Role of Calcium/Magnesium Infusion in Oxaliplatin-Based Chemotherapy for Colorectal Cancer Patients

March 22, 2010

The combination of oxaliplatin plus fluorouracil/leucovorin is known as the FOLFOX regimen, and it has become a standard regimen for colorectal cancer (CRC), both as adjuvant therapy and as treatment for metastatic disease. Unfortunately, platinum-based chemotherapies also produce neurotoxicity as a side effect. Neurotoxicity is the most common dose-limiting toxicity of oxaliplatin, and it is one of the major causes for patients to stop receiving chemotherapy. It can manifest as either of two distinct syndromes: a transient, acute syndrome that can appear during or shortly after the infusion (~1%–2% of patients), and a dose-limiting, cumulative sensory neuropathy. Calcium/magnesium (Ca/Mg) infusions have been used to decrease the incidence of oxaliplatin-induced neuropathy. The actual utility of Ca/Mg infusions in this setting has been an interesting and controversial topic. They may reduce the severity of neurotoxicity, but some investigators have questioned whether they also will alter the efficacy of these chemotherapy regimens. In this paper, we review the clinical data concerning the usefulness of Ca/Mg infusions in reducing the incidence of oxaliplatin-induced neuropathy as well as their effect on responsiveness to chemotherapy.

Commentary (Weitberg): Chronic Inflammation and Cancer

February 01, 2002

In this article, Drs. Shacter and Weitzman present a thoughtful, comprehensive review of the role of chronic inflammation in the multistep process of carcinogenesis. Their cogent discussion encompasses the basic science, clinical correlates, and treatment implications of this subject. It is well balanced, highly informative, and indicative of the complexity of the biochemical events that transpire as chronic inflammation results in malignant transformation of target cells.

Nonionizing Electromagnetic Fields and Cancer: A Review

Low-frequency electromagnetic radiation had previously been thought to cause human injury only by generation of excess heat or by shock from direct contact with electric current. Information accumulating over the past few
