Aggressive pituitary tumor has the possibility to be cured. Aggressive pituitary tumor refers to the invasion and development of the tumor to both sides of the pituitary fossa, the tumor invades the cavernous sinus, the internal carotid artery and the important cranial nerves on both sides of the pituitary fossa, and forms adhesion and wrapping with these tissues, which increases the difficulty of surgery, and it is very difficult to remove the tumor completely by surgery in general. However, with the advancement of medical technology and medical equipment, it is possible to achieve total resection of invasive pituitary tumor, because pituitary tumor is a benign tumor, once total resection of the tumor will achieve the purpose of cure, and the tumor will not recur. However, if the tumor is very closely adhered to important blood vessels and nerves, it is very difficult to achieve total resection. Without total resection, the tumor will not be cured, and the tumor will recur and need to be operated again, and it is much more difficult to achieve total resection of the tumor in another operation, and the tumor cannot be totally resected, so the patient will have recurrence again and again, and the goal of cure cannot be achieved.
