Phase II activity trial of high-dose radiation and chemosensitization in patients with macrometastatic lymph node spread after sentinel node biopsy in vulvar cancer: GROningen INternational Study on Sentinel nodes in Vulvar cancer III (GROINSS-V III/NRG-GY024)
Bibliographic record
Abstract
BACKGROUND: 2 mm). When there is macrometastasis (>2 mm) in the SLN, an inguinofemoral lymphadenectomy is indicated; however, this procedure is associated with major morbidity, such as wound healing, lymphoceles, and lymphedema. PRIMARY OBJECTIVE: To investigate the safety of replacing inguinofemoral lymphadenectomy by chemoradiation in patients with early-stage vulvar cancer with a macrometastasis (>2 mm) and/or extracapsular extension in the sentinel node. STUDY HYPOTHESIS: Combination of 56 Gy of radiation to the inguinal site and concurrent cisplatin chemotherapy without completion inguinofemoral lymphadenectomy will be feasible and safe, with low groin recurrence rates. TRIAL DESIGN: This is a single-arm, prospective phase II treatment trial with stopping rules for unacceptable groin recurrences. Eligible patients will receive 56 Gy of radiation to the involved inguinal site and chemotherapy with concurrent cisplatin. MAJOR INCLUSION/EXCLUSION CRITERIA: Eligible patients undergoing sentinel node procedure will have stage I, unifocal, invasive (>1 mm depth of invasion) squamous cell carcinoma of the vulva with tumor size <4 cm, and no suspicious nodes on imaging. Those eligible for the trial are those with a metastasis >2 mm in the sentinel node and/or extracapsular extension, or more than one sentinel node with micrometastasis ≤2 mm. PRIMARY ENDPOINT: Groin recurrence rate in the first 2 years after primary treatment. SAMPLE SIZE: 157 patients with macrometastases in their SLN. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: January 1, 2029. TRIAL REGISTRATION NUMBER: NCT05076942.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
