Abstract
BACKGROUND Several pathological parameters, including tumor size, depth of stromal invasion, lympho-vascular space invasion and lymph node status, have been proposed as prognostic predictors in cervical cancer. However, given the high mortality and recurrence rate of cervical cancer, novel parameters that are able to provide additional prognostic information are needed in order to allow a better prognostic stratification of cervical cancer patients. METHODS A search was conducted on PubMed to identify relevant literature data regarding prognostic factors in cervical cancer. The key words "cervical cancer", "prognostic factors", "pathology", and "outcome" were used. RESULTS The novel pathological grading system based on tumor budding and cell nest size appeared the most relevant prognostic factor in primary neoplasms. Moreover, other potentially useful prognostic factors were tumor size, depth of stromal invasion, lympho-vascular space invasion, perineural invasion, tumor-free distance and tumor-infiltrating lymphocytes. Prognostic factors related to advanced-stage cervical cancer, including lymph-nodes status, endometrial and cervical involvement as well as distant metastases, were also taken into consideration. CONCLUSIONS According to our findings, tumor budding and cell nest size grading system, depth of stromal invasion, lympho-vascular space invasion, perineural invasion, tumor-free distance and tumor-infiltrating lymphocytes appeared the most relevant factors included in the pathology report.

End-to-end computational approach to the design of RNA biosensors for detecting miRNA biomarkers of cervical cancer. Synth Syst Biotechnol 2022; 7:802-814. [PMID: 35475253 PMCID: PMC9014444 DOI: 10.1016/j.synbio.2022.03.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 02/25/2022] [Accepted: 03/23/2022] [Indexed: 12/18/2022] Open
Abstract
Cervical cancer is a global public health subject as it affects women in the reproductive ages, and accounts for the second largest burden among cancer patients worldwide with an unforgiving 50% mortality rate. Relatively scant awareness and limited access to effective diagnosis have led to this enormous disease burden, calling for point-of-care, minimally invasive diagnosis methods. Here, an end-to-end quantitative unified pipeline for diagnosis has been developed, beginning with identification of optimal biomarkers, concurrent design of toehold switch sensors, and finally simulation of the designed diagnostic circuits to assess performance. Using miRNA expression data in the public domain, we identified miR-21–5p and miR-20a-5p as blood-based miRNA biomarkers specific to early-stage cervical cancer employing a multi-tier algorithmic screening. Synthetic riboregulators called toehold switches specific to the biomarker panel were then designed. To predict the dynamic range of toehold switches for use in genetic circuits as biosensors, we used a generic grammar of these switches, and built a neural network model of dynamic range using thermodynamic features derived from mRNA secondary structure and interaction. Second-generation toehold switches were used to overcome the design challenges associated with miRNA biomarkers. The resultant model yielded an adj. R2 ∼0.71, outperforming earlier models of toehold-switch dynamic range. Reaction kinetics modelling was performed to predict the sensitivity of the second-generation toehold switches to the miRNA biomarkers. Simulations showed a linear response between 10 nM and 100 nM before saturation. Our study demonstrates an end-to-end computational workflow for the efficient design of genetic circuits geared towards the effective detection of unique genomic/nucleic-acid signatures. The approach has the potential to replace iterative experimental trial and error, and focus time, money, and efforts. All software including the toehold grammar parser, neural network model and reaction kinetics simulation are available as open-source software (https://github.com/SASTRA-iGEM2019) under GNU GPLv3 licence.

Abstract
Most cervical carcinomas and their related lesions are attributed to an infection by human papillomavirus (HPV). The infection usually starts in the basal cells at the squamocolumnar junction. It causes cell proliferation and maturation abnormalities along with nuclear abnormalities resulting in low-grade squamous intraepithelial lesions. An overwhelming majority of these lesions spontaneously disappear, and the infection is cleared. In a small subset of high-risk HPV infection cases, the lesions may persist and progress to high-grade squamous intraepithelial lesions. These are associated with the incorporation of the viral genome into the human genome. Some of the high-grade squamous intraepithelial lesions, over several years, progress to invasive carcinoma. Carcinomas of the cervix are usually squamous cell carcinomas (SCCs), but 20% to 25% of the cases may manifest as adenocarcinomas. Similar to SCC, adenocarcinomas may initially manifest as adenocarcinomas in situ and may progress to invasive carcinomas after a variable period of time. In the recently published World Health Organization classification of female genital tumors, SCCs, and adenocarcinomas of the cervix are divided into HPV-associated and HPV-independent tumors. This review draws on the latest terminology and the several morphologic subtypes recognized for each category.

Abstract
There is a lack of consensus regarding the prognostic value of grading endocervical adenocarcinomas and currently, no universally applied, validated system for grading exists. Several grading schemes have been proposed, most incorporating an evaluation of tumor architecture and nuclear morphology and these are often based on the International Federation of Gynecology and Obstetrics (FIGO) system for endometrial endometrioid carcinoma, although some schemes modify the proportion of solid tumor required to separate grades 1 and 2 from 5% to 10%. In the absence of a validated system, we endorse this approach for most human papillomavirus-associated endocervical adenocarcinomas and, based on the available evidence, recommend that tumors with ≤10% solid growth be designated grade 1, 11% to 50% solid growth grade 2 and >50% solid growth grade 3. Tumors should be upgraded in the presence of marked nuclear atypia involving the majority (>50%) of the tumor. Grading is not recommended for human papillomavirus-independent adenocarcinomas, since no validated system has been suggested and most of these neoplasms exhibit intrinsically aggressive behavior regardless of their morphologic appearance. Importantly, grading should not be performed for gastric-type adenocarcinomas, particularly as these tumors may appear deceptively "low-grade" yet still exhibit aggressive behavior. Recently devised, validated and reproducible etiology and pattern-based tumor classification systems for endocervical adenocarcinomas appear to offer more effective risk stratification than tumor grading and, in the future, these systems may render the provision of a tumor grade redundant.

Abstract
Cervical carcinoma is the fourth most frequent cancer among women worldwide while it is common in rural India. The irony of the situation is that it continues to present in a locally advanced stage with bulky disease posing a significant challenge to the current treatment modalities despite various screening programs. Concurrent chemoradiotherapy is the mainstay of treatment for locally advanced carcinoma cervix. However, the appropriate dosing schedules, along with the salutation of the chemotherapeutic agent, remain a matter of debate to date. The use of chemotherapy in the neoadjuvant and adjuvant setting promises to improve progression-free survival and overall survival. The article aims to review various chemotherapy and their regimens in the treatment of carcinoma of the cervix.

Abstract
Cervical cancer (CC) is usually initiated by infection with high‐risk types of human papillomavirus (HPV). The HPV E6 and E7 proteins target p53 and RB, respectively, but other cellular targets likely exist. We generated uterus‐specific MOB1A/B double KO (uMob1DKO) mice, which immediately developed cervical squamous cell carcinoma in situ. Mutant cervical epithelial cells showed YAP1‐dependent hyperproliferation, altered self‐renewal, impaired contact inhibition, and chromosomal instability. p53 activation was increased in uMob1DKO cells, and additional p53 loss in uMob1DKO mice accelerated tumor invasion. In human CC, strong YAP1 activation was observed from the precancerous stage. Human cells overexpressing HPV16 E6/E7 showed inactivation of not only p53 and RB but also PTPN14, boosting YAP1 activation. Estrogen, cigarette smoke condensate, and PI3K hyperactivation all increased YAP1 activity in human cervical epithelial cells, and PTPN14 depletion along with PI3K activation or estrogen treatment further enhanced YAP1. Thus, immediate CC onset may initiate when YAP1 activity exceeds an oncogenic threshold, making Hippo‐YAP1 signaling a major CC driver.

Abstract
Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are two homologous transcriptional coactivators and the final effectors of the Hippo signaling transduction pathway. The transcriptional activity of YAP/TAZ is dependent on their recruitment to the nucleus, which promotes binding to the transcription factor of TEA domain family members 1–4 (TEAD1-4). In Hippo-signaling pathway, YAP/TAZ is inactivated and its translocation to the nucleus is blocked via a core kinase cascade stimulated by a variety of upstream signals, such as G-protein-coupled receptor signaling, mechanical pressure, and adherens junction signaling. This pathway plays a very important role in regulating organ size, tissue homeostasis, and tumor development. In recent years, many studies have reported upregulation or nuclear localization of YAP/TAZ in a number of human malignancies, such as breast cancer, melanoma, lung cancer, especially squamous cell carcinoma in different organs. A large number of experiments demonstrate that YAP/TAZ activation promotes cancer formation, progression, and metastasis. Therefore, in this review, we summarize the evidence of regulation and function of YAP/TAZ and discuss its role in squamous cell carcinoma. Collectively, this summary strongly suggests that targeting aberrant YAP/TAZ activation is a promising strategy for the suppression of squamous cell carcinoma.

Abstract
Cervical cancer is a type of slow-growing cancer associated with high mortality rates. Early detection can enable lifesaving early intervention. Current cervical premalignant lesion detection methods suffer from both high miss rates and excessive referrals for unnecessary biopsies. Herein, coherent light backscatter and modifications in reflected white-light spectra were measured to specifically discriminate between cervical tumors and normal squamous epithelial tissues resected from a mouse xenograft model. The combined measurements resulted in 92% sensitivity and 93% specificity in discrimination between the two tissues. These methods can be used to develop a noninvasive portable optical probe for sensitive and objective detection of precancer and cancer epithelial lesions in the cervix and other accessible epithelial tissues.

Abstract
PURPOSE This study sought to evaluate the safety of conservative treatment in the management of patients with microinvasive cervical adenocarcinoma. METHODS The PubMed, PMC, EMBASE, Web of Science and Cochrane databases were searched to collect correlational studies published in English between January 1949 and May 2018. Series reports that evaluating the oncological prognoses of patients with microinvasive cervical adenocarcinoma who were treated with fertility-sparing surgery versus hysterectomy were pooled for meta-analysis and trial sequential analysis. RESULTS A total of 8 articles with 1256 patients were collected, including 7 retrospective reviews and 1 prospective study. Only one (0.08%) patient had parametrial involvement. Positive margins of surgical specimens were identified in 6 patients (2.2%). Lymph node metastasis was found in 5 patients (0.4%). The progression-free survival and overall survival rates were 99.3 and 98.2%. Fertility-sparing surgery had no adverse impact on recurrence or survival (P = 0.524 and 0.485, respectively). Regarding potential selection bias, significantly more patients with stage IA2 tumors than those with stage IA1 disease were treated with hysterectomy (P < 0.001). The trial sequential analysis indicated that the cumulative number of patients failed to meet the required sample size (number of patients). CONCLUSIONS The prognosis for patients with microinvasive cervical adenocarcinoma is excellent. Fertility preservation is at least appropriate for young women with stage IA1 adenocarcinoma. Further studies are still warranted to evaluate the safety of this procedure in managing patients with microinvasive cervical adenocarcinoma.

Abstract
It is known that high-risk human papillomavirus infection is the main etiological factor in cervical carcinogenesis. However, human papillomavirus screening is not sufficient for early diagnosis. In this study, we aimed to identify potential biomarkers common to cervical carcinoma and human papillomavirus infection by proteomics for human papillomavirus-based early diagnosis and prognosis. To this end, we collected 76 cases of fresh cervical tissues and 116 cases of paraffin-embedded tissue slices, diagnosed as cervical squamous cell carcinoma, cervical intraepithelial neoplasia II-III, or normal cervix from ethnic Uighur and Han women. Human papillomavirus infection by eight oncogenic human papillomavirus types was detected in tissue DNA samples using a quantitative polymerase chain reaction. The protein profile of cervical specimens from human papillomavirus 16-positive squamous cell carcinoma and human papillomavirus-negative normal controls was analyzed by proteomics and bioinformatics. The expression of candidate proteins was further determined by quantitative reverse transcriptase-polymerase chain reaction and immunohistochemistry. We identified 67 proteins that were differentially expressed in human papillomavirus 16-positive squamous cell carcinoma compared to normal cervix. The quantitative reverse transcriptase-polymerase chain reaction analysis verified the upregulation of ASAH1, PCBP2, DDX5, MCM5, TAGLN2, hnRNPA1, ENO1, TYPH, CYC, and MCM4 in squamous cell carcinoma compared to normal cervix ( p < 0.05). In addition, the transcription of PCBP2, MCM5, hnRNPA1, TYPH, and CYC was also significantly increased in cervical intraepithelial neoplasia II-III compared to normal cervix. Immunohistochemistry staining further confirmed the overexpression of PCBP2, hnRNPA1, ASAH1, and DDX5 in squamous cell carcinoma and cervical intraepithelial neoplasia II-III compared to normal controls ( p < 0.05). Our data suggest that the expression of ASAH1, PCBP2, DDX5, and hnRNPA1, and possibly MCM4, MCM5, CYC, ENO1, and TYPH, is upregulated during cervical carcinogenesis and potentially associated with human papillomavirus infection. Further validation studies of the profile will contribute to establishing auxiliary diagnostic markers for human papillomavirus-based cancer prognosis.

Abstract
Cervical cancer screening involves a complex process of cytology, human papillomavirus (HPV) testing, colposcopy, and a multitude of algorithms for the identification of preinvasive disease and prevention of invasive disease. High-risk HPV is a prerequisite for the development of almost all types of cervical cancer; therefore, a test for high-risk HPV has become an integral part of new screening strategies. Major changes to screening guidelines in the last decade include initiation of screening at age 21 years, conservative management of young women with abnormal cytology, extended screening intervals for women age ≥30 years, and cessation of screening in low-risk women at age 65 years. This review will focus on the evidence that has led to the current evidence-based guidelines. Evidence regarding primary HPV testing as well as postvaccine-based screening strategies will also be reviewed.

Abstract
Nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) is overexpressed in various cancer tissues and may therefore contribute to oncogenesis. However, the status of NUCKS1 expression in cervical squamous cell carcinoma (CSCC) remains unknown. Immunohistochemistry was used to determine the expression of NUCKS1 protein in 30 cervical intraepithelial neoplasias (CINs) and 125 CSCCs compared with 20 normal cervical specimens. The correlationships of NUCKS1 protein overexpression with the clinicopathologic characteristics and clinical outcomes in patients with CSCC were analysed. The status of NUCKS1 expression was negative or weak in normal tissues, but high in 21 (70.0 %) CINs and in 44 (35.2 %) CSCCs. NUCKS1 overexpression was associated with advanced International Federation of Gynaecology and Obstetrics stage (P = 0.016), poor histologic grade (P = 0.040), large tumour size (P = 0.016), parametrial involvement (P = 0.025), deep stromal infiltration (P = 0.043), lymph node metastasis (P = 0.034) and recurrence (P < 0.001). Multivariate analysis suggested that NUCKS1 overexpression was an independent factor for recurrence-free survival (RFS) (hazard ratio, 2.193; 95 % confidence interval, 1.060 to 4.535; P = 0.034). In conclusion, NUCKS1 overexpression may be associated with tumour progression and recurrence in CSCCs and may thus serve as a new molecular marker for the prediction of RFS in these patients.

Abstract
OBJECTIVES The objective of this study was to explore the prognostic values of Yes-associated protein (YAP) expression in cervical carcinoma. METHODS We compared the YAP expression of 120 samples from squamous cell carcinomas (SCCs) and 42 samples from adenocarcinomas with 22 normal cervical specimens by immunohistochemistry. The expressions of cytoplasmic and nuclear YAP were analyzed separately. RESULT Yes-associated protein expression in tumors is significantly higher than the level in normal tissues. In SCCs, cytoplasmic YAP expression is associated with histologic grading, lymph node metastasis, and recurrence. Nuclear expression of YAP is absent in SCC. In adenocarcinomas, cytoplasmic YAP overexpression is associated with histologic grading, and nuclear overexpression is associated with shorter overall survival and disease-free survival. CONCLUSIONS Our results indicate the oncogenic potential of YAP in cervical cancer and its distinct functions in SCC and adenocarcinoma.

Abstract
AIM To evaluate utility of magnetic resonance imaging (MRI) in determining the primary site of endometrial versus cervical tumours when the biopsy results are inconclusive. MATERIAL AND METHODS Forty-eight patients who underwent a total hysterectomy for unknown primary adenocarcinoma of the uterus after endometrial and/or endocervical biopsies were included in the study. The 48 available pelvic MRI images were reviewed by two body radiologists independently and jointly to resolve discordance, blinded to any clinical and pathological information. The clinical information and histopathology were reviewed by a radiology fellow and a pathologist specializing is gynaecological oncology. The final surgical pathology was used as the reference standard to confirm the origin of the primary tumour. RESULTS The radiologists correctly identified the primary sites in 85% of the cases (41/48). There was substantial agreement between the two readers (kappa statistics = 0.79). Both radiologists found that T2 and dynamic T1-weighted images (WI) were most helpful in making the diagnosis, and dynamic T1WI helped resolve problematic cases. The sensitivity and specificity for detecting endometrial and cervical cancer on MRI were 88% and 88% and 75% and 93%, respectively. CONCLUSION MRI has high sensitivity and specificity in determining the origin of the primary endometrial versus cervical tumours when endometrial/endocervical curettage is inconclusive.

Abstract
Worldwide, cervical cancer is a leading cause of cancer related morbidity and mortality. For over 50 years, cervical cytology has been the gold standard for cervical cancer screening. Because of its profound effect on cervical cancer mortality in nations that have adopted screening programs, the Pap smear is widely accepted as the model screening test. Since its introduction, many studies have analyzed the Pap smear and found that it is not without its shortcomings including low sensitivity for detection of cervical intraepithelial neoplasia 2/3. Additionally, the discovery of infection with the human papillomavirus (HPV) as a necessary step in the development of cervical cancer has led to the development of HPV testing as an adjunct to cytology screening. More recently, researchers have compared HPV testing and cytology in the primary screening of cervical cancer. In this review, we will discuss cytologic testing limitations, the role of HPV DNA testing as an alternative screening tool, the impact of the HPV vaccine on screening, and future directions in cervical cancer screening.

Abstract
OBJECTIVE We compared the outcomes of microinvasive squamous cell carcinoma and adenocarcinoma of the cervix and examined the safety of fertility-conserving treatment. STUDY DESIGN The Surveillance, Epidemiology, and End Results database was used to identify all women with stage IA1 and IA2 cervical carcinoma diagnosed from 1988 to 2005. The treatment and outcomes of women with adenocarcinomas were compared with squamous cell carcinomas. RESULTS A total of 3987 women including 988 with adenocarcinomas (24.8%) were identified. Women with adenocarcinoma were more often white and were younger (P < .05 for all). Survival for stage IA1 adenocarcinomas (hazard ratio, 0.79; 95% confidence interval, 0.21-2.94) was similar to that of women with squamous cell tumors. For stage IA2 tumors, survival was similar for squamous cell and adenocarcinomas (hazard ratio, 0.51; 95% confidence interval, 0.18-1.47). For stage IA1 and IA2 adenocarcinomas, survival was similar for conization and hysterectomy. CONCLUSION Survival is similar for microinvasive adenocarcinomas and squamous cell carcinomas. Conization appears to be adequate treatment for microinvasive adenocarcinoma.

Abstract
PURPOSE To assess the value of magnetic resonance (MR) imaging in determining the site of origin of newly diagnosed uterine cancer (corpus vs cervix) when clinical and/or histologic evaluation is indeterminate. MATERIALS AND METHODS The Institutional Review Board approved and waived informed consent for this HIPAA-compliant study of 59 women (median age, 59 years; range, 28-84 years) who underwent pelvic MR imaging to determine the anatomic origin of uterine cancer. Two radiologists independently retrospectively assessed all MR imaging studies. In 48 patients who underwent hysterectomy, surgical pathologic findings were the reference standard, and overall test yields and diagnostic likelihood ratios were measured. Accuracy in detecting invasion of adjacent structures was also calculated. For the remaining patients, imaging and biopsy findings are presented descriptively. RESULTS At hysterectomy, 32 patients had uterine corpus cancer and 16 had cervical cancer. Overall test yields for reader 1 and reader 2 were 0.85 and 0.88, respectively. When a reader attributed a tumor's origin to either the uterine corpus or cervix, the odds of the tumor originating from that site were 4.80-6.35 times greater than they would have been if no other information were available. Accuracy levels in detecting invasion of the myometrium, cervical stroma, parametria and/or adnexae, and vagina, respectively, were 72%, 69%, 74%, and 85% for reader 1 and 78%, 77%, 76%, and 85% for reader 2. CONCLUSION MR imaging is useful for determining the anatomic origin of uterine cancer and provides helpful information regarding invasion of adjacent structures.

Abstract
Endometrial cancers exhibit a different mechanism of tumorigenesis and progression depending on histopathological and clinical types. The most frequently altered gene in estrogen-dependent endometrioid endometrial carcinoma tumors is PTEN. Microsatellite instability is another important genetic event in this type of tumor. In contrast, p53 mutations or Her2/neu overexpression are more frequent in non-endometrioid tumors. On the other hand, it is possible that the clear cell type may arise from a unique pathway which appears similar to the ovarian clear cell carcinoma. K-ras mutations are detected in approximately 15%–30% of endometrioid carcinomas, are unrelated to the existence of endometrial hyperplasia. A β-catenin mutation was detected in about 20% of endometrioid carcinomas, but is rare in serous carcinoma. Telomere shortening is another important type of genomic instability observed in endometrial cancer. Only non-endometrioid endometrial carcinoma tumors were significantly associated with critical telomere shortening in the adjacent morphologically normal epithelium. Lynch syndrome, which is an autosomal dominantly inherited disorder of cancer susceptibility and is characterized by a MSH2/MSH6 protein complex deficiency, is associated with the development of non-endometrioid carcinomas.

Abstract
PURPOSE Endometrial carcinoma (EC) is common in the population and the most frequent extracolonic malignancy in hereditary nonpolyposis colorectal carcinoma (HNPCC)/Lynch syndrome. We characterized precursor lesions of endometrioid EC to identify markers of malignant transformation and tumor progression. EXPERIMENTAL DESIGN Serial specimens of normal endometrium, simple hyperplasia, complex hyperplasia without atypia, complex hyperplasia with atypia, and endometrial carcinoma obtained during a 10-year surveillance of DNA mismatch repair (MMR) gene mutation carriers (together 110 samples) were molecularly profiled and compared with a sporadic reference series of endometrial specimens taken for nonmalignant reasons (62 samples). RESULTS Among MMR gene mutation carriers, decreased MMR protein expression was present in 7% in normal endometrium, 40% in simple hyperplasia, 100% in complex hyperplasia without atypia, 92% in complex hyperplasia with atypia, and 100% in endometrial carcinoma. Microsatellite instability frequencies were lower (6%, 17%, 67%, 38%, and 64%, respectively). Among 24 tumor suppressor genes, the number of methylated loci increased from normal endometrium to simple hyperplasia to complex hyperplasia (complex hyperplasia without atypia/complex hyperplasia with atypia) in both Lynch syndrome and reference series. The most frequently methylated genes were CDH13, RASSF1A, and GSTP1. In MMR gene mutation carriers, MMR and methylation defects appeared up to 12 years before endometrial carcinoma. CONCLUSIONS Molecular changes in endometrial tissue are detectable several years before endometrial carcinoma in genetically predisposed individuals. Abnormal MMR and methylation classify normal endometrium and simple hyperplasia into one category and complex hyperplasia without atypia, complex hyperplasia with atypia, and endometrial carcinoma into another, suggesting that, contrary to a traditional view, complex hyperplasia without atypia and complex hyperplasia with atypia are equally important as precursor lesions of endometrial carcinoma.

Abstract
High performance liquid chromatography with high sensitivity laser-induced fluorescence detection is used to study the protein profiles of serum samples from healthy volunteers and cervical cancer subjects. The protein profiles are subjected to principal component analysis (PCA). PCA shows that the large number of chromatograms of a given class of serum samples--say normal/malignant--can be expressed in terms of a small number of factors (principal components). Three parameters--scores of the factors, squared residuals, and Mahalanobis distance--are derived from PCA. The parameters are observed to have a narrow range for protein profiles of standard calibration sets formed from groups of clinically confirmed normal/malignant classes. Limit tests using match/no match of the parameters of any test sample with parameters derived for the standard calibration sets give very good discrimination between malignant and normal samples with high sensitivity (approximately 100%) aand specificity (approximately 94%).

Abstract
BACKGROUND Previous reports showed that mast cells can typically be found in the peritumoral stroma of cervix carcinomas as well as in many other cancers. Both histamine and TNF-alpha are potent preformed mast cell mediators and they can act simultaneously after release from mast cells. Thus, the effect of TNF-alpha and histamine on cervical carcinoma cell lines was studied. METHODS AND RESULTS TNF-alpha alone induced slight growth inhibition and cell cycle arrest at G0/G1 phase in SiHa cells, but increased their migration. Histamine alone had no effect on cells. In addition, TNF-alpha and histamine in combination showed no additional effect over that by TNF-alpha alone, although SiHa cells were even pretreated with a protein synthesis inhibitor. Furthermore, TNF-alpha-sensitive ME-180 carcinoma cells were also resistant to the combination effect of TNF-alpha and histamine. In comparison, TNF-alpha or histamine alone induced growth inhibition in a non-cytolytic manner in normal keratinocytes, an effect that was further enhanced to cell cytolysis when both mediators acted in combination. Keratinocytes displayed strong TNF receptor (TNFR) I and II immunoreactivity, whereas SiHa and ME-180 cells did not. Furthermore, cervix carcinoma specimens revealed TNF-alpha immunoreactivity in peritumoral cells and carcinoma cells. However, the immunoreactivity of both TNFRs was less intense in carcinoma cells than that in epithelial cells in cervical specimens with non-specific inflammatory changes. CONCLUSION SiHa and ME-180 cells are resistant to the cytolytic effect of TNF-alpha and histamine whereas normal keratinocytes undergo cytolysis, possibly due to the smaller amount of TNFRs in SiHa and ME-180 cells. In the cervix carcinoma, the malignant cells may resist this endogenous cytolytic action and TNF-alpha could even enhance carcinoma cell migration.

Abstract
OBJECTIVE Difficulties in detecting cervical adenocarcinoma early are well known. We report a detailed pathology review of cervical adenocarcinoma subtypes, comparing growth patterns and appearance of non-neoplastic epithelium to inform possible clues for disease progression and early detection. METHODS This analysis includes 154 women aged 18-69 years and diagnosed with incident in situ or invasive adenocarcinoma (AC), adenosquamous (AS), or other rare cervical glandular tumors from 1992-1996 in six U.S. medical centers. A pathology review panel evaluated histological features from original diagnostic slides. RESULTS Higher tumor grade (P < 0.001) and vascular invasion (P = 0.002) were more common in AS compared to AC. Adenocarcinoma in situ (AIS) was also more common among AC than AS (P = 0.002). Among AC with cervical intraepithelial carcinoma (CIN), AIS and cribriform patterns were more common than AC without CIN (P = 0.01). Further, non-endometrioid AC had higher tumor grade (P = 0.01) and stromal responses (P = 0.02) than endometrioid AC. Finally, although microglandular hyperplasia is historically thought to be related to oral contraceptive (OC) use, our data do not support this notion. CONCLUSION(S) AS appears to be either diagnosed later or histologically more aggressive than AC, and among AC subtypes, there are distinct histologic characteristics. Further research is needed to identify precursor lesions for early detection of AC and particularly for AS where AIS may not be a common precursor.

Abstract
OBJECTIVES We examined whether Medicaid beneficiaries are more likely to be diagnosed with late-stage cervical cancer than women not enrolled in Medicaid. METHODS Using the California Cancer Registry-Medicaid linked file, we identified 4682 women diagnosed during 1996-1999 with invasive cervical cancer. Multivariate logistic regression was used to evaluate the association between late-stage diagnosis and prediagnosis Medicaid status. RESULTS Late-stage disease was diagnosed in 51% of Medicaid and 42% of non-Medicaid women. Relative to women without Medicaid coverage, adjusted odds ratios for late-stage diagnosis were 2.8 times higher among women enrolled in Medicaid at the time of their diagnosis and 1.3 times higher among those intermittently enrolled before being diagnosed. Vietnamese women were less likely than White women to have advanced disease; the adjusted odds for women in other racial/ethnic groups did not differ from those among Whites. Women of low socioeconomic status and older women were at increased risk. CONCLUSIONS Women intermittently enrolled in Medicaid or not enrolled until their diagnosis were at greatest risk of a late-stage diagnosis, suggesting that more outreach to at-risk women is needed to ensure access to screening services.

Abstract
Cervical cancer is the second most common cancer among women worldwide, with significantly higher rates in developing areas, especially in Africa, the Caribbean, and Latin America (Parkin, Bray, Ferlay, & Pisani, 2005). In contrast, incidence and mortality rates of cervical cancer in the United States have declined significantly among women of all ethnic and racial groups; it is not among the top 10 leading causes of new cancer cases in women (American Cancer Society [ACS], 2006b; Edwards et al.,2005).

Abstract
Epithelial cells of fetal breast glandular structures, at the third trimester of pregnancy (28 weeks), produce GCDFP-15, in the absence of specific apocrine morphology. Apocrine epithelium of the breast may be a normal process of differentiation rather than a result of metaplasia, and it has been demonstrated that it is estrogen-receptor, progesterone-receptor and bcl-2 negative, but androgen-receptor (AR) positive. The significance of AR expression in apocrine epithelium is uncertain. Apocrine epithelium is seen in a wide spectrum of breast entities, ranging from benign lesions to invasive carcinoma. Breast cancer accounts 32% of all cancer cases among women and is the most common type of cancer in women. Little is known about breast carcinogenesis. Widely, it is accepted that breast cancer, like most other type of cancer, is being developed through the accumulation of genetic aberrations. Apocrine epithelium may reflect instability of the breast epithelium, creating an environment favouring further oncogenic alterations. In the last decade, several lines of evidence support the idea that some breast benign epithelial apocrine lesions are clonal lesions and may be considered as truly pre-malignant or precursors of breast carcinoma. Apocrine changes in many cases do not present any diagnostic difficulty; on the other hand, apocrine proliferations with cytologic atypia can be particularly difficult and challenging. The purpose of this study is to collect and highlight the areas of consensus in the literature as well as the controversial areas concerning the apocrine epithelium of the breast.

Abstract
Endocervical adenocarcinomas are rare and aggressive neoplasms. Papillary serous endocervical adenocarcinomas are the rarest form of endocervical adenocarcinomas. This tumor exhibits morphologic similarities to its counterparts commonly seen in the endometrium, fallopian tubes, ovaries, and peritoneum, which are known to have an aggressive behavior. Because of the rarity of this tumor, little is known about its immunophenotyping. In this study, we included ten cases of papillary serous carcinomas arising from the uterine cervix (PSCC) diagnosed in the absence of a primary endometrial malignancy. We studied their immunohistochemical profile, using a panel of antibodies against Ki67, bcl-2, p53, carcinoembryonic antigen (CEA), and CD10, and compared them to 20 consecutive cases of cervical adenocarcinoma of conventional cell subtypes (CAC) (15 mucinous, 3 adenosquamous, and 2 endometrioid). Immunostaining was recorded semiquantitatively. Patients with PSCC ranged in age from 27 to 79 years (mean = 51.6 +/- 19.1), while the conventional cell subtypes control group were 28-90 years old (mean = 47.5 +/- 16.9). Only p53 and CEA immunostaining significantly correlated with the PSCC morphology (P= 0.001 and P= 0.016, respectively) as shown by Cochran-Mantel-Haenszel Statistics (Modified Ridit Scores). PSCC is a distinctive immunophenotypic subtype of endocervical adenocarcinoma with significantly higher p53 and lower CEA reactivity than other more common histologic subtypes.
