Tumor necrosis factor (TNF)-alpha is one of the pro-inflammatory cytokines highly expressed in Helicobacter pylori that inhibits gastric acid secretion. In this study we determined the effect of silibinin on TNF-alpha-induced MMP-9 expression in gastric cancer cell lines. MMP-9 mRNA and protein expression was dose-dependently increased by TNF-alpha in(More)
PURPOSE The frequency of immediate breast reconstruction (IBR) is increasing, and the types of reconstruction used are diverse. Adjuvant chemotherapy is a life-saving intervention in selected high-risk breast cancer patients. The aim of our study was to determine how IBR and type of reconstruction affect the timing of the initiation of chemotherapy. (More)
Although ultrasonography (US)-guided fine-needle aspiration biopsy (FNAB) is the most reliable diagnostic modality for evaluating thyroid nodules, 10% to 40% of FNAB samples yield indeterminate findings. The BRAF V600E mutation, a highly specific molecular marker for papillary thyroid carcinoma (PTC), well known for its prognostic value, has dubious(More)
PURPOSE To present the author's experience with various treatment methods of granulomatous lobular mastitis (GLM) and to determine effective treatment methods of GLM. METHODS Fifty patients who were diagnosed with GLM were classified into five groups based on the initial treatment methods they underwent, which included observation (n = 8), antibiotics (n(More)
PURPOSE Invasive pleomorphic lobular carcinoma (IPLC) is a very rare and distinct morphological variant of invasive lobular carcinoma (ILC), characterized by nuclear atypia and pleomorphism contrasted with the cytologic uniformity of ILC. This study evaluated clinicopathologic characteristics and prognosis of IPLC compared with invasive ductal carcinoma(More)
PURPOSE Recently, several clinicians have reported the advantages of simplicity and cosmetic satisfaction of absorbable mesh insertion. However, there is insufficient evidence regarding its long-term outcomes. We have investigated the surgical complications and postoperative examination from the oncologic viewpoint. MATERIALS AND METHODS From February(More)
PURPOSE IBTR! 2.0 is a web-based nomogram that predicts the 10-year ipsilateral breast tumor recurrence (IBTR) rate after breast-conserving therapy. We validated this nomogram in Korean patients. METHODS The nomogram was tested for 520 Korean patients, who underwent breast-conserving surgery followed by radiation therapy. Predicted and observed 10-year(More)
PURPOSE The available research work on types of treatment and the efficacy of adjuvant chemotherapy in older Korean patients is insufficient. Henceforth, this report assessed treatment patterns and the relationship between chemotherapy and survival in elderly Korean breast cancer patients. METHODS We identified women over 55 years of age diagnosed with(More)
The neuropathological findings in a patient with antemortem diagnosis of olivopontocerebellar atrophy (OPCA) and reduced leucocytic glutamate dehydrogenase (GDH) activity included cerebellar cortical degeneration, most marked in the superior vermis, mild atrophy of the pons and the inferior olivary nucleus, marked reduction of anterior horn cells at all(More)
