This study was designed to determine themost prevalent HPV genotypes in women with normal and abnormal cervical cytology in Iran. Materials and Methods:Samples from134 patients, including 127 who attended gynecology clinics and 7 with solid cervical tumors wereused. All 127 patients underwent routine Pap tests for cytological evaluation and at the same visit a sample ofcervical epithelial cells was obtained by scraping the cervix osteum. In each case HPV infection was primarily evaluatedby PCR using GP 5/6 primers and then subtyping was performed in proved infected samples with specific primersfor HPV 16, 18, 31, 33, 11 and 6. After cytological evaluation, 50 patients with abnormal Pap tests were categorizedas the abnormal group and the remaining 77 patients as the normal group. Results: In the normal group, HPVinfection was established in 10 cases (13% infection rate), while 30 HPV positive cases were discovered in the abnormalgroup (60% infected). The most prevalent genotypes among the infected samples were HPV 16 (76%), HPV18 (12.7%)and HPV11/6 (8.5%). Moreover, all 7 tumor samples were positive for HPV general primers of which, 5 sampleswere infected with HPV 16, two were co-infected with HPV16,18 and HPV16,31 genotypes and one was infected withHPV 18. Conclusions: Infection with HPV 16 was found to be significantly higher in abnormal group in comparisonwith normal group (42% vs. 11.6%, P value <0.005), likewise HPV18 genotypes were proved to be more prevalent inabnormal group (8% vs. 0%, P value <0.05). No significant relation between other HPV genotypes and pathologiccervical changes was obtained.

To investigatewhether high serum levels of carotenoids can reduce mortality rates, a population-based follow-up study was conductedamong Japanese inhabitants. Materials and Methods: Three thousand two hundred and fifty-four subjects (1,260males and 1,994 females) aged from 39 to 85 years who had attended health check-up programs from 1989 to 1995were recruited from the Japanese population. Serum levels of carotenoids, retinol and tocopherols were separatelydetermined by high-performance liquid chromatography. Hazard ratios for serum values of carotenoids, retinol andtocopherols were estimated by Cox’s proportional hazard model after adjusting for sex, age, and other confoundingfactors. Results: During the 11.7-year follow-up period, 140 deaths (86 males and 54 females) from cancer of all siteswere identified among the cohort subjects, including 41 from lung , 17 from stomach , 16 from colorectal and 12from liver cancer, as well as 89 deaths from cardiovascular disease, including 45 from heart disease and 37 fromstroke. High serum values of carotenoids including xanthophylls were apparently associated with low hazard ratiosfor mortality rates of cancer of all sites or of cardiovascular disease. High serum values of β-carotene, total carotene,provitamin A and total carotenoid for colorectal cancer or stroke also appeared to be related to low hazard ratios.Those of retinol and tocopherols were not associated with any reduction in risk of mortality from cancer orcardiovascular disease.

Data were derived from theNational Cancer Registry Program of India, other Indian registries, the International Agency for Research on Cancer,and the US/ NCI Surveillance, Epidemiology, and End Results (SEER) Program. Results: Average annual cancerincidence rates in India ranged from 5.0 to 9.1 per 100,000/year for prostate and 7.2 to 31.3 per 100,000/year forfemale breast. Comparative rates in the US for prostate cancer are 110.4 for Whites and 180.9 for Blacks; for femalebreast, the rates are 86.6 for Blacks and 96.4 for Whites. Notable differences were observed between rural and urbanareas in India, while such differences by rurality appear to be much smaller in the US. Overall, about 50-55% ofbreast cancer cases and about 85% of prostate cancers were detected at late (III and IV) stage; in contrast to the USwhere 15% of either cancer is diagnosed at late stage.

Inherently,the process of neoplastic conversion selects against apoptosis to initiate, promote, and perpetuate the malignantphenotype. Thus, targeting apoptosis pathways in pre-malignant cells, in which these pathways are still relativelyintact, may be an effective module of cancer prevention. Diallyl sulfide (DAS), a naturally occurring organosulfide,present in garlic, is reported to have pleiotropic biological effects. DAS is known to inhibit chemically inducedtumors in a number of in vivo and in vitro studies. The aberration of tumor suppressor gene, p53 and the rasoncogene have been linked to the induction of multiple signaling pathways and to the resistance offered by cancercells to the apoptosis. Therefore, the present study was carried out to investigate the role of DAS on modulation ofmultiple p53 and ras-induced signaling pathways in 7,12-dimethylbenathacene (DMBA) induced skin carcinogenesis.The results showed that DAS up regulates expression of tumor suppressor protein p53 (wt p53) and its downstreamtarget molecule p21/waf1. Proapoptotic protein, bax was upregulated by DAS supplementation. An opposite trendwas observed in DMBA induced antiapoptotic proteins expressions, survivin and bcl-2, which were significantlydownregulated by DAS supplementation. In the present study we also demonstrated that DAS supplementationsignificantly reduces the expression of ras oncoprotein and to modulate expression of its signaling molecules includingPI3K/Akt and MAPKs. Western blot analysis demonstrated that DAS significantly reduced the DMBA inducedprotein expressions of PI3K/Akt and p38MAPK. However, DAS supplementation did not alter the expression JNK1and ERK1/2. Thus, our results confirm that DAS can adopt a multi-prong strategy to target multiple signalingpathways leading to induction of apoptosis and inhibition of growth of DMBA induced skin tumors in Swiss albinomice.

Women testing positive were colposcoped by a medical officer at the samesitting. Based on the feedback from a few focus group discussions a structured questionnaire was designed to interviewthe women after screening. A total of 498 women were selected randomly from the screened women for interview bya social worker. Besides enquiring about any discomfort they faced during or within seven days after screening, thewomen were also asked to indicate their level of satisfaction with the service.

Adolescent behavior leading to high sexual risk includedbeing very close to friends, having a wide social circle, going out for enjoyment at night time, returning home late atnight, drinking alcohol, smoking, paying less attention to learning, not listening to parents, and not following theiradvice. Adolescent sexual behavior was found to comprise: 1) sexual activities themselves; 2) non-disclosure ofhaving sex; and 3) protective behavior. Sexual activities were ranked from low risk to high risk of sexual health.Low risk included having a steady boy/girlfriend, hugging, and kissing. High risk sexual behavior featured unprotectedsex, abuse or rape, and abortion. Important influences were: eagerness to learn and try to have sex, mens’ sexualdesire, peer group value of having sex, and material value.

Patients andMethods: We retrospectively studied all histopathologically proven cases of HL, who presented between Dec 1995 toJune 2003 at Shaukat Khanum Memorial Cancer Hospital and Research Hospital (SKMCH & RC). All the relevantinformation was obtained through the hospital based cancer registry and medical records of the selected patients.Results: Six hundred and fifty eight histopathologically confirmed cases of HL were identified. There were 505 malesand 153 females, with a male to female ratio of 3.3: 1. Patients ranged in age from 1 year - 84 years. The mean age atpresentation was 23.8 years. Three hundred and twenty cases (48.6%) belonged to age group ≤ 18 years and 338cases (51.4%) were > 18 years of age. Histopathologically, mixed cellularity (MC) constituted 63.8% of cases, followedby nodular sclerosis (NS) 19.9%, lymphocyte predominant (LP) 7.3% and lymphocyte depleted (LD) 1.2%. Earlystage (stage I and II) disease was present in 43.9% of patients at presentation, while 56.1% patients presented withadvanced stage (stage III and IV).

In fact, the increase in the rate of breastcancer mortality in Korea over the past 10 years has been higher than anywhere else in the world, and it is particularlynoteworthy that more than half of the incident cases occur among those younger than 50 years of age. The rapidwesternization of dietary habits and changes in reproductive behavior of Korean women presumably played a centralrole in this extraordinary increase in breast cancer occurrence. A large-scale multi-center case-control analysisshowed that an older age, a family history of breast cancer, early menarche, late menopause, late full-term pregnancy,never-having had a breast-fed child, and postmenopausal obesity are breast cancer risk factors in Korea.Environmental and genetic factors are known to play interactive roles in human carcinogenesis and recent studieshave shown that genetic polymorphisms may predispose individuals to breast cancer via gene-to-environment orgene-to-gene interactions. Thus research into genetic variation in xenobiotic metabolism, estrogen metabolism, DNArepair, cytokine metabolism, or cell cycle control may give insights into both the etiology and prevention of breastcancer. Epidemiologic evidence obtained from migrant and lifestyle change studies and investigations of main riskfactors strongly suggests that breast cancer will further increase in Korea. Future predictions point to a 2- to 3-foldincrease in incidence by 2020.

HPV high risk strains play atleast the major if not an absolutely necessary role in the etiology. The concept of cervical intraepithelial neoplasia(CIN) was introduced in 1968 as an equivalent to the term dysplasia, which means abnormal maturation. Cervicalcancer progresses slowly from preinvasive CIN to invasive cancer and therefore screening for dysplasia is an importantpublic health effort worldwide, given the accessibility of the primary organ site, the acceptability of current screeningmethods, and the long preinvasive period in which to detect disease and successfully intervene. It is widely acceptedthat detection and treatment of HPV-related dysplastic epithelial change in the form of CIN-2 and CIN-3 canprevent the development of invasive cervical cancer in individual patients. The mainstay of screening programs hasbeen the Pap smear, introduced originally by George Papanicolaou in 1941. However, considerable numbers of falsenegativePap smears may occur with the traditional Pap technique, mostly due to sampling error. More recently, theuse of liquid-based technologies such as ThinPrep and AutoCyte Prep have gained popularity, in part because ofevidence suggesting reduction in the incidence of inadequate smears. It is also hoped that the ability to identifypatients with oncogenic HPV types will lead to improved detection in women more likely to have squamousintraepithelial lesions. Hybrid Capture 2 is the latest refinement of HPV tests and has been described as havingenhanced sensitivity. HPV DNA testing can be used as an adjunct to cytology in routine cervical disease screeningprograms. Establishment of the link between HPV and cervical cancer has further provided the impetus for researchinto prophylactic vaccination against the most common HPV types associated with the disease, HPV 16 and 18.Initial studies have provided evidence that L1 virus-like particle vaccines against HPV types (as monovalent, bivalent,or quadrivalent vaccines) prevent at least 90% of incident and persistent infections and their associated precursorsof cervical cancer. This vaccine has sustained long-term vaccine efficacy against incident and persistent infectionsand in the long term should provide an answer to the cervical cancer problem. For the vast majority of women whohave already been infected, however, continued screening and resection need to be emphasized.}, keywords = {cervical cancer,Screening,Prevention,Vaccination}, url = {https://journal.waocp.org/article_24551.html}, eprint = {https://journal.waocp.org/article_24551_726eff3f3bb523ed07b630f874941135.pdf} }
