Evaluation of angiogenesis as a prognostic marker in prostatic neoplasm especially carcinoma of prostate

摘要

Background: Prostatic carcinoma shows an unusually wide range of biological potential with well-known disparity between incidence and mortality for disease. Clinico-pathological studies suggests that angiogenesis and tumor neovascularity contributes to pathogenesis of prostate cancer. The aim of this study to present study was done to assess the validity of angiogenesis as a suitable prognostic marker in various prostatic disease specially the neoplasm’s including the malignant ones. Settings and design are Retrospective study. Methods: The present study of evaluation of angiogenesis as a prognostic marker in prostatic neoplasm especially carcinoma of prostate was done with 40 biopsy sample. The biopsy sample were obtained by suprapubic prostatectomy specimen and trans rectal needle biopsy specimen. Tissue sections were subjected to routine H and E staining. For demonstration of angiogenesis staining for reticulin fibers was applied. Results: The microvessels density increases as the severity of lesion increases from benign to pre-neoplastic to frankly malignant. The micro vessel density in malignant lesions is approximately thrice that in benign lesions. Conclusions: Very few studies have been done in prostatic lesions Hence an attempt is made to demonstrate and correlate angiogenesis as a tumour marker.
