hsa-mir-483-3p modulates delayed breast cancer recurrence.

Patients with estrogen receptor-positive breast cancer undergoing continuous adjuvant hormone therapy often experience delayed recurrence with tamoxifen use, potentially causing adverse effects. However, the lack of biomarkers hampers patient selection for extended endocrine therapy. This study aimed to elucidate the molecular mechanisms underlying delayed recurrence and identify biomarkers.

Minimal Access vs Conventional Nipple-Sparing Mastectomy.

Importance: While nipple-sparing mastectomy (NSM) for breast cancer was only performed using the open method in the past, its frequency using endoscopic and robotic surgical instruments has been increasing rapidly. However, there are limited studies regarding postoperative complications and the benefits and drawbacks of minimal access NSM (M-NSM) compared with conventional NSM (C-NSM).

Objective: To examine the differences in postoperative complications between C-NSM and M-NSM.

Prognosis and Adjusting Factors in Elderly Patients With Triple-Negative Breast Cancer: Comparing With Young and Middle Age Groups.

Purpose: Proper breast cancer screening and treatment should be considered in the elderly population; however, some tend to be less proactive. Our study aimed to investigate the impact of old age on treatment and prognosis in triple-negative breast cancer (TNBC).

Method: The study included patients with primary TNBC stage I-III diagnosed from 2002 to 2019 in single institution and retrospectively analyzed.

Obstetric and psychiatric history as predictors for psychosomatic symptoms among Korean perimenopausal women.

Objectives: Menopause presents various physical and psychological disturbances for women and comes at a high financial cost. Therefore, this study aimed to identify factors influencing menopause symptoms.

Study Design: Data of Korean perimenopausal women aged 40-60 (n = 1060; mean age, 46.

The effects of music therapy on the psychological status of women with perimenopause syndrome.

Objective: Women experience many physical and psychological changes with the reduction of progesterone and estrogen as ovarian function gradually weakens. This study applied a music psychotherapy program as a nonpharmacological treatment method in addition to treatment using drugs such as hormone therapy for perimenopausal women.

Method: This study's pre-post, control-experimental research compared 20 women in the music psychotherapy experimental group and 20 in the cognitive behavioral therapy (CBT) control group.

Diagnostic accuracy of a three-protein signature in women with suspicious breast lesions: a multicenter prospective trial.

Background: Mammography screening has been proven to detect breast cancer at an early stage and reduce mortality; however, it has low accuracy in young women or women with dense breasts. Blood-based diagnostic tools may overcome the limitations of mammography. This study assessed the diagnostic performance of a three-protein signature in patients with suspicious breast lesions.

Mutational Analysis of Triple-Negative Breast Cancer Using Targeted Kinome Sequencing.

Purpose: Triple-negative breast cancer (TNBC) does not have defined therapeutic targets and is currently treated with chemotherapy only. Kinase dysregulation triggers cancer cell proliferation and metastasis and is a crucial therapeutic target for cancer. In this study, targeted kinome sequencing of TNBC tumors was performed to assess the association between kinome gene alterations and disease outcomes in TNBC.

A Randomized Controlled Trial for Doing vs. Omitting Intraoperative Frozen Section Biopsy for Resection Margin Status in Selected Patients Undergoing Breast-Conserving Surgery (OFF-MAP Trial).

Purpose: Intraoperative frozen section biopsy is used to reduce the margin positive rate and re-excision rate and has been reported to have high diagnostic accuracy. A majority of breast surgeons in the Republic of Korea routinely perform frozen section biopsy to assess margins intraoperatively, despite its long turnaround time and high resource requirements. This study aims to determine whether omitting frozen section biopsy for intraoperative margin evaluation in selected patients is non-inferior to performing frozen section biopsy in terms of resection margin positivity rate.

The clinical impact of extrathyroidal extensions on prognoses in pediatric differentiated thyroid cancers.

Background: The prognostic impact of extrathyroidal extensions (ETE) on clinical outcomes has not been well studied in pediatric thyroid cancers. The aim of this study was to analyze the clinicopathological characteristics and clinical outcomes according to the extent of ETE in pediatric and adolescent thyroid cancers.

Methods: This study retrospectively reviewed 89 papillary thyroid carcinoma (PTC) patients less than 19 years of age who underwent total thyroidectomy with central neck dissections (CND) between 1997 and 2018.

Target Calorie Intake Achievements for Patients Treated in the Surgical Intensive Care Unit.

Adequate nutritional support in critically ill patients is important, however, sometimes it has been neglected in perioperative period of patients at surgical intensive care units (SICU). The aim of this study was to investigate whether approaching target calorie intake of surgical patients influences on their clinical outcomes. A total of 279 patients who admitted at SICU in perioperative period from August 2014 to July 2016 at our hospital were analyzed.

Considerations in Oncoplastic Surgery.

The development of oncoplastic surgery (OPS) is one of the greatest achievements for the treatment of breast cancer. OPS combines oncological resection with plastic surgery techniques in a single procedure to allow the excision of tumors without compromising cosmetic outcome. It allows better aesthetic-functional outcomes and consequently an improvement of the psychological aspects of patients with breast cancer.

Programmed cell death-ligand 1 expression in stromal immune cells is a marker of breast cancer outcome.

The programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) axis plays an important role in antitumor immune responses. However, there is considerable inconsistency regarding the prognostic value of PD-L1 expression status in breast cancer. We sought to evaluate the differential prognostic impacts of tumoral versus stromal immune cell PD-L1 expression in primary breast cancer.

Radiologic and Pathologic Findings of Atypical Ductal Hyperplasia in the Male Breast: Case Report and Literature Review.

In this case report, we present the radiologic and pathologic findings of atypical ductal hyperplasia (ADH) in the male breast. It is well known that a high-risk lesion such as ADH is a precursor of breast cancer in females. However, the clinical significance of these lesions in the male breast is still uncertain because male breasts mainly consist of ducts without lobule formation, unlike the female breast.

Effects of Steady Low-Intensity Exercise on High-Fat Diet Stimulated Breast Cancer Progression Via the Alteration of Macrophage Polarization.

Physical inactivity and high-fat diet, especially high saturated fat containing diet are established risk factors for breast cancer that are amenable to intervention. High-fat diet has been shown to induce tumor growth and metastasis by alteration of inflammation but steady exercise has anti-tumorigenic effects. However, the mechanisms underlying the effects of physical activity on high-fat diet stimulated breast cancer initiation and progression are currently unclear.

High Endothelial Venule with Concomitant High CD8+ Tumor-Infiltrating Lymphocytes Is Associated with a Favorable Prognosis in Resected Gastric Cancer.

CD8+ tumor-infiltrating lymphocytes (TILs) play a major role in antitumor immunity. High endothelial venules (HEVs) are related to diverse immune cells in solid tumors. We analyzed CD8+ and Foxp3+ TILs in combination with HEVs to determine their prognostic role in advanced gastric cancer (AGC).

Risk Factors for Tamoxifen-Induced Ovarian Hyperstimulation in Breast Cancer Patients.

Introduction: Adjuvant endocrine therapy is an integral component of care for hormone-dependent breast cancer. Tamoxifen is a potent inducer of ovarian function and consequent hyperestrogenism in premenopausal women. However, the incidence rate and risk factors associated this phenomenon remain unclear.

Less Pain and Reduced Risk of Early Postoperative Ileus After Clipless Versus Conventional Laparoscopic Appendectomy.

Laparoscopic appendectomy (LA) is perceived as a procedure requiring a short hospital stay; however, some patients require prolonged hospitalization because of postoperative ileus and pain; therefore, we introduced clipless LA, using only an ultrasonic energy device only for coagulation. A total of 1013 patients (clipless LA; n=290 and conventional LA; n=723) who underwent LA at our hospital between January 2015 and February 2018 were analyzed. The mean operative time was shorter (P<0.

Asprosin attenuates insulin signaling pathway through PKCδ-activated ER stress and inflammation in skeletal muscle.

It has been reported that asprosin is a novel adipokine which is augmented in mice and humans with type 2 diabetes (T2DM). Asprosin stimulates hepatic gluconeogenesis under fasting conditions. However, the roles of asprosin in inflammation, endoplasmic reticulum (ER) stress, and insulin resistance in skeletal muscle has not been studied.

Management of benign papilloma without atypia diagnosed at ultrasound-guided core needle biopsy: Scoring system for predicting malignancy.

This study was designed to evaluate factors predicting malignancy in patients diagnosed with benign papilloma without atypia at ultrasound-guided CNB and to develop a scoring system predicting malignancy based on clinical, radiological and pathological factors on further excisional biopsy.

Methods: The study enrolled patients diagnosed with benign papillomas (including benign and atypical papillary lesions) at CNB.

Can We Skip Intraoperative Evaluation of Sentinel Lymph Nodes? Nomogram Predicting Involvement of Three or More Axillary Lymph Nodes before Breast Cancer Surgery.

Purpose: The American College of Surgeons Oncology Group Z0011 trial reported that complete dissection of axillary lymph nodes (ALNs) may not be warranted in women with clinical T1-T2 tumors and one or two involved ALNs who were undergoing lumpectomy plus radiation followed by systemic therapy. The present study was conducted to identify preoperative imaging predictors of ≥ 3 ALNs.

Materials And Methods: The training set consisted of 1,917 patients with clinical T1-T2 and node negative invasive breast cancer.

Factors associated with late recurrence after completion of 5-year adjuvant tamoxifen in estrogen receptor positive breast cancer.

Background: Recent large trials have shown the survival benefits of 10-year use of tamoxifen by reducing late recurrence compared with 5-year therapy in estrogen receptor(ER)-positive breast cancer. We tried to identify clinical factors associated with the late recurrence.

Methods: We reviewed our database of ER-positive patients who had received operations between 1996 and 2006 in two institutions.

In Vivo Tumor Growth Rate Measured by US in Preoperative Period and Long Term Disease Outcome in Breast Cancer Patients.

Objective: The aim of our study was to evaluate the effect of tumor growth rate, calculated from tumor size measurements by US, on breast cancer patients' outcome.

Patients And Methods: Breast cancer patients who received at least two serial breast ultrasonographies (US) in our institution during preoperative period and were surgically treated between 2002 and 2010 were reviewed. Tumor growth rate was determined by specific growth rate (SGR) using the two time point tumor sizes by US.
