About me

Dr. John de Groot is a neuro-oncologist who specializes in diagnosing and managing the care of patients with primary brain and spine tumors (those at the site where disease began, as compared with tumors that result from the disease spreading).

De Groot has brought new therapies from the laboratory into the clinic to treat patients with brain cancer. In particular, he has contributed to the development of glioblastoma treatments. He has a special interest in using blood analyses, imaging studies and other indirect biomarkers (measurable elements that may indicate disease) to evaluate the efficacy of novel therapies. In one study, he is looking at ways to overcome physiological limitations in drug delivery to brain tumors, such as through focused ultrasound. He regularly advises and collaborates with other researchers on promising therapies under development.

De Groot earned his medical degree from the University of Texas Medical Branch at Galveston. He completed a residency in neurology at Johns Hopkins University and a fellowship in neuro-oncology at the University of Texas MD Anderson Cancer Center.

    Would have like to understand clearly what the purpose of the appointment was. I felt I didn't get much from the meeting.

    I was unaware of an increase in the chemo dosage from 250 mg to 360 mg per day. No mention was made of that possibility at our appointment even though I confirmed the dosage of 240 mg specifically. I found out of the increase when I called the UCSF pharmacy to check on the prescription. The pharmacist confirmed the increase with the oncology team fir me and made sure a note was sent to the external pharmacy handling the medication dispense just to make sure there weren't back and forth delays caused by the increase.

    I had a problem getting a prescription I needed which was the reason for my visit. I would have been better off going to outside urgent care.

    We were profoundly moved by the degree of heartfelt listening and compassion rendered by Dr. DeGroot. I have never experienced this degree of compassion from a medical person. We hope this message gets to him.
