“…It is difficult to identify certain small tumors on CT, and sometimes complete examination of the large intestine cannot be conducted, due to intestinal lumen stenosis. The combined use of CT and colonoscopy has been reported as a useful tool for the preoperative evaluation of synchronous colorectal carcinoma (15,16). Colonoscopic examination may provide clear images of the whole colon.…”

Abstract. Synchronous colorectal cancers refer to the simultaneous occurrence of multiple colorectal tumors in a single patient, excluding any metastases from other organs. At present, radical surgery is considered the standard curative treatment; however, individualized surgical strategies depend on tumor location, the depth of invasion and the general health of the patient. In the present study, the case of a 52-year-old man who presented with a 2-month history of abdominal pain that was accompanied by intermittent hematochezia and weight loss is reported. The patient had no family history of cancer. Computed tomography (CT) of the abdomen revealed intestinal wall thickness in the transverse colon and volvulus in the hepatic flexure of colon. Colonoscopy identified 3 tumors: The first tumor was located in the descending colon with lumen stenosis ~60 cm from the anal verge, the second tumor was located in the hepatic flexure of the colon, and the third tumor was located in the sigmoid colon, 23 cm from the anal verge. Subsequently, laparoscopic subtotal colectomy was performed and all three tumors were removed, and the diagnosis was confirmed by histopathological examination. The patient did not undergo chemotherapy following surgery, due to personal reasons. Subsequent to 19 months of follow-up examinations using CT and colonoscopy every 6 months, the patient exhibited no signs of recurrence. Thus, laparoscopic subtotal colectomy represents an effective surgical approach for the treatment of synchronous colorectal cancer following imaging and endoscopic diagnosis.

“…CT colonography is above all of value in those patients with stenosis or colon elongation that leads to incomplete colonoscopy. It is not only useful in the evaluation of the proximal bowel, but can also provide surgeons with accurate information about staging and tumor localization [35,36]. Other technical advances, such as magnetic resonance colonography [37] and the combination of CT colonography with PET [38], have been reported as useful tools for the preoperative evaluation of SCRCs.…”

Synchronous Colorectal Cancers: A Review of Clinical Features, Diagnosis, Treatment, and Prognosis

Background/Aims: With the development of early diagnostic technologies, more synchronous colorectal cancers (SCRCs) can be clinically detected. Although SCRCs are recognized as a significant clinical entity, their clinical features, diagnosis, treatment, and prognosis have yet to be definitively established. In order to obtain a comprehensive understanding of this disease and to establish an efficient profile by which to recognize individuals at high risk of developing SCRCs, we carried out a review of the relevant literature. Methods: The PubMed database was searched for publications of ‘synchronous colorectal carcinoma/cancer/adenocarcinoma’ and ‘multiple colorectal carcinomas’. All publications up to January 2011 were considered, and then only articles in English were retrieved for inclusion in this review. Results: The incidence of SCRCs was found to be higher in older and male patients. The prognosis in patients with SCRCs was equivalent to that in patients with solitary CRC. The failure to diagnose synchronous lesions before and during the operation was associated with repeated surgery. Conclusion: SCRCs possess distinctive features compared to solitary CRC. While all colorectal patients should be carefully assessed to rule out the presence of concurrent colon adenomas, since missed lesions can result in additional surgery and poor prognosis, particular attention should be given to the high-risk group of older male patients.

“…CTC studies referred for (a) staging and/or synchronous lesion detection (these have been previously reported from our unit [21]) and (b) those undertaken as part of follow-up for previous colorectal resection were excluded. For each CTC study the following data were collected; patient demographics (age, sex, date of birth and referring clinician/specialty); CTC details (year of CTC, date of request, study date, principle indication/patient symptoms (In patients with more than one indication/symptoms, the prime or leading symptom was recorded); CTC findings and reporting radiologist; endoscopic investigation (pre-or post-CTC, date and findings) and follow-up clinical information (letters from outpatients department, any further radiological or endoscopic investigation were collected from the hospital electronic patient archive system).…”
