Kookolo wo ow'amabeere alina HER2-Positive? Kino ka twogere mu bujjuvu!

Wali owuliddeko ku kookolo w’amabeere? Mpozzi mukwano gwo oba ow’oluganda lwo abadde nabwo. Mu butuufu waliwo ebika bya kookolo w’amabeere eby’enjawulo. Leero tugenda kwogera ku emu ku zo, ey’enjawulo era esobola okusaasaana amangu katono. Oyo ye kookolo w’amabeere alina HER2-Positive (HER2-positive) . Erinnya lino bw’owulira oyinza okulowooza nti lizibu katono naye teweeraliikiriranga. Tujja kukyogerako mu ngeri ennyangu ennyo, mu ngeri gy’osobola okutegeera.

Kookolo w’amabeere alina HER2-Positive (HER2+) kye ki?

Mu ngeri ennyangu, kookolo w’amabeere alina HER2-positive (HER2+) kika kya kookolo akula amangu era asobola okusaasaana amangu ebweru w’amabeere (`invasive`) . Abasawo bwe bagamba nti olina kookolo ow’ekika kino, kitegeeza nti obutoffaali bwo obwa kookolo bulina obutoffaali obw’enjawulo obufuga okukula n’okugabanyaamu obutoffaali mu mubiri gwo – obuyitibwa ``Human Epidermal Growth Factor Receptor 2`` , oba HER2 mu bufunze. Puloteeni eno eya HER2 eringa ``akabonero'' akagamba obutoffaali okukula. Bwe kiba kisusse, obutoffaali bweyawukana mangu era nga tebufugibwa, ekivaako kookolo.

Kookolo w’amabeere ow’ekika kino atera okusaasaana (okusaasaana) okuva mu mabeere okutuuka mu bitundu by’omubiri gwo ebirala, gamba ng’ennywanto, ekibumba, amawuggwe oba n’obwongo bwo. Naye ekikulu kiri nti singa kookolo ono azuulibwa nga bukyali, nga tannasaasaana mu bitundu by’omubiri ebirala, abasawo basobola okumujjanjaba obulungi n’obujjanjabi obw’omulembe obuliwo leero. Eno y’ensonga lwaki okuzuula amangu kikulu nnyo.

Kookolo w’amabeere alina HER2-positive atera kwenkana wa?

Okusinziira ku kibiina kya American Cancer Society, abakyala abasoba mu 290,000 bagenda kuzuulibwa ne kookolo w’amabeere ayingirira (invasive ductal carcinoma ne lobular breast cancer) mu mwaka gwa 2023 gwokka. Ku bano , 15% ku 20% balina HER2-positive. Abasajja nabo basobola okufuna kookolo w’amabeere, naye kookolo w’amabeere alina HER2 tatera nnyo mu basajja.

Bubonero ki obulaga kookolo w’amabeere alina HER2?

Okufaananako n’ebika bya kookolo w’amabeere bingi, ekika kino ekya HER2-positive oluusi tekiraga bubonero obweyoleka mu kusooka. Naye obubonero bwe bulabika, bufaananako n’obwo obulabibwa mu kookolo w’amabeere owa bulijjo. Ka tulabe kiki kye bali:

• Enkyukakyuka mu sayizi, enkula oba enkula y’amabeere . Ebbeere erimu liyinza okuwulira nga linene okusinga eddala, oba enkula yaalyo eyinza okukyuka.
• Ekizimba oba ekizimba mu kitundu ky’amabeere oba enkwaso. Kino kiyinza okuba ekitono ng’entangawuuzi. Singa ekizimba kisigala nga kimaze okugenda mu nsonga, olina okweraliikirira.
• Enkyukakyuka mu ndabika oba okuwulira kw’olususu lw’amabeere oba enfuli. Olususu luyinza okukaluba, nga lufuuse ebinnya oba nga lufuukuuse, oba okuwulira nga luliko ebikuta oba nga luzimba. Oluusi olususu luyinza okuba nga lumyufu oba nga luddugavu okusinga ku lwa bulijjo.
• Okuwulira ekitundu ekikalu wansi w’olususu, ng’amayinja amabajje .
• Amazzi agalimu omusaayi oba amatangaavu agava mu nfuli.

Teebereza mukwano gwo, katumuyite "Sunita". Olunaku lumu Sunita bwe yali anaaba, yalaba enkyukakyuka entonotono mu bbeere lye. Kyawulikika ng’ekizimba ekitono. Mu kusooka, teyafaayo nnyo ku nsonga eno, ng'alowooza nti, "Kijja kumala kugenda." Naye oluvannyuma lwa wiiki ntono, kyali kikyaliwo. Oluvannyuma bwe yakiraga omusawo, yakitegeera nti kaali kabonero ka kookolo w’amabeere. N’olwekyo, bw’olaba enkyukakyuka yonna etali ya bulijjo mu mabeere go, kikulu nnyo okunoonya amagezi g’abasawo nga togibuusa maaso.

Kiki ekivaako kookolo w’amabeere alina HER2?

Kookolo w’amabeere alina HER2 ava ku nkyukakyuka mu buzaale obuyitibwa HER2. Ensengekera eno eya HER2 ekola puloteyina ya HER2 gye twayogeddeko emabegako. Puloteeni zino eza HER2 (era eziyitibwa `receptors`) mu budde obutuufu zisangibwa ku ngulu w’obutoffaali bw’amabeere bwonna.

Mu mbeera eya bulijjo, obutoffaali buno obwa HER2 bufuga okukula n’okuddaabiriza obutoffaali bw’amabeere, okukakasa nti obutoffaali obupya bwawukana mu bungi obumala okudda mu kifo ky’obutoffaali obwonooneddwa oba obufa.

Kyokka, obuzaale bwa HER2 bwe bukyusibwa, yeekolera kkopi nnyingi nnyo. Ensengekera ya HER2 bwe yeeyoleka ennyo, era ekola ekisusse ku puloteyina ya HER2. Puloteeni ya HER2 bw’eyitiridde, obutoffaali bw’amabeere bwawukana mangu ne bukula mu ngeri etafugibwa, ne bufuuka ebizimba bya kookolo.

Biki ebiyinza okuvaako kino?

Okufaananako ne kookolo w’amabeere, ensonga eziyinza okuleeta kookolo w’amabeere alina HER2 ze zimu ne kookolo w’amabeere owa bulijjo. Osobola okufuna kookolo w’amabeere oba olina ensonga zino ez’obulabe oba nedda. Kyokka ebintu bino bisobola okwongera ku bulabe bwo:

• Okubeera n'enkyukakyuka mu buzaale obusikira . Okugeza, enkyukakyuka mu buzaale BRCA1 oba BRCA2.
• Olw’okuba yali afunye kookolo w’amabeere emabegako.
• Okubeera n’embeera endala ezikwatagana n’amabeere nga `atypical ductal hyperplasia`.
• Enzirukanya y’ensonga etandika mangu okusinga eya bulijjo.
• Okuva mu nsonga kubaawo oluvannyuma lw’emyaka egya bulijjo.
• Okumira eddagala erikyusa obusimu.
• Okunywa omwenge ogusukka mu gumu olunaku.
• Nga yafunye obujjanjabi bw’amasannyalaze (radiation therapy) ku mbeera ezimu nga lymphoma (kookolo w’enkola y’amazzi).

Bizibu ki ebiva mu kookolo w’amabeere alina HER2?

HER2-Positive kookolo w’amabeere asobola okusaasaana mu bitundu by’omubiri ebirala, oba ‘metastasize’. Mu bantu nga kitundu ku bantu abalina kookolo w’amabeere ow’ekika kino, kookolo w’azuulibwa ng’amaze okusaasaana mu bitundu by’omubiri ebirala naddala obwongo. Kookolo w’amabeere asaasaanidde ku bwongo (‘metastatic breast cancer to your brain’) ayinza okutta obulamu. Eno y’ensonga lwaki okuzuula amangu n’okujjanjabibwa amangu kikulu.

Kookolo w’amabeere alina HER2 azuulibwa atya?

Abasawo okusinga bakozesa enkola y’okukebera amabeere okuzuula kookolo yenna ow’amabeere. Kino kizingiramu okuggya akatundu akatono ak’omubiri okuva mu kitundu ky’amabeere ekiteeberezebwa n’akakebera mu microscope.

Singa okukebera amabeere kukakasa nti waliwo kookolo, omusawo omukugu mu by’endwadde (omusawo mukugu mu kuzuula endwadde) ajja kukola okukebera okw’enjawulo okulaba oba obutoffaali bw’ebitundu by’amabeere bulimu puloteyina ya HER2. Waliwo ebika bibiri ebikulu eby’okukebera ku kino:

1. Immunohistochemistry (IHC): Okukebera kuno kusobozesa abakugu mu by’endwadde okunoonya puloteyina ya HER2 mu butoffaali bwa kookolo w’amabeere. Okukebera kuno kukozesa langi ey’enjawulo (immunostaining) okukebera omutindo gwa puloteyina ya HER2 mu butoffaali bwa kookolo.

2. Fluorescence in situ hybridization (FISH): Okugezesebwa kuno okwa FISH oluusi kukozesebwa okukakasa ebyava mu kukebera kwa IHC. Okukebera kuno kusobola okuzuula oba waliwo kkopi ez’enjawulo ez’obuzaale bwa HER2.

Oluvannyuma lw’okukeberebwa kuno, abasawo bongera okusengeka kookolo ono. Bakozesa `enkola y'okuteeba`. Kino kitunuulira engeri puloteyina ya HER2 gy’eri waggulu mu sampuli y’ebitundu by’amabeere, awamu n’obutoffaali bwa kookolo bumeka obuliwo. Lowooza ku nsonga eno:

• Singa okukebera kulaga nti omutindo gwa puloteyina ya HER2 mutono, gujja kuweebwa obubonero nga 0 oba 1+ . Olwo omusawo w'endwadde ajja kugamba nti HER2 negative .
• Singa wabaawo obutoffaali bwa kookolo ate nga protein level ya kigero, osobola okufuna score ya 2+ . Olwo omusawo w’endwadde naye ajja kukakasa okukebera kwa `FISH` okwayogeddwako emabegako.
• Singa wabaawo obutoffaali bwa kookolo bungi ate nga ne protein level eri waggulu nnyo, ofuna score ya 3+ . Wano omusawo w'endwadde w'agamba nti HER2 positive .

Enkola eno ey’okuweebwa obubonero y’esalawo ddala oba oli HER2-positive oba HER2-negative.

Bujjanjabi ki obuweebwa kookolo w’amabeere alina HER2?

Olw’okuba kino kika kya kookolo w’amabeere `invasive`, enkola z’obujjanjabi zisalibwawo ensonga nnyingi, gamba ng’omutendera gwa kookolo n’embeera ya HER2. Enzijanjaba zino wammanga zisobola okukozesebwa:

• Obujjanjabi obugendereddwamu:Eno y’obujjanjabi obusinga okwetongodde ku kookolo alina HER2. Kizingiramu okuwa eddagala erigenderera puloteyina ya HER2 ne litta obutoffaali bwa kookolo. Waliwo ebika by’obujjanjabi ebikulu ebiwerako wansi wa kino:
• Enzijanjaba y’obutoffaali obuziyiza endwadde (monoclonal antibody therapy): Zino zeekwata ku puloteyina ya HER2 ne zikomya obutoffaali bwa kookolo okukula.
• Tyrosine kinase inhibitor therapy: Eddagala lino liyingira mu butoffaali bwa kookolo ne liziyiza amakubo agalaga obubonero agayamba obutoffaali okukula.
• Antibody-drug conjugates (ADCs): Eno nkola ya mulembe nnyo. Mu kino, eddagala eriweweeza ku kookolo liteekebwa ku kiziyiza ekinoonya obutoffaali bwa kookolo. Olwo ekirungo kino kigenda butereevu mu butoffaali bwa kookolo ne kifulumya eddagala, ne kikendeeza ku kwonoona obutoffaali obulamu.
• Chemotherapy: Chemotherapy eweebwa nga tebannalongoosebwa okukendeeza ku kizimba (neoadjuvant therapy) oba okutta obutoffaali bwa kookolo bwonna obusigaddewo oluvannyuma lw’okulongoosebwa (adjuvant therapy). Oluusi eddagala eriweweeza ku bulwadde buweebwa wamu n’obujjanjabi obugendereddwamu.

Ng’oggyeeko kino, okusinziira ku mutendera gwa kookolo, ebintu nga `okulongoosa`, `obujjanjabi obw’amasannyalaze`, oba `obujjanjabi bw’obusimu` nabyo bisobola okukolebwa.

Biki ebiva mu bujjanjabi obwo?

Ebizibu ebivaamu bisobola okwawukana okusinziira ku bujjanjabi. Bw’oba ​​ofuna obujjanjabi, yogerako n’omusawo wo ku ngeri obujjanjabi gye bunaakukwatamu n’engeri gye bunaakwata ku bulamu bwo obwa bulijjo. Ate era, buuza omusawo wo ku bujjanjabi obw’okukkakkanya obulumi . Palliative care ye mpeereza ekuyamba okuddukanya obubonero bwa kookolo n’ebizibu ebiva mu bujjanjabi n’okukufuula ow’obutebenkevu nga bwe kisoboka ng’ojjanjabibwa. Si kya bantu bokka abatasobola kuwonya kookolo, wabula kisobola okuyamba omuntu yenna agenda mu bujjanjabi.

Obujjanjabi buno busobola okuwonya ddala kookolo w’amabeere alina HER2?

Abasawo bwe bagamba nti "bawonya" kookolo, osanga bategeeza nti kookolo yateekebwa mu kusonyiyibwa okumala emyaka ng'ajjanjabwa. Okusonyiyibwa kitegeeza nti tolina bubonero bwa kookolo era tewali kookolo asobola kusangibwa mu kukebera. Omuntu azuuliddwa nga alina kookolo w'amabeere alina HER2, n'ajjanjabwa, n'awangaala emyaka etaano atwalibwa nga "awonye."

Okusinziira ku kitongole kya US National Cancer Institute (NCI), abantu abasoba mu 90% abazuuliddwa nga balina kookolo w’amabeere alina HER2 bakyali balamu oluvannyuma lw’emyaka etaano. Bayinza okutwalibwa ng’abawonye kookolo waabwe. Wabula kookolo alina HER2 asobola okuddamu n’asaasaana mu bitundu by’omubiri ebirala. N’olwekyo, kikulu okugenda mu maaso n’okukeberebwa abasawo.

Kiki ekiwangaala ku kookolo w’amabeere alina HER2?

Emikisa gy’okuwona kookolo w’amabeere alina HER2 nagyo gyawukana okusinziira ku oba kookolo alina obusimu obukwata obusimu (HR+) oba obusimu obukwata obusimu (HR-) . .

Kookolo w’amabeere alina HER2 asobola okuziyizibwa?

Okusinga si bwe kiri. Wadde waliwo by’oyinza okukola okukendeeza ku bulabe bw’okufuna kookolo w’amabeere, kookolo w’amabeere alina HER2 ava ku nkyukakyuka mu ggiini ya HER2 ereetera obutoffaali bwa kookolo okukola. Abanoonyereza bakyanoonyereza lwaki kino kibaawo, kale tebannaba kwogera kituufu ekiyinza okukolebwa okuziyiza kookolo alina HER2.

Wabula osobola okukola ebintu bino okukendeeza ku bulabe bw’okufuna kookolo w’amabeere okutwaliza awamu:

• Faayo ku bulamu bw’amabeere go. Weekebejje amabeere buli kiseera, era okebere amabeere ku myaka n’obudde omusawo bw’akulagidde. Weetegereze enkyukakyuka yonna mu mabeere go. Mu ngeri eno, kookolo asobola okuzuulibwa nga bukyali n’ajjanjabibwa mu ngeri ennyangu.
• Kuuma omugejjo omulungi. Buno bulina okuba obuzito obukunyumira. Saba omusawo akuwe amagezi ku ngeri y’okukuuma omugejjo omulungi.
• Lya emmere ennungi. Okunoonyereza okumu kulaga nti emmere erimu enva endiirwa, ebibala, amata agalimu ekirungo kya calcium, ne puloteyina ezitaliimu mafuta esobola okukendeeza ku bulabe bwa kookolo w’amabeere. Era kirungi okussa ekkomo ku nnyama emmyufu n’ennyama erongooseddwa.
• Beera mujjumbize. Okunoonyereza kulaga nti okukola emirimu gy’omubiri buli kiseera kikendeeza ku bulabe bw’okufuna kookolo w’amabeere. Ne bw’omala eddakiika 30 zokka olunaku kirungi.
• Weewale okunywa omwenge. Okunoonyereza kulaga akakwate akaliwo wakati wa kookolo w’amabeere n’omwenge. Ekibiina ekigatta abasawo mu Amerika kigamba nti abakyala balina ekkomo ku mwenge gwe banywa ku mwenge gumu buli lunaku.

Nze nneerabirira ntya?

Okubeera ne kookolo w’amabeere kitegeeza okubeera n’obubonero bwa kookolo, obujjanjabi, n’ebizibu ebiva mu bujjanjabi. Era, oluusi, oyinza okuba ng’olina okubeera ng’olina obutali bukakafu ku biseera eby’omu maaso. Oluusi oyinza okuwulira ng’oyitiriddeko era ng’onyiize. Bw’oba ​​owulira bw’otyo, lowooza ku magezi gano agakwata ku kwerabirira:

• Funa ekiwummulo ekimala.Kookolo w’amabeere n’okumujjanjaba bikooya nnyo. Jjukira okuwummulako buli lw’owulira ng’oyagala, so si ng’olina obudde bwokka.
• Lya bulungi. Obujjanjabi buyinza okukendeeza ku njagala y’okulya, naye okulya emmere erimu ebibala, enva endiirwa, ebirungo ebizimba omubiri, n’emmere ey’empeke ennungi kijja kukuyamba okusigala ng’oli mugumu ng’ojjanjabibwa.
• Fulumya situleesi yo. Kookolo y’asinga okuleeta situleesi. Dduyiro asobola okuyamba mu kino. Okutambula buli kiseera n’okwetaba mu pulogulaamu za dduyiro nga yoga kirungi.
• Funa obuwagizi. Oli muntu awona kookolo w’amabeere era ekyo kitandikira ku lunaku lwe bakuzuulibwa. Buuza omusawo wo ku nteekateeka z'okuwona kookolo . Bino bisobola okukuyamba okuvvuunuka ebizibu ebiri mu kubeera ne kookolo w’amabeere. Okwogera n’ab’omu maka go n’emikwano gyo nakyo ngeri nnungi ey’okweyimirizaawo.

Ddi lwe nnina okulaba omusawo?

Ojja kwetaaga okulaba omusawo buli kiseera ng’ojjanjabibwa. Wabula bw’olaba enkyukakyuka empya mu mabeere go oba omubiri gwo eziyinza okuba obubonero obulaga nti kookolo wo alina HER2 asaasaana, tegeeza omusawo wo amangu ago. Okugeza kookolo w’amabeere bw’aba asaasaanidde mu mawuggwe, oyinza okufuna obubonero ng’okulumwa mu kifuba, okukwatibwa endwadde mu kifuba enfunda eziwera, okukaluubirirwa okussa oba okusesema omusaayi.

Ddi lwe nnina okugenda mu kisenge ky’abalwadde ab’amangu?

Singa omubiri gwo gukwata obujjanjabi bwa kookolo bubi okusinga bwe wali osuubira, olina okugenda mu kisenge eky’amangu. Okugeza bw’oba ​​okendedde nnyo amazzi olw’okusesema okutambula, genda mu ddwaaliro mu bwangu.

Bibuuzo ki bye nnina okubuuza omusawo wange?

Singa okukeberebwa kwo kulaga nti olina kookolo w’amabeere alina HER2, oyinza okwagala okubuuza omusawo ebibuuzo nga:

• Ddala HER2 status yange eri etya ? (i.e. obubonero bwange obwa IHC/FISH bwe buliwa?)
• Embeera yange ey'okukwata obusimu eri etya ? (HR+ oba HR-?)
• Embeera zino eza HER2 ne hormone receptor zikwata zitya ku kuteebereza kwange (i.e., okuteebereza n’enkola y’obulwadde mu biseera eby’omu maaso)?
• Bujjanjabi ki bw’onteesa? Lwaaki?
• Nsaanidde okulowooza ku ky’okwetaba mu kugezesebwa okw’obujjanjabi okujjanjaba kookolo w’amabeere alina HER2?

Okumenyawo mu kujjanjaba kookolo tekutera kubaawo. Eno y’ensonga lwaki abanoonyereza ku kookolo baali basanyufu nnyo okunoonyereza bwe kwalaga nti enkyukakyuka mu ggiini ya HER2 zireetera obutoffaali okwawukana amangu okusinga ku bulijjo. Baakizuula mangu akakwate akaliwo wakati w’enkyukakyuka mu buzaale bwa HER2 n’ebika ebimu ebya kookolo w’amabeere akula amangu. Okuva awo, baakola obujjanjabi obuyinza okujjanjaba obulungi kookolo w’amabeere alina HER2-positive mu kiseera ekisookerwako. Kati abanoonyereza essira balitadde ku kunoonya obujjanjabi obulungi obuyinza okukendeeza oba okukomya okusaasaana kwa kookolo. Okugezesebwa mu malwaliro kwe kubaawo ebizuuliddwa bino ebipya. Bw’oba ​​olina kookolo w’amabeere agenda mu bitundu ebirala (‘metastatic’) HER2-positive, yogerako n’omusawo wo ku ky’okwetaba mu kugezesebwa okw’obujjanjabi. Basobola okukuyamba.

N’ekisembayo, obubaka obutwala awaka

Kookolo w’amabeere alina HER2 kika kya kookolo wa maanyi era asaasaana mangu. Wabula olw’okuzuula obulungi era nga bukyali n’engeri z’obujjanjabi ez’omulembe, kati kisoboka okufuga obulungi n’okuwonya embeera eno.

• Bulijjo faayo ku mubiri gwo naddala amabeere. Bw’olaba enkyukakyuka yonna etali ya bulijjo, tozibuusa maaso era funa amagezi mu bwangu omusawo.
• Goberera ddala okukebera n’obujjanjabi omusawo bw’akugamba. Totya kwogera na musawo wo ku bibuuzo byonna oba ebikweraliikiriza by’oyinza okuba nabyo.
• Kikulu nnyo okusigala nga oli positive. Toli wekka. Waliwo ab’omu maka, emikwano, abasawo, n’ababuulirira abantu okukuyamba.

Tusuubira nti amawulire gano ga mugaso gy’oli. Sigala nga oli mulamu bulungi!
