Natural History of Malignant Bone Disease in Gastric Cancer: Final Results of a Multicenter Bone Metastasis Survey

2013

BackgroundBone metastasis represents an increasing clinical problem in advanced gastric cancer (GC) as disease-related survival improves. In literature, few data on the natural history of bone disease in GC are available.Patients and methodsData on clinicopathology, skeletal outcomes, skeletal-related events (SREs), and bone-directed therapies for 208 deceased GC patients with evidence of bone metastasis were statistically analyzed.ResultsMedian time to bone metastasis was 8 months (CI 95%, 6.125-9.875 months) considering all included patients. Median number of SREs/patient was one. Less than half of the patients (31%) experienced at least one and only 4 and 2% experienced at least two and …

PARALLEL 303: Phase 2 randomized study of pamiparib vs placebo as maintenance therapy in patients (pts) with inoperable locally advanced or metastati…

2021

3109 Background: A subset of gastric cancers exhibits platinum sensitivity and genomic instability that is characteristic of homologous recombination deficiency (HRD). Cells with HRD are sensitive to poly (ADP-ribose) polymerase (PARP) inhibition. PARP inhibitor maintenance therapy following platinum-based chemotherapy has been a successful treatment strategy in pts with ovarian cancer. Pamiparib is an orally administered selective PARP protein 1 and 2 (PARP1/2) inhibitor that has shown potent DNA-PARP trapping activity and crosses the blood brain barrier in preclinical studies. In early phase clinical studies (NCT02361723; NCT03333915), pamiparib showed an acceptable safety profile and pr…

Assessing molecular subtypes of gastric cancer: microsatellite unstable and Epstein-Barr virus subtypes. Methods for detection and clinical and patho…

2018

Background The molecular classification of gastric cancer recognises two subtypes prone to immune checkpoint blockade: the microsatellite unstable and the Epstein-Barr virus (EBV)-related tumours. We aim to assess the concordance between immunohistochemistry and PCR for microsatellite status evaluation, and explore the value of microsatellite instability (MSI) and EBV as predictive survival factors. Material and methods We collected 246 consecutively diagnosed gastric cancer cases in all stages and evaluated the microsatellite status using immunohistochemistry for mismatched repair (MMR) proteins and PCR. EBV expression was studied through in situ hybridisation. Results Forty-five (18%) cas…

A prospective trial for defining a subset of patients with limited metastatic gastric cancer who may be candidates for bimodal treatment strategies: …

2012

4090 Background: The utility of surgery for metastatic gastric cancer is debated. A prospective trial was performed to evaluate a prognostic model for selecting patients (pts) treated with systemic chemotherapy (ct) who may also be candidates for surgical intervention. Methods: Using a predefined algorithm pts with untreated gastric cancer were prospectively stratified into 3 groups: operable (OD), limited metastatic (LD), or extensive metastatic (ED) disease and treated with 5-FU, oxaliplatin, leucovorin and docetaxel (FLOT). LD was defined as: distant intra-abdominal lymph node metastases only or/and a maximum of 1 organ involved, normal serum alkaline phosphatase, < 5 liver lesions, …

A systematic review and meta-analysis of randomized trials on the role of targeted therapy in the management of advanced gastric cancer: Evidence doe…

2015

It is still uncertain if targeted therapy-based regimens in advanced gastric cancer actually produce survival benefit. To shed light on this important question, we performed a systematic review and meta-analyses on each relevant targeted-pathway. By searching literature databases and proceedings of major cancer meetings in the time-frame 2005–2014, 22 randomized clinical trials exploring targeted therapy for a total of 7022 advanced gastric cancer patients were selected and included in the final analysis. Benefit was demonstrated for antiangiogenic agents in terms of overall survival (HR 0.759; 95%CI 0.655–0.880; p < 0.001). Conversely no benefit was found for EGFR pathway (HR 1.077; 95%…

Progression-free survival (PFS) as a surrogate endpoint for overall survival (OS) in advanced/recurrent gastric cancer (AGC) treatment: Individual-pa…

2020

e16506 Background: In 2013, the GASTRIC (Global Advanced/Adjuvant Stomach Tumor Research through International Collaboration) evaluated the surrogacy of PFS based on IPD of 4,069 patients from 20 randomized trials of AGC. Treatment effects on PFS and on OS were only moderately correlated, and we could not validate PFS as a surrogate endpoint for OS. More recent trials, with refined inclusion criteria and higher standards for evaluating progression, may allow for a more accurate estimate of the correlation. The 2nd round of the GASTRIC sought to re-evaluate the surrogacy of PFS for OS in AGC. Methods: The GASTRIC database was updated with trials published after 2010 which used RECIST (Respo…

FOLFIRI plus sunitinib versus FOLFIRI alone in advanced chemorefractory esophagogastric cancer patients: A randomized placebo-controlled multicentric…

2013

4086 Background: Sunitinib is an receptor tyrosine kinase (RTK) inhibitor of VEGFR1-3, PDGFR-α-β, and other RTK. After we established Sunitinib (Sun) alone associated with limited response rate (RR) and good tolerability in refractory advanced esophagogastric cancer patients (Moehler et al. EUR J Cancer. 2011, 47: 1511), this double-blinded placebo-controlled phase II evaluated safety and efficacy of SUN as add-on in second-line or third-line FOLFIRI (ClinicalTrials.gov NCT01020630). Methods: Patients with failure of any prior docetaxel and/or platinum-based chemotherapy were randomized to receive 6-week cycles including FOLFIRI two weekly and SUN (25 mg) versus (vs) placebo (PLA) daily fo…

PaFLO: Pazopanib with 5-fluorouracil, leucovorin, and oxaliplatin (FLO) as first-line treatment in advanced gastric cancer: A randomized phase II stu…

2012

TPS4138 Background: VEGF inhibition in gastric cancer shows promising improvement of remission rate and progression-free survival (Ohtsu et al., JCO 2011). Pazopanib is an orally available tyrosine kinase inhibitor (TKI) selectively inhibiting VEGFR-1, -2, -3, c-kit and PDGFR. It is approved for treating renal cell cancer. A phase-I trial showed good tolerability of pazopanib with full-dose FOLFOX in solid tumors (Brady et al., ASCO, 2009). FLO is a widely used combination for advanced gastric cancer recommended in national guidelines. Methods: 75 Patients with HER-2-negative locally advanced or metastatic adenocarcinoma of the stomach or the gastro-esophageal junction will be randomized i…

Lapatinib in combination with ECF/x in EGFR1 positive first-line metastatic gastric cancer (GC): A phase II randomized placebo controlled trial (EORT…

2012

TPS4140 Background: Survival of HER2+ metastatic GC is prolonged by trastuzumab when administered with CF/X (VanCutsem, ASCO 2009). Lapatinib inhibits both EGFR1 and HER2, is active in HER2+ GC lines, and has shown clinical activity in uncontrolled phase II GC trials. A phase III trial of lapatinib with X + oxaliplatin in HER2+ (FISH) GC is closed to recruitment. Additional unaddressed questions include the efficacy and safety of lapatinib with ECF/X (epirubicin + cisplatin + 5-FU or capecitabine (X), which is a preferred chemotherapy (CT) regimen in GC), and its activity in patients (pts) with discordant FISH or IHC HER2 status or EGFR1+. Methods: This is a phase II, randomized, double- b…
