Informazioni

CRS Report is a free, multilingual tool for documenting surgical procedures performed for patients with peritoneal malignancies. The tool enables fast and easy recording of the procedure details, exhaustive yet comprehensible documentation and facilitates clinical research

New tools

CRS Report offers surgeons, radiologists and pathologists a variety of tools to document the extent of peritoneal disease and the surgical procedures involved. These tools are available for free online use. Fillable PDFs of some tools are available for download to facilitate offline use

Morphological PCI

CRS Report enables capturing of the morphological peritoneal cancer index (PCI). Based on the MORPHEUS study, the morphological PCI captures the morphological appearance of peritoneal malignancy in each region. The morphological PCI is a new research tool that should improving the understanding of the biology of peritoneal malignancy and reduce the heterogeneity in recording the PCI.

Operative report

The operative report is the first of its kind available for general use. It helps in capturing all various surgical procedures involving different organ systems in an exhaustive manner with all other operative details including a checklist for occult peritoneal spaces. The online format has provision for generating a diagrammatic representation of the surgical procedures which improve cognition and communication with patients and the multidisciplinary team

The Lyon Consensus

The Lyon Consensus (the PSOGI-ESGO-ISSPP consensus on cytoreductive surgery for peritoneal malignancies was carried out in two parts under the leadership of Olivier Glehen and Aditi Bhatt (on behalf of the PSOGI and ISSPP) and Artem Stepanyan (on behalf of the ESGO)

Part 1 — Peritonectomy procedures

The first part revised the 30-year-old classification of peritonectomy procedures devised by Paul Sugarbaker, the father of cytoreductive surgery. All the new peritonectomy procedures were incorporated, and the subdivisions and boundaries of each procedure were defined.

The results were published in the BJS:

An exhaustive description of occult peritoneal spaces accompanied this publication:

Part 2 — Principles of cytoreductive surgery

The second part of the consensus focused on the principles of cytoreductive surgery, aiming to establish common and disease-specific guiding principles and to reach a consensus on the technical nuances of the procedure.

The results were published in The Lancet Oncology:

This consensus led to:

  • Standardized nomenclature: the term “cytoreductive surgery” is endorsed as the preferred terminology for potentially curative procedures, replacing outdated terms such as “debulking surgery”.
  • Technical principles: clear recommendations on the extent of peritoneal resection, visceral resections and lymph node management, tailored to the most common primary and secondary peritoneal malignancies.
  • Patient-centric approach: emphasis on conservative, biology-informed strategies that consider disease distribution and patient-specific factors.

Global collaboration through the Lyon Consensus

This consensus provided a unified framework to reduce the heterogeneity in the nomenclature and extent of peritonectomy procedures and the variability in surgical techniques, which should improve patient outcomes and support high-quality clinical trials.

The working group comprised most of the pioneers of cytoreductive surgery from different parts of the world, together with the surgeons with the largest experience in performing this surgery.

  • PSOGI: Brendan Moran, Marcello Deraco, Dennis Chi, Shigeki Kusamura, Kiran Turaga, Ahmed Al Niaimi, Alvaro Arjona Sanchez, Joel Baumgartner, Willemien Van Driel, Vincent Lavoue, Vivek Sukumar
  • ESGO: Jalid Sehouli, Christina Fotopoulou, Ignacio Zapardiel, Gwenael Ferron, Ane Gerda Zahl Eriksson, Donal Brennan, Francois Planchamp
  • ISSPP: Laurent Villeneuve, Kurt Van Der Speeten, Vahan Kepenekian, Naoual Bakrin

The consensus unified two surgical communities — the surgical oncology or peritoneal surface malignancy specialists belonging to the PSOGI and ISSPP, and the gynaecological oncologists belonging to the ESGO. In part 1 of the consensus, 141 experts from 5 continents participated in the Delphi exercise, while in part 2, 148 experts from 6 continents participated.
