IT
IS TIME TO CONSIDER INSTITUTING 'STATIN' THERAPY FOR ALL LYMPHOMA
PATIENTS WITH 'NORMAL' LEVELS OF CHOLESTEROL AS WELL AS THOSE WITH AN
ELEVATED CHOLESTEROL

WITH SPECIAL
CONSIDERATION FOR PATIENTS TREATED WITH RADIATION THERAPY TO CHEST AND
NECK AREAS

IN PATIENTS TREATED FOR
HODGKIN'S DISEASE WITH RADIATION THERAPY TO THE CHEST AND NECK
AREAS THERE IS AN INCREASED INCIDENCE OF ATHEROSCLEROSIS IN CORONARY ARTERIES
AND OTHER MAJOR BLOOD VESSELS AS WELL AS DAMAGE TO THE HEART VALVES.
THIS HAS BECOME AN ESPECIALLY IMPORTANT DEVASTATING LATE

Excerpts from an Editorial in JAMA
High-Intensity Statin Treatment for Coronary Heart Disease
Journal of the American Medical
Association
(JAMA.March 3, 2004;291:1132-1134) Frank M. Sacks, MD, of the Harvard School of
Public Health
( NOTE that
all the emphasis markings are mine)
"All told, nearly 70 000 patients have participated
in large placebo-controlled clinical trials of statins of at
least 3 years in duration.
The study populations have been diverse, including those
without clinical evidence of coronary artery disease and
those with various presentations of coronary artery disease
prior to statin treatment.
Risk reduction has been similar (range, 20%-30%) across most
of these trials in mortality and in virtually every
atherosclerotic cardiovascular event that has been evaluated.
All of the statins that have been studied in these trials,
namely pravastatin (40-mg dose), simvastatin (20- to 40-mg
dose),
lovastatin (40-mg dose),
fluvastatin (80-mg dose), and
atorvastatin (10-mg dose),*** have produced risk reduction in
serious coronary vascular end points.
Although there is some variation between the trials in the
results of the population subgroups, considering the results
across all trials, it now seems true that statins produce
similar relative risk reduction across a wide variety of
patient types and clinical presentations. Therefore,
health benefit (i.e., absolute risk reduction), is principally
dependent on the underlying level of risk. This is explicitly
recognized by national guidelines for lipid treatment."
Excerpts from an Editorial in NEJM
INTENSIVE STATIN
THERAPY - A SEA CHANGE IN CARDIOVASCULAR PREVENTION
New England Journal of Medicine (Volume 350:1562-1564: April 8, 2004)
Dr. Eric J. Topol of the Cleveland Clinic Lerner College of Medicine and
the Department of Cardiovascular Medicine, Cleveland Clinic Foundation
(NOTE
that all the emphasis markings are mine):
"In the
management of atherosclerotic vascular disease, statin
drugs have already surpassed all other classes of medicines
in reducing the incidence of the major adverse outcomes of death,
heart attack, and stroke. A decade ago, their
effectiveness was first demonstrated by the results of the
Scandinavian Simvastatin Survival Study (4S), a trial that
provided definitive evidence of the benefit of simvastatin,
as compared with placebo, in improving survival.
By
1996, statins were dubbed "miracle drugs," and their
underuse was duly noted. Prominent scientists in
the field even speculated that heart attacks might be "gone
with the century."
Dr. Topol continued: "In 2002, the Heart Protection Study
not only confirmed the benefit of statins but raised new
questions. This study, the largest trial of a statin, showed
that an overall 25 percent reduction in the incidence of
coronary events was associated with a reduction of 40 mg per
deciliter (1.03 mmol per liter) in the LDL cholesterol level.
Equally important, patients with a "normal" base-line LDL
cholesterol level — that is, below 100 mg per deciliter
(2.59 mmol per liter) — according to the currently accepted
National Cholesterol Education Program guidelines for therapy, received
just as much benefit as those with high LDL cholesterol
levels."
"Taken
together, the REVERSAL and PROVE-IT trials herald a shake-up in
the field. Previously, it was considered optimal to lower the
LDL cholesterol level to less than 100 mg per deciliter. That
axiom has now come under serious question, because we know that
atherosclerotic progression and clinical outcomes will be
ameliorated by much more aggressive use of statins.
Indeed, the 80-mg dose of atorvastatin is the most intensive
LDL-lowering regimen for which data on clinical outcomes are
available."
It is clear that
we
are at a very important turning point but only if the number of persons
receiving statin therapy is increased as Dr. Topol noted
"Even today, only a fraction of the patients who
should be treated with a statin are actually receiving such
therapy."
But, now with the new
recognition of the value of the statins the number of patients treated
with statins should increase
and as Dr. Topol concluded:
"There
will soon be a sea change in the prevention and management of
atherosclerotic vascular disease. The proportional reduction in
major clinical outcomes that results from aggressive statin
therapy is of the same order of magnitude as that seen when
statins were compared with placebo in controlled trials. Intensive
therapy with statins, monitored by means of measurements of
LDL cholesterol or biologic markers of inflammation, is likely
to result in even greater steps toward actualizing the full
benefit of this remarkable class of medicines.

THIS RESEARCH RESULTED
IN A MAJOR MODIFICATION AND PUBLICATION OF
NEW STATIN DOSE GUIDELINES
(2004) TO ACHIEVE GREATER REDUCTION IN CHOLESTEROL
LEVELS
The value of more intensive statin therapy has just been approved
by a new set of national recommendations by an Expert Panel on
Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults
and a CLINICAL ADVISORY on how to use the STATINS was issued jointly by
the American College of Cardiology (ACC) the American Heart Association
(AHA) and the National Heart, Lung, Blood Institute (NHLBI) of the
National Institutes of Health and published in the medical journal of
the American Heart Association
Circulation. 2004;110:227-239.
It
is recommended that the administered dose of the statins should be high
enough to achieve the following results::
-
High-risk people: The
general goal of cholesterol-lowering treatment remains the same.
However, in order to
reduce LDL cholesterol levels to under 100 mg/dL, the panel makes an LDL
goal of less than 70 mg/dL a therapeutic option for people at very high
risk of heart attack or death.
Patients are considered at very high risk if they already have
cardiovascular disease plus diabetes, persistent cigarette smoking,
poorly controlled hypertension, or multiple risk factors of the
metabolic syndrome (high triglycerides, low levels of “good” HDL
cholesterol, obesity), and immediately after a heart attack.
-
Moderately high
risk: Moderately high-risk people are those who have multiple risk
factors and are estimated to have a 10 to 20 percent chance of heart
attack or cardiac death within 10 years.
The new guidelines reinforce the need
for treatment if LDL cholesterol levels are 130 mg/dL or higher, and
add an optional consideration of drug therapy if levels are between
100-129 mg/dL.
-
In general, if
drug therapy is used in people at high or moderately high risk, it
should be aimed towards achieving a 30 to 40 percent reduction in LDL
cholesterol.
-
Lower or Moderate
risk: Recommendations for treatment in people at lower or moderate
risk are unchanged.
-
Older people: Evidence
from the new studies bolstered the idea that it is never too late to
benefit from intervention to lower cholesterol levels.
As
of this date... there are no special statin recommendations for patients
treated with radiation therapy who are subject to the late occurring side
effect of artery and heart valve damage from the radiation... but it
is hoped that the Oncology groups in conjunction with the cardiologists
will pay attention to this issue and eventually make official special
recommendations for this unique group of individuals.
Each person
should review the need to receive a statin medication
with their physician... with the understanding that the importance of
adding statin medication after treatment with radiation therapy or after certain
particular types of chemotherapy probably will not be scientifically
determined with absolute certainty for at least 10-15 or more years in the
future… and will only be determined only after long-term monitoring and
follow-up study.

STATINS FOR A UNIQUE GROUP OF PATIENTS
AND
THE GENERAL POPULATION
Unfortunately, although statin therapy... as early as 1994... had
been shown to be of great value in reducing mortality from cardiovascular disease
(see references below)... no particular studies using 'statins'
have been conducted in patients who received or are about to receive
radiation therapy or other forms of cardiovascular toxins.
However, prudent advice would be to recommend
the institution of 'statin' therapy in these patients as they (especially
those who received upper body radiation therapy) are uniquely vulnerable to disability and early
death from cardiovascular (heart and blood vessel) disease. Although
this unique group of lymphoma patients constitutes an extremely small
portion of the general population they should be carefully monitored for
cardiovascular changes induced by their cancer therapy and they should
be added to the groups generally considered to be at higher risk for
cardiovascular disease who should receive statin treatment.
THE IMPORTANCE OF
STATIN TREATMENT in the GENERAL POPULATION
is EMPHASIZED BY THE DECISION BY THE BRITISH... as
reported by Lizette Alvarez in The New York Times on May 15, 2004: "Britain will become the
first country in the world to sell a cholesterol reducing drug, called a statin,
without a prescription"
"Starting in July, a low dosage
of the drug Zocor will be sold over the counter to people at moderate
risk of heart disease, a number that could reach 5 million to 10
million. That group includes all men older than 55, as well as men
over 45 and women over 55 who smoke, are overweight, have a family
history of heart disease or come from the Indian subcontinent, all
groups that are at higher risk than 'the general population'.
...The
decision to broaden the availability of statins is expected to curb the
rate of coronary disease in Britain, which kills 100,000 people in England
alone
...Dr. John LaRosa, a
nationally recognized expert on statins, said
Britain's decision was a significant step in the prevention of heart
disease despite the concerns, which he called reasonable. Preventive
efforts by doctors and governments to help stymie heart disease have not
been nearly as successful as they could be, he said.
"There is a significant
percentage of people who should be getting treated with statins who
are not getting treated for one reason or another," said Dr. LaRosa,
president of the State University of New York Downstate Medical
Center. "You can make an argument that something is better than
nothing."
The drugs, with few exceptions, have been proven safe and beneficial
to the "overwhelming majority of the patients who take them," he said.
On balance, he added, “They are much safer than aspirin.’’
LIZETTE ALVAREZ in The New York Times May 15, 2004
The success of achieving long survival times
in patients treated for Hodgkin's disease and other lymphomas has to be
tempered with the fact that many young patients will not achieve a true
old age status because of the development of various late developing
complications secondary to their radiation treatment and/or chemotherapy
treatment that is destined to cut their life short unless various
successful interventions can be achieved.
Therefore, the
institution of 'statin' therapy may prove to be a means to prevent one serious
late occurring
side-effect of radiation treatment that reduces life expectancy. Certainly
if statin therapy is good for the general population it should not cause
any harm in the lymphoma population. On a strict scientific basis
this remains to be exactly determined.
To settle this
issue Oncologists, in general, and Radiation Oncologists in particular
should institute clinical studies in conjunction with cardiology
specialists even if this proves to be a relatively complex study... because
the statin dose needed to get the best
results... and the exact time to start the statin therapy once radiation
treatment is completed... must also be determined.
At this time, however, the ability to
obtain even a low statin dose 'over
the counter' at a reasonable price may prove to be a good start to a
potentially wonderful outcome.

“CONCLUSIONS:
The results of the current study provided some degree of assurance to the
increasing numbers of women using statins that such use is not
associated with an increased risk of breast cancer.
Although the data gave some support to a reduced risk of
breast carcinoma among long-term users of statins, further research is
needed to confirm this association.”

HMG CoA reductase inhibitors and the risk of
colorectal cancer.

BACKROUND:
3-hydroxy-2-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors (statins)
are effective lipid-lowering agents that also inhibit the growth of
colon cancer cell lines and were noted to be associated with a reduced
risk of colorectal cancer (CRC) in a randomized clinical trial of
patients with myocardial infarction.
METHOD:
The association between HMG CoA reductase inhibitors and colorectal
cancer in a population-based case-control study of incident CRC was
investigated. The Molecular Epidemiology of Colorectal Cancer Study (MECC)
is a study of 1608 colorectal cancer cases diagnosed in northern Israel
between 1998 and 2002, and 1734 population-based controls matched for
age, gender, and ethnicity
CONCLUSION:
HMG CoA reductase inhibitors (statins) are associated with a 51%
reduction in the risk of colorectal cancer, and the protective effect is
specific to this class of lipid-lowering agents. The significant
protective effect of HMG CoA reductase inhibitors in CRC indicates that
these drugs deserve further investigation in chemoprevention and
therapeutic clinical trials.

Our data suggest that statins are protective when used longer
than 4 years (adjusted OR, 0.64; 95% CI, 0.44 to 0.93) or when
more than 1,350 defined daily doses are taken (adjusted OR,
0.60; 95% CI, 0.40 to 0.91). “
“CONCLUSION: This observational study suggests that statins may
