Chemotherapy in advanced pancreatic cancer
1997
Patients with advanced adenocarcinomas of the pancreas have an exceptionally poor prognosis. Modest activity has been demonstrated with single agents (response rates of 25% at best with 5-fluorouracil [5-FU] and mitomycin). Better results have not been obtained by combination chemotherapy. Improvements in the palliation have been achieved by treatment with 5-FU, folinic acid (FA), and interferon-alpha-2A (IFN-alpha) weekly in the context of a phase II trial. Of 57 evaluable patients, eight (14%) had a partial response (PR), eight (14%) a minor response (MR), and 28 (49%) had no change of disease (NC). The median survival time was 10 mo for patients with progressive disease. Twenty-two out o…
Paclitaxel, carboplatin and gemcitabine combination as induction chemotherapy for stage IIIA N2 bulky non-small cell lung cancer
2005
<i>Background:</i> Induction chemotherapy followed by surgical resection or definitive radiotherapy for patients affected by stage IIIA N2 bulky non-small cell lung cancer (NSCLC) has been investigated in several trials. <i>Patients and Methods:</i> In this present study, 52 patients with stage IIIA N2 bulky NSCLC with cytologically or histologically confirmed mediastinal lymph node involvement received paclitaxel 175 mg/mq on day 1, carboplatin AUC 5 on day 1 and gemcitabine 1,000 mg/mq on day 1 and 8 every 3 weeks for three cycles as induction chemotherapy. <i>Results:</i> Objective response (4 complete remission and 36 partial remission) was achieved i…
Chemoimmunotherapy with O-FC in previously untreated patients with chronic lymphocytic leukemia
2011
We conducted an international phase 2 trial to evaluate 2 dose levels of ofatumumab, a human CD20 mAb, combined with fludarabine and cyclophosphamide (O-FC) as frontline therapy for chronic lymphocytic leukemia (CLL). Patients with active CLL were randomized to ofatumumab 500 mg (n = 31) or 1000 mg (n = 30) day 1, with fludarabine 25 mg/m2 and cyclophosphamide 250 mg/m2 days 2-4, course 1; days 1-3, courses 2-6; every 4 weeks for 6 courses. The first ofatumumab dose was 300 mg for both cohorts. The median age was 56 years; 13% of patients had a 17p deletion; 64% had β2-microglobulin > 3.5 mg/L. Based on the 1996 National Cancer Institute Working Group (NCI-WG) guidelines, the complete respo…
Docetaxel and oxaliplatin in the second-line treatment of platinum-sensitive recurrent ovarian cancer: a phase II study.
2007
ABSTRACT Background A prospective phase II study was conducted to evaluate the efficacy and toxicity of the combination docetaxel (Taxotere) (DTX) and oxaliplatin (OXA) in ovarian cancer patients recurring after a platinum-free interval (PFI) >12 months. Patients and methods DTX, 75 mg/m2, was administered by 60 min i.v. infusion, followed by OXA, 100 mg/m2, given by a 2 h i.v., on day 1 every 21 days. Results From October 2003 to June 2006, 43 ovarian cancer patients were enrolled. Median PFI was 26 months. All patients were available for response evaluation: 17 complete responses and 12 partial responses were registered, for an overall response rate of 67.4%. The median response duration …
Systemic Treatment in Advanced Phyllodes Tumor of the Breast: A Multi-institutional European Retrospective Case-series Analyses
2022
Abstract Background: We aimed at investigating outcome of systemic treatments in advanced breast PT. Methods: All cases of advanced breast PT treated with systemic treatments from 1999 to 2019, in one of the referral sarcoma centres involved in the study, were retrospectively reviewed. Results: 56 female patients were identified. Median age was 52 (range 25-76) years. Patients re-ceived a median number of 2 systemic treatments (range 1-4). Best responses according to RECIST were: 1 (3.7%) CR, 11 (40.7%) PR, 6 (22.2%) SD, 9 (33.3%) PD with anthracyclines plus ifosfamide (AI); 2 (16.7%) PR, 4 (33.3%) SD, 6 (50.0%) PD with anthracycline alone; 3 (18.8%) PR, 4 (25.0%) SD, 9 (56.3%) PD with high…
Oxaliplatin and Capecitabine-Based Chemoradiotherapy for Gastric Cancer—An Extended Phase I MARGIT and AIO Trial
2008
Purpose Adjuvant 5-fluorouracil–based chemoradiotherapy has been shown to improve the prognosis of gastric cancer. To optimize these results, in the present study oxaliplatin and capecitabine were used instead of 5-fluorouracil. We sought to determine the maximum tolerated dose and the dose-limiting toxicities (DLT) of these drugs in combination with intensity-modulated radiotherapy. Methods and Materials Patients with resected adenocarcinoma of the stomach or the gastroesophageal junction were included. They received two cycles of induction chemotherapy (oxaliplatin and capecitabine [XelOx] regimen). Using standard Phase I methodology, patients received 45 Gy in 1.8-Gy fractions either in …
Cyclic pentapeptide cRGDfK enhances the inhibitory effect of sunitinib on TGF-β1-induced epithelial-to-mesenchymal transition in human non-small cell…
2020
AbstractIn human lung cancer progression, the EMT process is characterized by the transformation of cancer cells into invasive forms that migrate to other organs. Targeting to EMT-related molecules is emerging as a novel therapeutic approach for the prevention of lung cancer cell migration and invasion. Traf2- and Nck-interacting kinase (TNIK) has recently been considered as an anti-proliferative target molecule to regulate the Wnt signaling pathway in several types of cancer cells. In the present study, we evaluated the inhibitory effect of a tyrosine kinase inhibitor sunitinib and the integrin-αVβ3targeted cyclic peptide (cRGDfK) on EMT in human lung cancer cells. Sunitinib strongly inhib…
Challenges and new prospects in hepatosplenic γδ T-cell lymphoma.
2014
Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of lymphoid neoplasms characterized by aggressive clinical behavior and dismal prognosis. Hepatosplenic γδ T-cell lymphoma (γδ-HSTL) is a particular form of PTCL that arises from a small subset of γ/δ T-cell receptor-expressing lymphocytes. γδ-HSTL has a rapidly progressive course and poor outcome due also to its refractoriness to conventional chemotherapy regimens. The very low incidence of γδ-HSTL, along with its propensity to mimic different pathological entities, makes this lymphoma a true diagnostic challenge. In this review, we highlight the biological and clinical features of γδ-HSTL that contribute to making this lymphoma…
FOLFIRI regimen in advanced colorectal cancer: the experience of the Gruppo Oncologico dell'Italia Meridionale (GOIM)
2005
Purpose: To verify the experience of the GOIM in the treatment of advanced colorectal cancer patients with the FOLFIRI combination therapy. Patients and methods: Patients entered in three consecutive trials of the GOIM (protocols no. 9706, 9901, and 2301) were reported in this analysis. A total of 287 chemotherapy-naive patients were treated with FOLFIRI regimen: Irinotecan 180mg/m 2 on day 1 with LV5FU2 regimen (LV at 100mg/m 2 administered as a 2-hour infusion before FU at 400mg/m 2 as an intravenous bolus injection, and FU at 600mg/m 2 as a 22-hour infusion immediately after 5FU bolus injection on day 1 and 2); the treatment was repeated every 2 weeks. Results: 287 patients entered in th…
Bortezomib: a new pro-apoptotic agent in cancer treatment.
2010
Bortezomib is a proteasome inhibitor. It targets the ubiquitin-proteasome pathway with subsequent inhibition of the degradation of proteins involved in cell cycle regulation and cancer cell survival. The best known molecular mechanism concerns the inhibition of IkappaB breakdown and the related stabilization of NFkappaB, thus preventing its translocation to the nucleus for the activation of downstream pathways. Bortezomib is the only drug in this class which has been approved for clinical use. It has shown an efficient antitumor effect in a phase III clinical trial (APEX) involving relapsed multiple myeloma patients. Response rate, time to progression and overall survival have been improved…
