BACKGROUND: A few retrospective studies have indicated that neoadjuvant chemotherapy (NAC) in breast cancer may change biomarker profiles of the primary tumor. Little is known about the status of HER-2 gene of the synchronous nodal metastases when that of the residual tumor undergoes negative conversion in a neoadjuvant setting. CASE PRESENTATION: We describe a female patient with left breast cancer (T2N2M0) who underwent negative conversion of HER-2 in the primary tumor instead of the synchronous nodal lesions after NAC...

It is well known that BRCA1 and BRCA2 play a central role in DNA repair, but the relationship between BRCA1 and BRCA2 mRNA expression and response to neoadjuvant chemotherapy in sporadic breast cancer patients has not been well established. Here, we investigate the association between BRCA1 or BRCA2 mRNA expression levels and pathological response in 674 BRCA1/2 mutation-negative breast cancer patients who received neoadjuvant chemotherapy. BRCA1and BRCA2 mRNA expression were assessed using quantitative real-time polymerase chain reaction in core biopsy breast cancer tissue obtained prior to the initiation of neoadjuvant chemotherapy...

Background: The presence of stromal tumor-infiltrating lymphocytes (TILs) is associated with increased pathological complete response (pCR) and improved outcomes in HER2-positive early breast cancer (BC) treated with anti-HER2-based chemotherapy. In the absence of chemotherapy, the association of TILs with pCR following anti-HER2 therapy-only is largely unknown. Patients and methods: The PAMELA neoadjuvant trial treated 151 women with HER2-positive BC with lapatinib and trastuzumab (and hormonal therapy if hormone receptor [HR]-positive) for 18 weeks...

The use of neoadjuvant systemic therapy in the treatment of breast cancer patients is increasing beyond the scope of locally advanced disease. Imaging provides important information in assessing response to therapy as a complement to conventional tumor measurements via physical examination. The purpose of this article is to discuss the advantages and limitations of current assessment methods, as well as review functional and molecular imaging approaches being investigated as emerging techniques for evaluating neoadjuvant therapy response for patients with primary breast cancer...

BACKGROUND: In patients with breast cancer who are candidates for neoadjuvant therapy (NAT), the timing of when to perform sentinel lymph node biopsy (SLNB) remains under discussion. The aim of this study was to compare the advantages and disadvantages of SLNB performed before and after NAT. PATIENTS AND METHODS: One hundred seventy-two patients, T1c to T3 and N0 (clinically and according to ultrasound) candidates for NAT were included. We compared the outcomes of 2 groups: (1) 122 patients of whom SLNB was performed before NAT (pre-NAT) from December 2006 to April 2014; and (2) 50 patients with SLNB performed after NAT (post-NAT) from May 2014 to July 2016...

Inflammatory breast cancer (IBC) is a very aggressive form of breast cancer, as compared to locally advanced breast cancer (LABC). Neoadjuvant chemotherapy followed by surgery is the standard treatment in both cases. Whether IBC is less chemosensitive than LABC remains unclear. We retrospectively compared the rate of pathological complete response (pCR) to neoadjuvant chemotherapy in IBC and LABC. METHODS: Patients with IBC or LABC treated with neoadjuvant anthracycline-based chemotherapy followed by surgery were selected from our institutional database...

BACKGROUND: Chemotherapy-induced neutropenia (CIN) can result in poor tolerance of chemotherapy, leading to dose reductions, delays in therapy schedules, morbidity and mortality. Actively identifying predisposing risk factors before treatment is of paramount importance. We hypothesised that chemotherapy is associated with a greater increase in CIN and its complications in HIV-infected patients than in those who are not infected. OBJECTIVE: To establish the incidence of CIN in HIV-infected and uninfected patients undergoing chemotherapy...

Morphological evaluation of tumor-infiltrating lymphocytes (TILs) in breast cancer is gaining momentum as evidence strengthens the clinical relevance of this immunological biomarker. TILs in the post-neoadjuvant residual disease setting are acquiring increasing importance as a stratifying marker in clinical trials, considering the raising interest on immunotherapeutic strategies after neoadjuvant chemotherapy. TILs in ductal carcinoma in situ, with or without invasive carcinoma, represent an emerging area of clinical breast cancer research...

Neoadjuvant therapy has become increasingly common in human epidermal growth factor receptor-2 (HER2)-positive breast cancer. In this study, we examined the impact of different clinicopathological characteristics on pathological complete response (pCR) in patients treated with anti-HER2 agents. The PubMed and Embase databases were searched from inception through April 2017 to identify studies that met pre-specified criteria. The odds ratios (ORs) and 95% confidence intervals (CIs) were extracted directly or were calculated with other available information...

Proper organization of the mitotic spindle is key to genetic stability, but molecular components of inter-microtubule bridges that crosslink kinetochore fibers (K-fibers) are still largely unknown. Here we identify a kinase-independent function of class II phosphoinositide 3-OH kinase α (PI3K-C2α) acting as limiting scaffold protein organizing clathrin and TACC3 complex crosslinking K-fibers. Downregulation of PI3K-C2α causes spindle alterations, delayed anaphase onset, and aneuploidy, indicating that PI3K-C2α expression is required for genomic stability...

BACKGROUND: Surgery for the primary tumor in metastatic breast cancer is usually not recommended, assuming that local therapy provides no advantage. Recent reports suggest a survival improvement after locoregional treatment, but this is still controversial. We aimed to evaluate the effectiveness of locoregional treatment in primary metastatic breast cancer and to determine associated factors. METHODS: A retrospective analysis of 39 women with de novo metastatic breast cancer at Hospital Universitario La Paz, from January-2012 to June-2016 grouped by locoregional treatment (n=23) or not (n=16)...

John Boyages
Radiation therapy (RT) is an important component of breast cancer treatment. RT reduces local recurrence and breast cancer mortality after breast conservation for all patients and for node-positive patients after a mastectomy. Short courses of RT over 3-4 weeks are generally as effective as longer courses. A patient subgroup where RT can be avoided after conservative surgery has not been consistently identified. A radiation boost reduces the risk of a recurrence in the breast but may be omitted for older patients with good prognosis tumours with clear margins...

BACKGROUND: Current treatment for HER-2+ breast cancer includes chemotherapy and targeted HER-2 therapy with trastuzumab and/or pertuzumab. Evidence is lacking on the safety of breast reconstructive operations in these patients. We hypothesized that targeted HER-2 therapy was not associated with post-mastectomy reconstructive outcomes. STUDY DESIGN: Women receiving chemotherapy and post-mastectomy reconstruction at Duke University Medical Center from 2006 to 2016 were retrospectively identified...

RATIONALE: Although rare, occult breast cancer (OBC) originates from breast tissue. Its primary lesions cannot be identified by clinical examination or imaging; therefore, the diagnosis, treatment, and prognosis remain controversial. PATIENT CONCERNS: This study comprised 5 female OBC patients who were admitted to the Affiliated Hospital of Guizhou Medical University for painless axillary lumps. DIAGNOSES: F-flurodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) indicated metastasis in the ipsilateral axillary lymph nodes...
