BACKGROUND: Pyrotinib combined with capecitabine has been approved for the treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in China. To date, the management of early-stage or locally advanced HER2-positive breast cancer in the clinic remains challenging. We conducted this trial to investigate the efficacy and safety of pyrotinib combined with capecitabine as neoadjuvant therapy (NAT) in elderly patients with HER2-positive breast cancer...

BACKGROUND: Some studies suggested that the patients included in the Z0011 trial may represent patients with ultrasound-negative axillary nodes and axillary invasion diagnosed by sentinel node (SN) biopsy. Nevertheless, the National Comprehensive Cancer Network (NCCN) guidelines recommend SN mapping if 1 or 2 suspicious lymph nodes are identified on axillary ultrasound (AU). The aim of this preliminary phase of the Multimodal Targeted Axillary Surgery (MUTAS) trial was to establish the accuracy of SN mapping in patients with axillary involvement undergoing upfront surgery...

BACKGROUND: Black thyroid is a rare incidental finding during surgery. We report the case of a patient with papillary thyroid cancer who was incidentally found to have minocycline-induced black thyroid. CASE DESCRIPTION: A 29-year-old woman presented with a left thyroid nodule and metastatic papillary thyroid cancer involving the left neck level IV lymph nodes. She had a medical history of anxiety disorder with depression, severe acne, and rosacea, and had been taking benzodiazepines, selective serotonin reuptake inhibitors, isotretinoin, and minocycline for a few years...

BACKGROUND: Split thickness skin graft (STSG) is a routine reconstructive manoeuvre, particularly after excision of cutaneous lower limb malignancies. While surgical technique is well established, evidence supporting the postoperative management of these grafts is less robust. Compression therapy after the index procedure may be an important adjunct for graft take and minimizing complications, particularly in patients susceptible to oedema from a concurrent lymph node procedure. METHODS: An initial PubMed literature search was performed using the terms "split thickness skin graft", "compression" and "oedema" yielding no results, hence a broader search was performed combining the terms "compression", "pressure" and "split thickness skin graft" providing 383 results...

BACKGROUND: Mass-like (ML) and non-mass-like (NML) are two manifestations of breast lesions on ultrasound. Contrast-enhanced ultrasound (CEUS) can make up for the limitation of B-ultrasound (US) in the observation of focal blood flow, and shear wave elastography (SWE) can supplement the hardness information of the lesion. The present study aimed to analyze the characteristic manifestations of US, CEUS, and SWE in NML and ML breast and evaluate whether the diagnostic performance of these three ultrasound techniques differs in terms of differentiating between benign and malignant breast lesions...

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) low breast cancer (BC) accounts for 30-51% of all BCs. How to precisely assess the response to neoadjuvant therapy in this heterogenous tumor is currently unanswered. With the advance in multi-omics, refining the molecular subtyping other than the current hormone receptor (HR)-based subtyping to guide the neoadjuvant therapy for HER2-low BC is potentially feasible. METHODS: The messenger RNA (mRNA), clinical, and pathological data of all HER2-low BC patients (n=368) from the Neoadjuvant I-SPY2 Trial, were retrieved...

BACKGROUND: Pancreatic cancer is a deadly cancer with a poor prognosis. In light of mounting evidence that basement membrane genes (BMGs) play a role in the development of cancer, we sought to examine the prognostic importance and role of BMGs in pancreatic ductal adenocarcinoma (PDAC) patients. METHODS: BMGs were obtained from previous top research studies. The clinical and messenger ribonucleic acid expression data were retrieved from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) data sets, respectively...

BACKGROUND: Grading based on histopathologic indicators cannot accurately assess the prognosis of phyllodes tumor (PT) of the breast. This article aimed to investigate the correlation between PT prognosis and clinicopathological features, treatment, and surgical margin. METHODS: The clinicopathological data of patients with pathologically confirmed PT at our institution were retrospectively collected. Univariate and multivariate Cox proportional risk models were employed to test the effects of different variables on the prognosis of PT...

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) is a landmark protein in determining the targeted treatment of breast cancer (BC). However, the latest research shows that different intensity of HER2 protein expression levels in BC leads to different clinical characteristics, treatment, and prognosis, especially in HER2 low expression patients. Therefore, this study intends to analyze and compare the clinicopathologic features and prognosis of BC patients with low and zero HER2 expression from The Cancer Genome Atlas (TCGA) database and the data collected by our center...

BACKGROUND: Breast cancer lymphedema (BCL) is one of the most common complications of breast cancer. Common western medical treatments for BCL, such as western medicine and lymphatic drainage, are ineffective, and recurrence may easily occur, making treatment more challenging and placing a heavier burden on patients. Acupuncture therapy is commonly used to treat BCL in China, and there are many acupuncture therapies, including acupuncture, moxibustion, and the combination of acupuncture and moxibustion...

BACKGROUND: Breast cancer is the most common cancer in women. The tumor is prone to metastasize in the brain, lung, liver, bone, and other organs; however, generally, it is less likely to metastasize in the digestive tract. Thus, breast cancer metastasizes to colon is rarely happened and easily ignored by clinicians. Such misdiagnosis may lead to delay the further diagnosis and treatment of patients, or even cause the life danger of patients due to the progress of the disease. Therefore, we propose such case reports to arouse clinicians' attention to the rare case of digestive tract metastasis after treatment of breast cancer...

BACKGROUND: Triple-negative breast cancer (TNBC) is a highly heterogeneous disease and the current prognostic system cannot meet the clinical need. Interactions between immune responsiveness and tumor cells plays a key role in the progression of TNBC and macrophages are vital component of immune cells. A prognostic model based on macrophages may have great accuracy and clinical utility. METHODS: For model development, we screened early stage (without metastasis) TNBC patients from The Cancer Genome Atlas (TCGA) database...

BACKGROUND: Trastuzumab (H) and pertuzumab (P) plus chemotherapy is the standard guideline-recommended neoadjuvant therapy recommended for patients with human epidermal growth factor receptor 2 (HER2)-positive locally advanced breast cancer (BC), which has dramatically improved patient prognosis. However, over 10% of patients develop primary drug resistance to HP and did not respond to treatment. There is no standard second-line neoadjuvant therapy approach for these individuals at the present...

BACKGROUND: Pancreatic fistula (PF) is the main complication in patients undergoing pancreaticoduodenectomy. Computed tomography (CT) value can reflect pancreatic tissue characteristics which is related to PF. This study was designed to study the relationship between the preoperative CT value and pancreatic fistula. METHODS: We retrospectively reviewed the clinical and medical data of patients undergoing pancreaticoduodenectomy from 2017 to 2021. The pancreatic CT value and the CT value ratios of the pancreas and abdominal aorta (PCT /ACT ) were measured and compared between the PF group and non-PF group...

BACKGROUND: The aim of this study was to investigate the expression of insulin receptor (IR) in the blood vessels of patients with breast cancer (BC) with or without type 2 diabetes mellitus (DM2) and its relationship with histopathological features of BC tissues and patient prognosis. METHODS: A total of 124 patients with BC diagnosed and treated at The Affiliated Hospital of Putian University between January 2018 and January 2019 were eligible for this study. According to the presence or absence of DM2, they were then divided into 2 groups: patients with BC and DM2 (DBC group, n=26) and patients with BC and without DM2 (BC group, n=98)...

BACKGROUND: The prognosis of multifocal multicentric breast cancer (MIBC) was related to many factors, and there are different recommendations for surgical approaches. We compare the effects of breast-conserving surgery (BCS) and mastectomy on the survival of multifocal multicenter breast cancer female patients. METHODS: A total of 38,164 female patients with pathologically confirmed multifocal multicenter invasive breast cancer from 2000 to 2018 in the Surveillance, Epidemiology, and End Results (SEER) database were extracted, and the effects of different factors on the survival of these patients were retrospectively analyzed...

BACKGROUND: Differentiating among the different types of parotid tumors on imaging is useful for guiding clinical disposition, which ultimately may lead to surgical management. The goal of this study was to determine whether quantitative T2 signal characteristics and morphologic features on magnetic resonance imaging (MRI) can serve as predictive biomarkers for distinguishing between tumor types. METHODS: A retrospective review of T2-weighted MRIs in patients with pathology-proven parotid tumors was performed...

BACKGROUND: Pancreaticojejunal anastomotic stenosis (PJS) after pancreaticoduodenectomy (PD) is difficult to treat. Single-balloon enteroscope-assisted endoscopic retrograde pancreatography (SBE-assisted ERP) is a safe way to treat PJS with the strength of minimally invasion and repeatability, but since its technical difficulty and few patient number, data on long-term outcomes remain limited. The optimal treatment is still unknown. We aim to study the safety, effectiveness, and long-term outcome of single balloon enteroscopy-assisted (SBE-assisted) therapeutic ERP in patients with PJS in this study...

BACKGROUND: Breast surgery is one of the most common surgeries in the world, and pain after breast surgery is very common, representing one of the key factors affecting the quality of life after surgery. With the development of clinical techniques, thoracic paravertebral block (TPVB) has gradually become the preferred regional anesthesia technique for postoperative breast analgesia. METHODS: Using Web of Science as the data source, medical articles about the application of TPVB in breast surgery published from 1900 to 2022 were retrieved and imported into CiteSpace and VOSviewer software...
