Summary
For early vulvar cancer, wide excision is recommended for tumors <1mm thick. Sentinel lymph node examination is a valuable tool, but selective lymphadenectomy requires further research.
Area of Science:
- Gynecologic Oncology
- Surgical Oncology
Context:
- Primary vulvar cancer treatment has historically involved radical vulvectomy.
- There is a need for less mutilating surgical approaches without compromising patient prognosis.
Purpose:
- To review surgical management and sentinel lymph node examination for early-stage vulvar cancer.
- To provide evidence-based recommendations for surgical treatment based on tumor characteristics.
Summary:
- Tumors less than 1 mm thick rarely metastasize to regional lymph nodes and can be treated with wide excision alone.
- For T1 lesions with deeper invasion, radical excision with 2 cm margins is recommended, along with complete inguinal-femoral lymphadenectomy.
- Sentinel lymph node biopsy using 99mTechnetium and patent blue dye is a valuable tool for identifying metastatic nodes and guiding surgical extent.
Impact:
- This review guides surgical decision-making in early vulvar cancer, potentially reducing surgical morbidity.
- It emphasizes tailored treatment strategies based on tumor depth and size, improving outcomes.
- Highlights the role of sentinel lymph node biopsy in accurate staging and treatment planning.
