Achievable complete remission of advanced non-small-cell lung cancer: Case report and review of the literature.

Surgery is the first choice of treatment for patients with non-small-cell lung cancer (NSCLC), but few patients can be treated surgically because of either advanced disease or poor pulmonary function. Other therapies include radiotherapy and chemotherapy, as well as complementary and alternative therapies, usually with disappointing results. Bronchial artery infusion (BAI) is a manageable and effective method for treating advanced NSCLC. Outcome is good by BAI due to its repeatability and low toxicity. Icotinib hydrochloride is a newly developed and highly specific epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor and has been safely and efficiently used to treat advanced NSCLC. We herein report a 73-year-old patient with chronic cough, who was diagnosed with advanced NSCLC with the EGFR mutation of L858R substitution in exon 21, and treated with the combination of oral icotinib and BAI chemotherapy as the first-line therapy, which resulted in a satisfactory clinical outcome. Complete remission of advanced NSCLC can be achieved using the combination of oral icotinib and BAI chemotherapy.

Cautiously using natural medicine to treat liver problems.

Natural medicine is a system of therapy that administrates natural agents and their derivatives to treat human diseases. This medicine has been used to treat many kinds of human diseases for thousands of years. The treatment protocols of natural medicine are integrative in nature, and are required to utilize the most appropriate therapies to address the needs of the individual patient. Because of the relative convenience, safety and efficacy, natural medicine is now increasing worldwide. Naturopathic doctors are licensed in many areas of the world and regulated partly by law in these areas, which is quite different from various other forms of complementary and alternative medicine. Liver diseases, such as hepatitis, liver cirrhosis and liver carcinoma, are serious health problems worldwide. Nearly half of the natural agents used in treatment of liver diseases today are natural products and their derivatives. Although natural medicine is beneficial and safe, physicians should pay close attention to the potential side-effects of the naturopathic agents, which lead to liver injury, interstitial pneumonia and acute respiratory failure. Therefore, when administrating naturopathic protocols to patients for the treatment of liver diseases, we should try our best to prevent and avoid as much as possible the negative impact of these medicines. This article highlights the current practice and recommended improvement of natural medicines in the treatment of liver diseases and gives some specific examples to emphasize the prevention and management of adverse reactions of the natural agents and suggests that natural medicine should be cautiously used to treat liver problems.

Plants Consumption and Liver Health.

The liver is a very important organ with a lot of functions for the host to survive. Dietary components are essential for and can be beneficial or detrimental to the healthy or diseased liver. Plants food is an essential part of the human diet and comprises various compounds which are closely related to liver health. Selected food plants can provide nutritional and medicinal support for liver disease. At the present, the knowledge of the effects of plants on the liver is still incomplete. The most urgent task at the present time is to find the best dietary and medicinal plants for liver health in an endless list of candidates. This review article updates the knowledge about the effects of plants consumption on the health of the liver, putting particular emphasis on the potential beneficial and harmful impact of dietary and medicinal plants on liver function.

A current update on the rule of alternative and complementary medicine in the treatment of liver diseases.

There is a vast body of knowledge which is ever-increasing about the treatment of liver disease with alternative and complementary medicine for which hundreds of thousands of literatures have been documented. Liver disease is a general term. This term covers all the potential problems that cause the liver to fail to perform its specified operations. Liver disease has a variety of presentations and causes a great public health problem worldwide which threatens the wellness of billions of people. Incidences of many types of liver disease are currently rising. Although there is still a debate about the entity of alternative and complementary medicine, it is now widely used and it is improving. And it covers the shortages and compensates for the weaknesses of conventional methods in the treatment of liver diseases. Alternative and complementary medicine for liver diseases provides benefits by regulating immunity, controlling disease progression, improving quality of life, and prolonging survival. This paper reviews the increasing interest and growing research into alternative and complementary medicine for liver diseases, with a look at the rough classification, principle of management, evidence-based applications, and issues for prescription and perspectives.

Role of antiviral therapy in the management of hepatocellular carcinoma.

Globally, hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection leads to liver fibrosis and cirrhosis, which in turn causes resultant hepatocellular carcinoma (HCC). Frequently, HCC recurs very soon even after a potentially curative treatment such as surgical interference or locoregional ablative therapies. Chronic HBV/HCV infection is often responsible for this recurrence, through secondary carcinogenesis. Antiviral therapy after a curative treatment of HCC plays an important role in preventing or delaying recurrence and improves survival in patients with HBV/HCV infection-related HCC. This article reviews the worldwide epidemiology of HBV/HCV infection, the association of viral infection with HCC, the mechanism of hepatitis virus-related hepatocarcinogenesis, and the paramount importance of antiviral therapy in the management of HCC.

Sorafenib: activity and clinical application in patients with hepatocellular carcinoma.

INTRODUCTION: Sorafenib is a novel oral bis-aryl urea compound that has proven survival benefit in patients with advanced hepatocellular carcinoma (HCC), for which several therapies are currently available with unsatisfactory results. Sorafenib is the first compound to demonstrate a significant effect on survival in HCC. AREAS COVERED: Our experience in the clinical application of sorafenib is reviewed in conjunction with relevant publications in the literature. Based on ex vivo and in vivo experiments, we conclude that sorafenib plays an important role in blocking tumor cell proliferation, inducing apoptosis, and reversing multidrug resistance. Antitumor activities were observed in multiple tumor types in ongoing randomized Phase III studies. Toxicity was observed as tolerable. On 16 November 2007, sorafenib was approved by the United States Food and Drug Administration for the treatment of unresectable HCC, based on the results of an international, multicenter, randomized, double-blind, placebo-controlled trial in patients with unresectable, biopsy-proven HCC. EXPERT OPINION: With the approval of sorafenib being given the significance of a milestone, systemic treatment of HCC is no longer regarded as ineffective. The tyrosine kinase inhibitor, sorafenib, gives us new hope for successful cancer therapy.

Correlation between tumor perfusion and lipiodol deposition in hepatocellular carcinoma after transarterial chemoembolization.

PURPOSE: To study the correlation of tumor perfusion with lipiodol deposition in hepatocellular carcinoma (HCC) after transarterial chemoembolization with multidetector computed tomography (MDCT) perfusion imaging. MATERIALS AND METHODS: MDCT perfusion imaging was performed in 24 patients with HCC 1 to 7 days before chemoembolization. The computed tomography (CT) perfusion parameters, such as hepatic arterial perfusion (HAP), hepatic portal perfusion (HPP), total liver perfusion (TLP), and hepatic arterial perfusion index (HAPI), were calculated with the slope method. The follow-up CT scans (noncontrast) were performed 4 weeks after chemoembolization to analyze lipiodol deposition. The lipiodol deposition in the tumor was classified into three grades and compared with CT perfusion parameters before chemoembolization. RESULTS: The HAP and TLP of tumors before chemoembolization were correlated with the grades of lipiodol deposition in tumors after chemoembolization (r = 0.768, P < .0001 and r = 0.616, P = .001, respectively). However, the HPP and HAPI of the tumors were not related to the grades of iodized oil deposition (r = 0.227, P = .286 and r = 0.111, P = .607, respectively). Higher HAP was correlated with better lipiodol deposition, and lower HAP was correlated with poorer lipiodol deposition. CONCLUSIONS: MDCT perfusion imaging has the potential to help select more appropriate patients with HCC for chemoembolization.

Gamma knife-treated hepatoma: case of obstructive jaundice and management.

Gamma knife therapy is becoming more frequently applied in solid tumor treatment. This article reports a unique case of severe obstructive jaundice arising as a complication of treatment of hepatoma at the hepatic hilum using a gamma knife.While planning an intervention, some images seem to promise success but actually lead to failure. Radiation damage to specific organs is difficult to predict because of several variables. Radiation-induced fibrosis and necrosis are the most common long-term adverse effects of radiotherapy; they are usually considered irreversible and result in induration and firmness of the tissue.To minimize radiation fibrosis, accurate patient positioning and tumor relocalization are essential for gamma knife use in the liver and other extracranial sites. Even when practiced frequently, any intervention must be delivered with caution if the liver has been treated with radiation. Otherwise, even with much experience, the unwary doctor can be trapped by deceptive images.

Traditional Chinese medicine plus transcatheter arterial chemoembolization for unresectable hepatocellular carcinoma.

OBJECTIVES: To compare the efficacy and safety of Traditional Chinese Medicine (TCM) plus transcatheter arterial chemoembolization (TACE) with that of TACE alone (therapy I versus therapy II, respectively) in treating unresectable hepatocellular carcinoma (UHCC) through a meta-analysis of all available randomized controlled trials. METHODS: Literature retrieval was conducted using the Cochrane Library, MEDLINE, EMBASE, CBMdisk, and CNKI in any language. Meta-analysis was performed on the results of homogeneous studies. Analyses subdivided by TACE frequency (subgroup A, <3 times; subgroup B, > or =3 times) were also performed, but were not done for both therapy I and therapy II. RESULTS: Based on our search criteria, we found 37 trials involving 2653 patients. Our results showed that therapy I, compared with therapy II, improved patient survival, quality of life, alleviation of symptoms, and tumor response, and was thus more therapeutically beneficial. Further analysis showed that subgroup A proved to be better for patients' survival and alleviation of symptoms, while the two subgroups were similar in improved tumor response. No serious adverse events were reported. CONCLUSIONS: Therapy I benefited patients with UHCC. Subgroup A improved the survival of patients and the amelioration of symptoms more than subgroup B. As in some trials, there were flaws in the methodological quality, and the data therefore have a risk of bias and of being insufficient for determining the effects of therapy I and subgroup A. Hence, further large-scale trials are warranted.

Arterial chemotherapy and conformal radiation abolish malignant biliary obstruction.

Malignant biliary obstruction has been a challenge to clinical practitioners, especially when it is serious and complete. Chemotherapy or radiation alone is often unsuccessful. In this study, the authors report a 59-year-old patient with complete common bile duct obstruction caused by cholangiocarcinoma who was treated with arterial chemotherapy followed by 3-dimensional conformal radiation, which resulted in a good clinical outcome.

Interventional treatments for hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most frequent primary malignant tumors in the world. Hepatic resection and liver transplantation are considered optimal for potential treatment of HCC. However, only 20% of HCCs can be surgically treated. And most of surgically-noneligible patients have to receive interventional managements including local ablation and transarterial chemoembolization (TACE). In this paper, we review the interventional treatments of HCC. DATA SOURCES: A literature search of PubMed database was conducted and research articles were reviewed. RESULTS: Percutaneous ethanol injection (PEI) is usually applied to small HCC for a complete necrosis. Radiofrequency ablation, an alternative to PEI, also causes tumor necrosis and needs fewer times of ablation. Other methods such as acetic acid injection, laser, microwave, etc have enriched local ablation for HCC. High intensity focus ultrasound (HIFU) is thought to be promising. TACE, another common modality, can improve the survival rate of patients with HCC. The newly developed embolic agents and adjuvant rAd-p53 gene therapy are well reported. CONCLUSIONS: Surgically-noneligible HCC can be treated with interventional procedures. Each method has its advantages and disadvantages. However, it is still pressing to develop ablative methods as well as new embolic agents for a better prognosis of HCC.

A case report of hepatic veno-occlusive disease after ingesting dainties.

Hepatic veno-occlusive disease (HVOD) is rarely encountered and easily misjudged as Budd-Chiari syndrome. It is often related to stem cell transplantation in recent years. We report a case of HVOD that is related to ingestion of some palatable local dishes. The diagnosis was confirmed by liver biopsy pathology with specific observation of inflammatory changes and fibrosis of venules intima, dilated sinusoids and central veins. Chronic diarrhea is unique for this case as a result of ingesting harmful stuffs. This case demonstrated that supervision and instruction of food recipe and traditional medicine are crucial, and prompt diagnosis, supportive care and specific treatment are essential to decreasing the morbidity and mortality of HVOD.

[Anticarcinogenic effect of 20(R)-ginsenoside Rg3 on induced hepatocellular carcinoma in rats].

OBJECTIVE: To explore the anticarcinogenic mechanism of 20(R)-ginsenoside Rg3 in induced liver tumor in SD rat. METHODS: Thirty-five SD rats with induced hepatocellular carcinoma were divided into a control group and 3 dosage groups according to the dosing levels of 20(R)-ginsenoside Rg3. The tumour volume was measured by MR imaging. The apoptotic rat and S-phase fraction and diploid of tumor cell were measured with flow cytometry. Protein expression of PCNA and TNF were evaluated with immunohistochemistry. RESULTS: There was significant difference in tumour volume between the high dosage group and the control group. The average apoptotic rates were 11.08+/-3.78, 13.57+/-3.34, 27.35+/-16.04 and the S-phase fractions were 23.98+/-9.44, 19.73+/-6.62, 14.09+/-3.48 in the low-, medium-, and high-dosage groups respectively. The apoptotic rate was significantly higher in the high-dosage group than in the medium-dosage group and low-dosage group. Before-after comparison showed that the anti-proliferative effects of 20(R)-ginsenoside Rg3 were significant in three treatment groups. The higher positive rats of protein expression with PCNA and TNF were significant difference in the high-dosage group compared to those in the low-dosage group. No significant difference between the medium-dosage group and the low-dosage group. CONCLUSION: 20(R)-ginsenoside Rg3 can noticeably inhibit the proliferation of tumor cells, and efficaciously induce the apoptosis and facilitate necrosis of the tumor cells, and there appears to be a dose dependent effect.

Detection of hypervascular hepatocellular carcinoma: Comparison of multi-detector CT with digital subtraction angiography and Lipiodol CT.

AIM: The purpose of this study was to compare the diagnostic accuracy of biphasic multi-detector row helical computed tomography (MDCT), digital subtraction angiography (DSA) and Lipiodol computed tomography (CT) in detection of hypervascular hepatocellular carcinoma (HCC). METHODS: Twenty-eight patients with nodular HCC underwent biphasic MDCT examination: hepatic arterial phase (HAP) 25 s and portal venous phase (PVP) 70 s after injection of the contrast medium (1.5 mL/kg). They also underwent hepatic angiography and intra-arterial infusion of iodized oil. Lipiodol CT was performed 3-4 wk after infusion. MDCT images were compared with DSA and Lipiodol CT images for detection of hepatic nodules. RESULTS: The three imaging techniques had the same sensitivity in detecting nodules >20 mm in diameter. There was no significant difference in the sensitivity among HAP-MDCT, Lipiodol CT and DSA for nodules of 10-20 mm in diameter. For the nodules <10 mm in diameter, HAP-MDCT identified 47, Lipiodol CT detected 27 (chi2 = 11.3, P = 0.005<0.01, HAP-MDCT vs Lipiodol CT) and DSA detected 16 (chi2 = 9.09, P = 0.005<0.01 vs Lipiodol CT and chi2 = 29.03, P = 0.005<0.01vs HAP-MDCT). However, six nodules <10 mm in diameter were detected only by Lipiodol CT. CONCLUSION: MDCT and Lipiodol CT are two complementary modalities. At present, MDCT does not obviate the need for DSA and subsequent Lipiodol CT as a preoperative examination for HCC.

Successful management of a benign anastomotic colonic stricture with self-expanding metallic stents: a case report.

AIM: To assess the effectiveness of and complications associated with metallic stent placement for treatment of anastomotic colonic strictures. METHODS: A 46-year-old man undergoing two procedures of surgery for perforation of descending colon due to a traffic accident presented with pain, abdominal distention, and inability to defecate. Single-contrast barium enema radiograph showed a severe stenosis in the region of surgical anastomosis and the patient was too weak to accept another laparotomy. Under fluoroscopic and endoscopic guidance, we placed two metallic stents in the stenosis site of the anastomosis of the patient with anastomotic colonic strictures. RESULTS: In this case of postsurgical stenosis, the first stent relieved the symptoms of obstruction, but stent migration happened on the next day so an additional stent was required to deal with the stricture and relieve the symptoms. CONCLUSION: This case confirms that metallic stenting may represent an effective treatment for anastomotic colonic strictures in the absence of other therapeutic alternatives.

Hepatocellular carcinoma treated with interventional procedures: CT and MRI follow-up.

In the past decade, a variety of interventional procedures have been employed for local control of hepatocellular carcinoma (HCC). These include transcather arterial chemoembolization (TACE) and several tumour ablation techniques, such as percutaneous ethanol injection (PEI), radio-frequency ablation (RFA), or percutaneous microwave coagulation therapy (PMC), laser-induced interstitial thermotherapy (LITT), etc. For a definite assessment of the therapeutic efficacy of interventional procedures, histological examination using percutaneous needle biopsy may be the most definite assessment of the therapeutic efficacy of interventional therapy, however, it is invasive and the specimen retrieved does not always represent the entire lesion owing to sampling errors. Therefore, computed tomography (CT) and magnetic resonance imaging (MRI) play a crucial role in follow-up of HCC treated by interventional procedures, by which the local treatment efficacy, recurrent disease and some of therapy-induced complications are evaluated. Contrast enhanced axial imaging (CT or MR imaging) may be the most sensitive test for assessing the therapeutic efficacy. The goal of the review was to describe the value of CT and MRI in the evaluation of interventional treatments.
