Metastasis is the main cause of death in cancer patients and often epithelial-to-mesenchymal transition (EMT) is advocated as the basic mechanism. Recently Fang and colleagues described an EMT-independent process of metastasis in hepatocellular carcinoma (HCC): endothelium covers small cluster of tumor cells allowing tumor dissemination. This process of angiogenesis, named VETC (vessels that encapsulate tumor clusters) in HCC literature, has been described under different names in other cancer types. Furthermore, the investigators confirmed the negative impact of VETC on patients' prognosis on a large multicenter cohort of HCCs. Moreover, Fang et al demonstrated that patients affected by VETC-positive HCC benefit more from sorafenib therapy. Interestingly, this type of angiogenesis was also found in renal cell carcinoma, adrenal gland pheochromocytoma, thyroid follicular carcinoma and alveolar soft part sarcoma (ASPS) and associated to prognosis. Moreover, the distinction between benign and malignant neoplasms of the adrenal gland is a complex matter, being the established criteria still lacking a strong reproducibility. Several tyrosine kinase inhibitors are available for different cancer types; among them, HCC, RCC, ASPS, and TC may benefit from the so-called antiangiogenic tyrosine kinase inhibitors (aTKI) (such as sunitinib, sorafenib, pazopanib). A general (histotype-independent) validation of the prognostic role of VETC is missing. Moreover, inhibitors of tyrosine-kinase vascular endothelial growth factor receptors (VEGFR-TKI), represent an effective treatment for different cancer types, but predictive markers are still needed. In addition, novel systemic immunotherapy agents are being approved in many cancer types, as alternative to angiogenesis inhibitors. A broader frame including metastatic mechanisms, tumor microenvironment (TME, i.e. angiogenesis and immune infiltrate) and treatment response could answer to several needs currently unmet. Bayesian networks and causal models can be employed to effectively draw conclusions from retrospective data. The aim of the present study is to investigate in patients with RCC and adrenal carcinoma (AC) the VETC-expression on tumor tissue, correlating the results with clinical data, patients characteristics, and outcome.

The recent introduction of anti-PD-1 (nivolumab and pembrolizumab) and anti- PD-L1 (atezolizumab, durvalumab, avelumab) immune checkpoint inhibitors revolutionized oncological guidelines. Durable responses and prolongation of survival with these agents come at the price of the development of immune related adverse events (irAEs). Innovative tools are required in order to manage irAEs and to prevent their potential relapse, with the goal to improve the outcome of patients. In this regard, the Investigators aim to develop a multidisciplinary clinical pathway for cancer patients that are treated with immune checkpoint inhibitors.

Metastatic (HR-positive, HER2-negative) breast cancer (BC), advanced or unresectable neuroendocrine tumours of pancreatic (pNET), gastrointestinal or lung origin and metastatic renal cell carcinoma (mRCC) are diseases with poor outcome. Everolimus increases patients' median progression-free survival (PFS) with 4.6 months in metastatic BC (mBC), 7 months in (p)NET and 3 months in mRCC. However, serious adverse events (AEs) occur frequently. This reduces effectiveness of everolimus, because AEs are managed with dose reductions, treatment interruptions or even complete discontinuation of everolimus. Therapeutic-drug-monitoring (TDM) is used to adjust the prescribed daily dose, to maintain effective everolimus whole blood concentrations, with the lowest possible risk of AEs. While everolimus TDM has been common in transplantation medicine, it has not been implemented in oncology. The importance of TDM in oncology is supported by previous research which showed that a 2-fold increased everolimus whole blood trough concentration was associated with a short-term risk of grade ≥ 3 pneumonitis, stomatitis and metabolic events. Moreover, an exposure-toxicity relationship of everolimus in patients with thyroid cancer was observed, since initial everolimus concentrations could be associated with early toxicity (< 12 weeks, e.g. stomatitis). However, the association between initial everolimus measurements and long-term AEs (≥12 weeks, e.g. pneumonitis, anorexia and anemia) of any grade and the need for everolimus dose reductions could not be made. Since levels ±>18 µg/L were associated with toxicity, the investigators assume that the upper therapeutic window of everolimus in the oncologic setting will be ±18 µg/L. Similarly, a tendency to improved PFS and overall survival was observed when Cmin in steady state was above 14.1 μg/L. This seems to be the lower limit of the therapeutic window. Before consensus about the feasibility of everolimus TDM in the oncologic setting can be achieved, a number of questions (the knowledge gaps) need to be answered: 1. It is unknown whether everolimus whole blood trough levels (over time) predict long-term AEs. 2. The optimal concentration range for everolimus, with the treatment of mBC, mRCC, or (p)NET is unknown, especially the upper limit associated with toxicity. 3. It is unknown what everolimus concentration level is associated with the need for everolimus dose reductions.

Renal transplant patients have on average 3-5 times more risk of developing cancer than the general population. This rate can be increased up to 10 to 15 times in some type of cancer like kidney cancer. Among the identified risk factors, immunosuppressants and, in particular, calcineurin inhibitors (ciclosporin and tacrolimus) play a major role in increasing cancers apart from their depressant effects on the immune system. Calcineurin inhibitors (CCN) are the basis of immunosuppressive therapy in renal transplantation. Several mechanisms have been implicated to explain their pro-oncogenic properties. One related to an increase in VEGF expression seems particularly interesting in the study of renal cell carcinoma in the transplanted patient. Indeed, the physiopathology of kidney cancer has clearly been associated with an increase in the production of VEGF. Furthermore, some polymorphisms of the gene encoding VEGF have already been associated with the survival of patients with renal carcinoma and the circulating level of VEGF in the general population. The search for an association between the polymorphisms of the VEGF gene and renal carcinoma in renal transplant patients could thus identify patients whose risk of renal cell carcinoma (cRCC) post-transplantation is increased. If the involvement of certain polymorphisms in the development of cRCC was confirmed in this population, their research before the introduction of the immunosuppressive treatment would make it possible to direct the choice of treatment towards molecules without pro-oncogenic property in the Patients such as mTOR protein inhibitors (sirolimus, everolimus). This research project is therefore in line with the desire to move towards a more "personalized" medicine that could be beneficial for the patient.

The purpose of this study is to investigate if 14 weeks of pazopanib therapy prior to surgery (nephrectomy) is of benefit to patients with metastatic renal cancer. Ninety-five patients will be recruited into his study.

This laboratory study is looking into biomarkers in samples from younger patients with kidney cancer. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat cancer.

T Cell Receptor-engineered T-cell therapy (TCR T-cell therapy) offers a potentially transformative approach to treating cancer, but is currently limited by the lack of known targets (Maus and June, 2016; Ping et al., 2018). Arguably the most clinically meaningful way to discover new targets and TCRs for TCR T-cell therapy is to study the tumorinfiltrating lymphocytes of patients that are actively responding to immune checkpoint inhibitor (ICI) therapy. These T cells are clonally expanded as a result of checkpoint inhibition and are responsible for the patient's clinical response. The goal of this study is to acquire tumor and blood samples from up to 40 patients with renal cell carcinoma (RCC) malignancies who respond to ICI therapy. T cells will be isolated from these samples and the targets of their TCRs determined using TScan's genome-wide, high-throughput target ID technology. The expected outcome of this study is the discovery of a collection of new targets for TCR T-cell therapy, along with associated TCRs that will then be developed as novel therapies for patients with similar malignancies.
