Abstract
OBJECTIVE To examine healthcare utilisation and adherence to colorectal cancer (CRC) follow-up guidelines. METHODS A total of 2450 out of 3025 stage I-III CRC survivors diagnosed between 2000 and 2009 completed the Hospital Anxiety and Depression Scale, SF-12, EORTC QLQ-CR38 and Fatigue Assessment Score questionnaires, in December 2010. Multivariable regression analyses were performed to identify predictors for increased follow-up care (>1 visit than recommended by guidelines). RESULTS In the first follow-up year, the average number of cancer-related visits to the general practitioner and medical specialist was 1.7 and 4.2, respectively. More than 80% of the CRC survivors was comfortable with their follow-up schedule, and 49-72% of them received follow-up according to the guidelines. Around 29-47% was followed more than recommended. Simultaneously, around 4-14% of the CRC survivors received less follow-up care than recommended. Survivors of stage III disease treated with chemotherapy received the most follow-up care. In addition, lower socio-economic status stoma and fatigue were associated with increased follow-up care. CONCLUSION CRC survivors were predominantly followed according to national guidelines. Increased follow-up care is driven by advanced disease stage, chemotherapy, SES, stoma and fatigue. Future studies should investigate how increased follow-up care use can be reduced, while still addressing patients' needs.

Abstract
Purpose Patients with peritoneal carcinomatosis (PC) are increasingly treated with multidisciplinary combined approaches. The study aim was to assess current practice and perceptions of treatment modalities of PC. Methods Indian Society of Peritoneal Surface Malignancies (ISPSM) members were invited to complete an online survey. Current practice and perceptions of treatment modalities were assessed through 19 closed questions. Scores were assessed using a Likert scale (0: not important, 5: very important). Treatment modality satisfaction was assessed using a semantic scale (frustrated: 0, perfectly happy: 10). Participants were sent 3 reminders at 4-week intervals. Results Fifty-seven out of 182 members completed the survey (31%). Forty percent of participants had an experience of at least 10 years, and 75% stated treating less than 20 PC patients per year. Main treatment goals for patients with PC were cure (5/5) and symptom relief (4/5). Participant’s satisfaction with treatment modalities for ovarian, colorectal, and gastric PC were 6/10, 5/10, and 2/10, respectively. Hyperthermic intraperitoneal chemotherapy (HIPEC) for ovarian (57%) and colorectal (44%) origins were considered to be useful. Clinical usefulness of chemotherapy for gastric PC was rated to be low (17%). Conclusions Current treatment modalities fall short to satisfy the needs (cure, symptom relief) of patients with PC. Alternative systemic and intraperitoneal treatment modalities should be assessed.

Abstract
BACKGROUND The precise content and frequency of follow-up of patients with colorectal cancer (CRC) is variable and guideline adherence is low. The aim of this study was to assess the view of colorectal surgeons on their local follow-up schedule and to clarify their opinions about risk-stratification and organ preserving therapies. Equally important, adherence to the Dutch national guidelines was determined. METHODS Colorectal surgeons were invited to complete a web-based survey about the importance and interval of clinical follow-up, CEA monitoring and the use of imaging modalities. Furthermore, the opinions regarding physical examination, risk-stratification, organ preserving strategies, and follow-up setting were assessed. Data were analyzed using quantitative and qualitative analysis methods. RESULTS A total of 106 colorectal surgeons from 52 general and 5 university hospitals filled in the survey, yielding a hospital response rate of 74% and a surgeon response rate of 42%. The follow-up of patients with CRC was mainly done by surgeons (71%). The majority of the respondents (68%) did not routinely perform physical examination during follow-up of rectal patients. Abdominal ultrasound was the predominant modality used for detection of liver metastases (77%). Chest X-ray was the main modality for detecting lung metastases (69%). During the first year of follow-up, adherence to the minimal guideline recommendations was high (99-100%). The results demonstrate that, within the framework of the guidelines, some respondents applied a more intensive follow-up and others a less intensive schedule. The majority of the respondents (77%) applied one single follow-up imaging schedule for all patients that underwent treatment with curative intent. CONCLUSIONS Dutch colorectal surgeons' adherence to minimal guideline recommendations was high, but within the guideline framework, opinions differed about the required intensity and content of clinical visits, the interval of CEA monitoring, and the importance and frequency of imaging techniques. This national survey demonstrates current follow-up practice throughout the Netherlands and highlights the follow-up differences of curatively treated patients with CRC.

Abstract
Previously, we reported a combination of an urine collagen alpha-1(I) natural occurring peptide (NOP) AGPP(-OH)GEAGKP(-OH)GEQGVP(-OH)GDLGAP(-OH)GP (AGP) and serum carcinoembryonic antigen (CEA) to have the potential to detect colorectal liver metastasis (CRLM). The combined method requires further adaption for better sensitivity and specificity prior to clinical implementation. This mass spectrometry study aimed to identify additional collagen NOPs in urine and determine the most discriminating NOP panel. We improved the combined method on the basis of analysis of urine samples from 100 healthy controls and 100 CRLM patients. Two additional NOPs were identified: GPPGEAGK(-OH)P(-OH)GEQGVP(-OH)GDLGAP(-OH)GP (GPP), collagen alpha-1(I), and GNDGARGSDGQPGPP(-OH)GP(-OH)P(-OH)GTAGFP(-OH)GSP(-OH)GAK(-OH)GEVGP (GND), collagen alpha-1(III). A molecular model combining NOPs (AGP, GPP, and GND) and CEA was generated. Molecules that did not contribute significantly were removed, resulting in a model consisting of GND and CEA. With this model, 88% sensitivity and 88% specificity were reached in the discovery set and 75% sensitivity and 100% specificity in the validation set (control, n = 12; CRLM, n = 10). The AUC of the ROC curve is significantly higher than the current model based on AGP and CEA (p = 3.3 × 10-4). The new model performs better than the currently used techniques in the clinic that have a 57-70% sensitivity and a 90-96% specificity.

Abstract
INTRODUCTION The completeness of the pathological examination of resected colon cancer specimens is important for further clinical management. We reviewed the pathological reports of 356 patients regarding the five factors (pT-stage, tumor differentiation grade, lymphovascular invasion, tumor perforation and lymph node metastasis status) that are used to identify high-risk stage II colon cancers, as well as their impact on overall survival (OS). METHODS All patients with stage II colon cancer who were included in the first five years of the MATCH study (1 July 2007 to 1 July 2012) were selected (n = 356). The hazard ratios of relevant risk factors were calculated using Cox Proportional Hazards analyses. RESULTS In as many as 69.1% of the pathology reports, the desired information on one or more risk factors was considered incomplete. In multivariable analysis, age (HR: 1.07, 95%CI 1.04-1.10, p < .001), moderately- (HR: 0.35, 95%CI 0.18-0.70, p = .003) and well (HR 0.11, 95%CI 0.01-0.89, p = .038) differentiated tumors were significantly associated with OS. CONCLUSIONS Pathology reports should better describe the five high-risk factors, in order to enable proper patient selection for further treatment. Chemotherapy may be offered to stage II patients only in select instances, yet a definitive indication is still unavailable.

Br J Surg 2017; 104:1069-1077.

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.

Intensified follow-up in colorectal cancer patients using frequent Carcino-Embryonic Antigen (CEA) measurements and CEA-triggered imaging: Results of the randomized "CEAwatch" trial. Eur J Surg Oncol 2015; 41:1188-96.

Abstract
AIM The value of frequent Carcino-Embryonic Antigen (CEA) measurements and CEA-triggered imaging for detecting recurrent disease in colorectal cancer (CRC) patients was investigated in search for an evidence-based follow-up protocol. METHODS This is a randomized-controlled multicenter prospective study using a stepped-wedge cluster design. From October 2010 to October 2012, surgically treated non-metastasized CRC patients in follow-up were followed in eleven hospitals. Clusters of hospitals sequentially changed their usual follow-up care into an intensified follow-up schedule consisting of CEA measurements every two months, with imaging in case of two CEA rises. The primary outcome measures were the proportion of recurrences that could be treated with curative intent, recurrences with definitive curative treatment outcome, and the time to detection of recurrent disease. RESULTS 3223 patients were included; 243 recurrences were detected (7.5%). A higher proportion of recurrences was detected in the intervention protocol compared to the control protocol (OR = 1.80; 95%-CI: 1.33-2.50; p = 0.0004). The proportion of recurrences that could be treated with curative intent was higher in the intervention protocol (OR = 2.84; 95%-CI: 1.38-5.86; p = 0.0048) and the proportion of recurrences with definitive curative treatment outcome was also higher (OR = 3.12, 95%-CI: 1.25-6.02, p-value: 0.0145). The time to detection of recurrent disease was significantly shorter in the intensified follow-up protocol (HR = 1.45; 95%-CI: 1.08-1.95; p = 0.013). CONCLUSION The CEAwatch protocol detects recurrent disease after colorectal cancer earlier, in a phase that a significantly higher proportion of recurrences can be treated with curative intent.

Abstract
AIM With the increase in the number of long-term colorectal cancer (CRC) survivors, there is a growing need for subgroup-specific analysis of conditional survival. METHODS All 137,030 stage I-III CRC patients diagnosed in the Netherlands between 1989 and 2008 aged 15-89 years were selected from the Netherlands Cancer Registry. We determined conditional 5-year relative survival rates, according to age, subsite and tumour stage for each additional year survived up to 15 years after diagnosis as well as trends in absolute risks for and distribution of causes of death during follow-up. RESULTS Minimal excess mortality (conditional 5-year relative survival >95%) was observed 1 year after diagnosis for stage I colon cancer patients, while for rectal cancer patients this was seen after 6 years. For stage II and III CRC, minimal excess mortality was seen 7 years after diagnosis for colon cancer, while for rectal cancer this was 12years. The differences in conditional 5-year relative survival between colon and rectal cancer diminished over time for all patients, except for stage III patients aged 60-89 years. The absolute risk to die from CRC diminished sharply over time and was below 5% after 5 years. The proportion of patients dying from CRC decreased over time after diagnosis while the proportions of patients dying from other cancers, cardiovascular disease and other causes increased. CONCLUSION Prognosis for CRC survivors improved with each additional year survived, with the largest improvements in the first years after diagnosis. Quantitative insight into conditional relative survival estimates is useful for caregivers to inform and counsel patients with stage I-III colon and rectal cancer during follow-up.

Abstract
PURPOSE The aims of the study were to describe the follow-up of colorectal cancer (CRC) patients in southern Netherlands and examine their overall and disease-free survival. METHODS Patients newly diagnosed with CRC in 2003-2005 and 2008 with a survival of at least 1 year after diagnosis and recorded in the retrospective Eindhoven Cancer Registry were included (n = 579). Follow-up was defined as at least one liver imaging and at least two carcinoembryonic antigen (CEA) measurements. Logistic regression analyses were conducted to assess determinants of follow-up. Proportions of patients undergoing colonoscopy, CEA measurements and liver and chest imaging were calculated. Overall and disease-free survival were calculated. RESULTS Patients ≥75 years (odds ratio (OR) 0.5 (95% confidence interval (CI) 0.3-0.7)) were less likely to receive follow-up, contrasting patients <50 years (OR 3.1 (95% CI 1.3-7.4)). In 2008, follow-up intensity increased (OR 2.3 (95% CI 1.2-4.3)), especially for liver imaging and CEA measurements. There were large differences in follow-up intensity and activities between hospitals, which were unaffected by comorbidity: ranges for colonoscopy 15-73 %, CEA measurement 46-91 % and imaging of the liver 22-70 % between hospitals. No effect of follow-up intensity was found on 5-year disease-free survival for patients aged <75 years (64 vs. 68 %; p = 0.6). Similarly, no effect of follow-up intensity on 5-year overall survival was found in these patients (77 vs. 82 %; p = 0.07). CONCLUSION Large variation in follow-up was found for patients with CRC, mainly declining with age and hospital of follow-up. Over time, follow-up became more intensive, especially with respect to liver imaging and CEA measurements. However, follow-up consisting of at least one liver imaging and at least two CEA measurements did not improve overall and disease-free survival.

Abstract
Early diagnosis of recurrence and metastasis of colorectal cancer following surgery of curative intent is of vital importance in terms of survival and quality of life. The consistent implementation of appropriate patient follow-up strategy is therefore essential. Debates over the methodology, evaluation and strategy of follow-up have been known for many years, and continue today. By introducing several follow-up models, the present paper offers different options featuring certain individual, national and international, conceptual and financial aspects. Colorectal cancer is an important public health concern due to its destructive nature and frequency, it is therefore essential to develop new monitoring strategies, involving new biomarkers and extensive clinical validation. Since the recurrence rate is very high in high-risk patients, the improvement of individual patient risk estimates and the utilization of a corresponding follow-up model require broad international co-operation and common practice, along with the determination of optimal levels of evidence.

Abstract
AIM Complete surgical resection is considered the best treatment for recurrent rectal cancer (RRC). The aim of the study was to compare survival outcomes from operative and nonoperative patients presenting with RRC. METHOD Patients with RRC whose management was discussed by a tertiary referral specialist multidisciplinary team between January 2007 and August 2011 were identified from a prospectively maintained database. The primary end-point was 3-year overall survival. RESULTS Of 127 patients with RRC, it was isolated to the pelvis in 105 and associated with distant disease at presentation in 22. From the time of primary surgery to first recurrence, 1-, 3-, 5- and 10-year local recurrence rates were 22%, 72%, 85% and 96%, respectively. The number of operated patients available at 1, 2 and 3 years' follow-up was 53, 34 and 23, respectively. Of 70 patients who underwent pelvic resection for recurrence, 64% received R0, 20% received R1 and 16% received R2 resections. Corresponding 3-year overall survival rates were 69%, 56% and 20% (P=0.011). There was no significant difference in survival between R2 resection and those managed nonoperatively (hazard ratio=1.258; P=0.579). Those undergoing surgery for pelvic recurrence affecting one or more compartments had a worse prognosis than those with single-compartment involvement (hazard ratio=2.640; P=0.027). Three-year local recurrence-free survival was 80% with R0 resection vs 60% with R1 resection. CONCLUSION Most recurrences occur within 5 years of primary surgery, although some occur up to 10 years later. R0 resection is the treatment of choice. There was no survival benefit of R2 resection over nonresected recurrences.

Abstract
Background Serum carcinoembryonic antigen (CEA) levels are not universally measured in colorectal cancers. CEA levels have been reported to be usually normal at time of primary rectal cancer diagnosis but elevated in recurrent disease. The aims of the study were to (1) compare serum CEA levels performed at time of primary and recurrent colorectal tumour diagnosis; and (2) to determine serum CEA levels in rectal cancers at primary diagnosis to analyse potential factors influencing differing CEA levels. Methods A retrospective analysis of patients treated for colorectal cancers at Modbury Hospital, South Australia was performed. Each admission was reviewed within the electronic database. Serum CEA levels and tumour-related factors were determined in patients who underwent curative surgery for their primary tumour and developed tumour recurrence/metastases within the study period. Results 438 patients were treated for colorectal cancer in the study period. In patients who underwent curative surgery and developed a recurrence, serum CEA was elevated in 20% patients at primary diagnosis and in 46.6% patients at recurrence. Only 1 of 30 patients with rectal cancer had an elevated CEA at diagnosis of primary tumour. Tumour relationship to the peritoneal reflection did not appear to play a role. Conclusions In rectal cancers, serum CEA levels are often normal at the time of initial diagnosis. However, this should not preclude its use in post-operative surveillance. Serum CEA levels noted in primary rectal cancer appear unrelated to the relationship of the tumour to the peritoneal reflection. Stroma-related factors could possibly be involved and merit further investigation.

Abstract
Background The present paper is a first evaluation of the use of "CEAwatch", a clinical support software system for surgeons for the follow-up of colorectal cancer (CRC) patients. This system gathers Carcino-Embryonic Antigen (CEA) values and automatically returns a recommendation based on the latest values. Methods Consecutive patients receiving follow-up care for CRC fulfilling our in- and exclusion criteria were identified to participate in this study. From August 2008, when the software was introduced, patients were asked to undergo the software-supported follow-up. Safety of the follow-up, experiences of working with the software, and technical issues were analyzed. Results 245 patients were identified. The software-supported group contained 184 patients; the control group contained 61 patients. The software was safe in finding the same amount of recurrent disease with fewer outpatient visits, and revealed few technical problems. Clinicians experienced a decrease in follow-up workload of up to 50% with high adherence to the follow-up scheme. Conclusion CEAwatch is an efficient software tool helping clinicians working with large numbers of follow-up patients. The number of outpatient visits can safely be reduced, thus significantly decreasing workload for clinicians.

Abstract
AIM National guidelines recommend enrollment of patients in surveillance programmes following curative resection of colorectal carcinoma (CRC) in order to detect recurrence or distant metastasis at an asymptomatic/early stage when secondary curative treatment can be offered. Little is known about surgeons' adherence to such guidelines. In this national survey we analyse adherence and attitudes to postoperative follow up among Norwegian gastrointestinal surgeons involved in the care of patients with CRC. METHOD We performed a nationwide survey of all hospitals performing surgery for colon and/or rectum cancer. The presence of a surveillance programme, the type of programme, adherence to national guidelines or report on any deviation thereof, location of follow up at the hospital or with a general practitioner (GPs) and the estimated annual volume of surgery were queried through mail and telephone. RESULTS All hospitals (n=41) performing colorectal surgery responded, of which 25 (61%) conducted postoperative follow up by surgeons in the hospital outpatient clinics, four (10%) carried out follow up with a combination of hospital outpatient visits and visits to GPs, and 12 (29%) referred surveillance to the GP alone. For total reported patient numbers, almost two-thirds (60%) received surveillance according to national recommendations through outpatient visits with the surgeon or GP, while one-third (37%) were subject to other alternative routines. A small number (2%) received informal 'ad hoc' surveillance only. More liberal use of imaging outside guideline recommendations was reported for rectal cancer patients, while colon cancer patients treated in larger hospitals were more likely to be referred for GP surveillance. CONCLUSION All hospitals reported having a strategy for surveillance after surgery for colon and rectal cancer, but there was considerable variance in strategy. A scientific audit of the true level of compliance, effectiveness and cost-benefit is warranted at a national level.

Abstract
PURPOSE Intensive surveillance after curative treatment of colorectal cancer (CRC) is associated with improved overall survival. This study examined concordance with the 2005 ASCO surveillance guidelines at the population level. METHODS A cohort of 250 patients diagnosed with stage II or III CRC in 2004 and alive 42 months after diagnosis was identified from health administrative data in Manitoba, Canada. Colonoscopy, liver imaging, and carcinoembryonic antigen (CEA) testing were assessed over 3 years. Guidelines were met if patients had at least one colonoscopy in 3 years and at least one liver imaging test and three CEA tests annually. Multivariate logistic regression assessed the effect of patient and physician characteristics and disease and treatment factors on guideline concordance. RESULTS Guidelines for colonoscopy, liver imaging, and CEA were met by 80.4%, 47.2%, and 22% of patients, respectively. Guideline concordance for colonoscopy was predicted by annual contact with a surgeon, higher income, and the diagnosis of colon (rather than rectal) cancer. Adherence was lower in those older than 70 years and with higher comorbidity. For liver imaging, significant predictors were annual contact with an oncologist, receipt of chemotherapy, and diagnosis of colon cancer. Concordance with CEA guidelines was higher with annual contact with an oncologist and high levels of family physician contact, and lower in urban residents, in those older than 70, and in those with stage II disease. CONCLUSION Completion of recommended liver imaging and CEA testing fall well below guidelines in Manitoba, whereas colonoscopy is better provided. Addressing this gap should improve outcomes for CRC survivors.

Abstract
Surgical resection is the primary treatment modality for patients with localized colorectal cancer, but unfortunately one-third to one-half of these patients will develop a recurrence. If detected early, recurrent disease may be amenable to surgical resection and this provides the rationale for a follow-up strategy in patients with resected colorectal cancer. Despite eight published randomized controlled trials and six published systematic reviews evaluating different follow-up strategies, there is still no consensus as to the appropriateness of follow-up in colorectal cancer patients. In the present article the authors explore the reasons behind the controversy and the arguments used to support each side. They outline the current published guidelines and the data to support these recommendations, including the use of carcinoembryonic antigen (CEA) levels, liver imaging, and colonoscopy. Finally, they speculate on the future developments that may impact on this debate.

The Role of High Frequency Dynamic Threshold (HiDT) Serum Carcinoembryonic Antigen (CEA) Measurements in Colorectal Cancer Surveillance: A (Revisited) Hypothesis Paper. Cancers (Basel) 2011; 3:2302-15.

Abstract
Following curative treatment for colorectal cancer (CRC), 30% to 50% of patients will develop recurrent disease. For CRC there are several lines of evidence supporting the hypothesis that early detection of metachronous disease offers a second opportunity for cure. This paper revisits the potential role of serum carcinoembryonic antigen (CEA) in follow-up. A comprehensive review of the literature (1978–2008) demonstrates that the initial promise of serum CEA as an effective surveillance tool has been tarnished through perpetuation of poorly designed studies. Specific limitations included: testing CEA as only an ‘add-on’ diagnostic tool; lack of standardization of threshold values; use of static thresholds; too low measurement frequency. Major changes in localizing imaging techniques and treatment of metastatic CRC further cause a decrease of clinical applicability of past trial outcomes. In 1982, Staab hypothesized that the optimal benefit of serum CEA as a surveillance tool is through high-frequency triage using a dynamic threshold (HiDT). Evidence supporting this hypothesis was found in the biochemical characteristics of serum CEA and retrospective studies showing the superior predictive value of a dynamic threshold. A multi-centred randomized phase III study optimizing the usage of HiDT against resectability of recurrent disease is commencing recruitment in the Netherlands.

Abstract
AIM To provide insight into professionals' opinions on breast cancer follow-up to facilitate implementation of new follow-up strategies. The study focuses on current practice, purpose and perceived effects, and preferred frequency and duration of follow-up. DESIGN A 29-item questionnaire on professionals' demographics, current practice, opinion on the current guideline, preferences in frequency and duration of tailored follow-up, and the purpose and perceived effects of follow-up was sent to 633 Dutch professionals. RESULTS The current national guideline is followed by 81% of respondents. All different specialists are involved in follow-up. Sixty-nine percent of respondents' report nurse practitioners to be involved in follow-up. When asked for tailored follow-up, professionals indicate more factors for increased follow-up (age<40 years, pT3-4 tumour, pN2-3, treatment related morbidity, and psychosocial support), than for reduced schedules (age >70 years and DCIS histology). Alternative forms of follow-up are not endorsed by >90% of respondents. Detection of a new primary tumour of the breast is considered the most important purpose of follow-up (98%), 57% still indicates detecting metastases as a goal. CONCLUSIONS Professionals tend towards longer and more intensive follow-up than the current guideline for a large group of patients. Limitations and developments in follow-up need to be considered to facilitate alternative follow-up strategies.

Abstract
OBJECTIVE A national study conducted for the Spanish Association of Surgeons with the aim of analysing the surgical treatment of colorectal cancer (CRC) in Spain and to compare it with scientific literature. MATERIAL AND METHODS A multicentre, descriptive, prospective and longitudinal study of patients with CRC who were treated by elective surgery. A total of 50 hospitals in 15 Autonomous Regions took part, with 496 treated cases in 2008. A total of 88 variables were collected. RESULTS The median age was 72 years, increase in ASA III patients; correct preoperative studies, 4% with no staging in the rectum. There was a tendency not to use the colon cleansing or to do it only one day. The percentage of complications is within the ranges in the literature, with the exception of surgical wound infections (19%). Mean of resected lymph nodes: 13.2; 4.3% no mesorectal resection. Mechanical anastomosis: 80.8%, 65.9% of the operations performed by a colorectal surgeon. Preoperative radiotherapy in 43.5% of rectal cancers. Chemotherapy: 32.9%. Laparoscopy: 35.1% of cases, conversion rate 13.8%. Use of antibiotics: 37.1%, blood transfusion: 20.6% and parenteral nutrition: 26.5%. CONCLUSIONS Surgical treatment of CRC in Spain has a level of quality and peri-operative results similar to the rest of Europe. Compared to previous studies, it was observed that there were advances in preparation of the patient, preoperative studies, imaging techniques, and improvements in surgical techniques with adoption of mesorectal excision, appropriate lymphadenectomies and preservation of sphincters. There are areas for improvement, such as a reduction in surgical wound infections, increase use of protective stoma, appropriate use of antibiotics, parenteral nutrition or neoadjuvants and complete colonoscopies.

Abstract
BACKGROUND We evaluated the efficiency of CEA and CA19-9 as tools for diagnosing recurrence in the postoperative surveillance of colorectal cancer. MATERIALS AND METHODS A total of 227 patients who underwent curative resection for colorectal cancer between 1999 and 2003 at our hospital received complete follow-up according to the schedule determined prospectively. Using receiver operating characteristic (ROC) analysis, performance of postoperative values of CEA or CA19-9 for detecting recurrence was assessed. RESULTS The sensitivity (1.000) and specificity (0.978) of the postoperative values of CEA in the high preoperative CEA group were very high. Even in the normal preoperative CEA group, the area under the curve (AUC) of the ROC curve of CEA (0.740, 95% confidence interval [95% CI], 0.628-0.852) was significantly larger than 0.5 (P < 0.001). The postoperative values of CA19-9 showed high sensitivity (0.833) and specificity (0.900) in the high preoperative CA19-9 group, while the AUC of the ROC curve of the normal preoperative group was as small as 0.510 (95% CI, 0.376-0.644). In the high preoperative CA19-9 group, however, there was no significant difference between the AUC of CA19-9 (0.904, 95% CI, 0.786-1.000) and that of CEA (0.869, 95% CI, 0.744-0.994) (P = 0.334). CONCLUSIONS The measurement of CEA is an efficient way to detect recurrence. The efficiency of measuring CA19-9 for the purpose of detecting recurrence is low, especially in patients with a normal level of preoperative CA19-9. Even in patients with a high preoperative level of CA19-9, CEA might be able to fill the role of CA19-9.

Abstract
Little is known about costs related to the surveillance of patients that have undergone curative resection of colorectal cancer. The aim of this study was to calculate the observed surveillance costs for 385 patients followed-up over a 3-year period, to estimate surveillance costs if French guidelines are respected, and to identify the determinants related to surveillance costs to derive a global estimation for France, using a linear mixed model. The observed mean surveillance cost was <euro> 713. If French recommendations were strictly applied, the estimated mean cost would vary between <euro> 680 and <euro> 1,069 according to the frequency of abdominal ultrasound. The predicted determinants of cost were: age, recurrence, duration of surveillance since diagnosis, and adjuvant treatments. For France, the surveillance cost represented 4.4% of the cost of colorectal cancer management. The cost of surveillance should now be balanced with its effectiveness and compared with surveillance alternatives.
