On Friday 29 October, we inaugurated our new CT laboratory at BioClinicum, adjacent to Karolinska University Hospital in Solna. In addition to a tour of the laboratory and an ensuing reception, several speeches were given on the significance of the new CT laboratory. The following is an excerpt from the speech given by the chief executive officer of Karolinska University Hospital, Björn Zoëga.

“The CT technology that became available during the 1970s opened up a whole new world for us doctors. This, the next stage in development, offers unbounded possibilities. Here at Karolinska University Hospital, in various ways we treat 1.3 million patients every year. Our aim is that the hospital should constantly progress and provide better care and treatment and I believe that we have demonstrated that we can do so. The fact that we are now the first in the world with this new technology also affirms both that Karolinska Institutet is ranked among the best environments for clinical research in the world, and that Karolinska University Hospital is advancing as one of the best hospitals in the world.

Our machinery and its relationship to how we work as Europe’s smartest hospital means that we must constantly move forwards. To do so together with others is a success factor, and the CT laboratory is an excellent example of this. The strength in working together has been made particularly apparent during the pandemic. It means a great deal to the hospital and the hospital’s patients that clinical studies are now underway to ensure that the next generation of computed tomography benefits patients and the health service.”

Awarded with Swedish Research Counicil's starting Grant within Natural and Engineering Sciences. MedTechLabs fellow, Mats Persson is awarded as a junior researcher to establish himself as independent researcher in Sweden. The 4-year grant amounts to SEK 4 000 000.

The grant is directed to the project “Highly accurate spectral photon counting CT for improved cancer diagnosis”

Cancer is one of the leading causes of mortality with an expected 10 million deaths annually. A very widely used imaging modality for diagnosing cancer is x-ray computed tomography (CT), which provides three-dimensional images of the human body is reconstructed from x-ray measurements. Despite its high usefulness, there are limitations with the current CT technology with respect to diagnostic quality and quantitative accuracy. The emerging photon-counting CT technology can overcome these limitations with its higher spatial resolution, lower image noise, and improved material-selective imaging.

To achieve the full potential of the technology, new image reconstruction methods need to be developed. Deep-learning-based image reconstruction, a new technology for image CT reconstruction, has demonstrated substantial image quality improvement and fast reconstruction. We will develop a deep-learning-based CT image reconstruction method for generating highly accurate photon counting images together with maps of image uncertainty, using a CT scanner prototype developed in our lab.

We will evaluate the usefulness of the new imaging technique for diagnosis and radiomic characterization of tumors. The anticipated outcome is that photon-counting spectral CT with deep-learning reconstruction can give drastically improved diagnostic quality and radiomic measurement accuracy without extra dose. This can lead to saved lives and new research avenues in the field of data-driven cancer diagnosis.

The grant is directed to the project “Tearing down the walls of brain cancer: delivery of radiopharmaceuticals across the blood-brain barrier”

One in three children that suffer from brain cancer dies before reaching adulthood. Standard treatment generally involves the opening of the skull for physical removal of the tumour, often in combination with several cycles of chemo- and/or radiotherapy. Brain surgery is highly invasive and comes with significant risks. Risks include bleeding or blood clots in the brain, swelling, memory problems, seizures, infections, stroke, coma and impaired speech, vision, coordination or balance. Furthermore, it is often difficult for a surgeon to identify where the tumour ends and healthy tissue begins. Surgery is only effective when the tumour is fully removed, since an incomplete resection will lead to relapse, and decreases the survival chances of a patient. In the current project, we are developing an innovative, non-surgical treatment strategy that minimises side effects with a substantial chance of significant tumour reduction or complete tumour elimination.

A promising non-surgical treatment strategy: endoradiotherapy

In the field of endoradiotherapy, tumour-targeting molecules such as antibodies or peptides are labelled with radioactive isotopes to deliver a lethal dose of radiation to a tumour. These radiolabelled molecules are injected into patients with cancer to bind to tumour cells and irradiate the tumour from within. With this treatment, the number and size of tumours can significantly be reduced, which has led to a remarkable increase in survival rates. A major limitation in the scope of brain cancer, however, is that standard endoradiotherapeutic agents cannot cross the blood-brain barrier (BBB). This is a layer of tightly packed cells that separates the brain from the blood circulation to protect it from toxins and other pathogens. The first goal of this project is to design endoradiotherapeutic agents that can cross the BBB and target the brain tumour. As a first strategy, we are developing an innovative bispecific antibody that can be transported across the BBB to specifically bind to brain tumour cells. Here, we combine a tumour-targeting antibody with parts of a second antibody that enable transportation across the BBB. As a second strategy, we are using a peptide from scorpion venom, which is designed by nature to cross the BBB to target the central nervous system. In preclinical studies, this peptide has demonstrated an exceptionally high specificity for brain tumour cells.

Minimising side effects

Antibodies and peptides generally circulate in the body for multiple days. In the case of radiolabelled antibodies and peptides, this leads to undesirably high radiation doses to healthy tissues. Particularly in children, this may lead to significant side effects, such as impaired bone growth, calcium deficiency and toxicity to the haematopoietic system. The second goal of this project is to reduce side effects by separately injecting the bispecific antibody or peptide and the radioactive agent, which then chemically react to each other at the tumour site. The advantage of this pretargeting strategy is that long-circulating, unbound antibodies and peptides are cleared from the body before the radioactive agent is injected. This radioactive agent is cleared from the body rapidly, thereby minimising the radiation dose to healthy tissues. With this strategy, we aim to deliver a high therapeutic radiation dose to the brain tumour, while minimising the side effects caused by radiation to the rest of the body.

Innovative research

Our research integrates recent advances in radiology, oncology, chemistry and molecular biology into innovative research designs and novel treatment strategies. This project will open up new fields of research and allow children with brain cancer to benefit from the exceptional proven clinical advantages of endoradiotherapy, with minimal side effects. The newly designed methodologies and agents could lead to breakthroughs in key applications of fundamental, preclinical and clinical interest and change the way we approach illnesses of the brain.
