PURPOSE In the study we present the initial results of palliative treatment using combined methods of HDR-BT and stent insertion in patients with advanced esophagus cancer. MATERIAL AND METHODS Fifty patients were treated in the Great Poland Cancer Center using HDR-BT between June 2001 and December 2005 and they were enrolled into the study. All patients underwent endoscopic insertion of self...

The purpose of this study was to evaluate the applicator-guided volumetric-modulated arc therapy (AGVMAT) solution as an alternative to high-dose-rate brachytherapy (HDR-BRT) treatment of the vaginal vault in patients with gynecological cancer (GC). AGVMAT plans for 51 women were developed. The volumetric scans used for plans were obtained with an implanted CT-compatible vaginal cylinder which ...

BACKGROUND High-dose-rate (HDR) brachytherapy using the mold technique is a less invasive treatment for early lip and oral cavity cancer. However, limited reports exist regarding the feasibility of this method. In this retrospective study, we evaluated the outcome of this therapy and investigated its feasibility for lip and oral cavity tumors. METHODS Between May 2002 and December 2010, 17 pa...

PURPOSE To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. MATERIALS AND METHODS Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using (192)Ir between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment ...

AIM To evolve a fast dose verification method for high-dose-rate (HDR) brachytherapy treatment plans and to demonstrate its applicability in different clinical cases. MATERIALS AND METHODS We developed a software tool in VC++ for the Varisource HDR unit for HDR dosimetry plan verification using TG-43 parameters. HDR treatment dosimetry of a number clinical cases using Varisource was verified ...

PURPOSE The estimation of cosmetic effect in 93 patients with early breast cancer treated with breast conserving surgery (BCS) followed by combined radiotherapy, including HDR brachytherapy (HDR-BT) boost. MATERIAL AND METHODS After BCS (tumorectomy or quadrantectomy) external beam radiation therapy (EBRT) was used in total dose of 50 Gy for the whole breast. Tumor bed was localized basing on...

Objective: In locally advanced cervical cancer, the management consists of external beam radiotherapy and brachytherapy. The impact of intracavitary brachytherapy versus interstitial brachytherapy on local tumor control, survival and complications were prospectively investigated in this study. Methods: A total of 60 patients with stage IIB, IIIB cervical cancer were treated using a combination ...

This manuscript presents a case of early stage squamous cell carcinoma of the left buccal mucosa treated with intensity-modulated radiation therapy (IMRT) followed by a high-dose rate (HDR) brachytherapy boost. With limited literature available on HDR mold (stent) radiotherapy for oral cancer, a discussion on the issues encountered during treatment planning and delivery may prove to be insightf...

Background/Aim: To compare five radiotherapy methods for prostate cancer. Patients and Methods: During 2005-2018, the data of patients with non-metastatic cancer were retrospectively analysed. treated high-dose-rate brachytherapy (HDR-BT); low-dose-rate (LDR-BT); or external-beam (EBRT), including conventionally fractionated (CFRT), moderate-hypofractionated (MHRT), ultra-hypofractionated (UHRT...

Brachytherapy plays an important role in the definitive treatment of cervical cancers by radiotherapy. In the present study, we investigated whether sliding-window intensity-modulated radiation therapy (IMRT) can achieve a pear-shaped distribution with a similar sharp dose falloff identical to that of brachytherapy. The computed tomography scans of a tandem and ovoid patient were pushed to both...
