Clinical and radiological features of hybrid surgery in multilevel cervical degenerative disc disease.
2015
Purpose: Although several studies have established the safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF), few studies have investigated the role of hybrid surgery (HS) that incorporates ACDF and CDA techniques in multilevel cervical degenerative disc disease (MLCDDD). Methods: This prospective study enrolled patients with MLCDDD who underwent HS. Twenty consecutive patients who underwent HS were compared with patients who underwent ACDF and CDA at the same level of surgery. Patients were followed up for more than 2 years. Intraoperative parameters, clinical features and outcome scores were recorded. Radiological assessments…
Association of vascular risk factors with cervical artery dissection and ischemic stroke in young adults.
2011
Background— Little is known about the risk factors for cervical artery dissection (CEAD), a major cause of ischemic stroke (IS) in young adults. Hypertension, diabetes mellitus, smoking, hypercholesterolemia, and obesity are important risk factors for IS. However, their specific role in CEAD is poorly investigated. Our aim was to compare the prevalence of vascular risk factors in CEAD patients versus referents and patients who suffered an IS of a cause other than CEAD (non-CEAD IS) in the multicenter Cervical Artery Dissection and Ischemic Stroke Patients (CADISP) study. Methods and Results— The study sample comprised 690 CEAD patients (mean age, 44.2±9.9 years; 43.9% women), 556 patients …
Human papillomavirus antibody responses among patients with incident cervical carcinoma
1997
The human papillomavirus (HPV) is recognized as a major cause of cervical cancer precursor lesions. HPV serology is a key method in the continuing elucidation of the importance of HPV exposure for cancer development and in predicting HPV-associated diseases. To extend previous HPV serological studies on cervical cancer, serum samples from a consecutive series of 216 women with incident untreated cervical carcinoma and 243 age- and sex-matched healthy blood donors were evaluated for the presence of antibodies against HPV capsids, a marker of past or present HPV exposure, as well as against several cervical cancer-associated defined HPV epitopes. Among the capsid antibody responses, HPV type …
Validation of tumour-free distance as novel prognostic marker in early-stage cervical cancer: a retrospective, single-centre, cohort study
2021
Background: The aim of the present study was to assess the prognostic value of tumour-free distance (TFD), defined as the minimum distance of uninvolved stroma between the tumour and peri-cervical stromal ring, in early-stage cervical cancer. Methods: Patients with pathologic FIGO 2009 stage IA1–IIA2 cervical cancer, treated by primary radical surgical treatment between 01/2000 and 11/2019, were retrospectively included. Adjuvant treatment was administered according to the presence of previously established pathologic risk factors. TFD was measured histologically on the hysterectomy specimen. Pre-operative TFD measured at MRI-scan from a cohort of patients was reviewed and compared with pat…
Vinorelbine and Cisplatin for the Treatment of Recurrent and/or Metastatic Carcinoma of the Uterine Cervix
2002
<i>Background:</i> To test the clinical activity and toxicity profile of the combination regimen of vinorelbine and cisplatin in a series of patients with carcinoma of the cervix uteri with de novo metastatic disease or recurrent disease after previous therapy. The main aims of the study included analysis of objective response rates, toxicity, and time to progression. <i>Patients and Methods:</i> Forty-two eligible patients were enrolled into the trial and treated with cisplatin 80 mg/m<sup>2</sup> on day 1 and vinorelbine 25 mg/m<sup>2</sup> on day 1 and 8. This regimen was repeated every 21 days upon resolution of toxicity for 3 cycles befor…
Telomere length in leukocytes and cervical smears of women with high-risk human papillomavirus (HR HPV) infection
2019
Objective: Persistent high-risk HPV (HR HPV) infection leads to the development of squamous intraepithelial lesions, which in turn may progress to cervical cancer. Telomere elongation or shortening may indicate a carcinogenesis process. In the present study, we analyzed telomere length from blood and cervical smears of women without and with high-risk HPV infection. Materials and methods: Telomere length was quantified by real-time PCR in blood and cervical smears from 48 women with high-risk HPV infection and HGSIL or LGSIL, 29 women HR-HPV positive without SIL, and 11 HPV-negative women. Results: No correlation was found between age and telomere length in blood and cervical smears. Women …
Characterization of subcolumnar reserve cells and other epithelia of human uterine cervix. Demonstration of diverse cytokeratin polypeptides in reser…
1987
We have analyzed the expression of cytokeratin polypeptides in subcolumnar reserve cells of the human uterine endocervical mucosa and the other epithelial cells using immunoperoxidase and immunofluorescence microscopy as well as by applying two-dimensional gel electrophoresis to microdissected cytoskeletal preparations. Endocervical columnar cells were uniformly positive for antibodies directed against the simple epithelium-type cytokeratins nos. 7, 8, 18, and 19, while a variable proportion of these cells was stained by an antibody against cytokeratin no. 4. Reserve cells were not only positive for cytokeratins nos. 8 (weakly and variably) and 19 but were also decorated by antibody KA 1, w…
Immunohistochemical localization of filaggrin in benign, premalignant and malignant cervical tissue.
1994
Epithelial distribution of filaggrin, a histidine-rich protein related to squamous terminal differentiation, was investigated in 87 cervical biopsies using an avidin-biotin-peroxidase technique with a monoclonal anti-human filaggrin antibody (AKH1). Normal squamous cervical epithelium exhibited a positive homogeneous immunoperoxidase stain in the upper parabasal, intermediate and superficial cell layers. Similar findings were obtained in cervical condylomas, although full-thickness staining was observed in 35.7% of the cases (P < 0.001). Filaggrin expression in CIN was inversely related to the severity of the lesion (P < 0.001). An irregular staining pattern was present in most high-grade C…
Abnormal Immunoexpression of Cell Adhesion Molecules (CAMs) in Cervical Cancer
2010
Artículo publicado en: International Journal of Surgical Pathology published online 18 July 2010 The purpose of this study was to examine the immunoexpression of cell adhesion molecules (CAMs) E-cadherin, CD44s, and CD44v3 in cervical cancer and compare it with that in benign exo-endocervical tissue. In all, 81 cervical cancer biopsy specimens and 22 benign controls were included. Primary monoclonal antibodies NHC-38, F10-44-2, and 3G5 for E-cadherin, CD44s, and CD44v3 were used, respectively. Statistical significance was evaluated by the ?2 test. Antigen expression was significantly different in cervical cancer specimens compared with controls, showing marked decrease in membrane expressio…
Tumor oxygenation: a new predictive parameter in locally advanced cancer of the uterine cervix.
1993
Abstract Experimental evidence suggests that hypoxia may increase the malignant potential and reduce the sensitivity toward nonsurgical treatment modalities in solid rodent tumors. However, the importance of tumor hypoxia in human malignancies is still uncertain. We have developed a clinically applicable standardized procedure for the determination of intratumoral p O 2 in advanced cervical cancers by use of a computerized polarographic needle electrode histograph. To evaluate the significance of tumor oxygenation as a new oncologic parameter we initiated an open prospective clinical trial at the University of Mainz Medical Center in June 1989. Until October 1992 50 patients with advanced c…
