Context: In absence of prospective randomized trials determining the optimal management of localized prostate cancer remains undefined. Objective: To develop and disseminate an update on outcome of different treatment modalities, recommendations and guidelines of transperineal prostate brachytherapy. Evidence acquisition: In the past decade, the average number of brachytherapy patients per cent...

BACKGROUND Low-dose rate brachytherapy is a well established treatment modality of oral cancer. Data about high-dose rate (HDR) brachytherapy are still sparse with various fractionation schedules and heterogeneous results. AIM The aim of our retrospective study was to evaluate the results of HDR brachytherapy with doses of 3 Gy twice daily. PATIENTS AND METHODS Twenty patients with squamous...

The purpose of this study was to evaluate the efficacy and safety of high-dose-rate (HDR) brachytherapy of a single implant with two fractions plus external beam radiotherapy (EBRT) for hormone-naïve prostate cancer in comparison with radical prostatectomy. Of 150 patients with localized prostate cancer (T1c-T2c), 59 underwent HDR brachytherapy plus EBRT, and 91 received radical prostatectomy. ...

OBJECTIVES To determine the spectrum of pathophysiology underlying the lower urinary tract symptoms (LUTS) persisting for > or = 6 months after brachytherapy for localized prostate cancer. PATIENTS AND METHODS A database of men from two practice settings was searched for men who developed LUTS persisting for > or = 6 months after completing brachytherapy for localized prostate cancer. Patient...

High dose rate (HDR) endobronchial brachytherapy is a palliative treatment for symptomatic airway obstruction by malignant tumours. We report a novel use of HDR brachytherapy for treating non-malignant bronchial obstruction. The patient had a metal stent placed in a reconstructed airway after a bronchial tear to ensure patency. Granulation tissue formation in and around the stent caused symptom...

OBJECTIVES Brachytherapy is increasingly used as a treatment for localized prostate cancer but information regarding long-term, postimplantation, patient-reported sexual health-related quality-of-life (HRQOL) is scant. Neoadjuvant hormonal therapy is commonly administered with brachytherapy, yet its potentially adverse effects on subsequent sexual health have not been described using a validate...

Breast conserving surgery (BCS) with postoperative radiotherapy has been a standard treatment of early stage breast cancer for the last 30 years. Interstitial brachytherapy has been used as a boost therapy after whole breast external beam radiotherapy (EBRT), and recently, it's been investigated in selected patients as a possible technique of a single radiotherapy modality (partial breast irrad...

Interstitial brachytherapy represents the treatment of choice for small tumours, regionally localized in the oral cavity and the oropharynx. In the technical setting, continuous low-dose-rate (LDR) brachytherapy represented for many years the gold standard for administering radiation in head and neck brachytherapy. Large series of head and neck cancer patients treated with LDR brachytherapy hav...

BACKGROUND We evaluated whether detection of prostate-specific antigen (PSA) and human kallikrein 2 (hK2) transcripts in the peripheral blood during brachytherapy could predict biochemical outcome. METHODS Eighty-one patients who underwent (125)Iodine-based brachytherapy for localized prostate cancer (Gleason score <8, PSA <20 ng/ml, stage <T3), participated in the study. Brachytherapy was gi...
