Kuyesa kwa CA 15.3 - ndi chiyani ndi momwe zimachitikira - Thanzi

Zamkati

Kuyezetsa kwa CA 15.3 ndiye mayeso omwe amafunsidwa kuti athe kuwunika momwe angathandizire komanso kuwunika momwe khansa ya m'mawere ibwerezedwere. CA 15.3 ndi mapuloteni omwe amapangidwa ndimaselo am'mabere, komabe, mu khansa kuchuluka kwa mapuloteniwa ndikokwera kwambiri, kugwiritsidwa ntchito ngati chikhomo.

Ngakhale amagwiritsidwa ntchito kwambiri mu khansa ya m'mawere, CA 15.3 itha kukwezedwa mumitundu ina ya khansa, monga m'mapapo, kapamba, ovary ndi chiwindi, mwachitsanzo. Chifukwa chake, iyenera kuyitanidwa limodzi ndi mayeso ena, monga kuyesedwa kwa ma molekyulu kuti muwone momwe majini amafotokozera khansa ya m'mawere ndi mayeso omwe amayesa estrogen receptor, HER2. Onani mayesero omwe amatsimikizira ndikupeza khansa ya m'mawere.

Ndi chiyani

Kuyesa kwa CA 15.3 makamaka kumawunikira kuyankha kwa chithandizo cha khansa ya m'mawere ndikuwunika ngati zingachitike. Mayesowa sanagwiritsidwe ntchito pakuwunika, chifukwa amakhala ndi chidwi chochepa komanso mwatsatanetsatane. Nthawi zambiri amalimbikitsidwa ndi dokotala kuti ayesere asanayambe kulandira chithandizo komanso milungu ingapo atachitidwa opaleshoni kapena kuyamba chemotherapy, kuti awone ngati chithandizo chikugwiradi ntchito.


Kuchuluka kwa puloteni iyi m'magazi kumawonjezeka mwa 10% ya amayi mgawo loyamba la khansa ya m'mawere komanso mwa azimayi opitilira 70% omwe ali ndi khansa patsogolo kwambiri, nthawi zambiri ali ndi metastasis, akuwonetsedwa kuti ayese azimayi omwe adalandira kale kapena omwe akudwala khansa.

Zatheka bwanji

Kuyesaku kumachitika kokha ndi magazi a munthuyo ndipo sikutanthauza kukonzekera kulikonse. Magaziwo amatengedwa ndikutumizidwa ku labotale kuti akayesedwe ndikuwunika. Njira zowunikira nthawi zambiri zimangokhala zokha ndipo zimapanga zotsatira zolondola komanso zodalirika munthawi yochepa.

Mtengo wokhudzana ndi mayesowa ndi 0 mpaka 30 U / mL, zomwe zili pamwambapa zikuwonetsa kale za vuto. Kuchuluka kwa CA 15.3 m'magazi, khansa ya m'mawere ndiyotukuka kwambiri. Kuphatikiza apo, kuwonjezeka kwapang'onopang'ono kwa mapuloteniwa kumatha kuwonetsa kuti munthuyo sakuyankha chithandizo kapena kuti zotupa zimayambiranso, zomwe zikusonyeza kuti ayambiranso.


Kuwonjezeka kwa CA 15.3 sikuwonetsa khansa ya m'mawere, chifukwa puloteni iyi imatha kukwezedwa mumitundu ina ya khansa, monga khansa yam'mapapo, yamchiberekero komanso yamtundu wina. Pachifukwa ichi, mayeso a CA 15.3 sagwiritsidwa ntchito poyang'anira, kungoyang'anira matendawa.
