Erratum to “Personalized peptide vaccine-induced immune response associated with long-term survival of a metastatic cholangiocarcinoma patient” (2016)

Personalized peptide vaccine-induced immune response associated with long-term survival of a metastatic cholangiocarcinoma patientJournal of HepatologyVol. 65Issue 4PreviewCholangiocarcinomas (CCA), heterogeneous malignant epithelial tumors originating from hepatic ductal cells, are typically diagnosed in a late stage and have a particularly poor prognosis [1]. CCA are rare in the Western world (0.5–1.5/100,000 persons), while they are the second most frequent primary liver cancer worldwide [2]. Risk factors include liver cirrhosis, viral hepatitis, hepatobiliary flukes and primary sclerosing cholangitis [1]. A recent systematic meta-analysis of 4,756 patients with intrahepatic cholangiocarcinoma (iCCA) reported 5-year survival rates between 5 and 56% and a median survival of 28 months [3].

The error concerned the labelling and orientation of Fig. 3B, which was not correctly reflected in the respective figure legend. Please find the corrected legend and Fig. 3 below. During further scrutiny, the authors noticed a few minor typographical errors in the published article. The corrections are as follows: Page 850 – Materials and methods Next-generation-sequencing As part of a research project (IndividuaLIVER, approved by the Institutional Review Board at the University Hospital of Tübingen), WES of tumor and normal tissue was performed for L06/10, L04/12 and P03/13 (Fig. 1). In addition, the transcriptome of tumor tissue of L06/12 and P03/13 was sequenced.

In addition, the transcriptome of tumor tissue of L06/10 and P03/13 was sequenced. Mass spectrometry HLA ligands were immunoprecipitated from cryopreserved tumor tissues and liver tissue (L03/10) as previously described [12] using the pan-HLA class I antibody, W6/32 (manufactured in-house).

T cell in vitro immunomonitoring Responses to HLA class I peptides were monitored by IFN-γ ELISPOT and HLA-peptide multimer staining, while responses to HLA class II peptides and RGS-5 peptide were determined by IFN-γ ELISPOT and ICS (for IFN-γ, TNF-β, IL-2 and IL-10) (all techniques are elaborated in the Supplementary materials and methods).

Page 851 (Table 1) The column heading P03/12 in the published version, should read P03/13. Page 852 (Results) Vaccination, further clinical course and immunomonitoring; 4th paragraph T cell cytokine response was detected against CCND1 by IFN-γ ELISPOT (Fig. 3A) and was confirmed to be a CD4+ response by intracellular cytokine staining (ICS) (Fig. 3B left lower panel). Should have read: T cell cytokine response was detected against CCND1 by IFN-γ ELISPOT (Fig 3A) and was confirmed to be a CD4+ response by intracellular cytokine staining (ICS) (Fig. 3B top panel).
