Ofuna ebizimba ebyewuunyisa ku lususu lwo? Kino kiyinza okuba nga kye bulwadde bwa Muir-Torre Syndrome?

Otandise mangu okufuna obuzimba obutonotono ku lususu lwo? Oyinza okulowooza nti bino bya bulijjo. Wabula oluusi enkyukakyuka zino mu lususu nazo ziyinza okukwatagana n’ebizibu eby’omunda. Leero tugenda kwogera ku mbeera etali ya bulijjo naye nga nkulu nnyo gye tulina okumanya. Kiyitibwa obulwadde bwa Muir-Torre Syndrome.

Obulwadde bwa Muir-Torre Syndrome kye ki? Mu ngeri ennyangu...

Muir-Torre Syndrome mbeera ya buzaale etali ya bulijjo eyongera ku bulabe bw’okufuna kookolo ow’ebika eby’enjawulo mu bulamu bwo. Abantu abalina obulwadde buno batera okufuna ebizimba by’olususu, oba ebya kookolo oba ebitali bya bulabe (i.e., ebitali birungi) mu lususu lwabwe. Era bayinza okufuna kookolo omu oba eziwera munda mu mubiri naddala mu nkola y’olubuto n’ekyenda .

Lowooza ku kino, omubiri gwaffe gukoleddwa mu bukadde n’obukadde bw’obutoffaali obutonotono. Obutoffaali buno bwe bwawukana, oluusi enkyukakyuka entonotono (enkyukakyuka) mu buzaale zisobola okubaawo. Ekyo kye kireeta enkyukakyuka eno mu buzaale.

Kale obulwadde bwa Muir-Torre Syndrome bwe bumu ne Lynch Syndrome?

Ebiseera ebisinga, yee. Obulwadde bwa Moore-Torre butwalibwa ng’enkyukakyuka mu bulwadde bwa Lynch . Obulwadde bwa Lynch syndrome era mbeera eyongera ku bulabe bwa kookolo olw’enkyukakyuka mu buzaale eziwerako. Oluusi abasawo era bakiyita kookolo w’olubuto n’omumwa gwa nnabaana (Hereditary Non-Polyposis Colorectal Cancer) (HNPCC). Kino kitegeeza nti kookolo akula mu kyenda ekinene nga talina ‘polyps’. Kale, Moore-Torre kitundu kya Lynch syndrome ekiraga engeri ez’enjawulo ez’olususu.

Embeera eno ya bulijjo etya? Kino tusaanidde okukyeraliikirira mu Sri Lanka?

Obulwadde bwa Moore-Torre mu butuufu mbeera etali ya bulijjo nnyo . Abantu nga 200 bokka be baakakwatibwa mu nsi yonna. Kyokka kino tekitegeeza nti tetusaanidde kukimanya. Abantu nga 9.2% abalina `HNPCC` bayinza okulaga ebifaananyi bino ebya Moore-Torre. Era kirabika kikwata abasajja katono okusinga abakazi (kwe kugamba, abakazi nga 2 ku buli basajja 3). Wadde nga tewali bibalo bituufu ku bantu bameka abali mu Sri Lanka, kikulu okumanya embeera ng’ezo.

Bubonero ki obulaga obulwadde bwa Moore-Torre syndrome? Tukitegeera tutya?

Kino kisinga kuva ku kulabika kw'ebizimba oba enkyukakyuka ku lususu n'obubonero bwa kookolo ow'omunda . Oluusi ebizibu by’olususu bisobola okubaawo nga kookolo ow’omunda tannabaawo, mu kiseera kye kimu oba oluvannyuma lw’okukula. Kyokka, enkyukakyuka mu lususu zitera okuba akabonero akasooka okwetegereza . Kookolo omulala ayinza obutalaga bubonero bwonna mu ntandikwa.

Nkyukakyuka ki z’osobola okulaba ku lususu?

Bino wammanga biyinza okulabibwa ku lususu lw’omuntu alina obulwadde bwa Moore-Torre syndrome:

• Sebaceous adenomas: Zino ze zisinga okutawaanya olususu (80% - 99%). Bino bizimba ebitali bya kookolo (benign). Zikula mu nseke eziyitibwa sebaceous glands, nga zino ze nnywanto z’amafuta mu lususu lwaffe. Zitera okusangibwa ku mutwe ne mu bulago, era mu bantu abalina obulwadde bwa Moore-Torre, zisinga kusangibwa mu kifuba, mu lubuto, mu bisambi, n’omugongo . Ziringa ebizimba ebitonotono, ebikalu, ebya kyenvu oba ebya langi y’olususu .
• Sebaceous carcinoma: Kino kizimba kya kookolo (ekizibu) ekikula mu nseke z’amasavu. Kiyinza okulabika ng’ekizimba ekiyitibwa sebaceous adenoma. Naye busaasaana mangu naddala okwetooloola ebikowe by’amaaso . Ebizimba bino biyinza okuvaamu omusaayi oba okukulukuta ekintu ekirimu ekikuta.
• Keratoacanthoma: Kino kika kirala eky’ekizimba ky’olususu. Buyinza okukula ku mutwe, mu bulago, omugongo n’emikono okumpi n’enkwaso z’enviiri. Kiyinza okuba nga kya kookolo oba ekitali kya kookolo . Kiringa ekizimba ekitono ekyekulungirivu, oluusi nga waggulu waliwo emisuwa egy’omusaayi egirabika, ate wakati nga waliwo ekikonde kya keratin . Kikula mangu nnyo, nga kiweza sentimita nga 3 mu wiiki ntono, n’oluvannyuma ne kikendeera mpolampola okumala emyezi oba emyaka. Wayinza okubaawo ekimu oba ebisingawo.
• Fordyce spots: Olw'okuba endwadde z'amasavu zitera okwenyigira mu bulwadde bwa Moore-Torre syndrome, abasawo abamu batwala "Fordyce spots" zino ng'akabonero. Zino nnywanto z’amasavu ezigulumivu, ezigaziye katono era nga zirabika mu bitundu ebitaliimu nviiri, gamba ng’okwetooloola emimwa . Okunoonyereza kulaga nti zisinga kubeera mu bulwadde bwa Moore-Torre syndrome.

Jjukira nti bw’olaba ekizimba ekipya oba okukyuka nga kino ku lususu lwo naddala nga lukula mangu, nga lukyuka langi oba nga luvaamu omusaayi, mazima ddala olina okulaba omusawo.

Kookolo ki akwatagana n’obulwadde bwa Moore-Torre?

Ebika bya kookolo eby’enjawulo bisobola okubaawo n’obulwadde buno. Kookolo asinga okulabika n’obubonero bwayo bwe buno:

• Kookolo w’olubuto n’omumwa gwa nnabaana: Kino kye kika kya kookolo ekisinga okubeerawo . Bukwata abantu nga kitundu ku bantu bonna. Kiva ku kukula kw’obutoffaali bwa kookolo mu kisenge ky’ekyenda ekinene oba eky’omu lubuto. Okwawukana ku ekyo, ne Moore-Torre, kookolo ono asobola okukula emyaka 15-20 nga bukyali okusinga bulijjo, ebiseera ebisinga nga wa myaka 50. Era asobola okusaasaana amangu . Obubonero buno mulimu okulumwa olubuto, okuzimba, enkyukakyuka mu mize gy’ekyenda, n’omusaayi mu musulo .
• Kookolo w’olubuto: Ono naye kookolo atera okulabibwa ku Moore-Torre. Obubonero buyinza okuli okulumwa olubuto, okuzimba, omusaayi mu musulo, okukaluubirirwa okugaaya emmere, okuziyira, n’obutayagala mmere .
• Kookolo w’enkola y’omusulo:Era eyitibwa `(Kkookolo w'omusulo)` oba `(kookolo ow'ekiseera)`. Kino kikosa oluwuzi lw’omusulo. Kiyinza okuleeta obulumi ng'ofulumya omusulo n'omusaayi mu musulo .
• Kookolo w’omu lubuto: Ono ye kookolo akula mu nnabaana, ekitundu eky’omunda mu nnabaana . Kiyinza okuvaako okulumwa olubuto olwa wansi, okulumwa ekisambi, n’okufulumya amazzi mu bukyala oba okuvaamu omusaayi mu ngeri etaali ya bulijjo .

Okugatta ku ekyo, ebika bya kookolo ebirala ebiwerako biyinza okuba nga bikwatagana n’obulwadde buno, omuli:

• Kookolo w’enkwaso
• Kookolo w’enseke
• Kookolo w’ekibumba
• Kookolo w’ekibumba
• Kookolo w’ekyenda ekitono
• Kookolo w’ekibumba
• Kookolo w’amawuggwe
• Kookolo w’omusaayi
• Waliwo kookolo w’obwongo n’ebika ebirala.

Olukalala luno luyinza okulabika ng’olw’entiisa. Naye ekikulu kiri nti kookolo ono yenna si nti ajja kukula mu buli muntu. Era, singa zizuulibwa nga bukyali, zisobola okujjanjabibwa .

Lwaki obulwadde buno obwa Moore-Torre bubaawo? Kiki ekivaako?

Mu ngeri ennyangu, obulwadde bwa Moore-Torrell syndrome buva ku nkyukakyuka mu emu ku buzaale bwo . Enkyukakyuka ze nkyukakyuka mu nsengeka ya DNA yaffe. DNA eno ekoppebwa obutoffaali bwaffe bwe bwawukana ne bukola obutoffaali obupya. Oluusi ensobi ziyinza okubaawo. Singa akatoffaali ng’ako akatali ka bulijjo kagenda mu maaso n’okwekutula, kayinza okuleeta endwadde ez’enjawulo, omuli ne kookolo.

Nkyukakyuka ki ez’obuzaale ezikwata ku kino?

Okusinga waliwo ebika bibiri:

• Obulwadde bwa Moore-Torre obw’ekika kya 1 (Type 1 MTS): Kino kiva ku nkyukakyuka mu emu ku buzaale obukola ensobi mu nsengeka ya DNA yo . Obuzaale buno bwe butasobola kuddaabiriza nsobi ezo, obutoffaali obutali bwa bulijjo bukuŋŋaanyizibwa mu bitundu by’omubiri. Mu bitundu 90%, obuzaale obuyitibwa MSH2 bukosebwa. Kyokka, obuzaale obulala obuwerako, gamba nga MLH1, MSH6, ne PMS2, buyinza okukwatibwako.
• Ekika kya 2 Moore-Torrell Syndrome (MTS): Kino kiva ku nkyukakyuka mu ggiini ya MUTYH. Ensengekera eno evunaanyizibwa ku kuddaabiriza okwonooneka kw’obusimu obuyitibwa oxidative damage ku DNA yaffe. Abantu nga kimu kya kusatu abalina MTS balina ekika kino. Oxidation ereeta enkyukakyuka mu molekyu ya DNA, ekiyinza okuvaako okukula kw’obutoffaali obutafugibwa (i.e., kookolo). Obuzaale obukyusiddwa bwe butasobola kuddaabiriza kwonooneka kuno, okwonooneka kusigalawo.

Kino kintu ekiva mu milembe?

Okusinga, yee, kya nsikirano . Kyokka oluusi omuntu asobola okufuna enkyukakyuka empya mu buzaale nga tewali muntu yenna mu maka yali agifunye. Abalwadde nga 60% basobola okuzuula ebyafaayo by’amaka eby’obulwadde bwa Moore-Torre. Kyokka, olw’okuba si buli muntu alina enkyukakyuka eno ey’obuzaale nti afuna obubonero, akakwate kano ak’amaka si bulijjo ke kalabika.

Abantu abamu bayinza okuba n’embeera eno nga tebalina bubonero, era bayinza n’obutagimanya. Ate era, oluusi abaserikale b’omubiri bwe banafuye, `MTS eno ekukuse` esobola okukolebwa. Abantu abamu embeera eno bagifunye oluvannyuma lw'okufuna `solid organ transplant` n'okumira eddagala eriziyiza obusimu obuziyiza endwadde.

Kino kiyisibwa kitya okuyita mu milembe?

• Ekika kya 1 MTS mbeera ya ``autosomal dominant''. Kino kitegeeza nti olina okuba ne kkopi emu yokka ey’obuzaale obukyusiddwa okusobola okusikira embeera eno. Singa omu ku bazadde bo aba n’enkyukakyuka eno ey’obuzaale, naawe olina emikisa gya 50% okugisikira. Kyokka engeri gy’ofunamu obubonero eyinza okuba ey’enjawulo ku muzadde gwe wasikira obuzaale.
• Ekika kya 2 MTS mbeera ya ``autosomal recessive``. Kino kitegeeza nti ggwe okusikira obulwadde buno, bazadde bo bombi balina okuba n’enkyukakyuka y’obuzaale y’emu. Kino tekitera kubaawo nnyo. Wabula abazadde abalina kkopi emu yokka ey’obuzaale buno obwa ``autosomal recessive`` bayinza obutaba na bubonero bwonna, kale bayinza obutamanya nti bulina.

Abasawo bazuula batya obulwadde bwa Muir-Torre Syndrome?

Bw’oba ​​olina ebizimba by’olususu ng’ebyo ebyogeddwako waggulu naddala ku mugongo gwo oba nga bibadde birabika ku myaka emito, omusawo ayinza okuteebereza nti olina obulwadde bwa Moore-Torrell syndrome. Era ajja kukubuuza ku bubonero obulala obuyinza okulaga kookolo ow’omunda, n’okumanya oba waliwo omuntu yenna mu maka go alina ebyafaayo bya kookolo.

Kino kikolebwa ku kukebera kwa ngeri ki?

Omusawo ayinza okusooka okukeberebwa okuwerako nga tannakuwa magezi kukebera buzaale. Okugeza nga:

• Immunohistochemistry (IHC): Akatundu akatono ak’ekizimba ku lususu lwo kakwatibwa, ne kasiigibwa langi ey’enjawulo, ne kakeberebwa wansi wa microscope okulaba oba sampuli eyo erimu enkyukakyuka ez’enjawulo mu buzaale.

Olw’ebyava mu kukebera kuno n’amawulire amalala, omusawo ayinza okukuwa amagezi okukebera obuzaale okukebera oba waliwo enkyukakyuka mu buzaale obukwatagana n’obulwadde bwa Moore-Torre. Olwo bajja kutwala sampuli y’omusaayi gwo banoonye enkyukakyuka mu buzaale obuddaabiriza obutakwatagana MSH2, MLH1, MSH6, PMS2, oba obuzaale obuddaabiriza base excision MUTYH.

Omuntu alina obulwadde bwa Moore-Torre syndrome yandibadde akeberebwa kookolo buli kiseera?

Kikulu nnyo abantu abalina obulwadde buno okwekebejjebwa buli kiseera , kubanga okuzuula amangu kyongera emikisa gy’obujjanjabi obulungi. Ebigezo abasawo bye bayinza okuteesa kuyinza okuli:

• Colonoscopy: Okukebera ekyenda ekinene.
• Upper endoscopy (EGD): Okukebera omumwa gwa nnabaana, olubuto n’ekitundu ekisooka eky’ekyenda ekitono.
• Okukebera enseke ( ku basajja) .
• Okukebera amabeere:Okukebera kookolo w’amabeere (ku bakyala) .
• Okukebera ekisambi ( ku bakyala) .
• Pap smear: Okukebera kookolo w’omumwa gwa nnabaana (ku bakyala) .
• Urine cytology: Ku kookolo w’enkola y’omusulo.
• Okukebera enkola y’ekibumba
• Okubala omusaayi mu bujjuvu (CBC) .
• Okukebera omubiri
• Okukebera olususu
• X-ray y’ekifuba

Omusawo wo y’ajja okusalawo emirundi gy’olina okukeberebwa kuno.

Bujjanjabi ki obuweebwa obulwadde bwa Moore-Torre syndrome?

Ekisinga okussa essira mu kuddukanya obulwadde bwa Moore-Torre kwe kuzuula n’okuggyawo kookolo singa abaawo . Ojja kwetaaga okwekebejjebwa kookolo buli kiseera n’okukwata ebitundu by’omubiri byonna ebiteeberezebwa. Singa omusawo asanga kookolo, ajja kumujjanjaba okusinziira ku kika kye n’omutendera gwe. Okulongoosa okuggyawo kookolo ebiseera ebisinga gwe mutendera ogusooka ogw'obujjanjabi .

Obujjanjabi obulala obwa kookolo buyinza okuli:

• Obujjanjabi bw’eddagala
• Obujjanjabi bw’amasannyalaze (radiation therapy).
• Obujjanjabi bw’obusimu
• Obujjanjabi bw’abaserikale b’omubiri
• Obujjanjabi obugendereddwamu
• Okukyusa obusigo bw’amagumba

Okugatta ku ekyo, eddagala eriyitibwa retinoid eriweebwa mu kamwa eriyitibwa isotretinoin liyinza okuyamba okuziyiza ebiwundu ebipya eby’olususu okutondebwawo. Singa okukebera ekyenda ekinene kisangamu ebiwuka by’ekyenda ekinene (colono polyps) bingi (ebiri mu bulabe obw’amaanyi obw’okufuna kookolo), omusawo ayinza okukuwa amagezi okukozesa eddagala eriziyiza kookolo, nga kino kizingiramu okuggyamu ekitundu oba kyonna eky’ekyenda ekinene.

Kiki ekitegeeza omuntu alina obulwadde bwa Moore-Torre?

Okuteebereza kwo kisinziira ku kookolo mmeka gw’ofuna n’obuwanvu bw’asaasaana. Ebibalo biraga nti abantu nga kitundu ku bantu abalina obulwadde bwa Moore-Torre syndrome bafuna kookolo asukka mu omu. Abasoba mu kitundu bafuna kookolo atambula (kookolo eyasaasaana mu bitundu by’omubiri ebirala era nga muzibu okujjanjaba).

Kookolo alina obulwadde bwa Moore-Torre syndrome atera okulabika nga bali ku myaka 50. Kookolo ono asobola okukula n’okweyongera amangu okusinga mu bantu bonna. N’olwekyo, okuzuula amangu kikulu . Ekirala, emikisa mingi egya kookolo okuddamu ne bw’aba amaze okuggyibwawo. N’olwekyo, okwekebejjebwa buli kiseera ng’omaze okujjanjabibwa kyetaagisa nnyo.

Waliwo engeri y’okuziyiza kino?

Ebiseera ebisinga si bwe kiri. Kino kiri bwe kityo kubanga mbeera gy’ozaalibwa nayo. Kyokka si buli muntu nti ajja kufuna obubonero. N’abo abafuna obubonero bayinza okukosebwa obulwadde buno okusinga bazadde baabwe. Bannasayansi tebannaba kukakasa lwaki kino kibaawo. Kyokka, kizuuliddwa nti embeera eno eyinza okweyongera singa abaserikale b’omubiri banafuye .

Okumanya nti olina enkyukakyuka eno mu buzaale kiyinza okukuyamba okusalawo ebimu ku ngeri y’okuziyiza. Okugeza, okukebera obuzaale n’okubudaabudibwa ku buzaale bisobola okukuyamba obutayisa embeera eno mu baana bo. Ate era, okukimanya kino kiyinza okukuyamba okuzuula kookolo nga bukyali n’otandika okujjanjabibwa, ne kiziyiza ebivaamu ebibi.

Wadde ng’obulwadde bwa Moore-Torre tebutera kubaawo, si kyangu kugumira bulwadde nga buno. Kiyinza okulabika ng’ekizibu okulwanyisa ekintu ekiyingidde mu DNA yaffe. Naye, okumanya ge maanyi . Bw’otegeera mu budde era n’ofuna obujjanjabi, ggwe n’omusawo wo musobola okwolekagana n’okusoomoozebwa kuno.

N’ekisembayo, obubaka obutwala awaka

Okay, kale ka tufunze ebimu ku bintu by'olina okujjukira okuva mu bye twogeddeko:

• Muir-Torre Syndrome mbeera ya buzaale eyongera obulabe bw’okufuna ebizimba by’olususu ne kookolo ow’omunda (naddala mu nkola y’okugaaya emmere).
• Bw’olaba ekizimba ekipya ekitali kya bulijjo ku lususu lwo naddala ku mugongo gwo, genda mangu omusawo amagezi. Kiyinza okuba nga si kintu, naye kirungi okukikebera.
• Eno nkyukakyuka ya bulwadde bwa Lynch syndrome. Omuntu yenna mu maka go bw’aba alina ebyafaayo bya kookolo, naye mubuulire omusawo wo.
• Okuzuula amangu n’okukeberebwa buli kiseera kikulu nnyo. Kino kiyinza okuyamba okuzuula kookolo nga bukyali n’okumujjanjaba obulungi.
• Okukebera obuzaale n’okubudaabudibwa kiyinza okuyamba okuzuula oba embeera eno eriwo era oba ekosa ab’omu maka.
• Totya, naye beera mwegendereza. Toli wekka era abasawo baliwo okukuyamba.

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