Lack of Hypoxic Response in Uterine Leiomyomas despite Severe Tissue Hypoxia
2008
Abstract Hypoxia is now established as a key factor influencing the pathophysiology of malignant growth. Among other effects, hypoxia modulates the expression of a multitude of genes through the induction of hypoxia-inducible transcription factors. This differential gene expression favors angiogenesis, cell survival, an invasive/metastatic phenotype, and resistance to anticancer therapies. Because benign tumors do not exhibit these traits, one might expect these entities to be neither hypoxic nor to induce the genetic hypoxia response program. To test this hypothesis, an investigation of the oxygenation status of 17 leiomyomas and 1 leiomyosarcoma of the uterus using polarographic needle el…
The physician-patient relationship before cancer treatment: a prospective longitudinal study.
2003
Abstract Objectives . To evaluate quality of life before surgery for genital cancer to determine risk factors that might influence the physician–patient relationship. Methods . From 1993 until 2003, 129 women with cervical cancer entered this prospective study. Patients were contacted 1 to 5 days before surgery by a psychologist or psychotherapeutically trained physician on the surgical ward. The semistructured interview included questions on the patient's psychosocial well-being according to criteria of the biographic interview technique. The preoperative anxiety level was evaluated by the STAI and quality of life by the Cancer Rehabilitation Evaluation System (CARES) and EORTC questionnai…
Prevalence of antibodies to human papillomaviruses in the general population of the Czech Republic.
1998
Sera from 450 individuals between the age of 1 and 80 years, representing the general population of the Czech Republic, were tested for the presence of antibodies to human-papillomavirus(HPV)-derived antigens. The following antigens were used: (i) HPV1 virions; (ii) HPV16, -18 and -33-virus-like particles (VLP); (iii) peptides derived from L2 open reading frames (ORFs) of HPV16 and HPV6/11; (iv) peptides derived from HPV16 E2, E4 and E7 ORFs of HPV16. The prevalence of antibodies reactive with the capsid-derived antigens was age-dependent, while no clear age dependence was observed in the distribution of antibodies to peptides derived from HPV16 early proteins. In individual sera, high corr…

Local anesthetic switching for intrathecal tachyphylaxis in cancer patients with pain.
2003
IMPLICATIONS Switching from bupivacaine to lidocaine may improve intrathecal morphine analgesia in advanced cancer patients, possibly because of different spinal mechanisms limiting the hyperalgesic processes.
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 …
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…
