Background and Aims: The association between inflammatory bowel disease (IBD) and cancer remains poorly defined in Asian populations. Therefore, we conducted a nationwide population-based study to determine the cancer risk in Korean patients with IBD. Methods: Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD (5,595 Crohn's disease [CD] and 10,049 ulcerative colitis [UC]) from 2011 to 2014. Standardized incidence ratios (SIRs) of overall and site-specific cancers in IBD patients in comparison with the general population were calculated...

Laboratory tests have a key role in preventing human papillomavirus (HPV)-driven carcinomas and in guiding therapeutic interventions. An understanding of the virology, immunology, and carcinogenesis of HPV is essential for choosing appropriate diagnostic test modalities and developing new and even more effective cancer prevention strategies. HPV infects basal epithelial cells on multiple surfaces and induces carcinoma primarily in the cervix and the oropharynx. HPV types are stratified as high risk or low risk based on their carcinogenic potential, driven largely by viral interference with cell cycle regulation and the DNA damage response to promote continuous cell division while thwarting apoptosis, which enables mutation accumulation...

BACKGROUND: Investigation of brain cancer can detect the abnormal growth of tissue in the brain using computed tomography (CT) scans and magnetic resonance (MR) images of patients. The proposed method classifies brain cancer on shape-based feature extraction as either benign or malignant. The authors used input variables such as shape distance (SD) and shape similarity measure (SSM) in fuzzy tools, and used fuzzy rules to evaluate the risk status as an output variable. We presented a classifier neural network system (NNS), namely Levenberg-Marquardt (LM), which is a feed-forward back-propagation learning algorithm used to train the NN for the status of brain cancer, if any, and which achieved satisfactory performance with 100% accuracy...

Cervical cancer accounts for the second most frequent cancer and also third leading cause of cancer mortality (15%) among women worldwide. The major problems of chemotherapeutic treatment in cervical cancer are non-specific cytotoxicity and drug resistance. Plant-derived products, known as natural therapies, have been used for thousands of years in cancer treatment with a very low number of side effects. Allium atroviolaceum is a species in the genus Allium and Liliaceae family, which could prove to have beneficial effects on cancer treatment, although there is a lack of corresponding attention...

PURPOSE: Apparent diffusion coefficient (ADC) histogram analysis has been used to some extent in cervical cancer (CC) to distinguish between low-grade and high-grade tumors. Although this differentiation is undoubtedly helpful, it would be even more crucial in the presurgical setting to determine whether a tumor already gained the potential to metastasize via the lymphatic system. So far, no studies investigated the potential of 3T ADC histogram analysis in CC to differentiate between nodal-positive and nodal-negative entities...

BACKGROUND: Human papillomavirus (HPV) is the carcinogen of almost all invasive cervical cancer and a major cause of oral and other anogenital malignancies. HPV genotyping by dideoxy (Sanger) sequencing is currently the reference method of choice for clinical diagnostics. However, for samples with multiple HPV infections, genotype identification is singular and occasionally imprecise or indeterminable due to overlapping chromatograms. Our aim was to explore and compare HPV metagenomes in abnormal cervical cytology by deep sequencing for correlation with disease states...

There is plenty of substantial evidence to support anti-tumor activity of viruses. Adeno-associated virus (AAV) may interact with human papillomavirus (HPV) to modify the risk of cervical neoplasia. The seroprevalence of AAV among women with cervical cancer has been reported to be lower than healthy ones. In spite of this finding, detection of AAV DNA in cervical biopsies does not entirely support the inverse association between AAV seropositivity and cervical cancer. This association is still controversial and requires more thorough evaluation in different countries...

The objective of this paper was to define the effect of education on the early diagnosis of breast and cervix cancer on the women's attitudes and behaviors regarding participating in Cancer Early Diagnosis, Screening and Training Centers-CEDSTC screening programs. This semi-experimental study was completed with 342 women. The data were collected with forms "Champion's Health Belief Model Scale Breast Cancer-HBMSBC" and "Health Belief Model Scale for Cervical Cancer and the Pap Smear Test-HBMSCCPST." When the women's health beliefs before and after 6 months of the education about the early diagnosis of breast and cervical cancers are considered, it is seen that the HBMSBC subscales health motivation, breast self-examination (BSE), and evasion to mammography (MMG) decreased and BSE self-efficacy and MMG benefit attitudes increased and HBMSCCPST subscales pap smear benefit attitudes increased and evasion to pap smear attitude decreased (p < 0...

REVIEW

Repeated parity and usage of oral contraceptives have demonstrated an increased risk of cervical cancer (CC) in HPV-infected women. These lifestyle observations raise the likelihood that oestrogens and HPV infection might act synergistically to affect cancers of the cervix. In vivo studies have indicated the requirement of oestrogens and ERα in the development of atypical squamous metaplasia followed by cervical intraepithelial neoplasia (CIN) I, II and III. CIN II and III are precancerous cervical lesions that can progress over time to CC as an invasive carcinoma...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

Clear cell adenocarcinoma of the cervix (CCAC) is a rare type of gynecological cancer. The risk factors and pathogenesis have yet to be clearly determined. This is a case report of a 19-year-old woman, who was never exposed to DES from her mother, who had gone for an examination for vaginal bleeding. A polypoid mass measured at 3 cm presenting in her cervix was discovered. Histological diagnosis following cervical biopsy proved the tumor to be a clear cell carcinoma. The patient was then referred to our hospital...
