Treatment patterns for metastatic colorectal cancer in Spain

2020

Abstract Purpose The primary aim of this retrospective study was to describe the treatment patterns according to the type of treatment received by patients with metastatic colorectal cancer (mCRC) in Spain. Methods This was a retrospective, observational, multicenter study performed by 33 sites throughout Spain that included consecutive patients aged 18 years or older who had received or were receiving treatment for mCRC. Results At the time of inclusion, of the 873 evaluable patients, 507 (58%) had received two lines, 235 (27%) had received three lines, 106 (12%) had received four lines, and the remaining patients had received up to ten lines. The most frequent chemotherapy schemes were th…

Predictive and prognostic value of magnesium serum level in FOLFIRI plus cetuximab or bevacizumab treated patients with stage IV colorectal cancer: r…

2020

Magnesium wasting is a frequent side effect of epidermal growth factor receptor (EGFR)-antibody treatment as magnesium-absorption mechanisms are dependent on EGFR signaling. EGFR-inhibition results in decreased renal reabsorption. There is evidence that hypomagnesemia during cetuximab treatment correlates with response. The prognostic role of hypomagnesemia during bevacizumab treatment has not been studied yet. Here, we evaluate the prognostic value of hypomagnesemia in patients with metastatic colorectal cancer treated with FOLFIRI plus cetuximab or bevacizumab as first-line therapy. A total of 391 of 752 patients of the firstline irinotecan study population had magnesium levels measured a…

Outcome of melanoma patients with elevated LDH treated with first-line targeted therapy or PD-1-based immune checkpoint inhibition.

2020

Abstract Background Elevated lactate dehydrogenase (LDH) is a known predictive and prognostic factor for a poor outcome in patients with metastatic melanoma. It is unclear whether first-line targeted therapy (TT) or immune checkpoint inhibition (ICI) is more beneficial in melanoma patients with elevated LDH because prospective studies in this area are lacking. Methods This multicentre retrospective cohort study was conducted at 25 melanoma centres worldwide to analyse progression-free survival (PFS) and overall survival (OS) among melanoma patients with elevated LDH. The role of confounders was addressed by using inverse probability of treatment weighting. Results Among 173 BRAFV600-mutant …

Intratumoral immunosuppression profiles in 11q-deleted neuroblastomas provide new potential therapeutic targets

2021

In this issue, Coronado et al. attempt to improve our understanding of the factors affecting the response to immunotherapy in a large subset of high‐risk neuroblastoma with hemizygous deletion of chromosome 11q. By using several computational approaches, the authors study potential transcriptional and post‐transcriptional pathways that may affect the response to immunotherapy and further be leveraged therapeutically in a biomarker‐directed fashion.

Retrospective study of small pet tumors treated with Artemisia annua and iron.

2019

Artemisinin from Artemisia annua L. and its derivatives are well‑known antimalarial drugs. In addition, in vitro studies, in vivo studies and clinical trials have demonstrated that these drugs exhibit anticancer activity in human patients with cancer. Therefore, the aim of the present study was to investigate whether a phytotherapeutic A. annua preparation exerts anticancer activity in veterinary tumors of small pets. Dogs and cats with spontaneous cancer (n=20) were treated with standard therapy plus a commercial A. annua preparation (Luparte®) and compared with a control group treated with standard therapy alone (n=11). Immunohistochemical analyses were performed with formalin‑fixed paraf…

Correlation between the visibility of submandibular fossa and mandibular canal cortication on panoramic radiographs and submandibular fossa depth on …

2017

Background To identify a correlation between the submandibular fossa (SF) visibility and mandibular canal (MC) cortication on panoramic image and the depth of SF measured on CBCT and also correlation between the depth of SF and vertical and horizontal location of MC on CBCT. Material and Methods 500 CBCT scans and panoramic radiographs were evaluated. SF depth types were classified as type I ( 3mm) on CBCT. Visibility of SF and the cortication of MC on panoramic radiographs were compared with the depth of SF on CBCT. Distances between MC and mandibular inferior, buccal and lingual cortices were measured. Results No statistically significant correlation was found between radiolucent appearan…

Distribution and genotype-phenotype correlation of GDAP1 mutations in Spain

2017

AbstractMutations in the GDAP1 gene can cause Charcot-Marie-Tooth disease. These mutations are quite rare in most Western countries but not so in certain regions of Spain or other Mediterranean countries. This cross-sectional retrospective multicenter study analyzed the clinical and genetic characteristics of patients with GDAP1 mutations across Spain. 99 patients were identified, which were distributed across most of Spain, but especially in the Northwest and Mediterranean regions. The most common genotypes were p.R120W (in 81% of patients with autosomal dominant inheritance) and p.Q163X (in 73% of autosomal recessive patients). Patients with recessively inherited mutations had a more seve…

A Predictive Model of the Prevalence of Delirium in Elderly Subjects Admitted to Nursing Homes.

2017

INTRODUCTION Delirium is common in geriatric patients admitted to nursing homes, with an incidence of 22-79% among long-term residents. AIM To establish a predictive model of the risk of delirium episodes in a sample of elderly people living in nursing homes. MATERIAL AND METHODS A retrospective, cross-sectional case-control study covering a period of 12 consecutive months (April 2014 - March 2015) was carried out. The included cases had suffered at least one episode of delirium during the study period. Sociodemographic and clinical variables as well as risk factors predisposing to or triggering episodes of delirium were recorded. RESULTS A total of 193 cases and 123 controls were recruited…

Is laterality of congenital diaphragmatic hernia a reliable prognostic factor? French national cohort study.

2020

International audience; Objectives: The objective of this study was to assess whether the laterality of congenital diaphragmatic hernia (CDH) was a prognostic factor for neonatal survival.Methods : This was a cohort study using the French national database of the Reference Center for Diaphragmatic Hernias. The principal endpoint was survival after hospitalization in intensive care.We made a comparative study between right CDH and left CDH by univariate and multivariate analysis. Terminations and stillbirths were excluded from analyses of neonatal outcomes.Results: A total of 506 CDH were included with 67 (13%) right CDH and 439 left CDH (87%). Rate of survival was 49% for right CDH and 74% …
