The focus of the scientific program was on “Translating Science into Survival”. Talks covered the challenging areas in cancer immunology and immunotherapy. The full list of topics can be found in the meeting program.
At the moment cancer immunology and immunotherapy is a hot topic in the next generation of anti-cancer therapies. Lots of attention is given to checkpoint immunodrugs as it was proven by the prevalence of talks on this subject in the program. Indeed, this drug has great potential, but at the same time, it is not universal. About 50% of patients do not benefit from it.
What lessons have been learned from the talks:
Checkpoint immunotherapies are the main stream
Not all cancer patients would respond to immunodrug
Genetic landscape of a tumour and/or the patient may contribute to this, thus making beneficial to check genetics for this type of treatment
Immunodrugs work better in combination with conventional therapies such as chemotherapy.
The immune system can be tuned by a drug, but it will switch on compensatory mechanisms to balance the intervention.
This research institute was established in 1904 to support work of Paul Ehrlich, its first director and funded by the private foundation “Chemotherapeutisches Forschungsinstitut Georg-Speyer-Haus”. Paul Erlich is the Father of the chemotherapyconcept originally developed to treat diseases of bacterial origin. He reasoned that there should be a chemical compound that can specifically target bacteria and stop its growth. He developed Salvarsan, the most effective drug for treatment of syphilis until penicillin came onto the market.
Paul Erlich is also known for his contribution to cancer research. He and his colleagues actively experimented on how tumour originates and spread. They also tried to understand how immune system can beat cancer applying vaccination concepts.
The main challenge in treating high-risk neuroblastoma is to stop or control tumour spread and development of resistance to multiple chemotherapeutic drugs. Immunotherapy is one of the recent advances in our understanding how our immune system handles body invaders such as virosis, bacteria and now tumour cells. Immunotherapy holds great promise as a treatment option for neuroblastoma as well as for many adult cancers owing to the specificity of immune effector cells targeted to a tumour. Another advantage is a potential reduction in the systemic side effects observed with other forms of treatment.
Immunotherapeutic approaches for neuroblastoma include the use of chimeric antigen receptor (CAR) T cells against both L1-CAM and ganglioside 2 (GD2) cell surface antigens to promote host antitumor response. Anti-GD2 antibodies bind GD2 and cause cell death by activating both complement-dependent cytotoxicity (CDC) and AB-dependent cellular cytotoxicity (ADCC) from natural-killer cells.
