Kupita patsogolo kwatsopano pa chithandizo cha khansa: Tiyeni tiphunzire za ukadaulo wa VMAT? (Volumetric Modulated Arc Therapy)

N'zovuta kufotokoza mantha ndi nkhawa zomwe mumamva mukazindikira kuti inuyo kapena wokondedwa wanu ali ndi khansa. Kenako mukamva za chithandizo, mungamve mantha kwambiri mukamva za "chithandizo cha radiation." Koma sayansi ya zamankhwala ikupita patsogolo tsiku ndi tsiku. Lero tikambirana za njira imodzi yotsogola komanso yofulumira kwambiri yothandizira yomwe imangoyang'ana maselo a khansa okha komanso imachepetsa kwambiri kuwonongeka kwa maselo athanzi. Izi zimatchedwa VMAT.

Ndiye, kodi VMAT iyi ndi chiyani?

Mwachidule, VMAT ndi chidule cha 'Volumetric Modulated Arc Therapy'. Iyi ndi njira yotsogola kwambiri yogwiritsira ntchito ma radiation yomwe imagwiritsidwa ntchito kupha maselo a khansa. Kunena zoona, ndi mtundu wa External Beam Radiation Therapy (EBRT). Izi zikutanthauza kuti palibe mankhwala a radioactive omwe amalowetsedwa m'thupi lanu. Choncho palibe chifukwa chodera nkhawa kuti ma radiation amatuluka m'thupi lanu panthawi ya chithandizo kapena pambuyo pake.

Tangoganizirani, pamene mukugona pabedi, makina akuluakulu akuzungulirani pang'onopang'ono, akulunjika kuwala kwa ma radiation nthawi zonse, akulunjika malo okhawo omwe khansa ili. Ndicho chimene chimachitika ndi ukadaulo wa VMAT.

Iyi ndi njira yapamwamba kwambiri yochizira matenda a radiation, IMRT (Intensity-Modulated Radiation Therapy). Mu IMRT, m'malo mwa radiation imodzi yayikulu, radiation yaying'ono yambiri imaperekedwa ku chotupacho. Izi zimachepetsa kwambiri kuwonongeka kwa minofu yathanzi yozungulira chotupacho. Mu VMAT, njira yomweyi imachitika pamene makina akuzungulira mosalekeza, kotero chithandizocho chingachitike molondola komanso mwachangu .

Kodi chithandizo cha VMAT chimagwiritsidwa ntchito pa mitundu iti ya khansa?

Chifukwa cha kulondola kwa ukadaulo wa VMAT, ndi njira yabwino kwambiri yochizira zotupa za khansa zomwe zili ndi mawonekedwe osazolowereka kapena zomwe zili pafupi kwambiri ndi ziwalo zofunika kwambiri m'thupi lathu. Mwachitsanzo, dokotala wanu wa khansa angakulimbikitseni njira iyi pochiza khansa yomwe yakula mozungulira chiwalo.

Chithandizo cha VMAT chimagwiritsidwa ntchito kwambiri pa mitundu yotsatirayi ya khansa.

Kodi izi zimagwira ntchito bwanji? Kodi chimachitika ndi chiyani musanalandire chithandizo?

Chithandizo cha VMAT ndi njira yokonzedweratu kwambiri. Chimaphatikizapo masitepe angapo ofunikira.

1. Kukonzekera Chithandizo (Kukonzekera & Kuyerekeza)

Iyi ndi sitepe yofunika kwambiri. Gulu lanu lachipatala lidzayamba kujambula zithunzi za thupi lanu m'njira zitatu (3D). Izi nthawi zambiri zimachitika pogwiritsa ntchito CT scan, koma nthawi zina MRI kapena PET scan. Zithunzizi zidzawathandiza kudziwa komwe khansa ili, kukula kwake, mawonekedwe ake, ndi ziwalo zilizonse zathanzi zomwe zimafunika kutetezedwa ku kuwala kwa dzuwa.

Kenako pali gawo lokonzekera lotchedwa "kuyerekezera". Apa,

• Mudzaikidwa pamalo oyenera pa sofa yochizira ndipo kuwala kwa radiation kudzayikidwa kuti kugwere khansayo ndendende.
• Mungagwiritse ntchito chizindikiro cha kanthawi kochepa kapena chizindikiro chokhazikika, monga tattoo yaying'ono, pakhungu lanu kuti muzindikire komwe khansa ili.
• Mungagwiritsenso ntchito nkhungu kapena chigoba chopangidwira thupi lanu kuti mukhale pamalo omwewo popanda kusuntha panthawi ya chithandizo.

Kukonzekera kumeneku kungatenge tsiku limodzi kapena masiku angapo, chifukwa chithandizocho chiyenera kukonzedwa kuti chigwirizane ndi mawonekedwe enieni a khansa yanu, pogwiritsa ntchito kuwala kwa dzuwa kochepa ngati nsonga ya pensulo (2.5 x 5 millimeters).

2. Pa nthawi ya VMAT

Katswiri wothandiza odwala pogwiritsa ntchito ma radiation adzakuikani pabedi la chithandizo pamalo omwewo omwe munali nawo panthawi yokonzekera. Kenako adzayang'anira makina omwe amapereka ma radiation, otchedwa ``LINAC - Linear Accelerator'', kuchokera m'chipinda china. Mudzatha kulankhula naye kudzera pa maikolofoni.

Pamene chithandizo chikuyamba, makina a LINAC amazungulira pang'onopang'ono mozungulira inu. Pamene akuzungulira, kuwala kwa ma radiation amitundu yosiyanasiyana ndi mphamvu zake kumayang'ana pa chotupacho. Simudzamva kuwala kwa ma radiation kumeneku, ndipo simudzamva kupweteka kulikonse. Dokotala wothandiza odwala matenda a radiation adzayang'anira chilichonse mosamala pa kompyuta.

Ngakhale kuti chithandizo chonsecho chimatenga mphindi pafupifupi 20, kuwala kwa dzuwa kumaperekedwa kwa nthawi yochepa kwambiri, pafupifupi mphindi ziwiri. Nthawi yotsalayo imathera pamene mukuika munthu pamalo oyenera.

3. Pambuyo pa chithandizo (Pambuyo pa VMAT)

Mukamaliza chithandizo, mutha kupita kunyumba ndikuyambiranso ntchito zanu za tsiku ndi tsiku monga mwachizolowezi.

Kodi ubwino wa chithandizo cha VMAT ndi wotani?

Pali ubwino waukulu wa chithandizo cha VMAT: kulondola ndi liwiro.

Kodi pali zotsatirapo zilizonse?

Popeza chithandizo cha VMAT sichiwononga minofu yathanzi kwambiri, chiopsezo cha zotsatirapo zake chimakhala chochepa. Komabe, kuwonongeka kwina kwa maselo athanzi sikungatheke. Kaya zotsatirapo zake zimachitika kapena ayi, komanso zomwe zili, zimasiyana malinga ndi dera la thupi lomwe likuchiritsidwa .

Zomwe aliyense amakumana nazo zimasiyana. Anthu ena amamva bwino nthawi yomweyo atalandira chithandizo. Ena angatenge miyezi ingapo kuti achire bwino. Funsani dokotala zomwe mungayembekezere kutengera thanzi lanu.

Mudzapatsidwa nthawi yokumana ndi dokotala pambuyo pa chithandizo chanu. Onetsetsani kuti mwapita kukaonana ndi dokotala wanu nthawi zonse. Lankhulani ndi dokotala wanu za zizindikiro zilizonse kapena zotsatirapo zina zomwe mungakhale nazo.
