In vulvar cancer patients with a macrometastasis in the sentinel lymph nodes, chemoradiation is as effective as an inguinofemoral lymphadenectomy, but is associated with less treatment-related morbidity.

Groin recurrence rate in the first two years after primary treatment.
Achtergrond van het onderzoek
Standard treatment of early stage vulvar cancer is a wide local excision of the primary tumor combined with the sentinel node (SN) procedure for the groins. An inguinofemoral lymphadenectomy (IFL) is only indicated in patients with a positive SN. An IFL is associated with major morbidity, e.g. wound healing problems, lymphoceles, lymphedema of the legs and recurrent infections. GROINSS-V II investigated whether radiotherapy would be a safe alternative for IFL in patients with metastasis in their SN. The results for radiotherapy in the group with metastasis ≤ 2mm are promising. This study also showed that for patients with metastasis > 2mm, only radiotherapy was not efficient. The efficacy of treatment can be increased by adding chemotherapy or giving a higher dose of radiotherapy. In GROINSS-V III we will investigate this regimen.
Doel van het onderzoek
In vulvar cancer patients with a macrometastasis in the sentinel lymph nodes, chemoradiation is as effective as an inguinofemoral lymphadenectomy, but is associated with less treatment-related morbidity.
Onderzoeksopzet
After primary treatment, patients will be followed-up 3-monthly for two years. Groin recurrence rate will be monitored continuously with stopping rules for the occurence of groin recurrences.
QOL will be evaluated at 6, 12, 18 and 24 months after primary treatment.
Onderzoeksproduct en/of interventie
Patients will be treated with chemoradiation, in a total dose of 56Gy to the involved site, combined with weekly cisplatin 40mg/m2
