Precision oncology in glioblastomas and the evolution of personalized therapies
The prof. Daniele Generali.
Glioblastoma multiforme: a complex oncological challenge
Glioblastomas, among the most aggressive and difficult to treat brain tumors, represent approximately 20% of brain tumors.
To address this challenge, precision oncology has led to a true revolution in the treatment of brain tumors. Professor Daniele Generali, an internationally renowned oncologist, is one of the leading experts in this field.
Graduated in Medicine and Surgery from the University of Brescia, Professor Generali continued his specialist training with a Diploma in Medical Oncology and a Master in Molecular Oncology at the University of Turin, finally completing a doctorate (DPhil) in Molecular Oncology at the University of Oxford, UK.
Currently, in addition to being Associate Professor in Medical Oncology at the University of Trieste, he also holds the position of Professor at the Catholic University of the Sacred Heart.
In this interview he illustrates the evolution of oncological therapies, in particular in the treatment of glioblastomas, and the importance of molecular tests, many of which are conducted in the genetics laboratory MAGI’S LAB of Rovereto.

Professor, what exactly is a glioblastoma and what are the main difficulties in treating it?
«Glioblastoma multiforme is an extremely malignant brain tumor that originates from astrocytes, cells of the central nervous system. It is known for its rapid growth and ability to infiltrate healthy brain tissue, making it difficult to completely eradicate.
«Another important challenge is the genetic variability within the tumor itself: cells within a single glioblastoma can have different mutations, which makes choosing an effective therapy complex.»
What are the main causes that contribute to the development of brain tumors?
«Glioblastoma (GBM), the most common and aggressive malignant brain tumor, is characterized by a complex and multifactorial etiology. The main causes that contribute to the development of glioblastoma include:
1. Genetic alterations: Glioblastoma is associated with numerous genetic mutations, many of which involve genes regulating critical cellular pathways such as proliferation, apoptosis and DNA repair. The most common mutations include alterations in the TP53 gene, mutations in the IDH1 and IDH2 genes, and loss of function of the tumor suppressor gene PTEN. Amplification of the EGFR gene is present in approximately 40% of glioblastoma cases and leads to aberrant epidermal growth factor receptor signaling, promoting uncontrolled growth of tumor cells.
2. Hereditary genetic factors: Although most cases of glioblastoma are sporadic, there are hereditary genetic syndromes that predispose to its development. Among these, Li-Fraumeni syndrome (caused by mutations in the TP53 gene) and neurofibromatosis type 1 (mutations in the NF1 gene) increase the risk of developing gliomas, including glioblastomas.
3. Exposure to ionizing radiation: Radiation therapy to the cranial level, used to treat other brain or extracranial tumors, is a recognized risk factor for the development of glioblastoma. The risk appears particularly high in patients treated at a young age.
4. Aging: Glioblastoma is predominantly diagnosed in older individuals, with a higher incidence in individuals over 60 years of age. The aging process is associated with a decrease in DNA repair capacity and an accumulation of somatic mutations, which may contribute to malignant transformation.
5. Epigenetic and microenvironmental factors: Recent studies have highlighted the role of epigenetic alterations, such as methylation of the MGMT (O6-methylguanine-DNA methyltransferase) gene promoter, which is associated with a reduced DNA repair capacity and increased sensitivity to alkylating agents . Furthermore, the tumor microenvironment, characterized by marked hypoxia and chronic inflammation, favors the proliferation of tumor cells and resistance to therapies.
6. Environmental and occupational factors: Although the evidence remains inconclusive, some research suggests that exposure to toxic chemicals, such as pesticides and solvents, may be associated with an increased risk of glioblastoma. However, these correlations require further studies to be validated.
«In summary, glioblastoma develops following a complex interaction between genetic alterations, environmental and microenvironmental factors, with molecular and cellular mechanisms still being studied. Research continues to investigate new factors that may contribute to tumor development.”
Precision oncology has revolutionized the treatment of many cancers. How does this approach apply to glioblastomas?
«Precision oncology has undoubtedly transformed the therapeutic approach into a personalized approach that allows us to analyze the molecular and genetic characteristics of the tumor, developing targeted treatments.
«In the case of glioblastomas, which are traditionally treated with surgery, radiotherapy and chemotherapy, precision oncology allows the identification of specific genetic mutations that can be targeted with specific drugs. For example, temozolomide is a chemotherapy drug that can cross the blood-brain barrier, but not all patients respond the same way. But, thanks to detailed molecular profiling, we can identify who will benefit most from this therapy.
«In this context, the MAGI’S LAB laboratory in Rovereto plays a central role. With the help of advanced molecular tests that we conduct at this laboratory, we are able to map the genetic profile of the tumor and identify the mutations on which we can intervene. This significantly improves the personalization of therapies.»
What are the most promising drugs in development for the treatment of glioblastomas?
«In addition to temozolomide, there are numerous ongoing studies on innovative therapies, such as inhibitors of the PI3K/AKT/mTOR pathway, which target key cellular mechanisms for tumor growth.
«In addition, we are also exploring the use of angiogenesis inhibitors, which limit the formation of new blood vessels necessary for tumor growth.
“This is an ever-evolving field, and the hope is that by combining multiple targeted treatments, we can achieve better outcomes than using each therapy alone.”
How important is immunotherapy and the use of CAR-T cells in glioblastomas?
«Immunotherapy has radically changed the treatment of many tumors, but in glioblastomas the results have so far been limited, mainly due to the tumor’s ability to evade the immune system. However, we are exploring new possibilities, such as the use of CAR- T cells, which involves genetically modifying the patient’s T lymphocytes so that they recognize and attack tumor cells. Although we are still in the early stages of testing, the preliminary results are promising.”
How has the early diagnosis of glioblastomas evolved and what are the most advanced diagnostic techniques?
«Early diagnosis is crucial, but glioblastomas are often detected only when symptoms become evident, and by that point the tumor is already in an advanced stage.
“Magnetic resonance imaging (MRI) with contrast remains the main diagnostic tool, but we are exploring new techniques such as functional MRI and PET, which can identify the tumor earlier and better distinguish healthy brain tissue from diseased brain tissue.”
Professor, what are your future prospects for the treatment of glioblastomas?
«The future lies in the further development of precision oncology as our understanding of the genetic and molecular mechanisms of glioblastomas expands, we are able to develop increasingly targeted therapies.
«The treatment combination of surgery, radiotherapy, targeted drugs and immunotherapy is demonstrating promising results. The use of new technologies such as anti-tumor vaccines and nanotechnologies could open up further possibilities in the near future.”
Thanks to advances in precision oncology and advanced diagnostic technologies,
The treatment of glioblastomas is making significant progress.
The work of Professor Daniele Generali, with a career shaped by international excellence and top-level academic institutions, represents a beacon of hope for patients suffering from this serious disease.
Under his leadership, advanced molecular testing and personalized therapies are emerging as the way to improve the chances of success in the treatment of these complex malignancies.
