Active clinical trials for "Gastrointestinal Neoplasms"

This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.

Through exploring the specific genetic mutations in the upper gastrointestinal tract tumors with a family history and specific clinical pathological types，we establish a complete family and follow-up system，in order to improve the screening criteria of Chinese hereditary upper gastrointestinal tumors and carry on primary prevention of disease.

Extramural venous invasion (EMVI) is the spread of microscopic tumour cells into the veins around the tumour. Rectal cancer treatment has improved greatly over recent years. However, it is important for us to learn as much about the tumours as possible in order to develop newer therapies. Current treatments may benefit from new genetic information relating to the cancer. We hope to identify genetic differences in certain types of rectal cancer which will allow future treatments.

The purpose of this study is to clarify the relationship bone marrow-derived cells and the formation of the tumors, and the role of these cells in regeneration of epithelial cells in the gastrointestinal tract.
