Abstract
OBJECTIVE Despite lacking clinical data, the Dutch government is considering increasing the minimum annual surgical volume per center from twenty to fifty cytoreductive surgeries (CRS) for advanced-stage ovarian cancer (OC). This study aims to evaluate whether this increase is warranted. METHODS This population-based study included all CRS for FIGO-stage IIB-IVB OC registered in eighteen Dutch hospitals between 2019 and 2022. Short-term outcomes included result of CRS, length of stay, severe complications, 30-day mortality, time to adjuvant chemotherapy, and textbook outcome. Patients were stratified by annual volume: low-volume (nine hospitals, <25), medium-volume (four hospitals, 29-37), and high-volume (five hospitals, 54-84). Descriptive statistics and multilevel logistic regressions were used to assess the (case-mix adjusted) associations of surgical volume and outcomes. RESULTS A total of 1646 interval CRS (iCRS) and 789 primary CRS (pCRS) were included. No associations were found between surgical volume and different outcomes in the iCRS cohort. In the pCRS cohort, high-volume was associated with increased complete CRS rates (aOR 1.9, 95%-CI 1.2-3.1, p = 0.010). Furthermore, high-volume was associated with increased severe complication rates (aOR 2.3, 1.1-4.6, 95%-CI 1.3-4.2, p = 0.022) and prolonged length of stay (aOR 2.3, 95%-CI 1.3-4.2, p = 0.005). 30-day mortality, time to adjuvant chemotherapy, and textbook outcome were not associated with surgical volume in the pCRS cohort. Subgroup analyses (FIGO-stage IIIC-IVB) showed similar results. Various case-mix factors significantly impacted outcomes, warranting case-mix adjustment. CONCLUSIONS Our analyses do not support further centralization of iCRS for advanced-stage OC. High-volume was associated with higher complete pCRS, suggesting either a more accurate selection in these hospitals or a more aggressive approach. The higher completeness rates were at the expense of higher severe complications and prolonged admissions.

Abstract
Despite the improved survival rates of patients with advanced stage melanoma since the introduction of ICIs, many patients do not have (long-term) benefit from these treatments. There is evidence that the exposome, an accumulation of host-extrinsic factors including environmental influences, could impact ICI response. Recently, a survival benefit was observed in patients with BRAF wild-type melanoma living in Denmark who initiated immunotherapy in summer as compared to winter. As the Netherlands lies in close geographical proximity to Denmark and has comparable seasonal differences, a Dutch validation cohort was established using data from our nationwide melanoma registry. In this study, we did not observe a similar seasonal difference in overall survival and are therefore unable to confirm the Danish findings. Validation of either the Dutch or Danish findings in (combined) patient cohorts from other countries would be necessary to determine whether this host-extrinsic factor influences the response to ICI-treatment.

Abstract
BACKGROUND Diabetes mellitus forms a slow pandemic. Cardiovascular risk and quality of diabetes care are strongly associated. Quality indicators improve diabetes management and reduce mortality and costs. Various national diabetes registries render national quality indicators. We describe diabetes care indicators for Dutch children and adults with diabetes, and compare them with indicators established by registries worldwide. METHODS Indicator scores were derived from the Dutch Pediatric and Adult Registry of Diabetes Indicator sets of other national diabetes registries were collected and juxtaposed with global and continental initiatives for indicator sets. RESULTS This observational cohort study included 3738 patients representative of the Dutch diabetic outpatient population. The Dutch Pediatric and Adult Registry of Diabetes harbors ten quality indicators comprising treatment volumes, HbA1c control, foot examination, insulin pump therapy, and real-time continuous glucose monitoring. Worldwide, nine national registries record quality indicators, with great variety between registries. HbA1c control is recorded most frequently, and no indicator is reported among all registries. CONCLUSIONS Wide variety among quality indicators recorded by national diabetes registries hinders international comparison and interpretation of quality of diabetes care. The potential of quality evaluation will be greatly enhanced when diabetes care indicators are aligned in an international standard set with variation across countries taken into consideration.

Abstract
OBJECTIVE Textbook outcome (TO) is a composite outcome measure used in surgical oncology to compare hospital outcomes using multiple quality indicators. This study aimed to develop TO as an outcome measure to assess healthcare quality for patients undergoing cytoreductive surgery (CRS) for advanced-stage ovarian cancer. METHODS This population-based study included all CRS for FIGO IIIC-IVB primary ovarian cancer registered in the Netherlands between 2017 and 2020. The primary outcome was TO, defined as a complete CRS, combined with the absence of 30-day mortality, severe complications, and prolonged length of admission (≥ten days). Delayed start of adjuvant chemotherapy (≥six weeks) was not included in TO because of missing data. Logistic regressions were used to assess the association of case-mix factors with TO. Hospital variation was displayed using funnel plots. RESULTS A total of 1909 CRS were included, of which 1434 were interval CRS and 475 were primary CRS. TO was achieved in 54% of the interval CRS cohort and 47% of the primary CRS cohort. Macroscopic residual disease after CRS was the most important factor for not achieving TO. Age ≥ 70 was associated with lower TO rates in multivariable logistic regressions. TO rates ranged from 40% to 69% between hospitals in the interval CRS cohort and 22% to 100% in the primary CRS cohort. In both analyses, one hospital had significantly lower TO rates (different hospitals). Case-mix adjustment significantly affected TO rates in the primary CRS analysis. CONCLUSIONS TO is a suitable composite outcome measure to detect hospital variation in healthcare quality for patients with advanced-stage ovarian cancer undergoing CRS. Case-mix adjustment improves the accuracy of the hospital comparison.

Abstract
BACKGROUND Many studies have compared real-world clinical outcomes of immunotherapy in patients with metastatic non-small cell lung cancer (NSCLC) with reported outcomes data from pivotal trials. However, any differences observed could be only limitedly explored further for causation because of the unavailability of individual patient data (IPD) from trial participants. The present study aims to explore the additional benefit of comparison with IPD. METHODS This study compares progression free survival (PFS) and overall survival (OS) of metastatic NSCLC patients treated with second line nivolumab in real-world clinical practice (n = 141) with IPD from participants in the Checkmate-057 clinical trial (n = 292). Univariate and multivariate Cox proportional hazards models were used to construct HRs for real-world practice versus clinical trial. RESULTS Real-world patients were older (64 vs. 61 years), had more often ECOG PS ≥ 2 (5 vs. 0%) and were less often treated with subsequent anti-cancer treatment (28.4 vs. 42.5%) compared to trial patients. The median PFS in real-world patients was longer (3.84 (95%CI: 3.19-5.49) vs 2.30 (2.20-3.50) months) and the OS shorter than in trial participants (8.25 (6.93-13.2) vs. 12.2 (9.90-15.1) months). Adjustment with available patient characteristics, led to a shift in the hazard ratio (HR) for OS, but not for PFS (HRs from 1.13 (0.88-1.44) to 1.07 (0.83-1.38), and from 0.82 (0.66-1.03) to 0.79 (0.63-1.00), respectively). CONCLUSIONS This study is an example how IPD from both real-world and trial patients can be applied to search for factors that could explain an efficacy-effectiveness gap. Making IPD from clinical trials available to the international research community allows this.

Abstract
INTRODUCTION This study aims to develop a robust preoperative prediction model for anastomotic leakage (AL) after surgical resection for rectal cancer, based on established risk factors and with the power of a large prospective nation-wide population-based study cohort. MATERIALS AND METHODS A development cohort was formed by using the DCRA (Dutch ColoRectal Audit), a mandatory population-based repository of all patients who undergo colorectal cancer resection in the Netherlands. Patients aged 18 years or older were included who underwent surgical resection for rectal cancer with primary anastomosis (with or without deviating ileostomy) between 2011 and 2019. Anastomotic leakage was defined as clinically relevant leakage requiring reintervention. Multivariable logistic regression was used to build a prediction model and cross-validation was used to validate the model. RESULTS A total of 13.175 patients were included for analysis. AL was diagnosed in 1319 patients (10%). A deviating stoma was constructed in 6853 patients (52%). The following variables were identified as significant risk factors and included in the prediction model: gender, age, BMI, ASA classification, neo-adjuvant (chemo)radiotherapy, cT stage, distance of the tumor from anal verge, and deviating ileostomy. The model had a concordance-index of 0.664, which remained 0.658 after cross-validation. In addition, a nomogram was developed. CONCLUSION The present study generated a discriminative prediction model based on preoperatively available variables. The proposed score can be used for patient counselling and risk-stratification before undergoing rectal resection for cancer.

Abstract
Background The objective of this study was to evaluate trends in survival and health care costs in metastatic melanoma in the era of targeted and immunotherapeutic drugs. Materials and methods Data on survival and health care resource use were retrieved from the Dutch Melanoma Treatment Registry. The Kaplan–Meier method was used to estimate overall survival. Health care costs and budget impact were computed by applying unit costs to individual patient resource use. All outcomes were stratified by year of diagnosis. Results Baseline characteristics were balanced across cohort years. The percentage of patients receiving systemic treatment increased from 73% in 2013 to 90% in 2018. Patients received on average 1.85 [standard deviation (SD): 1.14] lines of treatment and 41% of patients received at least two lines of treatment. Median survival increased from 11.8 months in 2013 [95% confidence interval (CI): 10.7-13.7 months] to 21.1 months in 2018 (95% CI: 18.2 months-not reached). Total mean costs were €100 330 (SD: €103 699); systemic treatments accounted for 84% of the total costs. Costs for patients who received systemic treatment [€118 905 (SD: €104 166)] remained reasonably stable over the years even after the introduction of additional (combination of) novel drugs. From mid-2013 to 2018, the total budget impact for all patients was €452.79 million. Conclusion Our study shows a gain in survival in the era of novel targeted and immunotherapeutic drugs. These novel drugs came, however, along with substantial health care costs. Further insights into the cost-effectiveness of the novel drugs are crucial for ensuring value for money in the treatment of patients with metastatic melanoma. The median survival of patients with metastatic melanoma increased from 11.8 months in 2013 to 21.1 months in 2018. The gain in survival came along with substantial health care costs; health care costs were on average €100 300 per patient. Costs were much higher for patients with systemic treatment (€118 905) than for patients without systemic treatment (€8316). Costs for patients who received systemic treatment remained stable even after the introduction of additional novel drugs. Insights into the cost-effectiveness of the novel drugs are crucial for ensuring value for money in metastatic melanoma.

Abstract
BACKGROUND Stage IIB/IIC (8th AJCC) melanoma patients are known to have high-risk primary tumors, however they follow the same routine to sentinel lymph node biopsy (SLNB) as more low risk tumors. Guidelines are not conclusive regarding the use of preoperative imaging for these patients. The aim of this pilot study was to assess the value of ultrasound (US) and 18F-FDG PET/CT prior to lymphoscintigraphy (LSG) and SLNB for stage IIB/C melanoma patients. METHODS From 2019-04 till 2020-01, all stage IIB/C melanoma patients underwent US of the regional lymph nodes and whole body 18F-FDG PET/CT before their planned LSG and SLNB. Suspected metastases were confirmed with fine needle aspiration (FNA), prior to surgery. RESULTS In total 23 patients were screened: six had metastases detected by imaging, two by US, one by 18F-FDG PET/CT and three were detected by both imaging modalities. All metastases were nodal and therefore treatment was altered to lymph node dissection and all but one also received adjuvant therapy. Eight (47%) of the 17 patients without macroscopic disease, still had a positive SN. Sensitivity, specificity and false negative rate for US and 18F-FDG PET/CT were 36%, 89%, 64% and 29%, 100% and 71%, respectively. CONCLUSION Preoperative negative imaging does not exclude the presence of SN metastases, therefore SLNB cannot be foregone. However, US detected metastases in 22% of patients, altering their treatment, which suggests it is effective in the work-up of stage IIB/C melanoma. Staging with 18F-FDG PET/CT is not of added value prior to LSG and SLNB and should therefore not be used.

Abstract
PURPOSE Interhospital referral is a consequence of centralization of complex oncological care but might negatively impact waiting time, a quality indicator in the Netherlands. This study aims to evaluate characteristics and waiting times of patients with primary colorectal cancer who are referred between hospitals. METHODS Data were extracted from the Dutch ColoRectal Audit (2015-2019). Waiting time between first tumor-positive biopsy until first treatment was compared between subgroups stratified for referral status, disease stage, and type of hospital. RESULTS In total, 46,561 patients were included. Patients treated for colon or rectal cancer in secondary care hospitals were referred in 12.2% and 14.7%, respectively. In tertiary care hospitals, corresponding referral rates were 43.8% and 66.4%. Referred patients in tertiary care hospitals were younger, but had a more advanced disease stage, and underwent more often multivisceral resection and simultaneous metastasectomy than non-referred patients in secondary care hospitals (p<0.001). Referred patients were more often treated within national quality standards for waiting time compared to non-referred patients (p<0.001). For referred patients, longer waiting times prior to MDT were observed compared to non-referred patients within each hospital type, although most time was spent post-MDT. CONCLUSION A large proportion of colorectal cancer patients that are treated in tertiary care hospitals are referred from another hospital but mostly treated within standards for waiting time. These patients are younger but often have a more advanced disease. This suggests that these patients are willing to travel more but also reflects successful centralization of complex oncological patients in the Netherlands.

Abstract
BACKGROUND The treatment landscape has completely changed for advanced melanoma. We report survival outcomes and the differential impact of prognostic factors over time in daily clinical practice. METHODS From a Dutch nationwide population-based registry, patients with advanced melanoma diagnosed from 2013 to 2017 were analysed (n = 3616). Because the proportional hazards assumption was violated, a multivariable Cox model restricted to the first 6 months and a multivariable landmark Cox model from 6 to 48 months were used to assess overall survival (OS) of cases without missing values. The 2017 cohort was excluded from this analysis because of the short follow-up time. RESULTS Median OS of the 2013 and 2016 cohort was 11.7 months (95% confidence interval [CI]: 10.4-13.5) and 17.7 months (95% CI: 14.9-19.8), respectively. Compared with the 2013 cohort, the 2016 cohort had superior survival in the Cox model from 0 to 6 months (hazard ratio [HR] = 0.55 [95% CI: 0.43-0.72]) and in the Cox model from 6 to 48 months (HR = 0.68 [95% CI: 0.57-0.83]). Elevated lactate dehydrogenase levels, distant metastases in ≥3 organ sites, brain and liver metastasis and Eastern Cooperative Oncology Group performance score of ≥1 had stronger association with inferior survival from 0 to 6 months than from 6 to 48 months. BRAF-mutated melanoma had superior survival in the first 6 months (HR = 0.50 [95% CI: 0.42-0.59]). CONCLUSION(S) Prognosis for advanced melanoma in the Netherlands has improved from 2013 to 2016. Prognostic importance of most evaluated factors was higher in the first 6 months after diagnosis. BRAF-mutated melanoma was only associated with superior survival in the first 6 months.

Abstract
BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive tumour. Adequate margins have a positive impact on recurrence rates. The aim of this study is to assess how adequate margins are achieved and secondly which additional treatment modalities might be necessary to achieve adequate margins. MATERIAL & METHODS Patients with DFSP treated between 1991 and 2016 at three tertiary centres were included. Patient- and tumour characteristics were obtained from a prospectively held database and patient files. RESULTS A total of 279 patients with a median age of 39 (Interquartile range [IQ], 31-50) years and a median follow-up of 50 (IQ, 18-96) months were included. When DFSP was preoperatively confirmed by biopsy and resected with an oncological operation in a tertiary centre, in 86% was had clear pathological margins after one excision. Wider resection margins were significantly correlated with more reconstructions (p = 0.002). A substantial discrepancy between the primary surgical macroscopic and the pathological margins was found with a median difference of 22 (range, 10-46) mm (Fig. 1). There was no significant influence of the width of the pathological clear margins (if > 1 mm) and the recurrence rate (p = 0.710). CONCLUSION The wider the resection margins, the more likely it is to obtain clear pathological margins, but the more likely patients will need any form of reconstruction after resection. The aim of the primary excision should be wide surgical resection, where the width of the margin should be balanced against the need for reconstructions and surgical morbidity.

Abstract
Background In patients with colorectal liver metastases (CRLM) preoperative imaging may include contrast‐enhanced (ce) MRI and [18F]fluorodeoxyglucose (18F‐FDG) PET–CT. This study assessed trends and variation between hospitals and oncological networks in the use of preoperative imaging in the Netherlands. Methods Data for all patients who underwent liver resection for CRLM in the Netherlands between 2014 and 2018 were retrieved from a nationwide auditing database. Multivariable logistic regression analysis was used to assess use of ceMRI, 18F‐FDG PET–CT and combined ceMRI and 18F‐FDG PET–CT, and trends in preoperative imaging and hospital and oncological network variation. Results A total of 4510 patients were included, of whom 1562 had ceMRI, 872 had 18F‐FDG PET–CT, and 1293 had combined ceMRI and 18F‐FDG PET–CT. Use of ceMRI increased over time (from 9·6 to 26·2 per cent; P < 0·001), use of 18F‐FDG PET–CT decreased (from 28·6 to 6·0 per cent; P < 0·001), and use of both ceMRI and 18F‐FDG PET–CT 16·9 per cent) remained stable. Unadjusted variation in the use of ceMRI, 18F‐FDG PET–CT, and combined ceMRI and 18F‐FDG PET–CT ranged from 5·6 to 100 per cent between hospitals. After case‐mix correction, hospital and oncological network variation was found for all imaging modalities. Discussion Significant variation exists concerning the use of preoperative imaging for CRLM between hospitals and oncological networks in the Netherlands. The use of MRI is increasing, whereas that of 18F‐FDG PET–CT is decreasing.

Abstract
INTRODUCTION Kaposi sarcoma (KS) is a rare soft tissue sarcoma. In case of locally advanced disease, mutilating surgery such as amputations or major reconstructive procedures are sometimes inevitable. The aim of this study was to evaluate the effectiveness of isolated limb perfusion (ILP) in patients with locally advanced KS of the extremities. MATERIAL AND METHODS All patients who underwent ILP for KS between 1996 and 2018 at Erasmus MC, Rotterdam were identified. Clinical data was obtained from either a prospectively maintained database or retrospective assessment of patient files. RESULTS A total of 14 primary ILP's were performed in 11 patients. Median follow-up from primary ILP was 30 months (range, 5-98). The overall response rate of primary ILP was 100%, with a complete response (CR) rate of 50%. Only minimal local toxicity (Wieberdink I-III) was observed. Local progressive disease occurred after eight primary ILP's (57%) with a median local progression free survival (PFS) of 18 months (95% confidence interval [CI]: 7.0-28.9). Subsequently, four (46%) patients received a total of 5 recurrent ILP's. After the recurrent ILP on the same leg, the overall response rate was 75% and a CR-rate of 50%. One patient needed amputation post-operatively resulting in a limb salvage rate of 91%. One (9%) patient developed metastases four months after ILP. CONCLUSIONS ILP is a highly effective treatment modality with very limited morbidity rates for patients with locally advanced KS of the extremity. ILP should be considered as a treatment modality for locally advanced KS of the extremities.

Abstract
AIM This study aimed to determine predictive factors for the circumferential resection margin (CRM) within two northern European countries with supposed similarity in providing rectal cancer care. METHOD Data for all patients undergoing rectal resection for clinical tumour node metastasis (TNM) stage I-III rectal cancer were extracted from the Swedish ColoRectal Cancer Registry and the Dutch ColoRectal Audit (2011-2015). Separate analyses were performed for cT1-3 and cT4 stage. Predictive factors for the CRM were determined using univariable and multivariable logistic regression analyses. RESULTS A total of 6444 Swedish and 12 089 Dutch patients were analysed. Over time the number of hospitals treating rectal cancer decreased from 52 to 42 in Sweden, and 82 to 79 in the Netherlands. In the Swedish population, proportions of cT4 stage (17% vs 8%), multivisceral resection (14% vs 7%) and abdominoperineal excision (APR) (37% vs 31%) were higher. The overall proportion of patients with a positive CRM (CRM+) was 7.8% in Sweden and 5.4% in the Netherlands. In both populations with cT1-3 stage disease, common independent risk factors for CRM+ were cT3, APR and multivisceral resection. No common risk factors for CRM+ in cT4 stage disease were found. An independent impact of hospital volume on CRM+ could be demonstrated for the cT1-3 Dutch population. CONCLUSION Within two northern European countries with implemented clinical auditing, rectal cancer care might potentially be improved by further optimizing the treatment of distal and locally advanced rectal cancer.

Abstract
Background Clinical auditing is an emerging instrument for quality assessment and improvement. Moreover, clinical registries facilitate medical research as they provide ‘real world’ data. It is important that entered data are robust and reliable. The aim of this study was to describe the evolving procedure and results of data verification within the Dutch Institute for Clinical Auditing (DICA). Methods Data verification performed on several (disease‐specific) clinical registries between 2013 and 2015 was evaluated. Sign‐up, sample size and process of verification were described. For each procedure, hospitals were visited by external data managers to verify registered data. Outcomes of data verification were completeness and accuracy. An assessment of the quality of data was given per registry, for each participating hospital. Using descriptive statistics, analyses were performed for different sections within the individual registries. Results Seven of the 21 registries were verified, involving 174 visits to hospital departments. A step‐by‐step description of the data verification process was provided. Completeness of data in the registries varied from 97·2 to 99·4 per cent. Accuracy of data ranged from 88·2 to 100 per cent. Most discrepancies were observed for postoperative complications (0·7–7·5 per cent) and ASA classification (8·5–11·4 per cent). Data quality was assessed as ‘sufficient’ for 145 of the 174 hospital departments (83·3 per cent). Conclusion Data verification revealed that the data entered in the observed DICA registries were complete and accurate.

Abstract
Background Benchmarking on an international level might lead to improved outcomes at a national level. The aim of this study was to compare treatment and surgical outcome data from the Swedish National Register for Oesophageal and Gastric Cancer (NREV) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA). Methods All patients with primary oesophageal or gastric cancer who underwent a resection and were registered in NREV or DUCA between 2012 and 2014 were included. Differences in 30‐day mortality were analysed using case mix‐adjusted multivariable logistic regression. Results In total, 4439 patients underwent oesophagectomy (2509 patients) or gastrectomy (1930 patients). Estimated resection rates were comparable. Swedish patients were older but had less advanced disease and less co‐morbidity than Dutch patients. Neoadjuvant treatment rates were lower in Sweden than in the Netherlands, both for patients who underwent oesophagectomy (68·6 versus 90·0 per cent respectively; P < 0·001) and for those having gastrectomy (38·3 versus 56·6 per cent; P < 0·001). In Sweden, transthoracic oesophagectomy was performed in 94·7 per cent of patients, whereas in the Netherlands, a transhiatal approach was undertaken in 35·8 per cent. Higher annual procedural volumes per hospital were observed in the Netherlands. Adjusted 30‐day and/or in‐hospital mortality after gastrectomy was statistically significantly lower in Sweden than in the Netherlands (odds ratio 0·53, 95 per cent c.i. 0·29 to 0·95). Conclusion For oesophageal and gastric cancer, there are differences in patient, tumour and treatment characteristics between Sweden and the Netherlands. Postoperative mortality in patients with gastric cancer was lower in Sweden.

Abstract
Quality indicators are used to measure quality of care and enable benchmarking. An overview of all existing hip fracture quality indicators is lacking. The primary aim was to identify quality indicators for hip fracture care reported in literature, hip fracture audits, and guidelines. The secondary aim was to compose a set of methodologically sound quality indicators for the evaluation of hip fracture care in clinical practice. A literature search according to the PRISMA guidelines and an internet search were performed to identify hip fracture quality indicators. The indicators were subdivided into process, structure, and outcome indicators. The methodological quality of the indicators was judged using the Appraisal of Indicators through Research and Evaluation (AIRE) instrument. For structure and process indicators, the construct validity was assessed. Sixteen publications, nine audits and five guidelines were included. In total, 97 unique quality indicators were found: 9 structure, 63 process, and 25 outcome indicators. Since detailed methodological information about the indicators was lacking, the AIRE instrument could not be applied. Seven indicators correlated with an outcome measure. A set of nine quality indicators was extracted from the literature, audits, and guidelines. Many quality indicators are described and used. Not all of them correlate with outcomes of care and have been assessed methodologically. As methodological evidence is lacking, we recommend the extracted set of nine indicators to be used as the starting point for further clinical research. Future research should focus on assessing the clinimetric properties of the existing quality indicators.

Abstract
BACKGROUND Monitoring time trends of cancer mortality is essential. Thirty-day mortality is an important surgical outcome measure, though postoperative mortality exceeds to one year after surgery in patients with colorectal cancer. The aim of this nationwide observational study was to assess changes over time in 30-day and one-year mortality in patients with stage I-III colorectal cancer. METHODS All surgically treated patients with stage I-III colorectal cancer, diagnosed between 2009 and 2013 were selected from the Netherlands Cancer Registry. Changes in 30-day and one-year mortality were assessed using logistic regression by tumour localisation (colon, rectum) and age group (<75 years, ≥75 years). RESULTS Overall, 41,186 patients were included. Among patients with colon cancer ≥75 years, 30-day mortality decreased from 8.3% in 2009 to 6.2% in 2013 (p-value for trend = 0.011), and one-year mortality from 18.5% in 2009 to 15.0% in 2013 (p-value for trend = 0.007). No significant differences in mortality over time were observed for patients <75 years with colon cancer and for patients with rectal cancer. CONCLUSION Thirty-day and one-year mortality decreased over time in patients ≥75 years with stage I-III colon cancer, though the absolute decrease is small. However, 30-day mortality and in particular the one-year mortality are both still high in older patients with colorectal cancer and will need to be focused on to further improve outcomes for these patient subgroups.

Abstract
BACKGROUND The introduction of endovascular aneurysm repair (EVAR) has reduced perioperative mortality after abdominal aortic aneurysm (AAA) surgery. The objective of this systematic review was to assess existing mortality risk prediction models, and identify which are most useful for patients undergoing AAA repair by either EVAR or open surgical repair. METHODS A systematic search of the literature was conducted for perioperative mortality risk prediction models for patients with AAA published since 2006. PRISMA guidelines were used; quality was appraised, and data were extracted and interpreted following the CHARMS guidelines. RESULTS Some 3903 studies were identified, of which 27 were selected. A total of 13 risk prediction models have been developed and directly validated. Most models were based on a UK or US population. The best performing models regarding both applicability and discrimination were the perioperative British Aneurysm Repair score (C-statistic 0·83) and the preoperative Vascular Biochemistry and Haematology Outcome Model (C-statistic 0·85), but both lacked substantial external validation. CONCLUSION Mortality risk prediction in AAA surgery has been modelled extensively, but many of these models are weak methodologically and have highly variable performance across different populations. New models are unlikely to be helpful; instead case-mix correction should be modelled and adapted to the population of interest using the relevant mortality predictors.

Abstract
OBJECTIVE/BACKGROUND The Dutch Surgical Aneurysm Audit (DSAA) is mandatory for all patients with primary abdominal aortic aneurysms (AAAs) in the Netherlands. The aims are to present the observed outcomes of AAA surgery against the predicted outcomes by means of V-POSSUM (Vascular-Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity). Adjusted mortality was calculated by the original and re-estimated V(physiology)-POSSUM for hospital comparisons. METHODS All patients operated on from January 2013 to December 2014 were included for analysis. Calibration and discrimination of V-POSSUM and V(p)-POSSUM was analysed. Mortality was benchmarked by means of the original V(p)-POSSUM formula and risk-adjusted by the re-estimated V(p)-POSSUM on the DSAA. RESULTS In total, 5898 patients were included for analysis: 4579 with elective AAA (EAAA) and 1319 with acute abdominal aortic aneurysm (AAAA), acute symptomatic (SAAA; n = 371) or ruptured (RAAA; n = 948). The percentage of endovascular aneurysm repair (EVAR) varied between hospitals but showed no relation to hospital volume (EAAA: p = .12; AAAA: p = .07). EAAA, SAAA, and RAAA mortality was, respectively, 1.9%, 7.5%, and 28.7%. Elective mortality was 0.9% after EVAR and 5.0% after open surgical repair versus 15.6% and 27.4%, respectively, after AAAA. V-POSSUM overestimated mortality in most EAAA risk groups (p < .01). The discriminative ability of V-POSSUM in EAAA was moderate (C-statistic: .719) and poor for V(p)-POSSUM (C-statistic: .665). V-POSSUM in AAAA repair overestimated in high risk groups, and underestimated in low risk groups (p < .01). The discriminative ability in AAAA of V-POSSUM was moderate (.713) and of V(p)-POSSUM poor (.688). Risk adjustment by the re-estimated V(p)-POSSUM did not have any effect on hospital variation in EAAA but did in AAAA. CONCLUSION Mortality in the DSAA was in line with the literature but is not discriminative for hospital comparisons in EAAA. Adjusting for V(p)-POSSUM, revealed no association between hospital volume and treatment or outcome. Risk adjustment for case mix by V(p)-POSSUM in patients with AAAA has been shown to be important.

Abstract
BACKGROUND Quality assurance is acknowledged as a crucial factor in the assessment of oncological surgical care. The aim of this study was to develop a composite measure of multiple outcome parameters defined as 'textbook outcome', to assess quality of care for patients undergoing oesophagogastric cancer surgery. METHODS Patients with oesophagogastric cancer, operated on with the intent of curative resection between 2011 and 2014, were identified from a national database (Dutch Upper Gastrointestinal Cancer Audit). Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. Hospital variation in textbook outcome was analysed after adjustment for case-mix factors. RESULTS In total, 2748 patients with oesophageal cancer and 1772 with gastric cancer were included in this study. A textbook outcome was achieved in 29·7 per cent of patients with oesophageal cancer and 32·1 per cent of those with gastric cancer. Adjusted textbook outcome rates varied from 8·5 to 52·4 per cent between hospitals. The outcome parameter 'at least 15 lymph nodes examined' had the greatest negative impact on a textbook outcome both for patients with oesophageal cancer and for those with gastric cancer. CONCLUSION Most patients did not achieve a textbook outcome and there was wide variation between hospitals.

Abstract
We have recently shown that costs of surgical treatment for colorectal carcinoma differ greatly between various patient groups in the Netherlands. Those cost-differences could mostly be explained by the fact that high-risk patients have a greater risk of complications, which generate higher hospital costs. Hospitals with a high-risk population, for instant tertiary referral centres, spend more than hospitals that treat low-risk patients. Currently reimbursement however is not geared to risk differences. In this article we investigate this shortcoming of the current reimbursement system and discuss how a differential rewarding - in which reimbursement is aligned with the patient's risk profile - could serve as a tool to further quality improvement in healthcare. Current clinical registries may provide the necessary details of patient characteristics for risk profiling and may also contribute to the following goal: reimbursement based on the quality of delivered care.

Abstract
OBJECTIVE To investigate the impact of the Netherlands national colorectal cancer screening programme on the number of surgical resections for colorectal carcinoma and on waiting times for surgery. DESIGN Descriptive study. METHOD Data were extracted from the Dutch Surgical Colorectal Audit. Patients with primary colorectal cancer surgery between 2011-2015 were included. The volume and median waiting times for the years 2011-2015 are described. Waiting times from first tumor positive biopsy until the operation (biopsy-operation) and first preoperative visit to the surgeon until the operation (visit-operation) are analyzed with a univariate and multivariate linear regression analysis. Separate analysis was done for visit-operation for academic and non-academic hospitals and for screening compared to non-screening patients. RESULTS In 2014 there was an increase of 1469 (15%) patients compared to 2013. In 2015 this increase consisted of 1168 (11%) patients compared to 2014. In 2014 and 2015, 1359 (12%) and 3111 (26%) patients were referred to the surgeon through screening, respectively. The median waiting time of biopsy-operation significantly decreased (ß: 0.94, 95%BI) over the years 2014-2015 compared to 2011-2013. In non-academic hospitals, the waiting time visit-operation also decreased significantly (ß: 0.89, 95%BI 0.87-0.90) over the years 2014-2015 compared to 2011-2013. No difference was found in waiting times between patients referred to the surgeon through screening compared to non-screening. CONCLUSION There is a clear increase in volume since the introduction of the colorectal cancer screening programme without an increase in waiting time until surgery.

Abstract
Abstract
Background
In 2011, the Dutch Upper Gastrointestinal Cancer Audit (DUCA) group began nationwide registration of all patients undergoing surgery with the intention of resection for oesophageal or gastric cancer. The aim of this study was to describe the initiation and implementation of this process along with an overview of the results.
Methods
The DUCA is part of the Dutch Institute for Clinical Auditing. The audit provides (surgical) teams with reliable, weekly updated, benchmarked information on process and (case mix-adjusted) outcome measures. To accomplish this, a web-based registration was designed, based on a set of predefined quality measures.
Results
Between 2011 and 2014, a total of 2786 patients with oesophageal cancer and 1887 with gastric cancer were registered. Case ascertainment approached 100 per cent for patients registered in 2013. The percentage of patients with oesophageal cancer starting treatment within 5 weeks of diagnosis increased significantly over time from 32·5 per cent in 2011 to 41·0 per cent in 2014 (P < 0·001). The percentage of patients with a minimum of 15 examined lymph nodes in the resected specimen also increased significantly for both oesophageal cancer (from 50·3 per cent in 2011 to 73·0 per cent in 2014; P < 0·001) and gastric cancer (from 47·5 per cent in 2011 to 73·6 per cent in 2014; P < 0·001). Postoperative mortality remained stable (around 4·0 per cent) for patients with oesophageal cancer, and decreased for patients with gastric cancer (from 8·0 per cent in 2011 to 4·0 per cent in 2014; P = 0·031).
Conclusion
Nationwide implementation of the DUCA has been successful. The results indicate a positive trend for various process and outcome measures.

Abstract
Surgery still is the cornerstone of treatment for patients with stage II and III melanoma, but despite great efforts to gain or preserve locoregional control with excision of the primary tumour, satellites, intransits, sentinel node biopsy and lymphadenectomy, surgery alone does not seem to improve survival any further. Prognosis for patients with high risk melanoma remains poor with 5-year survival rates of 40 to 80%. Only interferon-2b has been approved as adjuvant therapy since 1995, but clinical integration is low considering the high risk-benefit ratio. In recent years systemic targeted- and immunotherapy have proven to be beneficial in advanced melanoma and could be a promising strategy for (neo)adjuvant treatment of patients with resectable high risk melanomas as well. Randomised, placebo- controlled phase III trials on adjuvant systemic targeted- and immunotherapy are currently being performed using new agents like ipilimumab, pembrolizumab, nivolumab, vemurafenib and dabrafenib plus trametinib. In this article we review the literature on currently known adjuvant therapies and currently ongoing trials of (neo)adjuvant therapies in high risk melanomas.

Abstract
Abstract
Background
The aim of this study was to provide a systematic and quantitative summary of the association between laparoscopic Roux-en-Y gastric bypass (LRYGB) and the reported incidence of internal herniation (IH). The route of the Roux limb and closure of mesenteric and/or mesocolonic defects are described as factors of influence.
Methods
MEDLINE, Embase, the Cochrane Library and Web of Science were searched for relevant literature, references and citations according to the PRISMA statement. Two independent reviewers selected studies that evaluated incidence of IH after LRYGB and possible techniques for prevention. Data were pooled by route of the Roux limb and closure/non-closure of the mesenteric and/or mesocolonic defects.
Results
Forty-five articles included data on 31 320 patients. Lowest IH incidence was in the antecolic group, with closure of all defects (1 per cent; P < 0·001), followed by the antecolic group, with all defects left open and the retrocolic group with closure of the mesenteric and mesocolonic defect (both 2 per cent; P < 0·001). The incidence of IH was highest in the antecolic group, with closure of the jejunal defect, and in the retrocolic group, with closure of all defects (both 3 per cent).
Conclusion
The present systematic review includes a random-effects meta-analysis. The antecolic procedure, with closure of both the mesenteric and Petersen defects, has the lowest internal herniation incidence following laparoscopic Roux-en-Y gastric bypass.

Abstract
AIM The study included investigation of factors determining suboptimal adjuvant chemotherapy of patients diagnosed with Stage III colon cancer. METHOD All 606 patients diagnosed with Stage III colon cancer between 2006 and 2008 in the western part of the Netherlands were included. Patient [gender, age, comorbidity and socio-economic status (SES)], tumour (location, stage and grade) and treatment (emergency surgery, laparoscopic surgery, reoperation, hospital stay and multidisciplinary meeting) factors were examined in logistic regression analyses predicting a complicated postoperative period and omission, delay and discontinuation of adjuvant chemotherapy. RESULTS Overall, 27% of all patients experienced a complicated postoperative period, which was independently associated with emergency surgery, older age, multiple comorbidity, male gender and poor tumour grade. Of patients who survived this period, 60% received chemotherapy. Chemotherapy was omitted more often in women, the elderly and in patients with Stage IIIB, reoperation, prolonged hospital stay and (borderline) after open surgery. Of patients who received chemotherapy, 86% started within 8 weeks after surgery. Patients with a higher SES, reoperation and prolonged hospital stay had a higher probability of a delayed start. Sixty-seven per cent of patients completed their chemotherapy. For women, elderly patients and patients with prolonged hospital stay a higher probability of discontinuation was noted. CONCLUSION Age was the most important predictive factor for receiving adjuvant chemotherapy. However, at all ages, complicated postoperative recovery negatively influenced the administration of chemotherapy to Stage III colon cancer patients, as well as a timely start and completion of chemotherapy.

Abstract
BACKGROUND Centralization of pancreatic surgery has been shown to reduce postoperative mortality. It is unknown whether resection rates and survival have also improved. The aim of this study was to analyse the impact of nationwide centralization of pancreatic surgery on resection rates and long-term survival. METHODS All patients diagnosed in the Netherlands between 2000 and 2009 with cancer of the pancreatic head were identified in the Netherlands Cancer Registry. Changes in referral pattern, resection rates and survival after pancreatoduodenectomy were analysed. Multivariable regression analysis was used to assess the impact of hospital volume (20 or more procedures per year) on survival after resection. RESULTS Between 2000 and 2009, 11,160 patients were diagnosed with cancer of the pancreatic head. The resection rate increased from 10.7 per cent in 2000-2004 to 15.3 per cent in 2005-2009 (P < 0.001). No significant difference in survival after resection was observed between the two intervals (P = 0.135), although survival was significantly better in high-volume hospitals (median survival 18 months versus 16 months in low/medium-volume hospitals; P = 0.017). After adjustment for patient and tumour characteristics, high hospital volume remained associated with better overall survival after resection (hazard ratio 0.70, 95 per cent confidence interval 0.58 to 0.84; P < 0.001). CONCLUSION Centralization of pancreatic cancer surgery led to increased resection rates. High-volume centres had significantly better survival rates. Centralization improves patient outcomes and should be encouraged.

Abstract
Studies investigating perioperative chemotherapy and/or radiotherapy changed the treatment of curable gastric cancer in The Netherlands. These changes were evaluated including their influence on survival. Data on patients diagnosed with gastric cancer from 1989 to 2009 were obtained from The Netherlands Cancer Registry. Changes over time in surgery and administration of perioperative chemotherapy, 30-day mortality, 5-year survival and adjusted relative excess risk (RER) of dying were analyzed with multivariable regression for cardia and noncardia cancer. In stages I and II disease, most patients underwent surgery. Since 2005, more patients are treated with (neo)adjuvant chemotherapy. Postoperative mortality ranged from 1% to 7% and 0.4% to 12.2% in cardia and noncardia cancer (<55 to 75+ years). Five-year survival for cardia cancer and noncardia cancer stages I-III and X (unknown stage) was 33% and 50% (2005-2008). The RER of dying was associated with period of diagnosis, age, gender, region, stage, (neo)adjuvant chemotherapy in case of cardia cancer and type of gastric resection in case of noncardia cancer. Administration of (neo)adjuvant chemotherapy has increased. No improvement in long-term survival could yet be seen, though it is still too early to expect an improvement in survival as a result of the use of chemotherapy.

Abstract
INTRODUCTION When comparing mortality rates between hospitals to explore hospital performance, there is an important role for adjustment for differences in case-mix. Identifying outcome measures that are less influenced by differences in case-mix may be valuable. The main goal of this study was to explore whether hospital differences in anastomotic leakage (AL) and postoperative mortality are due to differences in case-mix or to differences in treatment factors. METHODS Data of the Dutch Surgical Colorectal Audit were used. Case-mix factors and treatment-related factors were identified from the literature and their association with AL and mortality were analysed with logistic regression. Hospital differences in observed AL and mortality rates, and adjusted rates based on the logistic regression models were shown. The reduction in hospital variance after adjustment was analysed with Levene's test for equality of variances. RESULTS 17 of 22 case-mix factors and 4 of 11 treatment factors related to AL derived from the literature were available in the database. Variation in observed AL rates between hospitals was large with a maximum rate of 17%. This variation could not be attributed to differences in case-mix but more to differences in treatment factors. Hospital variation in observed mortality rates was significantly reduced after adjustment for differences in case-mix. CONCLUSIONS Hospital variation in AL is relatively independent of differences in case-mix. In contrast to 'postoperative mortality' the observed AL rates of hospitals evaluated in our study were only slightly affected after adjustment for case-mix factors. Therefore, AL rates may be suitable as an outcome indicator for measurement of surgical quality of care.

Abstract
BACKGROUND Postoperative mortality is frequently used in hospital comparisons as marker for quality of care. Differences in mortality between hospitals may be explained by varying complication rates. A possible modifying factor may be the ability to let patients with a serious complication survive, referred to as failure to rescue (FTR). The purpose of this study was to evaluate how hospital performance on postoperative mortality is related to severe complications or to FTR and to explore the value of FTR in quality improvement programs. METHODS All patients operated for colorectal cancer from 2009 to 2011, registered in the Dutch Surgical Colorectal Audit, were included. Logistic regression models were used to obtain adjusted mortality, complication, and FTR rates. Hospitals were grouped into 5 quintiles according to adjusted mortality. Outcomes were compared between quintiles. RESULTS A total of 24,667 patients were included. Severe complications ranged from 19 % in the lowest to 25 % in the highest mortality quintile (odds ratio 1.5, 95 % confidence interval 1.37-1.67). Risk-adjusted FTR rates showed a marked difference between the quintiles, ranging from 9 % to 26 % (odds ratio 3.0, 95 % confidence interval 2.29-3.98). There was significant variability in FTR rates. Seven hospitals had significantly lower FTR rates than average. CONCLUSIONS High-mortality hospitals had slightly higher rates of severe complications than low-mortality hospitals. However, FTR was three times higher in high-mortality hospitals than in low-mortality hospitals. In quality improvement projects, feedback to hospitals of FTR rates, along with complication rates, may illustrate shortcomings (prevention or management of complications) per hospital, which may be an important step in reducing mortality.

Abstract
AIMS The aim of the study was to assess which factors contribute to postoperative mortality, especially in elderly patients who undergo emergency colon cancer resections, using a nationwide population-based database. METHODS 6,161 patients (1,172 nonelective) who underwent a colon cancer resection in 2010 in the Netherlands were included. Risk factors for postoperative mortality were investigated using a multivariate logistic regression model for different age groups, elective and nonelective patients separately. RESULTS For both elective and nonelective patients, mortality risk increased with increasing age. For nonelective elderly patients (80+ years), each additional risk factor increased the mortality risk. For a nonelective patient of 80+ years with an American Society of Anesthesiologists score of III+ and a left hemicolectomy or extended resection, postoperative mortality rate was 41% compared with 7% in patients without additional risk factors. CONCLUSIONS For elderly patients with two or more additional risk factors, a nonelective resection should be considered a high-risk procedure with a mortality risk of up to 41%. The results of this study could be used to adequately inform patient and family and should have consequences for composing an operative team.

Abstract
BACKGROUND In several European countries, centralization of oesophagogastric cancer surgery has been realized and clinical audits initiated. The present study was designed to evaluate differences in resection rates, outcomes and annual hospital volumes between these countries, and to analyse the relationship between hospital volume and outcomes. METHODS National data were obtained from cancer registries or clinical audits in the Netherlands, Sweden, Denmark and England. Differences in outcomes were analysed between countries and between hospital volume categories, adjusting for available case-mix factors. RESULTS Between 2004 and 2009, 10 854 oesophagectomies and 9010 gastrectomies were registered. Resection rates in England were 18·2 and 21·6 per cent for oesophageal and gastric cancer respectively, compared with 28·5-29·9 and 41·4-41·9 per cent in the Netherlands and Denmark (P < 0·001). The adjusted 30-day mortality rate after oesophagectomy was lowest in Sweden (1·9 per cent). After gastrectomy, the adjusted 30-day mortality rate was significantly higher in the Netherlands (6·9 per cent) than in Sweden (3·5 per cent; P = 0·017) and Denmark (4·3 per cent; P = 0·029). Increasing hospital volume was associated with a lower 30-day mortality rate after oesophagectomy (odds ratio 0·55 (95 per cent confidence interval 0·42 to 0·72) for at least 41 versus 1-10 procedures per year) and gastrectomy (odds ratio 0·64 (0·41 to 0·99) for at least 21 versus 1-10 procedures per year). CONCLUSION Hospitals performing larger numbers of oesophagogastric cancer resections had a lower 30-day mortality rate. Differences in outcomes between several European countries could not be explained by differences in hospital volumes. To understand these differences in outcomes and resection rates, with reliable case-mix adjustments, a uniform European upper gastrointestinal cancer audit with recording of standardized data is warranted.

Abstract
Comorbidity has large impact on colorectal cancer (CRC) treatment and outcomes and may increase as the population ages. We aimed to evaluate the prevalence and time trends of comorbid diseases in patients with CRC from 1995 to 2010. The Eindhoven Cancer Registry registers comorbidity in all patients with primary CRC in the South of the Netherlands. We analyzed the prevalence of serious comorbid diseases in four time frames from 1995 to 2010. Thereby, we addressed its association with age, gender and socio-economic status (SES). The prevalence of comorbidity was registered in 27,339 patients with primary CRC. During the study period, the prevalence of comorbidity increased from 47% to 62%, multimorbidity increased from 20% to 37%. Hypertension and cardiovascular diseases were most prevalent and increased largely over time (respectively 16-29% and 12-24%). Pulmonary diseases increased in women, but remained stable in men. Average age at diagnosis increased from 68.3 to 69.5 years (p = 0.004). A low SES and male gender were associated with a higher risk of comorbidity (not changing over time). This study indicates that comorbidity among patients with CRC is common, especially in males and patients with a low SES. The prevalence of comorbidity increased from 1995 to 2010, in particular in presumably nutritional diseases. Ageing, increased life expectancy and life style changes may contribute to more comorbid diseases. Also, improved awareness among health care providers on the importance of comorbidity may have resulted in better registration. The increasing burden of comorbidity in patients with CRC emphasizes the need for more focus on individualized medicine.

Abstract
AIMS We propose a summarizing measure for outcome indicators, representing the proportion of patients for whom all desired short-term outcomes of care (a 'textbook outcome') is realized. The aim of this study was to investigate hospital variation in the proportion of patients with a 'textbook outcome' after colon cancer resections in the Netherlands. METHODS Patients who underwent a colon cancer resection in 2010 in the Netherlands were included in the Dutch Surgical Colorectal Audit. A textbook outcome was defined as hospital survival, radical resection, no reintervention, no ostomy, no adverse outcome and a hospital stay < 14 days. We calculated the number of hospitals with a significantly higher (positive outlier) or lower (negative outlier) Observed/Expected (O/E) textbook outcome than average. As quality measures may be more discriminative in a low-risk population, analyses were repeated for low-risk patients only. RESULTS A total of 5582 patients, treated in 82 hospitals were included. Average textbook outcome was 49% (range 26-71%). Eight hospitals were identified as negative outliers. In these hospitals a 'textbook outcome' was realized in 35% vs. 52% in average hospitals (p < 0.01). In a sub-analysis for low-risk patients, only one additional negative outlier was identified. CONCLUSIONS The textbook outcome, representing the proportion of patients with a perfect hospitalization, gives a simple comprehensive summary of hospital performance, while preventing indicator driven practice. Therewith the 'textbook outcome' is meaningful for patients, providers, insurance companies and healthcare inspectorate.

Abstract
BACKGROUND Availability of anastomotic leakage rates and mortality rates following anastomotic leakage is essential when informing patients with rectal cancer preoperatively. We performed a meta-analysis of studies describing anastomotic leakage and the subsequent postoperative mortality in relation to the overall postoperative mortality after low anterior resection for rectal cancer. METHODS A systematic search was performed of the published literature. Data on the definition and incidence rate of AL, postoperative mortality caused by AL, and overall postoperative mortality were extracted. Data were pooled and a meta-analysis was performed. RESULTS Twenty-two studies with 10,343 patients in total were analyzed. Meta-analysis of the data showed an average AL rate of 9%, postoperative mortality caused by leakage of 0.7% and overall postoperative mortality of 2%. The studies showed variation in incidence, definition and measurement of all outcomes. CONCLUSION We found a considerable overall AL rate and a large contribution of AL to the overall postoperative mortality. The variability of definitions and measurement of AL, postoperative mortality caused by leakage and overall postoperative mortality may hinder providing reliable risk information. Large-scale audit programs may provide accurate and valid risk information which can be used for preoperative decision making.

Abstract
BACKGROUND Outcomes after oesophagectomy and gastrectomy vary considerably between hospitals. Possible explanations include differences in case mix, hospital volume and hospital type. The present study examined the distribution of oesophagectomies and gastrectomies between hospital types in the Netherlands, and the relationship between hospital type and outcome. METHODS Data were obtained from the nationwide Netherlands Cancer Registry. Hospitals were categorized as university hospitals (UH), non-university teaching hospitals (NUTH) and non-university non-teaching hospitals (NUNTH). Hospital type-outcome relationships were analysed by Cox regression, adjusting for case mix, hospital volume, year of diagnosis and use of multimodal therapies. RESULTS Between 1989 and 2009, 10 025 oesophagectomies and 14 221 gastrectomies for cancer were performed in the Netherlands. The percentage of oesophagectomies and gastrectomies performed in UH increased from 17·6 and 6·4 per cent respectively in 1989 to 44·1 and 12·9 per cent in 2009. After oesophagectomy, the 3-month mortality rate was 2·5 per cent in UH, 4·4 per cent in NUTH and 4·1 per cent in NUNTH (P = 0·006 for UH versus NUTH). After gastrectomy, the 3-month mortality rate was 4·9 per cent in UH, 8·9 per cent in NUTH and 8·7 per cent in NUNTH (P < 0·001 for UH versus NUTH). Three-year survival was also higher in UH than in NUTH and NUNTH. CONCLUSION Oesophagogastric resections performed in UH were associated with better outcomes but, owing to variation in outcomes within hospital types, centres of excellence cannot be designated solely on hospital type. Detailed information on case mix and outcomes is needed to identify centres of excellence.

Abstract
BACKGROUND Many studies have shown lower mortality and higher survival rates after pancreatic surgery with high-volume providers, suggesting that centralization of pancreatic surgery can improve outcomes. The methodological quality of these studies is open to question. This study involves a systematic review of the volume-outcome relationship for pancreatic surgery with a meta-analysis of studies considered to be of good quality. METHODS A systematic search of electronic databases up to February 2010 was performed to identify all primary studies examining the effects of hospital or surgeon volume on postoperative mortality and survival after pancreatic surgery. All articles were critically appraised with regard to methodological quality and risk of bias. After strict inclusion, meta-analysis assuming a random-effects model was done to estimate the effect of higher surgeon or hospital volume on patient outcome. RESULTS Fourteen studies were included in the meta-analysis. The results showed a significant association between hospital volume and postoperative mortality (odds ratio 0.32, 95 per cent confidence interval 0.16 to 0.64), and between hospital volume and survival (hazard ratio 0.79, 0.70 to 0.89).The effect of surgeon volume on postoperative mortality was not significant (odds ratio 0.46, 0.17 to 1.26). Significant heterogeneity was seen in the analysis of hospital volume and mortality. Sensitivity analysis showed no correlation with the extent of risk adjustment or study country; after removing one outlier study, the result was homogeneous. The data did not suggest publication bias. CONCLUSION There was a consistent association between high hospital volume and lower postoperative mortality rates with improved long-term survival.

Abstract
BACKGROUND To describe variation in staging and primary treatment by hospital characteristics including type and volume and region in patients with early breast cancer (BC) in the Netherlands, 2003-2006 after completion of national guidelines in 2002. METHODS All patients newly diagnosed with invasive BC in 2003-2006 and recorded in the Netherlands Cancer Registry were included (n = 51 354). Multivariable logistic regression analyses examined the influence of patient and hospital characteristics, also by region, on type of breast surgery, axillary lymph node dissection (ALND), sentinel node procedure (SNP), and adjuvant irradiation and/or systemic treatment. RESULTS Patients <40 years more often underwent breast conserving surgery (BCS) in general hospitals (OR 1.4 (95%CI 1.1-1.5)) than in teaching and academic hospitals, whereas patients of 40-69 years less often received BCS in an academic hospital (OR 0.9 (95%CI 0.8-1.0)) than in teaching hospitals. Patients with pT1-2N0 cancer more often underwent primary ALND in a general hospital than in a larger teaching or academic hospital. Type of hospital did not seem to affect utilization of adjuvant systemic therapy, but patient age and tumour size and grade did. Over time, patients more often received SNP, BCS, and adjuvant systemic therapy, primary ALND being on the decline, but with substantial regional variation between geographic regions. CONCLUSION With detailed evidence-based national guidelines since 2002 the considerable regional and hospital variation in staging procedures and primary treatment among newly diagnosed patients with early breast cancer in the Netherlands decreased markedly, suggesting the presence of late adaptors rather than specific hospital characteristics.

Abstract
BACKGROUND Aim of this study was to describe treatment patterns and outcome according to region and hospital type and volume among patients with rectal cancer in the Netherlands. METHODS All patients with rectal carcinoma diagnosed in the period 2001-2006 were selected from the Netherlands Cancer Registry. Logistic regression analyses were performed to examine the influence of relevant factors on the odds of receiving preoperative radiotherapy and on the odds of postoperative mortality. Relative survival analysis was used to estimate relative excess risk of dying according to hospital type and volume. RESULTS In total, 16 039 patients were selected. Patients diagnosed in a teaching or university hospital had a lower odds (OR 0.85; 95% CI 0.73-0.99 and OR 0.70; 95% CI 0.52-0.92) and patients diagnosed in a hospital performing >50 resections per year had a higher odds (OR 1.95; 95% CI 1.09-1.76) of receiving preoperative radiotherapy. A large variation between individual hospitals in rates of preoperative radiotherapy and between Comprehensive Cancer Centre-regions in the administration of preoperative chemoradiation was revealed. Postoperative mortality was not correlated to hospital type or volume. Patients with T1-M0 tumours diagnosed in a hospital with >50 resections per year had a better survival compared to patients diagnosed in a hospital with <25 resections per year (RER 0.11; 95% CI 0.02-0.78). CONCLUSION This study demonstrated variation in treatment and outcome of patients with rectal cancer in the Netherlands, with differences related to hospital volume and hospitals teaching or academic status. However, variation in treatment patterns between individual hospitals proved to be much larger than could be explained by the investigated characteristics. Future studies should focus on the reasons behind these differences, which could lead to a higher proportion of patients receiving optimal treatment for their stage of the disease.
