Kurapa kenza (chemotherapy) ndeimwe yemishonga inonyanya kutaurwa nezvayo uye inonyanya kutaurwa nezvayo. Izvi zvinosanganisira kutumira mishonga kuburikidza neropa redu kuti iuraye masero ekenza uye kuamisa kukura. Asi waizviziva here kuti kune mhando dzakasiyana dzemishonga yechemotherapy inoshanda zvakasiyana? Mishonga yeAntimetabolites ndeimwe yemhando dzakasiyana dzemishonga. Kunyangwe zita racho ringanzwika serakaoma, mashandiro aro anoshamisa. Nhasi tichataura nezvemishonga iyi yeAntimetabolites.
Ma antimetabolites aya anouraya sei masero ekenza?
Zvichitaurwa zviri nyore, mushonga uyu unonyengera masero ekenza, sekupa kiyi yenhema yakafanana neyechokwadi.
Kuti tinzwisise izvi, ngatitangei tatarisa kuti sero regomarara rinogadzira sei (rinopatsanura) masero akawanda. Kufanana nesero rega rega mumuviri wedu, masero egomarara ane chimwe chinhu chinonzi DNA. Funga nezveizvi se "bhuku remirairo" resero kana "purani." Iyi ndiyo hurongwa hwesero, uye kuti rinogadzira sei mamwe makopi aro.
Kuti ugadzire gwaro iri reDNA nemazvo, sero rinoda zvinhu zvakakosha. Kungofanana nekuvaka imba kunoda zvidhinha nesimende. Tinodaidza zvinhu izvi kuti metabolites. Izvi zvinonyanya kukosha ndeizvi:
- Mapurini: Aya ndiwo maburi akakosha eDNA neRNA.
- MaPyrimidines: Aya ndiwo maburi akakosha eDNA neRNA.
- Folic acid: Iyi imhando yevhitamini inopa simba rekuita kuti masero apatsanurwe.
Zvino, hezvino zvinoitwa nemushonga unodzivirira metabolite. Molekyuri iyi yemushonga yakagadzirwa zvakafanana nezvinhu chaizvo (metabolites) zvataurwa pamusoro apa. Saka, kana sero rekenza richiedza kugadzira DNA yaro, rinoshandisa chinhu ichi chenhema, mushonga wacho, richifunga kuti ndicho chinhu chaicho.
Fungidzira uri kubika mupunga. Unofunga kuti munyu wobva wawedzera shuga yaunoona. Chii chinoitika ipapo? Kuravira uye magadzirirwo emupunga wese zvinokanganiswa, handiti? Saizvozvowo, kana sero rekenza rikashandisa chinhu ichi chenhema, DNA plan yaro inenge isina kunaka zvachose. Neplan isiriyo, sero harigone kugadzira mamwe makopi. Pakupedzisira, sero rekenza harigone kupatsanuka zvakare rofa.
Ndeapi marudzi makuru emishonga inoderedza metabolites?
Unoyeuka zvinhu zvitatu zvakakosha zvatakambotaura nezvazvo? Mishonga iyi yakakamurwa kuita mhando nhatu huru, zvichienderana nekuti ndeipi yezvikamu zvitatu izvi yainonanga.
- Zvinorwisa ma purine: Izvi zvinomisa masero ekenza kugadzira ma purine.
- Mishonga inodzivirira kenza: Izvi zvinomisa masero egomarara kugadzira mishonga inonzi pyrimidines.
- Mishonga inodzivirira folic acid (antifolates):Izvi zvinodzivirira masero egomarara kuti asashandise folic acid kugadzira DNA.
Mushonga uyu unoshandiswa kumhando dzipi dzegomarara?
Mishonga yekudzivirira chirwere ichi inoshandiswa kurapa mhando dzakasiyana dzegomarara. Chiremba wako ndiye achasarudza kuti mushonga upi wakakunakira zvichienderana nerudzi rwegomarara raunaro, danho raro, uye kuti wakapindura sei pakurapwa kwawakamboita. Mimwe mishonga inoshandiswawo kurapa zvimwe zvirwere (zvakaita sezvirwere zve autoimmune) pamwe negomarara.
Tafura iri pazasi inoratidza mimwe yemishonga inonyanya kushandiswa yekurwisa metabolite uye mhando dzegomarara ravanorapa.
| Zita reMushonga | Mhando dzeKenza Dzinorapwa |
|---|---|
| Fluorouracil (5-FU) | Kenza dzemazamu, dzemuura, dzemudumbu, dzepancreas, uye dzeganda |
| Capecitabine (Xeloda®) | Kenza yemazamu, ura, dumbu, gumbo, uye kenza yepancreas |
| Gemcitabine (Gemzar®) | Kenza yemazamu, yemapapu (isiri diki), kenza yemazamu neyepancreas |
| Methotrexate | Leukemia, lymphoma, kenza yemazamu, yemapapu, yemusoro nemutsipa, kenza yemapfupa (Osteosarcoma) |
| Cytarabine | Mhando dzakasiyana dzeleukemia (Acute myeloid, ALL, CML) |
| Hydroxyurea | Leukemia (CML), kenza yemusoro nemutsipa |
Mushonga uyu unopihwa sei mumuviri?
Kune nzira dzakasiyana siyana dzekushandisa mishonga iyi, zvichienderana nerudzi rwemushonga uri kupiwa.
- Mutsinga (IV): Iyi ndiyo nzira inonyanya kushandiswa. Mushonga uyu unopinzwa mumuviri semushonga wesaline kuburikidza ne cannula kana chemo port inoiswa paruoko kana pachipfuva. Kurapa uku kunogona kutora maminetsi mashoma, maawa mashoma, kana kunyange mazuva mashoma.
- Sekubaiwa jekiseni: Mimwe mishonga inopihwawo sekubaiwa jekiseni muchikamu chine mafuta chiri pasi peganda.
- Mapiritsi: Mamwe mapiritsi anodzivirira metabolites anowanikwawo semapiritsi anogona kumedzwa.
- Sekirimu yemushonga weganda: Mushonga we5-FU, unoshandiswa kurapa kenza yeganda (basal cell carcinoma), unowanikwawo sekirimu yemushonga weganda.
Ndezvipi zvingakonzera migumisiro yekurapwa?
Chinhu chinowanzoonekwa nemishonga yechemotherapy ndechekuti inotarisa masero anokamuka nekukurumidza. Masero egomarara rudzi rwesero rinokamuka nekukurumidza. Asi dambudziko nderekuti, mamwe masero ane hutano mumuviri wedu anokamuka nekukurumidza. Semuenzaniso:
- Masero ebvudzi
- Masero mumuromo nemudumbu
- Masero eganda
- Masero anogadzira ropa
Mishonga inorwisa mabhakitiriya haigone kusiyanisa masero ekenza nemasero ane hutano. Nokudaro, masero aya ane hutano anogonawo kukuvara. Ndosaka migumisiro yakaipa ichiitika.
Migumisiro yakajairika ndeiyi:
- Kuneta uye kuneta
- Kudonha kwebvudzi
- Kuchinja kweganda (semuenzaniso mapundu )
- Kusvotwa nekurutsa
- Manyoka (kurwadziwa kwemudumbu)
- Kuda kudya
Asi migumisiro iyi haiitike kune wese munhu nenzira imwe chete. Zvinoenderana nemushonga waunopiwa, chiyero, nezvimwewo. Saka zvakakosha kutaura nachiremba wako nezveizvi usati watanga kurapwa. Iye zvino kune mishonga yakawanda yekudzora migumisiro yacho.
Ndezvipi zvakanakira uye njodzi dzekurapa uku?
Zvakanakira:
Chinhu chikuru chinobatsira pakurwisa kenza ndechekuti inouraya masero ekenza uye inomisa kukura kwegomarara. Izvi zvinogona kuwedzera hupenyu hwemunhu anorarama negomarara uye kuita kuti hupenyu huve nyore nekuderedza zviratidzo.
Njodzi:
Dambudziko guru nderemigumisiro yatakambotaura nezvayo. Uyewo, hazvisi zvese zvinorapa kenza zvinoshanda zvakafanana kune wese munhu. Mushonga chaiwo ungasashanda kune kenza yako. Nekufamba kwenguva, masero ekenza anogona kuramba mushonga wacho, uye mushonga wacho ungasashanda zvakanaka. Kana izvi zvikaitika, chiremba wako anogona kukurudzira mushonga wechemotherapy wakasiyana kana imwe nzira yekurapa (semuenzaniso, radiation, immunotherapy).
Kana uine pamuviri, uchiyamwisa, kana kuti uine chimwe chirwere, iva nechokwadi chekuzivisa chiremba wako usati watanga kurapwa uku.
Mharidzo Yekuenda Nayo Kumba
- Mishonga inorwisa mabhakitiriya (antimetabolites) imhando yemishonga yechemotherapy inonyengera masero ekenza kuti asapatsanuke.
- Mishonga iyi inoshanda nekudzivirira masero egomarara kuti asawane zvinhu zvinodiwa kuti agadzire DNA yavo (genetic planning).
- Izvi zvinoshandiswa kurapa mhando dzakasiyana dzegomarara, dzakadai sezamu, mapapu, uye leukemia.
- Migumisiro yakaipa yakadai sekudonha kwebvudzi uye kuda kurutsa inogona kuitika nekuti mushonga uyu unokanganisawo masero ane hutano anopatsanuka nekukurumidza.
- Kudzidza nezvemushonga kunogona kutyisa zvishoma. Asi usambotya kubvunza chiremba wako nezvemushonga wauri kupihwa, zvakanakira, zvakaipa, uye migumisiro yawo. Kuva neruzivo rwakanaka chikamu chakakosha chekurapa.
