Raws li kev txheeb cais, mob qog noj ntshav mis yog hom mob qog noj ntshav tshaj plaws hauv cov poj niam. Triple-negative cancer mis yog ib hom mob hnyav tshaj plaws ntawm kev hloov ntawm tes. Hom mob neoplasm no tau pom nyob rau hauv 25% ntawm cov poj niam mob uas kuaj mob cancer mis.

TNBC yog dab tsi?

Triple-negative mis cancer (TNBC) yog hom mob qog noj ntshav txaus ntshai. Tus kab mob no tshwm sim los ntawm qhov tsis muaj receptors nyob rau hauv cov qog nqaij hlav rau steroid poj niam txiv neej cov tshuaj hormones uas tsim los ntawm zes qe menyuam, progesterone, ib qho protein uas ua rau kev faib, kev loj hlob thiab kev sib txawv ntawm cov hlwb epithelial. TNBC tshwm sim feem ntau ntawm cov poj niam hluas. Trip-negative (Triple negative) mob qog noj ntshav mis yog tus cwj pwm los ntawm kev ua haujlwm siab ntawm kev faib tawm ntawm tes, uas qhov ntim ntawm cov ntaub so ntswg nce nrog lawv txoj kev loj hlob sai thiab metastasis rau hauv nruab nrog cev. Malignant hlwb loj hlob thiab muab triple negative volumetric formations -yog li no lub npe.

Nyob rau hauv cov neeg mob uas muaj hom neoplasia, GDF11 protein, uas muaj peev xwm tiv thaiv cov phenotypic tshwm sim ntawm qee qhov kev hloov genome nyob rau hauv kev cuam tshuam ntawm lwm tus, yog tag nrho lossis ib nrab tsis ua haujlwm. Cov qog tsim tawm yog vim qhov inhibition ntawm cov txheej txheem ntawm tes tuag, uas lawv tawg mus rau hauv lub cev puag ncig los ntawm daim nyias nyias, thiab kev tawm tsam ntawm BRCA1 los tiv thaiv oncogene. Ib qho protein tsis paub qab hau nyob rau hauv daim ntawv tsis ua haujlwm tau sau rau hauv cov hlwb hloov pauv uas tuaj yeem tsim mus rau hauv cov qog nqaij hlav cancer. Qhov no ua rau muaj kev loj hlob sai ntawm cov qog uas tsis tswj tau. Hom mob khees xaws mis triple-negative feem ntau yog qib qis ductal carcinoma.

Kev faib kab mob: kwv yees rau txhua hom

  3. HER-2 / neu hom yog tus cwj pwm los ntawm kev txhoj puab heev, extragenically ywj siab malignant neoplasms ntawm qhov loj me thiab thaum ntxov lymphogenous metastasis. Kev kwv yees rau daim ntawv no ntawm triple-negative cancer misCov qog nqaij hlav feem ntau tsis zoo, vim tias cov qog nqaij hlav tuaj yeem tiv taus cov tshuaj hormones.
  4. hom basal-zoo li suav rau 70% ntawm cov carcinomas nrog rau qhov tsis zoo rau kev mus ncig. Cov neeg mob uas muaj daim ntawv no ntawm TNBC muaj qhov tsis zoo rov qab los.

Tseem muaj kev faib tawm ntawm TNBC los ntawm hom histological.

  1. Medullary hom muaj neoplasms nyob rau hauv daim ntawv ntawm strands thiab dav kab txaij, ntws zais. Nws feem ntau tsis meej pem nrog fibroadenoma.
  2. Metaplastic - ib pawg ntawm cov qog uas muaj cov yam ntxwv morphological. Tsis zoo li lwm hom mob qog noj ntshav mis, nws raug kuaj pom nyob rau theem siab thiab muaj qhov tsis zoo.
  3. Tsis zoo sib txawv ductal - neoplasia ntawm lub epithelium ntawm cov ducts, rhuav tshem nws hauv qab daus daim nyias nyias thiab tsim kev loj hlob nyob rau hauv ib puag ncig stroma.
  4. Adenocystic - yog qhov tsawg heev, muaj qib qis ntawm histoatological txawv, uas nyuaj rau kev kho.

Nyob rau hauv oncology, cov tshuaj kho mob yog raws li tag nrho cov yam ntxwv ntawm tus kab mob qhia rau tus kws kho mob.
