Abstract

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.

从手术室到病理报告:腹腔镜胃癌分期腹膜细胞学和活检病理评估的德尔菲共识。
背景:在选定的胃癌(GC)患者中,建议采用腹腔镜腹膜细胞学和活检进行分期,但缺乏评估腹膜灌洗/腹水和腹膜活检的实用指南。我们旨在就这些标本的处理、评估和报告制定基于共识的建议。方法:对荷兰GC(细胞)病理学专家进行了改进的德尔菲研究。在第1轮中,62份关于临床信息、标本要求、初步评估、辅助测试、生物标志物测试和报告的陈述以3分制进行评分(同意/中性/不同意);一致性定义为≥80%的一致性。在在线会议上讨论非共识陈述,通过评论和文献综述告知,修改,并在第二轮中以同意/不同意的二分量表重新评分,共识定义为≥70%同意。结果:31名来自高校、全科和独立病理实践的专家参与了研究。在第一轮中,62个声明中有39个(63%)达成了共识,在第二轮之后,62个声明中有58个(94%)达成了共识。在外科医生的临床信息、标本提交和处理、细胞学和组织学评估、辅助免疫细胞化学/免疫组织化学的使用、结构化报告类别和腹膜活检生物标志物检测方法等方面达成了共识。该研究还产生了腹膜细胞学和活检的结构化报告模板。结论:本德尔菲研究在胃癌患者腹腔镜分期时对腹膜液和活检的病理评估方面取得了广泛的专家共识。由此产生的建议和结构化报告模板提供了一个实用的框架,以协调标本处理、评估和报告,从而促进气相色谱分级的更大标准化和一致性。
