Empini enzima yokulwa nezimila, yonke indlela yokwelapha ephumelelayo ifana nendlu yokukhanyisa ekhanyisa indlela engaphambili. I-Capecitabine, njengomuthi ovelele emkhakheni wokwelashwa kwezimila, iletha ithemba elisha ezigulini eziningi ngokusebenza kwayo okuvelele kanye nezinzuzo ezihlukile. I-Capecitabine umuthi we-chemotherapy omlomo oyisimangaliso. Isebenza njenge-ejenti eqeqeshwe kahle emzimbeni womuntu, ihlose ngqo amangqamuzana ezimila. Ngemva kokuphathwa ngomlomo, umuncwa ngokushesha ngumzimba womuntu futhi, ngochungechunge lwezindlela zokusabela ezihlakaniphile ze-enzyme chain, iguqulwa ngqo ibe yi-5-fluorouracil (5-FU), enobuthi obunamandla. Okumangazayo nakakhulu, le nqubo yokuguqulwa yenzeka kakhulu ezicutshini zezimila. I-thymidine phosphorylase (TP) eyingqayizivele egxile kakhulu ezicutshini zezimila ifana nokuvula umnyango ozinikele we-capecitabine, okwenza ikwazi ukuguqulwa ngempumelelo ibe yi-5 FU, ngaleyo ndlela ihlose ngqo ukwakheka kwe-DNA ne-RNA kwamaseli ezimila, ivimbele ngempumelelo ukwanda okukhulu nokusabalala kwamaseli ezimila, futhi inciphise umonakalo kumaseli avamile ngezinga elikhulu. Nakuba kuqinisekiswa umphumela wokulwa nomdlavuza, kunciphisa kakhulu imiphumela enobuthi kanye neyomuthi ezicutshini zomzimba ezivamile. Isebenza ezinhlotsheni eziningi zomdlavuza, ivikela impilo ngokuphelele. 1. Isikhali esinamandla ekwelapheni umdlavuza webele: Umdlavuza webele usongela kakhulu impilo yabesifazane emhlabeni jikelele. Ezigulini ezinomdlavuza webele ophindaphindayo noma osakazeke kakhulu, ikakhulukazi lezo eziye zathola ukumelana nemithi yendabuko ye-anthracyclines kanye nemithi ye-taxanes chemotherapy, i-capecitabine ngokungangabazeki iyinhlansi yethemba ebumnyameni. Imininingwane yocwaningo lwezokwelapha iyakhuthaza. I-Capecitabine ehlanganiswe neminye imithi ye-chemotherapy ingakhuphula izinga lokulawula isifo seziguli libe ngu-60% kuya ku-70%, futhi yandise ukusinda okuphakathi okungenalo ukuqhubekela phambili kube izinyanga ezingu-8 kuya kwezingu-10. Kungakhathaliseki ukuthi isetshenziswa yodwa noma ihlanganiswe nemithi efana ne-docetaxel, i-capecitabine ibonise umsebenzi oqinile wokulwa nomdlavuza, ivula izindlela ezintsha zokwelapha iziguli ezinomdlavuza webele. 2. Izinqumo Ezibalulekile Zokwelashwa Komdlavuza We-Colorectal: Emkhakheni wokwelashwa komdlavuza we-colorectal, i-capecitabine nayo idlala indima engenakuphikwa futhi ebalulekile. Ezigulini ezinomdlavuza we-colorectal osezingeni eliphezulu noma osakazekile, uhlelo lwe-XELOX olujwayelekile oluhlanganiswe ne-capecitabine ne-oxaliplatin selube olunye lwezindlela zokwelapha ezikhethwayo zomugqa wokuqala. Imininingwane yezokwelapha ikhombisa ukuthi ezigulini ezelashwa ngalolu hlelo lokwelapha oluhlanganisiwe, izinga lokubuyela emuva kwesimila lingafinyelela ku-30% kuya ku-40%, kanti isikhathi sokusinda esimaphakathi singandiswa sibe yizinyanga ezingu-20 kuya kwezingu-24. Akukhona lokho kuphela, ekwelashweni okusizayo ngemva kokuhlinzwa komdlavuza we-colorectal, i-capecitabine inganciphisa ngempumelelo ingozi yokubuyela emuva kweziguli ezisezingeni lesi-II nelesi-III, ilethe ithemba lokusinda isikhathi eside kuzo. 3. Ithemba Elisha Lokwelashwa Komdlavuza Wesisu: Ukwelashwa komdlavuza wesisu bekulokhu kungenye yezinselelo emkhakheni wezokwelapha. I-Capecitabine inikeza inketho entsha yokwelapha iziguli ezinomdlavuza wesisu osezingeni eliphezulu noma osakazekile ongakwazi ukuhlinza. Ingasetshenziswa yodwa noma ihlanganiswe nemithi efana ne-cisplatin, ithuthukisa kakhulu ikhwalithi yokuphila kweziguli futhi yandise isikhathi sazo sokusinda. Ku-chemotherapy ye-adjuvant yeziguli ezine-gastric adenocarcinoma yesigaba sesi-II nesesi-III ngemuva kokususwa okukhulu, inhlanganisela ye-capecitabine kanye ne-oxaliplatin (XELOX) regimen inikeza isiqinisekiso esinamandla sokunciphisa ingozi yokuphinda kuvele futhi kuthuthukiswe izinga lokuphulukiswa. 4. Ukuhlola nokusetshenziswa kwezinhlobo eziningi zomdlavuza: Ngokuqhubeka kocwaningo lwezokwelapha, i-capecitabine iye yavela kancane kancane ekwelapheni umdlavuza we-pancreatic kanye nezinye izimila eziqinile. Ezivivinyweni zemitholampilo zokwelapha umdlavuza we-pancreatic, uma isetshenziswa kanye ne-gemcitabine, ukuqhubeka kwesifo kwezinye iziguli kwalawulwa ngempumelelo. Ububanzi bokusetshenziswa kwe-capecitabine buyaqhubeka nokukhula, buhlinzeka iziguli eziningi ezinomdlavuza ngezinketho zokwelapha ezahlukahlukene. Ukuphathwa ngomlomo kulula futhi kuthuthukisa ikhwalithi yokuphila. I-chemotherapy yendabuko ivame ukuhambisana nokuya njalo esibhedlela kanye nokujova ngemithambo yegazi kanye nezinye izinqubo ezinzima, okuletha ukuphazamiseka okukhulu ezigulini. I-Capecitabine isishintshe ngokuphelele lesi simo ngokuphathwa ngomlomo. Iziguli azidingi ukuvakashela esibhedlela njalo. Zidinga nje ukuthatha umuthi ngesikhathi njengoba kunqunywe udokotela futhi zingaqeda kalula ukwelashwa. Lokhu akugcini nje ngokuthuthukisa kakhulu ukuthobela ukwelashwa kweziguli, kodwa futhi kuzenza zikwazi ukuthola ukwelashwa endaweni yomndeni ejwayelekile, kunciphisa ingcindezi yengqondo ebangelwa ukulaliswa esibhedlela. Kugcina ikhwalithi yokuphila kweziguli ngezinga elikhulu futhi kuzivumela ukuthi zizwe ukufudumala nesithunzi sempilo ngesikhathi senqubo yokulwa nezimila. Ithimba lochwepheshe lihlinzeka ngesivikelo esiphelele kuyo yonke inqubo yokwelashwa nge-capecitabine. Iziguli azilwi zodwa. Ithimba lochwepheshe bezokwelapha lizohlinzeka ngesivikelo esiphelele sesiguli kuyo yonke inqubo. Odokotela bazokwakha izinhlelo zokwelapha ezenzelwe wena ngokusekelwe esimweni esithile sesiguli, isimo somzimba, kanye nokubonakaliswa kwezakhi zofuzo zesimila, njll., ukuqinisekisa ukunemba komthamo kanye nenkambo yokwelashwa kwemithi. Okwamanje, abasebenzi bezokwelapha bazoqapha ngokucophelela ukusabela komzimba kwesiguli ngesikhathi senqubo yokwelashwa futhi babhekane ngokushesha nanoma yikuphi ukusabela okubi okungenzeka, njengokulungisa umthamo, ukuhlinzeka ngemithi enezimpawu, kanye nokunikeza isiqondiso esiphelele sokunakekela, ukunciphisa ukungakhululeki kwesiguli nokuqinisekisa intuthuko ebushelelezi yokwelashwa. I-Capecitabine, ngendlela yayo eqondile yokusebenza, ukusetshenziswa kwayo okubanzi ezinhlotsheni eziningi zomdlavuza, indlela elula yokuphatha ngomlomo kanye nokusekelwa kwethimba lochwepheshe bezokwelapha, isibe yinsika emkhakheni wokwelashwa kwezimila. Ilethe ithemba lokusinda ezigulini eziningi zomdlavuza. Masibheke phambili kuyo ukuthi yenze intuthuko eyengeziwe ocwaningweni lwezokwelapha lwesikhathi esizayo futhi yenze iminikelo emikhulu emzamweni omkhulu we-victo yesintu.khuluma ngamathumba. Uma wena noma othile oseduze nawe elwa nomdlavuza, kungcono ufunde nge-capecitabine. Mhlawumbe iyisihluthulelo sokuvula umnyango wempilo.
