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. PMID: 31435432 [PubMed]

AbstractPurpose of reviewMedical decisions concerning active surveillance are complex, especially when evidence on superiority of one of the treatments is lacking. Decision aids have been developed to facilitate shared decision-making on whether to pursue an active surveillance strategy. However, it is unclear how these decision aids are designed and which outcomes are considered relevant. The purpose of this study is to systematically review all decision aids in the field of oncological active surveillance strategies and outcomes used by authors to assess their efficacy.Recent findingsA search was performed in Embase, Med...

Abstract We aimed to estimate the risk of secondary cancer after radiotherapy (RT) in high-risk prostate cancer (HRPC) patients with pelvic irradiation. Computed tomography data of five biopsy-proven HRPC patients were selected for this study. Two different planning target volumes (PTV1 and PTV2 ) were contoured for each patient. The PTV1 included the prostate, seminal vesicles, and pelvic lymphatics, while the PTV2 included only the prostate and seminal vesicles. The prescribed dose was 54 Gy for the PTV1 with a sequential boost (24 Gy for the PTV2 ). Intensity-modulated RT (IMRT) and volumetric modulat...

warth D Abstract MR-guided radiotherapy requires novel QA methods for IMRT treatment plans (TPs). Here, an optimized method for TPs for a 1.5 T MR-linac was developed and implemented clinically. A static solid phantom and an MR-compatible 2D ionization chamber array were used. The array's response with respect to the incident beam gantry angles was characterized for four different orientations of the array relative to the beam. A lookup table was created identifying the optimum orientation for each gantry angle. For the QA of clinical MR-linac TPs, beams were grouped according to their gantry angles and measured w...

ConclusionsThis series is the largest to report that simultaneous curative-intent management of synchronous PC and RC is feasible and safe. Pelvic exenteration might be a better option when RC complete resection seems not achievable through TME.

ew D. Beggs Radiotherapy is routinely used as a neoadjuvant, adjuvant or palliative treatment in various cancers. There is significant variation in clinical response to radiotherapy with or without traditional chemotherapy. Patients with a good response to radiotherapy demonstrate better clinical outcomes universally across different cancers. The PI3K/AKT/mTOR pathway upregulation has been linked to radiotherapy resistance. We reviewed the current literature exploring the role of inhibiting targets along this pathway, in enhancing radiotherapy response. We identified several studies using in vitro cancer cell lines, in...

Authors: Konat-Bąska K, Chicheł A, Staszek-Szewczyk U, Maciejczyk A, Matkowski R Abstract Purpose: Prostate and colorectal cancers are the first and the third most popular malignancies in male population, in which some patients may develop these tumors metachronously or synchronously. At present, there are no standard recommendations, and oncologists need to provide an optimal management for two different cancers with an acceptable risk of possible treatment of adverse effects. Material and methods: This case report presents the treatment of a 61-year-old patient suffering from synchronous prostate and rectal...

ConclusionUSPIO-enhanced MRI of the pelvis at 7-T is technically feasible and offers opportunities for detecting USPIO uptake in normal-sized LNs, due to its high intrinsic signal-to-noise ratio and spatial resolution.Key Points• USPIO-enhanced MRI at 7-T can indicate USPIO uptake in lymph nodes based on computed TE images.• Our method promises a high spatial resolution for pelvic lymph node imaging.
