The National Cancer Center Hospital launched a clinical study in August to transplant intestinal flora from healthy donors to patients with progressive esophageal and stomach cancers.

Researchers believe that disruptions in bacterial flora may contribute to the development of colorectal cancer. The study aims to determine whether restoring a healthy intestinal environment can enhance the effectiveness of immunotherapy drugs used in cancer treatment. The trial is expected to run until November 2027.

Approximately 100 trillion bacteria, representing around 1,000 different species, reside in the human intestine. The community, known as intestinal flora, is believed to play a key role in promoting overall health. Factors such as stress, fatigue, unbalanced diet and aging can disrupt the balance of these bacteria, potentially leading to various diseases.
