Massive hepatocellular carcinoma has a local tumor recurrence rate of 30% to 40%. A definitive diagnosis of neoplasia can always be achieved on cytology of liver aspirates.

Intraoperative hemorrhage has been reported in 25% of patients undergoing liver lobectomy, with major hemorrhage recorded as being secondary to trauma to the caudal vena cava, occurring in over 7% of cases.2 Before surgery, coagulation profiles, blood type, and crossmatch as appropriate should be evaluated. 5. The study of liver regeneration was largely triggered by Ecks seminal paper on complete PCS (Eck fistula) in dogs in 1877 [] which led to the belief that the livers homeostasis was not dependent upon portal blood perfusion.However, in 1893 this was contested by Hahn et al.

Figure 2. Our data suggest that the liver can be divided into two sections, three divisions, seven lobes and two to four sub-lobes. 26. 1989, Farrar et al. Cholangiocytes and hepatocytes have a shared hepatic progenitor cell; therefore, some neoplastic processes can have characteristics that overlap between hepatocytes and cholangiocytes, such as cholangiocarcinomas.3 Cholangiocellular tumors are reported less frequently than hepatocellular carcinoma, with cholangiocellular carcinomas more common than cholangiocellular adenomas.3,10, Similar to hepatocellular carcinoma, cholangiocellular carcinoma has been divided into massive, nodular, and diffuse morphologic descriptions, with the left lateral lobe most commonly affected in the massive group of tumors; this contributes to the difficulty in differentiating cholangiocellular tumors from hepatocellular tumors grossly and makes histologic examination critical for a definitive diagnosis.1,12 The metastatic rate for intrahepatic bile duct carcinomas is 86%, with the most common sites including lymph nodes, lungs, and peritoneum, making this disease process overall more malignant than hepatocellular carcinoma.12, Primary hepatic neuroendocrine carcinomas are rare and likely arise from existing neuroendocrine cells in the biliary epithelium.3 Primary hepatic neuroendocrine carcinomas cause nodular or diffuse lesions throughout the liver, with lymph node metastasis, peritoneal carcinomatosis, and intrahepatic metastasis occurring in most cases.3,12,13 Other primary malignant tumors of the liver include several types of sarcoma (e.g., fibrosarcoma, hemangiosarcoma, histiocytic sarcoma), lymphoma, and malignant peripheral nerve sheath tumor.1,10, Surgical intervention is indicated as the treatment of choice for massive, solitary liver tumors.5 Nodular and diffuse disease processes are intrinsically considered to be nonresectable tumors, as multiple liver lobes are commonly involved.14,15 While further diagnostics, as discussed below, are indicated before surgical intervention, it has been proposed that exploratory surgery should also be performed when a large intra-abdominal mass is present, even without a definitive diagnosis, for further staging purposes as well as to further determine the ability to resect the mass.2, The left division is more mobile than the other divisions and has a deep fissure from the remaining liver, making left-division liver lobectomies generally less technically challenging than right- or central-division lobectomies.16 Hilar tumors generally need extensive resection, increasing the surgical difficulty compared with more peripheral lesions; for example, complete resection of hilar tumors using surgical stapling devices alone is often challenging.8,16, Compared with hepatocellular carcinomas, hepatocellular adenomas are presumed to have a better prognosis, while biliary carcinomas, sarcomas, and neuroendocrine carcinomas are suspected to have a worse prognosis; however, there is little to no primary literature to support these assumptions.6 The prognosis is regarded as poor for dogs with nodular and diffuse forms of hepatocellular carcinoma, as surgery is not feasible in most of these cases.15 In dogs undergoing surgery for massive hepatocellular carcinoma, negative prognostic factors include high serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, increased alkaline phosphatase (ALP):AST and ALT:AST ratios, and the presence of right-sided tumors, although this last indicator was suspected to be secondary to a high intraoperative mortality rate associated with right-sided tumors.2 Additionally, nontachypneic dogs and dogs with a history of lethargy have been associated with a higher risk of death during liver lobectomy to address a liver tumor than dogs without these characteristics.6, The reported mean age at presentation for hepatocellular carcinoma is 11 to 13 years.1,10 In one study, dogs with bile duct carcinomas, sarcomas, and neuroendocrine carcinomas had a mean age at presentation of 10, 11, and 8 years, respectively; it is important to note that the bile duct carcinoma group consisted of 22 intrahepatic cholangiocellular carcinomas and 2 extrahepatic masses.1 Males, Shih Tzus, and Yorkshire terriers have been reported to be overrepresented in cases of hepatocellular carcinoma; however, these reports vary between studies.1,10, Dogs often have clinical signs that could be attributed to a liver mass.6 In some dogs, however, hepatic masses are found incidentally.16 Historical findings can include anorexia, hyporexia, lethargy, weakness, vomiting, weight loss, diarrhea, polyuria, and polydipsia.1,6 Clinical signs can include hepatomegaly, palpable abdominal mass, abdominal distention, abdominal effusion, abdominal pain, icterus, and increased respiratory rate or effort.1,6,16 Ascites, diarrhea, jaundice, and weight loss may be more common in dogs with neuroendocrine carcinoma, while hepatomegaly is not typically associated with neuroendocrine carcinoma.1 Neurologic clinical signs are less frequently reported but may include ataxia, seizures, and other signs consistent with a myelopathy; neurologic signs may be caused by hepatoencephalopathy, metastatic disease, or concurrent primary neurologic disease.1,6, Dogs with primary hepatic tumors can present with multiple disease processes, highlighting the importance of a thorough physical examination.2 Hemoabdomen is uncommonly noted at the time of presentation but can be identified in dogs with various types of hepatic tumors.6, Baseline clinicopathologic diagnostic tests include complete blood count, serum chemistry profile, pre- and post-prandial bile acid assays, coagulation profile, blood typing, and urinalysis.2,6 Thrombocytosis, anemia, and increased serum liver enzyme activities are frequently noted in dogs with massive hepatocellular carcinoma.2 Pre- and post-prandial bile acid levels are often increased, which may be suggestive of some liver dysfunction.2,6 Coagulation profiles are often normal, although prolonged prothrombin time and partial thromboplastin time, as well as hyperfibrinogenemia, can be noted.6,16 Urinalysis most commonly reveals hypersthenuria and aciduria, though many variations are noted.6, Cytologic samples can be obtained via ultrasound-guided liver aspiration.2 Diagnosis of some neoplasias, such as hepatocellular carcinoma, can be achieved by cytology; however, making a diagnosis can be challenging if cytologic morphology is relatively normal.17, Imaging modalities include abdominal radiography, ultrasonography, and computed tomography (CT) (Figure 3), as well as thoracic radiography to assess for pulmonary metastasis.2 Both CT and ultrasonography can be used to localize solitary hepatic masses;5 however, they should not be relied on alone to make a specific diagnosis. 27.
