Abstract

Twelve patients with telangiectatic osteogenic sarcoma (TOS) of the extremities were treated with neoadjuvant chemotherapy, according to two different protocols. Preoperatively the patients received high-dose methotrexate(HD-MTX)/cisplatinum(CPD) or HD-MTX/CPD/adriamycin(ADM). CPD was delivered intra-arterially, the other drugs intravenously. Limb salvage surgery was performed in eight instances and four patients underwent amputation. Post operative chemotherapy was tailored according to the grade of necrosis determined by preoperative treatment on the primary tumor. In ten cases (83%) the grade of necrosis resulted higher than 95%. The mean length of follow-up was 3.5 years with a range of 18 to 72 months. Ten patients (83%) remained continuously disease-free, while two patients developed lung metastases and died of uncontrolled disease. No local recurrences were observed. These results are better than those observed in 167 contemporary cases of conventional osteosarcoma treated with the same protocols. This study confirms that TOS is not always a lethal tumor as suggested by prior reports. Employing neoadjuvant chemotherapy a high percentage of patients with TOS can be cured and in most of them, limb sparing surgery is possib...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.
