A New Clinical Prognostic Scoring System for Pituitary Adenoma

Objective: Clinical manifestations of pituitary adenomas are the most changeful and directly associated with prognosis. In the past three years, we have established a new clinical prognosis score systerm for preoperative pituitary adenomas. We try to use this score systerm to help the neurosurgeon choose therapy strategy and evaluate the risk correctly.

Materials and methods: New clinical prognosis score systerm for preoperative pituitary adenomas were based on MRI image, Visual manifestations and Endocrinological dysfunction. 756 cases were admitted to prove the reliability and validity of the new score systerm. The clinical information of each case were cllected carefully, such as MRI image, result of visal test, endocrinological dysfunction,surgical approach,amount of bleeding,hours of operationa,expense and so on. All the data were statistically.

Results: The reliability and validity of the new clinical prognosis score systerm for preoperative pituitary adenomas are very good. The highest score is set to 10. There are 666 cases(88%) with low scores(< 6) got satisfied result, especially those cases got score less than 3. 90 cases(12%) got scores over 6 suffer diffcult treatment and high cost.

Conclusion: The new clinical prognosis score systerm for preoperative pituitary adenomas are accuracy and easy to use. The higher the score the worse prognosis.Those cases which got high score faced with greater risks and more cost.
