Abstract BACKGROUND: A survey of breast surgeons was conducted to evaluate changes in clinical practice regarding sentinel node biopsy (SNB) among clinically node-negative patients after neoadjuvant chemotherapy for breast cancer with axillary node metastasis. METHODS: We conducted two surveys among 252 members of the Korean Breast Cancer Society. The questionnaire comprised a case presentation and two associated questions. The case outlined a woman diagnosed with right breast cancer; core needle biopsy had confirmed invasive ductal carcinoma and tumor size was 4 cm on imaging examination. Fine needle as...

DiscussionUse of AUS may help to tailor patient care without leading to overutilization of ALND, as long as neoadjuvant chemotherapy is administered when appropriate.

In this study, we report the preliminary experience and clinical outcome of robotic assisted quadrantectomy (RAQ) and immediate partial breast reconstruction (IPBR) with RLDFH. Patient concern: Decreasing and avoid back scar length after latissimus dorsi flap harvest. Diagnoses: One 28 years old female with left breast cancer underwent RAQ and IPBR with RLDFH. Initially, she was diagnosed with left breast infiltrating carcinoma that was clinical stage T3N1M0 and triple negative. Interventions: Neoadjuvant chemotherapy consisting of 4 cycles of epirubicin and cyclophosphamide followed by 4 cycles of docetaxel was...

This study was designed to present the secondary imaging endpoints of the trial for evaluating mammogram (MMG), ultrasound (US) and image guided biopsy (IGBx) assessment of pathologic complete response (pCR) in breast cancer (BC) patients undergoing neoadjuvant chemotherapy (NAC). METHODS: Patients with T1-3, N0-3, M0 triple-negative or HER2-positive BC who received NAC were enrolled in an Institutional Review Board-approved prospective, clinical trial. Patients underwent US and MMG at baseline and after NAC. Images were evaluated for residual abnormality and to determine modality for IGBx [US-guided (USG) or ste...

Abstract BACKGROUND: Regulatory T cells(Tregs) and myeloid-derived suppressor cells(MDSCs) represent two immunosuppressive cell populations that are important in the establishment and maintenance of cancer immune tolerance. MDSCs can express IDO and promote immune tolerance via expansion of Treg cell. METHOD: We use needle biopsy breast cancer tissues prior to neoadjuvant chemotherapy(NCT) staining for CD33, Foxp3 and IDO by immunohistochemistry to evaluate whether they were correlated with subsequent treatment responses in breast cancer. RESULTS: Expressions of IDO, CD33+MDSCs and Foxp3+Tregs were corre...

ConclusionThe presence of microcalcifications on imaging and DCIS on initial CNB are associated with residual disease after neoadjuvant chemotherapy in TNBC. These variables can aid in identifying patients with TNBC suitable for inclusion in trials evaluating non‐surgical management after neoadjuvant chemotherapy.

CONCLUSION: Neoadjuvant aromatase inhibitor therapy is an acceptable strategy in selected postmenopausal patients with ER-rich and HER2-negative early breast cancer with ductal histology and should be considered when chemotherapy either isn't indicated or feasible.

Authors: Guenther V, Alkatout I, Junkers W, Bauerschlag D, Maass N, von Otte S Abstract Many premenopausal patients who develop breast cancer have not yet completed their family planning, so measures of fertility protection to preserve their fertile potential would be beneficial. Polychemotherapy causes irreversible damage to the ovarian follicles - irrespective of whether in a neoadjuvant or adjuvant setting - and this can sometimes result in permanent infertility. Depending on which cytostatic agents are used and on the age-related ovarian reserve of the woman, gonadotoxic risk must be classified as low, moderate...
