Abstract
BACKGROUND

There are a few cases of lateral lymph node (LLN) metastasis (LLNM) of T1 rectal cancer. Moreover, LLNM is easily missed, especially in patients with early-stage rectal cancer. To our knowledge, the possibility of bilateral LLNM before surgery has not been reported in previous studies.

CASE SUMMARY

A 36-year-old woman underwent endoscopic submucosal dissection at a local hospital owing to a clinical diagnosis of a rectal polyp. The pathology report showed a diagnosis of T1 rectal mucinous adenocarcinoma. She was considered to have bilateral LLNM after the examination at our hospital. Laparoscopic total mesorectal excision plus bilateral LLN dissection was performed and the pathological outcomes indicated unilateral LLNM. The patient received long-course adjuvant chemoradiotherapy with no recurrence or metastasis observed during the 1-year follow-up period.

CONCLUSION

T1 rectal cancer could lead to LLNM and possibly, bilateral LLNM. Therefore, adequate clinical evaluation is essential for these patients.

Core Tip: T1 rectal cancer is rarely accompanied by lymph node metastases, and even fewer lateral lymph node (LLN) metastases (LLNM). To our knowledge, the published case reports to date have mainly reported cases of heterochronous LLNM, only two cases with simultaneous metastases, and only one case of missed LLNM after endoscopic submucosal dissection (ESD). For patients with no residual tumor after ESD, in whom LLNM is suspected, it is also inconclusive whether only LLN dissection could be performed.
