Special Issue Information

Dear Colleagues,

Sentinel lymph node (SLN) mapping has revolutionized the assessment and management of gynecological cancer by providing crucial prognostic information while minimizing treatment-related morbidity. SLN biopsy has transformed the traditional lymph node evaluation paradigm for early stage vulvar, cervical, and endometrial cancers, where nodal status carries significant prognostic implications. With the goal of removing the primary tumor and accurately staging regional lymph nodes, SLN biopsy offers a promising alternative to extensive lymphadenectomies, which are often associated with substantial morbidity.

For vulvar cancer, level 3 evidence supports the safety of omitting inguinofemoral lymphadenectomy when the sentinel node is negative.

Similarly, for clinical early stage endometrial and cervical cancer, acceptable false-negative rates have been observed, indicating the potential clinical utility and safety of SLN biopsy. But despite its potential in these malignancies, SLN biopsy alone has yet to attain gold-standard status due to the lack of prospective evidence on long-term oncological safety. Ongoing prospective trials are expected to shed light on these unresolved issues, providing crucial insights into the efficacy and safety of SLN biopsy.

SLN is not yet an established and widely accepted procedure in ovarian cancer, and evidence of SLN in early EOC is still scarce. Emerging techniques utilizing infundibulopelvic and proper ovarian ligament injections show promise for successful SLN detection during minimally invasive surgeries.

Sentinel lymph node mapping holds immense potential in gynecological cancer care, offering precision staging with reduced morbidity. As ongoing trials continue to investigate its long-term oncological safety, we anticipate that SLN mapping will become an integral component of the standard of care, improving outcomes and enhancing the quality of life for women facing gynecological malignancies.

(1) Background: Sentinel lymph node (SLN) mapping represents an accurate and feasible technique for the surgical staging of endometrial and cervical cancer. This is commonly performed by conventional laparoscopy or robotic-assisted laparoscopy, but in recent years, a new retroperitoneal transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach has been described and developed by Jan Baekelandt. This technique provides easy visualization of lymphatic afferent vessels and pelvic lymph nodes, early SLN assessment, and a coherent mapping methodology following the lymphatic flow from caudal to cranial. However, only a few publications have reported it. Following the IDEAL (Idea Development Exploration Assessment Long-term follow-up) framework, research concerning this technique is in Stage 2a, with only small case series as evidence of its feasibility. Its standardized description appears necessary to provide the surgical homogeneity required to move further. (2) Methods: Description of a standardized approach for retroperitoneal pelvic SLN mapping by vNOTES. (3) Results: We describe a 10-step approach to successfully perform retroperitoneal vNOTES SLN mapping, including pre-, intra-, and postoperative management. (4) Conclusions: This IDEAL Stage 2a study could help other surgeons approach this new technique, and it proposes a common methodology necessary for evolving through future IDEAL Stage 2b (multi-center studies) and Stage 3 (randomized controlled trials) studies.
