Can I receive gamma knife radiotherapy after pituitary adenoma surgery?

Pituitary tumor is one of the common benign intracranial tumors. Patients can be diagnosed by head CT or MRI examination and endocrine examination combined with clinical symptoms. In the choice of treatment methods for pituitary adenoma, the main treatment methods are surgery and radiotherapy, but because the curative effect of drug therapy on pituitary adenoma is not obvious, drug therapy is generally not chosen. Gamma knife was used to consolidate the curative effect and prevent recurrence after operation. Although the histological examination of pituitary adenoma is benign, it can break through the capsule and grow infiltratively, thus invading adjacent tissues and structures. Therefore, postoperative gamma knife radiotherapy is usually needed to reduce the recurrence rate. Because even if pituitary adenoma is completely removed during operation, the 5-year recurrence rate is still as high as 15%. Therefore, it is very suitable for patients with pituitary adenoma with residual or recurrent tumor tissue after operation, as well as patients with small tumor volume and unaffected visual field. The gamma knife mentioned here is a kind of radiotherapy, not a real scalpel. It is a hemispherical helmet covered with collimator, which can emit 20 1 large dose gamma rays of cobalt 60. Gamma knife positioning is extremely accurate, and the error is often less than 0.5 mm By converging 20 1 rays at different positions, tumor tissue can be fatally destroyed, which has the advantages of less trauma, no need for surgery and short treatment time. The incidence of pituitary hypofunction after conventional radiotherapy is 13% ~ 56%, while the total tumor control rate of gamma knife for pituitary adenoma is 95%, and the tumor control rate of microadenoma is higher, about 100%. The incidence of hypopituitarism was 65438 00%. Gamma Knife Treatment Center of Zibo Wanjie Cancer Hospital —— the first Zibo Wanjie Cancer Hospital in China —— is a provincial, municipal and district-level medical insurance designated hospital, featuring non-invasive and minimally invasive high-tech means, and it is also one of the first three private pilot hospitals approved by the Ministry of Health and the then Ministry of Foreign Trade and Economic Cooperation. 1993, Zibo wanjie cancer hospital introduced the first gamma knife equipment in China and established the first gamma knife treatment center in China. 1995 introduced the second gamma knife, and in 20061kloc-0/c, a new generation of highly intelligent and automated gamma knives represented the contemporary gamma knife technology in the world. It is the only high-tech hospital in China with two Lekse 1 1C gamma knives. Up to now, more than 30,000 cases of intracranial tumors have been treated with gamma knives. Relying on rich clinical research experience, the center makes full use of advanced diagnostic equipment such as four-dimensional PET-CT and 3.0T magnetic vibration, and perfectly combines traditional surgery with a team of experts with high technical content and exquisite skills. Six doctors became members of the International Gamma Knife Association with excellent academic achievements and professional skills, accumulated rich clinical experience and achieved fruitful scientific research results. * * * Published more than 0/00 academic papers in professional journals.
