In Greek mythology, after a fruitless 10-year siege on the city of Troy, an attacking Greek army built a huge figure of a horse as a trophy to its enemy. Hidden inside was a select force of men who surprised, defeated and overtook Troy.
A similar tactic is being considered in the advancement against breast cancer.
Cheryl Espinosa had cancer in 2005. Doctors believed she had an 84% chance of not having the cancer return, but it did.
"It did come back full force stage IV metastatic breast cancer," said Cheryl Espinosa, who is a participant in clinical trials. "I opted to go on the TDM trial, which I was lucky enough to be eligible for."
Oncologist Dr. Charles Vogel has been conducting that clinical trial on the drug TDM-1, which he metaphorically compares to Greek mythology's Trojan Horse, in which an attacking force used a completely different tactic to overtake the city of Troy.
Dr. Vogel explains that his trial seeks a cancer treatment for patients who have not responded well to other treatments.
"TDM1 is equivalent to a Trojan Horse," said Dr. Vogel, "where the drug Herceptin is linked to a form of chemotherapy, and the Herceptin will bring the chemotherapy directly to the tumor cell."
The drug was used in a population of patients initially who had failed many different lines of therapy. And even in a very heavily treated population, 30% of the patients responded.
To put that in perspective, in the usual phase I trial of most drugs, the likelihood of a response is about 3 percent. It worked for Cheryl, who added, "I was on that for five months. After one treatment I had complete resolution systemically."
Unfortunately, Cheryl's cancer later spread to her brain, and she had to leave the trial but never regretted the opportunity.
