Lung Cancer / Mesothelioma
In a recent issue of the New England Journal of Medicine, a research group from Massachusetts General Hospital in Boston published some very promising results from their work showing that they can now detect circulating tumor cells (CTCs) from most patients with lung cancer and even detect EGFR mutations and other molecular findings from […]
0 CommentsIn the past couple of posts we’ve seen that based on evidence from Japan and Rome, number of lymph nodes resected and also the absolute number of positive nodes and/or proportion of positive nodes may be important prognostic variable. A third abstract I reviewed on the same subject came from Peoria, IL, and illustrated […]
2 CommentsAt this year’s ASCO meeting, I had the opportunity to review and provide commentary on several presentations from other researchers, all on the topic of how to refine our ability to predict how patients will do after surgery for stage I - IIIA NSCLC, with an idea that this information can help guide decisions […]
2 CommentsI’ve described mediastinoscopy as a “gold standard” preoperative procedure in patients who are candidates for surgery. Although it’s controversial whether patients with a very low likelihood or a very high likelihood of cancer in the mediastinal nodes (mid-chest, between the lungs) need to have this confirmed by obtaining tissue to review under a microscope, we […]
0 CommentsI was reminded of the important topic of occult N2 NSCLC by a comprehensive review that just came out in the Journal of Thoracic Oncology (abstract here) by a friend, thoracic surgeon Frank Detterbeck, who leads the thoracic oncology program at Yale. To review the basics of lymph nodes for lung cancer, N0 means no lymph […]
0 CommentsThere’s a website called Adjuvant! Online, developed by oncologist Peter Ravdin, that is best known for its use after surgery for breast cancer in assessing the value of post-operative chemo. Because I don’t really treat breast cancer, I haven’t spent time on the website, but I do know that it’s a valued resource among practicing oncologists who […]
0 CommentsAn interesting article just came out in the Journal of Clinical Oncology from researchers at Duke, led by Dr. Ed Patz of the Radiology Department there (abstract here). Recognizing the problems with detection of lung cancer (LC) based on symptoms (which detects LC far too late) or screening CTs (which detects early LC but also many […]
0 CommentsAlthough I’ve described this concept in a few posts over the past year, it’s time for me to dedicate some real discussion to the concept of individualizing treatment with the ERCC1 marker. ERCC1 stands for excision repair cross-complementing group 1, and it helps repair damage to DNA. Now, validated, reliable testing for ERCC1 in […]
6 CommentsA cancer has to grow faster than the tissue around it to become a tumor. Progressive growth is therefore a central feature of a cancer and a critical factor in distinguishing cancerous nodules from benign ones. There is a characteristic “volume doubling time” (VDT), the interval it takes for a nodule to double in volume. […]
11 CommentsAs you might suspect, there are features of different spolitary pulmonary nodules (SPNs) that makes us more or less suspicious for cancer. The first is the size of the nodule. Looking at multiple series of SPNs, the likelihood of cancer among nodules that measured under 5 mm is generally in the 0-1% range. Nodules […]
