Intraoperative radiotherapy versus whole breast radiotherapy in early-stage breast cancer: a retrospective outcome analysis based on ASTRO guidelines on PBI.

Background: Intraoperative radiotherapy (IORT) is a convenient treatment techniques for patients with early-stage breast cancer. We aimed to compare the outcome of IORT to that of whole-breast external beam radiotherapy (EBRT) in highly selected breast cancer patients based on the 2023 American Society for Radiation Oncology (ASTRO) Clinical Practice Guideline for Partial Breast Irradiation (PBI).

Patients And Methods: We reviewed patients who underwent breast-conserving surgery (BCS) and received either IORT or EBRT for early-stage breast cancer between 2014 and 2019.

Real-world outcomes of everolimus-based treatment in a Taiwanese cohort with metastatic HR+/HER2- breast cancer.

Background: Everolimus was the first orally targeted therapy for certain cancers. It was introduced before CDK4/6 inhibitors and is widely used to treat advanced hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer. This study presents comprehensive findings including updated data and long-term survival analyses focusing on patients with HR+/HER2- metastatic breast cancer who received everolimus-based treatment.

Monitoring trends in the absolute lymphocyte count and the neutrophil-to-lymphocyte ratio in patients with breast cancer receiving eribulin.

Background: Studies have shown that the absolute lymphocyte count (ALC) and the neutrophil-to-lymphocyte ratio (NLR) are related to the outcomes in patients with breast cancer receiving specific chemotherapies. However, the reports have focussed on the initial blood test and there is a lack of evidence or data to support that dynamic changes of ALC or NLR are associated with the patients' survival outcomes.

Methods: We retrospectively reviewed electronic medical records from patients with breast cancer treated with eribulin from 2015 to 2019 at our institution.

Analysis of MUC6 polymorphisms on the clinicopathologic characteristics of Asian patients with oral squamous cell carcinoma.

Head and neck squamous cell carcinomas (HNSCCs) are generally associated with tobacco consumption, alcohol abuse or both. Mucins (MUCs) are high-molecular-weight glycoproteins produced by many epithelial tissues. Many studies have indicated that MUCs play an important role in cancer metastasis.

Robotic Versus Conventional or Endoscopic-assisted Nipple-sparing Mastectomy and Immediate Prosthesis Breast Reconstruction in the Management of Breast Cancer: A Prospectively Designed Multicenter Trial Comparing Clinical Outcomes, Medical Cost, and Patient-reported Outcomes (RCENSM-P).

Objective: To compare the clinical and patient-reported outcomes of minimal access and conventional nipple-sparing mastectomy (C-NSM). The secondary outcomes investigated included medical costs and oncological safety.

Background: Minimal-access NSM has been increasingly applied in the treatment of patients with breast cancer.

Effects of hepatocyte growth factor on porcine mammary cell growth and senescence.

Background: The porcine mammary glands share morphological and physiological similarities with human ones, making primary porcine mammary cells (PMC) suitable for biomedical research and a potential cellular therapeutic for breast cancer xenogeneic cell immunotherapy. Primary cells isolated from tissues remain the physiological functions of origin tissues but their self-renewal ability is restricted and cells acquire senescence during in vitro expansion. To overcome these drawbacks, here we sought to establish an approach to efficiently increase PMC's in vitro growth.

Osteoprogenitor-GMP crosstalk underpins solid tumor-induced systemic immunosuppression and persists after tumor removal.

Remote tumors disrupt the bone marrow (BM) ecosystem (BME), eliciting the overproduction of BM-derived immunosuppressive cells. However, the underlying mechanisms remain poorly understood. Herein, we characterized breast and lung cancer-induced BME shifts pre- and post-tumor removal.

Quality of care in the course of subcutaneous versus intravenous trastuzumab administration in patients with breast cancer: an integrated time-motion study with mixed-methods research.

Objectives: This study aimed to compare the time required and concerns raised by various perspectives of participants regarding administering subcutaneous and intravenous trastuzumab for patients with breast cancer (BC).

Design: This observational time-motion study design with mixed-methods research (cross-sectional surveys and semistructured interviews) was conducted. The time spent on preparing or administering trastuzumab by different healthcare professionals (HCPs) was recorded.

Comparison of Quality of Life Between Breast Cancer Patients Treated With and Without Adjunctive Traditional Chinese Medicine in Taiwan.

In Taiwan, breast cancer has the highest incidence among all cancers. Although adjunctive traditional Chinese medicine treatment (TCM) have been used to ameliorate the side effects or discomfort caused by cancer treatments, no study has focused on the assessment of the quality of life of patients undergoing adjunctive TCM treatments. This study compared the quality of life between breast cancer patients treated with and without adjunctive TCM.

Comparing Genetic Risk and Clinical Risk Classification in Luminal-like Breast Cancer Patients Using a 23-Gene Classifier.

Background: A 23-gene classifier has been developed based on gene expression profiles of Taiwanese luminal-like breast cancer. We aim to stratify risk of relapse and identify patients who may benefit from adjuvant chemotherapy based on genetic model among distinct clinical risk groups. Methods: There were 248 luminal (hormone receptor-positive and human epidermal growth factor receptor II-negative) breast cancer patients with 23-gene classifier results.

Short-term effect of internet-delivered mindfulness-based stress reduction on mental health, self-efficacy, and body image among women with breast cancer during the COVID-19 pandemic.

Background And Aim: During the COVID-19 pandemic, an Internet-Mindfulness-Based Stress Reduction (iMBSR) program was delivered and may be better than an in-person approach. Our study evaluated the effects of iMBSR intervention on mental health, self-efficacy, and body image in women with breast cancer in Taiwan.

Materials And Methods: Sixty-seven women with breast cancer were allocated to a 6-week iMBSR ( = 41) program or a waitlist control group ( = 26), without heterogeneity between group characteristics.

Feature generation and contribution comparison for electronic fraud detection.

Modern money transfer services are convenient, attracting fraudulent actors to run scams in which victims are deceived into transferring funds to fraudulent accounts. Machine learning models are broadly applied due to the poor fraud detection performance of traditional rule-based approaches. Learning directly from raw transaction data is impractical due to its high-dimensional nature; most studies construct features instead by extracting patterns from raw transaction data.

Analysis of Genetic Variants on the Clinicopathologic Characteristics of Patients with Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the leading malignancy associated with cancer-related deaths worldwide. Many studies have indicated that mucin (MUC) expression plays an important role in cancer metastasis and recurrence. expression is observed in gastric and oncocytic phenotypes and may play an important role during cancer progression.

Does the Timing of Eribulin Treatment for Advanced or Metastatic Breast Cancer Matter? Evidence from a Real-World Setting.

Background: This study aimed to examine the effectiveness and safety of eribulin used as an early-line (EL, i.e., first-/second-line) versus late-line (LL, i.

Intratumoral xenogeneic tissue-specific cell immunotherapy inhibits tumor growth by increasing antitumor immunity in murine triple negative breast and pancreatic tumor models.

Low immunogenicity in tumors and the immunosuppressive tumor microenvironment (TME) represent major obstacles to the full success of immunotherapy in cancer patients. A novel intratumoral xenogeneic tissue-specific cell immunotherapeutic approach could overcome the obstacles. Murine 4T1 triple negative breast cancer (TNBC) cells and Pan18 pancreatic ductal adenocarcinoma (PDAC) cells were used for establishing syngeneic graft tumor models to evaluate antitumor effect of intratumoral injection of xenogeneic tissue-specific cells.

Analysis of EZH2 Genetic Variants on Triple-Negative Breast Cancer Susceptibility and Pathology.

Triple-negative breast cancer (TNBC) is the third most common female cancer in Taiwan. EZH2 plays an important role in cancer development through transcriptional repression by chromatin remodeling. However, the expression of EZH2 in breast cancer is highly correlated with tumorigenesis, and patient survival is not matched to TNBC.

Neoadjuvant afatinib with paclitaxel for triple-negative breast cancer and the molecular characteristics in responders and non-responders.

Background: The prognosis of triple-negative breast cancer (TNBC) is worse and a major proportion of TNBC expresses epidermal growth factor receptor (EGFR). Afatinib can inhibit EGFR signal pathway; however, its treatment effect for TNBC is unknown. Thus, we aimed to assess the efficacy and biomarkers of afatinib in combination with paclitaxel in a neoadjuvant setting.

Effectiveness of Fucoidan on Supplemental Therapy in Cancer Patients: A Systematic Review.

Purpose: Fucoidan is a dietary supplement which is commonly used by cancer patients. However, despite evidence of positive effects in cell culture environments, there are currently no clinical guidelines for supplementary use of fucoidan in cancer patients. This study aims to evaluate the effectiveness of fucoidan supplemental use.

Impact of BRCA mutation on the survival and risk of contralateral breast cancer in Asian breast cancer patients.

Purpose: Breast cancer is increasing around the globe, including Asia. We aimed to examine the survival and risk of contralateral breast cancer (CBC) in Asian breast cancer patients with BRCA mutations.

Methods: A total of 128 breast cancer patients with germline BRCA mutations and 4,754 control breast cancer patients were enrolled.

miR-4759 suppresses breast cancer through immune checkpoint blockade.

Programmed cell death protein 1 (PD-1)/ programmed cell death protein ligand 1 (PD-L1) is the key immune checkpoint governing evasion of advanced cancer from immune surveillance. Immuno-oncology (IO) therapy targeting PD-1/PD-L1 with traditional antibodies is a promising approach to multiple cancer types but to which the response rate remains moderate in breast cancer, calling for the need of exploring alternative IO targeting approaches. A miRNA-gene network was integrated by a bioinformatics approach and corroborated with The Cancer Genome Atlas (TCGA) to screen miRNAs regulating immune checkpoint genes and associated with patient survival.

Correlation of ER, PR, and HER2 at the protein and mRNA levels in Asian patients with operable breast cancer.

Breast cancer is the most common cancer and the leading cause of cancer-related deaths in women. The estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) are the important biomarkers in the prognosis of breast cancer, and their expression is used to categorize breast cancer into subtypes. We aimed to analyze the concordance among ER, PR, and HER2 expression levels and breast cancer subtyping results obtained by immunohistochemistry (IHC, for protein) and reverse transcriptase-polymerase chain reaction (RT-PCR, for mRNA) and to assess the recurrence-free survival (RFS) of the different subtypes as determined by the two methods.

ERα determines the chemo-resistant function of mutant p53 involving the switch between lincRNA-p21 and DDB2 expressions.

Mutant p53 (mutp53) commonly loses its DNA binding affinity to p53 response elements (p53REs) and fails to induce apoptosis fully. However, the p53 mutation does not predict chemoresistance in all subtypes of breast cancers, and the critical determinants remain to be identified. In this study, mutp53 was found to mediate chemotherapy-induced long intergenic noncoding RNA-p21 (lincRNA-p21) expression by targeting the G-quadruplex structure rather than the p53RE on its promoter to promote chemosensitivity.

Evading immune surveillance via tyrosine phosphorylation of nuclear PCNA.

Increased DNA replication and metastasis are hallmarks of cancer progression, while deregulated proliferation often triggers sustained replication stresses in cancer cells. How cancer cells overcome the growth stress and proceed to metastasis remains largely elusive. Proliferating cell nuclear antigen (PCNA) is an indispensable component of the DNA replication machinery.
