Studies have suggested that perineural invasion (PNI) and lymphovascular invasion (LVI) serve as independent prognostic factors in colorectal cancer (CRC). Currently, little is known regarding the combination of PNI and LVI as prognostic factors, independent of stage. We hypothesized that this combination was a better prognostic marker than either PNI or LVI alone, and that S100 staining would detect PNI not seen with hematoxylin and eosin (H&E). Surgical pathology slides were retrospectively reviewed for 151 stages I to IV CRC patients who had surgery between January 1, 2008 and December 8, 2008 at 3 Hackensack Meridian Health hospitals in New Jersey. PNI and LVI were detected by H&E staining and a subset of 127 patient samples were additionally examined for PNI by S100 staining. Correlation between staining characteristics and patient outcomes was assessed using the Pearson χ2 tests and the Fisher exact tests. Survival was analyzed using Kaplan-Meier methods. Of the 151 cases reviewed, 30.5% were positive for PNI and 35.1% were positive for LVI by H&E. The use of S100 staining for PNI enabled its detection in 27 additional cases. Median time from patient diagnosis to death was significantly shorter for patients who were positive for both PNI and LVI (P<0.001). PNI and LVI were individual markers for poor survival in CRC patients and their combined presence had an even worse outcome. Failure to detect PNI on H&E can be overcome by S100 staining.

S100染色增加了结直肠癌周围神经浸润和淋巴血管浸润联合的预后意义

研究表明,神经周围浸润 (PNI) 和淋巴血管浸润 (LVI) 是结直肠癌 (CRC) 的独立预后因素。目前,关于 PNI 和 LVI 的组合作为独立于分期的预后因素知之甚少。我们假设这种组合是比单独的 PNI 或 LVI 更好的预后标志物,并且 S100 染色将检测到苏木精和伊红 (H&E) 未见的 PNI。对 2008 年 1 月 1 日至 2008 年 12 月 8 日在新泽西州 3 家 Hackensack Meridian Health 医院接受手术的 151 名 I 至 IV 期 CRC 患者的手术病理切片进行了回顾性审查。通过 H&E 染色检测 PNI 和 LVI,并通过 S100 染色额外检查了 127 个患者样本的子集的 PNI。使用 Pearson χ2 检验和 Fisher 精确检验评估染色特征和患者结果之间的相关性。使用 Kaplan-Meier 方法分析存活率。在审查的 151 例病例中,30.5% 的 PNI 呈阳性,35.1% 的 H&E 呈 LVI 阳性。使用 S100 染色进行 PNI 使其能够在另外 27 例中检测到。对于 PNI 和 LVI 均为阳性的患者,从患者诊断到死亡的中位时间显着缩短(P<0.001)。PNI 和 LVI 是 CRC 患者生存不良的个体标志物,它们的联合存在会导致更糟的结果。S100 染色可以克服在 H&E 上检测不到 PNI 的问题。5% 的 PNI 呈阳性,35.1% 的 H&E 呈 LVI 阳性。使用 S100 染色进行 PNI 使其能够在另外 27 例中检测到。对于 PNI 和 LVI 均为阳性的患者,从患者诊断到死亡的中位时间显着缩短(P<0.001)。PNI 和 LVI 是 CRC 患者生存不良的个体标志物,它们的联合存在会导致更糟的结果。S100 染色可以克服在 H&E 上检测不到 PNI 的问题。5% 的 PNI 呈阳性,35.1% 的 H&E 呈 LVI 阳性。使用 S100 染色进行 PNI 使其能够在另外 27 例中检测到。对于 PNI 和 LVI 均为阳性的患者,从患者诊断到死亡的中位时间显着缩短(P<0.001)。PNI 和 LVI 是 CRC 患者生存不良的个体标志物,它们的联合存在会导致更糟的结果。S100 染色可以克服在 H&E 上检测不到 PNI 的问题。PNI 和 LVI 是 CRC 患者生存不良的个体标志物,它们的联合存在会导致更糟的结果。S100 染色可以克服在 H&E 上检测不到 PNI 的问题。PNI 和 LVI 是 CRC 患者生存不良的个体标志物,它们的联合存在会导致更糟的结果。S100 染色可以克服在 H&E 上检测不到 PNI 的问题。
