ʻO ka ʻenehana 3D i ka mālama ʻana i ka maʻi kanesa? E kamaʻilio maʻalahi kākou e pili ana i ka 3D-CRT (Three-Dimensional Conformal Radiation Therapy)

Nui ka poʻe o kākou e makaʻu nei ke lohe kākou i ka huaʻōlelo kanesa. He makaʻu nui ko kākou i ka radiation therapy . He mea maʻamau ka noʻonoʻo ʻana, "Auē, e hoʻopilikia anei kēia i nā ʻāpana olakino o ke kino?" Akā, ua holomua loa ka ʻenehana o kēia wā. I kēia lā, ke kamaʻilio nei kākou e pili ana i kahi hoʻolālā lapaʻau radiation kūikawā e kuhikuhi pono ana i ka puʻupuʻu kanesa a hoʻemi i ka hōʻino ʻana i nā ʻōpū olakino a puni. ʻO ia hoʻi ʻo 3D-CRT.

He aha kēia 3D-CRT?

I ka ʻōlelo maʻalahi, ʻo 3D-CRT kahi ʻenehana holomua loa i hoʻohana ʻia e hoʻolālā i ka External Beam Radiation Therapy (EBRT) no ka maʻi kanesa. ʻAʻole ia ka lāʻau lapaʻau ponoʻī, akā, ʻo ia ka hoʻolālā no ka lāʻau lapaʻau .

E noʻonoʻo ʻoe e hele ana i kahi mea hana lole e hana i kahi lole. Lawe ʻo ia i kāu mau ana pololei a hana i ke kapa e kūpono iā ʻoe, ʻeā? Pēlā nō ka 3D-CRT. Maanei, loaʻa i nā kauka oncologists radiation kahi hiʻohiʻona ʻekolu-dimensional (3D) o kāu puʻupuʻu kanesa a me nā ʻōpū olakino a puni.

No ka loaʻa ʻana o kēia ʻike 3D, hoʻohana ʻia nā kiʻi mai nā hoʻokolohua diagnostics e like me ka scan `CT (Computed Tomography)`, scan ` MRI (Magnetic Resonance Imaging)`, a i ʻole scan `PET ( Positron Emission Tomography )`. Hoʻopili nā polokalamu kamepiula kūikawā i kēia mau kiʻi a hana i kahi `palapala ʻāina 3D` o ka nui, ke ʻano, a me kahi kikoʻī o ke kanesa.

He aha nā hoʻohana o ka 3D-CRT?

Hoʻohana nā kauka maʻi kanesa i kēia ʻano hoʻolālā 3D-CRT e mālama i nā ʻano maʻi kanesa like ʻole. He mea nui loa kēia ʻano hana i nā hihia kahi hiki ʻole ai ke ʻoki kino. Hāʻawi pū ia i ka radiation therapy i hoʻolālā ʻia e hoʻēmi i ka puʻupuʻu ma mua o ke ʻoki kino (`neoadjuvant therapy`) a i ʻole e luku i nā hunaola maʻi kanesa i koe ma hope o ke ʻoki kino (`adjuvant therapy`).

Aia ma lalo iho kekahi o nā ʻano maʻi kanesa maʻamau e hoʻohana ʻia ai ka 3D-CRT.

Pehea e hoʻohana ʻia ai ʻo 3D-CRT i ka hoʻolālā lapaʻau?

Na kāu hui lapaʻau e alakaʻi iā ʻoe ma o kēia kaʻina hana hoʻolālā 3D-CRT i kēlā me kēia ʻanuʻu.

1. Ke hana ʻana i kahi Palapala ʻĀina 3D

ʻO ka mea mua, e like me kā mākou i kūkākūkā ai ma mua, lawe ʻia nā kiʻi mai kāu CT a me MRI scan a hana kahi polokalamu kamepiula i kahi palapala ʻāina 3D o ka puʻupuʻu. Hoʻokomo ʻia kēia palapala ʻāina i loko o ka mīkini e hāʻawi ana i ka radiation (ka `Linear Accelerator`).

2. Kaʻina hana hoʻohālike

Ua like kēia me kahi hoʻomaʻamaʻa no kahi pāʻani. E hoʻomoe ʻia ʻoe ma luna o kahi papa lapaʻau a hoʻonoho ʻia e like me ʻoe e loaʻa ana i ka radiation therapy. I kēia manawa, e hoʻohana ʻia ka palapala ʻāina 3D e hoʻoholo i kahi a me ke kihi pololei o nā kukuna radiation.

3. Ke kau nei i nā māka ʻili

I ka wā o ka hoʻohālike ʻana, e kau ke kime lapaʻau i kekahi mau māka liʻiliʻi loa, e like me nā kiko ma kou ʻili. He mau māka liʻiliʻi pinepine kēia (`peʻa`) e like me nā peʻa mau loa . Mai hopohopo ke ʻike ʻoe i kēia mau mea. Hoʻonoho ʻia kēia mau mea i loko o kēlā me kēia lāʻau lapaʻau, e kuhikuhi pololei ʻia ke kukuna radiation ma kahi o nā hunaola kanesa, me ka ʻole o ka neʻe ʻana i hoʻokahi milimita. E kōkua kēia mau māka iā ʻoe e mālama i kou kino ma ke kūlana like i kēlā me kēia lāʻau lapaʻau.

Ke hoʻopilikia nei anei ka 3D-CRT i nā hopena ʻaoʻao?

ʻO ka mea nui e hoʻomaopopo ma ʻaneʻi, he ʻano hoʻolālā ka 3D-CRT, ʻaʻole he lāʻau lapaʻau. No laila, ʻaʻohe hopena ʻaoʻao pololei i hoʻokumu ʻia e ke kaʻina hoʻolālā 3D-CRT.

Eia nō naʻe, hiki i ka radiation therapy i hāʻawi ʻia e like me kēlā hoʻolālā ke hana i kekahi mau hopena ʻaoʻao. ʻOiai ʻo 3D-CRT e hōʻemi nui i ka hōʻino ʻana i nā ʻiʻo olakino, hiki nō ke hōʻino ʻia kekahi mau mea. ʻO nā hopena ʻaoʻao e kū mai ana ma muli o ka wahi o ke kino e mālama ʻia ana.

Nā pono a me ka ʻenehana hou o 3D-CRT

ʻO ka pōmaikaʻi nui o ke ʻano 3D-CRT, ʻo ia ke kuhikuhi pololei ʻana i ka puʻupuʻu a hoʻemi i ka hōʻino ʻana i nā ʻiʻo olakino a puni.

Eia nō naʻe, i kēia lā, aia nā ʻano hoʻolālā lapaʻau radiation holomua ma mua o 3D-CRT. ʻO kekahi o lākou ʻo `Intensity-Modulated Radiation Therapy (IMRT)`.

Hoʻohana ʻo IMRT i nā kukuna liʻiliʻi he nui (nā kukui liʻiliʻi) ma kahi o hoʻokahi kukuna nui. Hiki ke hoʻololi ʻia ka ikaika o nā kukuna. Ua like ia me ka pena ʻana i kahi kiʻi me nā kaha pena liʻiliʻi like ʻole, ma mua o hoʻokahi kala. ʻAe kēia iā IMRT e hāʻawi i ka radiation e kūpono i ke ʻano paʻakikī o ka puʻupuʻu. Hōʻike kekahi mau haʻawina he emi iki paha nā hopena ʻaoʻao o IMRT.

Inā ua kuhikuhi ʻia ʻoe i ka radiation therapy, mai makaʻu e nīnau i kāu kauka a i ʻole ka hui lapaʻau e pili ana i ke kaʻina hana. He mea hōʻoluʻolu nui ia nou ke ʻike maopopo i nā mea āpau.
