Abstract

Purpose: Minimally invasive right hemicolectomy (MIRH) is the cornerstone of treatment for patients with right-sided colon cancer. This operation has evolved during recent decades, with many innovations and improvements but this has also resulted in high variability of uptake with subsequent substantial variableness. The aim of this ongoing study is to identify current surgical variations, determine the most optimal and standardised MIRH and nationally train and implement that technique to improve short-term clinical and long-term oncological outcomes. Methods: The Right study is a national multicentre prospective interventional sequential cohort study. Firstly, current local practice was evaluated. Subsequently, a standardised surgical technique for right-sided colon cancer was determined using the Delphi consensus method, and this procedure was trained during hands-on courses. The standardised MIRH will be implemented with proctoring (implementation cohort), after which the performance will be monitored (consolidation cohort). Patients who will receive a minimally invasive (extended) right hemicolectomy for cT1-3N0-2M0 colon cancer will be included. The primary outcome is patient safety reflected in the 90-day overall complication rate according to the Clavien–Dindo classification. Secondary outcomes will include intraoperative complications, 90-day mortality rate, number of resected tumour-positive lymph nodes, completeness of mesocolic excision, surgical quality score, locoregional and distant recurrence and 5-year overall survival. A total number of 1095 patients (365 per cohort) will be included. Discussion: The Right study is designed to safely implement the best surgical practice concerning patients with right-sided colon cancer aiming to standardise and improve the surgical quality of MIRH at a national level. Trial registration: ClinicalTrials.gov: NCT04889456, May 2021. [ABSTRACT FROM AUTHOR]

Abstract

Background The widespread nature of coronavirus disease 2019 (COVID-19) has been unprecedented. We sought to analyze its global impact with a survey on colorectal cancer (CRC) care during the pandemic. Methods The impact of COVID-19 on preoperative assessment, elective surgery, and postoperative management of CRC patients was explored by a 35-item survey, which was distributed worldwide to members of surgical societies with an interest in CRC care. Respondents were divided into two comparator groups: 1) ‘delay’ group: CRC care affected by the pandemic; 2) ‘no delay’ group: unaltered CRC practice. Results A total of 1,051 respondents from 84 countries completed the survey. No substantial differences in demographics were found between the ‘delay’ (745, 70.9%) and ‘no delay’ (306, 29.1%) groups. Suspension of multidisciplinary team meetings, staff members quarantined or relocated to COVID-19 units, units fully dedicated to COVID-19 care, personal protective equipment not readily available were factors significantly associated to delays in endoscopy, radiology, surgery, histopathology and prolonged chemoradiation therapy-to-surgery intervals. In the ‘delay’ group, 48.9% of respondents reported a change in the initial surgical plan and 26.3% reported a shift from elective to urgent operations. Recovery of CRC care was associated with the status of the outbreak. Practicing in COVID-free units, no change in operative slots and staff members not relocated to COVID-19 units were statistically associated with unaltered CRC care in the ‘no delay’ group, while the geographical distribution was not. Conclusions Global changes in diagnostic and therapeutic CRC practices were evident. Changes were associated with differences in health-care delivery systems, hospital’s preparedness, resources availability, and local COVID-19 prevalence rather than geographical factors. Strategic planning is required to optimize CRC care., Global changes in both diagnostic and therapeutic practices in colorectal cancer care were evident in this survey conducted to analyze the impact of COVID-19 outbreak. The importance of this finding is that changes were associated with differences in health care delivery systems, hospital’s preparedness, resources availability, and local COVID-19 prevalence rather than geographical variations.

Abstract

Abstract Background Currently, the TNM classification of malignant tumours based on clinicopathological staging remains the standard for colorectal cancer (CRC) prognostication. Recently, we identified the mitochondrial oxidative phosphorylation chain as a consistently overrepresented category in the published gene expression profiling (GEP) studies on CRC prognosis. Methods We evaluated associations of putative regulatory single nucleotide polymorphisms (SNPs) in genes from the oxidative phosphorylation chain with survival and disease prognosis in 613 CRC patients from Northern Germany (PopGen cohort). Results Two SNPs in the 3′ untranslated region of UQCRB (complex III), rs7836698 and rs10504961, were associated with overall survival (HR = 0.52, 95% CI 0.32–0.85 and HR = 0.64, 95% CI 0.42–0.99, for TT carriers). These associations were restricted to the group of patients with cancer located in the colon (HR = 0.42, 95% CI 0.22–0.82 and HR = 0.46, 95% CI 0.25–0.83). Multivariate analysis indicated that both markers might act as independent prognostic markers. Additionally, the TT carriers were ~2 times more likely to develop tumours in the colon than in the rectum. Two SNPs in COX6B1 (complex IV) were associated with lymph node metastasis in a dominant model (rs6510502, OR = 1.75, 95% CI 1.20–2.57; rs10420252, OR = 1.68, 95% CI 1.11–2.53); rs6510502 was associated also with distant metastasis (OR = 1.67, 95% CI 1.09–2.56 in a dominant model). Conclusions This is the first report suggesting that markers in genes from the mitochondrial oxidative chain might be prognostic factors for CRC. Additional studies replicating the presented findings are needed.

Abstract

Background: Gallstone disease is a frequent and economically highly relevant disorder, with cholecystectomy representing one of the most frequently performed operations world-wide. Gallstone recurrence after cholecystectomy is associated with complications such as biliary sepsis and pancreatitis. As yet, variant ABCG8-D19H is the most widely recognized genetic risk factor for gallstone disease. The aim of the study is to investigate whether ABCG8-D19H is associated with gallstone recurrence after cholecystectomy. Methods: Two thousand three hundred and eight patients from an earlier study of gallstone risk factors were re-contacted by mail, leading to 1,915 patients with available clinical and genetic information. Symptomatic gallstone recurrence was established if it occurred more than six months after surgery. Median follow-up time after cholecystectomy was eight years. Results: Gallstones recurred in 37 patients (1.9 %). ABCG-D19H was found to be significantly associated with gallstone recurrence ( p = 0.034). The allelic odds ratio was 1.97 (95 % CI 1.12-∞). In a multivariate logistic regression analysis adjusted for age, sex, BMI and type of surgery, ABCG8-D19H remained a significant predictor, both in the total cohort ( p = 0.024) and in the subgroup for whom information on type and scheduling of surgery was available ( N = 1,650, p = 0.020). Conclusions: ABCG8-D19H is a predictor of gallstone recurrence, a major long term postoperative biliary complication. Moreover, the observed association also reemphasizes the importance of the sterolin transporter for stone formation. [ABSTRACT FROM AUTHOR]

Abstract

Background/aims: Quantification of α1-fetoprotein (AFP) mRNA in the blood using reverse transcriptase polymerase chain reaction (RT-PCR) could be a useful tool in monitoring the dynamics of minimal residual disease in patients with hepatocellular carcinoma (HCC). Since all available assays do not take into account the efficiency of cell separation, RNA extraction and reverse transcription, a competitive RT-PCR assay for quantification of AFP mRNA in relation to the housekeeping gene glyceraldehyde phosphate dehydrogenase (GAPDH) was established. Patients and methods: Peripheral blood of 22 patients and bone marrow aspirates of 11 patients with hepatocellular carcinoma was monitored perioperatively. Eighteen patients with other hepatic tumours or non-malignant hepatic diseases and 26 healthy blood donors served as controls. Messenger RNA contents were calculated relative to the content of GAPDH mRNA as an indicator of total cell count. Results: Among HCC patients, 6 of 22 (26%) were positive for AFP mRNA before operation with values ranging from 2 ag/100 fg to 36 ag/100 fg GAPDH mRNA (mean 14). Among bone marrow samples, AFP mRNA was detectable in 5 of 11 (45%) cases, with 4 ag/100 fg to 23 ag/100 fg GAPDH (mean 9). However, AFP mRNA was also detectable in 3 of 18 (17%) control patients and in 2 of 26 (8%) healthy blood donors. Perioperative findings were highly variable. Conclusion: AFP mRNA is not a specific marker for circulating malignant hepatocytes. Whether definition of a cut-off level or the use of a multimarker-PCR will provide more useful data remains to be established. [ABSTRACT FROM AUTHOR]

Abstract

Background/Aims: Adult bone marrow contains progenitors capable of generating hepatocytes. Here a new liver failure model is introduced to assess whether bone marrow-derived progeny contribute to liver regeneration after acute hepatotoxic liver failure.Methods: Retrorsine was used to inhibit endogenous hepatocyte proliferation, before inducing acute liver failure by carbon tetrachloride. Bone marrow chimeras were generated before inducing liver failure to trace bone marrow-derived cells. Therefore, CD45 and major histocompatibility complex (MHC) class I dimorphic rat models were applied.Results: Early after acute liver failure a multilineage inflammatory infiltrate was observed, mainly consisting of granulocytes. In long-term experiments small numbers of CD90+/CD45− cells of donor origin occurred in clusters associated with portal triads. Bone marrow cell infusion was not able to enhance liver regeneration. Cellular hypertrophy was the predominant way of liver mass regeneration in models applying retrorsine.Conclusions: Retrorsine pretreatment did not affect sensitivity for carbon tetrachloride. A multilineage inflammatory infiltrate was observed in rats whether pretreated with retrorsine or not. Few donor cells co-expressing CD90 (THY 1) were present in recipient livers, which may resemble donor-derived hematopoietic progenitors or oval cells. No other donor cells within liver parenchyma were detected. This is in contrast to other cell infusion models of acute cell death. [Copyright &y& Elsevier]

Abstract

Background: Today, most of the pre-emptive hemodynamic optimization algorithms are based on variables associated with invasive techniques like arterial cannulation. The non-invasive Nexfin™ technology is able to estimate continuous Cardiac Index (CI) and pulse pressure variation (PPV). However, the efficiency of an early goal directed therapy (EGDT) algorithm based on non-invasive variables has to be proven. The aim of our study was to investigate the feasibility of a non-invasive driven EGDT protocol and its impact on patient's outcome., Methods: Seventy-nine patients (ASA II-III) undergoing elective major abdominal surgery were randomized to either study group (SG, N.=39) or control group (CG, N.=40). The SG was treated according to an algorithm based on non-invasive CI and PPV, whereas the CG received standard of care. Postoperative complications up to 28 days and length of hospital stay (LOS) in both groups were recorded., Results: There was no significant difference between the groups regarding demographics, hemodynamic variables, preoperative risk scores and duration of surgery. The total amount of complications was higher in the CG (SG 94 vs. CG 132 complications, P=0.22) without reaching statistical significance. LOS revealed no difference between both groups (SG, 9 [7-15] vs. CG, 9 [7-15.25] days, P=0.82). We have seen no impact of the non-invasive optimization protocol with respect to postoperative mortality., Conclusions: In this patient collective, we could demonstrate the feasibility of a non-invasive approach for hemodynamic optimization. However, EGDT based on non-invasive variables was not able to significantly improve outcome.
