• Repeat every 2 weeks

Adjuvant treatment for stage III colon cancer

• 12 cycles, every 2 weeks, according to the dose schedule above, for a total of 6 months
• Adjuvant use follows tumor resection

Dosage Modification

If persistent Grade 2 neuropathy, decrease dose to 75 mg/m²  

If persistent Grade 3 neuropathy, consider discontinuing oxaliplatin

After recovery from grade 3/4 GI or grade 3/4 hematological toxicity: Decrease dose to 75 mg/m² , AND decrease 5-FU by 20% (300 mg/m² bolus, 500 mg/m² infusion)

After recovery from grade 3/4 GI or hematologic toxicities

• Advanced colorectal cancer: Decrease dose to 65 mg/m² , AND decrease 5-FU by 20% (300 mg/m² bolus, 500 mg/m² infusion)
