OBJECTIVE: The most common procedure to prevent seroma formation, a common complication after breast and axillary surgery, is to use prophylactic surgical drains. Ongoing discussions continue regarding the ideal time for removing drains after surgical procedures. In this study, we aimed to investigate factors that affect drain indwelling time (DIT). MATERIALS AND METHODS: From 2014 to 2015, a total of 91 consecutive patients with breast cancer were included in the study...

Introduction The placement of intramammary marker clips has proven to be helpful for tumor localization in patients undergoing neoadjuvant chemotherapy and breast-conserving surgery. The purpose of our study was to investigate the feasibility of using a clip marker system for breast cancer localization and its influence on the imaging assessment of treatment responses after neoadjuvant chemotherapy. Patients and Methods Between March and June 2015, a total of 25 patients (n = 25), with a suspicion of invasive breast cancer with diameters of at least 2 cm (cT2), underwent preoperative sonographically guided core needle biopsy using a single-use breast biopsy system (HistoCore™) and intramammary clip marking using a directly adapted clip system based on the established O-Twist Marker™, before their scheduled preoperative neoadjuvant chemotherapy...

Introduction This prospective study reports on the impact of psychological factors on women with primary breast cancer undergoing neoadjuvant chemotherapy. These women are in a special situation, where they not only have to deal with the shock of the cancer diagnosis but also with the fact that the malignant tumor will not be removed immediately but only after completing chemotherapy. A situation like this is stressful and requires a personal strength which not every woman may have. Methods In a prospective study 53 patients were assessed using various psychological and psycho-oncological questionnaires which aimed to evaluate their psychological stress and their coping resources...

The management of soft tissue sarcoma is challenging and varied. Centralisation of management in high volume specialist centres has revolutionised outcomes. Surgery remains the mainstay of treatment and is currently the only potentially curative therapy. Retroperitoneal soft tissue sarcoma presents a particular challenge to the surgical oncologist and the concept of extended resection to include surrounding expendable organs taken en bloc with the tumour has now largely been adopted. The use of neoadjuvant and adjuvant therapies for retroperitoneal soft tissue sarcoma is still to be established, although they are employed on a case-specific basis...

Background: HER2 ( ERBB2 ) gene amplification and its corresponding overexpression are present in 15-30% of invasive breast cancers. While HER2-targeted agents are effective treatments, resistance remains a major cause of death. The American College of Surgeons Oncology Group Z1041 trial (NCT00513292) was designed to compare the pathologic complete response (pCR) rate of distinct regimens of neoadjuvant chemotherapy and trastuzumab, but ultimately identified no difference [1]. Patients and methods: In supplement to tissues from 37 Z1041 cases, 11 similarly treated cases were obtained from a single institution study (NCT00353483)...

AIMS: Preoperative core needle biopsy (CNB) is commonly used to confirm the diagnosis of breast cancer. For treatment purposes and for determining histological type, especially in case of neoadjuvant therapy, oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) status and E-cadherin assessments are crucial. Considering the increasing demand for same-day diagnosis of breast lesions, an accelerated method of CNB processing was developed, in which the tissue fixation time is radically reduced...

Cancer immunology has gained renewed interest in the past few years due to emerging findings on mechanisms involved in tumoral immune evasion. Indisputably, immune edition is currently considered a critical hallmark of cancer. Basic research has revealed new targets which can be modulated in the clinical setting with new compounds and strategies. As recent evidence confirms, breast cancer (BC) is a complex and heterogeneous disease in which host immune responses play a substantial role. T-infiltrating lymphocytes measurement is suggested as a powerful new tool necessary to predict early BC evolution, especially in HER2-positive and triple negative subtypes...

BACKGROUND: As we are moving away from the traditional chemotherapy era to targeted therapy, the validity of old assessment paradigms associated with therapeutics are being raised in the context of immunotherapy. The old paradigm required elaborate assessment of toxicity with no expectation of efficacy in early phase trials. Safety data from Phase 1 and 2 studies with many immunotherapeutics show that they display limited toxicities and draw attention to the need to demonstrate efficacy in the early evaluation of new agents...

PURPOSE: The GeparSepto study demonstrated that the use of nab-paclitaxel instead of paclitaxel prior to anthracycline-based chemotherapy could lead to a significantly increased pCR rate, especially in the triple negative subpopulation. We report efficacy and safety for patients treated with two different doses of nab-paclitaxel in comparison to weekly solvent-formulated paclitaxel. METHODS: Patients were treated for 12 weeks with either intravenous nab-paclitaxel 150 mg/m(2) (nP150) weekly, after study amendment 125 mg/m(2) (nP125) weekly or solvent-based paclitaxel 80 mg/m(2) (P80) weekly followed by epirubicin 90 mg/m(2) and cyclophosphamide 600 mg/m(2) on day 1 for four 3-week cycles...

BACKGROUND: The primary objective was to determine whether mid-treatment ultrasound measurements of index breast tumors and index axillary nodes of different cancer subtypes associate with residual cancer burden (RCB). METHODS: Patients with invasive breast cancer who underwent neoadjuvant chemotherapy and had pre-treatment and mid-treatment breast and axillary ultrasound were included in this single-institution, retrospective cohort study. Linear regression analysis assessed associations between RCB with (a) change in index breast tumor size, (b) change in index node size, and (c) absolute number of abnormal nodes at mid-treatment...

In 2010, the ACOSOG Z0011 trial showed equivalent survival and recurrence between sentinel lymph node biopsy (SLNB) alone versus axillary lymph node dissection (ALND) for those with a tumor positive sentinel node (SN). We examined national trends in axillary surgery following neoadjuvant chemotherapy (NAC) for clinically node positive disease in the years prior to and after the Z0011 trial publication. 12,063 women with cT1-4N1M0 invasive breast cancer who underwent NAC from 2006 to 2013 and had 1-3 positive nodes on pathology were selected from the National Cancer Data Base...

Introduction In breast cancer management, the role of adjuvant radiation therapy (RT) has been the subject of intense controversy over the past several years, due to the improvement in neoadjuvant chemotherapy (NACT) prescription. One of the most controversial questions regarding indication for adjuvant RT is whether or not RT is essential in patients with early stage disease at diagnosis. The value of adjuvant RT remains highly debatable in those patients with clinically negative nodes at the completion of NACT...

INTRODUCTION: Triple-negative breast cancers (TNBC) are associated with a poor prognosis owing to an aggressive phenotype. We aimed to carry out a prospective study comparing management strategies and response to therapy in TNBC and non-TNBC patients. METHODS: Data were obtained from a prospectively maintained database of patients treated for breast cancer. RESULTS: A total of 142 TNBC and 142 age-, stage- and NPI-matched non-TNBC patients were treated...

Predictors of response to neoadjuvant chemotherapy are not available for gastric and oesophago-gastric junction carcinoma. HER-2 over-expression in breast cancer correlates with poor prognosis and high incidence of recurrence. First aim of this study was to evaluate if the HER-2 expression/amplification is predictive of response to neoadjuvant chemotherapy in terms of pathologic regression. Secondary aim was to evaluate if HER-2 expression varies after neoadjuvant treatment. Thirty-five patients with locally advanced gastric or oesophago-gastric junction carcinoma underwent preoperative chemotherapy and surgical resection at San Raffaele Scientific Institute and Spedali Civili of Brescia...

Estrogen receptor positive (ER(+)) breast cancer (BC) is highly hormonal therapy-responsive. The choice between neoadjuvant hormonal therapy (NHT) and neoadjuvant chemotherapy (NCT) remains controversial. The aim of this meta-analysis was to evaluate benefits and safety of NHT compared with NCT for operable BC patients. Areas covered: Electronic databases were searched to identify randomized clinical trials (RCTs) comparing NHT and NCT for treatment of invasive and immunohistochemically ER(+) BC. Major outcomes were clinical response rate, pathologic complete response (pCR), operation methods, recurrence, and adverse events...

We characterize novel breast cancer imaging biomarkers for monitoring neoadjuvant chemotherapy (NACT) and predicting outcome. Specifically, we recruited 30 patients for a pilot study in which NACT patients were imaged using dynamic tomographic optical breast imaging (DTOBI) to quantify the hemodynamic changes due to partial mammographic compression. DTOBI scans were obtained pre-treatment (referred to as day 0), as well as 7 and 30 days into therapy on female patients undergoing NACT. We present data for the 13 patients who participated in both day 0 and 7 measurements and had evaluable data, of which 7 also returned for day 30 measurements...

PURPOSE: Due to inherent disease heterogeneity, targeted therapies have eluded TNBC, and biomarkers predictive of treatment response have not yet been identified. This study was designed to determine if the mTOR inhibitor everolimus with cisplatin and paclitaxel would provide synergistic anti-tumor effects in TNBC. EXPERIMENTAL DESIGN: Stage II/III patients with TNBC were enrolled in a randomized phase II trial of preoperative weekly cisplatin, paclitaxel and daily everolimus or placebo for 12 weeks, until definitive surgery...

BACKGROUND: Extensive studies have confirmed the efficacy of taxanes in combination with anthracycline-based chemotherapy on breast cancer. However, few studies have assessed the efficacy of weekly taxane-anthracycline regimens on locally advanced breast cancer. This study was to compare the efficacy and safety of a weekly taxane-anthracycline regimen with those of tri-weekly anthracycline-based regimen in patients with locally advanced breast cancer. METHODS: Patients with locally advanced breast cancer were randomized to receive 4-6 cycles of neoadjuvant chemotherapy with tri-weekly 5-fluorouracil-epirubicin-cyclophosphamide (FEC) regimen or weekly paclitaxel-epirubicin (PE) regimen...
