“Reduced oxaliplatin exposure in gastrointestinal cancers: A
systematic review and meta-analysis”
We already know from maintenance trials in mCRC that stopping oxaliplatin after 3–4 months is not detrimental for PFS/OS and is associated with less neuropathy.
The question in 2026: what is the evidence in mCRC, the adjuvant setting, and other GI cancers? Is there a situation where oxaliplatin is still needed beyond 3–4 months of induction? In other words — is reduced oxaliplatin exposure associated with worse DFS or PFS across GI cancers?
We did a meta-analysis across GI cancers and settings:
• No statistically significant survival difference overall
• Lower neuropathy and grade ≥3 adverse events
Take-home: don’t keep oxaliplatin going beyond 3–4 months. These findings support limiting exposure to improve the therapeutic index of oxaliplatin-based chemo across GI settings.
