CONTEXT The role of adjuvant therapy in resectable pancreatic cancer is still uncertain, and no recommended standard exists. OBJECTIVE To test the hypothesis that adjuvant chemotherapy with gemcitabine administered after complete resection of pancreatic cancer improves disease-free survival by 6 months or more. DESIGN, SETTING, AND PATIENTS Open,(More)
Acute induction of oncogenic Ras provokes cellular senescence involving the retinoblastoma (Rb) pathway, but the tumour suppressive potential of senescence in vivo remains elusive. Recently, Rb-mediated silencing of growth-promoting genes by heterochromatin formation associated with methylation of histone H3 lysine 9 (H3K9me) was identified as a critical(More)
Constitutively activated nuclear factor (NF)-kappaB is observed in a variety of neoplastic diseases and is a hallmark of the malignant Hodgkin and Reed-Sternberg cells (H/RS) in Hodgkin lymphoma. Given the distinctive role of constitutive NF-kappaB for H/RS cell viability, NF-kappaB-dependent target genes were searched for by using adenoviral expression of(More)
Breast cancers are either primarily resistant to chemotherapy (intrinsic resistance), or respond to chemotherapy but later recur with a multidrug-resistant phenotype because of overexpression of the multidrug transporter P-glycoprotein1. The MDR1 gene encoding P-glycoprotein may be transcriptionaily regulated by a Y-box transcription factor2. We now report(More)
BACKGROUND Faced with unsatisfactory results of treatment for advanced Hodgkin's disease, we investigated three combinations of chemotherapy. METHODS From 1993 to 1998, 1201 eligible patients 15 to 65 years of age who had newly diagnosed Hodgkin's disease in unfavorable stage IIB or IIIA or stage IIIB or IV were randomly assigned to receive eight cycles(More)
BACKGROUND Whether it is possible to reduce the intensity of treatment in early (stage I or II) Hodgkin's lymphoma with a favorable prognosis remains unclear. We therefore conducted a multicenter, randomized trial comparing four treatment groups consisting of a combination chemotherapy regimen of two different intensities followed by involved-field(More)
PURPOSE To determine the prognostic value of the central downstream apoptosis effector BAX in relation to its upstream regulator p53 in R0-resected hepatic metastases of colorectal cancer. PATIENTS AND METHODS Retrospective analysis of 41 patients who underwent potentially curative resection of liver metastases from colarectal cancer was performed. Tumor(More)
PURPOSE Combined-modality treatment consisting of four to six cycles of chemotherapy followed by involved-field radiotherapy (IFRT) is the standard of care for patients with early unfavorable Hodgkin's lymphoma (HL). It is unclear whether treatment results can be improved with more intensive chemotherapy and which radiation dose needs to be applied. (More)
BACKGROUND Gemcitabine usually given until progressive disease (PD) is the main first-line treatment option for patients with inoperable advanced pancreatic cancer (APC). Currently there is no accepted active regimen for second-line chemotherapy. Previous phase II studies suggest clinical relevant activity of oxaliplatin, folinic acid and 5-FU (OFF). We(More)
Constitutive nuclear nuclear factor (NF)-kappaB activity is observed in a variety of hematopoietic and solid tumors. Given the distinctive role of constitutive NF-kappaB for Hodgkin and Reed-Sternberg (HRS) cell viability, we performed molecular profiling in two Hodgkin's disease (HD) cell lines to identify NF-kappaB target genes. We recognized 45 genes(More)
