Yakasarudzika chipfuva brachytherapy

Brachytherapy yekenza yemazamu inosanganisira kuisa radioactive zvinhu zvakananga munzvimbo makenza yemazamu yabviswa pazamu.

Cancer maseru anowanda nekukurumidza kupfuura zvakajairika maseru mumuviri. Nekuti radiation inonyanyisa kukuvadza kumasero anokurumidza kukura, kurapwa nemwaranzi kunokanganisa maseru ekenza zviri nyore kupfuura masero akajairwa. Izvi zvinodzivirira maseru egomarara kubva mukukura nekukamurana, uye zvinotungamira mukufa kwesero.

Brachytherapy inounza kurapwa kwemwaranzi kwakananga uko uko masero ekenza mukati mezamu aripo. Zvinogona kusanganisira kuisa sosi yemwaranzi munzvimbo yekuvhiya mushure mekunge chiremba anovhiya abvisa bundu repazamu. Iyo radiation inongosvika kune diki nzvimbo yakatenderedza nzvimbo yekuvhiya. Iyo haibate iro zamu rese, ndosaka ichinzi "chidimbu chezamu" kurapwa kwemwaranzi kana chikamu chemazamu brachytherapy. Chinangwa ndechekudzora mhedzisiro yemhedzisiro kune diki vhoriyamu yemaitiro chaiwo.

Kune mhando dzakasiyana dzebrachytherapy. Kune nzira dzinosvika mbiri dzekununura radiation kubva mukati mechipfuva.

YEMAHARA BRACHYTHERAPY (IMB)

• Tsono dzinoverengeka diki dzine machubhu anonzi macatheters anoiswa kuburikidza neganda mukati mematumbu ezamu rakatenderedza nzvimbo yechiuno. Izvi zvinowanzoitwa 1 kusvika 2 mavhiki mushure mekuvhiyiwa.
• Mammography, ultrasound, kana CT scans zvinoshandiswa kuisa iyo radioactive zvinhu kwazvinogona kushanda zvakanyanya kuuraya cancer.
• Iyo radioactive zvinhu inoiswa mune iyo catheters uye inosara kwe1 vhiki.
• Dzimwe nguva mwaranzi inogona kuunzwa kaviri pazuva kwemazuva mashanu nemuchina unodzorwa kure-kure.

INTRACAVITARY BRACHYTHERAPY (IBB)

• Mushure mekubviswa kwebundu remuzamu, pane mhango apo kenza yakabviswa. Chishandiso chine bhora resilicone uye chubhu ine migero inomhanya mairi inogona kuiswa mune ino mhango. Mazuva mashoma mushure mekuiswa, radiation muchimiro chediki radioactive pellets inogona kupinda mumatanho, ichiendesa radiation kubva mukati mebharuni. Izvi zvinowanzoitwa kaviri pazuva kwemazuva mashanu. Dzimwe nguva catheter inoiswa panguva yekuvhiya kwekutanga iwe wakarara.
• Ultrasound kana CT zviyero zvinoshandiswa kutungamira kunyatsoiswa kwechinhu chine radioactive uko kuchashanda zvakanyanya kuuraya kenza ichidzivirira mativi ari pedyo.
• Iyo catheter (chibharumu) inoramba iri munzvimbo kweanenge 1 kusvika 2 mavhiki uye inobviswa kuhofisi yemupi wako. Mitsindo inogona kudikanwa kuti ivhare gomba kubva panobviswa catheter.

Brachytherapy inogona kupihwa se "yakaderera dosi" kana "yakakwira dosi."

• Avo vanogamuchira kurapwa kwakaderera-diki vanochengetwa muchipatara mukamuri yega. Radiation inoendeswa zvishoma nezvishoma pamusoro pemaawa kusvika kumazuva.
• Yepamusoro-dhizaini yekurapa inopihwa sekunze kwekushandisa muchina uri kure, zvakare kazhinji kupfuura mashanu kana mazuva akadaro. Dzimwe nguva kurapwa kunoendeswa kaviri pazuva rimwe chete, kwakaparadzaniswa nemaawa mana kusvika matanhatu pakati pezvikamu. Kurapa kwega kwega kunotora maminetsi gumi nemashanu kusvika makumi maviri.

Dzimwe nzira dzinosanganisira:

• Yekusingaperi yemazamu mbeu yekudyara (PBSI), mune iyo radioactive mbeu inoiswa yega yega kuburikidza netsono mukati mechipfuva mhango mavhiki akati wandei mushure me lumpectomy.
• Intraoperative radiation kurapwa kunoendeswa mukamuri yekuvhiyira iwe paunenge wakarara mushure mekubviswa kwemazamu. Mushonga wacho unopedzwa mune isingasviki awa. Izvi zvinoshandisa muhombe x-ray muchina mukati meimba yekushandisa.

Nyanzvi dzakadzidza kuti mamwe makenza anowanzo dzoka padyo nenzvimbo yekutanga yekuvhiya. Naizvozvo, mune dzimwe nguva, iro zamu rose rinogona kunge risingade kugamuchira radiation. Chikamu chemazamu chemvura chinongobata mamwe asi kwete ese mazamu, achitarisana nenzvimbo uko cancer ingangodzoka.

Breast brachytherapy inobatsira kudzivirira gomarara repazamu kubva pakudzoka. Iyo radiation radiation inopihwa mushure me lumpectomy kana chidimbu mastectomy. Maitiro aya anonzi adjuvant (ekuwedzera) radiation radiation nekuti iri kuwedzera kurapwa kupfuura kuvhiyiwa.

Nekuti mahunyanzvi aya haana kunyatso kufundwa seyese-yemazamu radiation kurapwa, hapana chibvumirano chakazara nezve kuti ndiani angangobatsirika.

Mhando dzekenza yemazamu iyo inogona kurapwa neparutivi radiation yemazamu inosanganisira:

• Kunyorera carcinoma in situ (DCIS)
• Kenza yemazamu inoparadza

Zvimwe zvinhu zvinogona kutungamira mukushandiswa kwebrachytherapy zvinosanganisira:

• Saizi yemamota isingasviki 2 cm kusvika 3 cm (inenge inch)
• Hapana humbowo hwebundu pamwe chete nemicheto yemota yebvunzo yakabviswa
• Lymph node haina kunaka kune bundu, kana imwe chete node ine zvidiki zvidiki

Udza mupiki wako kuti ndeapi mishonga yauri kutora.

Pfeka mbatya dzakasununguka kumishonga.

Radiation therapy inogona zvakare kukuvadza kana kuuraya maseru ane hutano. Kufa kwemasero ane hutano kunogona kutungamira kumhedzisiro. Iyi mhedzisiro inoenderana nedosi yemwaranzi, uye kangani uine kurapwa.

• Unogona kunge uine kudziya kana kushushikana kwakakomberedza saiti yekuvhiya.
• Iwe unogona kukura kutsvuka, unyoro, kana kunyangwe hutachiona.
• Homwe yemvura (seroma) inogona kukura munzvimbo yekuvhiya uye ingangoda kudhonzwa.
• Ganda rako pamusoro penzvimbo inorapwa rinogona kushanduka rakatsvuka kana rakasviba muvara, peel, kana kuvava.

Yenguva-refu mhedzisiro mhedzisiro inogona kusanganisira:

• Kuderedza kukura kwemazamu
• Kuwedzera kusimba kwezamu kana imwe asymmetry
• Ganda kutsvuka uye kushanduka

Pakave pasina hutsva hwemhando yepamusoro uchienzanisa brachytherapy kune yakazara mazamu radiation. Nekudaro, zvimwe zvidzidzo zvakaratidza mhedzisiro kuva yakafanana kune vakadzi vane kenza yemazamu inowanikwa munharaunda
