Breast cancer is the presence of malignant breast nodule, mass or abscess.
Most common symptom of breast cancer is a new lump or mass in the
breast. The lump or mass is usually painless, hard & irregular but
it can also be tender, soft, rounded or painful.
Other signs & symptoms include breast pain or nipple pain, nipple
discharge, nipple retraction and presence of breast skin changes (eg
peau d' orange, nipple excoriation, scaling, inflammation, skin
tethering, ulceration, abscess).
The reduced incidence of breast cancer with 5-year prophylaxis with the aromatase inhibitor anastrozole among women at high risk of the disease persists even after anastrozole cessation, suggests long-term results of the IBIS-II* trial presented at SABCS 2019.
The addition of tucatinib to a trastuzumab-capecitabine regimen improved progression-free survival (PFS) in patients with HER2+ metastatic breast cancer (MBC) previously treated with multiple HER2-targeted agents, according to the HER2CLIMB* study presented at SABCS** 2019. Additionally, this improved PFS was also noted in patients with brain metastases.
The trastuzumab biosimilar HLX02 was equivalent to the reference trastuzumab in terms of overall response rate (ORR) in women with HER2*-positive (HER2+) breast cancer, along with similar safety profile, reveals a study presented at ESMO Asia 2019.
The addition of pertuzumab to a trastuzumab-docetaxel regimen in the neoadjuvant setting improved total pathological complete response (tpCR) rates in Asian women with early or locally advanced ERBB2-positive breast cancer, according to the phase III PEONY trial from China.
A combination of the CDK 4/6 inhibitor abemaciclib with fulvestrant improved overall survival (OS) in patients with HR+, HER2- advanced breast cancer (ABC), with a trend toward improved outcomes in patients with poor prognosis, according to results of the phase III MONARCH 2* trial presented at ESMO 2019.
Use of menopausal hormone therapy (MHT) was associated with a significantly increased risk of invasive breast cancer, which became progressively greater with longer duration of use, a meta-analysis of worldwide prospective epidemiological studies has shown.
Patients with HER2+ breast cancer with disease progression despite ≥2 lines of HER2-directed therapy may improve their progression-free survival (PFS) with the addition of neratinib than lapatinib to capecitabine, according to the phase III NALA* trial.
Annual breast cancer screening with magnetic resonance imaging (MRI) led to detection of fewer late-stage and node-positive cancers than annual mammography, according to the FaMRIsc* study from the Netherlands. However, specificity was lower and number of false-positives higher with MRI vs mammography.
The addition of the CDK* 4/6 inhibitor ribociclib to endocrine therapy significantly extended overall survival (OS) in premenopausal women with HR+ HER2- advanced breast cancer, as evidenced in the phase III MONALEESA-7** trial.
New drug applications approved by US FDA as of 16 - 31 May 2019 which includes New Molecular Entities (NMEs) and new biologics. It does not include Tentative Approvals. Supplemental approvals may have occurred since the original approval date.
Rotavirus (RV) is highly contagious. Globally, 2 million children are hospitalized and more than 500,000 die annually from RV associated gastroenteritis. Therefore, vaccination is imperative for the prevention of RV infections.
