Among the many novel concepts in managing immunotherapy is the potential for “pseudo-progression”. This unusual phenomenon is when a patient’s scans of the areas of cancer actually appear worse on early imaging, potentially even with new lesions, after starting immunotherapy, but a patient’s scans later show shrinkage of the cancer.  These patients typically feel well, often with improvement in their cancer-related symptoms (fatigue, appetite, etc.) that don’t seem to be concordant with their worse-appearing scans.

With positive trials of two immune checkpoint inhibitors, Opdivo (nivolumab) and Keytruda (pembrolizumab), in second line NSCLC and compared with Taxotere (docetaxel), it should come as a surprise to nobody that another checkpoint inhibitor, Tecentriq (atezolizumab) has also proven superior to Taxotere in the OAK trial of previously treated NSCLC patients, as reported in a press release today.

Dr. Eddie Garon considers the data on immunotherapies for first line treatment of advanced NSCLC and whether we are likely to use these agents instead of or in combination with standard chemotherapy soon.

UCLA Med Center's Dr. Eddie Garon discusses the open question of the optimal duration of ongoing treatment with immunotherapy for lung cancer.

Drs. Ben Solomon, Leora Horn, & Jack West review impressive data demonstrating a striking survival improvement from successful efforts at smoking cessation among smokers undergoing lung cancer CT screening.

As we learn more about immunotherapy for lung cancer, combinations with multiple immunotherapy agents are being explored. Medical oncologist Dr. Eddie Garon considers whether combinations are likely to emerge as the leading immunotherapy approach.
