[PMID: 38707228 PMCID: PMC11066499 DOI: 10.1002/ags3.12777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 12/17/2023] [Accepted: 01/13/2024] [Indexed: 05/07/2024] Open
Abstract
Multidisciplinary management of rectal cancer has rapidly evolved over the last several years. This review describes recent data surrounding total neoadjuvant therapy, organ preservation, and management of lateral pelvic lymph nodes. It then presents our treatment algorithm for management of rectal cancer at The University of Texas MD Anderson Cancer Center in the context of this and other existing literature. As part of this discussion, the review describes how we tailor management based upon both patient and tumor-related factors in an effort to optimize patient outcomes.

Perioperative and oncological outcomes following robotic en bloc multivisceral resection for colorectal cancer. Colorectal Dis 2024; 26:949-957. [PMID: 38576073 DOI: 10.1111/codi.16964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 08/31/2023] [Accepted: 11/03/2023] [Indexed: 04/06/2024]
Abstract
AIM As multidisciplinary treatment strategies for colorectal cancer have improved, aggressive surgical resection has become commonplace. Multivisceral and extended resections offer curative-intent resection with significant survival benefit. However, limited data exist regarding the feasibility and oncological efficacy of performing extended resection via a minimally invasive approach. The aim of this study was to determine the perioperative and long-term outcomes following robotic extended resection for colorectal cancer. METHOD We describe the population of patients undergoing robotic multivisceral resection for colorectal cancer at our single institution. We evaluated perioperative details and investigated short- and long-term outcomes, using the Kaplan-Meier method to analyse overall and recurrence-free survival. RESULTS Among the 86 patients most tumours were T3 (47%) or T4 (47%) lesions in the rectum (78%). Most resections involved the anterior compartment (72%): bladder (n = 13), seminal vesicle/vas deferens (n = 27), ureter (n = 6), prostate (n = 15) and uterus/vagina/adnexa (n = 27). Three cases required conversion to open surgery; 10 patients had grade 3 complications. The median hospital stay was 4 days. Resections were R0 (>1 mm) in 78 and R1 (0 to ≤1 mm) in 8, with none being R2. The average nodal yield was 26 and 48 (55.8%) were pN0. Three-year overall survival was 88% and median progression-free survival was 19.4 months. Local recurrence was 6.1% and distant recurrence was 26.1% at 3 years. CONCLUSION Performance of multivisceral and extended resection on the robotic platform allows patients the benefit of minimally invasive surgery while achieving oncologically sound resection of colorectal cancer.

Evolving survival gains in patients with young-onset colorectal cancer and synchronous resectable liver metastases. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108057. [PMID: 38461567 DOI: 10.1016/j.ejso.2024.108057] [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: 12/26/2023] [Accepted: 02/22/2024] [Indexed: 03/12/2024]
Abstract
We aimed to evaluate the practice and the associated outcomes of surgical treatment for young-onset colorectal cancer (YOCRC) patients presenting with synchronous liver metastases. The study cohort was divided into two groups according to surgery date: 131 patients in the early era (EE, 1998-2011) and 179 in the contemporary era (CE, 2012-2020). The CE had a higher rate of node-positive primary tumors, higher carcinoembryonic antigen level, and lower rate of RAS/BRAF mutations. The CE had higher rates of reverse or combined resection, multi-drug prehepatectomy chemotherapy, and two-stage hepatectomy. The median survival was 8.4 years in the CE and 4.3 years in the EE (p = 0.011). On multivariate analysis, hepatectomy in the CE was independently associated with improved overall survival (HR 0.48, p = 0.001). With a combination of perioperative systemic therapy, careful selection of treatment approach, and coordinated resections, durable cure can be achieved in YOCRC patients.

Abstract
BACKGROUND Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored. METHOD Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition. RESULTS One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed. CONCLUSIONS EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

The effects of short-term, progressive exercise training on disease activity in smouldering multiple myeloma and monoclonal gammopathy of undetermined significance: a single-arm pilot study. BMC Cancer 2024; 24:174. [PMID: 38317104 PMCID: PMC10840198 DOI: 10.1186/s12885-024-11817-6] [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: 07/03/2023] [Accepted: 01/01/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND High levels of physical activity are associated with reduced risk of the blood cancer multiple myeloma (MM). MM is preceded by the asymptomatic stages of monoclonal gammopathy of undetermined significance (MGUS) and smouldering multiple myeloma (SMM) which are clinically managed by watchful waiting. A case study (N = 1) of a former elite athlete aged 44 years previously indicated that a multi-modal exercise programme reversed SMM disease activity. To build from this prior case study, the present pilot study firstly examined if short-term exercise training was feasible and safe for a group of MGUS and SMM patients, and secondly investigated the effects on MGUS/SMM disease activity. METHODS In this single-arm pilot study, N = 20 participants diagnosed with MGUS or SMM were allocated to receive a 16-week progressive exercise programme. Primary outcome measures were feasibility and safety. Secondary outcomes were pre- to post-exercise training changes to blood biomarkers of MGUS and SMM disease activity- monoclonal (M)-protein and free light chains (FLC)- plus cardiorespiratory and functional fitness, body composition, quality of life, blood immunophenotype, and blood biomarkers of inflammation. RESULTS Fifteen (3 MGUS and 12 SMM) participants completed the exercise programme. Adherence was 91 ± 11%. Compliance was 75 ± 25% overall, with a notable decline in compliance at intensities > 70% V̇O2PEAK. There were no serious adverse events. There were no changes to M-protein (0.0 ± 1.0 g/L, P =.903), involved FLC (+ 1.8 ± 16.8 mg/L, P =.839), or FLC difference (+ 0.2 ± 15.6 mg/L, P =.946) from pre- to post-exercise training. There were pre- to post-exercise training improvements to diastolic blood pressure (- 3 ± 5 mmHg, P =.033), sit-to-stand test performance (+ 5 ± 5 repetitions, P =.002), and energy/fatigue scores (+ 10 ± 15%, P =.026). Other secondary outcomes were unchanged. CONCLUSIONS A 16-week progressive exercise programme was feasible and safe, but did not reverse MGUS/SMM disease activity, contrasting a prior case study showing that five years of exercise training reversed SMM in a 44-year-old former athlete. Longer exercise interventions should be explored in a group of MGUS/SMM patients, with measurements of disease biomarkers, along with rates of disease progression (i.e., MGUS/SMM to MM).

Patient-Reported Sexual Function, Bladder Function and Quality of Life for Patients with Low Rectal Cancers with or without a Permanent Ostomy. Cancers (Basel) 2023; 16:153. [PMID: 38201580 PMCID: PMC10778006 DOI: 10.3390/cancers16010153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/19/2023] [Accepted: 12/20/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Despite the increasing utilization of sphincter and/or organ-preservation treatment strategies, many patients with low-lying rectal cancers require abdominoperineal resection (APR), leading to permanent ostomy. Here, we aimed to characterize overall, sexual-, and bladder-related patient-reported quality of life (QOL) for individuals with low rectal cancers. We additionally aimed to explore potential differences in patient-reported outcomes between patients with and without a permanent ostomy. METHODS We distributed a comprehensive survey consisting of various patient-reported outcome measures, including the FACT-G7 survey, ICIQ MLUTS/FLUTS, IIEF-5/FSFI, and a specific questionnaire for ostomy patients. Descriptive statistics and univariate comparisons were used to compared demographics, treatments, and QOL scores between patients with and without a permanent ostomy. RESULTS Of the 204 patients contacted, 124 (60.8%) returned completed surveys; 22 (18%) of these had a permanent ostomy at the time of survey completion. There were 25 patients with low rectal tumors (≤5 cm from the anal verge) who did not have an ostomy at the time of survey completion, of whom 13 (52%) were managed with a non-operative approach. FACTG7 scores were numerically lower (median 20.5 vs. 22, p = 0.12) for individuals with an ostomy. Sexual function measures IIEF and FSFI were also lower (worse) for individuals with ostomies, but the results were not significantly different. MLUTS and FLUTS scores were both higher in individuals with ostomies (median 11 vs. 5, p = 0.06 and median 17 vs. 5.5, p = 0.01, respectively), suggesting worse urinary function. Patient-reported ostomy-specific challenges included gastrointestinal concerns (e.g., gas, odor, diarrhea) that may affect social activities and personal relationships. CONCLUSIONS Despite a limited sample size, this study provides patient-centered, patient-derived data regarding long-term QOL in validated measures following treatment of low rectal cancers. Ostomies may have multidimensional negative impacts on QOL, and these findings warrant continued investigation in a prospective setting. These results may be used to inform shared decision making for individuals with low rectal cancers in both the settings of organ preservation and permanent ostomy.

Abstract
INTRODUCTION Patients diagnosed with coronary artery disease (CAD) are currently treated with medications and lifestyle advice to reduce the likelihood of disease progression and risk of future major adverse cardiovascular events (MACE). Where obstructive disease is diagnosed, revascularisation may be considered to treat refractory symptoms. However, many patients with coexistent cardiovascular risk factors, particularly those with metabolic syndrome (MetS), remain at heightened risk of future MACE despite current management.Cardiac rehabilitation is offered to patients post-revascularisation, however, there is no definitive evidence demonstrating its benefit in a primary prevention setting. We propose that an intensive lifestyle intervention (Super Rehab, SR) incorporating high-intensity exercise, diet and behavioural change techniques may improve symptoms, outcomes, and enable CAD regression.This study aims to examine the feasibility of delivering a multicentre randomised controlled trial (RCT) testing SR for patients with CAD, in a primary prevention setting. METHODS AND ANALYSIS This is a multicentre randomised controlled feasibility study of SR versus usual care in patients with CAD. The study aims to recruit 50 participants aged 18-75 across two centres. Feasibility will be assessed against rates of recruitment, retention and, in the intervention arm, attendance and adherence to SR. Qualitative interviews will explore trial experiences of study participants and practitioners. Variance of change in CAD across both arms of the study (assessed with serial CT coronary angiography) will inform the design and power of a future, multi-centre RCT. ETHICS AND DISSEMINATION Ethics approval was granted by South West-Frenchay Research Ethics Committee (reference: 21/SW/0153, 18 January 2022). Study findings will be disseminated via presentations to relevant stakeholders, national and international conferences and open-access peer-reviewed research publications.

Rectal Adenocarcinoma Presenting as a Cervical Mass: A Case Report. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e941884.

Abstract
BACKGROUND Invasive cervical tumors are often seen in clinical practice. However, there are multiple structures within the pelvis, and invasion of the cervix from another site must be included in the differential diagnosis. In such cases, a multidisciplinary approach is needed to define the organ of tumor origin. Ensuring proper staging and histologic analysis are critical for optimal management. CASE REPORT We present a case of a 68-year-old woman who presented to her gynecologist with painless post-menopausal vaginal bleeding. She was diagnosed with a locally aggressive cervical adenocarcinoma, which was histologically confirmed by an in-office biopsy. She was referred to the gynecologic oncology service at a tertiary care hospital for definitive management, where a thorough clinical workup was performed. Physical exam revealed that the mass had invaded the anterior rectal wall. Through a multidisciplinary approach and a repeat biopsy, she was correctly diagnosed with an invasive rectal adenocarcinoma. She was treated with neoadjuvant chemoradiotherapy and underwent curative surgery. Had she been incorrectly treated as having a primary cervical adenocarcinoma, there would have been no role for surgery. The change in the organ of primary drastically altered the patient's management and outcome. She is currently undergoing surveillance with cross-sectional imaging. CONCLUSIONS Cervical masses originating from non-gynecologic organs can be difficult to differentiate on physical exam and histologic analysis. When a mass involves the rectum, an invasive primary rectal adenocarcinoma must be included in the differential. This will have a significant impact on patient management and ultimately on patient survival.

Abstract
Importance Circumferential resection margin (CRM) in rectal cancer surgery is a major prognostic indicator associated with local recurrence and overall survival. Facility rates of CRM positivity have recently been established as a new quality measure by the Commission on Cancer (CoC); however, the completeness of CRM status reporting is not well characterized. Objective To describe the changes in CRM reporting and factors associated with low rates of reporting. Design, Setting, and Participants A retrospective cohort study was conducted using data from the National Cancer Database between January 2010 and December 2019. Data were analyzed between October 1, 2021, and February 1, 2022. Data from the National Cancer Database included patients diagnosed with nonmetastatic rectal adenocarcinoma receiving surgical treatment at CoC-accredited facilities throughout the US. Exposures Patient, tumor, and facility-level factors. Facilities were divided by surgical volume, safety-net status, and CoC facility type. Main Outcomes and Measures Circumferential resection margin missingness rates. Results A total of 110 571 patients (59.3% men) with rectal adenocarcinoma who underwent curative-intent surgery at 1307 CoC-accredited hospitals were included for analysis. Reporting of CRM improved over the study period, with a mean (SE) missing 12.0% (0.32%) decreased from 16.3% (0.36%). Academic facilities had a higher missingness than other facility types (14.3% vs 10.5%-12.7%; P < .001). Mean (SE) rates of missingness were similar between hospitals of varying volume (lowest quartile: 12.2% [0.93%] vs highest quartile: 12.4% [0.53%]; P = .96). Cases in which fewer than 12 lymph nodes were removed had higher rates of missingness (18.1% vs 11.4%; P < .001). Increased odds of CRM missingness were noted with T category (odds ratio [OR], 1.50; 95% CI, 1.35-1.65) and N category (OR, 2.00; 95% CI, 1.82-2.20). Black race was associated with missingness (OR, 1.13; 95% CI, 1.06-1.14). Conclusion and Relevance Although CRM positivity reporting has improved over the last decade, the findings of this study suggest there is substantial room for improvement as it becomes a quality standard. Missingness appears to be associated with poor performance on other quality metrics and facility type. This measure appears to be ideal for targeted institution-level feedback to improve quality of care nationally.

Abstract
OBJECTIVE External exposures, the host, and the microbiome interact in oncology. We aimed to investigate tumoral microbiomes in young-onset rectal cancers (YORCs) for profiles potentially correlative with disease etiology and biology. BACKGROUND YORC is rapidly increasing, with 1 in 4 new rectal cancer cases occurring under the age of 50 years. Its etiology is unknown. METHODS YORC (<50 y old) or later-onset rectal cancer (LORC, ≥50 y old) patients underwent pretreatment biopsied of tumor and tumor-adjacent normal (TAN) tissue. After whole genome sequencing, metagenomic analysis quantified microbial communities comparing tumors versus TANs and YORCs versus LORCs, controlling for multiple testing. Response to neoadjuvant therapy (NT) was categorized as major pathological response (MPR, ≤10% residual viable tumor) versus non-MPR. RESULTS Our 107 tumors, 75 TANs from 37 (35%) YORCs, and 70 (65%) LORCs recapitulated bacterial species were previously associated with colorectal cancers (all P <0.0001). YORC and LORC tumoral microbiome signatures were distinct. After NT, 13 patients (12.4%) achieved complete pathologic response, whereas MPR occurred in 47 patients (44%). Among YORCs, MPR was associated with Fusobacterium nucleaum , Bacteroides dorei, and Ruminococcus bromii (all P <0.001), but MPR in LORC was associated with R. bromii ( P <0.001). Network analysis of non-MPR tumors demonstrated a preponderance of oral bacteria not observed in MPR tumors. CONCLUSIONS Microbial signatures were distinct between YORC and LORC. Failure to achieve an MPR was associated with oral bacteria in tumors. These findings urge further studies to decipher correlative versus mechanistic associations but suggest a potential for microbial modulation to augment current treatments.

Abstract
PURPOSE/OBJECTIVE(S) Low anterior resection syndrome (LARS) describes disordered bowel function including tenesmus, frequent, clustered, incomplete, urgent or incontinent bowel movements. The impact of clinical and radiation dosimetric factors on LARS score is unknown. We aimed to evaluate the radiation plans for patients who received long course chemoradiation (LC-CRT) to identify potential dosimetric predictors of LARS. MATERIALS/METHODS We identified patients with rectal cancer treated with LC-CRT (50.4Gy in 28 fractions) at our institution from 2016-2020 who were alive and without disease. As a part of a larger patient-reported outcome survey, we obtained the Low Anterior Resection Syndrome Score (LARS) for patients without an ostomy at the time of the survey. We utilized clinical and dosimetric variables in a multivariate analysis including age at LC-CRT, body mass index, sex, distance of the tumor from the anal verge (AV), threatened mesorectal fascia (MRF) on staging imaging, T-stage, N-stage, receipt of surgery (vs non-operative management (NOM), radiation technique (3DCRT vs VMAT), mean dose and D0.03ccs for the anal canal (defined as 4cm from the anal verge) and D0.03cc, V30Gy and V45Gy for the small bowel loops. We then created a multiple linear regression model to predict LARS using P>.20 on univariate testing. RESULTS Of 110 patients treated with preoperative LC-CRT and who did not have an ostomy, 57 responded (51.8%). The median [interquartile range (IQR)] interval from completion of LC-CRT to survey completion was 38.4 months [26.3-48.9]. Thirty-four patients (60%) were men, the median [IQR] BMI was 28 [24-31.9], the median [IQR] distance of the tumor to the anal verge was 7cm [5-10], 40 (70%) had T3 tumors, 7 (12%) had T4 tumors, 45 (79%) were N+. Forty-one patients (72%) had surgery following LC-CRT, and 16 (28%) had non-operative management. 3D conformal technique was used for 47 (82%) and VMAT used for 10 patients (18%). The median [IQR] LARS score was 32 [24-38] with 35 patients (61%) classified as Major LARS (LARS score = 30-42). On multiple linear regression modeling (Table), only receipt of surgery significantly predicted for higher (worse) LARS score. CONCLUSION In our cohort, patients who received surgery after LC-CRT had a significantly higher LARS score. Of the dosimetric parameters tested, D0.03ccs was the best predictor and could potentially be significant with a larger number of patients. Further work is needed to improve bowel function and quality of life for patients treated with LC-CRT for rectal adenocarcinoma.

Abstract
OBJECTIVE Explore the experiences of patients and clinicians in rheumatology and cardiology outpatient clinics during the first year of the COVID-19 pandemic, focusing on the impact of remote consultations on interpersonal dynamics. DESIGN Qualitative study using semistructured interviews, conducted between February and June 2021. SETTING The rheumatology and cardiology departments of a general hospital in England, UK. PARTICIPANTS All clinicians and a convenience sample of 100 patients in each department who had taken part in a remote consultation in the past month were invited to take part. Twenty-five interviews were conducted (13 with patients, 12 with clinicians). RESULTS Three themes were developed through the analysis: adapting to the dynamics of remote consultations, impact on the patient's experience and impact on the clinician's experience. The majority of remote consultations experienced by both patients and clinicians had been via telephone. Both clinicians and patients found remote consultations to be more business-like and focused, with the absence of pauses restricting time for reflection. For patients with stable, well-managed conditions, remote consultations were felt to be appropriate and could be more convenient than in-person consultations. However, the loss of visual cues meant some patients felt they could not give a holistic view of their condition and limited clinicians' ability to gather and convey information. Clinicians adjusted their approach by asking more questions, checking understanding more frequently and expressing empathy verbally, but felt patients still shared fewer concerns remotely than in person; a perception with which patients concurred. CONCLUSIONS These findings highlight the importance of ensuring, for each patient, that remote care is appropriate. Future research should focus on developing ways to support both clinicians and patients to gather and provide all information necessary during remote consultations, to enhance communication and trust.

[PMID: 36878805 DOI: 10.1016/j.clcc.2023.02.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 02/10/2023] [Indexed: 02/17/2023]
Abstract
INTRODUCTION Multimodality treatment for locally advanced rectal cancer (LARC) can include long-course radiotherapy (LCRT) or short course radiotherapy (SCRT). Nonoperative management is increasingly pursued for those achieving a complete clinical response. Data regarding long-term function and quality-of-life (QOL) are limited. METHODS Patients with LARC treated with radiotherapy from 2016 to 2020 completed the Functional Assessment of Cancer Therapy- General (FACT-G7), the Low Anterior Resection Syndrome Score (LARS) and the Fecal Incontinence QOL Scale (FIQOL). Univariate and multivariable linear regression analyses identified associations between clinical variables including radiation fractionation and the use of surgery versus non-operative management. RESULTS Of 204 patients surveyed, 124 (60.8%) responded. Median (interquartile range) time from radiation to survey completion was 30.1 (18.3-43) months. Seventy-nine (63.7%) respondents received LCRT, and 45 (36.3%) received SCRT; 101 (81.5%) respondents underwent surgery, and 23 (18.5%) pursued nonoperative management. There were no differences in LARS, FIQoL or FACT-G7 between patients receiving LCRT versus SCRT. On multivariable analysis, only nonoperative management was associated with lower LARS score signifying less bowel dysfunction. Nonoperative management and female sex were associated with a higher FIQoL score signifying less disruption and distress from fecal incontinence issues. Finally, lower BMI at the time of radiation, female sex, and higher FIQoL score were associated with higher FACT-G7 scores signifying better overall QOL. CONCLUSIONS These results suggest long-term patient-reported bowel function and QOL may be similar for individuals receiving SCRT and LCRT for the treatment of LARC, but nonoperative management may lead to improved bowel function and QOL.

Internet-based assessment tools for predicting colorectal cancer risk: How do they communicate individualized risk to the young adult? J Clin Oncol 2023.

Abstract
72 Background: Online prediction tools for cancer risk can inform individuals about their risk and potentially encourage adoption of risk-modifying health behavior. The Colorectal Cancer Risk Assessment Tool (CCRAT) is an interactive tool developed by the National Cancer Institute for estimating colorectal cancer (CRC) risk for individuals between the ages of 45 and 85 without high risk predisposing conditions. Given the rising incidence of CRC among young adults under age 50, we aimed to investigate the performance of CCRAT in estimating their CRC risk. Methods: An institutional protocol prospectively enrolled 563 patients newly diagnosed with non-hereditary CRC and administered a health behavior questionnaire at baseline. Self-reported demographics, diet and physical activity, medication use, and family history were extracted and entered into the CCRAT ( https://ccrisktool.cancer.gov/calculator.html ) to calculate their predicted 5-year and lifetime CRC risks. Health behaviors and the predicted CRC risks in reference to the population average were compared among three groups: youngest- (aged 18-44, N = 276, 49%), young- (aged 45-50, N = 178, 32%), and older-onset (aged > 50, N = 109; 19%). Results: The patient groups did not significantly differ in gender or in family history of CRC, but the youngest group had significantly more non-White patients (27, 22, vs. 19%; p = 0.008) and distal tumors (80, 76 and 65%; p = 0.05). The youngest and young groups had a higher prevalence of morbid obesity (18 and 15% vs. 12%; p = 0.002) and active smokers (6 and 8% vs. 3%; p = 0.005). There were no significant differences in vegetable intake, moderate exercise, NSAID use, or female hormone use. The 5-year CRC risk was correctly predicted as “higher than average population” for a significantly smaller proportion of the youngest (42%) and young (45%) patients, when compared to their older counterpart (71%; p < 0.001). Similarly, the tool communicated “higher than average” lifetime risk for CRC in only 56 and 60% of the youngest and young patients, but 72% of the older ones (p = 0.021). Conclusions: The existing risk prediction tool inadequately communicated CRC risk for adults younger than 50 years of age. Risk factors underlying young-onset CRC likely differ from and extend beyond those as currently assessed. New tools capturing age-specific risk factors are needed to accurately communicate individualized risk and potentially motivate risk-modifying lifestyles.

Time trends in the incidence rates of venous thromboembolism following colorectal resection by indication and operative technique. Colorectal Dis 2022; 24:1405-1415. [PMID: 35733416 PMCID: PMC9796069 DOI: 10.1111/codi.16233] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 05/30/2022] [Accepted: 06/14/2022] [Indexed: 12/30/2022]
Abstract
AIM It is important for patient safety to assess if international changes in perioperative care, such as the focus on venous thromboembolism (VTE) prevention and minimally invasive surgery, have reduced the high post colectomy VTE risks previously reported. This study assesses the impact of changes in perioperative care on VTE risk following colorectal resection. METHOD This was a population-based cohort study of colectomy patients in England between 2000 and 2019 using a national database of linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care data. Within 30 days following colectomy, absolute VTE rates per 1000 person-years and adjusted incidence rate ratios (aIRRs) using Poisson regression for the per year change in VTE risk were calculated. RESULTS Of 183 791 patients, 1337 (0.73%) developed 30-day postoperative VTE. Overall, VTE rates reduced over the 20-year study period following elective (relative risk reduction 31.25%, 95% CI 5.69%-49.88%) but not emergency surgery. Similarly, yearly changes in VTE risk reduced following minimally invasive resections (elective benign, aIRR 0.93, 95% CI 0.90-0.97; elective malignant, aIRR 0.94, 95% CI 0.91-0.98; and emergency benign, aIRR 0.96, 95% CI 0.92-1.00) but not following open resections. There was a per year VTE risk increase following open emergency malignant resections (aIRR 1.02, 95% CI 1.00-1.04). CONCLUSION Yearly VTE risks reduced following minimally invasive surgeries in the elective setting yet in contrast were static following open elective colectomies, and following emergency malignant resections increased by almost 2% per year. To reduce VTE risk, further efforts are required to implement advances in surgical care for those having emergency and/or open surgery.

Abstract
OBJECTIVE Lateral pelvic lymph node (LPLN) metastases are an important cause of preventable local failure in rectal cancer. The aim of this study was to evaluate clinical and oncological outcomes following magnetic resonance imaging (MRI)-directed surgical selection for lateral pelvic lymph node dissection (LPLND) after total neoadjuvant therapy (TNT). METHODS A retrospective consecutive cohort analysis was performed of rectal cancer patients with enlarged LPLN on pretreatment MRI. Patients were categorized as LPLND or non-LPLND. The main outcomes were lateral local recurrence rate, perioperative and oncological outcomes and factors associated with decision making for LPLND. RESULTS A total of 158 patients with enlarged pretreatment LPLN and treated with TNT were identified. Median follow-up was 20 months (interquartile range 10-32). After multidisciplinary review, 88 patients (56.0%) underwent LPLND. Mean age was 53 (SD±12) years, and 54 (34.2%) were female. Total operative time (509 vs 429 minutes; P =0.003) was greater in the LPLND group, but median blood loss ( P =0.70) or rates of major morbidity (19.3% vs 17.0%) did not differ. LPLNs were pathologically positive in 34.1%. The 3-year lateral local recurrence rates (3.4% vs 4.6%; P =0.85) did not differ between groups. Patients with LPLNs demonstrating pretreatment heterogeneity and irregular margin (odds ratio, 3.82; 95% confidence interval: 1.65-8.82) or with short-axis ≥5 mm post-TNT (odds ratio 2.69; 95% confidence interval: 1.19-6.08) were more likely to undergo LPLND. CONCLUSIONS For rectal cancer patients with evidence of LPLN metastasis, the appropriate selection of patients for LPLND can be facilitated by a multidisciplinary MRI-directed approach with no significant difference in perioperative or oncologic outcomes.

Abstract
OBJECTIVE To assess the impact of current guidelines by reporting weekly postoperative postdischarge venous thromboembolism (VTE) rates. SUMMARY BACKGROUND DATA Disparity exists between the postoperative thromboprophylaxis duration colectomy patients receive based on surgical indication, where malignant resections routinely receive 28 days extended thromboprophylaxis into the postdischarge period and benign resections do not. METHODS English national cohort study of colectomy patients between 2010 and 2019 using linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care data. Stratified by admission type and surgical indication, absolute incidence rates (IRs) per 1000 person-years and adjusted incidence rate ratios (aIRRs) for postdischarge VTE were calculated for the first 4 weeks following resection and postdischarge VTE IRs for each postoperative week to 12 weeks postoperative. RESULTS Of 104,744 patients, 663 (0.63%) developed postdischarge VTE within 12 weeks after colectomy. Postdischarge VTE IRs per 1000 person-years for the first 4 weeks postoperative were low following elective resections [benign: 20.66, 95% confidence interval (CI): 13.73-31.08; malignant: 28.95, 95% CI: 23.09-36.31] and higher following emergency resections (benign: 47.31, 95% CI: 34.43-65.02; malignant: 107.18, 95% CI: 78.62-146.12). Compared with elective malignant resections, there was no difference in postdischarge VTE risk within 4 weeks following elective benign colectomy (aIRR=0.92, 95% CI: 0.56-1.50). However, postdischarge VTE risks within 4 weeks following emergency resections were significantly greater for benign (aIRR=1.89, 95% CI: 1.22-2.94) and malignant (aIRR=3.13, 95% CI: 2.06-4.76) indications compared with elective malignant colectomy. CONCLUSIONS Postdischarge VTE risk within 4 weeks of colectomy is ∼2-fold greater following emergency benign compared with elective malignant resections, suggesting emergency benign colectomy patients may benefit from extended VTE prophylaxis.

Developing non-exercise activity thermogenesis (NEAT) through building design. FACILITIES 2022. [DOI: 10.1108/f-01-2022-0002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
Purpose
Physical inactivity has a considerable negative impact on health. Physical activity has reduced partly due to workplace and lifestyle changes, causing people to spend more time in buildings and increasing sedentary behaviour. The purpose of this paper is to address a largely untapped opportunity for designers and managers to improve building users’ health by designing buildings that raise users’ Non-Exercise Activity Thermogenesis (NEAT) levels. In this research a conceptual model was developed to assess buildings’ performance in providing NEAT-promoting opportunities through building design features and management, in relation to building users’ propensity for NEAT behaviours.
Design/methodology/approach
The conceptual model was developed by a multi-disciplinary team of researchers and data to populate the model was obtained through a survey of 75 buildings in Jakarta (Indonesia).
Findings
The presented proof-of-concept shows that the model’s “meso-scale” approach to study physical activity and building design can lead to potential improvements of NEAT levels and physical activity in buildings.
Originality/value
The review of precedent models shows that this subject has been researched at micro-scale (i.e. detailed monitoring of individuals’ movement) and macro-scale (i.e. epidemiological studies of populations’ health). The presented model is original, as it explores a “meso-scale”(i.e. building scale) that is unique.

Abstract
Background Despite reforming health policies to create more enabling environments, insufficient physical activity in Sri Lanka remains a major public health issue. Socio-culture specific determinants underlying the physical activity of adults living in such environments need to be identified. The aim of this study was to explore the barriers and facilitators for physical activity, as perceived by adult urban dwellers in activity-friendly environments in Colombo District, Sri Lanka. Methods A qualitative study using in-depth interviews was conducted among adults aged 20–60 years living in an urban area which has been recently re-designed for recreational and rejuvenating purposes in Sri Lanka. Recruitment targeted varying socio-economic status and risk of non-communicable diseases; and was continued until the data saturation point was reached. Interviews were conducted in homes, primary healthcare units and fitness centres, and were transcribed verbatim and analysed using framework analysis. Results A total of 31 eligible and consenting adults were interviewed. Of the reported barriers to physical activity, lack of time was very common. Other frequently reported barriers included unpleasant experiences following exercise and misconceptions about exercise, whereas physical environmental factors, weather and road safety were reported less frequently. All participants reported at least one facilitator for engaging in exercise. Expectations of preventing diseases, improving health, physical fitness, psycho-social wellbeing, optimising body functions and increasing lifespan were frequently cited as reasons to be active, while social factors such as positive attitudes of family members and the influence of peers were found to be motivating. Conclusions The study showed that while participants valued the health benefits of physical activity and refurbished activity-friendly urban environments, these were not sufficient to support them to overcome key perceived barriers to being physically active.

Abstract
Total neoadjuvant therapy (TNT) for rectal cancer is the preoperative delivery of radiation or chemoradiotherapy as well as systemic chemotherapy for the purpose of improving treatment completion rates and decreasing toxicity, maximizing the primary tumor response, and improving survival for patients with rectal cancer. This review summarizes the data surrounding TNT, including several recent randomized controlled trials. Moreover, it reviews the literature regarding high-quality surgery and the role of radiation and chemotherapy in the treatment of rectal cancer in the modern era. Finally, it presents an evidence-based protocol for the selective use of TNT in the treatment of patients with rectal cancer.

Abstract
Background: Many children are not engaging in sufficient physical activity and there are substantial between-children physical activity inequalities. In addition to their primary role as educators, teachers are often regarded as being well-placed to make vital contributions to inclusive visions of physical activity promotion. With the dramatic increase in popularity of wearable technologies for physical activity promotion in recent years, there is a need to better understand teachers' perspectives about using such devices, and the data they produce, to support physical activity promotion in schools. Method: Semi-structured interviews were conducted with 26 UK-based primary school teachers, exploring their responses to children's physical activity data and their views about using wearable technologies during the school day. Interview discussions were facilitated by an elicitation technique whereby participants were presented with graphs illustrating children's in-school physical activity obtained from secondary wearable technology data. Interview transcripts were thematically analyzed. Results: Most teachers spoke positively about the use of wearable technologies specifically designed for school use, highlighting potential benefits and considerations. Many teachers were able to understand and critically interpret data showing unequal physical activity patterns both within-and between-schools. Being presented with the data prompted teachers to provide explanations about observable patterns, emotional reactions-particularly about inequalities-and express motivations to change the current situations in schools. Conclusion: These findings suggest that primary school teachers in the UK are open to integrating wearable technology for measuring children's physical activity into their practices and can interpret the data produced by such devices. Visual representations of physical activity elicited strong responses and thus could be used when working with teachers as an effective trigger to inform school practices and policies seeking to address in-school physical inactivity and inequalities.

Abstract
BACKGROUND Although currently limited, the requirement for colorectal trainees to attain skills in robotic surgery is likely to increase due to further utilization of robotic platforms globally. The aim of the study is to describe the training programme utilized and assess outcomes of fellowship training in robotic colorectal surgery. METHODS A structured robotic training programme was generated across a tertiary hospital setting. Review of four prospectively maintained fellow operative logbooks was performed to assess caseload and skill acquisition. Operative and patient-related outcomes were compared with consultant trainer performed cases. Data were analysed using R with a P < 0.05 considered significant. RESULTS The structured robotic training scheme is a two-tiered system over a 12-month period. The trainer-directed pathway comprised of a robotic console safety course followed by cart-side assisting, a wet lab animal course, dual-console accreditation training course and onsite proctoring, prior to becoming an independent console surgeon. Over 2 years, 265 robotic (n = 143 primary/component surgeon) cases were undertaken with fellows A, B, C and D involved in 63, 77, 75 and 50 robotic colorectal cases, respectively. Individual learning curves revealed independent procedure competency at cases 11, 14, 15 and 12, respectively, for robotic anterior resection. There was no significant difference observed in operative time (P = 0.39), blood loss (P = 0.41), lymph node harvest (P = 0.35), conversion rates (2% versus 4%), anastomotic leaks (1% versus 3%) and R0 resection rates (100% versus 98% colonic, 96% versus 96% rectal, P = 0.48) between surgical fellows and consultant trainers. Clavien-Dindo(III-IV) complications were similar (10% versus 6%,P = 0.25) with no mortalities encountered. CONCLUSION It is feasible and safe to train fellows in robotic colorectal surgery without compromise of operative- and patient-related outcomes.

Abstract
Background Past studies have highlighted variation in in-hospital mortality rates among hospitals performing emergency laparotomy for large bowel perforation. The aim of this study was to investigate whether failure to rescue (FTR) contributes to this variability. Methods Patients aged 18 years or over requiring surgery for large bowel perforation between 2013 and 2016 were extracted from the National Emergency Laparotomy Audit (NELA) database. Information on complications were identified using linked Hospital Episode Statistics data and in-hospital deaths from the Office for National Statistics. The FTR rate was defined as the proportion of patients dying in hospital with a recorded complication, and was examined in hospitals grouped as having low, medium or high overall postoperative mortality. Results Overall, 6413 patients were included with 1029 (16.0 per cent) in-hospital deaths. Some 3533 patients (55.1 per cent) had at least one complication: 1023 surgical (16.0 per cent) and 3332 medical (52.0 per cent) complications. There were 22 in-hospital deaths following a surgical complication alone, 685 deaths following a medical complication alone, 150 deaths following both a surgical and medical complication, and 172 deaths with no recorded complication. The risk of in-hospital death was high among patients who suffered either type of complication (857 deaths in 3533 patients; FTR rate 24.3 per cent): 172 deaths followed a surgical complication (FTR-surgical rate 16.8 per cent) and 835 deaths followed a medical complication (FTR-medical rate of 25.1 per cent). After adjustment for patient characteristics and hospital factors, hospitals grouped as having low, medium or high overall postoperative mortality did not have different FTR rates (P = 0.770). Conclusion Among patients having emergency laparotomy for large bowel perforation, efforts to reduce the risk of in-hospital death should focus on reducing avoidable complications. There was no evidence of variation in FTR rates across National Health Service hospitals in England.

Abstract
AIM There are limited outcome data for lateral pelvic lymph node dissection (LPLND) following neoadjuvant chemoradiotherapy (nCRT), particularly in the West. Our aim was to evaluate the short-term perioperative and oncological outcomes of robotic LPLND at a single cancer centre. METHOD A retrospective analysis of a prospective database of consecutive patients undergoing robotic LPLND for rectal cancer between November 2012 and February 2020 was performed. The main outcomes were short-term perioperative and oncological outcomes. Major morbidity was defined as Clavien-Dindo grade 3 or above. RESULTS Forty patients underwent robotic LPLND during the study period. The mean age was 54 years (SD ± 15 years) and 13 (31.0%) were female. The median body mass index was 28.6 kg/m2 (IQR 25.5-32.6 kg/m2 ). Neoadjuvant CRT was performed in all patients. Resection of the primary rectal cancer and concurrent LPLND occurred in 36 (90.0%) patients, whilst the remaining 4 (10.0%) patients had subsequent LPLND after prior rectal resection. The median operating time was 420 min (IQR 313-540 min), estimated blood loss was 150 ml (IQR 55-200 ml) and length of hospital stay was 4 days (IQR 3-6 days). The major morbidity rate was 10.0% (n = 4). The median lymph node harvest from the LPLND was 6 (IQR 3-9) and 13 (32.5%) patients had one or more positive LPLNs. The median follow-up was 16 months (IQR 5-33 months), with 1 (2.5%) local central recurrence and 7 (17.5%) patients developing distant disease, resulting in 3 (7.5%) deaths. CONCLUSION Robotic LPLND for rectal cancer can be performed in Western patients to completely resect extra-mesorectal LPLNs and is associated with acceptable perioperative morbidity.

Abdominoperineal excision in Australasia: clinical outcomes, predictive factors and recent trends of nonrestorative rectal cancer surgery. Colorectal Dis 2020; 22:1614-1625. [PMID: 32663900 DOI: 10.1111/codi.15263] [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: 12/06/2019] [Accepted: 05/20/2020] [Indexed: 12/13/2022]
Abstract
AIM The decision to perform an abdominoperineal excision (APR) rather than restorative bowel resection relies on a number of clinical factors. There remains great variability in APR rates internationally. The aim of this study was to demonstrate trends of APR surgery in low rectal cancer (< 6 cm from the anal verge) in Australasia and identify predictors of nonrestoration. METHOD This study reviewed a prospectively maintained colorectal registry - the Binational Colorectal Cancer Audit (BCCA) - from general/colorectal surgical units across Australia and New Zealand. Data were analysed to determine factors predictive of nonrestorative resection. Patients were analysed based on the presence (control) or absence (comparison) of a primary anastomosis. RESULTS Of 3628 patients with rectal cancer, 2096 were diagnosed with low rectal cancer between 2007 and 2017. The incidence of APR remained constant over the study period, with 58% of all resections of low rectal cancer being APR. The majority of resections were performed by consultants in urban hospitals (86% vs 14%). Tumours ≤ 3 cm from the anal verge, T4, M1 disease and neoadjuvant therapy were the greatest predictors of APR (P < 0.001). A significantly increased rate of restorative surgery was observed in public hospital settings (59% vs 41%, P < 0.05). The rate of positive circumferential resection margin (CRM) was 7.95%, with significantly increased rates in patients undergoing APR (12.2% vs 6.2%, P < 0.001). CRM positivity was increased in open approaches, T4, N2 and M1 staged disease and in an emergency/urgent setting (P < 0.001 and P < 0.045, respectively). Significantly increased wound and pulmonary complications were observed in the APR cohort (P < 0.01). CONCLUSION The rates of APR in Australia and New Zealand remain high but are comparable to international figures, with one-third of rectal cancers being treated by APR. The main determinants of APR are tumour height, T stage and neoadjuvant therapy requirement. CRM positivity was higher in APR patients.

Abstract
AIM Robotic transanal minimally invasive surgery (R-TAMIS) is gaining traction around the globe as an alternative to laparoscopic conventional TAMIS for local excision of benign and early malignant rectal lesions. The aim was to analyse patient and oncological outcomes of R-TAMIS for consecutive cases in a single centre. METHODS A prospective analysis of consecutive R-TAMIS procedures over a 12-month period was performed. Data were collated from hospital databases and theatre registers. RESULTS Eleven patients (six men, five women), mean age 69.81 years (51-92 years), underwent R-TAMIS over 12 months utilizing a da Vinci Xi platform. The mean lesion size was 36 mm (20-60 mm) with a mean distance from the anal verge of 7.5 cm (3-14 cm). Five lesions were posterior in anatomical location, four anterior, one right lateral and one left lateral. All procedures were performed in the lithotomy position using a GelPOINT Path Platform. Mean operative time was 64 min (40-100 min). Complete resection was achieved in 10/11 patients with two patients being upgraded to a diagnosis of adenocarcinoma. Nine patients were diagnosed with dysplastic lesions. Four patients had a false positive diagnosis of an invasive tumour on MRI. Six patients required suturing for full-thickness resections. One patient had a postoperative bleed requiring repeat endoscopy and clipping. One patient (full-thickness resection of T3 tumour) proceeded to a formal resection without difficulty with no residual disease (T0N0, 0/22). One patient with a fully resected T2 tumour is undergoing a surveillance protocol. The mean length of stay was 1 day with two patients having a length of stay of 2 days and one patient of 4 days. CONCLUSION R-TAMIS could potentially represent a safe novel approach for local resection of rectal lesions.

Abstract
BACKGROUND The management of patients presenting with malignant small bowel obstruction is a challenging paradigm. The aim of this systematic review was to examine different management strategies in these complex patients. The primary outcomes evaluated were the type of intervention, 30-day morbidity and mortality and overall survival rates. METHODS A systematic literature review of EMBase, Medline, PubMed and the Cochrane Library was performed using Preferred Reporting Items for Systematic reviews and Meta-Analyses for studies reporting on conservative and operative management of malignant small bowel obstruction. RESULTS Fifteen studies (n = 882 patients) reporting on outcomes for malignant small bowel obstruction were analysed. Outcomes measured were primarily survival and relief of obstructive symptoms. The median age ranged from 52 to 66 years. The most common cause of malignant small bowel obstruction was gynaecological in nature (56%), followed by colorectal (19%). Four hundred and eighty-six patients underwent primary surgical management and the remaining 396 patients were assigned to non-surgical intervention. Median overall survival in the operative studies ranged from 2.5 to 7.4 months compared with 0.9 to 1.9 months (P < 0.05). The 30-day mortality ranged from 13% to 28% in those who underwent surgical interventions versus 2% to 61% in the non-surgical group (P = 0.09). No significant difference in median survival in gastrointestinal (GI) and gynaecological malignancies was observed (4.3 versus 5.0 months, P = 0.12). Morbidity ranged from 21% to 85% in the surgical group and 12% to 29% in the percutaneous groups (P < 0.05). CONCLUSION Surgical intervention in malignant small bowel obstruction is associated with significant morbidity, although it may improve survival in selected patients with gynaecological and colorectal malignancy. It is imperative that realistic goals and expectations are discussed with patients preoperatively.

Abstract
AIM Currently, there is no clear consensus on the role of extended pelvic resections for locally advanced or recurrent disease involving major vascular structures. The aims of this study were to report the outcomes of consecutive patients undergoing extended resections for pelvic malignancy involving the aortoiliac axis. METHODS Prospective data were collected on patients having extended radical resections for locally advanced or recurrent pelvic malignancies, with aortoiliac axis involvement, requiring en bloc vascular resection and reconstruction, at a single institution between 2014 and 2018. RESULTS Eleven patients were included (median age 60 years; range 31-69 years; seven women). The majority required resection of both arterial and venous systems (n = 8), and the technique for vascular reconstruction was either interposition grafts or femoral-femoral crossover grafts. The median operative time was 510 min (range 330-960 min). Clear resection margins (R0) were achieved in nine patients. The median length of stay was 25 days (range 7-83 days). Seven patients did not suffer an early complication. There was one serious complication (Clavien-Dindo ≥ 3), an arterial graft occlusion secondary to thrombus in the immediate postoperative period, requiring a return to theatre and thrombectomy. The median length of follow-up in this study was 22 months (range 4-58 months). CONCLUSION This series demonstrates that en bloc major vascular resection and reconstruction can be performed safely and can achieve clear resection margins in selected patients with locally advanced or recurrent pelvic malignancy at specialist surgery centres.

Abstract
There has historically been a significant divide in the approach to the management of lateral pelvic lymph nodes in patients with rectal cancer. These differing paradigms have developed based upon competing priorities. In the West, the circumferential resection margin has been the main focus because it is a strong predictor of local recurrence, distal recurrence, and survival. This approach was supplemented by radiation and chemotherapy to treat the lateral pelvic lymph nodes and micrometastatic disease. In the East, lateral pelvic lymph nodes are considered to be locoregional; thus, surgical treatment has traditionally included routine dissection of this compartment for low rectal cancers without the use of neoadjuvant chemoradiotherapy. However, neither approach has adequately addressed the important issue of lateral compartment recurrence in patients with clinically evident lateral pelvic lymph node metastasis. The aims of the review were to present the recent key studies and evolution of lateral pelvic lymph node management in locally advanced rectal cancer and secondly to propose a management strategy for the lateral compartment based on the current evidence.

Abstract
4012 Background: Identification of tumor deposits (TD) currently plays a limited role in staging for colorectal cancer (CRC) other than for N1c designation. The aim of this study was to determine the prognostic impact, beyond AJCC N1c designation, of TD among primary CRC patients. Methods: Patients with stage 1 to 3 primary CRC diagnosed between 2010 and 2015 were identified from the Surveillance, Epidemiology and End Results (SEER) database. Cancer specific survival (CSS) stratified by TDs and nodal status was calculated, and Kaplan-Meier method and multivariable COX proportional hazards regression analyses were performed. Results: A total of 74,494 patients with primary CRC were identified. Mean age was 66.4 (SD+/-13.2) years, 36,988 (49.7%) were female and 40,651 (54.6%) were right-sided. TDs were present in 4,481 patients (6.0%) and 26,603 (35.7%) had lymph node metastases. The presence of TDs were significantly associated with adverse tumor characteristics including advanced pathological stage, nodal and metastasis status, higher grade and perineural invasion. Incorporating TDs into each nodal status was independently associated with worse CSS and supported reclassification of nodal status to incorporate TDs following multivariable regression analysis as outlined in the table. Following multivariable regression analysis, the proposed AJCC nodal reclassification incorporating TDs, in combination with tumor stage was a strong predictor of CSS, and also represents a new summary staging. Conclusions: TDs are an independent predictor of worse outcome in CRC. The presence of TDs have distinctly different CSS and these data support modification of the current N classification. This study proposes a reclassification of the AJCC system for CRC to incorporate TDs and informs an updated node and summary stage. [Table: see text]

Successful patient-oriented surgical outcomes in robotic vs laparoscopic right hemicolectomy for cancer - a systematic review. Colorectal Dis 2020; 22:488-499.

Abstract
AIM Minimally invasive surgical approaches for cancer of the right colon have been well described with significant patient and equivalent oncological benefits. Robotic surgery has advanced in its ability to provide multi-quadrant abdominal access, leading the surgical community to widen its application outside of the pelvis to other abdominal compartments. Globally it is being realized that a patient's surgical episode of care is becoming the epicentre of cancer treatment. In order to establish the role of robotic surgery in a patient's episode of care, 'successful patient-oriented surgical' parameters in right hemicolectomy for malignancy were measured. The objective was to examine the rates of successful patient-oriented surgical outcomes in robotic right hemicolectomy (RRH) compared to laparoscopic right hemicolectomy (LRH) for cancer. METHODS A systematic search of MEDLINE (Ovid: 1946-present), PubMed (NCBI), Embase (Ovid: 1966-present) and Cochrane Library was conducted using PRISMA for parameters of successful patient-oriented surgical outcomes in RRH and LRH for malignancy alone. The parameters measured included postoperative ileus, anastomotic complication, surgical wound infection, length of stay (LOS), incisional hernia rate, conversion to open, margin status, lymph node harvest and overall morbidity and mortality. RESULTS There were 15 studies which included 831 RRH patients and 3241 LRH patients, with a median age of 62-74 years. No study analysed the concept of successful patient-oriented surgical outcomes. There was no significant difference in the incidence of postoperative ileus, with less time to first flatus in RRH (2.0-2.7 days, compared with 2.5-4.0 days, P < 0.05). Anastomotic leak rate in one study reported a significant increase in LRH compared to RRH (P < 0.05, 0% vs 8.3%). Significantly decreased LOS following RRH was outlined in six studies. One study reported a significantly higher rate of incisional hernias following LRH with extracorporeal anastomoses compared to RRH with intracorporeal anastomoses. Overall rates of conversion to open surgery were less with RRH (0%-3.9% vs 0%-18%, P < 0.001, 0.05). One study outlined significantly higher rates of incomplete resection with an open right hemicolectomy compared with minimally invasive laparoscopic and robotic resections, with positive margin rates of 2.3%, 0.9% and 0% respectively (P < 0.001). Two studies reported significantly higher lymph node harvest in RRH (P < 0.05). Overall morbidity and 30-day mortality were comparable in both approaches. CONCLUSION Thirty-day morbidity and mortality were comparable between the two approaches, with patients undergoing RRH having lower anastomotic complications, increased lymph node harvest, and reduced LOS, conversion to open and incisional hernia rates in a number of studies. There are limited data on surgical approach and impact on quality of life and what patients deem successful surgical outcomes. There is a further need for a randomized controlled trial examining successful patient-oriented outcomes in right hemicolectomy for malignancy.

Abstract
INTRODUCTION Inadequate lymphadenectomy is still a major concern in colon cancer surgery. The superior mesenteric vein (SMV)-first approach is a novel, standardized, reproducible method for robotic complete mesocolic excision surgery. OBJECTIVE Our aim was to present the application of the SMV-first approach principles to facilitate robotic salvage surgery for recurrent disease within the mesocolon. METHODS A 78-year-old female presented with a malignant lymph node deposit within residual right mesocolonic tissue, approximately 3 months following a laparoscopic right hemicolectomy for colon cancer. Dissection was initiated with a transverse curvilinear incision along the inferior aspect of the remaining ileocolic pedicle to identify the SMV. Dissection continued along the ventral aspect of the SMV in a cephalad direction to identify and expose the middle colic vessels at their origin. The use of idocyanine green (ICG) confirmed the vascular anatomy, demonstrating the right branch of the middle colic artery traversing the malignant deposit in the residual mesocolon. Following ligation at the origin of the right branch of the middle colic and ileocolic vessels, the retro-mesocolic plane dissection was completed to excise the malignant deposit and the residual mesocolon. RESULTS The patient was discharged home the following day. The pathological specimen confirmed metastatic poorly differentiated adenocarcinoma in one of nine lymph nodes, and the vascular pedicle resection margin was negative for tumor. CONCLUSION Following the SMV-first approach principles provides a safe plane for dissection, and, in conjunction with ICG, facilitates the delineation of the vascular anatomy, to enable robotic salvage surgery to be performed.1-3.

Prophylactic biological mesh reinforcement versus standard closure of stoma site (ROCSS): a multicentre, randomised controlled trial. Lancet 2020; 395:417-426. [PMID: 32035551 PMCID: PMC7016509 DOI: 10.1016/s0140-6736(19)32637-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 10/11/2019] [Accepted: 10/18/2019] [Indexed: 12/24/2022]
Abstract
BACKGROUND Closure of an abdominal stoma, a common elective operation, is associated with frequent complications; one of the commonest and impactful is incisional hernia formation. We aimed to investigate whether biological mesh (collagen tissue matrix) can safely reduce the incidence of incisional hernias at the stoma closure site. METHODS In this randomised controlled trial (ROCSS) done in 37 hospitals across three European countries (35 UK, one Denmark, one Netherlands), patients aged 18 years or older undergoing elective ileostomy or colostomy closure were randomly assigned using a computer-based algorithm in a 1:1 ratio to either biological mesh reinforcement or closure with sutures alone (control). Training in the novel technique was standardised across hospitals. Patients and outcome assessors were masked to treatment allocation. The primary outcome measure was occurrence of clinically detectable hernia 2 years after randomisation (intention to treat). A sample size of 790 patients was required to identify a 40% reduction (25% to 15%), with 90% power (15% drop-out rate). This study is registered with ClinicalTrials.gov, NCT02238964. FINDINGS Between Nov 28, 2012, and Nov 11, 2015, of 1286 screened patients, 790 were randomly assigned. 394 (50%) patients were randomly assigned to mesh closure and 396 (50%) to standard closure. In the mesh group, 373 (95%) of 394 patients successfully received mesh and in the control group, three patients received mesh. The clinically detectable hernia rate, the primary outcome, at 2 years was 12% (39 of 323) in the mesh group and 20% (64 of 327) in the control group (adjusted relative risk [RR] 0·62, 95% CI 0·43-0·90; p=0·012). In 455 patients for whom 1 year postoperative CT scans were available, there was a lower radiologically defined hernia rate in mesh versus control groups (20 [9%] of 229 vs 47 [21%] of 226, adjusted RR 0·42, 95% CI 0·26-0·69; p<0·001). There was also a reduction in symptomatic hernia (16%, 52 of 329 vs 19%, 64 of 331; adjusted relative risk 0·83, 0·60-1·16; p=0·29) and surgical reintervention (12%, 42 of 344 vs 16%, 54 of 346: adjusted relative risk 0·78, 0·54-1·13; p=0·19) at 2 years, but this result did not reach statistical significance. No significant differences were seen in wound infection rate, seroma rate, quality of life, pain scores, or serious adverse events. INTERPRETATION Reinforcement of the abdominal wall with a biological mesh at the time of stoma closure reduced clinically detectable incisional hernia within 24 months of surgery and with an acceptable safety profile. The results of this study support the use of biological mesh in stoma closure site reinforcement to reduce the early formation of incisional hernias.

Abstract
64 Background: Patients with sporadic young-onset colorectal cancer (CRC) are postulated to have a more biologically active colorectum prone to malignant transformation earlier in life. It is unknown whether there is elevated risk for metachronous colorectal pathology after the index cancer. We aimed to define this risk, to inform their post-resection endoscopic surveillance. Methods: Consecutive CRC patients (aged 18-50, n = 728) were prospectively followed after surgical resection between 2009 and 2017. Patients presenting with hereditary CRC, recurrent disease, or without endoscopy follow-up were excluded. All endoscopy records were subjected to natural language processing and further reviewed. Metachronous colorectal pathology of interest included: high-risk adenoma (≥1cm in size, > 3 in number, or tubulovillious/high-grade dysplasia histology), second CRC, and endoscopically detectable local recurrence. Results: During a 48-month (median) follow-up, 457 patients underwent 1,192 person-years of colonoscopic follow-up. The median age at CRC diagnosis was 44 years. Disease arose from the proximal colon in 9.4%, distal colon in 23.0% and rectum in 67.6%, and was stages I/II in 191 (41.8%), III in 185 (40.4%), and IV in 81 (17.7%). The majority (95.8%) underwent segmental resection, while the remainder had extended resections for synchronous pathology not amendable to preoperative endoscopic clearance. The overall incidence of metachronous pathology was 32 per 1000 person-years: 31 patients developed high-risk adenomas (6.8%), 1 had a second CRC (0.2%), and 7 had luminal recurrences (1.5%). The median time to metachronous pathology was 13.9 (IQR: 11.8-33.1) months, with 21 (53.8%) detected between 12 and 48 months post-resection. Conclusions: For young-onset CRC survivors, the incidence of metachronous colorectal pathology was 32 per 1000 person-years of follow-up. Given the time pattern of detection, adding an interval colonoscopy between the current recommended post-resection surveillance at 12 and 48 months may be beneficial. [Table: see text]

Abstract
BACKGROUND Pelvic exenteration has increasingly been shown to improve disease-free and overall survival for patients with locally advanced pelvic malignancies. Squamous cell carcinoma (SCC) is the second most common pelvic malignancy requiring exenteration. OBJECTIVE The aim of this study was to report the clinical and oncological outcomes from patients treated with pelvic exenteration for anal and urogenital SCC from a single, high-volume unit. METHODS A review of a prospectively maintained database from 1991 to 2018 at a high-volume specialised institution was performed. Primary endpoints included R0 resection rates, local recurrence and overall survival (OS) rates. RESULTS From January 1999 to July 2018, 361 patients underwent pelvic exenteration of which 31 patients were identified with SCC (15 anal SCC, 16 urogenital SCC). The majority of patients were females (n = 24, 77.4%). Median age was 59 (range 35-81). Twenty-seven patients underwent resection with curative intent with an R0 resection rate of 81.5%. Four patients underwent a palliative procedure [R1 = 3 (8%), R2 = 1 (3.3%)]. Mean hospital length of stay was 32 days (range 8-122 days). Disease-free survival was significantly increased in anal SCC with no significant difference in OS compared to urogenital SCC (p = 0.03, p = 0.447 respectively). Advanced pathological T stage was associated with decreased OS (p = 0.023). In the curative intent group the disease-free survival and OS rate was 59.3% and 70% at 24 months, respectively. CONCLUSION Complete R0 resection is achievable in a high proportion of patients. Urogenital SCC is associated with significantly worse disease-free survival, and advanced T-stage was a significant prognostic factor for OS.

Abstract
Introduction: The safe introduction of transanal total mesorectal excision (taTME) has been documented by the Australasian group previously. The most important prognostic indicator for rectal cancer is the ability to achieve a clear resection margin. By utilizing false planes for taTME surgery, the endopelvic fascia and or presacral fascia can be resected en bloc. Technique: This case highlights the utilization of a taTME platform to perform a distal taTME with presacral fascial stripping and a lateral pelvic sidewall transanal-assisted dissection in a 53-year-old otherwise healthy woman with a mid-rectal tumor. Radiologically the tumor was staged as a T3c/T4 rectal cancer with an N1c deposit extending beyond mesorectal fascia abutting the left piriformis muscle. An extramural venous invasion positive tumor was evident with a positive circumferential resection margin at 4 o' clock. In addition, the taTME platform was used to allow transanal intraoperative radiotherapy (IORT) delivery to the sacrum. An R0 resection was achieved and the patient recovered well without incident. Results: Total operative time was 250 minutes with the patient being discharged on day 7 postoperatively without complication. Macroscopic evaluation revealed a grade III mesorectal excision with en bloc removal of presacral fascia. On microscopic evaluation, revealed a T3N1b tumor with 2 of 14 positive lymph nodes (0/5 pelvic sidewall nodes). Conclusion: The case highlights a novel application of taTME and is to the authors' best knowledge the first described use of a transanal platform to deliver intraoperative radiation therapy in the literature.
