  • Title: [A Case of Rectal Cancer with Lymph Node Metastasis Diagnosed as Intramucosal Cancer].
    Author: Katada T, Teranishi F, Shibata T, Aoyama Y, Harata S, Shinoda N.
    Journal: Gan To Kagaku Ryoho; 2021 Dec; 48(13):1691-1693. PubMed ID: 35046299.
    Abstract:
    The patient was a 62-year-old man in whom 0-Ⅱa plus Ⅱc lesions in Rs were identified during follow-up observation of multiple colorectal polyps that were found during colonoscopy performed for the examination of fecal occult blood. CT showed no lymphadenopathy or distant metastasis to other organs. Laparoscopic-assisted high anterior resection of the rectum was performed with a diagnosis of clinical stage Ⅰ. Pathologically, there was a well-to-moderately differentiated tubular adenocarcinoma that remained in the lamina propria; however, 1 metastasis was found in the lymph node adjacent to the rectum(#251). Therefore, adjuvant chemotherapy was performed for 6 months after the operation, and 5 years have passed with no recurrence. Here, we report a case with no apparent submucosal invasion but with lymph node metastasis. We confirm recurrence-free survival for 5 years after surgery.
