Reproducibility and concordance of 4 clinically developed programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) assays in triple-negative brea…
2020
Abstract Background Atezolizumab (an anti–PD-L1 antibody) has shown clinical activity alone or in combination with nab-paclitaxel in patients (pts) with first-line metastatic TNBC who have PD-L1 expression on their tumour-infiltrating immune cells (IC). We analysed the performance of 4 PD-L1 IHC assays for PD-L1 IC expression in TNBC. Methods Thirty archival TNBC tissue specimens were selected from a set of 107 based on PD-L1 IC expression per VENTANA SP142 ( 5%: 8 cases), to represent the distribution of PD-L1 IC–positivity in the pivotal atezolizumab studies (Emens et al., SABCS 2018; JAMA Oncol 2019). Serial histologic sections were stained with VENTANA SP142 and SP263, and DAKO 22C3 and…

Angioimmunoblastic T-cell lymphoma
2008
Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive neoplasm clinically characterized by sudden onset of constitutional symptoms, lymphadenopathy, hepatosplenomegaly, frequent autoimmune phenomena, particularly hemolytic anemia and thrombocytopenia, and polyclonal hypergammaglobulinemia. The lymph node histological picture is also distinctive, constituted by a polymorphic infiltrate, a marked proliferation of high endothelial venules, and a dense meshwork of dentritic cells. The neoplastic CD4+ T-cells represent a minority of the lymph node cell population; its detection is facilitated by the aberrant expression of CD10. Almost all cases arbor an EBV infected B-cell populatio…
The CpG island methylator phenotype in breast cancer is associated with the lobular subtype
2014
Background: Aberrations in DNA methylation patterns are well-described in human malignancies. However, the existence of the ‘CpG island methylator phenotype’ (CIMP) in human breast cancer is still controversial. Materials & methods: Illumina's HumanMethylation 450K BeadChip was used to analyze genome-wide DNA methylation patterns. Chromosomal abnormalities were determined by array-based CGH. Results: Invasive lobular breast carcinomas exhibit the highest number of differentially methylated CpG sites and a strong inverse correlation of aberrant DNA hypermethylation and copy number alterations. Nine differentially methylated regions within seven genes discriminating the investigated subg…
