BackgroundTo compare clinicopathologic feature of rectal neuroendocrine tumor (NET) grade G1 with G2 NET.MethodsSix hundred-one cases of rectal G1 and G2 NETs diagnosed in our center were analyzed.ResultsOf 601 cases of rectal NET, 515 cases were with grade G1 and 86 cases were with grade G2. Median tumor size was 0.7 cm. Compared with G1 NET, G2 tumors were with significantly larger tumor size (0.8 vs 2.2 cm, p < 0.001), less percentages of patients with tumors confined to submucosa (92.6 vs 42.8%, p < 0.001), more frequent presence of microvascular invasion (MVI) (3.6 vs 16.9%, p < 0.001) or peri-neural invasion (PNI) (2.0 vs 24.1%, p < 0.001). Incidence of lymph node and distant metastasis was 5.2 and 2.1% in G1 NET compared with 44.2 and 31.4% in G2 tumor, respectively (p < 0.001). For tumors sized 1–2 cm and confined to submucosa, incidence of lymph node metastasis was 6.1% for G1 NET compared with 21.1% for G2 NET. Status of MVI/PNI was predictive of lymph node metastasis for G2 tumor rather than G1 NET in this subgroup.ConclusionsRectal G2 NET was much more invasive with significantly elevated prevalence of lymph node metastasis compared with G1 tumor.

Tumors of the small intestine are rare. In addition, clinical symptoms are nonspecific and neoplasm-related symptoms occur late. We report a case of neuroendocrine tumor (NET) of the small intestine that was diagnosed early with trans-abdominal ultrasonography (US). The patient was a 61-year-old man. Abdominal contrast-enhanced computed tomography (CT) was performed because the patient complained of abdominal pain. The CT showed a tumor lesion in the mesentery. Trans-abdominal US was undertaken to evaluate this tumor lesion, and a tumor lesion of the small intestine was found nearby. A diagnosis of lymph-node metastasis of a small-intestine tumor was made as a preoperative diagnosis. A laparotomy was performed with partial resection of the ileum, together with the small-intestine mesentery including an enlarged lymph node. Histological examination revealed NET of the ileum and lymph-node metastasis. Trans-abdominal US is useful in the diagnosis of small-intestine NET.
