One of the key points that has been established in first line treatment of advanced NSCLC is that two drug chemotherapy is superior to one drug chemo. Several trials from a decade ago showed that a two drug "platinum doublet" led to a longer overall survival than either a platinum alone (typically cisplatin at the time that these trials were performed) or another agent, such as paclitaxel alone.

A few weeks ago I described a blood test for predicting survival after getting an oral epidermal growth factor receptor (EGFR) inhibitor that is just becoming commercially available. This is called the Veristrat test and from company called Biodesix.

One of the general rules in oncologist is that we typically use our most effective treatments first, and often early, though there are certainly exceptions. Women with metastatic breast cancer may have a higher response rate by receiving combination chemotherapy than single agent chemo, but when a gentle single drug chemotherapy or hormone therapy option will do very well and provide fewer side effects, that’s usually the approach we recommend until bigger guns are needed.

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.

One of the most pressing issues in lung cancer research is in identifying patients who could benefit from a particular drug, both to increase their chances of having a good outcome and to spare everyone else from an ineffective drug with unnecessary toxicity. There have been some exciting advances in this field, but before I elaborate I want to give some (simplified) background on how drugs are traditionally developed. Classically, potential cancer drugs are tested on cancer cell lines in a Petri dish, and if the drug appears to kill the cells, it is then tested in animals.

About 18 months ago, I wrote a post about a new technique being developed that looks at the pattern of proteins in the blood of a patient in order to determine whether a patient is likely to do well or poorly after receiving an EGFR tyrosine kinase inhibitor like tarceva (erlotinib) or iressa (gefitinib) for advanced NSCLC.
