Acromegaly, if untreated, leads to numerous complications and premature death of patients. In recent years, significant changes in the treatment of acromegaly were achieved. The surgical approach was innovated, what allows completely selective removal of most microadenomas without any damage of the pituitary and safe debulking of the tumor mass in macroadenomas. Radiosurgery took the first place among irradiation methods, in our conditions it is the irradiation by the Leksell gamma knife. It allows selective irradiation of an adenoma without damaging the surrounding tissue. However, its effect on the secretory activity of the adenoma remains to be long lasting. Before this effect is attained, it is necessary to suppress the secretory activity pharmacologically. The infrequently effective, but economically advantageous and comfortable for patients is cabergoline, which is administered in tablet form. If cabergolin is not efficient, depot injections of somatostatin analogues - octreotide LAR and lanreotide autogel or their combination with cabergoline are used. The most efficient but financially costly is pegvisomant, blocking the receptors for growth hormone. In our conditions it is reserved for patients unresponsive to other treatments. With sufficient dosage it is possible to normalize hormonal activity of acromegly in 95 % of patients. New forms of the drugs as octreotide implants, oral octreotide octreolin or a new blocker of growth hormone receptors ATL-1103 are in the development.
肢端肥大症若不治疗,会导致患者出现诸多并发症并过早死亡。近年来,肢端肥大症的治疗取得了显著进展。手术方法有所创新,能够完全选择性地切除大多数微腺瘤,而不会对垂体造成任何损伤,对于大腺瘤也能安全地减少肿瘤体积。在放射治疗方法中,放射外科占据首位,在我们的情况下,是使用Leksell伽玛刀进行照射。它能够选择性地照射腺瘤而不损伤周围组织。然而,其对腺瘤分泌活性的影响仍有待持久显现。在达到这种效果之前,有必要通过药物抑制分泌活性。卡麦角林对患者来说效果不常显著,但经济上有利且使用方便,它以片剂形式给药。如果卡麦角林无效,则使用生长抑素类似物的长效注射剂——奥曲肽长效释放制剂和兰瑞肽凝胶剂,或者它们与卡麦角林的联合使用。最有效的但费用高昂的是培维索孟,它能阻断生长激素受体。在我们的情况下,它仅用于对其他治疗无反应的患者。给予足够剂量时,95%的肢端肥大症患者的激素活性可以恢复正常。新型药物如奥曲肽植入剂、口服奥曲肽奥曲林或新型生长激素受体阻滞剂ATL - 1103正在研发中。
