Ngā momo rongoā ārai mate mō te maimoatanga matepukupuku
Ko te immunotherapy he huarahi maimoatanga mate pukupuku e whakamahi ana i te pūnaha ārai mate hei tautuhi me te whawhai ki ngā pūtau mate pukupuku. Kāore i rite ki te chemotherapy, e whakaeke ana i ngā pūtau tere wehewehe, ki te radiotherapy rānei, e kino ana te DNA pūtau pukupuku ki te radiation, ka mahi te immunotherapy mā te "whakatairanga," te "tohutohu," te "tuku i ngā aukati" rānei i te urupare ārai mate, ka nui ake te whai huatanga o te tinana ki te whakangaro i te mate pukupuku. I ngā tau tata nei, kua noho te immunotherapy hei putanga nui i roto i te oncology nā te mea ka taea e ia te whakarato urupare roa ki ētahi tūroro, tae atu ki ngā mate pukupuku i uaua ki te rongoā i mua.
Heoi, kāore te rongoā ārai mate e pai mō ngā momo mate pukupuku katoa, mō ngā tūroro katoa rānei. Ka rerekē pea ngā pānga taha i ngā rongoā tuku iho, e pā ana ki te kaha rawa o te pūnaha ārai mate. Nō reira, ko te kōwhiringa o te rongoā ārai mate e ahu mai ana i te momo mate pukupuku, te wāhanga o te mate, te āhua o te tūroro, me ngā tohu koiora motuhake. Ko ngā momo rongoā ārai mate e whai ake nei e whakamahia ana i roto i te rongoā mate pukupuku.
1. Ngā Ārai Ārai Pūnaha Ārai Mate (Ngā Ārai Ārai Pūnaha Ārai Mate)
Ko tētahi o ngā momo rongoā ārai mate tino rongonui ko ngā aukati ārai mate. He "pūwāhi tirotiro" tō te pūnaha ārai mate, arā, ngā tikanga taiao e ārai ana i ngā urupare ārai mate nui rawa ka kino pea ki ngā kiko o te tinana. He maha ngā wā ka whakamahia e ngā pūtau matepukupuku ēnei pūwāhi tirotiro hei "huna" mai i te whakaekenga a ngā pūtau-T (ngā pūtau ārai mate whakamate).
Ka mahi ngā aukati tirotiro mā te aukati i ngā pūmua tirotiro motuhake, ka taea ai e ngā pūtau-T te whakahohe anō me te whakaeke i ngā pūtau matepukupuku. Ko ngā whāinga e rua e tino kitea ana ko:
– PD-1/PD-L1 (Programmed Death-1 / Ligand-1): Ka taea e ngā pūtau matepukupuku te whakaatu i te PD-L1 hei "whakaweto" i ngā pūtau-T. Ka taea e ngā rongoā e aukati ana i te PD-1, te PD-L1 rānei te āwhina ki te whakatuwhera anō i te mahi a ngā pūtau-T.
– CTLA-4 (Cytotoxic T-Lymphocyte–Associated Protein 4): He aukati a CTLA-4 i te whakahohenga o ngā pūtau-T, inā koa i ngā wāhanga tōmua o te urupare ārai mate.
Ka whakamahia ngā aukati tirotiro hei rongoā i ngā momo mate pukupuku, tae atu ki te melanoma, te mate pukupuku pūkahukahu, te mate pukupuku tākihi, te mate pukupuku tōngāmimi, me ētahi mate pukupuku o te upoko me te kaki. Ko te painga o tēnei rongoā ko te kaha ki te whai hua mō te wā roa, engari ko ngā mōrearea ko ngā pānga taha ā-tinana pērā i te colitis, te niumōnia, ngā mate tairoi, tae atu ki te hepatitis ā-tinana.
2. Te Whakaora Pūtau-T CAR (Te Whakaora Pūtau-T CAR)
He tino whaiaro te rongoā pūtau-T a te CAR. I roto i tēnei rongoā, ka tangohia ngā pūtau-T o te tūroro mai i te toto, kātahi ka whakarerekētia i roto i te taiwhanga kia whai kaiwhakawhiwhi motuhake e kiia nei ko te Chimeric Antigen Receptor (CAR). Kua hangaia tēnei kaiwhakawhiwhi hei kite i ngā antigens motuhake i runga i te mata o ngā pūtau matepukupuku. Kia whakarerekētia, kia whakanuia hoki, ka whakahokia ngā pūtau-T ki te tinana o te tūroro kia rapua me te whakangaro i ngā pūtau matepukupuku.
Kua tino angitu te rongoā pūtau-T a te CAR, inā koa i roto i ētahi mate pukupuku toto, pēnei i:
– te mate toto toto nui whakapeka (ALL) i ētahi wā,
– ētahi lymphoma kore-Hodgkin,
– te myeloma maha i roto i ētahi tohu.
Heoi anō, ka pā mai pea ngā pānga kino kino ki tēnei rongoā, pērā i te Cytokine Release Syndrome (CRS), e hua ai te kirika nui me te toto toto iti, tae atu ki ētahi mate pūnaha io. Hei tāpiri, he uaua te utu me te wātea o ngā whare nā te uaua o te tukanga.
3. Ngā Paturopi Monoclonal
Ko ngā paturopi monoclonal he pūmua hangai kua hangaia hei piri ki ngā ūnga motuhake o ngā pūtau matepukupuku. Mā te "tāpiri" i ngā pūtau matepukupuku, ka āwhina ngā paturopi i te pūnaha ārai mate ki te kite i ngā pukupuku, ki te whakararuraru rānei i ngā tohu tipu matepukupuku.
He maha ngā huarahi e mahi ai ngā paturopi monoclonal i roto i te mate pukupuku:
1. Ngā paturopi e aro ana ki te kaiwhakawhiwhi: ka aukati i ngā tohu tipu i roto i ngā pūtau matepukupuku.
2. Ngā paturopi e whakaoho ana i te whakangaromanga e te pūnaha ārai mate: ka kukume i ngā pūtau ārai mate ki te whakaeke i ngā pūtau kua tohua.
3. Hononga paturopi-rongoā (ADC): ka haria e ngā paturopi te "taumaha" o ngā rongoā chemotherapy ki ngā pūtau matepukupuku kia pai ake ai te aro atu ki a rātou.
4. Te rongoā ārai mate irahiko: ka haria e ngā paturopi ngā matū irahiko ki te pukupuku.
E whakamahia whānuitia ana ngā paturopi monoclonal hei rongoā i ngā momo mate pukupuku, tae atu ki te mate pukupuku ū , te lymphoma, te mate pukupuku colorectal, me ētahi atu. He rerekē ngā pānga taha, mai i ngā tauhohenga werohanga me ngā ponana kiri ki te kino o ngā okana, i runga i te ūnga e ūnga ana.
4. Ngā Kano Ārai Matepukupuku
Ko te whāinga o ngā kano ārai mate pukupuku he whakaoho i te pūnaha ārai mate kia kite i ngā pūmua mate pukupuku. He rerekē ki ngā kano ārai mate hei ārai i ngā mate pipiri , e rua ngā wāhanga whānui o ngā kano ārai mate pukupuku:
– Ngā kano ārai mate: te ārai i te mate pukupuku i puta mai i ētahi huaketo. Ko te tauira rongonui ko te kano HPV, e whakaiti ana i te mōrearea mate pukupuku o te kaki me ētahi mate pukupuku o te upoko me te kaki, tae atu ki te kano ārai mate hepatitis B hei whakaiti i te mōrearea o te mate pukupuku ate.
– Ngā kano ārai mate: ka hoatu ki ngā tūroro kua pāngia e te mate pukupuku hei āwhina i te pūnaha ārai mate ki te whakaeke i te pukupuku.
Ko ngā kano ārai mate e aro ana ki ngā pūmua motuhake ki te pukupuku o te tūroro, ki ngā pūmua rānei e kitea ana i ētahi momo mate pukupuku. Ka rerekē pea ngā urupare, ā, kei te haere tonu ngā rangahau ki te whakapai ake i te whai huatanga, tae atu ki te whakamahi i ngā huinga aukati tirotiro.
5. Te Whakaora Hitokine
Ko ngā cytokine he ngota tohu e whakamahia ana e ngā pūtau ārai mate hei whakawhitiwhiti kōrero me te whakahaere i ngā urupare ārai mate. I roto i te rongoā mate pukupuku, ka taea te tuku i ētahi cytokine hei whakarei ake i te mahi a te pūnaha ārai mate.
Ko ngā tauira o ngā cytokine kua whakamahia whānuitia ko:
– Interleukin-2 (IL-2): ka taea te whakaoho i te tipu o ngā pūtau-T me ngā pūtau-NK (kaikōhuru tūturu). Kua whakamahia mō ētahi mate pukupuku tākihi me ngā melanoma.
– Interferon alpha: ka taea e ia te whakarei ake i te urupare ārai mate, ā, he pānga ārai-whanui hoki ki ētahi mate pukupuku.
He whai hua pea te rongoā cytokine mō ētahi tūroro, engari he maha ngā pānga taha ā-tinana pērā i te kirika, te ngenge nui, te toto toto iti, me te ngoikore o te mahi a ngā okana, nō reira kua whiriwhiria ake tōna whakamahinga ināianei, ā, he maha ngā wā ka whakakapia e ngā rongoā ārai mate motuhake ake.
6. Te Whakaora i te Huaketo Oncolytic
Ka whakamahia e te rongoā huaketo oncolytic ngā huaketo kua whakarerekētia hei pangia me te whakangaro i ngā pūtau matepukupuku, me te "whakaara" anō hoki i te pūnaha ārai mate kia kite i te pukupuku. Ina pakaru (ka pakaru) ngā pūtau matepukupuku e te huaketo, ka tukuna ngā antigens pukupuku, ka puta he urupare ārai mate whānui.
He mea ātaahua tēnei rongoā nā te mea e rua ngā tikanga e mahi ai: te whakangaromanga tika o ngā pūtau pukupuku me te whakahohe i te pūnaha ārai mate pukupuku. Ko te tikanga ka tukuna mā te werohanga tika ki roto i te pukupuku. Kei te haere tonu ngā rangahau hei whakawhānui ake i tōna whakamahinga puta noa i ngā momo mate pukupuku, me te whakakotahi i tēnei me ngā aukati tirotiro mō te urupare kaha ake.
7. Te Whakaora TIL me Ētahi Atu Whakaora Ārai Mate Pūtau Whāngai
Haunga te CAR T, kei reira ētahi atu huarahi e kiia nei ko te rongoā pūtau whāngai, pērā i te rongoā lymphocytes whakauru-tumor (TIL). I roto i te rongoā TIL, ka tangohia e ngā tākuta ngā pūtau ārai mate kei roto i te kiko pukupuku (ngā lymphocytes e "uru ana" ki te pukupuku), ka whakanuia i roto i te taiwhanga, kātahi ka whakahokia ki te tūroro. Nā te mea kua "whakangungua" ēnei pūtau ki te kite i te taiao pukupuku, ka whai hua pea tēnei rongoā i ētahi wā, inā koa i roto i te horopaki o te rangahau me ētahi pokapū mate pukupuku.
Tērā anō hoki ngā huarahi hei hanga i ngā pūtau-T me ētahi atu kaiwhakawhiwhi (hei tauira, ngā pūtau-T i hangaia e te TCR), e aro ana ki ngā antigens pukupuku mā te tikanga mōhio rerekē i ngā CAR.
Te Whakaora Ārai Mate Whakakotahi me ngā Wero o te Ao kei te heke mai
I roto i ngā mahi haumanu , he maha ngā wā ka honoa te rongoā ārai mate me te chemotherapy, te radiotherapy, te rongoā arotahi, te whakakotahitanga rānei o ngā rongoā ārai mate. Ko te whāinga he whakanui ake i te tūponotanga o te urupare, te wikitoria i te ātete, me te whakawhānui ake i te maha o ngā tūroro ka whai hua.
Heoi anō, kei te mau tonu ngā wero nui, pērā i:
– kāore ngā tūroro katoa e aro mai,
– me whai tohu koiora tika te matapae urupare (hei tauira, te whakaaturanga PD-L1, te taumahatanga whakarerekētanga pukupuku, te teitei o te MSI i roto i ētahi mate pukupuku),
– me aro turuki tata ngā pānga taha o te pūnaha ārai mate,
– he raruraru tonu te urunga atu me te utu o te maimoatanga i te nuinga o ngā wāhi.
Te Katinga
Kua hurihia e te rongoā ārai mate te āhua o te maimoatanga mate pukupuku mā te tuku i tētahi huarahi hou hei whakamahi i te mana o te pūnaha ārai mate . Kei roto i ēnei huarahi ko ngā aukati tirotiro, te rongoā pūtau-T CAR, ngā paturopi monoclonal, ngā kano kano mate pukupuku, te rongoā cytokine, ngā huaketo oncolytic, me ngā rongoā pūtau whāngai pērā i te TIL. He rerekē ngā painga, ngā herenga, me ngā tohu o ia huarahi. Nō reira, me whakatau ngā whakatau mō te rongoā ārai mate i roto i te kōrero tahi me te tohunga mate pukupuku, me te whakaaro ki te momo mate pukupuku, te āhua o te tūroro, me ngā tohu koiora e tika ana. Mā te rangahau tonu, e tūmanakohia ana ka whai hua ake te rongoā ārai mate, ka haumaru ake, ka whānui ake te urunga atu ki ngā tūroro mate pukupuku.
