Gemcitabine (GEM) plus oxaliplatin, folinic acid, and 5-fluorouracil (FOLFOX-4) in patients with advanced gastric cancer
2005
Abstract BACKGROUND AND AIMS: oxaliplatin in combination with folinic acid (FA) and infusional 5-fluorouracil (5-FU) has shown significant anti-tumor activity in gastric cancer patients (FOLFOX). Previous studies have shown that gemcitabine (GEM), a new fluorinated anti-metabolite, enhances the individual anti-tumor activity of either 5-FU or oxaliplatin. We have therefore designed a multi-center phase II trial in order to test a novel GEM+FOLFOX-4 regimen in patients with metastatic gastric cancer. METHODS: we enrolled 36 patients, 28 males and 8 females, with an average age of 64.4 years (range 37-78), who received bi-weekly treatment with GEM (1,000 mg/m2 on day 1), levo-FA (100 mg/m2 on…
Randomized Multicenter Phase II Trial of Two Different Schedules of Irinotecan Combined with Capecitabine as First-Line Treatment in Metastatic Color…
2004
BACKGROUND The aim of the current randomized Phase II study was to investigate the efficacy and safety of capecitabine combined with irinotecan as first-line treatment in metastatic colorectal carcinoma (CRC). METHODS A total of 140 patients received capecitabine at a dose of 1250 mg/m2 twice daily on Days 2–15 and irinotecan at a dose of either 300 mg/m2 on Day 1 (Arm A) or 150 mg/m2 on Days 1 and 8 (Arm B) every 3 weeks. During the course of the study, enrollment was continued using lower doses of capecitabine (1000 mg/m2 twice daily) and irinotecan (Arm A: 240 mg/m2; Arm B: 120 mg/m2) to improve the safety profile of the combinations. RESULTS Efficacy was evaluable in 134 patients (68 in…
Cisplatin and gemcitabine with either vinorelbine or paclitaxel in the treatment of carcinomas of unknown primary site : results of an Italian multic…
2006
BACKGROUND. To date, the standard treatment for patients who have carcinoma of unknown primary site has not been established. METHODS. In this randomized Phase II study, 66 previously untreated patients (33 patients per arm) with carcinomas of unknown primary site received cisplatin (35 mg/m2) and gemcitabine (1000 mg/m2) with either paclitaxel (70 mg/m2) or vinorelbine (25 mg/m2), and all drugs were administered intravenously on Days 1 and 8 of a 21-day cycle. Twenty-nine patients (44%) presented with ≥2 involved sites. The pathologic diagnosis was mainly adenocarcinoma (48 patients; 72.7%) and squamous carcinoma (7 patients; 10.6%). RESULTS. In the first arm, 16 patients (48.5%) experienc…
Gemcitabine plus metronomic 5-fluorouracil or capecitabine as a second-/third-line chemotherapy in advanced adrenocortical carcinoma: a multicenter p…
2010
Adrenocortical carcinoma (ACC) is a rare neoplasm characterized by poor prognosis. First-line systemic treatments in advanced disease include mitotane, either alone or in combination with chemotherapy. Studies evaluating second-line therapy options have obtained disappointing results. This trial assessed the activity and toxicity of gemcitabine plus metronomic fluoropyrimidines in heavily pretreated advanced ACC patients. From 1998 to 2008, 28 patients with advanced ACC progressing after mitotane plus one or two systemic chemotherapy lines were enrolled. They received a combination of i.v. gemcitabine (800 mg/m2, on days 1 and 8, every 21 days) and i.v. 5-fluorouracil protracted infusion (2…
Ribonucleotide Reductase Messenger RNA Expression and Survival in Gemcitabine/Cisplatin-Treated Advanced Non-Small Cell Lung Cancer Patients
2004
Abstract Purpose: No chemotherapy regimen, including the widely used combination of gemcitabine/cisplatin, confers significantly improved survival over any other in metastatic non-small cell lung cancer (NSCLC); however, the selection of patients according to key genetic characteristics can help to tailor chemotherapy. Ribonucleotide reductase subunit M1 (RRM1) is involved in DNA synthesis and repair and in gemcitabine metabolism, and the excision repair cross-complementing group 1 (ERCC1) gene has been related to cisplatin activity. Experimental Design: Patients were part of a large randomized trial carried out from September 1998 to July 2000, comparing gemcitabine/cisplatin versus gemcit…
Treatment of Metachronous and Simultaneous Liver Metastases of Pancreatic Cancer
2009
<i>Aim:</i> Patients were analyzed who underwent treatment of liver metastases from pancreatic cancer. <i>Methods:</i> Selection criteria were the possibility of R0 resection of the primary and/or the liver metastases, no other sites of metastases, and the presentation of liver metastases. A comparison of treatment by surgery versus chemotherapy regarding overall survival and disease-free interval was performed. <i>Results:</i> Between 1996 and 2008, a total number of 23 patients were retrospectively identified from a prospective database of 193 cases of pancreatic cancer. In 14 cases, liver metastases were found simultaneously, and in 9 cases metachronou…
Phase II Study of Bevacizumab in Combination with Trastuzumab and Capecitabine as First-Line Treatment for HER-2-positive Locally Recurrent or Metast…
2012
Abstract We report the first results from a phase II, open-label study designed to evaluate the efficacy and safety of bevacizumab in combination with trastuzumab and capecitabine as first-line therapy for human epidermal growth factor receptor (HER)-2-positive locally recurrent (LR) or metastatic breast cancer (MBC). Patients were aged ≥18 years with confirmed breast adenocarcinoma, measurable LR/MBC and documented HER-2-positive disease. Patients received bevacizumab (15 mg/kg on day 1) plus trastuzumab (8 mg/kg on day 1 of cycle 1, 6 mg/kg on day 1 of each subsequent cycle) plus capecitabine (1,000 mg/m2 twice daily, days 1–14) every 3 weeks until disease progression, unacceptable toxici…
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…
Multicentre phase II trial of trastuzumab and capecitabine in patients with HER2 overexpressing metastatic pancreatic cancer
2012
Background: New therapeutic options for metastatic pancreatic cancer are urgently needed. In pancreatic cancer, overexpression of the epidermal growth factor receptor 2 (HER2) has been reported in up to 45%. This multicentre phase II study investigated the efficacy and toxicity of the HER2 antibody trastuzumab combined with capecitabine in the patients with pancreatic cancer and HER2 overexpression. Methods: Primary endpoint was progression-free survival (PFS) after 12 weeks. A total of 212 patients were screened for HER2 expression. Results: Immunohistochemical (IHC) HER2 expression was: 83 (40%) grade 0, 71 (34%) grade 1, 31 (15%) grade 2, 22 (11%) grade 3. A total of 17 patients with IHC…
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…
