Interview Podcast: Dr. Eric Vallières on Pre-Operative Work-Up and Surgery for Lung Cancer

Article

I'm very happy to present an audio interview with Dr. Eric Vallières, an excellent thoracic surgeon and Surgical Director of the Lung Cancer Program at Swedish Cancer Institute. Within the lung cancer community, he actually happens to be among the most well known thoracic surgeons in the country and even world, and he has a major expertise in the integration of chemotherapy and other systemic therapies for early stage lung cancer.

PET Scans for Follow-up of Patients After Surgery or Chemo/Radiation

Article

We know PET scans can provide additional metabolic information that can be more sensitive and specific for cancer than chest x-rays and even CT scans in the initial staging of lung cancer (see prior post on introduction to PET scans). PET scans are now nearly universally employed in the initial workup, at least of patients who have NSCLC and aren’t already known to have stage IV disease.

PET Scans for BAC

Article

PET scans are an important way to discriminate between metabolically active nodules, suggestive of cancer but sometimes representing inflammation or infection, and non-PET-avid lesions that are felt much likely to represent cancer. They are also a cornerstone of "clinical" staging by imaging and patient exam (vs. "pathologic" staging by surgery to clarify where cancer is or isn’t).

PET Scans For Restaging After Induction Treatment for Stage IIIA NSCLC

Purists have considered mediastinoscopy, which is invasive staging of the mediastinum through a small incision just at the base of the neck to get down behind the sternum, or breastbone, to be the "gold standard" for determining whether lymph nodes in the mediastinum, or middle of the chest, is involved with a cancer. The procedure is as shown:
