Ingabe udokotela wakho wake wakhuluma ngokuhlolwa okubizwa ngokuthi 'Ama-Tumor Markers'? Noma wake wezwa leli gama ndawana thize? Kungenzeka ukuthi wake wezwa la magama amabili lapho ekhuluma ngomdlavuza. Uma uzwa leli gama, ungase uzizwe wesaba kancane, futhi umbuzo omkhulu ungase ufike engqondweni yakho. Kodwa empeleni lokhu akuyona into okufanele uyesabe. Namuhla, sizokhuluma ngalokhu kalula, ngokucacile, nangendlela ongayiqonda. Ngoba lokhu kuyinto ebaluleke kakhulu kubantu abaningi abalwa nomdlavuza kanye nemindeni yabo.
Kulungile, pho ziyini lezi zimpawu zomdlavuza?
Kalula nje, uphawu lwesimila yinoma iyiphi into emzimbeni wakho esinika ulwazi noma inkomba mayelana nomdlavuza. Ngokuvamile, lawa ngamaprotheni akhiqizwa amangqamuzana omdlavuza. Kodwa ngezinye izikhathi, ngisho namangqamuzana avamile, angewona umdlavuza angakhiqiza lawa ma-marker ngenxa yomdlavuza. Lawa ngezinye izikhathi abizwa ngokuthi ama-marker omdlavuza, noma ama-biomarker.
Cabanga ngalokhu. Njengoba nje amaphoyisa efuna ubufakazi endaweni yobugebengu, lapho odokotela besola umdlavuza, basebenzisa lolu hlobo "lobufakazi" emizimbeni yethu ukuthola ukuthi bukhona ngempela nokuthi luhlobo luni.
Lokhu akuzona nje amaprotheni. Ngezinye izikhathi ngisho nezinguquko ku-DNA yethu (ukuguqulwa kwezakhi zofuzo) zingasebenza njengezimpawu zomdlavuza. Ngakho-ke lesi yisihloko esibanzi kakhulu.
Yini esingayifunda kulezi zivivinyo?
Ama-tumor markers awawona ukuhlolwa okusetshenziswa kuphela. Udokotela uzowahlanganisa nezinye izivivinyo (isibonelo, ama-CT scan, ama-MRI scan, kanye nokuhlolwa kwe-biopsy) ukuze afinyelele esiphethweni. Lezi zivivinyo zingasitshela izinto eziningi ezibalulekile.
- Thola ulwazi ngomdlavuza: Amazinga aphezulu ezimpawu ezithile zomdlavuza angasikisela ukuba khona kohlobo oluthile lomdlavuza emzimbeni. Kodwa-ke, lokhu kukodwa akuqinisekisi ukuba khona komdlavuza.
- Kuyasiza ekuhleleni ukwelashwa: Ulwazi oluvela kulezi zimpawu lusiza ekukhetheni indlela yokwelapha efaneleka kakhulu nephumelelayo kuye ngohlobo lomdlavuza onawo.
- Bheka ukuthi ukwelashwa kwakho kwamanje kuyasebenza yini: Cabanga ukuthi welashwa umdlavuza. Ngemva kwesikhashana, udokotela wakho uzophinde ahlole izimpawu zakho zomdlavuza. Uma amazinga alezo zimpawu ehlile, kusho ukuthi ukwelashwa kuyasebenza futhi amaseli omdlavuza ayabhujiswa.
- Thola umbono wokuthi kungenzeka yini ukululama: Ngokusekelwe emazingeni ezimpawu ezithile, odokotela bangathola umbono wokuthi kungenzeka yini ukululama kulesi sifo.
- Qaphela ingozi yokuphinda umdlavuza:Ngemva kokuba umdlavuza usuphulukisiwe ngokuphelele ngemva kokwelashwa, lokhu kuhlolwa kwenziwa ngezikhathi ezithile. Uma amazinga alezi zimpawu enyuka futhi, kungaba yisixwayiso sokuqala sengozi yokuphinda umdlavuza.
Ezinye izimpawu zomdlavuza ziqondene ngqo nohlobo olulodwa lomdlavuza, kanti ezinye zinganikeza ulwazi mayelana nezinhlobo eziningana zomdlavuza.
Zikuphi lezi zimpawu zomdlavuza emzimbeni wethu?
Kunezinhlobo ezimbili eziyinhloko zezimpawu zomdlavuza, kuye ngokuthi zitholakala kuphi.
1. Ama-Tumor Markers Ajikelezayo: Lawa atholakala oketshezini lomzimba wethu. Isibonelo:
- Igazi
- Umchamo
- Isihlalo
- Umkantsha
- Amathe
Isampula yegazi ngokuvamile ingathathwa engalweni yakho. Uma kuyisampula yomchamo, amathe, noma indle, uzonikezwa imiyalelo yokuthi ungayithatha kanjani. Ukuze uthole isampula yomnkantsha, kuzodingeka wenze ukuhlinzwa okuncane okubizwa ngokuthi "i-Bone Marrow Biopsy".
2. Ama-Tumor Tissue Markers: Lawa atholakala ngaphakathi kwesimila.
- Ukuze ahlole lokhu, udokotela kumele athathe ingxenye encane yomdlavuza (i-biopsy) ayithumele elabhorethri, lapho kuhlaziywa khona lezi zimpawu.
Izinhlobo eziningana zezimpawu zomdlavuza ezisetshenziswa kakhulu
Kunezinhlobo eziningi zezimpawu zomdlavuza ezisetshenziswa ezinhlotsheni eziningi zomdlavuza. Ithebula elingezansi linikeza incazelo elula yezinye zezimpawu ezivame ukusetshenziswa.
| Igama Lomaka | Izinhlobo zomdlavuza ezihlolwayo | Isampula ezohlolwa |
|---|---|---|
| I-AFP (i-Alpha-fetoprotein) | Ukuhlola umdlavuza wesibindi, umdlavuza wamasende, kanye nezinye izimila zamangqamuzana egciwane kanye nokukala impumelelo yokwelashwa. | Isampula yegazi |
| I-BRCA1 ne- BRCA2Ukuguqulwa kwezakhi zofuzo | Ukuhlola ingozi, ukuxilongwa, kanye nokuhlela ukwelashwa komdlavuza webele kanye nomdlavuza wesibeletho. | Isampula yegazi, amathe, noma izicubu zomdlavuza |
| I-CA 19-9 | Ukulinganisa impumelelo yokwelashwa komdlavuza we-pancreas, i-gallbladder, i-bile duct kanye nesisu. | Isampula yegazi |
| I-CEA (i-Carcinoembryonic antigen) | Ukuthola ukuthi ukwelashwa komdlavuza wamathumbu amakhulu kuphumelele yini, ukuthi umdlavuza ususakazeke yini, noma ukuthi usubuyile yini. | Isampula yegazi |
| I-PSA (i-antigen ethize ye-prostate) | Ukuze kutholakale umdlavuza wendlala yabesilisa, linganisa impumelelo yokwelashwa, bese ubona ukuthi umdlavuza ubuyile yini. | Isampula yegazi |
| I-Thyroglobulin | Ngemva kokwelashwa komdlavuza we-thyroid, ukuhlola ukuthi ukwelashwa kuphumelele kangakanani, noma ukuthi umdlavuza usubuyile yini. | Isampula yegazi |
Ungawuqonda kanjani umbiko wokuhlolwa?
Lona umbuzo omkhulu abantu abaningi abanawo. Kuyaqondakala ukwesaba, "Nginezimpawu eziningi kakhulu embikweni wami, kwenzekani manje?" Ake sixoxe ngakho ngokucacile.
Kusho ukuthini uma izimpawu zomdlavuza ziphakanyisiwe?
Amazinga aphezulu ezimpawu zesimila abonisa ukuba khona komdlavuza. Noma, umdlavuza okhona ungase ukhule noma usakazekele kwezinye izindawo (owakhiwe ngama-metastasized).
Kodwa, into ebaluleke kakhulu ukuthi ngenxa yokuthi izimpawu zesimila ziphakeme, akusho ukuthi unomdlavuza ngokuphelele. Lokhu akusikho ukuxilongwa ngokwakho.
Udokotela wakho uzofinyelela esiphethweni ngokubuka lo mbiko, izimpawu zakho, kanye nayo yonke eminye imiphumela yokuhlolwa ndawonye. Ngakho-ke ungesabi ngokubheka izinombolo ezisembikweni. Qiniseka ukuthi ukhuluma nodokotela wakho ngakho.
Kusho ukuthini uma izimpawu zomdlavuza zincipha?
Lokhu ngokuvamile kuyizindaba ezinhle. Ukwehla kwamazinga okuphawula isimila ngesikhathi sokwelashwa kusho ukuthi ukwelashwa kwakho kuyasebenza nokuthi amangqamuzana omdlavuza ayalawulwa. Kodwa ngezinye izikhathi la mazinga angashintshashintsha ngesikhathi sokwelashwa. Yingakho udokotela wakho ezoqapha la mazinga ngokuhamba kwesikhathi, kunokuthembela ekuhlolweni okukodwa.
Ingabe izimpawu zomdlavuza zingaphakanyiswa ngisho noma kungekho umdlavuza?
Yebo, kungakwenza lokho. Lokhu kuyinto abantu abaningi abangayazi, kodwa kubalulekile ukuyazi. Amazinga omaka wesimila angakhushulwa ngenxa yezimo eziningi zempilo ezivamile, ezingezona ezomdlavuza. Yingakho sithi lokhu kuhlolwa kukodwa akusetshenziselwa ukuqinisekisa umdlavuza.
Ngezansi kunezinye izimo ezinjalo ezingezona ezomdlavuza.
| Isimo | Amamaki Angaba Khona Athintekile |
|---|---|
| I-anemia | Amazinga ahlukene omaka angathinteka. |
| Isifo se-thyroid | Amamaki afana ne-CEA angathinteka. |
| Ama-cyst esibeletho | I-CA-125 (uphawu lomdlavuza wesibeletho) ingase ikhuphuke. |
| Isifo sezinso | Amamaki amaningi angakhuphuka ngezinga ngoba awasuswa kahle emzimbeni. |
| Izifo zesibindi (isib. i-Hepatitis) | Amamaki afana ne-AFP kanye ne-CEA anganda. |
| Ukukhulelwa | Ezinye izimpawu, njenge-AFP, ziyanda ngokwemvelo. |
Ingabe zonke izinhlobo zomdlavuza zingatholakala ngokusebenzisa le ndlela?
Cha. Ngokwaziwa, azikho izimpawu zesimila eziqondene nazo zonke izinhlobo zomdlavuza. Ezimweni ezinjalo, udokotela uthembele ngokuphelele kwezinye izindlela ezifana ne-'CT' scans, 'MRI' scans, 'PET' scans kanye ne-biopsies ukuze kutholakale ukuxilongwa nokuqapha ukwelashwa.
Umlayezo Wokuya Nawe Ekhaya
- Izimpawu ze-tumor ziyizimpawu emzimbeni wethu ezinikeza ulwazi kanye nezinkomba mayelana nomdlavuza.
- Akunakwenzeka ukuthola ukuthi umdlavuza ukhona yini ngokusekelwe kulolu vivinyo kuphela. Ezinye izivivinyo ziyadingeka ngempela kulokho.
- Amazinga aphezulu ophawu lwesimila angabangelwa ezinye izimo zempilo ezingezona ezomdlavuza (isib. isifo sezinso, isifo sesibindi).
- Ukwehla kwala mazinga ngesikhathi sokwelashwa kungabonisa ukuthi ukwelashwa kuphumelele. Ngokufanayo, ukwanda kwamazinga ngemva kokwelashwa kungabonisa ukuphinda kwalesi sifo.
- Uma unemibuzo, ukungabaza, noma ukukhathazeka ngemiphumela yakho yokuhlolwa, into engcono kakhulu futhi okuwukuphela kwayo ongayenza ukukhuluma ngokukhululekile nodokotela wakho ngakho. Ungenzi izinqumo ngokusekelwe olwazini olutholakala ku-inthanethi.
