Abstract
RATIONALE Peripheral primitive neuroectodermal tumor (PNET) is a kind of small round cell tumor derived from primitive neuroectodermal tumor. PATIENT CONCERNS PNET is a highly malignant tumor that is subordinated to Ewing sarcoma. It occurs predominantly in soft tissue and bone and rarely in the bronchi and lung. Traditional surgery, radiotherapy, and chemotherapy are used for the treatment of PNET, but are usually ineffective. DIAGNOSES There was a rare case of a 17 year-old man diagnoses with primary pulmonary PNET. INTERVENTIONS The patient was treated by the remedy treatment with thalidomide after the poor effect of conventional radiotherapy and chemotherapy. OUTCOMES The patient survived without disease progression for 15 months and was in stable condition. LESSONS Thalidomide provides a choice for maintenance therapy in PNET.

Abstract
The inference to stem cells has been found in ancient myths and the concept of stem cells has existed in the fields of plant biology, developmental biology and embryology for decades. In the field of cancer research, the stem cell theory was one of the earliest hypotheses on the origin of a cancer from a single cell. However, an opposing hypothesis had it that an adult differentiated somatic cell could "de-differentiate" to become a cancer cell. Only within the last decade, via the "cloning" of Dolly, the sheep, did the field of stem cell biology really trigger an exciting revolution in biological research. The isolation of human embryonic stem cells has created a true revolution in the life sciences that has led to the hope that these human stem cells could lead to (a) basic science understanding of gene regulation during differentiation and development; (b) stem cell therapy; (c) gene therapy via stem cells; (d) the use of stem cells for drug discovery; (e) screening for toxic effects of chemicals; and (f) understand the aging and diseases of aging processes.

Abstract
Angiogenesis has long been recognized as an essential element in tumor growth. Since the conception of antiangiogenesis for cancer therapeutics, great strides have been made in understanding the molecular biology underlying angiogenesis, both in cancer and in physiology. By capitalizing on these advancements through bench-to-bedside research, potent antiangiogenic agents have been developed and tested. To date, the clinical results of most of these antiangiogenic agents have not met expectations. Even with the most successful agents, such as bevacizumab, used either as single agents or in combination with chemotherapy, gains in overall survival of cancer patients have been modest in most cases. In this article, the authors present the evolving views of antiangiogenic therapy, review recent experimental and clinical studies on antiangiogenesis, and address the fundamental role of hypoxia in tumor progression, which may be key to improving the efficacy of antiangiogenic therapy.

Abstract
The discovery of the gap junction structure, its functions and the family of the "connexin" genes, has been basically ignored by the major biological disciplines. These connexin genes code for proteins that organize to form membrane-associated hemi-channels, "connexons", co-join with the connexons of neighboring cells to form gap junctions. Gap junctions appeared in the early evolution of the metazoan. Their fundamental functions, (e.g., to synchronize electrotonic and metabolic functions of societies of cells, and to regulate cell proliferation, cell differentiation, and apoptosis), were accomplished via integrating the extra-cellular triggering of intra-cellular signaling, and therefore, regulating gene expression. These functions have been documented by genetic mutations of the connexin genes and by chemical modulation of gap junctions. Via genetic alteration of connexins in knock-out and transgenic mice, as well as inherited connexin mutations in various human syndromes, the gap junction has been shown to be directly linked to many normal cell functions and multiple diseases, such as birth defects, reproductive, neurological disorders, immune dysfunction and cancer. Specifically, the modulation of gap junctional intercellular communication (GJIC), either by increasing or decreasing its functions by non-mutagenic chemicals or by oncogenes or tumor suppressor genes in normal or "initiated" stem cells and their progenitor cells, can have a major impact on tumor promotion or cancer chemoprevention and chemotherapy. The overview of the roles of the gap junction in the evolution of the metazoan and its potential in understanding a "systems" view of human health and aging and the diseases of aging will be attempted.

Abstract
Faced with the reality of our current methods of drug discovery and toxicity assessment of all chemicals is less than perfect, the Report, ‘‘Toxicity Testing in the 21 st Century: A Vision and a Strategy’’, posed a reality check on all scientific efforts to find new conceptual and technical approaches for being better predictors of potential human health effects. This Commentary is a challenge to both the current paradigms and techniques to test chemicals for their potential toxicities. While, clearly, our scientific understanding of the mechanisms of chemical-induced toxicity and of the pathogeneses of all human diseases are not complete, the state of scientific understanding seems not only sufficient to know what we are now doing is not sufficient, but that it is adequate enough to make a new paradigm and technological change. Basically, the challenge includes the opinion that human exposure to chemicals, that are associated with one or more health endpoints (birth defects, cardiovascular diseases, cancer, reproductive and neurological dysfunctions), is the result of epigenetic , not mutagenic or genotoxic, mechanisms. In addition, it is postulated that the adult human stem cell should be considered the ‘‘target’’ cell for the important chemical-induced health effects. To test this hypothesis that altering the quantity and quality of adult stem cells by chemical exposures during in utero, neonatal, adolescent, adult and geriatric phases of life can lead to health consequences, it is recommended that 3-D in vitro cultures be used on male and female human adult stem cells from a few major organs (e.g., heart, brain, liver, lung, kidney, breast, prostate ). Altered stem cell biology (e.g., increase or decrease in the stem cell numbers in specific organs; altered apoptotic and differentiation frequencies), as well as measured cell-cell communication, should be seriously considered as toxicity endpoints.

Abstract
OBJECTIVE Treatment options for recurrent squamous cell carcinoma of the head and neck (SCCHN) following platinum-based therapy are limited. Lonafarnib is a potent, specific inhibitor of farnesyl transferase that demonstrated marked antitumor activity as monotherapy in treatment-naive SCCHN in a phase Ib study. A phase II study of lonafarnib was conducted to determine its efficacy and safety in patients with recurrent, platinum-refractory SCCHN. METHODS This was an open-label, phase II, single-center study in patients with recurrent SCCHN after platinum-based therapy. A Simon 2-stage design was used, with a plan to close the study to further accrual if <2 of the first 15 patients had objective responses. Patients were treated with lonafarnib 200 mg twice daily (b.i.d.) by mouth continuously in 4-week cycles. RESULTS Fifteen patients with baseline Eastern Cooperative Oncology Group PS 0-1 and median age 57 years were enrolled. Twelve patients had received at least 2 previous chemotherapy regimens. Median duration of treatment with lonafarnib was 61 days. No objective response was observed. Seven (47%) patients maintained stable disease through >or=3 cycles of therapy. Median time to progression and survival time were 2.04 and 9.17 months, respectively. Most treatment-related toxicities were grade 1-2, and there were no treatment-related deaths. CONCLUSIONS Lonafarnib at a dose of 200 mg b.i.d. was well-tolerated. However, there were no objective responses observed in the first 15 patients enrolled in this study, and the study was closed to further accrual, as per predefined criteria. Further evaluation of lonafarnib in platinum-refractory SCCHN is not planned.

Abstract
Concomitant chemoradiotherapy is a common treatment for advanced head and neck squamous cell carcinomas (HNSCC). Cisplatin is the backbone of chemotherapy regimens used to treat HNSCC. Therefore, the aim of this study was to identify predictive markers for cisplatin treatment outcome in HNSCC. The intrinsic cisplatin sensitivity (ICS) was determined in a panel of tumour cell lines. From this panel, one sensitive and two resistant cell lines were selected for comparative transcript profiling using microarray analysis. The enrichment of Gene Ontology (GO) categories in sensitive versus resistant cell lines were assessed using the Gene Ontology Tree Machine bioinformatics tool. In total, 781 transcripts were found to be differentially expressed and 11 GO categories were enriched. Transcripts contributing to this enrichment were further analyzed using Ingenuity Pathway Analysis (IPA) for identification of key regulator genes. IPA recognized 20 key regulator genes of which five were differentially expressed in sensitive versus resistant cell lines. The mRNA level of these five genes was further assessed in a panel of 25 HNSCC cell lines using quantitative real-time PCR. Among these key regulators, MMP-7 and MMP-13 are implicated as potential biomarkers of ICS. Taken together, genome-wide transcriptional analysis identified single genes, GO categories as well as molecular networks that are differentially expressed in HNSCC cell lines with different ICS. Furthermore, two novel predictive biomarkers for cisplatin resistance, MMP-7 and MMP-13, were identified.

Abstract
Tumor antiangiogenesis therapy has been in application for more than 30 years; however, its mechanism remains obscure. An intriguing hypothesis, which has recently gained acceptance, explores the possibility that antiangiogenesis therapy may transiently normalize tumor vasculature and its microenvironment, thus enhancing chemoradiotherapy efficacy. As the equilibrium between proangiogenesis and antiangiogenesis factors is perturbed in the tumor and tips to the former, tumor vasculature tends to exhibit abnormal structure and function. Abnormal vasculature is tightly associated with an uncharacteristic microenvironment, including uneven perfusion, hypoxia, and increased interstitial fluid pressure: This malignant microenvironment hinders the delivery of chemotherapeutics to tumor cells and desensitizes the malignant cells to radiation. Antiangiogenesis therapy can reverse the imbalance and transiently normalize this microenvironment and gives a new perspective for combining antiangiogenesis therapy and traditional chemoradiotherapy.

Abstract
PURPOSE Carcinoid and islet cell tumors are known to be highly vascular. There is no effective systemic therapy currently available for metastatic disease. We conducted a phase II trial to evaluate the efficacy of the anti-antiangiogenic agent thalidomide in metastatic neuroendocrine tumors. PATIENTS AND METHODS Eighteen patients with measurable, histologically proven metastatic carcinoid neuroendocrine carcinomas (well-differentiated, n = 13; moderately-differentiated, n = 5) were enrolled on this study. The majority of the patients had gastrointestinal primaries (small bowel, 8; pancreas, 5; colon, 1). All but one patient had hepatic metastases, and 12 patients (67%) had carcinoid syndrome. All patients had Eastern Cooperative Oncology Group performance status of zero or one. Eight patients (44%) had received previous hepatic artery chemoembolization and 11 (61%) had undergone surgical resection. Patients were started on oral thalidomide at a daily dose of 200 mg that was escalated to the target dose of 400 mg daily after 2 weeks. Tumor response was assessed at 12-week intervals using RECIST criteria. Planned treatment duration was 24 weeks unless unacceptable toxicity or disease progression was observed. RESULTS No patient achieved a partial remission or a complete remission. Best response was stable disease (SD) in 11 of 16 response-evaluable patients (69%). Serum pancreastatin results did not correlate with clinical response. Grade 3 toxicities included dizziness with orthostatic hypotension (n = 5), sensory neuropathy (n = 2), fatigue (n = 2), hemorrhagic cystitis (n = 1), and deep venous thrombosis (n = 1). Frequent Grade 1-2 toxicities were: fatigue (n = 13), constipation (n = 13), dry mouth (n = 12), somnolence (n = 12), dizziness/syncope (n = 10), weight gain (n = 5), and peripheral neuropathy (n = 5). CONCLUSIONS Thalidomide was fairly well tolerated in patients with metastatic carcinoid/islet cell tumors, but failed to reveal any objective responses. The single stage design of the trial makes it difficult to determine whether observed SD in a subset of patients was attributable to the indolent nature of these tumors, or to beneficial effect of thalidomide.

Abstract
Thalidomide is an immunomodulatory, antiangiogenic drug. Although there is evidence that it might be more effective in combination with chemotherapy the exact mechanism of action is unclear. Therefore, we investigated its effect in combination with metronomically applied cisplatin in a xenotransplant mouse model characteristic for advanced head and neck squamous cell carcinomas, its possible synergistic action in vitro, and which tumor-derived factors might be targeted by thalidomide. Although thalidomide alone was ineffective, a combined treatment with low-dose cisplatin inhibited significant tumor growth, proliferation and angiogenesis in vivo as well as migration and tube formation of endothelial cells in vitro. Noteworthy, the latter effect was enhanced after coapplication of cisplatin in nontoxic doses. An inhibitory effect on tumor cell migration was also observed suggesting a direct antitumor effect. Although thalidomide alone did not influence cell proliferation, it augmented antiproliferative response after cisplatin application emphasizing the idea of a potentiated effect when both drugs are combined. Furthermore, we could show that antiangiogenic effects of thalidomide are related to tumor-cell derived factors including vascular endothelial growth factor, basic fibroblast growth factor, hepatocyte growth factor and Il-8 some known and with, granulocyte colony stimulating growth factor and granulocyte macrophage colony stimulating growth factor, some new target molecules of thalidomide. Altogether, our findings reveal new insights into thalidomide-mediated antitumor and antiangiogenic effects and its interaction with cytostatic drugs.

Abstract
Thalidomide is an anti-angiogenic agent currently used to treat patients with malignant cachexia or multiple myeloma. Lenalidomide (CC-5013) is an immunomodulatory thalidomide analogue licensed in the United States of America (USA) for the treatment of a subtype of myelodysplastic syndrome. This two-centre, open-label phase I study evaluated dose-limiting toxicities in 55 patients with malignant solid tumours refractory to standard chemotherapies. Lenalidomide capsules were consumed once daily for 12 weeks according to one of the following three schedules: (I) 25 mg daily for the first 7 d, the daily dose increased by 25 mg each week up to a maximum daily dose of 150 mg; (II) 25mg daily for 21 d followed by a 7-d rest period, the 4-week cycle repeated for 3 cycles; (III) 10 mg daily continuously. Twenty-six patients completed the study period. Two patients experienced a grade 3 hypersensitivity rash. Four patients in cohort I and 4 patients in cohort II suffered grade 3 or 4 neutropaenia. In 2 patients with predisposing medical factors, grade 3 cardiac dysrhythmia was recorded. Grade 1 neurotoxicity was detected in 6 patients. One complete and two partial radiological responses were measured by computed tomography scanning; 8 patients had stable disease after 12 weeks of treatment. Fifteen patients remained on treatment as named patients; 1 with metastatic melanoma remains in clinical remission 3.5 years from trial entry. This study indicates the tolerability and potential clinical efficacy of lenalidomide in patients with advanced solid tumours who have previously received multi-modality treatment. Depending on the extent of myelosuppressive pre-treatment, dose schedules (II) or (III) are advocated for large-scale trials of long-term administration.

Abstract
PURPOSE To evaluate the dose-limiting toxicities (DLT), maximum tolerated dose (MTD), and pharmacokinetics of thalidomide in patients with advanced hepatocellular carcinoma (HCC). METHODS Patients with advanced HCC who were not feasible for definitive local therapy were eligible. Patients were enrolled in a cohort of three to receive thalidomide twice daily for 1 week to determine the MTD. Intra-patient dose escalation was permitted. Pharmacokinetic studies were performed at the first dose level and repeated at the second dose level of each patient. RESULTS Fifteen patients were accrued at four dose levels with the starting dose range 100-400 mg/day. Two patients at 400 mg/day experienced DLT (grade 3 angioedema and dyspnea, respectively). The MTD of twice-daily schedule was determined as 300 mg/day. The mean steady-state maximal blood concentration and mean steady-state area under the curve had a trend toward positive correlation, but non-linear proportionate, to the daily dose of thalidomide. Pharmacokinetic parameters are comparable for patients of Child-Pugh's A and B. Apparent mild, transient drug-induced transaminitis was early onset, self-limited, which occurred in 30.7% of patients. Serum hepatitis B or C viral titers was largely not affected. CONCLUSION The absorption and elimination of thalidomide are not significantly different in HCC patients with compensated or decompensated hepatic dysfunction.

Abstract
Angiogenesis is a multistep, complex and tightly regulated process that is necessary for tumor growth and metastasis. Based on data of preclinical models, several antiangiogenic compounds has been shown to modify activated tumor endothelium, which suggests that these compounds can improve cytotoxic drug delivery. Such agents have entered clinical trials as single agents or in combination with cytotoxic drugs, and have shown promising antitumor activity. The pharmacodynamic and pharmacokinetic characteristics of antiangiogenic drugs are reviewed here. Most of the early clinical testing of these agents was conducted in patients with advanced disease resistant to standard therapies. Phase III trials compared the efficacy of standard chemotherapy alone with standard chemotherapy in combination with an experimental angiogenesis inhibitor. Although some of these studies were negative or controversial, recent studies validated in large clinical trials with an anti-vascular endothelial growth factor antibody demonstrated significant clinical benefit and renewed enthusiasm for this therapeutic strategy. This review describes the clinical studies of antiangiogenic agents and highlights the challenges related to choosing appropriate strategies for the selection of patients, study design and choice of appropriate endpoints for the studies' development.

Abstract
BACKGROUND AND AIMS Thalidomide has undergone resurgence in the treatment of specific malignancies. One of the possible actions of thalidomide may be an antiangiogenic effect. This study investigates the effects of thalidomide on tumor growth and long-term survival in a murine model of colorectal liver metastases. METHODS Liver metastases were produced in male CBA mice by intrasplenic injection of a dimethyl hydrazine induced MoCR colon cancer murine cell line. Thalidomide was administered daily at doses ranging from 50 to 300 mg/kg by intraperitoneal injection. Tumor growth was assessed using quantitative stereological analysis. The effect on long-term survival was determined at the maximum tolerated dose using Kaplan-Meier analysis. The microvascular effects of thalidomide were assessed by laser Doppler flowmetry (LDF) and microvascular resin casting. Immunohistochemistry was used to determine vascular endothelial growth factor (VGEF) and basic fibroblast growth factor (bFGF) expression. RESULTS Thalidomide, (50-300 mg/kg) caused no significant reduction in tumor growth by day 21 following induction of liver metastases and caused systemic toxicity at a dose of 300 mg/kg. At a dose of 200 mg/kg given beyond 35 days, thalidomide significantly reduced tumor growth compared to control, (P = 0.029). No significant impact on survival was however observed (P = 0.93). LDF and microvascular resin casting showed no differences in blood flow or tumor microvascular architecture. VGEF and FGF were expressed in tumors, but remained unaltered by thalidomide administration compared to matched controls. CONCLUSIONS Thalidomide caused a significant reduction in the volume of colorectal liver metastases during the late phase of tumor growth. There was however no improvement in survival. Tumor growth reduction in this model did not appear to be due to microvascular changes or altered expression of VGEF or basic FGF. Further investigation into potential mechanisms of action of thalidomide and its synergistic use with other therapies is required.

Abstract
Functional properties of tumour vasculature influence the process of metastasis and play a role in generating a heterogeneous metabolic microenvironment, which contributes to genetic instability and inefficiency of tumour therapies. Morphological and functional properties of tumour vasculature may vary from tumour onset to late-stage disease. The aim of this study was to identify the dynamic alteration in tumour microcirculation in a chronic observation model. Invasively-growing, non-disseminating, green fluorescent protein transfected, human bone marrow derived endothelial cells, were implanted into cranial windows of severe combined immunodeficient mice. Intravital fluorescence microscopy was performed over a period of 85 days to measure permeability, leucocyte-endothelial interaction (LEI) and tissue perfusion rate as functional parameters. Vessel density, branching pattern and scanning electron microscopy were monitored as morphological parameters. Concordant with an increasing count of transendothelial pores, the results show that the initial event following tumour cell implantation was a significant increase in the permeability of pre-existing vessels. The variations in newly formed vessels were characterised by sequentially-occurring functional and morphological alterations with the development of characteristics typical of tumour vessels, such as increased count of trifurcations and variation in vessel calibre by more than 100%. In parallel with the increasing vessel volume per area, the tissue perfusion rate increased until day 61. It is concluded from the step-specific sequential functional and morphological alterations that the efficiency of adjuvant therapies depends not only on their intrinsic efficiency but also on the timing of their initiation.

Abstract
Thalidomide has antiangiogenic and immunomodulatory properties and has recently been used in the management of human malignancies. Multiple studies have confirmed its activity in multiple myeloma, alone or combined with dexamethasone and/or chemotherapy as first- or second-line treatment. In addition, it may reduce the need for transfusions in patients with myelofibrosis or myelodysplastic syndromes. The activity of thalidomide in solid tumours is less prominent. The most promising results have been reported in Kaposi's sarcoma, malignant melanoma and prostate cancer, especially when it is combined with chemotherapy. Recently, thalidomide analogues (immunomodulatory drugs), with higher immunomodulatory activity and different toxicity profile, have been developed. They have already shown promising activity in multiple myeloma and are currently being evaluated in clinical studies.

Abstract
Angiogenesis is necessary for tumor growth. Drug discovery efforts have identified several potential therapeutic targets on endothelial cells and selective inhibitors capable of slowing tumor growth or producing tumor regression by blocking angiogenesis in in vivo tumor models. Certain antiangiogenic therapeutics increase the activity of cytotoxic anticancer treatments in preclinical models. More than 75 antiangiogenic compounds have entered clinical trials. Most of the early clinical testing was conducted in patients with advanced disease resistant to standard therapies. Several phase III trials have been undertaken to compare the efficacy of standard chemotherapy versus the same in combination with an experimental angiogenesis inhibitor. Preliminary results of the clinical studies suggest that single-agent antiangiogenic therapy is poorly active in advanced tumors. Although some of the results of combination trials are controversial, recent positive outcomes with an antivascular endothelial growth factor antibody combined with chemotherapy as front-line therapy of metastatic colorectal cancer have renewed enthusiasm for this therapeutic strategy. This article presents an overview of experimental and clinical studies of combined therapy with antiangiogenic agents and highlights the challenges related to the appropriate strategies for selection of the patients, study design, and choice of proper end points for preclinical and clinical studies using these agents.

Abstract
AIM: To investigate the effects of thalidomide on angiogenesis, tumor growth and metastasis of hepatocellular carcinoma in nude mice.
METHODS: Twenty-four nude mice were randomly divided into therapy group and control group, 12 mice in each group. Thalidomide dissolved in 0.5% sodium carboxyl methyl cellulose (CMC) suspension was administered intraperitoneally once a day at the dose of 200 mg/kg in therapy group, and an equivalent volume of 0.5% CMC in control group. Mice were sacrificed on the 30th d, tumor size and weight and metastases in liver and lungs were measured. CD34 and VEGF mRNA in tumor tissue were detected by immunohistochemistry and semi-quantitative RT-PCR respectively and microvessel density (MVD) was counted. Serum concentrations of TNF-α and ALT and AFP were also tested.
RESULTS: MVD and VEGF mRNA in therapy group were less than those in control group (31.08±16.23 vessels/HP vs 80.00±26.27 vessels/HP, 0.0538±0.0165 vs 0.7373±0.1297, respectively, P<0.05). No statistical difference was observed in tumor size and weight and metastases in liver and lungs. TNF-α was significantly lower in therapy group than in control group (28.64±4.64 ng/L vs 42.69±6.99 ng/L, P<0.05). No statistical difference in ALT and AFP was observed between groups.
CONCLUSION: Thalidomide can significantly inhibit angiogenesis and metastasis of hepatocellular carcinoma. It also has inhibitory effects on circulating TNF-α.

Abstract
Following reports of its teratogenicity, thalidomide was banned from the market in the 1960s. Later, the elucidation that the inhibition of angiogenesis underlies this teratogenicity and the recognition of the importance of angiogenesis in malignancies has raised interest in thalidomide as an anti-tumour agent. Since then, numerous other mechanisms accounting for the anti-tumour effect of thalidomide have been revealed and many studies exploring the efficacy of thalidomide in tumours have been initiated. This Review focuses on the application of thalidomide and its derivatives in solid tumours, the mechanisms underlying their anti-tumour effects, and their potential to be applied in combination with other anti-tumour agents.

Abstract
PURPOSE Tumor growth and metastasis is believed to depend on the tumor's ability to induce neovascularization. Recent studies have indicated that thalidomide inhibits angiogenesis. We performed a phase I and pharmacokinetic study of thalidomide with carboplatin in children with refractory solid tumors. PATIENTS AND METHODS Carboplatin was administered as a single intravenous dose once every 21 days at a target area under the concentration-time curve of 6 mg/mL.min. Thalidomide was administered daily by mouth. The initial dose level was 100 mg/m(2)/d with intrapatient dose escalation to a maximum dose of 300 mg/m(2)/d. The next cohort of patients started at a dose of 300 mg/m(2)/d, with intrapatient dose escalation to a maximum dose of 500 mg/m(2)/d. Standard response and adverse event criteria were used. Serial blood samples for thalidomide pharmacokinetics studies were obtained after the first dose. RESULTS Twenty-two patients received 56 cycles of therapy. The maximum tolerated thalidomide dose was 400 mg/m(2)/d. The dose-limiting toxicity was somnolence. There were no objective responses. Thalidomide's apparent clearance was 55 +/- 16 mL/min/m(2) and the terminal half-life was 5.9 +/- 2.8 hours. There was no evidence of dose-dependent pharmacokinetics in the narrow range studied. CONCLUSION Thalidomide at a dose of 400 mg/m(2)/d can be safely administered to children with solid tumors in combination with carboplatin. Somnolence is the major toxicity. In addition, we have characterized the pharmacokinetic behavior of thalidomide in children. This study can serve as the basis for future investigation of thalidomide as an anticancer agent in children.

Abstract
Thalidomide, an oral agent with antiangiogenic and immunomodulatory properties, is being investigated extensively in the management of advanced cancer. Multiple studies with large numbers of patients have confirmed that this drug has significant activity in multiple myeloma. Some patients with myelofibrosis or myeodysplatic syndromes may reduce their need for transfusions after thalidomide treatment. The activity of thalidomide in solid tumors is less prominent. Studies in Kaposi's sarcoma, malignant melanoma, renal cell carcinoma and prostate cancer appear more promising especially when thalidomide is combined with biological agents or with chemotherapy. Limited activity was demonstrated in patients with glioma, while thalidomide appears to be inactive in patients with head and neck cancer, breast or ovarian cancer.

Abstract
We present the case of a 33-year-old man with isolated splenic peliosis, a rare pathological condition characterized by blood filled cystic lesions. The patient presented with recurrent massive haemorrhagic ascites, which did not resolve, despite a splenectomy. He was found to have massively elevated levels of vascular endothelial growth factor (VEGF). The clinical course of the disease was prolonged. Repeated blood transfusions for recurrent anaemia were required, in addition to repeated aspiration of reaccumulating haemorrhagic ascites and pleural effusion. The clinical course was not in keeping with previously reported cases. We have described an atypical clinical presentation in a patient with isolated splenic peliosis associated with elevated VEGF concentrations. No previously known associations for the condition were found despite thorough investigations. Management of the patient has been symptomatic and palliative. We have reviewed the various reported associations of peliosis and discussed the possible role of VEGF in this patient's condition.

Abstract
Despite its history as a human teratogen, thalidomide is emerging as a treatment for cancer and inflammatory diseases. Although the evolution of its clinical application could not have been predicted from the tragedy associated with its misuse in the past, its history serves as a lesson in drug development that underscores the need to understand the molecular pharmacology of a compound's activity, including associated toxicities. Here, we summarise the applications for thalidomide with an emphasis on clinical trials published over the past 10 years, and consider our knowledge of the molecular pharmacology of the drug in the context of clinical trial data, attempting to provide a mechanism-guided understanding of its activity.

Abstract
We assessed the safety, tolerability and efficacy of the immunomodulatory drug, CC-5013 (REVIMID™), in the treatment of patients with metastatic malignant melanoma and other advanced cancers. A total of 20 heavily pretreated patients received a dose-escalating regimen of oral CC-5013. Maximal tolerated dose, toxicity and clinical responses were evaluated and analysis of peripheral T-cell surface markers and serum for cytokines and proangiogenic factors were performed. CC-5013 was well tolerated. In all, 87% of adverse effects were classified as grade 1 or grade 2 according to Common Toxicity Criteria and there were no serious adverse events attributable to CC-5013 treatment. Six patients failed to complete the study, three because of disease progression, two withdrew consent and one was entered inappropriately and withdrawn from the study. The remaining 14 patients completed treatment without dose reduction, with one patient achieving partial remission. Evidence of T-cell activation was indicated by significantly increased serum levels of sIL-2 receptor, granulocyte–macrophage colony-stimulating factor, interleukin-12 (IL-12), tumour necrosis factor-α and IL-8 in nine patients from whom serum was available. However, levels of proangiogenic factors vascular endothelial growth factor and basic foetal growth factor were not consistently affected. This study demonstrates the safety, tolerability and suggests the clinical activity of CC-5013 in the treatment of refractory malignant melanoma. Furthermore, this is the first report demonstrating T-cell stimulatory activity of this class of compound in patients with advanced cancer.

Abstract
Growth factors are a large family of polypeptide molecules that regulate cell division in many tissues by autocrine or paracrine mechanisms. Depending on what receptors are activated, growth factors can initiate mitogenic, antiproliferative, or trophic effects, that is, growth factors act as positive or negative modulators of cell proliferation. Therefore, growth factors do not only play an important role in embryonic development and adult tissue homeostasis, but also in pathological situations like infection, wound healing, and tumorigenesis. Consequently, the application of growth factors, or vice versa the application of substances which are directed against growth factors like antigrowth factor antibodies, may have therapeutic applications. This review provides a brief account of what we know regarding growth factors in otorhinolaryngology, particularly in the field of otology, wound healing, oncology, peripheral nerve regeneration, and rhinology.

Abstract
AIM: To study the effect of TNP-470 on cell growth, proliferation and apoptosis in human colon cancer xenografts in nude mice.
METHODS: Human colon cancer xenografts were transplanted into 20 nude mice. Mice were randomly divided into two groups. TNP-470 treated group received TNP-470 (30 mg/kg, s.c) every other day and the control group received a sham injection of same volume saline solution. They were sacrificed after 4 wk and their tumors were processed for histological examination. The expression of proliferating cell nuclear antigen (PCNA) in tumors was detected using immunohistochemical method with image analysis, and apoptosis in tumor cells was measured by TdT-mediated biotinyated-dUTP nick end labeling (TUNEL) staining.
RESULTS: Comparing with controls, tumor growth was significantly inhibited in TNP-470 treated group, the inhibitory rate being 54.4%. Expression of PCNA in tumors of TNP-470 treated group (PI 54.32 ± 11.47) was significantly lower than that of control group (PI 88.54 ± 12.36), P < 0.01. Apoptosis index (AI) of TNP-470 treated group (18.95 ± 1.71) was significantly higher than that of control group (7.26 ± 1.44), P < 0.001, typical morphological change of apoptosis in tumor cells was observed in TNP-470 treated group.
CONCLUSION: Besides the anti-angiogenic effects, TNP-470 can inhibit tumor growth by inhibiting the proliferation and inducing apoptosis of tumor cells.

Abstract
BACKGROUND Thalidomide is best known as a major teratogen that caused birth defects in up to 12,000 children in the 1960s. More recently, this agent has been approved by the US Food and Drug Administration for the treatment of erythema nodosum leprosum (ENL) through a restricted-use program. Its immunomodulatory, anti-inflammatory, and antiangiogenic properties are currently under study in a number of clinical conditions. OBJECTIVE This article reviews the pharmacology of thalidomide; its approved and off-label uses in dermatologic, oncologic, and gastrointestinal conditions; and adverse events associated with its use. METHODS Relevant articles were identified through searches of MEDLINE (1966-June 2002), International Pharmaceutical Abstracts (1970-June 2002), and EMBASE (1990-June 2002). Search terms included but were not limited to thalidomide, pharmacokinetics, pharmacology, therapeutic use, and teratogenicity, as well as terms for specific disease states and adverse events. Further publications were identified from the reference lists of the reviewed articles. Abstracts of recent symposia were obtained from the American Society of Clinical Oncology Web site. RESULTS Thalidomide is thought to exert its therapeutic effect through the modulation of cytokines, particularly tumor necrosis factor-alpha. In addition to its approved indication for ENL, thalidomide has been studied in various other conditions, including graft-versus-host disease, discoid lupus erythematosus, sarcoidosis, relapsed/refractory multiple myeloma, Waldenstrom's macroglobulinemia, myelodysplastic syndromes, acute myeloid leukemia, myelofibrosis with myeloid metaplasia, renal cell carcinoma, malignant gliomas, prostate cancer, Kaposi's sarcoma, colorectal carcinoma, oral aphthous ulcers, Behçet's disease, Crohn's disease, and HIV/AIDS-associated wasting. Adverse events most frequently associated with its use include somnolence, constipation, rash, peripheral neuropathy, and thromboembolism. CONCLUSIONS Use of thalidomide is limited by toxicity, limited efficacy data, and restricted access. Evidence of its efficacy in conditions other than ENL awaits the results of controlled clinical trials.

Abstract
The demonstration of increased angiogenesis in cancer pathogenesis prompted the use of thalidomide in both solid tumors and hematologic malignancies. Its broad spectrum of actions besides its antiangiogenic potential, specifically, its immunomodulatory properties, antiinflammatory actions, and direct effect on tumor cells and their microenvironment, provides an alternative strategy in the armamentarium against cancer. Thalidomide is being evaluated for treatment of hematologic cancers like multiple myeloma and myelodysplasia, and solid tumors like lung, breast, renal, and colon cancer. Thalidomide analogues, the immunomodulatory drugs have increased potency and have demonstrated efficacy and reduced toxicity in phase I and II clinical studies. This article reviews both laboratory-based and clinical studies with thalidomide and the immunomodulatory drugs and their application in different cancers.

Abstract
Lung cancer is a major public health problem and the leading cause of cancer-related death worldwide. Its survival rates have changed little over the past 20 years. The best clinical benefit (ie, survival rates) with combination cytotoxic therapies in non-small-cell lung cancer (NSCLC) may have been reached. The need for improved survival rates in NSCLC has driven the development of novel, rationally designed, targeted therapies. Inhibitors of angiogenesis have been developed and are increasingly studied. Potential targets for therapy include inhibitors of vascular endothelial growth factor receptor, endogenous angiogenesis inhibitors, and cyclooxygenase inhibitors. Combining targeted molecules with traditional cytotoxic therapies usually results in lower required chemotherapy doses and fewer, less severe side effects. A number of ongoing randomized studies are underway to evaluate this idea. It is anticipated that these new targeted therapies will play an important role, along with cytotoxic and radiation therapies, in the management of metastatic disease.
