Leukemia caruurnimada iyo daawadeeda

Leukemia caruurnimada

Leukemia waa kansarka ugu badan ee ku dhaca carruurta iyo da'yarta, taasoo ka dhigan ku dhawaad ​​1 ka mid ah 3dii kansar. Inta badan leukemias carruurnimada waa lymphocytic leukemia ba'an (ALL) iyo acute myeloid leukemia (AML). Leukemias dabadheeraad ah ayaa ku yar carruurta.

Cudurka 'myeloid leukemia' ee ba'an ee carruurta

AML (acute myeloid leukaemia) is a blood and bone marrow malignancy that affects children. AML, also known as acute myelogenous leukaemia or acute nonlymphocytic leukaemia, is a kind of leukaemia that affects the blood cells. Acute cancers usually progress swiftly if they are not treated. Chronic cancers typically worsen over time. Myeloid stem cells in AML normally grow into myeloblasts, a type of immature white blood cell (or myeloid blasts). In AML, the aberrant myeloblasts, or leukaemia cells, do not mature into healthy white blood cells. Leukemia cells can accumulate in the blood and bone marrow, making it difficult for healthy white blood cells, red blood cells, and platelets to thrive. Infection, anaemia, and simple bleeding are all possible outcomes. Outside of the blood, leukaemia cells can travel to other regions of the body, such as the central nervous system (brain and spinal cord), skin, and gums. Leukemia cells can sometimes produce a solid tumour termed a myeloid sarcoma. Granulocytic sarcoma, or chloroma, is another name for myeloid sarcoma.

Daawaynta ba'an ee myeloid leukemia

Chemotherapy ee carruurta badankooda qaba cudurka leukemia myeloid ba'an (AML) waxaa loo kala saaraa laba weji:

• Induction
• Isku-darka (xoojinta)

Carruurta qaba AML waa in lagu daweeyaa xarumaha kansarka ama isbitaallada khibrad u leh cudurkan iyadoo ay ugu wacan tahay xoogga daawaynta iyo cawaaqib xumada ka dhalan karta.

Induction kiimoterabi ee bukaanka AML

Daunorubicin (daunomycin) iyo cytarabine (ara-C), labadoodaba waxaa la maamulaa dhowr maalmood oo isku xigta, waa daawooyinka kiimikaad ee inta badan la isticmaalo si loogu daweeyo AML. Iyada oo ku xidhan hadba inta ay dhakhaatiirtu rabaan in daawadu ay noqoto, habka daawaynta waxa lagu soo celin karaa 10 maalmood ama 2 toddobaad gudahood. Muddada daawaynta gaaban ayaa laga yaabaa inay si hufan u cirib tirto unugyada leukemia, laakiin waxay sidoo kale keeni karaan saameyn xun oo aad u daran. As part of their induction treatment, some children with AML may get a dose of the targeted medication gemtuzumab ozogamicin (Mylotarg) in addition to chemo. If the doctors believe the leukaemia will not react to just two chemo medications, they may add another chemo agent like etoposide or 6-thioguanine to the mix. This group includes children who have a high number of white blood cells or whose leukaemia cells have particular genetic defects. The chemo medicines are given again and again until the bone marrow reveals no more leukaemia cells. This usually happens after two or three therapy cycles. Most children with AML will also get intrathecal chemotherapy (chemotherapy delivered directly into the cerebrospinal fluid, or CSF) to help prevent leukaemia from relapsing in the brain or spinal cord. The use of brain radiation therapy is becoming less common. After induction therapy, between 85 percent to 90 percent of children with AML go into remission. This indicates that no symptoms of leukaemia have been identified using normal lab tests, but it does not necessarily imply that the leukaemia has been healed.

xoojinta

After the induction phase, the consolidation (intensification) phase begins. The goal is to use a more aggressive treatment to kill any remaining leukaemia cells. Some youngsters have a sibling who would be a suitable stem cell donor. Once the leukaemia is in remission, a stem cell transplant may be advised for these children, especially if the AML has some unfavourable prognostic markers. Most studies have shown that while this improves long-term survival over chemotherapy alone, it also increases the risk of significant consequences. Some clinicians may propose only delivering aggressive chemotherapy to youngsters with good prognostic criteria, and saving the stem cell transplant until if the AML relapses. Consolidation consists of heavy doses of the chemo medication cytarabine (ara-C) for most children who do not have a good stem cell donor. It’s also possible to use daunorubicin. It is normally given for a period of at least a few months. If the targeted medicine gemtuzumab ozogamicin (Mylotarg) was given during induction, it will almost certainly be given again during this stage of treatment. For as long as intensification continues, intrathecal chemo (into the CSF) is normally given every 1 to 2 months. Children with AML do not require maintenance chemotherapy (other than those with APL). Supportive care is a key element of AML treatment (proper nursing care, nutritional support, antibiotics, and blood transfusions). The aggressive therapy for AML frequently destroys much of the bone marrow, resulting in significant blood cell shortages, as well as other catastrophic consequences. The current high remission rates would not be conceivable without antibiotic treatment of infections or transfusion assistance.

Leukemia ba'an ee caruurnimada (ALL)

Acute lymphoblastic leukaemia in children (also known as ALL or acute lymphocytic leukaemia) is a blood and bone marrow malignancy. If left untreated, this type of cancer usually worsens swiftly. Too many stem cells turn into lymphoblasts, B lymphocytes, or T lymphocytes in a child with ALL. Leukemia cells are another name for these cells. These leukaemia cells do not function like normal lymphocytes and are unable to effectively fight infection. In addition, when the number of leukaemia cells in the blood and bone marrow rises, there is less room in the blood and bone marrow for healthy white blood cells, red blood cells, and platelets. Infection, anaemia, and simple bleeding are all possible outcomes.

Daawaynta lymfoblastic leukemia ba'an ee caruurnimada

Carruurta qabta leukemia ba'an ee lymphoblastic waxaa laga yaabaa inay helaan daawayn kala duwan (Dhammaan). Daawooyinka qaar waa kuwo caadi ah (horeyba waa loo isticmaalay), halka kuwa kalena ay marayaan baaritaan caafimaad. Tijaabada caafimaad ee daawaynta waa daraasad cilmi baaris oo ujeedadeedu tahay in lagu caawiyo bukaanada qaba kansarku inay horumariyaan daawadooda hadda jirta ama ay wax badan ka bartaan daawaynta suurtagalka ah. Marka daraasaadka caafimaadku caddeeyaan in daawaynta cusub ay ka sarreyso heerka hadda la joogo, daawaynta cusub waxa loo qaadan karaa heerka caadiga ah.

Chemotherapy is a cancer treatment that involves administering chemicals to cancer cells in order to limit their growth, either by killing them or preventing them from growing. Chemotherapy medications enter the bloodstream and can reach cancer cells all throughout the body when taken by mouth or injected into a vein or muscle (systemic chemotherapy). Chemotherapy that is administered directly into the cerebrospinal fluid (intrathecal), an organ, or a bodily cavity such as the abdomen targets cancer cells primarily in specific regions (regional chemotherapy). Combination chemotherapy is a type of cancer treatment that involves the use of multiple anticancer drugs. The method of chemotherapy administration is determined by the child’s risk group. Anticancer medications are given in higher doses to children with high-risk ALL than to those with standard-risk ALL. Childhood ALL that has spread or may spread to the brain and spinal cord is treated with intrathecal chemotherapy.

Daaweynta shucaaca ee DHAMMAAN

Daaweynta shucaaca waa daawaynta kansarka taas oo ku lug leh isticmaalka tamarta sare raajada or other forms of radiation to kill or stop cancer cells from developing. External radiation therapy involves sending radiation from a machine outside the body to the cancerous spot. Childhood ALL taas oo u gudubtay maskaxda, xudunta laf dhabarta, ama xiniinyaha waxaa lagu daweyn karaa daawaynta shucaaca dibadda. Waxa kale oo suurtagal ah in la isticmaalo si loogu diyaariyo dhuuxa lafta beddelka unugyada tarma.

Chemotherapy oo leh unug-tallaal

Chemotherapy is a treatment that is used to kill cancer cells. Total-body irradiation is used in conjunction with chemotherapy in children aged 3 and up. The cancer treatment also kills healthy cells, including blood-forming cells. A stem cell transplant is a procedure that replaces blood-forming cells in the body. Stem cells (immature blood cells) are extracted from a donor’s blood or bone marrow, frozen, and stored. The stored stem cells are thawed and delivered to the patient via an infusion after the patient has completed chemotherapy and radiation therapy. These stem cells develop into (and replenish) blood cells in the body. For children and adolescents with ALL, stem cell transplantation is rarely used as a first-line treatment. It’s being utilized increasingly frequently as part of relapse treatment for ALL.

Daaweynta Targeted

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation therapy do. There are different types of targeted therapy: Tyrosine kinase inhibitor (TKIs) therapy: This treatment blocks the enzyme, tyrosine kinase, that causes stem cells to develop into more white blood cells than the body needs. Imatinib mesylate and dasatinib are TKIs used in the treatment of children with Philadelphia chromosome–positive ALL. Ruxolitinib is a TKI that is being studied in the treatment of newly diagnosed high-risk ALL. Monoclonal antibodies: Monoclonal antibodies are immune system proteins made in the laboratory to treat many diseases, including cancer. As a cancer treatment, these antibodies can attach to a specific target on cancer cells or other cells that may help cancer cells grow. The antibodies are then able to kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Blinatumomab and inotuzumab are monoclonal antibodies being studied in the treatment of refractory childhood ALL. Blinatumomab is also being studied in the treatment of standard-risk ALL.

Daaweynta T-Cell-ka Baabuurka

Nidaamka difaaca waxa loo isticmaalaa in lagula dagaalamo kansarka Daaweynta unugyada CAR T, hab cusub oo aasaasi ah oo lagu daaweeyo Ba'an Lymphoblastic Leukemia (ALL). Daawayntan, unugyada T waxaa laga soo qaadaa dhiigga bukaanka waxaana loo beddelaa hidde ahaan si ay u soo saaraan reseptors-ka antigen-ka (CARs). CAR-yadani waxay caawiyaan unugyada T inay helaan oo weeraraan unugyada kansarka kuwaas oo leh calaamado dusha sare ah oo gaar ah. Marka dib loogu celiyo jidhka bukaanka, unugyadan T-da ee la farsameeyay way koraan oo si sax ah u weeraraan unugyada kansarka, taas oo inta badan keenta cafis. Daaweynta unugyada CAR T waxay leedahay karti badan, laakiin waxay yeelan kartaa dhibaatooyin sida cytokine release syndrome iyo neurotoxicity. Tani waxay muujinaysaa sida ay muhiimka u tahay in la sii wado cilmi-baadhista iyo hagaajinteeda.

Kiisaska leukemia ee carruurta ma loo wareejin karaa walaalo kale?

Dhallinta qaarkood waxay leeyihiin walaalo noqon kara ku-deeqaha unugga stem. Marka uu leukemia-gu soo baxo, ku-tallaalidda unugyada asliga ah ayaa laga yaabaa in lagula taliyo carruurtan, gaar ahaan haddii AML ay leedahay calaamado saadaaliya oo aan fiicnayn. Daraasadaha intooda badani waxay muujiyeen in iyada oo tani ay hagaajinayso badbaadada muddada dheer ee daaweynta kemotherabi oo keliya, waxay sidoo kale kordhisaa khatarta ah cawaaqibka weyn. Dhakhaatiirta qaarkood ayaa laga yaabaa inay soo jeediyaan oo kaliya in la siiyo daweynta kemotherabi da'da yar ee leh shuruudo saadaal wanaagsan, iyo badbaadinta xubinta taranka unugyada asliga ah ilaa haddii AML uu soo noqdo.
