Purpose Intermediate-risk rhabdomyosarcoma (RMS) includes patients with either nonmetastatic, unresected embryonal RMS (ERMS) with an unfavorable primary site or nonmetastatic alveolar RMS (ARMS). The primary aim of this study was to improve the outcome of patients with intermediate-risk RMS by substituting vincristine and irinotecan (VI) for half of vincristine, dactinomycin, and cyclophosphamide (VAC) courses. All patients received a lower dose of cyclophosphamide and earlier radiation therapy than in pre...
Glioblastoma (GBM) is the most common and aggressive primary brain tumor resulting in high rates of morbidity and mortality. A strategy to increase the efficacy of available drugs and enhance the delivery of chemotherapeutics through the blood brain barrier (BBB) is desperately needed. We investigated the potential of Cisplatin conjugated gold nanoparticles (GNP-UP-Cis) in combination with MR-guided Focused Ultrasound (MRgFUS) to intensify GBM treatment. Viability assays demonstrated that GNP-UP-Cis greatly...
The use of computer simulation is arguably more widespread in other industries than in medicine. However, it has filtered into mainstream use in radiation therapy via a commercial product born from collaborative research partnership based in a radiation therapy department .The benefits and potentials of simulation training is discussed in this editorial from the perspective of an experienced radiation therapy physicist.
The combination of lomustine and bevacizumab is a commonly used salvage treatment for recurrent glioblastoma (GBM). We investigated the toxicity and efficacy of lomustine plus bevacizumab (lom-bev) in a community-based patient cohort and made a comparison to another frequently used combination therapy consisting of irinotecan plus bevacizumab (iri-bev). Seventy patients with recurrent GBM were treated with lomustine 90 mg/m2 every 6 weeks and bevacizumab 10 mg/kg every 2 weeks. Toxicity was registered and...
Pediatric patients with parameningeal rhabdomyosarcoma and high-risk features are recommended to receive radiotherapy at initiation of protocol therapy due to concerns about the increased risk of local and leptomeningeal failure from treatment delay. We report our early experience on a multi-institutional prospective trial incorporating delayed primary site radiation and reduced dose cyclophosphamide in all patients with parameningeal tumors. We observed an excessive number of locoregional treatment failure...
Radiation therapy has been a cornerstone of cancer management for many decades and is an integral part of the multi-modality care of patients with brain tumors. The known serious side effects of radiation therapy on the head or central nervous system are uncommon and include radiation necrosis, microangiopathy, and progressive leukencephalopathy. In addition, there have been descriptions of radiation-induced tumors including sarcomas, gliomas, lymphomas, and carcinomas of the thyroid. Patients who have rece...
Post-operative radiation therapy for brain metastases (BM) has become standard treatment. Concerns regarding the deleterious cognitive effects of Whole Brain Radiation Therapy spurred a trend to use focal therapies such as stereotactic radiosurgery (SRS). The purpose of this study was to prospectively evaluate the neuropsychological effects following post-resection SRS treatment since limited data exist in this context.
The analysis of biological and mesoscopic structures properties by diffusion MRI (dMRI) in brain after radiation therapy remains challenging. In our study, we described the consequences associated with an unwanted dose to healthy tissue, assessing radiation-induced brain alterations of living rats with dMRI compared to histopathology and behavioral assays.
Phase II study of neoadjuvant therapy with docetaxel, cisplatin, panitumumab, and radiation therapy followed by surgery in patients with locally advanced adenocarcinoma of the distal esophagus (ACOSOG Z4051).
The modern treatment of locoregionally advanced disease often requires a multimodality combination approach. A number of chemotherapeutic agents can be combined with radiation, but the platinum agent cisplatin, a potent radiation sensitizer, is best studied in head and neck cancer. Newer agents such as cetuximab can be used in combination with radiation therapy for those patients who cannot tolerate cisplatin. For chemotherapy-naïve patients with metastatic head and neck cancer who demonstrate a good perfo...
Cisplatin has been used as a chemotherapeutic agent to treat many different cancers. A well-known side effect of cisplatin is nephrotoxicity, which is the primary dose-limiting toxicity. Hydration in conjunction with appropriate diuresis can decrease the incidence of nephrotoxicity.
This study evaluated the possibility of accelerated gadolinium accumulation in irradiated brain parenchyma where the blood-brain barrier was weakened.
Cisplatin-based chemotherapy may have neurotoxic effects within the central nervous system. The aims of this study were 1) to longitudinally investigate the impact of cisplatin-based chemotherapy on whole-brain networks in testicular cancer patients undergoing treatment and 2) to explore whether possible changes are related to decline in cognitive functioning.
The aim of this study was investigate whether histopathological changes in the neurogenic region correlate with appropriate cognitive impairment in the experimental model of radiation-induced brain injury.
To quantify radiation exposure of radiation therapy technologists (RTTs) in a proton treatment facility in comparison with a photon therapy facility, to inform and establish these specialized occupational safety guidelines.
In patients who have previously undergone maximum radiation for metastatic brain tumors, a progressive enhancing inflammatory reaction (PEIR) that represents either tumor recurrence or radiation necrosis, or a combination of both, can occur. Magnetic resonance-guided laser-induced thermal therapy (LITT) offers a minimally invasive treatment option for this problem.
Human papillomavirus (HPV) is an important etiological factor in oropharyngeal squamous cell carcinoma (SCC). Compared to HPV-negative tumors, HPV-positive oropharyngeal SCC has shown a better response to nonsurgical treatments. In this study, we determined the dose-modifying factors for HPV-positive tumors with single-dose irradiation, with or without low radiosensitizing doses of cisplatin. In vitro, we determined an increased radiosensitivity of HPV-positive SCC, which might be a consequence of HPV-induc...
Radiation therapy (RT) is an effective treatment for primary brain tumors and intracranial metastases, but can occasionally precede new enhancing lesions on imaging studies that are difficult to discern between a tumor recurrence (TR) or radiation necrosis (RN). There is a need to identify clinical presentation and imaging patterns that may obviate the need for invasive definitive biopsy.
The use of radiation is an essential part of both modern cancer diagnostic assessment and treatment. Next-generation imaging devices create 3D visualizations, allowing for better diagnoses and improved planning of precision treatment. This is particularly important for primary brain cancers such as diffuse intrinsic pontine glioma or the most common primary brain tumor, glioblastoma, because radiotherapy is often the only treatment modality that offers a significant improvement in survival and quality of li...
To revise the recommendation on the use of concurrent chemotherapy (CC) with palliative thoracic external beam radiation therapy (EBRT) made in the original 2011 American Society for Radiation Oncology guideline on palliative thoracic radiation for lung cancer.
As radiation therapy treatment grows more complex over time, treatment delivery has become more susceptible to adverse events and patient safety risks from use error. The radiation therapy monitoring and treatment delivery user interface explored in this study was redesigned using ecological interface design, a human factors engineering method, and evaluated to improve treatment safety.
Over the past 20 years, PET/CT has had many technological and developmental advancements for patient care. PET/CT has evolved from solely used as a diagnosis and staging tool to now having an impact on treating cancer through a collaboration with radiation oncology. There are multiple considerations when integrating PET/CT into radiation therapy planning such as PET/CT center needs, the types of scans to offer, workflow considerations between the two centers, PET/CT center growth and demand on schedules, an...
Stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT) are effective treatments for management of brain metastases. Prospective trials comparing the 2 modalities in patients with fewer than 4 brain metastases demonstrate that overall survival (OS) is similar. Intracranial failure is more common after SRS, while WBRT is associated with neurocognitive decline. As technology has advanced, fewer technical obstacles remain for treating patients with 4 or more brain metastases with SRS, but leve...
To compare outcomes in patients receiving neoadjuvant stereotactic body radiation therapy (SBRT) with those receiving intensity-modulated radiation therapy (IMRT) for pancreatic adenocarcinoma.
