Importance: Preferred neoadjuvant strategies for early or locally advanced triple-negative breast cancer include a 4-drug chemotherapy regimen containing anthracyclines, cyclophosphamide, taxanes, and platinum. Blockade of the programmed death receptor 1/ligand-1 (PD-1/PD-L1) pathway may improve efficacy of classic neoadjuvant chemotherapy. Camrelizumab, an anti-PD-1 antibody, has showed antitumor activity in advanced triple-negative breast cancer.

Methods: This study included 141 patients diagnosed with invasive breast cancer from two centers (center 1: n = 101, center 2: n = 40). Patients from center 1 were randomly divided into training set and test set 1.
Purpose: Results from studies of extended capecitabine after the standard adjuvant chemotherapy in early stage triple-negative breast cancer (TNBC) were inconsistent, and only low-dose capecitabine from the SYSUCC-001 trial improved disease-free survival (DFS). Adjustment of the conventional adjuvant chemotherapy doses affect the prognosis and may affect the efficacy of subsequent treatments. This study investigated whether the survival benefit of the SYSUCC-001 trial was affected by dose adjustment of the standard adjuvant chemotherapy or not.

The aim of this study was to evaluate the screening results and explore the influencing factors of breast cancer detection rate in Guangdong.
Methods: This cross-sectional study was conducted among 2,024,960 women aged 35-64 in Guangdong Province during 2017-2021.
The 2021 National Comprehensive Cancer Network guidelines recommend that adjuvant chemotherapy combined with trastuzumab be considered for human epidermal growth factor receptor 2 (HER-2)-positive breast cancer patients with small tumors (tumor diameter ≤1 cm) and negative lymph nodes. Additionally, the prognostic factors and clinical significance of HER-2-positive breast cancer with negative lymph nodes and a tumor diameter ≤1 cm remain unclear. In the present study, the clinical data and prognostic factors of 87 patients with HER-2-positive breast cancer with negative lymph nodes and a tumor diameter ≤1 cm admitted to Guangdong Women and Children Hospital from January 2013 to December 2019 were retrospectively analyzed.

Methods: Breast cancer (BRCA) samples with ATIRE profiles from The Cancer Genome Atlas were divided into training (n = 452) and internal validation cohorts (n = 311), and 197 additional BRCA patients were recruited as an external validation cohort.
Importance: Among all subtypes of breast cancer, triple-negative breast cancer has a relatively high relapse rate and poor outcome after standard treatment. Effective strategies to reduce the risk of relapse and death are needed.
Objective: To evaluate the efficacy and adverse effects of low-dose capecitabine maintenance after standard adjuvant chemotherapy in early-stage triple-negative breast cancer.
Postoperative bleeding is the most frequent serious complications after vacuum-assisted breast biopsy (VABB). The aim of this study was to evaluate the clinical effect of using urinary balloon catheter to prevent postoperative bleeding after ultrasound-guided VABB. From May 2016 to June 2018, 324 patients who underwent ultrasound-guided VABB were randomized into the study group and control group.

Some women treated for DCIS subsequently develop invasive breast cancer. DCIS with microinvasion is considered as the interim stage in the progression from DCIS to invasive breast cancer.

Furthermore, immune cell accumulation in breast tumor types has been observed, particularly distributed in regions surrounding the bacteria. M2 macrophages are associated with breast cancer aggressiveness, whereas M1 macrophages are prone to devouring bacteria and killing cancer cells.

Adjuvant endocrine therapy is widely used for hormone receptor-positive (HR+) early-stage breast cancer (EBC), and evidence suggests that aromatase inhibitors (AIs) may improve QoL for these patients. This study evaluated QoL in postmenopausal Chinese patients with HR+ EBC taking AIs.

Yet, there is still limited information concerning the molecular mechanisms. Analysis of transcriptomic profiles in TDLUs may provide insight into early breast tumorigenesis.

The exposure of HSPs containing tumour peptide complex to immune surveillance elements may elicit a specific anti-tumour response. The present study examined the potential of anticancer drugs to induce apoptosis of HepG2 cells and elicit the expression of HSP proteins, including HSP70 and gp96, on the membrane or their release to the extracellular environment, leading to HSP exposure.

This study investigated the relationships between ductoscopic image-based indicators and breast cancer risk, and developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge. A total of 879 consecutive inpatients (916 breasts) with nipple discharge who underwent selective duct excision for intraductal neoplasms detected by MD from June 2008 to April 2014 were analyzed retrospectively.

Objectives: To study the etiology, clinical and pathologic characteristics of periductal mastitis with fistula and estimate the effect of anti-mycobacterial agents for periductal mastitis with fistula.
Methods: Totally 27 patients of periductal mastitis with fistula received anti-mycobacteria drugs therapy from December 2008 to September 2011 were analyzed retrospectively. All of the patients were female.
To screen candidate methylation markers for early detection of breast cancer and to explore the relationship between methylation and gene expression, we performed methylated-CpG island recovery assay (MIRA) combined with CpG island array on 61982 CpG sites across 4162 genes in 10 cancerous and 10 non-cancerous breast tissues. Direct bisulfite sequencing and combined bisulfite restriction analysis (COBRA) were carried out in independent cancerous and non-cancerous samples. Gene expression was analyzed by microarrays and validated using RT-PCR.
