Endoscopically, rectal carcinoids have a variety of sizes and features which may assist in determining treatment plans. The present study was performed to assess the relationship between endoscopic features and metastasis in rectal carcinoids.
A total of 115 rectal carcinoids of 112 patients with rectal carcinoids were enrolled, and the medical records were retrospectively reviewed. All tumors were classified according to size (longest diameter), and then according to endoscopic features such as shape, color, and surface changes including depressions, erosion, and ulceration. The relationship between endoscopic features and metastasis was evaluated.
11 cases (9.6%) of the 115 rectal carcinoids presented with metastatic disease. Tumor size was associated with metastasis (p < 0.001). Endoscopic features associated with metastasis were tumor shape, surface change, and color (p < 0.001). Atypical endoscopic features occurred more frequently as the size of the tumor increased (p < 0.001). For tumors 10-19 mm in diameter, atypical surface change was associated with metastasis (p = 0.007).
Endoscopic features were found to be associated with metastasis in rectal carcinoids. In particular, atypical surface change may be useful in determining treatment plans for tumors 10-19 mm in diameter.
在结肠镜检查中，直肠类癌有多种大小和特征，这可能有助于确定治疗方案。本研究旨在评估直肠类癌的内镜特征与转移之间的关系。
共纳入112例直肠类癌患者的115个直肠类癌，并对病历进行回顾性分析。所有肿瘤均根据大小（最长直径）进行分类，然后根据内镜特征如形状、颜色以及包括凹陷、糜烂和溃疡在内的表面变化进行分类。评估内镜特征与转移之间的关系。
115个直肠类癌中有11例（9.6%）出现转移。肿瘤大小与转移相关（p < 0.001）。与转移相关的内镜特征为肿瘤形状、表面变化和颜色（p < 0.001）。随着肿瘤大小增加，非典型内镜特征出现的频率更高（p < 0.001）。对于直径为10 - 19 mm的肿瘤，非典型表面变化与转移相关（p = 0.007）。
发现直肠类癌的内镜特征与转移相关。特别是，非典型表面变化可能有助于确定直径为10 - 19 mm肿瘤的治疗方案。
