ASCO: Long-Term Tamoxifen Benefit for Breast Cancer Confirmed

Women diagnosed with estrogen-receptor (ER)-positive breast cancer who took tamoxifen for 10 years as adjuvant therapy had lower risk of late recurrence and lower risk of death compared to those who took the drug for 5 years. These results corroborate the findings of the international ATLAS trial.

Conclusion: Breast MRI is an useful tool for the locoregional staging of breast cancer, because it provides useful information that can have a positive impact on patient treatment.Resumo Objetivo: Avaliar o impacto do uso da resson ância magnética (RM) no estadiamento pré-operatório do câncer de mama. Materiais e Métodos: Foram avaliadas 61 pacientes com carcinoma mamário submetidas a RM das mamas, no período de agosto de 2015 a abril de 2016. Um mastologista foi questionado sobre a conduta terapêutica indicada diant e dos dados da paciente e dos exames convencion...

We sought to determine the underlying mechanism of therapeutic response. Response to 17b-estradiol was assessed in ER+ breast cancer models with resistance to estrogen deprivation: WHIM16 patient-derived xenografts, C7-2-HI and C4-HI murine mammary adenocarcinomas, and long-term estrogen-deprived MCF-7 cells.

Publication date: 1 October 2019Source: Life Sciences, Volume 234Author(s): Mohamed M. Fathy, Heba M. Fahmy, Omnia A. Saad, Wael M. ElshemeyAbstractAimsConventional radiotherapy is mainly restricted by the low radiation absorption efficiency of tumors tissues and the hypoxic tumor cells radio-resistance. In this paper, novel nano-radiosensitizers, magnetic nanoparticles core coated with silica, were successfully prepared to overcome these limitations.Main methodsThe prepared nanoparticles have been characterized by transmission electron microscope (TEM), Dynamic light scattering (DLS), atomic force microscope (AFM) and vib...

Aslam FarooqAbstractAu-TiO2 nanoparticles conjugated with doxorubicin (DOX) were synthesized for new photodynamic therapy (PDT) plans and for comprehensive and reliable treatment of breast cancer-related acute diseases. The anatase/rutile phase junction effect combined with plasmonic resonance is amplified in Au- TiO2 conjugated with DOX, leading to a synergistic response of PDT. ...
