Adjuvant anastrozole versus exemestane versus letrozole, upfront or after 2 years of tamoxifen, in endocrine-sensitive breast cancer (FATA-GIM3): a randomised, phase 3 trial

Background: Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer. Methods: FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer. Eligible patients had histologically confirmed invasive hormone receptor-positive breast cancer that had been completely remov…

Metronomic Chemotherapy (mCHT) in HER2-ve Advanced Breast Cancer (ABC) Patients (PTS): When Care Objectives Meet Patients’ Need. Preliminary Results of the Victor-6 Study

The Risk of Toxicities from Trastuzumab, Alone or in Combination, in an Elderly Breast Cancer Population

<b><i>Background:</i></b> Breast cancer in the elderly is associated with high recurrence and death rates, due mostly to undertreatment. Human epidermal growth factor receptor type 2 (HER2) overexpression is infrequent in older patients. Trastuzumab-based chemotherapy is often withheld from elderly patients because of its cardiotoxicity. <b><i>Patients and Methods:</i></b> Medical records of consecutive HER2-positive breast cancer patients aged ≥70 years old treated between 2005 and 2010 in the participating centers were retrospectively reviewed. All patients underwent multidimensional geriatric assessment (MGA). <b><i>Results:<…

Safety of trastuzumab, alone or in combination, in elderly patients with HER2-positive breast cancer: A 5-year case series.

e11056 Background: Breast cancer (BC) is frequent in the elderly and is burdened by high recurrence and death rates, due mostly to undertreatment. Trastuzumab (T), in combination with chemotherapy (CT) or hormonotherapy (HT), is a well-established treatment strategy for early and advanced HER2-positive (HER2+) breast cancer, but has been poorly studied in the elderly setting due to its infrequency. The aim of our study is to assess the safety of T in elderly patients with HER2+ BC. Methods: Between 2005 and 2010, consecutive HER2+ breast cancer patients of ≥70 years of age referred to two oncology centers and that received T-based therapy were retrospectively reviewed. All patients were tr…

Safety and activity of trastuzumab-containing therapies for the treatment of metastatic breast cancer: our long-term clinical experience (GOIM study).

Background: Trastuzumab is widely used as the treatment of choice for HER2-positive metastatic breast cancer (MBC). Patients and methods: Seventy patients, median age 57 years and range 31-81 years, were included in our retrospective analysis with the aim to evaluate safety and activity of trastuzumab-containing therapies. Results: We observed for first-line treatment response rate (RR) 41%, stable disease (SD) 47% and time to progression (TTP) 8 months (range 1-44). Corresponding numbers for second line were RR 23%, SD 62% and (TTP) 9 months (range 3-23) and beyond second line RR 22%, SD 78% and (TTP) 9 months (range 4-19). Overall survival was 19.2 months (3-62 months). The median cumulat…

Metronomic chemotherapy (mCHT) in HER2-ve advanced breast cancer (ABC) patients (pts): What has changed over the time? Preliminary results of the VICTOR-6 study

e12552 Background: mCHT is the minimum biologically effective dose of a chemotherapeutic agent, given at regular dosing regimen with no prolonged drug free interval, that leads to anti-tumor activity. Old regimens included Cyclophosphamide-Methotrexate (CM), whereas in the last years new regimens, such as Vinorelbine (VRL) and Capecitabine (CAPE)-based have been developed. Aim of this observational retrospective ongoing study is to describe the use of mCHT in ABC pts across 5 years and the clinical characteristics of the pts together with efficacy of old (CM-like) vs new (VRL/CAPE-based) metronomic regimens in terms of response and disease control. Methods: We retrospectively identified fr…
