Increasing the efficiency of the retinoblastoma brachytherapy protocol with ultrasonic hyperthermia and gold nanoparticles: A rabbit model.
This study purposed to evaluate the efficacy of brachytherapy with the modality of ultrasonic hyperthermia in the presence of gold nanoparticles (GNPs) on an ocular retinoblastoma tumor in an animal model of the rabbit. MATERIALS AND METHODS: Gold nanoparticles (GNPs) were synthesized and confirmed by UV-vis spectroscopy, scanning electron microscopy and dynamic light scattering. Rabbit eyes were exposed to an ultrasonic continuous mode to reach 42 °C, and then turned into a pulse mode (40%) to maintain in the hyperthermia range (42-45 °C) for 30 min. For in vivo experiments, a retinoblasto...

Current Status of Anatomical Magnetic Resonance Imaging in Brachytherapy and External Beam Radiotherapy Planning and Delivery
Radiotherapy planning and delivery have dramatically improved in recent times. Imaging is key to a successful three-dimensional and increasingly four-dimensional based pathway with computed tomography embedded as the backbone modality. Computed tomography has significant limitations for many tumour sites where soft-tissue discrimination is suboptimal, and where magnetic resonance imaging (MRI) has largely superseded in the diagnostic arena. MRI is increasingly used together with computed tomography in the radiotherapy planning pathway and is now established as a prerequisite for several tumours. (Source: Clinical Oncology)

Accelerated Partial Breast Irradiation (APBI): Where Are We Now?
AbstractPurpose of ReviewAccelerated partial breast irradiation (APBI) is an alternative approach to breast conserving therapy (BCT) where radiation (RT) is delivered over a shorter period of time compared with whole breast irradiation (WBI), resulting in improved patient convenience and cost savings. APBI can be delivered using brachytherapy, intraoperative RT, or conformal external beam radiation therapy (EBRT) techniques. In this review, the authors appraise the latest modern randomized controlled trials (RCTs) of APBI and discuss the application of the data to clinical practice.Recent FindingsThe OCOG-RAPID and NSABP B...

Salvage low dose rate brachytherapy for prostate cancer recurrence following definitive external beam radiation therapy
Intraprostatic local failure following primary external beam radiation therapy (RT) for prostate cancer remains a challenging clinical scenario. While multiple local therapy options have been proposed, no treatment has emerged as standard owing largely to concerns regarding increased toxicity and poor outcomes [1 –5]. As a result, many are unfortunately relegated to life-long androgen deprivation therapy (ADT), which is exclusively palliative in nature and itself bears substantial morbidity [6–8].

Adapting to ensure brachytherapy remains a vital component of our future
For more than a century, brachytherapy has been a vital component of cancer treatment. Unfortunately, in recent years, this valuable technique has seen a notable decline in utilization. Competing treatment modalities and lack of robust training are in part to blame, leaving in-training and early career radiation oncologists unequipped to perform and retain the skills required to execute a variety of complicated brachytherapy procedures. To increase physician confidence with and subsequently mitigate underuse of this important modality, innovative educational methodologies are more essential than ever. (Source: Brachytherapy)

We wished to investigate the outcome of surgery combined with external-beam radiotherapy (EBRT) or brachytherapy (125I seeds) for the treatment of primary adenoid cystic carcinoma (ACC) of the oral and maxillofacial region.

Standard radiotherapy in the EBRT group was 60 Gy. A treatment-planning system was used to create implantation plans with a prescribed dose of 60–120 Gy and 125I seeds were implanted postoperatively.

ICRU-BP dose should be monitored during treatment planning alongside volumetric parameters. Frequency seems associated with larger irradiated volumes.

Accuracy of dwell-position detection with a combined electromagnetic tracking brachytherapy system for treatment verification in pelvic brachytherapy
High dose-rate (HDR) brachytherapy (BT) is commonly used to treat prostate and cervical cancer by irradiating the target volume using dedicated applicators and/or catheters. BT offers sharp dose gradients which may lead to decreased dose to organs at risk compared to external beam radiotherapy.[1,2] Image-guided implant reconstruction has become standard practice, using medical imaging such as CT, MR or ultrasound acquired before treatment planning.[3,4] After reconstructing the applicator and/or interstitial catheters, a treatment plan is created using the target and organ at risk delineations by optimizing dwell times in...

However, a randomized trial and large retrospective data question its safety after observing lower rates of survival than open surgery [1,2]. The causes of this higher recurrence rate are not definitely established but may result from cancer exposure to peritoneum during vaginal section and cancerous-cells spillage enhanced by pneumoperitoneum or uterine manipulator.

Urine in the lung: An uncommon cause of transudative pleural effusion.
Abstract Urinothorax [UT], the accumulation of urine in the pleural space, is an uncommon cause of pleural effusions resulting from trauma, obstruction, or iatrogenic causes.

PIVOTALboost: A phase III randomised controlled trial of prostate and pelvis versus prostate alone radiotherapy with or without prostate boost (CRUK/16/018).
Abstract •PIVOTALboost evaluates benefits/toxicity of pelvic node RT and focal boost dose escalation.•Unfavourable intermediate/high risk and bulky local disease are most likely to benefit.•Functional MRI imaging is used to select patients for different types of dose escalation.•HDR brachytherapy or focal dose escalation with IMRT are used as options.•Training and support is provided to reduce variations of contouring and radiotherapy planning.•The trial is recruiting patients in 38 radiotherapy centres through the UK.
