Prognostic Potential Of The Pretherapeutic Tumor Oxygenation Status
2009
Hypoxia, a characteristic feature of locally advanced solid tumors, has emerged as a key factor of the tumor pathophysiome, since it can promote tumor progression and resistance to therapy. Independent of established prognostic parameters, such as clinical tumor stage, histology, histological grade and nodal status, hypoxia has been identified as an adverse prognostic factor for patient outcome. Studies of pretreatment tumor hypoxia involving direct assessment (polarographic oxygen tension measurements) have suggested a poor prognosis for patients with hypoxic tumors. These investigations indicate a worse disease-free survival for patients with hypoxic cancers of the uterine cervix or soft …
Human papillomavirus genotype attribution in invasive cervical cancer: a retrospective cross-sectional worldwide study.
2010
Summary Background Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. Methods Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and informa…
Detection and characterization of tumor hypoxia using pO2 histography.
2007
Data from 125 studies describing the pretreatment oxygenation status as measured in the clinical setting using the computerized Eppendorf pO2 histography system have been compiled in this article. Tumor oxygenation is heterogeneous and severely compromised as compared to normal tissue. Hypoxia results from inadequate perfusion and diffusion within tumors and from a reduced O2 transport capacity in anemic patients. The development of tumor hypoxia is independent of a series of relevant tumor characteristics (e.g., clinical size, stage, histology, and grade) and various patient demographics. Overall median pO2 in cancers of the uterine cervix, head and neck, and breast is 10 mm Hg with the ov…
Comparison of the combined action of oxaliplatin or cisplatin and radiation in cervical and lung cancer cells
2007
To test the combined effects of oxaliplatin and radiation versus cisplatin and radiation using human cervical and lung cancer cell lines.CaSki cervical cancer cells, and A549 lung cancer cells were cultured under standard conditions. Cells were treated with escalating doses of gamma-irradiation (0-6 Gy), and with oxali- and cisplatin for 2 h or 24 h, or a combination of both. Cell survival was measured by a colony-forming assay. Survival curves were fitted to the data using the linear quadratic model. Sensitizer enhancement ratios (SER) were calculated at the 37% survival level, and isobologram analysis was applied to test for the drug-radiation interactions.Oxaliplatin as well as cisplatin…
Survival after curative pelvic exenteration for primary or recurrent cervical cancer a retrospective multicentric study of 167 patients
2014
ObjectiveEvaluate the survival of patients who underwent pelvic exenteration (PE) with curative intent for primary persistent or recurrent cervical cancer.MethodsWe retrospectively investigated 167 consecutive patients, referred to the gynecological oncology units of 4 centers in Germany or Italy, who underwent PE. Data regarding surgery, histology, and oncologic outcomes were collected and statistically evaluated. Survival was determined from the day of exenteration until last follow-up or death.ResultsThe median age was 51 years. Twenty-seven patients (16.2%) underwent PE owing to advanced primary tumors (group A), 34 patients (20.4%) underwent PE owing to persistent cancer after chemothe…

Role of robotic surgery in ovarian malignancy
2017
As part of minimally invasive surgery, robotic-assisted approach is becoming increasingly popular in gynecologic oncology. It has been shown to be effective and feasible for staging and treating endometrial and cervical cancer, but its role in the context of primary and recurrent ovarian cancers is presently debated. Scanty data are available in the literature, and the level of evidence supporting its use in ovarian cancer is quite low. However, from a retrospective case-control series, robotic surgery seems to be safe and feasible for early-stage ovarian cancer. Its use in treating patients with advanced-stage or relapsed ovarian cancer is still highly controversial, suggesting the choice …
Retrospective Data Analysis of Anterior Cervical Discectomies and Fusion Without Plate and Screws
2019
Abstract Surgical intervention in cervical disease can relieve neurological symptoms and improve life quality. This study aimed to analyse retrospective data of microscope-assisted anterior cervical discectomy and fusion (ACDF) surgeries. The retrospective study was carried out at the ORTO clinic, Rīga, Latvia, from 2013 to 2017. Data from 198 patients were extracted retrospectively. Data on patient gender, age, diagnosis, extent of operation, type of cage and the overall height of the implants were used. Comparative analysis was carried out with the SPSS 22 software. P < 0.05 represented statistical significance. During the study period, 198 elective ACDF were carried out with increasin…
Management of Odontoid Cervical Fracture
2019
Fractures of the cervical odontoid process are the most common fractures of the cervical tract, accounting for one third of all cervical spine fractures. They are more frequent in elderly patients, and with the aging of the world population, their incidence and clinical and social relevance are expected to increase in the near future. The mechanisms underlying odontoid fractures differ according to patient age, with high-energy mechanisms being the causative factor frequently encountered in younger patients and low-energy trauma commonly occurring in elderly patients. Despite rising incidence and costs, there is considerable uncertainty regarding the optimal management for these fractures, …
Cervical vertebral maturation and its relationship to circum-pubertal phases of the dentition in a cohort of Portuguese individuals
2019
Background To explore the relationship between individual skeletal maturity as assessed by Cervical Vertebral Maturity method (CVM), circum-pubertal phases of the dentition (early mixed, intermediate mixed, late mixed and early permanent) and chronlogical age in a cohort of Portuguese individuals. Material and Methods This was a retrospective cross-sectional study. The sample comprised 300 Caucasian Portuguese subjects aged 6 to 16 years, (137 boys and 163 girls). All the participants had good quality panoramic and lateral cephalometric radiographs. Subject skeletal maturity was evaluated using the CVM method. Dental age evaluation was determined by using panoramic radiographs and dental ca…
