NCT04147780

Brief Summary

The aim of this study is to investigate the feasibility of sentinel node biopsy in patients with squamous cell vulvar cancer, currently not regarded suitable for the sentinel node technique, i.e. patients with tumors ≥4cm, multifocal tumors or locally recurrent disease. A positive result of this pilot study might constitute the basis for a future full-scale multinational trial.

Outcome Measures

Primary Outcomes (1)

  • Detection rate and negative predictive value for sentinel node biopsy

    Calculated for each group separately. Per groin and per patient.

    2019-2021

Secondary Outcomes (2)

  • Number of retrieved sentinel lymph nodes

    2019-2021

  • Proportion of micrometastases and isolated tumor cells, diagnosed by ultra-staging in relation to routine-histopathological examination

    2019-2021

Study Arms (4)

Primary vulvar cancer, tumor ≥ 4cm

Patients with primary squamous cell vulvar cancer, unifocal tumor ≥ 4cm: Sentinel node biopsy additional to radical inguinofemoral lymphadenectomy

Procedure: Sentinel node biopsy

Primary vulvar cancer, multifocal tumor

Patients with primary squamous cell vulvar cancer, multifocal tumor: Sentinel node biopsy additional to radical inguinofemoral lymphadenectomy

Procedure: Sentinel node biopsy

Local recurrence after vulvar cancer, no earlier treatment

Patients with a local recurrence of a primary squamous cell vulvar cancer, earlier without treatment of the groins or solely sentinel node biopsy: Sentinel node biopsy additional to radical inguinofemoral lymphadenectomy

Procedure: Sentinel node biopsy

Local recurrence after vulvar cancer, earlier treatment

Patients with a local recurrence of a primary squamous cell vulvar cancer, earlier treatment of the groins by lymphadenectomy and / or (chemo-)radiation: Sentinel node biopsy if detectable, otherwise no groin treatment

Procedure: Sentinel node biopsy

Interventions

Sentinel node biopsy, radiotracer (mandatory) and blye dye (optional). Scintigraphy.

Local recurrence after vulvar cancer, earlier treatmentLocal recurrence after vulvar cancer, no earlier treatmentPrimary vulvar cancer, multifocal tumorPrimary vulvar cancer, tumor ≥ 4cm
