Kookolo wo ow'amabeere HER2-Negative? Ka twogere ku nsonga eno mu ngeri ennyangu! (HER2-Kkookolo w’amabeere atali mulungi)

Nkimanyi nti kizibu okuteeka mu bigambo by’owulira ng’omusawo akugamba nti olina kookolo w’amabeere. Kya bulijjo okuba n’ebibuuzo bingi n’okutya ebijja mu birowoozo byo. Naye ekimu ku bintu ebikulu ebiyinza okukuyamba okuyita mu lugendo luno oluzibu kwe kutegeera obutonde bwennyini obwa kookolo wo. Okumanya omutendera gwa kookolo, ekika kye, obunene bwe, n’ebimu ku puloteyina mu butoffaali bwo obwa kookolo kikulu nnyo mu kusalawo ku bujjanjabi.

Mu ngeri ennyangu, HER2-Negative kye ki?

Kino katukitegeere bwe tuti. Obutoffaali obuli mu mubiri gwaffe bulinga obuyumba obutonotono. Ennyumba zino zirina ‘antenna’ ez’enjawulo ezifuna obubaka okuva ebweru. Mu busawo, bino tubiyita ebikwata. Okuva mu antenna zino obutoffaali mwe bufuna obubaka nga ‘okukula’ ne ‘okugabanya’.

HER2 (Human Epidermal Growth Factor Receptor 2) y’emu ku antenna ez’enjawulo ezo. HER2 eyamba okufuga okukula kw’obutoffaali obulamu. Wabula obutoffaali bwa kookolo oluusi bukola ekisusse ku antenna eno eya HER2, okusinga nnyo eya bulijjo. Olwo kookolo n’afuna obubaka obutasalako obumugamba nti ‘akule’, era kookolo n’atandika okusaasaana amangu ddala. Embeera eno tugiyita HER2-Positive .

Kale, singa omusawo wo agamba nti kookolo wo ow’amabeere HER2-negative , ekyo kitegeeza nti obutoffaali bwo obwa kookolo tebulina antenna eno ey’enjawulo eya HER2. Mu ngeri ennyangu, kookolo wo talina nsonga nkulu emuleetera okukula amangu.

Omanyi otya ddala embeera ya HER2 eya kookolo wo?

Obubonero bwa kookolo bombi HER2-negative ne HER2-positive bufaanagana. Omusawo wo tasobola kukubuulira kika ki ky’olina ng’akukebera. Ajja kwetaaga okutwala akatono ku kizimba kyo (biopsy) n’akikebere. Okukebera kuno kujja kuzuula ddala obungi bwa puloteyina ya HER2 eri mu butoffaali bwa kookolo.

Tulina okutunuulira ebisinga ku HER2 yokka!

HER2 si ye nsonga yokka ekosa okukula kwa kookolo. Waliwo ebika ebirala bibiri eby’ebikwata ( hormone receptors - HR) mu mubiri gwaffe ebikwatagana n’obusimu.

• Ebintu Ebikwata Estrogen (ER) .
• Ebikozesebwa mu kukola eddagala lya progesterone (PR) .

Singa ebirungo bino biba ku butoffaali bwa kookolo, obusimu obuyitibwa estrogen ne progesterone busobola okuyamba kookolo okukula. Abasawo boogera ku bikozesebwa bino byonna nga bali wamu. Kino kitegeeza nti kookolo wo alina HER2-negative asobola okwongera okugabanyizibwamu ebika bibiri:

1. HR-Positive / HER2-Negative: Kino kitegeeza nti kookolo takwatibwa HER2, wabula akwata obusimu. Kino kye kika kya kookolo w’amabeere ekisinga okubeerawo .

2. HR-Negative / HER2-Negative: Kino kitegeeza nti kookolo takwatibwako wadde HER2 oba obusimu. Olw’okuba ebitundu bino byonna ebisatu (HER2, ER, PR) tebiriiwo, ekika kino era kiyitibwa Triple Negative .

Okumanya ensonga zino zonna kijja kukuyamba ggwe n’omusawo wo okufuna ekifaananyi ekitegeerekeka obulungi ku nneeyisa y’ebiramu eya kookolo wo, ekijja okukuyamba okulonda obujjanjabi obusinga okukutuukirawo era obukola obulungi.

Bujjanjabi ki obwa kookolo alina HER2-negative?

Olw’okuba kookolo wo HER2-negative, tojja kuweebwa bujjanjabi obugendereddwamu, obugenderera puloteyina ya HER2. Ekyo kiri bwe kityo kubanga eddagala lyetaaga okuba ne antenna ya HER2 ku butoffaali bwa kookolo okukola. Wabula obujjanjabi obulala bujja kulondebwa okusinziira ku mutendera gwa kookolo wo n’okumanya oba alina obusimu.

• Okulongoosa n’okukozesa obusannyalazo: Singa kookolo azuulibwa nga bukyali, okulongoosa asobola okumuggyawo ddala. Obujjanjabi obw’amasannyalaze era buyinza okulagirwa nga tonnalongoosebwa oba oluvannyuma lw’okulongoosebwa.

• Endocrine/ Hormone therapy: Obujjanjabi buno bukulu nnyo singa kookolo wo aba HR-Positive/HER2-Negative. Kikola nga kikendeeza ku busimu nga estrogen mu mubiri. Obusimu bwe buba buweddewo, obutoffaali bwa kookolo bufiirwa obubaka obw’okukula, era kookolo ayinza okukendeera oba okulekera awo okukula.

• Chemotherapy: Chemotherapy oluusi esobola okuweebwa nga egattibwa wamu n’obujjanjabi bwa hormone ku kookolo wa HR-positive / HER2-negative. Kino kisinziira ku bintu ng’omutendera n’ekigero kya kookolo, emyaka gyo, n’obulamu bwo okutwalira awamu. Oluusi ebizibu ebiva mu kujjanjaba eddagala biyinza okusinga emigaso, n’olwekyo kikulu okwogera n’omusawo wo ku bisinga okukukwatako.

• Obujjanjabi bw’abaserikale b’omubiri: Singa kookolo wo aba triple negative era nga ya mulembe, era ng’alina puloteyina endala eyitibwa PD-L1, obujjanjabi buno buyinza okuba obw’okulondako. Kikola nga kisitula abaserikale b’omubiri gwo okulwanyisa kookolo.

Entunula n’okuteebereza

Ekisinga obukulu ku kookolo w’amabeere kwe kumuzuula nga tannasaasaana mu bitundu by’omubiri ebirala. Singa kookolo wo atalina HER2 abeera mu kitundu ku mabeere, omuwendo gw’okuwangaala okw’emyaka 5 guli waggulu nnyo. Kino kituufu naddala singa kookolo wo aba alina HR-positive.

Kookolo ow’emirundi esatu (triple-negative cancers) alina okusoomoozebwa okutono okujjanjaba kubanga taddamu ku bujjanjabi bwa busimu oba obujjanjabi obugendereddwamu HER2. Era basobola okubeera abakambwe ennyo.

Wansi waliwo emiwendo gy’emyaka 5 egy’okuwangaala okusinziira ku mutendera gwa kookolo. Zino za average zokka, kimanye nti embeera yo ssekinnoomu eyinza okuba ey’enjawulo.

Totya nnyo ennamba zino. Zino za average zokka okuva mu nkumi n’enkumi z’abantu. Endowooza yo ssekinnoomu ejja kusinziira ku bintu bingi, omuli engeri omubiri gwo gye gukwatamu obujjanjabi n’obulamu bwo okutwalira awamu. N’olwekyo, beera muggule n’omusawo wo ku mbeera yo n’okukeberebwa kwonna okw’enjawulo kw’oyinza okwetaaga.
