Rare Cancers

The Rare Tumor Clinic at UC San Diego Health treats rare cancers, which may be easily misdiagnosed and ineffectively treated by non-specialists.

We work closely with our Center for Personalized Cancer Therapy to provide you with the best in precision medicine.

Nationally Ranked Cancer Care

UC San Diego Health is repeatedly ranked among the nation's best in cancer care by U.S. News & World Report. We are also the only National Cancer Institute (NCI)-designated Comprehensive Cancer Center in San Diego County. This is the highest possible rating for a U.S. cancer center, and it means you’ll receive the best possible care and support. Studies show patient outcomes are better at NCI-designated cancer centers.

Rare Cancers

We treat all types of rare cancers, including:

Cancer of Unknown Primary (CUP)

Cancer of Unknown Primary, also known as CUP, is a rare disease, in which cancer cells are found in the body but it's unclear where they originated.

We offer diagnosis and treatment for CUP cases. Led by Shumei Kato, MD, your care is focused on a precision-medicine approach, with clinical trials matching you to a targeted treatment or immune therapy. 

You may receive multiple types of in-depth diagnostic tests to better understand the origins of your cancer and its biology, including comprehensive genomic and immune profiling, as well as expert pathology review. Your case will also be reviewed by our Molecular Tumor Board.

Personalized Cancer Care

Treatments Tailored to Your Unique Tumor Type

Every person's cancer tumor is unique — this is why we personalize your care plan using molecular profiling of your tumor and genetic testing. When possible, you will receive a genomically targeted treatment and/or immunotherapy. This may be instead of or along with traditional treatments such as surgery or radiation therapy. In addition, an interdisciplinary team of experts meets regularly to review and discuss your care plan.

Clinical Trials

Advancing Cancer Care and Prevention

UC San Diego Health physicians are actively researching ways to improve cancer care. By joining a clinical trial, you may receive a new cancer treatment before it is available to the public. If your cancer has not responded to standard therapies, talk to your doctor about whether a clinical trial could be right for you.

Patient & Family Support Services

At UC San Diego Health, your care goes beyond treating disease. It also includes supporting you and your loved ones emotionally throughout your cancer journey. Most of our support services are free.
