Preradiation chemotherapy of children and young adults with malignant brain tumors: Results of the german pilot trial HIT'88/'89
1998
Background Preradiation chemotherapy could be beneficial in malignant brain tumors, because the blood-brain tumor-barrier is disrupted after surgery, bone marrow recovery--essential for intense chemotherapy--is still intact, and CNS toxicity and ototoxicity of active drugs are lower before irradiation of a child's brain. Patients and methods A neoadjuvant phase 2 and a single arm pilot trial were initiated to investigate the efficacy and toxicity of an intense multidrug regimen before radiotherapy in 147 patients aged between 3 and 29; 9 years with medulloblastoma (94), malignant glioma (22), ependymoma (21), and stPNET (10). They were treated with one or two cycles consisting of procarbazi…
RAS mutations and cetuximab in locally advanced rectal cancer: Results of the EXPERT-C trial
2013
Background: RAS mutations predict resistance to anti-epidermal growthfactor receptor (EGFR) monoclonal antibodies in metastatic colorectal cancer. We analysed RAS mutations in 30 non-metastatic rectal cancer patients treated with or without cetuximab within the 31 EXPERT-C trial. Methods: Ninety of 149 patients with tumours available for analysis were KRAS/BRAF wild-type, and randomly assigned to capecitabine plus oxaliplatin (CAPOX) followed by chemoradiotherapy, surgery and adjuvant CAPOX or the same regimen plus cetuximab (CAPOX-C). Of these, four had a mutation of NRAS exon 3, and 84 were retrospectively analysed for additional KRAS (exon 4) and NRAS (exons 2/4) mutations by using bi-di…
Body Mass Index as a Risk Factor for Toxicities in Patients with Advanced Soft-Tissue Sarcoma Treated with Trabectedin
2017
<b><i>Objectives:</i></b> Low body mass index (BMI) and/or low lean body mass have been shown to be risk factors for chemotherapy-related toxicities in a number of different cancers. However, no data are available regarding the role of BMI as a risk factor for developing toxicities related to the novel anticancer agent, trabectedin, in patients with soft-tissue sarcoma (STS). We evaluated the role of BMI as a risk factor for trabectedin-related toxicity in patients with STS. <b><i>Methods:</i></b> Data from 51 patients with metastatic/advanced STS treated with trabectedin after progression on ≥1 anthracycline ± ifosfamide regimen were retrospe…
Effect of priming ith granulocyte-colony-stimulating factor on the outcome of chemotherapy for acute myeloid leukemia
2003
BACKGROUND: Sensitization of leukemic cells with hematopoietic growth factors may enhance the cytotoxicity of chemotherapy in acute myeloid leukemia (AML). METHODS: In a multicenter randomized trial, we assigned patients (age range, 18 to 60 years) with newly diagnosed AML to receive cytarabine plus idarubicin (cycle 1) and cytarabine plus amsacrin (cycle 2) with granulocyte colony-stimulating factor (G-CSF) (321 patients) or without G-CSF (319). G-CSF was given concurrently with chemotherapy only. Idarubicin and amsacrin were given at the end of a cycle to allow the cell-cycle-dependent cytotoxicity of cytarabine in the context of G-CSF to have a greater effect. The effect of G-CSF on dise…
Patterns of adjuvant chemotherapy for stage II and III colon cancer in France and Italy
2013
European guidelines recommend adjuvant chemotherapy for stage III colon cancer but not for stage II.To determine the extent to which adjuvant chemotherapy was used in Italy and France.A common retrospective database of 2186 colon cancers diagnosed between 2003 and 2005 was analysed according to age, stage and presenting features.38.9% of patients with stage II and 64.6% with stage III received chemotherapy in Italy, 21.7% and 65.1% in France. For stage II, the association between country and chemotherapy was only significant in patients diagnosed out of emergency (ORItaly/France: 3.05 [2.12-4.37], p0.001) whereas patients diagnosed in emergency were as likely to receive chemotherapy in both…
Final results from a randomized phase 3 study of FOLFIRI \pm$ panitumumab for second-line treatment of metastatic colorectal cancer
2013
Abstract: Background: The study 20050181 demonstrated significant improvements in progression-free survival (PFS), objective response, and a nonsignificant trend toward increased overall survival (OS) with panitumumab-FOLFIRI versus FOLFIRI alone for second-line wild-type (WT) KRAS metastatic colorectal cancer (mCRC). Updated long-term data from a prespecified descriptive analysis are reported. Patients and methods: Patients receiving one prior mCRC treatment were randomly assigned (1:1) to panitumumab (6.0 mg/kg)-FOLFIRI versus FOLFIRI every 2 weeks. Co-primary end points (PFS and OS) were prospectively analyzed by tumor KRAS status. Results: One thousand one hundred and eighty-six patient…
Avelumab versus standard second line treatment chemotherapy in metastatic colorectal cancer patients with microsatellite instability: The SAMCO-PRODI…
2021
Abstract Immune checkpoint inhibitors have failed in treating metastatic colorectal cancer (mCRC) patients except those with dMMR/MSI tumors. However, until very recently we had only non-comparative promising data in this population with anti-programmed cell death 1/ programmed cell death ligand 1 (PD1/PD-L1) antibodies alone or combined with anti- cytotoxic T-lymphocyte-associated protein 4 (CTLA4) antibodies. This comparative phase II trial (NCT 03186326), conducted in more than 100 centers in France, will include dMMR/MSI mCRC patients with progression after a first-line treatment with chemotherapy ± targeted therapies, to evaluate efficacy and safety of the anti-PDL1 Avelumab versus a s…
Efficacy and Safety of Cetuximab/Irinotecan in Chemotherapy-Refractory Metastatic Colorectal Adenocarcinomas: A Clinical Practice Setting, Multicente…
2006
This study was designed to evaluate the efficacy and safety of irinotecan/cetuximab administered as third- or fourth-line therapy in a retrospective series of patients with metastatic colorectal cancer refractory to oxaliplatin and irinotecan. Patients and Methods: Most patients (90%) had been previously treated with adjuvant 5-fluorouracil/leucovorin, and all had received oxaliplatin-based regimens before receiving irinotecan- based second-line treatment. Sixty patients with irinotecan-refractory colorectal cancer received a regimen comprising weekly irinotecan 120 mg/m 2 as a 1-hour intravenous infusion and cetuximab 400 mg/m 2 infused over 2 hours as the initial dose and 250 mg/m 2 infus…
Safety and feasibility of CHOP/rituximab induction treatment followed by high-dose chemo/radiotherapy and autologous PBSC-transplantation in patients…
2003
Patients with no prior chemotherapy and with advanced and progressive follicular lymphoma (FCL) or mantle cell lymphoma (MCL) were enrolled into a treatment protocol combining CHOP/rituximab-CHOP therapy with subsequent consolidation high-dose therapy (HDT) to evaluate the safety and feasibility of this treatment. Overall, 15 patients were enrolled and 13 patients completed the entire treatment protocol without major toxicities or increased infectious complications. One patient withdrew consent after achieving complete remission (CR) prior to HDT. One patient was taken off study with signs of disease progression after induction treatment. All patients showed stable engraftment after HDT. Re…
Prognosis of patients with primary central nervous system lymphoma after high-dose chemotherapy followed by autologous stem cell transplantation
2013
High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011. We estimated survi…
