Eribulin as first-line treatment in older patients with advanced breast cancer: A multicenter phase II trial [SAKK 25/14].

Introduction: Standard-dose eribulin mesylate (1.4 mg/m d1 + 8) achieves clinical benefit rates of 26%-52% in patients with metastatic breast cancer (mBC). <10% of patients in the registration trial were ≥ 70 years old; dose reductions were common in these older patients.

Ki-67 assessment in early breast cancer: SAKK28/12 validation study on the IBCSG VIII and IBCSG IX cohort.

The assessment of Ki-67 in early-stage breast cancer has become an important diagnostic tool in planning adjuvant therapy, particularly for the administration of additional chemotherapy to hormone-responsive patients. An accurate determination of the Ki-67 index is of the utmost importance; however, the reproducibility is currently unsatisfactory. In this study, we addressed the predictive/prognostic value of Ki-67 index assessed by using the most reproducible methods, which were identified in the pilot phase.

Association of Somatic Driver Alterations With Prognosis in Postmenopausal, Hormone Receptor-Positive, HER2-Negative Early Breast Cancer: A Secondary Analysis of the BIG 1-98 Randomized Clinical Trial.

Importance: A range of somatic driver alterations has been described in estrogen receptor-positive, HER2-negative (ER+/HER2-) early breast cancer (BC); however, the clinical relevance is unknown.

Objective: To investigate associations of driver alterations with prognosis and the role of PIK3CA mutations in prediction of benefit associated with endocrine therapy in postmenopausal patients with ER+/HER2- early BC treated with tamoxifen or letrozole.

Design, Setting, And Participants: The Breast International Group (BIG) 1-98 trial randomized 8010 postmenopausal patients with hormone receptor-positive, operable, invasive BC to monotherapy with letrozole, tamoxifen, or a sequential strategy for 5 years.

A population-based analysis of secondary malignancies in breast cancer patients receiving breast reconstruction.

Background: There is an ongoing debate about the relationship between breast implants and secondary malignancies.

Methods: Breast cancer patients undergoing surgical reconstruction after mastectomy by either implants or autologous flap were identified in the Surveillance, Epidemiology and End Results registry between 1998 and 2002. The occurrence of secondary malignancies at least 1 year after diagnosis was compared between breast reconstruction with implants vs autologous flap.

Improved Survival After Primary Tumor Surgery in Metastatic Breast Cancer: A Propensity-adjusted, Population-based SEER Trend Analysis.

Background: There is ongoing debate about nonpalliative primary tumor surgery in metastatic breast cancer patients. This issue has become even more relevant with the introduction of increasingly sensitive imaging modalities.

Methods: Metastatic breast cancer patients were identified in the SEER registry between 1998 and 2009.

Breast cancer patients on endocrine therapy reveal more symptoms when self-reporting than in pivotal trials: an outcome research study.

Objectives: The purpose of this investigation was firstly to assess the overall frequency of subjectively experienced symptoms self-reported by patients receiving endocrine therapy and secondly to compare these symptoms with side effects assessed by clinicians in pivotal trials.

Methods: Unselected patients with early and advanced breast cancer receiving endocrine therapy were approached consecutively during a routine outpatient visit. They received a questionnaire called Checklist for Patients with Endocrine Therapy (C-PET), a validated self-assessment tool to determine prespecified symptoms associated with endocrine therapy.

Prevention of docetaxel- or paclitaxel-associated taste alterations in cancer patients with oral glutamine: a randomized, placebo-controlled, double-blind study.

Taste alteration (dysgeusia), an underrecognized toxicity associated with taxane-based chemotherapy (TaxCh), lacks standard treatment. We investigated prevention of dysgeusia with oral glutamine in patients undergoing first-time TaxCh. Adult patients were randomized to receive either 30 g/day glutamine or placebo (maltodextrin) from day 1 of TaxCh.

Pegylated liposomal doxorubicin-associated hand-foot syndrome: recommendations of an international panel of experts.

Background: Hand-foot syndrome (HFS) is dose-limiting and the most common cumulative toxicity associated with pegylated liposomal doxorubicin (PLD). It can cause considerable discomfort and lead to therapy interruption. Numerous approaches to HFS management have been reported, but there is no consensus.

Letrozole as upfront endocrine therapy for postmenopausal women with hormone-sensitive breast cancer: BIG 1-98.

The BIG 1-98 trial is a large, randomized, independently conducted clinical trial designed to compare the efficacy of upfront letrozole versus tamoxifen monotherapy and to compare sequential or up-front use of letrozole and/or tamoxifen as an early adjuvant therapy for patients with early breast cancer. We report on the results from the primary core analysis of the BIG 1-98 trial of 8,010 patients, which compares monotherapy with letrozole versus tamoxifen. This pre-planned core analysis allowed the use of patient data from the monotherapy arms of letrozole and tamoxifen and from the sequential arms prior to the drug switch point.

Guidelines for the adjuvant treatment of postmenopausal women with endocrine-responsive breast cancer: past, present and future recommendations.

Treatment guidelines are useful tools that enable physicians to integrate the latest clinical research into their practices. The large volume of rapidly evolving clinical data in breast cancer has been summarised and incorporated into treatment recommendations by well-known and reliable institutions, including the National Comprehensive Cancer Network, the American Society for Clinical Oncology, the European Society for Medical Oncology and the St. Gallen International Consensus Panel.

Letrozole as adjuvant endocrine therapy in postmenopausal women with breast cancer.

The third-generation aromatase inhibitor letrozole offers a promising approach to treating hormone-sensitive breast cancer for postmenopausal women, through potent and specific inhibition of estrogen synthesis. In neoadjuvant and first-line treatment, letrozole demonstrated superior efficacy compared with tamoxifen in randomized Phase III trials. Initial results of Breast InterGroup 1-98, a large ongoing randomized trial investigating primary adjuvant endocrine treatment with either letrozole or tamoxifen, have recently been presented.
