Overall survival at 5 years of follow-up in a phase III trial comparing ipilimumab 10 mg/kg with 3 mg/kg in patients with advanced melanoma

2020

BackgroundWe have previously reported significantly longer overall survival (OS) with ipilimumab 10 mg/kg versus ipilimumab 3 mg/kg in patients with advanced melanoma, with higher incidences of adverse events (AEs) at 10 mg/kg. This follow-up analysis reports a 5-year update of OS and safety.MethodsThis randomized, multicenter, double-blind, phase III trial included patients with untreated or previously treated unresectable stage III or IV melanoma. Patients were randomly assigned (1:1) to ipilimumab 10 mg/kg or 3 mg/kg every 3 weeks for 4 doses. The primary end point was OS.ResultsAt a minimum follow-up of 61 months, median OS was 15.7 months (95% CI 11.6 to 17.8) at 10 mg/kg and 11.5 mont…

Phase II study of mitomycin C, etoposide and vindesine in metastatic stage IV non-small-cell lung cancer.

1991

A total of 72 patients with metastatic stage IV non-small-cell lung cancer (NSCLC) were treated with combination chemotherapy comprising the MEV regimen (mitomycin C, 8 mg/m2 given i. v. on day 1; etoposide, 100 mg/m2 given i.v. on days 1–3; and vindesine, 3 mg/m2 given i.v. on day 1; treatment repeated every 3 weeks). In 64 evaluable patients, the objective response rate was 37% (complete responses, 4.7%; partial responses, 32.3%). The median survival was 7.6 months for all patients. The treatment was very well tolerated. MEV proved to be an active and non-toxic regimen for the treatment of metastatic NSCLC.

Elevated tumor lactate concentrations predict for an increased risk of metastases in head-and-neck cancer.

2001

Purpose: Hypoxia shifts the balance of cellular energy production toward glycolysis with lactate generation as a by-product. Quantitative bioluminescence imaging allows for the quantitation of lactate concentrations in individual tumors. We assessed the relationship between pretreatment tumor lactate concentrations and subsequent development of metastatic disease in patients with newly diagnosed head-and-neck cancer. Methods and Materials: At the time of biopsy of the primary site, a separate specimen was taken and flash-frozen for subsequent quantitation of lactate concentration using a luciferase bioluminescence technique. The twodimensional spatial distribution of the bioluminescence int…

Bcl-2 and glutathione depletion sensitizes B16 melanoma to combination therapy and eliminates metastatic disease.

2007

Abstract Purpose: Advanced melanoma resists all current therapies, and metastases in the liver are particularly problematic. Prevalent resistance factors include elevated glutathione (GSH) and increased expression of bcl-2 in melanoma cells. GSH has pleiotropic effects promoting cell growth and broad resistance to therapy, whereas Bcl-2 inhibits the activation of apoptosis and contributes to elevation of GSH. This study determined the in vivo efficacy of combination therapies administered while GSH and Bcl-2 were individually and simultaneously decreased in metastatic melanoma lesions. Experimental Design: Highly metastatic murine B16 melanoma (B16M-F10) cells have elevated levels of both G…

Brain metastases following interleukin-2 plus interferon-alpha-2a therapy

2003

Abstract This study analyses the frequency and therapy of brain metastases in 94 stage IV melanoma patients after treatment with high-dose interleukin-2 (IL-2) and interferon-α (IFN-α) within three subsequent trials between 1990 and 1995. Central nervous system (CNS) metastases occurred in 28 patients (30%) during the potential follow-up period of 6 years. Time to occurence of brain metastases varied between 1 and 53 months, with a median of 10 months. Of 28 patients, 19 had

Abstract CT-08: A Phase 1 study of MEHD7945A (MEHD), a first-in-class EGFR/HER3 dual action antibody, in patients (pts) with locally advanced or meta…

2012

Abstract Background Dysregulated human epidermal growth factor receptor tyrosine kinase (HER RTK) signaling is an important driver of tumor growth, metastasis, and survival. Extensive HER RTK co-expression and heterodimerization suggest that simultaneous blockade of multiple RTKs may be more effective than targeting individual RTKs, and may help prevent or delay development of resistance mechanisms. MEHD is a novel dual-action human IgG1 antibody. Each antigen-binding fragment blocks ligand binding to both EGFR and HER3, which is meant to inhibit the activity of the major ligand-dependent HER dimers in cancer. MEHD also elicits antibody-dependent cell-mediated cytotoxicity, and has single-a…

Pancreatic cancer: Wait times from presentation to treatment and survival in a population-based study

2016

Pancreatic survival is one of the worst in oncology. To what extent wait times affect outcomes in unknown No population-based study has previously explored patient and treatment delays among individuals with pancreatic cancer. The aim of this study was to estimate patient and treatment delays in patients with pancreatic cancer and to measure their association with survival in a nonselected population. All patients diagnosed with pancreatic cancer for the first time between 2009 and 2011 and registered in two French digestive cancer registries were included. Patient delay (time from onset of symptoms until the first consultation categorized into <1 or ≥1 month), and treatment delay (time bet…

Analysis of Possible Mechanisms Accounting for Raf-1 Kinase Inhibitor Protein Downregulation in Hepatocellular Carcinoma

2012

Abstract Raf-1 kinase inhibitor protein (RKIP) is a tumor and metastasis suppressor that promotes drug-induced apoptosis in cancer cells. It is frequently downregulated, both at the mRNA and protein level, in hepatocellular carcinoma (HCC), but the mechanisms leading to this reduction are obscure. We sequenced the whole RKIP gene in three human HCC cell lines (HA22T/VGH, HepG2, and Hep3B), and in five clinical HCC samples, but could not find any gene variant that might account for their low RKIP levels. We also examined whether gene methylation may be responsible for the altered RKIP expression. No methylation of the RKIP gene was found in the tumor samples, while among the cell lines only …
