Introduction
In the majority of US institutions, gastrectomy specimens are sent for pathologic examination without surgeon assessment or standardized technique of lymph node (LN) assessment for gastric cancer. We conducted a quality improvement project at a US cancer center utilizing surgeon assessment of gastric LNs, and created a video to illustrate a technique of standardized lymph node assessment.
Methods
Convenience sampling was employed among patients with gastric adenocarcinomas who underwent curative-intent D2 gastrectomy between July 2016 and June 2017. For each patient, a surgeon assessed gastric LNs by harvesting individual LNs, followed by conventional evaluation by a pathologist.
Results
We enrolled 17 patients for this quality improvement project. Eight patients underwent total gastrectomy, and nine patients underwent subtotal gastrectomy. Twelve patients underwent preoperative chemoradiation therapy, three underwent preoperative chemotherapy alone, and two underwent upfront surgery. The median number of examined LNs was 43. All patients had ≥ 16 LNs examined, and 88% of patients had ≥ 30 LNs examined.
Conclusion
Surgeon assessment of gastric LN specimens was feasible and effective to provide high-quality pathologic LN assessment after gastrectomy in gastric adenocarcinoma patients. Standardization of the technical methods for gastric LN evaluation is needed to improve the accuracy and quality of gastric cancer staging in the US. The provided video can help inform standardization of gastric LN assessment.
