该文报道30例经病理证实的侵袭性垂体腺瘤。作者认为侵袭性垂体腺瘤是界于良性垂体腺瘤和恶性垂体癌之间的肿瘤,共组织学形态属良性,但生物学特性却似恶性肿瘤。垂体腺瘤术后复发的根源在于此瘤的侵袭率高,术中不可能将其侵袭生长于硬膜、结缔组织内的腺瘤全部刮除;术后早期辅以放疗可能有助于减少垂体腺瘤的复发。
This article reports 30 cases of invasive pituitary adenoma confirmed by pathology. The authors believe that invasive pituitary adenomas are borderline between benign pituitary adenomas and malignant pituitary carcinomas. The co-histological morphology is benign, but the biological characteristics are like malignant ones. The root cause of postoperative recurrence of pituitary adenomas is the high invasion rate of this tumor. It is impossible to remove all the adenomas that invade and grow in the dura mater and connective tissue during operation. The early postoperative radiotherapy may help reduce the pituitary. Recurrence of adenomas.
