Guoping Cai, MD, was intrigued to learn, as a medical student, that pathologists could serve as a bridge between clinical care and basic research. “Pathology is unique in that we are studying the basis of disease,” Dr. Cai says, explaining that he enjoys the challenge of accurately diagnosing diseases from patient biopsies. At Yale Medicine, Dr. Cai specializes in thoracic and genitourinary pathology, as well as cytopathology. For Dr. Cai, medicine is a family affair. He met his wife—then his classmate—at medical school and now his daughter is training to become a physician. 

Much of Dr. Cai’s work focuses on examining genitourinary tract tissue samples and also biopsies of the lung and mediastinum to ensure that cancers and other diseases are accurately diagnosed. In cytopathology, in which a sample of a patient’s cells are examined for disease, he works with all organs, especially the lung and pancreas. 

As an associate professor of pathology at Yale School of Medicine, Dr. Cai investigates how imaging-guided fine-needle aspiration biopsies can be improved with rapid on-site cytological evaluation and ancillary studies. He also works with collaborators on biomarkers of pancreatic, genitourinary and lung cancers, which have diagnostic, prognostic and therapeutic implications.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
