BACKGROUND: Metastatic cancers occur when cancer cells break away from the primary tumour. One of the most common sites of metastasis is the bone, with several therapeutic options currently available for managing bone metastases. In a resource-constrained environment, policy makers and practitioners need to know which options are cost effective. OBJECTIVE: The aim of this systematic review was to review and appraise published economic evaluations on treatments for the management of bone metastases...

Background: Management of brain metastases typically includes radiotherapy (RT) with conventional fractionation and/or stereotactic radiosurgery (SRS). However, optimal indications and practice patterns for SRS remain unclear. We sought to evaluate national practice patterns for patients with metastatic disease receiving brain RT. Methods: We queried the National Cancer Data Base (NCDB) for patients diagnosed with metastatic non-small cell lung cancer, breast cancer, colorectal cancer, or melanoma from 2004 to 2014 who received upfront brain RT...

PURPOSE: Radiation oncologists are responsible for deciding which day-to-day variations are acceptable or not in the treatment setup. However, properly qualified and trained radiation therapists might be capable to perform image registration. We evaluated in our centre the capability and accuracy of radiation therapists to validate positioning images in a prospective study. METHODS AND PATIENTS: A total of 84 patients treated for prostate, head and neck, lung or breast cancer was prospectively and randomly included from July 2011 to July 2013 in radiotherapy unit of our institution...

Mixed breast cancer, especially of uncommon breast cancer histotypes, is rare, limiting our understanding of the disease and influencing diagnostic and management outcomes. We report a case of mixed breast cancer, with features of intraductal and solid papillary and tubular carcinomas, which appeared in a young patient. Physical examination, ultrasonography, molybdenum target mammography, and histopathology were performed for a definitive diagnosis. Tumor resection followed by radiotherapy and adjuvant chemotherapy was selected as the therapeutic strategy, and the patient was followed up thrice post treatment...

Standard electron treatments are nowadays still performed using standard or molded patient-specific cut-outs placed in the electron applicator. Replacing cut-outs and electron applicators with the photon multileaf collimator (pMLC) for electron beam collimation would make standard electron treatments more efficient and would facilitate advanced treatment techniques like modulated electron radiotherapy (MERT) and mixed beam radiotherapy (MBRT). In this work, a multiple source Monte Carlo beam model for pMLC shaped electron beams commissioned at a source to surface distance (SSD) of 70 cm is extended for SSDs up to 100 cm and validated for several Varian treatment units with field sizes typically used for standard electron treatments...

To evaluate feasibility, safety, toxicity profile and dosimetric results of volumetric modulated arc therapy (VMAT) to deliver regional nodal irradiation (RNI) after either mastectomy or breast conservation (BCS) in high-risk breast cancer patients. Between January 2015 and January 2017, a total of 45 patients were treated with VMAT to deliver RNI together with whole breast or post-mastectomy radiotherapy. The fractionation schedule comprised 50 Gy in 25 fractions given to supraclavicular and axillary apex nodes and to whole breast (after BCS) or chest wall (after mastectomy)...

Acquired radioresistance compromises the efficacy of radiotherapy for carcinomas including esophageal cancer (EC), thus resulting in recurrence and poor survival. Recent research corroborated radiosensitive function of simvastatin in stem-like breast cancer cells. However, its role in EC radioresistance remains poorly elucidated. Here, we developed a radioresistant EC cell line Ec9706-R with higher resistance to irradiation relative to control Ec9706 cells. Intriguingly, Ec9706-R cells exhibited epithelial-mesenchymal transition (EMT) characteristics with high invasion and migration ability...

As the use of breast reconstruction and postmastectomy radiotherapy (PMRT) has increased over the past decade, the typical approach to integrating radiotherapy with breast reconstruction has provoked intense controversy in the management of breast cancer. PMRT can lead to an increased frequency of complications in the reconstructed breast. Conversely, the reconstructed breast can increase the complexity of radiotherapy delivery. How to minimise the frequency of complications without compromising oncological or cosmetic outcomes of the reconstructed breast is an important shared multidisciplinary goal for oncologists and their patients...

PURPOSE: The potential benefits from respiratory gating (RG) compared to free-breathing (FB) regarding target coverage and dose to organs at risk for breast cancer patients receiving post-operative radiotherapy (RT) in the DBCG HYPO multicentre trial are reported. MATERIAL AND METHODS: Patients included in the DBCG HYPO trial were randomized between 50 Gy in 25 fractions (normofractionated) versus 40 Gy in 15 fractions (hypofractionated). A tangential forward field-in-field dose planning technique was used to cover the clinical target volume (CTV) with the intent to limit dose to the left anterior descending coronary artery (LADCA) to 20 Gy and 17 Gy in the normo- and hypofractionated arms, respectively...

BACKGROUND: Over the past 40 years the Danish Breast Cancer Cooperative Group (DBCG) has made significant contributions to improve outcome and to make treatment of patients with early breast cancer more tolerable through nationwide and international trials evaluating loco-regional and systemic treatments. These trials have been instrumental to establish standards for the treatment of early breast cancer. METHODS: The DBCG 82 trials had a global impact by documenting that the significant gain in loco-regional recurrence from postmastectomy radiation added to systemic therapy was associated with a reduction in distant recurrence and mortality in high-risk pre- and postmenopausal patients...

Breast cancer is the most common malignancy in women and a public health problem worldwide. Breast cancer is often accompanied by an inflammatory process characterized by the presence of proinflammatory cytokines such as tumor necrosis factor (TNF-α), which has important implications in the course of the disease. Inflammation has been described primarily as a favorable environment for tumor development. However, under certain conditions TNF-α can promote signals for activation, differentiation, survival or cell death, so the study of the variants of this cytokine, its receptors, the presence of polymorphisms and its implication in different phenotypes of breast cancer is necessary...

During the early decades of radiation therapy for breast cancer, local control of disease was documented consistently but, enigmatically, an anticipated impact on breast cancer survival was not observed, leading to confusion in our understanding of the natural history of breast cancer and radiation effects. Now, almost 90 years after its first use in breast cancer, technology developments in diagnostic imaging and radiation therapy have elucidated parts of this enigma. The data now available demonstrate a significant impact of radiation therapy on survival as well as disease control and treatment-related mortality, opening a doorway to understanding the powerful impact of radiation therapy on both breast cancer and critical organs...

Ductal carcinoma in situ (DCIS) is a heterogeneous disease that has been investigated less extensively than invasive breast cancer. Women with DCIS are mainly treated with conservative surgery almost exclusively followed by radiotherapy. However, as radiation treatment is not always effective, the search for biomarkers capable of identifying DCIS lesions that could progress to invasive cancer is ongoing. Although conventional biomarkers have been thoroughly studied in invasive tumours, little is known about the role played by androgen receptor (AR), widely expressed in DCIS...

Phyllodes tumors account for less than 1% of tumors of the mammary gland, have both epithelial and stromal components and are classified as benign, borderline and malignant. The malignant tumors are highly heterogeneous: they can differentiate to liposarcomas, fibrosarcomas, rhabdomyosarcomas, chondrosarcomas or osteosarcomas. The differentiation to osteosarcoma is extremely rare, constitutes 1.3% of cases and is very aggressive. The standard treatment of these tumors is surgical. The role of radiotherapy and chemotherapy is not clear...

Partial breast irradiation of early breast cancer patients after lumpectomy and the use of endogenous adipose tissue (AT) for breast reconstruction are promising applications to reduce the side effects of breast cancer therapy. This study tries to investigate the possible risks associated with these therapeutic approaches. It also examines the influence of adipose derived stem cells (ADSCs) as part of the breast cancer microenvironment, and endogenous AT on breast cancer cells following radiation therapy. ADSCs, isolated from human reduction mammoplasties of healthy female donors, exhibited multilineage capacity and specific surface markers...
