Postoperative functional status in patients with supratentorial superficial low-grade glioma

Abstract

Background: We investigated the functional status of adult supratentorial superficial low-grade glioma (ASS-LGG) after surgery and analyzed its relevant factors to guide the therapeutic strategy and improve the life quality of these patients. Methods: Clinical materials from January 2008 to December 2010 in 104 adults with ASS-LGG were analyzed retrospectively. The follow-up period ranged from 6months to 1.5years. The logistic regression was used to evaluate the preoperative and postoperative variation of functional status in patients to disclose the relevant factors affecting postoperative functional status, such as age, gender, the duration of symptom, size and location of the tumor, hemisphere, resection degree, and tumor pathologic grade and preoperative Karnofsky performance status (Pre-KPS). Results: Four out of nine candidate factors are related to the postoperative functional status. They are age less than 40years, the size of tumor less than 5cm in diameter, tumor located in the right hemisphere, and limited resection of tumor in the eloquent area. Conclusions: It seems more meaningful to evaluatethe functional status of the patients with ASS-LGG on the basis of these clinical features, involving age, tumor size, location, and extent of resection.
