Radiotherapy Metastatic Prostate Cancer Cell Lines Treated with Gold Nanorods Modulate miRNA Signatures.

MicroRNA (miRNA) modulation has been identified as a promising strategy for improving the response of human prostate cancer (PCa) to radiotherapy (RT). Studies have shown that mimics or inhibitors of miRNAs could modulate the sensitivity of PCa cells to RT. In addition, pegylated gold nanoparticles have been studied as a therapeutic approach to treat PCa cells and/or vehicles for carrying miRNAs to the inside of cells.

Application of Gold Nanoparticles as Radiosensitizer for Metastatic Prostate Cancer Cell Lines.

More than 50% of all prostate cancer (PCa) patients are treated by radiotherapy (RT). Radioresistance and cancer recurrence are two consequences of the therapy and are related to dose heterogeneity and non-selectivity between normal and tumoral cells. Gold nanoparticles (AuNPs) could be used as potential radiosensitizers to overcome these therapeutic limitations of RT.

Results of Surgery in Lung Cancer - A Retrospective Study of a Single Center Experience.

Objectives: Surgery provides the best chance for cure in patients with non-small-cell lung cancer stage I or II, but only a small portion of all new cases diagnosed are eventually suitable for surgical resection. Our goal was to appraise the surgical outcomes including survival and progression rates in patientswith histological diagnosis of lung cancer.

Methods: Between 1st August 2012 and 30th June 2018, the patients with histological lung cancer diagnosis that underwent surgical resection with a curative intent at the department of Cardiothoracic Surgery of Centro Hospitalar Univer- sitário de São João were included.

C-Reactive Protein as Predictive Biomarker for Response to Chemoradiotherapy in Patients with Locally Advanced Rectal Cancer: A Retrospective Study.

The standard of care for the treatment of locally advanced rectal cancer is neoadjuvant chemoradiotherapy (nCRT) followed by surgery, but complete response rates are reduced. To find predictive biomarkers of response to therapy, we conducted a retrospective study evaluating blood biomarkers before nCRT. Hemoglobin (Hg), C-reactive protein (CRP), platelets, carcinoembryonic antigen, carbohydrate antigen 19.

Factors affecting survival after palliative radiotherapy in patients with lung cancer.

Background: Lung cancer is the most common cancer worldwide. It is estimated that 60% of patients with NSCLC at time of diagnosis have advanced disease. The aim of this study was to identify factors that play a major role in the survival of lung cancer patients treated with palliative radiotherapy.

Baseline anaemia increases locally advanced rectal cancer mortality in older patients undergoing preoperative chemoradiation.

Purpose: The median diagnosis age of rectal cancer (RC) is 70 years old. The standard of care for locally advanced RC (LARC) is preoperative chemoradiation (CRT) followed by surgery. Anaemia is a frequent condition in older patients but is not a pure consequence of ageing.
