Simple blood test can accurately predict neuroendocrine tumor response to radiopharmaceutical therapy
While biomarkers have been used to predict the outcomes of treatments for breast, prostate, and other cancers, there are currently no objective means to predict the efficacy of radiopharmaceutical therapy for neuroendocrine tumors.
A simple blood draw can provide physicians with valuable information that can determine if peptide receptor radionuclide therapy (PRRT) is likely to be effective in a patient with neuroendocrine cancer. The blood-based biomarker PPQ can predict which patients will respond to PRRT with 96 percent accuracy; changes in another biomarker, NETest, correctly correlate with PRRT response in 90 percent of patients. The study, published in the April issue of The Journal of Nuclear Medicine, opens new possibilities of tailoring radiopharmaceutical treatment to patients.

Study suggests omicron to appear more deadly than seasonal influenza
Influenza and COVID-19 are both respiratory diseases with similar modes of transmission. In December 2021, influenza re-emerged in Israel after it went undetected since March 2020. At the same time, the Omicron had substituted Delta as the predominant variant. But data directly comparing Omicron with seasonal influenza are scarce.
