After the 16th edition held in 2021 in digital format, a new edition of the IBSA Foundation Special Forum, entitled "Personalized therapy in oncology" took place on 16 June 2023 in the auditorium of the Università della Svizzera italiana (USI) as part of the programme of the 17th International Conference on Malignant Lymphoma (ICML).
The ICML is one of the most important international events in the field of lymphoid neoplasm research and treatment, organised by Professor Cavalli and the Foundation for the Institute of Oncology Research (IOR), in cooperation with the American Association for Cancer Research (AACR) and in collaboration with the European School of Oncology (ESO).
Oncological research is making great strides
Until a few years ago tumors originating from the same type of cells were considered and treated as if they were the same disease, today thanks to the interdisciplinary work of doctors and to techniques that allow increasingly detailed resolution, we know that cancer is a highly dynamic disease with a high degree of heterogeneity not only at the intra-tumor level but also between patient and patient.
At the same time, the ever more complete characterization of recurrent DNA alterations in cancer patients and the discovery of new tumor mechanisms allowed the development of highly precise therapies capable of targeting specific molecular targets.
Personalized oncological therapy fits into this complex context where each patient is treated on the basis of the specific molecular characteristics of his tumor. Molecular target therapies are already a reality: for example, they are used for the treatment of some types of breast cancer, gastrointestinal stromal tumors or chronic myeloid leukemia. These are promising therapies tailored to the genetic characteristics of the patient. Scientific research is working tirelessly to understand how to apply this approach to a larger number of tumors, study the mechanisms of resistance and develop less invasive and more detailed diagnostic tests.
The IBSA Foundation Special Forum aims to discuss the latest discoveries and the objectives of personalized oncological medicine with international experts.

Abstract
- Organoids model human disease
Hans Clevers, Basel (Switzerland)
Organoids are 3D structures that are established from either pluripotent (iPSC/ES) or adult stem cells and capture key characteristics of the represented organ, in terms of architecture, cell type composition, physiology and pathology. In this seminar, I will discuss the development of adult-stem cell based organoids and will discuss a number of human disease models-in-a-dish that are based on gut, lung, breast and liver organoids. - Unconventional approaches to cancer therapy
René Bernards, Amsterdam (Netherlands)
Single-agent cancer therapeutics can initially be highly effective, but resistance remains a major challenge. Combining drugs can help avoid resistance, but the number of possible drug combinations vastly exceeds what can be tested clinically, both financially and in terms of patient availability. Rational drug combinations based on a deep understanding of the underlying molecular mechanisms associated with therapy resistance are potentially powerful in the treatment of cancer. In my lecture I will discuss several innovative ways to combine drugs to produce longer-lasting responses in patients. Examples will include synthetic lethal drug combinations, sequential treatment regimen and our very recent approaches to hyperactivate oncogenic signalling in cancer cells as a therapeutic strategy. - Patient-specific models of multicellular oncogenic competence in metastasis
Arianna Baggiolini, Bellinzona (Switzerland)
Oncogenic competence is related to cell fate and cell state, but those are not only cell-intrinsic processes, as they are greatly regulated by the cell extrinsic factors, as the other cells in the microenvironment, and by systemic hormonal and metabolic influences.
Among the possible metastatic sites, the brain is characterized by distinct metabolic conditions and immune environment. Moreover, the brain is composed of unique cell types as neurons and cells of the glia, like astrocytes and microglia. The study of the human brain microenvironment has always been challenging because of the problematic access to human brain samples, arduous cellular isolation, and culture. The human pluripotent stem cells (hPSCs)-based technologies allow us to build patient-specific 3D brain organoids and address how cancer cells adapt to and remodel the human brain niche.

Arianna Baggiolini, Bellinzona (Switzerland)
Patient-specific models of multicellular oncogenic competence in metastasis
Dr. Arianna Baggiolini is a Group Leader at the Institute of Oncology Research of BIOS+ in Switzerland. Arianna studies melanoma, the most aggressive skin cancer. She is interested in defining how developmental programs are reactivated during the acquisition of a malignant state and how they regulate tumor formation and progression. Her lab, called Baggiolinilab, combines in vivo models and human pluripotent stem cell (hPSC)-based technologies to address how malignancy is regulated cell-intrinsically and depending on the microenvironment. Arianna has received a number of awards including the Tri-Institutional Breakout Price, the SNSF Starting grant and was elected Leading Edge Fellow 2021.
René Bernards, Amsterdam (Netherlands)
Unconventional approaches to cancer therapy
René Bernards is a professor of molecular carcinogenesis at the Netherlands Cancer Institute. His laboratory uses functional genomic approaches to find vulnerabilities of cancers that can be exploited therapeutically. His laboratory identified the FDA approved combination of a BRAF inhibitor and an EGFR inhibitor as effective for the treatment of BRAF mutant colon cancer. He also developed the first clinically used gene expression test for early breast cancer prognosis; MammaPrint.
He is a member of the Royal Netherlands Academy of Sciences, the National Academy of Sciences, the American Academy of Arts and Sciences and a fellow of the AACR Academy.
