Lasers mu Chithandizo cha Khansa
Kodi laser kuwala ndi chiyani?
Mawu oti "laser" amatanthauza kukulitsa kwamphamvu pakulowetsedwa kwa radiation. Kuwala wamba, monga kuja kochokera ku babu yoyatsa, kumakhala ndi kutalika kwa mawonekedwe ake ambiri ndipo kumafalikira mbali zonse. Kuunika kwa Laser, komano, kumakhala ndi mawonekedwe ake enieni. Imayang'anitsitsa mumtengo wopapatiza ndipo imapanga kuwala kwambiri. Kuwala kwamphamvu kumeneku kungagwiritsidwe ntchito kudula chitsulo kapena kuumba diamondi. Chifukwa lasers amatha kuyang'ana molondola pazigawo zing'onozing'ono, itha kugwiritsidwanso ntchito pochita opareshoni yeniyeni kapena kudula minofu (m'malo mwa scalpel).
Kodi laser therapy ndi chiyani, ndipo imagwiritsidwa ntchito bwanji pochiza khansa?
Laser therapy imagwiritsa ntchito kuwala kwamphamvu kwambiri pochiza khansa ndi matenda ena. Lasers itha kugwiritsidwa ntchito kupeputsa kapena kuwononga zotupa kapena zophuka zoyambilira. Lasers amagwiritsidwa ntchito kwambiri pochiza khansa yapadera (khansa yapadziko lonse lapansi kapena zotchingira ziwalo zamkati) monga khansa yapakhungu yapakhungu yapansi komanso magawo oyambilira a khansa ina, monga khomo lachiberekero, penile, nyini, vulvar, ndi khansa ya m'mapapo yosakhala yaying'ono.
Lasers amathanso kugwiritsidwa ntchito kuthana ndi zizindikilo zina za khansa, monga kutuluka magazi kapena kutsekeka. Mwachitsanzo, ma lasers atha kugwiritsidwa ntchito kupeputsa kapena kuwononga chotupa chomwe chikulepheretsa trachea (chopepera) kapena kholingo la wodwalayo. Lasers itha kugwiritsidwanso ntchito kuchotsa polyp polyps kapena zotupa zomwe zikuletsa m'matumbo kapena m'mimba.
Mankhwala a Laser atha kugwiritsidwa ntchito payekha, koma nthawi zambiri amaphatikizidwa ndi mankhwala ena, monga opaleshoni, chemotherapy, kapena radiation radiation. Kuphatikiza apo, lasers amatha kusindikiza kumapeto kwa mitsempha kuti achepetse kupweteka pambuyo pochitidwa opaleshoni ndikusindikiza zotengera zam'mimba kuti muchepetse kutupa ndikuchepetsa kufalikira kwa ma cell a chotupa.
Kodi mankhwala a laser amapatsidwa bwanji kwa wodwala?
Mankhwala a Laser nthawi zambiri amaperekedwa kudzera mu endoscope yosinthasintha (chubu chowonda, chowunikira chomwe chimayang'ana ziwalo zamkati mwa thupi). Endoscope ili ndi ulusi wowoneka bwino (ulusi woonda womwe umatulutsa kuwala). Amalowetsedwa kudzera potsegula m'thupi, monga pakamwa, mphuno, anus, kapena nyini. Kuwala kwa Laser kumapangidwanso kuti kudule kapena kuwononga chotupa.
Laser-induced interstitial thermotherapy (LITT), kapena interstitial laser photocoagulation, imagwiritsanso ntchito lasers kuchiza khansa zina. LITT ndi ofanana ndi khansa yotchedwa hyperthermia, yomwe imagwiritsa ntchito kutentha kuchepetsa zotupa powononga kapena kupha ma cell a khansa. (Zambiri zokhudzana ndi hyperthermia zimapezeka mu pepala la NCI Hyperthermia mu Cancer Treatment.) Pa LITT, fiber yolumikizidwa imayikidwa mu chotupa. Kuwala kwa Laser kumapeto kwa CHIKWANGWANI kumakweza kutentha kwa zotupazo ndikuwononga kapena kuwononga. LITT nthawi zina amagwiritsidwa ntchito pochepetsa zotupa m'chiwindi.
Photodynamic therapy (PDT) ndi mtundu wina wa chithandizo cha khansa chomwe chimagwiritsa ntchito lasers. Mu PDT, mankhwala ena, otchedwa photosensitizer kapena photosensitizing agent, amalowetsedwa mwa wodwala ndikulowetsedwa ndi maselo mthupi lonse la wodwalayo. Pakatha masiku angapo, wothandizirayo amapezeka makamaka m'maselo a khansa. Kuwala kwa Laser kumagwiritsidwa ntchito kuyambitsa wothandizirayo ndikuwononga ma cell a khansa. Chifukwa photosensitizer imapangitsa khungu ndi maso kuzindikira kuwala pambuyo pake, odwala amalangizidwa kuti azipewa kuwala kwa dzuwa komanso kuwala kwamkati nthawi imeneyo. (Zambiri pa PDT zimapezeka mu pepala la NCI la Photodynamic Therapy for Cancer.)
Ndi mitundu iti ya lasers yomwe imagwiritsidwa ntchito pochiza khansa?
Mitundu itatu ya ma lasers imagwiritsidwa ntchito pochiza khansa: laser dioxide (CO2) lasers, argon lasers, ndi neodymium: yttrium-aluminium-garnet (Nd: YAG) lasers. Zonsezi zimatha kuchepa kapena kuwononga zotupa ndipo zitha kugwiritsidwa ntchito ndi ma endoscopes.
CO2 ndi argon lasers amatha kudula khungu popanda kulowa m'malo ozama. Chifukwa chake, atha kugwiritsidwa ntchito kuchotsa khansa yapadera, monga khansa yapakhungu. Mosiyana ndi izi, laser ya Nd: YAG imagwiritsidwa ntchito kwambiri kudzera mu endoscope pochizira ziwalo zamkati, monga chiberekero, minyewa, ndi khola.
Nd: Kuwala kwa laser kwa YAG kumathanso kuyenda kudzera mu ulusi wopanga kumadera ena a thupi nthawi ya LITT. Argon lasers nthawi zambiri amagwiritsidwa ntchito kuyambitsa mankhwala omwe amagwiritsidwa ntchito mu PDT.
Kodi maubwino a laser therapy ndi ati?
Lasers ndi olondola kwambiri kuposa zida zamankhwala zochitira opaleshoni (scalpels), chifukwa chake samawononga pang'ono matupi abwinobwino. Zotsatira zake, odwala nthawi zambiri samamva kupweteka pang'ono, kutaya magazi, kutupa, ndi zipsera. Ndi mankhwala a laser, ntchito nthawi zambiri zimakhala zazifupi. M'malo mwake, mankhwala a laser amatha kuchitira odwala mopitilira kunja. Zimatenga nthawi yocheperako kuti odwala azichiritsa atachitidwa opareshoni ya laser, ndipo samakonda kutenga matenda. Odwala ayenera kufunsa omwe amawapatsa zaumoyo ngati kuli koyenera kulandira mankhwala a laser.
Kodi zovuta za laser therapy ndi ziti?
Chithandizo cha Laser chimakhalanso ndi zoperewera zingapo. Madokotala ochita opaleshoni ayenera kukhala ndi maphunziro apadera asanakwane mankhwala a laser, ndipo ayenera kutsatira mosamalitsa chitetezo. Mankhwala a Laser ndiokwera mtengo ndipo amafuna zida zazikulu. Kuphatikiza apo, zovuta zamankhwala amtundu wa laser sizingatenge nthawi yayitali, motero madokotala amayenera kubwereza chithandizo cha wodwalayo kuti apindule ndi zonse.
Kodi tsogolo lamankhwala amtundu wa laser ndi lotani?
M'mayeso azachipatala (kafukufuku), madotolo akugwiritsa ntchito lasers pochiza khansa yaubongo ndi prostate, pakati pa ena. Kuti mudziwe zambiri zamayeso azachipatala, pitani ku NCI's Cancer Information Service ku 1-800–4-CANCER (1-800-422-66237) kapena pitani patsamba loyesa matenda a NCI.
