Description of intervention(s) / exposure
The intra-cervical injection technique using radio-colloid and Patent Blue dye will be used for SLN mapping. The radio-colloid injection will be carried out on the day of the procedure and pre-operative lymphoscintigraphy with SPECT-CT will be obtained. Patients who have consented to the trial will be brought to the Nuclear Medicine Department at Royal Melbourne Hospital on the day of their planned surgery. In a similar manner to performing a pap smear, the cervix will be injected with 2mls of the radiocolloid, Technetium 99 at the 12, 3, 6 and 9 o’clock position. After the speculum is removed the patients will be asked to complete a Visual Analogue Score to assess pain related to the injection. The SPECT-CT will then be performed to track the route and nodal uptake of the radiocolloid and this information will be returned with the patient to the operating theatre. Under general anaesthetic after initial inspection of the peritoneal cavity, a gamma probe will be used to locate any hot nodes (at least 10 x the background activity). Two millilitres of Patent Blue dye will be injected into the cervix at the 3 and 9 o’clock positions. The SLN biopsy will be carried out prior to the hysterectomy and any nodes which are hot, blue, or both hot and blue will be removed and be set aside for separate histological examination. Hot nodes will be confirmed ex vivo (by counting activity for 3 to 10 seconds) and the nodal basins will be checked for any further nodes. All identified sentinel nodes will be removed and their location noted.
Women with presumed low risk disease will undergo a hysterectomy and bilateral salpingo-oophorectomy and only SLN identified at the time of the procedure will be removed.
Intervention code [1] 286172 0
Treatment: Surgery
Comparator / control treatment
The standard care for these patients includes a hysterectomy (+/- removal of the ovaries) followed by frozen section and depending on this result lymph node dissection. In this study standard of care (as above) will be followed for those patients where cancer is identified at frozen section however only the sentinel node that was identifed during the scan will be removed. Other nodes will only be removed if indicated.

Frozen section will only be done once, before lymph node dissection in standard of care and before sentinel node dissection in this study.

This is feasibility study with no randomisation intended at recruitment. It is hoped that this study will form the basis of a larger study (preferably multicentre) which would allow a calculation of the sensitivity and specificity of sentinel node detection in an Australian population.

Summary
Brief summary
The aim of this pilot study is to assess the feasibility of sentinel lymph node detection in patients with apparent early stage endometrial carcinoma in the Australia setting.

The hypothesis is that carrying out SLN detection in women with presumed early stage endometrial cancer, would prevent the morbidity associated with a formal pelvic lymph node dissection while attempting to identify the cohort that will be upstaged on final pathology. This will help to identify the women who could potentially benefit from adjuvant radiotherapy in preventing a loco-regional recurrence following the management of endometrial cancer.

This feasibility study will help us determine if SLN detection is feasible in women with low risk endometrial cancer.
