Front Oncol 2023; 12:1074173. [PMID: 36686825 PMCID: PMC9848652 DOI: 10.3389/fonc.2022.1074173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 12/05/2022] [Indexed: 01/06/2023] Open
Abstract
Objectives As an ultrasound (US) image processing method, superb microvascular imaging (SMI) extracts and visualizes flow signals from vessels through advanced clutter suppression technology. We investigated the feasibility of SMI in monitoring treatment response in patients with locally advanced cervical cancer (LACC) undergoing chemoradiotherapy (CRT). Methods Forty-nine patients underwent CRT and received SMI examination at 3 time points: before therapy (baseline), 3 weeks during, and 1 month after CRT. The maximum tumor diameter (Dmax), vascularity index (VI), and their percentage changes (ΔDmax and ΔVI) were calculated. ΔDmax was compared with MRI results as the reference standard. Results Based on the MRI findings, 44 were classified as complete response (CR) group and 5 as partial response (PR) group. The Dmax and ΔDmax showed decrease in CR and PR groups at 3 weeks during CRT (P< 0.05), but no significant difference between the two groups (P > 0.05). Compared to the baseline, significant decrease in VI and ΔVI were observed at during and after treatment in the two groups (P< 0.05). Moreover, there were significant differences in VI and ΔVI at 3 weeks during CRT between the CR and PR groups (P< 0.05). ΔVI at 3 weeks during CRT showed a better predictive performance for responder prognosis than VI (AUC = 0.964, AUC = 0.950, respectively, P = 0.001), with a cut-off value of 41.6% yielding 100% sensitivity and 86.4% specificity. Conclusions The SMI parameters (VI and ΔVI) have potential for monitoring treatment response in LACC.

ADC and kinetic parameter of primary tumor: Surrogate imaging markers for fertility-sparing vaginal radical trachelectomy in patients with stage IB cervical cancer. Eur J Radiol 2022; 155:110467. [PMID: 35970120 DOI: 10.1016/j.ejrad.2022.110467] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 06/23/2022] [Accepted: 08/07/2022] [Indexed: 12/30/2022]
Abstract
PURPOSE To investigate the role of ADC and kinetic parameters derived from DCE-MRI in selecting eligible candidates for fertility-sparing vaginal radical trachelectomy (VRT). METHOD Female patients with FIGO stage IB cervical cancers between March 2019 and January 2022 were retrospectively included. All patients underwent hysterectomy and bilateral lymphadenectomy. According to the surgical pathology, the study population was divided into VRT-eligible group and VRT-ineligible group. ADC, semi-quantitative and quantitative kinetic parameters of the primary tumor were compared between the two groups. Logistic regression analysis was used to determine the independent predictors for VRT eligibility and ROC curve was used to evaluate the predictive performance. RESULTS 19 patients were deemed eligible for VRT and 50 were ineligible. Compared with VRT-eligible group, time to peak and ADC were significantly lower in VRT-ineligible group (P = 0.004 and 0.001, respectively) while volume fraction of plasma (Vp) was higher in VRT ineligible group (P = 0.001). ADC and Vp were independent predictors for VRT eligibility. Combining Vp and ADC yielded the highest area under the ROC curve of 0.853 compared with that of 0.766 for Vp and 0.764 for ADC, though marginal differences were found (P = 0.109 and 0.078, respectively). CONCLUSIONS ADC and the kinetic DCE-MRI parameter Vp can be used as surrogate markers to select eligible candidates for fertility-sparing VRT.

Assessment of cervical vascularization density in patients with locally advanced squamous cell cervical carcinoma evaluated in colour Doppler and power Doppler functions. Arch Gynecol Obstet 2021; 305:955-961. [PMID: 34586470 PMCID: PMC8969035 DOI: 10.1007/s00404-021-06161-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Accepted: 07/27/2021] [Indexed: 11/27/2022]
Abstract
Purpose The aim of the prospective study was to assess changes during treatment and prognostic significance of cervical vascularization density in patients with cervical squamous cell carcinoma (SCC) staged II B and III B and to find relationship of cervical vascularization density with tumour diameter, grading, staging and age of patients. Methods The study group included 50 patients who underwent transvaginal Doppler ultrasonography prior to chemoradiotherapy, after external beam radiation therapy (EBRT) and 6 weeks after HDR brachytherapy. The colour Doppler (CD) vascularity index (CDVI) and the power Doppler (PD) vascularity index (PDVI) in cervical tumour were examined. Results CDVI and PDVI values decreased significantly during radiotherapy (0.13 (95% CI 0.09–0.16); 0.09 (95% CI 0.07–0.11) and 0.05 (95% CI 0.03–0.06) for CDVI (p < 0.001) and 0.26 (95% CI 0.22–0.31); 0.18 (95% CI 0.14–0.22) and 0.08 (95% CI 0.06–0.11) for PDVI (p < 0.001)). No statistically significant associations of CDVI and PDVI with tumour diameter, grading, staging and age of patients were found. The higher (above median) CDVI values before EBRT were associated with better OS (p = 0.041). The higher (above median) PDVI values before EBRT were associated with superior DFS (p = 0.011) and OS (p < 0.001). DFS and OS did not differ significantly regarding CDVI and PDVI values after EBRT and after the treatment. Conclusions In the study group, cervical vascularization density evaluated in CD and PD functions did not depend on tumour diameter, grading, staging and age of patients and decreased during radiotherapy. The prognosis for our patients with CDVI and PDVI before the treatment above the median value was better than compared to patients with these parameters below the median value.

Abstract
AIM This study evaluates the feasibility of handheld vital microscopy for noninvasive, objective assessment of the microcirculation of the human uterine cervix. We qualitatively and quantitatively describe the microcirculation in healthy subjects in order to provide a basis for its application in cervical pathology. METHODS Incident dark field imaging was used to image the microcirculation in four quadrants of the uterine ectocervix in ten healthy participants. If the squamocolumnar junction was visible, measurements were repeated on the endocervical columnar epithelium as well. Image acquisition time was recorded and participants scored the experienced level of discomfort. Angioarchitecture was classified according to Weber's classification. Quantitative parameters included capillary density (CD), total and perfused vessel density (TVD, PVD), proportion of perfused vessels (PPV) and microvascular flow index (MFI). RESULTS Image acquisition was easy, fast and well tolerated. Angioarchitecture was characterized by two distinctive and organized patterns; capillary loops underneath the squamous epithelium of the ectocervix and vascular networks underneath the columnar epithelium. In the image sequences containing capillary loops, mean CD was 33.2 cpll/mm2 (95% CI 28.2-38.2 cpll/mm2). In the image sequences with vascular networks, mean TVD was 12.5 mm/mm2 (95% CI 11.2-13.77 mm/mm2), mean PVD was 12.2 (95% CI 11.0-13.5 mm/mm2), MFI was 3 and PPV was 100%. CONCLUSIONS Incident dark field imaging allows for noninvasive, real time visualization and objective evaluation and quantification of the microcirculation of the uterine cervix. The organized vascular patterns and optimal perfusion observed in healthy subjects allow for comparison with cervical pathology, for example in patients with cervical dysplasia or cervical cancer.

Abstract
The utility of placental growth factor (PlGF) and its receptor VEGFR-1 (Flt-1) as biomarkers for cervical cancer has not been clarified yet. To address this issue, we investigated the levels of soluble PlGF (sPlGF) and soluble Flt-1 (sFlt-1) in the serum from patients with early cervical cancer, cervical intraepithelial neoplasia (CIN) and controls in this study. sPlGF and sFlt-1 were detected in 44 preoperative patients with cervical cancer, 18 cases with CIN, and 20 controls by ELISA. It was found that both sPlGF and sFlt-1 were significantly increased in the cervical cancer group as compared with those in CIN and control groups. sPlGF presented a high diagnostic ability of cervical cancer, with a sensitivity of 61.36% and a specificity of 89.47%; and sFlt-1 with a sensitivity of 50.00% and a specificity of 92.11%. Importantly, the combined use of sPlGF and sFlt-1 could increase the diagnostic rate of cervical cancer, with a sensitivity of 70.45% and a specificity of 92.11%. These results indicated that both sPlGF and sFlt-1 in circulation can serve as possible valuable diagnostic biomarkers for cervical cancer, and the combined use of them can be more valuable to diagnose the patients with early cervical cancer.

Abstract
Angiogenesis is required in cancer, including gynecological cancers, for the growth of primary tumors and secondary metastases. Development of anti-angiogenesis therapy in gynecological cancers and improvement of its efficacy have been a major focus of fundamental and clinical research. However, survival benefits of current anti-angiogenic agents, such as bevacizumab, in patients with gynecological cancer, are modest. Therefore, a better understanding of angiogenesis and the tumor microenvironment in gynecological cancers is urgently needed to develop more effective anti-angiogenic therapies, either or not in combination with other therapeutic approaches. We describe the molecular aspects of (tumor) blood vessel formation and the tumor microenvironment and provide an extensive clinical overview of current anti-angiogenic therapies for gynecological cancers. We discuss the different phenotypes of angiogenic endothelial cells as potential therapeutic targets, strategies aimed at intervention in their metabolism, and approaches targeting their (inflammatory) tumor microenvironment.

Abstract
Clinicopathological characteristics alone are not enough to predict the survival of patients with cervical squamous cell carcinoma (CESC) due to clinical heterogeneity. In recent years, many genes and non-coding RNAs have been shown to be oncogenes or tumor-suppressors in CESC cells. This study aimed to develop a comprehensive transcriptomic signature for CESC patient prognosis. Univariate, multivariate, and Least Absolute Shrinkage and Selection Operator penalized Cox regression were used to identify prognostic signatures for CESC patients from transcriptomic data of The Cancer Genome Atlas. A normalized prognostic index (NPI) was formulated as a synthetical index for CESC prognosis. Time-dependent receiver operating characteristic curve analysis was used to compare prognostic signatures. A prognostic transcriptomic signature was identified, including 1 microRNA, 1 long non-coding RNA, and 6 messenger RNAs. Decreased survival was associated with CESC patients being in the high-risk group stratified by NPI. The NPI was an independent predictor for CESC patient prognosis and it outperformed the known clinicopathological characteristics, microRNA-only signature, gene-only signature, and previously identified microRNA and gene signatures. Function and pathway enrichment analysis revealed that the identified prognostic RNAs were mainly involved in angiogenesis. In conclusion, we proposed a transcriptomic signature for CESC prognosis and it may be useful for effective clinical risk management of CESC patients. Moreover, RNAs in the transcriptomic signature provided clues for downstream experimental validation and mechanism exploration.

Abstract
BACKGROUND The present study explored the expression of coiled-coil domain-containing 34 (CCDC34) in cervical cancer (CC) and its prognostic value. MATERIAL AND METHODS GEPIA and Oncomine cancer databases were mined to predict the CCDC34 differential expression level between a CC group and a normal group. Immunohistochemistry was performed to examine the CCDC34 expression in 67 CC and corresponding adjacent tissues. CD31 and vascular endothelial growth factor (VEGF) were stained to reflect tumor angiogenesis in 67 CC tissues. Kaplan-Meier univariate and Cox multivariate survival analysis were done to evaluate the correlation between CCDC34 expression and prognosis of CC patients. RESULTS Both GEPIA and Oncomine cancer databases mining results revealed that CCDC34 was more highly expressed in the CC group than in the normal group (all P<0.05). Our immunochemical staining data showed that CCDC34 expression was dramatically higher in CC than in adjacent normal tissues (71.6 vs. 20.9%; P<0.001). High expression of CCDC34 was strongly associated with histological grade (P=0.022), lymph node metastasis (P=0.044), and FIGO stage (P=0.002). Furthermore, patients with CCDC34-positive expression had much more MVD than those with CCDC34-negative expression (P<0.001). Kaplan-Meier survival analysis showed that CCDC34-positive expression was associated with worse overall survival (OS) (P=0.004) and disease-free survival (DFS) (P=0.005). Additionally, Cox multivariate analysis revealed that CCDC34 was an independent unfavorable prognostic parameter of DFS and OS (P=0.040 and 0.039, respectively). CONCLUSIONS High expression of CCDC34 is an independent unfavorable prognostic parameter for OS and DFS of CC patients, which was strongly associated with tumor angiogenesis.

Abstract
Background Three-dimensional power Doppler ultrasound (3D-PDU) imaging has been widely applied to the differentiation of benign and malignant cervical lesions; however, its potential value for predicting response to chemo-radiotherapy has not been fully explored. Purpose To investigate the feasibility of 3D-PDU imaging in predicting treatment response in patients receiving concurrent chemo-radiotherapy (CCRT) for advanced cervical cancer. Material and Methods Fifty-two patients with advanced cervical cancer who received CCRT underwent 3D-PDU examinations at four timepoints: pre-therapy (baseline), 1 week and 2 weeks during, as well as immediately post CCRT. Final tumor response was determined by change in tumor size using magnetic resonance imaging (MRI). Cervical tumor volumes and vascular indices were calculated and compared with the clinical outcome. Results Of the 52 patients, 32 patients who completed all four examinations were included in the analyses: 21 were classified as complete response (CR) and 11 as partial response (PR). During the treatment, the CR group showed that 3D vascular indices (VI and VFI) significantly increased at 1 week ( P = 0.028, P = 0.017, respectively) then decreased at 2 weeks and obviously decreased at therapy completion (both P < 0.001), whereas tumors significantly decreased in volume at 2 weeks after therapy initiation ( P < 0.05). However, no significant differences in 3D vascular indices values were seen in the PR group during the treatment course (all P > 0.05). Conclusion Prospective longitudinal 3D-PDU imaging may have potentials in monitoring early therapeutic response to CCRT in patients with cervical cancer.

To determine whether vascular endothelial growth factor (VEGF) expression and microvessel density are predictive of prognosis in cases of invasive cervical cancer, correlations among VEGF expression, microvessel density, and clinicopathological parameters were identified. VEGF expression was evaluated in 50 cervical cancer samples by immunohistochemical staining. Microvessel density was assessed by immunostaining for CD31-positive endothelial cells in the most vascularized areas of tumors. VEGF expression and microvessel density were significantly higher in adenocarcinomas than in squamous cell carcinomas. However, in cases of adenocarcinoma, no significant correlations were found among VEGF expression, microvessel density, and clinicopathological parameters. In contrast, for squamous cell carcinomas, microvessel density was significantly higher in cases at an advanced stage and in those with several other poor prognostic factors. The finding that cervical adenocarcinomas exhibited greater VEGF expression and microvessel density than squamous cell carcinomas may explain the poorer prognosis of adenocarcinoma compared with squamous cell carcinoma. Moreover, microvessel density in squamous cell carcinomas was significantly correlated with poor prognostic factors. Therefore, there is possibility that bevacizumab, a humanized monoclonal antibody against VEGF-A, may be useful in the initial treatment targeting angiogenesis for early-stage cervical cancer.

Abstract
Cervical cancer (CC) is one of the most common malignancies affecting women worldwide. While the morbidity and mortality associated with CC are decreasing in western countries, they both remain high in developing countries. Unfortunately, many issues about molecular mechanisms of CC are not clear yet. miRNAs are a group of small noncoding RNAs that could post-transcriptionally modulate the expression of specific genes and participate in the initiation and progression of multiple diseases including CC. In the last decade, mounting evidences suggest an association between miRNAs and human papillomavirus infection, as well as variations in biologic behavior, treatment response and prognosis in CC. Herein, we highlight the latest findings in this area and the potential applications.

Abstract
PURPOSE The purpose of this study was to provide an overview of current and up and coming targeted therapies in cervical cancer with or without chemotherapy. METHODS We reviewed the literature using search terms cervical cancer AND immunotherapy, immune therapy, vaccines, bevacizumab, anti-angiogenic therapy, and PARP inhibitors on PubMed. We included all review articles and prospective trials. We also reviewed ClinicalTrials.gov for trials in progress. FINDINGS The addition of bevacizumab has improved the overall survival of women with advanced or recurrent cervical cancer when compared with cytotoxic therapy alone. This advancement has sparked an interest in other anti-angiogenic agents. Additionally, targeted therapies, including tyrosine kinase inhibitors, immunotherapy, and vaccine therapy, are also being evaluated. Another exciting area of study is the role of poly (ADP-ribose) polymerase inhibition in cervical cancer. IMPLICATIONS Though the results are promising, the data are preliminary and additional studies evaluating the proper combination of therapy, dosing, and schedules will help inform the ideal regimen.

Abstract
OBJECTIVE The aim of this study was to assess the potential role of 3-dimensional power Doppler ultrasound (3D-PDUS) for predicting clinical response and recurrence after chemoradiotherapy in advanced-stage cervical cancer. METHODS This is a prospective study comprising a series of women with histological proven diagnosis of locally advanced stage (stage IB2-IVA) carcinoma of the cervix and submitted to chemoradiaton therapy. Before the start of chemoradiation therapy, all women were submitted to undergo transvaginal 3D-PDUS for assessing tumor volume and tumor vascularization. After finishing chemoradiation, all women were evaluated to assess clinical response. Complete clinical response was determined when no residual tumor was apparent. Partial clinical response (PCR) was determined when persistent residual tumor was observed and confirmed by histological analysis. Patients with PCR underwent salvage surgery. Local recurrence was defined as reappearance of the tumor within the pelvis at any time during follow-up. RESULTS Thirty-nine women (mean age, 50.3 years; ranging from 30 to 81 years) were included in the study. Complete clinical response was achieved in 29 women (70.7%), whereas 10 women (24.4%) had PCR. Eight women (20.5%) had local recurrence during follow-up. We did not find statistical significant differences in tumor size, volume, and vascularization between those women who had complete clinical response and those who had PCR and between those who had local recurrence and those who had not. CONCLUSIONS A single 3D-PDUS assessment of tumor size and vascularization before treatment seems to be of limited value for predicting tumor response to chemoradiation therapy and for predicting tumor recurrence in women with locally advanced carcinoma of the cervix.

Abstract
B7-H3 is a transmembrane protein and a member of the B7 family of immune regulatory ligands. It exerts both inhibitory and stimulatory effects on the activation of T cells. We investigated the expression of B7-H3 in invasive squamous cell carcinoma (ISCC) of the uterine cervix by immunohistochemistry, and aimed to determine whether expression of this factor is involved in the progression of the morphologic spectrum from normal cervical epithelia to cervical intraepithelial neoplasia and cervical ISCC. In addition, we sought to examine the relation of B7-H3 to the abundance of tumor-infiltrating and tumor-associated CD8(+) lymphocytes and to the evidence of phosphohistone H3, which is a core histone protein detected during mitosis. B7-H3 immunostaining was scored with regard to quantity and intensity of positively stained cells, and was noted in membranous and cytoplasmic patterns in epithelial cells and on endothelia of stromal blood vessels. Compared with those in intraepithelial neoplasias, immunoscores were significantly increased in ISCC (P<0.0001 for epithelial and endothelial expression, respectively). High scoring was associated with International Federation of Gynecology and Obstetrics stages IB and higher. Immunoscores of epithelial and endothelial B7-H3 expression were correlated significantly (P=0.0358). Epithelial and endothelial expression of B7-H3 was inversely related with CD8(+) tumor-infiltrating lymphocyte (P<0.0001). Moderate/strong B7-H3 epithelial as well as endothelial expression was mutually increased with intermediate/strong phosphohistone H3 scores (P=0.0396 and P=0.0483, respectively). There was no statistical relation with survival; however, no patient with negative scoring died of her tumor. Our results indicate that B7-H3 expression in cervical ISCC may play an important role in overcoming CD8(+) T-cell immunoregulation to acquire aggressive growth.

Abstract
Gynecologic malignancies carry an estimated incidence of 83,750 cases per year and estimated mortality rate of more than 27,000 women per year. New therapies and therapeutic approaches are needed to improve the outlook for women with gynecologic cancers. Recent insights at the molecular and cellular levels are paving the way for a more directed approach to target mechanisms driving tumorigenesis. This article reviews the roles of new and emerging antiangiogenesis drugs, summarizes the data obtained from clinical trials of antiangiogenic agents, and discusses trials under way to address the role of such strategies in gynecologic cancers.

Abstract
Unlike its cutaneous counterpart, prognostic markers for primary mucosal malignant melanoma have not been well elucidated. It has been recently demonstrated that microvascular density (MVD) in cutaneous malignant melanoma has a significant negative correlation with survival; however, this has not been well-studied in mucosal malignant melanoma of the head and neck. This study explores the potential association between MVD, various histological parameters, and the outcome of a series of sinonasal and oral mucosal melanomas. Nineteen such cases were immunostained with CD31 and the MVD was calculated by using Bioquant Image Analysis Software (R and M Biometrics, Nashville, TN). These cases included 16 sinonasal and 3 oral cavity tumors. The 1, 2, 3, 4 and 5 years overall survival rates were 75, 57, 61, 46 and 46%, respectively. The MVD of the tumors ranged from 25.7 to 732 vessels/mm(2) (mean 142.8 vessels/mm(2); median 84.7 vessels/mm(2)). There was no significant correlation between the MVD and the different clinicopathological features seen within the tumors. There was also no correlation between the MVD and relapse free and overall survival. The results of this study suggest that MVD does not correlate with outcome in mucosal melanoma of the head and neck as seen in cutaneous melanomas. Further larger studies are needed to identify predictive and prognostic markers in such melanomas.

Abstract
Cytotoxic therapy and surgery have improved outcomes for patients with gynecologic malignancies over the last twenty years, but women's cancers still account for over ten percent of cancer related deaths annually. Insights into the pathogenesis of cancer have led to the development of drugs that target molecular pathways essential to tumor survival including angiogenesis, DNA repair, and apoptosis. This review outlines several of the promising new biologically targeted drugs currently being tested to treat gynecologic malignancies.

Abstract
The carcinogenesis of cervical carcinoma implies an intricate interplay of neoplastic, human papillomavirus infected epithelial cells and stromal tissue, in which different factors have distinct but interacting influence. Persistent infection with an oncogenic human papillomavirus type may lead to epithelial dysplasia with progressive severity. To access the adjacent stromal tissue, tumour cells have to breach the basement membrane. The stroma partly controls tumour growth, invasion and angiogenesis. Last but not least there is considerable influence of the immune response. In this review we describe the importance of various stromal factors in carcinogenesis of cervical cancer.

The biologic rationale for targeting vascular endothelial growth factor (VEGF) for these disease sites is well-founded, and pre-clinical studies have supported the development of anti-VEGF agents. Their classification, known mechanisms of action, unique toxicities and clinical development are herein explored, the latter including issues related to study design, disease site and disease setting.

Abstract
OBJECTIVES To determine whether markers of tumor angiogenesis were associated with progression-free survival (PFS) and overall survival (OS) in women with high-risk, early-stage cervical cancer treated on a phase III trial. METHODS One hundred seventy-three tumor specimens were analyzed by semi-quantitative immunohistochemical (IHC) staining for vascular endothelial growth factor (VEGF, pro-angiogenesis factor), thrombospondin-1 (TSP-1, anti-angiogenesis factor), CD31 (non-specific endothelial marker), and CD105 (tumor-specific endothelial marker). Tumoral histoscores (HS) were calculated for VEGF using the formula: [% cells positivex(intensity+1)]. TSP-1 specimens were categorized as negative or positive. CD31 and CD105 microvessel density (MVD) "hotspots" were counted in three 20x high-power fields. Associations between angiogenesis markers and survival were evaluated. RESULTS TSP-1 expression was observed in 65% of cases while 66% expressed high VEGF (>or=200), 34% exhibited high CD31 (CD31>or=110) and 66% displayed high CD105 (CD105>or=28). In univariate analyses CD31 MVD, but not tumor TSP-1, was associated with improved PFS (HR=0.37; 95% CI=0.18-0.76; p=0.007) and OS (HR=0.37; 95% CI=0.17-0.79; p=0.010). After adjusting for prognostic clinical covariates, high CD31 MVD, but not TSP-1, VEGF or CD105 MVD, was an independent prognostic factor for PFS (HR=0.36; 95% CI=0.17-0.75; p=0.006) and OS (HR=0.36; 95% CI=0.17-0.79; p=0.010). CONCLUSIONS Tumor angiogenesis measured by CD31 MVD is an independent prognostic factor for both PFS and OS in high-risk, early-stage cervical cancer. We hypothesize that this finding may be explained by improved treatment response in well-vascularized, well-oxygenated tumors.

Abstract
For a tumor to grow beyond a limited volume of 1-2 mm(3), the tumor cells must not only proliferate, but they must be able to induce the growth of new capillary blood vessels from the host. As early as 1971, it was proposed that tumor growth was dependent on angiogenesis; and, that tumor cells and blood vessels composed a highly integrated ecosystem, that endothelial cells could be switched from a resting state to one of rapid growth by a diffusible signal from tumor cells, and that anti-angiogenesis may become an effective anti-cancer therapy. Indeed, now there is considerable indirect and direct evidence to show that tumor growth is angiogenesis dependent, that tumor cells can produce diffusible angiogenic regulatory molecules, and that angiogenesis inhibitors can slow or prevent tumor growth, and that angiogenesis is a relevant target for anti-cancer therapy. Measuring intratumoral microvessel density (iMVD) in vascular "hot spots" has been shown to correlate with aggressive tumor behavior. This chapter reviews the techniques available for measuring iMVD.

Abstract
The objective of this study is to evaluate angiogenesis in cervical intraepithelial neoplasia (CIN), microinvasive squamous cell carcinoma (MIC), and early-staged squamous cell carcinoma (SCC), stage IB-IIA of the cervix. Microvessel density (MVD) was evaluated and correlated with other pathologic prognostic factors and disease outcomes. Four hundred seventy-four cervical specimens were studied. Among these, 100 were designated normal cervix, 30 CIN1, 32 CIN2, 178 CIN3, 74 MIC, and 60 early-staged SCC. MVD per high-power field (x400) of early-staged SCC, MIC, and CIN3 were significantly higher in comparison to CIN2, CIN1, and control subjects (P<0.05). There was no statistically significant difference in MVD between control group, CIN1, and CIN2. In early-staged SCC, no correlation between MVD and pelvic lymph node status, parametrial involvement, depth of stromal invasion, and lymphovascular space invasion was found. Patients with bad outcomes (recurrence or death) showed no statistically different MVD from the ones who had unremarkable clinical courses.

Abstract
Lymph node metastases is an important prognostic indicator for disease progression and crucial for therapeutic strategies in the work-up of colorectal carcinoma. In this study, we investigated tumor lymphangiogenesis and vascular endothelial growth factor (VEGF) expression as predictive markers for the risk of lymph node metastasis and their relation to other prognostic parameters in colorectal carcinoma. Resected colorectal carcinomas from 90 patients were examined, including 30 patients without lymph node metastases, 30 with only lymph node metastases, and 30 with liver metastases. Cases were immunostained for CD31, D2-40, and VEGF. Positivity stained microvessels were counted in densely vascular/lymphatic foci (hot spots) at x 400 field (=0.17 mm2). Intensity of staining for VEGF was scored on a two-tiered scale. D2-40 lymphatic microvessel density demonstrated significant correlation with CD31 counts (20+/-9 vs 18+/-6/0.17 mm2 field, P<0.05) and VEGF expression (P<0.01). VEGF was expressed in 61/90 (67%) cases. D2-40 identified lymphatic tumor invasion in 48/90 patients, which was greater than CD31 (37/90) and hematoxylin and eosin (H&E) (31/90). There was a positive significant correlation of D2-40, CD31 counts, and VEGF expression with the presence of lymphovascular invasion and lymph node metastases (P<0.05). D2-40 lymphatic microvessel density correlated significantly with depth of invasion (pT), positive vascular pedicle lymph nodes and liver metastases (P<0.05). In conclusion, D2-40 lymphatic microvessel density showed prognostic significance with positive correlation with lymphovascular invasion, pT, and metastases to lymph nodes and liver. Immunostaining with D2-40 enhances the detection of lymphatic invasion relative to H&E staining and the endothelial marker, CD31.

Abstract
Lymphatic vessel density (LVD) was recently considered important for spread of several malignant tumors. However, there are no reports describing the situation in cervical carcinoma. The purpose of this study was to investigate whether LVD could serve as a risk factor for nodal metastasis and recurrence of cervical carcinoma in 147 cases of stage I patients. Other questions were if depth of invasion, proliferation rate, and tumor size could be used as predictive markers for Chinese patients with cervical carcinoma. The lymphatics were determined by immunohistochemistry with the antibody to LYVE-1, a specific lymphatic endothelium marker, and average LVD was calculated. Double immunohistochemistry and double immunofluorescence staining for LYVE-1/CD34 were used to distinguish between lymphatic and blood vessels. The results showed that average LVD in cervical carcinoma was statistically associated with inflammatory cell infiltration of carcinoma tissues, but not associated with other pathological parameters. Average LVD of the cases with nodal metastasis or recurrence was significantly higher than the cases without metastasis and recurrence in both stage IA and stage IB cervical carcinomas. The correlation between both depth of invasion and tumor size with nodal metastasis and recurrence of cervical carcinoma was also statistically significant. Ki-67 labeling index was found to be correlated with the recurrence of disease, but not to be correlated with nodal metastasis. We concluded that for the patients with stage I cervical carcinoma, increased LVD could serve as a high-risk factor for nodal metastasis and recurrence. Depth of invasion and tumor size could also be useful indicators.

Abstract
Hypoxia and/or anaemia have an adverse prognostic impact in locally-advanced cancers of uterine cervix. Moreover, these parameters are independent of other well-known prognostic factors. However, the mechanisms by which treatment efficacy and survival are compromised by anaemia are not fully understood. Although it is clear that erythropoietin can reduce the need for transfusions for cancer patients with anaemia, there is no proof that the use of erythropoietin is in any way superior to transfusions with respect to the impact on clinical outcome, especially for patients receiving radiation therapy. Whether haemoglobin levels at the start of therapy, during therapy, or at the end of therapy are of prognostic value for better disease-free and overall survival, are matters for further studies as is the question of the best option for increasing the level of the patient's haemoglobin.

Abstract
Carcinomas of the cervix may be categorized on morphological grounds into four main groups: squamous carcinomas; adenocarcinomas; neuro-endocrine tumours; and others including adenosquamous carcinomas. Each group contains several morphological subvariants. Invasive squamous carcinomas and adenocarcinomas are preceded by cervical intra-epithelial neoplasia and cervical glandular intra-epithelial neoplasia, respectively. Each is graded into low and high grade. Micro-invasive carcinomas with stromal invasion less than 3mm in depth have a minimal chance of lymph node metastasis. When there is lymph node involvement, the obturator node may be the most common. Presence or absence of lymph node involvement, tumour size and depth of invasion are the important independent histopathological indicators of prognosis. The presence or absence of vascular space invasion is a valuable prognostic indicator. Small cell carcinomas, large cell neuro-endocrine carcinomas and possibly adenoid cystic carcinomas are aggressive. With these exceptions, it is doubtful whether tumour type is of much clinical significance. Tumour grade, as currently assessed, is of no significant value.

Abstract
Lymphatic invasion and nodal metastasis are predictors of shorter disease-free and overall survival in carcinoma of the uterine cervix. The monoclonal antibody D2-40, which reacts with the oncofetal membrane antigen M2A, is a new selective marker for lymphatic endothelium, and has been shown to be useful in identifying the presence of lymphatic invasion in various malignant neoplasms, including cervical carcinoma. However, the reactivity of the tumor cells with D2-40 has not yet been evaluated. In this study, we examined the pattern of D2-40 immunoreactivity in a series of 138 invasive squamous cell carcinomas of the uterine cervix. We correlated the presence and extent of D2-40 immunoreactivity in the tumor cells with various clinicopathologic features, the presence of lymphatic invasion, lymph node metastasis and outcome. Diffuse or focal D2-40 immunoreactivity was present in 17 (12%) and 81 (59%) tumors, respectively, while 40 (29%) tumors showed no immunoreactivity. Lymphatic invasion and nodal metastasis were present in 56 and 29% of tumors, respectively. Tumor emboli within lymphatic spaces and metastatic tumor foci in lymph nodes showed no immunoreactivity in 86 and 80% of the cases, respectively. Lymphatic invasion and nodal metastasis were significantly more common in tumors showing low D2-40 immunoreactivity (P<0.0001 and 0.022, respectively). D2-40 immunoreactivity showed no correlation with any other clinicopathologic features examined, including tumor size, grade and FIGO stage. In univariate analysis low D2-40 immunoreactivity was significantly associated with shorter recurrence-free, but not with overall survival. Our studies suggest that D2-40 immunostaining may serve as a marker for increased risk of lymphatic invasion and tumor recurrence in cervical biopsy material. Further study of the biological function of the M2A antigen may shed some light on the interaction of tumor cells with lymphatics.

Abstract
AIMS Intratumoural micro-vessel density (IMD) has recently been shown to be a valuable prognostic tool in many tumours. Yet, IMD does not take into account the spatial arrangement of the vessels, therefore only partly reflecting the angiogenic situation. In order to describe contextual vascular relationships more accurately, we have used fractal and syntactic structure analysis (SSA) based on computerised image processing to quantify micro-vascular hot spots. MATERIALS AND METHODS The parametric performance in prediction of patients' outcome was evaluated by univariate analysis and compared with manually obtained IMDs, whereas an automated K-nearest-neighbour (KNN) classifier searched most discriminative parametric combinations. The method is based on analysis of vascular 'hot-spots' of paraffin-embedded tissue sections of invasive cervical carcinoma, colorectal carcinoma and malignant mesothelioma. RESULTS For all three cancers, prediction of prognosis based on SSA yielded in general much higher recognition scores compared with IMD or fractal dimension. Survival of cervical carcinoma was mostly correlated with clinical data, with the vascular permeation being the only parameter with independent value. Prognosis of colorectal carcinoma is best described by SSA, completed with IMD, indicating an inverse correlation of survival time with a more irregular pattern and a slight increase in vessel number. For mesothelioma, we found a strong correlation with SSA and patients' outcome, with two SSA-parameters having independent prognostic value. CONCLUSIONS The more accurate angiogenic description obtained with SSA may be useful for further exploitation as a prognosticator in a general diagnostic pathology service.

Abstract
PURPOSE This study was conducted to evaluate the potential role of transvaginal color Doppler sonography (TVCD) in predicting response to concurrent chemoradiotherapy for locally advanced cervical cancer. METHODS AND MATERIALS Tumor vascularity was assessed using TVCD before the start of concurrent chemoradiotherapy in 21 patients (median age, 47 years; range, 31-75 years) with histologically proven locally advanced cervical cancer. The lowest resistance index (RI), lowest pulsatility index (PI), and highest peak systolic velocity (PSV) from central vessels within the tumor were recorded and used for analysis. All patients were clinically evaluated by physical examination and CT scanning after completing the chemoradiotherapy protocol. Complete clinical response (CR) was determined when no residual tumor was found. Partial clinical response (PR) was determined when the tumor volume had decreased more than 50%. RESULTS CR was achieved in 11 patients (52%), whereas 10 (48%) had PR. The initial median tumor volume was not statistically different between those with CR (26 cm3) and those with PR (28 cm3) (p = 0.71). RI was higher in those tumors with CR (median, 0.47) than in those with PR (median, 0.29) (p < 0.01). Likewise, PI was higher in tumors with CR (median, 0.81) than in those with PR (median, 0.41) (p < 0.01). No differences were found in PSV. The likelihood ratio for CR for tumors with a lowest RI of 0.35 or more was 2.7 (95% confidence interval, 1.8-3.6) and the likelihood ratio for CR for tumors with a lowest PI of 0.45 or more was 3.3 (95% confidence interval, 2.1-4.5). CONCLUSIONS The results suggest that TVCD may be useful in predicting clinical response to concurrent chemoradiation in patients with locally advanced cervical cancer.

Abstract
The purpose of this retrospective study of 118 patients with squamous cell cervical cancer from January 1990 to December 1993 was to evaluate angiogenesis as predictive factor of recurrence in cervical cancer stages II-III treated with standard radiotherapy. Microvessel density (MVD) was evaluated and correlated with other prognostic factors. MVD was greater than 20 in 67.8% of patients with recurrence (P = 0.002) in comparison to 39% of patients without. Disease-free survival was shorter in stage IIA and MVD >20 (P = 0.0193) as well as for stage IIB (P < 0.05 ), but not for IIIB (P = 0.1613 ). Global survival was significantly shorter when MVD was >20 (P = 0.0316). For stage IIA and MVD >20 survival was shorter (P = 0.0008) for stage IIB (P < 0.05) but not for IIIB (P = 0.14). Patients younger than 40 years and MVD >20 had poorer disease-free interval and survival (P = 0.0029). MVD in patients with squamous cell cervical cancer stage II and age younger than 40 may play a role in predicting recurrence and survival.

Abstract
The objective of this study was to evaluate whether intratumoral blood flow as assessed by transvaginal color Doppler ultrasonography (TVCD) correlates with some tumor features in cervical cancer. Clinical, sonographic, and histologic data on 49 women (mean age: 50.3 years, range: 25-85 years) diagnosed as having a carcinoma from the uterine cervix were reviewed. Intratumoral blood flow was assessed by TVCD in all cases. Subjective impression of the amount of flow (scanty, moderate, or abundant) as well as the lowest resistance index (RI) and highest peak systolic velocity (PSV, cm/s) were used for analysis. These data were correlated with some tumoral features such as histologic type, histologic grade, tumor volume, and tumor stage. Intratumoral blood flow was found in all cases. Abundant blood flow was found more frequently in squamous carcinoma, moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.0001). Significantly lower RI was found in moderately or poorly differentiated tumors and advanced stage tumors (P < 0.01) and significantly higher PSV was found in moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.01). No correlation was found between RI and PSV and histologic type. Our data indicate that intratumoral blood flow as assessed by TVCD correlates well with some tumor features in cervical cancer.

Abstract
Dynamic susceptibility contrast imaging has proven to be useful in brain tumor studies, and it provides additional information on tumor characteristics based on the microvascular structure of gliomas. The cerebral blood volume maps can be used to noninvasively grade gliomas, to determine optimal biopsy sites, to separate radiation necrosis from tumor regrowth, and to plan and follow irradiation, chemo- and antiangiogenic therapy. Besides of cerebral blood volume mapping, dynamic susceptibility contrast imaging sets also contain information about the flow and permeability properties of the tumor microvascular system. When combined with the conventional MRI, dynamic susceptibility contrast techniques offer important functional information about the biology of gliomas in a cost-effective way.

Abstract
PURPOSE To clarify the role of vascular endothelial growth factor (VEGF) expression as an independent prognostic factor in Stage IB cervical cancer. METHODS AND MATERIALS A total of 117 patients with Stage IB cervical cancer who had undergone radical hysterectomy and pelvic lymph node dissection with complete histopathologic examination were included. Eighty-eight (75.2%) patients received postoperative radiotherapy and/or chemotherapy. VEGF expression was examined using immunohistochemistry. RESULTS Of 117 patients, 35 (29.9%) showed high-intensity VEGF expression and 69 (59%) had a high score for area of VEGF expression. Strong correlations were found between high VEGF intensity and both deep stromal invasion (p = 0.01) and positive pelvic lymph nodes (p = 0.03). The area of VEGF expression was significantly associated with tumor size (p = 0.02). In a multivariate analysis, high VEGF intensity (p = 0.009) and tumor size (p = 0.01) were significant prognostic factors for overall survival and disease-free survival (p = 0.001 and p = 0.003, respectively). However, the area of VEGF expression was not a prognostic factor for overall survival or disease-free survival. CONCLUSION Our findings on the correlation between VEGF expression and prognosis were conflicting. Functional and quantitative tools to assess tumor angiogenesis in addition to the expression of VEGF need to be developed and would be helpful to support the finding that tumor angiogenesis correlates significantly with prognosis in early-stage cervical cancer.

Abstract
BACKGROUND Angiogenesis is a crucial step in tumor growth and progression. Its quantification by microvessel counting has a prognostic value in several types of malignancies and recently has been appraised in gastrointestinal tumors. AIM To assess the prognostic significance of microvessel quantification in colorectal carcinomas, studying its association with hematogenous metastases, survival and clinicopathological variables such as size, histologic differentiation and depth of tumoral invasion. PATIENTS/METHODS Forty eight patients with colorectal adenocarcinoma were included in this study. Histologic sections of invasion tumoral margin (4 microns) were analyzed and endothelined microvessels were immunostained with monoclonal mouse Von Willebrand Factor (anti-FVIII). The microvessel count was performed from the identification of the area with increased microvessel density--hot spots--and results of the mean in five of these fields. RESULTS The cut-off microvessel count was 14 microvessels/0.785 mm2, which divided the sample into hypovascular and hypervascular groups. While 2/8 (25%) tumors with muscularis propria invasion were classified as hypervascular, 11/15 (73%) tumors with serosa or perivisceral fat were classified as hypervascular. However, a non-significant statistical association was found between the angiogenesis quantification, hematogenous metastases, survival and clinicopathological variables such as size and histologic differentiation of the tumor. CONCLUSIONS The findings of significantly increase of microvessel count in conformity with tumoral invasion depth supports the hypothesis that tumor progression might be related to angiogenesis. Although angiogenesis is an important step in the tumoral growth and during the metastatization process, other factors can be implicated.

Abstract
Increasing importance is given to the clinical significance of the new formation of vessels (angiogenesis) in the course of physiological inflammatory and neoplastic processes. Angiogenesis is best studied in the growth of malignant tumors, since cancer may be regarded as the most important angiogenesis-dependent disease. Vascular endothelial cell proliferation, migration, and capillary formation are stimulated by angiogenic growth factors, which include the proteins vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and transforming growth factor, and eicosanoids synthesized from n-6 fatty acids. Angiogenesis plays an important role in physiological proliferation of the endometrium and formation of corpus luteum in the second half of menstrual cycle. The present study showed that microvessel counts affect prognosis of patients with endometrial cancer. Analysis of angiogenesis in endometrial cancer may be a useful biologic parameter and additional study of neovascularization is required. Tumor angiogenesis is regulated by the balance of stimulators (e.g., VEGF, bFGF) and inhibitors of angiogenesis (e.g., angiostatin, endostatin, angiostatic steroids). Measuring angiogenesis (blood vessel density) and/or its main regulators such as VEGF and bFGF in solid tumors, or the levels of these growth factors in the serum or urine provides new and sensitive markers for tumor progression, metastasis and prognosis.

Abstract
Tumor angiogenesis is required for tumor growth and metastasis. A statistically significant correlation has been demonstrated between prognosis and the microvessel density (a measure of tumor angiogenesis) of solid tumors, particularly of the breast and prostate, and lymphoid neoplasms. The aim of this study was to establish whether a correlation exists between vascular density and the malignant category of Non-Hodgkin's Lymphoma (NHL) defined by two classification systems (Kiel and Working Formulation). We also tested whether florid follicular hyperplasia (FFH) and follicular lymphomas (FL) behave as new vessel stimulating conditions. Eighty-nine NHL lymph node biopsies were reviewed and categorized according to the Kiel Classification and Working Formulation. Twelve FL were also selected and compared to 12 FFH biopsies. Vessels were highlighted by immunostaining with anti-Factor VIII antibody and quantified both by counting higher vascular density fields and by estimating the proportional vascular area. The results showed a statistically significant difference between low and high grade NHL, when classified in either the Working Formulation (p=0.0015) or the Kiel Classification (p=0.002). No differences were found in vessel counts between Working formulation intermediate and high grade lymphomas. Vascular density is similar when FFH and FL interfollicular areas are compared.

Abstract
PURPOSE A retrospective study was performed to investigate the relationship between spontaneous apoptosis and angiogenesis uterine cervix squamous cell carcinoma patients. The prognostic value of each (and both) of these biologic parameters was also tested. METHODS AND MATERIALS The pathologic materials of 40 cervical uteri squamous cell carcinoma patients were examined and immunohistochemically stained to determine the tumor angiogenesis (tumor microvascular score), using factor VIII-related antigen, and their tumor apoptotic index (AI), using the TdT-mediated dUTP nick end-labeling (TUNEL) method. Three patients were Stage I, 18 were Stage II, 15 were Stage III, and 4 were Stage IV (FIGO classification). All patients were treated with radical radiotherapy and all had follow-up for more than 2 years. RESULTS The mean AI was 15.1 +/- 12.8, with a median of 8.3. The mean tumor microvascular score was 39.7 +/- 14.4, with a median of 3 8. The patients' age and tumor grade did not seem to significantly affect the prognosis. On the other hand, AI and angiogenesis (tumor microvascular score) were of high prognostic significance. The 3-year disease-free survival (DFS) rate for the patients having AI above the median was 78% (confidence interval [CI] 69-87%), compared to 32% (CI 22-42%) for those having AI below the median. The DFS was 18% (CI 9-27%) for patients having an angiogenesis score above the median, while it was 86% (CI 78-94%) for those patients having a score below the median. CONCLUSION Determination of both tumor microvascular score and AI can identify patients with the best prognosis of 100% DFS (with low angiogenesis score and high AI). Women with a high score and low AI had the worst prognosis (DFS = 3%, CI 1-5%). Moreover, high AI can compensate partially for the aggressive behavior of tumors showing a high rate of angiogenesis.

Abstract
OBJECTIVES The aim of this study was to investigate the effectiveness of transvaginal power Doppler angiography in predicting cervical malignancy by detecting intratumoral blood flow and to understand the relationship between squamous cell carcinoma (SCC) serum levels and intratumoral blood flow analysis of invasive cervical carcinoma before treatment. METHODS Thirty-eight patients with cervical carcinoma (35 with stages Ia to IVb invasive carcinoma, 3 with cervical carcinoma in situ) were enrolled for the evaluation of tumor flow using transvaginal ultrasound accompanied with power Doppler angiography before surgery. The pulsatility, resistance index, and vascular index of tumor flow were measured. Thirty patients with proven healthy cervices were used as the control group. Pretreatment SCC serum levels were obtained in 34 women with cervical carcinoma. RESULTS The pulsatility index and resistance index were significantly lower in the study group than in the control group (P < 0.0001). The vascular index was also significantly lower in the study group than in the control group (P < 0.0001). There were no significant differences among patients with SCC type and non-SCC type cervical carcinoma (P > 0.05) among the six parameters. There was no significant correlation between the pretreatment SCC serum levels with any of the six parameters obtained from the intratumoral blood flow analysis in the SCC group. CONCLUSIONS Transvaginal ultrasound with power Doppler angiography is a valuable diagnostic tool for differentiating benign tumors of the cervix from malignant ones. Intratumoral blood flow of the cervix supplied us with practical diagnostic information before surgery and may aid in early prediction and management of cervical carcinoma. The use of transvaginal ultrasound with power Doppler angiography in the grading of vascularity ratio within cervical masses provided more sonographic characteristics among the different subclassifications of cervical cancer and is more useful than color Doppler imaging in the visualization of sonographic morphology.

Abstract
OBJECTIVE Currently, we lack a theoretical explanation for why squamous cell cervical cancer develops predominantly in specific sites (i.e., along the squamocolumnar junction). We therefore implanted human cervical tissues containing the transformation zone in severe combined immunodeficiency (SCID) mice and studied morphology, steroid effects, gene expression, and human papillomavirus (HPV) factors. METHODS Normal and dysplastic human cervical tissues (3 x 2 mm) were placed subcutaneously in SCID-beige mice and later assessed by in situ hybridization for HPV 16/18 DNA and by immunohistochemistry for expression of CD31, keratin, proliferating-cell nuclear antigen, HPV 16 E6, p53, and Notch-1 (a binary cell fate determination protein). Some normal tissues were implanted with either a 90-day release 1.7-mg 17beta-estradiol pellet or a 5-mg tamoxifen pellet; others were infected prior to implantation with human recombinant adenovirus 5 vector containing a human cytomegalovirus promoter-driven beta-galactosidase gene and later assessed by X-gal staining. RESULTS Murine and human vessels formed anastomoses by 3 weeks. For at least 11 weeks, normal tissue retained the transformation zone and normal cell-type-specific keratin expression and exhibited normal proliferation; Notch-1 was present only in the basal cell layer. Dysplastic tissues exhibited koilocytosis, increased levels of cellular proliferation, and aberrant keratin, p53, and Notch-1 expression; HPV 16/18 DNA and HPV 16 E6 protein were detected for at least 6 weeks. Squamous metaplasia of normal cervical epithelium resulted from estrogen exposure, and a predominant columnar differentiation pattern was associated with tamoxifen administration. Through stable adenovirus infection, beta-galactosidase was expressed for at least 6 weeks. CONCLUSIONS This small manipulatable xenograft model maintains normal and dysplastic human cervical epithelium through neovascularization. Neoplastic tissue retains HPV 16/18 DNA and a premalignant phenotype, including elevated levels of cellular proliferation and aberrant keratin, p53, and Notch-1 expression. These attributes constitute essential features of a biologic model through which one may study HPV-mediated human disease and may be superior to cell culture and transgenic murine systems. Furthermore, this may serve as a model for gene therapy. Finally, we suggest that the normal cervical epithelium is maintained through putative interactions between the Notch locus and cell cycle growth regulators such as p53 and pRb. Neoplastic cervical epithelium may arise through disruption of this pathway. This theory may be testable in our animal model.

Abstract
Poor outcome of treatment was found to be associated with low oxygen tension in the primary tumor and not with high intratumor microvessel density in 40 patients with advanced squamous cell carcinoma of the uterine cervix. Multivariate Cox regression analysis identified the total volume of the hypoxic tumor regions, i. e. the tumor subvolume having pO(2) values below 5 mmHg, as a significant prognostic factor for locoregional control, disease-free survival, and overall survival. Other important prognostic factors, identified by univariate Cox regression analysis, were tumor volume, the fraction of pO(2) readings giving pO(2) values below 5 mmHg, and tumor stage.
