Evaluate the toxicity and efficacy of adjuvant temozolomide (TMZ) and irinotecan (CPT-11) for 12 months following concurrent chemo-radiation in newly diagnosed glioblastoma (GBM).
Glioblastoma is the most common and aggressive primitive brain tumor in adults. Temozolomide (TMZ) administered daily with radiation therapy, followed by adjuvant TMZ has become the standard treatment. Although TMZ treatment has been considered to have a low toxicity profile, studies have noted the development of a severe myelosuppression, especially during the concomitant treatment; this toxicity may in some cases be prolonged and consequently treatment must be definitively discontinued. We analyzed two ca...
Radiation therapy and concomitant temozolomide chemotherapy are commonly used in treatment of brain tumors, but they may also result in behavioral impairments such as anxiety and cognitive deficit. The present study sought to investigate the effect of fluoxetine on the behavioral impairments caused by radiation and temozolomide treatment. C57BL/6J mice were subjected to a single cranial radiation followed by 6-week cyclic temozolomide administration, and then treated with chronic administration of fluoxetin...
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...
To update our experience with long-term outcomes in patients with desmoid fibromatosis treated with radiation therapy (RT) and to characterize factors associated with increased risk of local recurrence.
To study the prognostic value of neutrophil disorders in a retrospective cohort of high-grade glioma patients receiving definitive concurrent temozolomide and radiation.
We aimed to determine dose-volume constraints that correlate with severe (grade ≥3) radiation pneumonitis (RP) in patients diagnosed with malignant pleural mesothelioma (MPM), treated using volumetric modulated arc therapy (VMAT).
Radiation is the standard therapy used for treating Glioblastoma (GBM), a grade IV brain cancer. Glioma Stem-like Cells (GSCs), an integral part of GBM enforces resistance to radiation therapy of GBM. Studying the differential biomolecular composition of GSCs with varying levels of radiation sensitivity can aid in identifying the molecules and their associated pathways which impose resistance to cells thereby unraveling new targets which would serve as potential adjuvant therapy. Raman spectroscopy being a ...
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...
The most common primary central nervous system tumor in adults is the glioblastoma multiforme (GBM). The highly invasive nature of GBM cells is a significant factor resulting in the inevitable tumor recurrence and poor patient prognosis. Tumor cells utilize structures known as invadopodia to faciliate their invasive phenotype. In this study, utilizing an array of techniques, including gelatin matrix degradation assays, we show that GBM cell lines can form functional gelatin matrix degrading invadopodia and ...
The aim of this study was to identify risk factors to predict a biochemical recurrence (BCR) in patients treated with salvage radiation therapy (SRT) after radical prostatectomy (RP).
In the setting of spinal metastases with epidural cord compression, radiosurgery is often only considered when there is sufficient separation between the epidural disease and the spinal cord. However, in patients who are non-surgical candidates or those who prefer non-operative management, there may be a benefit from stereotactic body radiation therapy (SBRT) even when the epidural target is closer than the traditionally referenced 3 mm distance from the spinal cord. The purpose of this retrospective study ...
Asian melanoma patients, predominantly comprised of acral and mucosal subtypes, might not benefit from immunotherapy and targeted therapy as much as Caucasian patients. Novel treatment strategies are demanded after conventional treatment failure. This was a prospective, single-arm, and single-center dose escalation study to investigate the safety and preliminary efficacy of apatinib combined with temozolomide in heavily treated advanced melanoma patients.
In patients with non-small cell lung cancer (NSCLC) who undergo trimodality therapy (chemoradiation followed by surgical resection), it is unknown whether limiting preoperative radiation dose to the uninvolved lung reduces postsurgical morbidity. This study evaluated whether radiation fall-off dose parameters to the contralateral lung that is unaffected by NSCLC are associated with postoperative complications in NSCLC patients treated with trimodality therapy.
Ipsilateral regional nodal status is an important independent prognostic factor for patients with breast cancer. Several decisions regarding local therapy are necessary for patients found to have pathologically involved lymph node(s). This article reviews the role of completion dissection and/or radiation therapy in patients found to have positive sentinel lymph node(s), taking into consideration use of mastectomy vs lumpectomy, tumor characteristics, tumor biology, plans for systemic therapy, and patient p...
With the increasing use of advanced radiation techniques such as intensity modulated radiation therapy, stereotactic radiation therapy, and proton therapy, radiation oncologists now have the tools to mitigate radiation-associated toxicities. This is of utmost importance in the treatment of a pediatric patient. To best utilize these advanced techniques to mitigate radiation-induced growth abnormalities, the radiation oncologist should be equipped with a nuanced understanding of the anatomy of centers of grow...
For patients treated with palliative radiation, we examined the association between life expectancy predictions by radiation oncologists and aggressive end-of-life care.
Radiation therapy might modify the cancer immune environment to enhance the antitumor effect of immune checkpoint inhibitors. We performed a feasibility study of nivolumab following stereotactic radiation therapy for chemotherapy pretreated advanced non-small-cell lung cancer.
Delayed autologous breast reconstruction is commonly recommended in patients requiring postmastectomy radiation. This study examines gross and histologic changes in the breast skin of patients who have undergone postmastectomy radiation to help determine when radiation-induced skin changes begin to stabilize.
Haemorrhage is a frequent complication of radiation cystitis leading to emergency presentations in patients with prior pelvic radiation therapy. Standard initial patient management strategies involve resuscitation, bladder washout with clot evacuation and continuous bladder irrigation. Beyond this, definitive surgical treatment is associated with significant morbidity and mortality. Alternative less invasive management options for non-emergent haemorrhagic cystitis include systemic medical therapies, hyperb...
Palbociclib is an oral cyclin-dependent kinase 4/6 inhibitor, which is efficacious in treating breast cancer. Currently, there are numerous active clinical trials testing palbociclib alone or in combination with other medications for treating various types of malignancies. Here, we evaluated the anti-cancer effect of palbociclib in combination with radiation therapy (RT) for treating human hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) and addressed the molecular mechanism behind the combinati...
Advances in multimodality imaging, providing accurate information of the irradiated target volume and the adjacent critical structures or organs at risk (OAR), has made significant improvements in delivery of the external beam radiation dose. Radiation therapy conventionally has used computed tomography (CT) imaging for treatment planning and dose delivery. However, magnetic resonance imaging (MRI) provides unique advantages: added contrast information that can improve segmentation of the areas of interest,...
Family physicians and internal medicine specialists play an essential role in treating cancer patients. Modern technological advances in radiotherapy are not widely appreciated by primary care physicians. Bone metastases are a frequent complication of cancer. Palliative radiation therapy, as a component of modern advances in radiation treatments, should not subject normal bodily structures to excessive doses of irradiation. The sacrum is a common destination site for bone metastases, yet its concave shape a...
