Engeri empya ey’okuzuula kookolo: Buli kimu ekikwata ku kukebera kookolo mu mazzi!

Wali owuliddeko ku kigambo "liquid biopsy "? Oboolyawo omusawo wo akubuuliddeko, oba waliwo w’osomyeko. Eno nkola nkulu nnyo, mpya ey’okukebera okuzuula n’okujjanjaba kookolo. Kale, ka twogere ku nsonga eno mu ngeri ennyangu era mu ngeri entegeerekeka leero. Tewali kyakutya, kiringa mukwano gwo bw’akunnyonnyola ekintu.

Kino liquid biopsy kye ki? Kyangu nnyo!

Mu ngeri ennyangu, okukebera omusaayi mu mazzi kwe kukebera okutwala omusaayi omutono . Kino kisobola okuzuula oba waliwo ebizimba bya kookolo. Teebereza nti ekizimba kya kookolo bwe kikula, obutundutundu obutono obwakyo busobola okukutuka ne buyingira mu musaayi gwo. Ebitundu ebyo bye bizuulibwa okunoonyereza kuno okw’amazzi.

Ekigezo kino kinoonya ebintu bibiri ebikulu:

• Circulating Tumor Cells (CTCs): Buno butoffaali bwa kookolo obukutuka ku kizimba ne buyita mu musaayi gwo, ng’obukessi obutono.
• Circulating tumor DNA (ctDNA): Bino bitundutundu bya DNA ebikutuka ku butoffaali bwa kookolo ne biyingira mu musaayi. Nga bw’omanyi, DNA eringa ekitabo ekirimu obuzaale obufuga enneeyisa y’obutoffaali bwaffe. Kale, ebitundu bino ebya ctDNA bisobola okutubuulira bingi ku kookolo.

Okubeerawo kwa `(CTCs)` oba `(ctDNA)` zino mu musaayi gwo bukakafu nti waliwo ekizimba kya kookolo awalala mu mubiri gwo. Ate era, okuva ebitundu bino nabyo bwe biwa `( genetic information)` ya kookolo, kijja kuba kiyamba nnyo eri omusawo wo mu kusalawo obujjanjabi ki obusinga okukusaanira.

Okukebera ebitundu by’omubiri mu mazzi (liquid biopsy) kigezo kipya nnyo. Kirina obusobozi okuleeta enjawulo nnene mu kisaawe ky’okujjanjaba kookolo. Waliwo dda enkozesa eziwerako ezikkirizibwa ekitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala (FDA). Okunoonyereza ku nsonga eno kukyagenda mu maaso.

Njawulo ki eriwo wakati w’okukebera omubiri mu mazzi n’okukebera okwa bulijjo kwe tumanyi?

Oboolyawo owulidde ku by’okukebera ebitundu by’omubiri (biopsy) ebya bulijjo. Mu yo, omusawo aggya akatundu akatono butereevu mu kizimba kya kookolo n’akakebera mu laabu okulaba oba kalimu obutoffaali bwa kookolo.

Kyokka, mu kukebera omubiri mu mazzi, ekitundu ky’ekizimba tekitwalibwa butereevu . Wabula, ekozesebwa okunoonya obujulizi bwa kookolo, nga buno bwe butoffaali bwa kookolo ``CTCs`` oba DNA ya kookolo ``ctDNA`` bwe twayogeddeko emabegako, mu musaayi.

Mu kiseera kino okukebera ebitundu by’omubiri (routine biopsy) kitwalibwa ng’engeri esinga obulungi ey’okuzuula oba kookolo aliwo. Era kiyitibwa "omutindo gwa zaabu."

Mu liquid biopsy, ne bw’oba ​​olina kookolo, tewali bukakafu 100% nti ojja kusobola okuzuula obubonero bwayo mu musaayi gumu. Kyokka singa kookolo azuulibwa mu kitundu ky’omubiri ekiyitibwa liquid biopsy, amawulire g’awa ku butoffaali bwa kookolo ga muwendo nnyo, era gayinza okuyamba ennyo abasawo mu kutegeka obujjanjabi.

Mu mbeera ki okukebera omubiri mu mazzi ( liquid biopsy) kwe kukolebwa?

Omusawo ayinza okukuwa amagezi okukebera omubiri mu mazzi mu mbeera zino wammanga:

• Bw’oba ​​olina kookolo asaasaana mu bitundu by’omubiri gwo ebirala era ng’obujjanjabi bw’olina kati tebukola nga bwe kisuubirwa. Kookolo agenda mu bitundu ebirala (metastatic cancer) ye ngeri ya kookolo esinga okubeera ey’obukambwe era nga asaasaanidde mu mubiri gwo gwonna. Bwe busaasaana bwe buti, kiyinzika nnyo nti ebitundu bya kookolo bijja kukutuka ne biyingira mu musaayi gwo.

Omusawo ayinza okulagira okukebera ebitundu by’omubiri eby’amazzi okusobola okumanya ebintu nga:

• Salawo embeera y’okuteebereza: Okukebera amazzi mu bitundu by’omubiri (Liquid biopsies) kusobola okuzuula obutoffaali bw’ekizimba obutambula (CTCs) ku bika bya kookolo bingi . Omuwendo omutono ogw’obutoffaali bwa kookolo mu musaayi gulaga nti waliwo okuteebereza okulungi. Omuwendo omunene ogw’obutoffaali bwa kookolo gulaga nti obulwadde buno bubi nnyo. Kale, omusawo wo asobola okukola okukebera kuno buli luvannyuma lwa kiseera okulondoola embeera yo n’okutereeza obujjanjabi bwo bwe kiba kyetaagisa.
• Okusalawo ku bujjanjabi: Waliwo obujjanjabi obugenderera obutoffaali bwa kookolo obumu bwokka (targeted therapy). Kino kitegeeza nti singa akatoffaali ka kookolo kalina ensobi ezimu (mutation) mu DNA yaako, kasobola okuweebwa eddagala eryetongodde eryategekebwa okulumba ensobi eyo. Okukebera ebitundu by’omubiri (liquid biopsy) kuyinza okuzuula ensobi zino. Olwo omusawo wo asobola okukuwa obujjanjabi obukwata ku nsobi eyo.

Ate era osobola okulongoosebwa mu mazzi ne bwe kiba nti okukebera kookolo bulijjo tekisoboka kuzuula kookolo. Kino kiri bwe kityo kubanga okukebera ebitundu by’omubiri bulijjo nkola ya kuyingirira nnyo okusinga okukebera ebitundu by’omubiri mu mazzi. Oyinza obutaba mulamu bulungi okusobola okwekebejjebwa. Oba okusinziira ku kifo ekizimba we kiri, kiyinza okuba ekizibu okuggyamu ekitundu kyakyo nga tekikwonoona bitundu bikulu ebiriraanyewo.

Biki ebikeberebwa eby’amazzi (liquid biopsy tests) ebikkirizibwa FDA?

Ebigezo ebikkirizibwa ekitongole kya U.S. Food and Drug Administration (FDA) bye bino ebinoonyezeddwa ennyo era nga bikakasiddwa nti tebirina bulabe era bituufu. Ebigezo by’omubiri ebiwerako eby’amazzi (liquid biopsy tests) bikyali mu mutendera gw’okunoonyereza. Waliwo ebigezo ebikulu bina ebikkirizibwa mu kiseera kino ekitongole kya FDA:

1. Okukebera Cell Search® Circulating Tumor Cell (CTC): Kino kikebera CTCs. Ebbeere, ensekeKino kikozesebwa okufuna ekirowoozo ku mbeera y’abantu abalina kookolo asaasaanidde mu kyenda oba mu nseke mu biseera eby’omu maaso. Bwe wabaawo CTC ntono mu musaayi, ekyo kabonero kalungi. Bwe wabaawo CTC nnyingi, ekyo kiba kizibu katono.

2. cobas® EGFR Mutation Test v2: Kino kikebera ctDNA. Kizuula enkyukakyuka mu buzaale obuyitibwa EGFR, naddala mu kookolo w’amawuggwe ow’obutoffaali obutali butono (NSCLC). Amawulire gano gasobola okuyamba omusawo wo okusalawo obujjanjabi ki obusinga okutunuulira enkyukakyuka eyo.

3. Guardant360® CDx: Kino nakyo kinoonya ctDNA. Kikozesebwa okuzuula obulema mu buzaale obutera okubeera mu butoffaali bwa kookolo. Kino kiyamba omusawo okulonda obujjanjabi obusinga okukola obulungi.

4. FoundationOne® Liquid CDx: Kino nakyo kinoonya ctDNA. Kino kiyamba okuzuula obulema mu buzaale (mutations) mu bika bya kookolo eby’enjawulo. Kino kiyamba omusawo okusalawo obujjanjabi obusinga okusaana.

Okukebera omubiri mu mazzi ( liquid biopsy) kukolebwa kutya? Kiruma?

Okukebera omusaayi mu mazzi ( liquid biopsy ) kwekebeza musaayi kwangu nnyo . Nga bwe wandiwadde omusaayi okukeberebwa buli kiseera. Omusawo oba nnansi ajja kuggya omusaayi ku mukono gwo n’agusindika mu laabu okukeberebwa.

Mu laabu, ekyuma kyawula omusaayi gwo mu bitundu by’obutoffaali (ekitundu ekigumu) ne plasma (ekitundu ekinywevu). Olwo, omukugu mu by’endwadde, omukugu eyatendekebwa okwekenneenya sampuli z’amazzi n’ebitundu by’omubiri, anoonya obubonero bw’obulwadde mu kitundu kya plasma, obuyitibwa CTCs oba ctDNA.

Kino kiruma? Nedda, okukebera omusaayi mu mazzi kiwulira ng’okugaba omusaayi. Empiso bw’eyingizibwa mu mukono gwo, oyinza okuwulira ng’owunya katono, ng’okulumwa enseenene. Naye obutabeera bulungi obwo bugenda mangu.

Ekimu ku birungi ebiri mu kukebera ebitundu by’omubiri mu mazzi kwe kuba nti nkola ya kuyingirira nnyo era eruma okusinga okukebera omubiri okwa bulijjo.

Ebyava mu kukebera kuno byogera ki?

Ebyava mu kukeberebwa bikugamba oba omusaayi gwo gulimu oba `(CTCs)` oba `(ctDNA)` (`positive`) oba nedda (`negative`) .

• Singa ekivaamu kiba ``positive`` , kitegeeza nti ebintu ebyogeddwako biri mu musaayi. Olwo, okukebera kuno era kuyinza okuyamba okuzuula ekika kya kookolo ky’olina. Okusingira ddala, okukebera okunoonya ``(ctDNA)`` era kusobola okuzuula obulema mu buzaale obutera okukwatagana n'ebika bya kookolo ebimu.

Kitwala bbanga ki okufuna ebyavaamu? Okukebera omubiri mu mazzi kutuufu kwenkana wa?

Ebiseera ebisinga ebyava mu kukeberebwa birina okufunibwa mu wiiki bbiri oba ssatu .

Kati katutunuulire obutuufu bwa kino. Ebigezo by’amazzi (liquid biopsy tests) ebikkiriziddwa ekitongole kya FDA, bikoleddwa ku ki, era bikola omulimu ogwo gwennyini.

• Omusawo asobola okufuna ekirowoozo ku mbeera y’obulwadde bwo mu biseera eby’omu maaso n’okulondoola embeera y’obulwadde bwo ng’ayita mu kukeberebwa kwa `(CTC)`.
• Olw'okuba okukebera ``(ctDNA)`` kusobola okuzuula obulema mu buzaale mu DNA y'obutoffaali bwa kookolo, kiyamba mu kusalawo ku bujjanjabi.

Naye, okukebera omubiri mu mazzi bulijjo tekuyinza kwesigamwako okuzuula kookolo n’obukakafu 100% . Okukebera omubiri (standard biopsy) kwetaagibwa okukakasa nti waliwo kookolo.

Okukebera ebitundu by’omubiri (liquid biopsy tests) mu kiseera kino kitundu kya kunoonyereza n’okukulaakulanya ennyo. Obusobozi bw’okuzuula n’okulondoola kookolo ng’okozesa okukebera omusaayi okwangu kintu kinene. Okunoonyereza kugenda mu maaso okukola ebyuma ebikebera omubiri (liquid biopsy tests) ebisobola okuzuula kookolo nga tannaba na kukula. Wabula, okunoonyereza okusingawo kwetaagibwa okutegeera obusobozi obujjuvu obw’okukebera ebitundu by’omubiri eby’amazzi. Edda, bayamba okuzuula ebika bya kookolo ebimu n’okusalawo ku bujjanjabi mu mbeera entongole. Mu biseera eby’omu maaso, boolekedde okufuna emiganyulo egy’amaanyi n’okusingawo.

N’ekisembayo, ebintu bye tulina okujjukira

Okay, kale twogedde nnyo ku liquid biopsy. Bino bye bintu ebitonotono by’olina okujjukira:

• Liquid biopsy kye kigezo ekipya ekinoonya obubonero bwa kookolo mu musaayi .
• Kino kisobola okuzuula `(CTCs)` (obutoffaali bwa kookolo) ne `(ctDNA)` (DNA ya kookolo).
• Tewali buzibu bunene oba obulumi nga okukebera ebitundu by’omubiri bulijjo.
• Kino kiyamba okufuna ekirowoozo ku mbeera ya kookolo mu biseera eby'omu maaso n'okusalawo ku bujjanjabi .
• Ebimu ku bigezo ebikkirizibwa FDA byaliwo dda.
• Kyokka, okusobola okukakasa obulungi kookolo, kiyinza okwetaagisa okukebera kookolo bulijjo .
• Ono tekinologiya akyakulaakulana era ayinza okuba ow’omugaso ennyo mu biseera eby’omu maaso.

Ekisinga obukulu, bw’oba ​​olina ekibuuzo kyonna oba ekikweraliikiriza ku nsonga eno, mazima ddala yogerako n’omusawo wo. Asobola okukunnyonnyola buli kimu mu ngeri ekusinga obulungi.

Nsuubira nti amawulire gano ga mugaso gy'oli! Sigala nga oli mulamu bulungi!
