Abstract
PURPOSE To assess the impact of surgical approach on morbidity, mortality, and the oncological outcomes of synchronous (SC) and metachronous (MC) colorectal cancer (CRC). METHODS All patients undergoing resection for double location CRC (SC or MC) between 2006 and 2020 were included. The exclusion criteria were polyposis or SC located on the same side. RESULTS Sixty-seven patients (age, 64.8 years; male, 78%) with SC (n = 41; 61%) or MC (n = 26; 39%) were included. SC was treated with segmental colectomy (right and left colectomy/proctectomy; n = 19) or extensive colectomy (subtotal/total colectomy or restorative proctocolectomy with pouch; n = 22). Segmental colectomy was associated with a higher incidence of anastomotic leakage (47.4 vs. 13.6%; p = 0.04) and a higher rate of medical morbidity (47.4 vs. 16.6%; p = 0.04). The mean number of lymph nodes harvested was similar. For MC, the second cancer was treated by iterative colectomy (n = 12) or extensive colectomy (n = 14) and there was no significant difference in postoperative outcomes between the two surgical approaches. The median follow-up period was 42.4 ± 29.1 months. The 5-year overall and disease-free survival of the SC and MC groups did not differ to a statistically significant extent. CONCLUSIONS Extensive colectomy should be preferred for SC to reduce morbidity and improve the prognosis. In contrast, iterative colectomy can be performed safely for patients with MC.

Abstract
INTRODUCTION Colorectal cancer holds a high morbidity and mortality rate. As a common method for colorectal cancer detection, colonoscopy has difficulty in passing through the malignant stenosis in patients with obstructive colorectal cancer, which results in incomplete detection and missed diagnosis. The missed synchronous lesions increase the risk of metachronous cancer. Therefore, detecting proximal synchronous lesions in patients with obstructive colorectal cancer should be appreciated before operation. AREA COVERED This review evaluates related literature, aiming at providing clinicians with more ideas and attention for detecting proximal synchronous lesions in patients with obstructive colorectal cancer. EXPERT OPINION In patients with obstructive colorectal cancer, missed diagnosis of lesions proximal to the obstruction may lead to metachronous colorectal cancer. Except for preoperative colonoscopy which is difficult to pass through malignant stenosis, other methods that can evaluate proximal colon segment are critical. This article introduced several preoperative, intraoperative and postoperative measures for synchronous lesions detection. The choice of methods should base on patients' conditions, aiming at a high diagnostic yield and low risk. Early detection and resection of synchronous lesions in the proximal section of malignant obstruction are expected to minimize the risk of metachronous colorectal cancer and even effect follow-up treatment strategy, which deserves the attention of clinicians.

Ultrathin colonoscopy can improve complete preoperative colonoscopy for stenotic colorectal cancer: Prospective observational study. Dig Endosc 2021; 33:621-628. [PMID: 32867005 DOI: 10.1111/den.13829] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 08/18/2020] [Accepted: 08/21/2020] [Indexed: 01/15/2023]
Abstract
OBJECTIVES Preoperative colonoscopy is often incomplete for stenotic colorectal cancers (CRC). This prospective observational study aimed to evaluate the ability of an ultrathin colonoscope (UTC) to inspect the whole colon by passing through the stenotic CRC. METHODS All patients who underwent preoperative colonoscopy for stenotic CRCs at Shizuoka Cancer Center were examined for eligibility. If a standard colonoscope (PCF-H290ZI) could not pass because of a stenosis, the patients were recruited. All of the eligible patients were prospectively enrolled when informed consent could be obtained, and complete colonoscopy was attempted again using an UTC (PCF-PQ260L). Patients with stent placement and those requiring right hemicolectomy were not recruited. Primary endpoints were pass-through and cecal intubation rates. The detected synchronous neoplasias (adenomas and cancers) and their pathological findings after resection were evaluated. RESULTS A total of 100 patients were enrolled between September 2017 and February 2019. The mean age was 65.6 ± 10.8 years, and 59% were male. The pass-through and cecal intubation rates were 67% (67/100) and 58% (58/100), respectively. Synchronous lesions located proximal to the stenoses were detected in 65.5% (38/58) of the complete colonoscopies, with a total of 86 lesions, including 18 advanced neoplasias with three invasive cancers. CONCLUSION When standard colonoscopy cannot pass through stenotic CRC, ultrathin colonoscopy can be considered as an option to inspect the whole colon proximal to the stenosis because treatment strategy can potentially be changed by detecting synchronous neoplasias proximal to the stenosis before surgery.

Abstract
Introduction patients with sporadic colorectal cancer or cases associated with syndromes are at risk of having synchronous or metachronous cancer. Although it is an important subject, Brazilian data on the subject are scarce.
Objective to evaluate the incidence and epidemiological features in patients with synchronous and metachronous colorectal cancer in a reference service of proctology in the Rio Grande do Sul.
Methods cross-sectional observational study, performed between January and July 2012, analyzing all patients admitted in the service that met the inclusion criteria. A retrospective review of records was performed, noting demographic variables, comorbidities and tumor-related variables.
Results 150 records were analyzed, of which 53.3% were males and mean age was 63 (± 13.01) years old. The most frequently found tumor location was the sigmoid colon and high rectum (50.67%), followed by the lower rectum (36%). Adenocarcinomas were the most prevalent histological subtype (88%), followed by epidermoid tumors (1.33%). Hereditary syndromes were identified in five patients (3.33%), with four being Familial adenomatous polyposis (FAP) and one hereditary nonpolyposis colorectal cancer (HNPCC). Among the analyzed patients, four (2.67%) had synchronous and one (0.67%) had metachronous cancer.
Conclusion the incidence of synchronous and metachronous colorectal cancer was, respectively, 2.67% and 0.67%, results that corroborate those reported in international literature.

Abstract
BACKGROUND AND AIM If patients with surgically resectable colorectal cancershave synchronous colorectal neoplasms that are difficult to remove by endoscopic mucosal resection, preemptive endoscopic submucosal dissection (ESD) can avoid excessive colorectal resection. The aim of this study was to evaluate the efficacy of the strategy of preemptive ESD and surgery for synchronous colorectal neoplasms. METHODS Patients who underwent preemptive ESD and surgery for synchronous colorectal neoplasms between September 2002 and December 2017 were enrolled in this retrospective cohort study. The proportion of cases in which extended surgery could be avoided following curative ESD was calculated. Clinicopathological characteristics were evaluated for all patients and long-term outcomes were analyzed for patients who underwent curative ESD and surgery. RESULTS A total of 45 consecutive patients with 47 endoscopically-resected lesions and 46 surgically-resected lesions were retrospectively evaluated. Curative ESD was achieved in 44 lesions (93.6%) and an extended surgical procedure could be avoided in 42 patients (93.3%). Intraoperative perforation occurred in two lesions (4.3%), delayed perforation in one lesion (2.1%), and delayed bleeding in two lesions (4.3%). Final stages were as follows: stage 0, 3 patients (7.1%); stage I, 23 patients (54.8%); stage II, 3 patients (7.1%); stage III, 12 patients (28.6%); and stage IV, 1 patient (2.4%). The 5-year overall survival rates of patients with all pathological stages, stage 0-II, and stage III-IV were 93.7%, 100%, and 79.1%, respectively. CONCLUSION The strategy of preemptive ESD and surgery for synchronous colorectal neoplasms is minimally invasive and has a favorable prognosis.

Abstract
Background The aim of this study was to evaluate the risk of development of colorectal adenomas in patients with colorectal cancer (CRC) with and without colonic diverticulosis. Methods We performed a retrospective cohort study that included patients with CRC between 2008 and 2011. All patients underwent preoperative colonoscopic and barium enema examinations. Follow-up colonoscopic examinations were performed within 1 year and between 3 and 5 years postoperatively. The incidence of colorectal adenomas was compared based on the presence or absence of diverticulosis. Additionally, multivariate logistic regression analysis was performed to identify the factors independently associated with the development of synchronous and metachronous colorectal adenomas. Results Of the 168 patients with CRC included in the study, 55 showed colonic diverticulosis. Synchronous colorectal adenomas were more common in CRC patients with diverticulosis than in those without diverticulosis (P > 0.001). Multivariate regression analysis showed that colonic diverticulosis (odds ratio (OR) 3.874, 95% confidence interval (CI) 1.843–8.144, P > 0.001) and obesity (body mass index > 25.0 kg/m2, OR 2.395, 95% CI 1.089–5.270, P = 0.030) were associated with an increased risk of synchronous colorectal adenomas. The presence of synchronous colorectal adenomas increased the risk of metachronous colorectal adenomas (OR 4.407, 95% CI 1.855–10.473, P > 0.001). Conclusions Colonic diverticulosis was associated with synchronous colorectal adenomas in patients with CRC, which is eventually increasing the risk of metachronous adenomas.

Abstract
AIM Whether some diseases are related to the occurrence of synchronous colorectal carcinoma (sCRC) is unknown. Investigating the risk factors and presentation of sCRC could aid in the treatment of patients with colorectal cancer (CRC). The prognosis of sCRC compared with that of solitary CRC remains unclear. METHODS A total of 17 093 CRC patients were recruited between 1st January 1995 and 31th December 2016. The risk factors of sCRC development were assessed using univariate and multivariate logistic regression. The effect of sCRC on survival was analysed using the multivariate Cox regression model. RESULTS The prevalence of sCRC was 5.6% in this study. The independent risk factors of sCRC development were advanced age (P < 0.001), male sex (P < 0.001), hereditary cancer (P < 0.001), hypertension (P < 0.001) and liver cirrhosis (P = 0.024). Compared with solitary CRC, a higher number of patients with sCRC presented with an abnormal carcinoembryonic antigen (CEA) level (P = 0.011), anaemia (P < 0.001) and hypoalbuminemia (P < 0.001). Multivariate analysis revealed that sCRC was a significant factor for poor survival in patients at TNM Stage I [hazard ratio (HR) = 1.86; P < 0.001], Stage II (HR = 1.65; P < 0.001) and Stage III (HR = 1.40; P < 0.001). CONCLUSIONS In addition to hypertension and liver cirrhosis, other risk factors for sCRC were identified in this study. The prognosis of patients with sCRC was significantly worse than that of those with solitary CRC through TNM Stages I to III. Anaemia, abnormal CEA and hypoalbuminemia were more commonly seen in patients with sCRC.

Abstract
OBJECTIVES The objective of our study was to systematically review the evidence about synchronous colorectal cancer diagnosed with or without computed tomography colonography (CTC). MATERIALS AND METHODS Two systematic searches were performed (PubMed and EMBASE) for studies reporting the prevalence of synchronous colorectal cancer (CRC): one considering patients who underwent CTC and the another one considering patients who did not undergo CTC. A three-level analysis was performed to determine the prevalence of patients with synchronous CRC in both groups of studies. Heterogeneity was explored for multiple variables. Pooled prevalence and 95% confidence interval (CI) were calculated. A quality assessment (STROBE) was done for the studies. RESULTS For CTC studies, among 2645 articles initially found, 21 including 1673 patients, published from 1997 to 2018, met the inclusion criteria. For non-CTC studies, among 6192 articles initially found, 27 including 111,873 patients published from 1974 to 2015 met the inclusion criteria. The pooled synchronous CRC prevalence was 5.7% (95% CI 4.7%-7.1%) for CTC studies, and 3.9% (95% CI 3.3%-4.4%) for non-CTC studies, with a significant difference (p = 0.004). A low heterogeneity was found for the CTC group (I2 = 10.3%), whereas a high heterogeneity was found in the non-CTC group of studies (I2 = 93.5%), and no significant explanatory variables were found. Of the 22 STROBE items, a mean of 18 (82%) was fulfilled by CTC studies, and a mean of 16 (73%) by non-CTC studies. CONCLUSIONS The prevalence of synchronous CRC was about 4-6%. The introduction of CTC is associated with a significant increase of the prevalence of synchronous CRCs.

Abstract
BACKGROUND The incidence of malignant synchronous colorectal tumors (SCRT) is between 2% and 5%, and the association of synchronous adenomatous polyps in colon cancer has been reported to be 15%-50%. Surgical resection is the primary treatment option for SCRT not amendable to endoscopic resection. Lesions in adjacent segments are usually treated with more extensive resection; however, there is still some controversy on how to best treat synchronous lesions in separate segments, especially when the rectum is involved. In this study, we aimed to report the outcome of patients with SCRT treated by laparoscopic colectomy combined with Transanal Endoscopic Microsurgery. METHODS Data pertaining patients undergoing combined colectomy and Transanal Endoscopic Microsurgery (TEM) between 2004 and 2014 were retrospectively collected. RESULTS 141 TEM performed in the study period, 9 (6.5%) with combined laparoscopic colectomy were included. Mean age was 69.1 ± 10.6 years. There were 6 (66%) right, 2 (22%) left, and one (11%) sigmoid colectomy. All rectal lesions were benign adenomas, with mean tumor size 2.5 cm, and distance from the verge 9 ± 2.5 cm. Lesions were located in lateral rectal wall in 4, posterior in 4, and anterior in one case. Seven patients had the colectomy before TEM, and 2 had the TEM first. Mean operative time was 245 minutes (range 185-313) for the combined procedures. Median time of hospitalization was 6 days (range 4-11). Six patients (66%) had prolonged postoperative diarrhea. The final rectal pathology reports were adenoma with high-grade dysplasia (HGD) in 5 patients and adenoma with low-grade dysplasia in four cases. The colon pathology was T1 N0 in 3, T2 N0 in one, T3 N1 in one, adenoma with HGD in 2, and no residual tumor in 2 patients. Two patients underwent re-TEM for recurrent adenoma of rectum at 14 and 18 months postoperatively. CONCLUSION The combination of TEM with laparoscopic colectomy is feasible and should be kept in mind as an alternative procedure in case of SCRT. However, more strict selection criteria should be considered and the disadvantages should be discussed with the patient.

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.

Hand-Assisted Laparoscopic (HAL) Multiple Segmental Colorectal Resections: Are They Feasible and Safe? Int Surg 2015; 100:632-7. [PMID: 25875544 DOI: 10.9738/intsurg-d-14-00208.1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/14/2023] Open
Abstract
The objective of this study was to evaluate the short-term outcomes of synchronous hand-assisted laparoscopic (HAL) segmental colorectal resections. The surgical options for synchronous colonic pathology include extensive colonic resection with single anastomosis, multiple synchronous segmental resections with multiple anastomoses, or staged resections. Traditionally, multiple open, synchronous, segmental resections have been performed. There is a lack of data on HAL multiple segmental colorectal resections. A retrospective chart review was compiled on all patients who underwent HAL synchronous segmental colorectal resections by all the colorectal surgeons from our Group during the period of 1999 to 2014. Demographics, operative details, and short-term outcomes are reported. During the period, 9 patients underwent HAL synchronous multiple segmental colorectal resections. There were 5 women and 4 men, with median age of 54 (24-83) years and median BMI of 24 (19.8-38.7) kg/m(2). Two patients were on long-term corticosteroid therapy. The median operative time was 210 (120-330) minutes and median operative blood loss was 200 (75-300) mLs. The median duration for return of bowel function was 2 days and the median length of stay was 3.5 days. We had 2 minor wound infections. There were no deaths. Synchronous segmental colorectal resections with anastomoses using the hand-assisted laparoscopic technique are safe. Early conversion to open and use of stomas are advisable in challenging cases.

World J Gastroenterol 2014; 20:10570-10576. [PMID: 25132777 PMCID: PMC4130868 DOI: 10.3748/wjg.v20.i30.10570] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2014] [Revised: 04/06/2014] [Accepted: 05/19/2014] [Indexed: 02/07/2023] Open
Abstract
AIM: To evaluate the feasibility of a preoperative colonoscopy through a self-expendable metallic stent (SEMS) and to identify the factors that affect complete colonoscopy.
METHODS: A total of 48 patients who had SEMS placement because of acute malignant colonic obstruction underwent preoperative colonoscopy. After effective SEMS placement, patients who showed complete resolution of radiological findings and clinical signs of acute colon obstruction underwent a standard bowel preparation. Preoperative colonoscopy was then performed using a standard colonoscope. If the passage of colonoscope was not feasible gastroscope was used. After colonoscopy, cecal intubation time, grade of bowel preparation, tumor location, stent location, presence of synchronous polyps or cancer, damage to colonoscopy and bleeding, and stent migration after colonoscopy were recorded.
RESULTS: Complete evaluation with colonoscope was possible in 30 patients (62.5%). In this group, adenoma was detected in 13 patients (43.3%). The factors that affected complete colonoscopy were also analyzed: Tumor location at an angle; stent placement at an angle; and stent expansion diameter, which affected complete colonoscopy significantly. However in multivariate analysis, stent expansion diameter was the only significant factor that affected complete colonoscopy. Complete evaluation using additional gastroscope was feasible in 42 patients (87.5%).
CONCLUSION: Preoperative colonoscopy through the colonic stent using only conventional colonoscope was unfavorable. The narrow expansion diameter of the stent may predict unfavorable outcome. In such a case, using small caliber scope should be considered and may expect successful outcome.

Abstract
Synchronous colorectal carcinoma refers to more than one primary colorectal carcinoma detected in a single patient at initial presentation. A literature review has shown that the prevalence of the disease is approximately 3.5% of all colorectal carcinomas. This disease has a male to female ratio of 1.8:1. The mean age at presentation of patients with synchronous colorectal cancer is in the early half of the seventh decade. Patients with inflammatory bowel diseases (ulcerative colitis and Crohn’s disease), hereditary non-polyposis colorectal cancer, familial adenomatous polyposis and serrated polyps/hyperplastic polyposis are known to have a higher risk of synchronous colorectal carcinoma. These predisposing factors account for slightly more than 10% of synchronous colorectal carcinomas. Synchronous colorectal carcinoma is more common in the right colon when compared to solitary colorectal cancer. On pathological examination, some synchronous colorectal carcinomas are mucinous adenocarcinomas. They are usually associated with adenomas and metachronous colorectal carcinomas. Most of the patients with synchronous colorectal cancer have two carcinomas but up to six have been reported in one patient. Patients with synchronous colorectal carcinoma have a higher proportion of microsatellite instability cancer than patients with a solitary colorectal carcinoma. Also, limited data have revealed that in many synchronous colorectal carcinomas, carcinomas in the same patient have different patterns of microsatellite instability status, p53 mutation and K-ras mutation. Overall, the prognosis of patients with synchronous colorectal carcinoma is not significantly different from that in patients with solitary colorectal carcinoma, although a marginally better prognosis has been reported in patients with synchronous colorectal carcinoma in some series. A different management approach and long-term clinical follow-up are recommended for some patients with synchronous colorectal cancer.

Abstract
Background The Canadian province of Manitoba covers a large geographical area but only has one major urban center, Winnipeg. We sought to determine if regional differences existed in the quality of colorectal cancer care in a publicly funded health care system. Methods This was a population-based historical cohort analysis of the treatment and outcomes of Manitobans diagnosed with colorectal cancer between 2004 and 2006. Administrative databases were utilized to assess quality of care using published quality indicators. Results A total of 2,086 patients were diagnosed with stage I to IV colorectal cancer and 42.2% lived outside of Winnipeg. Patients from North Manitoba had a lower odds of undergoing major surgery after controlling for other confounders (odds ratio (OR): 0.48, 95% confidence interval (CI): 0.26 to 0.90). No geographic differences existed in the quality measures of 30-day operative mortality, consultations with oncologists, surveillance colonoscopy, and 5-year survival. However, there was a trend towards lower survival in North Manitoba. Conclusion We found minimal differences by geography. However, overall compliance with quality measures is low and there are concerning trends in North Manitoba. This study is one of the few to evaluate population-based benchmarks for colorectal cancer therapy in Canada.

Abstract
BACKGROUND The liver is the most common target organ in the metastasis of colorectal cancer (CRC). Synchronous liver metastases may confer a poorer prognosis than metachronous metastases, and genetic alterations and an inflammatory response have also been associated with a poor prognosis in cases of a liver metastasis arising from CRC. However, few studies have examined the relationship between KRAS mutations and inflammatory status in CRC, especially with respect to liver metastases. METHODS The effect of the activated mitogen-activated protein kinase pathway and another protein involved in inflammation, C-reactive protein, in liver metastases were examined. We aimed to determine the impact of the CRP-specific single nucleotide polymorphism (SNP) rs7553007 in liver metastasis on the CRC-specific survival (CSS) of patients after colorectal liver metastasectomy. RESULTS We found no significant differences in genotype distributions and allele frequencies at the CRP SNP rs7553007 between CRC patients with liver metastasis and the control group. CSS rates were low in the subgroup of patients with synchronous metastasis with the A-allele (A/A and A/G) at rs7553007 or mutated KRAS/BRAF in liver metastatic specimens. Furthermore, the CRP SNP rs7553007 (hazard ratio [HR] = 1.101; 95% confidence interval [CI] = 1.011-1.200; P = 0.027) and KRAS/BRAF mutations (HR = 2.377; 95% CI = 1.293-4.368; P = 0.005) remained predictive for the CSS of CRC patients with synchronous liver metastasis in multivariate analysis. CONCLUSIONS Both the CRP SNP rs7553007 and KRAS/BRAF mutations were independent prognostic factors for CRC patients with synchronous liver metastasis.

Abstract
Hereditary nonpoliposis colorectal cancers (HNPCC) make up 2-7% of colorectal cancer (CRC) cases. CRC's in these group of patients are usually located in proxymal colon. The incidence of syncronic metacron CRC is 18%. The incidence of having different hystopathological types for these group of tumors varies between 3-9%. APC, p53 and K-ras gene mutations may be seen in HNPCC's. The least frequent mutation is the mutation on K-ras gene. In this report, a syncronic metacron CRC with different hystopathological type and K-ras gene mutation localised in transverse and left colon that has developed on the basis of HNPCC is discussed.

Abstract
BACKGROUND The contribution of chromosomal instability, microsatellite instability, and epigenetic instability to the development of synchronous colorectal carcinomas is controversial. OBJECTIVE This study aimed to investigate the relative roles of microsatellite instability and epigenetic instability in the development of synchronous colorectal cancers. DESIGN This was a retrospective study of medical records with histologic, immunohistochemical, and molecular examination of stored tissue samples. SETTING The study took place at Seoul National University Hospital, Korea. PATIENTS A total of 46 patients with synchronous colorectal cancers and 105 patients with solitary colorectal cancers were included. MAIN OUTCOME MEASURES Clinicopathologic and molecular characteristics including microsatellite instability, mismatch repair gene expression, CpG island methylator phenotype, and mutation of KRAS and BRAF were analyzed. RESULTS Patients with synchronous tumors were more likely to be men than those with solitary tumors and had a tendency toward colocalization of individual tumors in the left or right colon. MSI-deficient cancers were more frequent in synchronous than in solitary cancers. The frequencies of CpG island methylator phenotype-high and KRAS and BRAF mutations were not different between synchronous and solitary cancers. No differences between synchronous cancers and solitary cancers were observed in overall survival or progression-free survival. Within the synchronous cancer group, patients with individual tumors discordant for microsatellite instability status had the worst clinical outcome, whereas those with individual tumors concordant for microsatellite instability-deficient status had the best clinical outcome. LIMITATIONS The study was limited by its retrospective nature. Molecular analysis was performed only on cancerous lesions. CONCLUSIONS Our findings suggest that microsatellite instability plays a more important role than does epigenetic instability in the development of synchronous colorectal cancers, and that information regarding concordant or discordant microsatellite instability status between individual tumors might help to predict clinical outcome of synchronous colorectal cancers.

Abstract
BACKGROUND A noticeable proportion of colorectal cancer (CRC) patients are diagnosed with synchronous CRC. Large population-based studies on the incidence, risk factors and prognosis of synchronous CRC are, however, scarce, and are needed for better determination of risks of synchronous CRC in patients diagnosed with colonic neoplasia. METHODS All newly diagnosed CRC between 1995 and 2006 were obtained from the Rotterdam Cancer Registry in The Netherlands, and studied for synchronous CRC. RESULTS Of the 13,683 patients diagnosed with CRC, 534 patients (3.9%) were diagnosed with synchronous CRC. The risk of having synchronous CRC was significantly higher in men (OR 1.54, 95% CI 1.29-1.84) and in patients aged >70 years (OR 1.83, 95% CI 1.39-2.40). Synchronous CRC patients had a significantly higher risk of distant metastases (OR 1.69, 95% CI 1.27-2.26). In 34% (184/534) the two tumours were located in different surgical segments. Five-year relative survival of synchronous CRC was similar to patients with solitary CRC after multivariate adjustment for the presence of distant metastases. CONCLUSION One out of 25 patients diagnosed with CRC presents with synchronous CRC. In the multivariate analysis, survival of patients with synchronous CRC was similar to patients with solitary CRC, when corrected for the presence of distant metastases at first presentation. One third of the synchronous CRC were located in different surgical segments, which stresses the importance of performing total colon examination preferably prior to surgery.

Abstract
Synchronous colorectal neoplasias are defined as 2 or more primary tumors identified in the same patient and at the same time. The most voluminous synchronous cancer is called "first primitive" or "index" cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias.Since January 2001 till December 2009, 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia; 128 were right colon cancers, 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies (112 right, 67 left colectomies and 45 anterior resections of rectum), 91 Transanal Endoscopic Microsurgical Excisions (TEM) and 53 Trans Anal Excisions (TAE). In the same observation period 6 patients, 4 males and 2 females, were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time, with a shorter post-operative hospitalization and minor complications. According to our experience, laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate.

Abstract
BACKGROUND & AIMS Synchronous colorectal neoplasias (2 or more primary carcinomas identified in the same patient) are caused by common genetic and environmental factors and can be used to study the field effect. Synchronous colon cancers have not been compared with control solitary cancers in a prospective study. METHODS We analyzed data collected from 47 patients with synchronous colorectal cancers and 2021 solitary colorectal cancers (controls) in 2 prospective cohort studies. Tumors samples were analyzed for methylation in LINE-1 and 16 CpG islands (CACNA1G, CDKN2A [p16], CRABP1, IGF2, MLH1, NEUROG1, RUNX3, SOCS1, CHFR, HIC1, IGFBP3, MGMT, MINT1, MINT31, p14 [ARF], and WRN); microsatellite instability (MSI); the CpG island methylator phenotype (CIMP); 18q loss of heterozygosity; KRAS, BRAF, and PIK3CA mutations; and expression of beta-catenin, p53, p21, p27, cyclin D1, fatty acid synthase, and cyclooxygenase-2. RESULTS Compared with patients with solitary colorectal cancer, synchronous colorectal cancer patients had reduced overall survival time (log-rank, P = .0048; hazard ratio [HR], 1.71; 95% confidence interval [CI]: 1.17-2.50; P = .0053; multivariate HR, 1.47; 95% CI: 1.00-2.17; P = .049). Compared with solitary tumors, synchronous tumors more frequently contained BRAF mutations (P = .0041), CIMP-high (P = .013), and MSI-high (P = .037). Methylation levels of LINE-1 (Spearman r = 0.82; P = .0072) and CpG island methylation (P < .0001) correlated between synchronous cancer pairs from the same individuals. CONCLUSIONS Synchronous colorectal cancers had more frequent mutations in BRAF, were more frequently CIMP- and MSI-high, and had a worse prognosis than solitary colorectal cancers. Similar epigenomic and epigenetic events were frequently observed within a synchronous cancer pair, suggesting the presence of a field defect.

Abstract
RATIONALE AND OBJECTIVES It is well known that synchronous cancers (incidence, 2%-11%) and polyps (incidence, 12%-58%) occur in patients with colorectal cancer. Magnetic resonance colonography (MRC) seems like the obvious choice as a diagnostic tool in preoperative evaluation, because it is noninvasive, and most of the colon can be evaluated. Furthermore, it has higher patient acceptance, and no sedation or radiation is used. The purpose of this study was to determine the feasibility of performing MRC preoperatively in an everyday clinical situation in a group of patients who were not offered a full conventional colonoscopy or in whom full conventional colonoscopy was not possible. MATERIALS AND METHODS In a 13-month period, 47 patients diagnosed with rectal or sigmoid colon cancer scheduled for operation were included in the study. MRC was performed with bowel purgation either the night before surgery or as ambulatory MRC the week before surgery. RESULTS Full MRC was performed in 98% of the patients. In four patients, 12 synchronous lesions (one cancer, two plaques of carcinosis, and nine adenomas) were found. One flat adenoma and five small polyps were missed by MRC and perioperative palpation but found on postoperative colonoscopy. The findings resulted in altered operative strategies in three patients. CONCLUSION This study shows the feasibility and potential gain of preoperative MRC in patients with sigmoid colon cancer or rectal cancer.

Abstract
BACKGROUND AND AIMS Synchronous cancers (SC) are well known (2-11%) in patients with colorectal carcinoma (CRC). One study has shown that intraoperative palpation can miss up to 69% of the SC while other studies have shown altered planned surgical procedure due to preoperatively diagnosed synchronous lesions in 11-44%. The purpose of this study was to review all patients having surgery for CRC in our department since 2001, and to evaluate the extent of the perioperative colonic evaluation. MATERIALS AND METHODS The records of all patients operated for CRC between Jan. 2001 and Dec. 2007 in our department were reviewed. Only patients with CRC were included. Information regarding pre-, per- and postoperative colonic evaluation were obtained and occurrences of SC were evaluated. RESULTS Of the 534 patients included 124 (23%) patients had an impassable stenosis. Full preoperative colonic evaluation (FPCE) were done in 305 (26%) patients without stenosis. In 36 patients 39 SC were diagnosed. Seven SC were diagnosed postoperatively, of which five patients never had a FPCE. Three of these five patients had an inoperable SC, one patient died due to anastomosis leakage following re-operation and one patient had pulmonary embolism as a complication to re-operation. CONCLUSIONS The results show that many patients (78%) never underwent FPCE, but also that many of these patients never had a full postoperative colonic evaluation. SC being overlooked can lead to increased morbidity and the possibility of advanced staging of the cancer which is also exemplified in this study.

Abstract
BACKGROUND The aim of this population-based study was to report on the incidence, treatment and prognosis of synchronous colorectal carcinomas. METHODS Data were obtained from the population-based cancer registry of Burgundy. RESULTS Between 1976 and 2004, 15 562 colorectal cancers were diagnosed. Some 3.8 per cent of patients had synchronous colorectal cancers. The risk of having synchronous cancers was higher in men (odds ratio (OR) 1.41 (95 per cent confidence interval (c.i.) 1.19 to 1.68)), when associated adenomas were present (OR 2.02 (95 per cent c.i. 1.69 to 2.41)), when there were adenomatous remnants on pathological examination (OR 2.10 (95 per cent c.i. 1.73 to 2.55)) and in patients aged over 75 years (OR 1.31 (95 per cent c.i. 1.08 to 1.59)). Synchronous tumours were more often located on the same intestinal segment, although the correlation was weak (kappa = 0.26). Resection for cure was performed in 74.8 per cent of synchronous cancers and 72.0 per cent of single cancers (P = 0.131). Five-year relative survival for synchronous (48.7 per cent) and single (48.3 per cent) cancers was almost identical. Stage, age, associated adenomas and adenomatous remnants were independent prognostic factors. CONCLUSION Synchronous colorectal cancers convey a similar prognosis to single tumours. Men and patients aged over 65 years with associated adenomas are more prone to multiple colorectal cancers.

Abstract
PURPOSE An individual with colorectal cancer has a 3 percent risk of synchronous colonic neoplasia and further 2 to 3 percent risk of metachronous cancer, a risk that has prompted colonic surveillance. The appendix has a similar mucosal pattern to the colon and it has been hypothesized that appendicular adenocarcinoma may account for 1 percent of all colorectal malignancies. A special interest of the senior author in appendiceal and rectal cancer has prompted routine removal of the appendix in all cases undergoing surgery for colorectal cancer. METHODS Consecutive patients undergoing left colectomy or anterior resection for colorectal cancer had coincidental appendectomy with the specimen pathologically analyzed. A retrospective review of the case notes and histopathology was performed. Data also were collected for patients who had right hemicolectomy for colonic carcinoma. RESULTS In total, 169 patients under the care of a single surgeon had colorectal cancer resection between April 2002 and April 2005: 63 patients had right hemicolectomy, 29 had left hemicolectomy, and 77 had rectal cancer resection. Seven of 169 appendices had abnormalities: 3 mucinous cystadenomas, 2 cystadenocarcinomas, 1 carcinoid tumor, and 1 villous adenoma. CONCLUSIONS Patients having colorectal cancer resection for adenocarcinoma should have appendicectomy performed. Synchronous pathology was found in 4.1 percent in this series. Metachronous neoplasia is a risk in the retained appendix in patients with colorectal cancer. Routine postoperative surveillance cannot assess the appendiceal mucosa, so there is little justification for not taking the opportunity to eliminate the possibility of future appendicitis or neoplasia.

Abstract
BACKGROUND To assess the usefulness of air-inflated magnetic resonance colonography (MRC) in patients with incomplete conventional colonoscopy (CC). METHODS From September 2001 to December 2004, 51 patients (25 male and 26 female, age range 32 to 85 years) with incomplete colonoscopy were recruited to have MRC performed. Half-fourier single short turbo spin echo (HASTE) axial, coronal, and three dimensional fat suppressed gradient echo sequence (VIBE) coronal images in both the prone and supine positions were performed for each patient. MRC was reviewed by two radiologists for detection of synchronous colonic lesion. The location and size of lesions were recorded and were compared with the findings of CC. Patients were managed according to the clinical situation and intraoperative findings were compared with MRC findings. Follow-up colonoscopy was performed in 29 patients. The follow-up colonoscopy findings were then compared with the MRC findings. RESULTS Forty-four patients had incomplete colonoscopy because of an obstructing tumor. The other seven patients had incomplete colonoscopy because of excessive bowel looping. Apart from one patient suffering from chronic obstructive airway disease with resulting nondiagnostic MRC, all other patients had MRC successfully performed. Each colon was divided into six bowel segments for analysis. All 300 segments were of diagnostic quality and were assessed by the MRC. MRC correctly identified all 44 obstructing tumors demonstrated by initial CC. Synchronous tumors in proximal colonic segments were identified in two patients by MRC. In addition, MRC identified two colonic tumors located in bowel segments inaccessible by CC because of excessive looping. CONCLUSIONS MRC is useful for detection of colonic pathology and assessment of proximal colon in patients with colonic cancer after incomplete colonoscopy.
