From: Prediction of melanoma metastasis by the Shields index based on lymphatic vessel density
Mean epi-tumoural lymphatic vessel density and lymphatic vessel invasion. Lymphatic vessel density was significantly higher in tumours from patients that subsequently developed metastases (metastatic), compared to non-metastatic tumours (p < 0.0001, unpaired t test). B) There were a greater percentage of tumours with signs of LVI in the metastatic patient group compared to the non-metastatic group (p < 0.001 Fisher's Exact Test). C) Shields Index values were calculated by combining peritumoural LD, LVI and Breslow thickness. Mean Shields Index value was significantly higher in patients that subsequently developed metastases (metastatic), compared to non-metastatic tumours (p < 0.0001, unpaired t test). Error bars represent standard error of the mean
