Results from a cervical cancer screening program in Samsun, Turkey.

BACKGROUND: Cervical cancer is a preventable disease. This study aimed to share the results of the national cervical cancer screening program performed in primary health care institutions in Samsun between 2015 and 2019. METHODS: Women aged 30-65 years who were screened for cervical cancer in screening centers of Samsun between January 01, 2015, and December 31, 2019, were included in this descriptive study. The data were obtained from the automation program of the "National Human Papilloma Virus (HPV) Laboratory Application" used by the Provincial Directorate of Health Cancer Unit through filtering the completion time of the tests, and all results were evaluated without sampling. Thus, data were presented using descriptive statistics. RESULTS: The mean age of 89,302 women included in the cervical cancer screening program was 45.9 ± 9.0 years. Of the samples obtained from the participants, 1.0% were determined as insufficient material, 94.1% as HPV-negative, and 4.9% as HPV-positive. The most common HPV genotypes were 16, 51, 31, and 52. Of the 4337 HPV-positive women, 74.7% of the pap smear results were negative (including infection, 36.5%), and the most common premalignant lesions were atypical squamous cells of undetermined significance in 7.1% and low-grade squamous intraepithelial lesions in 6.9%. HPV 16/18 was also observed in 31.7% of HPV-positive women. Seven hundred ninety-five women were referred to a specialist physician for further examination and treatment within the scope of the screening algorithm. CONCLUSION: Detecting HPV-positivity by reaching more women within the national cervical cancer screening program's scope is vital in fighting against this disease. The effectiveness of cancer screening programs should be increased by ensuring community participation through awareness activities.

Selenium atom on phosphate enhances specificity and sensitivity of DNA polymerization and detection.

DNA polymerization is of high specificity in vivo. However, its specificity is much lower in vitro, which limits advanced applications of DNA polymerization in ultrasensitive nucleic acid detection. Herein, we report a unique mechanism of single selenium-atom modified dNTP (dNTPαSe) to enhance polymerization specificity. We have found that both dNTPαSe (approximately 660 fold) and Se-DNA (approximately 2.8 fold) have lower binding affinity to DNA polymerase than canonical ones, and the Se-DNA duplex has much lower melting-temperature (Tm) than the corresponding canonical DNA duplex. The reduced affinity and Tm can destabilize the substrate-primer-template-enzyme assembly, thereby largely slowing down the mismatch of DNA polymerization and enhancing the amplification specificity and in turn detection sensitivity. Furthermore, the Se-strategy enables us to develop the selenium enhanced specific isothermal amplification (SEA) for nucleic acid detection with high specificity and sensitivity (up to detection of single-digit copies), allowing convenient detection of clinical HPV and COVID-19 viruses in the low-copy number. Clearly, we have discovered the exciting mechanism for enhancing DNA polymerization accuracy, amplification specificity and detection sensitivity by SEA, up to two orders of magnitude higher.

Antiviral activity of curcumin-nanoemulsion associated with photodynamic therapy in vulvar cell lines transducing different variants of HPV-16.

Vulvar intraepithelial neoplasia (VIN) is associated with human papillomavirus (HPV) infection. Curcumin is a natural bioactive compound with antineoplastic properties. The use of nanoparticles containing curcumin could allow a better performance of this compound in therapies. So, VIN biopsies were collected and HPV DNA detection was performed by PCR, positive samples were genotyped by Restriction Fragment Length Polymorphism (RFLP) and HPV-16 variants were determined by sequencing. HPV-16 positive vulva carcinoma cells (A431) were transduced with E-P and E-350G HPV-16 E6 variants. The viability of the transduced cells treated with nanoemulsions was determined by MTT assay. Besides, apoptosis was evaluated by enzymatic activity of Caspase-3/7. The cell viability assay showed that both the empty nanoemulsion (NE-V) and the nanoemulsion of curcumin (NE-CUR) had little effect on cell viability as compared to control cells. Additionally, we observed that cells irradiated in the presence of NE-CUR presented 90% of cell death. The apoptosis assay further revealed a significant increase in the activity of caspases 3 and 7 in A431 cells expressing both HPV-16 E6 variants after treatment with NE-CUR. Finally, we submitted the HPV transduced A431 cells to organotypic cultures and observed that the combination of treatments affected tissue architecture with evident signals of tissue damage. We concluded that nanoemulsions attain good biocompatibility, since no cytotoxicity was observed and NE-CUR associated with photoactivation showed promising results, leading to death only in cells subjected to irradiation. This drug delivery system associated with photodynamic therapy may become promising in the treatment of vulva lesions.

An ultrasensitive label free human papilloma virus DNA biosensor using gold nanotubes based on nanoporous polycarbonate in electrical alignment.

An impedimetric human papilloma virus (HPV) DNA biosensor based on gold nanotubes (AuNTs) in label free detection was materialized. The AuNTs decorated nanoporous polycarbonate (AuNTs-PC) template as biosensor electrode was fabricated by electrodeposition method. The single strand DNA (ss-DNA) probe was covalently immobilized onto the AuNTs-PC electrode. The hybridization of target sequences with the ss-DNA probe was observed by the electrochemical impedance spectroscopy (EIS). The biosensor showed high selectivity and could differentiate between the complementary, mismatch and non-complementary DNA sequences. The EIS measurements were matched to Randle's equivalent circuit. The negatively-charged HPV DNA oligonucleotides under external electric field were oriented in a preferred direction and the bio-sensing responses were intensified by controlling the immobilization and hybridization of the sequences on the AuNTs surface. The fabricated DNA biosensor under electric field amplification was stable up to six weeks and demonstrated 97% of its initial detection responses. The biosensor displayed the HPV DNA hybridization detection in very low concentrations in the linear response ranges of 0.01 pM-1 µM and was able to acquire a limit of detection (LOD) of 1 fM.

Conclusiones: Las condiciones técnicas y económicas existen en Chile para lograr una mejoría sustancial del CC: se sugiere el reemplazo del Papanicolaou por el examen de VPH; tamizaje cada cinco años con opción de autotoma; triaje con base en la tipificación de VPH 16/18 o Papanicolaou.

Abstract: Objective: To discuss cervical cancer (CC), Human Papilloma Virus (HPV), CC control program and propose alternatives for Chile. Materials and methods: We analyzed the national program of CC 1966-2015 and the clinical CC guideline 2015-2020; HPV prevalence in women and in cases of CC; HPV infection and serology; the self-vaginal sample; the accuracy and cost-effectiveness of screening with HPV versus Papanicolaou, and triage options among HPV-AR positives. Results: 600 women die of CC each year in Chile, mainly from low resources. Papanicolaou coverage is <70%; Papanicolaou sensitivity is much lower than HPV test. Change from Papanicolaou to HPV test is cost-effective. Since 2015, girls under 13 have been vaccinated against HPV. Conclusions: There are the technical and economic conditions for a substantial improvement of CC in Chile: replacement of the Papanicolaou by HPV; screening every five years, with the option of self-sampling, and triage based on HPV 16/18 or Papanicolaou typing.

Realgar, a traditional Chinese medicine, induces apoptosis of HPV16-positive cervical cells through a HPV16 E7-related pathway.

PURPOSE: In this study, we investigated the effect of Realgar on the apoptosis of HPV16-positive cervical cells in vitro. METHODS: The effect of Realgar on the apoptosis of HPV16-positive cervical cells was investigated by annexin V-fluorescein isothiocyanate/propidium iodide staining and growth inhibition assays using HPV16-positive cervical cancer cell line SiHa and HPV16-positive immortalized cervical epithelial cell line S12. The expression of genes was measured by real-time PCR, and the expression of corresponding proteins was detected by Western blotting. The adhesion and invasion of cells were detected by adhesion assay and Transwell invasion assay, respectively. RESULTS: The Realgar inhibited the proliferation and induced the apoptosis of SiHa and S12 cells in a dose- and time-dependent manner. The Realgar suppressed the expression of HPV16 E7 and caspase-3. The Realgar suppressed the adhesion and invasion of both cells. CONCLUSION: The Realgar induced apoptosis, inhibited the proliferation of HPV16-positive cell lines through a HPV16 E7-dependent pathway, and inhibited cell adhesion and invasion.

Microfluidic-Based Genosensor To Detect Human Papillomavirus (HPV16) for Head and Neck Cancer.

High-risk human papillomavirus (HPV) infection, mainly with HPV16 type, has been increasingly considered as an important etiologic factor in head and neck cancers. Detection of HPV16 is therefore crucial for these types of cancer, but clinical tests are not performed routinely in public health systems owing to the high cost and limitations of the existing tests. In this article, we report on a potentially low-cost genosensor capable of detecting low concentrations of HPV16 in buffer samples and distinguishing, with high accuracy, head and neck cancer cell lines according to their HPV16 status. The genosensor consisted of a microfluidic device that had an active layer of a HPV16 capture DNA probe (cpHPV16) deposited onto a layer-by-layer film of chitosan and chondroitin sulfate. Impedance spectroscopy was the principle of detection utilized, leading to a limit of detection of 10.5 pM for complementary ssDNA HPV16 oligos (ssHPV16). The genosensor was also able to distinguish among HPV16+ and HPV16- cell lines, using the multidimensional projection technique interactive document mapping. Hybridization between the ssHPV16 oligos and cpHPV16 probe was confirmed with polarization-modulated infrared reflection-absorption spectroscopy, where PO2 and amide I and amide II bands from adenine and thymine were monitored. The electrical response could be modeled as resulting from an adsorption process represented in a Freundlich model. Because the fabrication procedures of the microfluidic devices and genosensors and the data collection and analysis can be implemented at low cost, the results presented here amount to a demonstration of possible routine screening for HPV infections.

Increasing prevalence of human papillomavirus-positive oropharyngeal cancers among older adults.

BACKGROUND: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing among older adults. It is unknown whether these trends can be explained by human papillomavirus (HPV) and whether HPV-related tumors remain associated with an improved prognosis among older patients. METHODS: In a retrospective study of OPSCCs diagnosed from 1995 to 2013 at 2 National Comprehensive Cancer Network-designated cancer centers, p16 immunohistochemistry and in situ hybridization (ISH) for HPV-16, high-risk DNA, and/or E6/E7 RNA were performed. The median age at diagnosis was compared by p16 and ISH tumor status. Trends in age were analyzed with nonparametric trends. Survival was analyzed with the Kaplan-Meier method and Cox proportional hazards models. RESULTS: Among 239 patients, 144 (60%) were p16-positive. During 1998-2013, the median age increased among p16-positive patients (Ptrend = .01) but not among p16-negative patients (Ptrend = .71). The median age of p16-positive patients increased from 53 years (interquartile range [IQR] in 1995-2000, 45-65 years) to 58 years (IQR for 2001-2013, 53-64 years). Among patients ≥ 65 years old, the proportion of OPSCCs that were p16-positive increased from 41% during 1995-2000 to 75% during 2007-2013 (Ptrend = .04). Among all age groups, including older patients, a p16-positive tumor status conferred improved overall survival in comparison with a p16-negative status. CONCLUSIONS: The median age at diagnosis for HPV-related OPSCC is increasing as the proportion of OPSCCs caused by HPV rises among older adults. The favorable survival conferred by an HPV-positive tumor status persists in older adults. Cancer 2018;124:2993-9. © 2018 American Cancer Society.

Prevalence of high-risk human papillomavirus infection and cancer gene mutations in nonmalignant tonsils.

OBJECTIVES: To analyze the prevalence of high-risk HPV (human papillomavirus) and genetic alterations in nonmalignant tonsils. METHODS: We collected benign fresh tonsillar tissue specimens from 477 patients undergoing tonsillectomy because of chronic tonsillitis or tonsillar hypertrophy in 2012 (Group A, n=237) and in 2015 (Group B, n=240). Luminex xMAP technique served to detect E6/E7 DNA from 16 different high-risk HPV types. Tonsillar DNA and peripheral blood leukocyte DNA from the infected individuals were analyzed using Nimblegen SeqCap EZ Comprehensive Cancer Design panel. The panel targets 578 different genes that are relevant in carcinogenesis. HPV negative tonsillar specimens from age- and gender matched individuals were used as controls. All specimens harboring high-risk HPV were analyzed using fluorescence in situ hybridization (FISH). RESULTS: Five of 477 (1.0%) patients tested positive for the following HPV types: HPV16 (two cases), HPV52 (one case), HPV66 (one case), HPV52 and HPV68 (coinfection, one case). FISH analyses showed that the appearance of HPV in specimens infected with HPV 16 was episomal. Benign tonsils infected with high-risk HPV harbored mutations in EP300, NF1, PIK3CA, and RB1 which are considered relevant in the development of HPV-associated head and neck squamous cell carcinoma (SCC). CONCLUSIONS: The prevalence of high-risk HPV in nonmalignant tonsils is low. High-risk HPV positive tonsils harbored mutations in genes that are commonly altered in HPV-associated head and neck SCC. The role of these mutations in tonsillar carcinogenesis is an interesting target for future research.

High sensitivity, loop-mediated isothermal amplification combined with colorimetric gold-nanoparticle probes for visual detection of high risk human papillomavirus genotypes 16 and 18.

High-risk human papillomavirus (HR-HPV) causes cervical cancer. HPV16 and HPV18 are the most prevalent strains of the virus reported in women worldwide. Loop-mediated isothermal amplification (LAMP) is an alternative method for DNA detection under isothermal conditions. However, it results in a turbid amplified product which is not easily detected by the naked eye. This study aimed to develop an improved technique by using gold nanoparticles (AuNPs) attached to a single-stranded DNA probe for the detection of HPV16 and HPV18. Detection of the LAMP product by AuNP color change was compared with detection by visual turbidity. The optimal conditions for this new LAMP-AuNP assay were an incubation time of 20min and a temperature of 65°C. After LAMP amplification was complete, its products were hybridized with the AuNP probe for 5min and then detected by the addition of magnesium salt. The color changed from red to blue as a result of aggregation of the AuNP probe under high ionic strength conditions produced by the addition of the salt. The sensitivity of the LAMP-AuNP assay was greater than the LAMP turbidity assay by up to 10-fold for both HPV genotypes. The LAMP-AuNP assay showed higher sensitivity and ease of visualization than did the LAMP turbidity for the detection of HPV16 and HPV18. Additionally, AuNP-HPV16 and AuNP-HPV18 probes were stable for over 1year. The combination of LAMP and the AuNP-probe colorimetric assay offers a simple, rapid and highly sensitive alternative diagnostic tool for the detection of HPV16 and HPV18 in district hospitals or field studies.

Clinical implications of the HPV-16 infection & 7 beneficial effects of optimal dose of Vitamin D3 in safe, effective cancer treatment: Non-invasive rapid cancer screening using "Mouth, Hand & Foot Writing Form" of 40 participants during 150- minute workshop on the Bi-Digital 0-ring Test, in the 1st day of European Congress for Integrative Medicine, September 9-11, 2016 in Budapest.

During the 1st day of European Congress for Integrative Medicine held September 9-11, 2016, almost the entire 1st day was scheduled for the Bi-Digital O-Ring Test, which was originally developed by this author, & consists of 2 main parts for which a U.S. patent was issued in 1993. One is a non-invasive, detection of various molecules using very strong Electromagnetic Field (EMF) Resonance Phenomenon between 2 identical molecules with identical weight. Using this strong EMF Resonance Phenomenon, most molecules & microorganisms can be detected rapidly and non-invasively without directly contacting patients. We measured the HPV-16 infection of 70 participants non-invasively in the first 30 minutes, then screened cancers for 40 volunteers who completed one page "Mouth, Hand & Foot Writing Form," which took an average of 5∼10 minutes for each person to complete. Screening of 75 common cancers was made in 2-5 minutes for each patient. Analysis of 40 volunteers revealed 32 persons had some malignancies including 5 Anaplastic Astrocytomas of the L-brain, 3 Multiple Myelomas, 7 Hodgkin's Lymphomas, 8 Non-Hodgkin's Lymphomas, 2 rectum cancers (with chief complaints of worsening Irritable Bowel Syndrome). Although everyone had HPV-16 infections between about 6,000ng & 250ng, malignancy could not be found among those who had less than 1,200ng. Our individualized safe, effective and economical treatment of various cancers consists of optimal doses of Vitamin D3 with or without Taurine and/or PQQ depending on the positive synergetic compatibility among these 3 substances as normal parts of human tissue. The most serious 2 cases of rectum cancer with multiple metastasis, we confirmed very significant anti-cancer effects of their optimal doses of vitamin D3, which is increased to 800~1,000 I.U. (due to advanced cancer with multiple metastasis instead of the usual 400 I.U. for average adults). The unique 7 beneficial effects of optimal dose of Vitamin D3 (also Taurine or PQQ) include: 1) significant Anti-cancer effects without side effects; 2) marked decrease in DNA mutation as decreases in 8-OH-dG; 3) marked urinary excretion of Viruses, Bacteria, Fungi, & Toxic substances, including Asbestos & metals; 4) marked increase in Acetylcholine in the brain & the rest of the body; 5) marked increase in DHEA; 6) marked decrease in ß-Amyloid (I-42); 7) marked decrease in Cardiac Troponin I. Optimal dose of Vitamin D3 is clinically most important for cancer, ischemic heart, and memory problems. Optimal dose of Taurine is 150∼175mg and PQQ is 5-7.5mg and should be taken 3-4 times a day, depending on the patient. Medications and supplements including excessive Vitamin C (as well as multivitamins) but also inhibited optimal doses of Vitamin D3, Taurine & PQQ. Often coffee, drinks containing high Vitamin C content (e.g., some green tea & orange juice), & multivitamins as well as pain medicine (e.g., Oxycodone), strong EMF from cellular phones, and strong negative BDORT underwear often completely eliminate the above beneficial effects of Vitamin D3 and promote growth of cancer.

Hyperthermia Selectively Targets Human Papillomavirus in Cervical Tumors via p53-Dependent Apoptosis.

Human papillomavirus (HPV) is associated with cervical cancer, the third most common cancer in women. The high-risk HPV types 16 and 18 are found in over 70% of cervical cancers and produce the oncoprotein, early protein 6 (E6), which binds to p53 and mediates its ubiquitination and degradation. Targeting E6 has been shown to be a promising treatment option to eliminate HPV-positive tumor cells. In addition, combined hyperthermia with radiation is a very effective treatment strategy for cervical cancer. In this study, we examined the effect of hyperthermia on HPV-positive cells using cervical cancer cell lines infected with HPV 16 and 18, in vivo tumor models, and ex vivo-treated patient biopsies. Strikingly, we demonstrate that a clinically relevant hyperthermia temperature of 42 °C for 1 hour resulted in E6 degradation, thereby preventing the formation of the E6-p53 complex and enabling p53-dependent apoptosis and G2-phase arrest. Moreover, hyperthermia combined with p53 depletion restored both the cell-cycle distribution and apoptosis to control levels. Collectively, our findings provide new insights into the treatment of HPV-positive cervical cancer and suggest that hyperthermia therapy could improve patient outcomes.

Focal epithelial hyperplasia by human papillomavirus (HPV)-32 misdiagnosed as HPV-16 and treated with combination of retinoids, imiquimod and quadrivalent HPV vaccine.

Focal epithelial hyperplasia (FEH) or Heck's disease is a rare, benign and asymptomatic mucosal proliferation associated with human papillomavirus (HPV) infection, mainly with genotypes 13 and 32. We report a florid case of FEH in an 11-year-old Haitian girl with systemic lupus erythematosus receiving immunosuppressive therapy. Cryotherapy was previously performed on numerous occasions with no results. We decided to prescribe a non-invasive and more comfortable treatment. A combination of topical retinoid and imiquimod cream was well tolerated and led to an important improvement. The evidence of infection by HPV-16 detected by polymerase chain reaction (PCR) technique, prompted us to prescribe the quadrivalent HPV vaccine (types 6, 11,16 and 18). Subsequent PCR sequencing with generic primers GP5-GP6 and further BLAST comparative analysis confirmed that genomic viral sequence in our case truly corresponded with HPV-32. This molecular misdiagnosis can be explained by the similarity between genomic sequences of both HPV-16 and -32 genotypes. At the 1-year follow up, we observed total clinical improvement and no recurrences of the disease. Complete healing in this case may correspond to a potential action of topical retinoid, imiquimod and the cross-protection mechanism of the quadrivalent HPV vaccine.

Early Detection of Autism (ASD) by a Non-invasive Quick Measurement of Markedly Reduced Acetylcholine & DHEA and Increased ß-Amyloid (1-42), Asbestos (Chrysotile), Titanium Dioxide, Al, Hg & often Coexisting Virus Infections (CMV, HPV 16 and 18), Bacterial Infections etc. in the Brain and Corresponding Safe Individualized Effective Treatment.

A brief historical background on Autism & some of the important symptoms associated with Autism are summarized. Using strong Electro Magnetic Field Resonance Phenomenon between 2 identical molecules with identical weight (which received U.S. Patent) non-invasively & rapidly we can detect various molecules including neurotransmitters, bacteria, virus, fungus, metals & abnormal molecules. Simple non- invasive measurement of various molecules through pupils & head of diagnosed or suspected Autism patients indicated that in Autism patients following changes were often found: 1) Acetylcholine is markedly reduced; 2) Alzheimer's disease markers (i.e. ß-Amyloid (1-42), Tau Protein, Apolipoprotein (Apo E4)) are markedly increased; 3) Chrysotile Asbestos is increased; 4) Titanium Dioxide (TiO2) is moderately increased; 5) Al is moderately increased; 6) Hg is moderately increased; 7) Dopamine, Serotonin & GABA are significantly reduced (up to about 1/10 of normal); 8) Often viral infections (such as CMV, HHV-6, HPV-16, HPV-18, etc.), and Bacterial infections (such as Chlamydia trachomatis, Mycobacterium TB, Borrelia Burgdorferi, etc.) coexist. Research by others on Autism spectrum disorder (ASD) shows that it is a group of complex neurodevelopmental disorders, with about 70% of ASD patients also suffering from gastro-intestinal problems. While Alzheimer disease (AD) is characterized by formation of 1) Amyloid plaques, 2) Neurofibrillary tangles inside of neurons, and 3) Loss of connections between neurons. More than 90% of AD develops in people over the age of 65. These 3 characteristics often progressively worsen over time. Although Autism Spectrum Disorder and Alzheimer's disease are completely different diseases they have some similar biochemical changes. Eight examples of such measurement & analysis are shown for comparison. Most of Autism patients improved significantly by removing the source or preventing intake of Asbestos, TiO2, Al & Hg or enhancing urinary output of above abnormal substances & coexisting infections, if treatment is given early. When HPV-16 & HPV-18 coexist, at triangular central area of the top of head, in addition to inability to talk, severe neuromuscular problems of lower extremity were found to also exist. However, if treatment is given 3-4 years after onset of Autism symptoms, even when successful biochemical reduction of above abnormal substances occurs, clinical improvement is less significant, since permanent damage in brain tissue seems to already exist. Therefore, early diagnosis & early treatment is very important for both Autism & Alzheimer's disease. In addition the optimal doses of Vitamin D3 and Taurine may play an important role in the future treatment of Autism, Alzheimer's Disease and memory disturbances by significantly increasing Acetylcholine and DHEA levels, enhancing the excretion of toxic substances in the urine, as well as having an anticancer effect.

The aqueous extract of Ficus religiosa induces cell cycle arrest in human cervical cancer cell lines SiHa (HPV-16 Positive) and apoptosis in HeLa (HPV-18 positive).

Natural products are being extensively explored for their potential to prevent as well as treat cancer due to their ability to target multiple molecular pathways. Ficus religiosa has been shown to exert diverse biological activities including apoptosis in breast cancer cell lines. In the present study, we report the anti-neoplastic potential of aqueous extract of F. religiosa (FRaq) bark in human cervical cancer cell lines, SiHa and HeLa. FRaq altered the growth kinetics of SiHa (HPV-16 positive) and HeLa (HPV-18 positive) cells in a dose-dependent manner. It blocked the cell cycle progression at G1/S phase in SiHa that was characterized by an increase in the expression of p53, p21 and pRb proteins with a simultaneous decrease in the expression of phospho Rb (ppRb) protein. On the other hand, in HeLa, FRaq induced apoptosis through an increase in intracellular Ca(2+) leading to loss of mitochondrial membrane potential, release of cytochrome-c and increase in the expression of caspase-3. Moreover, FRaq reduced the migration as well as invasion capability of both the cervical cancer cell lines accompanied with downregulation of MMP-2 and Her-2 expression. Interestingly, FRaq reduced the expression of viral oncoproteins E6 and E7 in both the cervical cancer cell lines. All these data suggest that F. religiosa could be explored for its chemopreventive potential in cervical cancer.

A patient-centered approach to counseling patients with head and neck cancer undergoing human papillomavirus testing: a clinician's guide.

The International Agency for Research on Cancer and the National Cancer Institute have acknowledged human papillomavirus (HPV)-16 as an independent risk factor for oropharyngeal cancer (OPC). HPV-positive oropharyngeal cancer (HPVOPC) is a sexually transmitted entity that is on the rise; within the next 10 years, the annual number of HPV-associated OPC cases is projected to exceed the annual number of cervical cancer cases in the United States. Recognition of HPV status in OPC has broad implications beyond the traditional oncological concerns of timely diagnosis, accurate staging, and appropriate treatment of cancer patients. The National Comprehensive Cancer Network recommends testing the tumor site for HPV-status during OPC management; it is likely this will become a standard component of care for patients with high-probability tumors of the oropharynx. As the practice of HPV testing becomes more common, it behooves providers to be able to adequately address the concerns of patients with HPVOPC. Although there are currently few relevant studies focusing on this population, existing literature on HPV-infected women and patients with cervical cancer strongly supports the concept that patients with HPVOPC need education to optimally address concerns such as self-blame, guilt, intimacy, and interpersonal relationships. When HPV testing is done, it should be accompanied by evidence-driven and patient-centered counseling to best minimize negative psychosocial outcomes and ensure optimum health promotion. Based on the current state of the literature, this article is intended to be a reference for physicians to effectively manage psychosocial outcomes when diagnosing patients with HPV-associated OPC.

More than 97% of human papilloma virus type 16 (HPV-16) was found with chrysotile asbestos & relatively smooth round tumor outline, and less than 3% was found with HPV-18 and tremolite asbestos & irregular sawtooth-like zigzag outline in breast cancer tissues in over 500 mammograms of female patients: their implications in diagnosis, treatment, and prevention of breast cancer.

In the past, Human Papillomavirus Type 16 (HPV-16) was considered to be the main cause of cancer in the oropharynx and genital organs. Cervical cancer of the uterus is the most well-known cancer associated with HPV-16. Among the oncogenic HPVs, types 16 and 18 are most responsible for the majority of the HPV-caused cancers. Recently, using EMF Resonance Phenomenon between 2 identical substances, we non-invasively measured HPV-16 and HPV-18 among 25 physicians and 25 dentists and found that all 50 have HPV-16 in oral cavities and oropharynx but not HPV-18. However most dentists have a stronger infection than physicians. Among them were 2 female dentists with breast cancer containing HPV-16 and strong infections of HPV-16 in the oral cavities and oropharynx. When the author checked their breast cancer positive areas as well as the mammograms of cancer positive areas, Chrysotile Asbestos co-existed with an infection of HPV-16. We then examined over 500 published mammograms of women with malignant breast cancer published by other institutes, and we found HPV-16 in more than 97% and HPV-18 in less than 3% of the breast cancer mammograms examined. Less than 0.4% of cases were found as a variety of combination of HPV-16 & HPV-18. We also discovered that breast cancer with HPV-16 always co-exists with increased Chrysotile Asbestos deposits, and the outline of the breast cancer positive area is a relatively smooth and round or oval shape, and breast cancer with HPV-18 always co-exists with increased Tremolite Asbestos, where the tumor outline is an irregular saw-tooth like zigzag pattern. Based on these findings, better methods of diagnosis, treatment and prevention with a vaccine can be developed.

Local inflammation and human papillomavirus status of head and neck cancers.

OBJECTIVE: To determine whether periodontitis is associated with human papillomavirus (HPV) status of head and neck squamous cell carcinoma (HNSCC). DESIGN AND SETTING: Hospital-based case-control study in a comprehensive cancer center. PATIENTS: Evaluation included all patients diagnosed with incident primary squamous cell carcinoma of the oral cavity, oropharynx, and larynx between 1999 and 2007 for whom tissue samples and dental records were available (N = 124). Patients younger than 21 years and those with a history of cancer were excluded. Periodontitis history was assessed by alveolar bone loss in millimeters from panoramic radiographs by one examiner blinded to cancer status. MAIN OUTCOME MEASURE: The presence of HPV-16 DNA in paraffin-embedded tumor samples was identified by polymerase chain reaction. RESULTS: The prevalence of HPV-positive HNSCC was 50 of 124 patients (40.3%). A higher proportion of oropharyngeal cancers were HPV-positive (32 of 49 [65.3%]) compared with oral cavity (9 of 31 [29.0%]) and laryngeal (9 of 44 [20.5%]) cancers. Each millimeter of alveolar bone loss was associated with 2.6 times increased odds (odds ratio [OR], 2.61; 95% CI, 1.58-4.30) of HPV-positive tumor status after adjustment for age at diagnosis, sex, and smoking status. The strength of the association was greater among patients with oropharyngeal SCC (OR, 11.70; 95% CI, 2.09-65.53) compared with those with oral cavity SCC (OR, 2.32; 95% CI, 0.65-8.27) and laryngeal SCC (OR, 3.89; 95% CI, 0.95-15.99). CONCLUSIONS: A history of chronic inflammatory disease in the oral cavity may be associated with tumor HPV status in patients with HNSCC. This association seems to be stronger among patients with oropharyngeal cancer compared with those who have oral cavity or laryngeal SCC.

Progressive miRNA expression profiles in cervical carcinogenesis and identification of HPV-related target genes for miR-29.

miRNAs have the potential to act on diverse downstream genes, and miRNA signatures of HPV-infected tissues may provide insight into HPV-related carcinogenesis. We set out to profile miRNA expression in HPV-infected samples and relate this to histological and grade-specific alterations in the spectrum of cervical carcinogenesis in vivo. A total of 31 miRNAs showed significant and continuous expression along with the progression from normal cervical tissue to cancer, and six of them were validated in 133 samples. By bioinformatics analyses, we established a putative HPV-associated miRNA-mRNA regulatory network, showing that miR-29 is the most highly enriched. We also found that YY1 and CDK6 were both positively correlated with E6/E7 RNA expression and targeted by tumour-suppressive miR-29. Evidence of miR-29 involvement in HPV infection was further verified in patient samples and by various experimental approaches. Taken together, our results suggest that HPVs have oncogenic properties at least in part by reshaping the milieu of cellular miRNAs. miR-29 restrains cell cycle progression and induces apoptosis via YY1 and CDK6 promoting malignant transformation induced by HPV, although the abnormality of miR-29 in HPV-infected cells might be regulated in an indirect way.
