Malignant transformation of mesenchymal hamartoma of the liver: case report and review of the literature

Ramanujam TM, Ramesh JC, Goh DW, Wong KT, Ariffin WA, Kumar G, et al.

J Pediatr Surg, 1999 Nov;34(11):1684-6.
PMID: 10591570

Here the first case in the literature of both mesenchymal hamartoma and malignant mesenchymoma occurring in a 6-year-old male child, at different times and at different sites in the liver, and also the possible malignant transformation of a mesenchymal hamartoma is reported. The tumor developed from a lesion in the right lobe that was overlooked initially during a left lateral segmentectomy at 18 months of age for a mesenchymal hamartoma. Malignant mesenchymoma is a rare and aggressive tumor. The origin of this tumor is not well understood. There has been no direct support to the hypothesis that malignant mesenchymoma may be the malignant counterpart of mesenchymal hamartoma. The authors provide clinical and histopathologic evidence in our case that suggests the possibility of malignant mesenchymoma arising from a mesenchymal hamartoma. This case emphasizes the need for complete removal of mesenchymal hamartoma and the need for long-term follow-up to detect multifocal lesion or malignant transformation.

PMID: 8102564

The effects of long-term administration of tocotrienol on hepatocarcinogenesis in rats induced by diethylnitrosamine (DEN) and 2-acetylaminofluorene (AAF) were investigated by determining the activities of gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), glutathione S-transferases (GSTs), and glutathione (GSH) levels in blood and liver. Twenty-eight male 7- to 8-wk-old Rattus norwegicus rats, weighing 120-160 g, were used in this study. The rats were divided into four treatment groups: a control group on a basal diet, a group fed a basal diet supplemented with tocotrienol (30 mg/kg food), a group treated with DEN/AAF, and a group treated with DEN/AAF and fed a diet supplemented with tocotrienol (30 mg/kg food). Blood was collected monthly, and GGT, ALP, and GSH levels were determined. The rats were killed after 9 mo, and the livers were examined morphologically. Grayish white nodules (2/liver) were found in all the DEN/AAF-treated rats (n = 10), but only one of the rats treated with DEN/AAF and supplemented with tocotrienol (n = 6) had liver nodules. A significant increase in the level of blood and liver GSH, ALP, and GGT activities was observed in the DEN/AAF-treated rats. Liver GSTs were similarly increased with DEN/AAF treatment. Tocotrienol supplementation attenuated the impact of the carcinogens in the rats.

Shamaan NA, Kadir KA, Rahmat A, Ngah WZ

Nutrition, 1998 12 3;14(11-12):846-52.
PMID: 9834927

The effects of vitamin C and aloe vera gel extract supplementation on induced hepatocarcinogenesis in male Sprague-Dawley rats (120-150 g) by diethylnitrosamine (DEN) and 2-acetylaminofluorene (AAF) was investigated. The severity of the carcinogenesis process was determined by measuring gamma-glutamyl transpeptidase (GGT) and the placental form of glutathione S-transferase (GSTP) histochemically in situ and in plasma and liver fractions. In addition, plasma alkaline phosphatase (ALP) and liver microsomal uridine diphosphate glucuronyl transferase (UDPGT) activity were also determined. Administration of DEN/AAF caused an increase in the surface area and number of enzyme-positive foci (both GGT and GSTP) compared with control. Supplementation of vitamin C or aloe vera gel extract to the cancer-induced rats suppressed this increase significantly (P < 0.05; P < 0.001). Increases in liver UDPGT, GGT, and GSTP activities were also observed with cancer induction that were again suppressed with either vitamin C or aloe vera gel supplementation. Plasma GGT in the DEN/AAF rats were determined monthly for the duration of the experiment and found to be reduced as early as 1 mo with aloe vera gel supplementation and 2 mo with vitamin C supplementation. In conclusion, vitamin C and aloe vera gel extract supplementation were found to be able to reduce the severity of chemical hepatocarcinogenesis.

Joishy SK, Bennett JM, Balasegaram M, MacIntyre JM, Falkson G, Moertel C, et al.

Cancer, 1982 Sep 15;50(6):1065-9.
PMID: 6286085

Twenty Malaysian patients with unresectable primary liver cell cancer were prospectively studied at the General Hospital, Kuala Lampur, and were compared for clinical features with an equal number each of African and American patients being studied by the Eastern Cooperative Oncology Group. The patients received intravenous 5-FU and oral MeCCNU which was used for the first time in an Asian country. Most of the Malaysian patients were Chinese, belonged to younger age groups, and presented with massive hepatomegaly, jaundice, and fever. Toxicity to MeCCNU invariably occurred in the form of leukopenia or thrombocytopenia, but none life threatening. Partial response was seen in 20% of Malaysians as compared to 16% in Americans and none in Africans. Malaysians achieved a median survival of 16 weeks compared to 28 weeks in Americans and only eight weeks in Africans. Malaysian Chinese patients were all HBc Ab + ve. Other factors which may have played an etiologic role in the induction of primary liver cancer included alcohol, Chinese herbal medicines, aflatoxin and habitual use of medicated rubbing oils.

Sulaiman SA, Abu N, Ab-Mutalib NS, Low TY, Jamal R

Future Oncol, 2019 Aug;15(22):2603-2617.
PMID: 31339048 DOI: 10.2217/fon-2018-0909

Aim: Micro and macro vascular invasion (VI) are known as independent predictors of tumor recurrence and poor survival after surgical treatment of hepatocellular carcinoma (HCC). Here, we aimed to re-analyze The Cancer Genome Atlas of liver hepatocellular carcinoma datasets to identify the VI-expression signatures. Materials & methods: We filtered The Cancer Genome Atlas liver hepatocellular carcinoma (LIHC) datasets into three groups: no VI (NVI = 198); micro VI (MIVI = 89) and macro VI (MAVI = 16). We performed differential gene expression, methylation and microRNA analyses. Results & conclusion: We identified 12 differentially expressed genes and 55 differentially methylated genes in MAVI compared with no VI. The GPD1L gene appeared in all of the comparative analyses. Higher GPD1L expression was associated with VI and poor outcomes in the HCC patients.

Fulltext Induction of Apoptosis and Cytotoxicity by Isothiocyanate Sulforaphene in Human Hepatocarcinoma HepG2 Cells

Kntayya SB, Ibrahim MD, Mohd Ain N, Iori R, Ioannides C, Abdull Razis AF

Nutrients, 2018 Jun 04;10(6).
PMID: 29866995 DOI: 10.3390/nu10060718

Glucoraphenin, a glucosinolate present in large quantities in radish is hydrolysed by myrosinase to form the isothiocyanate sulforaphene, which is believed to be responsible for its chemopreventive activity; however, the underlying mechanisms of action have not been investigated, particularly in human cell lines. The aim of the study is to assess the cytotoxicity of sulforaphene in HepG2 cells and evaluate its potential to enhance apoptosis. The cytotoxicity of sulforaphene in HepG2 cells was carried out ensuing an initial screening with two other cell lines, MFC-7 and HT-29, where sulforaphene displayed highest toxicity in HepG2 cells following incubation at 24, 48 and 72 h. In contrast, the intact glucosinolate showed no cytotoxicity. Morphological studies indicated that sulforaphene stimulated apoptosis as exemplified by cell shrinkage, blebbing, chromatin condensation, and nuclear fragmentation. The Annexin V assay revealed significant increases in apoptosis and the same treatment increased the activity of caspases -3/7 and -9, whereas a decline in caspase-8 was observed. Impairment of cell proliferation was indicated by cell cycle arrest at the Sub G₀/G₁ phase as compared to the other phases. It may be concluded that sulforaphene, but not its parent glucosinolate, glucoraphenin, causes cytotoxicity and stimulates apoptosis in HepG2 cells.

Oesophageal hepatoid carcinoma with liver metastasis, a diagnostic dilemma

Yahaya A, Wa Kammal WS, Abd Shukor N, Osman SS

Malays J Pathol, 2019 Apr;41(1):59-63.
PMID: 31025640

Alpha-fetoprotein (AFP)-producing carcinoma which microscopically mimics hepatocellular carcinoma (HCC) is a rare entity known as hepatoid adenocarcinoma (HC). They usually arise in the stomach, while oesophageal origin is only occasionally encountered. This tumour is highly aggressive and is associated with a poor prognosis. They frequently metastasise to the liver, thus giving rise to diagnostic difficulty, especially in cases where simultaneous oesophageal and liver mass are present. We reported a case of oesophageal hepatoid carcinoma with multiple liver metastasis, that was associated with an increased serum AFP. The distinction between HCC and HC is important because HC is more aggressive and has a poorer prognosis with limited therapeutic options. An extensive diagnostic work-up which include a thorough clinical history, radiological investigations (computed tomography or magnetic resonance imaging) as well as tissue biopsy supported by a panel of immunohistochemical markers are necessary to aid in the diagnosis of HC.

Effect of ovariectomy and sex hormone replacement on glutathione and glutathione-related enzymes in rat hepatocarcinogenesis

Hambali Z, Ngah WZ, Wahid SA, Kadir KA

Pathology, 1995 Jan;27(1):30-5.
PMID: 7603748

The effects of ovariectomy and hormone replacement in control and carcinogen treated female rats were investigated by measuring whole blood and liver glutathione (WGSH, HGSH), glutathione S-transferase (GST), glutathione peroxidase (GPx), and glutathione reductase (GRx) and histological evaluation. Hepatocarcinogenesis was induced by diethylnitrosamine and 2-acetylaminofluorene. In control rats not receiving carcinogen, ovariectomy significantly increased the GST and GRx activities. Replacement with either estrogen or progesterone reduced the GST activities to below intact female values whereas replacement of both hormones together brought the GST activities to that of intact females. GRx activities were brought to intact female values by replacement with estrogen or progesterone, either singly or in combination. Neither ovariectomy nor sex hormone/s replacement influenced the levels of WGSH, HGSH and GPx activities. Carcinogen administration to intact rats increased all the parameters measured. Ovariectomized rats treated with carcinogen showed lower GPx and GRx activities at 2 mths. However, replacement with either progesterone or combined estrogen and progesterone increased GPx and GRx activities to original values. On the other hand GST and GPx activities in ovariectomized rats which had carcinogen treatment were lower than intact rats after 5 mths. Replacement with hormones either singly or both brought GST and GPx activities up to intact rat levels receiving carcinogen. The levels of WGSH, HGSH and GRx activities (5 mths) in carcinogen treated rats were not influenced by ovariectomy and/or hormone/s replacement. The results from this study suggested that ovariectomy reduced the severity of hepatocarcinogenesis which was restored by sex hormone/s replacement.

GSK-3beta phosphorylation and alteration of beta-catenin in hepatocellular carcinoma

Ban KC, Singh H, Krishnan R, Seow HF

Cancer Lett, 2003 Sep 25;199(2):201-8.
PMID: 12969793

The aim of this study is to investigate the potential correlation between the expression of phosphorylated glycogen synthase kinase-3beta (phospho-GSK-3beta) and beta-catenin, and the mutations of beta-catenin gene at the consensus GSK-3beta phosphorylation site. The reason for this approach is to gain a better understanding of the molecular mechanisms of hepatocarcinogenesis in Malaysia. The expression of phospho-GSK-3beta and beta-catenin by immunohistochemistry and the mutations of beta-catenin were studied in 23 hepatocellular carcinoma (HCC) and surrounding tissues. Overexpression of phospho-GSK-3beta and beta-catenin was found in 12/23 (52.2%) and 13/23 (56.5%) in HCC tissues, 6/23 (26.1%) and 9/23 (39.1%) in surrounding tissues, respectively. Overexpression of beta-catenin in HCC tissues compared to the surrounding liver tissue was found to be higher in HCC tissues (p=0.015). In addition, we found that the expression of phospho-GSK-3beta was related with the accumulation of beta-catenin in surrounding tissues (p<0.05). The expression of phospho-GSK-3beta and its association with the development of HCC is reported for the first time. In addition, this is the first report from Malaysia which shows that there are no mutations at the GSK-3beta consensus phosphorylation sites on beta-catenin gene in all 23 paired HCC and surrounding tissues. This result differed from HCC in geographical areas with high aflatoxin exposure.

Potential biomarkers in NASH-induced liver cirrhosis with hepatocellular carcinoma: A preliminary work on roles of exosomal miR-182, miR-301a, and miR-373

Muhammad Yusuf AN, Raja Ali RA, Muhammad Nawawi KN, Mokhtar NM

Malays J Pathol, 2020 Dec;42(3):377-384.
PMID: 33361718

INTRODUCTION: Recent studies have published the roles of exosomal miRNAs in the pathogenesis of various type of malignancies and can be developed as potential biomarkers for diagnostic, prognostic and therapeutic purposes. The aim of this study was to identify the expression level of selected miRNAs (miR-182, miR-301a, and miR-373) in exosomes of the serum and ascitic fluid in patients with non-alcoholic steatohepatitis (NASH)-related liver cirrhosis with or without hepatocellular carcinoma (HCC).
MATERIALS AND METHODS: A literature search was performed to identify potential miRNAs involved in the pathogenesis of HCC. Unpaired serum and ascitic fluid were obtained from 52 patients with NASH related liver cirrhosis (n=26 for each group of with and without HCC). Exosomal miRNA was isolated from all samples. Expression levels of miR-182, miR-301a and miR- 373 were determined using quantitative real-time PCR.
RESULTS: Serum-derived exosomal mir-182, miR-301a and miR-373 were significantly up-regulated with fold change of 1.77, 2.52, and 1.67 (p< 0.05) respectively in NASH-induced liver cirrhosis with HCC as compared to NASH-induced liver cirrhosis without HCC. We identified the expression levels of ascitic fluid-derived exosomal mir-182, miR-301a, and miR-373 were significantly up-regulated with fold change of 1.6, 1.94 and 2.13 respectively in NASH-induced liver cirrhosis with HCC as compared to NASH-induced liver cirrhosis without HCC (p <0.05). There was poor correlation expression of all the selected exosomal miRNA between serum- and ascitic fluid-derived in HCC group.
CONCLUSIONS: This preliminary data showed significant increase in the expression levels of exosomal miR-182, miR-301a and miR- 373 in both serum and ascetic fluid suggesting the possible roles of these miRNAs as circulating biomarkers for NASH-induced liver cirrhosis with hepatocellular carcinoma.

Fulltext Growth of Hepatocellular Carcinoma into the Right Atrium with Associated Pulmonary Tumour Emboli

Amran, A.R., Ranganathan, S.

International Medical Journal Malaysia, 2006;5(1):1-5.
MyJurnal

Hepatocellular carcinoma (HCC) presenting with right atrial metastases and pulmonary tumour embolism is rare . Intracavitary cardiac metastasis is uncommon and metastasis to the right atrium is even less common. The majority of such cases are believed to be due to advanced HCC such as Stage III or IV, in which the progression rate is high, and in infiltrative HCC it tends to be associated with vascular invasion. The diagnosis of pulmonary intravascular tumour emboli is difficult to establish both clinically and with conventional radiographic studies. We report a case hepatocellular carcinoma associated with tumour thrombus in the inferior vena cava (IVC), right atrium and pulmonary tumour embolism detected with multidetector helical computerized tomography (MDHCT).

Fulltext The efficacy of pre-operative laparoscopy in the staging for gastric cancer

Kandasami P

International e-Journal of Science, Medicine & Education, 2012;6(Suppl 1):103-105.
MyJurnal

The only potential curative therapy for gastric cancer is the resection of both the tumor and the regional lymph nodes at the early stage of the disease. The majority of patients with gastric cancer in Malaysia have an advanced disease at initial diagnosis, and curative surgery is possible in less than 20% of operated cases. Acurate preoperative staging is crucial in determining the most suitable therapy and avoiding unnecessary attempts at curative surgery. While computed tomography remains as the most widely used imaging modality for gastric cancer staging, its ability to detect local invasion, peritoneal and liver metastases is limited. In the recent years laparoscopy has become an important component in the staging algorithm of gastric cancer. The aim of this review is to evaluate the efficacy of routine preoperative laparoscopic staging in the management of gastric cancer, and in particular describe the Malaysian experience.

PMID: 29693341

Clausena excavata Burm f. is used by traditional healers to treat cancer patients in South East Asia. The use of the
plant and its compounds is based on Asian folklore with little or no scientific evidence supporting the therapeutic efficacy
The current study aimed to determine the effect of pure clausenidin isolated from C. excavata on caspase-8-induced cell
death as well as angiogenesis in the HepG2 hepatocellular carcinoma cell line. Caspase-8 and extrinsic death receptor
protein expression was determined using spectrophotometry and protein profile arrays, respectively. Ultrastructural
analysis of clausenidin-treated cells was conducted using transmission electron microscopy. In addition, anti-angiogenic
effects of clausenidin were investigated by Western blot analysis. Clausenidin significantly (p<0.05) increased the
activity of caspase-8 and expression of protein components of the death inducing signaling complex (DISC) in HepG2
cells. Ultrastructural analysis of the clausenidin-treated HepG2 cells revealed morphological abnormalities typical of
apoptosis. Furthermore, clausenidin significantly (p<0.05) decreased the expression of vascular endothelial growth
factor (VEGF). Therefore, clausenidin is a potential anti-angiogenic agent which may induce apoptosis of hepatocellular
carcinoma cells.

Automatic liver tumor segmentation on computed tomography for patient treatment planning and monitoring

Moghbel M, Mashohor S, Mahmud R, Saripan MI

EXCLI J, 2016;15:406-23.
PMID: 27540353 DOI: 10.17179/excli2016-402

Segmentation of liver tumors from Computed Tomography (CT) and tumor burden analysis play an important role in the choice of therapeutic strategies for liver diseases and treatment monitoring. In this paper, a new segmentation method for liver tumors from contrast-enhanced CT imaging is proposed. As manual segmentation of tumors for liver treatment planning is both labor intensive and time-consuming, a highly accurate automatic tumor segmentation is desired. The proposed framework is fully automatic requiring no user interaction. The proposed segmentation evaluated on real-world clinical data from patients is based on a hybrid method integrating cuckoo optimization and fuzzy c-means algorithm with random walkers algorithm. The accuracy of the proposed method was validated using a clinical liver dataset containing one of the highest numbers of tumors utilized for liver tumor segmentation containing 127 tumors in total with further validation of the results by a consultant radiologist. The proposed method was able to achieve one of the highest accuracies reported in the literature for liver tumor segmentation compared to other segmentation methods with a mean overlap error of 22.78 % and dice similarity coefficient of 0.75 in 3Dircadb dataset and a mean overlap error of 15.61 % and dice similarity coefficient of 0.81 in MIDAS dataset. The proposed method was able to outperform most other tumor segmentation methods reported in the literature while representing an overlap error improvement of 6 % compared to one of the best performing automatic methods in the literature. The proposed framework was able to provide consistently accurate results considering the number of tumors and the variations in tumor contrast enhancements and tumor appearances while the tumor burden was estimated with a mean error of 0.84 % in 3Dircadb dataset.

Inferior vena cava and intra-cardiac invasion of hepatocellular carcinoma: a rare but catastrophic complication

Peter CA, Anand Swaroop U, Wong BS

Med J Malaysia, 2017 02;72(1):58-59.
PMID: 28255143

Intra-cardiac extension of hepatocellular carcinoma (HCC) is an uncommon but serious condition related to poor prognosis. We report a 57-year-old male diagnosed with HCC with intra-cardiac extension into the right atrium at presentation. There were no symptoms related to cardiac involvement and intra-cardiac extension was incidentally noted on radiological imaging. He was offered palliative treatment and succumbed to his disease within 50 days of first diagnosis.

Fulltext Spontaneous resolution of asymptomatic hepatic pseudoaneurysm post radiofrequency ablation

Ch'ng LS, Tazuddin EEM, Young B, Ali AFM

BJR Case Rep, 2016;2(2):20150306.
PMID: 30363592 DOI: 10.1259/bjrcr.20150306

Radiofrequency ablation (RFA) of a hepatic tumour is an established treatment option with an acceptable complication rate. Formation of a pseudoaneurysm after RFA of liver metastasis is an uncommon complication. We report the case of a 69-year-old female patient developing a hepatic pseudoaneurysm after RFA of liver metastasis. On a follow-up CT scan 6 weeks later, there was spontaneous resolution of the pseudoaneurysm. Hepatic pseudoaneurysms are usually treated owing to the risk of rupture. Invasive procedures or conservative management of an asymptomatic hepatic pseudoaneurysm is still the subject of debate. The spontaneous resolution of a hepatic pseudoaneurysm in our patient suggests that an asymptomatic pseudoaneurysm maybe observed for resolution instead of being treated at presentation.

Fulltext Hepatocellular carcinoma with disseminated skeletal muscle metastasis

Rahim EA, Noh MS, Ngah NA, Suraini MS, Yusof MM

Acta Radiol Open, 2017 Jul;6(7):2058460117716705.
PMID: 28811928 DOI: 10.1177/2058460117716705

Hepatocellular carcinoma (HCC) is the commonest primary tumor of the liver and carries a poor prognosis when diagnosed late or left untreated. Treatment relies heavily on the stage of the tumor when diagnosed. Extrahepatic metastasis is known to occur; these are mainly reported via autopsy studies or isolated case reports. Knowledge of extrahepatic metastasis is crucial in order to avoid unnecessary surgery. We report a rare case of a patient at our center, diagnosed to have HCC, who underwent treatment successfully, only to come back with extrahepatic metastasis to the skeletal muscles.

Suppression of the Viability and Proliferation of HepG2 Hepatocellular Carcinoma Cell Line by Konjac Glucomannan

Sawai S, Mohktar MS, Safwani WKZW, Ramasamy TS

Anticancer Agents Med Chem, 2018;18(9):1258-1266.
PMID: 29521251 DOI: 10.2174/1871520618666180307143229

BACKGROUND: Konjac Glucomannan (KGM) is a water-soluble dietary fibre extracted from Amorphophallus konjac K. Koch (Araceae). Konjac fibre has been clinically proven as an effective antioxidant agent in weight control but its traditionally known tumour suppression property remains to be explored.
OBJECTIVE: The main objective of this study is to determine the potential anti-proliferative effect of KGM on cancer and normal human liver cell lines, HepG2 and WRL68, respectively.
METHOD: HepG2 and WRL68 cells were treated with KGM, D-mannose, KGM-D-mannose and 5-fluorouracil. The morphological changes in those treated cells were observed. Cytotoxic effect of the treatments on cell viability and proliferation, and apoptosis genes expression were assessed by cytotoxicity assay, flow cytometry and RT-PCR analyses.
RESULTS: The results show that KGM treatment resulted in reduced viability of HepG2 cells significantly, in line with the apoptosis-like morphological changes. Up-regulation of BAX and down-regulation of BCL2 genes as reflected by high Bax to Bcl 2 ratio suggests that the inhibitory effect of KGM on HepG2 cells most likely via Bcl2/Bax protein pathway. Despite the effectiveness of standard drug 5-FU in suppressing the viability and proliferation of HepG2 cells, it however, exhibited no selective inhibition of cancer cells as compared to KGM.
CONCLUSION: Current findings suggested that KGM is a potential anti-cancer compound/drug entity, which could be an alternative preventive agent against liver cancer.
