Since the 1980s, a small but steady trickle of
research (mostly non-U.S.) has implicated human papillomaviruses as a
cause of lung
cancer. HPV
DNA has been detected in over 21.7% of non-small cell lung cancers.
It was not established that HPV causes 100% of cervical cancers
until 1999, so the prevalence of HPV is probably underestimated in
these early studies. If HPV is
the true cause of only 20% of lung cancers, this would equal over
30,000 US cases, or ten times the number of pretended secondhand smoke
deaths, annually. This is also nearly three times more than the
approximately 12,000 (CDC) new cervical cancers in the U.S.! Because
smokers and passive smokers are more likely to have been exposed to
this virus, the anti-smokers' studies, which are based on nothing but
lifestyle questionnaires, automatically falsely blame the extra lung
cancers cancers caused by HPV on smoking and passive smoking. The
health establishment has officially
ignored the implications of this research, including the Surgeon
General, the US Environmental Protection Agency, and the California
EPA, in their ETS reports on smoking and secondhand smoke. Therefore,
these officials are guilty of
scientific
fraud.

2006 Apr;15(4):883-888. In 36 lung carcinomas (14 squamous cell
carcinomas, 13 adenocarcinomas, and 9 small cell carcinomas), from
Colombia, Mexico and Peru, PCR using GP5+/GP6+ primers combined with
Southern blot hybridization found the HPV genome in 10 (28%) of 36
cases. HPV-16 (7 cases) was the most common, followed by HPV-18 (2
cases) and HPV-33 (1 case). HPV-16 was more frequently found among
female than male cases (P=0.008) but was not detected in any
adenocarcinoma cases.
Different human papillomavirus 16/18 infection in Chinese non-small
cell lung cancer patients living in Wuhan, China. Y Fei, J Yang, WC
Hsieh, JY Wu, TC Wu, YG Goan, H Lee, YW Cheng. Jpn J Clin Oncol 2006
May;36(5):274-279. "the rates of HPV 16 and/or 18 infections in
patients with lung tumors [73] were significantly higher than in 34
non-cancer control subjects (26.0 versus 2.8% for HPV 16, P = 0.030;
23.3 versus 5.7% for HPV 18, P = 0.031; 27.7 versus 5.9% for HPV 16 or
18, P = 0.003) with a similar infection frequency of HPV 16 and 18
types in lung tumors. This result indicated that HPV 16/18 infection
may be associated with lung cancer development in Chinese patients from
Wuhan, China. Further statistical analyses revealed that HPV 16 or 18
infection was not correlated with any clinico-pathological parameter
studied, including age, gender, smoking status, tumor type,
tumor stage
and tumor grades. Interestingly, smoking and male patients had a higher
prevalence of HPV 16, although not reaching a statistical significance,
compared with non-smoking and female patients, respectively (33.3% for
smokers versus 20.0% non-smokers; 33.3% for male versus 17.6% for
female)." "Our recent report showed that there was an approximately 70%
concordance between HPV 16 DNA detection in peripheral blood cells and
lung tumor tissues of lung cancer patients. In addition, about 80% of
HPV infected-female lung cancer patients from Japan and Norway had a
history of cervical intraepithelial neoplasia. Moreover, our
preliminary data showed an identical DNA sequence of HPV 16/18 E6, E7
and L1 in peripheral blood lymphocyte, Pap smear and lung tumor from
the same lung cancer patients. These results support the possibility
that HPV might have originated from the cervix and then transmitted to
lung tissues through blood circulation."

(29%) out of 69 lung carcinomas (LCs) in Chile, by PCR and Southern

cases, was the most frequently detected HPV genotype determined by DNA
sequencing. HPV-16 E2/E6 ratio, estimated from real-time PCR analysis,
was much lower than the unity, suggesting that at least a partial
HPV-16 genome was integrated in all but one HPV-16-positive SQCs. The
remaining one case was suspected to have only episomal HPV-16. Although
the viral load was low in most of the LCs, a case showed the HPV-16
copy number as high as 8479 per nanogram DNA, which was even a few
times higher than the minimum viral load of seven cervical carcinomas
(observed viral load: 3356-609 392 per nanogram DNA)."

The American
Cancer Society's propaganda circus: Dr.Arash Rezazadeh and
colleagues from the University of Louisville,
Kentucky, USA. Abstract No. 124PD; Friday 25th April, 09:50, presented
at the 1st European Lung Cancer Conference, jointly organized by the
European Society for Medical Oncology (ESMO) and the International
Association for the Study of Lung Cancer (IASLC) in Geneva,
Switzerland. Six of 23 lung cancers, all from smokers, were positive
for HPV,
one of which was a metastasized cervical cancer. Of the remaining 5
virus-positive samples, two were HPV type 16, two were HPV type 11 and
one was HPV type 22. An accompanying study found measles virus in more
than half of 65 non-small cell lung cancers. Both studies are to be
published
in the Journal of Thoracic Oncology, www.jto.org. This is the first
known mention of HPV involvement in lung
cancer in the U.S. mass media. The story was spin-doctored by the
American Cancer Society, because the media are nothing but their
corrupt
lie-spewing puppets who would never dream of uttering a peep without
the approval of their masters. CBS News posted a WebMD article on April
23, 2008, whose lead sentence was nothing but the American Cancer
Society's stock anti-smoking propaganda, which was likewise parroted by
all the rest. "Dr. Len Lichtenfeld, deputy chief medical officer of the
American Cancer Society, described both research efforts as
'interesting.' But he cautioned that more research needs to be done on
each front.... 'But I think the HPV study is the more interesting of
the two,' Lichtenfeld added, 'since HPV is obviously already implicated
in other cancers. But this is a small study, and it only suggests a
possible link to lung cancer without answering a lot of questions. I
would like to know, for example, whether patients who are not smokers
but who develop lung cancer have a higher rate of HPV. But for now, I
would not yet conclude that HPV increases risk, nor would I tie the HPV
vaccine to any risk.'" And what about those 50-plus other studies which
preceded it, several of which did include non-smokers? The Cancer
Society didn't bother to wait for 50 studies before proclaiming its
absolute certainty that secondhand smoke causes lung cancer! (Possible
Viral Links to Lung Cancer Risk Uncovered. By Alan Mozes. U.S. News and
World Report, April 25, 2008.) "'We think HPV has a role as a
co-carcinogen which
increases the risk of cancer in a smoking population,' Rezazadeh said
in a statement." This deceitful statement also ignores the studies
showing that HPV also has a major role in non-smokers' lung cancer.
"Though the study is the first to note
the combined effects of smoking and HPV on the lungs, doctors have
known for a while that women who smoke and contract HPV are more likely
to develop cervical cancer than nonsmokers, said Dr. Lauren F.
Streicher, an OB/GYN and professor at Northwestern Medical School."
This is a lie, because this study only evaluated the rate of HPV
infection in lung cancers from smokers and there was no comparison
group of any kind. "'Smoking plays a key role in the rate of conversion
to malignancy in cervical cancer too,' she said. 'Seventy to 80 percent
of women are exposed to HPV, but less than 1 percent of women get
cervical cancer. We know lesions on the cervix are more likely to
become cancerous in smokers.'" This is a lie, too. The American Cancer
Society and its lackeys deliberately use defective studies in order to
falsely blame smoking for cervical cancer. For example, they only look
at one strain of HPV, while ignoring the others that are also known to
cause cervical cancer, and also the fact that infection by multiple
strains is more likely to result in cancer than infection by a single
strain; and they ignore differences in the amount of exposure to the
infection, all so that they can purposely exploit the socioeconomic
differences between smokers and nonsmokers to manufacture their
fraudulent claim that smoking causes cervical cancer! And the filth in
the media eagerly spew their lies, and embrace their scientific fraud,
and refuse to allow any criticism. (Study Links HPV to Lung Cancer. By

Human papillomavirus type 16 and 18 infection is associated with
lung cancer patients from the central part of China. Y Wang, A Wang, R
Jiang, H Pan, B Huang, Y Lu, C Wu. Oncol Rep 2008 Aug;20(2):333-239. In
313 fresh lung tumor specimens tested for HPV with polymerase chain
reaction and non-isotopic in situ hybridization, "44.1% of (138/313)
non-small cell lung carcinoma (NSCLC) samples were positive for HPV
detection, while 4.2% (4/96) of lung benign controls were positive for
HPV 16 and 18 DNA. HPV infection was significant between lung squamous
cell carcinoma and adenocarcinoma
as well as smoking
and non-smoking patients. In HPV-positive lung cancer tissues,
abnormal p53 protein accumulation was seen in 97 of the 138 carcinomas
(70.3%) and expression of pRb in 54 of the 138 carcinomas (39.1%).
There was an obvious relationship between the presence of papilloma
viral DNA and abnormal p53 protein accumulation and pRb depletion. Cell
proliferation and apoptosis were correlated with HPV infection in NSCLC
samples."

Oncol Rep 2009 Jun;21(6):1627-1632. "72 lung squamous cell carcinomas,
37 lung adenocarcinomas and 71 non-cancer controls, were analyzed by
INNO-LIPA Genotype polymerase chain reaction (PCR) and real-time PCR

carcinoma samples, 16.2% (6/37) of adenocarcinoma, and 22.5% (16/71) of
non-cancer controls were HPV DNA positive. The risk of lung squamous
cell carcinomas was 3.5 times higher among people HPV-positive (odds
ratio 3.5, 95% CI 1.6-7.3, p<0.001) compared with the HPV- negative
population. Adjusted by smoking status, the risk of lung squamous cell
carcinomas was 3.5 times higher among people HPV-positive (odds ratio
3.5, 95% CI 1.7-7.5, p=0.001) compared with the HPV-negative
population. The risk of lung squamous cell carcinomas was 16.9 times
higher for patients with positive HPV-16 (odds ratio 16.9, 95% CI

LATEST REVIEW: Incidence
of human papilloma virus in lung cancer. F Klein, WF Amin Kotb, I
Petersen. Lung Cancer 2009 Jul;65(1):13-18. "53 publications reporting
on 4508 cases were reviewed and assessed for the following parameters:
continent and region of the study, number of cases, detection method,
material type, HPV type, histological subtype and number of the
HPV-positive cases. Overall, the mean incidence of HPV in lung cancer
was 24.5%. While in Europe and the America the average reported
frequencies were 17% and 15%, respectively, the mean number of HPV in
asian lung cancer samples was 35.7%. There was a considerable
heterogeneity between certain countries and regions. Particular high
frequencies of up to 80% were seen in Okinawa (Japan) and Taichung
(Taiwan). However, there were also discrepant results within the same
region pointing to methodological differences and the need for
validation. All lung cancer subtypes were affected and especially the
high risk types 16, 18, 31 and 33 as well as the low risk types 6 and
11 were found, the later mainly in association with squamous cell
carcinomas. The data suggest that HPV is the second most important
cause of lung cancer after cigarette smoking and strongly argues for
additional research on this issue."
COMMENT: We can expect the incidence of HPV in lung cancer to increase, because not all studies looked for all the types of HPV implicated, and because of improvements in methodology. The issue which most urgently needs to be addressed is that studies which are based on nothing but lifestyle questionnaires exploit different rates of HPV exposure between smokers, passive smokers, and non-passive smoke-exposed non-smokers to falsely blame smoking and passive smoking for lung cancer that is actually caused by HPV. Furthermore, it is necessary to address the fact that the American Cancer Society and its clones have deliberately and systematically used defective studies of this type in order to push their political agenda of outlawing tobacco - an agenda which the politically-connected elite have been pursuing since the days of Rev. George Trask.
Human papillomavirus 16/18 E6 oncoprotein is expressed in lung
cancer and related with p53 inactivation. YW Cheng, MF Wu, J Wang, KT
Yeh, YG Goan, HL Chiou, CY Chen, H Lee. Cancer Res 2007 Nov
15;67(22):10686-10693. 122 lung tumors. "Western blotting showed that
E6 protein was indeed expressed in HPV16-infected cells and a lower
level of p53 protein was observed in E6-positive cells compared with
E6-negative cells. Moreover, the levels of p21(WAF1/CIP1) and mdm2 mRNA
in E6-positive cells were lower than in E6-negative cells. The
interaction of E6 with p53 protein was revealed by immunoprecipitation
assay showing that p53 could be inactivated by E6 protein. Conversely,
p53 proteins and p21(WAF1/CIP1) and mdm2 mRNA expressions were restored
in E6-knockdown cells by RNA interference compared with control cells.
These results reveal that HPV16/18 E6 may be partially involved in p53
inactivation to down-regulate p21(WAF1/CIP1) and mdm2 transcription. In
conclusion, HPV16/18 E6 is indeed expressed in HPV DNA-positive lung
tumors and is involved in p53 inactivation to contributing to
HPV-mediated lung tumorigenesis."

elucidate the roles of HPV infection in lung tumorigenesis.... Lung
tumors (70.9% and 57.0%) had positive IL-6 and Mcl-1 immunostainings,
respectively. Significant correlation between IL-6 and Mcl-1 expression
were observed (P < 0.0001). Both IL-6 and Mcl-1 expression were
significantly associated with HPV 16/18 infection (P = 0.014 and P =
0.004, respectively). IL-6 and Mcl-1 protein levels were not only
elevated in HPV 16/18 E6- and E7-transfected A549 cells but also in

Human telomerase reverse transcriptase activated by E6 oncoprotein is required for human papillomavirus-16/18-infected lung tumorigenesis. YW Cheng, TC Wu, CY Chen, MC Chou, JL Ko, H Lee. Clin Cancer Res 2008 Nov 15;14(22):7173-7179. In 135 lung tumors, "hTERT mRNA levels in E6-positive tumors, which were prevalent in females, nonsmokers, and adenocarcinomas, were significantly higher than in E6-negative tumors. In addition, hTERT mRNA levels in early tumors (stage I) were greater than levels in advanced tumors (stages II and III). Chromatin immunoprecipitation assay showed that Sp1 cooperated with c-Myc to activate hTERT transcription in TL-1 cells, which was similar to the SiHa cells. The telomerase activity of the TL-1 cells decreased concomitantly with the transfection of various doses of E6- or hTERT-RNAi. A soft-agar assay showed that the oncogenic potential of TL-1 cells was significantly reduced after being transfected with E6-RNAi. Moreover, a colony of TL-1 cells could not form after transfection with hTERT-RNAi."

Identification of a novel polyomavirus from patients with acute
respiratory tract infections. AM Gaynor, MD Nissen, DM Whiley, IM
Mackay, SB Lambert, G Wu, DC Brennan, GA Storch, TP Sloots, D Wan. PLoS
Pathog 2007;3(5): e64. The virus was found in 43 / 2,135
patients with acute respiratory disease, including pneumonia. 86% were
under 3 years old. "Much of the interest in polyomaviruses and SV40 in
particular derives from the transforming properties carried by the
early transcriptional region of the viral genome that encodes for the
small T antigen (STAg) and and large T antigen (LTAg). T antigen is
capable of binding both p53 and Rb proteins and interfering with their
tumor suppressor functions. The early region alone is sufficient to
transform established primary rodent cell lines and in concert with
telomerase and ras transforms primary human cells... Since the T
antigen of WU is predicted to have transforming properties by analogy
to other polyomavirus T antigens, one question currently under
investigation is whether a subset of human tumors may be associated
with WU."

was found by PCR in 6 (1%) of 637 nasopharyngeal aspirates and in 1
(0.5%) of 192 fecal samples but was not detected in sets of urine and
blood samples. Since polyomaviruses have oncogenic potential and may
produce severe disease in immunosuppressed individuals, continued
searching for the virus in different medical contexts is important."
"There are putative binding sites for p53, as well as the Rb family of
tumor suppressor proteins, in the LT antigen of KIPyV, which indicates
that a role for this virus in tumorigenesis cannot be excluded."

China, "The positive rates of EBV infection in squamous cell carcinoma,
adenocarcinoma, small cell carcinoma and large cell carcinoma were
35.9%, 31.6% 31.0%, 1/2, respectively."
"General interest in lung cancer developed considerably later in the
United States than it did in Europe but cases were described (37) at
the Massachusetts General Hospital in 1842 and 1850. Articles
contributed by Lehlbach (38) in 1870 and by Loomis (39) in 1876 showed
considerable familiarity with the disease. Delafield (40), the
pathologist at Roosevelt Hospital, was well acquainted with primary
lung cancer as early as 1868 as evidenced by his autopsy records. In
the later decades of the 19th century the number of American articles
increased including contributions by Pepper (41), Van Giesen (42),
Ripley (43), Kemper (44), Janeway (45), Holland (46), Hodenpyl (47),
and LeCount (48). On December 18, 1880, the Medical Record commented
editorially that lung cancer would continue to interest pathologists
despite the lack of specific treatment. The most important American
article on lung cancer in the 19th century appeared in the New York
Medical Journal on February 8, 1896. The author was Adler (49) whose
monograph on the subject in 1912 has since become a medical classic. In
the 1896 article, Adler repeatedly emphasized that lung cancer was not
a rare disease in the United States but was rarely diagnosed. He
urged physicians to become more familiar with its clinical
manifestations and pathologists to do more meticulous work so as to
better recognize the disease at autopsy." (Smoking and Disease:
