Autoimmunity predicts prolonged survival in colon cancer patients undergoing GOLFIG biochemotherapy
14542 Background: A multi-center phase II trial has been designed to evaluate toxicity, anti-tumour and immune-biological activity of the bio-chemotherapy GOLFIG regimen in advanced colorectal cancer (A-CRC). Methods: The trial involved 46 patients (34/46 2nd line or more). The biweekly GOLFIG regimen consisted of gemcitabine (1,000 mg/m2, day 1), oxaliplatin (85 mg/m2, day 2), levofolinic acid (100 mg /m2, day 1,2) and 5-FU (400 mg/m2 as a bolus, and 800 mg/m2 as 24 hour infusion, days 1,2) followed by sc GM-CSF (100 μg, days 3 to 8) and sc IL-2 (0.5 X 106 IUs twice a day, days 9 to 14). Results: GOLFIG regimen was well tolerated and resulted very active (ORR = 56.5%; disease control = 91…
p53-Mediated downregulation of H ferritin promoter transcriptional efficiency via NF-Y.
The tumor suppressor protein p53 triggers many of the cellular responses to DNA damage by regulating the transcription of a series of downstream target genes. p53 acts on the promoter of the target genes by interacting with the trimeric transcription factor NF-Y. H ferritin promoter activity is tightly dependent on a multiprotein complex called Bbf; on this complex NF-Y plays a major role. The aim of this work was to study the modulation of H ferritin expression levels by p53. CAT reporter assays indicate that: (i) p53 overexpression strongly downregulates the transcriptional efficiency driven by an H ferritin promoter construct containing only the NF-Y recognition sequence and that the phe…
A phase II study of pegylated liposomal doxorubicin oxaliplatin and cyclophosphamide as second-line treatment in relapsed ovarian carcinoma
We carried out a phase II nonrandomized study to examine the level of activity of oxaliplatin, pegylated liposomal doxorubicin, and cyclophosphamide in a patient population with relapsed ovarian cancer pretreated with platinum derivatives and paclitaxel. Patients received oxaliplatin (85 mg/m2), pegylated liposomal doxorubicin (30 mg/m2), and cyclophosphamide (750 mg/m2). A total of 49 patients (39 assessable for toxicity and response) were enrolled in this trial. Neutropenia grade 3 was observed in six patients (15%) and anemia grade 3 in one patient (0.2%). Fatigue grade 1–2 occurred in 26 patients (66%), nausea/vomiting grade 1 in 23 patients (58%), and alopecia grade 1–2 in 19 patients …
