Publication date: Available online 21 March 2019Source: European Polymer JournalAuthor(s): Aliyeh Ghamkhari, Farideh Mahmoodzadeh, Marjan Ghorbani, Hamed HamishehkarAbstractGold nanoparticles have been used for centuries in medicine for clinical procedures. In this context, gold nanorods are considered as very promising in cancer therapy. For this purpose, gold nanorods (GNRs) coated by stimuli-responsive thiol-end capped ABC triblock copolymer [poly (metacrylic acid)-block-poly (N-isopropylacrylamide)-block-poly (N,N-dimethylaminoethyl methacrylate)-SH; P(MAAc-b-NiPAAM-b-DMAEMA)-SH] for intracellular delivery of doxorubic...

ConclusionsHematologic adverse events were common in palbociclib ‐treated cancer patients. Since palbociclib produced a higher PFS rate with a low serious complication rate, it can be a promising novel target therapy drug for treating ER‐positive and HER2‐negative breast cancer.

Understanding the tumor immune microenvironment (TIME) promises to be key for optimal cancer therapy, especially in triple-negative breast cancer (TNBC). Integrating spatial resolution of immune cells with laser capture microdissection gene expression profiles, we defined distinct TIME stratification in TNBC, with implications for current therapies including immune checkpoint blockade. TNBCs with an immunoreactive microenvironment exhibited tumoral infiltration of granzyme B+CD8+ T cells (GzmB+CD8+ T cells), a type 1 IFN signature, and elevated expression of multiple immune inhibitory molecules including indoleamine 2,3-di...

In this study, pegylated (stealth) liposomes conjugated to human serum albumin (HSA) were investigated for the delivery of a model drug (calcein) to breast cancer cells. The fluorescent results showed that calcein uptake by the two breast cancer cell lines (MDA-MB-231 and MCF-7) was significantly higher with the HSA-PEG liposomes compared to the non-targeted control liposomes. Furthermore, the exposure to low-frequency ultrasound (LFUS) resulted in a statistically significant uptake of calcein compared to the uptake without ultrasound. The described drug delivery (DD) system, which involves combining the targeted liposomal...

Authors: Zhao L, Zhou S, Gustafsson JÅ Abstract Nuclear receptors (NRs) are transcription factors actively involved in many aspects of human physiology and pathology, serving as sensors of stimuli, master regulators of downstream molecular events and hubs governing complex gene regulatory networks. The importance of various members of the NR superfamily in cancer has led to substantial efforts to target them therapeutically. Notably, drugs that block the action of estrogen receptor alpha (ERα) in patients with ERα+ breast cancer or the androgen receptor (AR) in prostate cancer patients have provid...

ConclusionsThe results show that the psychological intervention group is efficient to improve emotional state and quality of life of women with breast cancer.ResumenAntecedentes/ObjetivoEl cáncer de mama provoca niveles altos de ansiedad y depresión, empeorando la calidad de vida (CV) de las pacientes. En numerosos estudios se ha visto que la terapia grupal reduce la depresión y ansiedad además de mejorar la CV. El objetivo de este estudio es analizar la efectividad de la intervención de la terapia grupal en el estado emocional y la CV de mujeres con cáncer de mama localizado al fi...

Opinion statementBisphosphonates are utilized routinely in breast cancer. In metastatic disease with bone involvement, bisphosphonates prevent or delay skeletal-related events and can improve pain control. Different agents have shown benefit compared with placebo or no treatment. While in unselected patients, comparison between zoledronic acid and pamidronate did not show a significant difference, exploratory analyses showed that in patients with osteolytic lesions or hypercalcemia, zoledronic acid is superior to pamidronate. De-escalating treatment with zoledronic acid from every 4 to every 12  weeks has been shown t...
