Signal transducers and activators of transcription (STAT) proteins comprise a family of transcription factors latent in the cytoplasm that participate in normal cellular events, such as differentiation, proliferation, cell survival, apoptosis, and angiogenesis following cytokine, growth factor, and hormone signaling. STATs are activated by tyrosine(More)
PURPOSE We performed this phase III study to compare the irinotecan, leucovorin (LV), and fluorouracil (FU) regimen (FOLFIRI) versus the oxaliplatin, LV, and FU regimen (FOLFOX4) in previously untreated patients with advanced colorectal cancer. PATIENTS AND METHODS A total of 360 chemotherapy-naive patients were randomly assigned to receive, every 2(More)
The increasing evidence that gammadelta T cells have potent antitumor activity suggests their value in immunotherapy, particularly in areas of unmet need such as metastatic carcinoma. To this end, we initiated a phase I clinical trial in metastatic hormone-refractory prostate cancer to examine the feasibility and consequences of using the gammadelta T-cell(More)
PURPOSE To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non-small-cell lung cancer treated with chemotherapy. PATIENTS AND METHODS Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the(More)
Pterostilbene and 3,5-hydroxypterostilbene are the natural 3,5-dimethoxy analogs of trans-resveratrol and piceatannol, two compounds which can induce apoptosis in tumor cells. In previous studies we demonstrated the importance of a 3,5-dimethoxy motif in conferring pro-apoptotic activity to stilbene based compounds so we now wanted to evaluate the ability(More)
An important molecular target for metastatic CRC treatment is the epidermal growth factor receptor (EGFR). Many potential biomarkers predictive of response to anti-EGFR monoclonal antibodies (cetuximab and panitumumab) have been retrospectively evaluated, including EGFR activation markers and EGFR ligands activation markers. With regard to the "negative(More)
Recent studies suggest that aspartic proteinase Cathepsin D may be implicated in the process of tumor invasion and metastasis. In fact several in vitro observations showed that this proteinase may facilitate the spread of neoplastic cells through different mechanisms related to its proteolytic activity, by acting at different levels of the metastatic(More)
PURPOSE The aims of the TP53 Colorectal Cancer (CRC) International Collaborative Study were to evaluate the possible associations between specific TP53 mutations and tumor site, and to evaluate the prognostic and predictive significance of these mutations in different site, stage, and treatment subgroups. PATIENTS AND METHODS A total of 3,583 CRC patients(More)
BACKGROUND Biliary tract cancers are uncommon tumors with a poor prognosis and most patients present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, with poor response rates and a median survival of less than 6 months. Oxaliplatin and gemcitabine have shown an interesting activity as single agents in this(More)
The goals of this study were to evaluate the efficacy and toxicity of the gemcitabine/docetaxel combination in metastatic breast cancer previously treated with anthracyclines. Fifty-three patients with metastatic breast cancer who had failed or relapsed after anthracycline-based chemotherapy entered the study and were evaluable. Patients received(More)
