Clinical Research

Along with a committed focus on providing the highest quality of clinical care, our physicians and patients are actively involved in numerous clinical studies both local and nationally. Furthermore, our doctors attend a multidisciplinary cancer conference held twice monthly where we discuss treatments and focus on which patients qualifies for clinical studies available at the cancer center.

The cancer center is unique in that it is the first and only National Cancer Institute (NCI) designated National Community Cancer Center Program in California. This is a high volume, multidisciplinary cancer center focusing on proven NCCN Guideline based treatments.
