Brachytherapy ea matsoele e arohaneng

Brachytherapy bakeng sa mofetše oa matsoele e kenyelletsa ho beha lisebelisoa tse nang le mahlaseli a kotsi ka kotloloho sebakeng seo kankere ea matsoele e tlositsoeng ho sona.

Lisele tsa mofetše li ikatisa ka potlako ho feta lisele tse tloaelehileng 'meleng. Hobane radiation e kotsi haholo ho lisele tse holang kapele, kalafo ea radiation e senya lisele tsa mofetše habonolo ho feta lisele tse tloaelehileng. Sena se thibela lisele tsa mofets'e ho hola le ho ikarola, mme se lebisa lefung la sele.

Brachytherapy e fana ka kalafo ea radiation ka kotloloho moo lisele tsa mofets'e kahare ho letsoele li leng teng. Ho ka kenyelletsa ho beha mohloli o nang le mahlaseli a kotsi sebakeng sa ho buoa kamora hore ngaka e buoang e tlose hlama ea letsoele. Mahlaseli ana a fihla feela sebakeng se senyenyane ho potoloha sebaka sa ho buoa. Ha e phekole letsoele lohle, ke ka lebaka leo e bitsoang kalafo ea radiation ea "matsoele a sa fellang" kapa brachytherapy ea letsoele. Morero ke ho fokotsa litla-morao tsa mahlaseli a kotsi ho ea ho molumo o monyane oa lisele tse tloaelehileng.

Ho na le mefuta e fapaneng ea brachytherapy. Bonyane ho na le mekhoa e 'meli ea ho tsamaisa mahlaseli a tsoang ka har'a sefuba.

BRACHYTHERAPY EA SECHABA (IMB)

• Linalana tse 'maloa tse nyane tse nang le methapo e bitsoang li-catheters li beoa letlalong ka har'a lisele tsa sefuba ho potoloha sebaka sa lumpectomy. Hangata sena se etsoa libeke tse 1 ho isa ho tse 2 kamora ho buuoa.
• Mammography, ultrasound, kapa CT scans li sebelisetsoa ho beha mahlaseli a kotsi moo a tla sebetsa hantle ho bolaea mofets'e.
• Lisebelisoa tsa mahlaseli a kotsi li beoa ka har'a li-catheters 'me li sala beke e le' ngoe.
• Ka linako tse ling mahlaseli a kotsi a ka tsamaisoa habeli ka letsatsi matsatsi a 5 ke mochini o laoloang ka hole.

INTRACAVITARY BRACHYTHERAPY (IBB)

• Kamora ho tlosoa hlama ea matsoele, ho na le sekoti moo mofets'e o tlositsoeng. Sesebelisoa se nang le balune le phaephe ea silicone e nang le liteishene tse fetang ho eona e ka kenngoa kahare ena. Matsatsi a 'maloa kamora ho beoa, mahlaseli a mofuta oa li-pellets tse nyane tse ntšang mahlaseli a kotsi a ka kena liteisheneng, a fana ka radiation ho tsoa ka har'a balune. Hangata sena se etsoa makhetlo a mabeli ka letsatsi matsatsi a mahlano. Ka linako tse ling catheter e beoa nakong ea ts'ebetso ea pele ha u ntse u robetse.
• Lisebelisoa tsa Ultrasound kapa CT li sebelisetsoa ho tataisa hantle hore na lisebelisoa tse nang le mahlaseli a kotsi li beoa kae moo e tla sebetsa hantle ho bolaea mofets'e ha e ntse e sireletsa lisele tse haufi.
• Catheter (balune) e lula sebakeng sa libeke tse ka bang 1 ho isa ho tse 2 mme e tlosoa ofising ea mofani oa thepa ea hau. Ho ka hlokahala litokiso ho koala sekoti moo catheter e tlosoang teng.

Brachytherapy e ka fuoa "lethal dose e tlase" kapa "lethal dose e phahameng."

• Ba fumanang kalafo e tlase ba bolokiloe sepetlele ka phapusing ea motho ka mong. Mahlaseli a kotsi a tsamaisoa butle ho feta lihora ho isa matsatsing.
• Kalafo ea litekanyetso tse phahameng e fanoa joalo ka mokuli ea kantle ho mochini o sebelisang mochini o hole, hangata hangata ho feta matsatsi a mahlano kapa ho feta. Ka linako tse ling kalafo e fanoa makhetlo a mabeli ka letsatsi le le leng, e arotsoe ke lihora tse 4 ho isa ho tse 6 lipakeng tsa linako. Kalafo ka 'ngoe e nka metsotso e ka bang 15 ho isa ho e 20.

Mekhoa e meng e kenyelletsa:

• Ho kenya peo ea matsoele e sa feleng (PBSI), moo peo e ntšang mahlaseli a kotsi e kenngoang ka bonngoe ka nale ka mpeng ea matsoele libeke tse 'maloa kamora lumpectomy.
• Phekolo ea radiation ea opereishene e fanoa ka kamoreng ea tšebetso ha u ntse u robetse kamora ho tlosoa lisele tsa matsoele. Kalafo e phetheloa ka nako e ka tlase ho hora. Sena se sebelisa mochini o moholo oa x-ray kahare ho kamore ea tšebetso.

Litsebi li ithutile hore mefuta e meng ea mofetše e kanna ea khutla haufi le sebaka sa pele sa ho buoa. Ka hona, maemong a mang, letsoele lohle le kanna la se hloke ho amohela radiation. Ho hlaseloa ha matsoele ka nakoana ho phekola matsoele a mang feela empa eseng kaofela, ho shebile sebaka seo mofets'e o ka khutlelang ho sona haholo.

Brachytherapy ea matsoele e thusa ho thibela mofetše oa matsoele ho khutla. Phekolo ea radiation e fanoa kamora lumpectomy kapa mastectomy e sa fellang. Mokhoa ona o bitsoa adjuvant (tlatsetso) kalafo ea radiation hobane e eketsa kalafo ho feta ts'ebetso.

Hobane mekhoa ena ha e rutoe hantle joalo ka kalafo ea mahlaseli a matsoele a matsoele, ha ho lumellanoe ka botlalo hore na ke mang ea ka bang molemo.

Mefuta ea kankere ea matsoele e ka alafshoang ka mahlaseli a matsoele a matsoele a kenyelletsa:

• Ductal carcinoma in situ (DCIS)
• Kankere ea matsoele e hlaselang

Lintlha tse ling tse ka lebisang ts'ebelisong ea brachytherapy li kenyelletsa:

• Boima ba hlahala bo ka tlase ho cm 2 ho isa ho 3 cm (e ka bang lisenthimithara)
• Ha ho na bopaki ba hlahala meleng ea maqhubu a hlahala bo tlositsoeng
• Lymph node ha li na bothata bakeng sa hlahala, kapa node e le 'ngoe feela e na le likhahla tse nyane haholo

Bolella mofani oa hau meriana eo u e sebelisang.

Apara liaparo tse u tlamellang liphekolong.

Phekolo ea radiation e ka senya kapa ea bolaea lisele tse phetseng hantle. Lefu la lisele tse phetseng hantle le ka lebisa litlamorao. Litla-morao tsena li ipapisitse le tekanyo ea radiation, le hore na o na le kalafo hangata hakae.

• U kanna ua ba le mofuthu kapa kutloahalo haufi le sebaka sa ho buoa.
• U ka ba le bofubelu, bonolo, kapa esita le tšoaetso.
• Mokotla o mokelikeli (seroma) o ka hlaha sebakeng sa ho buoa mme o ka hloka ho ts'oaoa.
• Letlalo la hau holim'a sebaka se alafiloeng le ka fetoha le le lefubelu kapa le lefifi ka 'mala, lekhapetla kapa ho hlohlona.

Litla-morao tsa nako e telele li kenyeletsa:

• Ho fokotsa boholo ba matsoele
• Ho tiea ho eketsehileng ha sefuba kapa asymmetry
• Bofubelu ba letlalo le ho soeufala

Ha ho so be le lithuto tsa boleng bo holimo tse bapisang brachytherapy le radiation eohle ea matsoele. Leha ho le joalo, lithuto tse ling li bonts'itse sephetho se ts'oana le sa basali ba nang le mofetše oa matsoele.
