이 논문의 목적은 다문화주의와 관련해 미디어/문화연구의 분야에서 이루어진 기존 논의들을 비판적으로 검토하고 앞으로의 연구 방향성을 모색해 보려는 데 있다. 이를 위해 우리는 다음과 같은 세 가지 주제를 중점적으로 다루고자 한다. 먼저 서구에서 1970년대 이후부터 본격적으로 일어난 다문화주의 논쟁을 개관하고 국내에서 다문화주의가 부상하게 된 과정을 비판적으로 검토한다. 이와 더불어 국내에서는 다문화주의와 관련해 어떠한 연구들이 진행되어 왔고 거기에는 또 어떠한 특징이 있는지 미디어/문화연구 분야의 작업들을 중심으로 살펴보고자 한다. 이러한 논의를 바탕으로 다문화주의와 관련해 미디어/문화연구 분야에서는 현재 어떠한 연구가 시급하게 요청되는지, 우리의 사회문화적 맥락 속에서 장기적으로는 어떠한 연구가 필요한지 그 방향성을 가늠해보고자 한다.

PURPOSE: This study aimed to identify the association between Ki-67 level and the prognosis of patients with breast cancer, regardless of the timing of Ki-67 testing (using preoperative biopsy vs. postoperative specimen). METHODS: A total of 4177 patients underwent surgery between January 2008 and December 2016. Immunohistochemical Ki-67 levels, using either preoperative (1673) or postoperative (2831) specimens, were divided into four groups using cutoff points of 10%, 15%, and 20%. RESULTS: Gro

BACKGROUND: As patients tend to be diagnosed with breast cancer at an early stage, the demand for better cosmetic outcomes has increased. Several studies revealed that robot-assisted nipple-sparing mastectomy (RNSM) shows favorable outcomes. The aim of the study was to reveal the feasibility of RNSM using the da Vinci single-port (SP) system with a minimal incision, hidden in the arm. METHODS: From 2018 to 2021, 81 cases (70 patients) were retrospectively reviewed. Clinicopathologic characterist

Purpose: Lymphovascular invasion (LVI) is a well-known poor prognostic factor for early breast cancer. However, the effect of LVI on breast cancer subtype and node status remains unknown. In this study, we aimed to evaluate the clinical significance of LVI on the recurrence and long-term survival of patients with early breast cancer by comparing groups according to the subtype and node status. Methods: We retrospectively reviewed the medical records of 4554 patients with breast cancer who underw

Diagnosis of hepatocellular carcinoma (HCC) with gadoxetic acid-enhanced liver magnetic resonance imaging (MRI) poses certain unique challenges beyond the scope of current guidelines. The regional heterogeneity of HCC in demographic characteristics, prevalence, surveillance, and socioeconomic status necessitates different treatment approaches, leading to variations in survival outcomes. Considering the medical practices in Korea, the Korean Society of Abdominal Radiology (KSAR) study group for l

Objective: To validate the diffusion-weighted MRI (DWI) for differentiation of benign from malignant portal vein thrombosis. Materials and Methods: The Institutional Review Board approved this retrospective study and waived informed consent. A total of 59 consecutive patients (52 men and 7 women, aged 40–85 years) with grossly defined portal vein thrombus (PVT) on hepatic MRI were retrospectively analyzed. Among them, liver cirrhosis was found in 45 patients, and hepatocellular carcinoma in 47 p

ΔVbd% was associated with pCR in breast cancer after NCT, with the decreased group showing a lower rate of pCR than the stable group. Automated measurement of ΔVbd% may help predict the NCT response and prognosis in breast cancer.

TPS618 Background: It is unclear whether the clinical benefit of cytotoxic adjuvant chemotherapy (CT) could be replaced by ovarian-function suppression (OFS) in premenopausal, estrogen receptor (ER)+HER2- breast cancer patients who have high clinical risk score and low genomic risk assessed by multigene assays. The TAILORx trial included a subgroup of premenopausal women with high clinical risk scores and midrange RS scores and found that CT, in addition to endocrine treatment (ET), offered clea

Hormone receptor (HR)-positive breast cancer has a heterogeneous pattern according to the level of receptor expression. Patients whose breast cancers express low levels of estrogen receptor (ER) or progesterone receptor (PgR) may be eligible for adjuvant endocrine therapy, but limited data are available to support this notion. We aimed to determine whether HR expression level is related to prognosis. Tumors from 6042 patients with breast cancer were retrospectively analyzed for combined HR level

The high GET risk results can be predicted using traditional clinicopathological factors: tumor size, progesterone receptor, histological grade, HER2, and Ki-67. These results will be useful for treatment decision-making among clinically high-risk patients with HR-positive/HER2-negative and node-positive disease, helping to identify patients to whom the GET assay may not apply.

Purpose: Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the most common breast cancer types. While they differ biologically and pathologically, their association with axillary lymph node (ALN) metastasis and survival remains unclear. This study compares the clinical features of ILC and IDC to evaluate ALN surgery considerations for ILC patients. Materials and Methods: We retrospectively analyzed 3543 patients who underwent upfront surgery for early breast cancer at Yons
