With nine others, he had been selected from 72 applicants to contribute to Oncode Institute's mission: to accelerate breakthroughs…

A cancer pill, preferably without severe side effects, is something we’d all welcome. Is it a matter of time before such a pill is a reality? We put this question to three Leiden researchers and asked how they themselves are contributing to new cancer treatments.

Chemotherapy that does nothing until you irradiate it with light. Sylvestre Bonnet receives a Vici grant of 1.5 million euros for the development of this treatment. The Leiden chemist wants to build a new molecule to fight tumours that are at the time still difficult to treat.

In 2013, Sylvestre Bonnet received an ERC Starting Grant to kill cancer with molecules that can be activated by light. Two postdocs and three PhD students later, the end approaches of his so far successful project.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

Researchers of the Leiden University Medical Centre (LUMC) and the Leiden Institute of Chemistry have made an important discovery about the commonly used anti-cancer drug doxorubicin. They have found a way to reduce its side effects without sacrificing the effectiveness of the medication. This is encouraging…

Patients with incurable cancer want their oncologist to be clear but to show empathy too. They find hard and vague communication harmful. These are the results of a study by psychologists from Leiden that has been published in the American journal Cancer.

On 11 November Professor of Gastroenterology and Hepatology, Monique van Leerdam will deliver her inaugural lecture entitled, ‘Aiming for Prevention’. Van Leerdam, who specialises in hereditary tumours, was appointed professor in July 2020. In her inaugural lecture she will discuss the importance of…

Leiden researchers have developed a groundbreaking model to advance cancer immunotherapy. Using a 3D printer, they create mini-tumors within an environment that closely mimics human tissue. They have also developed a method to monitor real-time interactions of these mini-tumours with immune cells during…

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…
