The Groningen International Sentinel Lymph Node Study for Vulvar Cancer (GROINSS-V)-II explored whether inguinal femoral lymph node radiotherapy is a safe alternative to inguinal lymph node resection (IFL) for patients with vulvar cancer with sentinel lymph node (SN) metastasis
GROINSS-V-II is a prospective, multi-center, phase 2 single-arm therapeutic trial that included patients with early-stage vulvar cancer (diameter <4 cm).
Cumulative recurrence rate of ipsilateral groin in patients treated with IFL±RT or RT
Cumulative recurrence rate of ipsilateral groin in patients treated with IFL±RT or RTFrom December 2005 to October 2016, a total of 1535 eligible patients were registered, of which 322 (21.
Among the 10 patients with isolated recurrence, 9 had SN metastases> 2 mm and/or extracapsular spread.
The prognosis of the patients in the study cohort: A) disease-specific mortality; (B) overall survival
The prognosis of the patients in the study cohort: A) disease-specific mortality; (B) overall survivalThe researchers modified the treatment plan so that patients with SN large metastases (>2 mm) receive standard care (IFL), while patients with SN micrometastases (≤2 mm) continue to receive inguinal and femoral radiotherapy
Of the 160 patients with SN micrometastases, 126 received inguinal radiotherapy.
Inguinal radiotherapy is a safe alternative therapy for inguinal lymph node dissection in patients with SN micrometastasis, and the treatment-related morbidity is low
