Nicholas Hornstein: NICHE-2 Absolutely Delivers: Game Over for Chemo in dMMR Colon Cancer

Nicholas Hornstein, Gastrointestinal Medical Oncologist at Northwell Health, shared a post on LinkedIn:

“NICHE-2 absolutely delivers. Game over for chemo in dMMR colon cancer

In locally advanced dMMR colon cancer, FOxTROT already showed us chemo doesn’t work, and now NICHE-2 makes it undeniable.

Neoadjuvant nivolumab + ipilimumab 

  •  99% pathologic response
  •  67% pathologic CR
  •  Zero recurrences to date at 3 years

This is the final coffin nail for perioperative chemotherapy in this setting. ATOMIC is already on life support despite being published less than a year ago.

The real question now: with Cercek’s rectal data, can we safely omit surgery next? At minimum, this should be the new standard. At maximum, it’s the start of a paradigm shift.”
