This phase III study compared docetaxel and doxorubicin in patients with metastatic breast cancer who had received previous alkylating agent-containing chemotherapy.Patients were randomized to receive an intravenous infusion of 100 mg/m(2) or 75 every 3 weeks for a maximum seven treatment cycles.A total 326 randomized, 165 161 docetaxel. Overall, produced significantly higher rate objective response than did (47.8% v 33.3%; P =.008). Docetaxel was also more active negative prognostic...

Assessment of prognostic markers in breast cancer independent the axillary lymph node status is major concern for application adjuvant treatment regimens. The current decision based mainly on status. Because improved screening methods, number and proportion patients with node-negative disease are increasing, which warrants a search reliable parameters. tumor suppressor gene expression appears to be especially suited as marker progress malignant cellular dedifferentiation.Tumor tissues 156...

BackgroundWe carried out a prospective clinical study to evaluate the impact of Recurrence Score (RS) on treatment decisions in early breast cancer (EBC).Patients and methodsA total 379 eligible women with estrogen receptor positive (ER+), HER2-negative EBC 0–3 lymph nodes were enrolled. Treatment recommendations, patients' decisional conflict, physicians' confidence before after knowledge RS actual data recorded.ResultsOf 366 assessable patients 244 node negative (N0) 122 (N+)....

Neoadjuvant systemic treatment (NST) elicits a pathologic complete response in 40%-70% of women with breast cancer. These patients may not need surgery as all local tumor has already been eradicated by NST. However, nonsurgical approaches, including imaging or vacuum-assisted biopsy (VAB), were able to accurately identify without residual cancer the axilla. We evaluated feasibility machine learning algorithm (intelligent VAB) exceptional responders NST.We trained, tested, and validated using...

Objective: We evaluated the ability of minimally invasive, image-guided vacuum-assisted biopsy (VAB) to reliably diagnose a pathologic complete response in breast (pCR-B). Summary Background Data: Neoadjuvant systemic treatment (NST) elicits up 80% women with cancer. In such cases, surgery, gold standard for confirming pCR-B, may be considered overtreatment. Methods: This multicenter, prospective trial enrolled 452 presenting initial stage 1-3 cancer all biological subtypes. Fifty-four...

Pathological morphological changes in tumor tissue enable collective cancer cell unjamming, a cellular motility transition. However, fundamental questions remain: Is unjamming essential for progression? Which different states can be found patients? Here, vital tracking patient-derived solid explants (N=16) reveals that of recognized by elongated and nucleus shape (CeNuS) low number density. These static variables serve as morphodynamic link to map the broad range morphologies associated...

Abstract Purpose: The predictive value of topoisomerase-IIα (topo-II) has been evaluated in advanced breast cancer patients randomly treated with single-agent doxorubicin or docetaxel. Experimental design: Primary tumor samples from enrolled a randomized, phase III clinical trial comparing (75 mg/m2 q3wks) docetaxel (100 were collected and topo-II status was by immunohistochemistry (clone KiS1). Results: Topo-II 108 samples, 55 (51%) the arm 53 (49%) arm. An increment 10% cells expressing is...

Objective:The 21-gene assay (Oncotype DX Breast Cancer Test (Genomic Health Inc., Redwood City, CA)) is a well validated test that predicts the likelihood of adjuvant chemotherapy benefit and 10-year risk distant recurrence in patients with ER+, HER2− early-stage breast cancer. The aim this analysis was to evaluate cost-effectiveness using inform decisions Germany.Methods:A Markov model developed make long-term projections recurrence, survival, quality-adjusted life expectancy, direct costs...

The goal in breast conserving surgery (BCS) of ductal carcinoma situ (DCIS) is removal the tumor with a clear surgical margin. However, re-excision rates are regrettably high. To date, there no adequate procedures for intraoperative margin assessment DCIS. A multicenter, single arm study was conducted to evaluate benefit novel device (MarginProbe®) during BCS DCIS, associated reduction re-excisions and cosmetic outcome treated patients. We present results 42 patients enrolled 3 German...
