When do you give leucovorin?
Leucovorin is also given with a chemotherapy agent called methotrexate, but in this case it is given to "rescue" normal, healthy cells from the damage caused by the methotrexate. In order to give the methotrexate time to kill the cancer cells, leucovorin is started 12-24 hours after the methotrexate is given.
How does leucovorin work with 5-FU?
5-Fluorouracil (5-Fu) and leucovorin (LV) are often given in combination to treat colorectal cancer. 5-Fu/LV prevents cell proliferation by inhibiting thymidylate synthase, which catalyzes the conversion of deoxyuridine monophosphate to deoxythymidine monophosphate.

What is the best adjuvant treatment for stage 3 colon cancer?
The demonstration that postoperative adjuvant treatment with fluorouracil and levamisole reduced the mortality rate by 33 percent among patients with stage III colon cancer 4 prompted several trials, which established six months of treatment with fluorouracil plus leucovorin (FL) as the standard adjuvant chemotherapy for stage III colon cancer. 5-11 Oxaliplatin is a third-generation platinum derivative, which, when combined with fluorouracil and leucovorin, is among the most effective chemotherapies for metastatic colorectal cancer. 12-15 To determine whether oxaliplatin can also benefit patients with disease in an earlier stage, we conducted an international phase 3 clinical trial in patients with stage II or III colon cancer — the Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer (MOSAIC).
What is the hazard ratio for recurrence in the group given FL plus oxalip?

What is the interaction test for colon cancer?
A test for interaction is an appropriate statistical approach to the question of whether the benefit of adjuvant treatment differs between stage II and stage III colorectal cancer. 23 In our study, this test showed no significant interaction between the stage of disease and the treatment, indicating that FL plus oxaliplatin benefited both stage II and stage III colorectal cancer. From a clinical standpoint, stage II colon cancer occurs in a heterogeneous, node-negative population in which clinical and biologic prognostic factors other than the status of lymph-node involvement need to be taken into account. Tools are being developed to help physicians assess the risk–benefit ratio of adjuvant chemotherapies for individual patients. 22
What is the best treatment for colon cancer?
The standard adjuvant treatment of colon cancer is fluorouracil plus leucovorin (FL). Oxaliplatin improves the efficacy of this combination in patients with metastatic colorectal cancer. We evaluated the efficacy of treatment with FL plus oxaliplatin in the postoperative adjuvant setting.
How long is a FL infusion?
Eligible patients were randomly assigned to receive FL alone or with oxaliplatin. In the FL group, each cycle comprised a 2-hour infusion of 200 mg of leucovorin per square meter of body-surface area followed by a bolus of 400 mg of fluorouracil per square meter and then a 22-hour infusion of 600 mg of fluorouracil per square meter given on 2 consecutive days every 14 days, for 12 cycles. In the group given FL plus oxaliplatin, the same FL regimen was used, plus a two-hour infusion of 85 mg of oxaliplatin (Eloxatin, Sanofi-Synthelabo) per square meter on day 1, given simultaneously with leucovorin, with the use of a Y infusion device. The use of disposable pumps (LV5 infusors, Baxter Healthcare) allowed outpatients to receive a continuous infusion of fluorouracil.
What are the adverse effects of oxaliplatin?
Neutropenia, diarrhea, and vomiting were the most frequent grade 3 or 4 adverse effects in the group given FL plus oxaliplatin ( Table 2 ). Grade 3 or 4 neutropenia was much commoner with FL plus oxaliplatin than with FL (41.1 percent vs. 4.7 percent, P<0.001) but was complicated by fever or infection in only 1.8 percent of cases (20 patients) in the group given FL plus oxaliplatin and in 0.2 percent of cases (2 patients) in the FL group (P<0.001). The incidence of thromboembolic events among patients who received at least one cycle of the assigned regimen was similar in the two groups (63 of 1108 patients [5.7 percent] and 72 of 1111 patients [6.5 percent], respectively).
How often are patients assessed for chemo?
Patients were assessed before randomization, every two weeks during treatment, and then every six months for five years. The baseline assessment involved a medical history taking, physical examination, biologic tests, measurement of the carcinoembryonic antigen level, chest radiography, and abdominal ultrasonography or computed tomography. Patients were monitored for adverse effects throughout the treatment period and until 28 days after the last cycle of chemotherapy, unless treatment-related adverse effects required additional follow-up.
How is the FOLFOX regimen given?
The FOLFOX regimen is an intravenous (IV) infusion, meaning it’s slowly given directly in a vein. Most of the FOLFOX medications should be given at an infusion center, either at an oncologist's (cancer specialist’s) office or at a hospital. This is because a healthcare provider or nurse will very closely watch you for allergic reactions and side effects during your infusion.

What is the best chemotherapy for colorectal cancer?
A common chemotherapy regimen used for colorectal cancer is FOLFOX.
How long does it take for Folfox to cure cancer?
In the MOSAIC trial discussed earlier, 78% of participants using FOLFOX had disease-free survival after 3 years of using the regimen. This means there was no sign of cancer for 3 years after completing FOLFOX treatment. Researchers also noted that using FOLFOX lowered the risk of cancer returning by 23% compared to only using 5-FU and leucovorin.
Does Folfox slow the spread of cancer?
In the MOSAIC trial, FOLFOX slowed the growth and spread of cancer cells more effectively for people with stage 3 colorectal cancer than the combination of 5-FU and leucovorin. It wasn’t as helpful for people with stage 2 colorectal cancer.
