BACKGROUND: Staging laparoscopy with peritoneal cytology and biopsies is recommended in selected patients with gastric cancer (GC), but practical guidance for assessment of peritoneal lavage/ascites and peritoneal biopsies is lacking. We aimed to develop consensus-based recommendations for handling, assessing and reporting of these specimens.
METHODS: A modified Delphi study was conducted among Dutch experts in GC (cyto)pathology. In round 1, sixty-two statements on clinical information, specimen requirements, initial assessment, ancillary testing, biomarker testing and reporting were rated on a 3-point scale (agree/neutral/disagree); consensus was predefined as ≥ 80% agreement. Non-consensus statements were discussed in an online meeting, informed by comments and literature review, revised, and re-rated in Round 2 on a dichotomous agree/disagree scale, with consensus defined as ≥ 70% agreement.
RESULTS: Thirty-one experts from university, general, and independent pathology practices participated. Consensus was achieved for 39 of 62 statements (63%) in Round 1 and for 58 of 62 statements (94%) after Round 2. Consensus was achieved on required clinical information from surgeons, specimen submission and handling, cytological and histological assessment, use of ancillary immunocytochemistry/immunohistochemistry, structured reporting categories, and approaches to biomarker testing on peritoneal biopsies. The study also resulted in structured reporting templates for peritoneal cytology and biopsies.
CONCLUSION: This Delphi study achieved broad expert consensus on pathological assessment of peritoneal fluid and biopsies obtained during staging laparoscopy in GC patients. The resulting recommendations and structured reporting templates provide a practical framework to harmonise specimen handling, evaluation and reporting, thereby promoting greater standardisation and consistency in GC staging.
