ABSTRACT
INTRODUCTION:
Numerous studies have demonstrated Fractionated Stereotactic Radiotherapy's (FSRT) effectiveness in tumor control post-resection for craniopharyngiomas. Nevertheless, past literature has presented conflicting findings particularly regarding endocrine and visual function outcomes. This study aims to elucidate FSRT's efficacy and safety for this population.METHODS:
Adhering to PRISMA, a systematic review and meta-analyses was conducted. Included studies had to report the effects of FSRT for treating craniopharyngiomas in a sample greater than four patients, addressing at least one of the outcomes of interest improvement in visual acuity or field, new-onset hypopituitarism, effectiveness, and tumor progression. Relative risk with 95% confidence intervals were used to assess the outcomes.RESULTS:
After retrieving a total of 1292 studies, 10 articles met the predefined criteria and thus were finally selected, amounting to a total of 256 patients. The improvement in visual acuity was estimated at 45% (95% CI 6-83%), while the improvement in the visual field was 22% (95% CI 0-51%). Regarding endocrine function, the new-onset hypopituitarism rate was found to be 5% (95% CI 0-11%). Relative to FSRT effectiveness, the pooled estimate of the complete tumor response rate was 17% (95% CI 4-30%), and the tumor progression rate was 7% (95% CI 1-13%). Also, a 3-year progression-free survival rate of 98% (95% CI 95-100%) was obtained.CONCLUSION:
Despite limitations and risks, FSRT shows promise as a viable therapeutic option for craniopharyngiomas, offering notable benefits for visual functions and tumor control. Further research is required to better understand the associated risks, benefits, and clinical utility.Palavras-chave
