- Epithelioid hemangioendothelioma (EHE) is an ultra-rare, translocated, vascular sarcoma. EHE clinical behavior is variable, ranging from that of a low-grade malignancy to that of a high-grade sarcoma and it is marked by a high propensity for systemic involvement. No active systemic agents are currently approved specifically for EHE, which is typically refractory to the antitumor drugs used in sarcomas. The degree of uncertainty in selecting the most appropriate therapy for EHE patients and the lack of guidelines on the clinical management of the disease make the adoption of new treatments inconsistent across the world, resulting in suboptimal outcomes for many EHE patients. To address the shortcoming, a global consensus meeting was organized in December 2020 under the umbrella of the European Society for Medical Oncology (ESMO) involving >80 experts from several disciplines from Europe, North America and Asia, together with a patient representative from the EHE Group, a global, disease-specific patient advocacy group, and Sarcoma Patient EuroNet (SPAEN). The meeting was aimed at defining, by consensus, evidence-based best practices for the optimal approach to primary and metastatic EHE. The consensus achieved during that meeting is the subject of the present publication.

- Background: Access to the liver transplant waitlist for patients with hepatocellular carcinoma (HCC) depends on tumour presentation, biology, and response to treatments. The Milan Criteria (MC) represent the benchmark for expanded criteria that incorporate additional prognostic factors. The purpose of this study was to determine the added value of skeletal muscle index (SMI) in HCC patients beyond the MC. Method: Patients with HCC that were transplanted beyond the MC were included in this retrospective multicentre study. SMI was quantified using the Computed Tomography (CT) within 3months prior to transplantation. Cox regression models were used to identify predictors of overall survival (OS). The discriminative performance of SMI extended Metroticket 2.0 and AFP models was also assessed. Results: Out of 889 patients transplanted outside the MC, 528 had a CT scan within 3months prior to liver transplantation (LT), of whom 176 (33%) were classified as sarcopenic. The median time between assessment of the SMI and LT was 1.8months (IQR: 0.77–2.67). The median follow-up period was 5.1 95% CI [4.7–5.5] years, with a total of 177 recorded deaths from any cause. In a linear regression model with SMI as the dependent variable, only male gender (8.55 95% CI [6.51–10.59], P<0.001) and body mass index (0.74 95% CI [0.59–0.89], P<0.001) were significant. Univariable survival analysis of patients with sarcopenia versus patients without sarcopenia showed a significant difference in OS (HR 1.44 95% CI [1.07−1.94], P=0.018). Also the SMI was significant (HR 0.98 95% CI [0.96–0.99], P=0.014). The survival difference between the lowest SMI quartile versus the highest SMI quartile was significant (log-rank: P=0.005) with 5year OS of 57% and 71%, respectively. Data from 423 patients, describing 139 deaths, was used for multivariate analysis. Both sarcopenia (HR 1.45 95% CI [1.02−2.05], P=0.036) and SMI were (HR 0.98 95% CI [0.95–0.99], P=0.035) significant. On the survival scale this translates to a 5year OS difference of 11% between sarcopenia and no sarcopenia. Whereas for SMI, this translates to a survival difference of 8% between first and third quartiles for both genders. Conclusions: Overall, we can conclude that higher muscle mass contributes to a better long-term survival. However, for individual patients, low muscle mass should not be considered an absolute contra-indication for LT as its discriminatory performance was limited.

- Objective: To define benchmark cutoffs for redo liver transplantation (redo-LT). Background: In the era of organ shortage, redo-LT is frequently discussed in terms of expected poor outcome and wasteful resources. However, there is a lack of benchmark data to reliably evaluate outcomes after redo-LT. Methods: We collected data on redo-LT between January 2010 and December 2018 from 22 high-volume transplant centers. Benchmark cases were defined as recipients with model of end stage liver disease (MELD) score <= 25, absence of portal vein thrombosis, no mechanical ventilation at the time of surgery, receiving a graft from a donor after brain death. Also, high-urgent priority and early redo-LT including those for primary nonfunction (PNF) or hepatic artery thrombosis were excluded. Benchmark cutoffs were derived from the 75th percentile of the medians of all benchmark centers. Results: Of 1110 redo-LT, 373 (34%) cases qualified as benchmark cases. Among these cases, the rate of postoperative complications until discharge was 76%, and increased up to 87% at 1-year, respectively. One-year overall survival rate was excellent with 90%. Benchmark cutoffs included Comprehensive Complication Index CCI (R) at 1-year of <= 72, and in-hospital and 1-year mortality rates of <= 13% and <= 15%, respectively. In contrast, patients who received a redo-LT for PNF showed worse outcomes with some values dramatically outside the redoLT benchmarks. Conclusion: This study shows that redo-LT achieves good outcome when looking at benchmark scenarios. However, this figure changes in high-risk redo-LT, as for example in PNF. This analysis objectifies for the first-time results and efforts for redo-LT and can serve as a basis for discussion about the use of scarce resources.

- Background & Aims: Management of combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is not well-defined. Therefore, we evaluated the management of cHCC-CCA using an online hospital-wide multicentre survey sent to expert centres.Methods: A survey was sent to members of the European Network for the Study of Cholangiocarcinoma (ENS-CCA) and the International Cholangiocarcinoma Research Network (ICRN), in July 2021. To capture the respondents' contemporary decision making process, a hypothetical case study with different tumour size and number combinations was embedded.Results: Of 155 surveys obtained, 87 (56%) were completed in full and included for analysis. Respondents represented Europe (68%), North America (20%), Asia (11%), and South America (1%) and included surgeons (46%), oncologists (29%), and hepatologists/gastroenterologists (25%). Two-thirds of the respondents included at least one new patient with cHCC-CCA per year. Liver resection was reported as the most likely treatment for a single cHCC-CCA lesion of 2.0-6.0 cm (range: 73-93%) and for two lesions, one up to 6 cm and a second well-defined lesion of 2.0 cm (range: 60-66%). Nonetheless, marked interdisciplinary differences were noted. Surgeons mainly adhered to resection if technically feasible, whereas up to half of the hepatologists/gastroenterologists and oncologists switched to alternative treatment options with increasing tumour burden. Fifty-one (59%) clinicians considered liver transplantation as an option for patients with cHCC-CCA, with the Milan criteria defining the upper limit of inclusion. Overall, well-defined cHCC-CCA treatment policies were lacking and management was most often dependent on local expertise.Conclusions: Liver resection is considered the first-line treatment of cHCC-CCA, with many clinicians supporting liver transplantation within limits. Marked interdisciplinary differences were reported, depending on local expertise. These findings stress the need for a well-defined multicentre prospective trial comparing treatments, including liver transplantation, to optimise the therapeutic management of cHCC-CCA.Impact and implications: Because the treatment of combined hepatocellular-cholangiocarcinoma (cHCC-CCA), a rare form of liver cancer, is currently not well-defined, we evaluated the contemporary treatment of this rare tumour type through an online survey sent to expert centres around the world. Based on the responses from 87 clinicians (46% surgeons, 29% oncologists, 25% hepatologists/gastroenterologists), representing four continents and 25 different countries, we found that liver resection is considered the first-line treatment of cHCC-CCA, with many clinicians supporting liver transplantation within limits. Nonetheless, marked differences in treatment decisions were reported among the different specialties (surgeon vs. oncologist vs. hepatologist/ gastroenterologist), highlighting the urgent need for a standardisation of therapeutic strategies for patients with cHCC-CCA.

- Background: The use of immunotherapy for cancer is increasing and is expected to continue growing. The outcomes after solid organ transplantation(SOT) in patients who received immunotherapy before SOT remain unclear. We evaluated the global transplant surgery community's attitude towards and experience with patients who received immunotherapy for malignancy before SOT. Methods: An online-based survey was sent to North American transplant program directors in December-2020 and members of the International Liver Transplant Society in November-2021 evaluating experiences with and attitudes towards SOT in recipients with previous immunotherapy for cancer. Results: A total of 119 respondents completed the survey(119/175;completion rate:68%), representing centers from North America, South America, Europe, Asia, and Australia. Seventy-one(62%) respondents would consider SOT in patients with a previous history of immunotherapy for cancer, whereas thirty-nine(34%) were aware of such immunotherapy-treated recipients being transplanted, with an increasing trend over the last few years(2016 [n = 1]-2020[n = 14]). Institutional clinical management policies in this setting were lacking in most centers(n = 85[75%]). Conclusions: The international transplant community is receptive to transplanting transplant candidates previously treated with immunotherapy for cancer, although experience is still limited. In this context, more centers have started to offer SOT to patients with a history of immunotherapy for cancer in recent years. However, support from clear and robust institutional policies in this endeavor is scant. Therefore, there is a high need for consensus guidelines to inform future clinical management, especially as immunotherapy for cancer is likely to continue to increase in the coming years.

Long-term outcomes of ablation, liver resection, and liver transplant as first-line treatment for solitary HCC of 3 cm or less using an intention-to-treat analysis : A retrospective cohort study
- 2022

Ingår i: Annals of Medicine and Surgery. - : Elsevier. - 2049-0801. ; 77

Tidskriftsartikel (refereegranskat)abstract
- Background: Curative-intent therapies for hepatocellular carcinoma (HCC) include radiofrequency ablation (RFA), liver resection (LR), and liver transplantation (LT). Controversy exists in treatment selection for earlystage tumours. We sought to evaluate the oncologic outcomes of patients who received either RFA, LR, or LT as first-line treatment for solitary HCC < 3 cm in an intention-to-treat analysis.Materials and methods: All patients with solitary HCC < 3 cm who underwent RFA, LR, or were listed for LT between Feb-2000 and Nov-2018 were analyzed. Cox regression analysis was then performed to compare intention-to-treat (ITT) survival by initial treatment allocation and disease-free survival (DFS) by treatment received in patients eligible for all three treatments.Results: A total of 119 patients were identified (RFA n = 83; LR n = 25; LT n = 11). The overall intention-to-treat survival was similar between the three groups. The overall DFS was highest for the LT group. This was significantly higher than RFA (p = 0.02), but not statistically significantly different from LR (p = 0.14). After multivariable adjustment, ITT survival was similar in the LR and LT groups relative to RFA (LR HR:1.13, 95%CI 0.33-3.82; p = 0.80; LT HR:1.39, 95%CI 0.35-5.44; p = 0.60). On multivariable DFS analysis, only LT was better relative to RFA (LR HR:0.52, 95%CI 0.26-1.02; p = 0.06; LT HR:0.15, 95%CI 0.03-0.67; p = 0.01). Compared to LR, LT was associated with a numerically lower hazard on multivariable DFS analysis, though this did not reach statistical significance (HR 0.30, 95%CI 0.06-1.43; p = 0.13)Conclusion: For treatment-naive patients with solitary HCC < 3 cm who are eligible for RFA, LR, and LT, adjusted ITT survival is equivalent amongst the treatment modalities, however, DFS is better with LR and LT, compared with RFA. Differences in recurrence between treatment modalities and equipoise in ITT survival provides support for a future prospective trial in this setting.

- To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d'Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2-129.4) months. Median follow-up from HCC recurrence was 12.2 (range 0.1-112.5) months. At recurrence, 31.4 % were treated with curative-intent treatments (surgery or ablation), 42.1 % received palliative treatment, and 26.4 % received best supportive care. The 1-, 3-, and 5-year survivals, respectively, after HCC recurrence were 75, 60, and 31 %, vs. 60, 19, and 12 %, vs. 52, 4, and 5 % (p < 0.001). By multivariate analysis, not being amenable to a curative-intent treatment [hazard ratio (HR) 4.7, 95 % confidence interval (CI) 2.7-8.3, p < 0.001], alpha-fetoprotein of a parts per thousand yen100 ng/mL at the time of HCC recurrence (HR 2.1, 95 % CI 1.3-2.3, p = 0.002) and early recurrence (< 12 months) after LT (HR 1.6, 95 % CI 1.1-2.5, p = 0.03) were found to be poor prognosis factors. A prognostic score was devised on the basis of these three independent variables. Patients were divided into three groups, as follows: good prognosis, 0 points (n = 22); moderate prognosis, 1 or 2 points (n = 84); and poor prognosis, 3 points (n = 15). The 1-, 3-, and 5-year actuarial survival for each group was 91, 50, and 50 %, vs. 52, 7, and 2 %, vs. 13, 0, and 0 %, respectively (p < 0.001). Patients with HCC recurrence after transplant amenable to curative-intent treatments can experience significant long-term survival (similar to 50 % at 5 years), so aggressive management should be offered. Poor prognosis factors after recurrence are not being amenable to a curative-intent treatment, alpha-fetoprotein of a parts per thousand yen100 ng/mL, and early (< 1 year) recurrence after LT.
