Before joining an ovarian cancer clinical trial, ask what the study is meant to learn, how it compares with your other care options, what participation will involve, and what costs or risks you may face. Enrollment is voluntary; a trial is one possible care option, not a promise of personal benefit. Bring a support person if you wish, take notes, and ask the oncologist and study coordinator to explain anything that is unclear. The study team and consent form are the authorities on the details of a particular protocol.
What is the trial trying to answer, and what are my alternatives?
Start by asking the study team to describe the trial’s main purpose in plain language. A study may test a treatment, focus on symptoms or quality of life, or assess safety. Ask why researchers think the study approach might help, what remains unknown, and how its possible benefits and risks compare with standard care.

- What is the purpose of this trial, and what outcome are researchers measuring?
- What are my standard-care options and other choices, including not joining?
- Is there time to discuss these options with my regular oncologist or seek another opinion?
A treatment trial may not be better than standard treatment and can involve additional procedures or expenses. NCI’s questions to ask about clinical trials include the study’s purpose and comparison with standard treatment.

Do I meet this protocol’s eligibility criteria?
Eligibility can depend on the exact cancer diagnosis and stage, histology, prior treatment, tumor or inherited genetic findings, age, medical history, and current health. Ovarian cancer studies may include epithelial ovarian, fallopian tube, or primary peritoneal cancers, while others may address supportive or palliative care rather than treating the cancer itself.
#1 Best Overall
- Which specific diagnosis and patient group does this study include?
- Which details in my records are uncertain, and what tests or records are needed to determine eligibility?
- If I am not eligible, can you explain why and discuss other trials or care options that may fit?
A trial listing is not a determination that you are eligible or that the study is suitable for you. The study team must review the protocol’s criteria and your medical information. NCI explains factors that can affect eligibility in its guidance on clinical trial eligibility.
What treatment could I receive, and what are the risks?
Ask which treatment or comparison group you could receive and how assignment works. Some studies assign participants randomly; some may blind participants or clinicians to which treatment is given. These features depend on the protocol.
Rank #2
- Is assignment random? Is any part of the study blinded?
- What side effects are known, what serious harms are possible, and what is still uncertain?
- How will the team check whether the treatment is helping or causing harm?
- Which symptoms should prompt a call, and who can I reach after hours?
- What happens if the cancer worsens, I have a serious problem, or I want to stop?
- If the study ends or treatment appears to help, what follow-up or treatment might be available afterward?
Monitoring does not remove treatment risks or guarantee that a study treatment will help. NCI notes that a trial treatment may not be better than standard treatment and may cause more serious side effects; the risks depend on the intervention and protocol. See NCI’s explanation of clinical trials.

How will participation affect visits and daily life?
Get a practical picture of the full schedule, including any follow-up after treatment or after you leave the study. Ask which requirements go beyond your usual care.
- How long might I be in the study, and how often will I need to visit?
- Which blood tests, scans, biopsies, procedures, questionnaires, or hospital stays are required?
- Can any visits be local or remote? How far will I travel, and how much time should I plan for each visit?
- Could the schedule affect work, caregiving, travel, or other daily activities?
- What follow-up continues after treatment or if I leave the trial?
Visit frequency and procedures vary by protocol. NCI’s clinical trial question guide identifies time, tests, hospital stays, travel, daily activities, and follow-up as topics to discuss.
What does the consent form say, and can I change my mind?
Informed consent is a discussion and decision process, not just a signature. Ask the coordinator or clinician to review the form with you in language you understand. You can ask to take it home and have time to consider it before deciding.
Rank #4
- What information will be collected, who can see it, and how will my medical information be protected?
- What responsibilities would I have as a participant, and whom can I contact with concerns?
- How will the team tell me about important new safety information or study results?
- If I decide not to join, or later choose to leave, what steps should I take and what care will continue?
Participation is voluntary. Amy Rose, associate director in Clinical Research Services at UPMC Hillman Cancer Center, told NCI: “You do not have to continue just because you sign this consent today.” Read NCI’s overview of informed consent for clinical trials.

Which costs and support should I confirm?
Do not assume that all study-related care, insurance, or travel expenses are covered. Ask the study team to separate costs paid by the study from those that could be billed to insurance or to you, then check coverage directly with your insurer.

If you are weighing more than one study or comparing a trial with standard care, make the comparison around what matters for your cancer and circumstances. Your oncology team can help interpret the options; the factors below are not a way to rank trials without individualized clinical advice.
| Compare | What to clarify |
|---|---|
| Goal and approach | What the study aims to learn, what treatment it uses, and what is known or uncertain about it |
| Eligibility fit | Whether your diagnosis, treatment history, test results, and health meet that protocol’s criteria |
| Potential benefit and risk | How benefit will be assessed, known and uncertain harms, and any comparison group or random assignment |
| Practical burden | Visits, procedures, location, travel, time, and follow-up |
| Costs and support | Which expenses may be covered, what could be billed to you, and whether participant support is available |
| Other paths | What care is available if you do not enroll or if you leave the study later |
Study status, recruitment, eligibility, treatment arms, and locations can change. Confirm current details with the research team and relevant registry, and discuss treatment decisions with your treating oncologist. NCI’s guidance is U.S.-focused; readers elsewhere should also consult their national cancer and research systems.
