RESEARCH SUMMARY

Laboratory of Molecular Radiotherapy Mission:

To design, engineer, and test targeted drugs to diagnose and treat people with cancer

On Radiopharmaceutical Therapy:

Advances in engineering of tumor-specific molecules to guide cytotoxic treatments, such as chemotherapy or radionuclides, have resulted in new classes of cancer drugs which have the potential to kill tumors while mitigating toxicities to normal tissues, moving us closer to truly tumor-targeted, personalized cancer treatment for our patients.  Targeted radionuclide therapy provides an orthogonal mode of cell killing that is distinct from, yet complementary to, existing small molecule and chemotherapy treatments. By harnessing systemic, targeted radionuclides, our group aims to develop new agents to help us better treat and monitor cancer patients.

Clinical:

Dr. Escorcia is also a board-certified attending radiation oncologist within the Radiation Oncology Branch and treats patients with all tumor types amenable to radiation therapy, including gastrointestinal and hepatobiliary malignancies.  He is fluent in Spanish and English.
