Philosophy of Care

I firmly believe that my patients, particularly those with cancer, are best managed with a multidisciplinary team approach and that patients, along with their family members, are integral to the decision-making process. I feel extremely fortunate to be a part of our National Cancer Institute-Designated Comprehensive Cancer Center, and to work alongside the dedicated physicians, nurses and other affiliated personnel who make it possible for our patients to have some of the very best care available anywhere in the world. In addition to offering state-of-the-art care and clinical research trials, we have the unique opportunity to discuss patients with lung cancer and other thoracic malignancies before an expert panel of sub-specialists at our "Thoracic Tumor Board." Whether it is to diagnose, treat or palliate lung cancer, it is through our tumor board, or through close consultation with my medical oncology, thoracic surgery, radiation oncology, and thoracic radiology colleagues, that I am able to devise the best strategies for my patients. I know care must be individualized, as no single strategy works for all patients. Perhaps more so than for any other disease, a cancer patient's overall condition, as well as their desires and expectations, play the most important role in this decision-making process.

As an Interventional Pulmonologist, I also care for patients with non-malignant pulmonary disorders including severe persistent asthma, chronic obstructive pulmonary disease (COPD), non-malignant pleural effusions and benign airway strictures that may require advanced diagnostic or therapeutic procedures, normally offered only at tertiary centers such as UC Davis. Again, I feel honored to work with a dedicated group of Interventional Pulmonologists and a highly skilled and compassionate group of nurses and respiratory therapists in our Interventional Pulmonology Laboratory. 

Clinical Interests

Dr. Yoneda's primary outpatient clinical interests are in the diagnosis, staging, and palliation of lung cancer and the thoracic complications associated with lung cancer. In addition, as an Interventional Pulmonologist, he is involved in the treatment of severe persistent asthma, severe emphysema, airway stenosis, and pleural effusions, employing innovative and complex techniques to treat these pulmonary disorders. It is his belief that technological advances in these fields have improved patient comfort and safety while improving outcomes and reducing the length of hospitalizations. While a variety of procedural approaches are available, he believes that no single strategy works for all patients, and care must be individualized. 

Research/Academic Interests

Dr. Yoneda's clinical research is focused on lung cancer, particularly with regard to the role of interventional pulmonology in the diagnosis, management, and palliation of lung cancer, and the development of interstitial lung disease in lung cancer patients. He also conducts clinical trials in chronic obstructive pulmonary disease (COPD) and asthma. His basic-science research has involved the study of alterations in airway epithelial cells exposed to tobacco smoke and on differential gene expression in lung cancer.
