多药耐药(MDR)的形成是胃癌难治与复发的生物学基础,寻找肿瘤耐药的形成机制及有效的逆转药物是肿瘤研究领域的一项重要课题。

近十余年来,人们发现以阿斯匹林为代表的非甾体类消炎药(NsAⅢs)在肿瘤,尤其是消化道肿瘤的预防与治疗中具有明显的作用,其机制可能与抑制环氧合酶-2(COX-2)合成有关。

环氧合酶(coxl是前列腺素类合成的限速酶,已有多项研究证实其亚型COX.2通过多种途径参与消化道肿瘤的形成。

目前发现COX一2还可能与肿瘤多药耐药有关,从而进一步丰富了COX-2与肿瘤相关的证据,为肿瘤的防治开辟了一条崭新途径。

ENKTL原发部位常见于鼻、鼻咽、口咽、韦氏环等,少数可侵犯皮肤、胃肠道、睾丸、骨髓等结外组织,临床表现多为鼻塞、鼻出血、声嘶、鼻咽部肿物等,可在鼻腔底部形成特征性硬腭穿孔,伴有恶臭。

ENKTL为高度侵袭性恶性肿瘤,进展快、易复发转移,尚无标准治疗方案,预后不良。

体重指数(body mass index,BMI)被认为与肿瘤的预后密切相关,在乳腺癌,肾癌,胆囊癌,食管癌等都有报道显示BMI 与其预后存在相关性。

Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have completeinformation requisite for the follow-up of the patient. [See Warnings and Precautions (5.1)]• Increased susceptibility to infection and the possible development of malignancies such as lymphoma and skin cancer may result from immunosuppression. [See Warnings and Precautions (5.2 and 5.3)]Kidney Graft Thrombosis• An increased risk of kidney arterial and venous thrombosis, resulting in graft loss, was reported, mostly within the first 30 days post-transplantation. [See Warnings and Precautions (5.4)]Nephrotoxicity• Increased nephrotoxicity can occur with use of standard doses of cyclosporine in combination with Zortress.Therefore reduced doses of cyclosporine should be used in combination with Zortress in order to reduce renaldysfunction. It is important to monitor the cyclosporine and everolimus whole blood trough concentrations. [See Dosage and Administration (2.4 and 2.5) and Warnings and Precautions (5.6) and Clinical Pharmacology (12.7 and12.8)]Mortality in Heart Transplantation• Increased mortality, often associated with serious infections, within the first three months post-transplantation was observed in a clinical trial of de novo heart transplant patients receiving immunosuppressive regimens with or without induction therapy. Use in heart transplantation is not recommended. [See Warnings and Precautions (5.7)]1 INDICATIONS AND USAGE1.1 Prophylaxis of Organ Rejection in Kidney TransplantationZortress is indicated for the prophylaxis of organ rejection in adult patients at low-moderate immunologic risk receiving a kidney transplant. [See Clinical Studies (14.1)] Zortress is to be administered in combination with basiliximab induction and concurrently with reduced doses of cyclosporine and with corticosteroids. Therapeutic drug monitoring of everolimus and cyclosporine is recommended for all patients receiving these products. [See Dosage and Administration (2.2 and 2.3)] 1.2 Prophylaxis of Organ Rejection in Liver TransplantationZortress is indicated for the prophylaxis of allograft rejection in adult patients receiving a liver transplant. Zortress is to be administered no earlier than 30 days post-transplant concurrently in combination with reduced doses of tacrolimus and with corticosteroids [See Warnings and Precautions (5.5) and Clinical Studies (14.2)]. Therapeutic drug monitoring of everolimus and tacrolimus is recommended for all patients receiving these products. [See Dosage and Administration (2.3 and 2.5)]1.3 Limitations of UseThe safety and efficacy of Zortress has not been established in the following populations:Kidney transplant patients at high immunologic riskRecipients of transplanted organs other than kidney and liver [See Warnings and Precautions (5.7)]Pediatric patients (<18 years).2 DOSAGE AND ADMINISTRATIONPatients receiving Zortress may require dose adjustments based on everolimus blood concentrations achieved, tolerability, individual response, change in concomitant medications and the clinical situation. Optimally, dose adjustments of Zortress should be based on trough concentrations obtained 4 or 5 days after a previous dosing change. Dose adjustment is required if the trough concentration is below 3 ng/mL. The total daily dose of Zortress should be doubled using the available tablet strengths (0.25 mg, 0.5 mg or 0.75 mg). Dose adjustment is also required if the trough concentration is >8ng/mL on 2 consecutive measures; the dose of Zortress® should be decreased by 0.25 mg b.i.d. [See Therapeutic Drug Monitoring (2.3) and Clinical Pharmacology (12.3)]2.1 Dosage in Adult Kidney Transplant PatientsAn initial Zortress dose of 0.75 mg orally twice daily (1.5 mg per day) is recommended for adult kidney transplant patients in combination with reduced dose cyclosporine, administered as soon as possible after transplantation. [See Therapeutic Drug Monitoring (2.3, 2.4), Clinical Studies (14.1)]Oral prednisone should be initiated once oral medication is tolerated. Steroid doses may be further tapered on an individualized basis depending on the clinical status of patient and function of graft.2.2 Dosage in Adult Liver Transplant PatientsStart Zortress at least 30 days post-transplant. An initial dose of 1.0 mg orally twice daily (2.0 mg per day) is recommended for adult liver transplant patients in combination with reduced dose tacrolimus. [See Therapeutic Drug Monitoring (2.3 and 2.5), Clinical Studies (14.2)]Steroid doses may be further tapered on an individualized basis depending on the clinical status of patient and function of graft.2.3 Therapeutic Drug Monitoring -EverolimusRoutine everolimus whole blood therapeutic drug concentration monitoring is recommended for all patients. The recommended everolimus therapeutic range is 3 to 8 ng/mL. [See Clinical Pharmacology (12.7)] Careful attention should be made to clinical signs and symptoms, tissue biopsies, and laboratory parameters. It is important to monitor everolimus blood concentrations, in patients with hepatic impairment, during concomitant administration of CYP3A4 inducers or inhibitors, when switching cyclosporine formulations and/or when cyclosporine dosing is reduced according to recommended target concentrations. [See Clinical Pharmacology (12.7, 12.8)]There is an interaction of cyclosporine on everolimus, and consequently, everolimus concentrations may decrease if cyclosporine exposure is reduced. There is little to no pharmacokinetic interaction of tacrolimus on everolimus, and thus, everolimus concentrations do not decrease if the tacrolimus exposure is reduced. [See Drug Interactions (7.2)]The everolimus recommended therapeutic range of 3 to 8 ng/mL is based on an LC/MS/MS assay method. Currently in clinical practice, everolimus whole blood trough concentrations may be measured by chromatographic or immunoassay methodologies. Because the measured everolimus whole blood trough concentrations depend on the assay used, individual patient sample concentration values from different assays may not be interchangeable. Consideration of assay results must be made with knowledge of the specific assay used. Therefore, communication should be maintained with the laboratory performing the assay.2.4 Therapeutic Drug Monitoring-Cyclosporine in Kidney Transplant PatientsBoth cyclosporine doses and the target range for whole blood trough concentrations should be reduced, when given in a regimen with Zortress, in order to minimize the risk of nephrotoxicity. [See Warnings and Precautions (5.6), Drug Interactions (7.2), Clinical Pharmacology (12.8)]The recommended cyclosporine therapeutic ranges when administered with Zortress are 100 to 200 ng/mL through Month 1 post-transplant, 75 to 150 ng/mL at Months 2 and 3 post-transplant, 50 to 100 ng/mL at Month 4 post-transplant, and 25 to 50 ng/mL from Month 6 through Month 12 post-transplant. The median trough concentrations observed in the clinical trial ranged between 161 to 185 ng/mL through Month 1 post-transplant and between 111 to 140 ng/mL at Months 2 and 3 post-transplant. The median trough concentration was 99 ng/mL at Month 4 post-transplant and ranged between 46 to 75 ng/mL from Months 6 through Month 12 post-transplant. [See Clinical Pharmacology (12.8) and Clinical Studies (14.1)] Cyclosporine, USP Modified is to be administered as oral capsules twice daily unless cyclosporine oral solution or intravenous administration of cyclosporine cannot be avoided. Cyclosporine, USP Modified should be initiated as soon as possible -and no later than 48 hours -after reperfusion of the graft and dose adjusted to target concentrations from Day 5 onwards.If impairment of renal function is progressive the treatment regimen should be adjusted. In renal transplant patients, the cyclosporine dose should be based on cyclosporine whole blood trough concentrations. [See Clinical Pharmacology (12.8)]In renal transplantation, there are limited data regarding dosing Zortress with reduced cyclosporine trough concentrations of 25 to 50 ng/mL after 12 months. Zortress has not been evaluated in clinical trials with other formulations ofcyclosporine. Prior to dose reduction of cyclosporine it should be ascertained that steady-state everolimus whole blood trough concentration is at least 3 ng/mL. There is an interaction of cyclosporine on everolimus, and consequently, everolimus concentrations may decrease if cyclosporine exposure is reduced. [See Drug Interactions (7.2)]2.5 Therapeutic Drug Monitoring-Tacrolimus in Liver Transplant PatientsBoth tacrolimus doses and the target range for whole blood trough concentrations should be reduced, when given in a regimen with Zortress, in order to minimize the potential risk of nephrotoxicity. [See Warnings and Precautions (5.6), Clinical Pharmacology (12.9)]The recommended tacrolimus therapeutic range when administered with Zortress are whole blood trough (C-0h) concentrations of 3 to 5 ng/mL by three weeks after the first dose of Zortress (approximately Month 2) and through Month 12 post transplant.The median tacrolimus trough concentrations observed in the clinical trial ranged between 8.6 to 9.5 ng/mL at Weeks 2 and 4 post-transplant (prior to initiation of everolimus). The median tacrolimus trough concentrations ranged between 7 to 8.1 ng/mL at Weeks 5 and 6 post-transplant, between 5.2 to 5.6 ng/mL at Months 2 and 3 post-transplant, and between 4.3 to 4.9 ng/mL between Months 4 and 12 post-transplant. [See Clinical Pharmacology (12.9), Clinical Studies (14.2)] Tacrolimus is to be administered as oral capsules twice daily unless intravenous administration of tacrolimus cannot be avoided.In liver transplant patients, the tacrolimus dose should be based on tacrolimus whole blood trough concentrations. [See Clinical Pharmacology (12.9)]In liver transplantation, there are limited data regarding dosing Zortress with reduced tacrolimus trough concentrations of 3 to 5 ng/mL after 12 months. Prior to dose reduction of tacrolimus it should be ascertained that the steady-state everolimus whole blood trough concentration is at least 3 ng/mL. Unlike the interaction between cyclosporine and everolimus, tacrolimus does not affect everolimus trough concentrations, and consequently, everolimus concentrations do not decrease if the tacrolimus exposure is reduced.2.6 AdministrationZortress tablets should be swallowed whole with a glass of water and not crushed before use.Administer Zortress consistently approximately 12 hours apart with or without food to minimize variability in absorption and at the same time as cyclosporine or tacrolimus. [See Clinical Pharmacology (12.3)]2.7 Hepatic ImpairmentWhole blood trough concentrations of everolimus should be closely monitored in patients with impaired hepatic function. For patients with mild hepatic impairment (Child-Pugh Class A), the initial daily dose should be reduced by approximately one-third of the normally recommended daily dose. For patients with moderate or severe hepatic impairment (Child-Pugh B or C), the initial daily dose should be reduced to approximately one-half of the normally recommended daily dose. Further dose adjustment and/or dose titration should be made if a patient’s whole blood trough concentration of everolimus, as measured by an LC/MS/MS assay, is not within the target trough concentration range of 3 to 8 ng/mL. [See Clinical Pharmacology (12.6)]3 DOSAGE FORMS AND STRENGTHSZortress is available as 0.25 mg, 0.5 mg, and 0.75 mg tablets.Table 1. Description of Zortress (everolimus) TabletsDosage Strength 0.25 mg 0.5 mg 0.75 mg Appearance White to yellowish, marbled, round, flat tablets with bevelled edgeImprint “C” on one side and “NVR”on the other “CH” on one side and“NVR” on the other“CL” on one side and“NVR” on the other4 CONTRAINDICATIONS4.1 Hypersensitivity ReactionsZortress is contraindicated in patients with known hypersensitivity to everolimus, sirolimus, or to components of the drug product.5 WARNINGS AND PRECAUTIONS5.1 Management of ImmunosuppressionOnly physicians experienced in management of systemic immunosuppressant therapy in transplantation should prescribe Zortress. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for the maintenance therapy should have complete information requisite for the follow-up of the patient. In limited data with the complete elimination of CNI (calcineurin inhibition), there was an increased risk of acute rejection.5.2 Lymphomas and Other MalignanciesPatients receiving immunosuppressants, including Zortress, are at increased risk of developing lymphomas and other malignancies, particularly of the skin. The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent.As usual for patients with increased risk for skin cancer, exposure to sunlight and ultraviolet light should be limited by wearing protective clothing and using a sunscreen with a high protection factor.5.3 Serious InfectionsPatients receiving immunosuppressants, including Zortress, are at increased risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections. [See Warnings and Precautions (5.13), Adverse Reactions (6.1, 6.2)] These infections may lead to serious, including fatal, outcomes. Because of the danger of over immunosuppression, which can cause increased susceptibility to infection, combination immunosuppressant therapy should be used with caution.Antimicrobial prophylaxis for Pneumocystis jiroveci (carinii) pneumonia and prophylaxis for cytomegalovirus (CMV) is recommended in transplant recipients.5.4 Kidney Graft ThrombosisAn increased risk of kidney arterial and venous thrombosis, resulting in graft loss, has been reported, usually within the first 30 days post-transplantation. [See Boxed Warning]5.5 Hepatic Artery ThrombosisMammalian target of rapamycin (mTOR) inhibitors are associated with an increase in hepatic artery thrombosis (HAT). Reported cases mostly have occurred within the first 30 days post-transplant and most also lead to graft loss or death. Therefore, Zortress should not be administered earlier than 30 days after liver transplant.5.6 Zortress and Calcineurin Inhibitor-Induced NephrotoxicityIn kidney transplant recipients, Zortress with standard dose cyclosporine increases the risk of nephrotoxicity resulting in a lower glomerular filtration rate. Reduced doses of cyclosporine are required for use in combination with Zortress in order to reduce renal dysfunction. [See Boxed Warning, Indications and Usage (1.1), Clinical Pharmacology (12.8)]In liver transplant recipients, Zortress has not been studied with standard dose tacrolimus. Reduced doses of tacrolimus should be used in combination with Zortress in order to minimize the potential risk of nephrotoxicity. [See Indications and Usage (1.2), Clinical Pharmacology (12.9)]Renal function should be monitored during the administration of Zortress. Consider switching to other immunosuppressive therapies if renal function does not improve after dose adjustments or if the dysfunction is thought to be drug related. Caution should be exercised when using other drugs which are known to impair renal function.5.7 Heart TransplantationIn a clinical trial of de novo heart transplant patients, Zortress in an immunosuppressive regimen with or without induction therapy, resulted in an increased mortality often associated with serious infections within the first three months post-transplantation compared to the control regimen. Use of Zortress in heart transplantation is not recommended.5.8 AngioedemaZortress has been associated with the development of angioedema. The concomitant use of Zortress with other drugs known to cause angioedema, such as angiotensin converting enzyme (ACE) inhibitors may increase the risk of developing angioedema.5.9 Wound Healing and Fluid AccumulationZortress increases the risk of delayed wound healing and increases the occurrence of wound-related complications like wound dehiscence, wound infection, incisional hernia, lymphocele and seroma. These wound-related complications may require more surgical intervention. Generalized fluid accumulation, including peripheral edema (e.g., lymphoedema) and other types of localized fluid collection, such as pericardial and pleural effusions and ascites have also been reported.5.10 Interstitial Lung Disease/Non-Infectious PneumonitisA diagnosis of interstitial lung disease (ILD) should be considered in patients presenting with symptoms consistent with infectious pneumonia but not responding to antibiotic therapy and in whom infectious, neoplastic and other non-drug causes have been ruled-out through appropriate investigations. Cases of ILD, implying lung intraparenchymal inflammation (pneumonitis) and/or fibrosis of non-infectious etiology, some reported with pulmonary hypertension (including pulmonary arterial hypertension [PAH]) as a secondary event, have occurred in patients receiving rapamycins and their derivatives, including Zortress. Most cases generally resolve on drug interruption with or without glucocorticoid therapy. However, fatal cases have also occurred.5.11 HyperlipidemiaIncreased serum cholesterol and triglycerides, requiring the need for anti-lipid therapy, have been reported to occur following initiation of Zortress and the risk of hyperlipidemia is increased with higher everolimus whole blood trough concentrations. [See Adverse Reactions (6.2)] Use of anti-lipid therapy may not normalize lipid levels in patients receiving Zortress.Any patient who is administered Zortress should be monitored for hyperlipidemia. If detected, interventions, such as diet, exercise, and lipid-lowering agents should be initiated as outlined by the National Cholesterol Education Program guidelines. The risk/benefit should be considered in patients with established hyperlipidemia before initiating an immunosuppressive regimen containing Zortress. Similarly, the risk/benefit of continued Zortress therapy should be re­evaluated in patients with severe refractory hyperlipidemia. Zortress has not been studied in patients with baseline cholesterol levels >350 mg/dL.Due to an interaction with cyclosporine, clinical trials of Zortress and cyclosporine in kidney transplant patients strongly discouraged patients from receiving the HMG-CoA reductase inhibitors simvastatin and lovastatin. During Zortress therapy with cyclosporine, patients administered an HMG-CoA reductase inhibitor and/or fibrate should be monitored for the possible development of rhabdomyolysis and other adverse effects, as described in the respective labeling for these agents. [See Drug Interactions (7.7)]5.12 ProteinuriaThe use of Zortress in transplant patients has been associated with increased proteinuria. The risk of proteinuria increased with higher everolimus whole blood trough concentrations. Patients receiving Zortress should be monitored for proteinuria. [See Adverse Reactions (6.2)]5.13 Polyoma Virus InfectionsPatients receiving immunosuppressants, including Zortress, are at increased risk for opportunistic infections; including polyoma virus infections. Polyoma virus infections in transplant patients may have serious, and sometimes fatal, outcomes. These include polyoma virus-associated nephropathy (PVAN), mostly due to BK virus infection, and JC virus associated progressive multiple leukoencephalopathy (PML). PVAN has been observed in patients receiving immunosuppressants, including Zortress. PVAN is associated with serious outcomes; including deteriorating renal function and kidney graft loss. [See Adverse Reactions (6.2)] Patient monitoring may help detect patients at risk for PVAN. Reductions in immunosuppression should be considered for patients who develop evidence of PVAN or PML. Physicians should also consider the risk that reduced immunosuppression represents to the functioning allograft.5.14 Interaction with Strong Inhibitors and Inducers of CYP3A4Co-administration of Zortress with strong CYP3A4-inhibitors (e.g., ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, ritonavir, boceprevir, telaprevir) and strong CYP3A4 inducers (e.g., rifampin, rifabutin) is not recommended without close monitoring of everolimus whole blood trough concentrations.

Abstract: The tumor microenvironment is critical in the initiation and progression of cancerous growth, which is dependent on the establishment of a functional vascular network supporting neoplastic proliferation. While the precise role of tumor angiogenesis in lymphoma pathogenesis remains under active investigation, emerging data on the pro-angiogenic properties of the neoplastic lymphoma cells and mechanism of vascular assembly suggest that angiogenesis is highly relevant to the biology and therapy of non-Hodgkin’s lymphoma. Antiangiogenic therapies in non-Hodgkin’s lymphoma are in various stages of clinical development aiming at distinct angiogenic pathways operative in endothelial cells and perivascular stromal cells. The major classes of available antiangiogenics include anti-VEGF, small molecule inhibitors targeting proangiogenic receptor tyrosine kinases and their downstream signal transduction pathways, as well as immunomodulatory compounds with antiangiogenic properties. Preliminary clinical data indicate therapeutic advantages associated with strategies targeting dual compartments of vascular cells and tumor cells, as well as multiple angiogenic pathways within the tumor microenvironment. This review summarizes recent applications of antiangiogenic strategies in non-Hodgkin’s lymphoma based on current understanding of the biology of lymphoma angiogenesis.

Keywords: Angiogenesis, antiangiogenic therapy, microenvironment, non-Hodgkin’s lymphoma, VEGF.

INTRODUCTION Lymphoma is the second fastest growing adult malignancy in incidence in North America. In 2010, over 65,000 new cases of non-Hodgkin’s lymphoma (NHL) were diagnosed, and more than 20,000 people died from the diseases in the US [1]. Despite the fact that multi-modality treatment including combination chemotherapy, radiation, and target-specific monoclonal antibodies can induce a high-rate of remission in many subtypes of non-Hodgkin’s lymphoma, a significant proportion of patients relapse with incurable disease [2-3]. Novel therapeutic strategies are being actively explored to overcome treatment resistance. Amongst them, anti-angiogenics has emerged as a promising treatment modality that targets tumor microenvironment in complementary to tumor cell oriented therapy.

Angiogenesis, the growth of new blood vessels, requires dynamic expansion, assembly and stabilization of vascular endothelial cells in response to pro-angiogenic stimuli. Many aspects of tumor angiogenesis have been extensively studied in the context of nonhematopoietic neoplasms in the past three decades [4-5], and anti-angiogenic strategy has become an important treatment option for solid tumors in various clinical settings including metastatic colorectal, lung, breast, renal and liver cancers [6-10]. Non-Hodgkin’s lymphoma consists of a collection of complex disease subtypes driven by monoclonal proliferation of malignant B- or T-cells, which display a spectrum of clinical behaviors, ranging from indolent subtypes with growth latency measured in years to aggressive subtypes with progression measured in weeks to months [11]. The precise role of angiogenesis in the pathogenesis of lymphoproliferative disease is under active

investigation. Emerging evidence, analyzing both the angiogenic properties of the neoplastic cells as well as vascular microenvironment, suggests divergent angiogenic patterns in disparate lymphoma subtypes. To date, several lines of evidence have pointed to the relevance of angiogenesis to lymphoma progression and clinical outcome. First, increased production of proangiogenic growth factors by lymphoma tumor cells as well as infiltrating stromal cells, and increased angiogenesis activity (by vessel counts) has been observed with histological progression of the lymphomas [12-14]. Secondly, expression of both vascular endothelial growth factor (VEGF) and VEGF receptors by the tumor cells in a number of lymphoma subtypes suggests autocrine and paracrine pro-angiogenic survival mechanisms. Thirdly, large-scale gene expression studies in follicular lymphoma and diffuse large B-cell lymphoma (DLBCL) have demonstrated that genetic signatures expressed by stromal and infiltrating immune cells define distinct prognostic groups [15-16], with increased angiogenic activity associated with inferior outcome in DLBCL. Experimentation with anti-angiogenic strategies has shown early promise in selected subtypes. This review summarizes recent applications of antiangiogenic strategies in non-Hodgkin’s lymphoma based on current understanding of the biology of lymphoma angiogenesis.
