BACKGROUND: Sentinel lymph node (SLN) resection is imperative for breast cancer staging. Axillary reverse mapping (ARM) can preserve arm draining nodes and lymphatics during surgery. ARM is generally performed with isosulfan blue (ISB), restricting its use for concurrent SLN biopsy. Indocyanine green (ICG) could serve as an alternative to ISB for ARM procedures. METHODS: SLN mapping and biopsy was performed via periareolar injection of 99 technetium-sulfur colloid (99m TcSc, TSC)...

Post-chemotherapy cognitive impairment, or PCCI, is a common complaint, particularly among breast cancer patients. However, the exact nature of PCCI appears complex. To model the human condition, ovariectomized C57BL/6J mice were treated iv weekly for 4 weeks with saline, 2 mg/kg doxorubicin (DOX), 50 mg/kg cyclophosphamide (CYP), or DOX+CYP. For the subsequent 10 weeks, mice were assessed on several behavioral tests, including those measuring spatial learning and memory. After sacrifice, hippocampal spine density and morphology in the dentate gyrus, CA1, and CA3 regions were measured...

Background: Pathological complete response (pCR) is associated with improved prognosis in triple-negative breast cancer (TNBC). The optimal chemotherapy regimen is unclear. Weekly nab-paclitaxel vs conventional paclitaxel or addition of carboplatin to anthracycline-taxane results in higher pCR rates with uncertain survival impact. We evaluated carboplatin vs gemcitabine with a nab-paclitaxel backbone as a short 12-week A-free regimen with a focus on early response. Methods: Patients with TNBC (estrogen receptor/progesterone receptor < 1%, human epidermal growth factor receptor 2-negative, cT1c-cT4c, cN0/+) were randomly assigned to A: nab-paclitaxel 125 mg/m2/gemcitabine 1000 mg/m2 d1,8 three times weekly (q3w); vs B: nab-paclitaxel 125 mg/m2/carboplatin AUC2 day 1,8 q3w...

Progestin and AdipoQ Receptor 4 (PAQR4) is a member of the PAQR family and the members within this family are involved in the regulation of a number of biological processes including metabolism and cancer development. The potential function of PAQR4 in human cancers is unknown. Analysis of ONCOMINE database reveals that PAQR4 is highly expressed in human breast cancers. We confirmed this finding by analyzing 82 human breast cancers samples. PAQR4 mRNA level was robustly upregulated in human breast cancer samples compared with their corresponding para-cancerous histological normal tissues (P < 0...

Motivation: Long non-coding RNAs (lncRNAs) play crucial roles in complex disease diagnosis, prognosis, prevention, and treatment, but only a small portion of lncRNA-disease associations have been experimentally verified. Various computational models have been proposed to identify lncRNA-disease associations by integrating heterogeneous data sources. However, existing models generally ignore the intrinsic structure of data sources or treat them as equally relevant, while they may not be...

BACKGROUND: Granulocyte colony-stimulating factors (G-CSFs) are widely used to prevent neutropenia in cancer patients undergoing myelosuppressive chemotherapy. Several biosimilar medicines of G-CSF are now available, with their development involving a step-wise series of comparisons to demonstrate similarity to reference biologics. Randomised clinical trials (RCTs) are considered confirmatory, and for G-CSF biosimilars, patients with breast cancer (BC) undergoing myelosuppressive chemotherapy are the most sensitive population in which to confirm similarity...

AIM: To determine the value of mammography and breast ultrasound (US) in predicting outcomes in HER2 positive breast cancer patients (pts) within Neo-ALTTO trial. PATIENTS AND METHODS: Mammography and US were required at baseline, week 6 and surgery. Two independent blinded investigators reviewed the measurements and assigned the corresponding response category. Pts showing complete or partial response according to RECIST (v1.1) were classified as responders. The association between imaging response at week 6 or prior to surgery was evaluated with respect to pathological complete response (pCR) and event-free Survival (EFS)...

The anticancer properties of ursolic acid (UA) and metformin (Met) have been well demonstrated. However, whether these compounds can act synergistically to prevent and treat cancer is not known. We present in this study, the synergism between UA and Met, and that of a new codrug made of UA and Met (UA-Met) against several cancer cell lines. The combination of high concentration of UA (25, 50, 75, 100 μM) and Met (5, 10, 20, 40 mM) resulted in synergetic cytotoxicity on MDA-MB-231 and MCF-7 cells (CI < 0...

Quinazolinone-based anti-cancer agents were designed, decorated with functional groups from a 2-methoxyestradiol-based microtubule disruptor series, incorporating the aryl sulfamate motif of steroid sulfatase (STS) inhibitors. The steroidal AB-ring system was mimicked, favoring conformations with an N-2 substituent occupying D-ring space. Evaluation against breast and prostate tumor cell lines identified 7b with DU-145 anti-proliferative activity (GI50 300 nM). A preliminary structure-activity relationship afforded compounds (e...

Caspase-3 is a proteolytic enzyme that functions as a key effector in apoptotic cell death. Determining activity of caspase-3 provides critical information about cancer cell viability and response to treatment. To measure apoptosis in intact cells and living mice, a fluorescence imaging reporter that detects caspase-3 activity by Förster resonance energy transfer (FRET) was used. Changes in FRET by fluorescence lifetime imaging microscopy (FLIM) were measured. Unlike FRET measurements based on fluorescence intensity, lifetime measurements are independent of reporter concentration and scattering of light in tissue, making FLIM a robust method for imaging in 3D environments...
