Abstract
These consensus guidelines were jointly commissioned by the British Society of Gastroenterology (BSG), the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and Public Health England (PHE). They provide an evidence-based framework for the use of surveillance colonoscopy and non-colonoscopic colorectal imaging in people aged 18 years and over. They are the first guidelines that take into account the introduction of national bowel cancer screening. For the first time, they also incorporate surveillance of patients following resection of either adenomatous or serrated polyps and also post-colorectal cancer resection. They are primarily aimed at healthcare professionals, and aim to address:Which patients should commence surveillance post-polypectomy and post-cancer resection?What is the appropriate surveillance interval?When can surveillance be stopped? two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps The Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument provided a methodological framework for the guidelines. The BSG's guideline development process was used, which is National Institute for Health and Care Excellence (NICE) compliant.two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps The key recommendations are that the high-risk criteria for future colorectal cancer (CRC) following polypectomy comprise either:two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps This cohort should undergo a one-off surveillance colonoscopy at 3 years. Post-CRC resection patients should undergo a 1 year clearance colonoscopy, then a surveillance colonoscopy after 3 more years.

Prognostic impact of preoperatively elevated and postoperatively normalized carcinoembryonic antigen levels following curative resection of stage I-III rectal cancer. Cancer Med 2019; 9:653-662. [PMID: 31799750 PMCID: PMC6970051 DOI: 10.1002/cam4.2758] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 10/24/2019] [Accepted: 11/21/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Preoperative and early postoperative serum carcinoembryonic antigen (CEA) levels are known prognostic factors in rectal cancer. Recently, a large-scale study on colon cancer revealed that "preoperatively elevated and postoperatively normalized CEA levels" is not an indicator of poor prognosis. However, whether this hold true in rectal cancer patients is unknown. This study aimed to investigate the prognostic significance of preoperatively elevated and postoperatively normalized CEA levels in rectal cancer patients undergoing curative resection. METHODS Subjects were consecutive stage I-III rectal cancer patients who underwent curative resection without preoperative treatment at National Cancer Center Hospital between 2000 and 2015. Overall survival (OS) and the hazard function of recurrence or death were analyzed according to the CEA levels, as follows: normal preoperative CEA (normal group), preoperatively elevated but postoperatively normalized CEA (normalized group), and preoperatively and postoperatively elevated CEA (elevated group). RESULTS The normalized group (n =235) had worse OS (HR 1.49, 95% CI 1.08-2.04; P = .0142) compared to the normal group (n = 1208), and better OS compared to the elevated group (n = 47) (HR 0.53, 95% CI 0.31-0.91; P = .0208). The elevated group had the highest and earliest peak in hazard function, followed by the normalized group and the normal group, with median times to recurrence of 8.8, 15.5, and 18.5 months, respectively (P = .0223). CONCLUSIONS Prognosis after resection of rectal cancer was worse in patients with preoperatively elevated and postoperatively normalized CEA compared to those with normal preoperative CEA. Patients with elevated preoperative CEA might require intensive follow-up even if levels normalize after resection, especially in earlier periods, for early detection of recurrence.

Abstract
Carcinoembryonic antigen (CEA) is not normally produced in significant quantities after birth but is elevated in colorectal cancer. The aim of this review was to define the current role of CEA and how best to investigate patients with elevated CEA levels. A systematic review of CEA was performed, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were identified from PubMed, Cochrane library, and controlled trials registers. We identified 2,712 papers of which 34 were relevant. Analysis of these papers found higher preoperative CEA levels were associated with advanced or metastatic disease and thus poorer prognosis. Postoperatively, failure of CEA to return to normal was found to be indicative of residual or recurrent disease. However, measurement of CEA levels alone was not sufficient to improve survival rates. Two algorithms are proposed to guide investigation of patients with elevated CEA: one for patients with elevated CEA after CRC resection, and another for patients with de novo elevated CEA. CEA measurement has an important role in the investigation, management and follow-up of patients with colorectal cancer.

Abstract
BACKGROUND Most cancer survivors receive follow-up care after completion of treatment with the primary aim of detecting recurrence. Traditional follow-up consisting of fixed visits to a cancer specialist for examinations and tests are expensive and may be burdensome for the patient. Follow-up strategies involving non-specialist care providers, different intensity of procedures, or addition of survivorship care packages have been developed and tested, however their effectiveness remains unclear. OBJECTIVES The objective of this review is to compare the effect of different follow-up strategies in adult cancer survivors, following completion of primary cancer treatment, on the primary outcomes of overall survival and time to detection of recurrence. Secondary outcomes are health-related quality of life, anxiety (including fear of recurrence), depression and cost. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, four other databases and two trials registries on 11 December 2018 together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA We included all randomised trials comparing different follow-up strategies for adult cancer survivors following completion of curatively-intended primary cancer treatment, which included at least one of the outcomes listed above. We compared the effectiveness of: 1) non-specialist-led follow-up (i.e. general practitioner (GP)-led, nurse-led, patient-initiated or shared care) versus specialist-led follow-up; 2) less intensive versus more intensive follow-up (based on clinical visits, examinations and diagnostic procedures) and 3) follow-up integrating additional care components relevant for detection of recurrence (e.g. patient symptom education or monitoring, or survivorship care plans) versus usual care. DATA COLLECTION AND ANALYSIS We used the standard methodological guidelines by Cochrane and Cochrane Effective Practice and Organisation of Care (EPOC). We assessed the certainty of the evidence using the GRADE approach. For each comparison, we present synthesised findings for overall survival and time to detection of recurrence as hazard ratios (HR) and for health-related quality of life, anxiety and depression as mean differences (MD), with 95% confidence intervals (CI). When meta-analysis was not possible, we reported the results from individual studies. For survival and recurrence, we used meta-regression analysis where possible to investigate whether the effects varied with regards to cancer site, publication year and study quality. MAIN RESULTS We included 53 trials involving 20,832 participants across 12 cancer sites and 15 countries, mainly in Europe, North America and Australia. All the studies were carried out in either a hospital or general practice setting. Seventeen studies compared non-specialist-led follow-up with specialist-led follow-up, 24 studies compared intensity of follow-up and 12 studies compared patient symptom education or monitoring, or survivorship care plans with usual care. Risk of bias was generally low or unclear in most of the studies, with a higher risk of bias in the smaller trials. Non-specialist-led follow-up compared with specialist-led follow-up It is uncertain how this strategy affects overall survival (HR 1.21, 95% CI 0.68 to 2.15; 2 studies; 603 participants), time to detection of recurrence (4 studies, 1691 participants) or cost (8 studies, 1756 participants) because the certainty of the evidence is very low. Non-specialist- versus specialist-led follow up may make little or no difference to health-related quality of life at 12 months (MD 1.06, 95% CI -1.83 to 3.95; 4 studies; 605 participants; low-certainty evidence); and probably makes little or no difference to anxiety at 12 months (MD -0.03, 95% CI -0.73 to 0.67; 5 studies; 1266 participants; moderate-certainty evidence). We are more certain that it has little or no effect on depression at 12 months (MD 0.03, 95% CI -0.35 to 0.42; 5 studies; 1266 participants; high-certainty evidence). Less intensive follow-up compared with more intensive follow-up Less intensive versus more intensive follow-up may make little or no difference to overall survival (HR 1.05, 95% CI 0.96 to 1.14; 13 studies; 10,726 participants; low-certainty evidence) and probably increases time to detection of recurrence (HR 0.85, 95% CI 0.79 to 0.92; 12 studies; 11,276 participants; moderate-certainty evidence). Meta-regression analysis showed little or no difference in the intervention effects by cancer site, publication year or study quality. It is uncertain whether this strategy has an effect on health-related quality of life (3 studies, 2742 participants), anxiety (1 study, 180 participants) or cost (6 studies, 1412 participants) because the certainty of evidence is very low. None of the studies reported on depression. Follow-up strategies integrating additional patient symptom education or monitoring, or survivorship care plans compared with usual care: None of the studies reported on overall survival or time to detection of recurrence. It is uncertain whether this strategy makes a difference to health-related quality of life (12 studies, 2846 participants), anxiety (1 study, 470 participants), depression (8 studies, 2351 participants) or cost (1 studies, 408 participants), as the certainty of evidence is very low. AUTHORS' CONCLUSIONS Evidence regarding the effectiveness of the different follow-up strategies varies substantially. Less intensive follow-up may make little or no difference to overall survival but probably delays detection of recurrence. However, as we did not analyse the two outcomes together, we cannot make direct conclusions about the effect of interventions on survival after detection of recurrence. The effects of non-specialist-led follow-up on survival and detection of recurrence, and how intensity of follow-up affects health-related quality of life, anxiety and depression, are uncertain. There was little evidence for the effects of follow-up integrating additional patient symptom education/monitoring and survivorship care plans.

Abstract
Despite advances in surgical techniques and chemoradiation therapy, recurrent rectal cancer remains a cause of morbidity and mortality. After successful treatment of rectal cancer, patients are typically enrolled in a surveillance strategy that includes imaging as studies have shown improved prognosis when recurrent rectal cancer is detected during imaging surveillance versus based on development of symptoms. Additionally, patients who experience a complete clinical response with chemoradiation therapy may elect to enroll in a "watch-and-wait" strategy that includes imaging surveillance rather than surgical resection. Factors that increase the likelihood of recurrence, patterns of recurrence, and the imaging appearances of recurrent rectal cancer are reviewed with a focus on CT, PET CT, and MR imaging.

Abstract
Lung is the most common metastatic site for tumors other than the liver. Pulmonary metastasectomy is also one of the common operations in thoracic surgery. However, the effect of pulmonary metastasectomy is controversial. As far as the current experience is concerned, patients with pulmonary metastases with long disease free interval, low-grade malignant tumor and complete excision have the greatest benefit from metastasectomy. This review is about the progress of surgical treatment of pulmonary metastases.

Abstract
BACKGROUND This is the fourth update of a Cochrane Review first published in 2002 and last updated in 2016.It is common clinical practice to follow patients with colorectal cancer for several years following their curative surgery or adjuvant therapy, or both. Despite this widespread practice, there is considerable controversy about how often patients should be seen, what tests should be performed, and whether these varying strategies have any significant impact on patient outcomes. OBJECTIVES To assess the effect of follow-up programmes (follow-up versus no follow-up, follow-up strategies of varying intensity, and follow-up in different healthcare settings) on overall survival for patients with colorectal cancer treated with curative intent. Secondary objectives are to assess relapse-free survival, salvage surgery, interval recurrences, quality of life, and the harms and costs of surveillance and investigations. SEARCH METHODS For this update, on 5 April 2109 we searched CENTRAL, MEDLINE, Embase, CINAHL, and Science Citation Index. We also searched reference lists of articles, and handsearched the Proceedings of the American Society for Radiation Oncology. In addition, we searched the following trials registries: ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. We contacted study authors. We applied no language or publication restrictions to the search strategies. SELECTION CRITERIA We included only randomised controlled trials comparing different follow-up strategies for participants with non-metastatic colorectal cancer treated with curative intent. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two review authors independently determined study eligibility, performed data extraction, and assessed risk of bias and methodological quality. We used GRADE to assess evidence quality. MAIN RESULTS We identified 19 studies, which enrolled 13,216 participants (we included four new studies in this second update). Sixteen out of the 19 studies were eligible for quantitative synthesis. Although the studies varied in setting (general practitioner (GP)-led, nurse-led, or surgeon-led) and 'intensity' of follow-up, there was very little inconsistency in the results.Overall survival: we found intensive follow-up made little or no difference (hazard ratio (HR) 0.91, 95% confidence interval (CI) 0.80 to 1.04: I² = 18%; high-quality evidence). There were 1453 deaths among 12,528 participants in 15 studies. In absolute terms, the average effect of intensive follow-up on overall survival was 24 fewer deaths per 1000 patients, but the true effect could lie between 60 fewer to 9 more per 1000 patients.Colorectal cancer-specific survival: we found intensive follow-up probably made little or no difference (HR 0.93, 95% CI 0.81 to 1.07: I² = 0%; moderate-quality evidence). There were 925 colorectal cancer deaths among 11,771 participants enrolled in 11 studies. In absolute terms, the average effect of intensive follow-up on colorectal cancer-specific survival was 15 fewer colorectal cancer-specific survival deaths per 1000 patients, but the true effect could lie between 47 fewer to 12 more per 1000 patients.Relapse-free survival: we found intensive follow-up made little or no difference (HR 1.05, 95% CI 0.92 to 1.21; I² = 41%; high-quality evidence). There were 2254 relapses among 8047 participants enrolled in 16 studies. The average effect of intensive follow-up on relapse-free survival was 17 more relapses per 1000 patients, but the true effect could lie between 30 fewer and 66 more per 1000 patients.Salvage surgery with curative intent: this was more frequent with intensive follow-up (risk ratio (RR) 1.98, 95% CI 1.53 to 2.56; I² = 31%; high-quality evidence). There were 457 episodes of salvage surgery in 5157 participants enrolled in 13 studies. In absolute terms, the effect of intensive follow-up on salvage surgery was 60 more episodes of salvage surgery per 1000 patients, but the true effect could lie between 33 to 96 more episodes per 1000 patients.Interval (symptomatic) recurrences: these were less frequent with intensive follow-up (RR 0.59, 95% CI 0.41 to 0.86; I² = 66%; moderate-quality evidence). There were 376 interval recurrences reported in 3933 participants enrolled in seven studies. Intensive follow-up was associated with fewer interval recurrences (52 fewer per 1000 patients); the true effect is between 18 and 75 fewer per 1000 patients.Intensive follow-up probably makes little or no difference to quality of life, anxiety, or depression (reported in 7 studies; moderate-quality evidence). The data were not available in a form that allowed analysis.Intensive follow-up may increase the complications (perforation or haemorrhage) from colonoscopies (OR 7.30, 95% CI 0.75 to 70.69; 1 study, 326 participants; very low-quality evidence). Two studies reported seven colonoscopic complications in 2292 colonoscopies, three perforations and four gastrointestinal haemorrhages requiring transfusion. We could not combine the data, as they were not reported by study arm in one study.The limited data on costs suggests that the cost of more intensive follow-up may be increased in comparison with less intense follow-up (low-quality evidence). The data were not available in a form that allowed analysis. AUTHORS' CONCLUSIONS The results of our review suggest that there is no overall survival benefit for intensifying the follow-up of patients after curative surgery for colorectal cancer. Although more participants were treated with salvage surgery with curative intent in the intensive follow-up groups, this was not associated with improved survival. Harms related to intensive follow-up and salvage therapy were not well reported.

Abstract
Along with the surgeon, the gastroenterologist and the general practitioner, the radiation oncologist is involved in the follow-up of patients with rectal cancer treated by radiation. Post-treatment follow-up is recommended by major professional expert groups and consists of clinical examination, monitoring of carcinoembryonic antigen, colonoscopy and computed tomography of the abdomen and pelvis. Three recent large phase III randomized trials demonstrated a lack of survival benefit from intensive follow-up strategies in comparison with minimal follow-up. However, a follow-up program is not only important for the detection of an early disease relapse but it can be also used for the identification and the management of long-term toxicity and sequalae related to rectal cancer treatment.

Abstract
BACKGROUND Intensive follow-up after surgery for colorectal cancers is common in clinical practice, but evidence of a survival benefit is limited. OBJECTIVE To conduct a systematic review and meta-analysis on the effects of follow-up strategies for nonmetastatic colorectal cancer. DATA SOURCES We searched Medline, Embase, and CENTRAL databases through May 30, 2018. STUDY SELECTION We included randomized clinical trials evaluating intensive follow-up versus less follow-up in patients with nonmetastatic colorectal cancer. INTERVENTIONS Intensive follow-up. MAIN OUTCOMES MEASURES Overall survival. RESULTS The analyses included 17 trials with a total of 8039 patients. Compared with less follow-up, intensive follow-up significantly improved overall survival in patients with nonmetastatic colorectal cancer after radical surgery (HR 0.85, 95% CI 0.74-0.97, P = 0.01; I2 = 30%; high quality). Subgroup analyses showed that differences between intensive-frequency and intensive-test follow-up (P = 0.04) and between short interval and long interval of follow-up (P = 0.02) in favor of the former one. LIMITATIONS Clinical heterogeneity of interventions. CONCLUSIONS For patients with nonmetastatic colorectal cancer after curative resection, intensive follow-up strategy was associated with an improvement in overall survival compared with less follow-up strategy. Intensive-frequency follow-up strategy was associated with a greater reduction in mortality compared with intensive-test follow-up strategy.

Abstract
BACKGROUND Intensive surveillance strategies are currently recommended for patients after curative treatment of colon cancer, with the aim of secondary prevention of recurrence. Yet, intensive surveillance has not yielded improvements in overall patient survival compared with minimal follow-up, and more intensive surveillance may be costlier. OBJECTIVE The purpose of this study was to estimate the quality-adjusted life-years, economic costs, and cost-effectiveness of various surveillance strategies after curative treatment of colon cancer. DESIGN A Markov model was calibrated to reflect the natural history of colon cancer recurrence and used to estimate surveillance costs and outcomes. SETTINGS This was a decision-analytic model. PATIENTS Individuals entered the model at age 60 years after curative treatment for stage I, II, or III colon cancer. Other initial age groups were assessed in secondary analyses. MAIN OUTCOME MEASURES We estimated the gains in quality-adjusted life-years achieved by early detection and treatment of recurrence, as well as the economic costs of surveillance under various strategies. RESULTS Cost-effective strategies for patients with stage I colon cancer improved quality-adjusted life-expectancy by 0.02 to 0.06 quality-adjusted life-years at an incremental cost of $1702 to $13,019. For stage II, they improved quality-adjusted life expectancy by 0.03 to 0.09 quality-adjusted life-years at a cost of $2300 to $14,363. For stage III, they improved quality-adjusted life expectancy by 0.03 to 0.17 quality-adjusted life-years for a cost of $1416 to $17,631. At a commonly cited willingness-to-pay threshold of $100,000 per quality-adjusted life-year, the most cost-effective strategy for patients with a history of stage I or II colon cancer was liver ultrasound and chest x-ray annually. For those with a history of stage III colon cancer, the optimal strategy was liver ultrasound and chest x-ray every 6 months with CEA measurement every 6 months. LIMITATIONS The study was limited by model structure assumptions and uncertainty around the values of the model's parameters. CONCLUSIONS Given currently available data and within the limitations of a model-based decision-analytic approach, the effectiveness of routine intensive surveillance for patients after treatment of colon cancer appears, on average, to be small. Compared with testing using lower cost imaging, currently recommended strategies are associated with cost-effectiveness ratios that indicate low value according to well-accepted willingness-to-pay thresholds in the United States.

Abstract
BACKGROUND No guidelines exist for surveillance following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for appendiceal and colorectal cancer. The primary objective was to define the optimal surveillance frequency after CRS/HIPEC. METHODS The U.S. HIPEC Collaborative database (2000-2017) was reviewed for patients who underwent a CCR0/1 CRS/HIPEC for appendiceal or colorectal cancer. Radiologic surveillance frequency was divided into two categories: low-frequency surveillance (LFS) at q6-12mos or high-frequency surveillance (HFS) at q2-4mos. Primary outcome was overall survival (OS). RESULTS Among 975 patients, the median age was 55 year, 41% were male: 31% had non-invasive appendiceal (n = 301), 45% invasive appendiceal (n = 435), and 24% colorectal cancer (CRC; n = 239). With a median follow-up time of 25 mos, the median time to recurrence was 12 mos. Despite less surveillance, LFS patients had no decrease in median OS (non-invasive appendiceal: 106 vs. 65 mos, p < 0.01; invasive appendiceal: 120 vs. 73 mos, p = 0.02; colorectal cancer [CRC]: 35 vs. 30 mos, p = 0.8). LFS patients had lower median PCI scores compared with HFS (non-invasive appendiceal: 10 vs. 19; invasive appendiceal: 10 vs. 14; CRC: 8 vs. 11; all p < 0.01). However, on multivariable analysis, accounting for PCI score, LFS was still not associated with decreased OS for any histologic type (non-invasive appendiceal: hazard ratio [HR]: 0.28, p = 0.1; invasive appendiceal: HR: 0.73, p = 0.42; CRC: HR: 1.14, p = 0.59). When estimating annual incident cases of CRS/HIPEC at 375 for non-invasive appendiceal, 375 invasive appendiceal and 4410 colorectal, LFS compared with HFS for the initial two post-operative years would potentially save $13-19 M/year to the U.S. healthcare system. CONCLUSIONS Low-frequency surveillance after CRS/HIPEC for appendiceal or colorectal cancer is not associated with decreased survival, and when considering decreased costs, may optimize resource utilization.

The Disease-Free Interval Between Resection of Primary Colorectal Malignancy and the Detection of Hepatic Metastases Predicts Disease Recurrence But Not Overall Survival. Ann Surg Oncol 2019; 26:2812-2820. [PMID: 31147988 PMCID: PMC6682566 DOI: 10.1245/s10434-019-07481-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2019] [Indexed: 12/11/2022]
Abstract
Introduction The disease-free interval (DFI) between resection of primary colorectal cancer (CRC) and diagnosis of liver metastases is considered an important prognostic indicator; however, recent analyses in metastatic CRC found limited evidence to support this notion. Objective The current study aims to determine the prognostic value of the DFI in patients with resectable colorectal liver metastases (CRLM). Methods Patients undergoing first surgical treatment of CRLM at three academic centers in The Netherlands were eligible for inclusion. The DFI was defined as the time between resection of CRC and detection of CRLM. Baseline characteristics and Kaplan–Meier survival estimates were stratified by DFI. Cox regression analyses were performed for overall (OS) and disease-free survival (DFS), with the DFI entered as a continuous measure using a restricted cubic spline function with three knots. Results In total, 1374 patients were included. Patients with a shorter DFI more often had lymph node involvement of the primary, more frequently received neoadjuvant chemotherapy for CRLM, and had higher number of CRLM at diagnosis. The DFI significantly contributed to DFS prediction (p =0.002), but not for predicting OS (p =0.169). Point estimates of the hazard ratio (95% confidence interval) for a DFI of 0 versus 12 months and 0 versus 24 months were 1.284 (1.114–1.480) and 1.444 (1.180–1.766), respectively, for DFS, and 1.111 (0.928–1.330) and 1.202 (0.933–1.550), respectively, for OS. Conclusion The DFI is of prognostic value for predicting disease recurrence following surgical treatment of CRLM, but not for predicting OS outcomes.

Abstract
BACKGROUND The best strategy for surveillance testing in stage II and III colon cancer patients following curative treatment is unknown. Previous randomized controlled trials have suffered from design limitations and yielded conflicting evidence. This observational comparative effectiveness research study was conducted to provide new evidence on the relationship between post-treatment surveillance testing and survival by overcoming the limitations of previous clinical trials. METHODS This was a retrospective cohort study of the Surveillance, Epidemiology, and End Results database combined with Medicare claims (SEER-Medicare). Stage II and III colon cancer patients diagnosed from 2002 to 2009 and between 66 to 84 years of age were eligible. Adherence to surveillance testing guidelines-including carcinoembryonic antigen, computed tomography, and colonoscopy-was assessed for each year of follow-up and overall for up to three years post-treatment. Patients were categorized as More Adherent and Less Adherent according to testing guidelines. Patients who received no surveillance testing were excluded. The primary outcome was 5-year cancer-specific survival; 5-year overall survival was the secondary outcome. Inverse probability of treatment weighting (IPTW) using generalized boosted models was employed to balance covariates between the two surveillance groups. IPTW-adjusted survival curves comparing the two groups were performed by the Kaplan-Meier method. Weighted Cox regression was used to obtain hazard ratios (HRs) with 95% confidence intervals (CIs) for the relative risk of death for the Less Adherent group versus the More Adherent group. RESULTS There were 17,860 stage II and III colon cancer cases available for analysis. Compared to More Adherent patients, Less Adherent patients experienced slightly better 5-year cancer-specific survival (HR = 0.83, 95% CI 0.76-0.90) and worse 5-year noncancer-specific survival (HR = 1.61, 95% CI 1.43-1.82) for years 2 to 5 of follow-up. There was no difference between the groups in overall survival (HR = 1.04, 95% CI 0.98-1.10). CONCLUSIONS More surveillance testing did not improve 5-year cancer-specific survival compared to less testing and there was no difference between the groups in overall survival. The results of this study support a risk-stratified, shared decision-making surveillance strategy to optimize clinical and patient-centered outcomes for colon cancer patients in the survivorship phase of care.

Abstract
AIM It is common clinical practice to follow patients for a period of years after treatment with curative intent of nonmetastatic colorectal cancer, but follow-up strategies vary widely. The aim of this systematic review was to provide an overview of recommendations on this topic in guidelines from member countries of the European Society of Coloproctology, with supporting evidence. METHOD A systematic search of Medline, Embase and the guideline databases Trip database, BMJ Best Practice and Guidelines International Network was performed. Quality assessment included use of the AGREE-II tool. All topics with recommendations from included guidelines were identified and categorized. For each subtopic, a conclusion was made followed by the degree of consensus and the highest level of evidence. RESULTS Twenty-one guidelines were included. The majority recommended that structured follow-up should be offered, except for patients in whom treatment of recurrence would be inappropriate. It was generally agreed that clinical visits, measurement of carcinoembryoinc antigen and liver imaging should be part of follow-up, based on a high level of evidence, although the frequency is controversial. There was also consensus on imaging of the chest and pelvis in rectal cancer, as well as endoscopy, based on lower levels of evidence and with a level of intensity that was contradictory. CONCLUSION In available guidelines, multimodal follow-up after treatment with curative intent of colorectal cancer is widely recommended, but the exact content and intensity are highly controversial. International agreement on the optimal follow-up schedule is unlikely to be achieved on current evidence, and further research should refocus on individualized 'patient-driven' follow-up and new biomarkers.

Abstract
Colorectal cancer (CRC) is one of the tumours with the highest incidence and mortality in the Spanish population. Nevertheless, the advances in prevention and treatment have contributed to an increased number of patients who survive for prolonged periods of time. In addition, despite recurrences, improved survival following metastasis resection is likewise on the rise. This underscores the importance of carrying out follow-up programmes even in low-risk patients for the early detection of recurrence. The main objective of this article is to provide a set of recommendations for optimising the follow-up of CRC survivors as well as for managing the sequelae that result from either pharmacological or surgical treatment.

Abstract
AIM The intensity and duration of surveillance for rectal cancer after surgical resection remain contentious. We evaluated the pattern of recurrences in a rectal cancer cohort followed up beyond 10 years. METHODS An analysis was performed on a retrospective database of 326 patients with rectal cancer who underwent curative surgical resection from 1999 to 2007. The above study duration was chosen to ensure at least 10 years of follow-up. Data on patient demographics, peri-operative details, and follow-up outcomes were extracted from the database. The pattern of recurrences and investigative modality that detected recurrences was identified. Patients were followed up until either year 2016 or the day of their demise. RESULTS Two hundred seventeen patients (66.6%) were male and 109 patients (33.3%) female. Median age was 64 years old. Close to a third of the patients received adjuvant therapy (34%). Among the 326 patients studied, 29.8% of (97/326) patients developed recurrence. 7.7% (25/326) had loco-regional recurrence while 22.1% (72/326) had distant metastasis. Median time to recurrence was 16 months (4-83) and 18 months (3-81), respectively. Computed tomography scan was the best modality to detect both loco-regional and distant recurrences (48% in loco-regional and 41.7% in distant metastasis). The most common site of distant metastasis is the lung (34.7%). The salvage rate for loco-regional and distant recurrences was 52 and 12.5%, respectively. CONCLUSION The predominant pattern of recurrence in rectal cancer is distant disease. Surveillance regimes may need to be altered to increase early detection of distant metastases.

Abstract
Colorectal cancer (CRC) is a prevalent disease and represents a major cause of morbidity and mortality in the developed world. Intensive post-treatment surveillance is routinely recommended by major expert groups for early stage (II and III) CRC survivors because previous meta-analyses showed a modest, but significant survival benefit. This practice has been recently challenged based on data emerging from several large phase III randomized trials that demonstrated a lack of survival benefit from intensive surveillance strategies. In addition, findings from cost-effectiveness analyses of such an approach are inconsistent. Data on real-world practice, specifically adherence to these follow-up guidelines, are also limited. The debate is especially controversial in resected stage IV patients where there are currently no clear guidelines for follow-up. In an era of personalized medicine, there may be a shift towards a more risk-adapted approach to better define the optimal follow-up strategy. In this article, we review the evidence and highlight the role of surveillance in CRC survivors.

Abstract
Adjuvant fluoropyrimidine-based chemotherapy has been the standard of care for resected stage III colon cancer since the 1990s; the evolution from 12 to 6 months of fluoropyrimidine therapy and the addition of oxaliplatin to fluoropyrimidine therapy have led to the current accepted standard. However, controversies remain. What is the benefit of adjuvant chemotherapy in stage II disease, and in whom? What is the optimal duration of adjuvant chemotherapy? How should patients with early-stage colon cancer be followed after surgery and adjuvant treatment? Recent evidence has emerged to help inform these important questions, including the International Duration Evaluation of Adjuvant therapy (IDEA) collaboration, which is the largest, prospective study in colon cancer with 12,834 patients. This review discusses current and future risk stratification strategies in stage II disease: the optimal duration of adjuvant oxaliplatin-containing chemotherapy in stage II and III disease according to the IDEA study, and the recent evidence and updated recommendations for surveillance of early-stage colon cancer after resection.

Abstract
BACKGROUND/AIMS To evaluate the impact of lung metastases (LM) on overall survival (OS) in well-differentiated (WD) stage IV gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) patients along with developing surveillance strategies for thoracic imaging. METHODS Thirty-four patients with LM, from 3 centres, were identified (22 small intestine/12 pancreatic; 17 grade 1/15 grade 2/2 of unknown grade). For comparison, we used 106 stage IV WD, grade 1 and 2 GEP-NEN patients with metastatic disease confined in the abdomen. RESULTS LM prevalence was 4.9% (34/692). Eleven patients (32%) presented with synchronous LM whereas 23 (68%) developed metachronous LM at a median of 25 months (range 1-150 months). Patients with metachronous LM had already established liver and/or para-aortic lymph node metastases. Eighteen of 23 patients (78%) with metachronous LM exhibited concomitant progression in the abdomen. Median OS of WD GEP-NEN patients with LM was shorter than for those with stage IV disease without extra-abdominal metastases (56 [95% CI 40.6-71.6] vs. 122.7 [95% CI 70.7-174.8] months; log-rank p = 0.001). Among patients with progressive stage IV disease, the subset of patients with LM exhibited shorter OS (log-rank p = 0.005). LM were also confirmed as an independent prognostic factor for survival in multivariable analysis (HR 0.18; 95% CI 0.07-0.45; p < 0.0001). CONCLUSION LM, although relatively rare in patients with WD stage IV GEP-NENs, may impact patients' outcome. The development of metachronous LM is associated with concomitant disease progression in established abdominal metastases in most patients. These patient-related parameters could be utilized for a stratified surveillance approach, mainly reserving thoracic imaging for GEP-NEN patients with progressive disease in the abdomen.

Abstract
Guidelines recommend surveillance after resection of colorectal cancer (CRC), but rates of adherence to surveillance are variable and have not been studied at National Cancer Institute (NCI)‐designated Comprehensive Cancer Centers. The aim of this study was to determine rates of adherence to standard postresection CRC surveillance recommendations including physician visits, carcinoembryonic antigen (CEA), computed tomography (CT), and colonoscopy after CRC resection at three NCI‐designated centers. Data on patients with resected CRC from 2010 to 2017 were reviewed. Adherence to physician visits was defined as having at least two visits within 14 months after surgical resection. CEA adherence was defined as having at least four CEA levels drawn within 14 months. CT and colonoscopy adherence were defined as completing each between 10 and 14 months from surgical resection. Chi‐square test and logistic regression analyses were performed for overall adherence and adherence to individual components. A total of 241 CRC patients were included. Overall adherence was 23%. While adherence to physician visits was over 98%, adherence to CEA levels, CT, and colonoscopy were each less than 50%. Center was an independent predictor of adherence to CEA, CT, and/or colonoscopy. Stage III disease predicted CT adherence, while distance traveled of 40 miles or less predicted colonoscopy adherence. Overall adherence to postresection CRC guideline‐recommended care is low at NCI‐designated centers. Adherence rates to surveillance vary by center, stage, and distance traveled for care. Understanding factors associated with adherence is critical to ensure CRC patients benefit from postresection surveillance.

Abstract
PURPOSE It is unclear whether obstructing colorectal cancer (CRC) has a worse prognosis than non-obstructing CRC. Of CRC patients, 10-28% present with symptoms of acute obstruction. Previous studies regarding obstruction have been primarily based on short-term outcomes, risk factors and treatment modalities. With this study, we want to determine the long-term survival of patients presenting with acute obstructive CRC. METHODS This single-centre observational retrospective cohort study includes all CRC patients who underwent surgery between December 2004 and 2010. Patients were divided into two groups: ileus and no ileus. Survival analyses were performed for both groups. Additional survival analyses were performed in patients with and without synchronous metastases. The primary outcome was survival in months. RESULTS A total of 1236 patients were included in the analyses. Ileus occurred in 178 patients (14.4%). The 5-year survival for patients with an ileus was 32% and without 60% (P < 0.01). In patients without synchronous metastases, survival with and without an ileus was 40.9 and 68.4%, respectively (P < 0.01). If ileus presentation was complicated by a colon blowout, 5-year survival decreased to 29%. No significant difference was found in patients with synchronous metastases. Survival at 5 years in this subgroup was 10 and 12% for patients with and without an ileus, respectively (P = 0.705). CONCLUSIONS Patients with obstructive CRC have a reduced short-term overall survival. Also, long-term overall survival is impaired in patients who present with acute obstructive CRC compared to patients without obstruction.

Abstract
Importance Surveillance testing is performed after primary treatment for colorectal cancer (CRC), but it is unclear if the intensity of testing decreases time to detection of recurrence or affects patient survival. Objective To determine if intensity of posttreatment surveillance is associated with time to detection of CRC recurrence, rate of recurrence, resection for recurrence, or overall survival. Design, Setting, and Participants A retrospective cohort study of patient data abstracted from the medical record as part of a Commission on Cancer Special Study merged with records from the National Cancer Database. A random sample of patients (n=8529) diagnosed with stage I, II, or III CRC treated at a Commission on Cancer-accredited facilities (2006-2007) with follow-up through December 31, 2014. Exposures Intensity of imaging and carcinoembryonic antigen (CEA) surveillance testing derived empirically at the facility level using the observed to expected ratio for surveillance testing during a 3-year observation period. Main Outcomes and Measures The primary outcome was time to detection of CRC recurrence; secondary outcomes included rates of resection for recurrent disease and overall survival. Results A total of 8529 patients (49% men; median age, 67 years) at 1175 facilities underwent surveillance imaging and CEA testing within 3 years after their initial CRC treatment. The cohort was distributed by stage as follows: stage I, 25.0%; stage II, 35.2%; and stage III, 39.8%. Patients treated at high-intensity facilities-4188 patients (49.1%) for imaging and 4136 (48.5%) for CEA testing-underwent a mean of 2.9 (95% CI, 2.8-2.9) imaging scans and a mean of 4.3 (95% CI, 4.2-4.4) CEA tests. Patients treated at low-intensity facilities-4341 patients (50.8%) for imaging and 4393 (51.5%) for CEA testing-underwent a mean of 1.6 (95% CI, 1.6-1.7) imaging scans and a mean of 1.6 (95% CI, 1.6-1.7) CEA tests. Imaging and CEA surveillance intensity were not associated with a significant difference in time to detection of cancer recurrence. The median time to detection of recurrence was 15.1 months (IQR, 8.2-26.3) for patients treated at facilities with high-intensity imaging surveillance and 16.0 months (IQR, 7.9-27.2) with low-intensity imaging surveillance (difference, -0.95 months; 95% CI, -2.59 to 0.68; HR, 0.99; 95% CI, 0.90-1.09) and was 15.9 months (IQR, 8.5-27.5) for patients treated at facilities with high-intensity CEA testing and 15.3 months (IQR, 7.9-25.7) with low-intensity CEA testing (difference, 0.59 months; 95% CI, -1.33 to 2.51; HR, 1.00; 95% CI, 0.90-1.11). No significant difference existed in rates of resection for cancer recurrence (HR for imaging, 1.22; 95% CI, 0.99-1.51 and HR for CEA testing, 1.12; 95% CI, 0.91-1.39) or overall survival (HR for imaging, 1.01; 95% CI, 0.94-1.08 and HR for CEA testing, 0.96; 95% CI, 0.89-1.03) among patients treated at facilities with high- vs low-intensity imaging or CEA testing surveillance. Conclusions and Relevance Among patients treated for stage I, II, or III CRC, there was no significant association between surveillance intensity and detection of recurrence.

Abstract
INTRODUCTION Although the colorectal cancer (CRC) mortality rate has significantly improved over the past several decades, many patients will have a recurrence following curative treatment. Despite this high risk of recurrence, adherence to CRC surveillance testing guidelines is poor which increases cancer-related morbidity and potentially, mortality. Several randomised controlled trials (RCTs) with varying surveillance strategies have yielded conflicting evidence regarding the survival benefit associated with surveillance testing. However, due to differences in study protocols and limitations of sample size and length of follow-up, the RCT may not be the best study design to evaluate this relationship. An observational comparative effectiveness research study can overcome the sample size/follow-up limitations of RCT designs while assessing real-world variability in receipt of surveillance testing to provide much needed evidence on this important clinical issue. The gap in knowledge that this study will address concerns whether adherence to National Comprehensive Cancer Network CRC surveillance guidelines improves survival. METHODS AND ANALYSIS Patients with colon and rectal cancer aged 66-84 years, who have been diagnosed between 2002 and 2008 and have been included in the Surveillance, Epidemiology, and End Results-Medicare database, are eligible for this retrospective cohort study. To minimise bias, patients had to survive at least 12 months following the completion of treatment. Adherence to surveillance testing up to 5 years post-treatment will be assessed in each year of follow-up and overall. Binomial regression will be used to assess the association between patients' characteristics and adherence. Survival analysis will be conducted to assess the association between adherence and 5-year survival. ETHICS AND DISSEMINATION This study was approved by the National Cancer Institute and the Institutional Review Board of the University of Central Florida. The results of this study will be disseminated by publishing in the peer-reviewed scientific literature, presentation at national/international scientific conferences and posting through social media.

Abstract
Metastasectomy is the most frequent surgical resection undertaken by thoracic surgeons, being the lung the second common site of metastases. The present oncological criteria for pulmonary metastasectomy are: (I) the primary cancer need to be controlled or controllable; (II) no extrathoracic metastasis-that is not controlled or controllable-exists; (III) all of the tumor must be resectable, with adequate pulmonary reserve; (IV) there are no alternative medical treatment options with lower morbidity. General favourable prognostic features in patients with pulmonary metastases are: (I) one or few metastases; (II) long disease free interval; (III) normal CEA levels in colorectal cancers. Negative predictive features in patients candidate to pulmonary metastasectomies are: (I) active primary cancer; (II) extrathoracic metastases; (III) inability to obtain surgical radicality; (IV) mediastinal lymphatic spread. The lack of controlled trials and studies limited by short follow-up and small cohorts did not allow to overcome some skepticism; moreover, the heterogeneity of these patients in terms of demographic, biologic and histologic characteristics represents a clear limit even in the largest series. On the basis of present knowledge, without results coming from on-going randomized trials, radical resection, histology, and disease free interval seem to be independent prognostic factors identifying a cohort of patients maximally benefitting from lung metastasectomy.

Abstract
Surgery remains the mainstay of treatment for colon and rectal cancers. Colon cancer outcomes have improved with laparoscopic techniques, enhanced recovery pathways, and adjuvant chemotherapy. Adjuvant 5-fluorouracil with or without oxaliplatin in stage III and possibly high-risk stage II colon cancer is associated with improved survival. Multimodality management of rectal cancer continues to evolve; total mesorectal excision is the cornerstone. Oncologic results do not support the use of laparoscopic resection in rectal cancer. Preoperative short- or long-course radiation for stage II or III rectal cancer is the standard of care. Long course chemoradiation is recommended for bulky tumors.

Abstract
Importance Primary care clinicians, who are increasingly responsible for caring for the growing population of cancer survivors, may be unfamiliar with appropriate cancer surveillance strategies. Clinical practice guidelines can inform cancer follow-up care and surveillance testing. Vague recommendations and inconsistencies among guidelines can lead to overuse and underuse of health care resources and have a negative impact on cost and quality of survivorship care. Objective To examine the specificity and consistency of recommendations for surveillance after active treatment across cancer guidelines. Design, Setting, and Participants Retrospective cross-sectional analysis of national cancer guidelines from North America and Europe published since 2010 addressing posttreatment care for survivors of the 9 most common cancers. We categorized surveillance modalities into history and physical examinations, tumor markers, diagnostic procedures (eg, colonoscopy), and imaging. Within each guideline, we classified individual recommendations into 5 categories: (1) risk-based recommendation, (2) recommendation for surveillance, (3) addressed but no clear recommendation, (4) recommendation against surveillance, or (5) cases in which surveillance was not addressed. We reviewed each surveillance recommendation for frequency and a stop date, evaluated consistency among guidelines, and analyzed associations between the organizations proposing the guidelines and recommendation characteristics. Main Outcomes and Measures Description of guideline recommendations for cancer surveillance. Results We identified 41 guidelines published between January 1, 2010, and March 1, 2016. Eighty-five percent of guidelines (35) were from professional organizations. Ambiguous recommendations (ie, modality not discussed or discussed without a clear recommendation) were present in 83% of guidelines (34), and 44% (18) recommended against at least 1 test. European guidelines were more likely than North American guidelines to contain ambiguous recommendations (100% vs 68%; P < .01). Recommendations commonly specified testing frequency (from 88% [14 of 16] for tumor markers to 92% [24 of 26] for procedures and/or imaging) but infrequently provided a definitive stop time. Cross-sectional imaging recommendations varied among guidelines for each cancer. For example, among breast cancer guidelines, surveillance computed tomographic scans were recommended against in 2, discussed without a clear recommendation in 1, and not addressed in 3 guidelines. Conclusions and Relevance Guidelines addressing the care of cancer survivors have low specificity and consistency. As guidelines continue to be revised, developers should clarify recommendations with simple, nonambiguous, definitive language for or against the use of specific tests to optimize care quality and resource utilization.

Abstract
BACKGROUND Intensive follow-up after surgery for colorectal cancer is common practice but lacks a firm evidence base. OBJECTIVE To assess whether or not augmenting symptomatic follow-up in primary care with two intensive methods of follow-up [monitoring of blood carcinoembryonic antigen (CEA) levels and scheduled imaging] is effective and cost-effective in detecting the recurrence of colorectal cancer treatable surgically with curative intent. DESIGN Randomised controlled open-label trial. Participants were randomly assigned to one of four groups: (1) minimum follow-up (n = 301), (2) CEA testing only (n = 300), (3) computerised tomography (CT) only (n = 299) or (4) CEA testing and CT (n = 302). Blood CEA was measured every 3 months for 2 years and then every 6 months for 3 years; CT scans of the chest, abdomen and pelvis were performed every 6 months for 2 years and then annually for 3 years. Those in the minimum and CEA testing-only arms had a single CT scan at 12-18 months. The groups were minimised on adjuvant chemotherapy, gender and age group (three strata). SETTING Thirty-nine NHS hospitals in England with access to high-volume services offering surgical treatment of metastatic recurrence. PARTICIPANTS A total of 1202 participants who had undergone curative treatment for Dukes' stage A to C colorectal cancer with no residual disease. Adjuvant treatment was completed if indicated. There was no evidence of metastatic disease on axial imaging and the post-operative blood CEA level was ≤ 10 µg/l. MAIN OUTCOME MEASURES Primary outcome Surgical treatment of recurrence with curative intent. Secondary outcomes Time to detection of recurrence, survival after treatment of recurrence, overall survival and quality-adjusted life-years (QALYs) gained. RESULTS Detection of recurrence During 5 years of scheduled follow-up, cancer recurrence was detected in 203 (16.9%) participants. The proportion of participants with recurrence surgically treated with curative intent was 6.3% (76/1202), with little difference according to Dukes' staging (stage A, 5.1%; stage B, 7.4%; stage C, 5.6%; p = 0.56). The proportion was two to three times higher in each of the three more intensive arms (7.5% overall) than in the minimum follow-up arm (2.7%) (difference 4.8%; p = 0.003). Surgical treatment of recurrence with curative intent was 2.7% (8/301) in the minimum follow-up group, 6.3% (19/300) in the CEA testing group, 9.4% (28/299) in the CT group and 7.0% (21/302) in the CEA testing and CT group. Surgical treatment of recurrence with curative intent was two to three times higher in each of the three more intensive follow-up groups than in the minimum follow-up group; adjusted odds ratios (ORs) compared with minimum follow-up were as follows: CEA testing group, OR 2.40, 95% confidence interval (CI) 1.02 to 5.65; CT group, OR 3.69, 95% CI 1.63 to 8.38; and CEA testing and CT group, OR 2.78, 95% CI 1.19 to 6.49. Survival A Kaplan-Meier survival analysis confirmed no significant difference between arms (log-rank p = 0.45). The baseline-adjusted Cox proportional hazards ratio comparing the minimum and intensive arms was 0.87 (95% CI 0.67 to 1.15). These CIs suggest a maximum survival benefit from intensive follow-up of 3.8%. Cost-effectiveness The incremental cost per patient treated surgically with curative intent compared with minimum follow-up was £40,131 with CEA testing, £43,392 with CT and £85,151 with CEA testing and CT. The lack of differential impact on survival resulted in little difference in QALYs saved between arms. The additional cost per QALY gained of moving from minimum follow-up to CEA testing was £25,951 and for CT was £246,107. When compared with minimum follow-up, combined CEA testing and CT was more costly and generated fewer QALYs, resulting in a negative incremental cost-effectiveness ratio (-£208,347) and a dominated policy. LIMITATIONS Although this is the largest trial undertaken at the time of writing, it has insufficient power to assess whether or not the improvement in detecting treatable recurrence achieved by intensive follow-up leads to a reduction in overall mortality. CONCLUSIONS Rigorous staging to detect residual disease is important before embarking on follow-up. The benefit of intensive follow-up in detecting surgically treatable recurrence is independent of stage. The survival benefit from intensive follow-up is unlikely to exceed 4% in absolute terms and harm cannot be absolutely excluded. A longer time horizon is required to ascertain whether or not intensive follow-up is an efficient use of scarce health-care resources. Translational analyses are under way, utilising tumour tissue collected from Follow-up After Colorectal Surgery trial participants, with the aim of identifying potentially prognostic biomarkers that may guide follow-up in the future.

Br J Surg 2017; 104:1069-1077. [PMID: 28376235 DOI: 10.1002/bjs.10535] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2016] [Revised: 11/30/2016] [Accepted: 02/08/2017] [Indexed: 01/09/2023]
Abstract
BACKGROUND The CEAwatch randomized trial showed that follow-up with intensive carcinoembryonic antigen (CEA) monitoring (CEAwatch protocol) was better than care as usual (CAU) for early postoperative detection of colorectal cancer recurrence. The aim of this study was to calculate overall survival (OS) and disease-specific survival (DSS). METHODS For all patients with recurrence, OS and DSS were compared between patients detected by the CEAwatch protocol versus CAU, and by the method of detection of recurrence, using Cox regression models. RESULTS Some 238 patients with recurrence were analysed (7·5 per cent); a total of 108 recurrences were detected by CEA blood test, 64 (55·2 per cent) within the CEAwatch protocol and 44 (41·9 per cent) in the CAU group (P = 0·007). Only 16 recurrences (13·8 per cent) were detected by patient self-report in the CEAwatch group, compared with 33 (31·4 per cent) in the CAU group. There was no significant improvement in either OS or DSS with the CEAwatch protocol compared with CAU: hazard ratio 0·73 (95 per cent 0·46 to 1·17) and 0·78 (0·48 to 1·28) respectively. There were no differences in survival when recurrence was detected by CT versus CEA measurement, but both of these methods yielded better survival outcomes than detection by patient self-report. CONCLUSION There was no direct survival benefit in favour of the intensive programme, but the CEAwatch protocol led to a higher proportion of recurrences being detected by CEA-based blood test and reduced the number detected by patient self-report. This is important because detection of recurrence by blood test was associated with significantly better survival than patient self-report, indirectly supporting use of the CEAwatch protocol.

Abstract
PURPOSE To clarify experiences and preferences of patients regarding the current and future role of GPs during treatment and follow-up care of colorectal cancer (CRC). METHODS Qualitative semi-structured, audio-recorded, face-to-face interviews in patients' homes in the north of the Netherlands were performed. Patients were sampled purposively on age, gender, time since diagnoses and primary health care use. Data were transcribed verbatim and analysed thematically by two independent researchers until saturation was reached. RESULTS Twenty-two patients were interviewed. GPs played a significant and highly valued role directly after surgery by proactively contacting their patients and offered support in clarification of medical issues, lifestyle advice and care for treatment-related side effects. During follow-up, GPs provided psychosocial support for patients and family members, besides routine health care. Concerning the organization of future follow-up care, most patients expressed a preference for specialist-led services; some said that primary care-led care would be more accessible and less expensive. CONCLUSION Although at present patients perceived their GP is involved in CRC care, they would prefer their follow-up care in a hospital setting. If, in line with recent insights, future follow-up care might become more relying on testing for markers instead of imaging, there may be scope for incorporating this care in current GP routines.

Abstract
BACKGROUND There is no evidence from randomized trials on the prognostic significance of pulmonary metastasectomy of colorectal cancer. The objective of this study was to assess the current criteria for indications, preoperative diagnostics and preferred operative techniques of pulmonary metastasectomy in Germany. METHODS An anonymous survey was carried out in 239 German centers performing thoracic surgery in October 2015. RESULTS Chest computed tomography (CT, 98%), liver CT (62%), pelvis CT (39%) and fluorodeoxyglucose positron emission tomography (FDG-PET, 37%) were used by the respondents (65% of participants) for preoperative staging. Pulmonary metastasectomy was most commonly performed for solitary lung metastasis without extrathoracic disease (96%), >1 ipsilateral lung metastases without extrathoracic disease (94.8%), solitary lung metastasis with resectable hepatic metastases (92%) and resectable bilateral lung metastases without extrathoracic disease (91%). Of the respondents 95% performed open lung metastasectomy, 82% video-assisted thoracic surgery, 18% radiofrequency ablation, 53% used laser-assisted open resection and 46% indicated that there was no scientific consensus on pulmonary metastasectomy. CONCLUSION The majority of respondents performed pulmonary metastasectomy for solitary and multiple, unilateral and bilateral lung metastases without extrathoracic disease and/or local recurrence of primary tumors. The coexistence of resectable liver metastases was not an absolute contraindication for surgery. Of the respondents 46% expressed the need for prospective randomized studies to improve the evidence on pulmonary metastasectomy for colorectal cancer.

Abstract
BACKGROUND It is common clinical practice to follow patients with colorectal cancer (CRC) for several years following their curative surgery or adjuvant therapy, or both. Despite this widespread practice, there is considerable controversy about how often patients should be seen, what tests should be performed, and whether these varying strategies have any significant impact on patient outcomes. This is the second update of a Cochrane Review first published in 2002 and first updated in 2007. OBJECTIVES To assess the effects of intensive follow-up for patients with non-metastatic colorectal cancer treated with curative intent. SEARCH METHODS For this update, we searched CENTRAL (2016, Issue 3), MEDLINE (1950 to May 20th, 2016), Embase (1974 to May 20th, 2016), CINAHL (1981 to May 20th, 2016), and Science Citation Index (1900 to May 20th, 2016). We also searched reference lists of articles, and handsearched the Proceedings of the American Society for Radiation Oncology (2011 to 2014). In addition, we searched the following trials registries (May 20th, 2016): ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. We further contacted study authors. No language or publication restrictions were applied to the search strategies. SELECTION CRITERIA We included only randomised controlled trials comparing different follow-up strategies for participants with non-metastatic CRC treated with curative intent. DATA COLLECTION AND ANALYSIS Two authors independently determined trial eligibility, performed data extraction, and assessed methodological quality. MAIN RESULTS We studied 5403 participants enrolled in 15 studies. (We included two new studies in this second update.) Although the studies varied in setting (general practitioner (GP)-led, nurse-led, or surgeon-led) and "intensity" of follow-up, there was very little inconsistency in the results.Overall survival: we found no evidence of a statistical effect with intensive follow-up (hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.78 to 1.02; I² = 4%; P = 0.41; high-quality evidence). There were 1098 deaths among 4786 participants enrolled in 12 studies.Colorectal cancer-specific survival: this did not differ with intensive follow-up (HR 0.93, 95% CI 0.78 to 1.12; I² = 0%; P = 0.45; moderate-quality evidence). There were 432 colorectal cancer deaths among 3769 participants enrolled in seven studies.Relapse-free survival: we found no statistical evidence of effect with intensive follow-up (HR 1.03, 95% CI 0.90 to 1.18; I² = 5%; P = 0.39; moderate-quality evidence). There were 1416 relapses among 5253 participants enrolled in 14 studies.Salvage surgery with curative intent: this was more frequent with intensive follow-up (risk ratio (RR) 1.98, 95% CI 1.53 to 2.56; I² = 31%; P = 0.14; high-quality evidence). There were 457 episodes of salvage surgery in 5157 participants enrolled in 13 studies.Interval (symptomatic) recurrences: these were less frequent with intensive follow-up (RR 0.59, 95% CI 0.41 to 0.86; I² = 66%; P = 0.007; moderate-quality evidence). Three hundred and seventy-six interval recurrences were reported in 3933 participants enrolled in seven studies.Intensive follow-up did not appear to affect quality of life, anxiety, nor depression (reported in three studies).Harms from colonoscopies did not differ with intensive follow-up (RR 2.08, 95% CI 0.11 to 40.17; moderate-quality evidence). In two studies, there were seven colonoscopic complications in 2112 colonoscopies. AUTHORS' CONCLUSIONS The results of our review suggest that there is no overall survival benefit for intensifying the follow-up of patients after curative surgery for colorectal cancer. Although more participants were treated with salvage surgery with curative intent in the intensive follow-up group, this was not associated with improved survival. Harms related to intensive follow-up and salvage therapy were not well reported.

Abstract
Background After potentially curative resection of primary colorectal cancer, patients may be monitored by measurement of carcinoembryonic antigen and/or CT to detect asymptomatic metastatic disease earlier. Methods A systematic review and meta-analysis was conducted to find evidence for the clinical effectiveness of monitoring in advancing the diagnosis of recurrence and its effect on survival. MEDLINE (Ovid), Embase, the Cochrane Library, Web of Science and other databases were searched for randomized comparisons of increased intensity monitoring compared with a contemporary standard policy after resection of primary colorectal cancer. Results There were 16 randomized comparisons, 11 with published survival data. More intensive monitoring advanced the diagnosis of recurrence by a median of 10 (i.q.r. 5–24) months. In ten of 11 studies the authors reported no demonstrable difference in overall survival. Seven RCTs, published from 1995 to 2016, randomly assigned 3325 patients to a monitoring protocol made more intensive by introducing new methods or increasing the frequency of existing follow-up protocols versus less invasive monitoring. No detectable difference in overall survival was associated with more intensive monitoring protocols (hazard ratio 0·98, 95 per cent c.i. 0·87 to 1·11). Conclusion Based on pooled data from randomized trials published from 1995 to 2016, the anticipated survival benefit from surgical treatment resulting from earlier detection of metastases has not been achieved.
