Show moreObjective: The aim of this study was to evaluate the safety and efficacy of a modified CAL-WR. Summary Background Data: The use of segmental colectomy in patients with endoscopically unresectable colonic lesions results in significant morbidity and mortality. CAL-WR is an alternative procedure that may reduce morbidity. Methods: This prospective multicenter study was performed in 13 Dutch hospitals between January 2017 and December 2019. Inclusion criteria were (1) colonic lesions inaccessible using current endoscopic resection techniques (judged by an expert panel), (2) non-lifting residual/recurrent adenomatous tissue after previous polypectomy or (3) an undetermined resection margin after endoscopic removal of a low-risk pathological T1 (pT1) colon carcinoma. Thirty-day morbidity, technical success rate and radicality were evaluated. Results: Of the 118 patients included (56% male, mean age 66 years, standard deviation +/- 8 years), 66 (56%) had complex lesions unsuitable for endoscopic removal, 34 (29%) had non-lifting residual/recurrent adenoma after previous polypectomy and 18 (15%) had uncertain resection margins after polypectomy of a pT1 colon carcinoma. CAL-WR was technically successful in 93% and R-0 resection was achieved in 91% of patients. Minor complications (Clavien-Dindo i-ii) were noted in 7 patients (6%) and an additional oncologic segmental resection was performed in 12 cases (11%). Residual tissue at the scar was observed in 5% of patients during endoscopic follow-up. Conclusions: CAL-WR is an effective, organ-preserving approach that results in minor complications and circumvents the need for major surgery. CAL-WR, therefore, deserves consideration when endoscopic excision of circumscribed lesions is impossible or incomplete. Show less

Show morePatients with Barcelona Clinic Liver Cancer intermediate stage hepatocellular carcinoma (HCC) theoretically are an excellent group to consider downstaging using locoregional therapy (LRT) since they do not have extrahepatic spread or vascular invasion. Once successful, this can change the treatment strategy from palliative to curative intention. Although downstaging therapy is suggested in guidelines, it is still not widely accepted. Moreover, studies on downstaging are mainly performed in high-incidence HCC countries. Therefore, our aim was to gain insight in therapeutic strategies in patients with intermediate stage HCC and their impact on intention-to-treat survival in a real-life setting in a low-incidence HCC country.We retrospectively analyzed data from the national Dutch HCC registry. From this database, consisting of 1409 patients with a diagnosis of HCC between 2005-2013 in 5 Dutch tertiary referral centers, we identified 165 patients with intermediate stage HCC. Out of these patients, 63 (38%) were not offered LRT, whereas 102 (62%) did receive LRT. Subsequently, 50 (49%) of the 102 patients who received LRT were successfully downstaged. Eleven patients (22% of successfully downstaged patients) eventually underwent liver transplantation. Cox regression analysis showed that a lower MELD score, an AFP value <100 ng/ml, successful downstaging and liver transplantation (all <= p = 0.01) were positively associated to overall survival.In conclusion, our results demonstrate that LRT is not routinely offered to intermediate stage HCC patients in the Netherlands. Nevertheless, we showed that patients with intermediate stage HCC who are successfully downstaged have a survival benefit compared to those who were not. Show less

Show moreBackground: Individuals with Lynch syndrome are at high risk for colorectal cancer (CRC). Regular colonoscopies have proven to decrease CRC incidence and mortality. However, colonoscopy is burdensome and interval CRCs still occur. Hence, an accurate, less-invasive screening method that guides the timing of colonoscopy would be of important value.Aim: To outline the performance of non-endoscopic screening modalities for Lynch-associated CRC and adenomas.Methods: Systematic literature search in MEDLINE and EMBASE to identify studies investigating imaging techniques and biomarkers for detection of CRC and adenomas in Lynch syndrome. The QUADAS-2 tool was used for the quality assessment of included studies.Results: Seven of 1332 screened articles fulfilled the inclusion criteria. Two studies evaluated either CT colonography or MR colonography; both techniques were unable to detect CRC and (advanced) adenomas <10 mm. The other five studies evaluated plasma methylated-SEPTIN9, faecal immunochemical test (FIT), faecal tumour DNA markers (BAT-26, hMLH1, p53, D9S171, APC, D9S162, IFNA and DCC) and faecal microbiome as screening modalities. Sensitivity for CRC varied from 33% (BAT-26) to 70% (methylated-SEPTIN9) to 91% (hMLH1). High specificity (94-100%) for CRC and/or adenomas was observed for methylated-SEPTIN9, FIT and BAT-26. Desulfovibrio was enriched in the stool of patients having adenomas. However, all these studies were characterised by small populations, high/unclear risk of bias and/or low prevalence of adenomas.Conclusions: Imaging techniques are unsuitable for colon surveillance in Lynch syndrome, whereas biomarkers are understudied. Having outlined biomarker research in Lynch-associated and sporadic CRC/adenomas, we believe that these non-invasive markers may hold potential (whether or not combined) for this population. As they could be of great value, (pre-)clinical studies in this field should be prioritised. Show less

Show moreObjective: Evaluation of the trends in incidence, diagnostics, treatment and survival of patients with hepatocellular carcinoma (HCC) in the Netherlands.Method: Data regarding incidence, diagnostics, primary treatment and survival of patients with HCC in the period 2009-2016 were obtained from the Netherlands Cancer Registry. Trends in incidence, diagnostics, various treatment modalities (except liver transplantation, due to inaccurate data) and regional treatment preferences were analysed. Survival was evaluated using Kaplan-Meier curves and multivariable Cox proportional hazard regression modelling.Results: In the period of 2009-2016, 3838 patients were diagnosed with HCC. A distinct decrease in the percentage of patients who underwent tumour biopsy was observed (from 51% in 2009-2010 to 42% in 2015-2016). Percentage of patients who underwent cancer treatment increased markedly (from 49% in 2009-2010 to 57% in 2015-2016), mainly because of an increasing use of resection and ablation. The number of hospitals where resections were performed or sorafenib treatment prescribed decreased slightly. The number of hospitals sporadically (<1 ablation per year) performing ablations increased. There were significant differences between regions in the application of resection, ablation and transarterial chemoembolisation /radioembolisation (p < 0.05 after 'case mix'-correction). One-, 3 and 5-year survival of patients with HCC significantly improved in the studied period. Receiving cancer treatment was associated with increased survival, whereas increasing age and an advanced tumour stage were both associated with decreased survival.Conclusion: From 2009 to 2016, patients with hepatocellular carcinoma more often received cancer treatment and their survival improved. There were significant differences in types of treatment between various regions. (C) 2020 Elsevier Ltd. All rights reserved. Show less
