The mean age of colorectal cancer in untreated familial adenomatous polyposis (FAP) is 39 years. We present the case of a 21-year-old patient with FAP and colorectal cancer. The patient was detected with significant family history: her mother died at age 45 with colon cancer; two uncles were diagnosed with colon cancer at the age of 40 and 43 and one aunt at the age of 45 with colon cancer and gastric cancer. The treatment was laparoscopic restorative proctocolectomy with total excision of the mesorectum and ileal pouch anal anastomosis completed with endoanal excision of inferior rectal polyps. The histopathological report described a well differentiated rectal adenocarcinoma T1N1aMx developed on a tubulo-villous adenoma located on the rectosigmoid jonction, the rest of the polyps with benign histology.

Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.

Objective: This study aimed to develop a simple machine-learning model incorporating lymph node metastasis status with F-18 Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and clinical information for predicting regional lymph node metastasis in patients with colon cancer.

Methods: This retrospective study included 193 patients diagnosed with colon cancer between January 2014 and December 2017. All patients underwent F-18 FDG PET/CT and blood test before surgery.

Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.
