摘要
研究直肠癌远侧肠壁浸润的病理学特点。方法:96例直肠癌手术标本,间隔0.5cm,逐层横切肿瘤远侧肠壁,作常规病理学检查。结果:远侧肠壁,有浸润者占69.6％,平均浸润长度为1.34cm,其中隆起型、溃疡型和浸润型分别为1.08cm、1.50cm和3.63cm;高、中分化组和低分化粘液组分别为1.00cm和2.09cm;侵犯周径≤半周径、<全周和全周分别为1.28cm、1.47cm和2.34cm;DukesA、B和C期分别为0.61cm、1.20cm和1.53cm。结论:远侧肠壁浸润长度与大体类型、组织学类型、侵犯周径以及Dukes分期等因素有关。
To study the pathologic patterns of spread along the distal bowel wall in rectal cancer. Methods: In 96 cases of rectal cancer undergoing Miles' procedure, the bowel wall distal to the cancer were sliced transversely every 0.50cm; all specimens were routinely examined by pathology. Results: In 69.6% of the cases, distal spread was found microscopically, the average length of spread was 1.34cm. The length of infiltration along the distal bowel wall was 1.08cm, 1.50cm and 3.63cm respectively when the tumor belonged to the protuberant, ulcerative or infiltrating type. The distal spread measured 1.00 cm in highly or moderately differentiated carcinoma, and 2.09cm in poorly differentiated or mucoid car-cinoma. The length of distal spread was 1.28cm, 1.47cm and 2.34cm respectively when the tumor invol-ved larger or less than half the circumference, or infiltrated the whole circumference. The extent of dis-tal spread was 0.61cm, 1.20cm and 1.53cm respectively in Dukes A, B or C cases. Conclusions: The length of distal spread was correlated to the gross morphology, histologic type, the extent of the tumor and its Dukes' staging.
