전립선암에서는 2개의 병기시스템이 흔히 사용된다. 대부분의 병원에서 사용되는 병기시스템은 TNM system이다. 그러나 몇몇 병원 및 의사들은 Jewett staging system을 사용하기도 한다. Jewett staging system (Whitmore-Jewett system)은 Whitmore가 1956년에 개발하여 Jewett에 의해 1975년에 변형되어 현재는 수정된 버전을 사용하고 있다. 1997년 미국 암협회(AJCC) 및 국제 암연합(IUAC)는 개정된 TNM system을 채택하였다.
- A :Clinically undetectable tumor confined to the prostate gland and is an incidental finding at prostatic surgery
- A1 :The tumor is well-differentiated with focal involvement and usually left untreated
- A2 :The tumor is moderately or poorly differentiated or involves multiple foci in the gland
- B :The tumor is confined to the prostate gland
- B0 :Non palpable and PSA detected
- B1 :Single nodule in one lobe of the prostate
- B2 :More extensive involvement of one lobe or involvement of both lobes
- C :The tumor clinically localized to the periprostatic area but extending through the prostatic capsule; seminal vesicles may be involved
- C1 :clinical extracapsular extension
- C2 :Extracapsular tumor producing bladder outlet or ureteral obstruction
- D :The tumor has spread to other organs
- D0 :Clinically localized disease (prostate only) but persistently elevated enzymatic serum acid phosphatase titers
- D1 :Regional lymph nodes only
- D2 :Distant lymph nodes and metastasis to bone or visceral organs
- D3 :D2 prostate cancer patients who relapsed after adequate endocrine therapy
