Dear colleagues, dear friends


It represents a real honor and a real challenge to welcome you in Lyon for the first congress that will join forces from the Peritoneal Surface Oncology Group International (PSOGI) and the International Society for Study of Pleural and Peritoneum (ISSPP), the two major International Organizations dedicated to the management of Peritoneal Surface Malignancies (PSM). We really hope that this first initiative will facilitate future collaborations and common research of both to improve the management of this challenging evolution.

The principal key word of this event will be “Multidisciplinary” around the peritoneum, as attested by the support of five vice-presidents: one colorectal PSM surgeon, Vahan Képénékian, one  ovarian PSM gynecologist, Naoual Bakrin, one Radiologist, Pascal Rousset, one Pathologist, Frederic Bibeau, and one Surgeon Researcher, Marc Pocard. The best international pioneers of PSM management as well as international leaders in medical oncology, pathology, radiology, biology, translational research and artificial intelligence will be invited.

Of course, cytoreductive surgery, HIPEC, PIPAC will be central points discussed and debated for all PSM, but large place will be established for debate on perioperative oncologic management and maintenance therapy with medical oncologists, on morphologic evaluation and radiomics of peritoneum with radiologists, on biologic, molecular, genetic, pathologic features and pathomics with biologists and pathologists, on new challenges including Big Data and Artificial Intelligence, on new loco-regional treatments (nanoparticles, CART cells, immunotherapy, virotherapy), and on perioperative overall management including questions of prehabilitation, early postoperative recovery, patient’s preferences and quality of life. Sessions will include multidisciplinary speakers and chairmen and will be established to stimulate discussions and debates.


Union makes forces and we really hope this congress will be an important step underlining multidisciplinary talents and collaborations around Peritoneal Surface Malignancies.

Olivier Glehen,

President of the Congress
