Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For patients undergoing surgical treatment for endometrial cancer - total laparoscopic hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy - indocyanine green dye (ICG) will be used to map sentinel lymph nodes: 1ml of ICG will be injected in 4 points of uterine cervix mucosa and stroma. Durign laparoscopic surgery in near infrared light a sentinel lymph nodes will be visualised and resected before proceeding with next surgery steps - total pelvic lymphadenectomy and hysterectomy. Duration of mapping procedure and sentinel lymphonode resection is aproximately 50 - 60 minutes.
This procedure will be performed by the surgeon.
Sentinel lymph nodes will be examined by pathologist using ultrastaging protocol to find micrometasis and isolated tumur cells (ITC)

Outcomes
Primary outcome [1] 320206 0
Detection rate of monolateral sentinel lymph nodes, verified by histology.
Timepoint [1] 320206 0
Final histological verification 14 days after surgery.
Primary outcome [2] 320207 0
Detection rate of bilateral sentinel lymph nodes, verified by histology.
Timepoint [2] 320207 0
Final histological verification 14 days after surgery.
Primary outcome [3] 320209 0
Surgeons learning curve, assessed by longitudinal evaluation of the duration of surgery, time of SLB procedure, blood loss.
This data will be collected from the surgery report that is completed by the surgeon after the surgery.
Timepoint [3] 320209 0
2 years of longitudinal evaluation of separate surgeons
Secondary outcome [1] 370860 0
Detection rate of micrometastasis and isoloated tumour cells (ITC) in sentinel lymph nodes, assessed by final histology.
Timepoint [1] 370860 0
FInal histological report including protocol for micrometastasis and ITC up to 3 months after surgery.
Secondary outcome [2] 370861 0
Performance of surgery comparing SLB with pelvic lymphadenectomy and conventional pelvic lymphadenectomy.
The duration of surgery, blood loss, the number of lymphnodes removed will be assessed and compared. This data will be collected from reports of the surgery completed by the surgeon performing operation.
The number of removed lymphnodes will be collected from the final histological report.
It is composite secondary outcome.
Timepoint [2] 370861 0
Duration of surgery and blood loss will be assessed after the surgery and number of removed lymphnodes will be assessed after final histological verification 14 days after the surgery.

Summary
Brief summary
HYPTOHESIS: Sentinel lymph node biopsy (SLB) with Indocyanine green (ICG) mapping is a valuable tool in endometrial cancer patients for pathological staging of the disease which improves short-term and long-term outcomes.

AIM: To determine the value of SLB in endometrial cancer staging and to evaluate short and long - term treatment outcomes.

TASKS:
1. To determine the influence of body mass index (BMI) and uterine or uterine cervix comorbidities on the detection rate of sentinel lymph node mapped with ICG.
2. To evaluate the incidence rate of micro-metastasis and isolated tumour cells (ITC) in SLB and its coherency with local spread of the endometrial cancer.
3. To evaluate the surgeons learning curve in detecting and resecting SLB mapped with ICG.

METHODS:
It is a prospective interventional study that is carried out in Lithuanian University of Health Sciences Hospital, Obstetrics and gynaecology Department.
Inclusion criteria:
- histologically confirmed high risk endometrial carcinoma of the uterus (G 2-3), non-endometrioid carcinoma, carcinosarcoma;
- clinically staged non less than stage I B (FIGO) uterine carcinoma.
Exclusion criteria:
- surgery is done by laparotomy.
For patients undergoing surgical treatment for endometrial cancer - total laparoscopic hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy - indocyanine green dye (ICG) will be used to map sentinel lymph nodes: 1ml of ICG will be injected in 4 points of uterine cervix mucosa and stroma. During laparoscopic surgery in near-infrared light sentinel lymph nodes will be visualised and resected before proceeding with next steps of the surgery - total pelvic lymphadenectomy and hysterectomy.
Sentinel lymph nodes will be examined by pathologist using ultra-staging protocol to find micro-metastasis and isolated tumour cells (ITC).
