Cancer dona a harsatzia leh a harsat zia chu kan hre vek. Mahse nitin damdawi lam thiamna a lo thang chho zel a, enkawlna thar leh thil thar siam chhuah a ni chho zel a. Vawiin hian mi tam takin beiseina sang tak an neih, mahni taksa cell hmanga cancer enkawl dan thar kan sawi dawn a ni. Hei hi TIL Therapy an ti a.
A awlsam zawngin, TIL Therapy chu eng nge ni?
Okay, hei hi awlsam takin i vawng ang. Immunotherapy tih hi i hre tawh ngei ang . Kan taksa hriselna (immune system), natna dotu kan sipai, cancer cell tihchhiat pui tura puih hi a ni. TIL therapy hi chutiang immunotherapy pakhat a ni.
Hei hian kan taksaah hian immune cell chi khat bik, chak tak a hmang a. Heng cell te hi tumor-infiltrating lymphocytes , a tawi zawngin TILs an ti a.
Ngaihtuah teh, kan taksa hian sipai chi hrang hrang (immune cells) a nei a, chu chuan kawngpuiah natna zawngin an patrol thin. Mahse heng sipai TIL tia koh te hi an danglam bik zawk. Tumor-ah an lut nghal a, chu chu an rawn lut a, chu cancer cell-te chak lohna chu eng nge ni tih leh tihchhiat dan tha ber chu eng nge ni tih chiang takin an zir chhuak a ni. Hmelma camp chhunga rawn lut leh scout-tu special forces team ang mai an ni.
Chuti a nih chuan eng nge buaina awm? Buaina chu, kan immune system hian heng sipai fing tak tak, a nih loh leh TIL te hi a siam tling thei lo. Mi tlemte tan chuan he cancer hi anmahni chauha do a, hnehna chan a ngai a ni.
Chutah chuan TIL therapy a lo lut a, he enkawlna hian a tih chu i taksaa TIL sipai fing ber berte chu a chhuah chhuak a, maktaduai tam takin a tipung a, sipai chak tak a siam a, chutah chuan i taksaah dah leh a ni. Tichuan he sipai ropui tak hian a kal a, cancer cell te chu a tichhia a ni.
He damdawi hi eng cancer chi hrang hrangah nge hman theih ang?
Kum 2024 atang khan U.S. Food and Drug Administration (FDA) chuan TIL therapy lifileucel (Amtagvi®) tih chu a pawm tawh a ni. A bik takin vun cancer chi khat melanoma tih enkawlna atana siam a ni . Mahse, melanoma chi hrang hrang tan a tha lo. He enkawlna hi:
- Surgery ringawt pawha tihdam theih a ni lo, .
- Kan taksa peng dangah cancer a darh tawh (metastatic cancer), .
- Tin, oncologist-te’n an pek hmasak ber standard treatment dawng lote tan pawh.
Hetiang dinhmun hi i neih chuan he enkawlna atan hian candidate tha tak i ni mai thei. Chumi chungchang chu i doctor nen in sawipui tur a ni.
Hei bakah hian doctor leh zirchiangtute chuan cancer chi dang engemaw zat tan TIL therapy hlawhtlinna an zirchiang mek a, chung zingah chuan:
- Hnute cancer a ni
- Cervical cancer a ni
- Colon cancer a ni
- Lu leh kawng cancer a ni
- Cell tenau lo lung cancer
Engtin nge he enkawlna hian hna a thawh? Step khat hnu step khatin i zir ang u.
Hei hi ni khata thil thleng a ni lo. A pawimawh ber chu nangmah ngeiin i TIL cells te chu nangmah ngeiin i pe let leh thin. Mahse chutiang dinhmun kan thlen hma chuan step engemaw zat a awm. Chu step te chu a hnuaia mi ang hian i en ang u.

| 4. Taksa hnena TIL cell pek (TIL transfusion) . | Tunah hi a pawimawh ber a ni. Lab-a siam i TIL cells te chu saline ang maiin i taksaah i inject a ni. Hei hi vawi khat chauh tih a ni. Darkar hnih vel a ni. |
| 5. Interleukin-2 infusion hmanga tih a ni | TIL cells pek a nih hnuah damdawi pakhat Interleukin-2 (IL-2) an tih chu ni thum atanga ni nga chhung pek i ni ang. Hei hi immunotherapy a ni bawk. Hei hian a tih chu taksaa TIL cells infuse tawhte chu a activate a, cancer bei turin a fuih a ni. |
Enkawlna i neih zawh chuan damdawi inah ni engemaw zat i awm leh a ngai dawn a ni. Chumi chhung chuan medical team chuan i taksain enkawlna a dawn dan chu uluk takin an enfiah ang. Chumi hnuah chuan damdawi in atanga awlsam taka kal theihna hmunah kar engemaw zat awm turin thurawn i dawng ang. Hei hi side effect i neih chuan rang taka enkawlna i hmuh theih nan a ni.
He enkawlna famkim hian eng chen nge a daih?
TIL therapy hi vawi khat enkawlna a ni . Mahse, cancer lak chhuah ni atanga cell siam ni thlengin, enkawl i nih thlengin, i dinhmun pangngaia i awm leh thlengin a kalphung zawng zawng hi kar 10 vel a ni thei Damdawi inah kar hnih vel i awm a ngai dawn a ni.
Hei hian eng hlawkna leh hlauhawmna nge a neih?
He enkawlna hlawkna te
Hei hi thiltithei tak, mimal taka enkawlna a ni.
