本文对1984～1988年检出的15例来源于大肠息肉癌变的粘膜下浸润癌(SM癌)进行了5年以上的远期随访观察。15例中,8例行根洽性切除手术,7例在纤维内镜下行息肉切除。随访结果表明:在纤维内镜下切除的7例SM癌,经5年以上的定期随访,无复发。手术切除8例,其中1例死于双肺广泛转移性腺癌,1例局部种植。结果提示:粘膜下浸润癌并非是追加外科手术的绝对指征。 In this paper, 15 cases of submucosal infiltrating carcinoma (SM cancer) from 1984 to 1988 were detected for long-term follow-up observation. Of the 15 patients, 8 underwent radical nephrectomy and 7 underwent polypectomy under fiberoptic endoscopy. Follow-up results showed that: 7 cases of SM cancer underwent endoscopic resection of fiber, after 5 years of regular follow-up, no recurrence. Surgical resection was performed in 8 cases, of which one died of extensive metastatic adenocarcinoma in both lungs and one was locally implanted. The results suggest that submucosal invasive cancer is not an absolute indication for additional surgery.
