BACKGROUND: Primary hepatic sarcomatous carcinoma (PHSC) is a rare malignancy composed of both carcinomatous (either hepatocellular or cholangiocellular) and sarcomatous components. The purpose of our study was to evaluate the imaging and clinical findings of PHSCs, improving the understanding and diagnosis of tumors. METHODS: We retrospectively reviewed the imaging and clinical findings of ten patients with pathologically proven PHSCs, including two cases of sarcomatous intrahepatic cholangiocarcinoma (S-ICC), seven cases of sarcomatous hepatocellular carcinoma (S-HCC) and one case of sarcomatous combined hepatocellular and cholangiocarcinoma (S-HCC-CC)...

Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) comprise the majority of primary liver cancers. Both HCC and ICC have characteristic imaging appearances on multiphase computed tomography (CT) and magnetic resonance imaging (MRI). Several locoregional therapies, including radiation therapy, are used to treat unresectable disease and residual or recurrent tumor. The tumor response following locoregional therapies has variable imaging manifestations. Focal liver reaction, the imaging changes of the liver following radiation treatment, should be recognized and not mistaken for tumor...

AIMS: Cholangiocarcinoma is a rare cancer arising from the biliary tree. Case series indicate that 25-40% of all borderline resectable primary tumours are potentially resectable. The Memorial Sloane Kettering System (MSKCC) stratifies patients for resectability by longitudinal and radial extension of the hilar tumour. The Bismuth-Corlette system describes the longitudinal extension of the tumour within the biliary duct system. We sought to validate and, if possible, augment these two scores within an independent validation cohort...

RATIONALE: Sarcomatous intrahepatic cholangiocarcinoma is a rare histological variant of cholangiocarcinoma (ICC). Previous medical literature has not mentioned the prevalence of this kind of disease, but a poorer prognosis than that of ordinary ICC was indicated. The diagnosis of the sarcomatous ICC is established on histopathological and immunohistochemical examinations. In this article, we present a new case of a patient with sarcomatous ICC who had no radiographic sign of intrahepatic tumor preoperatively...

BACKGROUND: Accurate differentiation between intrahepatic mass-forming cholangiocarcinoma (IMCC) and hepatocellular carcinoma (HCC) is needed because treatment and prognosis differ significantly. PURPOSE: To explore whether volumetric apparent diffusion coefficient (ADC) histogram analysis can provide additional value to dynamic enhanced MRI in differentiating IMCC from HCC. STUDY TYPE: Retrospective. POPULATION: In all, 131 patients with pathologically proven IMCC (n = 33) or HCC (n = 98)...

INTRODUCTION: Although curative resection is an outstanding prognostic factor of intrahepatic cholangiocarcinoma (ICC), certain segments remain unresectable. The standard therapy for initially unresectable ICC is uncertain. In this case report, we reported the feasibility of multimodal chemotherapy and curative resection. CASE: A 59-year-old Asian woman with back pain was referred to the hospital by her family physician regarding liver mass visible on ultrasonography...

Recent advances in dimensional imaging, surgical technique, and perioperative patient care have resulted in increased rates of complete resection with histopathologically negative margins and improved surgical outcomes in patients with extrahepatic cholangiocarcinoma. However, achieving cancer-free resection margins at ductal stumps in surgery for this disease remains challenging because of longitudinal extension, which is one of the hallmarks of extrahepatic cholangiocarcinoma. When the ductal resection margins are shown to be positive on examination of frozen sections, discrimination between carcinoma in situ and invasive carcinoma is clinically important because residual carcinoma in situ may lead to late local recurrence whereas residual invasive carcinoma is associated with early local recurrence...

Introduction: The emerging field of "radiomics" has considerable potential in disease diagnosis, pathologic grading, prognosis evaluation, and prediction of treatment response. We aimed to develop a novel radiomics nomogram based on radiomics features and clinical characteristics that could preoperatively predict early recurrence (ER) of intrahepatic cholangiocarcinoma (ICC) after partial hepatectomy. Methods: A predictive model was developed from a training cohort comprising 139 ICC patients diagnosed between January 2010 and June 2014...

Magnetic resonance cholangiopancreatography is a non-invasive imaging, highly performant in detecting and locating biliary stenosis and in predicting its malignancy. The combination of two and three-dimensional MRI sequences is recommended to assess a biliary obstacle. Cholangiopathies are the main differential diagnosis of cholangiocarcinomas. In addition to bile duct abnormalities beyond the stenosis, the predictive signs of malignancy are: asymmetric irregular luminal narrowing (longer than 3mm and thicker than 13mm), abrupt discontinuation of stenosis, and enhancement superior to that of the adjacent hepatic parenchyma during arterial and portal acquisitions...

PURPOSE: To distinguish hepatocellular carcinoma (HCC) from other types of hepatic lesions with the adaptive multi-exponential IVIM model. METHODS: 94 hepatic focal lesions, including 38 HCC, 16 metastasis, 12 focal nodular hyperplasia, 13 cholangiocarcinoma, and 15 hemangioma, were examined in this study. Diffusion-weighted images were acquired with 13 b values (b = 0, 3, …, 500 s/mm2 ) to measure the adaptive multi-exponential IVIM parameters, namely, pure diffusion coefficient (D), diffusion fraction (fd ), pseudo-diffusion coefficient (Di *) and perfusion-related diffusion fraction (fi ) of the ith perfusion component...

The incidence of combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CC) in a single patient accounts for only 0.4 to 14% of all primary liver cancer. However, the prognosis of its intrahepatic cholangiocarcinoma (ICC) component is poor. We experienced a unique case of a sequentially developed cHCC-CC with adrenal metastasis as the primary presentation and a hidden primary hepatocellular carcinoma. A 65-year-old female with a history of jaundice and abdominal discomfort was diagnosed with S4 ICC measuring 5 cm in diameter, and characterized histologically as papillary adenocarcinoma with intraductal growth, but without any evidence of malignant hepatocyte...

Primary hepatocellular carcinoma (PHC) includes hepatocellular carcinoma, intrahepatic cholangiocarcinoma and other pathological types and is characterized by rapid progression. Most of the clinical diagnoses are made at late stage or when distant metastasis occurs, increasing the difficulty of treatment and resulting in a poor prognosis. Therefore, the early diagnosis of PHC plays an important role in timely treatment and the improvement of prognosis. The gold standard for the diagnosis of primary liver cancer is liver biopsy, but it has limitations as an invasive examination...

Cholangiocarcinoma is a most lethal malignancy frequently resistant to chemotherapy. Herpes simplex virus thymidine kinase/Ganciclovir (HSV-TK/GCV) suicide gene therapy is a promising approach to treat different cancers, including cholangiocarcinoma. However drawbacks including low therapeutic gene expression and lack of precise targeted gene delivery limit the wide clinical utilization of the suicide gene therapy. We attempted to overcome these obstacles. We established the "proof-of-principle" of this concept via serial in-vitro experiments using human cholangiocarcinoma cells and then validated the new interventional oncology technique in vivo using mice harboring the same patient derived cholangiocarcinomas...

Concurrent laryngeal squamous cell carcinoma and intrahepatic cholangiocarcinoma is rare and no prior report has been found through a PubMed search. Here we report such a case of a 51-year old obese male presenting with hoarseness and trouble swallowing for 2 to 3 months. Imaging findings of computer tomography (CT) and magnetic resonance imaging (MRI) with and without contrast were suspicious for a T3N2 supraglottic laryngeal cancer. Laryngeal biopsy showed a well differentiated squamous cell carcinoma (SCC)...

BACKGROUND: Growing evidence has suggested that intrahepatic cholangiocarcinoma (iCCA) can be classified into small- and large-duct types. The present study aimed to elucidate how large-duct iCCA is similar and dissimilar to perihilar cholangiocarcinoma (pCCA). METHODS: The study cohort consisted of iCCA (n = 58) and pCCA (n = 44). After iCCA tumors were separated into small- (n = 36) and large-duct (n = 22) types based on our histologic criteria, genetic statuses of the three types of neoplasms were compared...

Rapid advances in imaging technology have improved the detection, characterization and staging of colorectal liver metastases, hepatocellular carcinoma and cholangiocarcinoma. A variety of imaging modalities are available and play a pivotal role in the work-up of patients, particularly as imaging findings determine resectability. Surgery often represents the only measure that can render long-term survival possible. Imaging is also indispensable for the assessment of responses to neoadjuvant treatment and for the detection of recurrence...

INTRODUCTION: Cholangiocarcinoma (CCA) is the primary tumor found in the bile duct and is associated with a high incidence of lymph node (LN) metastases and poor outcomes. The presence of metastatic lymph nodes, when shown by imaging, can influence patient treatment and prognosis. DWI is a promising, non-invasive imaging technique for differentiating between benign and malignant LNs. Many studies have shown that LN metastases have a lower apparent diffusion coefficient (ADC) value when compared to benign nodes...

BACKGROUND: Patients with resectable perihilar cholangiocarcinoma (PHC) on imaging have a substantial risk of metastatic or locally advanced disease, incomplete (R1) resection, and 90-day mortality. Our aim was to develop a preoperative prognostic model to predict surgical success, defined as a complete (R0) resection without 90-day mortality, in patients with resectable PHC on imaging. STUDY DESIGN: Patients with PHC who underwent exploratory laparotomy in three tertiary referral centers were identified...
