follow-up period was 12 months (ranging from 1 to 27 months), and the median age was 58 years (ranging from 28 to 92 years). Most patients (63) completed their treatment with brachytherapy (administered as 4x7 or 2x5.5 Gy). Upon analyzing the D2% and Dmed doses received by the sacrum, the median values observed were 43.99Gy (ranging from 20.49 to 53.75 Gy) and 28.79 Gy (ranging from 9.29 Gy to 35.97 Gy), respectively. Notably, no cases of SIF were identified in this cohort treated with VMAT.

Conclusion: In our cohort treated with the highly conformal VMAT technique, we observed optimal results and a lower incidence of SIFs within the specified dosage range. The dose delivered to the sacrum was reduced. However, to validate these findings, further prospective studies with larger sample sizes and extended follow-up periods are necessary.

Keywords: SIFs, VMAT, gynecologic cancers.

Malnourished patients suffer a greater deterioration in quality of life, an increase in treatment toxicity, a worsening of oncological results and a greater expenditure of health resources. Our aim is to show the importance of implementing nutritional in daily clinical practice to detect malnourished patients early and begin a nutritional intervention to mitigate the consequences of malnutrition.
