Detection methods of synchronous colorectal lesions in proximal colon for patients with obstructive colorectal cancer: a literature review

Impact of routine preoperative 18FDG PET/CT on the surgical management of primary colorectal cancer

“…14 Additionally, a complete assessment of the entire large bowel is essential to establish optimal management strategies for patients with CRC due to the high incidence of unexpected synchronous adenomas and adenocarcinomas that have been reported (14%-48% and 2%-9%, respectively). 3,15 Our investigation included 48 (24.6%, 48/195) incomplete colonoscopies. Out of these, 18 FDG-PET/CT detected synchronous colonic lesions in 5 (10.4%, 5/48) patients that were overlooked by both CT and colonoscopy.…”

“…Although representing a major public health issue, colorectal cancer (CRC) is a treatable and often curable disease with a 5‐year survival rate depending on the cancer stage at diagnosis, ranging from 76% to 92% in the initial stages to 10% in those patients with metastatic disease 1 . Approximately 10%–29% of cases present with bowel obstruction at diagnosis 2 and the occurrence of synchronous cancer is estimated to manifest in 0.7%–8.4% of cases 3 …”
