    This consortium aims to validate technologies for CTCs, cfDNA and circulating microRNAs as blood-based biomarkers to determine the absence/presence of drug targets and/or assess response to treatment in NSCLC (large indication) and Her2RMBC (small indication). The validated assays will be deployed in controlled prospective clinical studies and compared with immune-phenotype and molecular data obtained from tumour biopsies and correlated with patient responses to therapy.

    Current therapeutic strategies in particular for NSCLC are chemotherapy and drugs targeting specific molecular targets and pathways. The number of specific targets is increasing and about a third of non-squamous cell lung carcinomas especially adenocarcinomas have specific targets. Since these therapeutic targets are only expressed in a subset of tumours the development of companion diagnostics that can be used for stratification and/or monitoring of these therapies in individual patients is of utmost importance for future drug development.

    Breast cancer is the most common malignancy in women, and although several therapeutic options are already available (e.g., chemotherapy, endocrine therapy, antibodies, etc.), resistance to these therapies significantly limits the success rates. In CANCER-ID, we will therefore focus on breast cancer patients who failed to respond to HER2-targeted therapies.HER2 is the most prominent molecular target in breast cancer and it defines a clear molecular subtype. Both lung and breast cancer comprise of approx. 800,000 new cases in the EU and these two tumour types are responsible for more than 50% of cancer-related deaths in women.

    Blood-based companion diagnostics will be important to improve systemic treatment and to design new clinical trials in these patients. When implemented in clinical practice it will result in personalized medicine by adapting the therapies to the individual risk of the cancer patient. Important challenges for all circulating biomarker developments are assay sensitivity, specificity, standardization and validation. Standard operating procedures (SOPs) are, however, generally lacking and will be provided and introduced by CANCER-ID.

    The CANCER-ID partners comprise a unique network of experts in the fields of tumour biology, biomarker development, clinical sciences and bioinformatics. Members of this consortium are all internationally recognized for their work on CTCs, cfDNA and circulating cell free microRNA (cfmiRs), and have implemented liquid biopsies in clinical research studies. In addition, regulatory agencies (EMA/FDA) and patient advocacy group (Mammazone) are involved from the beginning of the project. The coordinators of this consortium have coordinated FP6/FP7 EU consortia and published seminal reports on disseminating tumour cells.

  • Liquid biopsy: In vivo capturing and molecular characterization of circulating tumor cells as a novel tool for improving tertiary prevention in breast cancer

    The described deficiencies of current CTC assays have generated skepticism in the medical community about the reliability of current CTC testing, which is part of the reasons why CTC analyses are still not recommended for patient management by medical associations (e.g., ASCO). The CE-certified nanowire device developed by the SME GILUPI has the potential to solve the main obstacles of CTC testing.

    The project will strengthen the existing collaboration between the Greek and German partners (see below) and has the following specific objectives:

    • Increasing the yield of CTCs by analysis of large amounts of blood (1.5 L) using in vivo CTC cap-ture as a novel approach;
    • Implementation of new cell surface antigens that will capture in vivo CTCs undergoing an epithelial-mesenchymal transition;
    • Development of reliable assays for molecular and genetic characterization of CTCs;
    • Addressing the key question of a liquid biopsy as to whether CTCs resemble the corresponding primary tumors in non-metastatic patients at primary diagnosis or distant metastases in patients at the time of metastatic relapse.

    Breast cancer will serve as model disease, since CTC testing has been widely implemented and clini-cal results for the first nanowire product are available for this cancer entity.

    This project is aimed to validate the number of CTCs isolated from patient’s blood as a prognostic marker for relapse in high-risk prostate cancer (PCA) patients treated with primary radical prostatectomy or radiotherapy. CTC isolation and enumeration will be realized by three different assay formats in comparison.

    • Isolation of CTCs from blood samples using CellSearch® as the current “gold standard” for CTC detection,
    • EPISPOT assay that detects viable CTCs and
    • GILUPI nanodetector that captures CTCs in vivo.
    The isolated CTCs will be further characterized by molecular techniques. The numbers of CTCs detected by each assay will be compared to PSA serum levels as the gold standard biomarker in PCA and to clinical outcome to identify the CTC detection assay(s) with the best prognostic value.

    The systematic approach chosen in this project will validate CTC detection as a novel biomarker for predicting clinical outcome in PCA patients. A validated procedure for CTC detection and characterization will improve risk assessment and contribute to a better stratification of PCA patients to future adjuvant therapies adjusted to the individual risk of each cancer patient.

    The joint project will develop a system to isolate and individually characterize circulating tumor cells (CTCs).

    "Using a microfluidic system, the isolation of CTCs from blood will be largely automated and standardized allowing robust and accurate counting of the isolated cells as well as further characterization on a molecular and single-cell level. This will be realized by the interdisciplinary collaboration of affiliates with long-standing expertise in the fields of cancer biomarkers, clinical CTC-analysis and microfluidic-based technology products. The projected system addresses current challenges in biotechnology and healthcare. The prognostic relevance of the number of CTCs that can be detected in blood of cancer patients is well documented. Although solutions currently available on the market allow CTCs to be counted using specific marker antigens, these closed systems do not allow further molecular analysis of the isolated cells. The projected system will be able to detect, sort and isolate CTCs and, additionally, allow a subsequent molecular characterization of the recovered cells based on predictive/theranostic markers. This may facilitate optimal patient therapy selection and monitoring during therapy in addition to prognostic statements based on CTC-counts."
