Influence of adjuvant hormone therapy and chemotherapy on the immune system analysed in the bone marrow of patients with breast cancer.

Purpose: Bone marrow is a special compartment for antitumor immunological memory in patients with breastcancer. Until now, the influence of adjuvant systemic therapy on the immune system has only been investigated in peripheral blood and not in bone marrow. In this study, we analyzed the effect of hormone therapy and chemotherapy on the immune activation status in bone marrow.

Metastatic breast cancer: clinical course, prognosis and therapy related to the first site of metastasis.

Although metastasis is a frequent event in breast cancer patients, insight into the clinical course, prognosis and therapy with respect to the site of the first metastases has been poor and contradictory in former investigations. Follow-up data from 648 patients with metastatic breast cancer were statistically analyzed. Patients with bone metastases at first relapse had better overall survival (median 71 vs.

Does the measurement of four fetal arteries provide more information than the measurement of just two arteries in prenatal Doppler sonography?

Objective: The objective of this study was to evaluate whether the measurement of two or more fetal arteries provides more information and leads to a selection of fetuses at higher risk.

Design: In 244 pregnancies Doppler examinations in four fetal arteries (fetal aorta, common carotid artery, middle cerebral artery, umbilical artery) were performed. The evaluation of the results was made by means of a Doppler score for standardization and systematization.

[Complete remission after salvage chemotherapy in metastatic breast carcinoma after failure of induction cycles of planned high dosage chemotherapy with stem cell support].

We report on a patient with metastatic breast cancer confined to visceral (lung and pleura) site. A high-dose chemotherapy with peripheral progenitor blood cell transplantation was indicated. In contrast to other 24 patients two induction cycle chemotherapies (intensive dosis of Epirubicin/Ifosfamid/GCSF) didn't show any remission of metastases.

Prognostic relevance of cathepsin D detection in micrometastatic cells in the bone marrow of patients with primary breast cancer.

Patients with an elevated level of cathepsin D in breast cancer tissue have an adverse prognosis. This study evaluated the prognostic relevance of cathepsin D detection in disseminated tumour cells in bone marrow. Bone marrow was sampled intraoperatively from both anterior iliac crests in 290 patients with primary breast cancer.

Results of iliac crest biopsies taken from 1465 patients with primary breast cancer.

This study was performed to analyze the relevance of iliac crest biopsy in patients with primary breast cancer with regard to metastases of the primary tumor and osteogenic disease. We performed intraoperative bilateral biopsy of the anterior iliac crests in 1465 patients with primary breast cancer. The bone specimens were histologically evaluated with regard to quality of the biopsy, tumor involvement, and osteogenic and hematogenic disease.

[Doppler score for evaluating perinatal risk].

Doppler sonography now has a definite place in the surveillance of risk pregnancies. Uniform clinical management is sometimes difficult especially in borderline cases. The following study demonstrates the possibility of standardizing and systematizing Doppler results using a score.

Prognostic relevance of urokinase plasminogen activator detection in micrometastatic cells in the bone marrow of patients with primary breast cancer.

Patients with an elevated level of urokinase plasminogen activator (uPA) in breast cancer tissue have an adverse prognosis. This study evaluated the prognostic relevance of uPA detection in disseminated tumour cells in bone marrow. Bone marrow was sampled intraoperatively from both iliac crests in 280 patients with primary breast cancer.

[The clinical value of Doppler ultrasound in obstetrics].

Doppler sonography now has many indications in obstetrical diagnosis. Its wide and often uncritical application was the reason for our study group to confirm its importance. Moreover, we wanted to prove our own procedure.

[Does measurement of absolute velocity by Doppler examination of pregnant patients contribute additional valuable information?].

Ultrasonics is very important for the control of risk pregnancies. Routinely, Doppler-ratios are used to assess fetal danger. The aim of the presented study was to clarify whether measurement of absolute blood flow velocity is useful for the assessment of fetal development as well.

[Initial experiences with a new color technique: ultrasound angiography].

The sonographic diagnosis can be expanded by Color Doppler. Nevertheless something is missing, especially concerning the demonstration of the very slow velocities as it can be found in neovascularized malignant tumors. A recently developed new color technique--the Angio-Color of the Diasonics Corporation, Sonotron (other companies have prototypes of this color)--promises to improve the detection of very low flow velocities.

[Blood supply of malignant and benign tumors of the internal genitals].

Malignant tumours differ mostly from benign lesions in their blood supply. This fact can be used in the sonographic diagnosis of the tumour status. This, however, depends on the availability of ultrasound equipment, capable of demonstrating this difference, which can only be detected in smallest blood vessels, in which the blood flow is extremely slow.

[Effect of intracavitary irradiation on the venous system of the pelvis and leg].

A late complication of combined radiotherapy for malignoma of the inner genital tract is leg edema, whether of venous or lymphatic origin, which is not always clear. To analyse the influence of radiotherapy upon the pelvic and leg venous system, we performed sonographic caliber, occlusion plethysmographic and light reflexion rheographic measurements of veins in 32 patients prior and subsequent to irradiation. No statistically significant difference was found between mean values measured with the different methods.

[The value of Doppler imaging of the aorta, carotid artery and middle cerebral artery in obstetric diagnostics].

The relation of blood blow in the fetal aorta and carotis is a marker for the well being of the unborn child. Increase of cerebral vascularity associated with decrease of blood flow in the aorta is a sign for a fetal risk situation. It is, however, of disadvantage that the fetal carotis is often difficult to image with an wedge-shaped angle between doppler beam and vessel.
