摘要

背景:在胃癌患者的前哨结节导航手术中,前哨结节的术中病理检查对于确定手术范围至关重要。在本研究中,我们利用一项前瞻性多中心随机试验的数据评估了术中病理检查方案的可行性和准确性:我们利用2013年至2016年SE前哨淋巴结ORIented Tailored Approach试验的数据进行了回顾性分析。所有前哨淋巴结均在手术过程中使用苏木精-伊红(HE)染色法进行评估,并在淋巴结最大平面处进行代表性切片。为了进行永久性组织学评估,前哨盆腔淋巴结在福尔马林固定、石蜡包埋(FFPE)切片中采用 HE 和细胞角蛋白免疫组化染色,并以 200μm 的间隔用 HE 检查三个更深一步的切片。对冰冻切片鉴定的失败率和非前哨基地的转移率进行了调查:结果:在 237 例接受前哨结盆地切除术的患者中,30 例经永久病理检查发现有淋巴结转移。13名患者的大转移灶经冰冻切片和FFPE切片证实(失败率:0%)。在冷冻切片中前哨结节为阴性,但在 FFPE 切片中发现微转移的患者在随访期间没有淋巴结复发(0%,0/6)。然而,在冰冻切片中肿瘤阳性结节的病例中,石蜡块中发现了非前哨盆地的转移灶(8.3%,2/24):结论:单切片 HE 染色法足以通过术中病理检查发现大转移灶。结论:单切片 HE 染色法足以通过术中病理检查发现大转移灶,如果冰冻切片结果为阴性,则可以安全地进行前哨盆地切除术。否则,需要进行标准手术。

Feasibility of intraoperative pathologic examination for sentinel lymph nodes during sentinel node navigation surgery in early gastric cancer: results of pathologic protocol for SENORITA trial.

Background: During sentinel node navigation surgery in patients with gastric cancer, intraoperative pathologic examination of sentinel nodes is crucial in determining the extent of surgery. In this study, we evaluated the feasibility and accuracy of intraoperative pathologic protocols using data from a prospective, multicenter, randomized trial.

Methods: A retrospective analysis was conducted using data from the SEntinel Node ORIented Tailored Approach trials from 2013 to 2016. All sentinel lymph nodes were evaluated during surgery with hematoxylin-eosin (HE) staining using a representative section at the largest plane for lymph nodes. For permanent histologic evaluation, sentinel basin nodes were stained with HE and cytokeratin immunohistochemistry in formalin-fixed, paraffin-embedded (FFPE) sections and examined with HE for three deeper-step sections at 200-μm intervals. The failure rate of identification by frozen section and the metastasis rate in non-sentinel basins were investigated.

Results: Of the 237 patients who underwent sentinel node basin dissection, 30 had lymph node metastases on permanent pathology. Thirteen patients had macrometastasis confirmed in frozen sections as well as FFPE sections (failure rate: 0%). Patients with negative sentinel nodes in frozen sections but micrometastasis in FFPE sections had no lymph node recurrence during the follow-up period (0%, 0/6). However, in cases with tumor-positive nodes in frozen sections, metastases in non-sentinel basins were detected in the paraffin blocks (8.3%, 2/24).

Conclusions: The single-section HE staining method is sufficient for detecting macrometastasis via intraoperative pathological examination. If a negative frozen-section result is confirmed, sentinel basin dissection can be performed safely. Otherwise, standard surgery is required.
