Malignanc

Importance: Impaired skin barrier and aberrant immune function in atopic dermatitis (AD) may alter immune response to malignant cancer. Conflicting data exist on the risk of cancer in patients with AD. Objective: To assess the risk of noncutaneous and cutaneous cancers in patients with AD compared with the general population without AD. Data Sources: Studies identified from searches of MEDLINE and Embase that were published from 1946 and 1980, respectively, to January 3, 2019...

Helicobacter pylori (H. pylori) remains a prevalent, worldwide, chronic infection. Though the prevalence of this infection appears to be decreasing in many parts of the world, H. pylori remains an important factor linked to the development of peptic ulcer disease, gastric malignanc and dyspeptic symptoms. Whether to test for H. pylori in patients with functional dyspepsia, gastroesophageal reflux disease (GERD), patients taking nonsteroidal antiinflammatory drugs, with iron deficiency anemia, or who are at greater risk of developing gastric cancer remains controversial...

The sentinel observations made by William B. Coley. M.D. in the 1890s that patients with malignancics can respond to the intratumoral inoculation of live bacterial organisms or bacterial toxins became the cornerstone for the development of immunotherapy for cancers. It has been repeatedly demonstrated that tumors express unique proteins which can trigger an immune response. The adoptive transfer of immune cells to the host with established malignancy can mediate complete eradication of local or disseminated tumors and result in systemic immunity...
