Phase III randomised trial comparing intense dose-dense chemotherapy to tailored dose-dense chemotherapy in high-risk early breast cancer (GAIN-2)

2021

Abstract Background The GAIN-2 trial was designed to identify a superior intense dose-dense (idd) strategy for high-risk patients with early breast cancer. Here, we report an interim analysis, at which the predefined futility boundary was crossed. Patients and methods GAIN-2 was an open-label, randomised, multicentre phase III trial. Two thousand eight hundred and eighty seven patients were randomised 1:1 between three courses each of idd epirubicin (E) 150 mg/m2, nab-paclitaxel (nP) 330 mg/m2 and cyclophosphamide (C) 2000 mg/m2 (iddEnPC) versus four cycles of leucocyte nadir-based tailored and dose-dense EC (dtEC) followed by four cycles of tailored and dose-dense docetaxel (dtD) (dtEC-dtD…

The differentiation antigen NY-BR-1 is a potential target for antibody-based therapies in breast cancer

2007

Antibody-based cancer immunotherapy relies on the identification and characterization of target antigens and the development of potent antibodies recognizing the target. Here we report the expression analysis and molecular characterization of the differentiation antigen NY-BR-1, which we previously identified by using the SEREX (serological analysis of recombinant cDNA expression libraries) method. Corroborating methodologies, including mRNA quantitation and immunoblotting show that NY-BR-1 is strongly expressed in >70% of 129 breast tumors. Application of a NY-BR-1 specific antibody demonstrated NY-BR-1 expression in primary and metastastic breast cancers. In contrast, most of the breast c…

Dynamic intracellular survivin in oral squamous cell carcinoma: underlying molecular mechanism and potential as an early prognostic marker

2007

Survivin functions as an apoptosis inhibitor and a regulator of cell division in many tumours. The intracellular localization of survivin in tumours has been suggested as a prognostic marker. However, current reports are inconsistent and the underlying molecular mechanisms are not understood. The present study has examined the localization and prognostic value of nuclear and cytoplasmic survivin in the pre-therapeutic biopsies from 71 oral and oropharyngeal squamous carcinoma (OSCC) patients. Statistical analysis indicated that preferential nuclear versus cytoplasmic survivin correlated with favourable versus unfavourable disease outcome. Uni- and multi-variate analysis showed that in contr…

Inducible NO synthase confers chemoresistance in head and neck cancer by modulating survivin

2009

The dual role of the inducible NO synthase (iNOS) and NO signaling in head and neck squamous cell carcinoma (HNSCC) is a complex and can both promote or inhibit tumor progression. However, the underlying molecular mechanisms are not yet resolved in detail. We show for the first time that conditions, favoring low NO levels conferred resistance against cisplatin/taxol-induced apoptosis in HNSCC cell lines. Cytoprotection was mediated by survivin, because we observed its upregulation subsequent to low doses of the NO donors S-nitroso-N-acetyl-penicillamine (SNAP) and sodium nitroprusside (SNP) or ectopic expression of physiologic amounts of iNOS. Also, RNAi-mediated depletion of survivin block…
