One 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 lungs, sometimes slowly, and not progress elsewhere.

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).

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.

So I’ve been invited to be on the faculty of a lung cancer conference in Kauai next month (yes, a good gig, but this is the first year that the flights are so expensive that I can’t bring my family to this normally very family-friendly event), and my topic is to argue in a debate about whether molecular testing for EGFR should be routinely used in clinical practice.

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.

Although it’s only a leak from a “reliable source”, news came yesterday (link here) about a new lung cancer development from a financial source (yet another example of us learning oncology from Wall Streeters). Specifically, we heard that the BMS-099 that I described in a prior post is actually demonstrating a significant benefit in overall survival (OS).
