About a week ago, as most of you are now aware, the annual American Society of Clinical Oncology (ASCO) meeting was held in Orlando, Florida. Tens of thousands of oncologists, nurses, radiation oncologists, pulmonologists, surgeons, radiologists, pathologists, financial advisors, and pharmaceutical representatives descended on Mickey Mouse-land for schmoozing and sunshine… I mean, for the presentation of the most up to date research in the cancer world.

Maintenance therapy for advanced non-small cell lung cancer was certainly the big theme this year in the lung cancer presentations. Let's start with the Alimta data. Dr. West has outlined earlier results of this study after this data was presented at the 2008 ASCO meeting.

The ASCO meeting I'm at right now is so busy that there really isn't time to write a new post (though I'm still "tweeting from the meeting"). Though the talk show hows just air re-runs of old shows when they're on vacation, I'm trying to continue to add new content to the website during this time (and it's about as far from a vacation as anyone has in Orlando).

The ASCO meeting I'm at right now is so insanely busy during the days and nights that it's next to impossible to carve out the time to write posts during the meeting. While the talk show hosts just show re-runs while they're on vacation, we're at least going to put up some new content, even if it's from work previously done (and this is far from a vacation).

With special thanks to Harvey and Bernice Janssen for providing support to make it possible, I'm pleased to post a new video presentation on the topic of Timing the Transition to Maintenance/Second Line Chemotherapy for Advanced NSCLC. We can expect new information to emerge in the coming months and years, but here is the current snapshot of what we know, along with a little describing what I think (noted as such), about this important topic today.

Several weeks ago, I described the results of a survey I sent out to several colleagues who are lung cancer experts around the country, asking how they would manage a case of a newly diagnosed Caucasian never-smoking patient with advanced NSCLC, adenocarcinoma, and asymptomatic subcentimeter brain metastases, treated with whole brain RT before starting systemic therapy.

There's been several discussions about the potential value of maintenance therapy after the initial chemotherapy for SCLC; I've discussed this subject in a prior post, in which I focused on chemo -- while the results haven't been strong enough to lead to a change in standard practice, at least one trial showed a strong trend in the right direction.

I had previously mentioned in prior posts that there have been a few studies in advanced NSCLC that indicate that about 4 cycles provides as much treatment benefit as continuing first-line chemo until progression. I also noted that the ECOG 4599 trial (abstract here) gave up to 6 cycles of chemo (with carbo/taxol) and avastin, followed by avastin alone as a maintenance therapy until progression of the cancer.

As I described in a post describing the general principles of SCLC, it is typically responsive to treatment initially, but upon recurrence it is much less likely to respond.

The oral EGFR inhibitors Iressa and Tarceva both have activity in advanced NSCLC, with proven responses in a minority of patients and improvements in cancer-related symptoms as well.
