Kunzwisisa Kubudirira Kwemarudzi Emajini eB-ALL Evakuru

Ndira 15, 2025, Shanghai - Ongororo ichangobva kuburitswa mujenari Ropa inopa ongororo yakadzama yemhando dzemajini dzeB-cell Acute Lymphoblastic Leukemia (B-ALL), chirwere chegomarara chisingawanzoitiki uye chine njodzi chine fungidziro yakaderera muvanhu vakuru kana tichienzanisa nevana. Mumakumi maviri emakore apfuura, tsvakiridzo ye genomic yakaratidza mhando dzemajini dzinopfuura makumi maviri dzakasiyana dzeB-ALL, imwe neimwe ine zvayakanakira zvakasiyana pamhinduro yekurapwa uye fungidziro.

Kunyange hazvo nzira dzekurapa dzinoenderana nenjodzi dzemajini dzakachinja nzira dzekurapa muvana vane B-ALL, mamiriro emajini evakuru veB-ALL haasati anyatsonzwisiswa. Ongororo iyi inoratidza kunzwisisa kwakakosha mukusiyana-siyana kwemajini muvarwere vakuru uye inosimbisa kukosha kwekubatanidza kuongororwa kwemajini mukuongorora kwakajairika kuti nzira dzekurapa dzakagadzirirwa munhu mumwe chete.

Zvakawanikwa Zvikuru:

1. Philadelphia Chromosome-Positive (Ph+) B-ALL:
   Ichimiririra rudzi rwakajairika muvanhu vakuru, kunyanya kune avo vane makore anopfuura 55, Ph+ B-ALL inobuda muBCR::ABL1 fusion gene. Nhoroondo yakabatana nekutadza kufungidzira, kubatanidzwa kwetyrosine kinase inhibitors (TKIs) uye ma antibodies e monoclonal, akadai seblinatumomab, kwakavandudza zvakanyanya mwero wekurarama. Humbowo huri kubuda hunoratidza kusiyana kukuru kwezvipenyu mukati mePh+ B-ALL, zvichisimbisa kukosha kwemamaki emolecular seIKZF1 pakupatsanura njodzi uye kuronga kurapwa.

2. Kuchinja kweropa muropa kushoma uye TP53:
   Kuderera kweropa muropa, kunoratidzwa nehuwandu hwemachromosomes hwe30-39, kwakawanda muvanhu vakuru uye kunoenderana nemigumisiro yakaipa. Zvidzidzo zvechangobva kuitwa zvinoratidza basa rekuchinja kweTP53, kunowanzobatanidzwa ne clonal hematopoiesis, mukutungamira rudzi urwu rwenjodzi huru. Zvakawanikwa zvinoratidza kuti kuchinja uku hakungokanganisi kutanga kwechirwere chete asi kunogonawo kubatsira panzira dzekurapa mushure mekuregererwa.

3. Kugadziriswazve kweKMT2A:
   Kazhinji kucherechedzwa muvanhu vakuru vane B-ALL, kugadziriswa kweKMT2A kwakabatana nemigumisiro yakaipa. Nzira itsva dzekurapa, dzakadai sedzinodzivirira menin, dzine vimbiso yekugadzirisa kuramba kurapwa kwerudzi urwu.

4. Mhando Dzemhando Dzisingawanzoonekwi uye Mishonga Ichiri Kubuda:
   Mhando diki dzakadai seTCF3::PBX1 uye TCF3::HLF fusions, kunyange hazvo zvisingawanzoitiki, zvinoratidza kusiyana kwakakosha kwehupenyu uye kwekiriniki. Ruzivo rwunokurudzira rusati rwatanga kukiriniki runoratidza kuti mishonga mitsva senge venetoclax neBET inhibitors inogona kushandiswa, zvichigadzira nzira yekurapa kutsva.

Zvinokonzera Kurwara:

Ongororo iyi inoda kuti nzira dzepamusoro dzekuongorora majini dziitwe nguva dzose, kusanganisira kutevedzana kwemagwaro ese, kuti tizive mhando dzemajini emunhu mukuru anonzi B-ALL. Nzira iyi inogona kuwedzera kupatsanurwa kwenjodzi, kutungamira sarudzo dzekurapa, uye kuvandudza kutariswa kwezvirwere zvishoma (MRD).
