BACKGROUND: Adjuvant radiotherapy (aRT) has been shown to reduce the risk of local relapse in vulvar cancer (VC). In this multicentre study (OLDLADY-1.2), several Institutions have combined their retrospective data on VC patients to produce a real-world dataset aimed at collecting data on efficacy and safety of aRT.
METHODS: The primary study end-point was the 2-year-local control, secondary end-points were the 2-year-metastasis free-survival, the 2-year-overall survival and the rate and severity of acute and late toxicities. Participating centres were required to fill data sets including age, stage, tumor diameter, type of surgery, margin status, depth of invasion, histology, grading as well technical/dosimetric details of radiotherapy. Data about response, local and regional recurrence, acute and late toxicities, follow-up and outcome measures were also collected.
RESULTS: One hundred eighty-one patients with invasive VC from 9 Institutions were retrospectively identified. The majority of patients were stage III (63%), grade 2 (62.4%) squamous carcinoma (97.2%). Positive nodes were observed in 117 patients (64.6%), moreover tumor diameter > 4 cm, positive/close margins and depth of invasion deeper than 5 mm were found in 59.1%, 38.6%, 58% of patients, respectively. Sixty-one patients (33.7%) received adjuvant chemoradiation, and 120 (66.3%) received radiotherapy alone. aRT was started 3 months after surgery in 50.8% of patients. Prescribed volumes and doses heterogeneity was recorded according to margin status and nodal disease. Overall, 42.5% locoregional recurrences were recorded. With a median follow-up of 27 months (range 1-179), the 2-year actuarial local control rate, metastasis free and overall survival were 68.7%, 84.5%, and 67.5%, respectively. In term of safety, aRT leads to a prevalence of acute skin toxicity with a low incidence of severe toxicities.
CONCLUSIONS: In the context of aRT for VC the present study reports a broad spectrum of approaches which would deserve greater standardization in terms of doses, volumes and drugs used.
