Single Institution trial of anthracycline- and taxane-based chemotherapy for operable breast cancer: The ASTER study.

The efficacy of anthracycline- and taxane-based chemotherapy for perioperative treatment of breast cancer (BC) has been established. No superiority of a cytotoxic regimen has been demonstrated, provided that administration of an anthracycline and a taxane is warranted. The ASTER study was designed to investigate the safety of 6 months of perioperative chemotherapy with Doxorubicin and Paclitaxel, followed by Cyclophosphamide, Methotrexate, and 5-Fluorouracil.

p53 status identifies triple-negative breast cancer patients who do not respond to adjuvant chemotherapy.

Genomic analysis and protein expression assimilate triple-negative breast cancers (TNBC) with basal-like breast tumors. TNBCs, however, have proved to encompass also tumors with normal-like phenotype and known to have favorable prognosis and to respond to chemotherapy. In a recent paper, we have provided evidence that p53 status is able to subdivide TNBCs into two distinct subgroups with different outcome, and consistent with basal- and normal-like phenotypes.

Neoadjuvant and adjuvant trastuzumab in patients with HER2-positive locally advanced breast cancer (NOAH): follow-up of a randomised controlled superiority trial with a parallel HER2-negative cohort.

Background: In our randomised, controlled, phase 3 trial NeOAdjuvant Herceptin (NOAH) trial in women with HER2-positive locally advanced or inflammatory breast cancer, neoadjuvant trastuzumab significantly improved pathological complete response rate and event-free survival. We report updated results from our primary analysis to establish the long-term benefit of trastuzumab-containing neoadjuvant therapy.

Methods: We did this multicentre, open-label, randomised trial in women with HER2-positive locally advanced or inflammatory breast cancer.

Axillary lymph node dissection versus no dissection in patients with T1N0 breast cancer: a randomized clinical trial (INT09/98).

Background: Although axillary surgery is still considered to be a fundamental part of the management of early breast cancer, it may no longer be necessary either as treatment or as a guide to adjuvant treatment. The authors conducted a single-center randomized trial (INT09/98) to determine the impact of avoiding axillary surgery in patients with T1N0 breast cancer and planning chemotherapy based on biological factors of the primary tumor on long-term disease control.

Methods: From June 1998 to June 2003, 565 patients aged 30 years to 65 years with T1N0 breast cancer were randomized to either quadrantectomy with (QUAD) or without (QU) axillary lymph node dissection; a total of 517 patients finally were evaluated.

Maspin influences response to doxorubicin by changing the tumor microenvironment organization.

Altered degradation and deposition of extracellular matrix are hallmarks of tumor progression and response to therapy. From a microarray supervised analysis on a dataset of chemotherapy-treated breast carcinoma patients, maspin, a member of the serpin protease inhibitor family, has been the foremost variable identified in non-responsive versus responsive tumors. Accordingly, in a series of 52 human breast carcinomas, we detected high maspin expression in tumors that progressed under doxorubicin (DXR)-based chemotherapy.

Recurrence and mortality dynamics for breast cancer patients undergoing mastectomy according to estrogen receptor status: different mortality but similar recurrence.

(Cancer Sci 2010; 101: 826-830) The purpose was to ascertain whether the recurrence risk patterns for patients with estrogen receptor (ER)-positive (P) and ER-negative (N) breast cancer support the ER-related clinical divergence suggested by the observed different mortality patterns and gene expression profiles. Both recurrence and death were considered in a series of 771 patients undergoing mastectomy. ER status was available for 539 patients.

Capecitabine/Cyclophosphamide/Methotrexate for patients with metastatic breast cancer: a dose-finding, feasibility, and efficacy study.

Background: Capecitabine is a fluoropyrimidine carbamate that acts as a prodrug, mimics continuous infusion of 5-fluorouracil (5-FU), and has encouraging antitumor activity in women with metastatic breast cancer. We performed a feasibility study in which the 5-FU of the cyclophosphamide/methotrexate/5-FU regimen was substituted with capecitabine in a novel regimen applicable to women with breast cancer. Three doses of capecitabine were explored (1650 mg/m2, 1850 mg/m2, and 2000 mg/m2 per day from day 1 to day 14) in combination with intravenous bolus cyclophosphamide (600 mg/m2) and methotrexate (40 mg/m2), given on day 1 and day 8 every 4 weeks.

30 years' follow up of randomised studies of adjuvant CMF in operable breast cancer: cohort study.

Objective: To assess the long term effectiveness of adjuvant treatment with cyclophosphamide, methotrexate, and fluorouracil (CMF) in patients with operable breast cancer at risk of relapse, on the basis of three successive randomised trials and one observational study conducted from June 1973 to December 1980.

Design: Cohort study.

Setting: Istituto Nazionale Tumori in Milan, Italy.

Clinical relevance of different sequencing of doxorubicin and cyclophosphamide, methotrexate, and Fluorouracil in operable breast cancer.

Purpose: To assess the clinical relevance of different sequences of doxorubicin (DOX) and cyclophosphamide, methotrexate, and fluorouracil (CMF) in patients with operable breast cancer at risk of disease relapse.

Patients And Methods: Two randomized trials were activated in the early 1980s. The first study, in patients with one to three involved nodes, was intended to assess the effectiveness of intravenous (i.

HER2 overexpression and doxorubicin in adjuvant chemotherapy for resectable breast cancer.

Purpose: Human epidermal growth factor receptor 2 (HER2) overexpression was found to predict a good response in breast carcinoma patients treated with doxorubicin (Adriamycin [ADM]). Evidence from our recent study indicates that node-positive patients respond to cyclophosphamide, methotrexate, and fluorouracil (CMF) regardless of HER2 status. We address the issue of whether therapy regimens including CMF and ADM versus CMF alone have the same therapeutic effect in patients with HER2+ and HER2- tumors in terms of relapse-free survival (RFS) and overall survival (OS).
