Choosing Watchful Waiting
Watchful waiting involves lifestyle change and careful monitoring for cancer progression. Over the last several years, watchful waiting has evolved into a strategy called “active surveillance” or “delayed surgical intervention.” With this approach, patients have a digital rectal exam and PSA blood test every 6 to 12 months. If test results indicate cancer progression, then treatment options (surgery, radiation, drugs) are considered. Patients should exercise and eat healthy foods. Patients should report symptoms such as weight loss, pain, urinary problems, fatigue, or impotence to their doctors.
Candidates. Watchful waiting may be most appropriate for the following patients:
- Men in their late 70s and older. More aggressive therapies (surgery and radiation) are usually recommended for men in their 50s and younger. The choice for men in their 60s and early 70s is more problematic. The general recommendation is that aggressive therapy is suitable for those who have a life expectancy of more than 10 years and who have localized but mid- to high-grade tumors. The tumor grade may be the best guide for determining the risks in choosing watchful waiting.
- Elderly men with early-stage (T0 to T2) low-grade tumors.
- Men with low-to-moderate (3 - 13 ng/mL) PSA levels.
Some experts think that because prostate cancer grows so slowly, it is likely that older men will die from causes unrelated to the cancer. There is therefore little potential benefit from surgery or radiation, with both posing a risk for impotence and incontinence. However, some recent surveys suggest that more men are choosing treatment (especially surgery) over watchful waiting. The choice is a difficult one. It is important that patients find a doctor who can provide them with all the necessary information so that they can make an informed decision.
Choosing Surgery (Radical Prostatectomy)
In men whose cancer is confined to the prostate, surgical resection (radical prostatectomy) offers the potential for cure. Cure rates from initial surgery in men with localized cancer are about 70%, depending on tumor stage, tumor grade, and PSA levels. Research suggests that surgery provides long-term cancer control. Most patients can consider themselves disease-free if their PSA levels remain undetectable 10 years after surgery.
Candidates. Radical prostatectomy is a consideration for men who meet all of the following criteria:
