4:03 PM Abstract No. 29 Streamlining Y90 in early stage hepatocellular carcinoma by eliminating the lung shunt study: analysis of a 403-patient cohort

Tc-99m macro-aggregated albumin (MAA) imaging to estimate hepato-pulmonary shunting (LSF) is required prior to radioembolization (Y90) to mitigate risks of radiation pneumonitis. We hypothesize that patients with hepatocellular carcinoma (HCC) within Milan criteria for liver transplant have negligible LSF. This would potentially allow eliminating MAA studies when treating this cohort of HCC patients with Y90.

Abstract BACKGROUND: Hepatocellular carcinoma (HCC) recurrence and development of de novo malignancy (DNM) after liver transplantation (LT) are the major causes of late recipient death. METHODS: We analyzed the incidence of extrahepatic DNM following living donor LT according to the status of pretransplant hepatic malignancy. We selected 2,076 adult patients who underwent primary LDLT during 7 years from January 2010 to December 2016. RESULTS: The pretransplant hepatic malignancy group (n = 1,012) showed 45 cases (4.4%) of the following extrahepatic DNMs: posttransplant lymphoproliferative disease (PTLD)...

Abstract OBJECTIVES: In the Asian population, patterns and risk factors for de novo malignancies after solid-organ transplant are not well understood. MATERIALS AND METHODS: Insurance claims from Taiwan's National Health Institute Research Database from 1997 to 2011 revealed 687 deceased-donor heart transplant recipients, 5038 kidney transplant recipients (50% living related-donor, 50% deceased-donor transplants), and 2127 liver transplant recipients (mainly living related-donor transplants, 30% deceased-donor transplants). During the follow-up period, rates of malignancy incidence were calculated with standa...

ConclusionThe incidence of de novo malignancy was 1% at a median follow up of 42 (32-73) months. De novo malignancies following LDLT, although uncommon, are associated with significant mortality. A careful screening protocol should be followed post transplantation for early detection of de novo malignancies.

In conclusion, the patients with PTM had comparable outcomes with regard to mortality and cancer-specific mortality compared with those without PTM. This study showed that the patients with PTM can obtain an acceptable outcome after LDLT when carefully selected. PMID: 32023575 [PubMed - as supplied by publisher]

Rationale: Liver transplantation (LT) is the preferred surgical option for the treatment of early hepatocellular carcinoma (HCC). In contrast, surgical treatment of progressive HCC metastasized to the spine following LT constitutes a considerable challenge. Here, we report the first case of progressive HCC metastasized to the T12 vertebra after local radiotherapy, treated successfully with en bloc lumpectomy following LT for HCC. Patient concerns: A 40-year-old man who had undergone LT for the treatment of HCC 2 months prior presented to our clinic with symptoms of progressive back pain. Magnetic resonance imagining (...

Abstract BACKGROUND: Tumor recurrence after orthotopic liver transplantation (OLT) remains a serious threat for long-term survival of the recipients with hepatocellular carcinoma (HCC), since very few factors or measures have shown impact on overcoming HCC recurrence after OLT. Postoperative infection suppresses tumor recurrence and improves patient survival in lung cancer and malignant glioma probably via stimulating the immune system. Post-transplant infection (PTI), a common complication, is deemed to be harmful for the liver transplant recipients from a short-term perspective. Nevertheless, whether PTI inhibit...

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

We describe a case of a 56-year-old man who underwent liver transplant for hepatocellular carcinoma in a cirrhotic liver. Two years after liver tranplant, regular follow-up revealed metastatic disease in the left adrenal gland. Preoperative imaging showed no other metastasis, and he underwent an uneventful left adrenalectomy. A year after surgery, he presented with right flank pain and tenderness. Imaging showed hemorrhage and tumor involvement of the right adrenal gland, and he underwent right adrenalectomy. Two years after surgery, he is alive and well with no signs of disease recurrence. Apparently, in the absence of in...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

In humans, almost 50% of all intrahepatic lymphocytes are NK cells that are strongly imprinted in a liver-specific manner and show a broad spectrum of cellular heterogeneity.
