Comparación de mamografía digital 3D con mamografía 2D digital indirecta CR en detección de cáncer mamario

Objetivos Comparación retrospectiva en performance entre mamografía digital directa 3D/ tomosíntesis y mamografía 2D digital indirecta con CR, en detección del cáncer de mama. Material y Método Pacientes asintomáticos y sintomáticos estudiados con mamografía digital directa 3D/tomosíntesis entre agosto 2015 y junio 2016, se comparó con grupo de pacientes estudiados…

Later Outcomes and Alpha/Beta Estimate From Hypofractionated Conformal Three-Dimensional Radiotherapy Versus Standard Fractionation for Localized Prostate Cancer

Purpose Now that the follow-up time has exceeded 5 years, an estimate of the α/β ratio can be presented. The additional late outcomes in patients treated with three-dimensional conformal external beam radiotherapy for localized prostate cancer using a hypofractionated vs. a standard fractionation regimen are reported from this prospective nonrandomized…

Late Outcomes Following Hypofractionated Conformal Radiotherapy vs. Standard Fractionation for Localized Prostate Cancer: A Nonrandomized Contemporary Comparison

Purpose To study retrospectively late complications and biochemical control in patients treated with three-dimensional conformal external-beam radiotherapy for localized prostate cancer administered using hypofractionation vs. a standard fractionation regimen. The hypofractionation regimen (Hypo) was designed to avoid more late rectal reactions and to be done in half as many treatment…

Acute Toxicity After Hypofractionated Conformal Radiotherapy for Localized Prostate Cancer: Nonrandomized Contemporary Comparison With Standard Fractionation

Purpose To prospectively study acute rectal and urinary reactions from three-dimensional conformal external beam radiotherapy for localized prostate cancer comparing two hypofractionation regimens with standard fractionation (standard). The hypofractionation regimens were designed to avoid more late reactions in the hypofractionation groups than in the standard group, with the advantage of…

Acute radiation reactions in oral and pharyngeal mucosa: tolerable levels in altered fractionation schedules

Abstract Purpose To investigate whether a predictive estimate can be obtained for a ‘tolerance level’ of acute oral and pharyngeal mucosal reactions in patients receiving head and neck radiotherapy, using an objective set of dose and time data. Materials and methods Several dozen radiotherapy schedules for treating head and neck cancer have been…

Treatment of Breast Abscesses with Sonographically Guided Aspiration, Irrigation, and Instillation of Antibiotics

ABASTRACT OBJECTIVE We studied the feasibility of treating breast abscesses with sonographically guided aspiration, irrigation, and local instillation of antibiotics without placing indwelling catheters. MATERIALS AND METHODS Seventy-three patients with breast abscesses were seen from 1995 to 2001. Aspiration and irrigation were performed under sonographic guidance. Repeated aspiration was performed…
