Eligibility
Key inclusion criteria
- Patients with newly biopsy proven advanced stage gynecological cancers (excluding
ovarian cancers) and endometrium in whom definitive (chemo)radiotherapy with curative
intent is planned are qualified for the study, as well as, patients with recurrent
gynecological cancers (excluding ovarian cancers) for which no prior (chemo)radiation
was performed for which (chemo)radiotherapy with curative intent is planned.

- Patients with para-aortic metastatic nodes (stage IVB) to the level of L2 are also
eligible but patients with further dissemination are not.

- Staging according to FIGO (2018, https://doi.org/10.1002/ijgo.12611) and TNM (version
9, 2021, https://doi.org/10.3322/caac.21663) staging.

- Patients who gave informed consent to take part in the MOMENTUM study (NCT04075305) to
use their clinical data for publication and share their data with other (European)
sites.

Summary
Brief summary
The goal of this observational study is to explore the effectiveness and side effects of a
high dose daily adapted SBRT (stereotactic body radiotherapy) boost delivered with MRLinac in
patients with gynaecological cancers that cannot receive a brachytherapy boost to the primary
tumour for different reasons (medical conditions, tumour extensions, etc). Current
alternative for brachytherapy in these situations is often a non-adaptive conebeam- CT guided
boost. Conebeam-CT guided non-adaptive high dose SBRT in under these circumstances is
described being quite toxic.

The main questions this study aims to answer are:

- In how many cases could local control (i.e. total disappearance of the tumor) is be
achieved with this treatment?

- Which side effects are observed in patients receiving this treatment?

Participants will be asked to fill out questionnaires (e.g. regarding side effects).
Furthermore, participants are asked if their clinical data may be used for study purposes.
