摘要
目的探讨直肠癌根治术中各临床病理特征、手术方式等相关因素对肠腔内肿瘤细胞脱落的影响。方法对我科2006年5月至2007年12月期间诊断为直肠癌并行根治手术的60例患者行前瞻性研究,术中在离断肿瘤下端肠管前行肠腔内灌洗,收集灌洗液送病理科,用普通涂片、HE染色检测送检标本中的癌细胞。统计检测结果,应用包括Logistic回归分析等统计学方法分析各因素对术中肠腔肿瘤细胞脱落的影响。结果送检标本中,阳性标本共有27例,阴性标本33例。对可能影响检出结果的各因素行单因素统计分析,结果患者的年龄、肿瘤大小、TNM分期、手术时间及手术方式这5个因素的差异有统计学意义(P<0.05)。进一步将这5个因素行Logistic多因素回归分析,发现TNM分期、手术时间及手术方式是影响肠腔内肿瘤细胞脱落的决定因素,其中TNM分期影响最显著,手术时间的影响次之,最后是手术方式。结论直肠癌根治术中必须常规行肠腔内灌洗,特别是肿瘤TNM分期晚、瘤体大及手术时间长的病例,更需重视肿瘤细胞脱落导致术后局部复发的风险。虽然腹腔镜直肠癌手术中直肠肠腔内肿瘤细胞脱落的几率较传统开腹手术明显要小,但仍有必要进行有效灌洗。
Objective To analyze the risk factors inducing tumor cells exfoliating during radical resection of rectal cancer. Methods Sixty patients who were diagnosed as rectal cancer from May 2006 to November 2007 and given radical operations were assigned prospectively in this study. Before cutting the rectal stump below the tumor, saline was instilled into rectum to irrigate the stump. Collected irrigating fluids were sent to pathology laboratory, and the exfoliated malignant cells were tested by HE （haematoxylin and eosin） dyeing and common smear technique. The results of examines were collected and statistical analysis, including a Logistic regression model, was performed. Results Exfoliated malignant ceils were found in 27 samples. By univariate analysis, the statistically significant factors defining a high risk of exfoliating were age, tumor size, TNM stage, operation time and operation method （P〈0.05）. Only TNM stage, operation time and operation method were confirmed by Logistic regression analysis to independently result in a statistically significant increased risk of exfoliating. Conclusion Irrigating the rectal stump before cutting down the tumor is essential to avoid local recurrence. The effects of TNM stage, tumor size and operation time are important. Although the laparoscopic surgery is more predominant than conventional surgery for non-neoplasma technology, irrigating is an important process.
