miRNA as a potential biomarker for early breast cancer

One way to potentially improve long term cancer statistics is earlier detection, and in high risk patients, appropriate initiation of earlier treatment, since it is well known that the survival in stage II or III breast cancer is noticeably better than that for stage IV metastatic disease.

A critical question then, is how do we improve earlier detection?

There are a number of ways to achieve this:

  1. Imaging techniques
  2. Prognostication
  3. Diagnostics
  4. Biomarkers

Gene mutation and resistance to chemotherapy in colorectal cancer

This week’s New England Journal of Medicine (NEJM) contained a fascinating article on how a specific gene mutation known as Transcription factor AP-2 epsilon, TFAP2E–DKK4, appears to be responsible for inducing at least some of the resistance to chemotherapy that occurs during treatment of colon cancer.

At first sight, I wasn’t sure from the abstract if they were referring to either adaptive resistance to therapy or whether genetic changes already present limited the effectivenes of the treatment.

Further reading of the full article more specifically pointed to the latter:

AVEO announces front-line data in renal cell cancer for tivozanib

A very happy New Year everyone!  After shaking off the dust of an extended break over the last two weeks, this morning brought plenty of news to kick start 2012.

logo AVEO announces front line data in renal cell cancer for tivozanibThe most interesting news was AVEO-Astellas’ announcement regarding their VEGF inhibitor, tivozanib, in advanced renal cell cancer (RCC):

“Tivozanib demonstrated superiority over sorafenib in the primary endpoint of progression-free survival (PFS) in TIVO-1, a global, randomized Phase 3 clinical trial evaluating the efficacy and safety of investigational drug tivozanib compared to sorafenib in 517 patients with advanced renal cell carcinoma (RCC).”

What’s hot at SABCS – Update 2 – advanced breast cancer

After a number of basic research and science sessions over the last two days (see the Update 1 post on the science that intrigued me for more details), but the last two days heralded some excellent clinical sessions, in both oral and poster forms. These included the presentation of the much anticipated update to the BOLERO-2 trial, which was also published in the New England Journal of Medicine online and the CLEOPATRA study, also published in the same journal.  One of the more impressive posters that caught my eye was the ENCORE 301 study, which provided an update to the entinostat data in ER/PR+ HER2- advanced breast cancer.

What's hot at SABCS – Update 1

Yesterday evening brought a flurry of news around the New England Journal of Medicine articles for the BOLERO2 and CLEOPATRA trials, but out of respect to the presenters, I hate talking about the actual data before its being presented. Call me old fashioned if you like, but it seems odd moving up deadlines for the publication ahead of the presentations instead of releasing them on the day and is a little disrespectful of the journal towards the presenter and attendees.

Video preview of San Antonio Breast Cancer Symposium 2011

What’s hot at the 2011 San Antonio Breast Cancer Symposium?

There is a lot of exciting data coming out at SABCS 2011 over the next three days, including the BOLERO2, CLEOPATRA and NEOSPHERE clinical trial data.

I previously wrote about the exciting BOLERO2 results that were presented at the European Multidisciplinary Cancer Conference (ECCO/ESMO 2011) in Stockholm in September. More data is expected at SABCS to coincide with a publication in the New England Journal of Medicine (NEJM).

The following video outlines some of the data that I think is hot at SABCS and why it’s worth watching out for. I will be writing more about it as it’s presented.

EGFR activates mTORC2 in glioblastoma – a potential role for new therapies

One of the great things about following the American Association for Cancer Research (AACR) on Twitter, is that they regularly share technical open access articles from their journals for scientists to read.  Of course, many will have access through their institution subscription, but there are also probably quite a few interested community oncologists and scientists like me that don’t. The idea of sharing some of their really important scientific research with the broader public is a great one – a little bit of goodwill goes a long way and furthers their cause too.

Gone to dog drug heaven…

That was the quaint phrase used by one of the presenters at the recent AACR-EORTC-NCI Molecular Targets meeting in San Francisco.

Apparently, some drug or two was considered, too toxic (fair enough) or lacking in efficacy, hence the requisite binning of a multi-million dollar program to the scrapheap.

Yesterday’s post, however, reminded me that maybe sometimes, it’s not that the efficacy was lacking but the clinical trial design or tumor type or even line of therapy was the best one.  Let’s consider a couple of recent ideas here:

Exciting new approach to targeted therapy in prostate cancer

Last week a very interesting article appeared in Cancer Discovery that reported a new target in neuroendocrine tumours (NET) of the prostate, a particularly aggressive subtype. Now, these tumours are “rare” and “uncommon” based on a spot check with a couple of oncology specialists I asked this morning.  In fact, according to this latest research, fewer than 2% of men with prostate cancer actually present with neuroendocrine disease and adenocarcinoma of prostate can also (rarely) evolve into neuroendocrine disease, but overall, the prognosis for NET of the prostate is generally poor.

Update from AACR Molecular Targets 2011 #1 – Breast Cancer

Last week I had an enjoyable time at the AACR-EORTC-NCI Molecular Targets meeting but gippy wifi in San Francisco followed by my blog hosting and RSS feed going haywire meant that reviews of the meeting were delayed until now. There are a couple of interesting topics that emerged during the meeting that I’m going to explore in extended posts this week.

Today’s review looks at new breast cancer data from the conference. There were two things that stood out for me:

  • The role of epigenetics in advanced ER/PR+ breast cancer
  • New potential targets for inflammatory breast cancer (IBC)
