Intrahepatic splenosis is an uncommon condition that can present a significant diagnostic challenge, often masquerading as more sinister hepatic lesions. We report a perplexing case of a 56-year-old female with a history of splenectomy who presented with liver masses initially suspected to be hepatocellular carcinoma (HCC). Despite advanced imaging techniques, including ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI), the lesions convincingly mimicked HCC.

Article Synopsis
  • Severe aortic stenosis (AS) can lead to acquired von Willebrand syndrome by breaking down important blood clotting factors, requiring accurate diagnosis methods to identify the condition.* -
  • The study evaluated the effectiveness of the VWF Ristocetin co-factor activity to antigen levels (VWF:RCo/VWF:Ag) ratio as a diagnostic tool for AS-induced von Willebrand syndrome using data from 382 AS patients and controls.* -
  • Results showed a VWF:RCo/VWF:Ag ratio of <0.7 is specific for detecting loss of important blood clotting multimers in patients with AS, but it has low sensitivity, indicating it might miss some cases.*

Background: Interactions between adipocyte and breast cancer (BC) cells have yet to be fully elucidated. Here we investigated the prognostic impact of marginal adipose tissue invasion in both luminal breast cancer (HR+/HER2-) and triple-negative breast cancer (TNBC) (HR-/HER2-).

Methods: A total of 735 patients with early-stage invasive BC (1999-2014) were retrospectively registered.

Background: Microvascular invasion (MVI) is recognized as a risk factor for early recurrence of hepatocellular carcinoma (HCC) within the Milan criteria after curative treatment.

Methods: One hundred eleven consecutive patients with HCC within the Milan criteria who underwent hepatic resection were retrospectively reviewed. Independent preoperative predictors of MVI were identified, and a scoring system was developed using significant predictors.

Background/aims: Some patients experience very late recurrence of HCC more than 5 years after initial therapy. We aimed to clarify the predictive factors for very late recurrence of HCC in such cases.

Methods: Among 807 HCC patients undergoing surgical resection or ablative therapy with curative intent, the patients who survived for 5 years without any recurrence were reviewed.

Background And Aim: The effects of achieving sustained virological response (SVR) on recurrence and survival after curative treatment in patients with hepatitis virus C (HCV)-related hepatocellular carcinoma (HCC) is unclear. This study examined the influence of SVR achievement by interferon therapy before HCC occurrence on recurrence and survival.

Methods: This retrospective study included 518 patients who underwent surgical microwave ablation for initial HCV-related HCC between January 2001 and December 2015.

Objective Sorafenib is a standard therapy for advanced hepatocellular carcinoma (HCC), whereas radiotherapy is effective for local control of extrahepatic spread (EHS) or macrovascular invasion (MVI). This study investigated the safety and efficacy of this combined therapy to treat advanced HCC. Methods This retrospective study reviewed 62 patients with advanced-stage HCC with EHS or MVI who received sorafenib therapy, excluding the patients with only lung metastases.

Background: Indications and efficacy of surgical treatment for liver metastases from gastric cancer (LMGCs) remain controversial. This retrospective study was designed to clarify the benefits of surgical treatment and identify prognostic factors.

Methods: Between December 1997 and December 2015, 34 consecutive patients underwent hepatic resection and surgical microwave ablation for synchronous or metachronous LMGCs at our institution.

The prognostic implications of the expression patterns of three tumor markers, alpha-fetoprotein (AFP), the Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3) and des-γ-carboxy prothrombin (DCP), have been evaluated in patients with hepatocellular carcinoma (HCC). From January 1994 to December 2014, 1182 consecutive patients underwent hepatic resection and surgical microwave ablation for HCC at our institution. This study analyzed 475 patients within the Milan criteria and Child-Pugh class A.

Purpose: To establish the efficacy and safety of simultaneous microwave coagulo-necrotic therapy (MCN) and laparoscopic splenectomy (Lap-Sp) for the treatment of hepatocellular carcinoma (HCC) with cirrhotic hypersplenism.

Methods: Seventeen patients with HCC and cirrhotic hypersplenism underwent simultaneous MCN and Lap-Sp at our institution between January, 2010 and July, 2015. Eight and nine patients had Child-Pugh class A and B liver cirrhosis, respectively.

Background: Five or more colorectal liver metastases (CRLM) are considered marginally resectable and cannot be treated solely by hepatic resection (Hr). This study investigated the long-term effectiveness of surgical treatment using microwave coagulo-necrotic therapy (MCN) and/or Hr for marginally resectable or unresectable multiple CRLM.

Methods: This study retrospectively analyzed 82 consecutive CRLM patients with ≥5 CRLM who underwent MCN, Hr, or both, at our institution from 1994 to 2012.

Background: Because the recurrence rate of hepatocellular carcinoma (HCC) is high, even after curative treatments such as hepatic resection and microwave ablation, chemopreventive agents that can effectively suppress HCC recurrence are required. Cyclooxygenase-2 (Cox-2) was recently found to be overexpressed in HCC. Therefore, Cox-2 inhibitors may offer a chemopreventive therapy for HCC.

Background: Whether radiologically detected progressive disease (PD) is an accurate metric for discontinuing sorafenib treatment in patients with hepatocellular carcinoma (HCC) is unclear. We investigated the efficacy of sorafenib treatment after radiologic confirmation of PD in patients with advanced HCC.

Methods: We retrospectively analyzed HCC patients treated with sorafenib at Kyushu Medical Center.

Background: Sorafenib therapy improves survival in unresectable hepatocellular carcinoma (HCC) patients without an objective response. The present study investigated whether the initial imaging response might be a prognostic indicator after administration of sorafenib therapy in HCC patients.

Patients And Methods: This retrospective study reviewed unresectable HCC patients undergoing sorafenib therapy.

Sorafenib is an effective treatment for unresectable hepatocellular carcinoma (HCC) characterized by disease stabilization. However, the response rates are very low (<9%percnt;), and a complete response is rarely achieved. We report an extremely rare case of a HCC patient with multiple lung metastases treated with sorafenib who achieved a complete response for a long period.

Carcinosarcoma is a rare neoplasm with epithelial and mesenchymal components. We herein report the case of a 68-year-old male with a carcinosarcoma of the gallbladder. Preoperative examinations revealed the gallbladder cancer infiltrating the liver with a multinodular mass with a portal vein tumor thrombus through the right anterior branch of the portal vein.
