The FLEX trial raises a number of additional points as we struggle to determine how to integrate Erbitux (cetuximab) into the current standards of care. One question is whether we can refine how well we do with Erbitux by using clinical or molecular variables to select better or worse candidates for it. I already mentioned in my prior post that Asian patients (among whom 52% were never-smokers) had a far better survi

Within the lung cancer community, the biggest story from the ASCO meeting was the long-awaited plenary session presentation (abstract here) of the FLEX trial of chemo with or without the EGFR monoclonal antibody Erbitux (cetuximab) that we knew was statistically significantly positive for an overall survival benefit as far back as September of last year (see

When I first started OncTalk, there was a lot of buzz about celebrex (celecoxib) as a cancer drug, but almost all of it was among patients talking about it on the internet: oncologists watching the field hadn't been impressed by the early returns, including this one (despite the fact that some of my earliest work in lung cancer was on cyclo-oxygenase-2, or COX-2, the target of celebrex).

As I've described in a prior post, there is some evidence that patients who develop a rash on tarceva (erlotinib) have an improved survival compared to patients who experience no skin toxicity on tarceva. The key question is whether this is an issue of under-dosing some patients, or if it's just a correlate of overall immune function or constitution in a person, in which case increasing the dose won't improve the outcome.

Last year, a provocative trial was presented at ASCO that compared early vs. later taxotere as second line therapy. I described that study here, and it showed a very significant improvement in progression-free survival (PFS) and a near significant improvement in overall survival (OS) for the recipients of taxotere immediately after four cycles of first line chemo for advanced NSCLC.

At 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) in the 1st or 2nd line setting. The groups were similar, remember this was not a randomized prospective study; the median age was 65 for those receiving Tarceva and 74 for those on Iressa. About 26% of the whole group were never/former smokers.

Last week, the preliminary results of interim analysis the ESCAPE (Evaluation of Sorafenib, Carboplatin, And Paclitaxel Efficacy in NSCLC) trial were presented by Dr. Scagliotti at the 1st IASLC (International Association for the Study of Lung Cancer)-ESMO (Eurpean Society for Medical Oncology) Lung Cancer Conference in Geneva, Switzerland. This was a randomized, placebo-controlled, double-blind phase III study for patients who have not yet had chemotherapy for advanced NSCLC.

Continuing with the analysis of a publication about tarceva (erlotinib) for patients with advanced BAC that I introduced in the last post, we'll turn now to the analysis that Dr. Vince Miller and colleagues did on the biomarkers that might predict more or less clinical benefit with an EGFR inhibitor like tarceva (abstract here).

In a recent issue of the Journal of Clinical Oncology, Dr. Vince Miller and colleagues published the results of an important trial of the EGFR inhibitor tarceva (erlotinib) in the unusual NSCLC subtype bronchioloalveolar carcinoma, or BAC (abstract here). This work was predicated on the observation, also by Dr.

Tumor cavitation has been one of the issues we really haven't discussed but that has been a challenging question as we test more and more anti-angiogenic drugs, which target the tumor blood supply, in the setting of lung cancer. Since we started testing these agents, we've noticed that in addition to sometimes increasing the rate of tumor shrinkage, many patients who receive anti-angiogenic drugs develop cavitation, or a response on the inside of the tumor that leaves the rim of the tumor intact, as shown here:
