People with locally advanced esophageal cancer treated with chemotherapy both before and after surgery lived considerably longer
- Thread starter ginfreely
- Start date
A large clinical trial looks to have settled a debate over how best to treat most people with locally advanced esophageal cancer, where the disease has spread just outside of the esophagus but not to other parts of the body.
Typically, these people get one of two treatments: chemotherapy followed by surgery and then more chemotherapy, or chemotherapy and radiation followed by surgery and no further treatment.
It’s been unclear, however, if one approach was more effective than the other.
In the trial, people treated with chemotherapy both before and after surgery, which is known as perioperativechemotherapy, lived considerably longer than those who received chemotherapy and radiation before surgeryExit Disclaimer, known as neoadjuvant treatment.
Based on the study’s findings, perioperative chemotherapy should be the recommended approach for people with locally advanced esophageal cancer, said Jens Hoeppner, M.D., of the University of Bielefeld in Germany, who led the study. Dr. Hoeppner presented the findings at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago on June 2.
“The results have been long awaited among those of us who treat esophageal cancer,” said Karyn A. Goodman, M.D., of the Icahn School of Medicine at Mount Sinai in New York, who discussed the results during the meeting but was not involved in the study.

Dr. Goodman also noted, however, that the treatment landscape for esophageal cancer is rapidly evolving. Although it’s important to have some resolution to this particular debate, she said, newer treatments, including immunotherapies, are also now an option for people with locally advanced esophageal cancer.
In addition, researchers are also testing whether combining these regimens with other therapies can lead to even better outcomes for patients. In other words, she stressed, how locally advanced esophageal cancer is treated is going to continue to evolve in the coming years.
CROSS regimen: Radiation (41.4 Gy), along with five cycles of paclitaxel and carboplatin over 5 weeks, followed by surgery 4 to 6 weeks later.

Two standard of care treatment options
In the United States, it is estimated that more than 22,000 people will be diagnosed with esophageal cancer this year. Approximately half of these cases will be diagnosed at a locally advanced stage.FLOT versus CROSS Regimens
FLOT regimen: Four cycles of fluorouracil, leucovorin, oxaliplatin, and docetaxel over 8 weeks, followed by surgery 4 to 6 weeks later. After leaving the hospital, patients receive the same chemotherapy regimen 4 to 6 weeks later.CROSS regimen: Radiation (41.4 Gy), along with five cycles of paclitaxel and carboplatin over 5 weeks, followed by surgery 4 to 6 weeks later.
Surgery was long the primary treatmentfor locally advanced esophageal cancer. That changed over the past two decades, with several large trials showing that the addition of perioperative chemotherapy or neoadjuvant chemotherapy plus radiation therapy improved how long people lived.
From those trials, two options emerged as the recommended treatments: a perioperative chemotherapy regimen called FLOT and a neoadjuvant chemotherapy and radiation regimen called CROSS (see box).
With two proven, highly effective treatment approaches available, Dr. Hoeppner and his colleagues decided to launch a trial to answer a question that arose frequently among oncologists: Which one is best for their patients?
After completing treatment, 35 of the 191 patients in the FLOT group had complete disappearance of their tumor, known as a complete response, compared with 24 of the 180 patients in the CROSS group.
Patients who received the FLOT regimen lived a median of 5 years and 6 months, compared with about 3 years for patients in the CROSS group. Three years after completion of treatment, 57% of people in the FLOT group and 51% of patients in the CROSS group were still alive.
The rate of complications after surgery was similar among both groups. However, within 90 days of surgery, about 3% of participants in the FLOT group had died, compared with nearly 6% of participants in the CROSS group.

One regimen rises above the other
In the new trial, dubbed ESOPEC and funded by the German Research Foundation, 438 people with locally advanced esophageal cancer were randomly assigned to receive either perioperative chemotherapy with the FLOT regimen or neoadjuvant chemoradiation with the CROSS regimen.After completing treatment, 35 of the 191 patients in the FLOT group had complete disappearance of their tumor, known as a complete response, compared with 24 of the 180 patients in the CROSS group.
Patients who received the FLOT regimen lived a median of 5 years and 6 months, compared with about 3 years for patients in the CROSS group. Three years after completion of treatment, 57% of people in the FLOT group and 51% of patients in the CROSS group were still alive.

FLOT regime is what USA hospitals use for stomach cancer too.
