Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - TH BSO with SNB Note: If participants (=45yo), Grade 1 endometrial adenocarcinoma with myometrial invasion <50%, wish to retain their ovaries a BSO may be omitted
Treatment: Surgery - TH BSO without retroperitoneal node dissection Note: If participants (=45yo), Grade 1 endometrial adenocarcinoma with myometrial invasion <50%, wish to retain their ovaries a BSO may be omitted

Experimental: TH BSO with SNB - Total Laparoscopic/Robotic Hysterectomy, Bilateral Salpingo-Oophorectomy (TH BSO) with Sentinel Node Biopsy (SNB) using Indocyanine Green (ICG)+/- Methylene Blue Dye (+/- omentectomy in high risk cell types) Note: If participants (=45 years of age), have Grade 1 endometrial adenocarcinoma (EAC) with myometrial invasion \<50% (by MRI) and wish to retain their ovaries a BSO may be omitted.

Active comparator: TH BSO without retroperitoneal node dissection - Total Laparoscopic/Robotic Hysterectomy, Bilateral Salpingo-Oophorectomy (TH BSO) without retroperitoneal node dissection (+/- omentectomy in high risk cell types) Note: If participants (=45 years of age), have Grade 1 endometrial adenocarcinoma (EAC) with myometrial invasion \<50% (by MRI) and wish to retain their ovaries a BSO may be omitted.


Treatment: Surgery: TH BSO with SNB Note: If participants (=45yo), Grade 1 endometrial adenocarcinoma with myometrial invasion <50%, wish to retain their ovaries a BSO may be omitted
Removal of uterus, tubes and ovaries with a sentinel node biopsy. A tracer dye (ICG) +/- Methylene Blue Dye is injected into the surroundings of the primary tumour, it is transported via local lymphatic channels towards the draining lymphatic basin, and the first node that the tracer reaches is called the "sentinel node". These one or two nodes are thought to be first involved with cancer spread.

Treatment: Surgery: TH BSO without retroperitoneal node dissection Note: If participants (=45yo), Grade 1 endometrial adenocarcinoma with myometrial invasion <50%, wish to retain their ovaries a BSO may be omitted
Removal of uterus, tubes and ovaries without retroperitoneal node dissection
