OBJECTIVE
Diffusion-weighted MRI is sensitive to molecular motion and has been applied to the diagnosis of stroke. Our intention was to investigate its usefulness in patients with brain tumor and, in particular, in the perilesional edema.
METHODS
We performed MRI of the brain, including
Irradiating glioblastoma preoperative edema (PE) remains controversial. We investigated the associations between tumors' PE extent with invasion into synchronous subventricular zone and corpus callosum (sSVZCC) and treatment outcomes to provide the clinical evidence for radiotherapy
OBJECTIVE
The production of prostaglandin (PG) within brain tumors probably generates excessive amounts of oxygen free radicals that may disrupt microvessel permeability within the tumor and in the adjacent brain. We evaluated the effect of systemic therapy with recombinant human
We sometimes experience patients with persistent or progressive arytenoid edema, among which residual or recurrent cancer is often accompanied. Because it is difficult to distinguish tumour rest or recurrence from normal tissue sequelae in the early period after irradiation, it is important to know
OBJECTIVE
To determine if physiologically based MRI sequences can be used to detect endolymphatic sac tumor (ELST)-associated hydrops, the authors performed contrast-enhanced delayed FLAIR imaging in consecutive ELST patients with clinical findings consistent with hydrops.
METHODS
Consecutive
The synchronous appearance of different inner ear pathologies with a nearly equivalent clinical manifestation such as Menière's disease and vestibular schwannoma is very rare but leads to a relevant dilemma concerning therapy options. MRI is the method of choice to detect intralabyrinthine tumors.
Cerebral edema commonly accompanies brain tumors and frequently leads to lethal intracranial compartmental shifts and elevated intracranial pressure. Therapeutic modalities for tumor-associated cerebral edema include diuretics, osmotherapy, and corticosteroids. Recently, hypertonic saline (HS) has
To study the effects of glucocorticoids and chemotherapeutic agents on the pathophysiology of the tumor-induced brain edema, the site of Evans blue-albumin extravasation, the distribution of extravasated serum albumin, and the extent of local astrocytic reaction were examined in a rat model of
BACKGROUND
Duguetia furfuracea (A. St. -Hil.) Saff. (Annonaceae) is commonly known in Brazil as "araticum-seco," and its root is used in folk medicine to treat inflammatory and painful disorders. However, no studies have been performed to evaluate these therapeutic activities.
OBJECTIVE
Investigate
MEK inhibitors are a group of drugs that have shown reliable effects in the treatment of metastatic melanoma and non-small-cell lung cancer. Peripheral edema is an adverse event associated with MEK inhibitors; however, there has been no systematic attempt to evaluate peripheral edema data observed
It is generally presumed that xeroderma pigmentosum (XP) patients are extremely sensitive to developing UV erythema, and that they have a more than 1000-fold increased skin cancer risk. Recently established mouse models for XP can be employed to investigate the mechanism of these increased
The detection of brain tumors using standard techniques of qualitative, relaxation-weighted magnetic resonance imaging (MRI) requires the application of contrast agents. We investigated whether or not it is possible to use diffusion-weighted MRI to localize tumors without contrast enhancement. Three
OBJECTIVE
We report our study on two patients to highlight the risk of underdosage of the clinical target volume (CTV) due to edema during high-dose-rate interstitial brachytherapy (HDR-ISBT) of mobile tongue cancer.
METHODS
To treat the lateral side of the CTV, flexible applicator tubes were
Tumor treatment fields (TTFields) are an approved adjuvant therapy for glioblastoma (GBM). The magnitude of applied electrical field has been shown to be related to the anti-tumoral response. However, peritumoral edema may result in shunting of electrical current around the tumor, BACKGROUND
Tumor-to-tumor metastasis is a rare, but well-reported, curiosity in which one type of primary neoplasm metastasizes to another primary tumor type within the same person. Often there are limited clinical consequences and the condition is an incidental finding identified only on
