Daniel Flora: From Stage IV Cancer to Remission – Clinical Trials Made This Possible

Daniel Flora, Medical Director of Oncology Research at St. Elizabeth Healthcare, shared a post on Substack:

“This morning, I saw three patients in clinic, all with stage IV cancer:
  •  One with cutaneous squamous cell carcinoma that had spread to the lymph nodes
  •  One with HPV-positive tonsil cancer metastatic to the lungs
  •  One with melanoma of the chest wall that had also spread to the lungs
Each was started on treatment for several months with a PD-1 inhibitor pembrolizumab (Keytruda) or cemiplimab (Libtayo), a type of cancer immunotherapy.
And today, all three patients had no evidence of disease on their PET/CT scans, a complete response.
I got to share the news that their scans were clear, that there was no sign of cancer.
It’s hard to describe what it feels like to be part of that moment. After all these years it’s still quite emotional to see the relief of a patient waiting to hear the news, good or bad.
Just a few years ago, these same patients would’ve been getting chemotherapy or radiation often with significant side effects and no clear path forward. Now, they’re living their lives normally, feeling well, and cancer free.
For patients who respond to immunotherapy, these remissions can be durable. Some go on to live for years without recurrence. Some are cured.
Clinical trials made this possible. Industry partners helped bring these therapies to patients. And the patients themselves contributed by participating in something uncertain to help others and advance the science.
When I started ten years ago, I would’ve called today miraculous.
Honestly, I still do.”
