Lung Cancer / Mesothelioma
I just recently wrote a post (here) that describes how I became convinced that under certain circumstances there could be a genuine value in determining whether a particular lung cancer patient has a tumor with an EGFR activating mutation. While these have seemed to predict that these patients are quite likely to respond with […]
0 CommentsThough EGFR inhibitors like tarceva can produce some terrific and long-lasting results in many patients, they aren’t toxicity-free. The “targeted therapies” we use just have a very different side effect profile from standard chemo, and the EGFR inhibitors are well known to have skin-related side effects as the leading problem, with loose stools/diarrhea as […]
3 CommentsThere are two widely tested epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) — iressa (gefitinib) and tarceva (erlotinib). As discussed in my summary of their history (posts here and here), iressa was the first out of the gates, but it failed to demonstrate a significant survival benefit compared with […]
0 CommentsOne of the topics that frequently occurs in the clinic, and that patients often ask about, is the situation in which there is some suggestion of slight progression. This can take the form of many different situations: a rising tumor marker (see prior post), a slight increase in the uptake on PET (see prior […]
3 CommentsWe’ve been following sorafenib (nexavar), a multi-kinase inhibitor with anti-angiogenic activity (see prior post). This oral agent, which is already approved as an effective treatment for cancers of the liver and kidney. It’s been studied as a single agent and appears to perhaps be associated with prolonged stable disease even if not with clear tumor […]
8 CommentsOne of my earliest posts when I started OncTalk was on the use of oral inhibitors of the epidermal growth factor receptor (EGFR), one of the growth signals that is often over-active in cancer cells, against advanced bronchioloalveolar carcinoma (BAC), a unique subtype of lung cancer that tends to grow within the […]
1 CommentsAt the 1st ESMO-IASLC Lung Cancer Conference in Geneva last week I saw a presentation that I thought would interest this general readership. The study, presented by Dr Grossi, from Italy, is a retrospective review of 61 patients with advanced NSCLC of all subtypes treated with either Tarceva (erlotinib) or Iressa (gefitinib) […]
3 CommentsOne of the novel agents being studied in lung cancer is sutent (sunitinib), a multi-targeted oral anti-angiogenic drug that I’ve described in a prior post. While I’ve mentioned a small study I’m leading at my own institution with this agent in advanced NSCLC patients with bronchioloalvelar carcinoma (BAC) or who have never smoked (information […]
1 CommentsThe issue of population-based differences in response to lung cancer treatments was essentially introduced with the EGFR inhibitors, so it’s appropriate to introduce racial differences overall with this work. Mention of more favorable results with EGFR inhibitors iressa and tarceva emerged with the earliest clinical studies and have since become a well established truism. […]
2 CommentsMember Sandra recently asked the question that several other people have asked in one form or another: how do we choose among the treatment options for second line therapy in NSCLC. I’ve covered in several posts and a huge number of responses in the Q&A Forum the leading options we generally consider for second line […]
