Umuti mushya wongera igihe cyo kubaho k'umurwayi wa kanseri y'urwagashya (Pancreas).

Uyu muti witwa daraxonrasib ugaragara nk’intambwe ikomeye mu guhangana na kanseri y’urwagashya, imwe mu kanseri zica abantu benshi kurusha izindi.

Uyu muti ukora uhagarika ikwirakwira rya kanseri binyuze mu gufunga no guhagarika gene ya KRAS yahindutse (mutated KRAS), iboneka mu bibyimba bya kanseri y’urwagashya birenga 90%, kandi ikaba ari yo ituma kanseri ikura vuba.

Ubushakashatsi bwakorewe ku barwayi 500 bo muri Canada, Europe, na Asia bwagaragaje ko:

Abarwayi bavurwaga hakoreshejwe chimiotherapie (chemotherapy) babayeho impuzandengo y’amezi 6.
Abafashe daraxonrasib babayeho impuzandengo y’amezi 13.2.

Byongeye kandi, uyu muti wateye ingaruka nke ugereranyije n’ubundi buryo bwo kuvura.

Rachna Shroff, umuyobozi w’ishami rya hematology na oncology muri University of Arizona Cancer Center, yavuze ko:

“Ibi bivuye muri ubu bushakashatsi bishobora guhindura cyane uburyo abarwayi ba kanseri y’urwagashya yakwirakwiriye bafite ihinduka rya KRAS bavurwa.”

Kanseri y’urwagashya akenshi iboneka itinze kandi kuyivura biragorana cyane. Abantu barenga kimwe cya kabiri bayirwara bapfa mu mezi atatu ya mbere nyuma yo kuyisuzumirwa.

Mu Bwongereza, abantu bagera ku 11,500 bayisuzumirwaho buri mwaka, naho abagera ku 10,200 bakicwa na yo.

Umukinnyi wa filimi Alan Rickman yapfuye azize iyi ndwara mu mwaka wa 2016, nyuma y’amezi atanu gusa ayisuzumwe.

Ibimenyetso bya kanseri y’urwagashya bishobora kuba:

Uruhu n’amaso bihinduka umuhondo (jaundice)
Kwishimagura ku ruhu
Inkari zijimye cyane
Umusarani wera cyangwa woroshye mu ibara
Kugabanuka ibiro nta mpamvu izwi
Umunaniro ukabije
Umuriro cyangwa ubushyuhe bwinshi bw’umubiri

Kanseri ya pancreas (urwagashya) iragorana kuyisuzuma kuko ibimenyetso byayo akenshi bitagaragara mu ntangiriro z’indwara, kandi bishobora kwitiranywa n’ibindi bibazo by’ubuzima.

Ubushakashatsi bwakozwe n’abashakashatsi bo muri Amerika kandi bwatangarijwe mu nama ngarukamwaka ya American Society of Clinical Oncology yabereye mu Chicago, bwakorewe ku barwayi 500.

Muri abo:

Abarwayi 248 bahawe umuti wa daraxonrasib.
Abarwayi 252 bahawe chemotherapy.

Abenshi muri bo bari bafite ibibyimba bya kanseri bifite ihinduka ryihariye rya gene ya KRAS.

Uretse kuba uyu muti wongerera abarwayi igihe cyo kubaho ku buryo bugaragara, unafatwa rimwe ku munsi kandi ugatera ingaruka mbi nke ugereranyije na chemotherapy.

Ubushakashatsi bwagaragaje ko:

Ingaruka zikomeye zagaragaye ku 43.6% by’abafashe daraxonrasib.
Mu gihe ku bafashwe na chemotherapy zagaragaye ku 57.5%.

Anna Jewell, umuyobozi ushinzwe serivisi, ubushakashatsi n’udushya muri Kanseri y’urwagashya mu Bwongereza, yavuze ko:

“Ubu buryo bwo kuvura buri mu byateye icyizere kurusha ibindi twabonye mu rwego rwa kanseri y’urwagashya mu gihe kirekire cyane.”

Yongeyeho ati:

“Kugira igihe kinini cyo kubana n’abo dukunda ni ikintu gifite agaciro ntagereranwa. Tugomba gukora ibishoboka byose kugira ngo ubu buryo bushya bwo kuvura butanga icyizere buboneke no mu Bwongereza ndetse n’isi yose.”
