I-Sarcoma bone

I-bark sarcoma (i-Ewing's sarcoma) yisifo esibi esiya emathanjeni amathambo omuntu. Kungatholakala endaweni yamathambo wesiguli, kodwa ngokuvamile lesi sifo sithinta amathambo we-tubular eside, futhi ama-metastases aphindaphindiwe avela kaningi kuma-vertebrae, izimbambo namathambo e-pelvic. Amathambo eSarcoma ahlaziya futhi abelethe isifuba, isisu, umaphaphu noma isifo sezinso.

Izimbangela nezimpawu ze-sarcoma yamathambo

Izizathu zokuthuthukiswa kwe-sarcoma yamathambo azange zifundwe ngokwanele. Izinto ezibangela ukubonakala kwalolu hlobo lwezicubu zihlanganisa:

• i-cartilaginous exostoses;
• i-fractures;
• i-radiation ionizing;
• Isifo sikaPaget;
• ezinye izinhlobo zomdlavuza.

Esikhathini sokuqala sokuthuthukiswa kwalesi sifo, azikho izimpawu. Ngemuva kokuba isisu siqala ukwandisa usayizi, izimpawu ezifana ne-sarcoma of bone zivela:

• ukuguqulwa kwesithambo;
• ukuvinjelwa kokuhamba ngokuhlanganyela, okuphambene nesisu;
• ubuhlungu obukhulu kakhulu ebusuku;
• umkhuhlane.

Isithombe sesitholampilo sibonakala ngesikhumba sendawo yesikhumba. Uma isiguli sinesifo sarcoma, kunezibonakaliso zesifo, njengokungasebenzi kahle kwezitho zomzimba nezinduna.

Ukwelashwa kwe-bone sarcoma

Indlela eholela ekutholeni i-sarcoma ye-osteogenic ye-femal, i-hummer kanye nanoma yimuphi elinye ithambo lokutadisha i-x-ray. Ukuxilongwa kokugcina kusekwe ngokusekelwe emiphumeleni yokufundwa komzimba we-fragment encane, etholakala yi-biopsy.

Ngemva kokuthola lesi sifo, ngokushesha uqale ukwelashwa. Isibikezelo esihle se-sarcoma yethambo singanikezwa kuphela emva kokusebenza kanye nezifundo eziningana ze-chemotherapy. Lokhu kubangelwa ukuthi lesi sifo sinomkhuhlane ophakeme kakhulu we-metastasis enegazi elimangalisayo.

Ukungenelela kwegciwane lokugulisa umzimba kuyisici esiyinhloko sokwelashwa kwe-bone sarcoma yengalo, umlenze, i-hip. Ukungafani kokusebenza okunjalo yilokhu:

• umonakalo omkhulu kumzimba wesisindo;
• ukubandakanyeka kwinqubo yomdlavuza yesikhwama senhliziyo;
• izifo ezinamahloni ezinobuthi noma ukutheleleka kwezicubu.

Uma lesi sifo sesifinyelele kakhulu ngokweqile noma ukubola kwayo kubonakala ngokudakwa nokuphuza igazi, kusetshenziselwa ukusebenza okunamandla: ukuchithwa nokukhipha.

Ukwelashwa kwe-radiar for sarcoma ye-humeral, wesifazane kanye namanye amathambo asetshenziselwa lapho kungenakwenzeka ukususa isisu noma i-metastases. I-Chemotherapy kumele isetshenziswe ngaphambi kokuhlinzwa. Lokhu kukuvumela ukuba unciphise ngokushesha ubukhulu bokubunjwa kwe-tumor futhi ususe ama-micrometastases. Ngaphezu kwalokho, izinqubo ezinjalo zisiza ukuthi unqume ukuthi i-tumor ibucayi yini ezidakamizwa ezihlukahlukene futhi ukhethe umuthi wokwelapha okufanelekile ngemuva kokuqedela ukusebenza.

I-postotheative chemotherapy iyadingeka ukuze igweme ukukhula nokubhujiswa okuphelele kwe-metastase ezincane. Ibuye isetshenziselwe ukuphatha izidakamizwa ezide ezivele zithuthukile. Ngokuvamile kuyadingeka ukuba usebenzise izifundo ezingu-4-10 ngenhlanganisela yemithi efana nalokhu:

• I-Doxorubicin;
• Ifosfamide;
• UVincristine;
• Dactinomycin;
• Etoposide;
• Cyclophosphamide.

Ukuqaphela emva kokwelashwa kwe-bone sarcoma

Ngemuva kokuphelelwa ukwelashwa okusezingeni eliphezulu Ukuhlolwa kwe-sarcoma ku-oncologist kufanele kwenziwe iminyaka emibili njalo ezinyangeni ezintathu, ngonyaka we-3 njalo ezinyangeni ezine nangonyaka we-4 no-5 njalo ezinyangeni eziyisithupha. Ngemva kokususwa kwe-sarcoma ephansi, ukulandelwa kufanele kwenziwe njalo ezinyangeni ezingu-6 iminyaka emibili. Ucwaningo olunjalo lubandakanya:

• i-radiography noma i-CT yazo zonke izitho zomzimba;
• I-MRI / CT ye-bone, eyathinteka yi-tumor;
• I-Ultrasound yesigxobo sesisu .
