Impact of brachytherapy technique (2D versus 3D) on outcome following radiotherapy of cervical cancer.
Conclusions: In cervical cancer treatment, the use of a 3D brachytherapy technique (MRI-guided with or without interstitial needles) showed a trend towards an increased local control and improved overall survival with reduced toxicity, compared to the conventional 2D brachytherapy technique. The use of interstitial needles allowed dose sculpting, resulting in delivery of higher doses to the HR-CTV, while reducing radiation doses to organs at risk, such as the bladder.

Successful salvage treatment of refractory recurrence of maxillary sinus carcinoma using image-guided high-dose-rate interstitial brachytherapy.
Authors: Zhang Y, Wu N, Zhao Z, Chen Q, Cheng G
Abstract
This case report illustrates a treatment effect of image-guided high-dose-rate (HDR) interstitial brachytherapy for refractory recurrence of maxillary sinus carcinoma. A 61-year-old male was previously admitted to another hospital and received surgery because of left maxillary sinus squamous cell carcinoma (SCC) 6 years ago. Tumor regrowth was noted 2 years after the initial radical surgery. The patient accepted local excision again for the recurrence, followed by external beam radiotherapy. Despite salvage treatment with surgery and external irradiation, th...

High-dose-rate brachytherapy in treatment of non-melanoma skin cancer of head and neck region: preliminary results of a prospective single institution study.
Conclusions: With appropriate patient selection and choosing as lowest dose per fraction as possible, HDR brachytherapy with customized surface molds yields good oncological and cosmetic results for the treatment of localized skin BCC and SCC.

Quality assurance during interstitial brachytherapy: in vivo dosimetry using MOSFET dosimeters.
Conclusions: The deviations between planned and measured dose values were markedly influenced by the proximity of the detector to the PTV because where the edema exerts, the greatest influence on the tube applicator geometry. The positioning of the patient during irradiation must correspond to the positioning in the planning CT. Further studies are needed to investigate the role of in vivo dosimetry during interstitial brachytherapy as a routine procedure.

High-dose-rate brachytherapy in severe trismus: Making it happen!
We present a report on the management of a previously-irradiated completely edentulous patient with severe trismus for whom high-dose-rate surface mould brachytherapy had been prescribed. A unique, reliable, and practical solution has been presented based firmly on the scientific knowledge of contemporary implant dentistry.

Effectiveness and safety of a robot-assisted 3D personalized template in 125I seed brachytherapy of thoracoabdominal tumors.
Conclusions: Through analysis of the selected patients with thoracoabdominal tumors, the robot-assisted 3D personalized template in 125I seed brachytherapy was a more effective and safer method. It can achieve a more favorable OS and LC.

Comparison of impact of target delineation of computed tomography- and magnetic resonance imaging-guided brachytherapy on dose distribution in cervical cancer.
Conclusions: A combination of MRI and CT is a safe alternative approach for cervical cancer HDR brachytherapy. The technique provides comparable dosimetric outcomes to MRI-based planning, while being more cost-effective.

End-to-end test for computed tomography-based high-dose-rate brachytherapy.
Conclusions: The end-to-end test presented allows a practice-oriented realization for checking the whole treatment chain for HDR afterloading technique and CT-imaging. The presented phantom seems feasible for performing periodic system checks as well as to verify newly introduced brachytherapy techniques with sufficient accuracy.

Brachytherapy for localized prostate cancer in the modern era: a comparison of patient-reported quality of life outcomes among different techniques.
Conclusions: Patients receiving HDR brachytherapy had lower acute urinary and rectal toxicity compared to the patients receiving LDR, even when combined with EBRT. However, long-term toxicity was similar.

Treatment of locally advanced cervical cancer in a patient with a bicornuate uterus with MRI-guided intracavitary/interstitial brachytherapy.
Conclusions: We found that the use of the hybrid applicator allowed for adequate target coverage in a patient with unusual anatomy. The patient tolerated treatment well and demonstrated favorable response on follow-up exam and imaging. The long-term curative result needs to be further evaluated.

Image-guided high-dose-rate brachytherapy for prostate cancer patients with previous rectal resection and pelvic irradiation: feasibility study.
Conclusions: Fluoroscopy and 3D CT image-guided interstitial brachytherapy is feasible and appears to be a suitable treatment technique for patients with clinically localized prostate cancer after previous rectal resection and external beam radiation therapy.

Single institution implementation of permanent 131Cs interstitial brachytherapy for previously irradiated patients with resectable recurrent head and neck carcinoma.
Conclusions: Cesium-131 interstitial brachytherapy is feasible and does not pose major radiation safety concerns; it should be considered as a treatment option for previously irradiated patients with recurrent, resectable HNC.

Carotid dosimetry after re-irradiation with 131Cs permanent implant brachytherapy in recurrent, resected head and neck cancer.
Conclusions: Carotid artery doses from 131Cs are reported. Vascularized tissue flaps should be considered when planning 131Cs brachytherapy.

Dosimetric comparison of graphical optimization and inverse planning simulated annealing for brachytherapy of cervical cancer.
Conclusions: In 3D brachytherapy of cervical cancer, GO and IPSA optimizations do not present a significant difference in target dose coverage; nevertheless, IPSA may reduce the maximum dose to normal tissue when compared with GO.

Evaluation of deformable image registration algorithm for determination of accumulated dose for brachytherapy of cervical cancer patients.
Conclusions: The hybrid-based DIR algorithm demonstrated low registration uncertainty for both contour matching and dose mapping. The DA difference between DIR-based and SS approaches was statistically significant for both bladder and rectum and hybrid-based DIR showed potential to assess DA between brachytherapy fractions.
