Endoscopic resection for calcifying fibrous tumors of the gastrointestinal tract.

Background: Calcifying fibrous tumors (CFTs) are rare mesenchymal lesions that can occur in various sites throughout the body, including the tubular gastrointestinal (GI) tract.
Aim: To analyze the clinical findings of 36 patients with GI tract CFTs to provide guidance for diagnosis and treatment.
Methods: This retrospective study included 36 patients diagnosed with CFTs of the GI tract. We collected demographic and clinical information and conducted regular follow-ups to assess for local recurrence.
Results: The stomach was the most commonly involved site, accounting for 72.2% of the 36 CFTs. Endoscopic mucosal resection ( n = 1, 2.8%), endoscopic submucosal dissection ( n = 14, 38.9%), endoscopic full-thickness resection ( n = 16, 44.4%), and submucosal tunneling endoscopic resection ( n = 5, 13.9%) were used to resect calcifying fibrous tumors. Overall, 34 (94.4%) CFTs underwent complete endoscopic resections with a mean procedure time of 39.8 ± 29.8 min. The average maximum diameter of the tumors was 10.6 ± 4.3 cm. No complications, such as bleeding or perforation, occurred during an average hospital stay of 2.9 ± 1.2 d. In addition, two patients developed new growth of CFTs near the primary tumor sites, and none of the patients developed distant metastases during the follow-up period.
Conclusion: GI tract CFTs are rare and typically benign tumors that can be effectively managed with endoscopic procedures.
