Abstract
COVID-19 is a rapidly spreading disease, which has caught the world by surprise. Millions of people suffer from illness, and the mortality rates are dramatically high. Currently, there is no specific and immediate treatment for this disease. Remedies are limited to supportive regiments and few antiviral and anti-inflammatory drugs. The lack of a definite cure for COVID-19 is the reason behind its high mortality and global prevalence. COVID-19 can lead to a critical illness with severe respiratory distress and cytokine release. Increased oxidative stress and excessive production of inflammatory cytokines are vital components of severe COVID-19. Micronutrients, metalloids, and vitamins such as iron, manganese, selenium, Zinc, Copper, vitamin A, B family, and C are among the essential and trace elements that play a pivotal role in human nutrition and health. They participate in metabolic processes that lead to energy production. In addition, they support immune functions and act as antioxidants. Therefore, maintaining an optimal level of micronutrients intake, particularly those with antioxidant activities, is essential to fight against oxidative stress, modulate inflammation, and boost the immune system. Therefore, these factors could play a crucial role in COVID-19 prevention and treatment. In this review, we aimed to summarize antiviral properties of different vitamins and minerals. Moreover, we will investigate the correlation between them and their effects in COVID-19 patients.

Abstract
The 2020 global outbreak of the novel coronavirus (SARS-CoV-2 or COVID-19) is a serious threat to international health, and thus, there is an urgent need for discovery of novel therapies or use of repurposed drugs that can make a significant impact on slowing the spread of the virus. Type 1 interferons (IFN-I) are a family cytokines of the early innate immune response to viruses that are being tested against SARS-CoV-2. However, coronaviruses similar to SARS-CoV-2 can suppress host IFN-I antiviral responses. Retinoids are a family molecules related to vitamin A that possess robust immune-modulating properties, including the ability to increase and potentiate the actions of IFN-I. Therefore, adjuvants such as retinoids, capable of increasing IFN-I-mediated antiviral responses, should be tested in combinations of IFN-I and antiviral drugs in pre-clinical studies of SARS-CoV-2.

Abstract
BACKGROUND We have previously conducted phase II trials with a combination of 13-cis-retinoic acid (13-cRA), interferon-alpha2a (IFN-alpha2a), and alpha-tocopherol (alpha-TF) in patients with advanced oral premalignant lesions and locally advanced head and neck cancer in the adjuvant settings and achieved promising outcomes. The present study was conducted in vitro to elucidate the mechanisms of anti-tumor activity of this 3-drug combination in squamous cell carcinoma of the head and neck (SCCHN). METHODS Five SCCHN cell lines were treated with 13-cRA, IFN-alpha2a, and alpha-TF as single agents or 2- to 3-drug combinations for 72 hours. Inhibition of cell growth and cell cycle progression and induction of apoptosis by the treatments were evaluated. RESULTS Our results demonstrated that although each single-agent and 2-drug combination showed a certain level of cell growth inhibition, the 3-drug combination apparently further inhibited cell growth in comparison to any single agents and 2-drug combinations in the 5 SCCHN cell lines. Cell cycle analysis on Tu212 and 886LN cells by flow cytometry exhibited significant accumulation of the cells at S phase in the 3-drug combination. On the other hand, Annexin-V binding assay demonstrated that the 3-drug combination induced more profound apoptosis than any of the single agents or 2-drug combinations. In parallel, proteolytic cleavages of pro-caspase-8, -9, -3 and poly (ADP ribose) polymerase as well as caspase-3 activity induced by the 3-drug treatment were observed. CONCLUSIONS Our data suggests that 3-drug combination biochemopreventive regimen has cooperative inhibitory effect on the growth of SCCHN cells. Both cell cycle arrest and apoptosis contribute to cell growth inhibition of this 3-drug combination therapy.

Abstract
Inhibition of c-myc and N-myc genes by dsRNAs in carcinoma and neuroblastoma cells was investigated. siRNA-Ex3 targeted to the third exon of c-myc gene was found to decrease the level of c-myc but not N-myc mRNA and decrease the rate or even arrest proliferation of c-myc overexpressing cell lines KB-3-1 and SK-N-MC. This siRNA did not affect proliferation of IMR-32 (which overexpress N-myc). siRNA-Ex2 corresponding (with 1-2 mismatches) to the conservative region of the second exon of both c- and N-myc was able to downregulate both genes and to reduce proliferation of KB-3-1, SK-N-MC, and IMR-32 cells. Long dsRNA corresponding to the 3 exon of c-myc gene (dsMyc), poly(I:C), and GU-rich siRNA-I, corresponding to the intron sequence of human MDR1 gene demonstrated high antiproliferative activity in experiments with KB-3-1 cells. Short-term elevation of PKR or/and OAS1 mRNA levels was detected in the cells affected by interferon inducer poly(I:C). dsMyc, poly(I:C), and even siRNA-I, which could not affect c-myc mRNA by RNA interference mechanism, were found to inhibit proliferation of the KB-3-1 cells and to decrease the mRNA level of interferon-sensitive genes c-myc and beta-actin.

Abstract
Suppression of c-myc proto-oncogene expression by small interfering RNA (siRNA) in human epidermoid carcinoma KB-3-1 and neuroblastoma SK-N-MC cell lines was investigated. The siRNA duplex targeted to the exon 3 of c-myc mRNA (siRNA-I) was prepared by in vitro transcription using T7 RNA polymerase and short double-stranded DNA (dsDNA) templates. siRNA-I was shown to efficiently decrease c-myc mRNA expression in both tumor cell lines and to arrest their proliferation. Incubation of KB-3-1 cells with 150 nM siRNA-I results in a 92% decrease in the c-myc mRNA level and an 83% decrease in the protein level. In SK-N-MC cells, 150 nM siRNA-I causes a 60% decrease in the c-myc mRNA level and a 55% decrease in the protein level. The reduction of the c-myc mRNA level correlates with the inhibition of cell proliferation; 150 nM siRNA-I causes a 2.5-fold reduction in the SK-N-MC proliferation rate and a 15-fold decrease in the proliferation rate and complete arrest of cell division in KB-3-1 cells. siRNA-I has little effect on proliferation of the IMR-32 cells that overexpress the N-myc but not the c-myc gene, demonstrating that siRNA-I antiproliferation activity is mediated by specific block of c-myc expression.

Abstract
When cells were incubated in the presence of both interferon-gamma (IFN-gamma) and all-trans retinoic acid (ATRA), the concentration of IFN-gamma required to induce apoptosis of B-cell lymphoma cells was much lower than that required for myeloid or erythroid cell lines. The concentration of IFN-gamma that effectively inhibited the proliferation of BALM-3 cells was 1/40 of that required for BALM-1 cells. STAT-1 phosphorylation, IRF-1 mRNA and protein expression and RAR-beta expression were enhanced to a greater degree in BALM-3 cells treated with IFN-gamma and ATRA than in BALM-1 cells treated with IFN-gamma and ATRA, suggesting that these IFN-gamma related genes were involved in the induction of apoptosis of BALM-3 cells.

Abstract
We report an 80-year-old man suffering from an angiosarcoma of the scalp. Because of the wide extent of the lesions, surgery was not performed. Instead, the patient was treated with electron-beam radiation. Later, the patient failed to benefit from radiotherapy demonstrated by a local relapse and new malignant lesions. Additionally, a cervical lymph node metastasis appeared for the first time. Subsequently, we successfully administered liposomal doxorubicin (Caelyx(R)). Shortly after administration of two cycles the scalp angiosarcoma showed a clear regression. Following six cycles, the patient clinically showed a complete remission of all skin lesions and the cervical lymph node; metastasis was confirmed by histology and fine needle aspiration, respectively. Liposomal and pegylated doxorubicin, a cytostatic drug belonging to the anthracyclines, has already shown to be effective and mostly well tolerated in the therapy of acquired immune deficiency syndrome-related Kaposi's sarcoma and very recently in cutaneous T-cell lymphoma, too. Caelyx(R) appears to be a promising alternative to conventional treatment of cutaneous angiosarcoma.

Abstract
Links between human papillomaviruses (HPVs) and cervical cancer were first suspected almost 30 years ago. DNA of specific HPV types has since been found in almost all cervical cancer biopsies. HPV oncogenes that are expressed in these cells are involved in their transformation and immortalization, and are required for the progression towards malignancy. Epidemiological studies have underlined that HPVs are the main aetiological factor for cervical cancer. But how has this knowledge been translated into the clinic to allow the prevention, screening and treatment of cervical cancer?

Abstract
Human papillomavirus (HPV) is an important etiological agent in the genesis of cervical cancer. HPV-positive cervical tumors and human papillomavirus-positive cell lines display increased epidermal growth factor receptor (EGFR) expression, which is associated with increased cell proliferation. ECE16-1 cells are an HPV-immortalized human ectocervical epithelial cell line that is a model of HPV-associated cervical neoplasia and displays elevated EGFR levels. In the present study, we evaluated the effects of receptor-selective retinoid ligands on EGFR-associated signal transduction. We show that retinoic acid receptor (RAR)-selective ligands reduce EGFR level and the magnitude and duration of EGFR activation in EGF-stimulated cells. These effects are reversed by cotreatment with an RAR antagonist. To identify the mechanism, we examined the effects of retinoid treatments on EGF-dependent signaling. Stimulation with EGF causes a biphasic activation of the ERK1/2 MAPK. The first peak of activation is present at 20 min, and the second is present at 36 h. This activation subsequently leads to an increase in the cyclin D1 level and increased cell proliferation. Simultaneous treatment with EGF and a RAR-selective retinoid inhibits both phases of ERK1/2 activation, completely eliminates the cyclin D1 induction, and suppresses EGF-dependent cell proliferation. This effect is specific as retinoid treatment does not alter the level or activity of other EGFR-regulated kinases, including AKT and the MAPKs p38 and JNK. Retinoid X receptor-selective ligands, in contrast, did not regulate these responses. These results suggest that RAR ligand-associated down-regulation of EGFR activity reduces cell proliferation by reducing the magnitude and duration of EGF-dependent ERK1/2 activation.

Abstract
Numerous evidence has demonstrated the involvement in growth control of interferon (IFN) regulatory factor-1 (IRF-1), which shows tumor suppressor activity. IRF-1 is a well-studied member of the IRF transcription factors that reveals functional diversity in the regulation of cellular response by activating expression of a diverse set of target genes, depending on the cell type and on the specific stimuli. IRF-1 gene rearrangements may be a crucial point in the pathogenesis of some cancer types. Furthermore, different aspects of the tumor suppressor function of IRF-1 may be explained, at least in part, by the observations that IRF-1 is a regulator of cell cycle and apoptosis and that its inactivation accelerates cell transformation. Studies on gene knockout mice contributed greatly to the clarification of these multiple IRF-1 functions. We summarize our current knowledge of the antigrowth effect of IRF-1, focusing also on a more general involvement of IRF-1 in mediating negative regulation of cell growth induced by numerous cytokines and other biologic response modifiers.

Abstract
Retinoids inhibit the proliferation of several types of tumour cells, and are used for patients with several malignant tumours. In this study, we examined the effect of retinoic acids (RAs) on the invasive potentials of the oral squamous cell carcinoma (SCC) cells, BHY and HNt. BHY cells expressed all of retinoid nuclear receptors (RARalpha, beta, gamma, and RXRalpha) and cytoplasmic retinoic acid binding proteins (CRABP1 and CRABP2). HNt cells lacked the expression of RARbeta, but expressed other nuclear receptors and CRABPs. All-trans retinoic acid (ATRA) and 13-cis retinoic acid (13-cisRA) (10(-6)and 10(-7)M) inhibited the growth of the cells, but low-dose ATRA and 13-cisRA (10(-8)M) marginally affected the growth of the cells. Surprisingly, low-dose RAs enhanced the activity of tissue-type plasminogen activator (tPA), and activated pro-matrix metalloproteinases (proMMP2 and proMMP9). Activation of proMMP2 and proMMP9 was inhibited by aprotinin, a serine-proteinase, tPA inhibitor. Furthermore, low-dose RAs enhanced the in vitro invasiveness of BHY cells. These results indicate that low-dose RAs enhances the in vitro invasiveness of oral SCC cells via an activation of proMMP2 and proMMP9 probably mediated by the induction of tPA.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive epithelial malignancy that is now the sixth most common neoplasm in the world today. Approximately 50,000 cases in the United States and more than 500,000 cases worldwide will be diagnosed in 2000 [1]. Despite numerous advances in treatment utilising the most recent protocols for surgery, radiation and chemotherapy, the long-term survival has remained at less than 50% over the past 40 years [2]. This poor long-term survival is due to a number of variables including delayed diagnosis as well as the frequent development of multiple primary tumours. Therefore, in addition to early detection, continued emphasis must be placed on preventing the development of new primaries as well as establishing more effective treatments for individuals who present with advanced disease. This review will summarise some of the recent advances in the realms of chemotherapy and radiation therapy. In addition, it will discuss the present status of chemoprevention in HNSCC. Finally, we will discuss the rationale for the use of anti-angiogenic agents as one possible means of developing new chemopreventive protocols that result in reduced toxicity while maintaining similar clinical efficacies.

Abstract
Vitamin A (VA) deficiency compromises antibody responses to T-cell-dependent antigens such as tetanus toxoid, but this effect can be reversed through administration of retinol or retinoic acid (RA). To test whether RA and polyriboinosinioc : polyribocytidylic acid (PIC), a known inducer of several forms of interferon (IFN), can cooperate to increase specific immunoglobulin (Ig)G and IgM production during VA deficiency, rats and mice were made VA-deficient, immunized with TT and treated with all-trans-RA, PIC or their combination. VA-deficient rats produced low primary and secondary anti-tetanus IgG responses (VA-deficient controls v. VA-sufficient controls P < 0.001), although total IgG was slightly elevated when compared with VA-sufficient control rats. Although RA administered alone elevated antibody production during VA deficiency to control levels, RA combined with PIC synergistically enhanced these responses (RA and PIC group v. all other groups P < 0.0001). In contrast, Balb/c mice maintained on a VA-deficient diet and immunized in a similar fashion showed no impairment in antigen-specific IgG levels, but treatment with a combination of RA and PIC still evoked an additive enhancement in antigen-specific antibody production. Additionally, RA and PIC administration to VA-sufficient mice resulted in elevated antibody responses, suggesting that this combination should be evaluated further for its immuno-stimulatory effects.

Abstract
Acute promyelocytic leukemia (APL) has been regarded as the paradigm for therapeutic approaches utilizing differentiating agents, due to the fact that almost 95% of patients undergo complete remission when treated with all-trans retinoic acid (ATRA). However, complete clinical remission with ATRA alone is always transient, and relapse in APL is almost invariably associated with the acquisition of resistance to ATRA. Acquired resistance to ATRA in APL cell lines and in some APL clinical cases can be partially overcome by interferons (IFNs), cytokines which have well established tumor-growth suppressive activities. APL is associated in 99% of cases with a 15;17 translocation that fuses the PML and Retinoic Acid Receptor alpha (RARalpha) genes. RARalpha is one of the Retinoic Acid (RA) nuclear receptors which mediates, at the transcriptional level, ATRA differentiating and growth suppressive activity. PML is a tumor-growth suppressor whose expression is directly regulated by IFNs. Here we review the molecular mechanisms by which IFNs and RA can cooperate in controlling cell growth and differentiation of normal hemopoietic cells and leukemic cells, focusing on APL as a model system.

Abstract
Several lines of evidence have demonstrated that IFNs could be relevant in the treatment of certain neoplastic diseases such as carcinomas. In particular, IFN-alpha, in addition to the anti-proliferative and cytostatic effects, was demonstrated to be capable of inducing cell death by apoptosis both in vivo and in vitro. Numerous protocols have also been proposed which consider the association of IFN-alpha with other drugs. Among these are retinoids, a class of compounds capable of inducing inhibition of cell growth and differentiation. We address the question here by analyzing the role of cell adhesion in susceptibility to IFN-alpha, RA and their combination of a human cell line derived from a squamous carcinoma of the cervix, the Bcl-2-negative SiHa cell line. In this context, cytoskeleton components and several surface molecules playing a role in cell substrate and cell-to-cell relationships have been evaluated. We found that RA treatment is capable of improving stress fiber formation, decreasing cell detachment and increasing cell-adhesion capability. However, no variations in the ability to adhere to specific extracellular-matrix molecules were found in RA-treated cells. No quantitative changes were detected in integrins involved as receptors for extracellular matrix molecules (VLAI-VLA5) or in other cell-adhesion-associated molecules (e.g., CD44). By contrast, 2 important molecules involved in cell-adhesion processes appeared to be up-regulated by RA exposure: focal adhesion kinase and E-cadherin, involved in adhesion plaque formation and cell-to-cell contacts, respectively. Keeping in mind the importance of adhesion properties in the cell-growth pathway, our findings could be of interest in the study of carcinoma-cell proliferation and metastatic potential.

Abstract
The effects of the administration of a 3-day course of 13-cis retinoic acid in combination with interferon a [RA/IFN] on the leukemia cells was measured in vivo in 43 patients with chronic myelogenous leukemia. The administration of RA/IFN was associated with a significant fall in the white blood cell count of patients with chronic-phase disease and with a fall in the percentage S-phase cells in CML patients regardless of the stage of their leukemia. In two thirds of the patients studied the administration of RA/IFN was also associated with an increase in marrow apoptosis. The cytokine combination also suppressed bcl-2 and myc expression in a minority of patients and such expression appears to be associated with response to a treatment regimen which includes RA/IFN. These studies are the first to directly assess the effects of the combination of RA/IFN on chronic myelogenous leukemia cells in vivo in patients. These effects, if seen in other malignant diseases, could account for the therapeutic benefit which has been associated with the administration of this combination of biological agents to patients with malignant disease.

Abstract
The evolving understanding of the molecular mechanisms of carcinogenesis establishes that the long latency period would offer numerous opportunities for intervention before the final step of fully developed malignancy has been reached. Immunoprevention of cancer may be a new approach to cancer control, by eliminating the cellular minimal deviations that are seen in the early phases of carcinogenesis. Available results of immunotherapy of preneoplastic lesions and data on anticarcinogenesis with immunoregulators in experimental models are in good accordance with theoretical expectations. However, clinical research on immunoregulators still focuses on the treatment of advanced cancer. The major problem hampering a wider application of immunoregulators in cancer prevention is the possibility of potential adverse effects, which are largely unknown. The promotion of future research in this area is essential. Moreover, the ethical issues of intervention trials in cancer must be discussed, by considering the potential psychological and social consequences.

Abstract
PURPOSE The purpose of this pilot study was to determine the maximum tolerated dose of alpha-2a interferon given by subcutaneous injection and combined with high dose pelvic radiation for locally advanced or recurrent rectal cancer. METHODS AND MATERIALS In this Phase I pilot study, patients with locally advanced, unresectable, or recurrent rectal cancer with or without distant metastases received external beam pelvic radiotherapy over 5 to 6 weeks combined with escalating doses of alpha-2a interferon. Interferon was escalated in increments of 3 million units for each patient cohort, starting at 3 million units subcutaneously 3 days weekly during pelvic radiation. Radiotherapy consisted of 44 Gy (2 Gy fractions) to the pelvis followed by a boost of 6 Gy or 16 Gy to gross pelvic tumor, depending on the presence or absence of small bowel in the boost field, respectively. Between 1991 and 1993, 10 patients were treated on this study, five with locally advanced and five with locally recurrent rectal cancer. RESULTS At 6 million units of interferon, Grade 3 (WHO criteria) toxicities were as follows: diarrhea (one), leukopenia (one), and neutropenia (one). One patient died of a massive GI bleed at this dose level. Death was not felt to be treatment related. The maximum tolerated dose of interferon was 3 million units three times weekly with radiation. Three patients had unusual complications at 4, 6, and 6 months possibly related to treatment. The first had a right distal ureteric stricture with a right urinoma. The second had a sudden left foot drop that has remained stable. The third had sudden onset of bilateral lower extremity paraplegia with spontaneous resolution. CONCLUSIONS The maximally tolerated dose of interferon alpha-2a given three times weekly during pelvic radiation was 3 million units based on acute side effects. Nevertheless, even at this dose level there were three unusual subacute complications possibly related to treatment. Caution is advised when combining interferon alpha-2a with high dose pelvic radiation, especially in patients with predisposing conditions (such as diabetes) for radiotherapy complications.

Abstract
Acute promyelocytic leukemia (APL) is uniquely sensitive to treatment with all-trans retinoic acid (ATRA) which exerts its action via a well-documented cytodifferentiating mechanism. The combination of this retinoid with anthracyclines gives high percentages of complete remission and is now considered the optimal induction treatment for APL patients. Continuous treatment with ATRA, however, induces accelerated drug catabolism, with progressive decline in plasma drug concentrations potentially to below the levels required to maintain differentiation of leukemic cells. This process, which occurs rapidly and consistently has led to the hypothesis that the development of acquired clinical resistance to ATRA in APL has a pharmacologic basis. The rapid autoinduction of the hypercatabolic state precludes maintenance with continuous ATRA oral dosing, and is a limitation of better use of the drug both in APL and in other disorders in which it could be beneficial. Here we briefly review the pharmacologic alterations of ATRA metabolism induced by continuous oral administration, the clinical implications of this phenomenon, and the strategies currently under investigation to prevent or overcome the induced catabolism of this retinoid.

Abstract
Interferons (IFN) and retinoids failed to inhibit the growth of a number of breast tumor cell lines. However, a combination of these two biological response modifiers significantly suppressed the cell growth at pharmacologically achievable doses. The molecular basis for such enhancement was investigated in MCF-7, a breast tumor cell line resistant to growth inhibition by IFN-beta. Pretreatment of cells with retinoic acid (RA) for 16 h followed by IFN-beta, but not the converse, induced cytotoxic effects in the cells. Continuous presence of RA was not necessary, although it enhanced the degree of cell death when present. Further analyses revealed that IFN-beta failed to activate IFN-stimulated gene transcription. However, IFN-beta strongly up-regulated the gene expression in RA-pretreated cells. Both IFN-beta- and IFN-gamma-inducible gene expression were enhanced via a modulation of the transcriptional factor IFN-stimulated gene factors-3 and GAF binding to respective cognate regulatory elements. STAT1 was undetectable in these cells prior to RA treatment. RA increased the levels of this crucial regulator, thereby restoring IFN responses. Thus, RA augmentation of STAT1 may be an early step in the cooperative anti-tumor effects of IFN and RA.

Abstract
We investigated the effect of all-trans retinoic acid (ATRA) alone and in combination with interferon-alpha (IFN-alpha) on the granulocyte-macrophage (GM) colony formation of peripheral blood progenitors isolated from patients with chronic myeloid leukemia (CML) (n = 12) or other myeloproliferative disorders (n = 10) as well as from healthy controls (n = 7). The ATRA or IFN-alpha alone inhibited slightly, but not significantly, the GM colony growth in CML. Granulocyte-macrophage colony formation decreased significantly (P<0.05) when ATRA and IFN-alpha were combined (114 +/- 96 versus 74 +/- 53 colonies/10(4) mononuclear cells). The combination did not have any inhibitory effect on the other MPDs. In healthy controls, ATRA or IFN-alpha alone or their combination stimulated GM colony growth, the increase being from 22 +/- 9 to 39 +/- 16 colonies for ATRA (P<0.05), up to 47 +/- 12 colonies for IFN-alpha (P<0.05) and up to 50 +/- 19 colonies for the combination (P<0.05). In conclusion, ATRA combined with IFN-alpha inhibits GM colony growth in CML. This combination may be worth testing clinically as a treatment of CML.

Abstract
As a single agent, interferon-alpha (IFN-alpha) can induce remissions, mostly partial, in a large fraction of patients with indolent lymphomas, including the low grade B-cell lymphomas and cutaneous T-cell lymphoma. In aggressive lymphomas, IFN has minimal activity, and in Hodgkin's disease the limited available experience suggests only modest activity. In indolent B-cell lymphomas, IFN has been integrated with chemotherapy in several large trials: the majority of these trials indicate a favorable impact on failure-free survival; a survival benefit of IFN has been reported by the French-Belgian group. Updated results are now available from a previously reported trial from the MD Anderson Cancer Center that also indicate an apparent survival benefit when IFN is used in conjunction with chemotherapy in patients with indolent B-cell lymphoma.

Abstract
Retinoic acid is apparently required for the normal differentiation of reproductive epithelium. Cellular abnormalities in retinoid homeostasis could be a factor in the development of endometrial malignancy. We have thus investigated the expression of nuclear retinoic acid receptors (RARs and RXRs) and cellular binding proteins for retinol (CRBP) and retinoic acid (CRABP) in endometrial adenocarcinoma of the endometrioid histological subtype. Ten grade I, II grade 2 and 10 grade 3 tumour samples, as well as 4 samples of severe atypical precancerous endometrial hyperplasia, were studied. No significant difference in expression of RAR-beta was detected in tumour samples compared with normal epithelial cells. RAR-gamma was significantly elevated in grade 1 and 2 carcinomas, but this may be due to greater stromal cell involvement in these lower grade tumours. There was significant elevation of CRBP I mRNA in tumour samples. Furthermore, although undetectable in normal endometrial epithelium, CRABP I was expressed in 3/II grade 2 and 9/10 grade 3 carcinomas, with expression being significantly higher where the primary tumour had invaded more than 50% of the total myometrial thickness. Analysis of 2 epithelial-like endometrial adenocarcinoma cell lines supported the idea that CRABP I expression is characteristic of poorly differentiated endometrial adenocarcinoma. Our data suggest that alterations in mechanisms of retinoid homeostasis are a feature of endometrial adenocarcinoma and may contribute to the severity of disease.

Abstract
Standard cytotoxic regimens have failed to prolong survival in patients with recurrent cervical cancer; therefore, new agents or combinations of agents are necessary to improve outcome. Cisplatin and 5-fluorouracil are one of the most active regimens currently available for recurrent cervical cancer. Interferon-alpha and potentiate the in vitro and in vivo activity of both agents. Therefore, we sought to define the feasibility and activity of adding interferon-alpha to the cisplatin-5-fluorouracil regimen. Patients with histologically proven recurrent cervical carcinoma received interferon-alpha (5 x 10(6) units/m2/day for 5 days) combined with cisplatin (75 mg/m2 on day 1) plus 5-fluorouracil (500 mg/m2/day for 5 days) in recurrent cervical cancer. Twenty-six patients were included in this study and received a total of 95 courses of therapy. All 26 had prior radiotherapy and five had prior chemotherapy. This regimen was relatively well tolerated as toxicity was comparable to that of cisplatin plus 5-fluorouracil alone. Major response occurred in 8 patients (31%) and 5 (19%) had complete responses. The median response duration was 6 months (range, 2-34 months) and the median survival duration was 9 months (range, 2-38 months). The addition of interferon-alpha to cisplatin plus 5-fluorouracil is feasible. Further studies will be necessary to determine if the addition of interferon-alpha to this regimen is superior to cisplatin plus 5-fluorouracil alone.
