He made it to the other side of Stage 4 colorectal cancer. How?

Philip Felshman, diagnosed with Stage IV colorectal cancer in January 2025, faced a dire prognosis as the disease had metastasized to his liver and lungs. However, after undergoing a novel treatment called hepatic artery infusion (HAI), which delivers high-dose chemotherapy directly to the liver, Felshman achieved remarkable results, with significant tumor reduction and is now cancer-free. This treatment is not universally applicable and requires careful patient selection and monitoring, emphasizing the importance of timely referrals to specialized centers. As HAI gains traction as a growing cancer care paradigm, awareness and early detection remain crucial for improving outcomes in colorectal cancer patients.

Dive Deeper:

  • Felshman experienced alarming symptoms before his diagnosis, struggling to walk up stairs, which led to the discovery of his condition. His prognosis initially indicated only a few years to live.

  • The hepatic artery infusion (HAI) pump was a critical part of Felshman's treatment, enabling higher concentrations of chemotherapy directly to the liver, which is crucial for targeting metastasized tumors.

  • Dr. Nicholas Hornstein, Felshman's oncologist, noted that only 10% to 15% of colorectal cancer patients are suitable for HAI treatment, highlighting a significant treatment gap in oncology.

  • Despite the success of HAI, it is not suitable for all patients, particularly those with extensive prior chemotherapy or those whose cancer has spread beyond the liver.

  • Complications from HAI can include pump malfunctions and potential liver damage from the intense chemotherapy doses, necessitating a highly experienced medical team for safe administration.

  • Felshman urges others to prioritize early screenings and to advocate for their health by asking questions and seeking second opinions if they do not feel comfortable with treatment plans.

  • The challenge remains for medical centers to expand HAI availability due to the specialized skills required, though its recognition as a treatment option is increasing.
