Finding
Lung Cancer
Early detection is a cause worth fighting
for to save lives.
Aa the Leading Cause of cancer death for both men and women,
lung cancer kills more people than breast, prostate, colon and
pancreatic cancers combined. Fifty percent of those diagnosed with
the disease this year will have quit smoking decades ago, as was
the case for the late Peter Jennings. Newly diagnosed Dana Reeve,
widow of Christopher Reeve, never smoked at all. In fact, smokers,
current and former, should note that early detection is about you.
Carcinogenesis can occur after very little smoking, and detecting
cancer as early as possible can save lives.
Lung cancer is a disease
with staggering rates of mortality. Yet when diagnosed early, the
survival rates for stage 1 lung cancer can top 70 percent. But
early
detection has been difficult because lung cancer usually is asymptomatic until
it reaches an advanced stage.
There is no “gold standard” for early
lung cancer detection. And screening is a controversial issue because no data
currently exist to support
any method as the best screening tool. But clinical trials currently under
way are making great progress, breaking into new territory without
a lot of clinical
practice support.
The Lung Cancer Alliance believes late-stage diagnosis is
a lethal diagnosis, and finding new ways to diagnose lung cancer
earlier is an urgent need. We
strongly advocate for increased research dollars to expedite the review of
screening technology
and immediate research into safe and cost-effective treatment. Screening methods
for lung cancer currently include chest X-ray, sputum (saliva) cytology, computed
tomography (CT) and computerized molecular analysis of airway cell markers.
Early detection of cancer allows more choices for treatment and
management of the disease. The Lung Cancer Alliance prioritizes
the urgent need for methods
of early detection of lung cancer and population-based screening. The key to
making the screening decision is for patients to be well informed about state-of-the-art
screening with regard to a risk-benefit ratio. Patients can become informed
by
speaking with their doctor about the risks and benefits of various types of
screening.
At the Lung Cancer Alliance we are
following the progress of several major studies, including the International
Early Lung Cancer Action Program (I-ELCAP, www.ielcap.org)
and the National Lung Screening Trial sponsored by the National
Cancer Institute.
At
the 12th International Conference on Screening for Lung Cancer
in April, participants discussed data on more than 48,000 baseline
and follow-up CT scans
that had been
performed under the I-ELCAP study. I-ELCAP is a single-arm trial that is finding
best practices for early detection with new practices incorporated as the study
progresses. Data presented at the conference showed that more than 80 percent
of diagnoses were detected in stage 1 using spiral CT. In today’s environment,
only about 15 percent of lung cancer cases are diagnosed early. I-ELCAP researchers
estimate that more than 80 percent of lung cancer deaths could be prevented
by early intervention under CT screening, although this has not yet been proven.
The National Lung Screening
Trial (www.cancer.gov/nlst)
has enrolled 50,000 patients and seeks to determine whether spiral
CT scan or standard chest X-ray screening saves lives from lung
cancer. The data are expected to be available in 2009.
The Lung Cancer Alliance is a national nonprofit organization
that advocates for lung cancer patients, survivors, families and
caregivers. For more information,
