I'm really sorry to hear about this my dear brother ardianto. Apologies as I did not see this thread earlier.
Without doubt you must remain hopeful, for how many times have doctors said something but Allaah (swt)'s Plan was completely different? Everything is in Allaah (swt)'s Power and Control and He is the One who answers and responds to du'a.
Also, I'd like to emphasise to be persistent in reading Qur'an and du'as from the Sunnah over your wife, as these are a means of healing that we have been taught in Islam. Read them with faith and conviction and trust in Allaah (swt).
May Allaah (swt), Lord of the Magnificent Throne, grant complete shifaa' to your wife and leave no trace of illness, may He (swt) cause all of her suffering to be a means of expiation and purification for her sins, may He (swt) give both of you the strength and patience to endure this trial, and may He (swt) bless both of you with many happy years of sincere obedience and worship of Allaah (swt), Aameen!
Please do keep us updated Insha'Allaah.
Wassalaamu Alaykum Warahmatullahi Wabarakatuh.
