If you choose active surveillance, a PSA test will be performed every three months in the first two years and every six months thereafter. These visits are called laboratory (lab) visits and you will not have direct contact with your physician. At 6, 12, 18 and 24 months, and annually thereafter evaluation visits will be scheduled. This means you will then visit your physician. Please find the time schedule on the next page. At the evaluation visits, not only a PSA test is performed, but a physical examination is performed as well. The physical examination includes a digital rectal examination. Additionally, after 1, 4, 7 and 10 years, and every five years thereafter a repeat biopsy is scheduled. You physician will explain and evaluate all parameters and will advise you what to do. If the situation is stable he will advise you to continue on active surveillance; otherwise deferred treatment is advised.

Years in which no standard biopsy is scheduled (table 1), a situation can occur in which the PSA-test and the physical examination will not provide the physician with enough information. In these circumstances, an additional repeat biopsy may be advised. Supported by the additional information from the biopsy, your physician can then provide you with a well informed advice about your prostate cancer.


If you decide not to participate in this project, you will receive standard care. Please note that this decision will not have any consequences for the quality of care you will receive. Alternative options can be discussed with your physician.

There are no extra costs associated with this research project. Furthermore will you not receive a fee for participation. The follow-up schedule for active surveillance is very similar to that after treatment, so the only additional time commitment of this study is the extra biopsies, but there are overall time savings for you because treatment is avoided or delayed.

Your personal information, which will be gathered for the study can only be accessed by a limited number of persons, and only after you have given a written consent for it. These persons are members of the research team, the medical inspection and members of the ethical board. Access can be necessary to study the quality and reliability of the research project. The law on protection of personal information and the privacy rules of the hospital will be obeyed.

A unique identification number will substitute personal information. Only that number will be used in analyses and scientific publications. Only those who know which number corresponds to which patient (the study physicians data managers and your physician) can make the link to you as a person. The data will be stored for 15 years after the research project has ended, but only if you give consent for it.

The board of directors of your hospital has approved this research project after the ethical board has studied and approved it. The international guidelines for this type of research will be obeyed carefully.

Participation in this project is completely voluntarily. If you do not want to participate, you do not have to explain why. If you give us your consent, but after reconsideration decide that you do not want to participate anymore, it is possible to withdraw your consent at any time, without giving a reason. The research project will be executed by its initial plan, although there are circumstances in which we feel it is necessary to change the initial plan. In that case, modifications will be discussed with you; so you can decide whether you still want to participate. If your personal safety is in danger, your physician will end your participation to this project.
