“…Therefore, stenting does not always make preoperative TCS possible. In contrast, CT colonography can be used to detect synchronous proximal colon cancers in patients with obstructive lesions ( 16 ), although the procedure requires adequate bowel preparation, fecal tagging, and colonic distension using air or CO 2 . Nevertheless, PET/CT can detect colonic lesions even if the colon proximal to the obstruction is not adequately prepared ( 17 ).…”

Positron emission tomography/computed tomography (PET/CT) is frequently used to detect colorectal cancer. The present retrospective study assessed the ability of PET/CT to identify synchronous colonic lesions in 72 patients with obstructive colorectal cancer. All patients had undergone surgical resection without undergoing preoperative total colonoscopy (TCS) at the Digestive Disease Center (April 2007 to September 2016), and subsequently underwent TCS of the proximal colon within 2 years post-surgery. A total of 11 patients exhibited 18F-fluorodeoxyglucose uptake during PET/CT of the proximal colon (4 invasive cancers, 3 advanced adenomas and 4 false-positive results), and 61 patients had no uptake in the proximal colon. Among these 61 patients, postoperative TCS revealed 2 invasive cancers and 4 advanced adenomas. The sensitivity of PET/CT for detecting synchronous invasive cancers was 66.6% (4/6), with a specificity of 89.4% (59/66), a positive predictive value of 36.4% (4/11), a negative predictive value of 96.7% (59/61), and an accuracy of 87.5% (63/72). Negative PET/CT results indicated a low probability of synchronous lesions in the proximal colon. Thus, PET/CT may be a useful tool for detecting synchronous colonic cancers in patients with obstructive colon cancer.

“…Preoperative CTC is an accepted indication after an optical colonoscopy that was incomplete because of an obstructing tumor. CTC results in accurate identification and localization of an obstructing tumor, reliably detects synchronous tumors, and allows improved visualization of the colon proximal to the obstruction compared with DCBE or intraoperative palpation [117][118][119][120] . In addition, CTC is well tolerated and less invasive than contrast enema in these cases.…”

Increased screening by CTC is expected to result in a decrease in the incidence of and mortality due to CRC. Increased preoperative staging and navigation surgery by use of CTC is expected to secure an accurate choice of the precise therapeutic plan and a safer performance of surgery. Together, a comprehensive program for screening, preoperative staging, and navigation surgery based on CTC will ultimately reduce the mortality due to CRC.

Synchronous triple carcinoma of the colon and rectum

Synchronous multiple colorectal cancers are defined as multiple malignant colorectal tumors that occur simultaneously. All tumors are distant from each other, and none are the result of metastasis from other tumors. Here, we present a case of a 79-year-old man who was admitted to our hospital because of a 3-month history of abdominal pain associated with anemia, loss of appetite, and body weight loss. The patient did not have a family history of cancer. Computed tomography revealed bowel wall thickness and mesentery inflammation at the hepatic flexure of the colon and cecum. Colonoscopy revealed a tumor located 10 cm from the anal verge. Colonoscopic examination of the large bowel was not possible because of bowel obstruction due to the rectal tumor. Synchronous triple adenocarcinoma of the colon and rectum was confirmed by pathologic examination. The tumor was surgically resected by two-segment resection of the colon, low anterior resection, and right hemicolectomy. We used intraoperative colonoscopy to confirm that there were no other lesions after the resection of the three tumors. To the best of our knowledge, this is the first case of synchronous triple carcinoma of the colon and rectum in Taiwan. We consider that comprehensive preoperative study, extensive intraoperative exploration, and radical resection can increase the survival rate of patients with synchronous multiple colorectal cancers.
