None of the three surgical strategies for synchronous colorectal liver metastases appeared inferior to the others.

PRRT treatment offers increased OS, PFS, EFS, and response to treatment compared to (131)I-MIBG therapy in patients with progressive/malignant PGLs.

IntroductionThere is accumulating clinical evidence that acute liver failure may be regularly associated with myocardial injury. To test this hypothesis in a standardized experimental setting, we used two porcine models of ALF.Material and methodsIn 14 domestic pigs ALF was induced by either a) surgical devascularization of the liver (DV group, n = 7), or b) partial (70-75%) hepatectomy and ischaemia/reperfusion of the liver remnant for 150 min (I/R group, n = 7). Four additional animals constituted the sham operation group. All animals were monitored for a 12-h period, at the end of which their hearts were harvested. Plasma troponin I (cTnI) and malondialdehyde (MDA) were measured before the operation (baseline) and at 6 h and 12 h postoperatively. The harvested hearts were histologically analysed, appointing a score from 0 (no injury) to 3 (maximum injury) to selected injury indicators.ResultsIn the sham group, all cTnI measurements and total myocardial injury score were zero in all animals. In both ALF groups, plasma cTnI levels increased by the 6th and remained elevated up to the 12th postoperative hour (p < 0.01 vs. sham animals). Total myocardial injury score and total histological score revealed some extent of myocardial injury. The rise of MDA levels suggests an underlying oxidative mechanism.ConclusionsOur study provides direct evidence of early myocardial injury in the setting of acute liver failure in pigs. The mechanism of injury remains to be elucidated.

Background/Aim: To date few cases of smooth muscle-derived tumors of the adrenal gland have been reported and their treatment remains a medical challenge. The aim of this manuscript was to systematically review the literature and present the tumor characteristics and their management in order to provide a standardized approach to their diagnosis and management. Materials and Methods: We searched five databases (PubMed, Scopus, Elsevier, ResearchGate, Google scholar) for relevant articles published until March 2020. Results: Twenty-two cases of adrenal leiomyoma, four cases of adrenal smooth muscle tumor and forty-five cases of adrenal leiomyosarcoma were included. Conclusion: We present the demographic, clinical, radiological, pathological and oncological characteristics and prognosis of tumors of the adrenal gland arising from smooth muscle cells, as well as describe the common clinical investigations and therapeutic modalities that have been reported as part of their management.Adrenal tumors can be detected either incidentally or after investigation of signs and symptoms that they evoke. Generally, they can be histologically categorized as primary tumors of the adrenal cortex or medulla, metastases from other primary malignancies and other tumors of the adrenal gland which originate from connective tissue cells. Adrenal cortical tumors are comprised by (asymmetric) adrenal cortical hyperplasia, adenoma, myelolipoma, adrenocortical carcinoma, oncocytic adrenocortical neoplasms; medullary tumors are comprised by pheochromocytoma, ganglioneuroma, neuroblastoma, ganglioneuroblastoma and teratoma. Connective tissue origin tumors are rarer and are comprised mainly by haemangioma and lymphangioma with a few cases of leiomyoma, lipoma, hemangiosarcoma, lymphoma, leiomyosarcoma and liposarcoma, as reported in the literature. Patients with primary malignancies in lung, breast, kidney, colon, oesophagus, pancreas, liver, stomach or with melanoma can present with adrenal metastases spread from these tumors, which can commonly be found bilaterally (1).Leiomyomas (LM) and leiomyosarcomas (LMS) are mesenchymal tumors that derive from smooth muscle cells. Their benign -leiomyoma or malignant -leiomyosarcoma characterization depends on nuclear atypia and/or pleomorphism, mitotic activity and tumor cell necrosis (2). Leiomyomas and leiomyosarcomas of the adrenal gland comprise a very small percentage of the gland's pathology with very little data available in the literature. The aim of this manuscript was to systematically review the literature and present demographic, clinical, radiological, pathological and oncological characteristics and prognosis of tumors of the adrenal gland arising from smooth muscle cells, as well as describe the common clinical investigations and therapeutic modalities that have been reported as part of their management.

This type of operation is less time-consuming and less invasive, since no further reconstruction of the alimentary tract or the vascular system is applied.
