Abstract

Forty-nine patients with chest wall recurrences of breast carcinoma received radiation therapy and 915-MHz microwave hyperthermia for 95 lesions. Follow-up ranged from 3 to 39 months, with five patients dying before 6 months follow-up. At 1 month follow-up, 49 (52%) of 95 lesions showed complete response; 28 (29%), partial response; and 18 (19%), no change. At 6 or more months follow-up, 54 (67%) of 81 lesions demonstrated local control; 10 (12%), partial response; six (7%), no change; and 11 (14%), local-regional recurrences. Superficial blisters occurred in 24 (25%) of 95 lesions, whereas long-term complications (deep necrosis, subcutaneous burns) occurred in seven (7%) lesions. Relapse occurred in 16 (17%) lesions, seven after initial complete response and nine after partial response. Several prognostic treatment factors were identified: applied radiation dose (greater than 30 Gy, P less than .01), size of tumor (less than 6 cm diameter, P less than .001), minimum tumor temperature (greater than 41 degrees C, P less than .001), and status of disease (M0 or M1 vs M2, P less than .001). Treatment complications were correlated with maximum temperatures (greater than 45 degrees C, P less than .001). In summary the palliative tre...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

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

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
