Consideraciones radiológicas del cáncer de pulmón y Covid-19: una mirada oncológica
Radiological considerations of lung cancer and Covid-19: a oncology look

Patients with SARS-Cov-2 infection and lung cancer have an unfavorable prognosis, characterized by higher rates of respiratory failure, use of invasive mechanical ventilation and higher mortality rates. Due to similarities in affected organs in Covid-19 and lung cancer, the radiological accurate diagnosi...

Radiation therapy with elective lymph node irradiation for breast cancer: dosimetric study and impact on cardiovascular risk and second neoplasms

SUMMARY OBJECTIVE: The aim of this study was to perform dosimetric analysis of radiotherapy (RT) plans with or without elective nodal irradiation (ENI) and estimate whether the increase in mean doses (MDs) in the heart and lungs with ENI may lead to late side effects that may surpass the benefits of tr...

Effect of tumor and normal lung volumes on the lung volume-dose parameters of IMRT in non-small-cell lung cancer

Clinics; 76 (), 2021
OBJECTIVES: To explore the effect of tumor and normal lung volumes on lung volume-dose parameters in patients with non-small-cell lung cancer (NSCLC) who had undergone intensity-modulated radiation therapy (IMRT). METHODS: The clinical data of 208 patients with NSCLC who underwent radical IMRT between J...

miR-183 promotes radioresistance of lung adenocarcinoma H1299 cells via epithelial-mesenchymal transition

Braz. j. med. biol. res; 54 (5), 2021
Lung adenocarcinomas are usually sensitive to radiation therapy, but some develop resistance. Radiation resistance can lead to poor patient prognosis. Studies have shown that lung adenocarcinoma cells (H1299 cells) can develop radioresistance through epithelial-mesenchymal transition (EMT), and this proc...

Cáncer de pulmón diagnosticado mediante ecoendoscopia transesofágica y biopsia por punción con aguja fina
Lung cancer diagnosed by transesophageal ecoendoscopy and fine needle aspiration biopsy

Medicina (B.Aires); 80 (2), 2020
El cáncer de pulmón es la principal causa de muerte por cáncer en todo el mundo. Los nódulos pulmonares ubicados en proximidad al mediastino, retrocardíacos, cercanos a grandes vasos o por delante de la columna vertebral pueden resultar de difícil acceso por vía percutánea o broncoscópica. La pu...

Identification of the targets of hematoporphyrin derivative in lung adenocarcinoma using integrated network analysis

Biol. Res; 52 (), 2019
BACKGROUND: Hematoporphyrin derivative (HPD) has a sensibilization effect in lung adenocarcinoma. This study was conducted to identify the target genes of HPD in lung adenocarcinoma. METHODS: RNA sequencing was performed using the lung adenocarcinoma cell line A549 after no treatment or treatment with X-...

Emerging radiotherapy technology in a developing country: A single Brazilian institution assessment of stereotactic body radiotherapy application

Summary Objective: To provide a quantitative profile of the indications and use of stereotactic body radiotherapy (SBRT) in a developing country oncology-based institution. In addition, to describe the patients' and treatment characteristics, and to provide a temporal analysis. Method: SBRT patients tr...

Resultados del tratamiento inductivo en el cáncer de pulmón de células no pequeñas localmente avanzado
Results of the inductive treatment of locally advanced non-small cell lung cancer

Rev. cuba. cir; 46 (3), 2007
Se evaluaron 44 pacientes con cáncer de pulmón de células no pequeñas localmente avanzado que recibieron radioquimioterapia basada en platino para la inducción de la cirugía. Nueve pacientes (20,5 por ciento) tuvieron respuestas radiológicas completas y en 17 pacientes (38,6 por ciento) se logró ...
