Abstract Purpose The aim of this study is to investigate the clinical significance of lateral lymph node metastasis with no mesenteric lymph node metastasis after lateral lymph node dissection in middle and low rectal cancer .Methods Retrospective analysis was performed on the clinical data of 5 consecutive patients who were pathologically diagnosed with lateral lymph node metastasis, while mesenteric lymph node metastasis was not observed after laparoscopic lateral lymph node dissection underwent for advanced low rectal cancer from July 2017 to August 2019.Results All the 5 patients were successfully completed laparoscopic lateral lymph node dissection, and no cases were transferred to laparotomy.The mean age was 58.80±6.53 years, Two Miles surgeries and three Dixson surgeries were performed.Conclusion We found that some patients had lateral lymph node metastasis, while mesenteric lymph nodes had no metastasis after lateral lymph node dissection.This phenomenon suggests that lateral lymph nodes are one of the important metastasis pathways of low rectal cancer,a new N stage is needed to distinguish it from other types of lymph node metastasis.In addition, LLND is of great significance for the pathological diagnosis of lateral lymph nodes.

Abstract Background The effectiveness of prophylactic lateral lymph node dissection (LLND) in treating patients with lower rectal cancer remains controversial and has not been clearly established. Therefore, we aimed to retrospectively analyze the survival impact of prophylactic LLND in patients with lower rectal cancer. Methods Data of 301 patients with lower rectal cancer (tumor’s lower edge on the anal side of the peritoneal reflexion) with clinical T3 disease and negative preoperative lateral lymph node metastasis, who underwent radical resection (R0) at our hospital between April 2007 and March 2017, were included in this study. Patients who received preoperative chemotherapy or radiotherapy were excluded. The relapse-free survival (RFS) and overall survival (OS) rates were compared between the dissection (prophylactic LLND, n = 37) and non-dissection (no prophylactic LLND, n = 264) groups. Results Significantly fewer men and younger patients were noted in the dissection group than in the non-dissection group. Post-surgery 3- and 5-year RFS rates were 69.6% and 66.8% in the dissection group and 75.1% and 72.5% in the non-dissection group, respectively (5-year post-surgery RFS, p = 0.58). In the dissection and non-dissection groups, the 5-year OS rates were 86.5% and 79.7%, respectively (p = 0.29), and the 5-year cancer-specific survival rates were 88.9% and 86.0%, respectively (p = 0.29), with no significant differences. Lateral lymph node recurrence was observed in one (2.7%) and 10 patients (3.8%) in the dissection and non-dissection groups, respectively, and there was no significant difference between the groups. Conclusions In this study, the effectiveness of prophylactic LLND was limited in patients with > T3 lower rectal cancer with no evidence of preoperative lymph node metastasis. Prophylactic LLND may not be necessary if there is no preoperative lymph node metastasis, even if the invasion depth is T3 or higher.

Abstract Introduction: There are controversies over the treatment options for pelvic lymph node metastasis in low rectal cancer. The role of neoadjuvant radiotherapy in radical treatment of pelvic lymph node metastasis is still unidentified. Total mesorectal excision (TME) with Laparoscopic pelvic lymph node dissection (LPLND) provides lower pelvic recurrence in 5 years than TME only. Material and Methods: Prospective, uncontrolled clinical trial for patients with low rectal cancer (below peritoneal fold), who had suspected lateral pelvic lymph node metastasis on MRI scan and the patients did not have contraindication for laparoscopic surgery. Result: From January 2017 to February 2018 we performed 12 cases of LPLND. There was no con-version to open surgery. The average time for lymphadenectomy is 75 minutes with an average amount of blood loss of 97ml. Only 1 case had postoperative urinary retention (8%). The rate of pos-itive pelvic node was 5.8%, with an average of resected nodes of 4.9 nodes. Lymph nodes size on MRI scan in the positive pelvic node group was 20.6mm, compared to 7mm in the negative group. Conclusion: Laparoscopic lateral pelvic lymph node dissection is a feasible and safe technique and should be done by experienced colorectal surgeons. Aging, female sex and pelvic lymph node size on MRI are related to pelvic lymph node metastasis.
