Stereotactic body radiation therapy for lung metastases from colorectal cancer: outcomes and prognostic factors in a series of 109 patients.

Background: Stereotactic body radiotherapy (SBRT) has been applied in the treatment of inoperable lung metastases. We retrospectively evaluated local control (LC) and prognostic factors in patients treated with SBRT for colorectal cancer (CRC) pulmonary metastases.

Materials And Methods: Unicentric retrospective study of 109 patients with CRC lung metastases treated with SBRT between 2013 and 2020.

May-Thurner Syndrome: The Worst-Case Scenario.

May-Thurner syndrome (MTS) is caused by compression of the left common iliac vein by the right common iliac artery against the spinal column. It can range from asymptomatic or present with subtle and unspecific signs and symptoms and rarely exhibit severe complications such as pulmonary embolism (PE). The diagnosis is confirmed by typical imaging findings.

Neurological Spectrum of Epstein-Barr Virus Infection: A Rare Clinical Case.

The Epstein-Barr virus (EBV) is a DNA virus that has been infecting humans since ancient times, capable of causing a wide range of pathologies and affecting approximately 90% of the population. A 61-year-old male with no significant medical history presented with a 5-day history of imbalance and difficulty walking. Neurological examination revealed specific findings, including absent reflexes, bilateral asynergy, and gait abnormalities.

[Venous Thromboembolism in Pediatric Age: A 15 Year Retrospective Review].

Introduction: Pulmonary thromboembolism and deep venous thrombosis occur in pediatric age, with unknown incidence, morbidity and mortality. Our aim is to review the epidemiology, clinical presentation, complementary diagnostic tests and prognosis of patients with pulmonary thromboembolism and deep venous thrombosis.

Material And Methods: Retrospective, descriptive and analytical study of pediatric patients admitted to a Level II hospital for pulmonary thromboembolism and deep venous thrombosis, between 2000 and 2014.

In vivo dosimetry using Gafchromic films during pelvic intraoperative electron radiation therapy (IOERT).

Objective: To characterize in vivo dose distributions during pelvic intraoperative electron radiation therapy (IOERT) for rectal cancer and to assess the alterations introduced by irregular irradiation surfaces in the presence of bevelled applicators.

Methods: In vivo measurements were performed with Gafchromic films during 32 IOERT procedures. 1 film per procedure was used for the first 20 procedures.
