PURPOSE The aim of this study was to determine the value of CA 19-9 in therapy monitoring and follow-up of locally advanced pancreatic cancer treated by radiochemotherapy. MATERIALS AND METHODS Ninety-five patients with locally advanced irresectable adenocarcinoma of the pancreas were treated with hyperfractionated accelerated radiotherapy, with 44.8 Gy(More)
Gliomatosis cerebri is defined as a remarkably diffuse glioma, characterized by widespread infiltration of the central nervous system. Clinicopathologic characteristics and imaging findings have been published but valid classification remains controversial. Few reports exist regarding therapeutic options in gliomatosis cerebri. Here we review data on 17(More)
PURPOSE/OBJECTIVE Biology and appropriate management of gastrointestinal (GI lymphomas are matters of an ongoing controversial debate. To evaluate histological features, sites of involvement and management of primary GI-lymphomas, a prospective multicentric study was initiated in 10/1992. Aim of study was the further standardization of operative and(More)
PURPOSE To determine the predictive value of carbohydrate antigen (CA) 19-9 in pancreatic cancer treated with radiochemotherapy. METHODS AND MATERIALS Ninety-five patients with locally advanced unresectable adenocarcinoma of the pancreas were treated with hyperfractionated accelerated radiotherapy to a total dose of 44.8 Gy combined with 5-fluorouracil(More)
BACKGROUND The ability of radiofrequency energy to extend across scar tissue is unknown. We investigated the effects of radiofrequency catheter ablation on intramural temperature in experimental chronic myocardial infarction. METHODS AND RESULTS Myocardial infarction was induced in eight dogs by a transcatheter coronary artery occlusion-reperfusion(More)
PURPOSE To quantify nonrespiratory organ motion in the pancreatic region and its effect on clinical target volume. MATERIALS AND METHODS Three-dimensional translations of the geometric centers of the volumes of interest--pancreatic head, body, and tail; left and right kidney; and the superior mesenteric artery--were measured in 20 patients by analyzing(More)
A variety of solutions are used to match tangential fields and opposed lymph node fields in irradiation of nodal positive breast cancer. The choice is depending on the technical equipment which is available and the clinical situation. The CT simulation of a non-monoisocentric technique was evaluated in terms of accuracy and reproducibility. Patients,(More)
PURPOSE This study examines the value of squamous cell cancer (SCC) antigen in patients irradiated for locally advanced cancer of the head and neck. MATERIALS AND METHODS In 20 patients (group A) treated with radiochemotherapy and in 20 patients (group B) receiving postoperative irradiation serum SCC values were investigated. RESULTS The pretreatment(More)
There are only three prior reports of abnormal thyroid function tests in patients who have received salsalate, the salicylate ester of salicylic acid. The authors report an elderly clinically euthyroid man who had thyroid function tests suggestive of central hypothyroidism while taking salsalate but whose thyroid tests returned to normal after the drug was(More)
Detection of free abdominal air requires in most cases immediate surgical intervention. However, there may be situations, where invasive procedures are not indicated. We present a case of asymptomatic pneumatosis intestinalis and free abdominal air in a patient with Aids. Pneumatosis intestinalis is a rare entity with accumulation of subserosal or(More)
