AIM:To determine the clinical presentations, survival and prognostic factors of hepatocellular carcinoma (HCC) in Southern Thailand.METHODS:Retrospective analysis was performed on the 336 hepatocellular carcinoma patients treated at Songklanagarind hospital between 1 January 1991 and 31 January 1999.RESULTS:Of these 336 patients, 276 were males and 60 were females. The mean age was 54.4 years. The common symptoms and signs were abdominal pain and hepatomegaly. The most common presentation of tumor was a dominant mass with daughter nodules. Portal vein involvement was found in 50% of total. Extrahepatic metastasis was found in 13%, and the lung was the most common site. There were 65.4% with evidence of cirrhosis and half of them were in Child's class B. HBsAg was positive in 72.6%. Regarding a(c)Okuda's tumor staging, 15%, 61% and 24% were stage I, II and III, respectively. Overall median survival was 2.1 months (11.5 2.6 and 0.7 months for stage I, II and III respectively). Treatments of HCC improved patient survival (5.5 months vs 1.6 months for untreated patients). Most common causes of death were hepatic failure. Using multivariate analysis, the prognostic factors identified were tumor staging, alpha-fetoprotein level above 10000&mgr;gcenter dotL(-1), extrahepatic metastasis, portal vein thrombosis and treatment.CONCLUSION:HCC in Thailand is a fatal disease with poor outcome due to late presentation and high prevalence of liver cirrhosis. Early detection and proper management may improve outcome.

Ovarian cyst is a rare disease in infancy and childhood. Functional cysts are the most common benign ovarian tumor observed during childhood. Ultrasound examination in children with abdominal pain has improve diagnostic accuracy with an associated increase in the frequency of functional cysts (60% of the cases). Diagnosis of organic cysts is often made late. Germ cell tumors, often dermoid cysts, occur more frequently than in adults. Ultrasonography and laparoscopy are important diagnostic tools for ovarian cysts in children. Serum CEA, alpha-fetoprotein and beta HGC are routine tests for organic tumors. Laparoscopy is generally proposed for treatment except for small functional cysts with a transonic structure. Spontaneous involution is generally observed.

We present the first case in Bulgaria of cytologically verified undifferentiated (embryonal) sarcoma of the liver. A 10-year-old girl was admitted to the hospital with abdominal pain, extreme hepatomegaly, one-month fever, anemia and highly elevated erythrocyte sedimentation rate (95 mm). A large formation was found in the right liver lobe on ultrasound examination, which was polycystic on CT scan. Neither bone marrow abnormalities nor elevation of serum alpha-fetoprotein was found. In the scanty specimen obtained by fine-needle aspiration biopsy under ultrasound control a characteristic prevalence of polygonal cells within mesenchyme tissue was found. The cells had eccentric hyperchromic nuclei which were pushed to the periphery by large clusters of PAS-positive, diastase-resistant granules. Vimentin and alpha 1-antitrypsyn were expressed immunohistochemically. The cells are pathognomonic of undifferentiated (embryonal) sarcoma of the liver. After preoperative chemotherapy with ifosfamide, vincristine and actinomycin D (CEVAIE, CWS--96) resection of the tumor including IV, V, VI and VII liver segments was performed. A 30 x 30-cm soft gray-whitish tumor with fine capsule was found. The cytological diagnosis was histologically verified. The patient had a mechanical subileus episode after the 6th course of chemotherapy. One year after the surgery she is in good condition. The histogenesis of this rare tumor is discussed regarding its unique cytology, immunohistochemical constellation and ultrastructure. A literature review is presented. The case indicates that the unique cell appearance in embryonal sarcoma of the liver provides a correct diagnosis even in a scanty specimen.

A 6-year-old Malay boy presented with fever and abdominal pain for 2 months. Computerised tomography showed a nodular mass in the left lobe of the liver. There was also portal vein thrombosis on the left side. Serum alpha-fetoprotein was not elevated and Hepatitis B antigen was negative. Biopsy of the liver mass led to a histological diagnosis of fibrolamellar hepatocellular carcinoma. In view of extensive tumour involvement, he could not be operated on but was treated with chemotherapy. However, the tumour did not respond. While this is expected for fibrolamellar hepatocellular carcinoma, the possibility of the tumour having a component of ordinary hepatocellular carcinoma could not be excluded as the tumour was not resected. Fibrolamellar hepatocellular carcinoma is a rare histological subtype of hepatocellular carcinoma, associated with a better prognosis. It affects the younger age group and has no association with cirrhosis, hepatitis B virus infection or exposure to oral contraceptives, all of which are implicated in ordinary hepatocellular carcinoma. Serum alpha-fetoprotein level is usually within normal limits and other laboratory values are not contributory to the diagnosis. The diagnosis is usually suggested by radiographic studies viz. CT scan of the abdomen, which would show an irregular non-homogenous mass in the liver, and confirmed by histological examination. The most characteristic microscopical feature is fibrosis arranged in a lamellar fashion around polygonal and deeply eosinophilic neoplastic hepatocytes.

Here, we describe a 20-yr-old woman with COACH syndome (hypoplasia of Cerebellar vermis, Oligophrenia, congenital Ataxia, Coloboma, and Hepatic fibrosis) developing multiple liver lesions. Epigastric and right upper abdominal pain and lack of appetite led to clinical evaluation. Liver function tests showed an increase in transaminases and cholestatic parameters; alpha-fetoprotein was in the normal range. Ultrasound and magnetic resonance imaging examinations revealed multiple liver lesions. Histological examinations of ultrasonographically guided biopsies were consistent with regenerative hepatic nodules without features of malignant or dysplastic cells. The sizes of these tumors did not change over a period of 12 months. Our report presents the 10th case of COACH syndrome with a hitherto undescribed association with hepatic tumors.

Primary intrahepatic rhabdomyosarcoma is extremely rare in children. We describe a case of pleomorphic rhabdomyosarcoma originating from the liver in an eight-year-old boy presenting with abdominal pain, spiking fever and a rapidly growing abdominal mass for one week. Preoperative imaging studies revealed a large solid tumor in the right lobe of the liver without any tumor elsewhere in the body. Serological study was negative for HBsAg and positive for anti-HBs. Biochemical tests including serum glutamic-oxalacetic and glutamic-pyruvic transaminase, alkaline phosphatase, bilirubin and alpha-fetoprotein were all within normal limits. The tumor was removed by an extended right hepatectomy. Histological and immunohistochemical examination confirmed a pleomorphic rhabdomyosarcoma. The patient eventually succumbed to tumor recurrence with massive internal hemorrhage two months after resection of the tumor. This is the first report of primary pleomorphic rhabdomyosarcoma of the liver in children. Abdominal ultrasonography, computed tomography scan and angiography are valuable for preoperative planning but the imaging findings are non-specific. Pathological examination with immunohistochemical stains remains the most important method in arriving at the exact diagnosis. The poor prognosis and early death of most previously reported cases imply the need for investigation of a more effective treatment method of this uncommon tumor.

We report a successfully managed case of far-advanced hepatocellular carcinoma (HCC) by intraarterial infusion therapy. A 55-year-old man was admitted to our hospital with abdominal pain and subileus. Abdominal ultrasonography, computed tomography, and angiography revealed HCC with obstruction of the main portal vein due to tumor thrombus. Serum levels of alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II) were elevated. Neoadjuvant chemotherapy was tried with a course of low-dose cisplatin (CDDP) +5-fluorouracil (5-FU) intrahepatic arterial infusion through the indwelling catheter via the subcutaneous reservoir port. After 7 weeks of administration (total dose CDDP 370 mg/5-FU 18.5 mg), the main tumor size was effectively reduced. Serum levels of AFP and PIVKA-II decreased markedly. Adverse effects were tolerated. Following the chemoinfusion therapy, posterior segmentectomy and thrombectomy were performed. Reconstruction of the portal vein was not necessary because we removed the tumor thrombus without resecting the portal vein. The postoperative course was uneventful, and the patient has been doing well more than 2 years after surgery, with no evidence of recurrence or metastasis. Preoperative low-dose CDDP +5-FU intrahepatic arterial infusion therapy in combination with hepatic resection may be an effective treatment for advanced HCC with portal vein tumor thrombus.

We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; alpha-fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was reevaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

Hepatoblastoma is the most common primary liver tumour in children. Complete surgical removal is the treatment of choice for cure; however, in most cases the tumour is unresectable because of its extensive hepatic involvement. Nineteen pediatric cases (11 boys, 8 girls) with ages ranging from three months to 17 years were referred for management to our clinic from 1982 until 2000. All but three suffered from abdominal distention. The other frequent complaints were abdominal mass, anorexia, fatigue, abdominal pain and fever. Physical examination revealed enlarged liver in all patients. In addition to laboratory studies, they were pre-operatively examined by ultrasonography and, in recent cases, computed tomography was also used. Serum alpha-fetoprotein levels were found to be elevated in all patients. In thirteen cases, hepatic resections (10 lobectomies, 2 trisegmentectomies, 1 segmentectomy) were performed. In six children only liver biopsies could be done because of the huge tumour size. However, in three of them the tumours were excised at the second laparotomy, but only one patient survived. All of the patients - except two who were lost in the early postoperative period - received chemotherapy whether the tumour was excised or biopsied. In this series the mortality rate was found to be very high (91%) in the 1980s, and more reasonable (50%) in the 1990s, with an overall mortality rate of 73 per cent. This result might be explained with late referral and advanced stage at diagnosis. In addition, we speculate that a combination of improved chemotherapy and technical advances in anesthesia and hepatic resection caused the obvious differences in the survival rates between the two periods.

We report a 51-year-old man with a ruptured hepatocellular carcinoma (HCC). He was admitted to the hospital with abdominal pain and distension. Imaging studies revealed massive ascites, liver cirrhosis, and a 3-cm tumor at the inferior edge of the medial segment of the liver, with adhesions to the greater omentum. Abdominal paracentesis showed bloody ascites, and the patient was diagnosed with a ruptured HCC. OK-432, an immunomodulatory agent prepared from an attenuated strain of Streptococcus pyogenes, was injected (10 KE) into the peritoneal cavity four times within 1 week; the massive ascites disappeared, and the serum alpha-fetoprotein (AFP) level decreased to within the normal limits. Afterwards, he underwent a curative operation for HCC. His postoperative course was uneventful and he was discharged from the hospital on the twenty-second postoperative day. He had shown no evidence of recurrence or metastases at the time he died of hepatic failure related to alcohol abuse 9 months after the operation.
