AIMS: The consequences of cancer and treatment on fertility can be a continuing source of distress for adolescents and young adults. The study aims were to assess the effects of bundled interventions on clinical practice concerning fertility in young people aged 14-25 years with cancer. METHODS: Bundled interventions, including development of quality indicators, resources, and targeted education, were introduced during 2015 across five cancer centers. Data before interventions (2012-2014) were compared with data prospectively collected during 2015-2016...

Sarcoma, a rare form of cancer, is unlike the much more common carcinomas as it occurs in a distinct type of tissue. The potent antitumor effects of 18β-glycyrrhetinic acid (GA), a novel naturally derived agent, have been demonstrated in various cancers. However, the effect of GA on human sarcoma, and the underlying mechanisms, remain to be elucidated. In the current study, we show that GA inhibits sarcoma cell proliferation by inducing G0/G1-phase arrest. Exposure to GA resulted in the activation of caspase-3, -8, and -9, indicating that GA induced apoptosis through both extrinsic and intrinsic pathways...

OBJECTIVE: Renal tumours apparently are rare not only in cats and dogs, but also in guinea pigs and can be difficult to diagnose. The aim of this study is to describe the clinical, pathological and immunohistochemical findings in guinea pigs with renal tumours. Furthermore, the symptoms, diagnostic possibilities and therapy are compared with renal tumours in other small animals, including cats and dogs. MATERIAL AND METHODS: During a period of 4 years and 4 months the data of guinea pigs that had been presented in the clinic were retrospectively analysed...

Recurrence of a soft tissue sarcoma typically manifests as a round or oval mass at imaging, and recurrent high-grade soft tissue sarcomas generally enlarge relatively rapidly. We present a case of high-grade undifferentiated pleomorphic sarcoma in the calf of a 48-year-old male that recurred as a thin, curvilinear "tail" of enhancing tissue at magnetic resonance imaging (MRI), with extremely indolent growth over a 7-year period. The unusual imaging finding of a slowly enlarging "tail" should not be dismissed as postoperative changes, even for a high-grade soft tissue sarcoma...

Malignant fibrous histiocytoma (MFH) is an aggressive soft tissue sarcoma known to occur in various organs. Primary MFH arising in the lung is quite rare. Herein we report a case of a 61-year-old male with primary pulmonary MFH and explore the underlying molecular mechanisms by next-generation sequencing (NGS). Five gene mutations in TSC2, ARID1B, CDK8, KDM5C and CASP8 were detected, and the mTOR inhibitor might be an effective treatment for this patient. In addition, we reviewed the scientific literature of approximately 23 primary pulmonary MFH case reports since 1990 and summarized the clinical features and prognosis of this rare pulmonary malignant tumor...

Thymic carcinoma is a rare, aggressive disease with a low 5-year survival rate. The most common histological neoplastic thymic tumor subtype is squamous cell. We describe an interesting case of a 39-year-old woman who presented with mucinous adenocarcinoma that originated in the thymus and was treated via radical resection and venoplasty of the superior vena cava (SVC). Macroscopically, the resected tumor contained a solid region and multiple cysts with abundant mucin. Microscopic examination showed a papillary growth pattern of goblet cells with round nuclei...

Liposarcomas are the most common type of mesenchymal neoplasm in soft tissue sarcomas. Although they frequently develop at the lower limbs or retroperitoneum, cases arising from the mediastinum are rare. Furthermore, the incidence of the inflammatory subtype of well-differentiated liposarcoma is known to be low. We experienced a case of a middle mediastinal liposarcoma in a 68-year-old woman. The tumor, which was completely resected, was 92 mm in diameter. The tumor consisted of two different imaging components that showed different growth and which were diagnosed as the lipoma-like subtype and inflammatory subtype of well-differentiated liposarcoma...

BACKGROUND: Studies have shown that the ligand of programmed cell death protein 1 (B7-H1, CD274 or PD-L1) is related to lung cancer driver genes. Although studies have examined the association between lung cancer driver gene mutations or expression and PD-L1 expression, the present studies have not been mined the correlation systematically and genome-widely. METHODS: All relevant published PD-L1 articles with driver genes data and the RNA-seq dataset from The Cancer Genome Atlas (TCGA) were analyzed...

Cancer is a complex group of diseases with multiple eventual causes. The underlying causes are not fully known. Thus, learning more about the known causes of cancer is an important issue. Moreover, among these factors, infection and its association to cancers is controversial. Although, it seems that the genome instability of the cells can initiate cancer development. The purpose of this review was to present the role of infection in the development of cancer. Infectious agents, such as hepatitis B (HBV) and C viruses (HCV), Epstein-Barr virus (EBV), human papillomavirus (HPV), human immunodeficiency virus type 1 (HIV-1), Helicobacter pylori (H...

Soft tissue sarcomas (STS) constitute a heterogeneous group of rare malignant tumors of mesenchymal cell origin and they may develop in any part of the body. They can form enormous masses in certain localizations. A case report of a young woman with locally advanced liposarcoma in the pelvic cavity is presented. This example emphasizes the significance of early diagnosis, as only radical surgery can be potentially curative in sarcoma therapy.Key words: advanced pelvic sarcoma multimodal treatment multidisciplinary...

BACKGROUND: MiRNAs may be associated with the risk of uterine sarcoma and related molecular mechanism remains unclear. METHODS: A total of 101 patients with uterine sarcoma (cases) and 54 healthy subjects (controls) were enrolled. The levels of serum miR-152, miR-205, miR-222, miR-24, miR-150 and sirtuin 1 (SIRT1, an NAD +-dependent class III histone deacetylase) were measured by qRT-PCR. HeLa cells were transfected with the mimics of miR-152 and miR-24. The autophagic rates, and the levels of SIRT1 and acetylation of microtubule-associated protein 1A/1B-light chain 3 (LC3) were measured...

Histiocytic sarcoma (HS) is an aggressive malignant neoplasm of dendritic cell origin that is common in certain breeds of dogs. High prevalence of fatal, disseminated HS has been described in Bernese Mountain Dogs (BMDs). Support for genetic predisposition to develop HS has been presented in several studies, but to date, causative genetic events have not been reported. In addition, no driver mutations have been identified in tumours. Recently, E76K gain-of-function mutation in SHP2 encoded by the PTPN11 gene has been described in human histiocytic malignancies...

Ewing's sarcoma is a malignant, round cell tumor arising from the bones and primarily affecting children and adolescent, accounting for 3 % of all childhood malignancies. Although the long bones and the trunk are typically affected, rare cases of it involving isolated bones throughout the body have been reported. Involvement of the skull bones is rare, constituting 1-6 % of the total Ewing's sarcoma cases but those affecting the cranial bones are rarer still, constituting only 1 %. We describe an 8 months old infant having Ewing sarcoma, of the petrous and mastoid parts of temporal bone along with the occipital bone, whose clinical presentation mimicked mastoiditis with facial nerve palsy...

Objective: The existing literature of 18 F-FDG PET/CT in Ewing sarcoma investigates mixed populations of patients with both soft tissue and bone primary tumors. The aim of our study was to evaluate whether the maximum standardized uptake value (SUVmax) obtained with 18F-FDG PET/CT before and after induction chemotherapy can be used as an indicator of survival in patients with Ewing sarcoma originating exclusively in the skeleton. Materials and Methods: A retrospective database search from 2004-2011 identified 28 patients who underwent 18 F-FDG PET/CT before (SUV1, n= 28) and after (SUV2, n=23) induction chemotherapy...

The aim of the present study was to identify the key genes associated with osteosarcoma (OS) using a bioinformatics approach. Microarray data (GSE36004) was downloaded from the Gene Expression Omnibus database, including 19 OS cell lines and 6 normal controls. Differentially expressed genes (DEGs) in the OS cell lines were identified using the Limma package, and differentially methylated regions were screened with methyAnalysis in R. Copy number analysis was performed and genes with copy number gains/losses were further screened using DNAcopy and cghMCR packages...

Cytoplasmic aggregation of fused in sarcoma (FUS) is detected in brain regions affected by amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), which compose the disease spectrum, FUS proteinopathy. To understand the pathomechanism of ALS-FTD-associated FUS, we examined the behavior and cellular properties of an ALS mouse model overexpressing FUS with nuclear localization signal deletion. Mutant FUS transgenic mice showed hyperactivity, social interactional deficits, and impaired fear memory retrieval, all of which are compatible with FTD phenotypes...

The p53 tumor suppressor is inactivated in most cancers, thus suggesting that loss of p53 is a prerequisite for tumor growth. Therefore, its reintroduction through different means bears great clinical potential. After a brief introduction to current knowledge of p53 and its regulation by the ubiquitin-ligases MDM2/MDMX and post-translational modifications, we will discuss small molecules that are able to reactivate specific, frequently observed mutant forms of p53 and their applicability for clinical purposes...

Myeloid sarcoma (MS) is a localized tumor composed of premature precursors of granulocytic cells, which may occur in any organ and most commonly involves the soft tissue and musculoskeletal system. This malignancy may occur in the presence or absence of hematological disorders. Primary MS involving the central nervous system (CNS-MS) is rare, and has only been described in a small number of isolated case reports. The diagnosis of CNS-MS is challenging and strategies for its management are undefined. The present study describes 4 cases of CNS-MS...
