Feline fibrosarcoma lossis sarcoma cuam tshuam nrog qhov chaw txhaj tshuaj, suav nrog ntawm 6 thiab 12% ntawm cov qog feline Nws yog cov qog mesenchymal hauv uas cov ntaub so ntswg fibroblasts proliferate. Nws yog ib tug neoplasm aggressivethiab nrog ib tug siab nyiam rau hauv zos rov tshwm sim. Lawv tshwm sim raws li ib pob me me los yog o uas loj hlob sai, txawm li cas los xij, lawv tsis feem ntau metastasize rau lwm lub cev.
feline fibrosarcoma yog dab tsi?
Fibrosarcoma is a malignant mesenchymal qog nyob rau hauv uas fibroblasts proliferate, hlwb muaj nyob rau hauv connective cov ntaub so ntswg uas tsim collagen thiab koom nyob rau hauv caws pliav. Nws yog mesenchymal vim nws yog cov qog ntawm mesenchymal keeb kwm, cov ntaub so ntswg uas tsim nyob rau hauv lub embryonic lub xeev ntawm feline thiab uas ua rau kom txhawb nqa thiab txuas cov ntaub so ntswg.
Feline fibrosarcoma muaj puab, mos, los yog khov zoo li, thiab tuaj yeem ua ib leeg lossis ntau qhov. Adhesions rau cov khaubncaws sab nraud povtseg nyob ze tshwm sim. Nws tsis yog mob qog nqaij hlav lossis nrog ulcerations, tsuas yog nyob rau theem kawg. Nws tsis tshua muaj tshwm sim rau cov metastases tshwm sim (los txog ntawm cov qog nqaij hlav qog nqaij hlav hauv lwm qhov hauv lub cev), thaum rov ua dua ntawm cov qog thaum tshem tawm yog qhov tshwm sim.
Cov tsos mob Fibrosarcoma hauv miv
Feline fibrosarcoma tuaj yeem tshwm sim thaum twg los tau. Txawm li cas los xij, nws muaj ntau dua nyob rau hauv miv nruab nrab . Thaum xub thawj, lub pob me me heev thiab pom pom thaum muab tus miv, tab sis loj hlob sai heev.
This mass may be relatively mobile and be fixed to the subcutaneous tissue and underlying musculature, with probable infiltration of surrounding structures. Qhov no ua rau qhov chaw nruab nrab ntawm cov qog thiab cov ntaub so ntswg noj qab haus huv tsis zoo. Qhov chaw inoculation feem ntau yog interscapular zone (nruab nrab ntawm tus miv lub xub pwg nyom thiab caj dab). Cov pawg loj yuav raug cuam tshuam los ntawm kev raug mob los yog mob plab.
Ntawm qhov tod tes, yog tias metastasis tshwm sim, uas feem ntau tshwm sim hauv lub ntsws, respiratory alterations..yuav tshwm.
Causes of fibrosarcoma in miv
Feem ntau, cov qog tshwm sim raws li kev hloov pauv caj ces. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv ntawm feline fibrosarcoma nws tuaj yeem tshwm sim rau cov laj thawj no:
- Vaccination: tom qab txhaj tshuaj tiv thaiv ntawm qhov chaw txhaj tshuaj. Qee cov miv tsim cov pob txha me me ntawm qhov chaw no uas ploj mus hauv ob mus rau peb lub lis piam raws li qhov tshwm sim ntawm kev txhaj tshuaj. Yog tias nws tsis ploj mus, qhov mob mob ntev tuaj yeem ua rau kev loj hlob ntawm cov qog no. Qhov mob ntawm qhov chaw txhaj tshuaj tiv thaiv kab mob no tshwm sim ntau zaus hauv cov tshuaj tiv thaiv nrog adjuvants, uas yog cov khoom siv ntxiv rau cov tshuaj tiv thaiv los txhim kho lawv cov txiaj ntsig. Cov tshuaj tiv thaiv uas feem ntau muaj adjuvants yog rau rabies thiab feline leukemia.
- External agents: Lwm cov tshuaj sab nraud hauv cov ntaub so ntswg subcutaneous, xws li microchips, lufenuron lossis tshuaj tua kab mob ntev.
- Feline sarcoma virus: Lwm qhov tsis tshua muaj tshwm sim yog tus kab mob feline sarcoma, muab los ntawm tus kab mob feline leukemia, uas ua rau muaj hom kab mob no. qog.
Feline fibrosarcoma diagnosis
Ua ntej tshaj plaws, yuav tsum tau ua ib qho abscess ntawm qhov chaw txhaj tshuaj nrog ultrasound thiab txiav txim tawm tus kab mob los ntawm feline leukemia. virus los ntawm kev sim.
Cytology yog siv me ntsis hauv kev kuaj mob, xav tau Cytology is of me me use in the diagnosis. Qhov kev kuaj ntshav no yuav tsum tau ua rau ntawm cov pob uas loj dua ob centimeters thiab rau cov uas tau tshwm sim tau peb lub hlis tom qab inoculation los yog loj hlob nyob rau hauv ib lub hlis ntawm inoculation.
Biopsy histology yuav qhia ib qho tseem ceeb inflammatory tivthaiv, nrog proliferation ntawm mononuclear hlwb, fibrosis, thiab granulation. Cov sarcomas no yog tus cwj pwm los ntawm kev ua haujlwm siab mitosis (cell division) thiab loj hauv nruab nrab necrosis (cell tuag).
Tseem X-rays yuav tsum tau noj, tshwj xeeb tshaj yog ntawm lub hauv siab, txhawm rau ntsuam xyuas seb puas muaj metastases hauv lub ntsws lossis lwm yam. qhov chaw.
Feline fibrosarcoma kho mob
Kev kho mob fibrosarcoma hauv miv yuav nyob ntawm qhov loj thiab qhov chaw ntawm cov qog thiab seb puas muaj metastasis. Ua li no, cov kev kho mob ua tau yog:
- thiab fasciae nyob ib sab ntawm lub qog, vim nws qhov muaj peev xwm infiltrative zoo. Kev phais cov npoo ntawm yam tsawg kawg yog 2 cm yuav tsum tau, qhov zoo tshaj 3-5 cm sab thiab tob rau cov qog loj, uas tej zaum yuav muaj xws li cov txheej txheem vertebral dorsal spinous thiab dorsal ciam teb ntawm scapula.
- Radiotherapy: xov tooj cua kho tau siv tau, yog thaj chaw irradiated qhov chaw uas cov qog nyob ua ntej qhov phais thiab nws yuav tsum tau ua thaum kho. tau pib, ib lub lim tiam lossis ob xyoos tom qab kev phais. Qhov ua tau zoo ntawm kev kho hluav taws xob sib txawv nyob ntawm seb qhov kev txiav tawm yav dhau los, qhov loj me ua ntej kev txiav tawm, thiab qhov zoo ntawm qhov kev txiav tawm.
- Chemotherapy: Tshuaj kho tau 50-60% siv tau carboplatin lossis doxorubicin. Feline fibrosarcomas tsis cuam tshuam nrog cov tshuaj tiv thaiv muaj cov lus teb qis dua rau kev kho mob, nyob ib ncig ntawm 10-15%.
Yog hais tias muaj metastases, aggressive phais yuav tsum tsis txhob ua.
Feline fibrosarcoma prognosis
Cov tsos mob ntawm feline fibrosarcoma yog tiv thaiv, vim muaj kev pheej hmoo ntawm rov tshwm sim dua. Txawm li cas los xij, nrog kev phais zoo, tshuaj kho mob thiab kev kho hluav taws xob, tus miv tuaj yeem nyob tau ntau xyoo.
Feline fibrosarcoma tiv thaiv
Tus kab mob no tshwm sim nyob rau hauv miv ua rau kom lawv txhaj tshuaj tiv thaiv. Txawm li cas los xij, qhov tshwm sim ntawm cov kab mob thiab lawv qhov ua rau tuag taus ntau dua qhov kev pheej hmoo ntawm kev tsim cov qog no, yog li kev txhaj tshuaj tiv thaiv yuav tsum tsis txhob tso tseg.
Txhawm rau tiv thaiv qhov nyuaj ntawm kev tshem tawm cov qog hauv thaj tsam interscapular, nws raug pom zoo txhaj tshuaj tiv thaiv miv hauv lwm qhov chaw, xws li hauv extremities los yog hauv cheeb tsam tom qab tav. Nyob rau hauv txoj kev no, yog tias cov qog no tshwm sim hauv cov cheeb tsam no, cov ceg ceg tuaj yeem raug txiav lossis tshem tawm zoo dua tuaj yeem ua tiav nrog cov npoo tsim nyog nyob rau sab.
