研究目的:

主要目的: 前瞻性评估S100免疫组化联合HE染色相较于单纯HE染色在I-III期结肠癌术后病理神经侵犯(PNI)检出率中的差异,以验证联合检测能否显著提高PNI诊断敏感性。 次要目的: (1)S100+HE PNI(+)与患者预后的关系; (2)临床影响评估:分析PNI检出率提高对术后辅助治疗决策(如化疗方案调整)的影响。 (3)探索PNI阳性率与T/N分期、脉管浸润、肿瘤分化程度等其他高危病理因素的相关性。 (4)病理诊断标准化:评估联合染色在不同年资病理医师间的诊断一致性(Kappa值)。  

Objectives of Study:

Primary Objective:To prospectively evaluate the difference in the detection rate of perineural invasion (PNI) in postoperative pathological specimens of stage I–III colon cancer between S100 immunohistochemistry combined with HE staining and HE staining alone, and to verify whether the combined detection can significantly improve the diagnostic sensitivity of PNI.Secondary Objectives:To investigate the relationship between S100+HE staining-detected PNI (+) and patient prognosis.To assess the clinical impact: analyze the influence of an improved PNI detection rate on decision-making for postoperative adjuvant therapy (e.g., adjustment of chemotherapy regimens).To explore the correlation between PNI positive rate and other high-risk pathological factors, including T/N stage, lymphovascular invasion, and tumor differentiation grade.To standardize pathological diagnosis: evaluate the diagnostic agreement (Kappa value) of combined staining among pathologists with different seniority.
