Summary
This study focused on patients with type I neurofibromatosis, who currently lack effective drug therapy and have a high recurrence rate after surgical resection. As a MEK inhibitor, Smetinib bisulfate capsule can induce tumor shrinkage by selectively binding mitogen-activated protein kinase (MEK) 1/2 protein, blocking the mitogen-activated protein kinase/extracellular signal regulatory kinase signaling pathway that regulates key cell responses. To create conditions for disease control, radical surgical resection, reducing postoperative recurrence and reducing complications. The purpose of this study was to provide treatment with Smetinib bisulfate for patients with type I neurofibromatosis, observe the therapeutic effect in stages, convert patients without surgical indications into patients with surgical indications, increase the proportion of surgical resection and reduce the recurrence rate. Objective tumor response rate (ORR) after drug treatment was used as the main outcome index in this study. The resectable scope, duration of remission (DOR), progression-free survival (PFS) were used as secondary outcome indicators to investigate the improvement of resectable rate, reduction of resectable scope and postoperative complications, tumor shrinkage effect, and the stability of curative effect of the use of smetinib bisulfate capsule on type I neurofibromatosis.
