Table 4 Comparison of tumor resection rate with postoperative hormone (n = 10) and postoperative visual acuity (n = 24) improvement

From: Analysis of operative efficacy for giant pituitary adenoma

Improvement Postoperative hormonea Postoperative visual acuityb
Unimproved Improved Remained Improved
Number of cases 2 8 9 15
Average tumor resection rate (%) 72.3 83.5 60.4* 79.5
  1. Note: aComparison of tumor resection rate in hormone levels in 10 patients with functional pituitary adenomas before and 24 hours after surgery. bComparison of tumor resection rate in visual acuity in 24 patients with decreased visual acuity before and 24 hours after surgery.
  2. *P < 0.05, average tumor resection rate with remained visual acuity vs. average tumor resection rate with improved visual acuity, Mann–Whitney U test.
