Official Title: Preoperative Imatinib Mesylate Combined With Rectal-sparing Surgery in Patients With c-KIT Gene-mutant Rectal GIST: an Open-label, Single-arm, Phase III Trial(PIRKER)

Study ID: NCT05970900

Study Description

Brief Summary: Prior to the implementation of preoperative imatinib mesylate therapy, a considerable percentage (ranging from 34.5% to 67.5%) of individuals diagnosed with rectal gastrointestinal stromal tumors (GIST) underwent abdominoperineal resection (APR), a surgical procedure that involved the removal of the anus and necessitated a permanent colostomy. This study aims to investigate the safety and viability of an organ-preserving approach involving preoperative imatinib mesylate treatment in conjunction with local resection for rectal GIST, specifically targeting patients with c-KIT gene mutations.

Detailed Description: Prior to the implementation of preoperative imatinib mesylate therapy, a considerable percentage (ranging from 34.5% to 67.5%) of individuals diagnosed with rectal gastrointestinal stromal tumors (GIST) underwent abdominoperineal resection (APR), a surgical procedure that involved the removal of the anus and necessitated a permanent colostomy. Previous studies have established that preoperative administration of imatinib mesylate effectively diminishes the size of rectal gastrointestinal stromal tumors (GIST) and enhances the likelihood of sphincter preservation. After initiating preoperative imatinib mesylate treatment, the sphincter preservation rate has notably escalated from 4.2% to 33.0%-94.9%. In theory, lymph node resection is not required for Gastrointestinal Stromal Tumors (GIST); the local excision of rectal GIST enables sphincter preservation and yields satisfactory anal function and quality of life (QoL). Various surgical techniques are utilized for local excision, including traditional transanal (TA) and transanal minimally invasive surgery (TAMIS) approaches. This study aims to explore the safety and feasibility of an organ-preservation strategy of preoperative imatinib mesylate combined with local resection in rectal gastrointestinal stromal tumor (GIST), specifically for patients with c-KIT gene mutations.
