Rheumatoid arthritis (RA) is characterized by progressive destruction of the affected joints. The pathophysiology results from genetic susceptibility and autoimmune phenomena, leading to tissue inflammation and synovial hyperplasia termed pannus, which irreversibly destroys cartilage and bone. The current treatment options, which suppress immune responses(More)
PURPOSE Neoadjuvant concomitant chemoradiotherapy has been used in cases of locally advanced rectal cancer to preserve sphincter function, decrease local recurrence, and improve survival. Preoperative staging is essential for planning and providing optimal therapy. The purpose of this study is to determine the accuracy of staging with magnetic resonance(More)
Overexpression of Her2/neu is implicated in the development of resistance to the antiestrogen tamoxifen (TAM) that exerts its inhibitory effect through interaction with estrogen receptor (ER). Whereas Her2/neu and ER are believed to be important cell survival/death factors in human breast cancer cells, if and how they interact to confer resistance to(More)
OBJECTIVE The purpose of this prospective study was to investigate the toxicity and efficacy of integrating extended-field para-aortic and pelvic external radiation, high-dose-rate intracavity brachytherapy, and concurrent and adjuvant cisplatin-based chemotherapy for locally advanced cervical cancer. METHOD A phase I/II study was performed from 1998 to(More)
Radiotherapy is an effective treatment for head and neck, skin, anogenital, and breast cancers. However, radiation-induced skin morbidity limits the therapeutic benefits. A low-toxicity approach to selectively reduce skin morbidity without compromising tumor killing by radiotherapy is needed. We found that the antitumor agents known as histone deacetylase(More)
Treatment of hepatocellular carcinoma (HCC) cells with butyrate can induce apoptosis irrespective of hepatitis B virus integration. No information is available, however, regarding the effect of butyrate on HCC in the presence of hepatitis C virus (HCV) because some HCV proteins can regulate cell survival. By gene transfer, we found that HCV core enhances(More)
In addition to genetic changes, epigenetic aberrations also play important roles in radiation- and chemical-induced disorders and carcinogenesis. The present study investigated whether epigenetic therapy with a histone deacetylase (HDAC) inhibitor has dual benefits for radiation-induced oral mucositis and chemical-induced oral carcinogenesis, which should(More)
PURPOSE This study established a prognostic scoring system for nasopharyngeal carcinoma (NPC), which estimates the probability of locoregional (LR) control following definitive conformal radiotherapy. METHODS AND MATERIALS Patients with nondisseminated NPC at initial presentation (n = 630) were enrolled in this study. All patients had magnetic resonance(More)
Hepatitis B virus (HBV) is implicated in liver cancer. The aim of this study was to find out whether HBV or its components [HBV surface antigen (HBsAg), HBV core protein (HBc), and HBV X protein (HBx)] could interfere with the host DNA damage response and repair pathway. The full HBV genome or individual HBV open-reading frame (ORF) was introduced into(More)
Neoadjuvant chemoradiation therapy has improved the local control rate and overall survival in locally advanced rectal cancers. The purpose of this retrospective study is to evaluate the correlation between the final pathologic stage and survival in these patients. Patients with biopsy-proven rectal carcinoma, pretreatment staging by magnetic resonance(More)
