Kodi munayamba mwaganizapo kuti thupi lathu lingathe kulimbana ndi khansa lokha? Ndipotu, thupi lathu lili ndi gulu lankhondo lodabwitsa lotchedwa chitetezo chamthupi. Koma nthawi zina, chifukwa mdani wotchedwa khansa ndi woopsa kwambiri, zimakhala zovuta kuti gulu lathu lankhondo lipambane nkhondo lokha. Nthawi ngati zimenezi, tikambirana za chithandizo chomwe chimapatsa gulu lathu lankhondo maphunziro apadera, kuwonjezera mphamvu zake, ndikulibwezera kunkhondo.
Kodi chithandizo cha TIL ichi ndi chiyani?
Mwachidule, chithandizo cha TIL ndi mtundu watsopano wa chithandizo cha matenda a khansa. Chimagwira ntchito pothandiza chitetezo cha mthupi lanu kuzindikira ndikuwononga maselo a khansa.
Ngwazi ya chithandizochi ndi mtundu wapadera wa selo lotchedwa Tumor-Infiltrating Lymphocytes , lomwe mwachidule timalitcha kuti TILs .
Taganizirani izi ngati asilikali (maselo a chitetezo chamthupi) omwe akuyang'anira matupi athu. Koma asilikali awa, otchedwa TILs, ndi apadera kwambiri. Amalowa m'chotupacho, amaphunzira zofooka zake, ndikuphunzira momwe angachiwonongere bwino. Mwa kuyankhula kwina, ali ngati mphamvu zapadera zomwe zimalowa mkati mwa msasa wa adani ndikuzifufuza.
Koma vuto ndilakuti, matupi athu sangathe kupanga maselo okwanira a TIL kuti amenyane ndi khansa yakupha iyi.
Apa ndi pomwe chithandizo cha TIL chimayambira. Chimaphatikizapo kuchulukitsa maselo anu a TIL ndi mabiliyoni ambiri. Dokotala wa opaleshoni amachotsa chidutswa chaching'ono cha chotupa chanu. Kenako amachitumiza ku labu, kuwapatula asilikali a TIL, ndikuwakulitsa mpaka atafika mabiliyoni ambiri. Pomaliza, gulu lankhondo lalikulu ili, lopangidwa kuchokera ku maselo anu, limabwezeretsedwanso m'thupi lanu.
Kodi chithandizochi chimachiza mitundu yanji ya khansa?
Pofika chaka cha 2024, bungwe la US Food and Drug Administration (FDA) lavomereza chithandizo cha TIL chotchedwa lifileucel (Amtagvi®) . Ndi cha khansa ya pakhungu yomwe singathe kuchiritsidwa ndi opaleshoni yokha, kapena yomwe yafalikira ku ziwalo zina za thupi (khansa yofalikira). Chithandizochi chingakhale choyenera kwa munthu amene sayankha chithandizo chomwe nthawi zambiri chimaperekedwa ndi madokotala a khansa.
Kuphatikiza apo, madokotala akufufuza momwe chithandizo cha TIL ichi chimagwirira ntchito pa mitundu ina ya khansa, kuphatikizapo:
- Khansa ya m'mawere
- Khansa ya pachibelekero
- Khansa ya m'matumbo
- Khansa ya mutu ndi khosi
- Khansa ya m'mapapo yopanda maselo ang'onoang'ono
Kodi njira yochizira imagwira ntchito bwanji?
Izi sizinthu zomwe zimachitika nthawi imodzi. Ngakhale kuti chinthu chachikulu ndikulowetsa maselo a TIL, pali njira zingapo zomwe ziyenera kuchitidwa izi zisanachitike. Tiyeni tiwone njira yonseyi pang'onopang'ono.
| Masitepe | Kufotokozera zomwe zikuchitika |
|---|---|
| 1. Kuchotsa gawo la chotupa cha khansa | Dokotala adzachotsa kachidutswa kakang'ono ka chotupa chanu, kofanana ndi mphesa, ndikukatumiza ku labu. Mudzapatsidwa mankhwala oletsa ululu, kotero simudzamva kupweteka kulikonse panthawiyi. |
| 2. Kulekanitsa ndi kukula kwa maselo a TIL | Mu labu, maselo a TIL amachotsedwa ku chotupacho ndipo amakula kufika mabiliyoni ambiri. Izi nthawi zambiri zimatenga pafupifupi milungu isanu. Kenako, maselo amenewa amatumizidwa kuchipatala komwe mudzalandire chithandizo. |
| 3. Kupereka mankhwala a chemotherapy | Mudzaloledwa kuchipatala ndikupatsidwa mankhwala a chemotherapy kwa masiku asanu mpaka asanu ndi awiri. Izi ndi kukonzekera thupi lanu kuti maselo atsopano a TIL afike. |
| 4. Kubwezeretsanso maselo a TIL | Tsopano pakubwera gawo lofunika. Maselo a TIL omwe akukula amalowetsedwa m'thupi lanu nthawi imodzi, monga momwe amachitira ndi madzi amchere. Izi zimatenga pafupifupi maola awiri. |
| 5. Kupereka Interleukin-2 | Pomaliza, kwa masiku atatu kapena asanu, mudzapatsidwa mankhwala otchedwa interleukin-2 (IL-2). Uwu ndi mtundu wina wa chithandizo cha immunotherapy. Umagwira ntchito poyambitsa maselo atsopano a TIL ndikuwalimbikitsa kulimbana ndi khansa. |
Mudzafunika kukhala m'chipatala kwa masiku angapo mutalandira chithandizo. Panthawiyi, gulu lachipatala lidzayang'anira momwe thupi lanu limayankhira chithandizocho. Kwa milungu ingapo yotsatira, ndikofunikira kukhala pafupi ndi chipatala kuti mupeze chithandizo mwachangu ngati pali zotsatirapo zina.
Kodi ubwino ndi zoopsa za chithandizochi ndi ziti?
Kodi ubwino wake ndi wotani?
Chithandizo cha TIL ndi chithandizo chapadera kwambiri komanso champhamvu kwambiri. Chifukwa chimagwiritsa ntchito maselo anu, pali kuwonongeka kochepa kwa maselo athanzi. Chifukwa chake, chiopsezo cha zotsatirapo zake ndi chochepa.
Chofunika kwambiri n’chakuti, zotsatira za chithandizochi zimakhala zokhalitsa . Maselo a TIL omwe amabayidwa amakhala m’thupi lanu kwa zaka zambiri, akumenyana ndi maselo a khansa.
Chithandizochi chapereka chiyembekezo chatsopano kwa odwala ambiri a melanoma omwe poyamba ankaganiza kuti palibe mankhwala. Malinga ndi kafukufuku wa 2023, patatha zaka zinayi atalandira chithandizo cha TIL, anthu asanu ndi awiri mwa khumi adachiritsidwa kapena kuchiritsidwa matenda awo.
Zoopsa ndi zotsatira zake
Monga momwe zimakhalira ndi chithandizo chilichonse, pali zoopsa pa gawo lililonse la ndondomekoyi. Zotsatirapo zake zimachitika makamaka chifukwa cha mankhwala a chemotherapy ndi IL-2. Zotsatirapo zoyipa zomwe zimachitika chifukwa cha kuperekedwa kwa maselo a TIL ndizosowa kwambiri.
| Zotsatira zoyipa zofala | |
|---|---|
| Kutsegula m'mimba | Kutopa |
| Malungo ndi kuzizira | Kugunda kwa mtima kosakhazikika (arrhythmia) |
| Kuthamanga kwa magazi kotsika | Kusanza ndi kusanza |
| Kutupa pakhungu | |
Kawirikawiri, chifukwa cha chithandizo cha IL-2Vuto lalikulu, monga capillary leak syndrome, likhoza kuchitika. Koma musadandaule, dokotala wanu adzakambirana nanu momveka bwino zoopsa zonsezi musanayambe kulandira chithandizo.
Kodi zinditengera nthawi yayitali bwanji kuti ndibwererenso ku moyo wabwinobwino?
Mudzayamba kumva bwino patatha milungu iwiri mutatha kumwa mankhwala omaliza a IL-2. Popeza njira yochizira iyi imakhala ndi zinthu zambiri, monga opaleshoni ndi chemotherapy, zimatenga nthawi kuti thupi libwererenso.
Kodi muyenera kukaonana ndi dokotala liti?
Mukalandira chithandizo, ngati mukupeza zizindikiro za matenda (malungo, kupweteka kwa thupi), kapena ngati mukukumana ndi zotsatirapo zoyipa zosayembekezereka, imbani dokotala nthawi yomweyo.
Ngati mukumva kusintha kulikonse kapena kusasangalala, musazengereze kuuza dokotala wanu. Musayese kusankha ngati ndi zachilendo kapena ayi. Ndi bwino kunena nthawi yomweyo.
Ngati muli ndi khansa ya melanoma yomwe sinayankhe mankhwala ena, TIL ikhoza kukhala njira yabwino kwa inu. Ngati dokotala wanu akulangizani chithandizochi, funsani mafunso aliwonse omwe muli nawo okhudza chithandizochi. Lankhulani ndi dokotala wanu za ubwino ndi zoopsa zake. Dokotala wanu ndiye gwero lanu labwino kwambiri la chidziwitso.
Uthenga Wopita Nawo Kunyumba
- Chithandizo cha TIL ndi njira yatsopano komanso yamphamvu yochizira matenda yomwe imagwiritsa ntchito maselo anu oteteza thupi kuti amenyane ndi khansa.
- Izi zikuphatikizapo kukulitsa mabiliyoni a maselo otengedwa kuchokera ku chotupa cha khansa mu labu kenako nkuwabwezeretsanso m'thupi.
- Pakadali pano, imavomerezedwa makamaka ku khansa ya melanoma yomwe sinayankhepo ku mankhwala ena, komanso ili mu gawo lofufuza za khansa zina.
- Iyi ndi njira yovuta yokhala ndi masitepe angapo, kuphatikizapo opaleshoni, mankhwala a chemotherapy, ndi mankhwala.
- Nthawi iliyonse, kambiranani momasuka ndi dokotala wanu za ubwino, kuipa, ndi zoopsa za chithandizochi ndipo pangani zisankho zodziwa bwino.
