Effectiveness of two different HDR brachytherapy regimens with the same BED value in cervical cancer.
CONCLUSIONS: Doses and BEDs at different bladder, rectal and lymphatic trapezoid points, local control, and complications in both HDR ICBT groups did not have statistically significant differences (p > 0.05). Both HDR ICBT schedules are well tolerable and equally effective.

Electromagnetic tracking for treatment verification in interstitial brachytherapy.
Authors: Bert C, Kellermeier M, Tanderup K
Abstract
Electromagnetic tracking (EMT) is used in several medical fields to determine the position and orientation of dedicated sensors, e.g., attached to surgical tools. Recently, EMT has been introduced to brachytherapy for implant reconstruction and error detection. The manuscript briefly summarizes the main issues of EMT and error detection in brachytherapy. The potential and complementarity of EMT as treatment verification technology will be discussed in relation to in vivo dosimetry and imaging.

Rectal separation using hydroxypropyl methylcellulose in intracavitary brachytherapy of cervical cancer: an innovative approach.
CONCLUSIONS: Hydrogel instillation is a useful tool for recto-vaginal separation during cervical cancer brachytherapy. It increases therapeutic ratio without any adverse event.

The impact of body mass index on dosimetric quality in low-dose-rate prostate brachytherapy.
CONCLUSIONS: In this study we show that BMI is a significant pre-implant predictor of D90 (< 140 Gy vs. ≥ 140 Gy). Although other studies have reported that prostate volume also affects D90, our study did not find this correlation to be statistically significant, likely because all of our patients had a prostate volume < 50 cc. Our study suggests that in patients with higher BMI values, more rigorous peri-implant dosimetric parameters may need to be applied in order to achieve a target D90 > 140 Gy.

Evaluation of interpolation methods for TG-43 dosimetric parameters based on comparison with Monte Carlo data for high-energy brachytherapy sources.
CONCLUSIONS: The radial mesh studied was adequate for interpolating gL(r) for high-energy brachytherapy sources, and was similar to commonly found examples in the published literature. For F(r,θ) close to the source longitudinal-axis, polar angle step sizes of 1°-2° were sufficient to provide 2% accuracy for all sources.

Surgery combined with brachytherapy in patients with retroperitoneal sarcomas.
CONCLUSIONS: Combined treatment (surgery and brachytherapy) was possible to be carried out on 68% of RS patients. The overall number of complications was quite high, however acceptable, taking into consideration the application of extensive, multi-organ treatments in case of sarcoma recurrences in this localization. The results suggest that the method of treatment will improve the final outcome when most of patients will be qualified for treatment of primary sarcomas in experienced centre.

HDR and LDR Brachytherapy in the Treatment of Lip Cancer: the Experience of the Catalan Institute of Oncology.
CONCLUSIONS: Our findings confirm that brachytherapy is an effective treatment for lip cancer. The results from our series are in line with those published elsewhere. Based on our limited data, HDR appears to be equally as good as LDR, although this needs to be confirmed by further studies.

HDR endobronchial brachytherapy in palliative and combined radical treatment of lung cancer.
Authors: Fijuth J
Abstract
In patients with advanced or metastatic lung cancer who present predominantly with dyspnoea and haemoptysis the use of HDR brachytherapy has been proven an effective method of palliation. The application of brachytherapy as a boost to EBRT in curative cases is much more restricted. It can be considered in a selected group of patients with dominating endobronchial disease, who are medically inoperable, or have small or occult carcinomas of the lung.

Salvage brachytherapy for local recurrences of prostate cancer treated previously with radiotherapy.
CONCLUSIONS: Salvage brachytherapy for localized prostate cancer (3 × 10 Gy every 14 days) seems to be a safe and well tolerated procedure. A significant decline in prostate-specific antigen (PSA) level is seen in patients with hormone-responsive cancer. Long-term efficiency and toxicity of the procedure are yet to be established.

Comparative cost-effectiveness of focal and total salvage (125)I brachytherapy for recurrent prostate cancer after primary radiotherapy.
CONCLUSIONS: Focal salvage (125)I brachytherapy dominates TS, as it has lower treatment costs and leads to less toxicity in our center. Larger comparative studies with longer follow-up are necessary to assess the exact influence on (biochemical disease free) survival and toxicity.

Treatment planning for multicatheter interstitial brachytherapy of breast cancer - from Paris system to anatomy-based inverse planning.
Authors: Major T, Polgár C
Abstract
In the last decades, treatment planning for multicatheter interstitial breast brachytherapy has evolved considerably from fluoroscopy-based 2D to anatomy-based 3D planning. To plan the right positions of the catheters, ultrasound or computed tomography (CT) imaging can be used, but the treatment plan is always based on postimplant CT images. With CT imaging, the 3D target volume can be defined more precisely and delineation of the organs at risk volumes is also possible. Consequently, parameters calculated from dose-volume histogram can be used for quantitative plan evaluation. ...

Staged reconstruction brachytherapy has lower overall cost in recurrent soft-tissue sarcoma.
CONCLUSIONS: In recurrent STS, SR has a longer initial hospital stay when compared to IR. At 18 months, SR had lower rates of LF, translating to lower total costs for the patient. SR is the more cost-effective brachytherapy approach in the treatment of STS, and should be considered as healthcare transitions into value-based medicine.

High biologically effective dose radiation therapy using brachytherapy in combination with external beam radiotherapy for high-risk prostate cancer.
CONCLUSIONS: High-dose (BED ≥ 220 Gy) radiotherapy by LDR in combination with EBRT has shown an excellent outcome on BFFS in high-risk and very high-risk cancer, although causal relationship between BED and BFFS remain to be explained further.
