Ricke et  al. reported their findings on the efficacy and safety of selective internal radiation therapy (SIRT) with resin yttrium-90 (90Y) microspheres (SIR-Spheres®, Sirtex) in combination with sorafenib compared to sorafenib treatment alone. This clinical trial with a superiority design, also known as t he SORAMIC study, was performed in patients with intermediate to advanced hepatocellular carcinoma (HCC). No overall survival (OS) benefit was found when adding SIRT to sorafenib treatment. In the ‘intention-to-treat’ population, median OS was 12.1 months in the SIRT plus sorafenib group vs.

The addition of androgen deprivation therapy (ADT) to radiotherapy (RT) is the standard of care for prostate cancer patients with unfavourable intermediate risk (UIR) and high-risk disease. In this population, ADT has been shown to improve oncological outcomes by increasing RT local effect [1 –3] and likely by reducing the micrometastatic burden. Although the role of ADT in high-risk prostate cancer patients is firmly established, the benefit associated with this therapy in UIR patients treated with dose-escalated RT is less well defined [4,5].

Radiation therapy remains an essential component of cancer therapy for millions of patients annually in the United States and globally. Radiation therapy involves the focal deposition of ionizing radiation (IR) to the tumor and surrounding at-risk tissue compartments such as regional lymph nodes. The most common treatment approaches include external beam radiation therapy (EBRT) using high-energy photons, electrons, or protons, as well as brachytherapy and radionuclide therapy. Significant technical advances in EBRT and diagnostic imaging over the past several decades have enabled more localized and precise dose deposition...

Alongside radical prostatectomy, radiation therapy is an effective treatment modality for prostate cancer patients irrespective of risk group. Nevertheless, a considerable number of these patients are faced with isolated local failure of prostate cancer after radiation therapy with curative intent. Up to 10% of patients with a low-risk, 10-20% with an intermediate-risk and up to 30-37% with high-risk tumors will suffer local recurrence during follow-up [1 –4]. Thus, the possibility of an effective local salvage therapy is of paramount importance for curative therapy of a prostate cancer recurrence.

Background: CyberKnife SBRT is capable of producing dosimetry comparable to that created by HDR brachytherapy. Our original CyberKnife prostate SBRT schedule of 3,800 cGy/4 fractions (“high dose”) was based upon favorable published prostate HDR brachytherapy experience. Subsequently, our trial was modified to allow a lower dose of 3,400 cGy/5 fractions (“moderate dose”) in selected cases.Methods: Two hundred eighty-nine low and intermediate-risk patients were treated to either high dose (178 pts) or moderate dose (111 pts). The dose selection was individualized; high dose more commonly used in young...

Abstract INTRODUCTION: Uveal melanoma is most commonly treated with radiotherapy, destroying the tumour cells with adequate safety margins and limiting collateral damage to surrounding structures to preserve maximal vision. We used optical coherence tomography (OCT) to study the effects of radiotherapy on the retina. METHODS: Patients with posteriorly located choroidal melanoma treated with proton beam radiotherapy (PBR) and ruthenium-106 brachytherapy between January 2010 and June 2014 underwent spectral domain OCT. RESULTS: Images of 32 patients following ruthenium-106 brachytherapy and 44 patients fol...

The Royal College of Physicians and Surgeons of Canada has established a diploma certification program in brachytherapy, with the goal of standardizing brachytherapy training and standards. The diploma may be obtained either by way of a training route or a Practice Eligibility Route. Training is undergone through a Royal College –accredited brachytherapy program, analogous to a residency program with clearly defined curriculum, objectives, and expectations. The trainee submits a portfolio demonstrating achievement of the various competencies required and typically takes 12 months to complete.

We report the results of the first 100 patients who have experienced radiotherapy treatment since the state of alarm (66 women and 34 men). In these patients, the FI is 12.12-lower than previous years. PMID: 32565905 [PubMed]
