Chronic inflammatory states: their relationship to cancer prognosis and symptoms

Abstract:
A chronic inflammatory state (CIS) commonly accompanies advanced cancers. Elements of a CIS include aberrant immune system activity and changes in hypothalamic-neuroendocrine control mechanisms. The end result is stimulation of tumour growth and metastases. In addition to tumour stimulation, cancer symptoms may be enhanced. While for most symptoms correlation with a CIS remains tenuous, clearly a CIS is linked to the aetiology of the cancer anorexia-cachexia syndrome. To date clinical studies aimed at a CIS are modest, but the increased understanding of the partnership of a CIS, cancer progression and anorexia-cachexia must lead to targeting a CIS in concert with conventional efforts to directly destroy tumour tissue.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
