Abarwayi ba kanseri y'ibihaha, ese gupimwa MRD ni ngombwa?

MRD (Indwara ntoya zisigara), cyangwa indwara ntoya zisigara, ni umubare muto w'uturemangingo twa kanseri (uturemangingo twa kanseri tutitabira cyangwa turwanya kuvurwa) dusigara mu mubiri nyuma yo kuvurwa na kanseri.
MRD ishobora gukoreshwa nk'ikimenyetso cy'isuzuma, igisubizo cyiza kikaba gisobanura ko ibisebe bisigaye bishobora kugaragara nyuma yo kuvurwa kanseri (uturemangingo twa kanseri turaboneka, kandi uturemangingo twa kanseri dusigaye dushobora gukora no gutangira kwiyongera nyuma yo kuvurwa kanseri, bigatuma iyi ndwara yongera kugaruka), mu gihe igisubizo kibi bivuze ko ibisebe bisigaye bitagaragara nyuma yo kuvurwa kanseri (nta turemangingo twa kanseri twabonetse);
Birazwi ko gupima MRD bigira uruhare runini mu kumenya abarwayi ba kanseri y’ibihaha itari iy’uturemangingo duto (NSCLC) bari mu cyiciro cya mbere cy’abarwayi bafite ibyago byinshi byo kugaruka no mu kuyobora uburyo bwo kuvura nyuma yo kubagwa bikomeye.
Ibintu MRD ishobora gukoreshwamo:

Ku kanseri y'ibihaha ishobora kubagwa mu gihe cyo hambere

1. Nyuma yo gucibwa burundu abarwayi ba kanseri y'ibihaha batari basanzwe bafite kanseri nto, kuba bafite MRD bigaragaza ko bafite ibyago byinshi byo kongera kuyirwara kandi bisaba gukurikiranwa hafi. Gukurikirana MRD bigirwa inama buri mezi 3-6;
2. Ni byiza gukora ibizamini byo kwa muganga bya kanseri y'ibihaha itari iy'uturemangingo duto ishingiye kuri MRD, no gutanga uburyo bwo kuvura neza mu gihe cyo kubagwa uko bishoboka kose;
3. Saba gusuzuma uruhare rwa MRD mu barwayi bombi, abarwaye indwara ya gene positive na gene disadvative, ukwayo.

Ku ndwara ya kanseri y'ibihaha itari iy'uturemangingo duto iteye imbere mu gace runaka

1. Gupima MRD birasabwa ku barwayi bakize burundu nyuma yo kuvura kanseri y’ibihaha idasanzwe ku buryo budasanzwe, bishobora gufasha kumenya uko indwara ihagaze no gushyiraho izindi ngamba zo kuvura;
2. Igeragezwa ry’ubuvuzi rya MRD rishingiye ku buvuzi bwo gusimbuza nyuma ya chemotherapy rirasabwa kugira ngo habeho uburyo nyabwo bwo kuvura busimbuza uko bishoboka kose.
Ku kanseri y'ibihaha itari iy'uturemangingo duto iteye imbere
1. Hari ibura ry’ubushakashatsi bufatika kuri MRD muri kanseri y’ibihaha itari iy’uturemangingo duto;
2. Ni byiza ko MRD iboneka ku barwayi bakize burundu nyuma yo kuvurwa kanseri y’ibihaha itari iy’uturemangingo duto, ibi bikaba byafasha mu gusuzuma imiterere y’indwara no gushyiraho izindi ngamba zo kuvura;
3. Ni byiza gukora ubushakashatsi ku ngamba zo kuvura abarwayi bakize burundu hakoreshejwe MRD kugira ngo bongere igihe cyo kumererwa neza uko bishoboka kose kugira ngo abarwayi babashe kubona inyungu nyinshi.

Bigaragara ko kubera ko nta bushakashatsi buhagije bwakozwe ku bijyanye no gupima MRD muri kanseri y’ibihaha itari iy’uturemangingo duto, ikoreshwa rya MRD mu kuvura abarwayi ba kanseri y’ibihaha itari iy’uturemangingo duto ritaragaragazwa neza.
Mu myaka ya vuba aha, iterambere mu buvuzi bw’ibanze n’ubudahangarwa bw’umubiri ryahinduye icyerekezo cy’ubuvuzi ku barwayi bafite NSCLC iteye imbere.
Ibimenyetso bishya bigaragaza ko abarwayi bamwe babasha kubaho igihe kirekire ndetse bakaba biteze ko babasha kumererwa neza binyuze mu gupima. Kubwibyo, hashingiwe ku gitekerezo cy'uko amwe mu matsinda y'abarwayi bafite NSCLC ikomeye yagiye agera ku ntego yo kubaho igihe kirekire, gukurikirana indwara zo kugaruka byabaye ikibazo gikomeye mu buvuzi, kandi niba gupima MRD nabyo bishobora kubigiramo uruhare runini bikwiye gusuzumwa mu bindi bizamini by'ubuvuzi.
