“…Meningioma was diagnosed many years after RxT only in two patients. The occurrence of a second neoplasm in the field of irradiation has been already described as a rare event (41)(42)(43). In our opinion the causal relationship between the two events needs to be demonstrated, with the use of a proper control group (non-irradiated acromegalics), because we have observed the occurrence of meningioma even in some acromegalic patients not irradiated and an increase of tumor prevalence has been already shown in this population (3).…”

“…dose delivered had been 45:08^0:98 Gy, the mean number of fractions had been 22.4 and the mean dose for each fraction 200 Gy. The three-field technique using an opposed pair of lateral beams with a third anterior or vertex beam had been used in seven patients; the opposed lateral fields only had been used in 41 Patients had been followed-up at regular intervals (at least every 12 months for clinical and hormonal evaluation and at least every 5 years for neuroradiological evaluation) up to the last control. Hormonal data at each control were recorded in two categories, according to whether or not anti-GH treatment was still ongoing or had been withdrawn (for at least 2 months).…”

“…11,34,37 Delayed pituitary failure after regional radiation therapy has also been well described and may occur in 30-70% of patients who receive conventional radiotherapy. 2,9,33 Other complications include secondary malignancies 3,42,49 and temporal lobe necrosis.…”

“…При этом гамма-те-рапия уже утратила свои лидирующие по-зиции, настоящее и будущее принадлежит стереотоксической радиохирургии [25], ко-торая дает возможность применять доста-точные для облучения кортикотропином до-зы 70-90 Грей, в то время как риск раз-вития вторичных опухолей головного мозга составляет всего лишь 1-2 % [26]. Стереоток-сическая радиохирургия позволяет эффек-тивно контролировать гиперкортизолемию у 50-60 % больных через 3-5 лет после ее проведения [27,28].…”

“…Стереоток-сическая радиохирургия позволяет эффек-тивно контролировать гиперкортизолемию у 50-60 % больных через 3-5 лет после ее проведения [27,28]. По данным J. P. Sheehan и соавт., контроль над кортикотропиномой удавалось достичь у 98 % больных после сте-реотоксической радиохирургии [26]. Протон-ное облучение, как самостоятельный метод лечения, применяется при легкой и средней форме заболевания, а при среднетяжелой и тяжелой формах (для повышения эффек-тивности) его можно комбинировать с од-носторонней или двусторонней адреналэк-томией.…”
