Finasteride and epristeride both inhibit 5α-reductase with high potency via competitive and non-competitive mechanism, respectively. A new hybrid of finasteride and epristeride was designed as a new 5α-reductase inhibitor based on combination principles in medicinal chemistry. Human 5β-reductase was chosen as a plausible surrogate of 5α-reductase type II and the results indicate that although the hybrid compound possesses the main bulk of epristeride, its inhibitory mechanism is same as of finasteride. The hybrid turned out to be a potent 5α-reductase inhibitor in low IC(50) ranges.

Finasteride, a 5 alpha-reductase inhibitor, was administered to normal male volunteers in a blinded placebo-controlled study at daily oral doses of 25, 50, and 100 mg for 11 days (part 1) and daily oral doses of 0.04, 0.12, 0.2, and 1.0 mg for 14 days (part 2). Results from part 1 showed a significant reduction in dihydrotestosterone (DHT) at all doses and a significant increase in both testosterone (T) and delta 4-androstenedione at the 50- and 100-mg doses. No change was seen in LH, FSH, cortisol, or estradiol levels. Serum lipids, including total cholesterol, low density lipoprotein, high density lipoprotein, and triglycerides were not affected by treatment. Results from part 2 again showed significant reduction in DHT at all doses. DHT levels returned to pretreatment values within 14 days of discontinuing treatment. Significant increases in T were observed only in the 1.0 mg group and only during the first 8 days of treatment. The T/DHT ratio increased with all doses and returned to baseline when drug was discontinued. The DHT metabolites and androstanediol glucuronide and androsterone glucuronide were significantly reduced at all doses. There were no significant adverse experiences reported during part 1 or 2. In conclusion, finasteride is well tolerated by normal volunteers and results in significant suppression of serum DHT at all doses tested.

Although in the general population, obtaining a cancer diagnosis is improved by assessing prostate volume and increasing the number of biopsy cores, neither steps are required in men receiving finasteride. Obtaining fewer biopsy cores in men receiving finasteride preserves biopsy sensitivity and will likely reduce cost and morbidity.

Palmitoylethanolamide (PEA) regulates many pathophysiological processes in the central nervous system, including pain perception, convulsions and neurotoxicity, and increasing evidence points to its neuroprotective action. In the present study, we report that PEA, acting as a ligand of peroxisome-proliferator activated receptor (PPAR)-α, might regulate neurosteroidogenesis in astrocytes, which, similar to other glial cells and neurones, have the enzymatic machinery for neurosteroid de novo synthesis. Accordingly, we used the C6 glioma cell line and primary murine astrocytes. In the mitochondrial fraction from cells stimulated with PEA, we demonstrated an increase in steroidogenic acute regulatory protein (StAR) and cytochrome P450 enzyme (P450scc) expression, both comprising proteins considered to be involved in crucial steps of neurosteroid formation. The effects of PEA were completely blunted by GW6471, a selective PPAR-α antagonist, or by PPAR-α silencing by RNA interference. Accordingly, allopregnanolone (ALLO) levels were increased in supernatant of PEA-treated astrocytes, as revealed by gas chromatography-mass spectrometry, and this effect was inhibited by GW6471. Moreover, PEA showed a protective effect, reducing malondialdehyde formation in cells treated with l-buthionine-(S,R)-sulfoximine, a glutathione depletor and, interestingly, the effect of PEA was partially inhibited by finasteride, a 5α-reductase inhibitor. A similar profile of activity was demonstrated by ALLO and the lack of an additive effect with PEA suggests that the reduction of oxidative stress by PEA is mediated through ALLO synthesis. The present study provides evidence indicating the involvement of the saturated acylethanolamide PEA in ALLO synthesis through PPAR-α in astrocytes and explores the antioxidative activity of this molecule, confirming its homeostatic and protective role both under physiological and pathological conditions.

The lack of an association in our study suggests that the development of breast cancer should not influence the prescribing of 5α-reductase inhibitor therapy.

We have discovered that 17beta-[N,N-(diethyl)carbamoyl]-6-azaandrost-4-en-3-one is a time-dependent inhibitor of type II 5alpha-reductase, as is the drug finasteride. Unlike finasteride, the 6-aza-steroid is not a time-dependent inhibitor of type I 5 alpha-reductase. Finasteride inhibition of type II enzyme proceeds in a two-step mechanism. At pH 6 and 37 degrees C, an initial finasteride-reductase complex is formed with a K(i)(app) of 11.9 +/- 4.1 nM. In a second step, an irreversible complex is formed with a rate constant of inactivation of 0.09 +/- 0.01 s(-1). In contrast, the 6-aza-steroid is a reversible inhibitor. From the results of a simplified mathematical analysis, based on the rapid equilibrium approximation, the inhibitor and the enzyme form an initial complex with a K(i) of 6.8 +/- 0.2 nM. The reversible formation of a final complex, with an overall K(i) of 0.07 +/- 0.02 nM, is characterized by a first-order isomerization rate constant 0.0035 +/- 0.0001 s(-1) for the forward step and 0.00025 +/- 0.00006 s(-1) for the backward step. All rate constants for the two-step mechanism were obtained by using a general numerical integration method. The best fit values for the association and dissociation rate constants were 5.0 microM(-1) s(-1) and 0.033 +/- 0.008 s(-1), respectively, and the isomerization rate constants were 0.0035 +/- 0.007 s(-1) and 0.000076 +/- 0.000019 s(-1). These values correspond to an initial K(i) of 6.5 nM and an overall dissociation constant of 0.14 nM. The data presented here show that both finasteride and the 6-aza-steroid analogs are potent against type II 5alpha-reductase, although their mechanisms of inhibition are different.

Baseline patient characteristics were generally comparable between responders and non-responders. The proportion of patients with an International Prostate Symptom Score improvement ≥3 points with tadalafil/finasteride and placebo/finasteride, respectively, at week 4 was 57.0% and 47.9% (OR 1.45, 95% confidence interval 1.07-1.97), at week 12 was 68.8% and 60.7% (OR 1.48, 95% confidence interval 1.07-2.05) and at week 26 was 71.4% and 70.2% (OR 1.14, 95% confidence interval 0.81-1.61); for IPSS change ≥25%, the corresponding proportions were 44.8% and 32.9% (OR 1.66, 95% confidence interval 1.21-2.28), 55.5% and 51.9% (OR 1.18, 95% confidence interval 0.87-1.62), and 62.0% and 58.3% (OR 1.23, 95% confidence interval 0.89-1.70). Treatment satisfaction at week 26 was significantly greater with tadalafil/finasteride versus placebo/finasteride for total treatment satisfaction scale score (P=0.031) and satisfaction with efficacy subscore (P = 0.025); scores were not significantly different between treatments for satisfaction with dosing or side-effects (both P ≥ 0.371).

Randomized studies of Serenoa repens, alone or in combination with other plant extracts, have provided the strongest evidence for efficacy and tolerability in treatment of BPH in comparison with other phytotherapies. Serenoa repens appears to be a useful option for improving lower urinary tract symptoms and flow measures. Hypoxis rooperi and Secale cereale also appear to improve BPH symptoms although the evidence is less strong for these products. Pygeum africanum has been studied extensively but inadequate reporting of outcomes limits the ability to conclusively recommend it. There is no convincing evidence supporting the use of Urtica dioica or Curcubita pepo alone for treatment of BPH. Overall, phytotherapies are less costly, well tolerated and adverse events are generally mild and infrequent. Future randomized controlled trials using standardized preparations of phytotherapeutic agents with longer study durations are needed to determine their long-term effectiveness in the treatment of BPH.

Androgenetic alopecia occurs in men and women, and is characterised by the loss of hair from the scalp in a defined pattern. Determining factors appear to be genetic predisposition coupled with the presence of sufficient circulating androgens. The prevalence of this condition is high (up to 50% of white males are affected by 50 years of age) and, although there are no serious direct health consequences, the loss of scalp hair can be distressing. Knowledge of the pathogenesis of androgenetic alopecia has increased markedly in recent years. Pre-programmed follicles on the scalp undergo a transformation from long growth (anagen) and short rest (telogen) cycles, to long rest and short growth cycles. This process is coupled with progressive miniaturisation of the follicle. These changes are androgen dependent, and require the inheritance of several genes. To date, only one of these genes, which encodes the androgen receptor (AR), has been identified. Of the many treatments available for androgenetic alopecia, only two (finasteride and minoxidil) have been scientifically shown to be useful in the treatment of hair loss. However, these therapies are variable in their effectiveness. Discovery of the involvement of the AR gene, and the identification of other genes contributing to the condition, might lead to the development of new and more effective therapies that target the condition at a more fundamental level.

Treatment with finasteride resulted in significant improvements from baseline, compared with placebo, in scalp hair based on global photographic assessment (p < .01) and hair counts (p < .01) at week 48. Visible increases in superior/frontal scalp hair post-transplant were recorded for 94% and 67% of patients in the finasteride and placebo groups, respectively. Finasteride treatment was generally well tolerated.

Sixteen of 18 patients have continued finasteride therapy. Mean follow-up is 31 months (range 10 to 47). Twelve had undergone prior prostatectomy. In this group, 3 patients had grade 1, 5 grade 2, and 4 grade 3 hematuria prior to treatment with finasteride. During finasteride therapy, 9 patients had grade 0, 2 grade 1 (pretreatment grades 2 and 3), and 1 grade 3 (pretreatment grade 3) hematuria. Of the 4 patients without prior prostate surgery, 2 had grade 0 (pretreatment grades 1 and 3), and 2 had grade 1 (pretreatment grade 2) hematuria. In summary, 14 of 16 patients improved according to their hematuria grade. We have since added another 10 patients to our study, with a mean follow-up of 11 months. Six of 7 patients who had previous prostatectomies in this group now have grade 0 hematuria. Overall, 8 of the 10 have improved according to hematuria grade.

Results from this study, combined with those from previous studies, indicate an association of prostate cancer with reduced 5alpha-reductase enzymatic activity as a result of remarkably decreased expression of the SRD5A2 gene. The implications of this study for finasteride therapy of prostate cancer are discussed.

The sigma1 receptor is critically involved in the rewarding effect of cocaine, as measured using the conditioned place preference (CPP) procedure in mice. Neuroactive steroids exert rapid neuromodulatory effects in the brain by interacting with GABA(A), NMDA, and sigma1 receptors. At the sigma1 receptor level, 3beta-hydroxy-5-androsten-17-one [dehydroepiandrosterone (DHEA)] and 3beta-hydroxy-5-pregnen-20-one (pregnenolone) act as agonists, whereas 4-pregnene-3,20-dione (progesterone) is an efficient antagonist. The present study sought to investigate the action of neuroactive steroids in acquisition of cocaine-induced CPP in C57BL/6 mice. None of these steroids induced CPP alone. However, pretreatment with DHEA or pregnenolone (5-20 mg/kg, s.c.) during conditioning with cocaine (10 mg/kg, i.p.) increased the conditioned score. On the contrary, pretreatment with either progesterone (10 or 20 mg/kg, s.c.) or finasteride (25 mg/kg, twice a day), a 5alpha-reductase inhibitor, blocked acquisition of cocaine (20 mg/kg)-induced CPP. A crossed pharmacology was observed between steroids and sigma1 ligands. The sigma1 antagonist N-[2-(3,4-dichlorophenyl)ethyl]-N-methyl-2-(dimethylamino)ethylamine blocked cocaine-induced CPP and its potentiation by DHEA or pregnenolone. Progesterone blocked cocaine-induced CPP and its potentiation by the sigma1 agonist igmesine. These results showed that neuroactive steroids play a role in cocaine-induced appetence, through their interaction with the sigma1 receptor. Therefore, neuroendocrine control of cocaine addiction may not involve solely glucocorticoids. The importance of neuroactive steroids as factors of individual vulnerability to drug addiction should, thus, be considered.

Hair loss or hair thinning is a common complaint in clinical dermatology, and patients seeking advice for hair loss are not necessarily bald. Also the effects of treatment attempts are hard to measure. Consequently, there is a need for a sensitive tool to monitor hair loss and treatment response. Such a method must be able to analyze the biological parameters of hair growth, which are: 1: hair density (n/cm2), 2: hair diameter (mm), 3: hair growth rate (mm/day) and 4: anagen/telogen ratio. Here we present the TrichoScan as a method which combines epiluminescence microscopy (ELM) with automatic digital image analysis for the measurement of human, and potentially animal hair, in situ. The TrichoScan is able to analyze all biological parameters of hair growth with a so-called intraclass correlation of approx. ninety-one percent with the same TrichoScan operator and an intraclass correlation of approx. ninety-seven percent for different TrichoScan operators. The application of the technique is demonstrated by comparison of the hair parameters in individuals without apparent hair loss with men with untreated AGA and men after treatment with finasteride (1 mg/day), where we were able to detect a significant increase in hair counts and cumulative hair thickness 3 and 6 months after treatment. The advantage of the TrichoScan is that it can be used for clinical studies to compare placebo versus treatment or to compare different capacities of different hair growth promoting substances, it can be used for studying AGA or other forms of diffuse hair loss, and it can be adopted to study the effect of drugs or laser treatment on hypertrichosis or hirsutism.

Idiopathic hirsutism (IH) is defined as hirsutism in conjunction with normal ovulatory function and normal serum androgen levels. The pathogenesis of IH is still not clear. Increased peripheral 5alpha-reductase enzyme activity and abnormalities of androgen receptor gene polymorphisms have been postulated to explain the pathogenesis of this disorder. It is diagnosed in women who have hirsutism, normal ovulatory function, and normal levels of serum total or free testosterone. Combination treatment of IH, including androgen suppression, peripheral androgen blockade and cosmetic methods is most effective.

Finasteride (MK-0906), a drug used for the treatment of benign prostatic hyperplasia, is a highly specific inhibitor of steroid 5 alpha-reductase, an enzyme that converts testosterone (T) to dihydrotestosterone (DHT) in animals and humans. In a study to evaluate the effect of finasteride on the growth of green alga, Selenastrum capricornutum, the parent drug was not detected by HPLC in the posttreatment (14 day) samples, suggesting complete biotransformation. Thermospray LC/MS, followed by NMR analysis, indicated that the major algal metabolite was 11 alpha-hydroxy-finasteride. This metabolite has negligible in vitro bioactivity buy propecia online against human prostatic 5 alpha-reductase; its potency is only 2% that of finasteride. The primary metabolite of finasteride produced by the green alga involved a biotransformation not previously observed in mammalian and human studies. The green alga effectively deactivates the drug, thereby mitigating any potential environmental impact.

The inhibition of steroid 5alpha-reductase (5AR) by Delta(1)-4-azasteroids is characterized by a two-step time-dependent kinetic mechanism where inhibitor combines with enzyme in a fast equilibrium, defined by the inhibition constant K(i), to form an initial reversible enzyme-inhibitor complex, which subsequently undergoes a time-dependent chemical rearrangement, defined by the rate constant k(3), leading to the formation of an apparently irreversible, tight-binding enzyme-inhibitor complex (Tian, G., Mook, R. A., Jr., Moss buy propecia online , M. L., and Frye, S. V. (1995) Biochemistry 34, 13453-13459). A detailed kinetic analysis of this process with a series of Delta(1)-4-azasteroids having different C-17 substituents was performed to understand the relationships between the rate of time-dependent inhibition and the affinity of the time-dependent inhibitors for the enzyme. A linear correlation was observed between ln(1/K(i)), which is proportional to the ligand binding energy for the formation of the enzyme-inhibitor complex, and ln(1/(k(3)/K(i))), which is proportional to the activation energy for the inhibition reaction under the second order reaction condition, which leads to the formation of the irreversible, tight-binding enzyme-inhibitor complex. The coefficient of the correlation was -0.88 +/- 0.07 for type 1 5AR and -1.0 +/- 0.2 for type 2 5AR. In comparison, there was no obvious correlation between ln(1/K(i)) and ln(1/k(3)), which is proportional to the activation energy of the second, time-dependent step of the inhibition reaction. These data are consistent with a model where ligand binding energies provided at C-17 of Delta(1)-4-azasteroids is fully expressed to lower the activation energy of k(3)/K(i) with little perturbation of the energy barrier of the second, time-dependent step.

At replacement doses, testosterone produces only modest increases in muscle strength and bone mineral density in older hypogonadal men. Although higher doses of testosterone are more anabolic, there is concern over increased adverse effects, notably prostate enlargement. We tested a novel strategy for obtaining robust anabolic effects without prostate enlargement. Orchiectomized (ORX) male rats were treated for 56 days with 1.0 mg testosterone/day, with and without 0.75 mg/day of the 5alpha-reductase inhibitor MK-434. Testosterone administration elevated the prostate dihydrotestosterone concentration and caused prostate enlargement. Both effects were inhibited by MK-434. ORX produced a catabolic state manifested in reduced food intake, blunted weight gain, reduced hemoglobin concentration, decreased kidney mass, and increased bone resorption, and in the proximal tibia there was both decreased cancellous bone volume and a decreased number of trabeculae. In soleus and extensor digitorum longus muscles, ORX reduced both the percentage of type I muscle fibers and the cross-sectional area of type 1 and 2 fibers. Testosterone administration caused a number of anabolic effects, including increases in food intake, hemoglobin concentration, and grip strength, and reversed the catabolic effects of ORX on bone. Testosterone administration also partially reversed ORX-induced changes in muscle fibers. In contrast to the prostate effects of testosterone, the effects on muscle, bone, and hemoglobin concentration were not blocked by MK-434. Our study demonstrates that the effects of testosterone on muscle and bone can be separated from the prostate effects and provides a buy propecia online testable strategy for combating sarcopenia and osteopenia in older hypogonadal men.

Finasteride (Proscar), a 4-azosteroid, is an inhibitor of the enzyme 5-alpha reductase, which is responsible for the conversion of testosterone to the biologically more active dihydrotestosterone (DHT). We report 3 years of experience with the drug in 23 men. Persistent significant decreases in serum DHT and prostate-specific antigen (PSA) were documented. Prostatic volume decreased by about 25% after 1 year, and remained fairly constant thereafter. Urination improved, as evidenced by increased maximal flow rate and decreased volume of residual urine. Symptoms were affected favorably, but only mildly. One of the main advantages of the drug buy propecia online is its lack of side-effects. More data on a larger number of patients with a longer follow-up are needed before finasteride can be established as having a role as an alternative treatment for BPH.

Benign prostatic hyperplasia (BPH), a nonmalignant enlargement of the prostate, can lead to obstructive and irritative lower urinary tract symptoms (LUTS). The pharmacologic use of plants and herbs (phytotherapy) for the treatment of LUTS associated with BPH is common. The extract of the berry of the American saw palmetto, or dwarf palm plant, Serenoa buy propecia online repens (also known by its botanical name of Sabal serrulatum), is one of several phytotherapeutic agents available for the treatment of BPH.

The decrease in levels of PSA in such a group of patients with M1 cancer of the prostate over a 24-week period was surprisingly large, and the differences in these decreased levels between the three treatment arms were remarkably small. There were no apparent differences in bone scan scores, World Health Organization (WHO) performance status, and pain scores between the arms Augmentin Dosage . With regard to sexual function associated with quality of life, there were the understandable difficulties of data collection from patients treated with goserelin.

Finasteride is a specific 5-alpha-reductase inhibitor that has been shown to reduce prostate size and decrease serum levels of prostate specific antigen (PSA). Among men who received finasteride (5 mg/day) for 12 months in North American clinical trials and in whom prostate cancer was not diagnosed the median percentage change in PSA was -50% (5-95% range: -81% to +20%). At baseline 72% had PSA < or = 4.0 ng/ml and 93% had PSA < or = 10.0 ng/ml. After 12 months on finasteride, 75% had PSA < or = 2.0 ng/ml and 95% had PSA < or = 5.0 ng/ml. Thus, the proportion of BPH patients with PSA levels of 2.0 ng/ml and 5.0 ng/ml after 12 months of treatment was comparable to the proportion with pretreatment PSA levels of 4.0 ng/ml and 10.0 ng/ml. Among the 10 men in these trials subsequently diagnosed with prostate cancer while on long-term finasteride therapy (5 mg/day), the median percentage change in PSA was -26% (range: -48% to +12%). Limited experience with finasteride in men with prostate cancer suggests that the reduction in PSA of malignant origin appears to be no greater than the percentage reduction in PSA of benign origin. These effects on PSA have not been shown to Prilosec 60 Mg confer any therapeutic benefit. Physicians using finasteride should be aware of its effect on PSA levels.

Benign prostatic hyperplasia (BPH) is a common urological disorder of men. The ethnomedicinal use of an African plant Prunus africana (Hook.f.) Kalkman (Pygeum) in treating men's Zanaflex Online problems made it a popular remedy all over the globe for the treatment of BPH and related disorders. However, rampant collections made from the wild in Africa have pushed the plant to Appendix II of CITES demanding conservation of the species.

Mean CAG repeat length did not differ between cases Indocin 1 Mg and controls. The frequency distribution of cases and controls for the AR CAG repeat length was similar. There were no significant associations of CAG repeat length with prostate cancer risk when stratified by treatment arm (finasteride or placebo), or when combined. There was also no significant association between CAG repeat length and the risk of low or high grade prostate cancer.

Risk factors for prostate cancer on biopsy for men receiving finasteride include PSA, DRE, age, race, family history, and history of a prior negative biopsy. With the exception of the approximate reduction of PSA by half with finasteride, the impact of these risk factors is similar to men who do Bactrim 300 Mg not receive finasteride.

Allopregnanolone is a neurosteroid involved in depression, memory, social, and sexual behavior. We have previously demonstrated that treatment with a combination of ethinylestradiol (EE) and levonorgestrel (LNG), two compounds frequently used in hormonal Cymbalta Therapeutic Dose contraception, decreased brain allopregnanolone concentrations. These changes may contribute to some of the emotional and sexual disorders observed in hormonal contraceptive users.

The balance between glutamate- and GABA-mediated neurotransmission in the brain is fundamental in the nervous system, but it is regulated by the "tonic" release of a variety of endogenous factors. One such important group of molecules are the neurosteroids (NSs) which, similarly to benzodiazepines (BDZs), enhance GABAergic neurotransmission. The purpose of our work was to investigate, at in vivo physiologically relevant concentrations, the effects of NSs and BDZs as GABA modulators on dissociated neocortical neuron networks grown in long-term culture. We used a multi-electrode array (MEA) recording technique and a novel analysis that was able to both identify the action potentials of engaged excitatory and inhibitory neurons and to detect drug-induced network up-states (burst). We found that the NSs tetrahydrodeoxycorticosterone (THDOC) and allopregnanolone (ALLO) applied at low nanomolar concentrations, produced different modulatory effects on the two neuronal clusters. Conversely, at high concentrations (1 μM), both NSs, decreased excitatory and inhibitory neuron cluster excitability; however, even several hours after wash-out, the excitability of inhibitory neurons continued to be depressed, leading to a network long-term depression (LTD). The BDZs clonazepam (CLZ) and midazolam (MDZ) also decreased the network excitability, but only MDZ caused LTD of inhibitory neuron cluster. To investigate the origin of the LTD after MDZ application, we tested finasteride (FIN), an inhibitor of endogenous NSs synthesis. FIN did not prevent the LTD induced by MDZ, but surprisingly induced it after application of CLZ. The significance and possible mechanisms underlying these LTD effects of NSs and BDZs are discussed. Taken together, our results not only demonstrate that ex vivo networks show a sensitivity to Lamictal Overdose Amount NSs and BDZs comparable to that expressed in vivo, but also provide a new global in vitro description that can help in understanding their activity in more complex systems.

Metyrapone, a cytochrome P(450) inhibitor Aggrenox Capsule used to inhibit corticosterone synthesis, triggers biological markers of stress and also reduces stress-induced anxiety-like behaviors. To address these controversial effects, 6 separate investigations were carried out. In a first set of investigations, abdominal temperature (T(abd)), spontaneous locomotor activity (A(S)) and electroencephalogram (EEG) were recorded in freely moving rats treated with either saline or 150 mg kg(-1) metyrapone. An increase in T(abd) and A(S) occurred in saline rats, while, metyrapone rats exhibited an immediate decrease, both variables returning to basal values 5h later. Concomitantly, the EEG spectral power increased in the gamma and beta 2 bands and decreased in the alpha frequency band, and the EMG spectral power increased. This finding suggests that metyrapone depressed stress-induced physiological response while arousing the animal. In a second step, restraint stress was applied 5h after injection. Metyrapone significantly blunted the stress-induced T(abd) and A(S) rise, without affecting the brain c-fos mRNA increase. Corticosterone (5 and 40 mg kg(-1)) injected concomitantly to metyrapone failed to reverse the observed metyrapone-induced effects in T(abd) and A(S). Finasteride (50 mg kg(-1)), which blocks neurosteroid production, was also unable to block these effects. In conclusion, metyrapone acutely reduced stress-induced physiological response in freely behaving rats independently from glucocorticoids and neurosteroids.

Median PSA level in PBH patients was 1.6 ng/mL for the finasteride-treated group and 3.5 for the untreated group, p < 0.0001. Free PSA ratio was 18.6 and 18.8%, respectively, p > 0.05. Carcinoma detection rate was 25% (4/16) for the finasteride group and 27.2% (34/125) for the untreated group. If biopsy had been requested when PSA percentage was below 25%, 17.7 and 19.8% respectively would have been prevented and all carcinoma detected.

Twice as many exposed men were identified with prostate cancer (239 vs 124 unexposed men, respectively; odds ratio [OR], 2.19; 95% confidence interval [95% CI], 1.75-2.75). This increased risk also was observed in a Cox proportional hazards model from the time of exposure to diagnosis (hazards ratio [HR], 2.87; 95% CI, 2.31-3.57). The mean time from exposure to diagnosis was 407 months. Agent Orange-exposed men were diagnosed at a younger age (59.7 years; 95% CI, 58.9-60.5 years) compared with unexposed men (62.2 years; 95% CI, 60.8-63.6 years), had a 2-fold increase in the proportion of Gleason scores 8 through 10 (21.8%; 95% CI, 16.5%-27%) compared with unexposed men (10.5%; 95% CI, 5%-15.9%), and were more likely to have metastatic disease at presentation than men who were not exposed (13.4%; 95% CI, 9%-17.7%) than unexposed men (4%; 95% CI, 0.5%-7.5%). In univariate analysis, distribution by race, smoking history, body mass index, finasteride exposure, clinical stage, and mean prebiopsy PSA were not statistically different. In a multivariate logistic regression model, Agent Orange was the most important predictor not only of developing prostate cancer but also of high-grade and metastatic disease on presentation.
