BACKGROUND Single-agent doxorubicin has been widely used to treat unresectable hepatocellular carcinoma (HCC), but the response rate is low (< 20%) and there is no convincing evidence for improved survival. Cisplatin, interferon, doxorubicin, and fluorouracil (PIAF) used in combination, by contrast, has shown promise in a phase II study. We compared(More)
This phase III randomized study compared concurrent cisplatin-radiotherapy (CRT) versus radiotherapy (RT) alone in patients with locoregionally advanced nasopharyngeal carcinoma. A total of 350 patients were randomly assigned to receive external RT alone or concurrently with cisplatin at a dosage of 40 mg/m(2) weekly. The primary endpoint was overall(More)
OBJECTIVES To study the effect of adding chemotherapy to radiotherapy (RT) on overall survival and event-free survival for patients with nasopharyngeal carcinoma. METHODS AND MATERIALS This meta-analysis used updated individual patient data from randomized trials comparing chemotherapy plus RT with RT alone in locally advanced nasopharyngeal carcinoma.(More)
PURPOSE A prospective randomized trial was conducted to compare chemoradiotherapy against radiotherapy alone in the treatment of locoregionally advanced nasopharyngeal carcinoma. METHODS AND MATERIALS Eighty-two patients with histologically proven nasopharyngeal carcinoma who had either Ho's N3 staging or any N stage with a nodal diameter of > or = 4 cm(More)
BACKGROUND Cancer patients who are hepatitis B virus (HBV) carriers and undergoing chemotherapy (CT) may be complicated by HBV reactivation. Over 80% of hepatocellular carcinoma (HCC) patients are HBV carriers; however, the incidence of HBV reactivation during CT has not been well-reported. A prospective study was conducted to determine the incidence of HBV(More)
BACKGROUND We aimed to improve the outcomes for locoregionally advanced nasopharyngeal carcinoma by testing the feasibility and safety of the addition of bevacizumab to chemoradiotherapy. METHODS We enrolled patients older than 18 years with stage IIB-IVB nasopharyngeal carcinoma from 19 centres in North America and Hong Kong. Treatment consisted of three(More)
PURPOSE Aberrant activation of the Wnt/beta-catenin signaling pathway is associated with multiple tumors including colorectal cancer (CRC). WNT5A is a member of the nontransforming Wnt protein family, whose role in tumorigenesis is still ambiguous. We investigated its epigenetic alteration in CRCs. EXPERIMENTAL DESIGN We examined its expression and(More)
PURPOSE To assess the efficacy of neoadjuvant paclitaxel and carboplatin (TC) followed by concurrent cisplatin and radiotherapy (RT) in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) and to monitor treatment response with plasma Epstein-Barr virus (EBV) DNA. PATIENTS AND METHODS Thirty-one patients with International Union Against(More)
PURPOSE For cancer patients receiving cytotoxic chemotherapy, hepatitis B virus (HBV) reactivation is a well described complication resulting in varying degrees of liver damage. The objectives of this study were to assess the efficacy of the antiviral agent lamivudine in reducing the incidence of HBV reactivation and diminishing morbidity and mortality of(More)
Using real-time quantitative PCR, cell-free EBV DNA was detectable in the plasma of 96% (55 of 57) of nasopharyngeal carcinoma (NPC) patients (median concentration, 21058 copies/ml) and 7% (3 of 43) of controls (median concentration, 0 copies/ml). Advanced-stage NPC patients had higher plasma EBV DNA levels than those with early-stage disease. At 1 month(More)
