Tiyeni tiphunzire za Radiopharmaceuticals m'njira yosavuta. Izi zidzakhala zofunika kwambiri kwa inu!

Mwina mumaopa pang'ono mukamva mawu oti "radiopharmaceuticals," sichoncho? Mawu oti "radioactive" nthawi yomweyo amakukumbutsani chinthu choopsa, koma akagwiritsidwa ntchito bwino mu zamankhwala, akhoza kukhala othandiza kwambiri. Kotero lero, tiyeni tikambirane za zomwe zili, momwe zimagwirira ntchito, komanso momwe zilili zotetezeka kwa inu.

Kodi mankhwala opangidwa ndi radiopharmaceuticals awa ndi ati? Tiyeni timvetse mosavuta!

Mwachidule, awa `(Radiopharmaceuticals)` ndi mtundu wapadera wa mankhwala . Koma ali ndi chinthu chowopsa pang'ono, ndiko kuti, ndi chowopsa. Musadandaule, ichi ndi radioactivity yolamulidwa komanso yotetezeka. Madokotala athu, ndiko kuti, madokotala ndi othandizira azaumoyo ena, amagwiritsa ntchito mankhwalawa pojambula zithunzi mu mankhwala a nyukiliya komanso pochiza matenda ena, makamaka khansa .

Taganizirani izi, akafuna kuona ngati pali vuto m'thupi lanu, nthawi zina madokotala amakupatsirani mankhwala pang'ono kuti mumwe kapena jakisoni musanajambule? Izi ndi zina zotero. Mankhwala apaderawa amapangidwa ndi kuperekedwa ndi anthu ophunzitsidwa bwino otchedwa ma pharmacist a nyukiliya . Kenako , akatswiri a radiology ndi akatswiri a radiology (RTs) amawagwiritsa ntchito poyesa kujambula matenda. Nthawi zina, akatswiri a radiation oncologists amaperekanso mankhwala awa ngati chithandizo.

Kodi mankhwala opangidwa ndi radiopharmaceutical awa amagwiritsidwa ntchito pa chiyani?

Mankhwalawa amagwiritsidwa ntchito makamaka m'magawo awiri. Tiyeni tiwone zomwe zili.

1. Mankhwala Ozindikira Matenda a Radiopharmaceuticals

Mankhwala ochizira matenda a nyukiliya nthawi zambiri amagwiritsidwa ntchito poyesa kujambula mankhwala a nyukiliya . Timatcha izi "mankhwala ochizira matenda a nyukiliya." Ku United States kokha, akuti mayeso mamiliyoni ambiri a mankhwala a nyukiliya amachitidwa chaka chilichonse. Kotero mutha kulingalira momwe amagwiritsidwira ntchito kwambiri.

Mayeso awa amatha kuwona ngati ziwalo ndi minofu mkati mwa thupi lanu ikugwira ntchito bwino . Izi zimachitika motere:

Mumapatsidwa mankhwala ochepa kwambiri a radioactive kuti mumwe, mupume mpweya, kapena mujambule. Nthawi zina mankhwalawa amatchedwa radiotracers . Kuchuluka kwa mankhwala a radioactive omwe mumapatsidwa sikungakupwetekeni. Ndi ochepa kwambiri. Mankhwalawa amapita kumalo komwe kuli vuto m'thupi lanu ndipo amasonkhanitsa. Kenako, kamera yodziwika bwino, monga kamera ya gamma, imazindikira kuwala m'thupi lanu ndikupanga zithunzi zomwe dokotala angaone.

Tangoganizani, mankhwala awa ali ngati wofufuza amene akupita m'thupi, kupeza malo omwe ali ndi vuto ndikutiwonetsa kuti, "Apa ndi pomwe pali vuto."

Nazi zitsanzo za momwe ma radiopharmaceuticals amagwiritsidwira ntchito pozindikira matenda:

• Fluorine-18: Ichi ndi choyezera ma radiotracer chomwe chimagwiritsidwa ntchito nthawi zambiri mu PET scans (Positron Emission Tomography scans).
• Technetium 99m: Ichi ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pochiza matenda a nyukiliya. Chimagwiritsidwa ntchito pofufuza mafupa, chiwindi, ndi impso.
• Xenon-133: Iyi ndi mankhwala owopsa omwe mumapuma. Amaperekedwa kuti aone momwe mapapo amagwirira ntchito (kuyeza ntchito ya mapapo).
• Rubidium-82: Iyi ndi mankhwala omwe amaperekedwa kwa inu kudzera m'mitsempha (IV). Amagwiritsidwa ntchito poyang'ana momwe minofu ya mtima ilili (myocardial imaging).

2. Mankhwala Ochiritsira a Radiopharmaceuticals

Tsopano tiyeni tikambirane za momwe mankhwalawa amagwiritsidwira ntchito pochiza. Izi ndizosiyana pang'ono ndi zomwe zimagwiritsidwa ntchito pochiza matenda. Ma radiopharmaceuticals omwe amagwiritsidwa ntchito pochiza amatulutsa mphamvu kwambiri komanso ma cell-male radiation . Izi zimachitika kuti aphe maselo osadwala, makamaka maselo a khansa .

Mankhwalawa ali ngati "osaka chuma." Izi zikutanthauza kuti, amapeza maselo a khansa ndikupereka chithandizo cha radiation mwachindunji ku maselo amenewo . Izi ndi zosiyana ndi chithandizo cha radiation chakunja , chomwe chimagwiritsa ntchito makina kutumiza kuwala kwa radiation kuchokera kunja kwa thupi lanu. Koma mankhwala ochiritsira awa amagwira ntchito mwachindunji polunjika cholinga.

Gawo ili, kugwiritsa ntchito mankhwala owononga mphamvu ya radioactive pochiza, ndi latsopano. Ofufuza akufufuzabe momwe angagwiritsire ntchito mankhwala atsopano. Akukhulupirira kuti mankhwala ochiritsa a radiopharmaceuticals adzakhala ndi gawo lofunika kwambiri pochiza khansa mtsogolo.

Kodi mankhwala a radiopharmaceuticals amagwiritsidwa ntchito pochiza khansa?

Pali mitundu ingapo ya ``Radiopharmaceuticals`` yomwe madokotala amagwiritsa ntchito pochiza khansa. Mwachitsanzo:

• PLUVICTO® (lutetium Lu 177 vipivotide tetraxetan): Iyi ndi mankhwala ovomerezeka ndi US Food and Drug Administration (FDA). Amagwiritsidwa ntchito pochiza khansa ya prostate (PSMA-positive metastatic castration-resistant prostate cancer - PSMA-positive mCRPC).
• Lutathera™ `(Lutathera™ - Lutetium Lu 177 dotatate)`:Mankhwalawa ndi ovomerezeka ndi FDA. Amagwiritsidwa ntchito pochiza zotupa zina za neuroendocrine (somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors) zomwe zimapezeka m'mimba, m'matumbo, ndi kapamba.
• Iodine-131: Iyi ndiyo njira yaikulu yochiritsira ayodini pogwiritsa ntchito radioactive. Imatha kuchiza khansa zina za chithokomiro ndi matenda ena a Graves, omwe amadziwikanso kuti hyperthyroidism.
• Radium-223: Izi zimathandiza kwambiri pochiza zotupa za m'mafupa zomwe zimachitika khansa ya prostate ikafalikira (kufalikira kwa mafupa) kupita ku mafupa. Bungwe la US FDA lavomereza Radium-223 dichloride (Xofigo™) pachifukwa ichi.

Kuphatikiza apo, mitundu ina ingapo ya mankhwala ochizira khansa ya radiopharmaceutical ikuyesedwa kuchipatala pa mitundu ina ya khansa.

Kodi mankhwala ochizira matenda a radiopharmaceutical omwe amagwiritsidwa ntchito kwambiri ndi ati?

Monga tanenera kale, Technetium-99m ndi mankhwala ochizira matenda omwe madokotala amagwiritsa ntchito nthawi zambiri. Amagwiritsidwa ntchito makamaka poyesa matenda. Zimathandiza "kuona" zotsatirazi:

• Kutuluka kwa magazi m'mapapo mwanu.
• Kuyenda kwa magazi m'mitsempha yanu yamagazi (kutuluka kwa magazi m'mitsempha).
• Mafupa.
• Minofu ya myocardial.
• Ma gland a lacrimal.
• Chithokomiro cha chithokomiro.

Mankhwala ena odziwika bwino a radiopharmaceuticals ndi awa:

• ¹⁸F Fluorodeoxyglucose `(¹⁸F Fluorodeoxyglucose - FDG)`
• Gallium-68 DOTATATE
• Gallium-68 PSMA `(Gallium-68 PSMA)`
• ¹⁸F PSMA `(¹⁸F PSMA)`
• Ayodini 123 `(ayodini 123)`

Kodi mankhwala opangidwa ndi radiopharmaceuticals awa ndi otetezekadi?

Funso ili ndi lomwe anthu ambiri amafunsa. Ngati agwiritsidwa ntchito bwino, mankhwala ochizira matenda a radiopharmaceutical ndi otetezeka. Katswiri wanu wa radiation ndi/kapena katswiri wa khansa ya radiation adzagwira ntchito ndi katswiri wa mankhwala a nyukiliya kuti atsimikizire kuti kuchuluka kwa mankhwala ochizira matenda a radiopharmaceutical omwe mwapatsidwa ndi kolondola komanso kotetezeka . Choncho palibe chodetsa nkhawa.

Monga mankhwala ena onse, chithandizo cha radiation chingayambitse zotsatirapo zina . Komabe, ubwino wa mankhwalawa nthawi zambiri umakhala waukulu kuposa zoopsa zake. Dokotala wanu adzakufotokozerani zotsatirapo izi musanayambe kulandira chithandizo.

Ngakhale kuti mankhwala opangidwa ndi radiopharmaceuticals akhala akugwiritsidwa ntchito kwa zaka zambiri pojambula mankhwala a nyukiliya, angoyamba kumene kugwiritsidwa ntchito pochiza khansa. Ofufuza akuphunzirabe momwe mankhwala opangidwa ndi radiopharmaceuticals awa amalimbana ndi kupha maselo a khansa. Ngati mukufuna kudziwa za mayeso azachipatala a mankhwala opangidwa ndi radiopharmaceuticals pochiza khansa, lankhulani ndi dokotala wanu. Ali okondwa kukuthandizani.

Pomaliza, zinthu zofunika kwambiri zomwe muyenera kukumbukira

Chabwino, kuchokera pa zomwe takambirana, izi ndi zinthu zazikulu zomwe muyenera kukumbukira:

• Mankhwala ochizira matenda a radiopharmaceutical ndi mtundu wapadera wa mankhwala omwe ali ndi mphamvu yolamulira mphamvu ya radioactive .
• Izi zimagwiritsidwa ntchito makamaka poyesa kujambula zithunzi (monga PET scans, bone scans) komanso pochiza matenda ena, makamaka khansa .
• Pozindikira matenda, izi zimagwira ntchito ngati "Radiotracers", "kuwonetsa" madera a thupi omwe ali ndi mavuto.
• Mu mankhwala, izi zimathandiza kuwononga maselo a khansa .
• Mankhwalawa ndi otetezeka akaperekedwa moyang'aniridwa ndi dokotala . Monga mankhwala ena onse, pakhoza kukhala zotsatirapo zazing'ono, koma ubwino wake nthawi zambiri umaposa.
• Gawoli, makamaka pochiza khansa, likusinthabe , ndipo zinthu zambiri zingayembekezeredwe mtsogolo.

Kotero, nthawi ina mukamva za ``(Radiopharmaceutical)'', tsopano mukumvetsa bwino tanthauzo lake ndi zomwe amagwiritsidwa ntchito, sichoncho? Ngati muli ndi mafunso ena, nthawi zonse musazengereze kufunsa dokotala wanu.
