Congenital absence of the vas deferens (CAVD) is a heterogeneous disorder, largely due to mutations in the cystic fibrosis (CFTR) gene. Patients with unilateral absence of the vas deferens (CUAVD) and patients with CAVD in association with renal agenesis appear to have a different aetiology to those with isolated CAVD. We have studied 134 Spanish CAVD(More)
OBJECTIVE Malnutrition is frequent in cancer. The objective of this study was to determine the prevalence, in Spain, of malnutrition in cancer patients with advanced disease and to assess the therapeutic focus. METHODS A total of 781 patients were evaluated to determine individual nutritional status using the Scored Patient Generated-Subjective Global(More)
BACKGROUND Androgen receptor (AR) gene mutations are the most frequent cause of 46,XY disorders of sex development (DSD) and are associated with a variety of phenotypes, ranging from phenotypic women [complete androgen insensitivity syndrome (CAIS)] to milder degrees of undervirilization (partial form or PAIS) or men with only infertility (mild form or(More)
Although thyroid cancer usually has an excellent prognosis, few therapeutic options are available in the refractory setting. Based on the recent results of phase II studies with tyrosine kinase inhibitors, we designed a retrospective analysis of patients with metastatic thyroid cancer treated with sorafenib in seven Spanish referral centers. Consecutive(More)
BACKGROUND Refractory or relapsing Hodgkin's disease is associated with a poor prognosis. There is no widely accepted salvage chemotherapy regimen for these patients. However, the addition of high-dose chemotherapy followed by autologous hematopoietic transplantation (AHT) has proven of benefit to them. A prospective clinical trial was carried out to(More)
Germline mutations in DNA polymerase ɛ (POLE) and δ (POLD1) have been recently identified in families with multiple colorectal adenomas and colorectal cancer (CRC). All reported cases carried POLE c.1270C>G (p.Leu424Val) or POLD1 c.1433G>A (p.Ser478Asn) mutations. Due to the scarcity of cases reported so far, an accurate clinical phenotype has not been(More)
Since the introduction of multimodality treatment, the prognosis of patients with high-grade non-metastatic osteosarcoma has significantly improved. A retrospective review was performed to assess the long-term results of this approach in a single centre setting, and to investigate the impact of potential clinical prognostic factors. Between 1985 and 1993,(More)
Colorectal cancer (CRC) is one of the most common malignant tumors in adults. Twenty-five percent of patients are not amenable to surgical resection because they have locally advanced or metastatic disease. For these patients, median survival time is between 4 and 13 months, and chemotherapy is used mainly with palliative intent. We conducted this study to(More)
Neoadjuvant chemotherapy (CT), prior to radical radiotherapy (RT), in the treatment of high-grade gliomas may offer several advantages over standard adjuvant CT. The addition of tamoxifen, which can circumvent P-glycoprotein (P-gp)-mediated chemo-resistance, also merits attention. We have evaluated the neoadjuvant regimen of cisplatin and etoposide after(More)
