Serum VEGF-C is associated with metastatic site in patients with malignant melanoma

Zusammenfassung: | Vascular endothelial growth factor-C (VEGF-C) is involved in lymphatic metastatic spread. Metastatic site is a prognostic factor in melanoma. We assessed whether serum levels of VEGF-C are associated with metastatic sites or prognosis in patients treated for stage IV melanoma. The study included 64 patients, who received dacarbazine or four-drug chemotherapy (dacarbazine, vincristine, bleomycin and lomustine; BOLD) both combined with interferon-alfa. Serum samples for VEGF-C were analyzed by ELISA. The patients (n =22) with only skin and subcutaneous metastases had significantly lower mean VEGF-C levels (1 643 pg/ml) then the patients (n =42) with other distant metastases (2 584 pg/ml, Mann-Whitney, p =0.033). VEGF-C levels above the median (1 590 pg/ml) were significantly related to deep lymph node involvement (OR 3.763; 95% CI 1.038 − 13.646, p =0.034). There were no other significant associations between VEGF-C levels and tumour burden, nor were the levels significantly related to the response to therapy or survival. Those eight patients, who had received previous adjuvant IFN-alfa therapy had lower mean VEGF-C levels (1 738 pg/ml) as compared to those 56 patients without previous IFN-alfa therapy (2 335 pg/ml, ANOVA, p =0.026). This is the first study exploring serum VEGF-C in melanoma. VEGF-C might be involved in the deep lymphatic dissemination and progression of melanoma metastasis. |
