PURPOSE The common use of nomograms in Low Dose Rate (LDR) permanent prostate brachytherapy (BT) allows to estimate the number of seeds required for an implant. Independent dosimetry verification is recommended for each clinical dosimetry in BT. Also, nomograms can be useful for dose calculation quality assurance and they could be adapted to High Dose Rate (HDR). This work sets nomograms for LD...

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...

Mesh brachytherapy is a special type of permanent implant: it uses low-energy radioactive seeds in an absorbable mesh that sutured onto the tumor bed immediately after surgical resection. This treatment offers low additional risk to patient as implant procedure carried out part resection surgery. utilizes identification through direct visual evaluation during surgery or medical imaging followin...

Multicatheter brachytherapy can be applied as a monotherapy or in combination with external beam radiotherapy as an adjuvant treatment for soft tissue sarcoma. Successful application of brachytherapy in the treatment of soft tissue sarcoma requires implementation of multiple imaging modalities during preoperative and postoperative planning. Preoperative imaging is essential in planning local th...

Purpose. To assess the effectiveness of Ir-192 interstitial brachytherapy as an adjunct to wide local excision as a functionsaving strategy for soft tissue sarcomas.Subjects and methods. From September 1993 to April 1998, 20 consecutive patients diagnosed with soft tissue sarcomas were treated with a combination of wide local excision and interstitial brachytherapy. In 16 patients brachytherapy...

PurposePermanent breast seed implant (PBSI) brachytherapy is a novel technique for early-stage cancer. Computed tomography (CT) images are used treatment planning and freehand 2D ultrasound guidance. The multimodality imaging approach leads to discrepancies in target identification. To address this, prototype 3D (3DUS) system was recently developed PBSI. In this study, we characterize the 3DUS ...

PURPOSE Three-dimensional (3D) printing technology allows physicians to rapidly create customized devices for patients. We report our initial clinical experience using this technology to create custom applicators for vaginal brachytherapy. MATERIAL AND METHODS Three brachytherapy patients with unique clinical needs were identified as likely to benefit from a customized vaginal applicator. Pat...

Brachytherapy is a therapeutic modality that may provide a significant improvement in the therapeutic ratio when appropriately applied, and hence, is an appealing treatment strategy for the head and neck. For several tumor sites in the head and neck, the use of a brachytherapy implant has been demonstrated to be effective and is optimally provided within a multidisciplinary team setting. This e...
