Yini i-Porfimer: Ukusetshenziswa, Umthamo, Imiphumela Eceleni nokuningi

I-Porfimer iyimithi ekhethekile esetshenziswa ekwelashweni nge-photodynamic ukwelapha izinhlobo ezithile zomdlavuza. Iyisithako esenza ukuthi amangqamuzana omdlavuza azwele kakhulu ukukhanya, okuvumela odokotela ukuthi bawahlasele futhi bawaqede ngokwelashwa nge-laser.

Le mithi isebenza ngendlela ehlukile kunemithi yamakhemikhali yendabuko. Esikhundleni sokuhlasela amangqamuzana omdlavuza ngqo, i-porfimer iqongelela ezicutshini zomdlavuza bese icushwa ngohlobo oluthile lokukhanya kwe-laser ngesikhathi senqubo yezokwelapha.

Yini i-Porfimer?

I-Porfimer sodium iyimithi yokwelapha umdlavuza ecushwa ukukhanya eyingxenye yeqembu lezidakamizwa elibizwa ngokuthi ama-photosensitizers. Inikezwa ngomugqa we-intravenous (IV) ngqo emjondolo wakho wegazi.

Le mithi itholakala ezingxenyeni zegazi futhi yakhelwe ngokukhethekile ukuthi igxile emangqamuzaneni omdlavuza. Uma isifikile ezicutshini zomdlavuza, ihlala ingasebenzi kuze kube yilapho udokotela wakho esebenzisa ubude obuthile bokukhanya okubomvu ngesikhathi sokwelashwa.

Le nqubo eyingqayizivele yezinyathelo ezimbili ivumela ukwelashwa komdlavuza okuhloswe ngqo. Imithi ngokwayo ayilimazi amangqamuzana anempilo kuze kube yilapho kwenzeka ukucushwa kokukhanya, okwenzeka kuphela lapho udokotela wakho eqondisa khona i-laser.

Isetshenziselwani i-Porfimer?

I-Porfimer isetshenziswa ikakhulukazi ukwelapha umdlavuza we-esophageal osabalale noma ongakhishwa ngokuhlinzwa. Isetshenziswa futhi ngezinhlobo ezithile zomdlavuza wamaphaphu nezimo ezingaphambi komdlavuza ku-esophagus.

Udokotela wakho angase ancome i-porfimer lapho okunye ukwelashwa kungasebenzi noma lapho ukuhlinzwa kungenzeki. Ilusizo ikakhulukazi emdlavuzeni otholakala ezindaweni lapho ukuhlinzwa kwendabuko kungaba yingozi kakhulu.

Le mithi isetshenziswa futhi ukwelapha i-Barrett's esophagus enokungahambi kahle okukhulu. Lesi yisimo lapho ukumbozwa kwe-esophagus kushintshile futhi kungase kube nomdlavuza.

Kwezinye izimo, odokotela basebenzisa i-porfimer ngezinhlobo ezithile zomdlavuza wesikhumba noma eminye imidlavuza efinyeleleka ekwelashweni ngokukhanya. Nokho, lezi zindlela zokusebenzisa azivamile futhi zincike esimweni sakho esithile.

Isebenza Kanjani I-Porfimer?

I-Porfimer isebenza ngenqubo ebizwa ngokuthi i-photodynamic therapy, ehlanganisa imithi nokukhanya ukuze kubhujiswe amaseli omdlavuza. Ithathwa njengokwelashwa okuhloswe ngakho kunokwelashwa okunamandla okuhlelekile njenge-chemotherapy yendabuko.

Ngemva kokuthola umjovo we-IV, i-porfimer ihamba ngegazi lakho futhi iqoqane emaseleni omdlavuza emahoreni angu-24 kuya kwangu-72. Amaseli omdlavuza athambekele ekubambeni imithi isikhathi eside kunamaseli anempilo.

Ngesikhathi sokwelashwa ngokukhanya, udokotela wakho usebenzisa i-laser ekhethekile noma umthombo wokukhanya ukuze asebenzise i-porfimer. Lokhu kusebenza kudala ama-molecule e-oxygen anobuthi emaseleni omdlavuza, okubangela ukuba afe.

Ukwelashwa kulula uma kuqhathaniswa nezinye izindlela zokwelapha umdlavuza. Njengoba imithi isebenza kuphela uma ivezwa kubude obuthile bokukhanya, ayibangeli imiphumela emibi ebanzi evame ukubonwa nge-chemotherapy yendabuko.

Kufanele Ngiyithathe Kanjani I-Porfimer?

I-Porfimer ihlinzekwa njalo ochwepheshe bezempilo ngomugqa we-IV esibhedlela noma emtholampilo. Awukwazi ukuthatha le mithi ekhaya noma ngomlomo.

Ngaphambi kokwelashwa kwakho, akudingeki ukuthi uzile noma ugweme ukudla okuthile. Nokho, udokotela wakho uzokunikeza imiyalelo enemininingwane mayelana nokulungiselela iseshini yokwelapha ngokukhanya elandelayo.

Umjovo ngokwawo ngokuvamile uthatha imizuzu engaba ngu-10 kuya kwengu-15. Ngemva kokuthola i-porfimer, uzodinga ukulinda amahora angu-24 kuya kwangu-72 ngaphambi kwengxenye yokwelashwa ngokukhanya kokwelashwa kwakho.

Ngesikhathi sokulinda phakathi komjovo nokwelashwa ngokukhanya, uzodinga ukugwema izibani eziqhakazile nelanga eliqondile. Ithimba lakho lezempilo lizokunikeza imihlahlandlela ethile mayelana nokuchayeka ekukhanyeni ngalesi sikhathi.

Ngizothatha isikhathi esingakanani i-Porfimer?

Ukwelashwa nge-Porfimer ngokuvamile kuhilela umjovo owodwa olandelwa ukwelashwa okukodwa noma ngaphezulu kokukhanya. Umjikelezo wonke wokwelashwa ngokuvamile wenzeka ezinsukwini ezimbalwa kuya evikini.

Ezinye iziguli zingase zidinge ukwelashwa okuphindwayo, kodwa lokhu kuncike ekutheni umdlavuza uphendula kanjani kanye nesimo sakho sempilo esiphelele. Udokotela wakho uzoqapha inqubekela phambili yakho futhi anqume ukuthi ngabe imijikelezo eyengeziwe iyadingeka yini.

Imiphumela ye-porfimer ingahlala amasonto amaningana ngemuva kokwelashwa. Ngesikhathi esinjalo, uzodinga ukuqhubeka nokuzivikela emalini ekhanyayo naselangeni.

Udokotela wakho uzohlela ama-aphoyintimenti okuqapha njalo ukuze ahlolisise ukuthi ukwelashwa kusebenze kahle kangakanani nokuthi aqaphele noma yimaphi imiphumela emibi. Lokhu kuvakasha kubalulekile ekunqumeni ukuthi ngabe ukwelashwa okwengeziwe kuyadingeka yini.

Yiziphi Imiphumela Emibi ye-Porfimer?

Umphumela omubi obaluleke kakhulu we-porfimer ukwanda kokuzwela ekukhanyeni, okungahlala amasonto ama-4 kuya kwangu-6 ngemuva kokwelashwa. Lokhu kusho ukuthi uzodinga ukugwema amalambu aqinile nelanga ngqo ngalesi sikhathi.

Imiphumela emibi ejwayelekile abaningi abayizwayo ihlanganisa:

• Ubuhlungu besifuba noma ukungakhululeki
• Ubunzima bokugwinya
• Isicanucanu nokuhlanza
• Umkhuhlane nokubanda
• Ukukhathala
• Ukhwehlela

Lezi zimpawu zivame ukuvela ezinsukwini zokuqala ngemuva kokwelashwa futhi ngokuvamile zithuthuka ngokuhamba kwesikhathi. Ithimba lakho lezempilo lizohlinzeka ngemithi ukusiza ukuphatha le miphumela emibi.

Imiphumela emibi ebucayi kodwa engavamile ingahlanganisa ubunzima bokuphefumula, ubuhlungu obukhulu besifuba, noma izimpawu zokutheleleka. Uma uhlangabezana nanoma yiziphi zalezi zimpawu, kufanele uthinte umhlinzeki wakho wezempilo ngokushesha.

Ezinye iziguli zingase zithuthukise ukusabela kwesikhumba uma zivezwe ekukhanyeni okukhanyayo ngesikhathi esizwelayo. Yingakho ukulandela imihlahlandlela yokuchayeka ekukhanyeni kubaluleke kakhulu ekuphepheni kwakho.

Ubani Ongafanele Athole i-Porfimer?
