RE: From National Cancer Institute on HPV

[Guest guest]

Is uncanny in this morning's paper is an article. About HPV and how it is

definitely linked to cervical cancer.

From what I have read whether HPV ''causes " colon cancer is not verified

as of yet. Jolene

From National Cancer Institute on HPV

HPV Found in Half of Patients with Colorectal Cancer

Human papillomavirus (HPV) infection was found in more than half of

patients

with colorectal cancer, an NCI study reported in the April 15 Clinical

Cancer Research.

Researchers in the HIV and AIDS Malignancy Branch of NCI's CCR found that

28

of 55 (51 percent) of the colorectal cancer patients studied were positive

for HPV based on examination of samples from tumors and adjacent tissues.

Colorectal tissue from 10 control individuals, who didn't have colorectal

cancer,

were all negative, they noted.

The findings confirm previous controversial studies linking HPV with

colorectal cancer, but the NCI researchers were careful to avoid the

cross-contamination of tissue samples in the detection that may have

affected earlier

research.

Dr. Zhi-Ming Zheng, principal investigator in the study, explained the

precautions taken: " All samples of normal tissues taken from healthy

subjects

along with counterpart tumor and tumor-adjacent tissues from colon cancer

patients had to be examined in a blinded manner, using three separate

nested

polymerase chain reactions, each targeting a different region (L1, E6, and

E2) of

the virus genome. " A positive sample had to be confirmed in multiple

repeats to

be considered a real positive for HPV, he added.

Dr. Zheng addressed the implications of the study: " Establishing a firm

relationship between HPV infection and the development of colorectal cancer

will

require further research. However, it is quite likely that diseases caused

by

HPV infection will soon become preventable by vaccination. If this study is

confirmed and a substantial proportion of colorectal cancers are ultimately

found to be etiologically associated with HPV infections, this would help

us

to further understand the oncogenesis of colorectal cancer and might change

our views on its prevention and treatment. "

>>>HPV Found in Half of Patients with Colorectal Cancer >>>

Ok, now this makes me wonder...the cervical cancer vaccine that they have

approved is actually a vaccine against this HPV16 (there are many more with

different numbers but this one seems to be the one causing most cervical

cancers)....will this cause a backdoor effect of possible reducing the number of

colorectal cancer cases???

Wouldn't that be wonderful????

You know, sometimes that happens. They discover something for one thing, and it

actually works on something else too.

It is my understanding that this vaccine has to be given to young girls (and

boys) before they become sexual active. So it will take another generation

before we will know, I suppose.

That could all be but it bears a lot more testing to actually prove

the connection. We can pray for our children and grandchildren.. Jolene
