Kubva munaJuly 2016, BAC (Bronchioloalveolar carcinoma) izwi risisashandisi asi rakashandiswa pakati pegore ra2004 ne2011 kuti rirondedzere rimwe rutivi rwemapapu adenocarcinoma. Izvozvo zvakati, vamwe vepancologist vachiri kushandisa izwi iri, saka nhoroondo uye maitiro ezvakave zvakarongerwa seBAC zvicharondedzerwa pano.
BAC, apo yakarongwa pasi pemusoro uyu, dzimwe nguva yainzi "chakavanzika" kenza yemapapu.
Kuenzanisa 2 kusvika ku14 muzana yemakenza ose emapapu, zvishoma zvaizivikanwa nezvehutano hwechirwere ichi kupfuura mamwe madiki esiri duku emakirini emapapu .
Overview
Sezvambotaurwa pamusoro apa, BAC ikozvino yakadzorerwa pasi pekutungamirirwa kwemapapu adenocarcinomas , asi sezvo iri nguva dzimwe nguva richiri kushandiswa navanachiremba, icharondedzerwa mumamiriro ezvinhu akadaro. Muzvitsva zvitsva, BAC inogona kutumidzwa se "lepidic predominant adenocarcinoma" inobva pachimiro chekuwedzera chemuviri. BAC inokura mumasero pedyo nediki duku midzi ( alveoli ) munzvimbo dziri kunze dzemapapu. Inopararira pamwe chete nemucheka unoparadzanisa alveoli kana kuburikidza nemhepo. Kusiyana nemimwe mimwe yemapapu emapapu iyo inowanzopararira kusvika pamapapu ( pleura ) uye nedzimwe nzvimbo dzomuviri, BAC inopararira zvikuru mumapapu. Iyo inogona kuonekwa senzvimbo imwe chete mumativi emapapu, kana semapararira akapararira mumapapu ose.
Pane 2 mikuru mikuru yeBAC: kwete-mucinous BAC inowanzozivikanwa uye inowanikwa kakawanda muvanoputa, uye mucinous BAC, iyo isingawanzozivi uye inowanzowanika kune vasiri kusvuta.
Iyo Yakasiyana Sei Nevamwe Lungirini Lunguru?
BAC inowanzoita kuti vasati vasvuta, vakadzi, uye Asian (zvikurukuru kumabvazuva kweAsia) kupfuura mamwe maitiro emukenza wemapapu.
Chiitiko chayo chinenge chichiita sechichiwedzera, kunyanya pakati pevakadzi vaduku vasina kusvuta.
Zviratidzo
Zviratidzo zveBAC zvakafanana nezviratidzo zvinowanikwa nemamwe makondombera emapapu , uye zvinosanganisira kurwisana kunogara , kuchikwira ropa (hemoptysis), uye kurwadziwa kwepfupa. Asi yakanziwo "masquerader." Hazvishamisi kuti BAC isakanganiswa nepineumonia kana mamwe zvirwere zvemapapu zvisati zvaonekwa.
Kuziva
BAC kuongororwa kwakafananawo nekuongororwa kweimwe kenza yemapapu , ine zvishoma zvishoma. Kuongororwa kweBAC kunoda sampu yezvimedu, uye yakanaka-nenyuchi inoda kuputira inogona kupa hutachiwana hunenge hafu yenguva. Kusiyana nemamwe makondombera emapapu, uko PET inoongorora inobatsira kuwedzera kuT CT maonero ekugadzirisa kuti kenza iripo, PET maitiro haasi akavimbika. Kutarisa (zvikamu 1 kusvika ku 4 kana kuTMM kuenzaniswa) kwakafanana nekugadzira mamwe mhando yemukenza wemapapu .
Mishonga
Kuvhiya ndiko kurapa kusarudzwa kweBAC, uye kana bundu rimwe rinogona kubviswa, kazhinji kazhinji mukana wakanaka wekuti ucharapa. Zvinoratidzika kunge zvisinganyanyi kunetseka nekodhese chemotherapi , uye kune gakava pamusoro pekuti kana kwete adjuvant chemotherapy (chemotherapy inopiwa pamwe nekuvhiyiwa) inofanira kushandiswa nekuvhiyiwa.
BAC inoratidzika seinonyanya kunetseka nemishonga inofanirwa kuwanikwa, mishonga yakagadzirirwa kutarisa zvakasiyana-siyana zvekuchinja mukati mechirwere. Vanhu vane chirwere ichi chemapapu emapapu vanofanira kunge vane mazita ekuongorora maitiro (mashekeri ekufananidzira) akaitwa pamarara . Ikozvino kune mishonga inogamuchirwa kune aya makondombera emapapu ane EGFR mutations , ALK rearrangements , uye reRrang1 rearrangements , nemishonga inoshandiswa mumakiriniki ekuedza kune avo vane mamwe maitiro ekuchinja mumakumbo avo zvakare.
Kufamba kwemafupa kuri kutariswa sechimwe mushonga, uye kana kenza isingadzokeri mumapapu akawedzerwa, inopa imwe mukana wekugara kwenguva refu.
Prognosis
Pakati pese, kuponeswa kwepabonde kwakanyanya zviri nani kune BAC pane mamwe maitiro evanhu vasati vashoma kanzera yemapapu emapapu, kunyanya apo inobatwa kare uye imwe chete tsvina iripo. Mune rumwe ruzivo, avo vakaonekwa kuti vane BAC uye vane zvipembenene zvisingasviki masentimita matatu muhupamhi, vane makore mashanu ekupukunyuka kwemazana zana kubva muzana nekuvhiyiwa. Nezvikamu zvekupedzisira zvehutachiwana hwehutachiona hunosiyana zvikuru, zvichienderana nezvimwe zvinhu zvakadai sokuparadzaniswa kwemakumbo mulobe imwechete, kuputika kwemakirini, pamwe nekupararira kure kwechiremera.
