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)
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)
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 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)
BACKGROUND 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. (More)
UNLABELLED In locally advanced carcinoma of the exocrine pancreas combined radiochemotherapy has been established as a standard treatment. MATERIALS AND METHODS Two different treatment schemes have been consecutively used. Between 1/1994 and 12/2001, a total of 110 patients with locally advanced adenocarcinoma of the pancreas were treated with(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)
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 To evaluate the functional effects of ionizing radiation in patients with unresectable pancreatic cancer in the early period after accelerated radiochemotherapy (ART). METHODS AND MATERIALS To analyze the exocrine component, the amino acid consumption test and fecal elastase 1 were performed in 13 patients immediately before and 4-8 weeks after(More)
