Rare cases of metastatic squamous cell carcinoma with chondroid differentiation from esophageal primary have been reported but none from the uterine cervix. Given the rarity of this phenomenon and potential diagnostic pitfall, we present this unusual case. The patient is a 25-year-old woman who presented with shortness of breath. Computerized tomography (CT) showed several lung and pleural-based nodules. CT-guided core biopsy with touch preparations were performed on the pleural-based nodule. The touch preparations showed large, spindle-to-oval shaped cells with pleomorphic nuclei embedded in metachromatic chondroid stroma...

Dysregulated expression of oncogenic types of E6 and E7 is necessary for human papillomavirus (HPV)-driven carcinogenesis. An HPV E6/E7 mRNA in situ hybridization (ISH) assay covering 18 common high-risk types ("HR-RISH," aka HR-HPV RNA18 ISH) has not been extensively studied in the anogenital tract or validated on automated technology. We herein compare HR-RISH to DNA polymerase chain reaction (PCR), p16 immunohistochemistry, and a previously available HPV DNA ISH assay in HPV-related anogenital and head and neck (H&N) neoplasia...

No definitive cure is known for recurrent, persistent or metastatic cervical carcinoma. Chemotherapy remains the standard of care, although available options are scarce and do not provide satisfactory results. Immune checkpoint inhibitors have shown a strong and prolonged response in several types of cancer, although only in a subset of patients. Defining the profile of the patients likely to benefit from such treatment is a subject of active research. Here, we present a case of a heavily pretreated patient with recurrent advanced squamous cell carcinoma of the cervix who had exhausted all available treatment options and showed a striking response to the immune checkpoint inhibitor pembrolizumab...

Collision tumours are defined by co-existence of two tumours in the same or adjacent organs which are topographically and histologically distinct with minimal or no histological admixture. Collision tumours have been described in many organs notably thyroid, brain, adrenal gland, stomach and rarely uterus. Most of the collision tumours reported in uterus have two components; an adenocarcinoma and a sarcoma. We report a case of a 60-year-old lady who presented with complaints of post-menopausal bleeding. A cervical biopsy was performed which showed a non-keratinizing squamous cell carcinoma of cervix...

Most of the drugs used in chemotherapy should be activated by a transformation catalyzed by cytochrome P450 (CYP) enzymes. In this work, bacteriophage P22 virus-like particles (VLPs) containing CYP activity, immunologically inert and functionalized in order to be recognized by human cervix carcinoma cells and human breast adenocarcinoma cells were designed. The CYP was encapsulated inside the virus capsid obtained from the bacteriophage P22. CYP and coat protein were both heterologously expressed in E. coli...

5-(2-(4-Methoxyphenyl)ethyl)-2-amino-3-methylcarboxylate thiophene (TR560) is the prototype drug of a recently discovered novel class of tumor-selective compounds that preferentially inhibit the proliferation of specific tumor cell types (e.g. leukemia/lymphoma). Here, we further increased tumor selectivity by simplification of the molecule through replacing the 4-methoxyphenyl moiety by an alkyl chain. Several 2-amino-3-methylcarboxylate thiophene derivatives containing at C-5 an alkyl group consisting of at least 6 (hexyl) to 9 (nonyl) carbon units showed pronounced anti-proliferative activity in the mid-nanomolar range with 500- to 1000-fold tumor cell selectivity...

Although Human Papillomavirus (HPV) exerts a vital influence on cervical carcinogenesis, other factors influence the development of a squamous intraepithelial lesion (SIL) that may or not progress to cervical cancer. Among several cytokines, Interleukin 10 (IL-10) stands out as an important anti-inflammatory factor, leading to immune system evasion through an immunosuppressive state. In the cervical microenvironment, during different stages of HPV infection, IL-10 production can be induced and maintained by different cell sources, including infected keratinocytes, some subsets of dendritic cells (DC), tumor associated macrophages (TAM), T regulatory cells (Treg) and tumor cells...

Poor water solubility and adverse side effects pose a challenge for clinical application of paclitaxel (PTX). In this work, a series of PTX dimers are synthesized by coupling two PTX molecules with dicarboxylic acids. As-synthesized PTX dimers form stable nanoparticles in aqueous solution without using any surfactants or adjuvants, and the solubility of PTX in water increases by 2500-fold compared to that of free PTX. These nanoparticles with high content of PTX are internalized by cancer cells and exhibit comparable cytotoxicity with Taxol...

The aim of this study was to explore the correlation of ezrin and galectin-3 expressions with prognosis in cervical cancer. The immunohistochemical method was applied to detect ezrin and galectin-3 expressions in normal cervix tissues (n=30), cervicitis tissues (n=28), cervical intraepithelial neoplasia (CIN) tissues (classified as I-III, n=89), and cervical carcinoma tissues (n=84). Follow-up was conducted for 5 to 78 months to analyze the correlation of protein expressions with prognosis. Ezrin and galectin-3 expressions in cervical cancer were significantly higher than in normal cervix, cervicitis and CIN (all P<0...

Introduction. Infections caused by Pasteurella species are commonly associated with contact with dogs and cats, typically involving bites and scratches, but casual contact with household pets can also be a risk factor. Urinary tract infection (UTI) caused by Pasteurella species is rare and a significant majority of cases have some known risk factor associated with an underlying chronic illness or structural and/or functional urological abnormality. Case presentation. Here, we present a case of a UTI due to Pasteurella multocida in a patient with squamous cell carcinoma of the cervix who also had a household cat...

BACKGROUND: Cervical cancer progresses through different stages: a long stage of precancerous lesions, then high-grade squamous intraepithelial lesion (HSIL) stage in which precancerous lesions transform into invasive cervical carcinoma, and finally invasive squamous cell carcinomas (SCC) which is difficult to be treated and can be deadly. METHODS AND RESULTS: To identify critical genes for the development and progression of cervical cancer development, we analyzed an online database comprised of normal squamous cervical epithelia samples, HSIL samples and SCC of cervix...

OBJECTIVES: Human Epididymal Secretory Protein 4 was firstly described as an epididymis-specific protein but more recently it has been demonstrated to be a putative serum tumor marker for different malignancies, especially ovarian epithelial cancers. The aim of this study is to investigate the association between tissue Human Epididymal Secretory Protein 4 expression and the clinicopathological features of uterine cervical tumors. MATERIAL AND METHODS: This retrospective study was designed to evaluate the differences of tissue expressions of Human Epididymal Secretory Protein 4 protein in a spectrum of cervical neoplasms...

REVIEW
Sixto M Leal, Margaret L Gulley
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...

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...

Squamous cell carcinoma (SCC) of the uterine cervix occasionally demonstrates a deceptive growth pattern that mimics endocervical crypt involvement by cervical intraepithelial neoplasia, grade 3 (CIN 3). Such CIN 3-like SCCs may be misinterpreted as noninvasive or minimally invasive leading to delays in diagnosis. Little is known of the factors that influence the growth patterns of cervical SCC but we suggested recently that CIN 3-like tumors might demonstrate "collective cellular invasion," which is characterized by a retained epithelial phenotype...

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...
