We are reporting on a case of lymphadenopathy after surgery for rectal cancer. The case was a 66‒year‒old female. Laparoscopic high anterior resection(D3 dissection)was performed for rectal cancer(pT1bpN0M0, pStage Ⅰ)in April 2018, and she was followed up with on an outpatient basis. In July of the same year, a painless mass had formed in the right groin. An abdominal contrast‒enhanced CT showed lymph node swelling around the right groin and external iliac artery, but the tumor markers, CEA 2.3 ng/mL and CA19‒9 <2 U/mL, were within the standard values. An inguinal lymph node biopsy was performed during the same month. Pathological examination revealed no cancer cells and formation of epithelioid granuloma with giant cells. There was no suspicion of systemic sarcoidosis based on the test results and clinical findings. From the above, the patient was diagnosed with sarcoid reaction due to the tumor. Abdominal contrast‒enhanced CT scan 2 months after the biopsy showed lymph node shrinkage and there was no recurrence 2 years after the biopsy.

Several studies explored the application of artificial intelligence (AI) in magnetic resonance imaging (MRI)-based rectal cancer (RC) staging, but a comprehensive evaluation remains lacking. This systematic review aims to review the performance of AI models in MRI-based RC staging. PubMed and Embase were searched from the inception of the database till October 2024 without any language and year restrictions.

Purpose: To investigate the prognostic value of the pretreatment serum carcinoembryonic antigen (CEA) level in patients with rectal cancer treated by preoperative short-course radiotherapy (SCRT) followed by chemotherapy and delayed surgery.
Patients And Methods: Two hundred and sixty-six consecutive patients with locally advanced rectal adenocarcinoma without distant metastasis receiving preoperative radiotherapy were enrolled. Group 1 patients (n=144) received long-course radiotherapy (LCRT) with 50.

Background: Colorectal cancer (CRC) surgeries are commonly performed using either robotic-assisted colorectal surgery (RACS) or laparoscopic colorectal surgery (LCS). This study aimed to compare clinical and surgical outcomes between RACS and LCS for CRC patients.
Methods: We included 225 patients from Tianjin Medical University Cancer Institute & Hospital (TJMUCH) between January 2021 and June 2024, divided into RACS (n=82) and LCS (n=143) groups.

Neoadjuvant chemoradiotherapy (nCRT) is the standard treatment for locally advanced rectal cancer (LARC). Pathological complete regression is closely linked to disease outcomes. However, biomarkers predicting nCRT response and patient survival are lacking for LARC.

Purpose: This study attempted to establish a combined diagnostic model encompassing visualization of the middle rectal artery (MRA) and other imaging features to improve the diagnostic efficiency of lateral lymph node (LLN) metastasis, which is crucial for clinical decision-making in rectal cancer.
Method: One hundred eleven patients receiving bilateral or unilateral lymph node dissection were enrolled, and 140 cases of LLN status on a certain unilateral pelvic sidewall were selected. Enhanced computed tomography (CT) was used to determine whether MRA was visible.
