Objectives
Narrative objectives1 Herein, we examine the relationship between preoperative factors (including imaging findings [CT/MRI], patient factors, and tumor factors) and the presence of pathological lateral lymph nodes metastasis in patients with rectal cancer undergoing rectal resection with lateral pelvic lymph node dissection. From these results, we identify the predicting factors for positive lateral pelvic lymph node metastasis, and determine the criteria of lateral pelvic lymph node positivity in the preoperative diagnosis.

Assessment
Primary outcomes False discovery rate (C/C+D)* regarding the diagnosis of lateral pelvic lymph node metastasis. (*: see below colum)
Key secondary outcomes <1>False omission rate (B/A+B), positive predictive value (D/C+D), negative predictive value (A/A+B), sensitivity (D/B+D), and specificity (A/A+C) regarding the diagnosis of lateral pelvic lymph node metastasis.
<2> False discovery rate (C/C+D), false omission rate (B/A+B), positive predictive value (D/C+D), negative predictive value (A/A+B), sensitivity (D/B+D), and specificity (A/A+C) regarding the diagnosis of lateral pelvic lymph node metastasis when adjusted for one or more patient and tumor factors (including gender, histological tumor type, invasion depth, lymph node metastasis in the mesorectum, and distance from the lower edge of the tumor to the anal verge, which were all determined as factors associated with lateral pelvic lymph node metastasis) and the size of the minor axis of the lateral pelvic lymph node in the imaging studies.
<3> The differences between the central review result and the imaging diagnosis of each institution.

A=preoperatively negative & pathologically negative
B= preoperatively negative & pathologically positive
C= preoperatively positive & pathologically negative
D= preoperatively positive& pathologically positive

Key inclusion criteria 1) Adenocarcinoma or adenosquamous carcinoma is pathologically diagnosed by preoperative biopsy.
2) Pelvic enhanced CT and MRI are performed for preoperative imaging (CT data of 1 mm/1.25 mm-thickness and 5 mm-thickness slices, and MRI data of 3 mm-thickness slices are required).
3) Satisfying either of the following criteria: the main tumor part is located either in the lower rectum or anal canal, or the lower edge of the tumor is located in the lower rectum.
<1> The tumor invasion depth is deeper than T2.
<2> Lateral pelvic lymph node metastasis is suspected by preoperative imaging.
<3> Lymph node metastasis in the mesorectum is suspected by preoperative imaging.
4) Chemotherapy and radiotherapy to the rectal cancer is not performed before the operation, and lateral pelvic lymph node dissection is planned simultaneously with rectal resection.
5) There is no past history of operation, chemotherapy, and radiotherapy to intrapelvic tumors (rectal cancer, gynecologic cancer, urologic cancer, etc.).
6) There is no finding of distant organ metastasis, distant lymph node metastasis, and peritoneal dissemination in the preoperative imaging studies (except for cStage IV).
