Total Microvessel Perimeter Per Tumor Area Is a Predictor of Radiosensitivity in Early-Stage Glottic Carcinoma

Assessment of TP/TA in biopsy specimens, using a computer-assisted analysis system, can predict the radiosensitivity of early-stage glottic carcinoma. High TP/TA may be a better indication for radiotherapy than for partial laryngectomy or laser excision.
