Experimental Pill adds Months to Lives of Prostate Cancer Patients


The drug, called enzalutamide, is a pill that tackles prostate tumors from several different directions, interfering with molecular pathways that help them grow.Men taking enzalutamide lived 37 percent longer on average. The drug, made by a biotechnology company called Medivation is likely to be approved by the Food and Drug Administration within a few months and will cost about $6,000 a month.With medivation there is hope that it could be even more effective if it’s just used in a smarter way.Many cases are treated with radiation or surgery before the cancer starts to spread.Doctors are trying it in men soon after the cancer spreads out of the prostate to the lymph nodes and toward the bones where it becomes life-threatening.The hope is such treatment could bring a far more profound extension of survival. That will not reduce costs, but it would be even more exciting.For now medivation, despite the caveats, represents a huge advance against the second biggest cancer killer of men.Prostate cancer kills kills more than 28,000 U.S. men a year. Many cases are treated with radiation or surgery before the cancer starts to spread.

 Epididymis is a long (about 6 meters) tube that is tightly coiled to form a comma-shaped organ located along the superior and posterior margins of the testes.The primary functions of the testes are to produce sperm (spermatogenesis) and to produce androgens, primarily testosterone. Sperm function is to carry the males genes to the female’s egg for fertilization.The Vas deferens transport sperm from the epididymis in anticipation of ejaculation. Rete testis carries sperm from the seminiferous tubules to the vasa efferentia.It is in the rete testis that the sperm become concentrated and other fluids are reabsorbed.The seminal vesicles secrete a significant proportion of the fluid that ultimately becomes semen.The function of the prostate is to secrete a slightly acidic fluid, milky or white in appearance.During sexual arousal Bulbourethral glands produces a clear, salty, viscous secretion known as pre-ejaculate. The urethra is the tube that carries urine from the bladder to outside of the body and ejaculating semen when the man reaches orgasm.

Prostate cancer would effect the normal function of the male reproductive system by causing problems of urination caused when the gland, enlarged by cancer,which is in the uretha.Begins to block the urethra, the tube that carries urine through the penis. The blockage causes the bladder to retain urine, thus the frequent urge to urinate.The back-up urine in the bladder may become infected, causing burning, painful cloudy and sometimes bloody urination.
