Prostate tumours-TR-colour Doppler evaluation & correlation with PSA & Histo-Pathology
Introduction- The prostate gland is the site of two common diseases in the ageing man, benign prostatic hyperplasia and prostate cancer. Advanced TRUS techniques may help in better tissue characterization, hence in the armamentarium of non- invasive techniques. TRUS provides direct visualisation of echopattern, site and size of lesion and also helps in proper interpretation of focal prostatic lesions.
Material and methods- A Prospective study was conducted in the Dept. of Radio-Diagnosis in 50 patients who were suspected to have prostatic tumours by clinical & TAS examination were subjected TRUS and colour Doppler followed by their histopathological correlation to study the sensitivity and specificity of TRUS and colour Doppler for diagnosis of prostatic tumours.
Results- Majority of the patients 03 out of 07 pts with cancer belonged to the age group of 61- 70 years. Majority of the patients 30 out of 43 (70%) of BPH cases belonged to the age group of 61-80 yrs. At the age of 80 yrs, of BPH patients are found to be 35 0f 43 (81.4%). This study comprised of 50 patients. Among 50 patients diagnosed as prostatic tumours by clinical examination and imaging out of which 07 cases diagnosed as cancer & rest 43 cases to be benign by histopathological examination. TRUS correctly diagnosed 45 patients wrongly diagnosed 05. So TRUS is accurate in diagnosing 90% of prostatic tumours. TRUS with colour Doppler correctly diagnosed 47 patients wrongly diagnosed 05. So it is accurate in diagnosing 94% of prostatic tumours.
Conclusion- TRUS with colour Doppler proves to be a valuable, cost effective and non invasive initial modality of imaging in accurately evaluating the morphologic distribution of prostatic tumours. Technological advances in imaging have created a new role for various tests in the management of prostate cancers. Advances in imaging exploit the biology of the disease, and in doing so, allow more accurate detection of the location, extent, and aggressiveness of the malignancy. In this article, we review the current status of imaging in prostate cancer diagnosis, staging, and the monitoring of recurrence.
