Expert consensus on resection of chest wall tumors and chest wall reconstruction.

Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon. In January 2019, 73 experts in thoracic surgery, plastic surgery, science, and engineering jointly released the Chinese Expert Consensus on Chest Wall Tumor Resection and Chest Wall Reconstruction (2018 edition). After that, numerous experts put forw

Plumbagin, a Biomolecule with (Anti)Osteoclastic Properties.

Plumbagin is a plant-derived naphthoquinone that is widely used in traditional Asian medicine due to its anti-inflammatory and anti-microbial properties. Additionally, plumbagin is cytotoxic for cancer cells due to its ability to trigger reactive oxygen species (ROS) formation and subsequent apoptosis. Since it was reported that plumbagin may inhibit the differentiation of bone resorbing osteoclasts in cancer-related models, we wanted to elucidate whether plumbagin interferes with cytokine-induced osteoclastogenesis. Using C57BL/6 mice, we unexpectedly found that plumbagin treatment enhanced o

Рекомендации Международной группы по работе с миеломой по диагностике и лечению изолированных плазмоклеточных опухолей.

Приблизительно 50% СП прогрессируют в симптоматическую миелому в течение 5 лет после начальной определенной локальной радиотерапии. Увеличение доступности улучшенных диагностических и монит

Prospects and Advances in Adoptive Natural Killer Cell Therapy for Unmet Therapeutic Needs in Pediatric Bone Sarcomas.

Malignant bone tumors are aggressive tumors, with a high tendency to metastasize, that are observed most frequently in adolescents during rapid growth spurts. Pediatric patients with malignant bone sarcomas, Ewing sarcoma and osteosarcoma, who present with progressive disease have dire survival rates despite aggressive therapy. These therapies can have long-term effects on bone growth, such as decreased bone mineral density and reduced longitudinal growth. New therapeutic approaches are therefore urgently needed for targeting pediatric malignant bone tumors. Harnessing the power of the immune

Abscopal Effects in Metastatic Cancer: Is a Predictive Approach Possible to Improve Individual Outcomes?

Patients with metastatic cancers often require radiotherapy (RT) as a palliative therapy for cancer pain. RT can, however, also induce systemic antitumor effects outside of the irradiated field (abscopal effects) in various cancer entities. The occurrence of the abscopal effect is associated with a specific immunological activation in response to RT-induced cell death, which is mainly seen under concomitant immune checkpoint blockade. Even if the number of reported apscopal effects has increased since the introduction of immune checkpoint inhibition, its occurrence is still considered rare and

Cancer cachexia--pathophysiology and management.

About half of all cancer patients show a syndrome of cachexia, characterized by anorexia and loss of adipose tissue and skeletal muscle mass. Cachexia can have a profound impact on quality of life, symptom burden, and a patient's sense of dignity. It is a very serious complication, as weight loss during cancer treatment is associated with more chemotherapy-related side effects, fewer completed cycles of chemotherapy, and decreased survival rates. Numerous cytokines have been postulated to play a role in the etiology of cancer cachexia. Cytokines can elicit effects that mimic leptin signaling a

Glucocorticoid-induced osteonecrosis in systemic lupus erythematosus patients.

Osteonecrosis (ON) is a complex and multifactorial complication of systemic lupus erythematosus (SLE). ON is a devastating condition that causes severe pain and compromises the quality of life. The prevalence of ON in SLE patients is variable, ranging from 1.7% to 52%. However, the pathophysiology and risk factors for ON in patients with SLE have not yet been fully determined. Several mechanisms for SLE patients' propensity to develop ON have been proposed. Glucocorticoid is a widely used therapeutic option for SLE patients and high-dose glucocorticoid therapy in SLE patients is strongly assoc

Endocrine sequelae of hematopoietic stem cell transplantation: Effects on mineral homeostasis and bone metabolism.

Hematopoietic stem cell transplantation (HSCT) is an established therapeutic strategy for the treatment of malignant (leukemia and lymphoma) and non-malignant (thalassemia, anemia, and immunodeficiency) hematopoietic diseases. Thanks to the improvement in patient care and the development of more tolerable conditioning treatments, which has extended the applicability of therapy to the elderly, a growing number of patients have successfully benefited from HSCT therapy and, more importantly, HSCT transplant-related mortality has consistently reduced in recent years. However, concomitantly to long

… Indeed, HSCT patients less than 10 years were showed to have, at an average age of 14 years after the transplantation, significantly lower Z-scores at lumbar spine and femur neck than HSCT patients transplanted at over 18 years and non-transplanted sibling controls ( 111 ). …

Could Local Application of Hypoxia Inducible Factor 1-α Enhancer Deferoxamine Be Promising for Preventing of Medication-Related Osteonecrosis of the Jaw?

This experimental study investigates the prophylactic effect of deferoxamine (DFO) on medication-related osteonecrosis of the jaw (MRONJ). Thirty-six female Sprague Dawley rats received zoledronic acid (ZA) for eight weeks to create an osteonecrosis model. DFO was locally applied into the extraction sockets with gelatin sponge (GS) carriers to prevent MRONJ. The specimens were histopathologically and histomorphometrically evaluated. Hypoxia-inducible factor 1-alpha (HIF-1α) protein levels in the extraction sockets were quantified. New bone formation rate differed significantly between groups (

Rare Diseases of the Nose, the Paranasal Sinuses, and the Anterior Skull Base.

Due to their low incidence and thus resulting limited diagnostic criteria as well as therapeutic options, rare diseases of the nose, the paranasal sinuses, and the anterior skull base are a significant challenge. The value as of which a disease has to be considered as rare amounts to a maximum of 5 patients per 10 000 people. Within these diseases, however, there are extreme differences. Some rare or orphan diseases like for example the inverted papilloma belong to regularly diagnosed and treated diseases of larger departments of oto-rhino-laryngology whereas other rare diseases and malformati

Bone health in patients with cancer: a SEOM-SEIOMM consensus review of risk factors, assessment strategies, and management approaches.

Anticancer therapies frequently compromise skeletal health and increase fracture risk. This narrative review synthesizes information and provides guidance on assessment, prevention, and management of therapy-related bone loss in adults with cancer. Major contributors to bone loss in this population include aromatase inhibitors, androgen deprivation therapy, systemic glucocorticoids, chemotherapy, and selected targeted or immune agents. Recommended assessments include clinical evaluation, laboratory tests (calcium, vitamin D, and renal function), and bone mineral density by dual-energy X-ray ab

The Role of IL-33/ST2 Pathway in Tumorigenesis.

Cancer is initiated by mutations in critical regulatory genes; however, its progression to malignancy is aided by non-neoplastic cells and molecules that create a permissive environment known as the tumor stroma or microenvironment (TME). Interleukin 33 (IL-33) is a dual function cytokine that also acts as a nuclear factor. IL-33 typically resides in the nucleus of the cells where it is expressed. However, upon tissue damage, necrosis, or injury, it is quickly released into extracellular space where it binds to its cognate receptor suppression of tumorigenicity 2 (ST2)L found on the membrane o

Management of Bone Health Considerations in Patients with Cancer.

Background: Older adults with cancer are surviving longer due to earlier detection and more effective treatments for advanced stages. This population is at an elevated risk of osteoporosis due to age-related changes in bone density as well as the impact of cancer and cancer treatments on the skeletal system. Main Body: Cancer treatments are associated with increased bone loss and fracture risk via a variety of mechanisms. International guidelines recommend screening for cancer treatment-induced bone loss and provide treatment algorithms for pharmacological agents for those on hormonal therapy.

Early-Onset Osteoporosis: Rare Monogenic Forms Elucidate the Complexity of Disease Pathogenesis Beyond Type I Collagen.

Early-onset osteoporosis (EOOP), characterized by low bone mineral density (BMD) and fractures, affects children, premenopausal women and men aged <50 years. EOOP may be secondary to a chronic illness, long-term medication, nutritional deficiencies, etc. If no such cause is identified, EOOP is regarded primary and may then be related to rare variants in genes playing a pivotal role in bone homeostasis. If the cause remains unknown, EOOP is considered idiopathic. The scope of this review is to guide through clinical and genetic diagnostics of EOOP, summarize the present knowledge on rare monoge

Psychometric properties and clinical utility of the EORTC QLQ-BM22 in patients with bone metastases: a systematic review.

BackgroundThe European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for bone metastases 22 (EORTC QLQ-BM22) is a site-specific health-related quality-of-life instrument for patients with bone metastases. However, modern treatments and extended survivorship have introduced new toxicity profiles and clinical challenges. We systematically assessed the measurement performance of QLQ-BM22 to determine if contemporary evidence supports updating the module.MethodsA search was conducted using Medline, Embase, and Cochrane Central Register of Controlled Trials from in

Understanding and Managing Fracture Risk in Patients With Cancer: A Literature Review.

One of the most important complications of cancer and its treatments is the increased fracture risk. Fractures can have a significant impact on the patient's quality of life and may be associated with morbidity, mortality, and reduced functional status. The present study aims to investigate the mechanisms underlying the increased risk of fractures in cancer patients, the effect of cancer treatments on fracture risk, and strategies to prevent fractures in this population. This is a literature review using the PubMed - National Center for Biotechnology Information (NCBI), Web of Science, Cochran

An updated overview of the search for biomarkers of osteoporosis based on human proteomics.

Osteoporosis is a chronic metabolic disease that increases bone fragility and, leads to severe osteoporotic fractures. In recent years, the use of high-throughput omics to explore physiological and pathological biomarkers related to bone metabolism has gained popularity. In this review, we first briefly review the technical approaches of proteomics. Additionally, we summarize the relevant literature in the last decade to provide a comprehensive overview of advances in human proteomics related to osteoporosis. We describe the specific roles of various proteins related to human bone metabolism,
