Additional prospective data are needed, and toxicities should be correlated with reRT course and composite dose constraints. Recommended reRT composite dose constraints in 2 Gy equivalent dose are: esophagus V60 <40% and DMax <100-110 Gy, lung V20 <40%, heart V40 <50%, aorta/great vessels DMax <120 Gy, trachea and proximal bronchial tree DMax <110 Gy, spinal cord DMax <57 Gy, and brachial plexus DMax <85 Gy.Ĭonclusions: For the first time, consensus dose constraints for thoracic reRT are recommended to minimize the risks of high-grade and potentially fatal toxicities from repeat radiotherapy. Stereotactic body radiation therapy (SBRT) can provide increased conformality and dose escalation and is optimal for primary-alone failures, but caution is needed for central reRT with SBRT. Particle therapy may further reduce toxicities and/or enable safer reRT dose escalation compared with 3DCRT and IMRT.
For conventionally fractionated reRT, intensity-modulated radiation therapy (IMRT) is recommended over 3D conformal radiation therapy (3DCRT) to increase dose conformality. Limited data exist regarding the use of hyperfractionation and low- or high-dose rate reRT for NSCLC. Acute esophagitis and pneumonitis and late pulmonary, cardiac/great vessel, esophageal, brachial plexus and spinal toxicities are dose limiting for reRT. There are no data to guide the use of concurrent targeted therapy or immunotherapy with reRT, and this is not recommended outside of a clinical trial. The available data suggest potential benefit in clinical outcomes with concurrent chemoradiation for reRT, but the decision should be based on patient performance status, tolerance to prior systemic therapy and other individual patient/tumor characteristics. Composite dose constraints were also recommended. Of 236 articles, 49 remained after exclusions (3 prospective) and formed the basis for these recommendations on: 1) the role of concurrent chemotherapy with reRT, 2) factors associated with toxicity from reRT and 3) what reRT modalities, dose-fractionation schemas and dose rates should be used. Methods: A PRISMA systematic review assessed all studies published through 3/2019 evaluating toxicities, local control and/or overall survival for NSCLC thoracic reRT.
Objectives: This ARS-ACR Appropriate Use Criteria Systematic Review and Guidelines on Reirradiation for NSCLC provides direct guidance on the safety and efficacy of reRT and recommends consensus dose constraints for thoracic reRT to minimize risks of high grade toxicities. To date, no systematic review on the safety and efficacy of reRT for NSCLC exists, and no dedicated guidelines are available. Thoracic reRT, however, is particularly challenging due to its considerable risk and the current lack of standardized approaches, guidelines and dose constraints. Pierre and Marie Curie made history not only in that respect, but also because their scientific teamwork led to the discovery of radioactivity and two new. This was hardly a sufficient manner to shed light upon one of the most ghastly real life horror stories of American industry.Background: Reirradiation (reRT) for locoregional recurrences can provide durable control and improved symptoms and progression-free survival for select NSCLC patients.
#AMERICAN RADIUM ABSTRACT SUBMISSION DEADLINE MOVIE#
And as such, I am rating the movie a mediocre five out of ten stars.
I was disappointed with the contents of this 2018 movie as it came to an end. "Radium Girls" was gifted with a rather good ensemble of actors and actresses, and while they had precious little to work with in terms of a proper script and dialogue, then the actors and actresses did manage to put on good enough performances, enough so to make the movie watchable. Sure, the movie was watchable, but it just felt too shallow and bland, to be bluntly honest. The pacing of the storyline felt, oddly enough, monotonous and never really managed to capture me entirely. This movie's story holds such a significant tale and importance that it felt that directors Lydia Dean Pilcher and Ginny Mohler just nonchalantly brushed over the topic without delving properly into the contents and putting to the screen the tragedy and the horror of these real life events. This is indeed a very tragic story, but for some reason directors Lydia Dean Pilcher and Ginny Mohler managed to deliver the storyline and its contents in a somewhat disappointing manner, and I must say that I was left with an overwhelming sensation of "was that really it?". Why? Well, because of the subject and topic of the storyline and its importance in real life and the lives of those girls working in the Radium business. I must admit that I was expecting much more from the 2018 movie titled "Radium Girls" than what writers Ginny Mohler and Brittany Shaw managed to deliver.
