65), TACE/TARE (p=0.35), resection (p=0.15) and transplantation (p=0.67) when compared to non-SCD patients. This study confirms that a subset of patients with SCD will develop HCC. Importantly, therapeutic options for HCC should not be limited by pre-existing SCD, and similar survival should be expected when compared to non-SCD patients.This study confirms that a subset of patients with SCD will develop HCC.

Intraoperative autologous transfusion (IAT) of salvaged blood is a common method of resuscitation during liver transplantation (LT), however concern for recurrence in recipients with hepatocellular carcinoma (HCC) has limited widespread adoption. A review of patients undergoing LT for HCC between 2008 and 2018 was performed. Clinicopathologic and intraoperative characteristics associated with inferior recurrence-free (RFS) and overall survival (OS) were identified using Kaplan-Meier analysis and uni-/multi-variable Cox proportional hazards modeling. Propensity matching was utilized to derive clinicopathologically similar groups for subgroup analysis. One-hundred-eighty-six patients were identified with a median follow up of 65 months. Transplant recipients receiving IAT (n=131, 70%) also had higher allogenic transfusions (median 5 versus 0 units, P<0.001). There were 14 recurrences and 46 deaths, yielding an estimated 10-year RFS and OS of 89% and 67%, respectively. IAT was not associated with RFS (HR 0.89/liter, P=0.60), or OS (HR 0.98/liter, P=0.83) pre-matching, or with RFS (HR 0.97/liter, P=0.92) or OS (HR 1.04/liter, P=0.77) in the matched cohort (n=49 per group). IAT during LT for HCC is not associated with adverse oncologic outcomes. Use of IAT should be encouraged to minimize the volume of allogenic transfusion in patients undergoing LT for HCC.IAT during LT for HCC is not associated with adverse oncologic outcomes.

Surgical resection is the mainstay of potential cure for patients with pancreatic cancer, however, local recurrence is frequent. Previously, we have described an extended resection technique for pancreatoduodenectomy aiming at a radical resection of the nerve and lymphatic tissue between celiac artery, superior mesenteric artery and mesenteric-portal axis (TRIANGLE operation). Until now, data on postoperative outcome have not been reported, yet. Patients who underwent either partial (PD) or total pancreatoduodenectomy (TP) applying the TRIANGLE procedure were identified. These cohorts were compared to matched historic cohorts with standard resections. Overall, 330 patients were analysed (PD and PD each n=108; TP and TP each n=57). More lymph nodes were harvested in TRIANGLE compared to standard resection (PD 27.5 (21-35) versus 31.5 (24-40); P=0.0187, TP 33 (28-49) versus 44 (29-53); P=0.3174) and the rate of tumour positive resections margins, R1(direct), dropped. Duration of operation was significantly longer and blood loss higher. Postoperative mortality and complications did not differ significantly. Pancreatoduodenectomy according to the TRIANGLE protocol can be performed without increased morbidity and mortality at a high-volume centre. Long-term survival and quality of life need to be investigated in prospective clinical trials with adequate sample size.Pancreatoduodenectomy according to the TRIANGLE protocol can be performed without increased morbidity and mortality at a high-volume centre.

Caroli Disease (CD) and Caroli Syndrome (CS) are rare disorders presenting with dilation of the intrahepatic bile ducts. Paclitaxel CD/CS are associated with cholangiocarcinoma (CCA). However, the true incidence of CCA is still unclear, although it may serve as an indication for surgery. In this paper, we analyzed (I) the incidence of CCA in German centers, (II) reviewed our single center population together with its clinical presentation and (III) performed a thorough literature review. 17 large HPB-centers across Germany were contacted and their patients after surgical treatment due to CD/CS with histopathology were included. Medline search for all studies published in English or German literature was performed. Patients who underwent surgery at our department between 2012 and 2020 due to CD or CS were analyzed. In the multicenter study, 79 patients suffered from CD and 119 patients from CS, with a total number of 198 patients. In 14 patients, CCA was found (Overall 7,1%; CD 6,3%, CS 7,6%). Between 2012 and 2020, 1661 liver resections were performed at our department. 14 patients underwent surgery due to CD or CS. Histological examination showed synchronous cholangiocarcinoma in one patient. The literature review revealed a CCA-rate of 7,3% in large series, whereas in case reports a rate of 6,8% was found. There is risk of malignant transformation and patients with CD might also benefit from resection due to improvement of symptoms. Therefore, resection is strongly advised. As certain patients with CS require transplantation, treatment should not be guided by the relatively low rate of CCA but by the concomitant diseases that come along with hepatic failure.There is risk of malignant transformation and patients with CD might also benefit from resection due to improvement of symptoms.

In particular, we focus on our interactions with academic researchers as a grassroots organization of criminalized people designing our own research. We describe the challenges we navigated to retain decision making powers over the research question, data analysis and interpretation, and dissemination. We find that our collaborations with academic researchers are often complicated by power imbalances and structural issues. In our experience as directly impacted people, even community based participatory research (CBPR) often sidelines us. Our eventual research approach demonstrates how our process transcends CBPR by becoming community driven research (CDR). We suggest several changes to the research process in order to propagate this model.
