Background: Limited function of the upper limb is the main problem after radical therapy of breast cancer. The shoulder joint is most commonly affected. However, even the simplest movements involve entire muscle groups. The aim of this study was to assess elbow flexor and extensor function in women following treatment of breast cancer.
Material And Methods: 47 women at a mean age of 62 years (range 45 - 77 years) post Patey mastectomy participated in the study. The function of muscles of the elbow joint (peak torque, work, power) was examined by isokinetic testing.
Results: Statistically significant differences were revealed in the group of 47 women between the dominant vs. non-dominant side of the body. Weakness of the elbow extensors and flexors on the operated side was revealed in subgroup analysis. Decreased force and velocity parameters of elbow flexors and extensors were noted in women with cancer on the dominant (right) side (subgroup 1) and the differences between body sides were no longer statistically significant. However, in women with cancer on the non-dominant side (subgroup 2), the discrepancy between the limbs increased and was statistically significant. Mean differences were not statistically significant only with respect to peak torque of the elbow extensors.
Conclusions: Treatment of breast cancer causes not only weakness of shoulder muscles but also of elbow-moving muscles. Treatment of cancer of the left breast can lead to false positive (too high), and treatment of cancer of the left breast, false negative (too low) functional impairment of the elbow extensors and flexors.

This study presents T-1-NBAB, a new compound derived from the natural xanthine alkaloid theobromine, aimed at inhibiting VEGFR-2, a crucial protein in angiogenesis. T-1-NBAB's potential to interacts with and inhibit the VEGFR-2 was indicated using in silico techniques like molecular docking, MD simulations, MM-GBSA, PLIP, essential dynamics, and bi-dimensional projection experiments. DFT experiments was utilized also to study the structural and electrostatic properties of T-1-NBAB.

Oral selective estrogen receptor degraders (SERDs) are pure estrogen receptor antagonists that have the potential to overcome common resistance mechanisms to endocrine therapy in estrogen receptor-positive breast cancer. There are currently five oral SERDs in published and ongoing clinical trials-elacestrant, camizestrant, giredestrant, imlunestrant, and amcenestrant-with more in development. They offer a reasonably well-tolerated oral therapy option with low discontinuation rates in studies.

Purpose: Receptor CUB-domain containing- protein 1 (CDCP1) was evaluated as a target for detection and treatment of breast cancer.
Experimental Design: CDCP1 expression was assessed immunohistochemically in tumors from 423 patients (119 triple-negative breast cancer (TNBC); 75 HER2+; 229 ER+/HER2- including 228 primary tumors, 229 lymph node and 47 distant metastases). Cell cytotoxicity induced in vitro by a CDCP1-targeting antibody-drug conjugate (ADC), consisting of the human/mouse chimeric antibody ch10D7 and the microtubule disruptor monomethyl auristatin E (MMAE), was quantified, including in combination with HER2-targeting ADC T-DM1.

Background: Race/ethnicity may affect outcomes in metastatic breast cancer (MBC) due to biological and social determinants. We evaluated the impact of race/ethnicity on clinical, socioeconomic, and genomic characteristics, clinical trial participation, and receipt of genotype-matched therapy among patients with MBC.
Methods: A retrospective study of patients with MBC who underwent cell-free DNA testing (cfDNA, Guardant360â, 74 gene panel) between 11/2016 and 11/2020 was conducted.

The word "cancer" evokes myriad emotions, ranging from fear and despair to hope and determination. Cancer is aptly defined as a complex and multifaceted group of diseases that has unapologetically led to the loss of countless lives and affected innumerable families across the globe. The battle with cancer is not only a physical battle, but also an emotional, as well as a psychological skirmish for patients and for their loved ones.
