PSOGI conference 2023

A  delegation of  10 with both clinicians and researchers from Oslo University Hospital attended the 13th International Congress on Peritoneal Surface Malignancies in Venice, October 4th – 6th, 2023. The conference had a lot of exciting presentations with different practice experiences and cutting-edge scientific knowledge, and there was a lot of opportunity to talk to long-standing and new international colleagues and collaborators.

The Oslo team had three oral presentations  Dr Stein Larsen with the title; ”18-month safety and efficacy after intraperitoneal treatment with 224Radium-labelled microparticles (Radspherin) after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for colorectal peritoneal metastasis (PM)” . The aim of this study has been to clearify if Radspherin  a radiopharmaceutical drug , given intraperitoneally  post-surgery can  induce efficient  killing of remaining  tumor cells . The safety results showed that the drug is well tolerated  and also showed promising results indicating reduction in peritoneal metastasis at 18 months. Dr Larsen concluded that further exploration of these encouring results is planned  in a randomized controlled trial.

 Dr Kjersti Flatmark had an encourage presentation on the ongoing  PSeudovax project with the title  “Pseudovax - a therapeutic cancer vaccine targeting mutated GNAS in PMP” .  Dr Flatmark gave an update on the project  where the most important update might be that the Polypeptide is in production and hopefully delivered start of next year, and that the plan is two start up with inclusion at the end of next year. 

The last of our presenters were Dr Karianne Giller Fleten  with the title  “A novel nanoparticle-based platform for intraperitoneal treatment of peritoneal metastases from ovarian and colorectal cancer “. Dr. Fleten showed some exciting results with nanoparticles that encapsulated cabaxitaxel increases retention and treatment responses in peritoneal metastases from ovarian and colorectal cancer.

We also had 4 posters presenting  some of our ongoing projects see Picture 2.
