Pharynx
Pharynx is the curve
area of the back of the mouth, located between esophagus and trachea
connecting the nasal and oral cavities to the larynx. Its functions is
to provide a passageway for respiratory and digestive tracts. In the
United States in 2010 alone, according to National cancer Institute,
there were 12,660 new cases of pharyngeal cancer, resulting in deaths of
2,410 patients
Pharynx Cancer or pharyngeal cancer
Pharynx Cancer is originated in tissue of the pharynx and classified
1. The nasopharynx (the upper part of the throat behind the nose)
Cancer
of the pharyngeal most commonly begins with malignant cells that line
the nasopharynx, including nasal passages and auditory tubes join the
remainder of the upper respiratory tract.
2. The oropharynx (the middle part of the pharynx)
Cancer
of the oropharynx also begins with the malignant cells that line the
oropharynx, including the base of the tongue, the tonsils, the soft
palate.
3. The hypopharynx (the bottom part of the pharynx)
Cancer
of the hypopharynx most commonly begins with the malignant squamous
cell that line the hypopharynx where the area of the larynx and
esophagus meet. 90% of oropharyngeal neoplasms are squamous cell
carcinoma.
Types of Foods to prevent and treat Pharynx Cancer or pharyngeal cancer
1. Green tea
In a study of a total of 20,550 men and 29,671 women aged 40-79 years, without any history of oral and pharyngeal cancer showed that for women, the HRs of oral cancer for green tea
consumption of 1-2, 3-4, and 5 or more cups per day were 0.51 (95% CI:
0.10-2.68), 0.60 (95% CI: 0.17-2.10), and 0.31 (95% CI: 0.09-1.07),
respectively, compared with those who drank less than one cup per day (p
for trend, 0.08). For men, no such trends were observed(1).
2. Brussel sprouts, beets and broccoli
Folate found abundantly in Brussel sprouts, beets and broccoli. In the-control study, conducted in Italy and French-speaking Switzerland, included 749 patients with incident cancer of the oral cavity and pharynx, and 1772 hospital controls with acute, non-neoplastic conditions, indicated that folate have exerted a protective role of folate against oral and pharyngeal carcinogenesis.
Compared with low folate intake, a consistent reduction in risk was
already observed from intermediate levels of intake, suggesting that cancer risk may be related to relative folate deficiency(2).
3. Diet diversity
In the study of 805 patients with histologically confirmed incident cancers of the oral
cavity and pharynx, and controls of 2,081 patients admitted for
acute, non-neoplastic diseases, unrelated to tobacco or alcohol
consumption, indicated that a significant inverse association was observed with total diet
diversity. The multivariate odds ratio (OR), adjusted for education,
tobacco and alcohol, was 0.78 (95% confidence interval, CI 0.61-0.98)
for subjects in the highest tertile of diversity. Inverse relations were
found also for diversity within vegetables (OR = 0.62; 95% CI
0.49-0.78) and fruits (OR = 0.67; 95% CI 0.53-0.86)(3).
4. Turmeric
In the study to investigate the mechanism underlying the curcumin-induced apoptosis of nasopharyngeal carcinoma (NPC) cell line NCE cells, indicated that Several evidences of apoptosis were obtained from curcumin-treated
NCE cells by acridine orange and ethidium bromide stains,
ultrastructure identification, DNA fragmentation assay and TUNEL
staining. And the mean TUNEL-positive rates increased significantly at
the 3 different time points (12 h, 24 h and 48 h; 25.6%, 40.3% and
54.5%, respectively). In the curcumin-treated-groups,
delta psi m altered significantly and the positive rates increased in a
time-dependent manner. At the 3 different time points, the mean
positive rates were 26.8%, 42.3% and 68.2%, respectively. When caspase-3
activity was detected, 80.5% cells presented proteases activities after
12 h incubation with curcumin. Western Blot analysis showed that cytoplasmic cytochrome C increased significantly after incubation with curcumin. Flow cytometry and RT-PCR analysis showed that curcumin could up-regulate the Fas expression in time-depended manner , the positive rates of Fas protein increased from 33.6% to 89.9%(4).
