Abstract
BACKGROUND Several of the currently used anticancer drugs may variably affect thyroid function, with impairment ranging from modified total but not free concentration of thyroid hormones to overt thyroid disease. SUMMARY Cytotoxic agents seem to alter thyroid function in a relatively small proportion of adult patients. Anticancer hormone drugs may mainly alter serum levels of thyroid hormone-binding proteins without clinically relevant thyroid dysfunction. Old immunomodulating drugs, such as interferon-α and interleukin-2, are known to induce variably high incidence of autoimmune thyroid dysfunction. Newer immune checkpoint inhibitors, such as anti-CTLA4 monoclonal antibodies, are responsible for a relatively low incidence of thyroiditis and may induce secondary hypothyroidism resulting from hypophysitis. Central hypothyroidism is a well-recognized side effect of bexarotene. Despite their inherent selectivity, tyrosine kinase inhibitors may cause high rates of thyroid dysfunction. Notably, thyroid toxicity seems to be restricted to tyrosine kinase inhibitors targeting key kinase-receptors in angiogenic pathways, but not other kinase-receptors (e.g., epidermal growth factor receptors family or c-KIT). In addition, a number of these agents may also increase the levothyroxine requirement in thyroidectomized patients. CONCLUSIONS The pathophysiology of thyroid toxicity induced by many anticancer agents is not fully clarified and for others it remains speculative. Thyroid dysfunction induced by anticancer agents is generally manageable and dose reduction or discontinuation of these agents is not required. The prognostic relevance of thyroid autoimmunity, overt and subclinical hypothyroidism induced by anticancer drugs, the value of thyroid hormone replacement in individuals with abnormal thyrotropin following anticancer systemic therapy, and the correct timing of replacement therapy in cancer patients need to be defined more accurately in well-powered prospective clinical trials.

Talpur R, Duvic M. Pilot study of denileukin diftitox alternate dosing regimen in patients with cutaneous peripheral T-cell lymphomas. CLINICAL LYMPHOMA MYELOMA & LEUKEMIA 2012; 12:180-5. [PMID: 22521504 DOI: 10.1016/j.clml.2012.01.011] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2011] [Revised: 01/21/2012] [Accepted: 01/30/2012] [Indexed: 11/25/2022]
Abstract
UNLABELLED Better treatment and survival outcomes are needed for the rare primary cutaneous peripheral T-cell lymphomas.Five (62.5%) of 8 patients with peripheral T-cell lymphomas enrolled in a pilot study of denileukin diftitoxat 18 μg/kg per day for 5 days followed by once weekly for 24 weeks responded, including 2 complete responses, one of which is ongoing at 8 years. PURPOSE To evaluate the safety and efficacy of an alternate dosing regimen in rare primary cutaneous peripheral T-cell lymphoma variants. METHODS This is a prospective, single center, pilot study of denileukin diftitox (Dd) in patients with persistent or recurrent cutaneous peripheral T-cell lymphomas and mycosis fungoides (MF) variants, excluding Sézary syndrome (SS). Dd was administered at 18 μg/kg per day for 5 days and once weekly for 24 weeks, with response by modified skin weighed assessment tool. RESULTS Eight patients, with a median age of 76 years (range, 44-88 years), were treated between December 2003 and July 2008. Five (62.5%) of 8 patients responded, including 3 patients with CD30(+) anaplastic large-cell lymphoma (ALCL) with 2 complete responses, one ongoing at 8 years. One patient with CD8(+) and 1 patient with natural killer T cell lymphoma (NK-T) had partial responses. Progressive disease occurred in 1 patient positive for human T-cell lymphotropic virus and 1 patient with ALCL. Vascular leak syndrome (VLS) occurred in 6 (75%) of 8 patients during or just after cycle 1. Three were grade 3, and 2 of these resulted in study withdrawal. Other adverse effects included nausea or vomiting (n = 3), fatigue (n = 1), back pain (n = 1), transaminase elevations (n = 3), and elevated creatinine (n = 1). CONCLUSIONS Dd with an alternate dosing schedule was active in this small study of primary cutaneous T-cell lymphomas.

Abstract
DISEASE OVERVIEW Cutaneous T-cell lymphomas are a heterogenous group of T-cell lymphoproliferative disorders involving the skin, the majority of which may be classified as Mycosis fungoides (MF) or Sézary syndrome (SS). DIAGNOSIS The diagnosis of MF or SS requires the integration of clinical and histopathologic data. RISK-ADAPTED THERAPY Tumor, node, metastasis, and blood (TNMB) staging remains the most important prognostic factor in MF/SS and forms the basis for a "risk-adapted," multidisciplinary approach to treatment. For patients with disease limited to the skin, expectant management or skin-directed therapies is preferred, as both disease-specific and overall survival for these patients is favorable. In contrast, patients with advanced-stage disease with significant nodal, visceral, or blood involvement are generally approached with biologic-response modifiers, denileukin diftitox, and histone deacetylase inhibitors before escalating therapy to include systemic, single-agent chemotherapy. Multiagent chemotherapy may be used for those patients with extensive visceral involvement requiring rapid disease control. In highly-selected patients with disease refractory to standard treatments, allogeneic stem-cell transplantation may be considered.

Abstract
Unlike cytotoxic agents that indiscriminately affect rapidly dividing cells, newer antineoplastic agents such as targeted therapies and immunotherapies are associated with thyroid dysfunction. These include tyrosine kinase inhibitors, bexarotene, radioiodine-based cancer therapies, denileukin diftitox, alemtuzumab, interferon-α, interleukin-2, ipilimumab, tremelimumab, thalidomide, and lenalidomide. Primary hypothyroidism is the most common side effect, although thyrotoxicosis and effects on thyroid-stimulating hormone secretion and thyroid hormone metabolism have also been described. Most agents cause thyroid dysfunction in 20%-50% of patients, although some have even higher rates. Despite this, physicians may overlook drug-induced thyroid dysfunction because of the complexity of the clinical picture in the cancer patient. Symptoms of hypothyroidism, such as fatigue, weakness, depression, memory loss, cold intolerance, and cardiovascular effects, may be incorrectly attributed to the primary disease or to the antineoplastic agent. Underdiagnosis of thyroid dysfunction can have important consequences for cancer patient management. At a minimum, the symptoms will adversely affect the patient's quality of life. Alternatively, such symptoms can lead to dose reductions of potentially life-saving therapies. Hypothyroidism can also alter the kinetics and clearance of medications, which may lead to undesirable side effects. Thyrotoxicosis can be mistaken for sepsis or a nonendocrinologic drug side effect. In some patients, thyroid disease may indicate a higher likelihood of tumor response to the agent. Both hypothyroidism and thyrotoxicosis are easily diagnosed with inexpensive and specific tests. In many patients, particularly those with hypothyroidism, the treatment is straightforward. We therefore recommend routine testing for thyroid abnormalities in patients receiving these antineoplastic agents.

Abstract
Denileukin diftitox (Ontak(®)) is indicated for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma (CTCL), a rare lymphoproliferative disorder of the skin. Denileukin diftitox was the first fusion protein toxin approved for the treatment of a human disease. This fusion protein toxin combines the IL2 protein with diphtheria toxin, and targets the CD25 subunit of the IL2 receptor, resulting in the unique delivery of a cytocidal agent to CD-25 bearing T-cells. Historically, immunotherapy targeting malignant T-cells including monoclonal antibodies has been largely ineffective as cytocidal agents compared to immunotherapy directed against B-cells such as rituximab. This review will summarize the development of denileukin diftitox, its proposed mechanism of action, the pivotal clinical trials that led to its FDA approval, the improvements in quality of life, and the common toxicities experienced during the treatment of patients with CTCL. CTCL is often a chronic progressive lymphoma requiring the sequential use of treatments such as retinoids, traditional chemotherapy, or biological response modifiers. The incorporation of the immunotoxin denileukin diftitox into the sequential or combinatorial treatment of CTCL will also be addressed.

Abstract
Protein tyrosine kinase inhibitors (TKIs) have emerged as significant targets for novel cancer therapies. For patients with differentiated or medullary carcinomas unresponsive to conventional treatments, multiple novel therapies primarily targeting angiogenesis have entered clinical trials. Partial response rates up to 30% have been reported in single-agent studies, but prolonged disease stabilisation is more commonly seen. The most successful agents target the vascular endothelial growth factor receptors. Sorafenib and sunitinib have had promising preliminary results reported and are being used selectively for patients who do not qualify for clinical trials. Treatment for patients with metastatic or advanced thyroid carcinoma now emphasises clinical trial opportunities for novel agents with considerable promise. Adverse effects on thyroid function and thyroid hormone metabolism have also been seen with several TKIs, necessitating prospective thyroid function testing for all patients starting therapy.

Abstract
Cutaneous T-cell lymphoma/mycosis fungoides (CTCL/MF) is a rare lymphoproliferative disorder which can present as an indolent or as an aggressive process involving skin, lymph nodes, and blood. In stages IA, IB and IIA, it is usually managed with topical medications and phototherapy. If there is progression despite application of these treatments, or if the patient presents with a higher stage of disease, systemic chemotherapy or retinoids, rexinoids, biologic response modifiers are often necessary. Consequently, patients are often treated with a sequence of modalities and drugs. Denileukin diftitox (DD, Ontak(R)) is a targeted immunotoxin which has biological activity against malignancies expressing the IL-2 receptor. In addition to its unique mechanism of action, DD has a toxicity profile which does not overlap with most commonly used chemotherapeutic agents. CTCL/MF has been found be particularly susceptible to treatment with this agent. This review will describe the development DD, its proposed mechanism of action, the clinical trials which identified its utility in the treatment of CTCL/MF, the common toxicities encountered with this agent, and the management of these toxicities. In addition the incorporation of DD in the sequential treatment of CTCL/MF and data suggesting potential combination therapies employing this novel agent will be discussed.

Abstract
Denileukin diftitox (Ontak®) is a novel recombinant fusion protein consisting of peptide sequences for the enzymatically active and membrane translocation domain of diphtheria toxin linked to human IL-2. Denileukin diftitox specifically binds to IL-2 receptors on the cell membrane, is internalized via receptor-mediated endocytosis and inhibits protein synthesis by ADP ribosylation of elongation factor 2, resulting in cell death. This article focuses on the clinical trial that led to the US FDA approval of the drug for cutaneous T-cell lymphoma in 1999, and other investigational studies for hematologic malignancies, recurrent and refractory chronic lymphocytic leukemia, non-Hodgkin B-cell lymphoma, graft-versus-host disease and autoimmune disease, demonstrating the activity and adverse effects of the drug.

Abstract
Numerous drugs have been associated with destructive thyroiditis (subacute thyroiditis). Sunitinib, a tyrosine kinase inhibitor employed in renal cell carcinoma and gastrointestinal stromal tumors, has recently been linked to destructive thyroiditis with resultant hypothyroidism. We report a patient with transient overt thyrotoxicosis followed by hypothyroidism, apparently related to sunitinib therapy.
