Abstract
BACKGROUND In the Netherlands, use of neoadjuvant radiotherapy for rectal cancer declined after guideline revision in 2014. This decline is thought to affect the clinical nature and treatability of locally recurrent rectal cancer (LRRC). Therefore, this study compared two national cross-sectional cohorts before and after the guideline revision with the aim to determine the changes in treatment and survival of LRRC patients over time. METHODS Patients who underwent resection of primary rectal cancer in 2011 (n = 2094) and 2016 (n = 2855) from two nationwide cohorts with a 4-year follow up were included. Main outcomes included time to LRRC, synchronous metastases at time of LRRC diagnosis, intention of treatment and 2-year overall survival after LRRC. RESULTS Use of neoadjuvant (chemo)radiotherapy for the primary tumour decreased from 88.5% to 60.0% from 2011 to 2016. The 3-year LRRC rate was not significantly different with 5.1% in 2011 (n = 114, median time to LRRC 16 months) and 6.3% in 2016 (n = 202, median time to LRRC 16 months). Synchronous metastasis rate did not significantly differ (27.2% vs 33.7%, p = 0.257). Treatment intent of the LRRC shifted towards more curative treatment (30.4% vs. 47.0%, p = 0.009). In the curatively treated group, two-year overall survival after LRRC diagnoses increased from 47.5% to 78.7% (p = 0.013). CONCLUSION Primary rectal cancer patients in 2016 were treated less often with neoadjuvant (chemo)radiotherapy, while LRRC rates remained similar. Those who developed LRRC were more often candidate for curative intent treatment compared to the 2011 cohort, and survival after curative intent treatment also improved substantially.

Abstract
BACKGROUND Postoperative mortality plays an important role in evaluating the surgical safety of esophagectomy. Although postoperative mortality after esophagectomy is partly influenced by the yearly hospital surgical case volume (hospital volume), this association remains unclear. METHODS Studies assessing the association between hospital volume and postoperative mortality in patients who underwent esophagectomy for esophageal cancer were searched for eligibility. Odds ratios were pooled for the highest versus lowest categories of hospital volume using a random effects model. The dose-response association between hospital volume and the risk of postoperative mortality was analyzed. The study protocol was registered with PROSPERO. RESULTS Fifty-six studies including 385 469 participants were included. A higher-volume hospital significantly reduced the risk of postesophagectomy mortality by 53% compared with their lower-volume counterparts (odds ratio, 0.47; 95% CI: 0.42-0.53). Similar results were found in subgroup analyses. Volume-outcome analysis suggested that postesophagectomy mortality rates remained roughly stable after the hospital volume reached a plateau of 45 esophagectomies per year. CONCLUSIONS Higher-volume hospitals had significantly lower postesophagectomy mortality rates in patients with esophageal cancer, with a threshold of 45 esophagectomies per year for a high-volume hospital. This remarkable negative correlation showed the benefit of a better safety in centralization of esophagectomy to a high-volume hospital.

Abstract
OBJECTIVE To identify the factors associated with readmission after pancreatectomy for cancer and to assess their impact on the 1-year mortality in a French multicentric population. BACKGROUND Pancreatectomy is a complex procedure with high morbidity that increases the length of hospital stay and jeopardizes survival. Hospital readmissions lead to increased health system costs, making this a topic of great interest. METHODS Data collected from patients who underwent pancreatectomy for cancer between 2011 and 2019 were extracted from a French national medico-administrative database. A descriptive analysis was conducted to evaluate the association of baseline variables, including age, sex, liver-related comorbidities, Charlson Comorbidity Index, tumor localization, and use of neoadjuvant therapy, along with hospital type and volume, with readmission status. Centers were divided into low and high volumes according to the cutoff of 26 cases/year. Logistic regression models were developed to determine whether the identified bivariate associations persisted after adjusting for the patient characteristics. The mortality rates during readmission and at 1 year postoperatively were also determined. RESULTS Of 22,935 patients who underwent pancreatectomy, 9129 (39.3%) were readmitted within 6 months. Readmission rates by year did not vary over the study period, and mean readmissions occurred within 20 days after discharge. Multivariate analysis showed that male sex [odds ratio (OR) = 1.12], age >70 years (OR = 1.16), comorbidities (OR = 1.21), distal pancreatectomy (OR = 1.11), and major postoperative complications (OR = 1.37) were predictors of readmission. Interestingly, readmission and surgery in low-volume centers increased the risk of death at 1 year by a factor of 2.15 [(2.01-2.31), P < 0.001] and 1.31 [(1.17-1.47), P < 0.001], respectively. CONCLUSIONS Readmission after pancreatectomy for cancer is high with an increased rate of 1-year mortality.

Abstract
BACKGROUND Complex surgical care is often centralized to one high volume (hub) hospital within a system. The benefit of this centralization in common operations is unknown. METHODS Using the Healthcare Cost and Utilization Project's State Inpatient Databases, adult general surgical patients within hospital systems in 13 states (2016-2018) were identified. Risk-adjusted logistic regression estimated the odds of death or serious morbidity (DSM) and prolonged length of stay (LOS) at hubs relative to other system hospitals (spokes). RESULTS We identified 122,895 patients across 43 hub-and-spoke systems. Hubs completed 83.2 % of complex and 59.6 % of common operations. For complex operations, odds of DSM were significantly lower in hubs (OR: 0.80; 95 % CI [0.65, 0.98]). For common operations, odds of DSM were similar between hubs and spokes, while odds of prolonged LOS were greater at hubs (OR 1.19; 95 % CI [1.16,1.24]). CONCLUSIONS While hub hospitals had lower odds of DSM for complex operation, they had higher odds of prolonged length of stay for common operations. This finding shows an opportunity for improved system efficiency.

Fragmentation of Care in Patients with Peritoneal Metastases Undergoing Cytoreductive Surgery. Ann Surg Oncol 2024; 31:645-654. [PMID: 37737968 DOI: 10.1245/s10434-023-14318-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 09/05/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND The delivery of multimodal treatment at a high-volume center is known to optimize the outcomes of gastrointestinal malignancies. However, patients undergoing cytoreductive surgery (CRS) for peritoneal metastases often must 'fragment' their surgical and systemic therapeutic care between different institutions. We hypothesized that this adversely affects outcomes. PATIENTS AND METHODS Adults undergoing CRS for colorectal or appendiceal adenocarcinoma at our institution between 2016 and 2022 were identified retrospectively and grouped by care network: 'coordinated care' patients received exclusively in-network systemic therapy, while 'fragmented care' patients received some systemic therapy from outside-network providers. Factors associated with fragmented care were also ascertained. Overall survival (OS) from CRS and systemic therapy-related serious adverse events (SAEs) were compared across the groups. RESULTS Among 85 (80%) patients, 47 (55%) had colorectal primaries and 51 (60%) received fragmented care. Greater travel distance [OR 1.01 (CI 1.00-1.02), p = 0.02] and educational status [OR 1.04 (CI 1.01-1.07), p = 0.01] were associated with receiving fragmented care. OS was comparable between patients who received fragmented and coordinated care in the colorectal [32.5 months versus 40.8 months, HR 0.95 (CI 0.43-2.10), p = 0.89] and appendiceal [31.0 months versus 27.4 months, HR 1.17 (CI 0.37-3.74), p = 0.55] subgroups. The frequency of SAEs (7.8% versus 17.6%, p = 0.19) was also similar. CONCLUSIONS There were no significant differences in survival or SAEs based on the networks of systemic therapy delivery. This suggests that patients undergoing CRS at a high-volume center may safely receive systemic therapy at outside-network facilities with comparable outcomes.

Abstract
OBJECTIVE To determine the threshold annualized esophagectomy volume that is associated with improved survival, oncologic resection, and postoperative outcomes. BACKGROUND Esophagectomy at high-volume centers is associated with improved outcomes; however, the definition of high-volume remains debated. METHODS The 2004 to 2016 National Cancer Database was queried for patients with clinical stage I to III esophageal cancer undergoing esophagectomy. Center esophagectomy volume was modeled as a continuous variable using restricted cubic splines. Maximally selected ranks were used to identify an inflection point of center volume and survival. Survival was compared using multivariable Cox proportional hazards methods. Multivariable logistic regression was used to examine secondary outcomes. RESULTS Overall, 13,493 patients met study criteria. Median center esophagectomy volume was 8.2 (interquartile range: 3.2-17.2) cases per year. On restricted cubic splines, inflection points were identified at 9 and 30 cases per year. A multivariable Cox model was constructed modeling annualized center surgical volume as a continuous variable using 3 linear splines and inflection points at 9 and 30 cases per year. On multivariable analysis, increasing center volume up to 9 cases per year was associated with a substantial survival benefit (hazard ratio: 0.97, 95% confidence interval, 0.95-0.98, P ≤0.001). On multivariable logistic regression, factors associated with undergoing surgery at a high-volume center (>9 cases per year) included private insurance, care at an academic center, completion of high school education, and greater travel distance. CONCLUSIONS This National Cancer Database study utilizing multivariable analysis and restricted cubic splines suggests the threshold definition of a high-volume esophagectomy center as one that performs at least 10 operations a year.

Abstract
BACKGROUND Centralization of pancreatic cancer surgery aims to improve postoperative outcomes. Consequently, patients with pancreatic cancer may undergo pancreatic surgery in an expert centre and adjuvant chemotherapy in a local hospital (network treatment). The aim of this study was to assess whether network treatment has an impact on time to chemotherapy, failure to complete adjuvant chemotherapy, and survival. Second, whether these parameters varied between pancreatic networks was studied. METHODS This retrospective study included all patients diagnosed with non-metastatic pancreatic ductal adenocarcinoma who underwent pancreatic surgery and adjuvant chemotherapy, registered in the Netherlands Cancer Registry (2015-2020). Time to chemotherapy was defined as the time between surgery and the start of adjuvant chemotherapy. Completion of adjuvant chemotherapy was defined as the receipt of 12 cycles of FOLFIRINOX or six cycles of gemcitabine. Analysis was performed with linear mixed models and multilevel logistic regression models. Cox regression analyses were performed for survival. RESULTS In total, 1074 patients were included. Network treatment was observed in 468 patients (43.6 per cent) and was not associated with longer time to chemotherapy (0.77 days, standard error (s.e.) 1.14, P = 0.501), failure to complete adjuvant chemotherapy (odds ratio (OR) = 1.140, 95 per cent c.i. 0.86 to 1.52, P = 0.349), and overall survival (hazards ratio (HR) = 1.04, 95 per cent c.i. 0.88 to 1.22, P = 0.640). Significant variation between the networks was observed for time to chemotherapy (range 40.5-63 days, P < 0.0001) and completion of adjuvant chemotherapy (range 19-52 per cent, P = 0.030). Adjusted for case mix, time to chemotherapy significantly differed between networks. CONCLUSION In this nationwide analysis, network treatment in patients with resected pancreatic cancer was not associated with longer time to chemotherapy, failure to complete adjuvant chemotherapy, and worse survival. Significant variation between pancreatic cancer networks was found for time to chemotherapy.

A Population-Based Study Using Belgian Cancer Registry Data Supports Centralization of Esophageal Cancer Surgery in Belgium. Ann Surg Oncol 2023; 30:1545-1553.

Abstract
BACKGROUND Esophageal cancer surgery outcomes benefit from higher hospital volumes. Despite the evidence, organization of national health care often is complex and depends on various factors. The volume-outcome results of this population-based study supported national health policy measures regarding concentration of esophageal resections in Belgium. METHODS The Belgian Cancer Registry (BCR) database was linked to administrative data on cancer treatment. All Belgian patients with newly diagnosed esophageal cancer in 2008-2018 undergoing resection were allocated to the hospital at which surgery was performed. The study assessed hospital volume association with 90-day mortality and 5-year overall survival, classifying average annual hospital volume of resections as low (LV, <6), medium (MV, 6-19), or high (HV, ≥20) and as a continuous covariate in the regression models. RESULTS The study included 4156 patients who had surgery in 79 hospitals (2 HV hospitals [37% of all surgeries], 12 MV hospitals [30% of all surgeries], and 65 LV hospitals [33% of all surgeries]). Adjusted 90-day mortality in HV hospitals was lower than in LV hospitals (odds ratio [OR], 0.37; 95% CI, 0.21-0.65; p = 0.001). Case-mix adjusted 5-year survival was superior in HV versus LV (hazard ratio [HR], 0.43; 95% CI, 0.31-0.60; p < 0.001). The continuous model demonstrated a lower 90-day mortality (OR, 0.40; 95% CI, 0.23-0.71; p = 0.002) and a superior 5-year survival (HR, 0.45; 95% CI, 0.33-0.63; p < 0.001) in hospitals with volumes of 40 or more resections annually. CONCLUSION Population-based data from the BCR confirmed a strong volume-outcome association for esophageal resections. Improved 5-year survival in centers with annual volumes of 20 or more resections was driven mainly by the achievement of superior 90-day mortality. These findings supported centralization of esophageal resections in Belgium.

Effect of Thoracic Surgery Regionalization on 1- and 3-Year Survival after Cancer Esophagectomy. Ann Surg 2023; 277:e305-e312. [PMID: 34261883 DOI: 10.1097/sla.0000000000005076] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/08/2023]
Abstract
OBJECTIVE The aim of this study was to investigate whether our previously reported improvements in short-term cancer esophagectomy outcomes after large-scale regionalization in the United States translated to longer-term survival benefit. BACKGROUND Regionalization is associated with better early postoperative outcomes following cancer esophagectomy; however, data regarding its effect on long-term survival are mixed. METHODS We retrospectively reviewed 461 patients undergoing cancer esophagectomy before (2009-2013, N = 272) and after (2014-2016, N = 189) regionalization. Kaplan-Meier curves and chi-square tests were used to describe 1- and 3-year survival in each era. Hierarchical logistic regression models examined the adjusted effect of regionalization on mortality. RESULTS Compared to pre-regionalization patients, post-regionalization patients had significantly higher 1-year survival (83.1% vs 73.9%, P = 0.02) but not 3-year survival (52.9% vs 58.2%, P = 0.26).Subgroup analysis by cancer stage revealed that 1-year survival benefit was only significant among mid-stage (IIB-IIIB) patients, whereas differences in 3-year survival only approached significance among early-stage (IA-IIA) patients.In multivariable analysis, only regionalization was a predictor of lower mortality at 1 year [odds ratio (OR) 0.54, 95% confidence interval (CI) 0.29-1.00], and only thoracic specialty at 3years (OR 0.62, 95% CI 0.38-0.99). Older age, more advanced stage, and complications were associated with higher 1- and 3-year mortality. Comorbidity, minimally invasive approach, surgeon volume, facility volume, and neoadjuvant treatment were not significant in this model. CONCLUSIONS Regionalization was associated with improved 1-year survival after cancer esophagectomy, independent of factors such as morbidity or volume in our adjusted models. This survival benefit did not persist at 3 years, likely due to the aggressive nature of the disease.

Abstract
Data management in transmural care is complex. Without digital innovations like Health Information Exchange (HIE), patient information is often dispersed and inaccessible across health information systems between hospitals. The extent of information loss and consequences remain unclear. We aimed to quantify patient information availability of referred oncological patients and to assess its impact on unnecessary repeat diagnostics by observing all oncological multidisciplinary team meetings (MDTs) in a tertiary hospital. During 84 multidisciplinary team meetings, 165 patients were included. Complete patient information was provided in 17.6% (29/165, CI = 12.3-24.4) of patients. Diagnostic imaging was shared completely in 52.5% (74/141, CI = 43.9-60.9), imaging reports in 77.5% (100/129, CI = 69.2-84.2), laboratory results in 55.2% (91/165, CI = 47.2-62.8), ancillary test reports in 58.0% (29/50, CI = 43.3-71.5), and pathology reports in 60.0% (57/95, CI = 49.4-69.8). A total of 266 tests were performed additionally, with the main motivation not previously performed followed by inconclusive or insufficient quality of previous tests. Diagnostics were repeated unnecessarily in 15.8% (26/165, CI = 10.7-22.4) of patients. In conclusion, patient information was provided incompletely in majority of referrals discussed in oncological multidisciplinary team meetings and led to unnecessary repeat diagnostics in a small number of patients. Additional research is needed to determine the benefit of Health Information Exchange to improve data transfer in oncological care.

Defining Facility Volume Threshold for Optimization of Short- and Long-Term Outcomes in Patients Undergoing Resection of Perihilar Cholangiocarcinoma. J Gastrointest Surg 2022; 27:730-740. [PMID: 36138311 DOI: 10.1007/s11605-022-05465-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/10/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND We determined the minimum threshold (Tmin) of annual facility case volume to optimize outcomes for patients with resected perihilar cholangiocarcinoma. METHODS We identified patients with localized perihilar cholangiocarcinoma who underwent resection within the National Cancer Database (2010-2017). We used marginal structural logistic regression models to estimate the average treatment effect of receiving care in facilities meeting/exceeding Tmin on 90-day mortality and other postoperative outcomes. RESULTS A total of 2471 patients underwent resection for perihilar cholangiocarcinoma at 471 facilities. There was no effect of total hepatopancreatobiliary, surgical hepatopancreatobiliary, total hepatobiliary, surgical hepatobiliary, or total perihilar cholangiocarcinoma case volume on 90-day mortality. A Tmin of seven perihilar cholangiocarcinoma resections/year resulted in lower odds of 90-day mortality (IP-weighted OR = 0.49, 95% CI: 0.66-0.87). A total of two facilities met the Tmin. Patients receiving treatment at Tmin facilities had lower odds of length of stay ≥ 7 days (IP-weighted OR = 0.85, 95% CI: 0.75-0.97) and positive surgical resection margins (IP-weighted OR = 0.40, 95% CI: 0.47-0.55). Additionally, undergoing surgery at Tmin facilities resulted in higher (≥ 4 nodes) lymph node yields (IP-weighted OR = 1.94, 95% CI: 1.21-3.11) but no change in the odds of nodal positivity. There was no effect of undergoing surgery at Tmin facilities on 30-day mortality or re-admission. CONCLUSIONS Resection of perihilar cholangiocarcinoma is infrequently performed at a high number of facilities. A Tmin of ≥ 7 resections/year resulted in lower 90-day mortality and improved postoperative outcomes. Our data suggest that regionalization of care for patients with perihilar cholangiocarcinoma could potentially improve outcomes in the USA.

Abstract
BACKGROUND Data on the age-specific incidence of esophageal cancer are lacking. Our aim was to investigate the age-stratified incidence, treatment, and survival trends of esophageal cancer in the Netherlands, with a focus on adults <50 years. MATERIAL AND METHODS Patients diagnosed with esophageal cancer were included from the nationwide Netherlands Cancer Registry (1989-2018). Follow-up data were available until 31 December 2018. Annual percentage changes of incidence were analyzed according to age group (<50, 50-74, and ≥75 years) and histology type: adenocarcinoma (EAC) and squamous cell carcinoma (ESCC). Treatment trends and relative survival rates (RSR) were estimated by age and stage grouping. RESULTS A total 59,584 patients were included. In adults <50 years, EAC incidence tripled (mean increase per year: males 1.5%, females 3%), while the incidence of ESCC decreased (mean decrease per year: males -5.3%, females -4.3%). Patients <50 years more often presented with advanced disease stages compared to older patients and were more likely to receive multimodality treatments. Most patients <50 years with potentially curable disease were treated with neoadjuvant chemoradiotherapy followed by surgery compared to patients 50-74 and ≥75 years (74% vs. 55% vs. 15%, respectively; p < .001), and received more frequent systemic therapy once staged with palliative disease (72% vs. 54% vs. 19%, respectively; p < .001). The largest RSR improvement was seen in patients <50 years with early-stage (five years: +47%), potentially curable (five years: +22%), and palliative disease (one year: +11%). Over time, a trend of increasing survival difference was seen between patients <50 and ≥75 years with potentially curable (five-year difference: 17% to 27%) and palliative disease (one-year difference: 11% to 20%). CONCLUSION The incidence of EAC is increasing in adults <50 years in the Netherlands. Differences in the use of multimodality treatments with curative or life-prolonging intent in different age categories may account for increasing survival gaps.

Wirth K, Näpflin M, Graber SM, Blozik E. Does hospital volume affect outcomes after abdominal cancer surgery: an analysis of Swiss health insurance claims data. BMC Health Serv Res 2022; 22:262. [PMID: 35219332 PMCID: PMC8881861 DOI: 10.1186/s12913-022-07513-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 01/13/2022] [Indexed: 11/10/2022] Open
Abstract
Background Medical treatment quality has been shown to be better in high volume than in low volume hospitals. However, this relationship has not yet been confirmed in abdominal cancer in Switzerland and is relevant for referral of patients and healthcare planning. Thus, the present study investigates the association between hospital volumes for surgical resections of colon, gastric, rectal, and pancreatic carcinomas and outcomes. Methods This retrospective analysis is based on anonymized claims data of patients with mandatory health insurance at Helsana Group, a leading health insurance in Switzerland. Outcome parameters were length of hospital stay, mortality and cost during the inpatient stay as well as at 1-year follow-up. Hospital volume information was derived from the Quality Indicators dataset provided by the Swiss Federal Office of Public Health. The impact of hospital volume on the different treatment outcomes was statistically tested using generalized estimating equations (GEE) models, taking into account the non-independence of observations from the same hospital. Results The studies included 2′859 resections in patients aged 18 years and older who were hospitalized for abdominal cancer surgery between 2014 and 2018. Colon resections were the most common procedures (n = 1′690), followed by rectal resections (n = 709). For rectal, colon and pancreatic resections, an increase in the mean number of interventions per hospital and a reduction of low volume hospitals could be observed. For the relationship between hospital volume and outcomes, we did not observe a clear dose-response relationship, as no significantly better outcomes were observed in the higher-volume category than in the lower-volume category. Even though a positive “routine effect” cannot be excluded, our results suggest that even hospitals with low volumes are able to achieve comparable treatment outcomes to larger hospitals. Conclusion In summary, this study increases transparency on the relationship between hospital volume and treatment success. It shows that simple measures such as defining a minimum number of procedures only might not lead to the intended effects if other factors such as infrastructure, the operating team or aggregation level of the available data are not taken into account.

Long-term effect of hospital volume on the postoperative prognosis of 158,618 patients with esophageal squamous cell carcinoma in China. Front Oncol 2022; 12:1056086.

Abstract
Background The impact of hospital volume on the long-term survival of esophageal squamous cell carcinoma (ESCC) has not been well assessed in China, especially for stage I-III stage ESCC. We performed a large sample size study to assess the relationships between hospital volume and the effectiveness of ESCC treatment and the hospital volume value at the lowest risk of all-cause mortality after esophagectomy in China. Aim To investigate the prognostic value of hospital volume for assessing postoperative long-term survival of ESCC patients in China. Methods The date of 158,618 patients with ESCC were collected from a database (1973-2020) established by the State Key Laboratory for Esophageal Cancer Prevention and Treatment, the database includes 500,000 patients with detailed clinical information of pathological diagnosis and staging, treatment approaches and survival follow-up for esophageal and gastric cardia cancers. Intergroup comparisons of patient and treatment characteristics were conducted with the X2 test and analysis of variance. The Kaplan-Meier method with the log-rank test was used to draw the survival curves for the variables tested. A Multivariate Cox proportional hazards regression model was used to analyze the independent prognostic factors for overall survival. The relationship between hospital volume and all-cause mortality was assessed using restricted cubic splines from Cox proportional hazards models. The primary outcome was all-cause mortality. Results In both 1973-1996 and 1997-2020, patients with stage I-III stage ESCC who underwent surgery in high volume hospitals had better survival than those who underwent surgery in low volume hospitals (both P<0.05). And high volume hospital was an independent factor for better prognosis in ESCC patients. The relationship between hospital volume and the risk of all-cause mortality was half-U-shaped, but overall, hospital volume was a protective factor for esophageal cancer patients after surgery (HR<1). The concentration of hospital volume associated with the lowest risk of all-cause mortality was 1027 cases/year in the overall enrolled patients. Conclusion Hospital volume can be used as an indicator to predict the postoperative survival of ESCC patients. Our results suggest that the centralized management of esophageal cancer surgery is meaningful to improve the survival of ESCC patients in China, but the hospital volume should preferably not be higher than 1027 cases/year. Core tip Hospital volume is considered to be a prognostic factor for many complex diseases. However, the impact of hospital volume on long-term survival after esophagectomy has not been well evaluated in China. Based on a large sample size of 158,618 ESCC patients in China spanning 47 years (1973-2020), We found that hospital volume can be used as a predictor of postoperative survival in patients with ESCC, and identified hospital volume thresholds with the lowest risk of death from all causes. This may provide an important basis for patients to choose hospitals and have a significant impact on the centralized management of hospital surgery.

Exploring the concept of centralization of surgery for benign esophageal diseases: a Delphi based consensus from the European Society for Diseases of the Esophagus. Dis Esophagus 2021; 34:6148804. [PMID: 33621318 DOI: 10.1093/dote/doab013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 01/22/2021] [Accepted: 02/02/2021] [Indexed: 12/11/2022]
Abstract
Surgery for benign esophageal diseases may be complex, requiring specialist training, but currently, unlike oncologic surgery, it is not centralized. The aim of the study was to explore the opinion of European surgeons on the centralization of surgery for benign esophageal diseases. A web-based questionnaire, developed through a modified Delphi process, was administered to general and thoracic surgeons of 33 European surgical societies. There were 791 complete responses (98.5%), in 59.2% of respondents, the age ranged between 41 and 60 years, 60.3% of respondents worked in tertiary centers. In 2017, the number of major surgical procedures performed for any esophageal disease by respondents was <10 for 56.5% and >100 for 4.5%; in responder's hospitals procedures number was <10 in 27% and >100 in 15%. Centralization of surgery for benign esophageal diseases was advocated by 83.4%, in centers located according to geographic/population criteria (69.3%), in tertiary hospitals (74.5%), with availability of advanced diagnostic and interventional technologies (88.4%), in at least 10 beds units (70.5%). For national and international centers accreditation/certification, criteria approved included in-hospital mortality and morbidity (95%), quality of life oriented follow-up after surgery (88.9%), quality audits (82.6%), academic research (58.2%), and collaboration with national and international centers (76.6%); indications on surgical procedures volumes were variable. The present study strongly supports the centralization of surgery for benign esophageal diseases, in large part modeled on the principles that have underpinned the centralization of cancer surgery internationally, with emphasis on structure, process, volumes, quality audit, and clinical research.

Abstract
OBJECTIVE This study investigated the influence of facility volume on long-term survival in patients with esophageal cancer treated with esophagectomy. METHODS Patients treated with esophagectomy for cT1 3N0 3M0 adenocarcinoma or squamous cell carcinoma of the mid-distal esophagus in the National Cancer Database between 2006 and 2013 were stratified by annual facility esophagectomy volume dichotomized as more/less than both 6 and 20. Patient characteristics associated with facility volume were evaluated using logistic regression, and the influence of facility volume on survival was evaluated with Kaplan-Meier curves, Cox proportional hazards methods, and propensity matched analysis. RESULTS Of 11,739 patients who had esophagectomy at 1018 facilities where annual volume ranged from 1 to 47.6 cases, 4262 (36.3%) were treated at 44 facilities with annual esophagectomy volume > 6 and 1515 (12.9%) were treated at 7 facilities with annual volume > 20. Higher volume was associated with significantly better 5-year survival for both annual volume > 6 (47.6% vs 40.2%; P < .001) and annual volume > 20 (47.2% vs 42.3%; P < .001), which persisted in propensity matched analyses as well as Cox multivariable analysis (hazard ratio, 0.81; 95% confidence interval, 0.74-0.89; P < .001 for facility volume > 6 and hazard ratio, 0.78; 95% confidence interval, 0.65-0.95; P = .01 for facility volume > 20). In Cox multivariable analysis that considered facility volume as a continuous variable, higher volume continued to be associated with better survival (hazard ratio, 0.93 per 5 cases; 95% CI, 0.91-0.96; P < .001). CONCLUSIONS Esophageal cancer patients treated with esophagectomy at higher volume facilities have significantly better long-term survival than patients treated at lower volume facilities.

Abstract
To perform a systematic review of studies prospectively analyzing the impact of regionalization of complex surgical oncology care on patient outcomes. High volume care of complex surgical oncology patients has been repeatedly associated with improved outcomes. Most studies, however, are retrospective and have not prospectively accounted for confounders such as financial ability and social support. Four electronic databases (Ovid MEDLINE®, Ovid EMBASE, Cochrane Library (Wiley), and EBSCHOHost) were searched from inception until August 25, 2018. Two authors independently reviewed 5887 references, with a third independent reviewer acting as arbitrator when needed. Data extracted from 11 articles that met inclusion criteria. Risk of bias assessments conducted using MINORS criteria for the non-randomized, observational studies, and the Cochrane tool for the randomized-controlled trial. Of the 11 studies selected, we found 7 historically-controlled trials, two retrospective cohort studies with prospective data collection, one prospective study, and one randomized-controlled trial. 73% of studies were from Northern Europe, 18% from Ontario, Canada, and 9% from England. Pancreatic surgery accounted for 36% of studies, followed by gynecologic oncology (27%), thoracic surgery (18%), and dermatologic surgery (9%). The studies reported varying outcome parameters, but all showed improvement post-regionalization. Included studies featured poor-to-fair risk of bias. 11 studies indicated improved outcomes following regionalization of surgical oncology, but most exhibit poor methodological rigor. Prospective evidence for the regionalization of surgical oncology is lacking. More research addressing patient access to care and specialist availability is needed to understand the shortcomings of centralization.

Abstract
OBJECTIVES To review the evidence of the effects of centralization of cancer surgery on postoperative mortality. METHODS We searched Medline, Embase, Cinahl, Cochrane and Scopus (up to November 2019) for studies that (i) assessed the effects of centralization of cancer surgery policies on in-hospital or 30-day mortality, or (ii) described changes in both postoperative mortality for a surgical intervention and degree of centralization using reduction in the number of hospitals or increases in the proportion of patients undergoing cancer surgery at high volume hospitals as proxy. PRISMA guidelines were followed. We estimated pooled odds ratios (OR) and conducted meta-regression to assess the relationship between degree of centralization and mortality. RESULTS A total of 41 studies met our inclusion criteria of which 15 evaluated the effect of centralization policies on postoperative mortality after cancer surgery and 26 described concurrent changes in the degree of centralization and postoperative mortality. Policy evaluation studies mainly used before-after designs (n = 13) or interrupted time series analysis (n = 2), mainly focusing on pancreatic, oesophageal and gastric cancer. All but one showed some degree of reduction in postoperative mortality, with statistically significant effects demonstrated by six studies. The pooled odds ratio for centralization policy effect was 0.68 (95% Confidence interval: 0.54-0.85; I2 = 80%). Meta-regression analysis of the 26 descriptive studies found that an increase of the proportion of patients treated at high volume hospitals was associated with greater reduction in postoperative mortality. CONCLUSIONS Centralization of cancer surgery is associated with reduced postoperative mortality. However, existing evidence tends to be of low quality and estimates of the effect size are likely inflated. There is a need for prospective studies using more robust approaches, and for centralization efforts to be accompanied by well-designed evaluations of their effectiveness.

Am J Obstet Gynecol 2021; 224:274.e1-274.e10.

Abstract
BACKGROUND In June 2013, Ontario Health (Cancer Care Ontario), the agency responsible for advancing cancer care in Ontario, Canada, published practice guidelines recommending that gynecologic oncologists at tertiary care centers manage the treatment of patients with high-grade endometrial cancers. This study examines the effects of this regionalization of care on patient outcomes. OBJECTIVE This study aimed to evaluate the impact of the regionalization of surgery for high-grade endometrial cancer on patient and treatment outcomes. STUDY DESIGN In this retrospective cohort study, patients diagnosed with nonendometrioid high-grade endometrial cancer from 2003 to 2017 were identified using province-wide administrative databases. To allow 6 months for knowledge translation, 2 periods were defined, with January 1, 2014, as the cutoff. Methods for segmented regression were used to test the effect of the guidelines. Multivariable Cox proportional hazards regression was used to evaluate whether regionalization of care had an impact on patient survival. RESULTS There were 3518 patients with nonendometrioid high-grade endometrial cancer identified. The case mix as represented by patient comorbidities and the disease stage distribution did not differ significantly between the 2 regionalization periods. There was a significant increase (69%-85%; P<.001) in the proportion of primary surgeries performed by gynecologic oncologists after regionalization, which was not explained by secular trends. After regionalization, the proportion of patients who had surgical staging (50%-63%; P<.001) and the proportion of patients who received adjuvant treatment (65%-71%; P<.001) increased significantly. After adjusting for age, stage, and comorbidities, there was a decrease in the hazard of mortality (hazard ratio, 0.85 [95% confidence interval, 0.73-0.99]; P=.04) after regionalization. CONCLUSION The publication of a regionalization policy for the treatment of high-grade endometrial cancers in Ontario led to an increase in the proportion of surgeries performed by gynecologic oncologists. This also translated into a significant improvement in patient survival.

Abstract
BACKGROUND Over the last 2 decades, outcomes for oesophageal cancer have improved due to advances in surgical and oncological practice. Optimizing outcomes by centralization of oesophagectomy to high-volume centres has been observed. The aim of this study was to establish if technical and oncological outcomes after oesophagectomy in southern New Zealand are comparable to recent benchmarks. METHODS Consecutive patients undergoing oesophagectomy for cancer and benign pathology at Dunedin Hospital from 1995 to 2019 were prospectively audited. For malignant cases, histology was obtained retrospectively along with details of neo-adjuvant and adjuvant therapy. The primary outcome was disease-specific survival, stratified by time, resection margin, and TNM staging. Secondary outcomes included mortality and morbidity of oesophagectomy. Complications were graded using the Clavien-Dindo classification. RESULTS Oesophagectomy was performed in 108 patients, and 99 patients had surgery for oesophageal malignancy. The median survival was 35.3 (95% confidence interval (CI) 30.0-93.4) months and the 5-year survival overall was 41.7%. Comparing survival in patients undergoing oesophagectomy up to 2006 and afterwards showed an improvement in 5-year survival (30.3%, 95% CI (14.2-60.0) versus 47.8%, 95% CI (32.5, not reached), respectively, P = 0.041). There were two perioperative deaths (1.8%), six clinical anastomotic leaks (5.5%), four anastomotic strictures (3.7%) and five chylothoraces (4.6%). CONCLUSION This 25-year survey of oesophagectomy in southern New Zealand audits the results of a low volume centre, where a variety of neo-adjuvant treatments have been used. Despite this, perioperative morbidity, mortality and survival are comparable to those achieved by international high-volume centres.

Abstract
BACKGROUND The in-hospital mortality after visceral surgery in Germany is unknown. METHODS In this retrospective, descriptive analysis, nationwide hospital billing data based on diagnosis-related groups (DRG) over the period 2009-2015 were studied to determine the in-hospital mortality, complications and their management, and deaths after documented severe complications (failure to rescue, FTR) after visceral surgery in Germany. Organ-system subgroups were defined and subdivided into frequent operations (inguinal hernia repair, appendectomy, thyroid operations, cholecystec- tomy), colorectal operations, and complex operations (surgery of the esophagus, pancreas, liver, and stomach). RESULTS 3 287 199 patients from 1392 hospitals were included in the analysis. The in-hospital mortality after visceral surgery was 1.9%. The lowest mortality was after the frequently performed operations (0.04-0.4%), the highest after complex surgery of the esophagus (8.6%) and stomach (11.7%). Severe complications were most commonly seen after complex surgery of the pan- creas (27.7%), liver (24.3%), esophagus (37.8%), and stomach (36.7%). 90.6% of deaths occurred after colorectal or complex operations, which together accounted for 23% of all operations. The FTR rate was 8.4% after appendectomy and cholecystec- tomy (95% confidence interval [8.34; 8.46]) and 20.3% after esophageal surgery ([19.8; 20.8]). CONCLUSION In Germany, in-hospital mortality after visceral surgery is not uncommon, with a frequency of nearly 2%. Improved complication management after complex operations appears necessary. A limitation of this study is the identification of compli- cations from anonymized billing data.

Should all pancreatic surgery be centralized regardless of patients' comorbidity? HPB (Oxford) 2020; 22:1057-1066.

Abstract
BACKGROUND It remains to be established whether centralization to high volume centers is essential for all patients undergoing pancreatic surgery. The aims of this study were to identify the optimal cut-off volume to optimize patient outcomes and to determine if patient comorbidity affected the volume-outcome relationship. METHODS Patients undergoing pancreatectomy from 2012 to 2015 were retrospectively identified (n = 12 333) in the French nationwide database. The 90-day Post-Operative Mortality (POM) was analyzed according to hospital volume of pancreatectomy (very low:<10, Low:10-19, High:20-49 and very high:≥50 resections/year) and Charlson Comorbidity Index (ChCI). RESULTS The overall POM was 6.9%. The cut-off of 20 pancreatic resections per year was identified as predictor of POM. Compared to high volume centers, POM was significantly higher in low and very low volume centers whatever the ChCl. Regarding surgical procedures, there was a significant decrease in POM with increasing hospital volume only after pancreaticoduodenectomy regardless of the ChCl. On multivariable analysis, low and very low volume centers were independently associated with increased mortality rates. CONCLUSION The optimal cut-off of annual caseload was 20 pancreatic resections. POM following pancreaticoduodenectomy is high in low and very low volume centers independently of ChCl, suggesting that this procedure should be centralized.

Abstract
PURPOSE This study was designed to examine the impact of marital status on racial disparities in esophageal cancer care. PATIENTS AND METHODS We performed a secondary analysis of data collected from the state cancer registry maintained by the Michigan Department of Health and Human Services. We identified patients with an esophageal cancer diagnosis between January 1, 2000, and December 31, 2013. χ2 test and logistics regression were used to analyze 6,809 patients who met our eligibility criteria. Statistical significance was defined as P ≤ .05. RESULTS Approximately 88.4% of our patients were White and 11.6% were Black. A significantly higher number of White patients were married when compared with Blacks (62.9% v 31.8%, respectively; P < .0001). There was no significant difference in cancer staging between the 2 groups (P = .0671). Married Blacks had similar rates of esophagectomy, chemotherapy, and radiation as married Whites. Both single groups had lower rates of esophagectomy and chemotherapy than married Whites, but single Blacks were the least likely to undergo esophagectomy. Single patients were more likely to refuse treatment. CONCLUSION Marital status differs significantly in Black and White patients with esophageal cancer and may help explain racial disparities in cancer care. Further research is needed to explore reasons for care underutilization in single patients and whether these differences translate into clinical outcomes.

Abstract
Background Perinatal decision-making affects outcomes for extremely preterm babies (22–26 weeks’ gestational age (GA)): more active units have improved survival without increased morbidity. We hypothesised such units may gain skills and expertise meaning babies at higher gestational ages have better outcomes than if they were born elsewhere. We examined mortality and morbidity outcomes at age two for babies born at 27–28 weeks’ GA in relation to the intensity of perinatal care provided to extremely preterm babies. Methods Fetuses from the 2011 French national prospective EPIPAGE-2 cohort, alive at maternal admission to a level 3 hospital and delivered at 27–28 weeks’ GA, were included. Morbidity-free survival (survival without sensorimotor (blindness, deafness or cerebral palsy) disability) and overall survival at age two were examined. Sensorimotor disability and Ages and Stages Questionnaire (ASQ) result below threshold among survivors were secondary outcomes. Perinatal care intensity level was based on birth hospital, grouped using the ratio of 24–25 weeks’ GA babies admitted to neonatal intensive care to fetuses of the same gestation alive at maternal admission. Sensitivity analyses used ratios based upon antenatal steroids, Caesarean section, and newborn resuscitation. Multiple imputation was used for missing data; hierarchical logistic regression accounted for births nested within centres. Results 633 of 747 fetuses (84.7%) born at 27–28 weeks’ GA survived to age two. There were no differences in survival or morbidity-free survival: respectively, fully adjusted odds ratios were 0.96 (95% CI: 0.54 to 1.71) and 1.09 (95% CI: 0.59 to 2.01) in medium and 1.12 (95% CI: 0.63 to 2.00) and 1.16 (95% CI: 0.62 to 2.16) in high compared to low-intensity hospitals. Among survivors, there were no differences in sensorimotor disability or ASQ below threshold. Sensitivity analyses were consistent with the main results. Conclusions No difference was seen in survival or morbidity-free survival at two years of age among fetuses alive at maternal hospital admission born at 27–28 weeks’ GA, or in sensorimotor disability or presence of an ASQ below threshold among survivors. There is no evidence for an impact of intensity of perinatal care for extremely preterm babies on births at a higher gestational age.

DEUTSCHES ARZTEBLATT INTERNATIONAL 2019; 115:793-800.

Abstract
BACKGROUND In Germany, complex esophageal surgery is often performed in hospitals with low case numbers. For these procedures, an association exists between hospital case numbers and treatment outcomes, possibly because of differences in complication management. This aspect of the association between volume and outcome in esophageal surgery has not yet been studied in Germany. METHODS On the basis of nationwide hospital discharge data (DRG statistics) from the years 2010 to 2015, the association between volume and outcome was analyzed in relation to in-hospital mortality, the frequency of complications, and the mortality of patients who had complications. RESULTS 22 700 cases of complex esophageal surgery were identified. The probability of dying after esophageal surgery was much lower in hospitals with very high case numbers (median, 62 per year) than in those with very low case numbers (median, two per year), with an odds ratio (OR) of 0.50 (95% confidence interval, [0.42; 0.60]). At least one complication was documented for more than half of all patients; no association was found between the frequency of complications and the hospital case volume. The in-hospital mortality among patients who had complications was 12.3% [11.1; 13.7] in hospitals with very high case numbers and 20.0% [18.5; 21.6] in hospitals with very low case numbers. Of the 4032 procedures performed in 2015, 83% were for cancer of the esophagus. CONCLUSION These findings indicate that the quality of care for patients undergoing esophageal surgery in Germany could be improved if more patients were treated in hospitals with high case numbers. The observed association between case numbers and outcomes is tightly linked to failure to rescue.

Abstract
BACKGROUND A retrospective study was performed to characterize trends in centralization of care and compliance with National Comprehensive Cancer Network (NCCN) guidelines for resected cholangiocarcinoma (CCA), and their impact on overall survival (OS). METHODS Using the National Cancer Database (NCDB) 2004-2015 we identified patients undergoing resection for CCA. Receiver Operating Characteristic (ROC) analyses identified time periods and hospital volume groups for comparison. Propensity score matching provided case-mix adjusted patient cohorts. Cox hazard analysis identified risk factors for OS. RESULTS Among the 40,338 patients undergoing resection for CCA, the proportion of patients undergoing surgery at high volume hospitals increased over time (25%-44%, p < 0.001), while the proportion of patients undergoing surgery at low volume hospitals decreased (30%-15%, p < 0.001). Using ROC analyses, a hospital volume of 14 operations/year was the most sensitive and specific value associated with mortality. Surgery at high volume hospitals [HR] = 0.92, 95% CI: 0.88-0.97, p < 0.001) and receipt of care compliant with NCCN guidelines (HR = 0.87, 95% CI: 0.83-0.91, p < 0.001) were independently associated with improved OS. CONCLUSIONS Both centralization of surgery for CCA to high volume hospitals and increased compliance with NCCN guidelines were associated with significant improvements in overall survival.

Abstract
BACKGROUND Despite recent medical advances, surgery remains the mainstay treatment in colon cancer. It is well established that better patient outcomes are achieved when complex surgery including pancreatic, oesophageal and rectal surgeries are carried out in high-volume centres. However, it is unclear as to whether or not colon cancer patients receive the same benefit. Lymph node adequacy is a key performance indicator of successful oncological colonic resection which impacts on patient outcome. AIM To assess the adequacy of lymph node clearance during colonic resection performed with curative intent in a non-specialist centre post introduction of the National Cancer Strategy. METHODS Retrospective analysis was performed of a prospectively maintained database examining the lymph node clearance of all oncological resections for colon cancer over a 7-year period (Nov 2010-Dec 2017) at a satellite unit with links to a regional specialist centre. Primary outcome measured was the number of lymph nodes retrieved. Secondary outcomes included resection margins, 30-day complication rate and survival at 1 year. Statistical analysis was performed using SPSS Statistics for Windows, version 24.0 (IBM Corp, Armonk, N.Y., USA). RESULTS One hundred sixty-seven patients were included. Mean age was 71.0 ± 11.6 years. Majority were male (n = 90, 53.6%). The majority of resections was right sided (n = 112.66.7%) with 78.6% of all resections being undertaken electively. All margins were free of tumour. The average lymph node count was 19.93 ± 8.63 (4.62) with only 17 (10.2%) of specimens containing < 12 nodes. The anastomotic leak rate was 3.3%. There was no association between surgeon or pathologist volume, nor emergent status and achieving oncological lymph node count (p = 0.14, 0.29, 0.97). 90.5% of patients were alive at 1 year. CONCLUSIONS This study demonstrates that colonic cancer surgery can be safely performed in a non- specialist centre with technical outcomes comparable to nationally reported figures.

Abstract
Background Some studies have found that outcomes from cancer esophagectomy are better at higher-volume centers than at lower-volume centers. Reports on outcomes following systematic centralization have largely demonstrated subsequent improvements, but these originate in nationalized healthcare systems that are not very comparable to the heterogeneous private-payer systems that predominate in the United States. We examined how regionalization of thoracic surgery to Centers of Excellence (CoE) within our American integrated healthcare system changed overall care for our patients, and whether it changed outcomes. Methods We conducted a retrospective chart review of 461 consecutive patients undergoing cancer esophagectomy between 2009-2016, spanning the 2014 shift to regionalization. High-volume was defined as ≥5 esophagectomies per year. We compared characteristics of the surgeon, hospital, and operation pre- and post-regionalization using Chi-square or Fisher's exact test for categorical variables and Kruskal-Wallis test for age. We evaluated their associations with patient outcomes with hierarchical linear and logistic mixed models, which adjusted for clustering within surgeon and facility levels and relevant covariates. Results While there was no difference in their baseline demographics, patients undergoing esophagectomy post-regionalization were much more likely to have their surgery performed at a designated Center of Excellence (78.8% of cases versus 34.2%, P<0.001), at a high-volume hospital (92.1% from 75.7%, P<0.001), by a high-volume surgeon (78.8% from 58.8%, P<0.001), by a board-certified thoracic surgeon (82.5% from 64.0%, P<0.001), and by minimally-invasive, versus open, approach (60.8% from 22.1%, P<0.001). Post-regionalization patients were in higher American Society of Anesthesiologists classes (P=0.03) and trended toward higher-stage disease (P=0.14), indicative of the inclusion of higher-complexity patients. Despite that, regionalization was associated with improved short-term outcomes, most notably: average minimally-invasive esophagectomy (MIE) operative time decreased by 2 hours (-135.9 minutes, 95% CI: -172.2, -99.7 minutes); length of stay (LOS) decreased by 2.3 days (95% CI: -3.4, -1.2 days); and 30-day complication rate decreased significantly, from 50.7% to 30.2% (OR 0.45, 95% CI: 0.25, 0.79). Regionalization was the only variable significantly and independently associated with all three outcomes in our adjusted multivariable models. Mortality, both at 30 and 90 days, decreased modestly but was low pre-regionalization, and the difference did not reach significance. Conclusions Regionalization of thoracic surgery in our hospital system resulted in esophagectomies being performed by more experienced surgeons at higher-volume centers, with a concomitant improvement in short-term outcomes. Patients undergoing esophagectomy, particularly MIE, post-regionalization benefited significantly from decreased LOS and perioperative complication rate. Our results suggest that, in a large integrated healthcare system, regionalization significantly improves overall outcomes for patients undergoing cancer esophagectomy.

Abstract
BACKGROUND It is recognised that a limited cohort of patients receive open partial laryngeal surgery in specific centres within the UK, so sharing information around key clinical issues and recommendations for practice is necessary to improve outcomes. METHODS This position statement provides practice recommendations based on a synthesis of the available evidence presented at the 12th Evidence Based Management day on 'Laryngeal Cancer' and the ensuing discussions. Literature searches and critical analysis of available evidence were undertaken and triangulated with the clinical experience of the authors to develop these recommendations.Results and conclusionThis paper presents a comprehensive overview of challenges that the multidisciplinary team may encounter. It provides recommendations for swallow and speech rehabilitation after open partial laryngectomy, and suggests practical ways that these issues may be addressed pre- and post-operatively.

Abstract
OBJECTIVES To investigate whether further centralisation of acute stroke services in Greater Manchester in 2015 was associated with changes in outcomes and whether the effects of centralisation of acute stroke services in London in 2010 were sustained. DESIGN Retrospective analyses of patient level data from the Hospital Episode Statistics (HES) database linked to mortality data from the Office for National Statistics, and the Sentinel Stroke National Audit Programme (SSNAP). SETTING Acute stroke services in Greater Manchester and London, England. PARTICIPANTS 509 182 stroke patients in HES living in urban areas admitted between January 2008 and March 2016; 218 120 stroke patients in SSNAP between April 2013 and March 2016. INTERVENTIONS Hub and spoke models for acute stroke care. MAIN OUTCOME MEASURES Mortality at 90 days after hospital admission; length of acute hospital stay; treatment in a hyperacute stroke unit; 19 evidence based clinical interventions. RESULTS In Greater Manchester, borderline evidence suggested that risk adjusted mortality at 90 days declined overall; a significant decline in mortality was seen among patients treated at a hyperacute stroke unit (difference-in-differences -1.8% (95% confidence interval -3.4 to -0.2)), indicating 69 fewer deaths per year. A significant decline was seen in risk adjusted length of acute hospital stay overall (-1.5 (-2.5 to -0.4) days; P<0.01), indicating 6750 fewer bed days a year. The number of patients treated in a hyperacute stroke unit increased from 39% in 2010-12 to 86% in 2015/16. In London, the 90 day mortality rate was sustained (P>0.05), length of hospital stay declined (P<0.01), and more than 90% of patients were treated in a hyperacute stroke unit. Achievement of evidence based clinical interventions generally remained constant or improved in both areas. CONCLUSIONS Centralised models of acute stroke care, in which all stroke patients receive hyperacute care, can reduce mortality and length of acute hospital stay and improve provision of evidence based clinical interventions. Effects can be sustained over time.

Abstract
Background Gastrectomy with negative resection margins and adequate lymph node dissection is the cornerstone of curative treatment for gastric cancer (gc). However, gastrectomy is a complex and invasive operation with significant morbidity and mortality. Little is known about surgical practice patterns or short- and long-term outcomes in early-stage gc in Canada. Methods We undertook a population-based retrospective cohort study of patients with gc diagnosed between 1 April 2005 and 31 March 2008. Chart review provided clinical and operative details such as disease stage, primary tumour location, surgical approach, operation, lymph nodes, and resection margins. Administrative data provided patient demographics, geography, and vital status. Variations in treatment and outcomes were compared for 14 local health integration networks. Descriptive statistics and log-rank tests were used to examine geographic variation. Results We identified 722 patients with nonmetastatic resected gc. We documented significant provincial variation in case mix, including primary tumour location, stage at diagnosis, and tumour grade. Short-term surgical outcomes varied across the province. The percentage of patients with 15 or fewer lymph nodes removed and examined varied from 41.8% to 73.8% (p = 0.02), and the rate of positive surgical margins ranged from 15.2% to 50.0% (p = 0.002). The 30-day surgical mortality rates did not vary statistically significantly across the province (p = 0.13); however, rates ranged from 0% to 16.7%. Overall 5-year survival was 44% and ranged from 31% to 55% across the province. Conclusions This cohort of patients with resected stages i-iii gc is the largest analyzed in Canada, providing important historical information about treatment outcomes. Understanding the causes of regional variation will support interventions aiming to improve gc operative outcomes in the cancer system.

Abstract
Retinoblastoma-binding protein 7 (RBBP7) is an important component of several complexes that regulate chromatin metabolism. It is overexpressed in certain cancer types and serves conflicting roles in tumor progression. In the present study, the expression and roles of RBBP7 were explored in esophageal squamous cell carcinoma (ESCC). Immunohistochemical staining was used to detect RBBP7 expression in ESCC tissues. The mRNA sequencing profiles from the Cancer Genome Atlas and Genotype-Tissue Expression databases were mined to analyze the mRNA expression of RBBP7 in tissues. Proliferation, clone formation, apoptosis and Transwell invasion/migration assays were performed to explore the roles of RBBP7 in ESCC. RBBP7 was highly expressed in ESCC tissues. The protein and mRNA expression levels of RBBP7 were significantly elevated in tumor tissues compared with paired adjacent normal tissues. RBBP7 overexpression was associated with a poor overall survival in patients with ESCC. Furthermore, higher RBBP7 expression was significantly correlated with poor tumor differentiation, advanced regional lymph node involvement, and pathological TNM staging. Knockdown of RBBP7 in ESCC cells did not affect tumor apoptosis or tumor growth. However, the overexpression of RBBP7 significantly enhanced the invasion and migration of ESCC cells, whereas the knockdown of RBBP7 resulted in significantly decreased invasion and migration. The present study indicated that RBBP7 is a novel biomarker and prognosticator for patients with ESCC. Furthermore, RBBP7 serves crucial roles in promoting ESCC invasion and migration.

Abstract
BACKGROUND Centralization of surgery has been shown to improve outcomes for oesophageal and pancreatic cancer, and has been implemented for gastric cancer since 2012 in the Netherlands. This study evaluated the impact of centralizing gastric cancer surgery on outcomes for all patients with gastric cancer. METHODS Patients diagnosed with non-cardia gastric adenocarcinoma in the intervals 2009-2011 and 2013-2015 were selected from the Netherlands Cancer Registry. Clinicopathological data, treatment characteristics and mortality were assessed for the periods before (2009-2011) and after (2013-2015) centralization. Cox regression analyses were used to assess differences in overall survival between these intervals. RESULTS A total of 7204 patients were included. Resection rates increased slightly from 37·6 per cent before to 39·6 per cent after centralization (P = 0·023). Before centralization, 50·1 per cent of surgically treated patients underwent gastrectomy in hospitals that performed fewer than ten procedures annually, compared with 9·2 per cent after centralization. Patients who had gastrectomy in the second interval were younger and more often underwent total gastrectomy (29·3 per cent before versus 41·2 per cent after centralization). Thirty-day postoperative mortality rates dropped from 6·5 to 4·1 per cent (P = 0·004), and 90-day mortality rates decreased from 10·6 to 7·2 per cent (P = 0·002). Two-year overall survival rates increased from 55·4 to 58·5 per cent among patients who had gastrectomy (P = 0·031) and from 27·1 to 29·6 per cent for all patients (P = 0·003). Improvements remained after adjustment for case mix; however, adjustment for hospital volume attenuated this association for surgically treated patients. CONCLUSION Centralization of gastric cancer surgery was associated with reduced postoperative mortality and improved survival.

Abstract
This article begins by introducing the historical background surrounding the volume-outcomes relationship literature, particularly in complex cancer surgery. The state of evidence surrounding mortality, as well as other outcomes, in relation to both hospital and surgeon procedure volume is synthesized. Where it is understood, the level of adoption of regionalization of various complex surgeries in the United States is also presented. Various controversies are weighed and discussed. Finally, various models of regionalization and proposed alternatives to regionalization from the peer-reviewed literature are presented.

Abstract
BACKGROUND To improve quality of care, centralisation of cancer services in high-volume centres has been stimulated. Studies linking specialisation and high (surgical) volumes to better outcomes already appeared in the 1990's. However, actual centralisation was a difficult process in many countries. In this study, factors influencing the centralisation of cancer services in the Netherlands were determined. MATERIAL AND METHODS Centralisation patterns were studied for three types of cancer that are known to benefit from high surgical caseloads: oesophagus-, pancreas- and bladder cancer. The Netherlands Cancer Registry provided data on tumour and treatment characteristics from 2000-2013 for respectively 8037, 4747 and 6362 patients receiving surgery. By plotting timelines of centralisation of cancer surgery, relations with the appearance of (inter)national scientific evidence, actions of medical specialist societies, specific regulation and other important factors on the degree of centralisation were ascertained. RESULTS For oesophagus and pancreas cancer, a gradual increase in centralisation of surgery is seen from 2005 and 2006 onwards following (inter)national scientific evidence. Centralisation steps for bladder cancer surgery can be seen in 2010 and 2013 anticipating on the publication of norms by the professional society. The most influential stimulus seems to have been regulations on minimum volumes. CONCLUSION Scientific evidence on the relationship between volume and outcome lead to the start of centralisation of surgical cancer care in the Netherlands. Once a body of evidence has been established on organisational change that influences professional practice, in addition some form of regulation is needed to ensure widespread implementation.

Abstract
Objective In many countries, the evidence for volume-outcome associations in surgery has been transferred into policy. Despite the large body of research that exists on the topic, qualitative studies aimed at surgeons' views on, and experiences with, these volume-based policies are lacking. We interviewed Dutch surgeons to gain more insight into the implications of volume-outcome policies for daily clinical practice, as input for effective surgical quality improvement. Methods Semi-structured interviews were conducted with 20 purposively selected surgeons from a stratified sample for hospital type and speciality. The interviews were recorded, transcribed verbatim and underwent inductive content analysis. Results Two overarching themes were inductively derived from the data: (1) minimum volume standards and (2) implications of volume-based policies. Although surgeons acknowledged the premise 'more is better', they were critical about the validity and underlying evidence for minimum volume standards. Patients often inquire about caseload, which is met with both understanding and discomfort. Surgeons offered many examples of controversies surrounding the process of determining thresholds as well as the ways in which health insurers use volume as a purchasing criterion. Furthermore, being held accountable for caseload may trigger undesired strategic behaviour, such as unwarranted operations. Volume-based policies also have implications for the survival of low-volume providers and affect patient travel times, although the latter is not necessarily problematic in the Dutch context. Conclusions Surgeons in this study acknowledged that more volume leads to better quality. However, validity issues, undesired strategic behaviour and the ways in which minimum volume standards are established and applied have made surgeons critical of current policy practice. These findings suggest that volume remains a controversial quality measure and causes polarization that is not conducive to a collective effort for quality improvement. We recommend enforcing thresholds that are based on the best achievable level of consensus and assessing additional criteria when passing judgement on quality of care.

Abstract
Cancer cells consume a large amount of energy and maintain high levels of anabolism to promote cell proliferation via metabolic reprogramming. Nuclear factor erythroid 2-related factor 2 (Nrf2; NFE2L2) is a master transcription regulator of stress responses and promotes metabolic reprogramming to support cell proliferation in various types of cancer. As oesophageal cancer is one of the most aggressive gastrointestinal cancers, we aimed to clarify the effect of Nrf2 on metabolic reprogramming in oesophageal cancer. The relationship between Nrf2 expression and clinical outcome was evaluated using a database comprising 201 oesophageal cancers. Using in vitro assays and metabolome analysis, we examined the mechanism by which Nrf2 affects malignant phenotype. High-level immunohistochemical expression of Nrf2 was significantly associated with poor recurrence-free survival (HR = 2.67, p = 0.0004) and overall survival (HR = 2.90, p < 0.0001) in oesophageal cancer patients. In an in vitro assay with siRNA in TE-11 cells, which showed high Nrf2 expression, Nrf2 depletion significantly decreased cell growth and enhanced G1 cell cycle arrest and apoptosis. In addition, reactive oxygen species (ROS) were not removed by detoxification via the Nrf2 pathway, with concomitant induction of the p38 mitogen-activated protein kinase pathway. The metabolome analysis showed that Nrf2 strongly promoted metabolic reprogramming to glutathione metabolism, which synthesizes the essential fuels for cancer progression. Furthermore, metabolome analysis using oesophageal cancer specimens confirmed that samples displaying high Nrf2 expression promoted glutathione synthesis. Metabolic reprogramming to glutathione metabolism, and ROS detoxification by activation of Nrf2, enhanced cancer progression and led to a poor clinical outcome in oesophageal cancer patients.

Abstract
PURPOSE The purpose of this study was to investigate the relationship between the concentration of digestive system surgery and outcomes at a regional level in Japan, using time-series data. METHODS We used nationwide data from 2008 to 2013, and analyzed the ten most common surgical procedures. The unit of analysis was secondary medical areas (SMAs), which cover several municipalities and provide medical services for common diseases. The concentration of surgery in these areas was measured using the Herfindahl-Hirschman Index (HHI) and the relationship between the concentration of surgery and length of stay in hospital (LOS) was analyzed, in accordance with surgical difficulty. RESULTS There was a downward trend in both the HHI and LOS from 2008 to 2013. SMAs showing an upward trend in the HHI (increased concentration) were associated with a greater reduction in LOS than those showing a downward trend for eight surgical procedures. For three easy surgical procedures, increased concentration of surgery was significantly associated with a reduction in LOS. After adjustment for trends in the aging population and the surgical volume in 2008, an increasing concentration for three easy surgical procedures was significantly related to a reduction in the LOS. CONCLUSION Concentrating relatively easy surgical procedures at a regional level may be associated with a reduction in LOS.

Abstract
Background There is a scarcity of evidence about the role of patient choice and hospital competition policies on surgical cancer services. Previous evidence has shown that patients are prepared to bypass their nearest cancer centre to receive surgery at more distant centres that better meet their needs. In this national, population-based study we investigated the effect of patient mobility and hospital competition on service configuration and technology adoption in the National Health Service (NHS) in England, using prostate cancer surgery as a model. Methods We mapped all patients in England who underwent radical prostatectomy between Jan 1, 2010, and Dec 31, 2014, according to place of residence and treatment location. For each radical prostatectomy centre we analysed the effect of hospital competition (measured by use of a spatial competition index [SCI], with a score of 0 indicating weakest competition and 1 indicating strongest competition) and the effect of being an established robotic radical prostatectomy centre at the start of 2010 on net gains or losses of patients (difference between number of patients treated in a centre and number expected based on their residence), and the likelihood of closing their radical prostatectomy service. Findings Between Jan 1, 2010, and Dec 31, 2014, 19 256 patients underwent radical prostatectomy at an NHS provider in England. Of the 65 radical prostatectomy centres open at the start of the study period, 23 (35%) had a statistically significant net gain of patients during 2010–14. Ten (40%) of these 23 were established robotic centres. 37 (57%) of the 65 centres had a significant net loss of patients, of which two (5%) were established robotic centres and ten (27%) closed their radical prostatectomy service during the study period. Radical prostatectomy centres that closed were more likely to be located in areas with stronger competition (highest SCI quartile [0·87–0·92]; p=0·0081) than in areas with weaker competition. No robotic surgery centre closed irrespective of the size of net losses of patients. The number of centres performing robotic surgery increased from 12 (18%) of the 65 centres at the beginning of 2010 to 39 (71%) of 55 centres open at the end of 2014. Interpretation Competitive factors, in addition to policies advocating centralisation and the requirement to do minimum numbers of surgical procedures, have contributed to large-scale investment in equipment for robotic surgery without evidence of superior outcomes and contributed to the closure of cancer surgery units. If quality performance and outcome indicators are not available to guide patient choice, these policies could threaten health services' ability to deliver equitable and affordable cancer care.

Abstract
Purpose Regionalization of complex surgery to high-volume hospitals has been advocated based on cross-sectional volume-outcome studies. In April 2007, the agency overseeing cancer care in Ontario, Canada, implemented a policy to regionalize lung cancer surgery at 14 designated hospitals, enforced by economic incentives and penalties. We studied the effects of implementation of this policy. Methods Using administrative health data, we used interrupted time series models to analyze the immediate and delayed effects of implementation of the policy on the distribution of lung cancer surgery among hospitals, surgical outcomes, and health services use. Results From 2004 to 2012, 16,641 patients underwent surgery for lung cancer. The proportion of operations performed in designated hospitals increased from 71% to 89% after the policy was implemented. Although operative mortality decreased from 4.1% to 2.9% (adjusted odds ratio, 0.68; 95% CI, 0.58 to 0.81; P < .001), the reduction was due to a preexisting declining trend in mortality. In contrast, in the years after implementation of the policy, length of hospital stay decreased more than expected from the baseline trend by 7% per year (95% CI, 5% to 9%; P < .001), and the distance traveled by all patients to the hospital for surgery increased by 4% per year (95% CI, 0% to 8%; P = .03), neither of which were explained by preexisting trends. Analyses limited to patients ≥ 70 years of age demonstrated a reduction in operative mortality (odds ratio, 0.80 per year after regionalization; 95% CI, 0.67 to 0.95; P = .01). Conclusion A policy to regionalize lung cancer surgery in Ontario led to increased centralization of surgery services but was not independently associated with improvements in operative mortality. Improvements in length of stay and in operative mortality among elderly patients suggest areas where regionalization may be beneficial.
