Interventional radiological treatment of non-colorectal liver metastases

Transcatheter treatment was performed in 81 patients with unresectable non-colorectal liver metastases. Effectiveness increased in the following order: hepatic artery infusion--arterial chemoembolization--combined, arterial and portal vein oily chemoembolization. The mean survival rates for these methods were 8.2 +/- 5.3, vs 11.7 +/- 12.9 vs 13.6 +/- 6.8 mo, and 1-year survival rates 29% vs 46% vs 65%, respectively. Chemoembolization with doxorubicin-in-oil and gelatin sponge was the most effective technique. Interventional radiological procedures were effective in neuroendocrine liver metastases. The mean survival, 1- and 3-year survival rates were as high as 34 mo, 100% and 80%, respectively, for hepatic metastases from resected malignant carcinoid tumors. Also good results were achieved after chemoembolization of metastatic ovarian carcinoma and arterial infusion for gastric carcinoma metastatic to the liver. Transcatheter treatment was ineffective in liver metastases from pancreatic carcinoma, gallbladder cancer, and unknown (and non-resected) tumors. The initial results of the use of interventional radiological procedures in non-colorectal liver metastases are promising, so following clinical trails are needed.

Pancreastatin-like immunoreactivity in human carcinoid disease

Pancreastatin-like immunoreactivity has been demonstrated in human carcinoid tumors by immunohistochemistry and radioimmunoassay, employing antisera raised to a synthetic C-terminal fragment of porcine pancreastatin. Immunohistochemistry revealed intense immunoreactivity in all tumors. By radioimmunoassay, high concentrations of pancreastatin-like immunoreactivity were measured in carcinoid tumors arising from the fore-gut (mean +/- S.D. and range: 369 +/- 955 and 9.4-3670 pmol g-1, respectively, n = 14), mid-gut (mean +/- S.D. and range: 1354 +/- 1538 and 337-3978 pmol g-1, respectively, n = 5) and in metastases associated with mid-gut tumors (mean +/- S.D. and range: 684 +/- 739 and 31-2255 pmol g-1, respectively, n = 7), compared to corresponding normal tissues (less than 1.4 pmol g-1). Individuals with hepatic metastases and carcinoid syndrome had elevated circulating levels of pancreastatin-like immunoreactivity (mean +/- S.D. and range: 770 +/- 1249 and 42-4120 pmol l-1; n = 12), significantly above the normal, fasting range (mean +/- S.D. and range: 14.9 +/- 7.5 and 4-37.5 pmol l-1, respectively, n = 42). However, patients with non-metastatic carcinoid tumors (n = 4), who had been clinically cured after primary tumor resection, had plasma levels within the normal range. Chromatographic analysis of extracts of primary lung and ileal tumors, hepatic metastases from ileal tumors and plasma from individuals with carcinoid syndrome revealed molecular heterogeneity of pancreastatin-like immunoreactivity.     

Post-TACE Combination Therapy of Heparin and Octreotide Results in Decreased Tumor Metastasis in Extrahepatic Tumorigenesis

Primary hepatocarcinoma is the most common type of malignant tumor and a leading cause of cancer mortality. Standard treatment for patients with advanced primary hepatocarcinoma for whom surgery is not recommended includes transcatheter arterial chemoembolization (TACE). Within these patients 44% develop metastasis within 1 year. Thus, understanding the events underlying the recurrent tumors and developing therapies in conjunction with TACE would be of great benefit. Reducing tumor angiogenesis by combining the somatostatin analog octreotide with small doses of heparin is one approach in decreasing metastasis rates by targeting VEGF and heparinase, respectively. Given this, we investigated whether a heparin and octreotide combination treatment administered post-TACE would decrease the tumor metastasizing rate in primary hepatocarcinoma. A total of 147 patients diagnosed with primary hepatocarcinoma were admitted to the study and received 2–4 TACE treatments and were monitored for 1 year. Of these 84 received the heparin plus octreotide combination treatment and 63 did not (control group). All patients were monitored for adverse reactions, coagulation ability, and tumor metastasis. We found a significant decrease in the incidence of tumor metastasis in patients receiving the combination treatment post-TACE for up to 1 year with no significant toxic or adverse effects. Thus, we propose using the combination treatment of heparin and octreotide post-TACE in the treatment of recurrent tumorigenesis in primary hepatocarcinoma.

DynaCT对肝转移瘤介入治疗具有指导意义

为了探讨锥形束CT (DynaCT)在肝癌患者实施经导管肝动脉化疗栓塞(TACE)手术治疗中的指导作用、栓塞效果评估中的价值,本研究选取了2012年3月至2015年5月在本院实施TACE手术治疗的102例原发性肝癌或转移性肝癌患者进行研究。通过对102例患者病灶进行手术前螺旋CT检测、术中数字减影血管造影(DSA)及DynaCT检测,并对比DSA与DynaCT对肝癌病灶、供血动脉、术后栓塞效果的检测结果。本研究发现术前普通螺旋CT共计检出病灶105个,术中DSA检出病灶数目176个,DynaCT术中检出肿瘤病灶285个;DynaCT和DSA的平均检出病灶数目均显著的高于普通螺旋CT (p<0.05),DynaCT平均检出病灶数目均显著的高于DSA (p<0.05);DynaCT的病灶供血动脉检出率为86.67%,显著地高于DSA (55.68%)(p<0.05);DynaCT检出的285个病灶对栓塞效果评估结果与实际栓塞效果一致的有271个病灶(95.09%),DSA评估结果与实际结果一致的有138个病灶(78.41%),DynaCT对于TACE术后效果评估的一致性高于DSA (p<0.05)。本研究表明,DynaCT在肝癌患者实施TACE手术治疗中能够更有效的发现病灶,指导栓塞操作。     

Hepatic Parenchymal Changes following Transcatheter Embolization and Chemoembolization in a Rabbit Tumor Model

Objective

To compare the effects of transcatheter arterial chemoembolization (TACE) with transcatheter arterial embolization (TAE) on liver function, hepatic damage, and hepatic fibrogenesis in a rabbit tumor model.

Materials and Methods

Thirty-nine New Zealand white rabbits implanted with VX2 tumors in the left liver lobes were randomly divided into three groups: TAE, TACE, and control group. In the TAE group (n = 15), polyvinyl alcohol particles (PVAs) were used for left hepatic artery embolization. In the TACE group (n = 15), the tumors were treated with left hepatic arterial infusions of a suspension of 10-hydroxycamptothecin and lipiodol, followed by embolization with PVAs. In the control group (n = 9), the animals received sham treatment with distilled water. Serum and liver samples were collected at 6 hours, 3 days and 7 days after treatment. Liver damage was measured using a liver function test and histological analyses. Liver fibrogenesis and hepatic stellate cell (HSC) activation were evaluated using Sirius Red and anti-alpha-smooth muscle actin (α-SMA) immunohistochemical stains.

Results

TACE caused liver injury with greater increases in serum alanine aminotransferase and aspartate aminotransferase levels on day 3 (P<0.05). Histological analyses revealed increased hepatic necrosis in adjacent non-tumorous liver tissue from day 3 compared to the TAE group (Suzuki score of 2.33±1.29 versus 1.13±1.18, P = 0.001). HSC activation and proliferation were significantly increased in the TACE group compared to the control group at 3 and 7 days after treatment (0.074±0.014 vs. 0.010±0.006, and 0.088±0.023 vs. 0.017±0.009, P<0.05). Sirius Red staining demonstrated a statistically significant increase in collagen deposition in the livers in the TACE group 7 days after embolization compared to the control group (0.118±0.012 vs. 0.060±0.017, P = 0.05).

Conclusion

The results of this animal study revealed that TACE induced prominent hepatocellular damage and hepatic fibrogenesis, which compromised liver function and may be responsible for chronic liver decompensation.     

Neuroendocrine tumors of gastrointestinal tract in own material

Neuroendocrine tumors are rare gastrointestinal tract disorders, in which diagnosis and treatment are often difficult. The aim of the paper is to present two cases of patients with neuroendocrine tumor of gastrointestinal tract, who underwent surgical procedure in II Department of General and Gastroenterological Surgery of Medical University of Bia?ystok in 2005. A 63-year-old female patient with primary diagnosis of neuroendicrine tumor metastases in liver was not successfully investigated for primary tumor in the preoperative period. The laparotomy procedure indicated the malignant neuroendocrine tumor in the terminal ileum and metastases to the liver and to the greater omentum. The right hemicolectomy and liver metastatic segment VII and VIII resection were performed. The neurological disturbances of obscure origin were observed in the postoperative period and the patient suddenly died on the 15(th) day after surgery. A 57-years-old male patient was operated on for lymph node recurrence of gastric tumor. Pathologic examination of tissue sample revealed the diagnosis of carcinoid. The patient underwent subtotal gastric resection for a pyloric ulcer, diagnosed as Adenocarcinoma G2 pT2N0M0 6 years before. Liver and abdominal node metastases, confirmed by octreoscan, were observed after lymphadenectomy, The treatment of somatostatin analogues (LAR octreotide) was used. In spite of therapy the patient died. The authors present their own experiences and show the preoperative diagnostic difficulties in patients with neuroendocrine gastrointestinal tumors. Unexpected neurological complications in the treatment course were described.     

Lactate Dehydrogenase Is an Important Prognostic Indicator for Hepatocellular Carcinoma after Partial Hepatectomy

Preoperative serum lactate dehydrogenase (LDH) has been used as a prognostic indicator for patients with hepatocellular carcinoma (HCC) treated with sorafenib or undergoing transcatheter arterial chemoembolization, but its significance in predicting survival of HCC patients who received curative resection remains undefined. A total of 683 patients with histopathologically confirmed HCC were enrolled in this study. The prognostic significance of preoperative serum LDH was determined by Kaplan-Meier analysis and a Cox proportional hazards regression model. The association between the preoperative serum LDH and clinicopathological parameters was evaluated by the χ² test or linear regression analysis when appropriate. Higher preoperative serum LDH level was associated with worse prognosis. In a multivariate Cox proportional hazards analysis, the preoperative serum LDH level could predict overall survival and recurrence independently. Higher preoperative serum LDH level is associated with the elevated serum alpha-fetoprotein, the presence of hepatitis B surface antigen, larger tumor size, the presence of macrovascular invasion, the advanced tumor–lymph node–metastasis stage, worse tumor differentiation, and Child-Pugh B. Preoperative serum LDH level was an inexpensive, simple, convenient, and routinely measured biomarker exhibiting a potential to select patients at high risk with poor clinical outcome for appropriate treatment strategies.     

Cytologic findings in primary malignant carcinoid tumor of the cervix. Including immunohistochemistry and electron microscopy performed on cervical smears

The cytologic findings in a primary malignant carcinoid tumor of the cervix are presented. In addition to the presence in the smears of cells suggestive of squamous carcinoma and adenocarcinoma, which led to an initial diagnosis of adenosquamous carcinoma, there were multinucleated giant cells with prominent, reddish nucleoli, finely granular chromatin and grayish-blue to eosinophilic cytoplasm, as well as smaller pleomorphic cells, against a tumor-diathesis type of background. Immunocytochemistry performed on the cervical smears showed the presence of serotonin, and ultrastructural analysis revealed abundant intracytoplasmic, membrane-bound granules in malignant cells, thus confirming the diagnosis of a carcinoid tumor.

Pancreatic islet cell tumors metastatic to the liver: treatment by hepatic artery chemo-embolization

The embolization of hepatic metastases of pancreatic islet cell tumors achieves a tumor necrosis without liver failure owing to double hepatic blood supply. The arterial chemotherapy performed at the same time delivers a large amount of cytotoxic agent directly into the tumor. Tumor bulk reducing and decreasing of production of pharmacologically active substances may be obtained to some degree. Although an objective documentation of the therapeutic effect is difficult to obtain, several series emphasize that the embolization provides a partial and transient palliative remission. Therefore, the chemo-embolization should be included in a multidisciplinary approach of metastatic endocrine malignancies in combination with surgical resection, systemic antineoplastic chemotherapy, and antihormonal therapy.     

Traitement médical des tumeurs endocrines digestives

Gastroenteropancreatic neuroendocrine tumors constitute a highly heterogeneous group of tumors with very different prognoses. It is important to distinguish between the well-differentiated neuroendocrine tumors (carcinoid tumors affecting the gastrointestinal tract and pancreatic endocrine tumors), which generally progress slowly, and the poorly differentiated endocrine tumors, which are characterized by being aggressive and of rapid progression. The treatment of the poorly differentiated forms is essentially based on chemotherapy, although prognosis remains poor. The well-differentiated forms require a more complex approach – depending on the site of the primary tumor, staging, the resectability of the lesions, and disease spread – and should therefore be defined within a multidisciplinary setting. The treatment of choice remains surgical excision of the primary tumor and metastases. No additional treatment has been demonstrated to be effective. For functional tumors, symptomatic treatment with a somatostatin analog for carcinoid tumors or a protein pump inhibitor for gastrinoma must be started rapidly to reduce the complications related to hormone secretion. For metastatic disease or for tumors that are not amenable to complete resection, several options can be proposed: careful monitoring, chemoembolization of liver metastases, systemic chemotherapy, or enrollment in therapeutic protocols offering targeted therapies. Stepwise introduction of these various therapies prolongs survival, even in metastatic disease.     

Embolization of the hepatic artery in cases of atypical anatomical structural variants in patients with malignant liver tumors

Therapeutic embolization of the hepatic artery was performed in 60 patients with nonresectable malignant liver tumors. Atypical topographical anatomical variants of the arterial system of the liver were revealed in 10 of them (16.7%). In 8 patients two hepatic vessels, one coming out of the celiac artery, the other--out of the upper mesenterial or left gastric artery supplied a tumor with blood. In three of them one vessel was embolized, in five patients both arteries were embolized. The blocking of the entire blood flow of a tumor brought about a positive clinical effect in all the patients. Embolization of one blood-supplying artery alone led to no improvement. A conclusion was made of a necessity to achieve arterial devascularization of the entire tumor tissue area during intravascular therapy.     

Sarcomatoid hepatocellular carcinoma (SHC): a case report

Background

Sarcomatoid hepatocellular carcinoma (SHC) is a rare malignant hepatic tumor. Recurrent interventional therapies such as transcatheter arterial chemo-embolization (TACE), radiofrequency ablation (RFA), and percutaneous ethanol injection have been reported previously utilized in a majority of SHC cases. To date, the exact pathogenic mechanisms underlying sarcomatoid transformation of hepatocellular carcinoma (HCC) remain unknown.

Case presentation

In this study, we report a 68-year-old female SHC patient admitted to our hospital due to discrete abdominal distention for more than 20 days. Abdominal computed tomography (CT) with tri-phase enhancement revealed portal vein tumor thrombi (PVTT) and a left hepatic lobe lesion measuring 110.0 mm?×?160.0 mm. The patient subsequently underwent liver resection, after which pathological examination revealed proliferation of spindle-shaped SHC cells. A sarcomatoid, T4 stage carcinoma was eventually diagnosed. Forty-seven days after the operation, tri-phase enhanced CT detected extensive lesions in the liver, spleen, peritoneum, omentum majus, and mesentery, indicating SHC recurrence and metastases. Combination chemotherapy with pirarubicin and cisplatin was initiated for 1 cycle, but terminated due to resultant severe myelosuppression and medication intolerance. The patient was lost to therapy after 3 months of follow-up.

Conclusions

This case is unique because of hepatitis C virus infection. We should consider the possibility of this disease in patients with atypical clinical presentation.

     

肝癌动脉化疗给药方式和剂型对药物代谢动力学影响研究

肝癌是全世界最常见的恶性肿瘤之一,而经导管肝动脉化疗栓塞（TACE）是治疗不能手术的中晚期肝癌的标准手段。从给 药方式上而言,相对于静脉系统化疗及单纯的肝动脉灌注,肝动脉化疗栓塞术,尤其是进行明胶海绵补充栓塞,可明显改善物代 谢动力学参数,既减少外周药物浓度和非靶器官毒性,又能增加局部药物浓度从而增强药物的治疗效果。从剂型上而言,阿霉素 碘化油乳剂能明显降低血药峰值浓度,并能选择性分布于肝脏肿瘤内,达到靶向治疗肝癌的目的。加用明胶海绵补充栓塞,上述 作用会更加明显。肝动脉化疗药微囊栓塞也能取得较明显的物代谢动力学优势,缓释、增加局部浓度、延长作用时间和减轻药物 不良反应。无论外周血药峰值浓度（Cmax）还是曲线下面积（AUC）,载药洗脱微球(DEB)栓塞均显著低于阿霉素碘化油乳剂栓塞, 从而取得比传统的化疗栓塞更好的肝癌治疗效果。对不同给药方式及载药剂型的物代谢动力学研究,将对不断提高TACE的疗 效和安全性有重要意义。     

High serum alkaline phosphatase cooperating with MMP-9 predicts metastasis and poor prognosis in patients with primary osteosarcoma in Southern China

Background

A malignant fibrous histiocytoma is a soft tissue tumor that most commonly occurs in the extremities, but rarely involves the liver. The clinical characteristics and therapeutic experiences of primary hepatic malignant fibrous histiocytoma are still limited.

Methods

Two cases of primary hepatic malignant fibrous histiocytoma were analyzed retrospectively, and all the literature concerning primary hepatic malignant fibrous histiocytoma was analyzed.

Results

In China, a total of 76 cases had been reported, among which 50 were men, with a male to female ratio of 1.9:1. Mean age of the patients was 51.0 years old, and more than 85 percent were older than 40 years. 82.9 percent (63/76) of hepatic MFH were solitary lesions, with tumor size ranging from 2.5 to 23.5 cm (average 10.3 cm). Major clinical presentation (78.4%) was abdominal pain or discomfort, accompanied with some other non-specific symptoms such as malaise, anorexia, weight loss, jaundice and fever, and small cases (14.9%) were asymptomatic. Computed tomography and ultrasound usually revealed the location of lesions. The rate of pre-operative misdiagnosis was extremely high, and 14.9 percent of patients were even misdiagnosed as a benign liver cyst, liver abscess or hematoma. Integrated resection was performed among the most cases (49/68), among which only a few ones (12 cases) were introduced to have no recurrence or metastasis or be still alive with no detail information provided, while among the cases with palliative operation or only a biopsy, the cases that were followed-up all died.

Conclusions

Hepatic malignant fibrous histiocytoma is a rare malignant mesenchymal tumor. The variable features of clinical presentations and images make the diagnosis difficult. Though the prognosis of primary hepatic malignant fibrous histiocytoma was rather poor, integrated resection might provide a few cases a good opportunity for surviving, suggesting that surgery might be an effective treatment.
