Women who used aspirin on a regular basis had a reduced risk of death from cardiovascular disease and cancer according to data from the Nurse’s Health Study.  Deaths from colorectal cancer were reduced by 28 percent.

The Nurse’s Health Study has followed nearly 80,000 women over 24 years.  During that time nearly 10,000 women have died.  Overall deaths were 25 percent lower among women who reported regular aspirin use.  Aspirin had a larger impact on cardiovascular deaths, reducing them by 38 percent, than on cancer which had a 12 percent reduction. 

In addition, cardiovascular mortality reduction was seen sooner, after five years of aspirin use compared to ten years for cancer.

Writing in the March 26, 2007 Archives of Internal Medicine, Andrew T. Chan, MD, MPH and his colleagues concluded,

In women, low to moderate doses of aspirin are associated with significantly lower risk of all-cause mortality, particularly in older women and those with cardiac risk factors. A significant benefit is evident within 5 years for cardiovascular disease, whereas a modest benefit for cancer is not apparent until after 10 years of use.

However, it is important to realize that regular aspirin use has risks as well as benefits.  The US Preventive Services Task Force recommends against the routine use of aspirin and other non-steroidal anti-inflammatory drugs to prevent colorectal cancer.

An additional article about the study appears on the Cancer Consultants website.

Elizabeth Lamphere taught me to think.  She taught me to consider evidence, to work through problems — scientific and otherwise.  She’s a big reason why I write about medical science today.

She died on March 27, 2007 at the age of 90.

She was an extraordinary teacher, organizing extracurricular science projects for her students — including me.  Many nights she was in the high school lab until nearly ten o’clock giving us a chance to learn science hands-on.  She was tough, never allowing us to cut corners, demanding excellence.

I left high school fully expecting that I would be a scientist of some sort.  My life turned out quite differently, but her training in problem-solving, hard work, and curiosity stayed with me my whole life.

I mourn her passing and celebrate her inspiring life.

I know that she would be pleased that the American Association for Cancer Research is hosting 300 Los Angeles area high school students at their annual meeting.  After presentations about cancer research, each student will be matched with scientist mentor to visit scientific displays of research results.

C3: Colorectal Cancer Coalition is pleased to help announce the introduction of the Colorectal Cancer Prevention, Early Detection and Treatment Act of 2007 (HR 1738).

The legislation, sponsored by United States Representatives Kaye Granger (R-TX) and Albert Wynn (D-MD), was formally announced at an event on March 28, 2007 marking National Colorectal Cancer Awareness Month. C3 joined the event along with the American Cancer Society Cancer Action Network (ACS CAN), Cancer Research and Prevention Foundation (CRPF) and Hadassah to show our combined support for the bill.

“With 52,000 Americans expected to die from colorectal cancer in 2007 alone; it is vital that we begin to properly invest in research, prevention and treatment in order to save lives,” said Carlea Bauman, Executive Director of C3: The Colorectal Cancer Coalition. “Colorectal cancer patients have been neglected for too long, but through legislation like this, we will see progress against this terrible disease.”

This bi-partisan legislation would establish a program administered by the Centers for Disease Control and Prevention (CDC) and would authorize $50 million in funding for grants to the states. The grants would be used to conduct programs to provide vital colon cancer screenings, information and follow-up services to those ages 50-64, with a focus on those most at risk, such as low-income, uninsured and underinsured men and women.

While Erbitux® (cetuximab) can shrink tumors and increase the time before cancer gets worse for some patients whose colon cancer has spread, not all people respond to it.  French scientists have found that patients with a KRAS mutation in their tumor were very unlikely to show any tumor shrinkage when they are treated with Erbitux.  In addition, the time before their disease progressed was significantly shorter.

KRAS is a gene that signals proteins to encourage cell growth.  Mutations in KRAS are associated with some, but not all, colorectal cancers.

Studying 59 patients who were treated with cetuximab and chemotherapy, the researchers found that 22 had a KRAS mutation in their tumor.  None of these KRAS-positive patients responded to treatment.  On the other hand, all 12 patients who did respond did not have KRAS identified.

Time to disease progression for those with KRAS was 3 months compared to 5.5 months for patients without the mutation.

Patients studied were being treated with cetuximab and chemotherapy after progressing on standard chemotherapy.

Dr. Frederic Di Fiore led the group of researchers in Rouen in analyzing the tumors and patient outcomes.

Health Talk is presenting a live Webcast to help cancer patients and their families understand the importance of second opinions, how to access them, and how to decide among differing opinions. 

Cancer Patient’s Guide to Second Opinions

• Tuesday,April 3, 2007
• 7 p.m. (Eastern)
• Access via the Internet
• Register

Registration is helpful, but not required.  If you haven’t registered you can go to the Webcast site about 10 minutes prior to 7 p.m.

The Health Talk staff says,

Even though second opinions can save lives, guilty feelings and a sense of loyalty often keep cancer patients from making the appointment.
