Feasibility Study of Sentinel Navigation Surgery in Early Gastric Cancer Using Fluorescence (SENORITA4)
- Conditions
- Early Gastric Cancer
- Interventions
- Procedure: Laparoscopic sentinel navigation surgery using fluorescence
- Registration Number
- NCT05978882
- Lead Sponsor
- National Cancer Center, Korea
- Brief Summary
SENORITA 1 trial showed laparoscopic sentinel lymph node biopsy and stomach preserving surgery in early gastric cancer can increase the quality of life. (Ryu KW et al. JCO 2022) The radioactive isotope is difficult to use because of the hazard of radiation and shortage of materials. The aim of this study is to investigate whether laparoscopic sentinel lymph node biopsy and stomach-preserving surgery using only fluorescence is feasible.
- Detailed Description
1. Injection of Indocyanine Green (ICG)
* Endoscopic injection of 0.25mg/ml of ICG on 4 sites around gastric cancer
* Identification of sentinel basin using fluorescence laparoscopy
* Laparoscopic sentinel basin dissection and identification of sentinel node at the back table
2. Surgical considerations
* Conventional gastrectomy is performed if positive sentinel nodes are diagnosed in the frozen section.
* If micrometastasis or isolated tumor cells in sentinel basin lymph nodes were diagnosed in permanent pathology, re-operation of conventional gastrectomy is not performed.
* However, re-operation of conventional gastrectomy should be performed in case of macrometastasis, deep and lateral margin positive, more than pT2 lesion in the permanent pathology.

- Arm && Interventions
Group Intervention Description Laparoscopic sentinel navigation surgery Laparoscopic sentinel navigation surgery using fluorescence compare the detection rate of sentinel lymph nodes to that of previous study (SENORITA1 trial)
- Primary Outcome Measures
Name Time Method Detection rate of Sentinel lymph nodes 15 days after operation number of patients whose sentinel nodes are detected / enrolled number of patients \*100
- Secondary Outcome Measures
Name Time Method 3 year overall survival rate 3 year after surgery A total of enrollment period is suspected to be three years and patients will be followed up for five years.
3 year recurrence free survival rate 3 year after surgery A total of enrollment period is suspected to be three years and patients will be followed up for five years.
scores of global health status scale, functional scales, and symptom scales/items of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30 and STO22 5 years Survey for quality of life will be performed regularly for three years after surgery. Measurement tool is the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30 and STO22. In EORTC QLQ C30, there are 1 global health status scale, 5 functional scales, and 9 symptom scales/items. EORTC QLQ STO22 includes 5 symptom scales and 4 single items. Each scale and item ranges 0 to 100. Higher score of global health status and functinoal scales indicate better quality of life and lower score of symptom scales indicates better quality of life. There is no summed score in these questionnaires.
5 year disease specific death rate 5 years A total of enrollment period is suspected to be three years and patients will be followed up for five years. Therefore, we can complete data collection at five year later from when the last enrolled patients underwent intervention
3 year disease free survival 3 year after surgery A total of enrollment period is suspected to be three years and patients will be followed up for five years.
