include Ewing sarcoma and synovial sarcoma. Valuable work regarding brachytherapy has been done by radiation oncologists from the TMH, especially in pediatric patients.

    Full Text Available Sarcoma includes some of the most heterogeneous tumors, which make the diagnosis, prognosis and treatment of these rare yet diverse neoplasms especially challenging. Long noncoding RNAs (lncRNAs are important regulators of cancer initiation and progression, which implies their potential as neoteric prognostic and diagnostic markers in cancer, including sarcoma. A relationship between lncRNAs and sarcoma pathogenesis and progression is emerging. Recent studies demonstrate that lncRNAs influence sarcoma cell proliferation, metastasis, and drug resistance. Additionally, lncRNA expression profiles are predictive of sarcoma prognosis. In this review, we summarize contemporary advances in the research of lncRNA biogenesis and functions in sarcoma. We also highlight the potential for lncRNAs to become innovative diagnostic and prognostic biomarkers as well as therapeutic targets in sarcoma.

    This study investigates how cancer survivors construct their identities and the impact on their psychological health, as measured by depression and survivor self-efficacy. Fourteen young adult survivors of pediatric cancer participated in a customized social networking and video blog intervention program, the LIFECommunity, over a 6-month period. Survivors were asked to share their stories on various topics by posting video messages. Those video blog postings, along with survey data collected from participants, were analyzed to see how cancer survivors expressed their identities, and how these identities are associated with survivors' psychosocial outcomes. In survivors who held negative stereotypes about cancer survivors, there was a positive relationship with depression while positive stereotypes had a marginal association with cancer survivor efficacy. Findings indicate that although pediatric cancer survivors often do not publicly discuss a "cancer survivor identity," they do internalize both positive and negative stereotypes about cancer survivorship. It is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.

    2017-01-01

    Kaposi's sarcoma-associated herpesvirus (KSHV) is etiologically related to Kaposi's sarcoma (KS), primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD). It typically displays two different phases in its life cycle, the default latency and occasional lytic replication. The epigenetic modifications are thought to determine the fate of KSHV infection. Previous studies elegantly depicted epigenetic landscape of latent viral genome in in vitro cell culture systems. However, the physiologically relevant scenario in clinical KS tissue samples is unclear. In the present study, we established a protocol of ChIP-Seq for clinical KS tissue samples and mapped out the epigenetic landscape of KSHV genome in classic KS tissues. We examined AcH3 and H3K27me3 histone modifications on KSHV genome, as well as the genome-wide binding sites of latency associated nuclear antigen (LANA). Our results demonstrated that the enriched AcH3 was mainly restricted at latent locus while H3K27me3 was widespread on KSHV genome in classic KS tissues. The epigenetic landscape at the region of vIRF3 gene confirmed its silenced state in KS tissues. Meanwhile, the abundant enrichment of LANA at the terminal repeat (TR) region was also validated in the classic KS tissues, however, different LANA binding sites were observed on the host genome. Furthermore, we verified the histone modifications by ChIP-qPCR and found the dominant repressive H3K27me3 at the promoter region of replication and transcription activator (RTA) in classic KS tissues. Intriguingly, we found that the TR region in classic KS tissues was lacking in AcH3 histone modifications. These data now established the epigenetic landscape of KSHV genome in classic KS tissues, which provides new insights for understanding KSHV epigenetics and pathogenesis. PMID:28118409

  10. Kaposi's sarcoma-associated herpesvirus infection and Kaposi's sarcoma in Brazil

    S. Ramos-da-Silva

    2006-05-01

    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.

    Suicide has become a major public health problem worldwide. For every suicide there are six suicide survivors, a term referring to family members or friends of a person who has died by suicide. Within the literature there has been ongoing debate regarding the bereavement process and if it differs in survivors of suicide as opposed to survivors of those who have died from accidental death. There are scarcely any published reports on comparison between these two groups of survivors in China. In this study, we aimed to explore the difference of mental health status between suicide survivors and survivors of accidental deaths in China. We used a cross-sectional study design to collect data of survivors. Consecutive sampling was used and 92 suicide survivors and 64 survivors of accidental deaths were interviewed. The Symptom Checklist-90-Revised was used to assess the survivors' mental health status. After controlling for demographic variables and time interval between death and interview, no significant differences were found on mental health status between these two groups of survivors. Several explanations might account for the lack of differences. Further studies employing qualitative measures and suicide-specific instruments are needed to explore the bereavement of Chinese suicide survivors.

  12. Snail1 Expression Is Required for Sarcomagenesis

    Full Text Available Snail1 transcriptional repressor is a major inducer of epithelial-to mesenchymal transition but is very limitedly expressed in adult animals. We have previously demonstrated that Snail1 is required for the maintenance of mesenchymal stem cells (MSCs, preventing their premature differentiation. Now, we show that Snail1 controls the tumorigenic properties of mesenchymal cells. Increased Snail1 expression provides tumorigenic capabilities to fibroblastic cells; on the contrary, Snail1 depletion decreases tumor growth. Genetic depletion of Snail1 in MSCs that are deficient in p53 tumor suppressor downregulates MSC markers and prevents the capability of these cells to originate sarcomas in immunodeficient SCID mice. Notably, an analysis of human sarcomas shows that, contrarily to epithelial tumors, these neoplasms display high Snail1 expression. This is particularly clear for undifferentiated tumors, which are associated with poor outcome. Together, our results indicate a role for Snail1 in the generation of sarcomas.

    Functional impairment resulting from a stroke frequently requires the care of a family caregiver, often the spouse. This change in the relationship can be stressful for the couple. Thus, this study examined the longitudinal, dyadic relationship between caregivers' and stroke survivors' mutuality and caregivers' and stroke survivors' perceived stress. This secondary data analysis of 159 stroke survivors and their spousal caregivers utilized a cross-lagged, mixed models analysis with the actor-partner interdependence model to examine the dyadic relationship between mutuality and perceived stress over the first year post-discharge from inpatient rehabilitation. Caregivers' mutuality showed an actor effect (β = -3.82, p caregivers' mutuality influenced one's own perceived stress but not the stroke survivors' perceived stress. Stroke survivors' perceived stress showed a partner effect and affected caregivers' perceived stress (β = 0.13, p = 0.047). Caregivers' perceived stress did not show a partner effect and did not significantly affect stroke survivors' perceived stress. These findings highlight the interpersonal nature of stress in the context of caregiving for a spouse. Caregivers are especially influenced by perceived stress in the spousal relationship. Couples should be encouraged to focus on positive aspects of the caregiving relationship to mitigate stress.

  16. Microsatellites with Macro-Influence in Ewing Sarcoma

    Stephen L. Lessnick

    2012-07-01

    Full Text Available Numerous molecular abnormalities contribute to the genetic derangements involved in tumorigenesis. Chromosomal translocations are a frequent source of these derangements, producing unique fusion proteins with novel oncogenic properties. EWS/ETS fusions in Ewing sarcoma are a prime example of this, resulting in potent chimeric oncoproteins with novel biological properties and a unique transcriptional signature essential for oncogenesis. Recent evidence demonstrates that EWS/FLI, the most common EWS/ETS fusion in Ewing sarcoma, upregulates gene expression using a GGAA microsatellite response element dispersed throughout the human genome. These GGAA microsatellites function as enhancer elements, are sites of epigenetic regulation and are necessary for EWS/FLI DNA binding and upregulation of principal oncogenic targets. An increasing number of GGAA motifs appear to substantially enhance EWS/FLI-mediated gene expression, which has compelling biological implications as these GGAA microsatellites are highly polymorphic within and between ethnically distinct populations. Historically regarded as junk DNA, this emerging evidence clearly demonstrates that microsatellite DNA plays an instrumental role in EWS/FLI-mediated transcriptional regulation and oncogenesis in Ewing sarcoma. This unprecedented role of GGAA microsatellite DNA in Ewing sarcoma provides a unique opportunity to expand our mechanistic understanding of how EWS/ETS fusions influence cancer susceptibility, prognosis and transcriptional regulation.

  18. Stem-Like Cells in Bone Sarcomas: Implications for Tumorigenesis

    2005-11-01

    Full Text Available Bone sarcomas are a clinically and molecularly heterogeneous group of malignancies characterized by varying degrees of mesenchymal differentiation. Despite advances in medical and surgical management, survival rates for high-grade tumors have remained static at 50% to 70%. Tumor stem cells have been recently implicated in the pathogenesis of other heterogeneous, highly malignant tumors. We demonstrate here the existence of a small subpopulation of self-renewing bone sarcoma cells that are capable of forming suspended spherical, clonal colonies, also called “sarcospheres,” in anchorage-independent, serum-starved conditions. These bone sarcoma cells as well as tissue specimens express activated STAT3 and the marker genes of pluripotent embryonic stem (ES cells, Oct 3/4 and Nanog. Expression levels of Oct 3/4 and Nanog are greater in sarcospheres than in adherent cultures. A subset of bone sarcoma cells displays several surface markers of mesenchymal stem cells (Stro-1, CD105, and CD44 as well as attributes of mesodermal, ectodermal, and endodermal differentiation. Although previously documented in brain and breast tumors, our results support the extension of the cancer stem cell hypothesis to include tumors of mesenchymal lineage. Furthermore, they suggest the participation of ES cell homeobox proteins in non-germ cell tumorigenesis.

    Full Text Available A 1.5 year old, female, spayed, Labrador retriever with a history of three abdominal surgeries within the previous two months presented to the North Carolina State University Veterinary Teaching Hospital for evaluation of a pelvic inlet mass causing fecal tenesmus, obstipation, and dysuria. Abdominal ultrasound revealed a caudal abdominal mass extending into the pelvic cavity. Cytologic evaluation of the mass showed a pleomorphic round to fusiform cell population with histiocytic and suppurative inflammation. The primary differential was neoplasia, but inflammation with cellular pleomorphism could not be excluded. Via histopathology and immunohistochemistry, a diagnosis of poorly differentiated sarcoma originating from the uterus or cervix with widespread intra-abdominal dissemination and metastasis was made. Sarcomas of any type are rare in young dogs with only sporadic cases of poorly or undifferentiated sarcomas reported. This case is a unique presentation of an aggressive, poorly differentiated sarcoma arising from the cervix or uterus in a young dog and illustrates the importance of histologic evaluation of surgically resected tissues that are abnormal in appearance.

    2011-01-01

    Full Text Available Ewing's sarcoma is the second most common bone malignancy affecting children and young adults. The prognosis is especially poor in metastatic or relapsed disease. The cell of origin remains elusive, but the EWS-FLI1 fusion oncoprotein is present in the majority of cases. The understanding of the molecular basis of Ewing's sarcoma continues to progress slowly. EWS-FLI1 affects gene expression, but other factors must also be at work such as mutations, gene copy number alterations, and promoter methylation. This paper explores in depth two molecular aspects of Ewing's sarcoma: copy number alterations (CNAs and methylation. While CNAs consistently have been reported in Ewing's sarcoma, their clinical significance has been variable, most likely due to small sample size and tumor heterogeneity. Methylation is thought to be important in oncogenesis and balanced karyotype cancers such as Ewing's, yet it has received only minimal attention in prior studies. Future CNA and methylation studies will help to understand the molecular basis of this disease.

    The radiobiological properties of the hadrons (neutrons, protons, carbon ions) led to their therapeutic use in sarcomas, as a referent therapy or as an alternative to photon therapy. An extensive review of the literature has been conducted to assess the present indications and the perspectives for hadrontherapy. Compared to photons, neutrons are characterized by a higher biological efficiency that is on particular importance for these tumours usually considered as radio-resistant. Neutrons have been considered as a standard therapy for sarcoma' patients, contra-indicated for surgery or with a definitive R2 resection, but their indications and use have been restricted due to the occurrence of late severe toxicities related to their poor ballistic' properties. Thanks to their physical properties (Bragg Peak), protons are characterized by a higher conformity index compared to photons (and neutrons) with optimal organs at risk preservation that permits a dose escalation. Protontherapy is to date the standard of care for base of skull, spinal and paraspinal sarcomas. Carbon ions combined both advantages from protons and neutrons. Literature data permits to consider this radiation modality as a referent therapy for unresectable sarcomas. The ongoing diffusions of protons and carbon ions radiotherapy facilities will permit to offer these therapies to more patients and to conduct studies that are warranted to determine their indications and their results.

  10. Functional Reconstruction of Sarcoma Defects Utilising Innervated Free Flaps

    2012-01-01

    Full Text Available Soft-tissue reconstruction following preoperative radiotherapy and wide resection of soft tissue sarcoma remains a challenge. Pedicled and free tissue transfers are an essential part of limb sparing surgery. We report 22 cases of sarcoma treated with radiotherapy and wide excision followed by one-stage innervated free or pedicled musculocutaneous flap transfers. The resection involved the upper limb in 3 cases, the lower limb in 17, and the abdominal wall in 2. The flaps used for the reconstruction were mainly latissimus dorsi and gracilis. The range of motion was restored fully in 14 patients. The muscle strength of the compartment reconstructed was of grades 4 and 5 in all patients except one. The overall function was excellent in all the cases with functional scores of 71.2% in the upper limb and 84% in the lower limb. The only 2 major complications were flap necrosis, both revised with another flap, one of which was innervated with restoration of function. Innervated flaps are valuable alternatives for reconstruction after sarcoma resection in the extremity and in the abdominal wall. The excellent functional results are encouraging, and we believe that innervated muscle reconstruction should be encouraged in the treatment of sarcoma after radiotherapy and wide resection.

    Soft tissue sarcomas (STS) are a heterogeneous group of tumors of mesodermal origin. Although they are rare, nearly half of patients diagnosed will die from the disease at last, which almost has not been changed in recent decades. STS can occur any where in the body, but the majority of primary tumors originate in extremities. Accurate pretreatment evaluation is critical and the management requires a multidisciplinary approach which includes various combinations of surgery, radiotherapy, and chemotherapy. Treatment aims to ensure long term survival, avoid local recurrence, and maximize patient function while minimizing morbidity. Surgery is the mainstay of treatment in patients with localized disease and ideal primary therapy for resectable tumors. Limb salvage surgery is the standard of care for most patients with soft tissue sarcoma of the extremities. But in many cases, there exist large primary tumors, bulky recurrent tumors, tumors invading critical neurovascular structures, tumor cells which have already transferred to other parts of the body and so on, other treatments like radiotherapy or chemotherapy may be needed. Controversy still exists for isolated limb perfusion (ILP) in the treatment of unresectable extremity sarcomas. ILP has been widely used in European countries already, but it is still in the clinical trial in America at present. This overview is intended as a review of current understanding and treatment of STS, with an emphasis on recent advances.

    The present study examined change on emotional distress of sarcoma patients from the diagnostic to treatment phases, the distinct trajectories of adjustment and the influence of demographic, clinical and coping variables on anxiety and depression. Thirty-six sarcoma patients completed questionnaires on emotional distress (Hospital Anxiety and Depression Scale) and coping strategies (Brief Cope) at time of diagnosis, and again during treatment. No significant change in emotional distress levels was found from diagnostic to treatment phase, with mean anxiety and depression scores remaining below the clinical range. Over time, 52.8% and 66.7% of patients maintained non-clinical anxious and depressive symptoms respectively, and 25% and 11.1% remained with clinical anxiety and depression. Living with partner, less use of humour and more denial were associated with high emotional distress at time of diagnosis and during treatments, and high levels of distress at baseline were predictive of poorer emotional adjustment during treatments. Although sarcoma patients, in general, seem to exhibit good psychological adjustment, there is a significant minority that requires mental health services in order to help decrease their emotional distress following the diagnosis, and prevent psychological difficulties during treatments. Our findings are an important contribution to understanding the psychological adjustment of patients with a specific and rare type of cancer.

    The number of survivors actually registered with the Committee of A-bomb survivors in the U.S. is 491 (133 males and 358 females) of whom 57.3% are U.S. citizens. Those exposed in Hiroshima accounted for 91.8%. The mean age was 53.3 +- 8.9, thus they were more than 3 years younger than their counterparts in Hiroshima. Responses to the Health Survey Questionnaires numbered 255, and those with symptoms which appeared to be related to diseases were found at a high rate among the early entrants, but as the number of those receiving examination in this group was few, it is considered that many of those in poor health had come in for the examination. No association could be demonstrated between psychological complaints and exposure status. Those who underwent health examination numbered 166 (45 males and 121 females), and comparison of the U.S. survivors against the Hiroshima survivors showed there to be a difference in the following points. The prevalence of hypertension was lower among the U.S. survivors, but RBC counts and hemoglobin values were significantly higher. The same was observed for blood lipids with hypercholesterolemia and hypertriglyceridemia being found at a significantly higher rate in the U.S. survivors, the cause being considered to be the larger intake of animal fat and sugar by those of Japanese ancestry than the indigenous Japanese. Those free of clinical abnormalities in this survey were 37.3%, and the rest required dietary guidance, follow-up observation, detailed examination or treatment. Those with diseases which are considered would make them eligible for health management allowance if in Japan, accounted for 18.7%.

    Observational evidence has established a relationship between obesity and cancer risk and outcomes. Interventional studies have demonstrated the feasibility and benefits of lifestyle change after cancer diagnosis, and guidelines recommend weight management and regular physical activity in cancer survivors; however, lifestyle interventions are not a routine part of cancer care. The ASCO Research Summit on Advancing Obesity Clinical Trials in Cancer Survivors sought to identify the knowledge gaps that clinical trials addressing energy balance factors in cancer survivors have not answered and to develop a roadmap for the design and implementation of studies with the potential to generate data that could lead to the evidence-based incorporation of weight management and physical activity programs into standard oncology practice. Recommendations highlight the need for large-scale trials evaluating the impact of energy balance interventions on cancer outcomes, as well as the concurrent conduct of studies focused on dissemination and implementation of interventions in diverse populations of cancer survivors, including answering critical questions about the degree of benefit in key subgroups of survivors. Other considerations include the importance of incorporating economic metrics into energy balance intervention trials, the need to establish intermediate biomarkers, and the importance of integrating traditional and nontraditional funding sources. Establishing lifestyle change after cancer diagnosis as a routine part of cancer care will require a multipronged effort to overcome barriers related to study development, funding, and stakeholder engagement. Given the prevalence of obesity and inactivity in cancer survivors in the United States and elsewhere, energy balance interventions hold the potential to reduce cancer morbidity and mortality in millions of patients, and it is essential that we move forward in determining their role in cancer care with the same care and

    Full Text Available Abstract Background Sarcomas are rare tumors (1-2% of all cancers of mesenchymal origin that may develop in soft tissues and viscera. Since the International Classification of Disease (ICD attributes visceral sarcomas (VS to the organ of origin, the incidence of sarcoma is grossly underestimated. The rarity of the disease and the variety of histological types (more than 70 or locations account for the difficulty in acquiring sufficient personal experience. In view of the above the European Commission funded the project called Connective Tissues Cancers Network (CONTICANET, to improve the prognosis of sarcoma patients by increasing the level of standardization of diagnostic and therapeutic procedures through a multicentre collaboration. Methods/Design Two protocols of epidemiological researches are here presented. The first investigation aims to build the population-based incidence of sarcoma in a two-year period, using the new 2002 WHO classification and the "second opinion" given by an expert regional pathologist on the initial diagnosis by a local pathologist. A three to five year survival rate will also be determined. Pathology reports and clinical records will be the sources of information. The second study aims to compare the effects on survival or relapse-free period - allowing for histological subtypes, clinical stage, primary site, age and gender - when the disease was treated or not according to the clinical practice guidelines (CPGs. Discussion Within CONTICANET, each group was asked to design a particular study on a specific objective, the partners of the network being free to accept or not the proposed protocol. The first protocol was accepted by the other researchers, therefore the incidence of sarcoma will be assessed in three European regions, Rhone-Alpes and Aquitaine (France and Veneto (Italy, where the geographic distribution of sarcoma will be compared after taking into account age and gender.

    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.

    Anaplastic Kaposi sarcoma (AKS), a rare variant of Kaposi sarcoma, has a poorly recognized histomorphologic spectrum, including a paucivascular phenotype, that mimics a range of undifferentiated malignancies. This study, that highlights the hitherto undocumented phenomenon of S100-protein-positive Langerhans cells (SLCs) as a potential diagnostic pitfall in paucivascular AKS, involved review of nine such AKS that required diagnostic immunohistochemical (IHC) work-up. All biopsies had a predominant or exclusive spindle or epithelioid cell infiltrate. The first three tumors were diagnosed as malignant peripheral nerve sheath tumor (2) and metastatic melanoma (1), based on S100-protein immunopositivity. Biopsy of a co-existent pigmented sole lesion (patient 3) demonstrated nodular KS. Subsequent IHC investigation of these three tumors demonstrated an endothelial phenotype and HHV8 immunopositivity, confirming AKS. CD1a and langerin staining of the S100-protein-positive cells confirmed Langerhans cells as the cause of the diagnostic pitfall. Subsequently, six further paucivascular AKS with intratumoral SLCs were recognized on histomorphological and IHC appraisal. In conclusion, heightened awareness of the histomorphologic spectrum, appropriate IHC investigation, and informed appraisal thereof, are critical to the diagnosis of AKS with an undifferentiated phenotype, and the avoidance of IHC pitfalls, such as those caused by under-recognition and misinterpretation of bystander SLCs in AKS.

    2011-01-01

    Mycetoma, also commonly referred to as Madura foot, is statistically rare in the United States. However, it is endemic to other parts of the world. It is a pseudotumor characterized by a triad of tumefaction, draining sinuses, and grains. Two types exist, with each caused by different groups of organisms that require different treatment approaches. Therefore, the exact diagnosis and culture of the organism is vital to successful treatment outcomes. Synovial sarcoma, in contrast, is a malignancy much more commonly seen in the United States. It is characterized by a well-circumscribed, often palpable, mass that is usually well delineated on magnetic resonance imaging. It has characteristic histologic and genetic features that help distinguish it from other soft tissue masses. We present a case of a soft tissue mass diagnosed in the United States. The patient had several clinical and radiographic features of synovial sarcoma but the histologic outcome was mycetoma. The case is followed by a review of the published data.

    The development of metastases is a multistep process that requires the activation of physiological and biochemical processes that govern migration, invasion and entry of metastatic cells into blood vessels. The urokinase receptor (uPAR) promotes cell migration by interacting with the Formyl Peptide Receptors (FPRs). Since both uPAR and FPR1 are involved in tumor progression, the uPAR-FPR1 interaction is an attractive therapeutic target. We previously described peptide antagonists of the uPAR-FPR1 interaction that inhibited cell migration and angiogenesis. To develop enzyme-resistant analogues, we applied here the Retro-Inverso (RI) approach, whereby the topology of the side chains is maintained by inverting the sequence of the peptide and the chirality of all residues. Molecular dynamics suggests that peptide RI-3 adopts the turn structure typical of uPAR-FPR1 antagonists. Accordingly, RI-3 is a nanomolar competitor of N-formyl-Met-Leu-Phe for binding to FPR1 and inhibits migration, invasion, trans-endothelial migration of sarcoma cells and VEGF-triggered endothelial tube formation. When sarcoma cells were subcutaneously injected in nude mice, tumor size, intra-tumoral microvessel density, circulating tumor cells and pulmonary metastases were significantly reduced in animals treated daily with 6 mg/Kg RI-3 as compared to animals treated with vehicle only. Thus, RI-3 represents a promising lead for anti-metastatic drugs.

    Full Text Available Intimal (spindle cell sarcomas of the left atrium are extremely rare primary cardiac tumours with three cases reported (Li et al. (2013, Cho et al. (2006, and Modi et al. (2009. We present a 69-year-old man who first came to medical attention after experiencing abdominal discomfort. He had a 30 lb weight loss apparently due to dieting. He denied any other constitutional symptoms. His symptoms persisted despite a course of antibiotics for presumed diverticulitis. Laboratory values were within normal limits, though the haemoglobin was 131 g/L (normal: 140–180. Subsequent abdominal computed tomography (CT scan revealed an abdominal wall mass and intracardiac lesion; the cardiac mass was further characterized by transesophageal echo (TEE, magnetic resonance imaging (MRI, and dedicated cardiac CT. TEE revealed a mass attached to the posterolateral wall of the left atrium above the mitral annulus, and the cardiac CT and MRI confirmed the TEE findings. The patient underwent extensive surgical resection and repair of the left side of the heart. Postoperatively, he developed acute renal failure requiring dialysis and reintubation for volume overload. He became acutely hypotensive, developed multiorgan failure, and succumbed to his illness. Histopathologic examination of the left atrial mass showed an intimal sarcoma.

    To determine the association of symptom burden to work limitation among working survivors of malignant brain tumors. Working adults with malignant brain tumors (n = 95) and a non-cancer comparison (n = 131) group completed a web-based questionnaire. Measures of demographics, tumor type and treatment, fatigue, emotional distress, cognitive limitations, and factors that can positively impact work, including health behaviors and problem solving, were obtained. Survivors of malignant brain tumors reported higher levels of work limitations and time off from work than the non-cancer group. Higher levels of symptom burden, lower levels of health behaviors, and more negative problem solving orientation were characteristic of the brain tumor survivor group. These variables were not differentially associated with work limitations among brain cancer survivors or the comparison group. Depressive symptoms, fatigue, cognitive limitations, sleep, and negative problem solving orientation were independently associated with work limitations, accounting for 65% of the variance in work limitations. Despite higher levels of burden, poorer health behaviors, and negative problem solving coping style, modifiable factors account for most of the variance in work limitations for both groups. Efforts to modify these variables should be evaluated.

    Objectives A review is made of the clinical, diagnostic, therapeutic and survival characteristics of Ewing sarcoma (ES) of the oral cavity. Material and Methods A systematic literature search was carried out, with restrictions referred to time (1960-2014), language (English and Spanish) and type of study (case reports, letters, datasets, reviews). The following MeSH terms and boolean operators were used: Ewing AND Sarcoma AND [tongue, jaw, maxilla, cheek, condyle OR temporomandibular, floor AND mouth, gum OR gingiva, palate OR palatal, lip, uvula, head AND neck]. Results Seventy-one cases of ES of the oral cavity were documented from 53 articles. The main differences versus ES of other locations were a younger age at manifestation, a shorter time from symptoms onset to diagnosis, and swelling as the most frequent clinical manifestation versus swelling and pain in the rest of disease locations. The way in which ES manifests in the oral cavity is varied and comprises dental displacement (19.7%), dental mobility (7%), root reabsorption (5.6%), destruction of the dental follicle (4.2%), premature exfoliation (4.2%) and paresthesia of the chin (2.8%). Metastatic neck adenopathies appear in 11.3% of the cases. Significant differences in survival are observed between patients with a complete diagnosis of ES (hematoxylin-eosin staining, PAS positivity, CD99 positivity) and those with an incomplete diagnosis. Conclusions Ewing sarcoma of the oral cavity presents a series of specific features that distinguish it from ES of other locations. Key words:Primitive neuroectodermal tumor, PNET, Ewing sarcoma, Ewing tumor, sarcoma, oral cavity. PMID:28210452

    Purpose: To review long-term outcomes following postoperative radiotherapy (RT) for extremity soft tissue sarcoma (STS) and identify variables affecting the therapeutic ratio. Methods and Materials: Between 1970 and 2008, 173 patients with localized extremity STS were treated with postoperative radiation. No patients received prior irradiation. Sixteen percent of tumors had recurred after initial surgery alone; 89% of tumors were high grade. The median patient age was 57 years (range, 18-86 years). Sixty-one percent underwent >1 surgery before RT in an attempt to achieve wide negative margins. Final margin status was negative in 70% and marginal or microscopically positive in 30%. The median time between final surgery and start of RT was 40 days. The median RT dose was 65 Gy (range, 49-74 Gy). The median follow-up for all patients was 10.4 years and 13.2 years among survivors. Results: At 10 years, local control (LC), cause-specific survival (CSS), and overall survival (OS) rates were 87%, 80%, and 70%, respectively, with 89% of local failures occurring within 3 years after treatment. On multivariate analysis, age >55 years (82% vs 93%, P<.05) and recurrent presentation (67% vs 91%, P<.05) were associated with inferior 10-year LC. The LC according to final margin status was 90% for wide negative margins vs 79% for marginal/microscopically positive margins (P=.08). Age >55 years and local recurrence were associated with inferior CSS and OS on multivariate analysis. Twelve percent of patients experienced grade 3+ toxicity; 12 of these occurred in patients with tumors of the proximal lower extremity, with the most common toxicity of pathologic fracture occurring in 6.3%. Conclusions: This large single-institution series confirms that postoperative RT for STS of the extremities provides good long-term disease control with acceptable toxicity. Our experience supports recurrent presentation and older age as adverse prognostic factors for LC.

    Purpose: To evaluate feasibility and patterns of failure in adult patients with Ewing sarcoma (ES) treated with whole lung irradiation (WLI) for pulmonary metastases. Methods and Materials: Retrospective review of all ES patients treated at age 18 or older with 12-15 Gy WLI for pulmonary metastases at a single institution between 1990 and 2014. Twenty-six patients met the study criteria. Results: The median age at WLI was 23 years (range, 18-40). The median follow-up time of the surviving patients was 3.8 years (range, 1.0-9.6). The 3-year cumulative incidence of pulmonary relapse (PR) was 55%, with a 3-year cumulative incidence of PR as the site of first relapse of 42%. The 3-year event-free survival (EFS) and overall survival (OS) were 38 and 45%, respectively. Patients with exclusively pulmonary metastases had better outcomes than did those with extrapulmonary metastases: the 3-year PR was 45% in those with exclusively lung metastases versus 76% in those with extrapulmonary metastases (P=.01); the 3-year EFS was 49% versus 14% (P=.003); and the 3-year OS was 61% versus 13% (P=.009). Smoking status was a significant prognostic factor for EFS: the 3-year EFS was 61% in nonsmokers versus 11% in smokers (P=.04). Two patients experienced herpes zoster in the radiation field 6 and 12 weeks after radiation. No patients experienced pneumonitis or cardiac toxicity, and no significant acute or late sequelae were observed among the survivors. Conclusion: WLI in adult patients with ES and lung metastases is well tolerated and is associated with freedom from PR of 45% at 3 years. Given its acceptable toxicity and potential therapeutic effect, WLI for pulmonary metastases in ES should be considered for adults, as it is in pediatric patients. All patients should be advised to quit smoking before receiving WLI.
