Validation of the SNACOR clinical scoring system after transarterial chemoembolisation in patients with hepatocellular carcinoma
2017
Abstract Background Transarterial chemoembolisation is the standard of care for intermediate stage (BCLC B) hepatocellular carcinoma, but it is challenging to decide when to repeat or stop treatment. Here we performed the first external validation of the SNACOR (tumour Size and Number, baseline Alpha-fetoprotein, Child-Pugh and Objective radiological Response) risk prediction model. Methods A total of 1030 patients with hepatocellular carcinoma underwent transarterial chemoembolisation at our tertiary referral centre from January 2000 to December 2016. We determined the following variables that were needed to calculate the SNACOR at baseline: tumour size and number, alpha-fetoprotein level,…
Is sentinel lymph node biopsy more accurate than axillary dissection on staging the nodal involvement in breast cancer patients?
2007
Today evaluation of axillary involvement can be routinely performed with the technique of sentinel lymph node biopsy (SLNB). One of the greatest advantages of SLNB is the nearly total absence of local postoperative complications. It is important to understand whether SLNB is better than axillary lymph-node dissection (ALND) for staging axillary nodal involvement. The aim of the study was to evaluate the axillary staging accuracy comparing three different methods: axillary dissection, sentinel node biopsy with the traditional 4-6 sections and sentinel node biopsy with complete analysis of the lymph node. 527 consecutive patients (525 females and 2 males) with invasive breast cancer < or = 3 …
Impairment of antioxidant enzymes, lipid peroxidation and 8-oxo-2'-deoxyguanosine in advanced epithelial ovarian carcinoma of a Spanish community.
2006
In the present study, we describe the changes of antioxidant enzyme activities and other oxidative stress-related parameters in a mediterranean cohort of women affected with epithelial ovarian carcinoma (EOC). For that purpose, the most representative enzymatic activities, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) and the oxidized/reduced glutathione (GSSG/GSH) ratio have been analyzed in tumor tissue biopsies and compared with the normal tissue of the same patient. As oxidation products, the levels of malondialdehyde (MDA) as an indication of lipid peroxidation, and the DNA damaged base 8-oxo-2'-deoxyguanosine (8-oxo-dG) have been also measured. Ad…
Concordance of Genomic Alterations between Primary and Recurrent Breast Cancer
2014
Abstract There is growing interest in delivering genomically informed cancer therapy. Our aim was to determine the concordance of genomic alterations between primary and recurrent breast cancer. Targeted next-generation sequencing was performed on formalin-fixed paraffin-embedded (FFPE) samples, profiling 3,320 exons of 182 cancer-related genes plus 37 introns from 14 genes often rearranged in cancer. Point mutations, indels, copy-number alterations (CNA), and select rearrangements were assessed in 74 tumors from 43 patients (36 primary and 38 recurrence/metastases). Alterations potentially targetable with established or investigational therapeutics were considered “actionable.” Alterations…
EGFR and PCNA experession in oral squamous cell carcinomas—a valuable tool in estimating the patient's prognosis
1993
We investigated 100 cases of oral squamous cell carcinomas immunohistologically with respect to the expression of the epidermal growth factor receptor (EGFR) and the proliferating cell nuclear antigen (PCNA). The results were correlated with a new malignancy grading of the invasive tumour areas and the clinical outcome of the patients to estimate the individual prognosis. In conclusion, the amount of antigen expression of both antigens increases with the increasing grade of malignancy of the oral squamous cell carcinoma. Furthermore, there is a statistically significant correlation between the amount of antigen expression and the patient's prognosis. An overexpression of EGFR and PCNA is as…
Lack of correlation between expression of HIF-1alpha protein and oxygenation status in identical tissue areas of squamous cell carcinomas of the uter…
2004
Abstract Hypoxia inducible factor-1α (HIF-1α) has been proposed as a candidate endogenous marker of tumor hypoxia and as a molecular mediator of hypoxia-driven malignant progression and acquired treatment resistance. In this study, HIF-1α expression in 68 biopsies of oxygenation measurement tracks from squamous cell carcinomas of the uterine cervix of 38 patients was assessed. Expression of HIF-1α was commonly found to increase as a function of distance from microvessels, at the center of tumor cell aggregations, and in the vicinity of necrotic areas. However, there was no correlation of HIF-1α expression with median oxygen tension (oxygen partial pressure; pO2) and hypoxic fractions (hypox…
Survival of ovarian cancer patients in Germany in the early 21st century: a period analysis by age, histology, laterality, and stage.
2012
Population-based studies on ovarian cancer providing survival estimates by age, histology, laterality, and stage have been sparse. We aimed to derive the most up-to-date and detailed survival estimates for ovarian cancer patients in Germany. We used a pooled German national dataset including data from 11 cancer registries covering 33 million populations. A total of 21 651 patients diagnosed with ovarian cancer in 1997-2006 were included. Period analysis was carried out to calculate the 5-year relative survival (RS) for the years 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age adjustment was performed using five age groups (15-44, 45-5…
Validity of Laparoscopic Staging to Avoid Adjuvant Chemoradiation following Radical Surgery in Patients with Early Cervical Cancer
2012
<b><i>Purpose:</i></b> To determine the rate of unavoidable adjuvant chemoradiation (RCTX) due to histologic results after radical surgery in patients with early cervical cancer. <b><i>Patients and Methods:</i></b> Between May 2004 and July 2011, 448 consecutive patients diagnosed with invasive cervical cancer stage IA1 L1 to IIA underwent laparoscopic staging at the Department of Gynecology and Gynecologic Oncology at Charité Berlin. Only in patients without lymph node metastases (n = 394) on frozen section, radical operation was continued either by laparoscopic radical hysterectomy (n = 228) or by radical vaginal trachelectomy (n = 166). The…
Mobilization of peripheral blood progenitor cells with a combination of cyclophosphamide, r-metHuSCF and filgrastim in patients with breast cancer pr…
2002
The objective of our study was to determine the effect of adding r-metHuSCF to Filgrastim and cyclophosphamide for mobilization of peripheral blood progenitor cells (PBPC), on collection of CD34(+) cells and engraftment after autologous stem cell transplant. Twenty-three patients with previously treated stage II-IV breast cancer received cyclophosphamide (3 g/m(2)), Filgrastim 5 microg/kg daily and r-metHuSCF 20 microg/kg daily. Two PBPC collections were performed on consecutive days starting the day the WBC count was above 7.5 x 10(3)/microl. Collection was performed between days +9 and +12 and the median number of CD34(+) cells collected was 9.9 x 10(6)/kg (1.1-53.1) and 6.6 x 10(6)/kg (1…
Emotional suppression and breast cancer: validation research on the Spanish Adaptation of the Courtauld Emotional Control Scale (CECS).
2010
Emotional suppression has played an important role in the research on psychosocial factors related to cancer. It has been argued to be an important psychological factor predicting worse psychosocial adjustment in people with cancer and it may mediate health outcomes. The reference instrument in the research on emotional suppression is the Courtauld Emotional Control Scale (CECS). The present study analysed construct validity of a new Spanish adaptation of the CECS in a sample of 175 breast cancer patients. The results confirmed the proposal by Watson and Greer claiming that the CECS is composed of three subscales that measure different dimensions, but not independent, from emotional control…
