Waa maxay daawaynta?
Theranostics waa ereyga isku darka daawaynta iyo ogaanshaha (iyada oo la isticmaalayo hal radionuclide si loo sawiro burooyinka iyo radionuclide labaad si loo daweeyo burooyinka iyadoo la siinayo shucaaca dilaaga kansarka). Asal ahaan, waxay ka dhigan tahay in la beegsado hal unug soo-celin ah unugyada kansarka leh laba radionuclides oo kala duwan (sawir iyo daaweyn). Tani waa si loo gaaro istiraatiijiyad daawaynta saxda ah oo shaqsiyeysan.
Marxaladda ogaanshaha ee Theranostics
Unugyada buradu waxay leeyihiin qolof, loo yaqaan xuub; Waxaa jira borotiinno gaar ah sida somatostatin receptor (SSTR2) oo ku yaal xuubka unugyada burooyinka kaas oo u adeegi kara bartilmaameedka daawooyinka kansarka.
Ga-68 DOTATOC waa daawada ogaanshaha shucaaca ee bartilmaameedka SSTR2. Ga-68 DOTATOC waxaa lagu duraa xididka bukaanka waxayna ku socotaa dhiiga ilaa dhammaan xubnaha iyo unugyada jirka. Haddii bukaanku uu leeyahay burada neuroendocrine oo leh SSTR2 oo ku taal xuubabka unugyada burooyinka, Ga-68 DOTATOC waxay ku xidhmi doontaa SSTR2 buraduna waxay iftiimin doontaa baaritaanka PET
Marxaladda daawaynta ee Theranostics
Marka kansarka neuroendocrine la ogaado iyadoo la isticmaalayo Ga68-DOTATOC PET scan, Ga-68 waxaa lagu bedeli karaa radionuclide kale, sida lutium-177 (Lu-177) ama yttrium-90 (Y-90), kaas oo beegsan kara oo dili kara unugyada burooyinka. kuwaas oo leh SSTR2 xuubkooda.
Therapeutic Y-90-DOTATOC iyo Lu-177-DOTATATE labaduba waa la isku duri karaa xididdada bukaanka waxayna u safri karaan qayb kasta oo jidhka ka mid ah oo leh borotiinnada SSTR2. Daawooyinkan daweynta ah waxay ku xidhan yihiin borotiinka SSTR2 sida furaha qufulka, taas oo u oggolaanaysa daawadu inay gasho unugyada burooyinka oo ay disho iyada oo dhaawacaysa DNA-da unuggaas. Unugyada caafimaadka qaba ee ku wareegsan burada oo aan lahayn borotiinada SSTR2 ee xuubkooda ma saameynayso dawadu.
Istaraatiijiyada noocan oo kale ah waxay u ogolaataa dhakhaatiirta kansarka in ay si buuxda u sawiraan unugyada kansarka ee la daweyn karo, ay doortaan bukaanada codsiyada daweynta, si sax ah u eegaan halka wakiilada daweynta la geyn doono, oo ay la socdaan awoodda wakiilka daweynta si uu u yareeyo burooyinka waqti ka dib. Theranostics waxay siisaa dhakhaatiirta oncologists qalab cusub oo aad waxtar u leh si ay u abuuraan xeelado daawaynta saxda ah oo ay saadaaliyaan faa'iidooyinka daaweyn gaar ah oo ku salaysan bukaannada astaanta unugyada iyo hiddaha.
DAAWAYNTA: ARKIN WAXAAN DAAWAYNAYNAA- DAAWAYNAYNAA WAXA AAN ARAGNO
Tani sidoo kale waa la yaqaan daaweynta radionuclide ee la beegsaday iyada oo ujeedadu tahay bartilmaameedka molecular ee gaarka ah ee unugyada kansarka ee shaqeeya. Sidaa darteed, qiyaas sare oo shucaac ah ayaa lagu beegsan karaa burada iyada oo aan saameynin unugyo badan oo caafimaad qaba.
Sidee daawayntu uga duwan tahay shucaaca caadiga ah?
Dawaynta shucaaca ayaa aad waxtar u leh daawaynta kansarka, ama yaraynta calaamadaha bukaanka qaba kansar heer sare ah oo aan la dawayn karin. Qiyaastii kala badh dhammaan bukaannada kansarka ayaa heli doona daawaynta shucaaca mar uun daawayntooda, taas oo adeegsata raajo dibadda ama gudaha la bixiyo, protons ama qaybo kale oo tamar sare leh si loo beegsado loona burburiyo unugyada kansarka. Iyadoo la wanaajiyey hababka teknoolajiyada ay hoos u dhigeen xumaanshaha unugyada caafimaadka qaba, shucaaca dhaqameed ayaa wali keena waxyeelooyin ay ku adkaan karto bukaanada qaarkood inay u dulqaataan. Intaa waxaa dheer, shucaac dhaqameed ma awoodo in la beegsado wax ka badan hal goob oo cudur ah, taas oo xaddidaysa isticmaalka bukaannada qaba kansarka dheef-shiid kiimikaadka. Si kastaba ha ahaatee, shucaaca dhaqameed ayaa weli ah mid ka mid ah qalabka daaweynta ugu awoodda badan oncology.
Habkan cusub ee daaweynta burooyinka - daawaynta radionuclide ee la beegsaday - ayaa dib u habayn ku samaynaysa isticmaalka daawaynta shucaaca ee saxda ah ee kansarka iyo bixinta fasal cusub oo daawaynta kansarka ah. Hadafka horumarinta daawaynta radionuclide ee la beegsanayo waa in la isku daro alfa-, beta- ama gamma-particle soo saara isotopes - ama radionuclides - oo leh peptides, unugyada difaaca jirka, ama molecules yaryar, si loo horumariyo daweyn gaar ah oo gaar ah noocyada burooyinka qaarkood. Waxaa loo geeyaa bukaanka xididada, daawaynta radionuclide ee la beegsaday waxaa loogu talagalay inay si toos ah ugu safraan burada si ay u bixiyaan shucaac daweyn oo sax ah. Saxnimadan waxaa loogu talagalay in diiradda la saaro gaarsiinta shucaaca unugyada burada iyadoo la yareynayo soo-gaadhista shucaaca ee unugyada caadiga ah.
Noocee ah kansar ayaa lagu daweyn karaa teranostics?
Theranostics waxay noqon kartaa wax ku ool ah daawaynta metastatic, burooyinka aan shaqaynayn marxaladda hore ee cudurrada oo ay ku jiraan kansarka qanjirka 'prostate', burooyinka neuroendocrine ee xubnaha kala duwan sida caloosha, beeryarada, yar & xiidmaha waaweyn iyo sambabada. Ugu dambeyntii, laakiin aan ugu yareyn, ka-saarista qalliinka ka dib ee hadhaaga tayroodhka iyo daawaynta kansarka tayroodhka metastatic ayaa sidoo kale ku jira gamut of theranostics.
Kansarrada kor ku xusan waxay haystaan caddayn ku filan oo hadda la hayo in ay jirto faa'iido qeexan oo ku jirta isticmaalka daawaynta radionuclide. Si kastaba ha ahaatee, kansarro kale oo badan ayaa sidoo kale laga yaabaa inay faa'iido u yeeshaan marka ay muujiyaan noocyada qaar ee soo-dhoweynta bartilmaameedka ah sida borotiinka firfircoonida fibroblast (FAP) iyo chemokine reseptors (CXCR4), ayaa lagu bartilmaameedsan karaa daaweeyayaasha.
