Background and purpose: Human papillomavirus infection is the most important risk factor and necessary cause of cervical cancer. The aim of this study was to determine the genotypes of HPV DNA in cervical carcinoma samples from Shohada and Imam Hossien Hospitals in Tehran, between 1999 and 2008. Materials and methods: After the paraffin alleviation process from the sections needed for HPV typi...
Human papillomavirus (HPV) DNA has been identified in esophageal carcinomas. However, the incidence of HPV varies significantly in different geographical locations. In this study, neoplasms from Turkmen Sahra, a region in Golestan province in northeast part of Iran, with a high incidence of squamous cell carcinoma were analyzed for the presence of HPV DNA. Turkmen Sahra is located in the cancer...
results human papillomavirus was found in 62.1% of the samples obtained from the patients. among the hr and lr types, hpv-6 was the major genotype 64.8%. type 16 and 18 were the most frequent hr-hpv types (presented in 26% of the patient), followed by type 50s (24.7%), 45, 30s, and 11 (1.8% from each). multiple hpv infections were presented in 40.7% of the positive genotyping specimens. backgro...
Background: Epidemiological studies are shown robust association between human papillomavirus (HPV) and cervical cancer. From 1990 HPV was known as a necessary but insufficient cause of cervical invasive cancer. The purpose of this study was to evaluate the cost effectiveness of HPV test in cervical cancer screening. Materials and Methods: This is a systematic review article; the newest scienti...
Background and Objectives: Breast cancer is the most common malignancy in women throughout the world. There are controversial reports on the role of human papillomavirus (HPV) infection in breast carcinogenesis. The aim of this study was to assess the presence of HPV-DNA in invasive breast carcinoma to determine the association between HPV infection and breast carcinoma. Methods: The study inc...
conclusions the high prevalence of hpv in abnormal cytology underlines to the fact that the presence of hpv is a critical factor in the development of cervical cancer. the use of hpv dna techniques could actually become an effective and fast means of ascertaining the presence of hpv in abnormal cytology. results result showed a 100% presence of high risk hpv in all the samples with abnormal cyt...
زمینه و هدف: ویروس پاپیلوم انسانی (HPV) یکی از مهمترین مشکلات بهداشت عمومی و عامل اصلی سرطان دهانۀ رحم است. عفونت HPV در کشورهای در حال توسعه با منابع مالی کم، شیوع زیادی دارد. این مطالعه با هدف تعیین فراوانی نسبی ژنوتیپهای HPV و خصوصیات مرتبط با آن در زنان مراجعه کننده به یکی از بیمارستانهای عمومی شهر تبریز انجام شده است. مواد و روشکار: این مطالعۀ مقطعی روی ۴۰۰ زن با نمونۀ پاپ اسمیر، مرا...
ویروس پاپیلومای انسانی (hpv)، یک عامل بیماری زای مهم است که می تواند باعث ایجاد مشکلاتی در سلامتی گردد. hpv به خانواده پاپیلوماویریده تعلق دارد. این ویروس دارای ژنوم dna دو رشته ای می باشد که این ژنوم توسط پروتئین های کپسیدی حفاظت می شود. تا به حال، بیش از 200 تایپ hpv مختلف شناسایی شده است. hpvها به دو گروه جداگانه ی پرخطر و کم خطر دسته بندی می شوند. تایپ های کم خطر مانند hpv6 و hpv11 باعث ایج...
Human papillomavirus (HPV) is one of the most common causes of sexually transmitted diseases worldwide and is the etiological agent of cervical and other anogenital malignancies. Since HPVs have been shown to possess oncogenic potential, an association between HPV infection and prostatic cancer (PCa) has been suggested. There are conflicting reports on the impact of HPV infection on the deve...
Purpose. Evaluate if human papillomavirus (HPV) infection in lung cancer patients might be helping development by altering p16, p21, and PCNA, key genes involved cell proliferation tumor development. Methods. 63 fresh-frozen (FF) formalin-fixed paraffin-embedded (FFPE) samples from were used to detect HPV PCR, followed genotype through sequencing. The host gene expressions of PCNA quantified qP...
