Multidisciplinary Management of Hepatocellular Carcinoma Improves Access to Therapy and Patient Survival.

BACKGROUND: Given the complexity of managing hepatocellular carcinoma (HCC), it is widely accepted that a multidisciplinary team approach (tumor boards) offers the best approach to individualize therapy. The aim of this study was to determine utilization of therapies and outcomes for patients with HCC, comparing those managed through our multidisciplinary tumor board (MDTB) to those who were not. METHODS: A database analysis of all patients with HCC managed through our MDTB, from 2007 until 2011, was performed. A database of all patients with HCC from 2002 to 2011, not managed through MDTB, was similarly created. RESULTS: A total of 306 patients with HCC, from 2007 to 2011 were managed through our MDTB, in comparison with 349 patients, from 2002 to 2011 who were not. There were no significant differences in baseline demographic data or model for end-stage liver disease at presentation. Patients managed through MDTB were more likely to present at an earlier tumor stage and with lower serum alpha fetoprotein (AFP) (P=0.007). The odds of receiving any treatment for HCC was higher in patients managed through MDTB (odds ratio, 2.80; 95% confidence interval, 1.71-4.59; P<0.0001) independent of model for end-stage liver disease score, serum AFP, and tumor stage. There was significantly greater survival of patients managed through MDTB (19.1±2.5 vs. 7.6±0.9 mo, P<0.0001). Independent predictors for improved survival included management through MDTB, receipt of any HCC treatment, lower serum AFP, receipt of liver transplant, and T2 tumor stage. CONCLUSIONS: Patients with HCC managed through a MDTB had significantly higher rates of receipt of therapy and improved survival compared with those who were not.

Not as Rare as Initially Described: Transplant Ureter Incarceration Within Inguinal Hernia. Two Cases, Literature Review, and Management Algorithm.

BACKGROUND: Obstructive uropathy after kidney transplant can present as acute kidney injury, urosepsis, and more rarely kidney allograft failure. We present a recent series of 2 cases and a literature review of 1 late etiology of ureteric obstruction: incarceration of the transplant ureter within an inguinal hernia. METHODS: We reviewed 2 cases of patients with ureteric incarceration in an inguinal hernia after kidney transplant and conducted a contemporary structured literature review. Relevant patient factors, management decisions, operative approaches, and clinical outcomes were abstracted and summarized. RESULTS: Two cases of ureteric involvement in an inguinal hernia from 2 institutions as well as a literature review of 14 case reports are provided. The clinical features most commonly associated with this condition were male sex, obesity, and decade or more delay between kidney transplantation and presentation. Preoperative management with nephrostomy tube with or without antegrade ureteric stent was most frequently employed. Ultimately, most patients underwent surgical hernia repair, which occasionally required additional surgery for distal ureteric resection or re-anastomosis. CONCLUSIONS: Incarceration of a transplant allograft ureter in inguinal hernia is likely not as rare as initially described, although a true incidence rate has not been established. This surgically correctible condition most frequently presents as a late complication after kidney transplantation. We present a management algorithm that can be used for the workup and treatment of patients with history of kidney transplant who present with ureteric obstruction owing to incarceration within an inguinal hernia.

Predicting the Safe Use of Deceased After Circulatory Death Liver Allografts in Primary Sclerosing Cholangitis.

OBJECTIVES: The use of deceased after circulatory death liver allografts in patients with primary sclerosing cholangitis is controversial, given the increased risk of graft complications in patients with primary sclerosing cholangitis. We hypothesized that transplant of deceased after circulatory death livers into recipients with primary sclerosing cholangitis when appropriately selected using the UK deceased after circulatory death scoring system is not associated with increased graft failure and mortality. MATERIALS AND METHODS: We analyzed 99 229 transplants (between January 2001 and December 2018) from the Organ Procurement and Transplantation Network database. Deceased after circulatory death transplants were stratified by the UK scoring system as low risk or high risk. We identified 3958 patients with primary sclerosing cholangitis who received deceased after brain death transplant and 95 patients with primary sclerosing cholangitis who received deceased after circulatory death transplant. RESULTS: As expected, 5-year graft survival was lower in the circulatory death recipient group (69.0% vs 78.4%; P = .02). However, 5-year graft survival was significantly lower in the high-risk versus low-risk UK scoring system group (60.0% vs 75.4%; P = .02), with rate in the low-risk group similar to the brain death recipient group (78.4% vs 75.4%; P = .52). On multivariate analysis, the high-risk group had significantly increased risk of graft loss (hazard ratio of 1.92; P = .01). However, the low-risk group had equivalent graft survival to the brain death recipient group (hazard ratio of 1.23; P = .31). CONCLUSIONS: Graft failure was higher in patients with primary sclerosing cholangitis who received livers from deceased after circulatory death donors; however, the risk of graft loss was abrogated using appropriately matched donor and recipient combinations.

Post-transplant DSA monitoring may predict antibody-mediated rejection in sensitized kidney transplant recipients.

We examined whether changes in posttransplant highest intensity donor specific anti-HLA antibody specificity (DSAmax) measured by single antigen bead via Luminex (One Lambda, Inc.) were associated with antibody-mediated rejection (AMR). We conducted a retrospective analysis examining risk factors for AMR in 116 consecutive patients who underwent desensitization between 1/1/2009 and 9/1/2010. All patients had a negative flow cytometry crossmatch. The mean patient age at transplant was 46.4 +/- 4 years. The mean peak PRA (panel reactive antibody) and DSAmax at transplant were 40 +/- 6% and 894 +/- 150 mean fluorescent intensity (MFI), respectively. The mean time to rejection was 1.5 +/- 0.4 months. Cox regression analyses demonstrated that an increase in DSAmax by one week after transplant was significantly associated with AMR (pure or mixed). A rise in DSAmax greater than 500 MFI at 1 week was associated with a 2.6 times greater risk of rejection (HR 2.6, 95% CI 1.1 - 6.3, p = 0.02). We conclude that a rise in DSAmax at one week is an independent risk factor forAMR and that posttransplant DSA monitoring strategies may reduce the risk of AMR in sensitized patients.
