Ndikofunikira kwambiri kukhala pafupi ndi chipatala chomwe mudalandira chithandizo mwezi woyamba, ngakhale mutatuluka kuchipatala. Komanso,

• Wina ayenera kukhala nanu maola 24 patsiku kuti akuthandizeni ngati muli ndi zotsatirapo zina.
• Musayendetse galimoto kwa miyezi iwiri mutalandira chithandizo. Mukufuna wina kuti achite zimenezo.

Kodi zotsatirapo zake ndi ziti?

Pali mitundu iwiri ya zotsatira zoyipa zomwe zimapezeka kwambiri ndipo ziyenera kuganiziridwa bwino ndi mankhwalawa. Zotsatira zina zoyipa zimathanso kuchitika.

Kodi ubwino ndi kuchuluka kwa chithandizochi ndi kotani?

Mwachitsanzo, kafukufuku wa 2020 adawonetsa kuti ana opitilira 85% omwe adalandira chithandizochi cha khansa ya m'magazi (ALL) adachira kwathunthu atalandira chithandizo. Komanso, 60% ya iwo analibe khansa patatha chaka chimodzi. Koma ndikofunikira kukumbukira kuti iyi si njira yopambana 100% ya aliyense, koma njira yochiritsira aliyense.

Kodi muyenera kupita kwa dokotala liti?

Izi ndizofunikira kwambiri. Zina mwa zotsatirapo za CAR T-Cell Therapy, makamaka Cytokine Release Syndrome ndi mavuto a mitsempha, zitha kukhala zoopsa kwambiri .

Chithandizochi chikadali gawo latsopano lomwe likukulabe. Chifukwa chake ngati muli ndi khansa ya m'magazi, lankhulani ndi dokotala wanu ngati chithandizochi chili choyenera kwa inu.
