摘要
目的探讨胰头癌淋巴结微转移的发生规律,分析其对胰头癌患者预后的影响。方法以手术显微镜法完整取出40例行胰腺癌根治术及区域淋巴结清扫的胰头癌患者的淋巴结,采用细胞角蛋白单克隆抗体(AEl/E3),以免疫组化法复检常规病理检查结果为阴性的淋巴结,统计各组淋巴结临床转移和微转移的发生率,分析淋巴结微转移与胰头癌患者预后的关系。结果40例患者共收集1550枚淋巴结。常规病理检查结果显示,27例患者的199枚淋巴结存在临床转移,患者的淋巴结阳性率为67.5%(27/40),淋巴结转移率为12.8%(199/1550)。以免疫组化法对1301枚阴性淋巴结进行复检,检出6例患者共130枚淋巴结存在微转移。综合常规病理检查和免疫组化检查结果,40例患者的淋巴结阳性率为82.5%(33/40),与单纯常规病理检查比较,差异无统计学意义(P=0.121);淋巴结转移率为21.2%(329/1550),与单纯常规病理检查比较,差异有统计学意义(P〈0.001)。常规病理检查结果显示,淋巴结转移率较高的为第13组(24.1%,68/282)、第14组(18.1%,58/321)、第12组(12.7%,31/245)、第16组(12.3%,30/243)和第17组(11.4%,12/105)。免疫组化检查结果显示,微转移发生率较高的淋巴结分别为第14组(16.5%,53/321)、第13组(15.2%,43/282)、第16组(6.2%,15/243)、第12组(4.9%,12/245)和第8组(5.O%,7/141)。综合两种检查结果,淋巴结转移率较高的组别分别为第13组(39.4%,111/282)、第14组(34.6%,111/321)、第16组(18.5%,45/243)、第12组(17.6%,43/245)和第17组(11.4%,12/105)。11例患者生存超过1年,29例患者在术后8~11个月内死于复发或转移,40例患者的1年生存率为27.5%。其中,常规病理检测淋巴结阳性患者的1年生存率为14.9%,常规病理检测淋巴结阴性、免疫组化检测淋巴结阳性患者的1年生存率为33-3%,二者差异无统计学意义(P=0.632);常规病理检测与免疫组化检测均阴性患者的1年生存率为71.4%,与常规病理检测阳性组患者的1年生存率比较,差异有统计学意义(P=0.010)。结论联合应用常规病理检查和免疫组化检查可有效提高胰头癌淋巴结微转移的检出率,第13、14、12、16和8组淋巴结易发生微转移,存在微转移的患者预后明显较差。在行胰腺癌根治性切除术时,应特别注意对第13、14、16、12和17组等转移率较高的淋巴结进行清扫。
Objective To investigate the occurrence of lymph node micrometastasis in pancreatic head carcinoma and analyze its effect on the prognosis of patients. Methods The lymph nodes in 40 patients who received pancreatoduodenectomy with regional lymphadencctomy were dissected by surgical magnification microscopy. The expression of cytokeration(AE1/E3) were detected by immunohistochemical staining in the pathologically negative lymph nodes. The frequency of lymph nodes metastases and micrometastases, as well as the relationship between metastasis and prognosis were analyzed. Results 1 550 lymph nodes were dissected from 40 patients. Lymph node metastases was pathologically detected in 27 patients (67.5%) and in 199 lymph nodes(12.8%). No.13(24.1% ,68/282), No. 14( 18.1% ,58/321 ), No, 12( 12.7%,31/245), No. 16 ( 12.3%, 30/243 ) and No. 17 ( 11.4%, 12/105 ) lymph nodes groups had higher frequency of metastases. Lymph node micrometastases was immunohistochemically detected in 6 patients and 130 lymph nodes. No.14( 16.5% ,53/321), No.13( 15.2% ,43/282), No.16( 6.2%, 15/243), No.12(4.9%, 12/245) and No.8(5.0%,7/141 ) lymph nodes groups had higher frequency of micrometastases. The total ratio of patients with postive lymph nodes invasion and the ratio of positive lymph nodes invasion were 82.5% and 21.2%. 11 patients survived more than one year. 29 patients died of recurrence or metastasis within 8- 11 months after surgery. The 1-year survival rate was 27.5%. 1-year survival rate was 14.9% in HE (+) patients, and 33.3% in HE (-) AE1/E3 (+) patients (P=0.632). AE1/E3 (-) HE (-) patients had a 1-years survival rate of 71.4%, which was statistically higher than that in HE (+) group patients (P= 0.010). Conclusions AE1/E3 combined with pathological examination can significantly improve the detection rate of lymph nodes micrometastasis in pancreatic head carcinoma patients. Micrometastasis is commonly found in No 13, 14, 12, 16, 8 lymph nodes groups. Lymph nodes micrometastasis had a significant effect on the prognosis of patients. Special attention should be payed to No 13, 14, 16, 12, 17 lymph nodes groups during radical duodenopancreatectomy.
