Second-line chemotherapy in advanced pancreatic carcinoma: a multicenter survey of the Gruppo Oncologico Italia Meridionale on the activity and safet…
2007
Background: In daily clinical practice second-line chemotherapy (SLCT) is frequently given to patients with advanced pancreatic cancer failing gemcitabine-based first-line chemotherapy without solid scientific support. Patients and methods: A retrospective survey was carried out including 42 patients. Patients received standard FOLFOX4 regimen biweekly until progression or unacceptable toxicity. Results: Six partial responses (14%) and 16 stabilizations (38%) were recorded for a tumor growth control rate of 57%. The median time to progression (TtP) was 4 months (range 1–7 months), and median overall survival (OS) was 6.7 months (range 2–9 months). A stabilization of performance status (PS) …
Gemcitabine and cisplatin for inoperable and/or metastatic biliary tree carcinomas: a multicenter phase II study of the Gruppo Oncologico dell'Italia…
2006
Background The aim of the study was to test the clinical efficacy and toxicity profile of gemcitabine (GEM) in combination with cisplatin (CDDP) in a series of patients affected by unresectable and/or metastatic biliary tree carcinoma (BTC) previously untreated with chemotherapy. Patients and methods Overall 38 consecutive patients who satisfied eligibility criteria (10 with gall-bladder carcinoma and 28 with bile duct carcinoma) were included in this phase II study. Median age was 61 years with median PS 1. Treatment included GEM 1000 mg/m2/week as 30 min i.v. on days 1 and 8, and CDDP 75–80 mg/m2 on day 1 with adequate hydration protocol and forced diuresis. Treatment was repeated every 3…
Phase 2 Trial of Docetaxel, Gemcitabine, and Oxaliplatin Combination Chemotherapy in Platinum- and Paclitaxel-Pretreated Epithelial Ovarian Cancer
2009
Background: This phase 2 trial was designed to evaluate the efficacy and toxicity of a combination of docetaxel, gemcitabine, and oxaliplatin for platinum- and paclitaxel-pretreated epithelial ovarian cancer. Patients and Methods: Heavily pretreated patients (N = 30; median age, 61 years) received docetaxel, 55 mg/m2; gemcitabine, 500 mg/m2 (day 1); and oxaliplatin, 70 mg/m2 (day 2) biweekly. Twelve patients had platinum-sensitive disease, and 18 patients had platinum-resistant disease. Results: Median follow-up was 18.6 months. No differences in patient characteristics were observed between patients with carboplatinum-sensitive and carboplatinum-resistant disease. In patients with carbopla…
Phase II trial of docetaxel and carboplatin in recurrent platinum-sensitive ovarian, peritoneal and tubal cancer
2007
Abstract Objective. Docetaxel and carboplatin are active in relapsed ovarian, peritoneal and tubal cancer. Recently, two prospective-randomized trials showed an advantage of carboplatin combination regimen with paclitaxel or gemcitabine over carboplatinum alone in platinum-sensitive cases. The question on the most effective combination with the best tolerable side effects still needs to be answered. Methods. Eligible patients had recurrent ovarian, peritoneal or tubal cancer (platinum-free interval >6 months), performance status 0–2 and normal bone marrow, renal and hepatic function. 25 patients (age 18–75 years) were enrolled into this phase II trial. Patients with debulking operation of r…
Treatment of orofacial pain in patients with stylomandibular ligament syndrome (Ernest Syndrome).
2013
Introduction: Ernest syndrome involves the stylomandibular ligament. It is characterised by pain in the preauricular area and mandibular angle, radiating to the neck, shoulder, and eye on the same side, and associated with pain during palpation of that ligament. The purpose of this study is to describe the clinical characteristics, treatment, and course of the disease in a series of patients with Ernest syndrome. Methods: Retrospective observational study covering the period from 1998 to 2008. We recorded patients’ age, sex, duration of the disorder, and pain characteristics. All patients were injected with 40 mg triamcinolone acetonide at the mandibular insertion of the stylomandibular lig…
Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
Abstract 2903: IMAB362, a novel first-in-class monoclonal antibody for treatment of pancreatic cancer
2014
Abstract Pancreatic ductal adenocarcinoma (PDAC), the most frequent subtype (>80%) of pancreatic cancer (PC) is characterized by a generally lethal progress within a short period of time after primary diagnosis. Despite high efforts, the treatment options are very limited and mainly of palliative nature. Therefore, we investigated whether IMAB362 might represent a potential treatment option in this patient population. IMAB362 is a highly potent and tumor-cell selective therapeutic antibody which is currently in clinical development in gastro-esophageal cancer (in phase II and IIb trials). IMAB362 is directed against the tight junction molecule CLDN18.2, a proliferation-promoting tran…
5-Fluorouracil Selectively Kills Tumor-Associated Myeloid-Derived Suppressor Cells Resulting in Enhanced T Cell–Dependent Antitumor Immunity
2010
AbstractMyeloid-derived suppressor cells (MDSC) accumulate in the spleen and tumor bed during tumor growth. They contribute to the immune tolerance of cancer notably by inhibiting the function of CD8(+) T cells. Thus, their elimination may hamper tumor growth by enhancing antitumor T-cell functions. We have previously reported that some anticancer agents relied on T cell–dependent anticancer responses to achieve maximal efficacy. However, the effect of anticancer agents on MDSC has remained largely unexplored. In this study, we observed that gemcitabine and 5-fluorouracil (5FU) were selectively cytotoxic on MDSC. In vivo, the treatment of tumor-bearing mice with 5FU led to a major decrease …
Resistance to Gemcitabine in a Lymphoma Cell Line Resistant to Fas-mediated Apoptosis
2004
BACKGROUND: The T-cell lymphoma cell line HuT78B1, selected for resistance to Fas-mediated apoptosis, resulted unexpectedly resistant to the apoptotic and cytotoxic effects of gemcitabine (dFdC). We investigated whether this resistance was due to the impairment of the Fas/Fas-ligand (FasL) system. MATERIALS AND METHODS: dFdC effects were studied in HuT78B1 and in the parental Fas-sensitive HuT78 cells exposed to inhibitors of the Fas/FasL system. RESULTS: FasL- and Fas-blocking antibodies did not interfere with dFdC-induced apoptosis in HuT78 cells, whereas inhibitors of caspase-8, -9, -1 or -3 had partial inhibitory effects. Notably, in HuT78B1 cells there was a markedly reduced dFdC accum…
Polyaspartylhydrazide Copolymer-Based Supramolecular Vesicular Aggregates as Delivery Devices for Anticancer Drugs
2008
In this paper we report on three different hydrophilic copolymers based on alpha,beta-polyaspartylhydrazide (PAHy) bearing butyric groups in the side chain (C 4) (PAHy-C 4) or a combination of butyric groups and positive charged residues ((carboxypropyl)trimethylammonium chloride, CPTACl) (PAHy-C 4-CPTA) that were synthesized and used for the preparation of new supramolecular vesicular aggregates (SVAs) containing gemcitabine as an antitumor drug. Gemcitabine-loaded SVAs containing synthesized PAHy derivatives were characterized from the physicochemical and technological point of view and the in vitro toxicity and anticancer activity on two different human cancer cell lines, i.e., CaCo-2 (h…
