BRIEF RESUME OF THE INTENDED WORK
6.1
INTRODUCTION
Health is the level of functional or metabolic efficiency of a living being. In humans,
it is the general condition of a person's mind and body, usually meaning to be free from
illness, injury or pain (as in "good health" or "healthy"). In order to have a good health good
nutrition is essential1.
Good nutrition is essential to good health through out life, beginning with child life
and extending to old age. Food and nutrition continue to provide essential support during the
adult aging process. Good nutritional status through out life helps prevent the development
and progression of disease and disabilities in later life, as well as promoting successful
medical treatment outcome, thereby significantly contributing to the quality of life.
Throughout life good nutrition is required to stay away from diseases like cancer.
Cancer is a group of diseases with similar characteristics, which can occur in all
living cells in the body and different cancer types have different natural history. The myth
that cancer affects people mostly in the developed countries is being broken by the fact that,
of the 10 million new cancer cases seen each year worldwide, nearly 5.5 million are in the
less developed countries. Cancer is the second most common cause of death in the developed
world and a similar trend has emerged in the developing countries too. Cancer prevalence in
India is estimated to be around 2.5 million, with over 8,00,000 new cases and 5,50,000
deaths occurring each year due to this disease. More than 70% of the cases report for
diagnostic and treatment services in the advanced stages of the disease, which has lead to a
poor survival and high mortality rate2.
Antioxidants are substances that may protect cells from the damage caused by
unstable molecules known as free radicals. Free radical damage may lead to cancer.
Antioxidants interact with and stabilize free radicals and may prevent some of the damage
[3]
free radicals might otherwise cause. Examples of antioxidants include beta-carotene,
lycopene, vitamins C, E, and A, and other substances3.
Free radicals create a destructive process in our cells, causing the molecules within
the cells to become unstable. They may even be a big player in the formation of cancerous
cells by a “chain-reaction” effect, causing other cells to become damaged. Because of the
inherent instability of free-radicals, they try to attack other healthy cells to get stable
themselves. This causes the once-healthy cells to react in the same way, attacking others in
never-ending attempt for cellular stability.
Antioxidants help fight oxidation, a normal chemical process that takes place in the
body every day. It can be accelerated by stress, cigarette smoking, and alcohol. When there
are disruptions in the natural oxidation process, highly unstable and potentially damaging
molecules called free radicals are created. Oxygen triggers the formation of these destructive
little chemicals, and, if left uncontrolled, they can cause damage to cells in the body. It's
much like the chemical reaction that creates rust on a bicycle or turns the surface of a cut
apple brown.
Antioxidants neutralize free radicals as the natural by-product of normal cell
processes. Free radicals are molecules with incomplete electron shells which make them
more chemically reactive than those with complete electron shells. Exposure to various
environmental factors, including tobacco smoke and radiation, can also lead to free radical
formation. In humans, the most common form of free radicals is oxygen. When an oxygen
molecule (O2) becomes electrically charged or “radicalized” it tries to steal electrons from
other molecules, causing damage to the DNA and other molecules. Over time, such damage
may become irreversible and lead to disease including cancer. Antioxidants are often
described as “mopping up” free radicals, meaning they neutralize the electrical charge and
prevent the free radical from taking electrons from other molecules4.
[4]
Free radical production is actually a normal part of life, part of the equation of simply
breathing in oxygen. Usually, the body's natural defense systems neutralize free radicals that
develop, rendering them harmless. However, environmental assaults on the body, such as
UV-radiation, pollutants and alcohol, can overpower the body's ability to neutralize free
radicals, allowing them to cause damage to the structure and function of the body's cells.
There is good evidence that this damage contributes to aging and leads to a host of illnesses,
including cancer and heart disease5.
Considerable laboratory evidence from chemical, cell culture, and animal studies
indicates that antioxidants may slow or possibly prevent the development of cancer.A 2009
study looked at data from NHANES (1999–2000 and 2001–2002) and the U.S. Department
of Agriculture Flavonoid Database to estimate the total antioxidant intake (from diet and
supplements) of adults in the United States. The researchers calculated the daily intake of
vitamin C, vitamin E, carotenes, selenium, and flavonoids. They found that supplements
accounted for 54 percent of vitamin C; 64 percent of vitamin E (alpha-tocopherol); 14
percent of carotenes; 11 percent of selenium; and 2 percent of flavonoid intake. Nutritional
deficit have been shown to contribute significantly to many diseases that occur in the
elderly6.
[5]
6.2
NEED FOR THE STUDY
Cancer is a leading cause of death in the United States alone. Nearly 23% of all
deaths are cancer related. This statistic is frightening and the reason so much emphasis is
placed on can cancer treatments and preventions. The adage "An ounce of prevention is
worth a pound of cure" is particularly relevant when it comes to cancer, so it is very
important that the general population is aware of how to promote health naturally in order to
stave off cancer.
There are many different forms of cancer and various effects that can lead to it.
However, lack of antioxidants has been shown to exacerbate conditions that may lead to
cancer. According to the American Cancer Society, there is clear evidence that a lack of
antioxidants can increase risk of cancer and cancer related deaths. Research has proven
beyond a reasonable doubt the connection between antioxidants and cancer.
The human body has several innate defense systems against free radicals. However,
the innate oxidant defense system is not sufficient to adequately deal with the amount of free
radicals produced and is now thought that dietary antioxidants which counter free radicals,
are essential for health and well being .
The earliest and most important way to stop free radical damage is to fortify your diet
with antioxidant rich food. Consuming more antioxidant helps provide the body with tools to
neutralize harmful free radicals. It is estimated that there are more than 4000 compounds in
foods that act as antioxidants. The most include vitamin C, E, beta carotene and the mineral
selenium. Antioxidants-food substances that slow down cell damage and may improve
immune function and keep the body healthy.
The first large randomized trial on antioxidants and cancer risk was the Chinese
Cancer Prevention Study, published in 1993. This trial investigated the effect of a
combination of beta-carotene, vitamin E, and selenium on cancer in healthy Chinese men and
[6]
women at high risk for gastric cancer. The study showed a combination of beta-carotene,
vitamin E, and selenium significantly reduced incidence of both gastric cancer and cancer
overall7.
A randomized trial of selenium in people with skin cancer demonstrated significant
reductions in cancer and cancer mortality at various sites, including colon, lung, and prostate.
The effects were strongest among those with low selenium levels at baseline.
A study conducted on defining the role of antioxidants in the prevention of prostate
cancer. This is the largest individually randomized, multicenter cancer prevention trial
conducted that has maintained high rates of adherence and retention for 4 to 7 years. This
trial recruited 35,533 men who were randomly assigned to four groups (selenium, vitamin E,
selenium + vitamin E, and placebo) in a double-blind fashion between 2001 and 2004.
Eligibility included age 50 years or older (African American men) or 55 years or older (all
other men), a serum prostate-specific antigen level of ≤4 ng/ml, and a digital rectal
examination not suspicious for prostate cancer. Antioxidant formulations used were oral
selenium (200 μg/d from L-selenomethionine) and matched vitamin E placebo, vitamin E
(400 IU/d of all rac-α-tocopheryl acetate), and matched selenium placebo, selenium +
vitamin E, or placebo + placebo for a follow-up of minimum of 7 years and a maximum of
12 years. The primary outcome was prostate cancer and prespecified secondary outcomes
were lung, colorectal, and overall primary cancer. At median overall follow-up of 5.46 years
(range: 4.17–7.33 years), hazard ratios for prostate cancer were 1.13 (99% CI, 0.95–1.35; n =
473) for vitamin E, 1.04 (99% CI, 0.87–1.24; n = 432) for selenium, and 1.05 (99% CI, 0.88–
1.25; n = 437) for selenium + vitamin E vs. 1.00 (n = 416) for placebo. There were
statistically non significant increased risks of prostate cancer in the vitamin E group (p =
0.06) and Type 2 diabetes mellitus in the selenium group (relative risk, 1.07; 99% CI, 0.94–
1.22; p = 0.16).This study concluded that selenium or vitamin E alone or in combination at
the doses and formulations used prevent prostate cancer8.
[7]
The investigators personal experience is that while he was working in the medical I
C U, a majority of the client who were admitted suffered from some nutritional disorders and
cancer and in most cases the care givers were unaware of the special nutritional needs of the
cancer client. All these factors prompted the investigator to assess the knowledge of the staff
nurses and to plan teaching to improving the nutritional needs to prevent and treat cancer.
[8]
6.3
REVIEW OF LITERATURE
A study was conducted on Antioxidants and Cancer Therapy at Institute for Integrative
Cancer Research and Education, Evanston. The objective was the consideration of whether to use
antioxidants concomitantly with chemotherapy and radiation therapy. First, the early hypotheses
of the role of antioxidants in carcinogenesis gave a simplified and often inaccurate picture of the
physiological effects of specific antioxidants. Antioxidants can have protective effects that have
nothing to do with oxidation; on the other hand, they can under some circumstances develop
prooxidant properties and promote carcinogenesis. A number of clinical studies have already
demonstrated beneficial effects of antioxidants in ameliorating side effects of chemotherapy. The
study concludes that more theoretical work on the chemistry of antioxidants and chemotherapy
drugs suggests that antioxidants might improve therapeutic efficacy of antineoplastics by
counteracting aldehydes that impede the passage of cells through the cell cycle9.
A study was conducted on Daily intake of antioxidants in relation to survival among
adult patients diagnosed with malignant glioma. Adult patients diagnosed with malignant
glioma during 1991-1994 and 1997-2001 were enrolled in a population-based study.
Diagnosis was confirmed by review of pathology specimens. The results shown that
Geometric mean values for 11 fat-soluble and 6 water-soluble individual antioxidants,
antioxidant index and 3 macronutrients were virtually the same when comparing all cases (n
= 748) to self-reported cases only (n = 450). For patients diagnosed with Grade II and Grade
III histology, moderate (915.8-2118.3 mcg) intake of fat-soluble lycopene was associated
with poorer survival when compared to low intake (0.0-914.8 mcg), for self-reported cases
only. High intake of vitamin E and moderate/high intake of secoisolariciresinol among Grade
III patients indicated greater survival for all cases. In Grade IV patients, moderate/high intake
of cryptoxanthin and high intake of secoisolariciresinol were associated with poorer survival
among all cases. Among Grade II patients, moderate intake of water-soluble folate was
associated with greater survival for all cases; high intake of vitamin C and genistein and the
[9]
highest level of the antioxidant index were associated with poorer survival for all cases.The
associations observed in our study suggest that the influence of some antioxidants on survival
following a diagnosis of malignant glioma are inconsistent and vary by histology group.
Further research in a large sample of glioma patients is needed to confirm/refute our results10.
A randomized controlled trial was conducted on Antioxidant vitamins supplementation
and mortality, in head and neck cancer patients. The objective was to verify long-term
supplementation with high-dose antioxidant vitamins, especially vitamin E (α-tocopherol), may
increase all-cause mortality. With α-tocopherol (400 IU/day) and β-carotene (30mg/day)
supplements among 540 head and neck cancer patients treated by radiation therapy. The
supplements were given during radiation therapy and for 3 additional years. Results concur
with previous reports to suggest that high-dose vitamin E could be harmful. Conducted a
multicenter, double-blind, placebo-controlled, randomized chemoprevention trial with αtocopherol and β-carotene supplements among patients treated by radiation therapy for head
and neck cancer. During the recruitment period, 1,151 new patients with stage I or II squamous
cell carcinoma of the head and neck were treated in the participating radiation oncology
centers. Of these 1,151, 15% refused to participate and 38% were ineligible. The remaining
47% (n = 540) were eligible and consented to be enrolled. The baseline characteristics of the
273 and 267 patients randomly assigned to the supplement and placebo arms, respectively,
were similar in the 2 groups. The compliance with the prescribed supplementation was
excellent throughout the trial. The result shown that the supplement arm, the average
compliance, assessed by capsule count, was 90% during radiation therapy and 88, 84 and 80%
during the 1st, 2nd and 3rd years after the end of radiation therapy, respectively. In the placebo
arm, these figures were 89, 86, 83 and 80%, respectively11.
A pilot study was conducted on Improved Survival in Patients with End-stage Cancer
Treated with Coenzyme Q10 and Other Antioxidants. The objective was to evaluate the
survival of patients with end-stage cancer who received supplements of coenzyme Q10 and a
[10]
mixture of other antioxidants (e.g. vitamin C, selenium, folic acid and β-carotene). During a
period of 9 years, 41 patients who had end-stage cancer were included. Forty patients were
followed until death and one patient was lost to follow-up and presumed dead. Primary
cancers were located in the breast, brain, lungs, kidneys, pancreas, oesophagus, stomach,
colon, prostate, ovaries and skin. The median predicted survival time was calculated from
Kaplan-Meier curves for each patient at inclusion. The result shown that Median predicted
survival was 12 months (range 3 - 29 months), whereas median actual survival was 17
months (1 - 120 months), which is > 40% longer than the median predicted survival. Mean
actual survival was 28.8 months versus 11.9 months for mean predicted survival. Ten
patients (24%) survived for less time than predicted, whereas 31 (76%) survived for longer.
The study concludes that treatments were very well tolerated with few adverse effects12.
A systematic review and meta-analysis was conducted on antioxidant supplements for
prevention of gastrointestinal Cancers at Dimitrinka Nikolova. The objective was to establish
whether antioxidant supplements reduce the incidence of gastrointestinal cancer and
mortality. Outcomes were analyzed with fixed-effect and random-effects model metaanalyses and were reported as relative risk with 95% CIs. The result was 14 randomized trials
(n=170 525). Trial quality was generally high. Heterogeneity of results was low to moderate.
Neither the fixed-effect (relative risk 0·96, 95% CI 0·88–1·04) nor random-effects meta
analyses (0·90, 0·77–1·05) showed significant effects of supplementation with -carotene,
vitamins A, C, E, and selenium (alone or in combination) versus placebo on esophageal,
gastric, colorectal, pancreatic, and liver cancer incidences. In seven high-quality trials (n=131
727), the fixed-effect model showed that antioxidant significantly increased mortality (1·06,
1·02–1·10), unlike the random-effects meta-analysis (1·06, 0·98–1·15). Low-quality trials
showed no significant effect of antioxidant supplementation on mortality. The difference
between the mortality estimates in high-quality and low-quality trials was significant
(Z=2·10, p=0·04 by test of interaction).carotene and vitamin A (1·29, 1·14–1·45) and [11]
carotene and vitamin E (1·10, 1·01–1·20) significantly increased mortality, whereas carotene alone only tended to increase mortality (1·05, 0·99–1·11). The study concludes that
in four trials selenium showed significant beneficial effect on the incidence of gastrointestinal
cancer13.
A case control study conducted on Nutrition and cancer in Uruguay. The objective
was to examine the protective role of dietary antioxidants (carotenoids, vitamin C, vitamin E,
glutathione, and flavonoids) in lung cancer risk, involving 541 cases of lung cancer and 540
hospitalized controls was carried out. The result shown that carotenoids and vitamin E were
associated with significant reductions in risk of lung cancer (OR = 0.43, 95% CI = 0.29-0.64
for total carotenoids and OR = 0.50, 95% CI = 0.39-0.85 for vitamin E). A joint effect for
high vs. low intakes of b-carotene and glutathione was associated with a significant reduction
in risk (OR = 0.32, 95% CI = 0.22-0.46). The study concluded that dietary antioxidants are
associated with a significant protective effect in lung carcinogenesis and that the inverse
association for glutathione14.
A Systematic review of trials and meta-analysis was conducted on Antioxidants
Vitamin C and Vitamin E for the Prevention and Treatment of Cancer. The objective was to
evaluate the evidence of the supplements vitamin C and vitamin E for treatment and
prevention of cancer. Thirty-eight studies showed scant evidence that vitamin C or vitamin E
beneficially affects survival. The researcher identified only 3 studies that reported
statistically significant beneficial results: vitamin C was found to be beneficial in a single
trial of bladder cancer and vitamin E increased survival in patients with advanced cancer.
The result shown that in analyses of 6 individual cancers, the prevention of prostate cancer
in subjects treated with α-tocopherol was statistically significant (RR=0.64, 95% CI: 0.44,
0.94).A study concludes that dietary antioxidant is a substance in foods that significantly
decreases the adverse effects of reactive species, such as reactive oxygen and nitrogen
species, on normal physiological functions in humans15.
[12]
A case control study conducted on Antioxidants and breast cancer risk- a populationbased in Canada Centre for Chronic Disease Prevention and Control, Public Health Agency of
Canada. The objective was to assess the association between antioxidants and breast cancer
risk in a large population. The study population included 2,362 cases with pathologically
confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal) and 2,462
controls in Canada. The result was compared with subjects with no supplementation, 10 years
or longer supplementation of zinc had multivariable-adjusted odds ratios (OR) and 95%
confidence intervals (CI) of 0.46 (0.25-0.85) for premenopausal women, while
supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E
and zinc had multivariable-adjusted ORs (95% CIs) of 0.74 (0.59, 0.92), 0.58 (0.36, 0.95), 0.79
(0.63-0.99), 0.75 (0.58, 0.97), and 0.47 (0.28-0.78), respectively, for postmenopausal women.
The Concludes that supplementation of zinc in premenopausal women, and supplementation of
multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for
10 or more years may protect women from developing breast cancer16.
A study was conducted on potential anticancer properties of grape antioxidants in
department of Nutrition and Food Science, Wayne State University, Detroit, USA. Dietary
intake of foods rich in antioxidant properties is suggested to be cancer protective. Foods rich
in antioxidant properties include grape (Vitis vinifera). The composition and cancerprotective effects of major phenolic antioxidants in grape skin and seed extracts are discussed
in this review. Interestingly, some of these activities were also demonstrated in animal
models. However, in vivo studies have demonstrated inconsistent antioxidant efficacy.
Nonetheless, a growing body of evidence from human clinical trials has demonstrated that
consumption of grape, wine and grape juice exerts many health-promoting and possible anticancer effects. Thus, grape skin and seed extracts have great potential in cancer prevention
and further investigation into this exciting field is warranted17.
[13]
To assess the efficacy of a combination of these micronutrients in reducing the
incidence of recurrent adenomas in subjects on post-polypectomy endoscopic follow-up, a
double-blind placebo-controlled randomized trial was started in Italy in 1988. A total of 411
patients were randomized to receive either an active compound (200 μg selenium, 30 mg
zinc, 2 mg vitamin A, 180 mg vitamin C, 30 mg vitamin E) or a placebo daily for 5 years. Of
them, 330 had follow-up colonoscopy (164 in the intervention and 166 in the placebo group).
The results shown that after a median follow-up of 4 years (range 1-15 years), 100 patients
had recurrence: 38 in the intervention and 62 in the placebo arm. The 15-year cumulative
incidence of recurrence was 48.3 % in the intervention and 64.5 % in the placebo arm
(HR = 0.59; log-rank P = 0.009). A 39 % reduction of the risk of recurrence was observed in
the intervention compared to the placebo group (adjusted HR = 0.61; 95 % CI 0.41-0.92): the
risk reduction was similar for small tubular (adjusted HR = 0.61; 95 % CI 0.37-0.99) and
advanced adenomas (adjusted HR = 0.50; 95 % CI 0.24-1.01). the study concludes that our
study showed a statistically significant effect of antioxidant supplementation on adenoma
recurrence. Further clinical trials are needed to address the role of antioxidants in subgroups
of subjects at increased risk for colorectal cancer18.
The study was conducted on Melatonin and cancer: current knowledge and its
application to oral cavity tumours. An extensive review of the research literature was
conducted using PubMed, Science Direct, ISI Web of Knowledge, and the Cochrane base.
The results shown that this study highlights the growing importance of MLT in the prognosis
and treatment of certain tumours, including epidermoid carcinoma in the oral cavity.
Moreover, it opens up a highly original, encouraging line of research in the field of tumours.
The study concludes that MLT contributes to protecting the oral cavity from tissue damage
caused by receptor action. Experimental evidence suggests that it may be useful in the
treatment and prognosis of tumour processes in the oral cavity19.
