Tubular carcinoma of the breast: Outcome and loco-regional recurrence in 307 patients

2005

Abstract Purpose The aim of this study is to describe the University of Florence experience in evaluating clinical, pathologic and treatment factors as they are related to the outcome and loco-regional recurrence in patients with tubular breast carcinoma. Material and methods Three hundred and seven patients (median age 56.4 years, range 26–91 years) with histological verified tubular carcinoma of the breast were consecutively treated at University of Florence from 1976 to 2001. All patients were followed for a median of 8.4 years (range 3 months to 20 years). Thirty-seven women underwent mastectomy and 270 underwent breast conserving surgery. Positive axillary nodes were found in 15% of pa…

Dental implants rehabilitation in a patient with head and neck radiotherapy for osteosarcoma in the jaw. A clinical case report

2021

A 52-year-old female patient with a diagnostic of osteosarcoma in the mandible, in which it was necessary a reconstruction with a microvascularized osteomyocutaneous fibula bone. Coadjuvant chemotherapy was scheduled. Two years later, 4 osseointegrated implants (OII) were placed in the fibula a 2 OII in the right mandible, using a splint guided surgery. The final prosthodontic consisted in a metal ceramic restoration using CAD/ CAM technology. Key words:Oral rehabilitation, oral cancer, head and neck radiotherapy, oral oncology.

FMECA Application in Tomotherapy: Comparison between Classic and Fuzzy Methodologies

2022

Accident analysis in radiotherapy highlighted the need to increase quality assurance (QA) programs by the identification of failures/errors with very low probability (rare event) but very severe consequences. In this field, a Failure Mode, Effects and Criticality Analysis (FMECA) technique, used in various industrial processes to rank critical events, has been met with much interest. The literature describes different FMECA methods; however, it is necessary to understand if these tools are incisive and effective in the healthcare sector. In this work, comparisons of FMECA methodologies in the risk assessment of patients undergoing treatments performed with helical tomotherapy are reported. …

Manejo de schwannoma vestibular con radiaciones : experiencia del IVO

2013

A partir de la década de los 70, nace la radiocirugía (RC) como tratamiento alternativo a la cirugía convencional en el tratamiento de los schwannomas vestibulares(SV). Poco a poco dicha técnica, ha ido desbancando a la microcirugía alcanzando cifras del 58 % de tratamientos de RC frente a la cirugía convencional. En el presente estudio analizamos el resultado de 167 tumores tratados con radiaciones (bien con dosis única (RC) o con dosis fraccionada, RT Estereotáctica Fraccionada (RTEF), determinando el control local y las complicaciones como tratamiento del SV. Analizamos los resultados en función de la tecnología utilizada para tratarlos, bien colimadores cilíndricos o bien micromutilámin…

Vocal function exercises and vocal hygiene combined treatment approach as a method of improving voice quality in irradiated patients for laryngeal ca…

2018

Introduction: Despite the negative effects of radiation therapy on voice quality is well documented in literature few studies have focused on the efficacy of voice therapy in the irradiated laryngeal cancers population. The purpose of this study was to investigate the efficacy of an evidence-based voice therapy, known as Vocal Function Exercises (VFE) in a combined approach with Vocal Hygiene (VH) in improving vocal function in patients who have been irradiated for laryngeal cancers and compared to the results of VH alone treatment. Materials and methods: A prospective, randomized and controlled study involved patients with primary laryngeal cancer treated with curatively intended radiother…
