Dose-dense biweekly doxorubicin/docetaxel versus sequential neoadjuvant chemotherapy with doxorubicin/cyclophosphamide/docetaxel in operable breast cancer: second interim analysis.

Timing of systemic treatment in primary operable breast cancer is subject to extensive investigation, suggesting that pathologic complete remission (pCR) might improve survival in this setting. The German Adjuvant Breast Cancer Group previously demonstrated the feasibility of a dose-dense biweekly schedule of 4 cycles doxorubicin 50 mg/m2 and docetaxel 75 mg/m2 (ddAT) +/- tamoxifen in the neoadjuvant setting to yield a pCR of 9.7% (Gepardo trial).

A phase II study of topotecan plus gemcitabine in the treatment of patients with relapsed ovarian cancer after failure of first-line chemotherapy.

Background: Second-line chemotherapy for patients with ovarian cancer who failed platinum and paclitaxel treatment remains a therapeutic challenge. We investigated the toxicity profile and therapeutic efficacy of a novel combination regimen, topotecan plus gemcitabine, in a clinical phase II study.

Patients And Methods: Women with relapsed epithelial ovarian cancer after platinum and paclitaxel treatment were eligible to participate in this trial.

First-line chemotherapy with weekly paclitaxel and carboplatin for advanced ovarian cancer: a phase I study.

Objectives: Carboplatin and paclitaxel can be applied safely and effectively as single agents for the treatment of ovarian cancer on a weekly basis. A multicenter, phase-I study was conducted to investigate the maximum tolerated dose of a weekly combination regimen.

Methods: We enrolled 21 patients with primary, surgically resected, advanced ovarian cancer (FIGO III/ IV) and a median age of 59 (range, 35 to 79) years.

Magnetic Resonance Female Breast Imaging (MRFBI) - Evaluation of the Changes in Signal Intensity over Time Pre- and Post-administration of 0.2 mmol/kg Gd-DTPA.

Purpose: We are looking for a threshold value to discriminate between benign and malign breast lesions in MRI of female breast after administration of 0.2 mmol Gadolinum-DTPA/kg bw.

Materials And Methods: Double coil breast MRI (1.

[Comparing the visualization of microcalcifications with direct magnification in digital full-field mammography vs. film-screen mammography].

Purpose: To evaluate the conspicuity of microcalcifications in magnified mammographic views of preparations obtained with full field digital mammography (FFDM), film-screen mammography (FSM), and the DIMA technique.

Material And Methods: Twelve preparations were examined by FFDM and FSM using 1.8 x magnification and DIMA using 7 x magnification.

Telomerase activity in cervical smears.

It is well known that almost all carcinoma cells including those of the uterine cervix have re-established their telomerase activity. However, until now there is no conclusive picture on the telomerase activity in cervical dysplasias and about their relationship to HPV infection. To investigate this question, material from 34 patients (15 with normal epithelium, 11 with LGSIL, 8 with HGSIL) obtained by conventional cervical brushing was used and subjected to non-radioactive TRAP-ELISA (Boehringer Mannheim).

[Preoperative chemotherapy in primary operable breast cancer with a dose-dense combination of doxorubicin and docetaxel (ADoc) - Experience of the GEPARDO-GABG study group].

Objective: The German Adjuvant Breast Cancer Study Group (GABG) conducts trials of preoperative chemotherapy in patients with primary breast cancer using a combination of doxorubicin and docetaxel (ADoc). -

Patients And Methods: We conducted a parallel-grouped phase IIa-study with 42 patients with a conventionally dosed and a dose-dense ADoc-schedule (4 cycles of Doxorubicin 50 mg/m(2), Docetaxel 75 mg/m(2) i. v.

Second-line carboplatin and gemcitabine in platinum sensitive ovarian cancer--a dose-finding study by the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) Ovarian Cancer Study Group.

Background: Despite the progress that has been achieved in the last years, recurrence rates in ovarian cancer patients are still considerably high and the majority of patients ultimately become candidates for second-line treatment. Carboplatin reinduction is a broadly adopted regimen in patients with recurrences occurring six months or later after first-line treatment. Gemcitabine is among the candidates as combination partner in second-line regimens.

The integration of anthracyclines in the treatment of advanced ovarian cancer.

Since the publication of the Gynecologic Oncology Group (GOG) protocol 111 in 1996, and the results of the Arbeitgemeinschaft Gyna kologische Onkologie (AGO) trial Ovar-3 and the GOG protocol 158, the combination of platinum and paclitaxel has been adopted as the standard therapy in advanced ovarian cancer. One option for achieving further progress in the first-line treatment of advanced ovarian cancer might be the addition of noncross-resistant drugs to the two-drug regimen. Meta-analysis showed a survival benefit for platinum-anthracycline based combinations as compared to platinum-based combinations without anthracyclines.

Dose-dense doxorubicin, docetaxel, and granulocyte colony-stimulating factor support with or without tamoxifen as preoperative therapy in patients with operable carcinoma of the breast: a randomized, controlled, open phase IIb study.

Purpose: To investigate the effect of adding tamoxifen to a preoperative dose-dense doxorubicin and docetaxel regimen on the pathologic response of primary operable breast cancer.

Patients And Methods: Patients (tumor size > or = 3 cm, N0 to 2, M0) were prospectively randomized to receive every 14 days a total of four cycles of doxorubicin 50 mg/m2 and docetaxel 75 mg/m(2), either with (ADocT) or without (ADoc) simultaneous tamoxifen. Granulocyte colony-stimulating factor (G-CSF) was routinely given on days 5 to 10.

[Adjuvant chemotherapy of cervix carcinoma--results of a phase II study].

Objective: Therapies involving a radical operation and radiation treatment for cervical carcinoma in stages I and II are not sufficiently effective in patient subgroups with high risk for recurrence. In recent publications, patients with high risk cervical cancer had with adjuvant simultaneous radio-chemotherapy a better disease free and overall survival but a higher toxicity compared with patients received an adjuvant radiotherapy alone.

Material And Methods: 34 patients with at least 2 risk factors for recurrence of cervical cancer were treated with adjuvant chemotherapy after radical hysterectomy.

Detection of HMGI-C in the peripheral blood of breast cancer patients.

The human high mobility group (HMG) protein (HMGI-C) belongs to the HMG family of architectural transcription factors which are expressed only during embryonic development, and not in normal adult tissues. Considerable interest has recently been shown in HMGI-C and its expression in a variety of neoplastic tissues, whereas no expression could be found in normal tissue adjacent to the tumour. So far, no data is available on the expression of HMGI-C in the peripheral blood of patients with solid tumours.

[Dose intensified adjuvant chemotherapy in high risk breast carcinoma with 4-9 positive lymph nodes].

Objective: Taxanes and anthracyclines represent the two most active groups of agents for the treatment of breast cancer. We evaluated this combination in patients with more than 3 positive lymph nodes in an adjuvant, dose-intensive, sequential therapy in comparison with the standard chemotherapy regimen epirubicin/cyclophosphamide in relation to toxicities.

Material And Methods: Since 9/96 127 patients with 4-9/over 9 positive lymph nodes have been recruited from 21 participating centers in an ongoing trial.

Pre-operative staging of cervical cancer: comparison of magnetic resonance imaging (MRI) and computed tomography (CT) with histologic results.

Thirty-two patients with histologically confirmed cervical carcinoma were preoperatively investigated using MRI; in addition, a CAT-scan was performed on 15 of these patients. The diagnostic results using both modalities were compared with the histological findings (after hysterectomy according to Wertheim-Meigs, including lymph node dissection in the pelvic and, in part, in para-aortal regions). Determination of tumour volume was possible with high accuracy using MRI.

Dose- intensified, preoperative and adjuvant chemotherapy in patients with T3- and T4- breast cancer: toxicity, clinical and pathological remission.

Objective: The aim of the study was to investigate a dose-intensified, preoperative chemotherapy with 3 cycles (cy) of epirubicin 60 mg/m2, ifosfamide 5 g/m2 with mesna 5 g/m2, biweekly with G-CSF 5 micrograms/kg (filgrastim), in terms of toxicity, clinical and pathological remission rates and changes of immunohistochemical characteristics (ER, PR, c-erbB2, p53) during chemotherapy of inoperable patients (pt) with poor prognosis (locally advanced (LABC, 9 pt), inflammatory breast cancer (IBC, 12 pt) and M0.

Patients And Methods: Following preoperative chemotherapy (63 cy) and mastectomy patients received adjuvant 3 cy of epirubicin 60 mg/m2 and paclitaxel 175 mg/m2 (biweekly) with G-CSF (54 cy), and subsequently radiation of the thoracic wall and tamoxifen 20 mg/day.

Results: Primary toxicity (T): grade 3 alopecia (21 pt), grade 3-4 leucopenia (7 cy), grade 1-2 leucopenia (26 cy), grade 1-2 anemia (61 cy), grade 1-2 neurocortical T (13 cy), grade 1-2 neurosensory T (7 cy), grade 1 cardiac toxicity (1 pt).

CD99 positivity and EWS-FLI1 gene rearrangement identify a breast tumor in a 60-year-old patient with attributes of the Ewing family of neoplasms.

Rearrangements of the EWS gene with ETS transcription factor genes as a result of chromosomal translocation and high expression levels of CD99MIC2 characterize the Ewing family of tumors (EFT). This group of rather undifferentiated neoplasms affects bone and soft tissue in children and young adults mostly between 5 and 30 years of age (median, 15 years). This study reports a case of a CD99MIC2 positive small round cell tumor in the breast of a 60-year-old woman in whom a t(11;22)(q24;q12) chromosomal aberration was identified by cytogenetic analysis.

Maximized reduction of primary breast tumor size using preoperative chemotherapy with doxorubicin and docetaxel.

Purpose: To assess the toxicity and efficacy of preoperative chemotherapy with doxorubicin and docetaxel in patients with primary operable breast cancer.

Patients And Methods: Forty-two patients with histologically confirmed primary breast cancer tumors of at least 2 cm in diameter received doxorubicin (50 mg/m(2) intravenously [IV] over 15 minutes) and docetaxel (75 mg/m(2) IV over 1 hour) every 14 (24 patients) or 21 (18 patients) days for four cycles.

Results: The median size of the primary tumor decreased significantly, from 4 cm (range, 2 to 10 cm) to 2 cm (range, 0 to 5 cm) on physical examination and from 3.

The role of docetaxel (Taxotere) in neoadjuvant chemotherapy of breast cancer.

Neoadjuvant chemotherapy has become standard therapy in the management of breast cancer patients with locally advanced disease with inoperable tumors and inflammatory breast cancer. Patients with earlier stage breast cancer and operable tumors may also benefit from treatment with neoadjuvant chemotherapy. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Collegeville, PA) is thought to be one of the most potent agents in the treatment of metastatic breast cancer and is therefore being investigated for its likely benefit in preoperative, neoadjuvant regimens.

Comparison of various imaging methods with particular evaluation of color Doppler sonography for planning surgery for breast tumors.

Objective: Color Doppler sonography (CD) was compared with other diagnostic imaging methods [mammography (MG), breast ultrasound (US) and magnetic resonance imaging (MRI)] in the planning of surgery for breast tumors.

Materials And Methods: 99 patients with breast cancer and 101 with ultimately benign breast lesions were examined preoperatively. The specificity and sensitivity were calculated, as well as the predictive values.

Increased incidence of cervical intraepithelial neoplasia in young women in the Mitte district, Berlin, Germany.

Objective: To investigate whether the incidence of cervical intraepithelial neoplasia (CIN), in particular of high grade CIN, increased in Berlin during the period 1970-1989 and whether the ages of women with CIN had decreased.

Study Design: In the former German Democratic Republic, which had a highly centralized public health system, all gynecologic operations performed on women living in the Mitte district of Berlin were carried out during the period 1970-1989 (when the Berlin Wall fell) in the gynecologic clinic of the Charité Hospital.

Results: The incidence of all CIN increased from year to year over the observation period: 0.

[Preoperative chemotherapy of breast carcinoma].

Preoperative chemotherapy represents the standard procedure in inflammatory breast cancer. However, only recently it could be demonstrated that preoperative chemotherapy is beneficial even for patients with operable primary breast cancer. The number of breast conserving surgeries could be increased significantly.

[Optimal use of MRI mammography from the economic viewpoint].

With the introduction of the contrast agent gadolinum DTPA there were hopes that "MRM" would prove to be the investigatory technique that would largely solve the problems of breast diagnostics. However, after the early years of acceptance, the new method of investigation became a subject of controversy. Nonetheless, MRM today occupies a recognized place in diagnostics for certain indications.

Combined treatment of inoperable carcinomas of the uterine cervix with radiotherapy and regional hyperthermia. Results of a phase II trial.

Aim: The disappointing results for inoperable, advanced tumors of the uterine cervix after conventional radiotherapy alone necessitates improving of radiation therapy. Simultaneous chemotherapy or altered radiation fractionation, such as accelerated regimen, increase acute toxicity and treatment is often difficult to deliver in the planned manner. The purpose of this phase II study was to investigate the toxicity and effectiveness of a combined approach with radiotherapy and regional hyperthermia.

[Cervix carcinoma: staging, therapy, after-care. Experiences with magnetic resonance tomography of cervix carcinoma based on recent literature 1993 to 1997].

The investigation of cervix carcinoma with magnetic resonance tomography (MRT) is still controversially discussed with regard to its diagnostic value as well as for planning radiation therapy. The purpose of this article is to present and discuss papers published between 1993 and 1997 in this field with respect to the technique used, the contrast media applied and its clinical value. A literature search using three different databases (Medline, Embase, Cancerlit) identified 39 publications, which were then analysed.

Detection of malignant and benign breast lesions with an automated US system: results in 120 cases.

Purpose: To evaluate clinically an automated ultrasound (US) system for detecting benign and malignant breast lesions.

Materials And Methods: A prototype automated US system was used to examine 119 patients: 38 patients with 39 proved malignant breast lesions (7-50 mm), 41 patients with 41 proved benign breast lesions (8-40 mm), and 40 patients without breast lesions. The device yields a three-dimensional set of B-mode scans and reconstructed US images comparable to mammograms.
