Read more on Symptoms, Diagnosis and Treatment.

Early state (organ confined) and is asymptomatic


 - LOCALLY ADVANCED


Obstructive voiding symptoms, Hesitancy, Intermittent urinary stream, Decreased force of stream, May have growth into the urethra or bladder neck , Hematuria , Hematospermia . Advanced (spread to the regional pelvic lymph nodes), Edema of the lower extremities and pelvic and perineal discomfort.



- CLINICAL MANIFESTATIONS OF METASTASIS


Most commonly to bone (frequently asymptomatic) can cause severe and unremitting pain. Bone metastasis can result in pathologic fractures or Spinal cord compression. Visceral metastases (rare) can develop pulmonary, hepatic, pleural, peritoneal and central nervous system metastases late in the natural history or after hormonal therapies fail.



DETECTION AND DIAGNOSIS


PSA level is helpful in asymptomatic patients and more than > 60% of patients with prostate cancer are asymptomatic. Diagnosis is made solely because of an elevated screening PSA level. A palpable nodule on digital rectal examination is next most common clinical presentation and prompts biopsy. Much less commonly, patients are symptomatic. In advanced disease cases patients manifest with Obstructive voiding symptoms, Pelvic or perineal discomfort, Lower extremity edema and symptomatic bone lesions.


A digital rectal examination is of low sensitivity and specificity for diagnosis. However, a biopsy of a nodule or area of induration reveals cancer 50% of the time and that suggests that prostate biopsy should be undertaken in all men with palpable nodules.


The PSA level a better sensitivity but a low specificity, it indicates Benign prostatic hypertrophy and prostatitis . The PSA Velocity is a better measure of high risk patients. A rate >0.75/year increase warrants biopsy.



TREATMENT


          Surgery




  1. Traditional

  2. RoboticRadiation



  1. Brachytherapy

  2. External beam

    • Cryotherapy

    • Androgen Deprivation
