The mechanical behavior of biological tissues has been studied using a number of mechanical models. Due to the relatively high fluid content and mobility, many biological tissues have been modeled as poroelastic materials. Diseases such as cancers are known to alter the poroelastic response of a tissue. Tissue poroelastic properties such as compressibility, interstitial permeability and fluid pressure also play a key role for the assessment of cancer treatments and for improved therapies. At the present time, however, a limited number of poroelastic models for soft tissues are retrievable in the literature, and the ones available are not directly applicable to tumors as they typically refer to uniform tissues...

BACKGROUND: Surgeons employ the latissimus dorsi flap (LDF) for reconstruction of a large variety of breast cancer surgery defects, including quadrantectomy, lumpectomy, modified radical mastectomy, and others. The LDF may be used in delayed or immediate reconstruction, in combination with tissue expanders for a staged reconstruction, with implant-based immediate reconstruction, or alone as an autogenous flap. METHODS: The authors discuss the historical uses and more recent developments in the LDF...

Together with surgery and radiotherapy, systemic treatment with cytotoxic chemotherapy and molecular targeted agents is one of the main therapeutic pillars in the treatment of soft-tissue sarcomas and is the mainstay of treatment in patients with advanced or metastatic disease. Unlike other more common malignancies such as breast and colorectal cancer, the role of chemotherapy when used in the adjuvant setting in soft-tissue sarcomas is less well defined. Results from prior studies have been conflicting, in part due to the heterogeneity and rarity of the disease, and large-scale meta-analysis has been performed to address this issue...

This review focuses on optical coherence tomography (OCT)-based neurosurgical application for imaging and treatment of brain tumors. OCT has emerged as one of the most innovative and successful translational biomedical-diagnostic techniques. It is a useful imaging tool for noninvasive, in vivo, in situ and real-time imaging in soft biological tissues, such as brain tumor imaging. OCT can detect the structure of biological tissue in a micrometer scale, and functional OCT has some clinical researches and applications, such as nerve fiber tracts and neurovascular imaging...

Osteoradionecrosis, a rare complication of radiation therapy, is a slow progression disease which affects the surrounding structures of spinal components. It essentially weakens the soft tissue and bony configuration and can cause nerve impingement or cord compression. We describe a patient who underwent radiotherapy for thyroid cancer and presented with cervical kyphosis with anterolisthesis of C3/C4 and C4/C5 some 32 years later. We explore the role of anterior and posterior fusion, as well as hyperbaric oxygen therapy in promoting healing...

BACKGROUND: In the LATITUDE trial, addition of abiraterone acetate plus prednisone to androgen deprivation therapy (ADT) improved overall survival compared with placebos plus ADT in patients with newly diagnosed, high-risk, metastatic castration-naive prostate cancer. Understanding the effects of treatments on patient-reported outcomes (PROs) and health-related quality of life (HRQOL) is important for treatment decisions; therefore we aimed to analyse the effects of ADT plus abiraterone acetate and prednisone versus ADT plus placebos on PROs and HRQOL in patients in the LATITUDE study...

OBJECTIVE: Interdisciplinary work including surgery and additive radiotherapy is often needed for the therapy of tumours. Beneath this, brachytherapy is an important part of the radiotherapy. It was first used over 100 years ago and is in regular use after the development of afterload technology in the early 1970s. Today it is often used in different tumour therapies, for example in soft tissue sarcoma or breast tumours, in order to decrease the risk of local recurrence. Concerning its benefits, higher doses could be used because of the localized effect with equivalent local control rate and less toxicity of treatment...

Ewing sarcoma is an aggressive cancer of bone and soft tissue in children with poor prognosis. It is characterized by the chromosomal translocation between EWS and an Ets family transcription factor, most commonly FLI-1. EWS-FLI-1 fusion accounts for 85% of Ewing sarcoma cases. EWS-FLI-1 regulates the expression of a number of genes important for sarcomagenesis, can transform NIH3T3 and C3H10T1/2 cells, and is necessary for proliferation and tumorigenicity of Ewing sarcoma cells, suggesting that EWS-FLI-1 is the causative oncoprotein...

Prostate-specific membrane antigen (PSMA) is a transmembrane glycoprotein that is overexpressed in prostate cancer. Radiolabeled small molecules that bind with high affinity to its active extracellular center have emerged as a potential new diagnostic standard of reference for prostate cancer, resulting in images with extraordinary tumor-to-background contrast. Currently, gallium 68 (68Ga)-PSMA-11 (or HBED-PSMA) is the most widely used radiotracer for PSMA positron emission tomography (PET)/computed tomography (CT) or PSMA PET/magnetic resonance (MR) imaging...

Cytocompatible polysaccharide-based functional scaffolds are potential extracellular matrix candidates for soft and hard tissue engineering. This paper describes a facile approach to design cytocompatible, non-toxic, and multifunctional chitosan-cellulose based hydrogel beads utilising polysaccharide dissolution in sodium hydroxide-urea-water solvent system and coagulation under three different acidic conditions, namely 2 M acetic acid, 2 M hydrochloric acid, and 2 M sulfuric acid. The effect of coagulating medium on the final chemical composition of the hydrogel beads is investigated by spectroscopic techniques (ATR-FTIR, Raman, NMR), and elemental analysis...

Peter Y Yu, Denis C Guttridge
Rhabdomyosarcoma is a mesenchymal malignancy associated with the skeletal muscle lineage and is also the most common pediatric soft tissue cancer. Between the two pediatric subtypes, embryonal and alveolar rhabdomyosarcoma, the alveolar subtype is generally more aggressive and high-risk. Despite intensive multimodal therapy, patients with high-risk rhabdomyosarcoma continue to have poor prognosis. In this chapter we address the mechanisms underlying the dysregulation of myogenesis in rhabdomyosarcoma. We specifically focus on recently identified signaling pathways that function to inhibit myogenesis and how similar functions have been shown to overlap in rhabdomyosarcoma, potentially contributing to the disease...

There is an ongoing need for additional interventions in idiopathic pulmonary fibrosis (IPF) as antifibrotic drugs currently available only inhibit and do not stall disease progression. Vitamin K is a co-factor for the activation of coagulation factors. However, it is also required to activate proteins with functions outside of the coagulation cascade, such as matrix Gla protein (MGP), a defender against soft tissue calcification. Vitamin K antagonists are anticoagulants that are, for unknown reasons, associated with increased mortality in IPF...

Treatment of head and neck cancer (HNC) is accompanied by a high rate of morbidity, and complications can have a lifelong, profound impact on both patients and caregivers. Radiation-related injury to the hard and soft tissue of the head and neck can significantly decrease patients' quality of life. The purpose of this study is to provide patent-specific guidelines for managing the oral health and related side effects of HNC patients treated with radiation therapy. Based on reviewed articles retrieved on the PubMed database, guidelines for management of the oral health of this patient population were organized into three separate categories: cancer, patient, and dentition...

INTRODUCTION: Surgery is an essential component of a functional health system, with surgical conditions accounting for nearly 11-15% of world disability. While communicable diseases continue to burden low- and low-middle-income countries, non-communicable diseases, such as cancer, are an important cause of morbidity and mortality worldwide. Preliminary data on malignancies in low- and middle-income countries, specifically in Africa, suggest a higher mortality compared to other regions of the world, a difference partially explained by limited availability of screening and early detection systems as well as poorer access to treatment...

Endobronchial metastasis occurs in only 2%-5% of non-pulmonary cancers. Here we report on an 84-year-old woman who presented with breathlessness and light-headedness while on holiday in Australia, 2 years post-treatment for endometrial cancer. Initial CT pulmonary angiogram identified a soft tissue mass in the left hemithorax. A chest radiograph performed after repatriation was consistent with a large left pleural effusion, but bedside ultrasound showed a lobulated mass involving the left hemidiaphragm. A pleural procedure in the traditional 'triangle of safety' would have resulted in inadvertent puncture of the underlying mass...

BACKGROUND: As alveolar soft part sarcomas (ASPS) are rare with no prospective series within pediatric sarcoma trials, the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) examined the clinical data and outcomes of ASPS enrolled in a multinational study of nonrhabdomyosarcoma soft tissue sarcomas (NRSTS). PATIENTS AND METHODS: Twenty-two patients with ASPS were enrolled into the EpSSG NRSTS 2005 study. After surgical resection, subsequent treatment depended on the stratification of patients for completeness of resection and Intergroup Rhabdomyosarcoma Study (IRS) stage, size, and French Federation of Cancer Centres Sarcoma Group (FNCLCC) grade...

Integrated PET/MRI is a hybrid imaging technique enabling clinicians to acquire diagnostic images for tumor assessment and treatment monitoring with both high soft tissue contrast and added metabolic information. Integrated PET/MRI has shown to be valuable in the clinical setting and has many promising future applications. The protocol presented here will provide step-by-step instructions for the acquisition of whole-body 2-deoxy-2-(18F)fluoro-D-glucose (18F-FDG) PET/MRI data in children with cancer. It also provides instructions on how to combine a whole-body staging scan with a local tumor scan for evaluation of the primary tumor...

Cancer is the second most frequent cause of death in children. Because the prognosis for childhood malignancies has improved, attention has now focused on long-term consequences of cancer treatment. The immediate effects of chemotherapy on soft tissues have been well described; however, there is less information about long-term effects of chemotherapy on the development of dental tissues. To test the association between the effect of chemotherapy on enamel development, we examined two groups of rats: one that had received an intraperitoneal dose of 200 mg/kg of irinotecan, whereas the other (control) group had received vehicle only...
