摘要

Purpose

Craniopharyngiomas are histologically benign tumors, but their proximity to vital neurovascular structures can significantly deteriorate functional prognoses and severely restrict patients’ social interaction and activity. We retrospectively identified risk factors related to the functional prognoses in patients with craniopharyngioma treated at our center.

Methods

A retrospective analysis was conducted on 40 patients who underwent surgery for craniopharyngioma and follow-up at our institution between 2003 and 2022. Functional prognoses were evaluated in terms of obesity (body mass index [BMI] ≥ 25 for adults, BMI-Z ≥ 1.65 for children), visual function, endocrine function, and social participation. We investigated whether patient characteristics, tumor size, tumor location, hypothalamic involvement, surgical hypothalamic damage, extent of resection, and recurrence rate correlated with these functional prognostic factors.

Results

The median age at diagnosis was 28.0 years, with a median follow-up of 80.5 months. Postoperative obesity was present in 22 patients, and those with postoperative obesity had a significantly higher preoperative BMI or BMI-Z (preoperative BMI for adults: p = 0.074; preoperative BMI-Z for children: p = 0.020) and were significantly correlated with preoperative hypothalamic involvement grade 2 (p = 0.012) and surgical hypothalamic damage grade II (p = 0.0001). Deterioration in social participation was significantly associated with a larger tumor size (p = 0.023) and tumor recurrence (p = 0.0047).

Conclusions

Patients with higher preoperative BMI or BMI-Z and hypothalamic involvement have a greater risk of postoperative obesity, and larger tumor size and recurrence can significantly deteriorate the rate of patients’ social participation.
