Objective: To analyse the radiological outcomes in the long term of unstable thoraco-lumbar fractures. Material and methods: Retrospective review of 100 patients with unstable thoracolumbar fractures treated with posterolateral fusion and short screw fixation for compression and flexion-distraction type fractures, and long segment posterior fixation for fractures-dislocations or more than one vertebra fractured, between 2000 and 2010 at three different hospital centers. Six radiological parameters were measured annually during a 4-year period: Fracture angle, kyphotic deformity, sagittal index, percentage of compression, degree of displacement and deformation angle. Results: A total of 100 patients were included with a median age of 36,4 years and a median follow-up period of 7.2 years. Fracture angle rose from 11,6° to 14,5° (increase of 25%), kyphotic deformity from 14,5° to 16,7° (increase of 15,17%), sagittal index from 8,7 to 10,8 (increase of 24,13%), percentage of compression from 31,8% to 36,5% (increase of 6,88%), degree of displacement from 2,8. mm to 4,6. mm (increase of 14,77%) and deformation angle from 19.7° to 21.4° (increase of 8,62%). Discussion: All the radiological parameters studied lost correction throughout the 48 months of follow-up, being the fracture angle the most affected one. Nevertheless, the greatest loss of correction occurs in the first postoperative year, stabilizing the parameters afterwards over the 4 years of follow up. We routinely recommend the measurement of all previous parameters for the follow up of unstable thoracolumbar fractures. © 2017 Sociedad Española de Neurocirugía.

Nowadays and given the improvement in response rate with the new schemes of treatment with chemotherapy, the interest in neoadjuvant treatment for pancreatic ductal adenocarcinoma, allowing the early application of systemic therapies, has also increased. However, treatment selection fundamentally depends on decisions taken by multidisciplinary committees due to the absence of randomized trials on this indication and because the available evidence is based primarily on small studies. The present manuscript tries to establish recommendations based on the available evidence and expert opinion to correctly select the indication, the type of treatment, as well as its duration and how to correctly follow-up patients during treatment with chemotherapy. © 2017 Federación de Sociedades Españolas de Oncología (FESEO)

Objective: To determinate the impact of maximal cytoreductive surgery on progression free survival (PFS), overall survival (OS) rates and morbidity, in patients with advanced epithelial ovarian or fallopian tube cancer. Methods: We reviewed all medical records of patients with stages IIIC-IV epithelial ovarian and fallopian tube cancer that were managed at our institution between January 2001 and December 2008. The following information was collected: demographics, tumor characteristics, operative information, surgical outcomes and peri-operative complication. Results: A total of 288 patients with advanced epithelial ovarian and fallopian tube cancer were referred to our institution between January 2001 and December 2008, 259 consecutive patients were enrolled in the study. After a median follow-up of 29.8 months, the PFS and OS were 19.9 and 57.6 months, respectively. At univariate analysis, factors significantly associated with decreased PFS included: age greater than median (> 60 years), stage IV, presence of ascites > 1000 cc, presence of diffuse peritoneal carcinomatosis and diameter of residual disease. This was confirmed also at multivariate analysis with age greater than 60 years (P = 0.025), stage IV vs IIIC (P = 0.037) and any residual disease (P = 0.032) having an independent association with worse PFS. Conclusions: Our study seems to demonstrate that a more extensive surgical approach is associated with prolonged disease-free interval and improved survival in patients with stages IIIC-IV epithelial ovarian and fallopian tube cancer. Moreover all patients with no residual tumor seem to have the best prognosis and in view of these results we believe that the goal of primary surgery should be considered as leaving no macroscopic disease. © 2010 Elsevier Inc.

Objective: Systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are related chronic autoimmune diseases of complex aetiology in which the interferon (IFN) pathway plays a key role. Recent studies have reported an association between IRF7 and SLE which confers a risk to autoantibody production. A study was undertaken to investigate whether the IRF7 genomic region is also involved in susceptibility to SSc and the main clinical features. Methods: Two case-control sets of Caucasian origin from the USA and Spain, comprising a total of 2316 cases of SSc and 2347 healthy controls, were included in the study. Five single nucleotide polymorphisms (SNPs) in the PHRF1-IRF7-CDHR5 locus were genotyped using TaqMan allelic discrimination technology. A meta-analysis was performed to test the overall effect of these genetic variants on SSc. Results: Four out of five analysed SNPs were significantly associated with the presence of anticentromere autoantibodies (ACA) in the patients with SSc in the combined analysis (rs1131665: p FDR=6.14 × 10 -4, OR=0.78; rs4963128: p FDR=6.14 × 10 -4, OR=0.79; rs702966: p FDR=3.83 × 10 -3, OR=0.82; and rs2246614: p FDR=3.83 × 10 -3, OR=0.83). Significant p values were also obtained when the disease was tested globally; however, the statistical significance was lost when the ACA-positive patients were excluded from the study, suggesting that these associations rely on ACA positivity. Conditional logistic regression and allelic combination analyses suggested that the functional IRF7 SNP rs1131665 is the most likely causal variant. Conclusions: The results show that variation in the IRF7 genomic region is associated with the presence of ACA in patients with SSc, supporting other evidence that this locus represents a common risk factor for autoantibody production in autoimmune diseases.

Background: To test the efficacy of levonorgestrel-release intrauterine device (LNG-IUD) plus gonadotropin-releasing hormone (GnRH) for treating women aged <40 years with atypical endometrial hyperplasia (AEH) or presumed International Federation of Gynecology and Obstetrics stage IA limited to the endometrium, well differentiated (G1), endometrioid endometrial cancer (EC), who wish to preserve their fertility. Patients and methods: A prospective observational study was conducted. Treatment consisted on the insertion of an LNG-IUD for 1 year plus GnRH analogue for 6 months. Results: From January 1996 to June 2009, 20 and 14 patients with AEH and EC, respectively, were studied. Complete response rate was 95% in patients with AEH and 57.1% in women with EC-G1. A progression of the disease was observed in one (5%) and in four patients (28%) with AEH and EC, respectively. Four of 20 patients with AEH and 2 of 14 with EC-G1 experienced recurrences. The average relapse time was 36 months (range: 16-62 months). All of them were alive without evidence of disease at the last follow-up, mean: 29 months (range: 4-102 months). Nine women achieved 11 spontaneous pregnancies. Conclusions: The combined treatment showed effectiveness in a substantial proportion of patients with AEH and EC. Close follow-up during and after treatment is crucial. © The Author 2010. Published by Oxford University Press on behalf of the European Society for Medical Oncology. All rights reserved.

Background: KRAS mutation testing is required to select patients with metastatic colorectal cancer (CRC) to receive anti-epidermal growth factor receptor antibodies, but the optimal KRAS mutation test method is uncertain. Methods: We conducted a two-site comparison of two commercial KRAS mutation kits-the cobas KRAS Mutation Test and the Qiagen therascreen KRAS Kit-and Sanger sequencing. A panel of 120 CRC specimens was tested with all three methods. The agreement between the cobas test and each of the other methods was assessed. Specimens with discordant results were subjected to quantitative massively parallel pyrosequencing (MPP). DNA blends were tested to determine detection rates at 5% mutant alleles. Results: Reproducibility of the cobas test between sites was 98%. Six mutations were detected by cobas that were not detected by Sanger, and five were confirmed by MPP. The cobas test detected eight mutations which were not detected by the therascreen test, and seven were confirmed by MPP. Detection rates with 5% mutant DNA blends were 100% for the cobas and therascreen tests and 19% for Sanger. Conclusion: The cobas test was reproducible between sites, and detected several mutations that were not detected by the therascreen test or Sanger. Sanger sequencing had poor sensitivity for low levels of mutation. © 2012 Cancer Research UK All rights reserved.

Objective: To address if prostate cancer (PCa) screening decreases PCa mortality in the asymptomatic population, within the setting of the Spanish arm of the European Randomized Study of Screening for Prostate Cancer (ERSPC). Material and methods: From 1996 to 1999, 4,278 men aged 45-70 years were recruited and randomized to the screening arm (PSA every 4 years, prostate biopsy when PSA ≥ 3 ng/ml) and control arm (no tests). Dates and causes of death were collected on an annual basis. A Kaplan-Meier analysis was used to calculate overall and cancer-specific survival. Results: A total of 2,416 men were recruited in the screening arm and 1,862 in the control arm. Mean age was 57.8 years, median follow-up was 13.3 years. At the end of the follow-up period, 427 deaths (9 from PCa) were observed. Survival analysis did not show any difference between the study arms with respect to overall and cancer-specific survival (p = 0.939 and p = 0.544 respectively). Most relevant causes of death were malignant tumors (52.9%), cardiovascular disease (17.3%) and respiratory (8.9%). Only 2.1% of deaths (0.2% of all recruited men) were due to PCa (2.5% screening, 1.6% control). Conclusions: The Spanish arm of ERSPC failed to reproduce the long-term results shown in the whole study. No differences in mortality (overall or cancer-specific) were observed after 15 years of follow-up. PCa mortality was infrequent (less than 1%). These results suggest limited yield of PCa screening in our setting. © 2011 AEU. Publicado por Elsevier España, S.L. Todos los derechos reservados.

The serum cancer antigen 125 (CA-125) remains a reliable biomarker in the therapeutic management of epithelial ovarian cancer (EOC). Monitoring the effi cacy of cytotoxic chemotherapy (CT) and the early detection of relapse during the follow up of patients in remission represent the two most common clinical situations where the CA-125 has been successfully applied. There are however other scenarios along the course of the disease where the CA-125 can potentially aid in the decision-making process. Preoperative levels of CA-125 can help in selecting a subset of patients where an optimal cytoreduction may not be easily achieved. Perioperative variations in the CA-125 levels after primary surgery and, more importantly, the nadir value of the CA-125 after primary chemotherapy, are associated with patient outcome. This review focuses on the clinical relevance of dynamic changes in CA-125 levels during the primary treatment of EOC and its potential infl uence both in the patient management and in the design of clinical trials in the adjuvant setting.

Platinum-based chemotherapy constitutes the mainstay systemic treatment for patients with epithelial ovarian cancer (EOC). Significant and durable clinical responses are achieved when platinum is administered along with taxanes after debulking surgery, but relapses are common in advanced disease within 2 years upon completion of primary therapy. Furthermore, between 20% and 30% of patients will never respond or will progress shortly after finishing the platinum-containing regimen. To avoid unnecessary toxicities, ideally physicians should be capable of selecting which patients might benefit the most from a particular treatment based on established, predictive factors. Although the cytotoxicity of cisplatin is well described, the mechanisms of platinum resistance developed by tumoral cells are not so well understood. Changes in the DNA repair pathways in tumors possibly have an important role in the development of its platinum-resistant phenotype. Recent advances in this area have identified potential biomarkers (eg, ERCC1 mRNA and protein expression and BRCA mutational status) that may correlate with the clinical efficacy of a platinum-based chemotherapy. Clinical studies that evaluate its potential application in the management of patients with ovarian cancer are now emerging. Future validation of these predictive biomarkers of response to platinum, as well as to other chemotherapeutic agents (eg, taxanes), might set the stage for a more biology-based and rational therapeutic approach to advanced EOC. We review the most recent advances in translational research regarding the DNA repair pathways as a potential source for describing and validating biomarkers of response to platinum agents in ovarian cancer.

Breast Cancer Research and Treatment | Year: 2015

Breast cancer patients suffer impairment in cardiorespiratory fitness after treatment for primary disease, affecting patients’ health and survival. The aim of this study was to evaluate the ability of a pragmatic exercise intervention to improve cardiorespiratory fitness of breast cancer patients after primary treatment. Between February 2013 and December 2014, 94 women with early stage (I–III) breast cancer, 1–36 months post-chemotherapy, and radiotherapy were randomly assigned to an intervention program (EX) combining supervised aerobic and resistance exercise (n = 44) or usual care (CON) (n = 45) for 12 weeks. Primary study endpoint was VO2max. Secondary endpoints were muscle strength, shoulder range of motion, body composition, and quality of life (QoL). Assessments were undertaken at baseline, 12-week, and 6-month follow-ups. Eighty-nine patients aged 29–69 years were assessed at baseline and 12 weeks. The EX group showed significant improvements in VO2max, muscle strength, percent fat, and lean mass (p ≤ 0.001 in all cases) and QoL compared with usual care (CON). Apart from body composition, improvements were maintained for the EX at 6-month follow-up. There were no adverse events during the testing or exercise intervention program. A combined exercise intervention produced considerable improvement in cardiorespiratory fitness, physical function, and quality of life in breast cancer patients previously treated with chemotherapy and radiation therapy. Importantly, most of these benefits were maintained 6 months after ceasing the supervised exercise intervention. © 2015, Springer Science+Business Media New York.
