Neoadjuvant chemotherapy (NAC), the systematic chemotherapy given to patients with locally advanced and inoperable breast caner, has been proven to be of great clinical values. Many scientific reports confirmed NAC could effectively eliminate sub-clinical disseminated lesions of tumor, and improve long-term and disease-free survival rate of patients with locally advanced breast cancer (LABC); however, up to now, LABC is still a serious clinical issue given improved screening and early diagnosis. This study, with main focus on inoperable LABC, investigated the values of NAC in converting inoperable LABC into operable status and assessed the prognosis...

Single-agent endocrine therapy has been the standard therapeutic choice for the management of hormone receptor (HR)-positive, Her2-negative advanced breast cancer (ABC) for decades. However, the rapidly accumulating data regarding the biological role and safety of CDK4/6 inhibitors and the first-in-class approval of palbociclib have made these novel agents an essential component of treatment for HR-positive ABC. In the frontline setting, palbociclib in combination with endocrine therapy showed an improvement in progression-free survival (PFS) by 10 months to nearly 25 months when compared with endocrine therapy alone and a clinical benefit rate (CBR = stable disease >24 weeks + partial response + complete response) of 85%...

In HER2-positive early breast cancer, neoadjuvant treatment with a combination of sequential chemotherapy and HER2-targeted therapy is currently the standard of care. This is followed by breast surgery, radiotherapy (if indicated), completion of 12 months of HER2-directed therapy, and -depending on the tumor biology - endocrine adjuvant therapy, and ultimately follow up. 10-year survival rates in the HER2-positive subgroup of breast cancer do reach now more than 75% with the introduction of first adjvuant and later neoadjuvant HER2-targeted therapies over the last 15 years...

Primary endocrine therapy is an option in cases of hormone receptor positive and HER2 negative non-metastatic breast cancer. Aromatase inhibitors are considered therapy of choice in postmenopausal patients. In premenopausal patients aromatase inhibitors in combination with LHRH-analogues are regarded superior to tamoxifen. Three different settings have to be discriminated: • Patients too frail for surgery are candidates for primary endocrine therapy in order to control the disease. Treatment duration is determined by the course of the disease...

PURPOSE: Obesity and weight gain after breast cancer (BC) diagnosis can affect cancer outcomes. This study explores the question of weight change during the first 2 years of endocrine treatment (ET) to identify the independent effects of BC diagnosis and treatment on post-diagnosis weight trajectories in early-stage postmenopausal BC survivors. METHODS: The study design is a retrospective chart review. Chi square tests and ANOVA were used to compare patients who gained >2 kg, lost >2 kg, or had stable weight...

BACKGROUND AND OBJECTIVE: It remains controversial whether sentinel lymph node biopsy (SLNB) should be performed before or after neoadjuvant therapy (NAT). We aimed to evaluate the feasibility and accuracy of SLNB before NAT at a single institution, and to determine its relation to patient prognosis. METHODS: A prospective study of T1c-T2-T3 N0 breast cancer patients, after ultrasound examination, who underwent SLNB prior to NAT. Overall, disease-specific and disease-free survival were calculated by Kaplan-Meier curves...

Although neoadjuvant chemotherapy has been widely adopted as it increases breast conservation rates, permits the in vivo testing of the activity of chemotherapeutics and offers the opportunity to conduct translational research based on longitudinal assessments of tumor tissue, neoadjuvant endocrine therapy has been met with skepticism owing to slow regression rates and a low chance for pathologic remission. Areas covered: Herein, the results of clinical trials comparing different endocrine agents as neoadjuvant treatment, endocrine therapy with chemotherapy, treatment duration, novel combinations and putative biomarkers are reviewed, with the aim to better understand the current and future role of this modality in clinical practice...

Purpose To determine the pathologic complete response (pCR) rate in estrogen receptor (ER) -positive primary breast cancer triaged to chemotherapy when the protein encoded by the MKI67 gene (Ki67) level was > 10% after 2 to 4 weeks of neoadjuvant aromatase inhibitor (AI) therapy. A second objective was to examine risk of relapse using the Ki67-based Preoperative Endocrine Prognostic Index (PEPI). Methods The American College of Surgeons Oncology Group (ACOSOG) Z1031A trial enrolled postmenopausal women with stage II or III ER-positive (Allred score, 6 to 8) breast cancer whose treatment was randomly assigned to neoadjuvant AI therapy with anastrozole, exemestane, or letrozole...

Breast cancer is the most common type of cancer and the leading cause of cancer-related death among women worldwide. Hormone receptor-positive (HR+) tumors represent the most common form of this disease, with more than 70% of breast cancers expressing these receptors. Response and benefit to neoadjuvant chemotherapy (NCT) varies according to HR expression, with lower responses in luminal tumors as compared with hormone receptor-negative (HR-) and human epidermal growth factor receptor 2-positive (HER2+) tumors...

Treatment with the CDK4/6 inhibitor abemaciclib, alone or in combination with endocrine therapy, significantly lowered expression of the protein Ki67-a key marker of cell proliferation-in women with hormone receptor-positive, HER2-negative breast cancer. The findings from the phase II neoMONARCH trial suggest that CDK4/6 inhibition may be effective for neoadjuvant treatment of early breast cancer.

BACKGROUND: There is no consensus on the need for adjuvant chemotherapy for patients with pathological residual invasive breast cancer (non-pCR) after neoadjuvant chemotherapy (NAC). We evaluated the tolerability and safety of tegafur-uracil (UFT) as adjuvant chemotherapy for patients with human epidermal growth factor receptor 2-negative breast cancer that resulted in non-pCR after NAC. PATIENTS AND METHODS: We treated patients with 270 mg/m(2) UFT per day for 2 years after definitive surgery and radiotherapy, if necessary...

OBJECTIVES: A decrease in Ki67 during neoadjuvant therapy predicts response to tamoxifen. Previous trials have shown a decreased Ki67 in breast tumors with as little as two or more weeks of preoperative tamoxifen. Shortening the preoperative treatment time in window of opportunity clinical trials makes these trials more attractive to women. POWERPIINC examined the effect of 7 days of preoperative tamoxifen on breast tumor proliferation and patient symptoms. METHODS: Women with untreated stage I/II, ER-positive, invasive breast cancer with no contraindications to tamoxifen were enrolled...

Approximately 70% of patients have breast cancers that are oestrogen receptor alpha positive (ER+) and are therefore candidates for endocrine treatment. Many of these patients relapse in the years during or following completion of adjuvant endocrine therapy. Thus, many ER+ cancers have primary resistance or develop resistance to endocrine therapy during treatment. Recent improvements in our understanding of how tumours evolve during treatment with endocrine agents have identified both changes in gene expression and mutational profiles, in the primary cancer as well as in circulating tumour cells...

Heikki Joensuu
The current standard adjuvant systemic treatment of early HER2-positive breast cancer consists of chemotherapy plus 12months of trastuzumab, with or without endocrine therapy. Several trials have investigated modifications of the standard treatment that are shorter and less resource-demanding (de-escalation) or regimens that aim at dual HER2 inhibition or include longer than 12months of HER2-targeted treatment (escalation). Seven randomized trials investigate shorter than 12months of trastuzumab treatment duration...

Breast cancer is one of the three most common cancers worldwide. Early breast cancer is considered potentially curable. Therapy has progressed substantially over the past years with a reduction in therapy intensity, both for locoregional and systemic therapy; avoiding overtreatment but also undertreatment has become a major focus. Therapy concepts follow a curative intent and need to be decided in a multidisciplinary setting, taking molecular subtype and locoregional tumour load into account. Primary conventional surgery is not the optimal choice for all patients any more...

Paul H Cottu
Neoadjuvant systemic therapies have been extensively evaluated in luminal breast cancer. Conventional cytotoxic chemotherapy increases breast conservation rate, albeit with a low level of complete pathological response of uncertain clinical significance. Endocrine therapies allow similar clinical results with much less side effects. Biological criteria of response to endocrine therapies are still being defined. The neoadjuvant setting must be used for early development of new compounds and to further document biological mechanisms of sensitivity and resistance to treatments...
