The chemotherapies of FOLFOX (leucovorin + 5-fluorouracil + oxaliplatin) and FOLFIRI (folinic acid + 5-fluorouracil + irinotecan) are effective for a variety of malignant tumors. In particular, the sequential chemotherapy of FOLFOX/FOLFIRI has become the preferred post-operational treatment approach for gastrointestinal cancer and an important palliative care program for advanced cancer. However, the sequential chemotherapy of FOLFOX/FOLFIRI showed severe side effects due to the fact that the toxicity of the drugs can be enhanced by each other. Here, we report the dynamic changes in the activities of serum ACTH, cortisol, renin, angiotensin, and aldosterone in patients following multiple cycles of FOLFOX/FOLFIRI sequential chemotherapy. We found that the sequential chemotherapy might cause damage to the activities of the endocrine cells and/or the sympathetic nerve, and alter endocrine function, specifically the ACTH-cortisol and renin-angiotensin-aldosterone axes.
The poly-lysine-linked membrane for colon carcinoma cells undergoing chemotherapy could produce the anti-membrane polyclonal antibodies (promising as novel antibody molecules for target therapy) and generate an effective immune attack on the surviving cancer cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
