Background: The neutrophil–lymphocyte ratio (NLR) has been reported to correlate with patient outcome in several cancers, including breast cancer. We evaluated whether the NLR can be a predictive factor for pathologic complete response (PCR) after neoadjuvant chemotherapy (NAC) in patients with triple-negative breast cancer (TNBC). Methods: We analyzed the correlation between response to NAC and various factors, including the NLR, in 87 patients with TNBC who underwent NAC. In addition, we analy

The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has excellent cosmetic effects and its popularity is increasing worldwide. We present our experience with TOETVA and its short-term outcomes. This study included 110 consecutive patients who underwent TOETVA at a single institution between July 2016 and June 2020. We analyzed clinicopathologic data, short-term postoperative outcomes, and learning curve using cumulative summation (CUSUM) analysis. Of the 110 patients who underwen

Introduction: Oncological and surgical safeties are pivotal issues of cancer operations. Robotic thyroidectomy adds cosmetic advantage to those safeties. We have performed bilateral axillo-breast approach robotic thyroidectomies (BABART) since 2009 and recently started transoral robotic thyroidectomy (TORT) in 2017. This study aimed to compare the surgical outcomes of a single surgeon's initial TORT and BABART. Materials and Methods: We retrospectively collected data of 103 patients who underwen

PURPOSE: Surgical excision is recommended for complete evaluation of cellular fibroepithelial lesions identified from core needle biopsy. The purpose of this study was to determine factors associated with phyllodes tumor among cellular fibroepithelial lesions from core biopsies and develop a scoring system to predict the risk of phyllodes tumor. METHODS: We retrospectively reviewed clinical data of 169 breast lesions that were diagnosed as cellular fibroepithelial lesions from core needle biopsy

While <i>BRCA1/2</i> mutation carriers had a higher risk of developing CBC compared to non-carriers at high-risk of HBOC, the risk of IBTR was similarly high across breast cancer patients irrespective of the <i>BRCA</i> mutation. Further preventive strategies to reduce CBC and IBTR for all patients at high-risk of HBOC should be investigated.

We could not find any difference in mental QOL, psychosocial status, sexual function, and menopausal symptoms between the RRSO and non-RRSO groups. RRSO uptake only affected worse physical QOL. These results will help physicians counsel BRCA mutation carriers about the effect of RRSO on QOL.

Introduction: BRCA mutation testing allows index patients and their families to be provided with appropriate cancer risk-reduction strategies. Because of the low prevalence of BRCA mutations in unselected breast cancer patients and the high cost of genetic testing, it is important to identify the subset of women who are likely to carry BRCA mutations. In the present study, we examined the association between BRCA1/2 germline mutations and the immunohistochemical features of breast cancer. Method

Background/Objectives: This nationwide retrospective study evaluated the effects of anticancer therapy on osteoporosis in 126,132 Korean breast cancer survivors from 2002 to 2020. Methods: The Cox proportional hazards model assessed the effects of treatment on osteoporosis. To circumvent the guarantee-time bias for osteoporosis development, a landmark analysis was employed. A stabilized inverse probability of treatment weighting was performed to control any confounding bias. The propensity score

BACKGROUND: We investigated the impact of postreperfusion syndrome (PRS) on hyperglycemia occurrence and connecting (C) peptide release, which acts as a surrogate marker for insulin resistance, during the intraoperative period after graft reperfusion in patients undergoing living donor liver transplantation (LDLT) using propensity score (PS)-matching analysis. PATIENTS AND METHODS: Medical records from 324 adult patients who underwent elective LDLT were retrospectively reviewed, and their data w

We aimed to compare the prognosis of patients with close resection margins after breast-conserving surgery (BCS) with that of patients with negative margins and identified predictors of residual disease. A total of 542 patients with breast cancer who underwent BCS between 2003 and 2019 were selected and divided into the close margin (114 patients) and negative margin (428 patients) groups. The median follow-up period was 72 (interquartile range, 42–113) months. Most patients received radiation t
