Investigation of inter‐source and intra‐source spectral variations in an electronic brachytherapy source using spectral measurements and Monte Carlo simulations

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background The Xoft electronic brachytherapy source is commonly used to treat superficial lesions and tumors located at shallow depths. However, uncertainties in material composition and geometry, mainly arising due to the manual assembly of the x‐ray tube components, contribute to inter‐source variability in the tube output spectrum.

HDR brachytherapy for anal cancer.

Journal of gastrointestinal oncology, 2014
The challenge of treating anal cancer is to preserve the anal sphincter function while giving high doses to the tumor and sparing the organ at risk. For that reason there has been a shift from radical surgical treatment with colostomy to conservative treatment.

Case reports that high-dose-rate brachytherapy using custom-designed mouthpiece mold for early-stage squamous cell carcinoma of the hard palate is useful

Radiation Oncology
Background Surgery is the primary therapy for hard palate cancer, but this sometime worsens oral function and unavailable for patients with several comorbidities. Radiotherapy represents an alternative curative treatment option to preserve oral function,

Interstitial HDR brachytherapy (HDR-BT) in early stage mobile tongue cancers in young patients – Gliwice experience

Journal of Contemporary Brachytherapy, 2010
Purpose: In early stage mobile tongue cancer radical radiotherapy offers good local control and organ preservation, which is especially important in the group of young patients. In our department, for many years HDR-BT has been performed in mobile tongue

Alterations of Sexual and Erectile Functions after Brachytherapy for Prostate Cancer Based on Patient-Reported Questionnaires

Prostate Cancer
The aim of the study was to compare the side effects of high-dose-rate brachytherapy (HDRBT) and low-dose-rate brachytherapy (LDRBT), with a particular focus on the effects on sexual functions and sexual well-being (PROMOBRA study, NCT02258087 ...

The Influence of Au, Gd and I Nanoparticles on Radiation Dose Absorption during High Dose Rate Brachytherapy with 192Ir Source

Brazilian Journal of Radiation Sciences
The efficacy of high dose rate (HDR) brachytherapy for cervical cancer is often constrained by the high radiation exposure to the healthy tissues that surround the tumor consequently diminishing the therapeutic benefits of the technique.

MRS-guided HDR brachytherapy boost to the dominant intraprostatic lesion in high risk localised prostate cancer

BMC Cancer, 2010
Background It is known that the vast majority of prostate cancers are multifocal. However radical radiotherapy historically treats the whole gland rather than individual cancer foci.

Clinical and dosimetric correlation in terms of treatment response, bladder and rectal toxicities in cervical cancer patients treated with cobalt 60 high dose rate brachytherapy [PDF]

PeerJ
Background High dose rate (HDR) image-guided brachytherapy with Cobalt-60 isotope is a relatively recent approach. The aim of the study is to evaluate the clinical and dosimetric parameters in terms of tumour response, bladder, and rectal toxicity in ...
