Mtengo Woti "FDA Wavomerezedwa"
Mankhwala atsopano a khansa ya prostate amabwera kumsika kawirikawiri chifukwa maphunziro omwe adalamulidwa ndi FDA amawononga madola mamiliyoni mazana ambiri. A FDA amafuna kuti maphunzirowa apereke amuna mwa magawo awiri kuti agwirizane. Gulu limodzi limalandira mankhwala atsopano poyesedwa. Gulu linanso limapeza fake lopanda ntchito, lotchedwa placebo. Poganiza kuti maphunzirowa akuchitidwa movomerezeka, a FDA amavomereza mankhwala atsopano kuti agwiritse ntchito malonda, pokhapokha ngati amuna omwe akulandira mankhwala atsopano amachotsa mankhwala omwe ali ndi placebo ndi malire omwe alibe poizoni wambiri.
Kupeza mazana a odzipereka omwe akufunitsitsa kuchita nawo maphunzirowa ndi zovuta. Amunawa amadziwa kuti ali ndi mwayi woti adzalandire malo ogwira ntchito. Ndani akufuna kutenga mwayi wopeza mapiritsi a shuga pamene akudwala matenda oopsa? Ngakhale zili choncho, atagwiritsa ntchito njira zonse zomwe angapewere mankhwala, amakhala osimidwa ndikulembera phunzirolo, akuyembekeza kuti ali ndi mwayi ndi kulandira McCoy weniweni.
Maphunzirowa amatha zaka zambiri chifukwa amatha kukwanitsa pamene ambiri mwa ophunzirawo afa ndi khansara yopitirira. Kuti athe kupeza ophunzira, makampani oyang'anira omwe akukonzekera ndikuyambitsa maphunzirowa amafunikira maubwenzi ogwirizana ndi malo zana kapena kuposerapo. Maphunziro apamwamba a maphunzirowa ndi osavuta kumvetsetsa pamene mukuwona zofunikira kuti muzitsatira odwala onsewa, m'malo osiyanasiyana, pa nthawi yaitali.
Kupereka ndi mankhwala amodzi a FDA ochizira khansa ya prostate yomwe yatha kuthetsa mavuto onsewa. Kupereka kumakhala ndi njira yapadera yomwe imagwira ntchito polimbikitsa chitetezo cha mthupi. Dendreon, amene amapanga mavitaminiwa, amachititsa kuti maselo a chitetezo cha m'magazi alowe m'magazi ndi plasmapheresis, maola atatu ofanana ndi dialysis.
Maselo okololedwa amatengedwera ku labotale yapadera ndi kusakaniza ndi zinthu kuti apititse kukwiya kwawo ndi khansa. Maselo omwewo amabwezereranso mmbuyo mwa wodwala yemweyo.
Perekani chofunika kwambiri ndi zotsatira zochepa za zotsatira zake. Komabe, chithandizochi, chomwe sichidalira chemotherapy, ndi chosinthika kuti pambuyo pa kuphunzira koyamba a FDA adaumiriza kampaniyo kubwereza phunziro lawo kuti atsimikizire kuti chithandizochi chikuwonjezeradi moyo chifukwa cha kukayikira. Apanso, kufufuza kwachiwiri kunawonetsa kuti anthu opatsidwa mankhwalawa anali 30% ochuluka kuti akhale ndi moyo zaka zitatu pambuyo pochiza chithandizo poyerekeza ndi amuna omwe analandira placebo. Potsiriza, a FDA adavomereza zotsatirazo ndipo adavomerezedwa. Monga momwe tingaganizire, kuchedwa, osati kutchula mtengo wowonjezereka wobwereza phunzirolo, kunachulukitsa ndalama zowonjezera za kupereka.
Yevtana, njira yowonjezera ya chemotherapy, ndi wothandizira wina yemwe FDA inavomereza pogwiritsa ntchito phunziro lopulumuka mwadzidzidzi. Komabe, mmalo mwa malo a placebo, Jevtana ankafanizidwa ndi mankhwala achikulire omwe amatchedwa Mitoxantrone omwe amachepetsa kupweteka koma samapitiriza kupulumuka. Amuna 755 anapatsidwa mankhwala ndi Jevtana kapena Mitoxantrone.
Kupulumuka kwa amuna omwe adalandira Yevana kunali 30% kuposa amuna omwe anachitidwa ndi Mitoxantrone.
Nkhani ya momwe Sanofi-Aventis anabweretsera Yevtana, mtundu watsopano wa mankhwala a chemotherapy, kuti agulitse ndi zochititsa chidwi chimodzimodzi pokhala kuti kampani ya mankhwala, idaika pangozi yaikulu chifukwa iwo anayesa Yevana mwa amuna omwe kale anali otsutsana ndi Taxotere. (Taxotere imaonedwa kuti ndi "standard" chemotherapy ya khansara ya prostate.) Njira imeneyi inadabwitsa akatswiri a zamalonda chifukwa mbiri yakale, amuna osagwirizana ndi Taxotere ayenera kuyembekezera kwambiri kuti asamapitirize mankhwala enaake. Ngakhale kuti a naysayers, a Jevtana adatsimikiziridwa kuti apulumutse moyo wawo, ngakhale m'gulu la odwala omwe sagonjetsedwa.
Ndalama zamagetsi zamakono zamakono zimakhala zosavuta kumvetsetsa pakuganizira zaka zomwe amaphunzira zomwe zimafuna ndalama zokwana madola mazana ambiri. Jevtana ndi zopereka ndizopambana. Mwamwayi, tikamaganizira za mtengo wapatali wa mankhwalawa tiyeneranso kuthandizira pazoonjezera mtengo wa mankhwala ambiri omwe ayesedwa mu mayesero osayenerera koma alephera kusonyeza kusintha kwa kupulumuka.
Tsopano kuti Yevtana ndi Provenge akhala atatsimikiziridwa kuthandiza amuna kukhala moyo wautali, maphunziro ena akupitirirabe kuti adziwe momwe zida zofunika kwambiri zamagetsi zikhoza kugwiritsidwa ntchito mwa njira yabwino kwambiri. Makamaka, mphamvu zawo zikhoza kupitsidwanso patsogolo poziphatikiza ndi mankhwala ena kapena mitundu yosiyanasiyana ya ma radiation.
