Abstract
The significance of neoangiogenesis in the metastasis of nasopharyngeal carcinoma (NPC) was investigated to clarify the role neovascularity in the prognosis of NPC and the probability of antiangiogenesis preventing NPC from distant metastasis. A group of 52 patients presenting with metastatic NPC were selected and strictly paired one-to-one, in sex, age, T stage, and N stage, with another 52 patients with non-metastatic NPC, who had survived for a long time after therapy. The tumor tissues of all 104 patients were retrieved for computer-assisted, immunohistochemical analysis of tumor vasculature. Counts of the microvessels and the relative area of all microvessels per image were significantly higher in metastatic NPC than they were in curable, non-metastatic NPC, while the average area of the microvessels and their average perimeter of in metastatic NPC were smaller than in non-metastatic disease. No significant difference in any microvessel parameter was found among the various types of metastasis. The alterations of microvessel parameters were significantly linked to the metastasis of NPC. Evaluation of neovascularity by computer image analysis may be helpful in estimating the prognosis of NPC and in determining the indicators for aggressive multimodal treatments.
