BACKGROUND Positron emission tomography (PET) has a potential improvement for staging and radiation treatment planning of various tumor sites. We analyzed the use of 18F-fluorodeoxyglucose (FDG)-PET/computed tomography (CT) images for staging and target volume delineation of patients with head and neck carcinoma candidates for radiotherapy. METHODS(More)
PURPOSE The management of patients with cervical lymph-node metastases from unknown primary site (UPS) remains a matter of discussion. This study aimed to analyze the results and prognostic factors in a series of patients treated with radiotherapy. METHODS AND MATERIALS Data from 113 patients who presented with cervical lymph nodes metastases from UPS(More)
To analyse the role of MR diffusion-tensor imaging (DTI) and perfusion-weighted imaging (PWI) in characterising tumour boundaries in patients with glioblastoma multiforme. Seventeen patients with surgically treated WHO IV grade gliomas who were candidates for adjuvant chemo-radiotherapy were enrolled. Before (T0) and after radiation treatment (T1), they(More)
Mucosal melanoma of the head and neck is a rare, poor prognosis tumour with a high tendency to recur locally and regionally after surgical resection. A number of centres have used radiotherapy to sterilize positive and close margins after non-radical surgery or to treat inoperable cases. The present article discusses the literature data to analyze the(More)
BACKGROUND The reproducibility of patient setup for radiotherapy is based on various methods including external markers, X-rays with planar or computerized image acquisition, and, more recently, surface matching imaging. We analyzed the setup reproducibility of 16 patients affected by prostate cancer who underwent conformal radiotherapy with curative intent(More)
BACKGROUND A variety of hypofractionated radiotherapy schedules has been proposed after breast conserving surgery in the attempt to shorten the overall treatment time. The aim of the present study is to assess acute and late toxicity of using daily fractionation of 2.25 Gy to a total dose of 45 Gy to the whole breast in a mono-institutional series. (More)
AIMS AND BACKGROUND Rectal and urinary toxicities are the principal limiting factors in delivering a high target dose to patients affected by prostate cancer. The verification of such toxicity is an important step before starting a dose-escalation program. The present observational study reports on the acute and late rectal and urinary toxicity in relation(More)
PURPOSE To analyze the feasibility of intraoperative radiotherapy (IORT) in patients with high-risk prostate cancer and candidates for radical prostatectomy. METHODS AND MATERIALS A total of 38 patients with locally advanced prostate cancer were enrolled. No patients had evidence of lymph node or distant metastases, probability of organ-confined disease(More)
Treatment of locally advanced prostate cancer is still a challenge. Combined treatments including hormone therapy, radiotherapy, and/or surgery can achieve less than 50% of disease free survival at 10 years. Almost 50% of patients with locally advanced disease after radical prostatectomy experience local relapse and biochemical failure occurs up to 70% of(More)
Malignant paraganglioma of the glomus vagale is a rare tumor entity originating from paraganglia or glomus cells. It typically affects middle age. It differs from benign paraganglioma because of its rapid growth and more aggressive clinical behavior. We report the case of a 40-year-old man presenting with a 5 cm lesion in the upper right cervical region(More)
