Siyazi ukuba kunzima kangakanani ukulwa nomhlaza webele. Kodwa ngokuqhubeka kwesayensi yezonyango, amathemba amatsha ahlala esongezwa. Namhlanje sithetha ngeyeza elizise ithemba elitsha, iyeza elijolise ngqo kwaye linyange iiseli zomhlaza. Igama leli yeza yiTruqap.
Yintoni iTruqap? Ingaba yahlukile kunyango oluqhelekileyo?
I-Truqap (i-capivasertib) lunyango olujoliswe kumhlaza webele. Ngoku usenokuba uzibuza, "Luluphi olu nyango lujoliswe kulo?"
Ngamafutshane, khawucinge ngegadi enokhula oluninzi. I-chemotherapy eqhelekileyo ifana nokutshiza igadi yonke nge-herbicide. Ingabulala ukhula kunye nezityalo eziphilileyo. Oku kuthetha ukuba nangona i-chemotherapy ibulala iiseli zomhlaza, inokwenzakalisa neeseli eziphilileyo emzimbeni wethu.
Kodwa unyango olujoliswe kulo lufana nokufumana ukhula uze ulutshize kuphela. Luchonga iiproteni ezithile ezinceda iiseli zomhlaza zikhule ngokukhawuleza, kwaye luzithintele ekwenzeni oko. Oku kuthetha ukuba umonakalo kwiiseli ezisempilweni mncinane kakhulu.
I-Truqap yenye yonyango olujoliswe kuyo. I-US FDA yamkela eli yeza ngo-2023, ngokukodwa lomhlaza webele ophucukileyo one-hormone-positive (HR-positive) kwaye unotshintsho oluthile kwimfuza. Eli yeza lidla ngokunikezelwa kunye nolunye unyango lwe-hormone olubizwa ngokuba yi-fulvestrant.
Isebenza njani iTruqap emzimbeni?
Ezinye izigulane ezinomhlaza webele oxhomekeke kwiihomoni (HR-positive) zineziguquguquko kwiijini ezibizwa ngokuba yiPIK3CA, AKT1, okanye iPTEN . Iinguqu kwijini ye-AKT1, ngakumbi, zinokunceda iiseli zomhlaza zikhule kwaye zahlukane ngokukhawuleza.
Into eyenziwa yiTruqap kukuthintela umsebenzi weproteni ebizwa ngokuba yi-AKT . Kufana nokucima iswitshi ekhawulezisa ukukhula kweeseli zomhlaza.
Ayipheleli apho. Iiseli zomhlaza ezixhomekeke kwiihomoni zixhomekeke kwiihomoni ezifana ne-estrogen egazini lethu ukuze zikhule. Yiyo loo nto iTruqap inikwa kunye nonyango lweehomoni olubizwa ngokuba yi-fulvestrant.
- I-Truqap: Ithintela iproteni ye-AKT eyonyusa izinga lokukhula kweeseli zomhlaza.
- I-Fulvestrant: Ithintela i-hormone estrogen ukuba ingafikeleli kwiiseli zomhlaza.
Ukuhlasela kumacala omabini ngale ndlela kunceda kakhulu ekulawuleni ukukhula kweeseli zomhlaza.
Ndingazi njani ukuba olu nyango lufanelekile kum?
Unyango lweTruqap lunokuba lufanelekile kuwe kwiimeko ezilandelayo:
- Umhlaza wakhoUkuba sele ikhulile, okanye isasazeke kwezinye iindawo zomzimba (i-metastatic) .
- Ukuba uvavanyo oluthile luqinisekisile ukuba iiseli zakho zomhlaza zinotshintsho oluchazwe apha ngasentla (PIK3CA, AKT1, PTEN) .
- Ukuba sele ufumene unyango lwehomoni, kwaye umhlaza ubuyile ngexesha okanye emva kolo nyango.
Okubaluleke kakhulu, ugqirha wakho we-oncologist uza kugqiba ukuba eli yeza lifanelekile na kuwe. Uza kuhlola utshintsho lwemfuza kumhlaza wakho aze ahlole imbali yakho epheleleyo yezonyango ukuze enze isigqibo sokugqibela.
Zithini iziphumo ebezingalindelekanga zeTruqap? Zingalawulwa njani?
Njengayo nayiphi na imithi, iTruqap inokubangela iziphumo ebezingalindelekanga. Ezinye zazo zinokuba yingozi. Ngoko ke kubalulekile ukuba uzazi ezi zinto.
Nazi iziphumo eziphambili kunye nento omele uyenze ukuba ziyavela.
| Imiphumela | Kwenziwe ntoni |
|---|---|
| Iswekile ephezulu egazini | Ukuba ufumana iimpawu ezifana nokunxanwa okungaqhelekanga, ukuchama rhoqo, okanye ukwehla kobunzima nangona usitya kakhulu, xelela ugqirha wakho ngoko nangoko . Uza kuvavanya iswekile yakho yegazi rhoqo aze enze nantoni na efunekayo ukulawula amanqanaba eswekile yakho. |
| Urhudo | Xelela ugqirha wakho kwangoko xa uqala ukuba norhudo. Sela iziselo ezininzi, ezifana namanzi kunye nejusi, ukuze uthintele ukuphelelwa ngamanzi emzimbeni. Ugqirha wakho uza kukunika amayeza afanelekileyo. |
| Iimpendulo zesikhumba | Ukuba ubona izilonda ezintsha eluswini, ukwanda kwezilonda ezikhoyo, ukuba bomvu kwesikhumba, umkhuhlane, amadyungudyungu emilebeni/amehlo/emlonyeni, amadyungudyungu esikhumba okanye ulusu oluxobukayoYazisa ugqirha wakho ngoko nangoko. Nguye oza kugqiba ukuba aqhubeke nokusebenzisa iyeza okanye atshintshe umthamo walo. |
Ukongeza kwezi, usenokuba nesicaphucaphu, ukuhlanza, ukudinwa, izilonda emlonyeni, kunye notshintsho kwezinye iziphumo zovavanyo lwegazi.
Okubaluleke kakhulu: Ungaze uyeke ukuthatha amayeza akho okanye utshintshe umthamo ngaphandle kwengcebiso kagqirha wakho. Ukuba uneempawu ezikukhathazayo, thetha naye ngazo.
Ngaba iTruqap iyasebenzisana nezinye amayeza okanye ukutya?
Ewe, eli linqaku elibaluleke kakhulu. I-Truqap inokunxibelelana namanye amayeza nokutya. Ngoko ke, kufuneka uxelele ugqirha wakho ngawo onke amayeza owasebenzisayo (kuquka amayeza ezinye izifo, iivithamini, kwaneemveliso zezityalo).
Oku kungenxa yokuba umzimba wethu usebenzisa i-enzyme ebizwa ngokuba yi -CYP3A ukuqhekeza eli yeza nokulisusa emzimbeni. Amanye amayeza nokutya kunokutshintsha indlela esebenza ngayo le enzyme ye-CYP3A.
- Ii-CYP3A Inhibitors: Ezi zithintela ukusebenza kwe-enzyme ye-CYP3A. Oku kunokubangela ukuba iTruqap ihlale emzimbeni ixesha elide kwaye kwandise umngcipheko weziphumo ebezingalindelekanga. Amanye amayeza okubulala iintsholongwane kunye ne-fungus awela kolu luhlu. Ngokukodwa, kufuneka uphephe ukusela ijusi yegrapefruit okanye igrapefruit ngelixa usebenzisa iTruqap.
- I-CYP3A Inducers: Ezi zisebenza ngokwandisa umsebenzi we-enzyme ye-CYP3A. Oku kunokubangela ukuba iTruqap isuswe emzimbeni ngokukhawuleza, nto leyo enciphisa ukusebenza kwayo. Amanye amayeza okubulala iintsholongwane (afana ne-rifampicin) kunye namanye amayeza e-HIV awela kolu didi.
Ngoko ke, ngaphambi kokuba uqalise naliphi na iyeza elitsha, qiniseka ukuba uthetha nogqirha wakho we-oncologist ngalo.
Uyazi njani ukuba iyeza liyasebenza?
Ugqirha wakho uza kujonga imeko yakho rhoqo. Uza kwenza iimvavanyo ezifana novavanyo lwegazi, ii-CT scans, kunye nee-MRI scans ukuvavanya ukuba iyeza lisebenza kakuhle kangakanani na. Okufuneka ukwenze kukuthatha amayeza kanye njengoko ugqirha wakho ekuxelele.
Umyalezo Wokuya Ekhaya
- I-Truqap (i-capivasertib) lunyango olujoliswe kumhlaza webele. Ijolise ngokukodwa kwiiseli zomhlaza, ngoko ke ayibangeli monakalo mkhulu kwiiseli ezisempilweni.
- Olu nyango lufanelekile kubantu abanomhlaza abaxhomekeke kwiihomoni (HR-positive), abanolaka, kwaye abanotshintsho oluthile kwimfuza (PIK3CA, AKT1, okanye PTEN).
- Njengoko iziphumo ebezingalindelekanga ezifana namanqanaba aphezulu eswekile egazini, urhudo, kunye nokusabela kolusu kunokwenzeka, xela ugqirha wakho naziphi na iimpawu ezingaqhelekanga ngoko nangoko.
- Ungaze uyeke ukuthatha amayeza okanye utshintshe umthamo ngaphandle kwengcebiso kagqirha wakho.
- Kubalulekile ukwazisa ugqirha wakho malunga nazo zonke ezinye iziyobisi kunye nezongezo zokutya ozithathayo.
