Abstract
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.

Core Tip: Calcifying fibrous tumors (CFTs) are rare and benign mesenchymal neoplasms with a low risk of recurrence and are cured by local removal. The treatment of CFTs primarily aims to relieve symptoms, such as intussusception and obstruction. Gastrointestinal calcifying fibrous tumors can be removed using endoscopic procedures.
