Bhatt A, Stepanyan A, Al-Niaimi A et al. Principles of cytoreductive surgery for primary and metastatic peritoneal malignancies—the PSOGI–ESGO–ISSPP Lyon consensus. The Lancet Oncology, 27, e181-e194
Overview
This article brings together an international group of experts to establish clear, consistent guidance on how to perform cytoreductive surgery, a complex procedure used to treat cancers that have spread within the abdominal lining (the peritoneum). These cancers can include ovarian, colorectal, appendiceal, and others.
The goal of this work is to ensure that patients receive high-quality, standardized care regardless of where they are treated.
What is cytoreductive surgery?
Cytoreductive surgery is an operation in which surgeons remove as much visible cancer as possible from the abdomen.
The primary goal is to achieve what doctors call a complete macroscopic resection, meaning no visible tumors remain after surgery. This procedure is often combined with other treatments, such as chemotherapy delivered directly into the abdomen.
Why was this study needed?
Until now, there has been variation in how this surgery is described and performed across different hospitals and countries.
These differences can make it difficult to:
Compare outcomes between treatment centers
Train surgeons consistently
Ensure all patients receive the highest standard of care
This study was conducted to create shared definitions and recommendations that can be used worldwide.
What did the researchers do?
An international panel of experts collaborated to:
Define standard terminology for describing the surgery
Outline key surgical techniques and steps
Clarify how to measure whether a surgery is successful
Provide guidance that applies across multiple cancer types
Key findings
The most important goal of cytoreductive surgery is the complete removal of all visible cancer.
Standardized terminology and techniques are essential for improving communication among healthcare providers.
Consistent approaches can help improve patient outcomes and support better research.
What this means for patients
For patients being considered for cytoreductive surgery, this work helps ensure that:
Surgeons are following agreed-upon best practices
Care is more consistent across treatment centers
Outcomes may improve as techniques become more standardized
Bottom line
This article does not introduce a new treatment. Instead, it provides international guidance to make an important cancer surgery more consistent, safer, and more effective for patients around the world.
