We’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.

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.

As a conclusion to the string of posts on the topic of lymph nodes removed at the time of surgery, I wanted to touch on the issue of what our representative experience is in the US, because I described the results of specialized centers in Japan and Italy that typically yielded large numbers of lymph nodes, often more than 10.

In 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 a key reason why using these variables may not be as consistently useful as we’d like, at least in many parts of the world.

In the last post I discussed some interesting work from a group in Japan that suggested that the number of lymph nodes that are removed and positive for NSCLC may be a very important prognostic variable, potentially an even more important factor than location of the nodes, which is the basis for how we stage nodal involvement in NSCLC now.

At 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 about who should receive chemo and who shouldn't.

A couple of weeks ago I described in a prior post the design and general results of a trial coded as JMEN by the sponsor company, Eli Lilly. This study randomized patients to either maintenance/early second line alimta (pemetrexed) or a placebo after four cycles of initial platinum-based doublet chemo with a drug other than alimta.

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

There's a single lung cancer trial being presented 6/1/08 at ASCO's Plenary Session, at which the most important cancer studies of the year are presented. This is on the FLEX trial that I described in a prior post, and which was already reported to be positive, at a press release all the way back in September of last year.
