BACKGROUND: Lymphedema is an iatrogenic complication after breast cancer treatment in which lymph fluid in the affected limb progresses to fat deposition and fibrosis that are amenable to liposuction treatment. Magnetic resonance imaging (MRI) for lymphedema can differentiate fat tissue from fluid, but estimating relative volumes remains problematic. METHODS AND RESULTS: Patients underwent routine bilateral arm MRI both before and after liposuction for advanced lymphedema...

BACKGROUND: The prognostic significance of markers of the systemic inflammatory response in patients with soft tissue and bone sarcomas remains unclear. Therefore, the present study aimed to compare the prognostic value of markers of the systemic inflammatory response in patients undergoing surgery for primary soft tissue and bone sarcoma. METHOD: Patients who underwent resection of primary soft tissue/bone sarcoma between 2008 and 2012 and had pre-operative measurements of the systemic inflammatory response [C-reactive protein, albumin, white cell, neutrophil, lymphocyte and platelet counts, and the combination of C-reactive protein and albumin (mGPS)] were included in the study (n = 111)...

The development of smart nanocarriers for the delivery of therapeutic drugs has experienced considerable expansion in recent decades, with the development of new medicines devoted to cancer treatment. In this respect a wide range of strategies can be developed by employing liposome nanocarriers with desired physico-chemical properties that, by exploiting a combination of a number of suitable soft interactions, can facilitate the transit through the biological barriers from the point of administration up to the site of drug action...

Nowadays, surgery, radiotherapy and chemotherapy are the most frequently used modalities in the treatment of breast cancer. It is very well-known that some severe complications may result from after these treatments. Early and late complications of radiotherapy are well known. The complications of radiation therapy may be seen in (early) or after three months (late-delayed) of periods. These complications may be related with direct or indirect effect of radiation. The radiation fibrosis syndrome is a progressive fibrotic tissue sclerosis together with various clinical symptoms in the irradiation field...

The management of soft tissue sarcoma is challenging and varied. Centralisation of management in high volume specialist centres has revolutionised outcomes. Surgery remains the mainstay of treatment and is currently the only potentially curative therapy. Retroperitoneal soft tissue sarcoma presents a particular challenge to the surgical oncologist and the concept of extended resection to include surrounding expendable organs taken en bloc with the tumour has now largely been adopted. The use of neoadjuvant and adjuvant therapies for retroperitoneal soft tissue sarcoma is still to be established, although they are employed on a case-specific basis...

BACKGROUND: One approach to identify patients who meet specific eligibility criteria for target-based clinical trials is to use patient and tumor registries to prescreen patient populations. OBJECTIVE: Here we demonstrate that the Total Cancer Care (TCC) Protocol, an ongoing, observational study, may provide a solution for rapidly identifying patients with CD30-positive tumors eligible for CD30-targeted therapies such as brentuximab vedotin. METHODS: The TCC patient gene expression profiling database was retrospectively screened for CD30 gene expression determined using HuRSTA-2a520709 Affymetrix arrays (GPL15048)...

Ewing Sarcoma is the second most common solid pediatric malignant neoplasm of bone and soft tissue. Driven by EWS/Ets, or rarely variant, oncogenic fusions, Ewing Sarcoma is a biologically and clinically aggressive disease with a high propensity for metastasis. However, the mechanisms underpinning Ewing Sarcoma metastasis are currently not well understood. In the present study, we identify and characterize a novel metastasis-promotional pathway in Ewing Sarcoma, involving the histone demethylase KDM3A, previously identified by our laboratory as a new cancer-promoting gene in this disease...

In image-guided radiotherapy (IGRT) of prostate cancer, delineation of the clinical target volume (CTV) often relies on magnetic resonance (MR) because of its good soft-tissue visualization. Registration of MR and computed tomography (CT) is required in order to add this accurate delineation to the dose planning CT. An automatic approach for local MR-CT registration of the prostate has previously been developed using a voxel property-based registration as an alternative to a manual landmark-based registration...

The purpose of this study is to use the same diagnostic-quality verification and planning CTs to validate planning margin account for residual interfractional variations with image-guided soft tissue alignment of the prostate. For nine prostate cancer patients treated with IMRT to 78 Gy in 39 fractions, daily verification CT-on-rails images of the first seven and last seven fractions (n=126) were retrospectively selected for this study. On these images, prostate, bladder, and rectum were delineated by the same attending physician...

William B. Coley developed bacterial therapy of cancer more than 100 years ago and had clinical success. James Ewing, a very famous cancer pathologist for whom the Ewing sarcoma is named, was Coley's boss at Memorial Hospital in New York and terminated Coley's bacterial therapy of cancer. A tumor from a patient with soft-tissue Ewing's sarcoma, who failed doxorubicin (DOX) therapy, was previously implanted in nude mice to establish a patient-derived orthotopic xenograft (PDOX) model. In the present study, the Ewing's sarcoma PDOX was treated with tumor-targeting S...

BACKGROUND: In a placebo-controlled, randomized phase 2 trial (ClinicalTrials.gov identifier NCT01900743), regorafenib improved progression-free survival (PFS) for patients with doxorubicin-pretreated advanced nonadipocytic sarcoma. A quality-adjusted time without symptoms of progression or toxicity (Q-TWiST) post hoc exploratory analysis was applied to provide an integrated measure of its clinical benefit. METHODS: In the base-case analysis, each patient's overall survival (OS) was partitioned into 3 mutually exclusive health states: the time with a grade 3 or 4 adverse event (TOX), the time without symptoms of disease or grade 3 or 4 toxicity from treatment, and the time after tumor progression or relapse...

Soft tissue sarcomas (STS) are malignant tumours of mesenchymal origin and represent around 1% of adult cancers, being a very heterogeneous group of tumours with more than 50 different subtypes. The Wnt signalling pathway is involved in the development and in the regulation, self-renewal and differentiation of mesenchymal stem cells and plays a role in sarcomagenesis. In this study we have tested pharmacological inhibition of Wnt signalling mediated by disruption of TCF/β-catenin binding and AXIN stabilization, being the first strategy more efficient in reducing cell viability and downstream effects...

The intraoperative cytological assessment of bony resection margins (ICAB) is a feasible diagnostic approach to support frozen section for assessment of invasion of margins of soft and hard tissue. However, complex resection margins could challenge both diagnostic approaches. Our objective here was to identify the limitations of intraoperative diagnostic methods for assessing margins. We present an advanced cytological approach to assess complex margins that may solve the problem. Data from 119 patients in whom frozen section was supported by ICAB, were reviewed and the reasons for false results analysed...

BACKGROUND: Childhood and adolescent cancers are uncommon, but they have important economic and health impacts on patients, families, and health care systems. Few studies have measured the economic burden of care for childhood and adolescent cancers. OBJECTIVES: To estimate costs of cancer care in population-based cohorts of children and adolescents from the public payer perspective. METHODS: We identified patients with cancer, aged 91 days to 19 years, diagnosed from 1995 to 2009 using cancer registry data, and matched each to three noncancer controls...

We reviewed available evidence on coffee drinking and the risk of all cancers and selected cancers updated to May 2016. Coffee consumption is not associated with overall cancer risk. A meta-analysis reported a pooled relative risk (RR) for an increment of 1 cup of coffee/day of 1.00 [95% confidence interval (CI): 0.99-1.01] for all cancers. Coffee drinking is associated with a reduced risk of liver cancer. A meta-analysis of cohort studies found an RR for an increment of consumption of 1 cup/day of 0.85 (95% CI: 0...

(177)Lu has sprung as a promising radionuclide for targeted therapy. The low soft tissue penetration of its β(-) emission results in very efficient energy deposition in small-size tumours. Because of this, (177)Lu is used in the treatment of neuroendocrine tumours and is also clinically approved for prostate cancer therapy. In this work, we report a separation method that achieves the challenging separation of the physically and chemically identical nuclear isomers, (177m)Lu and (177)Lu. The separation method combines the nuclear after-effects of the nuclear decay, the use of a very stable chemical complex and a chromatographic separation...

Three-dimensional (3D) cell culture models are gaining increasing interest for use in drug development pipelines due to their closer resemblance to human tissues. Hydrogels are the first-choice class of materials to recreate in vitro the 3D extra-cellular matrix (ECM) environment, important in studying cell-ECM interactions and 3D cellular organization and leading to physiologically relevant in vitro tissue models. Here we propose a novel hydrogel platform consisting of a 96-well plate containing pre-cast synthetic PEG-based hydrogels for the simple establishment of 3D (co-)culture systems without the need for the standard encapsulation method...

INTRODUCTION: Myeloid sarcoma (MS) in chronic myeloid leukemia (CML) is a rare entity which is suggestive of advanced phase of the disease and poorer outcomes. There is little data in literature available regarding its presentation in medullary chronic phase (CP) as well as outcomes in the era of tyrosine kinase inhibitors (TKI) and needs to be carefully evaluated as it can present the first sign of progressive disease before haematological progression. METHODS: We identified cases of MS presenting with medullary CML-CP from January 2002 to December 2015...
