Clinical trials: A significant part of cancer care

"Often, when patients are diagnosed with cancer, they feel hopeless and scared. Clinical trials are one way patients can be proactive. They can make a choice in how their care is going to be," says Matthew Block, M.D., Ph.D., a Mayo Clinic medical oncologist.

Cancer clinical trials help physician-scientists test new and better ways to control and treat cancer. During a clinical trial, participants receive specific interventions, and researchers determine if those interventions are safe and effective. Interventions studied in clinical trials might be new cancer drugs or new combinations of drugs, new medical procedures, new surgical techniques or devices, new ways to use existing treatments, and lifestyle or behavior changes.

You will receive cancer treatment if you participate in a clinical trial. "I think one common misperception about clinical trials is that if you enter a clinical trial, you may not get treatment (receive a placebo). And that's actually very much not true. Most clinical trials are looking at one treatment compared to another treatment," says Judy C. Boughey, M.D., a Mayo Clinic surgical oncologist, chair of Breast and Melanoma Surgical Oncology at Mayo Clinic in Rochester, Minnesota, and chair of the Mayo Clinic Comprehensive Cancer Center Breast Cancer Disease Group.

If you choose to participate in a clinical trial, you will continue to receive cancer care. "For most patients that we evaluate, there's always the standard of care treatment option for those patients. And then, in many situations, there's also a clinical trial that the patient can participate in," says Dr. Boughey.

"We couldn't advance medicine if it wasn't for people volunteering for trials. And the promise from our side is to say we're not going to put patients on trials or offer trials for them to consider unless we think there's a good chance that they'll get a benefit or that society at large will get a benefit," says Geoffrey Johnson, M.D., Ph.D., a Mayo Clinic radiologist, nuclear medicine specialist and co-chair of the Mayo Clinic Comprehensive Cancer Center Experimental and Novel Therapeutics Disease Group.

"And remember, you can ask this of your surgical oncologist, your medical oncologist, your radiation oncologist, or any of the physicians you're seeing because there are trials in all disciplines," says Dr. Boughey.
