Role of CalciumMagnesium Infusion in Oxaliplatin Based Chemotherapy for Colorectal Cancer Patients Cancer Network. The incidence of colorectal cancer CRC has been decreasing over the past 2 decades, from 6. It is believed that the increases in screening have allowed early detection and removal of colorectal polyps before they progress to cancer. However, approximately 1. CRC consisting of 1. This makes CRC the fourth most common malignancy behind lung, prostate, and breast cancer, and accounts for approximately 1. In addition, the mortality rates from CRC have decreased over the past 2 decades. This decrease reflects declining incidences rates and improvements in early detection and treatment. However, an estimated 4. CRC were expected to occur in 2. The lifetime risk of being diagnosed with colorectal cancer is about 5, with 9. The incidence is higher in patients with specific inherited conditions that predispose them to the development of CRC, such as familial adenomatus polyposis, hereditary nonpolyposis colorectal cancer Lynch syndrome, Peutz Jeghers syndrome, and juvenile polyposis. In the United States, the median age at diagnosis of CRC is 7. Even when metastatic, CRC is a highly treatable and potentially curable disease. Death rates from CRC have declined progressively since the mid 1. United States and in many other Western countries. Two major factors are the evolving advanced technology to diagnose CRC in earlier stages, and the development of more effective adjuvant chemotherapies. However, survival rates are stage dependent, and the stage of the tumor is an important prognostic indicator of survival in early colon cancer. Average 5 year survival rates in colon cancer, by stage, are4,5 stage I T12, N0 9. II T34, N0 7. III T14, N12 5. IV any T, any N, M1 8 Management of colon cancer depends on the stage of diagnosis, but generally includes surgical resection and chemotherapyalone or in combination with other modalities eg, radiofrequency ablation. The development of adjuvant chemotherapy anticancer drugs in addition to surgery or radiation has been significant in prolonging the survival rate. Fluorouracil 5 FU was the initial chemotherapy proven to reduce mortality in the CRC patient. Later, it was found that adding leucovorin, a reduced folate, would increase the efficacy of 5 FU by increasing thymidylate synthetase inhibition and improving clinical outcomes. Interest in adjuvant chemotherapy was revived in the late 1. FUbased combination regimens and by the discovery of modulators of 5 FU activity such as leucovorin and levamisole, an immunomodulatory agent. In the late 1. 98. Eloxatin was found to have activity in advanced CRC, and it is the only platinum derivative with activity against advanced CRC. It binds and cross links strands of DNA, forming DNA adductsthus inhibiting DNA replication and transcription. Oxaliplatin also displays synergistic in vitro cytotoxicity with 5 FU against human colorectal cell lines. A potential mechanism for this synergism is the downregulation of thymidylate synthase by oxaliplatin, which thereby potentates the efficacy of 5 FU. The combination of oxaliplatin plus 5 FUleucovorin is known as the FOLFOX regimen, and it has become a standard regimen for CRC, both as adjuvant therapy and as treatment for metastatic disease. The use of the FOLFOX regimen as adjuvant treatment for colon cancer was confirmed by the Multicenter International Study of OxaliplatinFluorouracilLeucovorin in the Adjuvant Treatment of Colon Cancer MOSAIC. This study concluded that adding oxaliplatin to a regimen of 5 FU and leucovorin improves the adjuvant treatment of colon cancer. The investigators randomly assigned 2,2. II or III colon cancer to receive 5 FU alone or with oxaliplatin for 6 months. The primary endpoint was disease free survival. The result showed that the rate of disease free survival at 3 years was 7. FUleucovorin plus oxaliplatin vs 7. FUleucovorinonly group P. In metastatic disease, patients treated with FOLFOX had a response rate, time to disease progression, and overall survival time that were superior to those observed with other combination chemotherapies, including IFL irinotecan plus 5 FU or IROX irinotecan plus oxaliplatin. These data support the use of oxaliplatin based chemotherapy as the preferred first line combination chemotherapy for metastasis colorectal cancer. Unfortunately, platinum based chemotherapies also produce neurotoxicity as a side effect. Neurotoxicity is the most common dose limiting toxicity of oxaliplatin. The grading and severity of oxaliplatin induced neurotoxicity is shown in Table 1. It can manifest as either of two distinct syndromes a transient, acute syndrome that can appear during or shortly after the infusion around 12 of patients, and a dose limiting, cumulative sensory neuropathy 1. Hp Compaq Invalid Electronic Serial Number. This neurotoxicity is induced or exacerbated by cold and prolonged muscular contraction after a voluntary contraction, and it is one of the major causes for patients to stop receiving chemotherapy. However, patients with neurotoxicity have no signs or very mild signs of axonal degeneration on clinical neurophysiologic examinations and nerve biopsy study. This means that oxaliplatin has a direct effect on the excitability of sensory neurons and muscle cells. Several studies have been done to propose the possible explanation of the pathogenesis. Biotransformation of oxaliplatin produces oxalate ions, which are able to chelate calcium. Calcium binds within the pore of the sodium channel and enhances the rate of closing of the activation gates of the voltage gated sodium channel. Therefore, oxalate, acting as a calcium chelator, may interact with the sodium channel by chelating calcium and interfering with sodium channel activity, leading to a decrease of the channel deactivation rate, and thus increasing neuronal hyperexcitability. In 2. 00. 4, Gamelin et al published a clinical trial and concluded that calcium and magnesium infusion significantly reduced the incidence and severity of peripheral neuropathy secondary to oxalipatin. They administered 1 g of calcium gluconate Ca and 1 g of magnesium sulfate Mg as an infusion, 1 or 2 hours prior to the oxaliplatin infusion and soon after the oxaliplatin drip finished. In their retrospective cohort of 1. FUleucovorin for advanced colorectal cancer, the percentage of patients with grade 3 distal paresthesia was significantly lower in the CaMg group 7 vs 2. P. 0. 01. The study also reported less neuropathy in the CaMg group at the end of the treatment 2. P. 0. 03. 2. 5,3. However, the CONce. PT Combined Oxalipatin Neurotoxicity Prevention Trial study, a clinical trial of 1. CaMg infusion to reduce the neurotoxicity, was prematurely terminated in 2. The independent data monitoring committee found that the CaMg infusion reduced the efficacy of the chemotherapy regimen. Based on their central radiology review, the response rate associated with oxaliplatin could be reduced up to 5. Another trial, from The North Central Cancer Treatment Group NCCTGthe N0. C7 trialalso showed a positive result. Despite its early termination following the CONce. PT study, this prospective, randomized and double blinded trial that enrolled 1. FOLFOX regimen demonstrated that the CaMg infusions delayed the time to onset of grade 2 sensory neural toxicity.
