Der Ophthalmologe > 2006 > 103 > 1 > 48-51

HintergrundDie Prävalenz der intraokularen Metastasierung beim Mammakarzinom wird mit 4–5% angegeben. Eine solitäre Irismetastase als Erstmanifestation ohne Nachweis sonstiger Sekundärtumoren ist unseres Wissens bislang nicht beschrieben worden. Wir berichten über die erfolgreiche Therapie mittels Elektronenbestrahlung.KasuistikEine 30-jährige Patientin stellte sich mit einem amelanotischen Iris-Kammerwinkel-Tumor...

Radiation therapy of stage I and II non-small cell lung cancer (NSCLC)

D. Zierhut, C. Bettscheider, K. Schubert, M. van Kampen, more

Lung Cancer > 2001 > 34 > Supplement 3 > 39 - 43

Surgery is the preferred and standard treatment for patients with resectable stage I and II non-small cell lung cancer (NSCLC). Survival rates of local surgery are unbeaten by other treatment modalities. Up to 70% of these patients survive 5 years or longer. However, there is a subset of patients who either are inoperable due to the presence of severe associated diseases, or who refuse surgery. In...

Raumforderung im Bereich der Schdelbasis

D. Schulz-Ertner, D. Zierhut, B. Romaneehsen, M. Wannenmacher

Der Radiologe > 1999 > 39 > 2 > 161-163

Bei einem 62-jhrigen Patienten mit Mukotympanon, begleitendem Tinnitus und Hrverschlechterung zeigte sich computertomographisch eine Raumforderung im Bereich des linken Keilbeines mit Obstruktion der Tuba auditiva als Ursache fr die Beschwerden. Nach Durchfhrung einer transnasalen Biopsie und histologischer Aufarbeitung wurde uns der Patient von einer auswrtigen Klinik unter der Diagnose eines reparativen...

Sonographic criteria for the staging and follow-up of malignant lymphomas

U. Mende, D. Zierhut, V. Ewerbeck, R. Haas, more

Der Radiologe > 1997 > 37 > 1 > 19-26

Ultrasonography is an integral part of the radiological imaging of malignant lymphomas for staging, therapy planning, monitoring, follow-up, post-therapeutic care, and detection of recurrences, as well as the diagnostic differentiation of benign lesions and metastasis of solid tumors. None of the imaging methods, including sonography, however, can safely determine the stage (UICC certainty level C4)...

Cataract incidence after total-body irradiation

D. Zierhut, F. Lohr, P. Schraube, P. Huber, more

International Journal of Radiation Oncology, Biology, Physics > 1997 > 39 > 21001 > 326

Purpose: Aim of this retrospective study was to evaluate cataract incidence in a homogeneous group of patients after total-body irradiation followed by autologous bone marrow transplantation or peripheral blood stem cell transplantation.Method and Materials: Between 11/1982 and 6/1994 in total 260 patients received in our hospital total-body irradiation for treatment of haematological malignancy....

475 Conformal radiotherapy of localized prostatic carcinoma: Acute tolerance and early evaluation of effectiveness

D. Zierhut, M. Flentje, R. Engenhan, V. Rudat, more

European Journal of Cancer > 1995 > 31 > Supplement 6 > S102

Acute tolerance and early effectiveness of conformal 3D-planned radiotherapy of prostate cancer was investigated in a prospective trial.32 men (44–80 years old) with locally advanced carcinoma of the prostate (stage B2 or C) have been treated by 3D-planned conformal radiotherapy using high energy photons. Total doses from 50 to 70Gy (mean: 63.9±4.9Gy) were applied with single doses of 2.0Gy in 46±4days...

457 Variability of patient positioning and prostate motion in 3D conformal radiotherapy of localized prostate cancer

V. Rudat, P. Schraube, M. Flentje, D. Oetzel, more

European Journal of Cancer > 1995 > 31 > Supplement 6 > S98

The variability of patient positioning and prostate motion was determined and possible consequences of both errors on the calculated dose distribution in 3D conformal radiotherapy estimated.Patient positioning variability was measured by comparing 54 orthogonal simulator films with 125 corresponding portal films from 27 patients. Prostate motion variability was determined by 107 computed tomography...
