Will Patients With Liver Metastasis From Aggressives Cancers Benefit From Surgical Resection?

Background: We aimed to evaluate the outcomes of resections for liver metastases (LMs) originating from pancreatic ductal adenocarci-noma (PDAC), non-small cell lung cancer (NSCLC), and esophagus/ gastric cancers (EGCs), which we label as major killers (MKs; overall survival (OS) under 10%). We hypothesized that LM resection must provide the patient with almost a year of OS postoperatively that is considered beneficial. Methods: From January 2005 to December 2020, 23 patients under-went resection for isolated LM from MKs. These patients underwent surgery after a multidisciplinary discussion about their performance status, disease evolution during prolonged medical treatment, and the existence or absence of extrahepatic metastases. Results: LM originated from an PDAC, EGC, or NSCLC in 10 pa-tients (43%), nine patients (39%), and four patients (18%), respective-ly. The median delay between primary cancer and LM diagnoses was 12 months, and the median delay between LM diagnosis and liver re-section was 10 months. Most patients, who had objectively responded to medical treatment (57%), had a solitary (61%) and unilobar (70%) LM. Severe morbidity and 90-day mortality rates were 13% and 4.3%, respectively. Margin-free resection was achieved in 16 patients (70%). After liver resection, the median OS was 24 months without a statistical difference when considering the primary tumor site; 1, 3-, and 5-year OS were 70%, 23%, and 23%, respectively. Conclusion: Selection based on criteria such as good clinical condi-tion, response to treatment, and long observation period helped iden-tify patients with LM of MKs who seemed to benefit from resection

Future remnant liver optimization: preoperative assessment, volume augmentation procedures and management of PVEfailure

© 2022 Edizioni Minerva Medica. All rights reserved.Surgery is the cornerstone treatment for patients with primary or metastatic hepatic tumors. Thanks to surgical and anesthetic technological advances, current indications for liver resections have been significantly expanded to include any patient in whom all disease can be resected with a negative margin (R0) while preserving an adequate future residual liver (FRL). Posthepatectomy liver failure (PHLF) is still a feared complication following major liver surgery, associated with high morbidity, mortality and cost implications. PHLF is mainly linked to both the size and quality of the FRL. Significant advances have been made in detailed preoperative assessment to predict and mitigate this complication, even if an ideal methodology has yet to be defined. Several procedures have been described to induce hypertrophy of the FRL when needed. Each technique has its advantages and limitations, and among them portal vein embolization (PVE) is still considered the standard of care. About 20% of patients after PVEfail to undergo the scheduled hepatectomy, and newer secondary procedures, such as segment 4 embolization, ALPPS and HVE, have been proposed as salvage strategies. The aim of this review was to discuss the current modalities available and new perspectives in the optimization of FRL in patients undergoing major liver resection.N

Giant Pedunculated Hepatic Hemangioma: A Case Report and Literature Review

International audienceHepatic hemangioma is the most common benign hepatic tumor, and most of them are small in size and asymptomatic. Giant hepatic hemangiomas are uncommon, but pedunculated giant hemangiomas are even rarer and often difficult to diagnose because of their exophytic development. We report here on a 48-year-old man with a symptomatic pedunculated giant hepatic hemangioma and hepatic angiomatosis, mimicking a gastric gastrointestinal stromal tumor with liver metastases. The preoperative diagnosis was suspected on imaging including CT scan and MRI. The patient was successfully operated (left hepatic lobectomy), without any complication, and the pathological analysis confirmed the diagnosis. We reviewed the English literature, and to our knowledge, our case represents the largest case reported so far when compared with the 19 other informative cases
