Prostate Cancer Flashcards
What is prostate cancer?
Prostate cancer is a malignancy originating in the prostate gland, commonly affecting men worldwide.
How prevalent is prostate cancer in the UK?
Approximately 48,500 new cases are diagnosed annually, representing 25% of all new male cancer cases.
What is the 5-year survival rate for prostate cancer?
The 5-year survival rate is approximately 98%, indicating a highly curable condition.
What are common risk factors for prostate cancer?
Risk factors include advancing age, family history, African-Caribbean ethnicity, and a diet high in saturated fats.
What are typical symptoms of prostate cancer?
Early stages may be asymptomatic; later stages can present with lower urinary tract symptoms (LUTS) such as hesitancy, weak stream, nocturia, and haematuria.
What is the role of prostate-specific antigen (PSA) in prostate cancer?
PSA is a protein produced by the prostate; elevated levels can indicate prostate cancer but may also be due to benign conditions.
How is prostate cancer diagnosed?
Diagnosis involves a combination of PSA testing, digital rectal examination (DRE), and prostate biopsy.
What imaging modalities are used in prostate cancer evaluation?
Multiparametric MRI is commonly used for staging and assessing the extent of the disease.
What is the Gleason scoring system?
A grading system that assesses the aggressiveness of prostate cancer based on histological appearance, ranging from 6 (least aggressive) to 10 (most aggressive).
What are the main treatment options for localized prostate cancer?
Options include active surveillance, radical prostatectomy, and radiotherapy.
What is active surveillance in prostate cancer management?
A monitoring approach for low-risk, localized prostate cancer involving regular PSA tests, DREs, and repeat biopsies to avoid overtreatment.
What is a radical prostatectomy?
A surgical procedure involving the complete removal of the prostate gland and seminal vesicles to treat localized prostate cancer.
What are potential side effects of radical prostatectomy?
Side effects can include urinary incontinence and erectile dysfunction.
How does radiotherapy treat prostate cancer?
Radiotherapy uses high-energy radiation to destroy cancer cells in the prostate, suitable for localized or locally advanced disease.
What is androgen deprivation therapy (ADT)?
A treatment that reduces androgen levels to slow the growth of prostate cancer, used in advanced or metastatic cases.
