Detailed Description
The main aim of anticancer therapies is to exert cytotoxic effects on cancer cells. It recently emerged that some anticancer therapeutic modalities are capable of inducing a cell death subroutine called immunogenic cell death (ICD) that can mediate specific, sustained anticancer immunity. These observations have marked the beginning of intense research into immunoadjuvant or anticancer immunity inducing "side-effects" associated with anticancer therapies.
At present, in humans, no ICD-associated predictive biomarkers have been identified, which hampers the development of immunological strategies. No published data about human biomarkers for ICD is available.
In vitro, ICD has been found to be associated with the spatiotemporally defined emission of danger signals such as surface exposed calreticulin (CRT) or heat shock protein 90 (HSP90), secreted ATP and released TLR4 agonists like HMGB1 or HSP70. Moreover, recently it has emerged that ICD may also be associated with a "viral response-like chemokine signature (VCS)" capable of acting as both 'find me' signal (for granulocytic myeloid cells) and 'keep away' signal (for immature monocytic myeloid cells) - further details of this paradigm are under investigation.
Thus, the presence of these molecular determinants of ICD can be used to monitor the host immune status and as a predictive biomarker. Examples include: danger signals as surrogate positive biomarkers (HMGB1, HSP70 and autoantibodies against CRT/HSP90); viral-response like chemokine signature as direct positive biomarkers (IFN1A, IFN1B and CXCL10>CCL2>CXCL1).
The presence of determinants of ICD can be confirmed through the strategy of following biomarkers (in non-hematological cancers):
- Cancer cell-associated pro-tumorigenic cytokines/factors IL1A, IL10, IL6, TGF-B, VEGFA, VEFGC, IDO enzyme, CXCL12, IL8
- Immune cell-associated pro-tumorigenic cytokines/chemokines/factors IL10, IDO enzyme, TGF-B, IL4, IL5, IL13, TNF, M-CSF, GM-CSF, IL26, CXCl5, CCL7
- danger signals as surrogate positive biomarkers HMGB1, HSP70 and autoantibodies against CRT/HSP90
- Cancer cell-associated viral response-like chemokine signature IFN-a, IFN-b, CXCL9, CXCL10, CXCL1 and CCL2
- Immune cell-associated anti-tumorigenic cytokines or chemokines as positive biomarkers IL1B, IL12p70, IL15, IFNG, IL22, IL23, IL17A, IL2, CCL4, CCL5, CXCL13, CCL8, CCL19, CXCL11,CCL12, CCL17, CCL23, CCL22, CCL13, CCL24, CCL1, CCL26, CXCL2, CXCL16 Moreover, the investigators will also investigate serum-associated exosomes as possible biomarkers of an efficient antitumor response. Compared to certain soluble biomarkers (which are accessible and thus more susceptible to extracellular proteases), exosomal biomarkers can exhibit a longer half-life than their soluble equivalents, due to the "protection" provided by their encompassing lipid membrane. Therefore, the investigators are also interested in exploiting exosomes as a source of antitumor response information and as novel biomarkers of therapeutic success (those mentioned above and others under investigation).
Radiotherapy has been established through various robust lines of in vitro and in vivo evaluation to be capable of inducing ICD and anticancer immune responses. As an exploratory analysis, we will integrate lipidomics into the workflow. This has already been done in multiple disease settings and NSCLC has already proven to change lipid content in a quantifiable manner. The aim of this pilot study is to investigate the hypothesis that certain biomarkers of ICD that were identified in vitro or ex vivo are detectable in patient sera following radiotherapy and/or chemotherapy. Radiotherapy alone or concurrent cisplatin-doublet and radiotherapy will be investigated. The investigator will conduct this pilot study to gather initial data to build upon in future clinical trials, as there is no in vivo data available on this topic. Results will be published and used for future grant applications.
