Oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer: a multicenter phase II trial of the Southern Italy Cooperative Onc…
2009
Purpose: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer. Methods: Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m 2 iv and irinotecan 150 mg/m2 iv on day 1, 6S-folinic acid 250 mg/m2 iv and fluorouracil 750 mg/m2 iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles. Results: Sixty-three patients were treated, with a median of eight (range 1-12) cycles/patient. Two complete and 19 partial responses were registered (RR 33% [95% CI, …
Treatment of advanced adenocarcinomas of the exocrine pancreas and the gallbladder with 5-fluorouracil, high dose levofolinic acid and oral hydroxyur…
1996
BACKGROUND To date there is no established chemotherapeutic treatment for patients with unresectable locally advanced and/or metastatic carcinomas of the exocrine pancreas or the gallbladder. A multicenter Phase II trial has been performed by the Southern Italy Oncology Group with the aim of evaluating the clinical effectiveness and tolerability of weekly 5-fluorouracil (5-FU) in modulation with intravenous (i.v.) high dose levofolinic acid and oral hydroxyurea. METHODS A total of 70 patients fulfilling the standard eligibility for a Phase II study were enrolled in the trial. Forty patients had advanced pancreatic adenocarcinoma and 30 had advanced gallbladder carcinoma. The treatment sched…
PML as a potential predictive factor of oxaliplatin/fluoropyrimidine-based first line chemotherapy efficacy in colorectal cancer patients
2012
PML regulates a wide range of pathways involved in tumorigenesis, such as apoptosis, which is also one of the main mechanisms through which oxaliplatin and fluoropyrimidine exert their antineoplastic activity. The present study aims to investigate PML expression as a predictive factor of oxaliplatin/fluoropyrimidine therapy efficacy. Seventy-four metastatic colorectal cancer patients who received oxaliplatin/floropyrimidine-based first line therapy have been included in this retrospective study. PML expression was assessed by immunohistochemistry. PML down-regulation was detected in 39 (52.7%) patients (14 complete and 25 partial PML loss). RR was significantly lower (25.6%) in patients wit…
Molecular predictors of response to decitabine in advanced chronic myelomonocytic leukemia: a phase 2 trial.
2011
Abstract Hydroxyurea is the standard therapy of chronic myelomonocytic leukemia (CMML) presenting with advanced myeloproliferative and/or myelodysplastic features. Response to hypomethylating agents has been reported in heterogeneous series of CMML. We conducted a phase 2 trial of decitabine (DAC) in 39 patients with advanced CMML defined according to a previous trial. Median number of DAC cycles was 10 (range, 1-24). Overall response rate was 38% with 4 complete responses (10%), 8 marrow responses (21%), and 3 stable diseases with hematologic improvement (8%). Eighteen patients (46%) demonstrated stable disease without hematologic improvement, and 6 (15%) progressed to acute leukemia. With…
Update on capecitabine alone and in combination regimens in colorectal cancer patients
2010
Capecitabine is an orally administered fluoropyrimidine carbamate which has been developed as a prodrug of 5-FU with the goal to improve its tolerability and intratumoral drug concentration. The review aims to provide an evidence-based update of clinical trials investigating the clinical efficacy, adverse-event profile, dosage and administration of this drug, alone or in combination with conventional chemotherapeutics and/or new target-oriented drugs, in the management of colorectal cancer patients. © 2010 Elsevier Ltd.
Pemetrexed with or without matuzumab as second-line treatment for patients with stage IIIB/IV non-small cell lung cancer.
2010
Introduction This randomized phase II study investigated pemetrexed in combination with the epidermal growth factor receptor (EGFR)-targeting monoclonal antibody matuzumab compared with pemetrexed alone as second-line therapy for patients with advanced non-small cell lung cancer. Methods Patients received pemetrexed 500 mg/m 2 every 3 weeks either alone ( n = 50) or in combination with matuzumab at either 800 mg weekly ( n = 51) or 1600 mg every 3 weeks ( n = 47). The primary end point was objective response, as assessed by an independent review committee. Results Tumor EGFR expression was detected in 87% of randomized patients. The objective response rate for the pooled matuzumab-treated a…
Human equilibrative nucleoside transporter 1 (hENT1) levels predict response to gemcitabine in patients with biliary tract cancer (BTC)
2009
Background and aim: Translational data suggest that nucleoside transporters, in particular human equilibrative nucleoside transporter 1 (hENT1), play an important role in predicting clinical outcome after gemcitabine chemotherapy for several types of cancer. The aim of this study was to retrospectively determine patients' outcome according to the expression of hENT1 in tumoral cells of patients receiving gemcitabine-based therapy. Materials and Methods: The immunohistochemistry analysis was performed on samples from thirty-one patients with unresectable biliary tract cancer (BTC) consecutively treated with first line gemcitabine-based regimens. Results: Positive hENT1 staining patients were…
Interstitial lung disease associated with drug therapy
2004
Drug-associated interstitial lung disease (ILD) is not uncommon, with diverse patterns ranging from benign infiltrates to the potentially fatal acute respiratory distress syndrome. As acute respiratory failure due to drug-associated ILD has an unpredictable onset and rapid time course, establishing a diagnosis is often difficult. An accurate diagnosis is based on clinical, radiological (including high-resolution computed tomography) and histological manifestations, although is often only possible by exclusion. Cancer chemotherapy is commonly associated with acute disease that, on pathology, is often diffuse alveolar damage. Furthermore, a combination of drugs with or without radiotherapy ca…
GABA-A Receptors Regulate Neocortical Neuronal Migration In Vitro and In Vivo
2006
The cortical migration process depends on a number of trophic factors and on the activation of different voltage- and ligand-gated channels. We investigated the role of gamma-aminobutyric acid (GABA) type A receptors in the neuronal migration process of the newborn rat parietal cortex in vivo and in vitro. Local in vivo application of the GABA-A antagonist bicuculline methiodide (BMI) or the agonist muscimol via cortical surface Elvax implants induced prominent alterations in the cortical architecture when compared with untreated or sham-operated controls. BMI- and muscimol-treated animals revealed heterotopic cell clusters in the upper layers and a complete loss of the cortical lamination …
