Zimene muyenera kudziwa zokhudza khansa ya m'mawere ya Luminal B!

Mwina mwamvapo zambiri zokhudza khansa ya m'mawere. Koma kodi mukudziwa kuti pali mitundu yosiyanasiyana ya khansa ya m'mawere? Chabwino, lero tikambirana za mtundu wapadera wotchedwa khansa ya m'mawere ya Luminal B. Dzinali lingamveke ngati lovuta pang'ono, koma musadandaule. Tikambirana za izi m'njira yosavuta kumva. Chifukwa kudziwa zinthu ngati izi kungakhale kofunikira kwambiri kwa inu ndi okondedwa anu.

Kodi Luminal B ndi chiyani? Kodi zinthu zake zapadera ndi ziti?

Mwachidule, Luminal B ndi mtundu wa khansa ya m'mawere yomwe ili ndi hormone receptor-positive (HR+). Izi zili choncho chifukwa mapuloteni ena (ma receptor) omwe ali mkati mwa maselo a khansa amamangirira ku hormone estrogen, zomwe zimapangitsa kuti khansayo ikule. Mawu oti "luminal" amatanthauza maselo omwe ali mkati mwa ducts za mkaka m'mawere anu. Taganizirani ngati mkati mwa chubu.

Tsopano tiyeni tiwone makhalidwe ena apadera a maselo a khansa ya Luminal B. Izi zili ngati khadi lozindikiritsa khansa iyi. Madokotala adzaphunzira makhalidwe amenewa mosamala kuti adziwe chithandizo chomwe chili chabwino kwa inu.

• Estrogen receptor positive (ER+): Ichi ndiye chizindikiro chofunikira kwambiri. Maselo a khansa ya Luminal B ali ndi mapuloteni otchedwa Estrogen Receptors (ER) omwe amatha kumangirira ku hormone ya Estrogen. Estrogen ndi hormone yomwe imapangidwa mwachibadwa m'thupi la mkazi. Chifukwa chake, hormone iyi ikamamatira ku maselo a khansa, khansa imakula bwino. Zili ngati kuthirira ndi kudyetsa chomera.
• Zochepa kapena Zoipa za ma receptor a Progesterone (PR- kapena PR yotsika): Poyerekeza ndi khansa ya m'mawere ya Luminal A, maselo a Luminal B ali ndi mapuloteni ochepa kwambiri, kapena nthawi zina palibe, omwe amamangirira ku mahomoni ena akuluakulu achikazi, progesterone.
• Mkhalidwe wa HER2 (HER2-positive (HER2+) kapena HER2-negative (HER2-)): Ichinso ndi chinthu chofunikira kwambiri. HER2 imayimira puloteni yotchedwa 'Human Epidermal Growth Factor Receptor 2'. Ichi ndi chinthu chomwe nthawi zambiri chimathandiza maselo kukula. Komabe, maselo ena a khansa ya m'mawere amapanga puloteni ya HER2 yambiri, mosalamulirika. Mu khansa ya Luminal B, puloteni iyi ya HER2 ikhoza kupezeka mopitirira muyeso (HER2-positive / HER2+), kapena ikhoza kupezeka pamlingo wabwinobwino (HER2-negative / HER2-). Njira zochiritsira zimasiyana malinga ndi mkhalidwewu.
• Mapuloteni ambiri a Ki-67 (Ochuluka mu Ki-67):Ki-67 ndi puloteni yapadera yomwe imapezeka m'maselo ogawa mofulumira okha. Khansa ya Luminal B nthawi zambiri imakhala ndi puloteni yochuluka kwambiri. Izi zimathandiza madokotala kumvetsetsa momwe maselo a khansa amagawikira mofulumira, zomwe zikutanthauza momwe khansa imakulira mofulumira. Ichi ndichifukwa chake khansa ya Luminal B nthawi zambiri imakula mofulumira kuposa khansa ya Luminal A.
• Giredi yapamwamba: Giredi ya khansa ndi momwe maselo a khansa amafanana kapena kusiyana ndi maselo athanzi akayang'aniridwa pogwiritsa ntchito maikulosikopu. Giredi yapamwamba imatanthauza kuti maselo a khansa ndi osiyana kwambiri ndi maselo athanzi ndipo amatha kukula ndikufalikira mwachangu. Khansa ya Luminal B nthawi zambiri imakhala yapamwamba kuposa ya Luminal A. Izi zikutanthauza kuti ndi yamphamvu kwambiri, imatha kukula, ndipo imatha kubwereranso pambuyo pa chithandizo.

Mungathe kuona zilembo zonsezi, manambala, ndi zidule (monga ER, PR, HER2, Ki-67) zikuwonjezera zambiri zokhudza maselo a khansa m'mawere anu. Ndi pofufuza izi zomwe madokotala angakonzekere chithandizo chapadera kwa inu ndi kuneneratu mtundu wa zotsatira zomwe mungayembekezere kuchokera ku chithandizocho.

Kodi khansa ya m'mawere ya Luminal B ndi yofala bwanji?

Tsopano mwina mukudzifunsa kuti, 'Ndi anthu angati omwe ali ndi matendawa?' Ndipotu, pakati pa 15% ndi 20% ya milandu ya khansa ya m'mawere yomwe yanenedwa padziko lonse lapansi ili ndi khansa yamtunduwu. Iyi ndi yochepa pang'ono poyerekeza ndi mtundu wofala kwambiri wotchedwa Luminal A. Koma, kuchuluka kumeneku sikuli kochepa, eti? Ndicho chifukwa chake ndikofunikira kudziwa izi.

Kodi zizindikiro za khansa ya m'mawere ya Luminal B ndi ziti?

Kawirikawiri, madokotala amatha kuzindikira izi musanayambe zizindikiro zilizonse, kudzera mu kuyezetsa mawere nthawi zonse , monga mammogram. Ichi ndichifukwa chake ndikofunikira kuchita mayeso awa mukadali ndi zaka. Koma nthawi zina mungakumane ndi chimodzi kapena zingapo mwa zizindikiro izi:

• Kapena ngati mwakhala mukugwiritsa ntchito mankhwala obwezeretsa mahomoni (HRT) kwa nthawi yayitali kuti muchepetse zizindikiro zokhudzana ndi kusamba.

Kuwonjezera pa izi, palinso zinthu zina zomwe zingawonjezere chiopsezo cha khansa ya m'mawere ya luminal B:

• Mbiri ya banja: Ngati amayi anu, mlongo wanu, mwana wanu wamkazi, kapena wachibale wanu wapafupi adadwalapo khansa ya m'mawere kapena khansa ya m'chiberekero, muli pachiwopsezo chachikulu.
• Zaka: Chiwopsezo chotenga khansa ya m'mawere chimawonjezeka munthu akakwanitsa zaka 50.
• Minofu ya m'mawere yokhuthala: Ngati minofu ya m'mawere ikuwoneka yokhuthala pa mammogram, imeneyonso ndi chiopsezo.
• Kusintha kwa majini: Kusintha kwa majini komwe kumachitika chifukwa cha cholowa m'majini ena, monga BRCA1 ndi BRCA2, kungapangitse kuti pakhale chiopsezo chachikulu cha khansa ya m'mawere.
• Chithandizo cha radiation chakale: Ngati mudalandirapo chithandizo cha radiation pachifuwa kapena m'mawere pazifukwa zina.

Kukhala ndi zinthu izi sizikutanthauza kuti mudzadwala khansa. Komabe, ndikofunikira kuzidziwa.

Kodi khansa ya m'mawere ya Luminal B imapezeka bwanji?

Tangoganizirani kuti muli ndi zizindikiro za khansa ya m'mawere, kapena mammogram ikusonyeza kuti pali chinachake chokayikitsa. Chinthu choyamba chomwe dokotala angachite ndikuchita mayeso a thupi. Izi zikutanthauza kuti adzayang'ana mabere anu kuti awone ngati pali zotupa kapena kusintha kwina.

Kenako, kuti adziwe zambiri, nthawi zambiri amayitanitsa mayeso ena owonjezera monga awa:

• Diagnostic mammogram: Izi ndi zatsatanetsatane kuposa mammogram wamba.
• Kujambula kwa Ultrasound: Izi zingathandize kudziwa ngati chotupa chili cholimba kapena chodzaza ndi madzi.
• Kujambula kwa MRI (Magnetic Resonance Imaging): Izi zingakhalenso zofunikira pazochitika zina zapadera.

Pambuyo pa mayeso amenewa, dokotala adzatenga chitsanzo cha minofu ya m'mawere (breast biopsy) ndikutumiza kuti akayesedwe. Iyi ndiyo njira yokhayo yodziwira ngati khansa ilipo kapena ayi, ndipo ngati ilipo, mtundu wake ndi uti. Kuyesa kumaphatikizapo kutenga chidutswa cha minofu kuchokera pamalo okayikitsa ndikutumiza ku labu kuti akayang'aniridwe ndi maikulosikopu.

Katswiri wa matenda, dokotala yemwe ndi katswiri wofufuza minofu, adzayang'ana chitsanzo cha minofu yanu kuti aone ngati pali maselo a khansa. Ngati maselo a khansa apezeka, adzachita mayeso a hormone receptor (a ER, PR) ndi mayeso a HER2 kuti adziwe mtundu wa khansa. Pa mayeso awa, omwe amagwiritsidwa ntchito kwambiri ndi mayeso otchedwa immunohistochemistry (IHC) . Izi zimagwiritsa ntchito utoto wa fluorescent ndi ma enzyme kuti awonetse mamolekyu enaake pa maselo a khansa. Nthawi zina, milingo ya Ki-67 imawunikidwanso motere.

Mayeso awa pa chitsanzo cha minofu yanu angathandize gulu lanu lachipatala kudziwa chithandizo chomwe chingakugwireni bwino, komanso kukupatsani lingaliro la momwe khansa ingabwererenso mutalandira chithandizo.

Kodi Luminal B imagwiritsidwa ntchito bwanji pochiza khansa ya m'mawere?

Chithandizo cha khansa ya m'mawere ya Luminal B chingasiyane malinga ndi munthu aliyense. Zimatengera zinthu zambiri, kuphatikizapo momwe mulili, gawo la khansa, momwe mulili ndi HER2 (HER2+ kapena HER2-), mulingo wanu wa Ki-67, komanso thanzi lanu lonse. Gulu lanu lachipatala lidzaganizira zonsezi kuti lipange dongosolo labwino kwambiri la chithandizo kwa inu.

Njira zazikulu zochizira zomwe zimagwiritsidwa ntchito ndi izi:

• Chithandizo cha mahomoni: Popeza Luminal B ndi khansa yomwe imakhudzidwa ndi mahomoni (HR+), iyi ndiyo njira yodziwika kwambiri yochizira. Izi zimagwira ntchito poletsa hormone estrogen kufika m'maselo a khansa, kapena pochepetsa kuchuluka kwa estrogen m'thupi. Mankhwala monga Tamoxifen ndi Aromatase Inhibitors amagwiritsidwa ntchito pa izi.
• Opaleshoni: Izi zimaphatikizapo kuchotsa maselo a khansa m'mawere.
• Kuchotsa Lumpectomy: Izi zimaphatikizapo kuchotsa chotupa cha khansa ndi minofu yathanzi yozungulira, zomwe zimapangitsa kuti bere lonse likhale lopanda vuto.
• Kuchotsa bere lonse: Izi zikuphatikizapo kuchotsa bere lonse.

Pa opaleshoni, ma lymph nodes omwe ali m'khwapa amatha kuchotsedwa kuti aone ngati khansa yafalikira.

• Chithandizo cha radiation:Pambuyo pa opaleshoni, chithandizo cha radiation chimaperekedwa kuti chiphe maselo onse a khansa otsala m'derali. Izi nthawi zambiri zimaperekedwa, makamaka ngati opaleshoni ya lumpectomy yachitika.
• Chithandizo cholunjika: Mtundu uwu wa chithandizo umayang'ana mamolekyu enaake omwe amathandiza maselo a khansa kukula. Mwachitsanzo, ngati khansa ya Luminal B ili ndi HER2-positive (HER2+), mankhwala omwe amalunjika ku puloteni ya HER2 (monga Trastuzumab) angaperekedwe. Izi zimatsimikiziridwa ndi gawo la khansa ndi ma receptor ena.
• Chemotherapy: Mankhwala othandizira a chemotherapy angaperekedwe kuti aphe maselo a khansa omwe sanaphedwe ndi mankhwala ena, kapena kuti aletse khansa kufalikira ku ziwalo zina za thupi.
