Tissues from human benign prostatic hyperplasia [BPH] were collected from twelve patients undergoing routine transurethral resection of the prostate to relieve urine out-flow obstruction. Viable epithelial organoids were obtained after enzymatic digestion of the tissue. Primary cultures of epithelium were successfully maintained on collagen gel for up to 21 days. Immunocytochemical staining revealed that there was no expression of either desmin or vimentin in these cells; however, the anticytokeratin antibodies LP-34 (cytokeratins 4, 5, 6, 10, 13, 16, 17 and 18), LE-61 (cytokeratin 18) and CAM 5.2 (cytokeratins 7 and 8) all showed positive responses, indicating the epithelial nature of the cells. Cell growth was significantly increased in the presence of 3 x 10(-10) M testosterone propionate [TP] in the culture medium. The presence of the non-steroidal anti-androgens, Flutamide and Hydroxy-Flutamide [Flu-OH], in the concentration range 1.0-0.001 micrograms per ml of medium inhibited the growth in the presence of androgens in a dose-dependent manner. The anti-androgens failed to affect cell growth in the absence of TP. In view of these preliminary findings, it is postulated that the antiandrogens might be acting either by displacing the androgen from its receptor or alternately by inhibiting the activity of prostatic 5 alpha-reductase.

Flutamide (4'-nitro-3'-trifluoromethylisobutyranilide) has a pronounced effect on the delta 4-3-ketosteroid 5-reductases of cortisol in man. The urinary metabolites isolated following 4-14C-cortisol administration to men with prostatic cancer treated with flutamide indicate decreased activity of the 5 beta-reductase with increased activity of 5 alpha-reductase. The alternate pathway of cortisol metabolism to the cortols and cortolones via Reichstein's substances epi E and Epi U is enhanced.

Testicular androgens are known to influence not only the secretion but also the bioactivity and molecular composition of pituitary FSH. In the present study, we investigated the effects of chronic androgen blockade and castration on the molecular heterogeneity of the gonadotrophin. Groups of male adult rats (five animals per group) received one of the following treatments: vehicle, the non-steroidal anti-androgens casodex (20 mg/kg per day) or flutamide (20 mg/kg per day), or castration. After 8 weeks, the animals were killed and individual pituitary homogenates fractionated by isoelectric focusing (IEF) on sucrose density gradients in the pH range 2.5-8. FSH was measured by radioimmunoassay (RIA) in the individual fractions and by invitro bioassay (Sertoli cell aromatase bioassay) in pools of fractions which were combined according to pH intervals of 0.5 units. Bioactive and immunoreactive FSH were also measured in sera and unfractionated pituitary extracts. Testosterone and inhibin were assayed in sera by RIA. A significant increase in serum immunoreactive and bioactive FSH was demonstrated in flutamide-treated and castrated animals, whereas the pituitary content of bioactive FSH remained unchanged in the four groups. Serum testosterone and inhibin were undetectable in castrated animals and significantly increased in those treated with flutamide. By RIA, the IEF profiles of the flutamide-treated and castrated rats showed a significant reduction of the FSH isoforms with 3.5 < pI < 4, with a significant increase in the isoforms with pI > 4 only in the castrated group.(ABSTRACT TRUNCATED AT 250 WORDS)

Flutamide, a widely used nonsteroidal antiandrogen drug for the treatment of prostate cancer, has been associated with rare incidences of hepatotoxicity in patients. It is believed that bioactivation of flutamide and subsequent covalent binding to cellular proteins is responsible for its toxicity. A novel N-S glutathione adduct has been identified in a previous bioactivation study of flutamide (Kang et al., 2007). Due to the extensive first pass metabolism, flutamide metabolites such as 2-hydroxyflutamide and 4-nitro-3-(trifluoromethyl)phenylamine (Flu-1) have achieved plasma concentrations higher than the parent in prostate cancer patients. In vitro studies in human liver microsomes were conducted to probe the cytochrome P450 (P450)-mediated bioactivation of flutamide metabolites and identify the possible reactive species using reduced glutathione (GSH) as a trapping agent. Several GSH adducts (G1, Flu-1-G1, Flu-1-G2, Flu-6-Gs) derived from the metabolites of flutamide were identified and characterized. A comprehensive bioactivation mechanism was proposed to account for the formation of the observed GSH adducts. Of interest were the formation of a reactive intermediate by the desaturation of the isopropyl group of M5 and the unusual bioactivation of Flu-1. Studies using recombinant P450s suggested that the major P450 isozymes involved in the bioactivation of flutamide and its metabolites were CYP1A2, CYP3A4, and CYP2C19. These findings suggested that, in addition to the direct bioactivation of flutamide, the metabolites of flutamide could also be bioactivated and contribute to flutamide-induced hepatotoxicity.

Female Zucker diabetic rats (FZDR) aged 5-6 weeks and from the same litter were divided into 2 groups (n = 6-8 each). The experimental group received the androgen receptor blocker flutamide, dissolved in alcohol and added to their drinking water (500 mL) at 20 mg/rat/week. The control FZDR received only the alcohol vehicle added to the same volume of drinking water. Both FZDR groups were treated for 3 months before undergoing the hemodynamic studies. A sex comparison control group of male Zucker diabetic rats (MZDR), also aged 5-6 weeks, was studied, following same protocol. Mean arterial pressure (MAP) and renal cortical blood flow (RCF) response to phenylephrine, acetylcholine, TXA2-mimetic U46619, endothelin-1 (ET-1), angiotensin II, and L-NG-nitro arginine methyl ester were studied. Furthermore, the role of protein kinase C in the responses was assessed using phorbol-12,13 dibutyrate 10(-4) M. The impact of flutamide on body weights and blood glucose of the rats were also determined.

Many pesticides possess hormonal activity and have thus been classified as endocrine disruptors. Pyrethroids are commonly used pesticides worldwide, but little has been done to characterize their antiandrogenic activity potential. We tested three frequently encountered pyrethroids (fenvalerate, cypermethrin, permethrin) and their metabolite 3-phenoxybenzoic acid (3-PBA) for antiandrogenic and androgenic activity using a human androgen receptor (AR) mediated luciferase reporter gene assay in CV-1 African green monkey kidney cell. The assay displayed appropriate response to the known AR agonist 5alpha-dihydrotestosterone and AR antagonist nilutamide and flutamide. At 0.1mM, all the three tested pyrethroids significantly suppressed the luciferase expression. Further, their metabolite 3-PBA also showed antagonist activity. None of the test chemicals showed androgenic activity. Through the antiandrogenic pathways, exposure to certain pyrethroids may contribute to the damage of reproductive system. In conclusion, pyrethroid pesticides can act as antiandrogen in vitro, and metabolizing to 3-PBA cannot eliminate the antagonist activity. This result provides useful information for risk assessment of pyrethroid pesticides.

Stage pT0 following prolonged neoadjuvant endocrine therapy (PPNET) of prostate cancer is of great clinical interest, because this finding suggests maximum tumor damage. Therefore pT0 patients are expected to have an extremely favorable PSA progression rate. The purpose of this study was to assess whether the PSA progression rate of pT0 patients after PPNET is lower than that of non-pT0 patients after PPNET.

Sixty-eight patients who underwent radical prostatectomy without or after neo-adjuvant hormonotherapy for B2 or C stage prostate cancer were evaluated as concerned to the ease of the surgical procedure. Although it is difficult to assess this parameter, we experienced more difficulties and blood loss was higher in patients who had preoperative hormonal deprivation. Ongoing randomized trials could demonstrate an oncological benefit of neo-adjuvant hormonotherapy before radical prostatectomy. This eventual benefit will have to be balanced against an increased surgical difficulty.

310 patients were randomized to treatment by FLU (250 mg t.i.d. p.o.) or CPA (100 mg t.i.d. p.o.). Of the 310 patients, 12 (3.9%) were ineligible. The baseline characteristics of the two groups were similar except for age which was significantly younger in the CPA group and for the presence of soft tissue metastases which were absent in the FLU group and present in 6 patients in the CPA group. The median follow-up was 8.6 years, 245 patients died, 158 (64.5%) of prostate cancer. There was no significant difference between the treatment arms with respect to overall survival, specific survival nor time to progression. Side effect profiles were studied and found to be more favourable for CPA overall and in particular with respect to gynecomastia, diarrhea and nausea.

Physical examination at the time of enrollment was unremarkable. His PSA declined to below the limits of detection after this maneuver and at last follow-up had been maintained there for more than 46 months. In 1995, the patient underwent a repeat biopsy of the prostate and all six tissue cores were negative for carcinoma. At last follow-up in December 1996, the patient had no evidence of disease and was being followed routinely; however, the authors were continuing treatment with testicular suppression (leuprolide) plus hydrocortisone.

To evaluate the usefulness of total androgen blockade (TAB) therapy, we retrospectively studied 45 patients with prostate cancer who received TAB therapy as the first-line treatment. The clinical stage was A2 in 1 patient, B1 in 10, B2 in 9, C in 6, D1 in 3 and D2 in 16. Seven, 25 and 13 patients had well, moderately and poorly differentiated adenocarcinomas, respectively. The patients were placed on 1 of 3 TAB regimens: Luteinizing hormone-releasing hormone (LH-RH) agonist and flutamide (group 1), LH-RH agonist and chlormadinone acetate (group 2) and a surgical castration and flutamide (or chlormadinone acetate) (group 3). The therapeutic effect was evaluated at 12 weeks according to the response criteria in the general rules for clinical and pathological studies on prostatic cancer. The overall response was partial response (PR) in 35 patients (77.8%), no change (NC) in 6 (13.3%) and progressive disease (PD) in 4 (8.9%). PR was obtained in 81.3, 79.2 and 60% of the patients in groups 1, 2 and 3, respectively. One patient with PD responded briefly to flutamide withdrawal. None of the patients developed any severe adverse effects. In conclusion, the first-line TAB therapy is effective for prostate cancer with a lower risk than estrogens. Relapsed cases should be followed for flutamide withdrawal syndrome during TAB therapy.

Experiment 1: Treatment with flutamide resulted in a 36 percent (26/72) incidence of undescended testes (UDT), and a 43 percent (31/72) incidence of abnormal epididymides. Rats treated simultaneously with flutamide plus EGF had a reduced incidence of UDT (14%, 6/42) and epididymal anomalies (19%, 8/42); p < 0.01. Experiment 2: The absence of maternal EGF resulted in a significant incidence of cryptorchidism in 11/50 (22%) testes, and epididymal anomalies in 19/50 (38%); p < 0.01.

We designed and synthesized novel pyrrole-2-carboxamide derivatives as androgen antagonists. Compounds 10 and 13 bearing benzylamine or aniline at the 4-position of the pyrrole ring showed moderate androgen antagonistic activity, and inhibited the androgen-dependent growth of Shionogi carcinoma cells (SC-3). Study of the structure-activity relationships of compound 13 led to a potent androgen antagonist 36, which has higher affinity than flutamide (4) for androgen nuclear receptor (AR). Thus, pyrrole-2-carboxamide is a new scaffold for developing AR antagonists.

We have investigated the role of endothelium-derived relaxing factors, K(+) channels and steroid receptors in vasorelaxation to testosterone in the rat aorta. Testosterone (1 nM-mM) caused acute concentration-dependent vasorelaxation. Both indomethacin (10 microM) and flurbiprofen (10 microM) uncovered relaxant responses to testosterone. The action of indomethacin was inhibited by endothelial removal. N(G)-nitro-L-arginine methyl ester (L-NAME, 300 microM) had no effects on testosterone-induced responses. In the presence of indomethacin, the vasorelaxant potency of testosterone was reduced by depolarization with 60 mM KCl or charybdotoxin (100 nM), but not by glibenclamide (10 microM), 4-aminopyridine (1 mM) or barium chloride (30 microM). The responses to testosterone were not inhibited by flutamide (10 microM) or mifepristone (30 microM). Pre-treatment of the aorta with testosterone (100 microM) inhibited CaCl(2)-induced contraction. In the present study, we have demonstrated that testosterone causes acute vasorelaxations, which are modulated via endothelium-derived prostanoids. The responses uncovered by cyclooxygenase inhibitors are due to the activation of K(Ca) channels, while at higher concentrations, testosterone inhibits Ca(2+) influx.

Liver microsomes were prepared from male or female rats. Protein concentration and total cytochrome P450 content were determined. Incubation mixture included liver microsomes (1.0 nmol.L-1), reduced form of nicotinamide adenine dinucleotide phosphate (NADPH, 0.1 nmol.L-1), CYP1A2 (1:400) and flutamide (2 mg.L-1). The incubation time was 30 min. The concentration of flutamide and its major metabolite 2-hydroxyflutamide were analyzed by reverse high-performance liquid chromatography. The mobile phase was a mixture of methanol-acetonitrile-water-diethylether (40:20:35:1) with methyltestosterone as internal standard. The detection wavelength was 234 nm. The reaction mixture was extracted with acetic buy eulexin ether 4 mL. Sex-difference on flutamide metabolism was expressed as the difference between the concentration ratio of 2-hydroxyflutamide to flutamide in male and female rat liver microsomes.

Steroid hormones may act through a rapid mechanism that does not require an intracellular steroid receptor and its effects on gene expression. In this study we have analysed this so-called non-genomic effect of testosterone on social anxiety in rats of both sexes using androgen and oestrogen receptor blockers. Male rats were buy eulexin divided into four groups: SHAM-CTRL (a sham operated group treated with oil as vehicle, n=10), SHAM-TST (a sham operated group treated with testosterone at a dose of 1 mg/kg, n=10), GDX-CTRL (a castrated group treated with oil, n=10) and GDX-TST (a castrated group treated with testosterone at a dose of 1 mg/kg, n=10). Female rats were divided into two groups: OVX-CTRL (an ovariectomized group treated with oil, n=10) and OVX-TST (an ovariectomized group treated with testosterone, n=10). The intracellular androgen receptor was blocked with flutamide and both intracellular oestrogen receptors were blocked with tamoxifen (a selective oestrogen receptor modulator). Rats were tested one hour after oil or testosterone administration in the social interaction test. Although the concentration of testosterone was higher in testosterone groups, no significant difference in social interaction was observed between the groups. In summary, in this first study focusing on the non-genomic effects of testosterone on social interaction no rapid effects of testosterone in adult rats were found. Further studies should analyse potential non-genomic effects of testosterone on other forms of social behaviour.

The purpose of this study was to determine the effects of 6-amino-2-[2-(4-tert-butyl-phenoxy)-ethylsulfonyl]-1H-pyrimidine-4-one (DL3), a novel synthetic compound with small-molecule drug properties, on androgen-regulated gene expression and cell growth in human prostate cancer cells. LNCaP, 22Rv1, and LAPC-4 cells were used in the studies. Expression of prostate-specific antigen (PSA) and androgen receptor (AR) was determined by ELISA, Western blotting, real-time reverse transcription-PCR, nuclear run-on, and/or promoter luciferase reporter assays. Effects of DL3 on cell growth were determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide staining. DL3 inhibited dihydrotestosterone (DHT)-induced PSA expression in a dose-dependent fashion. The inhibitory effects of DL3 were more potent than those of flutamide, nilutamide, and bicalutamide. Moreover, DL3 blocked the stimulatory effects of nilutamide on PSA expression in LNCaP cells. Unlike the three classic antiandrogens, DL3 did not show intrinsic AR agonist activity. Nuclear run-on and PSA promoter reporter assays revealed that DL3 blocked DHT-induced PSA gene transcription. Consistent with its effects on PSA expression, DL3 inhibited DHT-stimulated cell growth with a potency significantly superior to flutamide, nilutamide, or bicalutamide. Furthermore, cells resistant to flutamide or nilutamide were as susceptible as their parental counterparts to the inhibitory effects buy eulexin of DL3 on both PSA expression and cell growth. DL3 did not inhibit AR nuclear localization and the NH(2)- and COOH-terminal interaction of AR induced by DHT. These data show that DL3 is a novel inhibitor of the AR signaling axis and a potentially potent therapeutic agent for the management of advanced human prostate cancer.

In this work, we examined the metabolism of the carbamate insecticides methiocarb and carbaryl buy eulexin by rat liver microsomes and plasma, and its effect on their endocrine-disrupting activities. Methiocarb and carbaryl were not enzymatically hydrolyzed by rat liver microsomes, but were hydrolyzed by rat plasma, mainly to methylthio-3,5-xylenol (MX) and 1-naphthol, respectively. When methiocarb was incubated with rat liver microsomes in the presence of NADPH, methiocarb sulfoxide was formed. The hydrolysis product, MX, was also oxidized to the sulfoxide, 3,5-dimethyl-4-(methylsulfinyl)phenol (SP), by rat liver microsomes in the presence of NADPH. These oxidase activities were catalyzed by cytochrome P450 and flavin-containing monooxygenase. Methiocarb and carbaryl both exhibited estrogen receptor α (ERα) and ERβ agonistic activity. MX and 1-naphthol showed similar activities, but methiocarb sulfoxide and SP showed markedly decreased activities. On the other hand, methiocarb and carbaryl exhibited potent antiandrogenic activity in the concentration range of 1×10(-6)-3×10(-5) M. Their hydrolysis products, MX, and 1-naphthol also showed high activity, equivalent to that of flutamide. However, methiocarb sulfoxide and SP showed relatively low activity. Thus, hydrolysis of methiocarb and carbaryl and oxidation of methiocarb to the sulfoxide markedly modified the estrogenic and antiandrogenic activities of methiocarb and carbaryl.

Androgen receptor (AR) antagonists are part of the standard of care for prostate buy eulexin cancer. Despite the almost inevitable development of resistance in prostate tumors to AR antagonists, no new AR antagonists have been approved for over a decade. Treatment failure is due in part to mutations that increase activity of AR in response to lower ligand concentrations as well as to mutations that result in AR response to a broader range of ligands. The failure to discover new AR antagonists has occurred in the face of continued research; to enable progress, a clear understanding of the reasons for failure is required.

Arm C consisted of patients with Stage D1 (positive pelvic lymph nodes) who received the same regimen as Arm B with the addition of 45 Gy to the pelvic lymphatics. PSA determination and biopsy were performed before, during, and after treatment. The American Society for Therapeutic Radiology and Oncology consensus definition (three consecutive rises in PSA level) was used to denote PSA failure.

Treatment outcome in congenital adrenal hyperplasia is often suboptimal due to hyperandrogenism, treatment-induced hypercortisolism, or both. As a new approach, we hypothesized that the effects of androgen could be blocked by an antiandrogen (flutamide) and an inhibitor androgen to estrogen conversion (testolactone), thus allowing the hydrocortisone dose to be reduced. We conducted a short term pilot study in 12 children with congenital adrenal hyperplasia in a randomised cross-over open design to determine whether flutamide, testolactone, reduced hydrocortisone dose, and fludrocortisone are more effective than hydrocortisone and fludrocortisone treatment in normalizing linear growth, weight gain, and bone maturation. Each regimen was administered for 6 months, with a 3-month washout period, consisting of hydrocortisone and fludrocortisone treatment, between regimens. Compared to hydrocortisone and fludrocortisone treatment, the regimen of flutamide, testolactone, reduced hydrocortisone dose (from 12.9 to 7.9 mg/m2 day), and fludrocortisone produced an increase in plasma 17-hydroxyprogesterone levels (P < 0.05) and a decline in urinary cortisol (P < 0.01), linear growth rate (-0.9 +/- 0.5 vs. 1.4 +/- 0.6 SD U; P = 0.003), weight velocity (-0.80 +/- 4.0 vs 0.6 +/- 0.4 SD U; P = 0.01), and bone maturation (0.6 +/- 0.6 vs. 1.4 +/- 0.9 yr bone age/yr chronological age; P = 0.02). Although buy eulexin no important adverse effects were observed, the known potential for flutamide-induced hepatotoxicity made frequent monitoring essential. We conclude that the regimen of flutamide, testolactone, reduced hydrocortisone does, and fludrocortisone improve the short term control of growth and bone maturation in children with congenital adrenal hyperplasia. Long term studies are required to determine whether this approach can improve these children's growth and development.

Human serum albumin (HSA) is the most abundant protein in plasma with a high ligand-binding capacity. This capacity impacts the pharmacokinetic properties of therapeutic drugs. In the present study, the binding properties of flutamide to HSA at different temperatures, pHs and percentages of HSA were investigated. Thermodynamic parameters were also determined to describe the nature of binding interaction. A modified ultrafiltration method was used for accurate determination of flutamide-HSA parameters. Ultra filtrate samples containing free flutamide were extracted and analyzed by developed HPLC-UV method. Analysis of binding data was performed in terms of Scatchard, Klotz and Hill plots. Kinetic parameters (n, Ka) were found to be affected by temperature, pH and HSA concentration. However, flutamide-HSA-binding level did not show significant differences under different experimental conditions. The negative value of Gibbs free energy (ΔG) indicated that the binding was spontaneous. Moreover, the negative value for enthalpy and entropy changes suggested that hydrogen bonding and van der Waals forces played major role in the binding of flutamide to HSA. The results suggested a positive cooperation behavior of buy eulexin flutamide-HSA-binding that was affected by pH, temperature and percentage of HSA.

We analyzed whether aromatase is expressed in human myometrial microvascular endothelial cells (HMMECs) and whether Paxil Reviews it affects proliferation and converts androgens to estrogens. In addition, we aimed to define whether or not T could have a direct capability to affect HMMEC proliferation.

Survival data were Effexor Generic Name available from a previously published controlled trial that had evaluated the efficacy and tolerability of two antiandrogens, bicalutamide and flutamide, each combined with a monthly depot preparation of leuprolide or goserelin, in 813 patients with Stage D2 prostate cancer. Cox's proportional hazards regression model assessed the relative effects of the length of combined androgen blockade (CAB) therapy on survival. This analysis was repeated in the subset of patients who lived at least 2 years beyond the date of randomization. Data were obtained at a median follow-up of 160 weeks.

Androgen administration to castrated individuals was purported to decrease activity in the serotonin system. However, we found that androgen administration to castrated male macaques increased fenfluramine-induced serotonin release as reflected by increased prolactin secretion. In this study, we sought to define the effects of androgens and aromatase inhibition on serotonin-related gene expression in the dorsal raphe, as well as serotonergic innervation of the LC. Male Japanese macaques (Macaca fuscata) were castrated for 5-7 months and then treated for 3 months with (1) placebo, (2) testosterone (T), (3) dihydrotestosterone (DHT; non-aromatizable androgen) and ATD (steroidal aromatase inhibitor), or (4) Flutamide (FLUT; androgen antagonist) and ATD (n=5/group). This study reports the expression of serotonin-related genes: tryptophan hydroxylase 2 (TPH2), serotonin reuptake transporter (SERT) and the serotonin 1A autoreceptor (5HT1A) using digoxigenin-ISH and image analysis. To examine the production of serotonin and the serotonergic innervation of a target area Diovan Tablet 80mg underlying arousal and vigilance, we measured the serotonin axon density entering the LC with ICC and image analysis. TPH2 and SERT expression were significantly elevated in T- and DHT + ATD-treated groups over placebo- and FLUT + ATD-treated groups in the dorsal raphe (p < 0.007). There was no difference in 5HT1A expression between the groups. There was a significant decrease in the pixel area of serotonin axons and in the number of varicosities in the LC across the treatment groups with T > placebo > DHT + ATD = FLUT + ATD treatments. Comparatively, T- and DHT + ATD-treated groups had elevated TPH2 and SERT gene expression, but the DHT + ATD group had markedly suppressed serotonin axon density relative to the T-treated group. Further comparison with previously published data indicated that TPH2 and SERT expression reflected yawning and basal prolactin secretion. The serotonin axon density in the LC agreed with the area under the fenfluramine-stimulated prolactin curve, providing a morphological basis for the pharmacological results. This suggested that androgen activity increased TPH2 and SERT gene expression but, aromatase activity, and neural production of estradiol (E), may subserve axonal serotonin and determination of the compartment acted upon by fenfluramine. In summary, androgens stimulated serotonin-related gene expression, but aromatase inhibition dissociated gene expression from the serotonin innervation of the LC terminal field and fenfluramine-stimulated prolactin secretion.

Prostate cancer sometimes metastasizes, especially to bone, which may cause pain, fractures and spinal cord compression. What are the best first-line treatment options for patients with metastatic prostate cancer? To answer this question, we conducted a review of the literature, using the standard Prescrire methodology. Suppressing androgen secretion by surgically removing the testicles (orchiectomy) or by administering a gonadorelin agonist relieves the pain associated with bone metastases in about 80% of patients. This treatment has a clear impact on symptoms, despite the lack of clinical trials versus placebo or no treatment. Its impact on overall survival is uncertain. In terms of survival, goserelin therapy appears to have similar efficacy to orchiectomy. The efficacy of other gonadorelin agonists is less well documented. Degarelix, a gonadorelin antagonist, does not appear to provide a therapeutic advantage over gonadorelin agonist. In 2012, oestrogen should not be used in the treatment of metastatic prostate cancer, because of its cardiovascular adverse effects. Antiandrogen monotherapy, preferably with flutamide, appears to be less beneficial Bactrim Dosage than orchiectomy in terms of survival. Overall, adverse effects are more frequent with nonsteroidal antiandrogens than with gonadorelin agonists, but sexual dysfunction is less frequent. Cyproterone, a steroidal antiandrogen, seems to have fewer adverse effects leading to treatment discontinuation than nonsteroidal antiandrogens. There is no firm evidence that starting hormonal therapy before metastases become symptomatic is beneficial. When symptoms have disappeared and the PSA level is low, one option is to temporarily interrupt gonadorelin agonist therapy if it is poorly tolerated, even though this may shorten survival by a few months. The addition of a nonsteroidal antiandrogen to androgen suppression therapy slightly improves 5-year survival, preventing about 3 deaths per 100 patients, but at a cost of additional adverse effects. First-line hormonal treatments are initially very effective in relieving symptoms of metastatic prostate cancer. Our analysis of the available data suggests that the best treatment option is androgen suppression with goserelin. Flutamide monotherapy is an alternative for some patients.

We report that growth of LNCaP human prostate cancer cells is significantly stimulated (up to 120% above control) by physiological estradiol (E2) concentrations. This growth increase appears to be comparable to that induced by either testosterone or dihydrotestosterone, as also reported by others. This paper presents novel illustrative evidence for estrogen-binding proteins and messenger RNA transcripts in LNCaP cells. In fact, 1) the reverse transcriptase-polymerase chain reaction system documented normal messenger RNA for estrogen receptors (ER); 2) the radioligand binding assay allowed the detection of high affinity, reduced capacity binding sites in both soluble and nuclear cell fractions; and 3) the immunocytochemical analysis showed a consistently intensive staining for both ER and progesterone receptors. Compared to other human estrogen-responsive mammary cancer cells, MCF7 and ZR75-1, ER expression in LNCaP cells was not significantly lower, as shown by levels of the ER transcripts, number of sites per cell, or femtomoles per mg DNA as well as the percentage and intensity of immunocytochemical staining. A relative estimate of ER expression obtained by matching LNCaP with another human prostate cancer cell line, PC3, always displayed significantly and consistently higher levels in LNCaP cells. The detection of relatively high type I ER content in either cell compartment of LNCaP cells was paralleled by a highly intensive staining for progesterone receptors. In addition, evidence that the synthetic androgen R1881 did Mobic Pain Medicine not compete for type I binding of E2 and that any E2-induced growth was completely reversed by the pure antiestrogen ICI-182,780, but unaffected by the antiandrogen Casodex, clearly suggests that the biological response of LNCaP cells to E2 is mediated via its own receptor.

Flutamide is a nonsteroidal antiandrogen drug used in the treatment of prostatic cancer. Hepatotoxic reactions due to flutamide have been reported with an incidence ranging from 1% to 5%. These reactions are usually reversible upon withdrawal of the drug but can occasionally be life-threatening. The mechanism of flutamide-associated hepatotoxicity is not well established. We report a case of a 69-year-old man with prostatic carcinoma in whom flutamide induced an acute hepatitis which resolved completely soon after drug withdrawal. In this patient, we have studied the possible involvement of an immunological mechanism in causing flutamide hepatitis by investigating the presence of circulating antibodies directed against reactive metabolites of flutamide bound to liver proteins with enzyme-linked immunosorbent assay technique. Although, in the present case, we have failed to detect IgG reacting Rulide Medication Dosage with rat liver microsomes incubated in vitro with flutamide, this does not completely rule out the possibility of an immunological involvement in flutamide hepatotoxicity. The possibility of severe flutamide-related injury, independently of the underlying pathogenic mechanism, strongly suggests the need for careful monitoring of liver enzymes in patients taking this drug.
