Abstract
OPINION STATEMENT Choice of therapy in mycosis fungoides is based on both patient- and lymphoma-specific factors, such as disease characteristics, comorbidities, symptoms and effect on quality of life, potential associated toxicities of therapy, response and tolerance to prior lines of therapy, and convenience and practicality. Generally, we sequence therapies from least toxic, targeted, nonimmunosuppressive to more toxic, immunosuppressive and from single agent to multiple agents, as necessary. If more toxic, immunosuppressive agents are required to alleviate disease burden or symptoms, we generally use them just long enough to control the disease, then transition to a maintenance regimen with less toxic, less immunosuppressive agents.

Abstract
Retinoid therapy transformed response and survival outcomes in acute promyelocytic leukemia (APL) but has demonstrated only modest activity in non-APL forms of acute myeloid leukemia (AML). The presence of natural retinoids in vivo could influence the efficacy of pharmacologic agonists and antagonists. We found that natural RXRA ligands, but not RARA ligands, were present in murine MLL-AF9-derived myelomonocytic leukemias in vivo and that the concurrent presence of receptors and ligands acted as tumor suppressors. Pharmacologic retinoid responses could be optimized by concurrent targeting of RXR ligands (e.g., bexarotene) and RARA ligands (e.g., all-trans retinoic acid), which induced either leukemic maturation or apoptosis depending on cell culture conditions. Co-repressor release from the RARA:RXRA heterodimer occurred with RARA activation, but not RXRA activation, providing an explanation for the combination synergy. Combination synergy could be replicated in additional, but not all, AML cell lines and primary samples, and was associated with improved survival in vivo, although tolerability of bexarotene administration in mice remained an issue. These data provide insight into the basal presence of natural retinoids in leukemias in vivo and a potential strategy for clinical retinoid combination regimens in leukemias beyond APL.

Abstract
Mycosis fungoides and Sézary syndrome are the most common subtypes of all primary cutaneous lymphomas and represent complex diseases that require a multidisciplinary assessment by dermatologists, oncologists, and pathologists. Staging and work-up are critical to guarantee an optimal treatment plan that includes skin-directed and/or systemic regimens depending on the clinical stage, tumor burden, drug-related side effect profile, and patient comorbidities. However, there is no cure and patients frequently relapse, requiring repeated treatment courses for disease control. The study of the tumor microenvironment and molecular mechanisms of these rare neoplasms may assist in the development of new immune therapies providing promising treatment approaches tailored for patients with relapse/refractory disease.

Abstract
Classic tumor therapy, consisting of cytotoxic agents and/or targeted therapy, has not overcome therapeutic limitations like poor risk genetic parameters, genetic heterogeneity at different metastatic sites or the problem of undruggable targets. Here we summarize data and trials principally following a completely different treatment concept tackling systems biologic processes: the principle of communicative reprogramming of tumor tissues, i.e., anakoinosis (ancient greek for communication), aims at establishing novel communicative behavior of tumor tissue, the hosting organ and organism via re-modeling gene expression, thus recovering differentiation, and apoptosis competence leading to cancer control - in contrast to an immediate, "poisoning" with maximal tolerable doses of targeted or cytotoxic therapies. Therefore, we introduce the term "Master modulators" for drugs or drug combinations promoting evolutionary processes or regulating homeostatic pathways. These "master modulators" comprise a broad diversity of drugs, characterized by the capacity for reprogramming tumor tissues, i.e., transcriptional modulators, metronomic low-dose chemotherapy, epigenetically modifying agents, protein binding pro-anakoinotic drugs, such as COX-2 inhibitors, IMiDs etc., or for example differentiation inducing therapies. Data on 97 anakoinosis inducing schedules indicate a favorable toxicity profile: The combined administration of master modulators, frequently (with poor or no monoactivity) may even induce continuous complete remission in refractory metastatic neoplasia, irrespectively of the tumor type. That means recessive components of the tumor, successively developing during tumor ontogenesis, are accessible by regulatory active drug combinations in a therapeutically meaningful way. Drug selection is now dependent on situative systems characteristics, to less extent histology dependent. To sum up, anakoinosis represents a new substantive therapy principle besides novel targeted therapies.

Abstract
BACKGROUND Retinoids exert their biologic effects by binding to intracellular retinoic-acid receptors (RARs) and/or retinoid X receptors (RXRs). Early-stage mycosis fungoides (MF) has been effectively treated with bexarotene, an RXR-agonist, with overall response (OR) rates 54-67% and complete response (CR) rates 7-27%. Data on RAR-agonist monotherapy are limited. OBJECTIVE To analyze the effectiveness of RAR-agonist monotherapy for early-stage MF. METHODS Data on patients with early-stage MF treated with acitretin/isotretinoin monotherapy at a tertiary cutaneous lymphoma clinic in 2010-2017 were collected retrospectively from the medical files. RESULTS Thirty-five patients (26 males) of median age 50 years (range 8-83) with early-stage MF (IA 9, IB 26) underwent 37 treatment events: 25 acitretin and 12 isotretinoin at a median dosages of 0.3 mg/kg (range 0.2-0.9) and 0.2 mg/kg (range 0.1-0.7), respectively. Median time to maximal response was 6 months for both (range 1-10 for acitretin, 3-16 for isotretinoin); median treatment duration was 10 months (range 3-46) for acitretin, and 9 months (range 3-55) for isotretinoin. OR was 64% for acitretin and 80% for isotretinoin, and CR, 4% and 8%, respectively. Side-effect profiles were as previously reported for retinoids. CONCLUSIONS Early-stage MF patients may benefit from low dose RAR-agonist monotherapy, although the CR rate is low.

Abstract
Bexarotene, a synthetic retinoid licensed for the treatment of refractory cutaneous T-cell lymphoma (CTCL), has been used clinically in Poland since 2007 in 21 patients. The objective of our retrospective, multicenter study was to evaluate our experience with bexarotene therapy, including efficacy, safety, and survival outcomes. We retrospectively identified 21 adult patients who were treated with bexarotene between the years 2007 and 2012. Starting dose of bexarotene was 300 mg/m per day. The analysis included 3 patients with early-stage mycosis fungoides (MF), 16 patients with advanced-stage MF, and 2 patients with Sézary syndrome (SS). The mean duration of therapy with bexarotene was 14.5 months. Use of bexarotene resulted in an overall response rate of 81.0%, although the overall mortality rate was 52.8%. In our study, early-stage CTCL responded better than advanced-stage CTCL (100.0% vs. 77.8%, respectively). The mean time to observable response was 1.8 months, and the mean duration of the response was 16.4 months. Most significant side effects were hyperlipidemia, hypothyroidism, and a bleeding gastric ulcer. Based on the results of our analysis, bexarotene is a valuable tool in the treatment of refractory early-stage CTCL. Although a majority of patients initially responded to therapy, the high mortality rate in the advanced-stage group suggests that bexarotene does not completely resolve the therapeutic problems in all stages of CTCL. Patient stratification for bexarotene treatment may need a thorough reassessment, in that bexarotene may not be an effective drug in the very advanced stages of CTCL.

Abstract
The primary cutaneous lymphomas are a heterogeneous group of T-, Natural Killer- and B- cell neoplasms with a wide range of clinical and pathological presentations, and with very different prognoses compared to systemic lymphomas. Recent studies have shown that the skin microenvironment, which is composed of various immune cell subsets as well as their spatial distribution and T-cell interactions through different chemokines and cytokines, has an important role in the development and pathogenesis of cutaneous lymphomas and has assisted in the development of novel and more effective immunotherapies. The following review will focus on the major subtypes of primary cutaneous lymphomas, including the clinical and histological patterns, molecular hallmarks, and current and future treatment strategies.

Abstract
Retinoic acid (RA), the major bioactive metabolite of retinol or vitamin A, induces a spectrum of pleiotropic effects in cell growth and differentiation that are relevant for embryonic development and adult physiology. The RA activity is mediated primarily by members of the retinoic acid receptor (RAR) subfamily, namely RARα, RARβ and RARγ, which belong to the nuclear receptor (NR) superfamily of transcription factors. RARs form heterodimers with members of the retinoid X receptor (RXR) subfamily and act as ligand-regulated transcription factors through binding specific RA response elements (RAREs) located in target genes promoters. RARs also have non-genomic effects and activate kinase signaling pathways, which fine-tune the transcription of the RA target genes. The disruption of RA signaling pathways is thought to underlie the etiology of a number of hematological and non-hematological malignancies, including leukemias, skin cancer, head/neck cancer, lung cancer, breast cancer, ovarian cancer, prostate cancer, renal cell carcinoma, pancreatic cancer, liver cancer, glioblastoma and neuroblastoma. Of note, RA and its derivatives (retinoids) are employed as potential chemotherapeutic or chemopreventive agents because of their differentiation, anti-proliferative, pro-apoptotic, and anti-oxidant effects. In humans, retinoids reverse premalignant epithelial lesions, induce the differentiation of myeloid normal and leukemic cells, and prevent lung, liver, and breast cancer. Here, we provide an overview of the biochemical and molecular mechanisms that regulate the RA and retinoid signaling pathways. Moreover, mechanisms through which deregulation of RA signaling pathways ultimately impact on cancer are examined. Finally, the therapeutic effects of retinoids are reported.

Abstract
BACKGROUND Many targeted therapies used in the treatment of cancer can lead to the development of xerosis, but the incidence and relative risk of xerosis have not been ascertained. OBJECTIVE We conducted a systematic review and metaanalysis of clinical trials, to ascertain the incidence and risk of developing xerosis after taking anticancer drugs. METHODS The PubMed (1966-October 2013), Web of Science (January 1998-October 2013), and American Society of Clinical Oncology abstracts (2004-2013) databases were searched for clinical trials of 58 targeted agents. Results were calculated using random or fixed effects models. RESULTS The incidences of all- and high-grade xerosis were 17.9% (95% confidence interval [CI]: 15.6-20.4%) and 1.0% (95% CI: 0.9-1.5%), respectively. The risk of developing all-grade xerosis was 2.99 (95% CI: 2.0-4.3), and it varied across different drugs (P < .001). LIMITATIONS The reporting of xerosis may vary among clinicians and institutions, and the incidence may be affected by age, concomitant medications, comorbidities, and underlying malignancies or skin conditions. CONCLUSION Patients receiving targeted therapies have a significant risk of developing xerosis. Patients should be counseled and treated early for this symptom to prevent suboptimal dosing and quality of life impairment.

Abstract
Both mycosis fungoides (MF) and Sézary syndrome (SS) have a chronic, relapsing course, with patients frequently undergoing multiple, consecutive therapies. Treatment is aimed at the clearance of skin disease, the minimization of recurrence, the prevention of disease progression, and the preservation of quality of life. Other important considerations are symptom severity, including pruritus and patient age/comorbidities. In general, for limited patch and plaque disease, patients have excellent prognosis on ≥1 topical formulations, including topical corticosteroids and nitrogen mustard, with widespread patch/plaque disease often requiring phototherapy. In refractory early stage MF, transformed MF, and folliculotropic MF, a combination of skin-directed therapy plus low-dose immunomodulators (eg, interferon or bexarotene) may be effective. Patients with advanced and erythrodermic MF/SS can have profound immunosuppression, with treatments targeting tumor cells aimed for immune reconstitution. Biologic agents or targeted therapies either alone or in combination--including immunomodulators and histone-deacetylase inhibitors--are tried first, with more immunosuppressive therapies, such as alemtuzumab or chemotherapy, being generally reserved for refractory or rapidly progressive disease or extensive lymph node and metastatic involvement. Recently, an increased understanding of the pathogenesis of MF and SS with identification of important molecular markers has led to the development of new targeted therapies that are currently being explored in clinical trials in advanced MF and SS.

Abstract
In pursuit of effective therapeutic agents for the estrogen receptor (ER)-negative breast cancer, we previously showed that bexarotene reduced mammary tumor development by 75% in ErbB2 mice. To further improve the effectiveness of breast cancer prevention, we have now investigated the effects of a combinatorial therapy consisting of two cancer preventive drugs. On the basis of the hypothesis, rexinoid LG100268 plus tamoxifen would more effectively prevent the development of both ER-positive and ER-negative breast cancer. We treated p53-null mammary gland mice with tamoxifen and LG100268, individually and in combination. By 60 weeks of age, vehicle-treated mice developed tumors in 52% of transplanted mammary glands, whereas mice treated with tamoxifen and LG100268 developed tumors in only 13% of transplanted mammary glands. To further define the mechanistic effects of this combinatorial treatment, we investigated the effects of tamoxifen and LG100268 on mammary tissue biomarkers. In mammary tissue harvested before tumor development, the proliferation markers Ki67 and cyclin D1 were significantly reduced in mice treated with the combination therapy. In addition, the rexinoid target genes ABCA1 and ABCG1 were induced in both the rexinoid and combination treatment groups, whereas expression remained constant in tamoxifen group. These results show that tamoxifen-LG100268 combinatorial treatment is more effective in preventing mammary tumors than either agent alone. In addition, these studies have identified relevant tissue biomarkers that can be used to show the effect of these agents on mammary tissue. These results support the development of clinical trials of antiestrogen and rexinoid combinatorial therapy for the prevention of patients with high-risk breast cancer.

Abstract
Cutaneous T-cell lymphomas (CTCL) are a heterogeneous group of malignancies derived from skin-homing T cells. The most common forms of CTCL are Mycosis Fungoides (MF) and Sezary Syndrome (SS). Accurate diagnosis remains a challenge due to the heterogeneity of presentation and the lack of highly characteristic immunophenotypical and genetic markers. Over the past decade molecular studies have improved our understanding of the biology of CTCL. The identification of gene expression differences between normal and malignant T-cells has led to promising new diagnostic and prognostic biomarkers that now need validation to be incorporated into clinical practice. These biomarkers may also provide insight into the mechanism of development of CTCL. Additionally, treatment options have expanded with the approval of new agents, such as histone deacetylase inhibitors. A better understanding of the cell biology, immunology and genetics underlying the development and progression of CTCL will allow the design of more rational treatment strategies for these malignancies. This review summarizes the clinical epidemiology, staging and natural history of MF and SS; discusses the immunopathogenesis of MF and the functional role of the malignant T-cells; and reviews the latest advances in MF and SS treatment.

Abstract
The successful demonstration that the selective estrogen receptor modulators (SERMs) tamoxifen and raloxifene reduce the risk of breast cancer has stimulated great interest in using drugs to prevent breast cancer in high-risk women. In addition, recent results from breast cancer treatment trials suggest that aromatase inhibitors may be even more effective at preventing breast cancer than are SERMs. However, while SERMs and aromatase inhibitors do prevent the development of many estrogen-receptor (ER)-positive breast cancers, these drugs do not prevent the development of ER-negative breast cancer. Thus, there is an urgent need to identify agents that can prevent ER-negative breast cancer. We have studied the cancer preventative activity of several classes of drugs for their ability to prevent ER-negative breast cancer in preclinical models. Results from these studies demonstrate that rexinoids (analogs of retinoids that bind and activate RXR receptors), tyrosine kinase inhibitors (such as EGFR inhibitors and dual kinase inhibitors that block EGFR and HER2/neu signaling), and cyclo-oxygenase 2 (COX-2) inhibitors all prevent ER-negative breast cancer in transgenic mice that develop ER-negative breast cancer. Other promising agents now under investigation include vitamin D and vitamin D analogs, drugs that activate PPAR-gamma nuclear receptors, and statins. Many of these agents are now being tested in early phase cancer prevention clinical trials to determine whether they will show activity in breast tissue and whether they are safe for use in high-risk women without breast cancer. The current status of these studies will be reviewed. It is anticipated that in the future, drugs that effectively prevent ER-negative breast cancer will be used in combination with hormonal agents such SERMs or aromatase inhibitors to prevent all forms of breast cancer.

Abstract
CD8+ cutaneous T-cell lymphoma (CTCL) is a relatively rare subset of the non-Hodgkins lymphomas. Bexarotene has been FDA-approved for the treatment of CTCL, but previous studies have been conducted on CD4+ CTL and there have been no reports about its use in CD8+ CTCL. Herein, we report on a patient whose CD8+ CTCL completely responded to treatment with bexarotene.

Abstract
PURPOSE To test whether a novel rexinoid, LG100268, prevents the development of preinvasive and invasive estrogen receptor-negative mammary tumorigenesis in MMTV-erbB2 mice. EXPERIMENTAL DESIGN For invasive breast cancer prevention, MMTV-erbB2 mice were treated with daily gastric gavage of vehicle, LG100268 (10 mg/kg), or LG100268 (100 mg/kg) for long term starting at 3 months of age. For preinvasive lesion study, mice were treated with daily gastric gavage of vehicle or LG100268 (100 mg/kg) for 4 months. RESULTS Long-term treatment with LG100268 significantly prevented invasive mammary tumor development. Median time (age) to tumor development was delayed from 217 days in vehicle group to 357 days in low-dose group. In high-dose group, only 2 of 20 mice developed tumors after 430 days of treatment. Short-term treatment of LG100268 significantly prevented the development of preinvasive mammary lesions including hyperplasia and ductal carcinoma in situ. The cancer prevention effect was associated with reduced expression of Ki67 and cyclin D1 in mammary glands by >80%. CONCLUSION Rexinoid LG100268 is an effective chemopreventive agent in preventing the development of both malignant and premalignant mammary lesions in MMTV-erbB2 mice.

Abstract
Breast cancer prevention has focused heavily on endocrine interventions using selective estrogen receptor modulators and aromatase inhibitors. Tamoxifen, the stereotypical selective estrogen receptor modulator, significantly reduces the breast cancer incidence in high-risk women. Selective estrogen receptor modulators and aromatase inhibitors, however, only prevent the development of estrogen receptor-positive breast cancer and have no effect in reducing the risk of estrogen receptor-negative breast cancer, which has poor prognosis. Thus, preventive therapies for estrogen receptor-negative breast cancer are clearly needed. Recently, a number of novel chemopreventive agents targeting nonendocrine pathways have been developed and shown to prevent estrogen receptor-negative mammary tumorigenesis in animal models. These agents include rexinoids, selective cyclooxygenase-2 inhibitors, tyrosine kinase inhibitors, and others. In this review, we discuss the effects of selective estrogen receptor modulators and aromatase inhibitors, as well as novel agents targeting nonendocrine pathways. We also discuss the promise of combining these agents for the effective prevention of all forms of breast cancer.

Abstract
Tamoxifen (TAM) is a nonsteroidal antiestrogen that prevents estrogen receptor-positive breast cancer in rodents and humans. Bexarotene (BEX), a selective agonist for retinoid X receptors, inhibits mammary carcinogenesis in rodents. The present study was conducted to support the preclinical development of TAM (tamoxifen citrate) + BEX for use in breast cancer chemoprevention, and to investigate the influence of these agents on hepatic gene expression. Female CD rats (20 per group) received daily oral (gavage) exposure to TAM (0 or 60 microg/kg/day) and/or BEX (0, 5, 15, or 45 mg/kg/day) for a minimum of 90 days. BEX induced mild, dose-related anemia and dose-related increases in serum alkaline phosphatase, cholesterol, triglycerides, and calcium levels, and increased platelet counts. TAM had no biologically significant effect on any clinical pathology parameter and did not alter the effects of BEX on these endpoints. Microscopic alterations induced by BEX included epidermal hyperplasia, hyperkeratosis (stomach), and cytoplasmic clearing (liver). Microscopic changes in TAM-treated rats were limited to mucous cell hypertrophy in the cervix and vagina. The toxicity of administration of the combination of TAM + BEX can generally be predicted on the basis of the toxicity of each drug as a single agent. BEX induced dose-related alterations in the expression of several genes involved in steroid, drug, and/or fatty acid metabolism; TAM did not alter these effects of BEX. Differential expression of genes involved in drug and lipid metabolism may underlie the observed effects of BEX on cholesterol and triglyceride levels and its effects on liver histology.

Abstract
Retinoids are biologic regulators of differentiation, proliferation, apoptosis, and immune response. Retinoids (all-trans retinoic acid, 13-cis-retinoic acid, and the synthetic analogs isotretinoin, etretinate, and acitretin) have been used for years as monotherapy and/or in combination for treatment of cutaneous T-cell lymphomas (CTCL). Orally administered bexarotene, the first synthetic highly selective retinoid X receptor retinoid to be approved by the Food and Drug Administration for CTCL, was shown to be active against the cutaneous manifestations of all stages of CTCL. The topical gel formulation was also effective for early cutaneous manifestations of CTCL or as an adjunct to systemic or phototherapy. Use of retinoids in future long-term clinical trials and their eventual application in CTCL regiments will require strategies to decrease the side effects of existing retinoids, identify novel receptor subtype-selective retinoids with better therapeutic index, and explore biologically based synergistic combination therapies with other active agents.

Abstract
Primary cutaneous T-cell lymphomas encompass a spectrum of non-Hodgkin's lymphomas that are characterised by clonal proliferation of skin-homing malignant T lymphocytes. Mycosis fungoides and the leukaemic variant Sézary syndrome, collectively referred to as cutaneous T-cell lymphomas, are the most common entities. No curative therapy exists and patients ultimately develop advanced or relapsed disease that is refractory to standard treatment options. Therefore, there is a great need for the development of novel emerging therapies. Bexarotene is the first synthetic nuclear retinoid X receptor-selective retinoid approved by the FDA for the treatment of refractory cutaneous T-cell lymphoma in all stages, as both an oral capsule and a topical gel formulation. Bexarotene was found to induce apoptosis in a variety of preclinical in vitro and in vivo models including cutaneous T-cell lymphoma cells, and has shown efficacy in two multi-centre, open-label Phase II - III clinical trials for early and advanced stages of cutaneous T-cell lymphoma in patients who have failed or were refractory to standard therapies. New insights into the immunomodulatory function of bexarotene have indicated opportunities for combined treatment with IFN-alpha, denileukin diftitox or phototherapy. This article reviews the biological properties, pharmacokinetics, clinical efficacy, safety and role of bexarotene in the treatment of cutaneous T-cell lymphoma.

Abstract
Retinoids comprise a family of polyisoprenoid lipids that include vitamin A (retinol) and its various natural and synthetic analogues. Retinoids are compounds with multiple actions. They are involved in the control of cell proliferation, cell differentiation, and embryonic development. Each retinoid has its own profile of pharmacologic properties that determines its usefulness in clinical dermatology or oncology. Although numerous synthetic retinoids have been synthesized, their biological activities are usually associated with clinical disadvantages such as toxicity and teratogenicity. Retinoids that bind to both the retinoic acid receptor and retinoid X receptor subtypes have shown clinical activity in hematologic malignancies and can mediate genes associated with both growth and differentiation. Retinoid X receptor-specific rexinoids have also shown efficacy in the treatment of cutaneous T-cell lymphomas, but their exact mechanism of action is unclear. This article summarizes the clinical relevance of both groups of compounds in this important patient population.

Abstract
Primary cutaneous T-cell lymphomas (CTCLs) encompass a clinically and biologically heterogeneous group of non-Hodgkin lymphomas (NHLs) defined by clonal proliferation of skin-homing malignant T lymphocytes and natural killer cells. They account for up to 75% to 80% of all cutaneous lymphomas. The current WHO-EORTC classification of cutaneous lymphomas with primary cutaneous manifestations lists 13 entities. The most common subtypes—mycosis fungoides, Sézary syndrome, primary cutaneous anaplastic large cell lymphoma, and lymphomatoid papulosis—which represent approximately 95% of CTCLs, will be discussed in the following review. Each entity has unique biological characteristics and clinical course. Topical and/or systemic therapies are employed based on the stage of the disease and the tempo of progression.

Abstract
PURPOSE OF REVIEW Cutaneous T-cell lymphomas represent clinically and biologically a heterogeneous group of non-Hodgkin lymphomas according to the new revised European Organization for Research and Treatment of Cancer and World Health Organization consensus classification for cutaneous lymphomas. Recent progress in immune and molecular biology and novel therapeutic targets have increased our understanding of these diseases and have led to novel treatment approaches. This review outlines the most recent advances. RECENT FINDINGS New immunologic and molecular findings may influence tumor phenotype and growth and provide a biologic basis for novel treatment approaches. Several reports have focused on new prognostic markers. Among the novel therapies for cutaneous T-cell lymphoma, interleukin-2 fusion toxins, monoclonal antibodies, histone deacetylase inhibitors, and immunomodulatory cytosine-phosphorothiolated guanine oligomers have shown promising results and are under further investigation. SUMMARY This review provides an update of recent findings of immunologic, molecular, and cytogenetic features and treatment approaches for patients with cutaneous T-cell lymphoma with special emphasis on mycosis fungoides and Sezary syndrome.
