Esophageal Cancer Survivors Face Sharply Higher Fracture Risk After First Year

Esophageal cancer survivors face significantly elevated fracture risks starting one year after surgery, according to new research—the first study in Korea to demonstrate this link based on treatment history and post-operative time progression.

Samsung Medical Center announced on the 20th that a research team comprising Professors Shin Dong-wook and Kim Sung-hye from the Department of Family Medicine, Professor Cho Jong-ho from the Department of Thoracic and Esophageal Surgery, and Professor Han Kyung-do from Soongsil University's Department of Statistics and Actuarial Science published their findings in a recent issue of the European Journal of Surgical Oncology.

Esophageal cancer is the most lethal disease affecting the esophagus. Unlike the stomach and colon, the tube-shaped esophagus lacks a protective serosal layer, allowing cancer cells to spread easily to surrounding lymph nodes and adjacent organs. Early detection is critical because initial symptoms are absent and progression is rapid. Treatment varies depending on tumor location, stage, and patient condition, though early-stage cases can be cured through surgical removal of the esophagus and surrounding lymph nodes alone.

The research team analyzed National Health Insurance Service data, selecting 4,847 patients who underwent esophageal cancer surgery between 2009 and 2022, along with 14,541 individuals without cancer history, matched by sex and age. After tracking cancer patients for an average of five years and the control group for eight years, researchers found esophageal cancer survivors faced 46% higher overall fracture risk. Spinal fracture risk was elevated by 66%, while hip fracture risk exceeded 68%. The team attributed these findings to multiple factors including cancer-related chronic inflammation, post-surgical bone density decline, anemia, nutritional deterioration, and reduced physical activity.

Fracture risk varied significantly based on time elapsed since surgery. Within the first year post-operation, cancer history showed no significant impact on fracture risk. However, after one year, overall fracture risk climbed to 61%, with hip fracture risk soaring to 81%. These elevated risks persisted beyond five years, demonstrating a clear long-term pattern. Researchers suggest the divergence at the one-year mark may reflect reduced falls during the immediate post-operative period when physical activity is limited.

"The paradigm of cancer treatment must now shift beyond survival to encompass both survival and quality of life," said Professor Shin Dong-wook. "These findings could serve as important data for establishing individualized fracture prevention and management policies."

Professor Kim Sung-hye said, "This suggests that continuous management and proactive treatment are necessary to prevent fractures in esophageal cancer survivors."

Professor Cho Jong-ho emphasized, "Fracture risk becomes clearly evident starting one year after esophageal cancer surgery. Long-term health management remains important even after cancer treatment."
