Brief summary

The primary endpoint of the present prospective study is to assess the outcomes in terms of acute toxicity of post-operative stereotactic radiotherapy for endometrial cancer

Detailed description

Endometrial cancer represents the sixth global female cancer, and adjuvant radiotherapy has a main role in the management of these patients. This treatment usually covers the surgical bed, the upper portion of the vagina and the pelvic lymph nodes. In the last decades, the technological progress has allowed clinicians to offer a more accurate planning and delivery of the treatment with modern IMRT-IGRT techniques. Nonetheless, radiotherapy regimens were still based on 25-30 fractions schedules. More recently, similarly to other oncological settings like prostate, breast or rectal cancer, 5-fractions schedules have been considered as potentially useful also in this setting. On this purpose, this study aims to investigate the feasibility of a shorter adjuvant radiotherapy treatment for endometrial cancer, by assessing acute and late toxicity, quality of life and clinical outcomes.

Design outcomes

Primary

MeasureTime frameDescription
Acute G3 or higher Gastrointestinal and Genitourinary ToxicityFrom the end of treatment to a time interval of 12 weeksThe number of any G3 or higher adverse event occurring within 90 days from the end of radiotherapy and assessed according to the CTCAE v5.0 criteria

Secondary

MeasureTime frameDescription
Late Gastrointestinal and Genitourinary ToxicityFrom enrollment to a follow-up time of 5 yearsThe number of any G3 or higher adverse event occurring after 90 days from the end of radiotherapy and assessed according to the CTCAE v5.0 criteria
Distant Progression Free SurvivalFrom enrollment to a follow-up time of 5 yearsThe rate of distant failure of the disease in all the participants enrolled for adjuvant SBRT
Local ControlFrom enrollment to a follow-up time of 5 yearsThe rate of local failure of the disease in all the participants enrolled for adjuvant SBRT
Overall SurvivalFrom enrollment to a follow-up time of 5 yearsThe rate of death events in the cohort of patients enrolled
Overall Quality of LifeFrom enrollment to a follow-up time of 5 yearsThe mean values of Quality of life questionnaires performed at baseline and at 3-6-12-18-24-36- 48-60 months from the end of treatment, with the QLQ-C30 and QLQ-EN24 fulfilled by all patients enrolled
