Cancer enkawlna lama hmasawnna thar: VMAT technology chungchang i zir dawn em ni? (Volumetric Modulated Arc Therapy hmanga enkawlna) tih a ni.

Nangmah emaw, i hmangaih tak emaw cancer vei tih i hriat chuan hlauhna leh lungkhamna i neih chu thu hmanga sawi a harsa hle. Tin, chutah chuan enkawlna chungchang i hriat chuan "radiation therapy" chungchang i hriat chuan i hlau lehzual mai thei bawk. Mahse medical science hi nitin a tha chho zel a. Vawiin hian chutiang enkawlna kawng hmasawn tak, rang tak tak pakhat, cancer cell chauh target a, cell hrisel tihchhiatna nasa taka tihtlemtu chungchang kan sawi dawn a ni. Hei hi VMAT an ti a.

Chuti a nih chuan, he VMAT hi eng nge ni?

A awlsam zawngin VMAT hi ‘Volumetric Modulated Arc Therapy’ tih acronym a ni. Hei hi cancer cell tihhlumna atana hman thin radiation therapy hmasawn tak a ni. A dik zawka sawi chuan External Beam Radiation Therapy (EBRT) chi khat a ni. Chumi awmzia chu i taksaah radioactive material engmah inject a ni lo tihna a ni. Chuvangin enkawl lai emaw, enkawl hnuah emaw i taksa atanga radiation chhuak tur ngaihtuah a ngai lo.

I khumah i mut lai hian machine lian tak chu zawi zawiin i chhehvelah a rawn inher a, radiation beam-te chu a target chhunzawm zel a, cancer awmna hmun chauh a target ang tih han ngaihtuah teh. Chu chu VMAT technology hmanga thil thleng chu a ni.

Hei hi radiation hmanga enkawl dan dang, IMRT (Intensity-Modulated Radiation Therapy) atanga advanced version a ni. IMRT-ah chuan radiation beam lian tak pakhat aiah hian radiation beam tenau zawk tam tak, intensity hrang hranga awm tam tak chu tumor-ah hian a thleng a ni. Hei hian tumor chhehvela tissue hrisel tak takte chhiatna nasa takin a ti tlem a ni . VMAT-ah pawh hetiang bawk hian machine chu a inher chhunzawm zel laiin a thleng a, chuvangin enkawlna chu chiang tak leh rang takin tih theih a ni .

VMAT enkawlna hi eng cancer chi hrang hrang atan nge hman?

VMAT technology dik tak a nih avangin cancer tumor, a pianzia danglam tak nei emaw, kan taksa peng pawimawh tak tak hnaih taka awm emaw enkawlna atan chuan solution tha tak a ni. Entirnan, i oncologist chuan he hmanrua hi taksa peng pakhat vel a cancer lo thang lian enkawl nan a rawt thei ang.

VMAT hmanga enkawlna hi a hnuaia cancer chi hrang hrang tan hian hman a ni ber.

Engtin nge hei hian hna a thawh? Enkawl hma hian eng nge thleng thin?

VMAT enkawl dan hi ruahmanna fel tak a ni. Step pawimawh engemaw zat a huam a ni.

1. Enkawl dan tur ruahmanna (Planning & Simulation) .

Hei hi a pawimawh ber a ni. I medical team chuan i taksa chu three-dimensional (3D) image an la hmasa ang. Hei hi CT scan hmanga tih a ni tlangpui a, mahse a chang chuan MRI emaw PET scan emaw hmanga tih a ni. Heng thlalakte hian cancer awmna hmun dik tak, a lian leh te, a pianzia leh a chhehvela taksa peng hrisel eng pawh, radiation laka venhim ngai te chu a hriat theih nan a pui ang.

Tichuan planning session "simulation" tih a awm bawk. Hetah,

• Treatment couch-ah hmun dik takah dah i ni ang a, radiation beam chu cancer chu a tawk chiah theih nan dah i ni ang.
• I vunah hian temporary marker emaw permanent marker emaw, tattoo te tak te ang chi emaw hmangin cancer awmna hmun dik tak chu i chhinchhiah thei a ni.
• I taksa tana siam bik mold emaw mask emaw i hmang thei bawk a, chu chu enkawl laiin che lovin i dinhmun ang chiah a ni.

He ruahmanna siam hi ni khat emaw ni engemaw zat emaw a ni thei a, a chhan chu enkawlna chu i cancer pianzia dik tak ang zela siam a ngai a, pencil tip (2.5 x 5 millimeters) ang maia te radiation beam hmanga siam a ngai a ni.

2. VMAT neih chhung hian

Radiation therapist chuan planning session chhunga i dinhmun ang chiah khan treatment bed-ah a dah ang che. Chumi hnuah chuan radiation pe chhuaktu machine, ``LINAC - Linear Accelerator'' an tih chu room hran atang hian a control ang. Microphone hmangin i biak theih ang.

Treatment a tan chuan LINAC machine chu zawi zawiin i chhehvelah a rawn inher kual vel a. A inher chhoh zel chuan radiation beam chi hrang hrang leh chakna hrang hrang te chu tumor lam hawi a ni. Heng radiation beam te hi i hre lo ang a, natna pawh i hre lo ang. Radiation therapist chuan computer screen-ah engkim uluk takin a enfiah vek ang.

Treatment session pumpui hi minute 20 vel ni mahse, a takah chuan radiation hi hun rei lote chhung, minute hnih vel a ni. Hun dang zawng chu position dik taka siam nan hman a ni.

3. Enkawl zawh hnu (VMAT hnu) .

Treatment session a zawh chuan in lamah i haw thei a, nitin hnathawh dan pangngai angin i thawk leh thei bawk.

VMAT enkawlna hian eng hlawkna nge a neih?

VMAT enkawlna hian thatna lian tak pahnih a nei a, chungte chu dikna leh chakna te an ni.

Side effect a awm em?

VMAT hmanga enkawlna hian tissue hrisel a tihchhiat tlem avangin side effects a awm theihna pawh a tlem hle. Mahse, cell hrisel tak takte chhiatna engemaw zat chu pumpelh theih a ni lo. Side effect a awm leh awm loh, leh eng nge a nih tih hi taksa enkawl mek hmun azirin a inang lo .

Mi tinin kan tawnhriat a inang lo. Mi thenkhat chu enkawl an nih veleh an dam nghal mai thei. Mi dangte chu an dam kim theih nân thla engemaw zât a la ngai thei bawk. I hriselna dinhmun a zirin eng nge i beisei tur tih doctor zawt rawh.

I enkawl hnuah follow-up appointment pek i ni ang. Heng appointment zawng zawngah hian tel vek ngei ang che. I doctor hnenah symptom emaw side effect emaw i neih theih dan tur sawipui rawh.
