- Abstract
Background: T1 rectal cancer (RC) patients are increasingly being treated by local resection alone but uniform surveillance strategies thereafter are lacking. To determine whether different local resection techniques influence the risk of recurrence and cancer-related mortality, a meta-analysis was performed. Methods: A systematic search was conducted for T1RC patients treated with local surgical resection. The primary outcome was the risk of RC recurrence and RC-related mortality. Pooled estimates were calculated using mixed-effect logistic regression. We also systematically searched and evaluated endoscopically treated T1RC patients in a similar manner. Results: In 2585 unique T1RC patients (86 studies) undergoing local surgical resection, the overall pooled cumulative incidence of recurrence was 9.1% (302 events, 95% CI 7.3–11.4%; I
2 = 68.3%). In meta-regression, the recurrence risk was associated with histological risk status (p< 0.005; low-risk 6.6%, 95% CI 4.4–9.7% vs. high-risk 28.2%, 95% CI 19–39.7%) and local surgical resection technique (p< 0.005; TEM/TAMIS 7.7%, 95% CI 5.3–11.0% vs. other local surgical excisions 10.8%, 95% CI 6.7–16.8%). In 641 unique T1RC patients treated with flexible endoscopic excision (16 studies), the risk of recurrence (7.7%, 95% CI 5.2–11.2%), cancer-related mortality (2.3%, 95% CI 1.1–4.9), and cancer-related mortality among patients with recurrence (30.0%, 95% CI 14.7–49.4%) were comparable to outcomes after TEM/TAMIS (risk of recurrence 7.7%, 95% CI 5.3–11.0%, cancer-related mortality 2.8%, 95% CI 1.2–6.2% and among patients with recurrence 35.6%, 95% CI 21.9–51.2%). Conclusions: Patients with T1 rectal cancer may have a significantly lower recurrence risk after TEM/TAMIS compared to other local surgical resection techniques. After TEM/TAMIS and endoscopic resection the recurrence risk, cancer-related mortality and cancer-related mortality among patients with recurrence were comparable. Recurrence was mainly dependent on histological risk status. Graphical abstract:- Published

Several factors are included in decision making for treatment of patients with locally advanced rectal cancer, including a trade-off between risks and gains of both clinical and functional outcomes. However, it is largely unknown which outcomes are most important to patients and whether this differs between patients and clinicians. Both clinicians and patients treated for locally advanced rectal cancer were invited to fill out an online questionnaire, including a choice-based conjoint experiment. Participants were presented 14 comparisons of two hypothetical case presentations, characterized by different treatments and outcomes of care (6 attributes) and were asked to select the case with the best outcome at that moment. Hierarchical Bayes Estimation was used to calculate the relative importance (RI) of each of the six attributes. In total, 94 patients and 128 clinicians completed the questionnaire. For patients, avoiding surgery with permanent stoma was most important (RI 24.4, 95%CI 21.88–26.87) and a 2-year difference in disease-free survival was least important (RI 5.6, 95%CI 4.9–6.2). Clinicians assigned highest importance to avoiding severe and daily worries about cancer recurrence (RI 30.7, 95%CI 29.1–32.4), while this was ranked 4th by patients (RI 17.9, 95%CI 16.5–19.4, p < 0.001). When confronted with different outcomes within one case description, patients find the duration of disease free survival the least important. In addition, considerable differences were found between the importance assigned by patients and clinicians to clinical and functional outcomes, most notably in avoiding surgery with permanent stoma and worries about recurrence.

- Abstract
ObjectiveNon-randomised studies suggest that endoscopic mucosal resection (EMR) is equally effective in removing large rectal adenomas as transanal endoscopic microsurgery (TEM), but EMR might be more cost-effective and safer. This trial compares the clinical outcome and cost-effectiveness of TEM and EMR for large rectal adenomas.DesignPatients with rectal adenomas ≥3 cm, without malignant features, were randomised (1:1) to EMR or TEM, allowing endoscopic removal of residual adenoma at 3 months. Unexpected malignancies were excluded postrandomisation. Primary outcomes were recurrence within 24 months (aiming to demonstrate non-inferiority of EMR, upper limit 10%) and the number of recurrence-free days alive and out of hospital.ResultsTwo hundred and four patients were treated in 18 university and community hospitals. Twenty-seven (13%) had unexpected cancer and were excluded from further analysis. Overall recurrence rates were 15% after EMR and 11% after TEM; statistical non-inferiority was not reached. The numbers of recurrence-free days alive and out of hospital were similar (EMR 609±209, TEM 652±188, p=0.16). Complications occurred in 18% (EMR) versus 26% (TEM) (p=0.23), with major complications occurring in 1% (EMR) versus 8% (TEM) (p=0.064). Quality-adjusted life years were equal in both groups. EMR was approximately €3000 cheaper and therefore more cost-effective.ConclusionUnder the statistical assumptions of this study, non-inferiority of EMR could not be demonstrated. However, EMR may have potential as the primary method of choice due to a tendency of lower complication rates and a better cost-effectiveness ratio. The high rate of unexpected cancers should be dealt with in further studies.

- Abstract
Objective:Abdominoperineal resection (APR) is associated with high incidence of surgical wound infections. The use of incisional negative-pressure wound therapy (iNPWT) is known to reduce wound infections for several surgical indications. The aim of this pilot study was to investigate the potential of a new portable negative-pressure therapy device on perineal wound healing in patients undergoing APR.Approach:A new single-use incisional negative-pressure therapy device was applied in 10 patients. A negative pressure of −80 mmHg was continued for 7 days postsurgery. Incidence of wound complications and time to wound healing were compared with a historical control group of 10 patients undergoing APR in 2014, treated with conventional wound care.Results:Patient characteristics were comparable in both groups. Mean 1.6 dressings were used per patient. A wound complication was diagnosed in seven patients versus six in the control group. Wound infections were diagnosed median 11.5 days after surgery, compared with 10.5 days in the control group. Duration of wound healing was shorter in the study group (median 8.5 weeks vs. 13 weeks).Innovation:This is the first study to report on the use of this iNPWT device for patients who underwent APR for rectal cancer.Conclusion:In this study, iNPWT did not reduce wound complications. Wound infections occurred slightly later and seemed to have a less severe clinical course. After treatment with iNPWT, the duration of wound healing was shorter.

- Abstract
Background and Aims Large non-pedunculated rectal polyps are most commonly resected by endoscopic mucosal resection (EMR) or transanal endoscopic microsurgery (TEM). Despite pre-procedural diagnostics, unexpected rectal cancer is incidentally encountered within the resected specimen. This study aimed to compare the diagnostic assessment and procedural characteristics of lesions with and without unexpected submucosal invasion. Methods A post-hoc analysis of a multicenter randomized trial (TREND study) was performed in which patients with a non-pedunculated rectal polyp of ≥3 cm without endoscopic suspicion of invasive growth were randomized between EMR and TEM. Results Unexpected rectal cancer was detected in 13% (27/203) of patients; 15 after EMR and 12 after TEM. Most consisted of low-risk T1 cancers (78%, n = 18). There were no differences in the diagnostic assessment between lesions with and without unexpected submucosal invasion. Diagnostic biopsies revealed similar rates of high-grade dysplasia (28% [7/25] vs 18% [26/144]). When compared with EMR of adenomas, EMR procedures of unexpected cancers had a lower success rate of submucosal lifting (60% vs 93%, P < .001), were more often assessed as endoscopically incomplete (33% vs 10%, P = .01), and were more frequently terminated prematurely (60% vs 8%, P = .001). Conclusions Diagnostic assessment of large non-pedunculated rectal polyps revealed similar characteristics between unexpected cancers and adenomas. Unexpected cancers during EMR were non-lifting in 40%, endoscopically assessed as incomplete in 33%, and terminated prematurely in 60%. In treatment-naive patients, these factors should raise suspicion of malignancy and need discussion in a multidisciplinary team meeting for decision on further treatment strategies.
