AI Article Synopsis
- The study investigates how neoadjuvant therapy affects hormone receptor status (estrogen and progesterone receptors) and c-erbB2 expression in breast cancer patients.
- A total of 53 patients were analyzed, comparing the expression levels of these markers in both biopsy samples and surgical specimens, particularly in those who underwent preoperative treatment.
- Significant differences were observed in hormone receptor expression between patients who received neoadjuvant therapy and those who did not, with minor changes in receptor status post-treatment, though these changes were not statistically significant.
Article Abstract
Introduction: Pre and post-operative oncological therapy in patients with breast cancer is determined, amongst other factors, by hormone receptor status and by c-erbB2 expression. The aim of this study is to determine the influence of neoadjuvant therapy on the expression of oestrogen receptor (OR), progesterone receptor (PR) and c-erbB2.
Methods: Fifty-three patients with breast cancer diagnosed by tru-cut biopsy were studied. Patients with locally advanced carcinoma (20) had preoperative treatment. All patients underwent surgical resection. Expression of OR, PR and c-erbB2 in both the tru-cut biopsy and the gross specimen was compared.
Results: We found significant differences in OR, PR expression in both biopsy and gross specimen, between the group of patients who underwent neoadjuvant treatment and the group without pre-surgical treatment. Changes in PR, OR and c-erbB2 status were found between the tru-cut biopsy and the gross specimen, in about 10 to 40% of the cases who received neoadjuvant therapy. These changes had no statistical significance.

Objective And Significance: Transforming growth factor-beta (TGF-β) plays a pivotal role in breast development by modulating tissue composition during the developmental phase. The TGFβ type II receptor (TGFβ RII) is implicated in breast cancer and represents a valuable therapeutic target. Due to the off-target side effects of many existing TGFβI/TGFβ RII inhibitors, a more targeted approach to drug discovery is necessary.

EGFR inhibitors are a class of targeted therapies utilized in the management of certain tumor kinds such as NSCLC and breast cancer. Series of 1,2,3-triazole-Schiff's base hybrids were designed, synthesized, and estimated for their antitumor effect toward breast cancer cells, MCF-7 and MDA-MB-231. The safety and selectivity of the new compounds were tested using normal cell (WI-38).

Triple-negative breast cancer (TNBC) is highly prone to early relapse and metastasis following standard treatment. CXCL8 is a key factor in tumor invasion and metastasis, but its role in TNBC prognosis and clinicopathological correlations remains poorly understood. This study investigated CXCL8 expression and its clinical significance in TNBC to develop a prognostic nomogram for guiding intensive treatment and follow-up strategies.

The aim of this study was to comparatively determine the frequency of breast cancer-related lymphedema (BCRL) by using prospective monitoring with perometer and circumferential measurements in a group of patients who underwent breast cancer surgery. We also aimed to evaluate the relationship between volume changes and functional status and quality of life (QoL) in patients with breast cancer-related subclinical lymphedema. Patients who had unilateral breast cancer surgery for breast were assessed with circumferential and perometer, respectively, for volumes at baseline, 3rd-month, 6th-month, 9th-month, and 12th-month by the same physiotherapist.
