"Viagra and Cancer"
バイアグラの発癌性
Of the half dozen Viagra-type drugs on the market now,
たくさんの種類のバイアグラが発売されています、
Viagra itself may still have the greatest efficacy
バイアグラの効果は絶大ですが、
but also has the highest rate of overall side effects.
副作用も大きいです。
It's still a pretty safe drug.
比較的安全な範囲ですが、
Some guy swallowed 65 at a time
ある人は1度に65錠飲みました。
in hopes he’d go out with a bang,
強気でしたが、
but it didn’t work.
望んだ効果はありませんでした。
The most commonly observed acute side effects
よくある副作用は、
include headache, flushing, stomach upset,
頭痛、閃光、胃炎、
runny nose, and vision abnormalities,
鼻水、視覚障害、
but now that it’s been around for a decade,
発売から10年経過したので、
some chronic effects may be cropping up.
慢性滴な副作用の報告があるでしょう。
For example, glaucoma,
緑内障は、
one of the leading causes of blindness,
失明の原因となり、
caused by degeneration of the optic nerve.
視神経が変性します。
Up to nearly 10 times the odds of glaucoma
バイアグラを長期間使用すると、
among those using Viagra long-term.
緑内障のリスクが10倍になります。
But, it’s cancer that has the medical community
発癌性に関して、
rethinking the safety of these kinds of drugs.
心配されています。
Men with advanced prostate cancer
前立腺癌が進行すると、
often have to get a radical prostatectomy,
治療として前立腺を摘出します、
a surgery that can leave them both incontinent and impotent,
術後は勃起しないので、
which can reduce their quality of life.
不満に思う人もいます。
Therefore, a treatment concept called
ペニスのリハビリを、
“penile rehabilitation” was introduced,
行う人もいます。
where drugs like Viagra are given to counteract
手術の副作用のために、
the side effects of the surgery.
バイアグラが必要となるのです。
But, there have been studies like this,
このような研究もあります、
that found Viagra could decrease natural killer cell activity,
バイアグラはnatural killer cellを減少させて、
and natural killer cells are our first line
癌と戦う最前線の、
of immune defense against cancer.
免疫細胞を減らすのです。
Now, this was a study on women for something else,
女性に対しての研究も行われています、
but it did raise concerns about
しかし、それは
giving Viagra to those battling prostate cancer.
前立腺癌の患者にバイアグラが使用されるのですが。
In terms of getting prostate cancer in the first place,
前立腺癌の初期には、
men treated with Viagra-type drugs
バイアグラの様な薬で治療されると、
tended to have less of a chance
前立腺癌の診断が、
of being diagnosed with prostate cancer;
遅れます、
yeah, but that may just be because
射精が多くなるので、
they’re ejaculating more.
元気だから診断されにくい。
Higher ejaculation frequency may be associated
頻回に射精すると、
with a lower risk of prostate cancer.
前立腺癌のリスクが下がるようです。
It's interesting the reason they think why.
理由は面白いです。
Frequent ejaculations may decrease the concentration
頻回に射精すると、
within the prostate gland itself of xenobiotic compounds,
前立腺で、
like hormone disrupting chemicals and carcinogens.
発癌物質の濃度が低下します。
Anything we eat can end up in our prostate.
飲食物はすべて前立腺に影響します、
Drink a cup of coffee, and you end up with
コーヒーを飲むと、
caffeinated semen 10 hours later.
精液にカフェインが検出されます。
Smoke a cigarette, and the nicotine ends up in the same place.
タバコを吸うと、精液にニコチンが検出されます。
Or eat fish, and end up with
魚を食べると、
one-seventh the healthy sperm count,
健康な精子が 1/7に減少します、
perhaps because there’s like three times
精液中の、PCB濃度が、
the concentration of PCBs.
3倍になっていました。
But, anyway, you don’t know for sure about Viagra,
でも詳細に研究してみるまで、
until you put it to the test.
正確なことはわかりません、
Nearly 5,000 prostate cancer survivors were followed,
5000人の前立腺癌患者を追跡しました、
and those taking Viagra-type drugs
バイアグラを内服していると、
did seem to have a little bump
前立腺癌再発のリスクが、
in their risk of the cancer coming back,
減るようでした、
but subsequent studies failed to find such an association.
その後の研究では関連性が証明されませんでした。
What moved me to make this video is the unexpected connection
とても驚いたことは、
between Viagra and melanoma skin cancer.
バイアグラとメラノーマの関係です。
If treated early, melanoma can be cured by cutting it out,
早期に発見されたメラノーマは切除で完治します。
but due to its proclivity to metastasize,
転移する傾向があるため、
in about 20% of patients, it progresses to an
患者の20%は、
aggressive invasive disease
急激に進行し、
that can kill in a matter of months.
数ヶ月以内に死亡します。
And, part of the way it does this
めらのー
is through a gene mutation in the cancer,
癌ですが、さらに遺伝子変異が生じ、
that induces melanoma cell invasion
phosphodiesterase5を抑制することによって、
by downregulating an enzyme called phosphodiesterase 5.
メラノーマがより悪性になります。
Does that word look familiar?
この現象はよくあるのでしょうか、
That’s what Viagra does.
バイアグラでも生じます。
Viagra works because it’s a phosphodiesterase 5 inhibitor.
バイアグラはphosphodiesterase5を阻害します。
So, Viagra may have the same effect
バイアグラは危険です、
in terms of promoting melanoma growth.
メラノーマを促進するかもしれません。
You don’t know, though...
このような研究が、
until you put it to the test.
行われました。
And, Viagra use was associated with an 84% increased risk
バイアグラの使用は、
of subsequent melanoma diagnosis,
メラノーマを84%増加させました、
and you put all the studies together,
他の研究でも、
and the association remains significant.
バイアグラはメラノーマを増加させました。
So, here we have this class of drugs
バイアグラは、
found in medicine cabinets across the country,
薬局で購入できます、
and the FDA does its best trying to ensure
FDAは安全性を確かめていますが、
the safety and efficacy of such drugs,
分子レベルでは、
but you can’t always anticipate the molecular consequences
予測させる結果以外が、
of inhibiting major cellular pathways.
生じる可能性もあります。
There is, however, an alternative explanation.
他の説明があります。
Maybe users of Viagra are just naked more,
バイアグラを内服する人はsexの機会が多いので、
thus giving their partners the opportunity
パートナーがメラノーマに気づきます、
to notice some suspicious mole or something,
裸になっているので、
as only about 1 in 3 melanomas are discovered
患者自身が見つけたメラノーマは、
by the patients themselves.
全体の1/3です。
