Chhungkaw member emaw, thian emaw chuan thisen lama harsatna lian tak emaw, thisen cancer emaw a vei tih doctor hnen atanga kan hriat hian hlauhna leh lungkhamna a awm tih kan hre vek a ni. Mahse tunlai damdawi lama hmasawnna avang hian hetiang natna tidam thei damdawi chak tak tak a awm a. Chutiang nunna chhanhim thei damdawi pakhat chu "Allogeneic Stem Cell Transplant" an ti a. A hming hi thil buaithlak tak angin lang mah se, he thila thil thleng hi awlsam takin han sawi ila.
Allogeneic stem cell transplant hi eng nge ni tak tak?
A awlsam zawngin, hei hian i taksa atanga stem cell natna nei, thawk tha lo tak takte chu paih chhuakin, mi dang (donor) atanga stem cell hrisel, inmil tak tak hmanga thlak a huam a ni.
Tunah chuan hei hi tlem han sawifiah leh ila.
- Stem Cells: Heng hi "mother cells" kan ti thei bawk a, a chhan chu heng cell te hi kan taksa chhunga thisen cell dang zawng zawng (red blood cells, white blood cells, platelets) siamtu factory ang an nih vang a ni. Heng stem cells te hi kan ruhroah hian a awm tam ber.
- Allogeneic: He thumal hi "midang hnen atanga dawn" tihna a ni. Chumi awmzia chu enkawlnaah hian nangmah ni lovin, donor hrisel, inmil tak atanga cells te hman a ni tihna a ni.
Kan ruhro hi lo tha tak, lei tha tak nei ang mai a ni ang tih han ngaihtuah teh. Hemi kawngah hian kan thisen cell te hi a thang lian thin. Mahse leukemia ang natnaah chuan he lo hi a chhe vek a, thlai tha tak tak aiah buh (cancer cells) a lo thang lian thin. Chuvangin, he enkawlnaah hian chu lei chhe tawh (ruh natna natna) chu paih vek a ni a, lei thar, hrisel, tha tak (donor’s stem cells) hmanga thlak a ni. Tichuan, chu lei tharah chuan thisen cell hrisel tak tak a lo thang tan ta a ni.
He enkawlna hi thiltithei tak a ni a, natna khirh tak tak thenkhat a tidam vek thei a ni. Doctor-te chuan enkawlna dang a hlawhchham hunah emaw, natna a lo awm leh hunah emaw he enkawlna hi an hmang tlangpui.
He enkawlna hi eng dinhmun chi hrang hrangah nge hman a nih?
Thisen leh immune system nena inzawm natna atan hman a ni fo. Natna lian tham thenkhatte chu hetiang hi a ni.
| Damdawi lam dinhmun | A sawifiahna awlsam tak |

- Test hi liver leh kidney function enfiah nan an ti thin .
- Bone Marrow Biopsy: Cancer i neih chuan bone marrow sample te tak te la in test a ni a, natna awm dan leh a lo let leh theihna tur te an zirchiang thin.
Heng test zawng zawng hi tih zawh a nih a, candidate tha tak i nih thu hriat chian a nih hnuah, enkawlna atana pawimawh ber, "pre-transplant conditioning" tia koh chu a intan ta a ni. Hei hian taksa pum puiah chemotherapy sang tak emaw, radiation therapy emaw a huam a ni. Hei hi hun harsa tak a ni thei. Mahse a pawimawh hle.
Engvangin nge he pre-treatment hi a pawimawh em em?
- I taksaa cancer cell la awm zawng zawng a tichhia a ni.
- I ruhro atanga cell hlui, natna nei te chu a paih chhuak a, cell thar lo lut tur leh lo thanglian theihna tur hmun a siamsak bawk.
- Hun engemaw chen chu i immune system a tichak lo. Hei hi i taksain cell pek tharte a beih loh nan leh a hnawl loh nan tih a ni.
He enkawlna atan hian kar khat emaw kar hnih emaw chhung damdawi inah i awm a ngai dawn a ni.
Cell transplant ni hian eng nge thleng?
Cell transplantation kalphung hi a takah chuan a awlsam hle a, a hrehawm lo , thisen pek ang bawkin.
Medical team chuan i rilru chunglam vein lian takah special tube an dah ang. Hei hi Central Venous Catheter (CVC) an ti a. Donor atanga stem cell hrisel tak tak awmna bag chu he tube nen hian a inzawm a ni. Chumi hnuah chuan cell te chu zawi zawiin i taksaah te, i thisen kaltlangin te, i ruhroah te, saline solution ang maiin an lut ta a ni.
Hetiang hian minute 30 atanga darkar khat vel a awh thin. Hemi chhung hian medical team te chu i bulah ṭhuin i thisen sang leh heart rate an enfiah ang. A châng chuan, side effect tenau te a awm thei bawk.

- A khawsik a ni
Mahse hengte hi a pawi lo tlangpui.
Enkawl hnuah eng nge thleng?
Recovery period pawimawh ber chu stem cell transplant hnuah a intan thin. Damdawi inah emaw, a bulah emaw kar tlemte dang i awm a ngai dawn a ni.
- Immune control: I taksain cell thar a beih loh nan leh cell tharin i taksa a beih loh nan immunosuppressants pek chhunzawm zel i ni ang.
- Thisen pek: Stem cell tharte hian hna an thawk tan a, red cell leh platelet thar an siam theih nan hun engemaw chen a ngai a ni. Chumi hun chhung chuan thisen pek a ngai mai thei.
- Infection laka invenna: Hetih hun chhung hian I immune system a chak lo hle a, chuvangin bacteria leh viral infection laka invenna hi a bik takin ngaihven a ni.
Cell tharte chu ruhro (bone marrow)-a kal a, chutah chuan an awm a, thisen cell thar siam tan dan chu "engraftment" an ti. Hei hian ni 10 atanga ni 14 vel a daih thei.

"Allogeneic" leh "autologous" transplant inthlauhna
Autologous stem cell transplant tih pawh i hre tawh mai thei. An pahnih inthlauhna ber chu cell awmna hmun a ni.
- Allogeneic: Cell hi mi dang (donor) atanga lak chhuah a ni.
- Autologous: Cell te hi damlo atanga lak chhuah a ni . Chumi awmzia chu damlo ngeiin a stem cell hrisel tak tak te chu an la khawm hmasa a, chumi hnuah high-dose chemotherapy an pek hnuah an pe let leh tihna a ni.
Allogeneic transplant hian nunna atana hlauhawm natna thenkhat chu a tidam vek thei a ni. Vawi tam tak chu heng nunna chhanhim thei transplant te hi kan la tawn ngai loh donor hriat loh ten an ti thin. A châng chuan chhûngkaw member-te chu thilpek petu an lo ni ṭhîn. He enkawlna hian hlauhawmna a neih laiin, a hlawkna pawh a sang hle. I doctor chuan heng zawng zawng hi a hrilhfiah ang che a, i tana tha ber tur thutlukna siam turin a pui ang che.
Take-Home Thuchah a ni
- Allogeneic stem cell transplant chu ruh natna nei, donor hrisel tak atanga stem cell hmanga thlak a ni.
- Hei hi thisen natna khirh tak tak, leukemia, lymphoma, leh aplastic anemia te tan damdawi chak tak a ni.
- Inenkawl hmain chemotherapy sang tak emaw, radiation therapy emaw hmanga taksa buatsaih a pawimawh hle.
- Enkawlna hnua harsatna awm thei ber chu Graft vs. Host Disease (GVHD) a ni a, hei leh hri kai chhinchhiahna te hi hriat reng a pawimawh.
- Hei hi damna rei tak a ni a, harsatna i neih chuan doctor emaw medical team emaw hriattir nghal a pawimawh hle.
