Local treatment in oligometastasis from breast cancer: an overview.

Oligometastasic breast cancer (OMBC) consists of breast cancer patient with a limited number of systemic metastases (≤ 5), all of them candidates for local ablative treatment with the intention of achieving long-term control of the metastasis and, eventually, an increase in survival The first consensus for the management of patients with oligometastatic breast cancer (OMBC) was published in 2007, establishing that a more aggressive multidisciplinary strategy is recommended in order to increase the survival while maintaining a good quality of life. The current scientific evidence is based on observational studies, mainly retrospective, systematic reviews and meta-analyses, and only a randomized nonexclusive study of oligometastatic (OM) published. All trials with Stereotactic Body Radiation Therapy (SBRT) in OM cancer have shown excellent tolerance and good local control, although first trials on Lung SBRT did not prove so excellent tolerance and had some deaths due to bronchus irradiation and secondary hemoptysis.

Indium Tin Oxide-Free Inverted Organic Photovoltaics Using Laser-Induced Forward Transfer Silver Nanoparticle Embedded Metal Grids.

Laser-induced forward transfer (LIFT) printing has emerged as a valid digital printing technique capable of transferring and printing a wide range of electronic materials. In this paper, we present for the first time LIFT printing as a method to fabricate silver (Ag) nanoparticle (np) grids for the development of indium tin oxide (ITO)-free inverted PM6:Y6 nonfullerene acceptor organic photovoltaics (OPVs). Limitations of the direct use of LIFT-printed Ag np grids in inverted ITO-free OPVs are addressed through a Ag grid embedding process.

Adjuvant radiotherapy in malignant tumors of parotid. Experience of the Navarra Hospital Complex.

Background: The objective of the study was to review the outcome of patients with parotid cancer treated with postoperative radiotherapy at Complejo Hospitalario de Navarra in the last ten years.

Materials And Methods: We retrospectively reviewed patients treated with adjuvant radiotherapy between January 2008 and December 2018. We analyzed demographic data, histopathologic findings, local control (LC) and overall survival (OS).

Selective Laser Sintering of Laser Printed Ag Nanoparticle Micropatterns at High Repetition Rates.

The increasing development of flexible and printed electronics has fueled substantial advancements in selective laser sintering, which has been attracting interest over the past decade. Laser sintering of metal nanoparticle dispersions in particular (from low viscous inks to high viscous pastes) offers significant advantages with respect to more conventional thermal sintering or curing techniques. Apart from the obvious lateral selectivity, the use of short-pulsed and high repetition rate lasers minimizes the heat affected zone and offers unparalleled control over a digital process, enabling the processing of stacked and pre-structured layers on very sensitive polymeric substrates.

The EORTC QLQ-C15-PAL questionnaire: validation study for Spanish bone metastases patients.

Purpose: Quality of life (QL) is a key outcome for advanced disease cancer patients. The European Organization for Research and Treatment of Cancer (EORTC) has developed the QLQ-C15-PAL questionnaire, a short version of the QLQ-C30 for palliative care. The aim of the present study is to validate the QLQ-C15-PAL for use with Spanish patients with bone metastasis.

Sonochemical deposition of magnetite on silver nanocrystals.

Sonochemical irradiation of iron (II) acetate aqueous solution in presence of silver nanopowder resulted in deposition of magnetite nanoparticles on silver nanocrystals, and imparted them with magnetic properties. The Ag-Fe(3)O(4) nanocomposite is well attracted to a permanent magnet, and demonstrates superparamagnetic behavior typical of nanomaterials in a magnetic field. The characterization of the product by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HR TEM), energy-dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy (XPS) reveal the presence of two phases of the silver and the magnetite, but no chemical interaction between them has been found.

Hyperfractionated radiotherapy and concomitant cisplatin for locally advanced laryngeal and hypopharyngeal carcinomas: final results of a single institutional program.

ABSTRACT The purpose of this study was to achieve locoregional control of locally advanced laryngeal carcinoma, survival, and organ preservation using split hyperfractionated accelerated radiation therapy and cisplatin concomitantly. This study was a phase II trial of chemoradiotherapy with split hyperfractionated accelerated radiation therapy, 1.6 Gy per fraction given twice per day to a total dose of 64 to 67.
