Tunlaia kan sawi tak medical concept thar ber, Precision Medicine tia koh hi chu harsatna chinfelna atan a rawn lang chhuak a ni.
A awlsam zawngin, Precision Medicine chu eng nge ni?
Precision Medicine hi Sinhala tawngin "precision medicine" tia lehlin theih a ni. Mahse a thumal aiin a concept hriatthiam a pawimawh zawk.
Entirna awlsam tak hmangin i tan ang u. Store pakhatah kawr lei turin i kal ang tih han ngaihtuah teh. Kawr lian tak tak, "Small", "Medium", "Large" te pawh a awm nual. "Medium" chu i pick up a, i try leh ta a ni. A tight lutuk pawh a ni thei, a lian deuh pawh a ni thei, a sleeve pawh a sei lutuk thei bawk. Mahse duhthlan tur i neih loh avangin i lei ta a ni. Hei hi hmanlai "one-size-fits-all" tih dan a ni.
Tunah chuan puan siamtu tha tak hnenah i kal ang tih han mitthla teh. I tehna zawng zawng, i san zawng, i rih zawng, i kut sei zawng, leh i kekawr bul vel ang chi te chu a la vek a, i tan bik kawr a siamsak bawk. Engtiang chiahin nge mawi leh nuam takin i taksaah a in fit ang? Chu chu Precision Medicine hian a tum ber chu a ni.
Precision Medicine chu mi zawng zawng damdawi emaw, enkawlna inang emaw pek ai chuan, natna laka invenna tur enkawlna leh hmanraw tha ber ber thlan hi a ni.

Precision Medicine atang hian eng hlawkna nge kan hmuh?
He tunlai hmanraw hian damdawi lam a tidanglam dawn a ni. A hlawkna lian ber berte chu hetiang hi a ni:
- I tana damdawi dik tak, a dose dik tak: I genetic information hmangin i doctor chuan eng damdawi nge i tan a tha ber ang tih chiang takin a hre thei a, a side effects tlem ber a nei a, a pek tur dose dik tak pawh a hre thei bawk.
- Natna lo awm chhan hriatthiamna thuk zawk neih: Engvangin nge natna thenkhat chu thlah khat atanga thlah dangah an insem darh? Engvangin nge mi thenkhat chauhvin cancer an vei? Hetiang zawhna chhanna tur hian genetic information hian a pui hle a ni.
- Natna a lo thlen hmaa ven dan:I genetic test-na chuan nakin lawkah zunthlum, thinlung natna, a nih loh leh cancer chi khat i vei theihna chance a sang zawk tih a sawi thei a nih chuan, chutiang laka inven nâna i nunphung tihdanglam chu eng zât nge a hlu ang? Precision Medicine hi a kal dan tur a ni.
- Diagnosis dik zawk: A châng chuan, a lan chhuah dân inang lo mah se, a chhûng lamah chuan natna inang lo tak tak pahnih a awm thei. Genetic level-a test a nih chuan natna dik tak hriat theih a ni.
Eng field-ah nge Precision Medicine hman tawh?
Hei hi nakin lawka thil lo thleng tur chauh a ni lo. Khawvel ram changkang zawka doctor-te chuan he hmanrua hi kawng engemaw zatah hlawhtling takin an hmang tawh a ni. A bulpui thenkhat han thlir ila.
1. Cancer enkawl dan (Precision Oncology) .
Hei hi tun thlenga Precision Medicine hmanna lian ber leh hlawhtling ber a ni. Tun hma chuan cancer hi a lo chhuahna hmun a zirin kan thliar hrang thin a. Entirnan, "lung cancer" emaw "hnute cancer" emaw.
Mahse tunah chuan scientist te chuan hmun khata cancer lo awm pawhin molecular fingerprint hrang hrang an nei thei tih an hmuchhuak ta a ni . Kan kutziak ang bawkin. Chumi awmzia chu lung cancer vei pahnih hian an cancer cell-ah genetic change (mutations) hrang hrang an nei thei tihna a ni.
Chuvangin, Precision Oncology-ah chuan damlo tumor (biopsy) sample tlemte lak a ni a, a genetic changes te chu enfiah a ni. Tichuan, damlo chu chu genetic change bik chauh beitu damdawi (targeted therapy) pek a ni .
Rukru pawl pakhatin khawpui pakhat an rawn luhchilh lai han mitthla teh. Traditional method chu khawpui pum pui curfew hnuaia dah a, in tin check vek hi a ni. Hei hian mi sual lote pawh a nghawng a ni. Precision Medicine hi CCTV hmanga rukrute hi eng in nge an inthup tih chiang taka hriat a, chu inah chuan kal a, rukrute man ang mai a ni. Hei hian cell hrisel tak takte chu a tichhe tlem hle.
2. Cancer Immunotherapy hmanga enkawlna
Hei hi cancer enkawlna kawnga hmasawnna mak tak dang a ni. Kan taksa hian natna dotu sipai a nei a. Immune system kan ti a . He sipaite hian kan taksaa cell pangngai lo, chu chu cancer cell, kan taksaa lo thang lian te chu a hre thei a, a tichhia thei bawk.
Mahse cancer cell thenkhat chu an fing hle. An inthuam tha hle a, kan immune system atanga inthup an ni.
Immunotherapy hian kan taksa hriselna (immune system) te hi heng cancer cell thup te hi hriatchhuah leh beih theihna tura "training" hmangin hna a thawk a ni. Kan sipaite hnenah hmêlma thup hmu thei tur radar system thar pek ang mai a ni. Hei hian mahni taksa invenna hmangin cancer thunun emaw, tihdam emaw pawh kan nei thei ta a ni.
3. Pharmacogenomics chungchang
He thumal hi a harsa deuhin lang mahse, a concept hi a awlsam hle.
Pharmaco = damdawi (damdawi) .
Genomics = Genetics tih hi a ni
Chu chu i damdawi eite chunga i gene-te’n an chhân lêt dân zir chian tihna a ni.
Kan gene hi tlem a inang lo vek a, chuvangin damdawi pakhat hian kan taksaah hna a thawk dan a inang lo ang.
- Mi thenkhat taksa chu a chhe vek a, damdawi pakhat chu a bo nghal vat thin. An tan chuan normal dose hi a tawk lo mai thei.
- Midang taksa hian ruihhlo hi a ti chhe zawi hle. An tan chuan dose pangngai pawh hi toxic a ni thei.
Pharmacogenomics tih hian damdawi i pek hmain i genetic information tlemte chu thisen test awlsam tak hmangin i la a, chu damdawi chu i taksain engtin nge a tih ang tih i en hmasa phawt a ni. Hei hian i doctor chuan i tana damdawi leh a hman dan tur dik ber a hriat theih phah a ni. Hei hian duh loh zawng side effect leh enkawlna hlawhtling lo tak takte pumpelh nan a pui thei a ni.
4. Natna hmuh tur awm lo
Khawvelah hian genetic disease hi a tlem hle a, a danglam bik hle bawk. A châng chuan doctor-te pawhin he natna thlentu dik tak hi an hre thei lo. Kum tam tak chhung damdawi inah kal a, test chi hrang hrang an neih hnua he natna vei chhungkua an awm a, mahse he natna hi eng nge a nih an hre thei lo.
Precision Medicine hian hetiang mite tan hian beiseina nasa tak a thlen a ni. Tunah chuan damlo pakhat genetic makeup zawng zawng (Genomic Sequencing) enfiah a, chu DNA chain-ah chuan "letter mistake" (genetic mutation) tlemte tak tak hmuh theih a ni ta. Chu tihsual tenau tak chu natna pumpui thlentu a ni. He natna thlentu dik tak an hriat chian chuan zirchiangtute tan a damdawi zawn a awlsam phah thin.
Precision Medicine hian engtin nge nakin lawkah kan nun a tihdanglam ang?
He technology hi a la bul tanna a la ni a, mahse a theihna chu a nasa hle. Nakin lawkah doctor i pan hunah i thisen test result pangngai nen i genetic information a nei ang.
- Damdawi a pek hma che chuan doctor chuan report chu a en a, "Aw... he damdawi hi a allergy a nei mai thei a, chuvang chuan hei hi kan pe ang," tiin a rel a.
- I chhungkuaa tumahin an neih loh natna i neih chuan, a chhan chu boruak nghawng vang nge, i nunphung tihsual vang nge, a nih loh leh genetic change thar a nih leh nih loh i hre thei ang.
- Kan vai hian kan tana danglam bik health plan kan siam thei vek dawn a ni.
Hei hi science fiction a ni tawh lo. Hei hi damdawi hmalam hun chu a ni. Heng technology te hi Sri Lanka-a lo kal a, thil awmze nei tak a nih theih nan hun engemaw chen a la ngai dawn a ni. Mahse, tunah chuan hetiang targeted therapies hi kan rama cancer vei thenkhat tan chuan eng emaw chen chu hman a ni tawh a ni. Chuvang chuan hei hi kan hriat chian a pawimawh hle a ni.
Take-Home Thuchah a ni
- Precision Damdawi hman danTunlai damdawi lam kalphung a ni a, damdawi lam hawia mi zawng zawng tan pakhat chauh hman a ni lo va, chu ai chuan mimal tinte tana remchang tur enkawlna a thlang zawk a ni.
- Chumi atân chuan thil pathumte chu ngaihtuah vek a ni: i genes , i chhehvêl, leh i nun dân .
- Hetiang method hi oncology , immunotherapy , natna hlauhawm tak tak hmuhchhuahna kawngah te hlawhtling takin hman a ni tawh a ni .
- Pharmacogenomics tih field hmangin he method hian i genes nena inmil leh side effects tlem ber nei damdawi dose dik tak pe turin a pui a ni.
- Hei hi field hmasawn zel ni mah se, nakin lawkah damdawi lam thil tihdanglam theihna a nei a ni. Ni khat chu enkawlnate chu a hlawk zawk ang a, a him zawk ang a, mimal takin a siam ang.
