简介:AbstractImportance:Neuroblastoma is the most common extracranial malignant solid tumor in children. Multidisciplinary care is critical to improving the survival of pediatric patients with neuroblastoma.Objective:To systematically summarize the clinical characteristics of children with neuroblastoma and evaluate their prognosis with multidisciplinary care provided in a single center.Methods:This retrospective study analyzed the clinical data of 1041 patients with neuroblastoma who were diagnosed, treated, and followed-up in the Hematology-Oncology Center of Beijing Children’s Hospital from 2007 to 2019.Results:The median age at diagnosis was 34 months; 80.8% of the patients were younger than 5 years of age. Notably, 243 patients (23.3%) were classified as low-risk, 249 patients (23.9%) were classified as intermediate-risk, and 549 (52.7%) were classified as high-risk. Furthermore, 956 patients underwent surgical resections; 986 (94.7%) patients received chemotherapy; and 176 patients with high-risk neuroblastoma received hematopoietic stem cell transplantation. The 5-year event-free survival (EFS) rate was 91.3% and 5-year overall survival (OS) rate was 97.5% in low-risk group; in the intermediate-risk group, these rates were 85.1% and 96.7%, respectively, while they were 37.7% and 48.9% in the high-risk group (P < 0.001 for both). The 5-year EFS and OS rates were significantly higher in patients diagnosed between 2015 and 2019 than in patients diagnosed between 2007 and 2014 (P < 0.001). In total, 278 patients (26.7%) exhibited tumor relapse or progression; the median interval until relapse or progression was 14 months. Of the 233 patients who died, 83% died of relapse or progression of neuroblastoma and 4.3% died of therapy-related complications.Interpretation:The 5-year OS rate was low in high-risk patients, compared with low-and intermediate-risk patients. Multidisciplinary care is critical for improvement of survival in pediatric patients with neuroblastoma. Additional treatment strategies should be sought to improve the prognosis of patients with high-risk neuroblastoma.
简介:AbstractMilitary training is intense, difficult and often dangerous, so all kinds of injuries or diseases frequently occur during training. Most of the previous studies and reviews on military training-related injuries focused on musculoskeletal system, whereas there are no reviews of abdominal injuries and diseases. Although the incidence of military training-related abdominal injuries and diseases is relatively low, the patients’ condition is often critical especially in the presence of abdominal organ injury, leading to multi-organ dysfunction syndrome and even death. This paper elaborates on common types of military training-related abdominal injuries and diseases as well as the prevention and treatment measures, which provides some basis for scientific and reasonable training and improvement of medical security.
简介:AbstractTreatment of multiple myeloma (MM) has advanced dramatically in the past two decades. However, under the conditions of the COVID-19 pandemic, treatment strategies have been modified accordingly. Numerous novel agents, updated trials, and major advances in myeloma have been reported in the American Society of Hematology 2020 annual meeting, either for transplant-eligible or ineligible patients. Hot topics such as the significance of autologous stem cell transplantation (ASCT), development of novel agents, and chimeric antigen receptor-T (CAR-T) cells have been widely discussed. The triplet regimen bortezomib, lenalidomide, and dexamethasone (VRd) is recommended as the standard first-line treatment, and the addition of a fourth drug improves efficacy and survival. The value of ASCT remains undoubtful, even in the era of quadruplet induction. Dual-drug maintenance, including proteasome inhibitors and immunomodulatory drugs, overcomes unfavorable outcomes in high-risk patients. For relapsed/refractory myeloma (RRMM) patients, novel agents such as selinexor and venetoclax are superior. CAR-T cells and other cell-surface-targeted therapies also appear promising.
简介:AbstractPost-traumatic osteomyelitis (PTO) is a worldwide problem in the field of orthopaedic trauma. So far, there is no ideal treatment or consensus-based gold standard for its management. This paper reviews the representative literature focusing on PTO, mainly from the following four aspects: (1) the pathophysiological mechanism of PTO and the interaction mechanism between bacteria and the body, including fracture stress, different components of internal fixation devices, immune response, occurrence and development mechanisms of inflammation in PTO, as well as the occurrence and development mechanisms of PTO in skeletal system; (2) clinical classification, mainly the etiological classification, histological classification, anatomical classification and the newly proposed new classifications (a brief analysis of their scope and limitations); (3) imaging diagnosis, including non-invasive examination and invasive examination (this paper discusses their advantages and disadvantages respectively, and briefly compares the sensitivity and effectiveness of the current examinations); and (4) strategies, including antibiotic administration, surgical choices and other treatment programs. Based on the above-mentioned four aspects, we try to put forward some noteworthy sections, in order to make the existing opinions more specific.
简介:AbstractGastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the digestive system and are not sensitive to traditional chemotherapy. Therefore, historically, surgical resection was the only effective therapy. However, the emergence of tyrosine kinase inhibitors (TKIs) has revolutionized the treatment of GISTs, because they target c-Kit and PDGF receptor-α (PDGFRA), which are important in GIST development and progression. As research into c-Kit and PDGFRA continues, an increasing number of different TKIs are being used in the clinical setting. This review aims to discuss the current state of chemotherapy for the treatment of GISTs with different genotypes.
