Tiyeni tiphunzire za khansa ya m'magazi yotchedwa CML (Chronic Myeloid Leukemia) mwachidule.

Ambiri aife timaopa mawu oti "khansa." Ndi chinthu chofala kwambiri. Koma masiku ano, chifukwa sayansi ya zamankhwala yapita patsogolo kwambiri, zakhala zotheka kukhala ndi mitundu ina ya khansa. Lero, tikambirana za mtundu umodzi wa khansa yamagazi. Ndi CML, yomwe imayimira Chronic Myeloid Leukemia. Mwina munamvapo dzinali mutayesedwa magazi nthawi zonse. Chifukwa chake, tiyeni tikambirane mwatsatanetsatane popanda mantha.

Chabwino, ndiye CML iyi ndi chiyani?

Mwachidule, CML ndi khansa ya m'magazi mwathu. Imayamba m'mafupa mkati mwa mafupa athu. Mafupa ali ngati fakitale yomwe imapanga mitundu ya maselo omwe thupi lathu limafunikira otchedwa maselo ofiira a magazi, maselo oyera a magazi, ndi ma platelet. Mu CML, china chake chimalakwika ndi maselo oyambira a myeloid m'maselo a mafupa awa, ndipo amayamba kugawikana ndikuchulukana mosalamulirika.

Izi zimatchedwanso `chronic myelogenous leukemia` kapena `chronic granulocytic leukemia`.

Koma nkhani yofunika kwambiri komanso yabwino kwambiri apa ndi yakuti ndi mankhwala apamwamba amakono, anthu ambiri omwe ali ndi CML amatha kukhala ndi moyo wabwinobwino . Izi zikutanthauza kuti m'malo mokhala matenda oopsa, akhala matenda osatha omwe angathe kuthetsedwa ndi mankhwala.

Kodi CML iyi ikupita patsogolo mofulumira bwanji?

Mawu akuti "chronic" amatanthauza "kwanthawi yayitali." Ndipo umu ndi momwe matendawa alili. CML ndi matenda ofala kwambiri. Nthawi zina imatha kukhalapo kwa zaka zambiri popanda zizindikiro zilizonse. Anthu ambiri amapeza kuti ali nayo mwangozi, pamene mayeso a magazi omwe amachitika pazifukwa zina akuwonetsa kusakhazikika kwa kuchuluka kwa maselo m'magazi mwawo.

Koma ngati sichinalandire chithandizo, vutoli likhoza kukhala loopsa patatha zaka zitatu kapena zinayi. Chifukwa chake, ndikofunikira kwambiri kuzindikira matendawa ndikuyamba kulandira chithandizo msanga.

Kodi ndi zizindikiro ziti zomwe munthu amene ali ndi CML angakumane nazo?

Kawirikawiri, sipangakhale zizindikiro zazikulu kumayambiriro. Komabe, pali zizindikiro zina zomwe zimawonekera pakapita nthawi. Izi nthawi zambiri ndi zinthu zomwe timaganiza kuti ndi zachilendo ndipo timazinyalanyaza.

N’chifukwa chiyani CML imayamba? Kodi ndi yobadwa nayo?

Funso ili ndi lomwe anthu ambiri ali nalo. Chofunika kwambiri kumvetsetsa apa ndichakuti matenda a CML si matenda obadwa nawo . Izi zikutanthauza kuti ana sakudwala chifukwa chakuti makolo awo anali nawo. Ndipo si matenda obadwa nawo.

Chabwino, tsopano tiyeni tiwone momwe izi zimagwirira ntchito. Mwachidule, zili motere:

1. Kusintha kumachitika m'majini a maselo athu oyambira, ndipo jini yatsopano, yowonjezera yotchedwa `BCR-ABL` imapangidwa.

2. This new gene gives new instructions to stem cells to make an unusual form of an enzyme called `tyrosine kinase`.

3. Ganizirani za ma enzyme awa ngati ma switch a "oyatsa" ndi "ozimitsa" pa nyali. Izi ndi zomwe zimalamulira kugawa kwa maselo.

4. Koma enzyme ya `tyrosine kinase` yopangidwa modabwitsayo ilibe chosinthira "chozimitsa". Nthawi zonse imakhala "yoyatsa".

5. Popeza palibe chosinthira cha "ozimitsa", maselo oyambira m'mafupa amapitiliza kulandira zizindikiro zogawa, kugawa, ndi kuchulukana mosalamulirika.

6. Zotsatira zake, maselo ambiri oyera osakhwima m'magazi (omwe amatchedwanso `blasts`) amayamba kupangika.

7. Pakapita nthawi, maselo osazolowereka amenewa amadzaza mafuta a m'mafupa. Kenako mafuta a m'mafupa amataya mphamvu zake zopangira maselo ofiira athanzi, maselo oyera a m'magazi, ndi ma platelet. Zotsatira zake, zizindikiro zomwe tatchulazi zimayamba kuonekera.

Zoopsa ndi zovuta zomwe zingachitike chifukwa cha izi

Zinthu zoopsa

Chinthu chokhacho chodziwika bwino chomwe chimayambitsa matenda a CML ndi kupezeka kwa mphamvu ya kuwala kwambiri . Komabe, izi sizichitika kawirikawiri. Mphamvu ya kuwala komwe timakumana nako m'moyo wabwinobwino (monga kutenga X-ray) siimayambitsa izi.

Zovuta zomwe zingatheke

CML ingayambitse mavuto awiri akuluakulu:

• Kuchepa kwa magazi m'thupi: Kuchepa kwa kupanga maselo ofiira a magazi abwinobwino, zomwe zimachepetsa kuchuluka kwa mpweya womwe thupi limafunikira, zomwe zimapangitsa kutopa ndi kufiira.
• Splenomegaly: Maselo ambiri osazolowereka m'magazi amasonkhana mu ndulu, zomwe zimapangitsa kuti itukuke. Izi zingayambitse kusasangalala m'mimba komanso kumva kukhuta ngakhale mutadya pang'ono.

Kuphatikiza apo, kafukufuku wina wasonyeza kuti anthu omwe ali ndi CML akhoza kukhala ndi chiopsezo chowonjezeka pang'ono chotenga mitundu ina ya khansa (khansa yachiwiri).

Kodi madokotala amazindikira bwanji CML?

Dokotala wanu angakayikire izi poyesa magazi mosavuta. Komabe, kuti atsimikizire matendawa, pamafunika mayeso apadera omwe amafufuza kusintha kwa majini.

Kodi magawo a CML ndi ati?

Mosiyana ndi khansa zina, CML siili m'gulu la "magawo 1, 2, 3, 4." M'malo mwake, imayikidwa m'gulu la "magawo." Izi zimatsimikiziridwa ndi kuchuluka kwa maselo oyera amagazi osakhwima ('blasts') m'magazi ndi m'mafupa.

• Gawo Losatha: Ili ndi gawo loyambirira. Pali maselo ochepera 10% a 'blasts' m'magazi ndi m'mafupa. 80-90% ya anthu omwe amapezeka ndi CML ali pagawoli. Anthuwa akhoza kukhala ndi zizindikiro kapena ayi.
• Gawo Lofulumira: Mu gawoli, chiwerengero cha maselo 'ophulika' chimawonjezeka kufika pakati pa 10% ndi 19%. Zizindikiro zimayamba kuonekera bwino.
• Gawo Lophulika kapena Vuto la Kuphulika: Ili ndi gawo loopsa kwambiri komanso loopsa kwambiri. Chiwerengero cha maselo a `kuphulika` chimawonjezeka ndi 20% kapena kuposerapo. Zizindikiro monga kutopa kwambiri, kutentha thupi, ndi kuchepa thupi zimakhala zovuta kwambiri.
• CML Yosagonja: Ili ndi dzina lomwe limaperekedwa kwa CML yomwe siyankha chithandizo kapena yomwe imabwereranso pambuyo pa chithandizo.

Kodi mankhwala a CML ndi ati?

Apa ndi pomwe nkhani yabwino yokhudza CML imabwera. Masiku ano, pali mankhwala othandiza kwambiri a matendawa.

Chithandizo chachikulu ndi mtundu wa mankhwala otchedwa Tyrosine Kinase Inhibitors (TKIs) . Awa ndi mankhwala omwe amatengedwa ngati mapiritsi.

Mukukumbukira enzyme yachilendo yomwe tidakambirana kale yomwe imagwira ntchito ngati switch "yoyatsa"? Ndicho chimene mankhwala awa amachifuna. Zimene ma TKI amachita ndikuletsa enzyme yomwe ilibe switch "yoyatsa" kugwira ntchito. Amailetsa. Kenako maselo a CML omwe amagawanitsa mosalamulirika sapeza chizindikiro chogawanitsa, ndipo pakapita kanthawi maselo amenewo amafa.

Mankhwala a TKI awa asintha kwambiri miyoyo ya odwala a CML. Mankhwalawa asanafike, pafupifupi 20% yokha ya anthu omwe adapezeka ndi CML ndi omwe adapulumuka kwa zaka 5. Koma lero, ndi ma TKI, chiwerengero chimenecho chawonjezeka kufika pa 90%.

Mankhwalawa nthawi zambiri amamwedwa moyo wonse. Mitundu ina ya ma TKI yomwe imagwiritsidwa ntchito kwambiri ndi iyi:

• Imatinib
• Dasatinib
• Nilotinib
• Bosutinib
• Ponatinib

Kodi ma TKI ali ndi zotsatirapo zoyipa?

Inde, monga mankhwala ena aliwonse, pakhoza kukhala zotsatirapo zake. Koma nthawi zambiri zimatha kuthandizidwa. Zofala kwambiri ndi izi:

• Kuwawa kwam'mimba
• Kutopa
• Kutsegula m'mimba
• Kugwedeza minofu
• Kutupa
• Nthawi zina, zinthu monga kuwonongeka kwa chiwindi ndi kuchepa kwa maselo amagazi zimatha kuchitika.

Dokotala wanu adzakulangizani za zotsatirapo izi ndikuthandizani kuzithetsa.

Kodi CML imatha kuchiritsidwa kwathunthu?

Pakadali pano, njira yokhayo "yochiritsira" CML ndi kuyika maselo oyambira a allogeneic . Izi zimaphatikizapo kuyika maselo oyambira kuchokera kwa munthu wathanzi kupita kwa wodwalayo. Komabe, iyi ndi njira yovuta kwambiri komanso yowopsa. Chifukwa chake, nthawi zambiri imachitika kwa odwala omwe sayankha ku matenda a TKI.

Kodi kukhala ndi CML kumakhala bwanji ndipo chiyembekezo chili bwanji?

Pamene CML yayamba kuchira ndi chithandizo, simudzakhalanso ndi zizindikiro ndipo palibe zizindikiro za matendawa zomwe zingaonekere pa mayeso. Izi zikutanthauza kuti mutha kukhala moyo wabwinobwino. Koma muyenera kupitiriza kumwa mankhwala oletsa matendawa. Muyeneranso kuonana ndi dokotala wanu nthawi zonse kuti akayesedwe magazi kuti muwone ngati chithandizo chanu chikugwira ntchito bwino.

Kukhululukidwa Kopanda Chithandizo (TFR)

Ichi ndi chitukuko chaposachedwa komanso chodalirika kwambiri pa chithandizo cha CML. Izi zikutanthauza kuti odwala ena omwe akhala akumwa mankhwala a TKI kwa kanthawi ndipo matenda awo akhala akuwongoleredwa bwino tsopano akhoza kusiya kumwa mankhwalawo motsogozedwa ndi dokotala wawo. Ngakhale atasiya kumwa mankhwalawo, matendawa sanabwererenso. Koma izi sizingatheke kwa aliyense. Muyenera kukwaniritsa ziyeneretso zinazake.

Mafunso ofunikira oti mufunse dokotala wanu

Mukazindikira kuti muli ndi CML, ndi zachilendo kukhala ndi mafunso ambiri m'maganizo mwanu. Musachite mantha, funsani dokotala wanu za zinthu izi.

• Kodi ndili ndi gawo liti la CML?
• Kodi ndi njira ziti zochiritsira zomwe ndili nazo?
• Kodi ndidzamva bwanji panthawi ya chithandizo? Kodi zotsatira zake ndi ziti?
• Kodi ndingapitirize ntchito yanga pamene ndikulandira chithandizo?
• Kodi ndiyenera kuyezetsa magazi kangati kuti ndione ngati chithandizocho chayenda bwino?
• Kodi pali mwayi wotani woti matenda anga atha?
• Kodi kuyika maselo oyambira m'thupi n'koyenera matenda anga?
• Kodi ndi ndani amene ndingalankhule naye pankhani yosamalira ndalama zothandizira?
