Aim: Evidence for a positive volume–outcome relationship for rectal cancer surgery is unclear. This study aims to evaluate the volume–outcome relationship for rectal cancer surgery at hospital and surgeon level in the English National Health Service (NHS). Method: All patients undergoing a rectal cancer resection in the English NHS between 2015 and 2019 were included. Multilevel multivariable logistic regression was used to model relationships between outcomes and mean annual hospital and surgeon volumes (using a linear plus a quadratic term for volume) with adjustment for patient characteristics. Results: A total of 13 858 patients treated in 166 hospitals were included. Six hospitals (3.6%) performed fewer than 10 rectal cancer resections per year, and 381 surgeons (45.0%) performed fewer than five such resections per year. Patients treated by high‐volume surgeons had a reduced length of stay (p = 0.016). No statistically significant volume–outcome relationships were demonstrated for 90‐day mortality, 30‐day unplanned readmission, unplanned return to theatre, stoma at 18 months following anterior resection, positive circumferential resection margin and 2‐year all‐cause mortality at either hospital or surgeon level (p values > 0.05). Conclusion: Almost half of colorectal surgeons in England do not meet national guidelines for rectal cancer surgeons to perform a minimum of five major resections annually. However, our results suggest that centralizing rectal cancer surgery with the main focus of increasing operative volume may have limited impact on NHS surgical outcomes. Therefore, quality improvement initiatives should address a wider range of evidence‐based process measures, across the multidisciplinary care pathway, to enhance outcomes for patients with rectal cancer.

Aim: The aim was to compare early postoperative outcomes and 2‐year cancer‐specific mortality following colorectal cancer (CRC) resection in patients with and without inflammatory bowel disease (IBD) in England and Wales. Method: Records for patients in the National Bowel Cancer Audit who had major CRC resection between April 2014 and December 2017 were linked to routinely collected hospital level administrative datasets and chemotherapy and radiotherapy datasets. Multivariable regression models were used to compare outcomes with adjustment for patient and tumour characteristics. Results: In all, 63 365 patients were included. 1285 (2.0%) had an IBD diagnosis: 839 (65.3%) ulcerative colitis, 435 (33.9%) Crohn's disease and 11 (0.9%) were indeterminate. IBD patients were younger, had more advanced cancer staging and a higher proportion of right‐sided tumours. They also had a higher proportion of emergency resection, total/subtotal colectomy, open surgery and stoma formation at resection, with longer hospital admissions and higher rates of unplanned readmission and reoperation. Fewer rectal cancer patients with IBD received neoadjuvant radiotherapy (24.8% vs. 36.0%, P = 0.005) whilst similar proportions of Stage III colon cancer patients received adjuvant chemotherapy. Ninety‐day postoperative mortality was similar, but unadjusted 2‐year cancer‐specific mortality was significantly higher in patients with IBD (subdistribution hazard ratio 1.35, 95% CI 1.18–1.55). Risk adjustment for patient and tumour factors reduced this association (adjusted subdistribution hazard ratio 1.22, 95% CI 1.05–1.43). Conclusion: Patients with IBD and CRC are a distinct patient group who develop CRC at a younger age and undergo more radical surgery. They have worse cancer survival, with the difference in prognosis appearing after the early postoperative period. [ABSTRACT FROM AUTHOR]

Aim: The object of this work was to study how National Health Service hospitals in England and Wales aimed to maintain effective and safe colorectal cancer (CRC) services during the first peak of the COVID‐19 pandemic (April 2020). Method: A national survey was performed among all 148 hospitals providing CRC services. Information was collected about changes in referrals, diagnostic, staging and therapeutic procedures, as well as whether there was access to a 'cold site' (a hospital facility free of COVID‐19). Clinicians in each hospital were also asked to give the 'single most important lesson learned' about keeping services safe and effective. Results: Full responses were received from 123 (83%) hospitals, and information about 'cold sites' was available for 146 (99%). Eighty hospitals (54%) had access to a 'cold site' and this was increased in regions with higher COVID‐19 infection rates (p <0.001). Of the 123 responding hospitals, 105 (85%) indicated that referrals of patients with suspected CRC had dropped by at least 30%, and 69 (56%) indicated that treatment plans were altered in at least 50% of CRC patients. However, 'cold site' availability protected the capacity for diagnostic colonoscopy (p = 0.013) and CRC resection (p = 0.010). Many 'lessons learned' highlighted the importance of adequate structural service organization, often mentioning 'cold sites' and regional coordination as examples, good communication and triage of patients based on clinical urgency. Conclusion: Access to 'cold sites', as well as regional coordination, clear communication and strong leadership, were found to be pivotal in maintaining capacity for diagnosis and treatment of CRC during the COVID‐19 surge.

To date, there has been little systematic assessment of the quality of care associated with systemic anti-cancer therapy (SACT) delivery across national healthcare systems. We evaluated hospital-level toxicity rates during SACT treatment as a means of identifying variation in care quality. All colorectal cancer (CRC) patients receiving SACT within 106 English National Health Service (NHS) hospitals between 2016 and 2019 were included. Severe acute toxicity rates were derived from hospital administrative data using a validated coding framework. Variation in hospital-level toxicity rates was assessed separately in the adjuvant and metastatic settings. Toxicity rates were adjusted for age, sex, comorbidity, performance status, tumour site, and TNM staging. Eight thousand one hundred and seventy three patients received SACT in the adjuvant setting, and 7,683 patients in the metastatic setting. Adjusted severe acute toxicity rates varied between hospitals from 11% to 49% for the adjuvant cohort, and from 25% to 67% for the metastatic cohort. Compared to the national mean toxicity rate in the adjuvant cohort, six hospitals were more than two standard deviations (2SD) above, and four hospitals were more than 2SD below. In the metastatic cohort, six hospitals were more than 2SD above, and seven hospitals were more than 2SD below the national mean toxicity rate. Overall, 12 hospitals (12%) had toxicity rates more than 2SD above the national mean, and 11 (10%) had rates more than 2SD below. There is substantial variation in hospital-level severe acute toxicity rates in both the adjuvant and metastatic settings, despite risk-adjustment. Ongoing reporting of this performance indicator can be used to focus further investigation of toxicity rates and stimulate quality improvement initiatives to improve care. • Quality of SACT delivery was evaluated in adjuvant and metastatic colorectal cancer patients. • Variation in toxicity rates across 106 English NHS hospitals was used to explore this. • Adjusted toxicity rates varied from 11% to 49% (adjuvant) and from 25% to 67% (metastatic). • Twelve hospitals had toxicity rates >2SD above the national average, and 11 >2SD below. • Ongoing reporting of this performance indicator can be used for quality improvement.

Abstract Background Clinical outcomes for elderly patients undergoing liver resection for colorectal cancer (CRC) liver metastases are poorly characterised. This study aimed to investigate the impact of advancing age on the incidence of liver resection and post-operative outcomes. Methods Patients in the National Bowel Cancer Audit undergoing major CRC resection from 2010 to 2016 in England were included. Liver resection was identified from linked Hospital Episode Statistics data. A Cox-proportional hazards model was used to compare 3-year mortality. Results Of 117,005 patients, 6081 underwent liver resection. For patients <65 years there was 1 liver resection per 12 cases, 65–74, 1 per 17, and ≥75, 1 per 40. 90-day mortality after liver resection increased with advancing age (<65 0.9% (26/2829), 65–74 2.8% (57/2070), ≥75 4.0% (47/1182); P < 0.001). Age was an independent risk factor for 3-year mortality. Patients 65–74 did not have adjusted mortality higher than those <65, yet age ≥75 was associated with increased overall mortality (Hazard ratio (HR) 1.47 (95% CI 1.30–1.68)) and cancer-specific mortality (HR 1.30 (95% CI 1.13–1.49)). Conclusion Although advancing age was associated with higher rates of 90-day mortality following liver resection, 3-year mortality for patients 65–74 years was comparable to younger patients. These results will aid clinicians and patients in pre-operative decision-making. [ABSTRACT FROM AUTHOR]

Background: We used a structured approach to validate chemotherapy information derived from a national routinely collected chemotherapy dataset and from national administrative hospital data., Methods: 10,280 patients who had surgical resection with stage III colon cancer were included. First, we compared information derived from the national chemotherapy dataset (SACT) and from the administrative hospital dataset (HES) in the English NHS with respect to receipt of adjuvant chemotherapy (ACT). Second, we compared regimen and number of cycles in linked patient-level records. Third, we carried out a sensitivity analysis to establish to what extent the impact of ACT receipt differed according to data source., Results: 6,012 patients (58 %) received ACT according to either dataset. Of these patients, 3,460 (58 %) had ACT records in both datasets, 1,649 (27 %) in SACT alone, and 903 (15 %) in HES alone. Of the 3,460 patients with records in both datasets, 3,320 (96 %) had matching regimens. There was good agreement on cycle number with similar proportions of patients recorded with a single cycle (6 % in SACT vs. 7 % in HES) and slightly fewer patients recorded with more than 8 cycles in SACT (32 % in SACT vs. 35 % in HES). 3-year cancer-specific mortality was similar for patients receiving ACT, regardless of whether a patient received ACT according to SACT alone (16.6 %), according to HES alone (16.8 %), or according to either SACT or HES (17.1 %)., Conclusion: Routinely collected national chemotherapy data and administrative hospital data are highly accurate in recording regimen and number of chemotherapy cycles. However, chemotherapy information should ideally be captured from both datasets to avoid under-capture, particularly of oral chemotherapy from administrative hospital data, and to minimise bias., (Copyright © 2021 Elsevier Ltd.

Background: The existing literature does not provide a prediction model for mortality of all colorectal cancer patients using contemporary national hospital data. We developed and validated such a model to predict colorectal cancer death within 90, 180 and 365 days after diagnosis., Methods: Cohort study using linked national cancer and death records. The development population included 27,480 patients diagnosed in England in 2015. The test populations were diagnosed in England in 2016 (n = 26,411) and Wales in 2015-2016 (n = 3814). Predictors were age, gender, socioeconomic status, referral source, performance status, tumour site, TNM stage and treatment intent. Cox regression models were assessed using Brier scores, c-indices and calibration plots., Results: In the development population, 7.4, 11.7 and 17.9% of patients died from colorectal cancer within 90, 180 and 365 days after diagnosis. T4 versus T1 tumour stage had the largest adjusted association with the outcome (HR 4.67; 95% CI: 3.59-6.09). C-indices were 0.873-0.890 (England) and 0.856-0.873 (Wales) in the test populations, indicating excellent separation of predicted risks by outcome status. Models were generally well calibrated., Conclusions: The model was valid for predicting short-term colorectal cancer mortality. It can provide personalised information to support clinical practice and research.

Objective: To evaluate factors associated with the use of laparoscopic surgery and the associated postoperative outcomes for urgent or emergency resection of colorectal cancer in the English National Health Service., Summary of Background Data: Laparoscopy is increasingly used for elective colorectal cancer surgery, but uptake has been limited in the emergency setting., Methods: Patients recorded in the National Bowel Cancer Audit who underwent urgent or emergency colorectal cancer resection between April 2010 and March 2016 were included. A multivariable multilevel logistic regression model was used to estimate odds ratios (ORs) of undergoing laparoscopic resection and postoperative outcome according to approach., Results: There were 15,516 patients included. Laparoscopy use doubled from 15.1% in 2010 to 30.2% in 2016. Laparoscopy was less common in patients with poorer physical status [American Society of Anaesthesiologists (ASA) 4/5 vs 1, OR 0.29 (95% confidence interval, 95% CI 0.23-0.37), P < 0.001] and more advanced T-stage [T4 vs T0-T2, OR 0.28 (0.23-0.34), P < 0.001] and M-stage [M1 vs M0, OR 0.85 (0.75-0.96), P < 0.001]. Age, socioeconomic deprivation, nodal stage, hospital volume, and a dedicated colorectal emergency service were not associated with laparoscopy. Laparoscopic patients had a shorter length of stay [median 8 days (interquartile range (IQR) 5 to 15) vs 12 (IQR 8 to 21), adjusted mean difference -3.67 (-4.60 to 2.74), P < 0.001], and lower 90-day mortality [8.1% vs 13.0%; adjusted OR 0.78 (0.66-0.91), P = 0.004] than patients undergoing open resection. There was no significant difference in rates of readmission or reoperation by approach., Conclusion: The use of laparoscopic approach in the emergency resection of colorectal cancer is linked to a shorter length of hospital stay and reduced postoperative mortality.
