Abstract
Objective: To evaluate the incidence of sentinel lymph node (SLN) metastasis observed in patients with presumed low- and intermediate-risk endometrial cancer (EC) and change in stage and adjuvant therapy resulting from SLN analysis. Secondary objectives include assessing the rates of detection of SLN using indocyanine green (ICG) dye and complication rates.
Methods: Between March 2017 and December 2023, 210 patients were included in the study. A total of 412 SLNs were detected in 210 patients using intracervical ICG dye injections.
Results: The pathologically confirmed detection rate was >95%. A total of 25 (11.9%) patients exhibited positive sentinel metastasis detected through pathological and immunohistochemical analysis, with isolated tumor cell in 5 (2.4%), micro-metastasis in 6 (2.9%), and macro-metastasis in 14 (6.7%) patients. SLN metastasis with micro- and macro-metastases changed to stage III; therefore, adjuvant therapy was administered in the form of chemotherapy and radiation therapy. Of the 210 patients, 186 (88.5%) remained at low and intermediate risk after the final histopathological analysis. The other 24 patients exhibited SLN metastasis, high-grade EC, higher-stage detection, or high risk on molecular profiling.
Conclusion: A change in stage was observed in 11.9% of patients, and adjuvant therapy was administered to 20 patients, of whom 16 received adjuvant therapy based solely on SLN involvement (in the form of micro- and macro-metastasis), thus preventing undertreatment. Overtreatment was reduced in six patients who were classified as high-grade and non-endometrioid types with SLN metastases.
期刊介绍:
Obstetrics & Gynecology Science (NLM title: Obstet Gynecol Sci) is an international peer-review journal that published basic, translational, clinical research, and clinical practice guideline to promote women’s health and prevent obstetric and gynecologic disorders. The journal has an international editorial board and is published in English on the 15th day of every other month. Submitted manuscripts should not contain previously published material and should not be under consideration for publication elsewhere. The journal has been publishing articles since 1958. The aim of the journal is to publish original articles, reviews, case reports, short communications, letters to the editor, and video articles that have the potential to change the practices in women''s health care. The journal’s main focus is the diagnosis, treatment, prediction, and prevention of obstetric and gynecologic disorders. Because the life expectancy of Korean and Asian women is increasing, the journal''s editors are particularly interested in the health of elderly women in these population groups. The journal also publishes articles about reproductive biology, stem cell research, and artificial intelligence research for women; additionally, it provides insights into the physiology and mechanisms of obstetric and gynecologic diseases.
