AI Article Synopsis

  • * Most patients had advanced T3 tumors with positive lymph node metastases and signs of lymphatic and vascular invasion, indicating a higher risk of recurrence.
  • * Recurrences were diagnosed between 6 to 12 months post-surgery, suggesting that ongoing surveillance for anastomotic recurrence is essential in the months following primary tumor resection.

Article Abstract

Anastomotic recurrence in 6 colorectal cancer cases during the postoperative surveillance between 2008 and 2015 was evaluated retrospectively. Five cases had undergone DST anastomosis for sigmoidectomy and proctectomy. They had a pathological tendency to have T3 tumor and deeper, positive lymph node metastases and positive lymphatic and vascular invasion. There were 2 cases with the anastomotic recurrence diagnosis 6 to 8 months after the primary tumor resection while 4 resected cases had recurrent tumor depth of T3, though 3 cases were diagnosed 1 year after the primary tumor resection. Anastomotic recurrence should be considered a few months after primary tumor resection.
