Human papillomavirus (HPV) is an infection that can be sexually transmitted and result in health consequences. Persistent high-risk HPV infection can lead to various cancers and is the essential cause of cervical cancer. HPV vaccine can prevent the HPV infection and thus the incidence of cervical cancer. In this review we introduced the prevalence of HPV infection and vaccination, and the prevention and early detection of cervical cancer. We also introduced the present knowledge and awareness of HPV infection and HPV vaccine in Chinese...

Intratumor heterogeneity is a key factor contributing to therapeutic failure and, hence, cancer lethality. Heterogeneous tumors show partial therapy responses, allowing for the emergence of drug-resistant clones that often express high levels of the receptor tyrosine kinase AXL. In melanoma, AXL-high cells are resistant to MAPK pathway inhibitors, whereas AXL-low cells are sensitive to these inhibitors, rationalizing a differential therapeutic approach. We developed an antibody-drug conjugate, AXL-107-MMAE, comprising a human AXL antibody linked to the microtubule-disrupting agent monomethyl auristatin E...

Background: Chlamydia trachomatis (CT), the most common bacterial sexually transmitted infection (STI), leads to pelvic inflammatory disease, infertility and chronic pelvic pain in women as well as an increased risk of vertical transmission, conjunctivitis and pneumonitis in infants. It may also be a co-factor along with human papillomavirus (HPV) in cervical cancer progression. We aimed to determine the prevalence of CT genotypes in genital specimens of women from South Khorasan, Iran and to test the association between CT and cytology statistics...

Background: MicroRNAs (miRNAs) are non-coding small RNAs that function as negative regulators of gene expression and are involved in tumour biology. The eIF4E-binding proteins (eIF4EBPs) play essential roles in preventing translation initiation and inhibiting protein synthesis at a global or message-specific level in a variety of tumours. Methods: According to comparative miRNA profiles of clinical cervical cancer and non-cancerous cervical tissue specimens, several miRNAs were aberrantly expressed in the cervical cancer samples...

PURPOSE: MicroRNAs (miRs) have been implicated in many aspects of tumor cell development and survival, including sensitivity to radiotherapy. In particular, miR-19a regulates the proliferation of cervical cancer cells, but its role in radiosensitivity is not known. Here, we describe the consequence of silencing miR-19a using antisense oligonucleotides (ASO) on the radiosensitivity of human cervical cancer SiHa cells. METHODS: Following transfection with miR-19a-ASO or control-ASO, SiHa cells were exposed to X-rays to determine their proliferation...

INTRODUCTION: Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. PRESENTATION OF CASE: A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (<0,1 uUI/mL), thyroxine 1,44 ng/dL (normal range 0,70-1,48) and triiodothyronine 4,33 pg/mL (normal range 1,71-3,71)...

Isoprenylcysteine carboxylmethyltransferase (Icmt) catalyzes the last step of post-translational protein prenylation, which is essential for the stability and proper functions of many oncogenic proteins, such as Ras. Despite extensive studies on the roles of Icmt in tumor transformation and progression, little is known on the involvement ofIcmt in the development of tumor resistance to chemotherapy. Here we show the upregulation of Icmt as a persistent response to chemotherapy in cervical cancer cells. In-depth functional analysis demonstrated that Icmt inhibition significantly inhibited growth, induced apoptosis and augmented the inhibitory effects of chemotherapy drugs in cervical cancer in cell culture system and xenograft mouse model...

Sulforaphene (SFE), a natural isothiocyanate from cruciferous vegetables has shown a potential anticancer effect against cervical and lung cancer. Palliative treatments like photodynamic therapy (PDT) are being implemented for a long time however, the results are still not promising in case of aggressive cancers like anaplastic thyroid cancer. The objective of this work is to establish an alternative method with the combination of photofrin-PDT and sulforaphene, a natural isothiocyanate from cruciferous vegetables, against human anaplastic thyroid cancer to enhance the efficacy of PDT...

PURPOSE: To study the dosimetric impact of deformable image registration-based contour propagation on MRI-based cervical cancer brachytherapy planning. METHODS AND MATERIALS: High-risk clinical target volume (HRCTV) and organ-at-risk (OAR) contours were delineated on MR images of 10 patients who underwent ring and tandem brachytherapy. A second set of contours were propagated using a commercially available deformable registration algorithm. "Manual-contour" and "propagated-contour" plans were optimized to achieve a maximum dose to the most minimally exposed 90% of the volume (D90) (%) of 6 Gy/fraction, respecting minimum dose to the most exposed 2cc of the volume (D2cc) OAR constraints of 5...

Human papilloma virus (HPV) is a known cause of cervical cancer, squamous cell carcinoma and laryngeal cancer. Although treatments exist for HPV-associated malignancies, patients unresponsive to these therapies have a poor prognosis. Recent findings from vaccine studies suggest that T-cell immunity is essential for disease control. Because Epstein-Barr Virus (EBV)-specific T cells have been highly successful in treating or preventing EBV-associated tumors, we hypothesized that the development of a manufacturing platform for HPV-specific T cells from healthy donors could be used in a third-party setting to treat patients with high-risk/relapsed HPV-associated cancers...
