Clinical outcome according to tumor HER2 status and EGFR expression in advanced gastric cancer patients from the EXPAND study.
2013
4021 Background: In the EXPAND study adding cetuximab to first-line capecitabine and cisplatin chemotherapy (CT) failed to improve clinical outcome in patients (pts) with advanced gastric or gastroesophageal junction cancer. This analysis assessed treatment outcome according to tumor HER2 status (a pre-defined subgroup) and EGFR expression in EXPAND study pts. Methods: Tumor HER2 status was determined primarily by immunohistochemistry (IHC), HER2 +ve tumors were IHC 3+ or IHC 2+ and fluorescence in situ hybridization (FISH) +ve. EGFR expression was assessed by IHC. A continuous scoring system (scale of 0–300) was used to determine the level of EGFR expression. Biomarker status was correlat…

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, …
VEGFR-3 and CXCR4 as predictive markers for treatment with fluorouracil, leucovorin plus either oxaliplatin or cisplatin in patients with advanced es…
2014
Abstract Background Combination of fluoropyrimidines and a platinum derivative are currently standards for systemic chemotherapy in advanced adenocarcinoma of the stomach and gastroesophageal junction (GEJ). Nevertheless, individual likelihood for response to these therapeutic regimes remains uncertain. Even more, no predictive markers are available to determine which patients may benefit more from oxaliplatin versus cisplatin or vice versa. The new invasion and stem cell markers VEGFR-3 and CXCR4 have been linked prognostically with more aggressive esophagogastric cancer types. Thus, we aimed to assess correlations of VEGFR-3 and CXCR4 expression levels with clinical outcome in a randomize…
PRODIGE 59-DURIGAST trial: A randomised phase II study evaluating FOLFIRI + Durvalumab ± Tremelimumab in second-line of patients with advanced gastri…
2021
International audience; Gastric or gastro-oesophageal junction (GEJ) adenocarcinomas present poor overall survival (OS). First-line chemotherapy regimen for patients with HER2-negative tumours is based on a doublet or triplet of fluoropyrimidine plus platinum salt ± taxane. Second-line chemotherapy (Docetaxel or Irinotecan) improves OS which nonetheless remains poor (around 5 months). The first results of immune checkpoint inhibitors (anti-PD-1) combined with chemotherapy in metastatic gastric and GEJ cancers were discordant in recent phase III trials. Data on dual-blockade (anti-PD-L1 or anti-PD-1 plus anti-CTLA-4) plus chemotherapy are lacking. DURIGAST is a randomised, multicenter, non-c…
Neue Chemotherapeutika in der Therapie des fortgeschrittenen Magenkarzinoms

Over the last years the therapeutic possibilities for advanced gastric cancer have significantly increased. Here we discuss the new chemotherapeutic options and the existing results in palliative therapy.
Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.
2016
Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…
ELF regimen in advanced gastrointestinal malignancies: An analysis of its clinical effectiveness and toxicity
2011
A multi-institutional phase 11 study of the combination of levofolinic acid 100 mg/m2, VP16 120 mg/m2 and 5-fluorouracil 500 mg/m2 for 3 consecutive days was carried out on a series of 73 evaluable patients with low performance status affected by locally advanced and/or metastatic gastrointestinal carcinomas. Site of primary tumor were: stomach 26, large bowel 20, pancreas 16, gall-bladder 5, and liver 6. Among patients with gastric carcinoma, 2 patients (8%) had a complete response with a mean duration of 6.8+ months, and 9 (35%) had a partial response with a mean duration of 5.8+ months, for an overall response rate of 43%. Overall response rate was largely unsatisfactory in colorectal ca…
