Preoperative prediction of post hepatectomy liver failure after surgery for hepatocellular carcinoma on CT-scan by machine learning and radiomics analyses.

Introduction: No instruments are available to predict preoperatively the risk of posthepatectomy liver failure (PHLF) in HCC patients. The aim was to predict the occurrence of PHLF preoperatively by radiomics and clinical data through machine-learning algorithms.

Materials And Methods: Clinical data and 3-phases CT scans were retrospectively collected among 13 Italian centres between 2008 and 2022.

Liver transplant for hepatocellular carcinoma in metabolic dysfunction-associated steatotic liver disease versus other etiologies: A meta-analysis.

Background & Aims: Liver transplantation for hepatocellular carcinoma (HCC) in metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly being diagnosed and predicted to rise further. We compared outcomes of transplantation for MASLD-related HCC versus other etiologies (OE).

Methods: Databases were searched to identify studies comparing outcomes after transplantation MASLD-related HCC with OE-related HCC.

Unveiling the prognostic role of blood inflammatory indexes in a retrospective cohort of patients undergoing liver resection for intrahepatic cholangiocarcinoma.

Background: Systemic inflammation is relevant in intrahepatic cholangiocarcinoma (iCCA), but controversial results exist on the prognostic role of inflammatory indexes and their correlation with tumor microenvironment. The authors aimed to explore the biological and prognostic values of these indexes.

Materials And Methods: A retrospective cohort study involving iCCA patients who underwent hepatic resection between 2010 and 2021 was conducted.

Preoperative detection of hepatocellular carcinoma's microvascular invasion on CT-scan by machine learning and radiomics: A preliminary analysis.

Introduction: Microvascular invasion (MVI) is the main risk factor for overall mortality and recurrence after surgery for hepatocellular carcinoma (HCC).The aim was to train machine-learning models to predict MVI on preoperative CT scan.

Methods: 3-phases CT scans were retrospectively collected among 4 Italian centers.

ICG-Enhanced Compression Anatomical Segment 7 Segmentectomy in Laparoscopic and Robotic Approach.

Background: Minimally invasive anatomical resection (AR) for posterosuperior lesions is technically challenging. The Glissonean approach or puncture technique is generally selected. The tumor-feeding portal pedicle compression AR (C-AR) is an established procedure in open surgery.

Clinical outcomes after transplantation of domino grafts or standard deceased donor livers: a systematic review and meta-analysis.

Background And Aim: Domino liver transplantation (DLT) utilizes otherwise discarded livers as donor grafts for another recipients. It is unclear whether DLT has less favorable outcomes compared to deceased donor liver transplantation (DDLT). We aimed to assess the outcomes of DLT compared to DDLT.

Filamin A is involved in human intrahepatic cholangiocarcinoma aggressiveness and progression.

Background & Aims: Intrahepatic cholangiocarcinoma (iCCA) is a primary liver tumour, characterized by poor prognosis and lack of effective therapy. The cytoskeleton protein Filamin A (FLNA) is involved in cancer progression and metastasis, including primary liver cancer. FLNA is cleaved by calpain, producing a 90 kDa fragment (FLNA ) that can translocate to the nucleus and inhibit gene transcription.

How Much Is Enough? A Surgical Perspective on Imaging Modalities to Estimate Function and Volume of the Future Liver Remnant before Hepatic Resection.

Liver resection is the first curative option for most hepatic primary and secondary malignancies. However, post-hepatectomy liver failure (PHLF) still represents a non-negligible postoperative complication, embodying the most frequent cause of hepatic-related mortality. In the absence of a specific treatment, the most effective way to deal with PHLF is its prevention through a careful preoperative assessment of future liver remnant (FLR) volume and function.

Hepatectomy versus Chemotherapy for Resectable Colorectal Liver Metastases in Progression after Perioperative Chemotherapy: Expanding the Boundaries of the Curative Intent.

Disease progression (PD) at neoadjuvant chemotherapy for patients with colorectal liver metastases (CLMs) is considered a contraindication to hepatic resection. Our aim was to estimate the overall survival (OS) in patients undergoing surgery compared with those treated exclusively with chemotherapy in cases of PD. Patients from a single centre with PD were analyzed and subdivided into two groups: hepatectomy (HEP) versus chemotherapy (CHT).

Upfront Surgery versus Neoadjuvant Perioperative Chemotherapy for Resectable Colorectal Liver Metastases: A Machine-Learning Decision Tree to Identify the Best Potential Candidates under a Parenchyma-Sparing Policy.

Addressing patients to neoadjuvant systemic chemotherapy followed by surgery rather than surgical resection upfront is controversial in the case of resectable colorectal -liver metastases (CLM). The aim of this study was to develop a machine-learning model to identify the best potential candidates for upfront surgery (UPS) versus neoadjuvant perioperative chemotherapy followed by surgery (NEOS). Patients at first liver resection for CLM were consecutively enrolled and collected into two groups, regardless of whether they had UPS or NEOS.

Laparoscopic Ultrasound-Guided R1 Vascular Liver Resection for Colorectal Liver Metastases at Caval Confluence.

Background: Patients with tumors involving the hepatic vein (HV) at the caval confluence (CC) usually receive major hepatectomies or HV grafting. For colorectal liver metastases (CLM), tumor-vessel detachment (R1vasc) has proven to be oncologically adequate. However, parenchyma-sparing R1vasc surgery has usually been confined to the open approach.

Surgical Strategies for Recurrent Hepatocellular Carcinoma after Resection: A Review of Current Evidence.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, and both liver resection and liver transplantation are considered potentially curative options. However, high recurrence rates affect the prognosis depending both on the primary HCC pathology characteristics or on the type and time of the relapse. While great attention has been usually posted on treatment algorithms for the first HCC, treatment algorithms for recurrent HCC (rHCC) are lacking.

Multidisciplinary Tumor Board in the Management of Patients with Colorectal Liver Metastases: A Single-Center Review of 847 Patients.

There is still debate over how reviewing oncological histories and addressing appropriate therapies in multidisciplinary team (MDT) discussions may affect patients’ overall survival (OS). The aim of this study was to describe MDT outcomes for a single cancer center’s patients affected by colorectal liver metastases (CRLMs). From 2010 to 2020, a total of 847 patients with CRLMs were discussed at our weekly MDT meeting.

Internal mammary lymph node siliconoma in absence of prosthesis rupture: a case series that raises concern for potential risk of overdiagnosis.

Background: Silicon migration after rupture is an adverse event of breast implant, whose risk increases with the aging of prosthesis. The exact prevalence of this complication remains unclear and reported data are inconsistent. In addition, microscopic diffusion of silicone gel through intact implant, known as gel bleeding, might verify thus complicating diagnosis.

Impact of RAS mutations on the immune infiltrate of colorectal liver metastases: A preliminary study.

Kirsten rat sarcoma viral oncogene homolog KRAS proto-oncogene is the most common altered gene in colorectal cancer (CRC). Determining its mutational status, which is associated with worse prognosis and resistance to anti-epidermal growth factor receptor (EGFR) inhibitors, is essential for managing patients with CRC and colon liver metastases (CLM). Emerging studies highlighted the relationship of KRAS-mutated cancers and tumor microenvironment components, mainly with T cells.

Mucinous breast cancer: A narrative review of the literature and a retrospective tertiary single-centre analysis.

Mucinous carcinoma (MC) is a rare breast cancer characterized by the presence of large extracellular mucin amount. Two main subtypes can be distinguished: pure (PMC) and mixed (MMC). We conducted a retrospective MC analysis in our prospective maintained database, calculating disease-free survival (DFS) and 5-year overall survival (OS).
