Review
This report explores the available curative molecules directed against hepatocellular carcinoma (HCC). Limited efficiency as well as other drawbacks of existing molecules led to the search for promising potential alternatives. Understanding of the cell signaling mechanisms propelling carcinogenesis and driven by cell proliferation, invasion, and angiogenesis can offer valuable information for the investigation of efficient treatment strategies. The complexity of the mechanisms behind carcinogenesis inspires researchers to explore the ability of various biomolecules to target specific pathways. Natural components occurring mainly in food and medicinal plants, are considered an essential resource for discovering new and promising therapeutic molecules. Novel biomolecules normally have an advantage in terms of biosafety. They are also widely diverse and often possess potent antioxidant, anti-inflammatory, and anti-cancer properties. Based on quantitative structure-activity relationship studies, biomolecules can be used as templates for chemical modifications that improve efficiency, safety, and bioavailability. In this review, we focus on anti-HCC biomolecules that have their molecular targets partially or completely characterized as well as having anti-cancer molecular mechanisms that are fairly described.

Review
Fibrolamellar hepatocellular carcinoma (FLHCC) is a primary liver tumor. It is a pathologically distinct variety of hepatocellular carcinoma (HCC). The term 'fibrolamellar' is derived from the presence of thick fibrous collagen bands surrounding the tumor cells. It is a relatively rare tumor of unknown biology. It has a distinctive predilection for adolescents and young adults with no underlying liver disease or cirrhosis. FLHCC patients have higher incidence of lymph node involvement than conventional HCC patients probably owing to larger median tumor size at presentation. Most cases present at an advanced stage at the time of initial diagnosis, however, curative intent treatment options can still be offered to up to 70% of patients. Surgery (resection/liver transplantation) is the current mainstay of treatment and remains the only potentially curative option. As recurrences are common, alternative therapies are under investigation. FLHCCs have traditionally been considered less chemo-responsive than their conventional HCC counterparts, but in advanced cases multimodality treatments can be effective. Compared to stage-matched non-cirrhotic patients with HCC, patients with FLHCC do not have a favourable prognosis and do not respond differently to treatment. The survival advantage observed in FLHCC over conventional HCC is most likely due to younger age at presentation and absence of cirrhosis.

Review
Assessing the balance between survival and recurrence after transplantation for secondary liver tumours should be based on the type of cancer in question. For neuroendocrine liver metastases, high recurrence rates are clearly related to reduced long-term survival. For colorectal liver metastases, experience to date indicates that pulmonary recurrence alone has a modest impact on survival outcomes. Further studies focusing on this group of patients will be important for the development of this field of transplant oncology. Liver transplantation for secondary liver tumours should be implemented in accordance with stringent transplant criteria and preferably in the context of prospective trials. Expansion of the donor pool by utilising extended criteria donors and partial liver transplantation could be considered for this indication.

Review
Purpose: The fifth most common cancer of the gastrointestinal system is liver cancer. It is also one of the most common cancers worldwide. The available treatment options include surgery, percutaneous ablation, and liver transplantation. Some of the latest modalities for the management of hepatocellular carcinoma (HCC) are radiofrequency ablation, trans-arterial chemoembolization, radioembolization and systemic targeted agents like sorafenib. The process of choice of a particular treatment modality in HCC depends on the tumor stage, patient performance status and liver function reserve. In the recent past with progress in research, the short-term survival of HCC has improved but recurrent disease remains a fundamental problem as the pathogenesis of HCC is a multistep and complex process. The present review is focused on recent advances in the management of HCC. This review will also provide an insight on the upcoming latest modalities including the emerging role of hepatoma-derived growth factor (HDGF) overexpression in liver fibrosis and carcinogenesis.

Review
OBJECTIVES
To review liver physiology, the disease process, diagnostic tests, and current treatment options for primary and metastatic liver cancer.
DATA SOURCES
Research studies, review articles, and textbooks relating to liver cancer.
CONCLUSIONS
Surgical resection offers the best available treatment modality, but only a small percentage of patients are eligible. However, combined treatment of radiation therapy and chemotherapy (systemic and intra-arterial), as well as chemoembolization, cryosurgery, and transplantation, offers hope of palliation, conversion of unresectable to resectable disease, and prolonged survival.
IMPLICATIONS FOR NURSING PRACTICE
Understanding and knowledge of the disease process and treatment modalities for primary and metastatic liver cancer will assist the oncology nurse in educating patients and families during their diagnostic and treatment phases.

Review
Advanced hepatocellular carcinoma (HCC) has presented a therapeutic challenge. Despite its heterogeneity, which is partially related to its various etiologies, it frequently arises in a background of chronic inflammation, which makes it a potentially excellent candidate for immunotherapeutic approaches. There is evidence of antitumor immunity in HCC as manifested by the cell infiltrate and its association with prognosis, the presence of tumor-associated antigens, and the reports of immune-mediated spontaneous regressions. However, both the liver itself and the tumor environment possess a diverse armamentarium of mechanisms that suppress antitumor immunity. Here, we describe the rationale for immunotherapy in HCC and discuss the emerging clinical data from various immunotherapeutic approaches including checkpoint inhibition, cell therapy, oncolytic viral therapy, and various combinatorial approaches. We also highlight the potential for various modalities to be adapted across different stages of the disease.

Review
Primary liver cancer is the fifth most common cancer overall and the second most common cause of cancer mortality worldwide. Hepatocellular carcinoma accounts for up to 90% of all primary hepatic malignancies and represents a major international health problem. It is a complex and heterogeneous malignancy, frequently occurs in the setting of a chronically diseased organ, and has multiple confounding factors. Liver transplant for hepatocellular carcinoma has been established as a standard treatment in selected patients. Liver resection and locoregional therapies could be other options for treatment. Pathologic evaluation of hepatocellular carcinoma is a complicated process that includes tumor grading and evaluation of microvascular invasion. Although macrovascular invasion can be detected with imaging techniques, microvascular invasion is diagnosed pathologically. Pathologic evaluation provides additional information about the tumor biology, using immunohistochemical and molecular methods to predict patient outcomes. Hepatocellular carcinoma requires a multidisciplinary approach to determine the most appropriate treatment, as well as requires accurate timing of various treatments for optimal outcomes.

Review
Hepatic angiomyolipoma is a rare, benign, hepatic mesenchymal neoplasm found in both males and females, and most commonly in adult females. Angiomyolipoma occurs most commonly in the kidneys. The liver represents the second most frequent site of involvement. Hepatic angiomyolipomas are composed of varying amounts of smooth muscle cells, adipose tissue, and vessels. The smooth muscle cell component is the most specific to the diagnosis. The smooth muscle cells can have varying morphologies and are positive for homatropine methylbromide-45 but are negative for hepatocyte paraffin 1 and S100 protein. The definitive diagnostic study remains the histologic examination of the surgically resected lesion coupled with immunohistochemical stains. The differential diagnosis includes hepatocellular carcinoma, hepatic adenoma, leiomyoma, hepatoblastoma, melanoma, and gastrointestinal stromal tumor. The immunohistochemical staining pattern differentiates this lesion from other malignant and benign liver lesions. If the diagnosis of hepatic angiomyolipoma has been made, it can be followed conservatively or surgically resected.

Review
Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy and a leading cause of cancer related death worldwide. Current guidelines for the noninvasive diagnosis of HCC are provided by the European Association for the Study of the Liver (EASL), the American Association for the Study of Liver Diseases (AASLD) which endorsed the Liver Imaging Reporting and Data System (LI-RADS) algorithm, the Korean Liver Cancer Association-National Cancer Center (KLCA-NCC), and the Asian-Pacific Association for the Study of the Liver (APASL). These allow the diagnosis of HCC in high-risk patients in the presence of typical imaging features on contrast-enhanced CT, MRI, or contrast-enhanced ultrasound. Size, non-rim arterial phase hyperenhancement, non-peripheral washout, enhancing capsule, and growth are major imaging features and they should be combined for the diagnosis of HCC. This article provides concise and relevant practice recommendations aimed at general radiologist audience, summarizing the best practice and informing on the essential imaging criteria for the diagnosis of HCC, while also discussing the high-risk population criteria, imaging modalities, and imaging features according to the current guidelines. KEY POINTS: • Noninvasive diagnosis of hepatocellular carcinoma (HCC) can be provided only in patients at high risk. • Contrast-enhanced CT or MRI are the first-line imaging exams for the diagnosis of HCC. • Major imaging features should be combined to provide the diagnosis of definitive HCC.
