CONTEXT Gemcitabine and 5-fluorouracil (5-FU) sensitize tumor cells to radiation. Furthermore, 5-FU enhances the cytotoxic effect of gemcitabine. OBJECTIVE We report the efficacy and the toxicity of concurrent chemoradiation with gemcitabine and 5-FU in the treatment of patients with locally advanced, unresectable pancreatic cancer. PATIENTS Thirty-two(More)
The purpose of this study was to predict diameters of lesions induced by laser-induced thermotherapy (LITT) of benign prostatic hyperplasia (BPH) from MRI signal/tissue temperature correlations during on-line monitoring with a temperature-sensitive fast low-angle shot (FLASH) sequence. Twenty LITT procedures with Nd:YAG (1,064 nm) and diode (830 nm) lasers(More)
Review of the role of chemoradiotherapy in the treatment of locally advanced pancreatic cancer with a specific focus on the technical feasibility and the integration of chemoradiotherapy into multimodal treatment concepts. Combined chemoradiotherapy of pancreatic cancer is a safe treatment with an acceptable profile of side effects when applied with modern(More)
BACKGROUND Concomitant radiotherapy and chemotherapy with gemcitabine appears to be a promising tool for the treatment of pancreatic cancer since gemcitabine -- applied as single or combination therapy -- proved to have better efficacy in pancreatic cancer than 5-FU containing schemes and furthermore offers radiosensitizing potential. In the present paper(More)
PURPOSE To determine if hypointense lesions clearly outline on T2-weighted fast spin-echo (SE) magnetic resonance (MR) images obtained during coagulative interstitial laser-induced thermotherapy (LITT) of a prostate with benign hyperplasia. MATERIALS AND METHODS In six patients with benign prostatic hyperplasia (BPH), 12 LITT treatments were followed(More)
CONTEXT Primary resectability is expected in up to 20% of pancreatic cancer patients. While most patients relapse with distant metastases, approximately 30% of patients show isolated local recurrence without evidence of distant metastases. OBJECTIVE The present analysis investigates the efficacy of chemoradiotherapy in this particular patient group. (More)
Als neues minimalinvasives Verfahren wird die laserinduzierte interstitielle Thermotherapie (LITT) zunehmend bei tumorösen Raumforderungen eingesetzt. In der Therapie von ausgedehnten Tumoren der Orofazialregion liegen bisher keine Erfahrungen vor. Die anatomische Komplexität dieser Region mit eng benachbarten vaskulären und nervalen Strukturen, an die(More)
Die simultane Radiochemotherapie unter Verwendung von Gemcitabin scheint bei der Behandlung des Pankreaskarzinoms ein hoffnungsvoller Ansatz, da Gemcitabin als Monosubstanz oder in Kombination mit anderen Zytostatika eine verbesserte Wirksamkeit beim (metastasierten) Pankreaskarzinom im Vergleich zu 5-FU-haltigen Therapieschemata zeigt und zudem(More)
Gemcitabine sensitizes tumor cells to radiation and cisplatin and thereby enhances the cytotoxic effect of gemcitabine. Here we report the efficacy and toxicity of concurrent chemoradiation with gemcitabine and cisplatin in the treatment of patients with locally advanced, unresectable pancreatic cancer. A total of 47 patients (29 men, 18 women; median age(More)
PURPOSE To analyze, in a prospective clinical trial, the efficacy and toxicity of concurrent radiotherapy and chemotherapy with gemcitabine and cisplatin in patients with incompletely (R1) resected pancreatic cancer. METHODS AND MATERIALS Between 2000 and 2002, a total of 30 pancreatic cancer patients were treated. Radiotherapy was performed in 15(More)
